commit 97d917879d7f92df09c3f21fd54609a8bcd654b2 upstream.
We took sound_oss_mutex around the calls of unregister_sound_special() at unregistering OSS devices. This may, however, lead to a deadlock, because we manage the card release via the card's device object, and the release may happen at unregister_sound_special() call -- which will take sound_oss_mutex again in turn.
Although the deadlock might be fixed by relaxing the rawmidi mutex in the previous commit, it's safer to move unregister_sound_special() calls themselves out of the sound_oss_mutex, too. The call is race-safe as the function has a spinlock protection by itself.

--------------------------------
commit a70aef7982b012e86dfd39fbb235e76a21ae778a upstream.
The register_mutex taken around the dev_unregister callback call in snd_rawmidi_free() may potentially lead to a mutex deadlock, when OSS emulation and a hot unplug are involved.
Since the mutex doesn't protect the actual race (as the registration itself is already protected by another means), let's drop it.

commit 6382da0828995af87aa8b8bef28cc61aceb4aff3 upstream.
When the driver hits -ENOMEM at allocating a URB or a buffer, it aborts and goes to the error path that releases the all previously allocated resources. However, when -ENOMEM hits at the middle of the sync EP URB allocation loop, the partially allocated URBs might be left without released, because ep->nurbs is still zero at that point.
Fix it by setting ep->nurbs at first, so that the error handler loops over the full URB list.

commit 568be8aaf8a535f79c4db76cabe17b035aa2584d upstream.
At an error path to release URB buffers and contexts, the driver might hit a NULL dererence for u->urb pointer, when u->buffer_size has been already set but the actual URB allocation failed.
Fix it by adding the NULL check of urb. Also, make sure that buffer_size is cleared after the error path or the close.

After some feedback from users with Dell Precision 5530 machines, this patch reverts the previous change to add ALC289_FIXUP_DUAL_SPK. While it improved the speaker output quality, it caused the headphone jack to have an audible "pop" sound when power saving was toggled.

This is the opposite case of kernel bugzilla 216301. If we mmap a file using cache=none and then proceed to update the mmapped area these updates are not reflected in a later pread() of that part of the file. To fix this we must first destage any dirty pages in the range before we allow the pread() to proceed.

For reliable operation across the full range of supported interface rates, the AD5593R needs a STOP condition between address write, and data read (like show in the datasheet Figure 40) so in turn i2c_smbus_read_word_swapped cannot be used.
While at it, a simple helper was added to make the code simpler.

commit 7f4f1096d5921f5d90547596f9ce80e0b924f887 upstream.
After the result of the previous conversion is read the chip automatically starts a new conversion and doesn't accept new i2c transfers until this conversion is completed which makes the function return failure.
So add an early return iff the programming of the new address isn't needed. Note this will not fix the problem in general, but all cases that are currently used. Once this changes we get the failure back, but this can be addressed when the need arises.

commit f4f43f01cff2f29779343ade755191afd2581c77 upstream.
Some of the supported devices have 4 or 2 LSB trailing bits that should not be taken into account. Hence we need to shift these bits out which fits perfectly on the scan type shift property. This change fixes both raw and buffered reads.

commit 7b4ab4abcea4c0c10b25187bf2569e5a07e9a20c upstream.
The DPS310 chip has been observed to get "stuck" such that pressure and temperature measurements are never indicated as "ready" in the MEAS_CFG register. The only solution is to reset the device and try again. In order to avoid continual failures, use a boolean flag to only try the reset after timeout once if errors persist.

--------------------------------
commit 37d49519b41405b08748392c6a7f193d9f77ecd2 upstream.
The Lenovo OneLink+ Dock contains two VL812 USB3.0 controllers: 17ef:1018 upstream 17ef:1019 downstream
These hubs suffer from two separate problems:
1) After the host system was suspended and woken up, the hubs appear to be in a random state. Some downstream ports (both internal to the built-in audio and network controllers, and external to USB sockets) may no longer be functional. The exact list of disabled ports (if any) changes from wakeup to wakeup. Ports remain in that state until the dock is power-cycled, or until the laptop is rebooted.
Wakeup sources connected to the hubs (keyboard, WoL on the integrated gigabit controller) will wake the system up from suspend, but they may no longer work after wakeup (and in that case will no longer work as wakeup source in a subsequent suspend-wakeup cycle).
This issue appears in the logs with messages such as:
usb 1-6.1-port4: cannot disable (err = -71) usb 1-6-port2: cannot disable (err = -71) usb 1-6.1: clear tt 1 (80c0) error -71 usb 1-6-port4: cannot disable (err = -71) usb 1-6.4: PM: dpm_run_callback(): usb_dev_resume+0x0/0x10 [usbcore] returns -71 usb 1-6.4: PM: failed to resume async: error -71 usb 1-7: reset full-speed USB device number 5 using xhci_hcd usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: cannot reset (err = -71) usb 1-6.1-port1: Cannot enable.

Maybe the USB cable is bad? usb 1-6.1-port1: cannot disable (err = -71)
2) Some USB devices cannot be enumerated properly. So far I have only seen the issue with USB 3.0 devices. The same devices work without problem directly connected to the host system, to other systems or to other hubs (even when those hubs are connected to the OneLink+ dock).
One very reliable reproducer is this USB 3.0 HDD enclosure: 152d:9561 JMicron Technology Corp. / JMicron USA Technology Corp. Mobius
I have seen it happen sporadically with other USB 3.0 enclosures, with controllers from different manufacturers, all self-powered.

Through trial and error, I found that the USB_QUIRK_RESET_RESUME solved the second issue. Further testing then uncovered the first issue. Test results are summarized in this table:
======================================================================================= Settings USB2 hotplug USB3 hotplug State after waking up ---------------------------------------------------------------------------------------
power/control=auto works fails broken
usbcore.autosuspend=-1 works works broken OR power/control=on
power/control=auto works (1) works (1) works and USB_QUIRK_RESET_RESUME
power/control=on works works works and USB_QUIRK_RESET_RESUME
HUB_QUIRK_DISABLE_AUTOSUSPEND works works works and USB_QUIRK_RESET_RESUME
=======================================================================================
In those results, the power/control settings are applied to both hubs, both on the USB2 and USB3 side, before each test.
From those results, USB_QUIRK_RESET_RESUME is required to reset the hubs properly after a suspend-wakeup cycle, and the hubs must not autosuspend to work around the USB3 issue.
A secondary effect of USB_QUIRK_RESET_RESUME is to prevent the hubs' upstream links from suspending (the downstream ports can still suspend). This secondary effect is used in results (1). It is enough to solve the USB3 problem.
Setting USB_QUIRK_RESET_RESUME on those hubs is the smallest patch that solves both issues.
Prior to creating this patch, I have used the USB_QUIRK_RESET_RESUME via the kernel command line for over a year without noticing any side effect.
Thanks to Oliver Neukum @Suse for explanations of the operations of USB_QUIRK_RESET_RESUME, and requesting more testing.

commit cd7f30e174d09a02ca2afa5ef093fb0f0352e0d8 upstream.
flush_comp is initialized when CMD_FLUSH_QUEUE is sent to the device and completed when the device sends CMD_FLUSH_QUEUE_RESP.
This causes completion of uninitialized completion if the device sends CMD_FLUSH_QUEUE_RESP before CMD_FLUSH_QUEUE is ever sent (e.g. as a response to a flush by a previously bound driver, or a misbehaving device).
Fix that by initializing flush_comp in kvaser_usb_init_one() like the other completions.
This issue is only triggerable after RX URBs have been set up, i.e. the interface has been opened at least once.

--------------------------------
commit 1499ecaea9d2ba68d5e18d80573b4561a8dc4ee7 upstream.
For command events read from the device, kvaser_usb_leaf_read_bulk_callback() verifies that cmd->len does not exceed the size of the received data, but the actual kvaser_cmd handlers will happily read any kvaser_cmd fields without checking for cmd->len.
This can cause an overread if the last cmd in the buffer is shorter than expected for the command type (with cmd->len showing the actual short size).
Maximum overread seems to be 22 bytes (CMD_LEAF_LOG_MESSAGE), some of which are delivered to userspace as-is.
Fix that by verifying the length of command before handling it.
This issue can only occur after RX URBs have been set up, i.e. the interface has been opened at least once.

commit 455561fb618fde40558776b5b8435f9420f335db upstream.
The TX queue seems to be implicitly flushed by the hardware during bus-off or bus-off recovery, but the driver does not reset the TX bookkeeping.
Despite not resetting TX bookkeeping the driver still re-enables TX queue unconditionally, leading to "cannot find free context" / NETDEV_TX_BUSY errors if the TX queue was full at bus-off time.
Fix that by resetting TX bookkeeping on CAN restart.
Tested with 0bfd:0124 Kvaser Mini PCI Express 2xHS FW 4.18.778.

can_restart() expects CMD_START_CHIP to set the error state to ERROR_ACTIVE as it calls netif_carrier_on() immediately afterwards.
Otherwise the user may immediately trigger restart again and hit a BUG_ON() in can_restart().

Unfortunately this has also lead to fail to initialize some cards, which are allowed to require 100KHz to work. So, let's fix the problem by changing the minimal supported clock rate to 100KHz.

commit eef6ec9bf390e836a6c4029f3620fe49528aa1fe upstream.
This patch fixes a race by using ls_cb_mutex around the bit operations and conditional code blocks for LSFL_CB_DELAY.
The function dlm_callback_stop() expects to stop all callbacks and flush all currently queued onces. The set_bit() is not enough because there can still be queue_work() after the workqueue was flushed. To avoid queue_work() after set_bit(), surround both by ls_cb_mutex.

commit be6e2b5734a425941fcdcdbd2a9337be498ce2cf upstream.
This fixes broken atomic checks which cause a race between the release-timer and processing of hid input.
I noticed that contacts were sometimes sticking, even with the "sticky fingers" quirk enabled. This fixes that problem.

commit f74c7557ed0d321947e8bb4e9d47c1013f8b2227 upstream.
Some EC based devices (e.g. Fingerpint MCU) can jump to RO part of the firmware (intentionally or due to device reboot). The RO part doesn't change during the device lifecycle, so it won't support newer version of EC_CMD_GET_NEXT_EVENT command.
Function cros_ec_query_all() is responsible for finding maximum supported MKBP event version. It's usually called when the device is running RW part of the firmware, so the command version can be potentially higher than version supported by the RO.
The problem was fixed by updating maximum supported version when the device returns EC_RES_INVALID_VERSION (mapped to -ENOPROTOOPT). That way the kernel will use highest common version supported by RO and RW.

Slimbus streams are first prepared and then enabled, so the cleanup path should reverse it. The unprepare sets stream->num_ports to 0 and frees the stream->ports. Calling disable after unprepare was not really effective (channels was not deactivated) and could lead to further issues due to making transfers on unprepared stream.

commit 8478ed5844588703a1a4c96a004b1525fbdbdd5e upstream.
On recent kernels, the PM8058 L16 (or any other PM8058 LDO-regulator) does not come up if they are supplied by an SMPS-regulator. This is not very strange since the regulators are registered in a long array and the L-regulators are registered before the S-regulators, and if an L-regulator defers, it will never get around to registering the S-regulator that it needs.
See arch/arm/boot/dts/qcom-apq8060-dragonboard.dts:
pm8058-regulators { (...) vdd_l13_l16-supply = <&pm8058_s4>; (...)
Ooops.
Fix this by moving the PM8058 S-regulators first in the array.
Do the same for the PM8901 S-regulators (though this is currently not causing any problems with out device trees) so that the pattern of registration order is the same on all PMnnnn chips.

Fix port I/O string accessors such as `insb', `outsb', etc. which use the physical PCI port I/O address rather than the corresponding memory mapping to get at the requested location, which in turn breaks at least accesses made by our parport driver to a PCIe parallel port such as:

For simplicity address the problem by adding PCI_IOBASE to the physical address requested in the respective wrapper macros only, observing that the raw accessors such as `__insb', `__outsb', etc. are not supposed to be used other than by said macros. Remove the cast to `long' that is no longer needed on `addr' now that it is used as an offset from PCI_IOBASE and add parentheses around `addr' needed for predictable evaluation in macro expansion. No need to make said adjustments in separate changes given that current code is gravely broken and does not ever work.

commit 9e2e6042a7ec6504fe8e366717afa2f40cf16488 upstream.
Commit 2139619bcad7 ("riscv: mmap with PROT_WRITE but no PROT_READ is invalid") made mmap() return EINVAL if PROT_WRITE was set wihtout PROT_READ with the justification that a write-only PTE is considered a reserved PTE permission bit pattern in the privileged spec. This check is unnecessary since we let VM_WRITE imply VM_READ on RISC-V, and it is inconsistent with other architectures that don't support write-only PTEs, creating a potential software portability issue. Just remove the check altogether and let PROT_WRITE imply PROT_READ as is the case on other architectures.
Note that this also allows PROT_WRITE|PROT_EXEC mappings which were disallowed prior to the aforementioned commit; PROT_READ is implied in such mappings as well.

RISC-V does not presently have write-only mappings as that PTE bit pattern is considered reserved in the privileged spec, so allow handling of read faults in VMAs that have VM_WRITE without VM_READ in order to be consistent with other architectures that have similar limitations.

commit 6d6e732835db92e66c28dbcf258a7e3d3c71420d upstream.
Restore the display mode whne resuming from suspend. Currently, the display remains dark.
On resume, the CRTC's mode does not change, but the 'active' flag changes to 'true'. Taking this into account when considering a mode switch restores the display mode.
The bug is reproducable by using Gnome with udl and observing the adapter's suspend/resume behavior.
Actually, the whole check added in udl_simple_display_pipe_enable() about the crtc_state->mode_changed was bogus. We should drop the whole check and always apply the mode change in this function.
[ tiwai -- Drop the mode_changed check entirely instead, per Daniel's suggestion ]

commit deb0f6562884b5b4beb883d73e66a7d3a1b96d99 upstream.
Commit c462ac288f2c ("mm: Introduce arch_validate_flags()") added a late check in mmap_region() to let architectures validate vm_flags. The check needs to happen after calling ->mmap() as the flags can potentially be modified during this callback.
If arch_validate_flags() check fails we unmap and free the vma. However, the error path fails to undo the ->mmap() call that previously succeeded and depending on the specific ->mmap() implementation this translates to reference increments, memory allocations and other operations what will not be cleaned up.
There are several places (mainly device drivers) where this is an issue. However, one specific example is bpf_map_mmap() which keeps count of the mappings in map->writecnt. The count is incremented on ->mmap() and then decremented on vm_ops->close(). When arch_validate_flags() fails this count is off since bpf_map_mmap_close() is never called.
One can reproduce this issue in arm64 devices with MTE support. Here the vm_flags are checked to only allow VM_MTE if VM_MTE_ALLOWED has been set previously. From userspace then is enough to pass the PROT_MTE flag to mmap() syscall to trigger the arch_validate_flags() failure.
The following program reproduces this issue:
#include <stdio.h> #include <unistd.h> #include <linux/unistd.h> #include <linux/bpf.h> #include <sys/mman.h>
int main(void) { union bpf_attr attr = { .map_type = BPF_MAP_TYPE_ARRAY, .key_size = sizeof(int), .value_size = sizeof(long long), .max_entries = 256, .map_flags = BPF_F_MMAPABLE, }; int fd;
fd = syscall(__NR_bpf, BPF_MAP_CREATE, &attr, sizeof(attr)); mmap(NULL, 4096, PROT_WRITE | PROT_MTE, MAP_SHARED, fd, 0);
return 0; }
By manually adding some log statements to the vm_ops callbacks we can confirm that when passing PROT_MTE to mmap() the map->writecnt is off upon ->release():
With PROT_MTE flag: root@debian:~# ./bpf-test [ 111.263874] bpf_map_write_active_inc: map=9 writecnt=1 [ 111.288763] bpf_map_release: map=9 writecnt=1
Without PROT_MTE flag: root@debian:~# ./bpf-test [ 157.816912] bpf_map_write_active_inc: map=10 writecnt=1 [ 157.830442] bpf_map_write_active_dec: map=10 writecnt=0 [ 157.832396] bpf_map_release: map=10 writecnt=0
This patch fixes the above issue by calling vm_ops->close() when the arch_validate_flags() check fails, after this we can proceed to unmap and free the vma on the error path.

--------------------------------
commit 0e32818397426a688f598f35d3bc762eca6d7592 upstream.
When pci_assign_resource() is unable to assign resources to a BAR, it uses pci_revert_fw_address() to fall back to a firmware assignment (if any). Previously pci_revert_fw_address() assumed all addresses could reach the device, but this is not true if the device is below a bridge that only forwards addresses within its windows.
This problem was observed on a Tyan Tomcat IV S1564D system where the BIOS did not assign valid addresses to several bridges and USB devices:
pci 0000:00:11.0: PCI-to-PCIe bridge to [bus 01-ff] pci 0000:00:11.0: bridge window [io 0xe000-0xefff] pci 0000:01:00.0: PCIe Upstream Port to [bus 02-ff] pci 0000:01:00.0: bridge window [io 0x0000-0x0fff] # unreachable pci 0000:02:02.0: PCIe Downstream Port to [bus 05-ff] pci 0000:02:02.0: bridge window [io 0x0000-0x0fff] # unreachable pci 0000:05:00.0: PCIe-to-PCI bridge to [bus 06-ff] pci 0000:05:00.0: bridge window [io 0x0000-0x0fff] # unreachable pci 0000:06:08.0: USB UHCI 1.1 pci 0000:06:08.0: BAR 4: [io 0xfce0-0xfcff] # unreachable pci 0000:06:08.1: USB UHCI 1.1 pci 0000:06:08.1: BAR 4: [io 0xfce0-0xfcff] # unreachable pci 0000:06:08.0: can't claim BAR 4 [io 0xfce0-0xfcff]: no compatible bridge window pci 0000:06:08.1: can't claim BAR 4 [io 0xfce0-0xfcff]: no compatible bridge window
During the first pass of assigning unassigned resources, there was not enough I/O space available, so we couldn't assign the 06:08.0 BAR and reverted to the firmware assignment (still unreachable). Reverting the 06:08.1 assignment failed because it conflicted with 06:08.0:
pci 0000:00:11.0: bridge window [io 0xe000-0xefff] pci 0000:01:00.0: no space for bridge window [io size 0x2000] pci 0000:02:02.0: no space for bridge window [io size 0x1000] pci 0000:05:00.0: no space for bridge window [io size 0x1000] pci 0000:06:08.0: BAR 4: no space for [io size 0x0020] pci 0000:06:08.0: BAR 4: trying firmware assignment [io 0xfce0-0xfcff] pci 0000:06:08.1: BAR 4: no space for [io size 0x0020] pci 0000:06:08.1: BAR 4: trying firmware assignment [io 0xfce0-0xfcff] pci 0000:06:08.1: BAR 4: [io 0xfce0-0xfcff] conflicts with 0000:06:08.0 [io 0xfce0-0xfcff]
A subsequent pass assigned valid bridge windows and a valid 06:08.1 BAR, but left the 06:08.0 BAR alone, so the UHCI device was still unusable:
pci 0000:00:11.0: bridge window [io 0xe000-0xefff] released pci 0000:00:11.0: bridge window [io 0x1000-0x2fff] # reassigned pci 0000:01:00.0: bridge window [io 0x1000-0x2fff] # reassigned pci 0000:02:02.0: bridge window [io 0x2000-0x2fff] # reassigned pci 0000:05:00.0: bridge window [io 0x2000-0x2fff] # reassigned pci 0000:06:08.0: BAR 4: assigned [io 0xfce0-0xfcff] # left alone pci 0000:06:08.1: BAR 4: assigned [io 0x2000-0x201f] ... uhci_hcd 0000:06:08.0: host system error, PCI problems? uhci_hcd 0000:06:08.0: host controller process error, something bad happened! uhci_hcd 0000:06:08.0: host controller halted, very bad! uhci_hcd 0000:06:08.0: HCRESET not completed yet! uhci_hcd 0000:06:08.0: HC died; cleaning up
If the address assigned by firmware is not reachable because it's not within upstream bridge windows, fail instead of assigning the unusable address from firmware.

commit 331cd9461412e103d07595a10289de90004ac890 upstream.
When enabling quotas, at btrfs_quota_enable(), after committing the transaction, we change fs_info->quota_root to point to the quota root we created and set BTRFS_FS_QUOTA_ENABLED at fs_info->flags. Then we try to start the qgroup rescan worker, first by initializing it with a call to qgroup_rescan_init() - however if that fails we end up freeing the quota root but we leave fs_info->quota_root still pointing to it, this can later result in a use-after-free somewhere else.
We have previously set the flags BTRFS_FS_QUOTA_ENABLED and BTRFS_QGROUP_STATUS_FLAG_ON, so we can only fail with -EINPROGRESS at btrfs_quota_enable(), which is possible if someone already called the quota rescan ioctl, and therefore started the rescan worker.
So fix this by ignoring an -EINPROGRESS and asserting we can't get any other error.

commit da35fe96d12d15779f3cb74929b7ed03941cf983 upstream.
This patch increases the threshold that limits the reserved root space from 0.2% to 12.5% by using simple shift operation.
Typically Android sets 128MB, but if the storage capacity is 32GB, 0.2% which is around 64MB becomes too small. Let's relax it.

If we enable CONFIG_F2FS_CHECK_FS config, it will trigger a kernel panic instead of warning.
The root cause is: in fuzzed image, SIT table is inconsistent with inode mapping table, result in triggering such warning during SIT table update.
This patch introduces a new flag DATA_GENERIC_ENHANCE_UPDATE, w/ this flag, data block recovery flow can check destination blkaddr's validation in SIT table, and skip f2fs_replace_block() to avoid inconsistent status.

Clarify the details around the automatic variable initialization modes available. Specifically this details the values used for pattern init and expands on the rationale for zero init safety. Additionally makes zero init the default when available.

commit f02003c860d921171be4a27e2893766eb3bc6871 upstream.
Currently under Clang, CC_HAS_AUTO_VAR_INIT_ZERO requires an extra -enable flag compared to CC_HAS_AUTO_VAR_INIT_PATTERN. GCC 12[1] will not, and will happily ignore the Clang-specific flag. However, its presence on the command-line is both cumbersome and confusing. Due to GCC's tolerant behavior, though, we can continue to use a single Kconfig cc-option test for the feature on both compilers, but then drop the Clang-specific option in the Makefile.
In other words, this patch does not change anything other than making the compiler command line shorter once GCC supports -ftrivial-auto-var-init=zero.

Clang 16 and later will warn when it is used, which will cause Kconfig to think it can't use -ftrivial-auto-var-init=zero at all. Check for whether it is required and only use it when so.

commit 34fc8768ec6089565d6d73bad26724083cecf7bd upstream.
LIFO wakeup order is unfair and sometimes leads to a journal user not being able to get a journal handle for hundreds of transactions in a row.
FIFO wakeup can make things more fair.

As in 'jbd2_fc_wait_bufs' if buffer isn't uptodate, will return -EIO without update 'journal->j_fc_off'. But 'jbd2_fc_release_bufs' will release buffer head from ‘j_fc_off - 1’ if 'bh' is NULL will terminal release which will lead to buffer head buffer head reference count leak. To solve above issue, update 'journal->j_fc_off' before return -EIO.

commit 4bb26f2885ac6930984ee451b952c5a6042f2c0e upstream.
When inode is created and written to using direct IO, there is nothing to clear the EXT4_STATE_MAY_INLINE_DATA flag. Thus when inode gets truncated later to say 1 byte and written using normal write, we will try to store the data as inline data. This confuses the code later because the inode now has both normal block and inline data allocated and the confusion manifests for example as:

The problem can be reproduced by xfstest ext4/026 when iversion is enabled. Fix it by not calling inode_inc_iversion() for EXT4_EA_INODE_FL inodes in ext4_mark_iloc_dirty().

commit d1052d236eddf6aa851434db1897b942e8db9921 upstream.
In our product environment, we encounter some jbd hung waiting handles to stop while several writters were doing memory reclaim for buffer head allocation in delay alloc write path. Ext4 do buffer head allocation with holding transaction handle which may be blocked too long if the reclaim works not so smooth. According to our bcc trace, the reclaim time in buffer head allocation can reach 258s and the jbd transaction commit also take almost the same time meanwhile. Except for these extreme cases, we often see several seconds delays for cgroup memory reclaim on our servers. This is more likely to happen considering docker environment.
One thing to note, the allocation of buffer heads is as often as page allocation or more often when blocksize less than page size. Just like page cache allocation, we should also place the buffer head allocation before startting the handle.

commit 747f7a2901174c9afa805dddfb7b24db6f65e985 upstream.
The KLP transition code depends on the TIF_PATCH_PENDING and the task->patch_state to stay in sync. On a normal (forward) transition, TIF_PATCH_PENDING will be set on every task in the system, while on a reverse transition (after a failed forward one) first TIF_PATCH_PENDING will be cleared from every task, followed by it being set on tasks that need to be transitioned back to the original code.
However, the fork code copies over the TIF_PATCH_PENDING flag from the parent to the child early on, in dup_task_struct and setup_thread_stack. Much later, klp_copy_process will set child->patch_state to match that of the parent.
However, the parent's patch_state may have been changed by KLP loading or unloading since it was initially copied over into the child.
This results in the KLP code occasionally hitting this warning in klp_complete_transition:
for_each_process_thread(g, task) { WARN_ON_ONCE(test_tsk_thread_flag(task, TIF_PATCH_PENDING)); task->patch_state = KLP_UNDEFINED; }
Set, or clear, the TIF_PATCH_PENDING flag in the child task depending on whether or not it is needed at the time klp_copy_process is called, at a point in copy_process where the tasklist_lock is held exclusively, preventing races with the KLP code.
The KLP code does have a few places where the state is changed without the tasklist_lock held, but those should not cause problems because klp_update_patch_state(current) cannot be called while the current task is in the middle of fork, klp_check_and_switch_task() which is called under the pi_lock, which prevents rescheduling, and manipulation of the patch state of idle tasks, which do not fork.
This should prevent this warning from triggering again in the future, and close the race for both normal and reverse transitions.

commit 0ce0638edf5ec83343302b884fa208179580700a upstream.
When executing following commands like what document said, but the log "#### all functions enabled ####" was not shown as expect: 1. Set a 'mod' filter: $ echo 'write*:mod:ext3' > /sys/kernel/tracing/set_ftrace_filter 2. Invert above filter: $ echo '!write*:mod:ext3' >> /sys/kernel/tracing/set_ftrace_filter 3. Read the file: $ cat /sys/kernel/tracing/set_ftrace_filter
By some debugging, I found that flag FTRACE_HASH_FL_MOD was not unset after inversion like above step 2 and then result of ftrace_hash_empty() is incorrect.

commit fa8f4a89736b654125fb254b0db753ac68a5fced upstream.
If a page is partially read, and then the splice system call is run against the ring buffer, it will always fail to read, no matter how much is in the ring buffer. That's because the code path for a partial read of the page does will fail if the "full" flag is set.
The splice system call wants full pages, so if the read of the ring buffer is not yet full, it should return zero, and the splice will block. But if a previous read was done, where the beginning has been consumed, it should still be given to the splice caller if the rest of the page has been written to.
This caused the splice command to never consume data in this scenario, and let the ring buffer just fill up and lose events.

commit ec0bbc5ec5664dcee344f79373852117dc672c86 upstream.
The wake up waiters only checks the "wakeup_full" variable and not the "full_waiters_pending". The full_waiters_pending is set when a waiter is added to the wait queue. The wakeup_full is only set when an event is triggered, and it clears the full_waiters_pending to avoid multiple calls to irq_work_queue().
The irq_work callback really needs to check both wakeup_full as well as full_waiters_pending such that this code can be used to wake up waiters when a file is closed that represents the ring buffer and the waiters need to be woken up.

On closing of a file that represents a ring buffer or flushing the file, there may be waiters on the ring buffer that needs to be woken up and exit the ring_buffer_wait() function.
Add ring_buffer_wake_waiters() to wake up the waiters on the ring buffer and allow them to exit the wait loop.

commit c0a581d7126c0bbc96163276f585fd7b4e4d8d0e upstream.
It was found that some tracing functions in kernel/trace/trace.c acquire an arch_spinlock_t with preemption and irqs enabled. An example is the tracing_saved_cmdlines_size_read() function which intermittently causes a "BUG: using smp_processor_id() in preemptible" warning when the LTP read_all_proc test is run.
That can be problematic in case preemption happens after acquiring the lock. Add the necessary preemption or interrupt disabling code in the appropriate places before acquiring an arch_spinlock_t.
The convention here is to disable preemption for trace_cmdline_lock and interupt for max_lock.

commit 5d2569cb4a65c373896ec0217febdf88739ed295 upstream.
Software that has run before the USB4 CM in Linux runs may have disabled hotplug events for a given lane adapter.
Other CMs such as that one distributed with Windows 11 will enable hotplug events. Do the same thing in the Linux CM which fixes hotplug events on "AMD Pink Sardine".

commit d953540430c5af57f5de97ea9e36253908204027 upstream.
Drop pending exceptions and events queued for re-injection when leaving nested guest mode, even if the "exit" is due to VM-Fail, SMI, or forced by host userspace. Failure to purge events could result in an event belonging to L2 being injected into L1.
This _should_ never happen for VM-Fail as all events should be blocked by nested_run_pending, but it's possible if KVM, not the L1 hypervisor, is the source of VM-Fail when running vmcs02.
SMI is a nop (barring unknown bugs) as recognition of SMI and thus entry to SMM is blocked by pending exceptions and re-injected events.
Forced exit is definitely buggy, but has likely gone unnoticed because userspace probably follows the forced exit with KVM_SET_VCPU_EVENTS (or some other ioctl() that purges the queue).

commit eba9799b5a6efe2993cf92529608e4aa8163d73b upstream.
Deliberately truncate the exception error code when shoving it into the VMCS (VM-Entry field for vmcs01 and vmcs02, VM-Exit field for vmcs12). Intel CPUs are incapable of handling 32-bit error codes and will never generate an error code with bits 31:16, but userspace can provide an arbitrary error code via KVM_SET_VCPU_EVENTS. Failure to drop the bits on exception injection results in failed VM-Entry, as VMX disallows setting bits 31:16. Setting the bits on VM-Exit would at best confuse L1, and at worse induce a nested VM-Entry failure, e.g. if L1 decided to reinject the exception back into L2.

commit d517cdeb904ddc0cbebcc959d43596426cac40b0 upstream.
In the greybus audio_helper code, the debugfs file for the dapm has the potential to be removed and memory will be leaked. There is also the very real potential for this code to remove ALL debugfs entries from the system, and it seems like this is what will really happen if this code ever runs. This all is very wrong as the greybus audio driver did not create this debugfs file, the sound core did and controls the lifespan of it.
So remove all of the debugfs logic from the audio_helper code as there's no way it could be correct. If this really is needed, it can come back with a fixup for the incorrect usage of the debugfs_lookup() call which is what caused this to be noticed at all.

commit 8ba9249396bef37cb68be9e8dee7847f1737db9d upstream.
As it turns out: while Nvidia does actually have interlacing knobs on their GPU still pretty much no current GPUs since Volta actually support it. Trying interlacing on these GPUs will result in NVDisplay being quite unhappy like so:
nouveau 0000:1f:00.0: disp: chid 0 stat 00004802 reason 4 [INVALID_ARG] mthd 2008 data 00000001 code 00080000 nouveau 0000:1f:00.0: disp: chid 0 stat 10005080 reason 5 [INVALID_STATE] mthd 0200 data 00000001 code 00000001
So let's fix this by following the same behavior Nvidia's driver does and disable interlacing entirely.

--------------------------------
commit 540dfd188ea2940582841c1c220bd035a7db0e51 upstream.
nouveau_bo_init() is backed by ttm_bo_init() and ferries its return code back to the caller. On failures, ttm will call nouveau_bo_del_ttm() and free the memory.Thus, when nouveau_bo_init() returns an error, the gem object has already been released. Then the call to nouveau_bo_ref() will use the freed "nvbo->bo" and lead to a use-after-free bug.
We should delete the call to nouveau_bo_ref() to avoid the use-after-free.

[ Upstream commit abec3d015fdfb7c63105c7e1c956188bf381aa55 ]
Since userfaultfd doesn't implement a write operation, it is more appropriate to open it read-only.
When userfaultfds are opened read-write like it is now, and such fd is passed from one process to another, SELinux will check both read and write permissions for the target process, even though it can't actually do any write operation on the fd later.
Inspired by the following bug report, which has hit the SELinux scenario described above: https://bugzilla.redhat.com/show_bug.cgi?id=1974559

In error case in bridge_platform_create after calling platform_device_add()/platform_device_add_data()/ platform_device_add_resources(), release the failed 'pdev' or it will be leak, call platform_device_put() to fix this problem.
Besides, 'pdev' is divided into 'pdev_wd' and 'pdev_bd', use platform_device_unregister() to release sgi_w1 resources when xtalk-bridge registration fails.

[ Upstream commit f020d9570a04df0762a2ac5c50cf1d8c511c9164 ]
When peer delete failed in a disconnect operation, use-after-free detected by KFENCE in below log. It is because for each vdev_id and address, it has only one struct ath10k_peer, it is allocated in ath10k_peer_map_event(). When connected to an AP, it has more than one HTT_T2H_MSG_TYPE_PEER_MAP reported from firmware, then the array peer_map of struct ath10k will be set muti-elements to the same ath10k_peer in ath10k_peer_map_event(). When peer delete failed in ath10k_sta_state(), the ath10k_peer will be free for the 1st peer id in array peer_map of struct ath10k, and then use-after-free happened for the 2nd peer id because they map to the same ath10k_peer.
And clean up all peers in array peer_map for the ath10k_peer, then user-after-free disappeared

From 'IEEE Std 802.11-2020 section 11.8.8.4.1': The mesh channel switch may be triggered by the need to avoid interference to a detected radar signal, or to reassign mesh STA channels to ensure the MBSS connectivity.
A 20/40 MHz MBSS may be changed to a 20 MHz MBSS and a 20 MHz MBSS may be changed to a 20/40 MHz MBSS.
Since the standard allows the change of bandwidth during the channel switch in mesh, remove the bandwidth check present in ieee80211_set_csa_beacon.

[ Upstream commit 10888140f09c3472146dc206accd0cfa051d0ed4 ]
Enlarging the size of 'struct btmtk_hci_wmt_cmd' makes it no longer fit on the kernel stack, as seen from this compiler warning:
drivers/bluetooth/btusb.c:3365:12: error: stack frame size of 1036 bytes in function 'btusb_mtk_hci_wmt_sync' [-Werror,-Wframe-larger-than=]
Change the function to dynamically allocate the buffer instead. As there are other sleeping functions called from the same location, using GFP_KERNEL should be fine here, and the runtime overhead should not matter as this is rarely called.
Unfortunately, I could not figure out why the message size is increased in the previous patch. Using dynamic allocation means any size is possible now, but there is still a range check that limits the total size (including the five-byte header) to 255 bytes, so whatever was intended there is now undone.

There some bounds checking to ensure that "map_addr" is not out of bounds before the start of the loop. But the checking needs to be done as we iterate through the loop because "map_addr" gets larger as we iterate.

Since [1], controller's busy flag isn't set anymore when the __spi_transfer_message_noqueue() is used instead of the __spi_pump_transfer_message() logic for spi_sync transfers.
Since the pow2 clock ops were limited to only be available when a transfer is ongoing (between prepare_transfer_hardware and unprepare_transfer_hardware callbacks), the only way to track this down is to check for the controller cur_msg.

[ Upstream commit a37a32583e282d8d815e22add29bc1e91e19951a ]
When trying to finish resolving a struct member, btf_struct_resolve saves the member type id in a u16 temporary variable. This truncates the 32 bit type id value if it exceeds UINT16_MAX.
As a result, structs that have members with type ids > UINT16_MAX and which need resolution will fail with a message like this:
[67414] STRUCT ff_device size=120 vlen=12 effect_owners type_id=67434 bits_offset=960 Member exceeds struct_size
Fix this by changing the type of last_member_type_id to u32.

[ Upstream commit 3124d320c22f3f4388d9ac5c8f37eaad0cefd6b1 ]
syzbot is reporting NULL pointer dereference at hci_uart_tty_close() [1], for rcu_sync_enter() is called without rcu_sync_init() due to hci_uart_tty_open() ignoring percpu_init_rwsem() failure.
While we are at it, fix that hci_uart_register_device() ignores percpu_init_rwsem() failure and hci_uart_unregister_device() does not call percpu_free_rwsem().

[ Upstream commit 55b5ee3357d7bb98ee578cf9b84a652e7a1bc199 ]
The number of spatial streams used when acting as a beamformee in VHT mode are reported by the firmware as 7 (8 sts - 1) both in IPQ6018 and IPQ8074 which respectively have 2 and 4 sts each. So the firmware should report 1 (2 - 1) and 3 (4 - 1).
Fix this by checking that the number of VHT beamformee sts reported by the firmware is not greater than the number of receiving antennas - 1. The fix is based on the same approach used in this same function for sanitizing the number of sounding dimensions reported by the firmware.
Without this change, acting as a beamformee in VHT mode is not working properly.

In preparation for reducing the use of ksize(), record the actual allocation size for later memcpy(). This avoids copying extra (uninitialized!) bytes into the patch buffer when the requested allocation size isn't exactly the size of a kmalloc bucket. Additionally, fix potential future issues where runtime bounds checking will notice that the buffer was allocated to a smaller value than returned by ksize().

[ Upstream commit 30ea703a38ef76ca119673cd8bdd05c6e068e2ac ]
Include the header containing the prototype of init_ia32_feat_ctl(), solving the following warning:
$ make W=1 arch/x86/kernel/cpu/feat_ctl.o arch/x86/kernel/cpu/feat_ctl.c:112:6: warning: no previous prototype for ‘init_ia32_feat_ctl’ [-Wmissing-prototypes] 112 | void init_ia32_feat_ctl(struct cpuinfo_x86 *c)
This warning appeared after commit
5d5103595e9e5 ("x86/cpu: Reinitialize IA32_FEAT_CTL MSR on BSP during wakeup")
had moved the function init_ia32_feat_ctl()'s prototype from arch/x86/kernel/cpu/cpu.h to arch/x86/include/asm/cpu.h.
Note that, before the commit mentioned above, the header include "cpu.h" (arch/x86/kernel/cpu/cpu.h) was added by commit
0e79ad863df43 ("x86/cpu: Fix a -Wmissing-prototypes warning for init_ia32_feat_ctl()")
solely to fix init_ia32_feat_ctl()'s missing prototype. So, the header include "cpu.h" is no longer necessary.

Change that introduced the use of __check_timeout did not account for link types properly, it always assumes ACL_LINK is used thus causing hdev->acl_last_tx to be used even in case of LE_LINK and then again uses ACL_LINK with hci_link_tx_to.
To fix this __check_timeout now takes the link type as parameter and then procedure to use the right last_tx based on the link type and pass it to hci_link_tx_to.

The COUNT_VALUE in the PACKET_CNT register is 16-bit so the maximum value is 65535. Asking the driver to transfer a larger size currently leads to the DMA transfer timing out. Implement ->max_transfer_size() and have the core split the transfer as needed.

ieee80211_tx_queue_params.aifs is not supposed to be written directly to the REG_EDCA_*_PARAM registers. Instead process it like the vendor drivers do. It's kinda hacky but it works.
This change boosts the download speed and makes it more stable.
Tested with RTL8188FU but all the other supported chips should also benefit.

When it returns an error from sctp_auth_asoc_init_active_key(), the active_key is actually not updated. The old sh_key will be freeed while it's still used as active key in asoc. Then an use-after-free will be triggered when sending patckets, as found by syzbot:

This patch is to fix it by not replacing the sh_key when it returns errors from sctp_auth_asoc_init_active_key() in sctp_auth_set_key(). For sctp_auth_set_active_key(), old active_key_id will be set back to asoc->active_key_id when the same thing happens.

[ Upstream commit f4ce91ce12a7c6ead19b128ffa8cff6e3ded2a14 ]
This commit fixes a bug in the tracking of max_packets_out and is_cwnd_limited. This bug can cause the connection to fail to remember that is_cwnd_limited is true, causing the connection to fail to grow cwnd when it should, causing throughput to be lower than it should be.
The following event sequence is an example that triggers the bug:
(a) The connection is cwnd_limited, but packets_out is not at its peak due to TSO deferral deciding not to send another skb yet. In such cases the connection can advance max_packets_seq and set tp->is_cwnd_limited to true and max_packets_out to a small number.
(b) Then later in the round trip the connection is pacing-limited (not cwnd-limited), and packets_out is larger. In such cases the connection would raise max_packets_out to a bigger number but (unexpectedly) flip tp->is_cwnd_limited from true to false.
This commit fixes that bug.
One straightforward fix would be to separately track (a) the next window after max_packets_out reaches a maximum, and (b) the next window after tp->is_cwnd_limited is set to true. But this would require consuming an extra u32 sequence number.
Instead, to save space we track only the most important information. Specifically, we track the strongest available signal of the degree to which the cwnd is fully utilized:
(1) If the connection is cwnd-limited then we remember that fact for the current window.
(2) If the connection not cwnd-limited then we track the maximum number of outstanding packets in the current window.
In particular, note that the new logic cannot trigger the buggy (a)/(b) sequence above because with the new logic a condition where tp->packets_out > tp->max_packets_out can only trigger an update of tp->is_cwnd_limited if tp->is_cwnd_limited is false.
This first showed up in a testing of a BBRv2 dev branch, but this buggy behavior highlighted a general issue with the tcp_cwnd_validate() logic that can cause cwnd to fail to increase at the proper rate for any TCP congestion control, including Reno or CUBIC.

syzbot is reporting lockdep warning at rds_tcp_reset_callbacks() [1], for commit ac3615e7f3cffe2a ("RDS: TCP: Reduce code duplication in rds_tcp_reset_callbacks()") added cancel_delayed_work_sync() into a section protected by lock_sock() without realizing that rds_send_xmit() might call lock_sock().
We don't need to protect cancel_delayed_work_sync() using lock_sock(), for even if rds_{send,recv}_worker() re-queued this work while __flush_work() from cancel_delayed_work_sync() was waiting for this work to complete, retried rds_{send,recv}_worker() is no-op due to the absence of RDS_CONN_UP bit.

[ Upstream commit 62c07983bef9d3e78e71189441e1a470f0d1e653 ]
Christophe Leroy reported a ~80ms latency spike happening at first TCP connect() time.
This is because __inet_hash_connect() uses get_random_once() to populate a perturbation table which became quite big after commit 4c2c8f03a5ab ("tcp: increase source port perturb table to 2^16")
get_random_once() uses DO_ONCE(), which block hard irqs for the duration of the operation.
This patch adds DO_ONCE_SLOW() which uses a mutex instead of a spinlock for operations where we prefer to stay in process context.
Then __inet_hash_connect() can use get_random_slow_once() to populate its perturbation table.

The reference 'child' in the iteration of for_each_available_child_of_node() is only escaped out into a local variable which is only used to check its value. So we still need to the of_node_put() when breaking of the for_each_available_child_of_node() which will automatically increase and decrease the refcount.

Because the PWR_CTRL field is modeled as the power state of the DAC widget, and at the same time it is used to implement mute/unmute, we need some additional book-keeping to have the right end result no matter the sequence of calls. Without this fix, one permanently mutes an ongoing stream by toggling the associated speaker pin control.

Commit 2cc6c717799f ("msi-laptop: Port to new backlight interface selection API") replaced this check:
if (!quirks->old_ec_model || acpi_video_backlight_support()) pr_info("Brightness ignored, ..."); else do_register();
With:
if (quirks->old_ec_model || acpi_video_get_backlight_type() == acpi_backlight_vendor) do_register();
But since the do_register() part was part of the else branch, the entire condition should be inverted. So not only the 2 statements on either side of the || should be inverted, but the || itself should be replaced with a &&.
In practice this has likely not been an issue because the new-ec models (old_ec_model==false) likely all support ACPI video backlight control, making acpi_video_get_backlight_type() return acpi_backlight_video turning the second part of the || also false when old_ec_model == false.

drm_mipi_dbi needs lots of DRM_KMS_HELPER support, so select that Kconfig symbol like it is done is most other uses, and the way that it was before MIPS_DBI was moved from tinydrm to its core location.

The two bridges (stdp2690, stdp4028) do not probe at the same time, so the driver does not call ge_b850v3_resgiter() when probing, causing the driver to try to remove the object that has not been initialized.
Fix this by checking whether both the bridges are probed.

Remove loops over hw_vbif. Instead always VBIF's idx as an index in the array. This fixes an error in dpu_kms_hw_init(), where we fill dpu_kms->hw_vbif[i], but check for an error pointer at dpu_kms->hw_vbif[vbif_idx].

If clk_hw_register() fails, the corresponding clk should not be unregistered.
To handle errors from loops, clean up partial iterations before doing the goto. So add a clk_hw_unregister(). Then use a while (--i >= 0) loop in the unwind section.

[ Upstream commit b73f11e895e140537e7f8c7251211ccd3ce0782b ]
The pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced according to context. We fix it by moving pm_runtime_enable to the endding of mt6660_i2c_probe.

[ Upstream commit 5226c7b9784eee215e3914f440b3c2e1764f67a8 ]
The HDMI driver skips the notification handling from the graphics driver when the codec driver is being in the PM operation. This behavior was introduced by the commit eb399d3c99d8 ("ALSA: hda - Skip ELD notification during PM process"). This skip may cause a problem, as we may miss the ELD update when the connection/disconnection happens right at the runtime-PM operation of the audio codec.
Although this workaround was valid at that time, it's no longer true; the fix was required just because the ELD update procedure needed to wake up the audio codec, which had lead to a runtime-resume during a runtime-suspend. Meanwhile, the ELD update procedure doesn't need a codec wake up any longer since the commit 788d441a164c ("ALSA: hda - Use component ops for i915 HDMI/DP audio jack handling"); i.e. there is no much reason for skipping the notification.
Let's drop those checks for addressing the missing notification.

The break of for_each_available_child_of_node() needs a corresponding of_node_put() when the reference 'child' is not used anymore. Here we do not need to call of_node_put() in fail path as '!match' means no break.
While the of_platform_device_create() will created a new reference by 'child' but it has considered the refcounting.

Commit 327e15428977 ("ARM: dts: kirkwood: consolidate common pinctrl settings") unknowingly broke the serial output on this board. Before this commit, the pinmux was still configured by the bootloader and the kernel didn't reconfigured it again. This was an oversight by the initial board support where the pinmux for the serial line was never configured by the kernel. But with this commit, the serial line will be reconfigured to the wrong pins. This is especially confusing, because the output still works, but the input doesn't. Presumingly, the input is reconfigured to MPP10, but the output is connected to both MPP11 and MPP5.
Override the pinmux in the board device tree.

[ Upstream commit 2254182807fc09ba9dec9a42ef239e373796f1b2 ]
The DMA subsystem could be entirely disabled in Kconfig and then the TEGRA20_APB_DMA option isn't available too. Hence kernel configuration fails if DMADEVICES Kconfig option is disabled due to the unsatisfiable dependency.
The FUSE driver isn't a critical driver and currently it only provides NVMEM interface to userspace which isn't known to be widely used, and thus, it's fine if FUSE driver fails to load.
Let's remove the erroneous Kconfig dependency and let the FUSE driver to fail the probing if DMA is unavailable.

[ Upstream commit 136f4b1ec7c962ee37a787e095fd37b058d72bd3 ]
On arm32, the configuration options to specify the kernel command line type depend on ATAGS. However, the actual CMDLINE cofiguration option does not depend on ATAGS, and the code that handles this is not specific to ATAGS (see drivers/of/fdt.c:early_init_dt_scan_chosen()).
Hence users who desire to override the kernel command line on arm32 must enable support for ATAGS, even on a pure-DT system. Other architectures (arm64, loongarch, microblaze, nios2, powerpc, and riscv) do not impose such a restriction.
Hence drop the dependency on ATAGS.

.read_raw()/.write_raw() could be called asynchronously from user space or other in kernel drivers. Without locking on st->lock these could be called asynchronously while there is a conversion in progress. Read will be harmless but changing registers while conversion is in progress may lead to inconsistent results. Thus, to avoid this lock st->lock.

In case triggered buffers are enabled while system is suspended they will not work anymore after resume. For this call at91_adc_buffer_postdisable() on suspend and at91_adc_buffer_prepare() on resume. On tests it has been seen that at91_adc_buffer_postdisable() call is not necessary but it has been kept because it also does the book keeping for DMA. On resume path there is no need to call at91_adc_configure_touch() as it is embedded in at91_adc_buffer_prepare().

'of_node_put()' can potentially release the memory pointed to by 'iiospec.np' which would leave us with an invalid pointer (and we would still pass it in 'of_xlate()'). Note that it is not guaranteed for the of_node lifespan to be attached to the device (to which is attached) lifespan so that there is (even though very unlikely) the possibility for the node to be freed while the device is still around. Thus, as there are indeed some of_xlate users which do access the node, a race is indeed possible.
As such, we can only release the node after we are done with it.

[ Upstream commit 52c2d15703c3a900d5f78cd599b823db40d5100b ]
The USB "maximum-speed" property can now take the SSP signaling rate generation and lane count with these new strings:
"super-speed-plus-gen2x2" "super-speed-plus-gen2x1" "super-speed-plus-gen1x2"
Introduce usb_get_maximum_ssp_rate() to parse for the corresponding usb_ssp_rate enum. The original usb_get_maximum_speed() will return USB_SPEED_SUPER_PLUS if it matches one of these new strings.

After completion of data transfer of one or multiple descriptors, the completion status and the current head pointer to submission queue are written into the CQ and interrupt can be generated to inform the software. In interrupt process CQ is read and cq_head is updated.
hisi_dma_irq updates cq_head only when the completion status is success. When an abnormal interrupt reports, cq_head will not update which will cause subsequent interrupt processes read the error CQ and never report the correct status.

[ Upstream commit 2cbb95883c990d0002a77e13d3278913ab26ad79 ]
When we get a DMA channel and try to use it in multiple threads it will cause oops and hanging the system.

This occurs because the transmission timed out, and that's due to data race. Each thread rewrite channels's descriptor as soon as device_issue_pending is called. It leads to the situation that the driver thinks that it uses the right descriptor in interrupt handler while channels's descriptor has been changed by other thread. The descriptor which in fact reported interrupt will not be handled any more, as well as its tx->callback. That's why timeout reports.
With current fixes channels' descriptor changes it's value only when it has been used. A new descriptor is acquired from vc->desc_issued queue that is already filled with descriptors that are ready to be sent. Threads have no direct access to DMA channel descriptor. In case of channel's descriptor is busy, try to submit to HW again when a descriptor is completed. In this case, vc->desc_issued may be empty when hisi_dma_start_transfer is called, so delete error reporting on this. Now it is just possible to queue a descriptor for further processing.

In https://lore.kernel.org/lkml/20211209150910.GA23668@axis.com/
Vincent's patch commented on, and worked around, a bug toggling static_branch's, when a 2nd PRINTK-ish flag was added. The bug results in a premature static_branch_disable when the 1st of 2 flags was disabled.
The cited commit computed newflags, but then in the JUMP_LABEL block, failed to use that result, instead using just one of the terms in it. Using newflags instead made the code work properly.
This is Vincents test-case, reduced. It needs the 2nd flag to demonstrate the bug, but it's explanatory here.

[ Upstream commit 85d6b66d31c35158364058ee98fb69ab5bb6a6b1 ]
For CONFIG_DYNAMIC_DEBUG=N, the ddebug_dyndbg_module_param_cb() stub-fn is too permissive:
bash-5.1# modprobe drm JUNKdyndbg bash-5.1# modprobe drm dyndbgJUNK [ 42.933220] dyndbg param is supported only in CONFIG_DYNAMIC_DEBUG builds [ 42.937484] ACPI: bus type drm_connector registered
This caused no ill effects, because unknown parameters are either ignored by default with an "unknown parameter" warning, or ignored because dyndbg allows its no-effect use on non-dyndbg builds.
But since the code has an explicit feedback message, it should be issued accurately. Fix with strcmp for exact param-name match.

--------------------------------
[ Upstream commit e75ef56f74965f426dd819a41336b640ffdd8fbc ]
dyndbg's control-parser: ddebug_parse_query(), requires that search terms: module, func, file, lineno, are used only once in a query; a thing cannot be named both foo and bar.
The cited commit added an overriding module modname, taken from the module loader, which is authoritative. So it set query.module 1st, which disallowed its use in the query-string.
But now, its useful to allow a module-load to enable classes across a whole (or part of) a subsystem at once.
# enable (dynamic-debug in) drm only modprobe drm dyndbg="class DRM_UT_CORE +p"
# get drm_helper too modprobe drm dyndbg="class DRM_UT_CORE module drm* +p"
# get everything that knows DRM_UT_CORE modprobe drm dyndbg="class DRM_UT_CORE module * +p"
# also for boot-args: drm.dyndbg="class DRM_UT_CORE module * +p"
So convert the override into a default, by filling it only when/after the query-string omitted the module.
NB: the query class FOO handling is forthcoming.

Commit f6424c22aa36 ("mtd: rawnand: fsl_elbc: Make SW ECC work") added support for specifying ECC mode via DTS and skipping autodetection.
But it broke explicit specification of HW ECC mode in DTS as correct settings for HW ECC mode are applied only when NONE mode or nothing was specified in DTS file.
Also it started aliasing NONE mode to be same as when ECC mode was not specified and disallowed usage of ON_DIE mode.
Fix all these issues. Use autodetection of ECC mode only in case when mode was really not specified in DTS file by checking that ecc value is invalid. Set HW ECC settings either when HW ECC was specified in DTS or it was autodetected. And do not fail when ON_DIE mode is set.

For header and trailer/padding processing, siw did not consume new skb data until minimum amount present to fill current header or trailer structure, including potential payload padding. Not consuming any data during upcall may cause a receive stall, since tcp_read_sock() is not upcalling again if no new data arrive. A NFSoRDMA client got stuck at RDMA Write reception of unaligned payload, if the current skb did contain only the expected 3 padding bytes, but not the 4 bytes CRC trailer. Expecting 4 more bytes already arrived in another skb, and not consuming those 3 bytes in the current upcall left the Write incomplete, waiting for the CRC forever.

[ Upstream commit 690aa8c3ae308bc696ec8b1b357b995193927083 ]
ACS-5 section 7.13.6.41 Words 85..87, 120: Commands and feature sets supported or enabled states that:
If bit 15 of word 86 is set to one, bit 14 of word 119 is set to one, and bit 15 of word 119 is cleared to zero, then word 119 is valid.
If bit 15 of word 86 is set to one, bit 14 of word 120 is set to one, and bit 15 of word 120 is cleared to zero, then word 120 is valid.
(This text also exists in really old ACS standards, e.g. ACS-3.)
Currently, ata_id_sense_reporting_enabled() and ata_id_has_sense_reporting() both check bit 15 of word 86, but neither of them check that bit 14 of word 119 is set to one, or that bit 15 of word 119 is cleared to zero.
Additionally, make ata_id_sense_reporting_enabled() return false if !ata_id_has_sense_reporting(), similar to how e.g. ata_id_flush_ext_enabled() returns false if !ata_id_has_flush_ext().

(This text also exists in really old ACS standards, e.g. ACS-3.)
The problem with ata_id_has_dipm() is that the while it performs a check against 0 and 0xffff, it performs the check against ATA_ID_FEATURE_SUPP (word 78), the same word where the feature bit is stored.
Fix this by performing the check against ATA_ID_SATA_CAPABILITY (word 76), like required by the spec. The feature bit check itself is of course still performed against ATA_ID_FEATURE_SUPP (word 78).
Additionally, move the macro to the other ATA_ID_FEATURE_SUPP macros (which already have this check), thus making it more likely that the next ATA_ID_FEATURE_SUPP macro that is added will include this check.

Current code produces a warning as shown below when total characters in the constituent block device names plus the slashes exceeds 200. snprintf() returns the number of characters generated from the given input, which could cause the expression “200 – len” to wrap around to a large positive number. Fix this by using scnprintf() instead, which returns the actual number of characters written into the buffer.

[ Upstream commit e2eed85bc75138a9eeb63863d20f8904ac42a577 ]
When doing degrade/recover tests using the journal a kernel BUG is hit at drivers/md/raid5.c:4381 in handle_parity_checks5():
BUG_ON(!test_bit(R5_UPTODATE, &dev->flags));
This was found to occur because handle_stripe_fill() was skipped for stripes in the journal due to a condition in that function. Thus blocks were not fetched and R5_UPTODATE was not set when the code reached handle_parity_checks5().
To fix this, don't skip handle_stripe_fill() unless the stripe is for read.

Set 'iova' and 'length' on ib_mr in ib_uverbs and ib_core layers to let all drivers have the members filled. Also, this commit removes redundancy in the respective drivers.
Previously, commit 04c0a5fcfcf65 ("IB/uverbs: Set IOVA on IB MR in uverbs layer") changed to set 'iova', but seems to have missed 'length' and the ib_core layer at that time.

commit 8b328f8002bc ("xhci: re-initialize the HC during resume if HCE was set") introduced a new warning message when the host controller error was set and re-initializing.
This is expected behavior on some designs which already set `xhci->broken_suspend` so the new warning is alarming to some users.
Modify the code to only show the warning if this was a surprising behavior to the XHCI driver.

[ Upstream commit 24b7ba2f88e04800b54d462f376512e8c41b8a3c ]
When opts->pnp_string is changed with configfs, new memory is allocated for the string. It does not, however, update dev->pnp_string, even though the memory is freed. When rquesting the string, the host then gets old or corrupted data rather than the new string. The ieee 1284 id string should be allowed to change while the device is connected.
The bug was introduced in commit fdc01cc286be ("usb: gadget: printer: Remove pnp_string static buffer"), which changed opts->pnp_string from a char[] to a char*. This patch changes dev->pnp_string from a char* to a char** pointing to opts->pnp_string.

[ Upstream commit 039d4926379b1d1c17b51cf21c500a5eed86899e ]
Invoking TIOCVHANGUP on 8250_mid port on Ice Lake-D and then reopening the port triggers these faults during serial8250_do_startup():
DMAR: DRHD: handling fault status reg 3 DMAR: [DMA Write NO_PASID] Request device [00:1a.0] fault addr 0x0 [fault reason 0x05] PTE Write access is not set
If the IRQ hasn't been set up yet, the UART will have zeroes in its MSI address/data registers. Disabling the IRQ at the interrupt controller won't stop the UART from performing a DMA write to the address programmed in its MSI address register (zero) when it wants to signal an interrupt.
The UARTs (in Ice Lake-D) implement PCI 2.1 style MSI without masking capability, so there is no way to mask the interrupt at the source PCI function level, except disabling the MSI capability entirely, but that would cause it to fall back to INTx# assertion, and the PCI specification prohibits disabling the MSI capability as a way to mask a function's interrupt service request.
The MSI address register is zeroed by the hangup as the irq is freed. The interrupt is signalled during serial8250_do_startup() performing a THRE test that temporarily toggles THRI in IER. The THRE test currently occurs before UART's irq (and MSI address) is properly set up.
Refactor serial8250_do_startup() such that irq is set up before the THRE test. The current irq setup code is intermixed with the timer setup code. As THRE test must be performed prior to the timer setup, extract it into own function and call it only after the THRE test.
The ->setup_timer() needs to be part of the struct uart_8250_ops in order to not create circular dependency between 8250 and 8250_base modules.

[ Upstream commit 316ae95c175a7d770d1bfe4c011192712f57aa4a ]
lpuart_dma_shutdown tears down lpuart dma, but lpuart_flush_buffer can still occur which in turn tries to access dma apis if lpuart_dma_tx_use flag is true. At this point since dma is torn down, these dma apis can abort. Set lpuart_dma_tx_use and the corresponding rx flag lpuart_dma_rx_use to false in lpuart_dma_shutdown so that dmas are not accessed after they are relinquished.
Otherwise, when try to kill btattach, kernel may panic. This patch may fix this issue. root@imx8ulpevk:~# btattach -B /dev/ttyLP2 -S 115200 ^C[ 90.182296] Internal error: synchronous external abort: 96000210 [#1] PREEMPT SMP [ 90.189806] Modules linked in: moal(O) mlan(O) [ 90.194258] CPU: 0 PID: 503 Comm: btattach Tainted: G O 5.15.32-06136-g34eecdf2f9e4 #37 [ 90.203554] Hardware name: NXP i.MX8ULP 9X9 EVK (DT) [ 90.208513] pstate: 600000c5 (nZCv daIF -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 90.215470] pc : fsl_edma3_disable_request+0x8/0x60 [ 90.220358] lr : fsl_edma3_terminate_all+0x34/0x20c [ 90.225237] sp : ffff800013f0bac0 [ 90.228548] x29: ffff800013f0bac0 x28: 0000000000000001 x27: ffff000008404800 [ 90.235681] x26: ffff000008404960 x25: ffff000008404a08 x24: ffff000008404a00 [ 90.242813] x23: ffff000008404a60 x22: 0000000000000002 x21: 0000000000000000 [ 90.249946] x20: ffff800013f0baf8 x19: ffff00000559c800 x18: 0000000000000000 [ 90.257078] x17: 0000000000000000 x16: 0000000000000000 x15: 0000000000000000 [ 90.264211] x14: 0000000000000003 x13: 0000000000000000 x12: 0000000000000040 [ 90.271344] x11: ffff00000600c248 x10: ffff800013f0bb10 x9 : ffff000057bcb090 [ 90.278477] x8 : fffffc0000241a08 x7 : ffff00000534ee00 x6 : ffff000008404804 [ 90.285609] x5 : 0000000000000000 x4 : 0000000000000000 x3 : ffff0000055b3480 [ 90.292742] x2 : ffff8000135c0000 x1 : ffff00000534ee00 x0 : ffff00000559c800 [ 90.299876] Call trace: [ 90.302321] fsl_edma3_disable_request+0x8/0x60 [ 90.306851] lpuart_flush_buffer+0x40/0x160 [ 90.311037] uart_flush_buffer+0x88/0x120 [ 90.315050] tty_driver_flush_buffer+0x20/0x30 [ 90.319496] hci_uart_flush+0x44/0x90 [ 90.323162] +0x34/0x12c [ 90.327253] tty_ldisc_close+0x38/0x70 [ 90.331005] tty_ldisc_release+0xa8/0x190 [ 90.335018] tty_release_struct+0x24/0x8c [ 90.339022] tty_release+0x3ec/0x4c0 [ 90.342593] __fput+0x70/0x234 [ 90.345652] ____fput+0x14/0x20 [ 90.348790] task_work_run+0x84/0x17c [ 90.352455] do_exit+0x310/0x96c [ 90.355688] do_group_exit+0x3c/0xa0 [ 90.359259] __arm64_sys_exit_group+0x1c/0x20 [ 90.363609] invoke_syscall+0x48/0x114 [ 90.367362] el0_svc_common.constprop.0+0xd4/0xfc [ 90.372068] do_el0_svc+0x2c/0x94 [ 90.375379] el0_svc+0x28/0x80 [ 90.378438] el0t_64_sync_handler+0xa8/0x130 [ 90.382711] el0t_64_sync+0x1a0/0x1a4 [ 90.386376] Code: 17ffffda d503201f d503233f f9409802 (b9400041) [ 90.392467] ---[ end trace 2f60524b4a43f1f6 ]--- [ 90.397073] note: btattach[503] exited with preempt_count 1 [ 90.402636] Fixing recursive fault but reboot is needed!

[ Upstream commit 2a2db520e3ca5aafba7c211abfd397666c9b5f9d ]
In some initialization functions of this driver, memory is allocated with 'i' acting as an index variable and increasing from 0. The commit in "Fixes" introduces some clean-up codes in case of allocation failure, which free memory in reverse order with 'i' decreasing to 0. However, there are some problems: - The case i=0 is left out. Thus memory is leaked. - In case memory allocation fails right from the start, the memory freeing loops will start with i=-1 and invalid memory locations will be accessed.
One of these loops has been fixed in commit c8ff91535880 ("staging: vt6655: fix potential memory leak"). Fix the remaining erroneous loops.

[ Upstream commit 3e081438b8e639cc76ef1a5ce0c1bd8a154082c7 ]
Currently the gsmi driver registers a panic notifier as well as reboot and die notifiers. The callbacks registered are called in atomic and very limited context - for instance, panic disables preemption and local IRQs, also all secondary CPUs (not executing the panic path) are shutdown.
With that said, taking a spinlock in this scenario is a dangerous invitation for lockup scenarios. So, fix that by checking if the spinlock is free to acquire in the panic notifier callback - if not, bail-out and avoid a potential hang.

Since commit 027b57170bf8 ("serial: core: Fix initializing and restoring termios speed") termios speed is available also in struct console.
So properly restore also c_ispeed and c_ospeed members after suspend to fix restoring termios speed which is not represented by Bnnn constant.

[ Upstream commit 46ba53c30666717cb06c2b3c5d896301cd00d0c0 ]
When executing SMP task failed, the smp_execute_task_sg() calls del_timer() to delete "slow_task->timer". However, if the timer handler sas_task_internal_timedout() is running, the del_timer() in smp_execute_task_sg() will not stop it and a UAF will happen. The process is shown below:
(thread 1) | (thread 2) smp_execute_task_sg() | sas_task_internal_timedout() ... | del_timer() | ... | ... sas_free_task(task) | kfree(task->slow_task) //FREE| | task->slow_task->... //USE
Fix by calling del_timer_sync() in smp_execute_task_sg(), which makes sure the timer handler have finished before the "task->slow_task" is deallocated.

[ Upstream commit 57569c37f0add1b6489e1a1563c71519daf732cf ]
Fix a NULL pointer crash that occurs when we are freeing the socket at the same time we access it via sysfs.
The problem is that:
1. iscsi_sw_tcp_conn_get_param() and iscsi_sw_tcp_host_get_param() take the frwd_lock and do sock_hold() then drop the frwd_lock. sock_hold() does a get on the "struct sock".
2. iscsi_sw_tcp_release_conn() does sockfd_put() which does the last put on the "struct socket" and that does __sock_release() which sets the sock->ops to NULL.
3. iscsi_sw_tcp_conn_get_param() and iscsi_sw_tcp_host_get_param() then call kernel_getpeername() which accesses the NULL sock->ops.
Above we do a get on the "struct sock", but we needed a get on the "struct socket". Originally, we just held the frwd_lock the entire time but in commit bcf3a2953d36 ("scsi: iscsi: iscsi_tcp: Avoid holding spinlock while calling getpeername()") we switched to refcount based because the network layer changed and started taking a mutex in that path, so we could no longer hold the frwd_lock.
Instead of trying to maintain multiple refcounts, this just has us use a mutex for accessing the socket in the interface code paths.

While fixing up the driver I noticed that my IPQ8074 board was hanging after CPUFreq switched the frequency during boot, WDT would eventually reset it.
So mark apcs_alias0_core_clk as critical since its the clock feeding the CPU cluster and must never be disabled.

User reports observing timer event report channel halted but no error observed in CHANERR register. The driver finished self-test and released channel resources. Debug shows that __cleanup() can call mod_timer() after the timer has been deleted and thus resurrect the timer. While harmless, it causes suprious error message to be emitted. Use mod_timer_pending() call to prevent deleted timer from being resurrected.

[ Upstream commit c388cc804016cf0f65afdc2362b120aa594ff3e6 ]
We have discovered random glitches during the system boot up procedure. The problem investigation led us to the weird outcomes: when none of the Renesas 5P49V6901 ports are explicitly enabled by the kernel driver, the glitches disappeared. It was a mystery since the SoC external clock domains were fed with different 5P49V6901 outputs. The driver code didn't seem like bogus either. We almost despaired to find out a root cause when the solution has been found for a more modern revision of the chip. It turned out the 5P49V6901 clock generator stopped its output for a short period of time during the VC5_OUT_DIV_CONTROL register writing. The same problem was found for the 5P49V6965 revision of the chip and was successfully fixed in commit fc336ae622df ("clk: vc5: fix output disabling when enabling a FOD") by enabling the "bypass_sync" flag hidden inside "Unused Factory Reserved Register". Even though the 5P49V6901 registers description and programming guide doesn't provide any intel regarding that flag, setting it up anyway in the officially unused register completely eliminated the denoted glitches. Thus let's activate the functionality submitted in commit fc336ae622df ("clk: vc5: fix output disabling when enabling a FOD") for the Renesas 5P49V6901 chip too in order to remove the ports implicit inter-dependency.

Baikal-T1 CCU reference manual says that both xGMAC reference and xGMAC PTP clocks are generated by two different wrappers with the same constant divider thus each producing a 156.25 MHz signal. But for some reason both of these clock sources are gated by a single switch-flag in the CCU registers space - CCU_SYS_XGMAC_BASE.BIT(0). In order to make the clocks handled independently we need to define a shared parental gate so the base clock signal would be switched off only if both of the child-clocks are disabled.
Note the ID is intentionally set to -2 since we are going to add a one more internal clock identifier in the next commit.

[ Upstream commit 081a9b7c74eae4e12b2cb1b86720f836a8f29247 ]
It turns out the internal SATA reference clock signal will stay unavailable for the SATA interface consumer until the buffer on it's way is ungated. So aside with having the actual clock divider enabled we need to ungate a buffer placed on the signal way to the SATA controller (most likely some rudiment from the initial SoC release). Seeing the switch flag is placed in the same register as the SATA-ref clock divider at a non-standard ffset, let's implement it as a separate clock controller with the set-rate propagation to the parental clock divider wrapper. As such we'll be able to disable/enable and still change the original clock source rate.

When building with a recent version of clang, there are a couple of errors around the call to module_init():
arch/powerpc/math-emu/math_efp.c:927:1: error: type specifier missing, defaults to 'int'; ISO C99 and later do not support implicit int [-Wimplicit-int] module_init(spe_mathemu_init); ^ int arch/powerpc/math-emu/math_efp.c:927:13: error: a parameter list without types is only allowed in a function definition module_init(spe_mathemu_init); ^ 2 errors generated.
module_init() is a macro, which is not getting expanded because module.h is not included in this file. Add the include so that the macro can expand properly, clearing up the build failure.

Section 1.9 of TLFS v6.0b says:
"All structures are padded in such a way that fields are aligned naturally (that is, an 8-byte field is aligned to an offset of 8 bytes and so on)".
'struct enlightened_vmcs' has a glitch:
... struct { u32 nested_flush_hypercall:1; /* 836: 0 4 */ u32 msr_bitmap:1; /* 836: 1 4 */ u32 reserved:30; /* 836: 2 4 */ } hv_enlightenments_control; /* 836 4 */ u32 hv_vp_id; /* 840 4 */ u64 hv_vm_id; /* 844 8 */ u64 partition_assist_page; /* 852 8 */ ...
And the observed values in 'partition_assist_page' make no sense at all. Fix the layout by padding the structure properly.

[ Upstream commit 37b9345ce7f4ab17538ea62def6f6d430f091355 ]
Commit 2eb28006431c ("powerpc/e500v2: Add Power ISA properties to comply with ePAPR 1.1") introduced new include file e500v2_power_isa.dtsi and should have used it for all e500v2 platforms. But apparently it was used also for e500v1 platforms mpc8540, mpc8541, mpc8555 and mpc8560.
e500v1 cores compared to e500v2 do not support double precision floating point SPE instructions. Hence power-isa-sp.fd should not be set on e500v1 platforms, which is in e500v2_power_isa.dtsi include file.
Fix this issue by introducing a new e500v1_power_isa.dtsi include file and use it in all e500v1 device tree files.

There are two issues here:
1) The "len" variable needs to be checked before the very first write. Otherwise if omap2_iommu_dump_ctx() with "bytes" less than 32 it is a buffer overflow. 2) The snprintf() function returns the number of bytes that *would* have been copied if there were enough space. But we want to know the number of bytes which were *actually* copied so use scnprintf() instead.

[ Upstream commit bc155c6c188c2f0c5749993b1405673d25a80389 ]
Changes from v1: * removed the default implementation from set_pub_key: it is assumed that an implementation must always have this callback defined as there are no use case for an algorithm, which doesn't need a public key
Many akcipher implementations (like ECDSA) support only signature verifications, so they don't have all callbacks defined.
Commit 78a0324f4a53 ("crypto: akcipher - default implementations for request callbacks") introduced default callbacks for sign/verify operations, which just return an error code.
However, these are not enough, because before calling sign the caller would likely call set_priv_key first on the instantiated transform (as the in-kernel testmgr does). This function does not have a default stub, so the kernel crashes, when trying to set a private key on an akcipher, which doesn't support signature generation.
I've noticed this, when trying to add a KAT vector for ECDSA signature to the testmgr.
With this patch the testmgr returns an error in dmesg (as it should) instead of crashing the kernel NULL ptr dereference.

[ Upstream commit e0831e7af4e03f2715de102e18e9179ec0a81562 ]
In order to do DMAs, the QAT device requires that the scatterlist structures are mapped and translated into a format that the firmware can understand. This is defined as the composition of a scatter gather list (SGL) descriptor header, the struct qat_alg_buf_list, plus a variable number of flat buffer descriptors, the struct qat_alg_buf.
The allocation and mapping of these data structures is done each time a request is received from the skcipher and aead APIs. In an OOM situation, this behaviour might lead to a dead-lock if an allocation fails.
Based on the conversation in [1], increase the size of the aead and skcipher request contexts to include an SGL descriptor that can handle a maximum of 4 flat buffers. If requests exceed 4 entries buffers, memory is allocated dynamically.

[ Upstream commit cf5bb835b7c8a5fee7f26455099cca7feb57f5e9 ]
When CONFIG_DMA_API_DEBUG is selected, while running the crypto self test on the QAT crypto algorithms, the function add_dma_entry() reports a warning similar to the one below, saying that overlapping mappings are not supported. This occurs in tests where the input and the output scatter list point to the same buffers (i.e. two different scatter lists which point to the same chunks of memory).
The logic that implements the mapping uses the flag DMA_BIDIRECTIONAL for both the input and the output scatter lists which leads to overlapped write mappings. These are not supported by the DMA layer.
Fix by specifying the correct DMA transfer directions when mapping buffers. For in-place operations where the input scatter list matches the output scatter list, buffers are mapped once with DMA_BIDIRECTIONAL, otherwise input buffers are mapped using the flag DMA_TO_DEVICE and output buffers are mapped with DMA_FROM_DEVICE. Overlapping a read mapping with a write mapping is a valid case in dma-coherent devices like QAT. The function that frees and unmaps the buffers, qat_alg_free_bufl() has been changed accordingly to the changes to the mapping function.

IOMMU_IOVA is intended to be an optional library for users to select as and when they desire. Since it can be a module now, this means that built-in code which has chosen not to select it should not fail to link if it happens to have selected as a module by someone else. Replace IS_ENABLED() with IS_REACHABLE() to do the right thing.

[ Upstream commit a7f3257da8a86b96fb9bf1bba40ae0bbd7f1885a ]
When receiving some signal, GNU Make automatically deletes the target if it has already been changed by the interrupted recipe.
If the target is possibly incomplete due to interruption, it must be deleted so that it will be remade from scratch on the next run of make. Otherwise, the target would remain corrupted permanently because its timestamp had already been updated.
Thanks to this behavior of Make, you can stop the build any time by pressing Ctrl-C, and just run 'make' to resume it.
Kbuild also relies on this feature, but it is equivalently important for any build systems that make decisions based on timestamps (if you want to support Ctrl-C reliably).
However, this does not always work as claimed; Make immediately dies with Ctrl-C if its stderr goes into a pipe.
[Test Makefile]
foo: echo hello > $@ sleep 3 echo world >> $@
[Test Result]
$ make # hit Ctrl-C echo hello > foo sleep 3 ^Cmake: *** Deleting file 'foo' make: *** [Makefile:3: foo] Interrupt
$ make 2>&1 | cat # hit Ctrl-C echo hello > foo sleep 3 ^C$ # 'foo' is often left-over
The reason is because SIGINT is sent to the entire process group. In this example, SIGINT kills 'cat', and 'make' writes the message to the closed pipe, then dies with SIGPIPE before cleaning the target.
A typical bad scenario (as reported by [1], [2]) is to save build log by using the 'tee' command:
$ make 2>&1 | tee log
This can be problematic for any build systems based on Make, so I hope it will be fixed in GNU Make. The maintainer of GNU Make stated this is a long-standing issue and difficult to fix [3]. It has not been fixed yet as of writing.
So, we cannot rely on Make cleaning the target. We can do it by ourselves, in signal traps.
As far as I understand, Make takes care of SIGHUP, SIGINT, SIGQUIT, and SITERM for the target removal. I added the traps for them, and also for SIGPIPE just in case cmd_* rule prints something to stdout or stderr (but I did not observe an actual case where SIGPIPE was triggered).
[Note 1]
The trap handler might be worth explaining.
rm -f $@; trap - $(sig); kill -s $(sig) $$
This lets the shell kill itself by the signal it caught, so the parent process can tell the child has exited on the signal. Generally, this is a proper manner for handling signals, in case the calling program (like Bash) may monitor WIFSIGNALED() and WTERMSIG() for WCE although this may not be a big deal here because GNU Make handles SIGHUP, SIGINT, SIGQUIT in WUE and SIGTERM in IUE.
IUE - Immediate Unconditional Exit WUE - Wait and Unconditional Exit WCE - Wait and Cooperative Exit
For details, see "Proper handling of SIGINT/SIGQUIT" [4].
[Note 2]
Reverting 392885ee82d3 ("kbuild: let fixdep directly write to .*.cmd files") would directly address [1], but it only saves if_changed_dep. As reported in [2], all commands that use redirection can potentially leave an empty (i.e. broken) target.
[Note 3]
Another (even safer) approach might be to always write to a temporary file, and rename it to $@ at the end of the recipe.
<command> > $(tmp-target) mv $(tmp-target) $@
It would require a lot of Makefile changes, and result in ugly code, so I did not take it.
[Note 4]
A little more thoughts about a pattern rule with multiple targets (or a grouped target).
%.x %.y: %.z <recipe>
When interrupted, GNU Make deletes both %.x and %.y, while this solution only deletes $@. Probably, this is not a big deal. The next run of make will execute the rule again to create $@ along with the other files.

If an error is detected as a result of user-space process accessing a corrupt memory location, the CPU may take an abort. Then the platform firmware reports kernel via NMI like notifications, e.g. NOTIFY_SEA, NOTIFY_SOFTWARE_DELEGATED, etc.
For NMI like notifications, commit 7f17b4a121d0 ("ACPI: APEI: Kick the memory_failure() queue for synchronous errors") keep track of whether memory_failure() work was queued, and make task_work pending to flush out the queue so that the work is processed before return to user-space.
The code use init_mm to check whether the error occurs in user space:
if (current->mm != &init_mm)
The condition is always true, becase _nobody_ ever has "init_mm" as a real VM any more.
In addition to abort, errors can also be signaled as asynchronous exceptions, such as interrupt and SError. In such case, the interrupted current process could be any kind of thread. When a kernel thread is interrupted, the work ghes_kick_task_work deferred to task_work will never be processed because entry_handler returns to call ret_to_kernel() instead of ret_to_user(). Consequently, the estatus_node alloced from ghes_estatus_pool in ghes_in_nmi_queue_one_entry() will not be freed. After around 200 allocations in our platform, the ghes_estatus_pool will run of memory and ghes_in_nmi_queue_one_entry() returns ENOMEM. As a result, the event failed to be processed.
sdei: event 805 on CPU 113 failed with error: -2
Finally, a lot of unhandled events may cause platform firmware to exceed some threshold and reboot.
The condition should generally just do
if (current->mm)
as described in active_mm.rst documentation.
Then if an asynchronous error is detected when a kernel thread is running, (e.g. when detected by a background scrubber), do not add task_work to it as the original patch intends to do.

In this case, the "FI_NO_EXTENT" flag is set between f2fs_update_extent_tree_range and is_inode_flag_set by other process. it leads to clearing the whole exten tree which should not have happened. And we fix it by move the setting it to the range of write_lock.

[ Upstream commit 493720a4854343b7c3fe100cda6a3a2c3f8d4b5d ]
Lei Li reported a issue: if foreground operations are frequent, background checkpoint may be always skipped due to below check, result in losing more data after sudden power-cut.
f2fs_balance_fs_bg() ... if (!is_idle(sbi, REQ_TIME) && (!excess_dirty_nats(sbi) && !excess_dirty_nodes(sbi))) return;
E.g: cp_interval = 5 second idle_interval = 2 second foreground operation interval = 1 second (append 1 byte per second into file)
In such case, no matter when it calls f2fs_balance_fs_bg(), is_idle(, REQ_TIME) returns false, result in skipping background checkpoint.
This patch changes as below to make trigger condition being more reasonable: - trigger sync_fs() if dirty_{nats,nodes} and prefree segs exceeds threshold; - skip triggering sync_fs() if there is any background inflight IO or there is foreground operation recently and meanwhile cp_rwsem is being held by someone;

[ Upstream commit d80afefb17e01aa0c46a8eebc01882e0ebd8b0f6 ]
f2fs_inode_info.cp_task was introduced for FS_CP_DATA_IO accounting since commit b0af6d491a6b ("f2fs: add app/fs io stat").
However, cp_task usage coverage has been increased due to below commits: commit 040d2bb318d1 ("f2fs: fix to avoid deadloop if data_flush is on") commit 186857c5a14a ("f2fs: fix potential recursive call when enabling data_flush")
So that, if data_flush mountoption is on, when data flush was triggered from background, the IO from data flush will be accounted as checkpoint IO type incorrectly.
In order to fix this issue, this patch splits cp_task into two: a) cp_task: used for IO accounting b) wb_task: used to avoid deadlock

[ Upstream commit 093590c16b447f53e66771c8579ae66c96f6ef61 ]
The fill_page_cache_func() function allocates couple of pages to store kvfree_rcu_bulk_data structures. This is a lightweight (GFP_NORETRY) allocation which can fail under memory pressure. The function will, however keep retrying even when the previous attempt has failed.
This retrying is in theory correct, but in practice the allocation is invoked from workqueue context, which means that if the memory reclaim gets stuck, these retries can hog the worker for quite some time. Although the workqueues subsystem automatically adjusts concurrency, such adjustment is not guaranteed to happen until the worker context sleeps. And the fill_page_cache_func() function's retry loop is not guaranteed to sleep (see the should_reclaim_retry() function).
And we have seen this function cause workqueue lockups:
kernel: BUG: workqueue lockup - pool cpus=93 node=1 flags=0x1 nice=0 stuck for 32s! [...] kernel: pool 74: cpus=37 node=0 flags=0x1 nice=0 hung=32s workers=2 manager: 2146 kernel: pwq 498: cpus=249 node=1 flags=0x1 nice=0 active=4/256 refcnt=5 kernel: in-flight: 1917:fill_page_cache_func kernel: pending: dbs_work_handler, free_work, kfree_rcu_monitor
Originally, we thought that the root cause of this lockup was several retries with direct reclaim, but this is not yet confirmed. Furthermore, we have seen similar lockups without any heavy memory pressure. This suggests that there are other factors contributing to these lockups. However, it is not really clear that endless retries are desireable.
So let's make the fill_page_cache_func() function back off after allocation failure.

Kernels built with CONFIG_PROVE_RCU=y and CONFIG_DEBUG_LOCK_ALLOC=y attempt to emit a warning when the synchronize_rcu_tasks_generic() function is called during early boot while the rcu_scheduler_active variable is RCU_SCHEDULER_INACTIVE. However the warnings is not actually be printed because the debug_lockdep_rcu_enabled() returns false, exactly because the rcu_scheduler_active variable is still equal to RCU_SCHEDULER_INACTIVE.
This commit therefore replaces RCU_LOCKDEP_WARN() with WARN_ONCE() to force these warnings to actually be printed.

Toshiba Satellite Z830 needs the quirk video_disable_backlight_sysfs_if for proper backlight control after suspend/resume cycles.
Toshiba Portege Z830 is simply the same laptop rebranded for certain markets (I looked through the manual to other language sections to confirm this) and thus also needs this quirk.
Thanks to Hans de Goede for suggesting this fix.

Clang is especially sensitive about argument type matching when using __overloaded functions (like memcmp(), etc). Help it see that function pointers are just "void *". Avoids this error:

When CPU 0 is offline and intel_powerclamp is used to inject idle, it generates kernel BUG:
BUG: using smp_processor_id() in preemptible [00000000] code: bash/15687 caller is debug_smp_processor_id+0x17/0x20 CPU: 4 PID: 15687 Comm: bash Not tainted 5.19.0-rc7+ #57 Call Trace: <TASK> dump_stack_lvl+0x49/0x63 dump_stack+0x10/0x16 check_preemption_disabled+0xdd/0xe0 debug_smp_processor_id+0x17/0x20 powerclamp_set_cur_state+0x7f/0xf9 [intel_powerclamp] ... ...
Here CPU 0 is the control CPU by default and changed to the current CPU, if CPU 0 offlined. This check has to be performed under cpus_read_lock(), hence the above warning.
Use get_cpu() instead of smp_processor_id() to avoid this BUG.

[ Upstream commit 3e1730842f142add55dc658929221521a9ea62b6 ]
Clang produces a false positive when building with CONFIG_FORTIFY_SOURCE=y and CONFIG_UBSAN_BOUNDS=y when operating on an array with a dynamic offset. Work around this by using a direct assignment of an empty instance. Avoids this warning:
../include/linux/fortify-string.h:309:4: warning: call to __write_overflow_field declared with 'warn ing' attribute: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Wat tribute-warning] __write_overflow_field(p_size_field, size); ^
which was isolated to the memset() call in xen_load_idt().
Note that this looks very much like another bug that was worked around: https://github.com/ClangBuiltLinux/linux/issues/1592

[ Upstream commit 019805fea91599b22dfa62ffb29c022f35abeb06 ]
Use-after-free occurred when the laundromat tried to free expired cpntf_state entry on the s2s_cp_stateids list after inter-server copy completed. The sc_cp_list that the expired copy state was inserted on was already freed.
When COPY completes, the Linux client normally sends LOCKU(lock_state x), FREE_STATEID(lock_state x) and CLOSE(open_state y) to the source server. The nfs4_put_stid call from nfsd4_free_stateid cleans up the copy state from the s2s_cp_stateids list before freeing the lock state's stid.
However, sometimes the CLOSE was sent before the FREE_STATEID request. When this happens, the nfsd4_close_open_stateid call from nfsd4_close frees all lock states on its st_locks list without cleaning up the copy state on the sc_cp_list list. When the time the FREE_STATEID arrives the server returns BAD_STATEID since the lock state was freed. This causes the use-after-free error to occur when the laundromat tries to free the expired cpntf_state.
This patch adds a call to nfs4_free_cpntf_statelist in nfsd4_close_open_stateid to clean up the copy state before calling free_ol_stateid_reaplist to free the lock state's stid on the reaplist.

[ Upstream commit cea558855c39b7f1f02ff50dcf701ca6596bc964 ]
When bpftool is linked against libcap, the library runs a "constructor" function to compute the number of capabilities of the running kernel [0], at the beginning of the execution of the program. As part of this, it performs multiple calls to prctl(). Some of these may fail, and set errno to a non-zero value:
# strace -e prctl ./bpftool version prctl(PR_CAPBSET_READ, CAP_MAC_OVERRIDE) = 1 prctl(PR_CAPBSET_READ, 0x30 /* CAP_??? */) = -1 EINVAL (Invalid argument) prctl(PR_CAPBSET_READ, CAP_CHECKPOINT_RESTORE) = 1 prctl(PR_CAPBSET_READ, 0x2c /* CAP_??? */) = -1 EINVAL (Invalid argument) prctl(PR_CAPBSET_READ, 0x2a /* CAP_??? */) = -1 EINVAL (Invalid argument) prctl(PR_CAPBSET_READ, 0x29 /* CAP_??? */) = -1 EINVAL (Invalid argument) ** fprintf added at the top of main(): we have errno == 1 ./bpftool v7.0.0 using libbpf v1.0 features: libbfd, libbpf_strict, skeletons +++ exited with 0 +++
This has been addressed in libcap 2.63 [1], but until this version is available everywhere, we can fix it on bpftool side.
Let's clean errno at the beginning of the main() function, to make sure that these checks do not interfere with the batch mode, where we error out if errno is set after a bpftool command.

Frames sent to userspace can be reported as dropped in ovs_dp_process_packet, however, if they are dropped in the netlink code then netlink_attachskb will report the same frame as dropped.
This patch checks for error codes which indicate that the frame has already been freed.

Currently queue_userspace_packet will call kfree_skb for all frames, whether or not an error occurred. This can result in a single dropped frame being reported as multiple drops in dropwatch. This functions caller may also call kfree_skb in case of an error. This patch will consume the skbs instead and allow caller's to use kfree_skb.

tcp_md5sig_pool_populated can be read while another thread changes its value.
The race has no consequence because allocations are protected with tcp_md5sig_mutex.
This patch adds READ_ONCE() and WRITE_ONCE() to document the race and silence KCSAN.

[ Upstream commit b383e8abed41cc6ff1a3b34de75df9397fa4878c ]
syzbot is reporting uninit value at ath9k_htc_rx_msg() [1], for ioctl(USB_RAW_IOCTL_EP_WRITE) can call ath9k_hif_usb_rx_stream() with pkt_len = 0 but ath9k_hif_usb_rx_stream() uses __dev_alloc_skb(pkt_len + 32, GFP_ATOMIC) based on an assumption that pkt_len is valid. As a result, ath9k_hif_usb_rx_stream() allocates skb with uninitialized memory and ath9k_htc_rx_msg() is reading from uninitialized memory.
Since bytes accessed by ath9k_htc_rx_msg() is not known until ath9k_htc_rx_msg() is called, it would be difficult to check minimal valid pkt_len at "if (pkt_len > 2 * MAX_RX_BUF_SIZE) {" line in ath9k_hif_usb_rx_stream().
We have two choices. One is to workaround by adding __GFP_ZERO so that ath9k_htc_rx_msg() sees 0 if pkt_len is invalid. The other is to let ath9k_htc_rx_msg() validate pkt_len before accessing. This patch chose the latter.
Note that I'm not sure threshold condition is correct, for I can't find details on possible packet length used by this protocol.

Currently if ipcomp_alloc_scratches() fails to allocate memory ipcomp_scratches holds obsolete address. So when we try to free the percpu scratches using ipcomp_free_scratches() it tries to vfree non existent vm area. Described below:
static void * __percpu *ipcomp_alloc_scratches(void) { ... scratches = alloc_percpu(void *); if (!scratches) return NULL; ipcomp_scratches does not know about this allocation failure. Therefore holding the old obsolete address. ... }
So when we free,
static void ipcomp_free_scratches(void) { ... scratches = ipcomp_scratches; Assigning obsolete address from ipcomp_scratches
if (!scratches) return;
for_each_possible_cpu(i) vfree(*per_cpu_ptr(scratches, i)); Trying to free non existent page, causing warning: trying to vfree existent vm area. ... }
Fix this breakage by updating ipcomp_scrtches with NULL when scratches is freed

By using a ratio of delay to poll_enabled_time that is not integer time_remaining underflows and does not exit the loop as expected. As delay could be derived from DT and poll_enabled_time is defined in the driver this can easily happen.
Use a signed iterator to make sure that the loop exits once the remaining time is negative.

[ Upstream commit 2d2cb3066f2c90cd8ca540b36ba7a55e7f2406e0 ]
syzbot is reporting cancel_delayed_work() without INIT_DELAYED_WORK() at l2cap_chan_del() [1], for CONF_NOT_COMPLETE flag (which meant to prevent l2cap_chan_del() from calling cancel_delayed_work()) is cleared by timer which fires before l2cap_chan_del() is called by closing file descriptor created by socket(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_L2CAP).
l2cap_bredr_sig_cmd(L2CAP_CONF_REQ) and l2cap_bredr_sig_cmd(L2CAP_CONF_RSP) are calling l2cap_ertm_init(chan), and they call l2cap_chan_ready() (which clears CONF_NOT_COMPLETE flag) only when l2cap_ertm_init(chan) succeeded.
l2cap_sock_init() does not call l2cap_ertm_init(chan), and it instead sets CONF_NOT_COMPLETE flag by calling l2cap_chan_set_defaults(). However, when connect() is requested, "command 0x0409 tx timeout" happens after 2 seconds from connect() request, and CONF_NOT_COMPLETE flag is cleared after 4 seconds from connect() request, for l2cap_conn_start() from l2cap_info_timeout() callback scheduled by
schedule_delayed_work(&conn->info_timer, L2CAP_INFO_TIMEOUT);
in l2cap_connect() is calling l2cap_chan_ready().
Fix this problem by initializing delayed works used by L2CAP_MODE_ERTM mode as soon as l2cap_chan_create() allocates a channel, like I did in commit be8597239379f0f5 ("Bluetooth: initialize skb_queue_head at l2cap_chan_create()").

While waiting for memory in thread1, the socket is released with its wait queue because thread2 has closed it. This caused by tcp_bpf_send_verdict didn't increase the f_count of psock->sk_redir->sk_socket->file in thread1.
We should check if SOCK_DEAD flag is set on wakeup in sk_stream_wait_memory before accessing the wait queue.

nouveau_bo_alloc() allocates a memory chunk for "nvbo" with kzalloc(). When some error occurs, "nvbo" should be released. But when WARN_ON(pi < 0)) equals true, the function return ERR_PTR without releasing the "nvbo", which will lead to a memory leak.
We should release the "nvbo" with kfree() if WARN_ON(pi < 0)) equals true.

[ Upstream commit 94dc3471d1b2b58b3728558d0e3f264e9ce6ff59 ]
The strlen() function returns a size_t which is an unsigned int on 32-bit arches and an unsigned long on 64-bit arches. But in the drm_copy_field() function, the strlen() return value is assigned to an 'int len' variable.
Later, the len variable is passed as copy_from_user() third argument that is an unsigned long parameter as well.
In theory, this can lead to an integer overflow via type conversion. Since the assignment happens to a signed int lvalue instead of a size_t lvalue.
In practice though, that's unlikely since the values copied are set by DRM drivers and not controlled by userspace. But using a size_t for len is the correct thing to do anyways.

There are some struct drm_driver fields that are required by drivers since drm_copy_field() attempts to copy them to user-space via DRM_IOCTL_VERSION.
But it can be possible that a driver has a bug and did not set some of the fields, which leads to drm_copy_field() attempting to copy a NULL pointer:

[ Upstream commit 6ae0632d17759852c07e2d1e0a31c728eb6ba246 ]
The definition of MIN_I64 in bw_fixed.c can cause gcc to whinge about integer overflow, because it is treated as a positive value, which is then negated. The temporary positive value is not necessarily representable.
This causes the following warning: ../drivers/gpu/drm/amd/amdgpu/../display/dc/dml/calcs/bw_fixed.c:30:19: warning: integer overflow in expression ‘-9223372036854775808’ of type ‘long long int’ results in ‘-9223372036854775808’ [-Woverflow] 30 | (int64_t)(-(1LL << 63)) | ^
Writing out (-MAX_I64 - 1) works instead.

[ Upstream commit d9c04a1b7a15b5e74b2977461d9511e497f05d8f ]
When userspace tries to map the dmabuf and if for some reason (e.g. OOM) the creation of the sg table fails, ubuf->sg needs to be set to NULL. Otherwise, when the userspace subsequently closes the dmabuf fd, we'd try to erroneously free the invalid sg table from release_udmabuf resulting in the following crash reported by syzbot:

[ Upstream commit da09daf881082266e4075657fac53c7966de8e4d ]
There are two events that signal a real change of the link state: HPD going high means the sink is newly connected or wants the source to re-read the EDID, RX sense going low is a indication that the link has been disconnected.
Ignore the other two events that also trigger interrupts, but don't need immediate attention: HPD going low does not necessarily mean the link has been lost and should not trigger a immediate read of the status. RX sense going high also does not require a detect cycle, as HPD going high is the right point in time to read the EDID.

This commit fixes vertical timings of the VEC (composite output) modes to accurately represent the 525-line ("NTSC") and 625-line ("PAL") ITU-R standards.
Previous timings were actually defined as 502 and 601 lines, resulting in non-standard 62.69 Hz and 52 Hz signals being generated, respectively.

cros_ec_handle_event in the cros_ec driver can notify the PM of wake events. When a device is suspended, cros_ec_handle_event will not check MKBP events. Instead, received MKBP events are checked during resume by cros_ec_report_events_during_suspend. But cros_ec_report_events_during_suspend cannot notify the PM if received events are wake events, causing wake events to not be reported if received while the device is suspended.
Update cros_ec_report_events_during_suspend to notify the PM of wake events during resume by calling pm_wakeup_event.

[ Upstream commit 2a2565272a3628e45d61625e36ef17af7af4e3de ]
On a MSI S270 with Fedora 37 x86_64 / systemd-251.4 the module does not properly autoload.
This is likely caused by issues with how systemd-udevd handles the single quote char (') which is part of the sys_vendor / chassis_vendor strings on this laptop. As a workaround remove the single quote char + everything behind it from the sys_vendor + chassis_vendor matches. This fixes the module not autoloading.

In some Chrome platforms if OEM's use their own string as SYS_VENDOR than "Google", it leads to firmware load failure from intel/sof/community path.
Hence, changing SYS_VENDOR to PRODUCT_FAMILY in which "Google" is used as common prefix and is supported in all Chrome platforms.

[ Upstream commit 8616f2a0589a80e08434212324250eb22f6a66ce ]
Because component_master_del wasn't being called when unloading the meson_drm module, the aggregate device would linger forever in the global aggregate_devices list. That means when unloading and reloading the meson_dw_hdmi module, component_add would call into try_to_bring_up_aggregate_device and find the unbound meson_drm aggregate device.
This would in turn dereference some of the aggregate_device's struct entries which point to memory automatically freed by the devres API when unbinding the aggregate device from meson_drv_unbind, and trigger an use-after-free bug:

--------------------------------
[ Upstream commit 7b4d8db657192066bc6f1f6635d348413dac1e18 ]
The sequence for Source DP PHY CTS automation is [2][1]: 1- Emulate successful Link Training(LT) 2- Short HPD and change link rates and number of lanes by LT. (This is same flow for Link Layer CTS) 3- Short HPD and change PHY test pattern and swing/pre-emphasis levels (This step should not trigger LT)
The problem is with DP PHY compliance setup as follow:
[DPTX + on board LTTPR]------Main Link--->[Scope] ^ | | | | | ----------Aux Ch------>[Aux Emulator]
At step 3, before writing TRAINING_LANEx_SET/LINK_QUAL_PATTERN_SET to declare the pattern/swing requested by scope, we write link config in LINK_BW_SET/LANE_COUNT_SET on a port that has LTTPR. As LTTPR snoops aux transaction, LINK_BW_SET/LANE_COUNT_SET writes indicate a LT will start [Check DP 2.0 E11 -Sec 3.6.8.2 & 3.6.8.6.3], and LTTPR will reset the link and stop sending DP signals to DPTX/Scope causing the measurements to fail. Note that step 3 will not trigger LT and DP link will never recovered by the Aux Emulator/Scope.
The reset of link can be tested with a monitor connected to LTTPR port simply by writing to LINK_BW_SET or LANE_COUNT_SET as follow
igt/tools/dpcd_reg write --offset=0x100 --value 0x14 --device=2
OR
printf '\x14' | sudo dd of=/dev/drm_dp_aux2 bs=1 count=1 conv=notrunc seek=$((0x100))
This single aux write causes the screen to blank, sending short HPD to DPTX, setting LINK_STATUS_UPDATE = 1 in DPCD 0x204, and triggering LT.
As stated in [1]: "Before any TX electrical testing can be performed, the link between a DPTX and DPRX (in this case, a piece of test equipment), including all LTTPRs within the path, shall be trained as defined in this Standard."
In addition, changing Phy pattern/Swing/Pre-emphasis (Step 3) uses the same link rate and lane count applied on step 2, so no need to redo LT.
The fix is to not rewrite link config in step 3, and just writes TRAINING_LANEx_SET and LINK_QUAL_PATTERN_SET

This will then cause the APP weston-touch-calibrator can't list touch devices.

[ Upstream commit 5c152c2f66f9368394b89ac90dc7483476ef7b88 ]
When arm64 signal context data overflows the base struct sigcontext it gets placed in an extra buffer pointed to by a record of type EXTRA_CONTEXT in the base struct sigcontext which is required to be the last record in the base struct sigframe. The current validation code attempts to check this by using GET_RESV_NEXT_HEAD() to step forward from the current record to the next but that is a macro which assumes it is being provided with a struct _aarch64_ctx and uses the size there to skip forward to the next record. Instead validate_extra_context() passes it a struct extra_context which has a separate size field. This compiles but results in us trying to validate a termination record in completely the wrong place, at best failing validation and at worst just segfaulting. Fix this by passing the struct _aarch64_ctx we meant to into the macro.

[ Upstream commit f9eab5f0bba76742af654f33d517bf62a0db8f12 ]
[BUG] The following script shows that, although scrub can detect super block errors, it never tries to fix it:
mkfs.btrfs -f -d raid1 -m raid1 $dev1 $dev2 xfs_io -c "pwrite 67108864 4k" $dev2
mount $dev1 $mnt btrfs scrub start -B $dev2 btrfs scrub start -Br $dev2 umount $mnt
The first scrub reports the super error correctly:
scrub done for f3289218-abd3-41ac-a630-202f766c0859 Scrub started: Tue Aug 2 14:44:11 2022 Status: finished Duration: 0:00:00 Total to scrub: 1.26GiB Rate: 0.00B/s Error summary: super=1 Corrected: 0 Uncorrectable: 0 Unverified: 0
But the second read-only scrub still reports the same super error:
Scrub started: Tue Aug 2 14:44:11 2022 Status: finished Duration: 0:00:00 Total to scrub: 1.26GiB Rate: 0.00B/s Error summary: super=1 Corrected: 0 Uncorrectable: 0 Unverified: 0
[CAUSE] The comments already shows that super block can be easily fixed by committing a transaction:
/* * If we find an error in a super block, we just report it. * They will get written with the next transaction commit * anyway */
But the truth is, such assumption is not always true, and since scrub should try to repair every error it found (except for read-only scrub), we should really actively commit a transaction to fix this.
[FIX] Just commit a transaction if we found any super block errors, after everything else is done.
We cannot do this just after scrub_supers(), as btrfs_commit_transaction() will try to pause and wait for the running scrub, thus we can not call it with scrub_lock hold.

"BUG: KASAN: stack-out-of-bounds in strncpy+0x30/0x68"
Linux-ATF interface is using 16 bytes of SMC payload. In case clock name is longer than 15 bytes, string terminated NULL character will not be received by Linux. Add explicit NULL character at last byte to fix issues when clock name is longer.
This fixes below bug reported by KASAN:

[ Upstream commit 2b064d91440b33fba5b452f2d1b31f13ae911d71 ]
When the driver calls cx88_risc_buffer() to prepare the buffer, the function call may fail, resulting in a empty buffer and null-ptr-deref later in buffer_queue().
The following log can reveal it:

--------------------------------
[ Upstream commit 30eaf02149ecc3c5815e45d27187bf09e925071d ]
The function zynqmp_pll_round_rate is used to find a most appropriate PLL frequency which the hardware can generate according to the desired frequency. For example, if the desired frequency is 297MHz, considering the limited range from PS_PLL_VCO_MIN (1.5GHz) to PS_PLL_VCO_MAX (3.0GHz) of PLL, zynqmp_pll_round_rate should return 1.872GHz (297MHz * 5).
There are two problems with the current code of zynqmp_pll_round_rate:
1) When the rate is below PS_PLL_VCO_MIN, it can't find a correct rate when the parameter "rate" is an integer multiple of *prate, in other words, if "f" is zero, zynqmp_pll_round_rate won't return a valid frequency which is from PS_PLL_VCO_MIN to PS_PLL_VCO_MAX. For example, *prate is 33MHz and the rate is 660MHz, zynqmp_pll_round_rate will not boost up rate and just return 660MHz, and this will cause clk_calc_new_rates failure since zynqmp_pll_round_rate returns an invalid rate out of its boundaries.
2) Even if the rate is higher than PS_PLL_VCO_MIN, there is still a risk that zynqmp_pll_round_rate returns an invalid rate because the function DIV_ROUND_CLOSEST makes some loss in the fractional part. If the parent clock *prate is 33333333Hz and we want to set the PLL rate to 1.5GHz, this function will return 1499999985Hz by using the formula below: value = *prate * DIV_ROUND_CLOSEST(rate, *prate)). This value is also invalid since it's slightly smaller than PS_PLL_VCO_MIN. because DIV_ROUND_CLOSEST makes some loss in the fractional part.

The original code will "goto out_disable_device" and call pci_disable_device() if pci_enable_device() fails. The kernel will generate a warning message like "3w-9xxx 0000:00:05.0: disabling already-disabled device".
We shouldn't disable a device that failed to be enabled. A simple return is fine.

syzbot reported hung task [1]. The following program is a simplified version of the reproducer:
int main(void) { int sv[2], fd;
if (socketpair(AF_UNIX, SOCK_STREAM, 0, sv) < 0) return 1; if ((fd = open("/dev/nbd0", 0)) < 0) return 1; if (ioctl(fd, NBD_SET_SIZE_BLOCKS, 0x81) < 0) return 1; if (ioctl(fd, NBD_SET_SOCK, sv[0]) < 0) return 1; if (ioctl(fd, NBD_DO_IT) < 0) return 1; return 0; }
When signal interrupt nbd_start_device_ioctl() waiting the condition atomic_read(&config->recv_threads) == 0, the task can hung because it waits the completion of the inflight IOs.
This patch fixes the issue by clearing queue, not just shutdown, when signal interrupt nbd_start_device_ioctl().

Modify the memory freeing loop to include the case i=0.

[ Upstream commit 3c132ea6508b34956e5ed88d04936983ec230601 ]
Having greater than AHCI_MAX_PORTS (32) ports detected isn't that critical from the further AHCI-platform initialization point of view since exceeding the ports upper limit will cause allocating more resources than will be used afterwards. But detecting too many child DT-nodes doesn't seem right since it's very unlikely to have it on an ordinary platform. In accordance with the AHCI specification there can't be more than 32 ports implemented at least due to having the CAP.NP field of 5 bits wide and the PI register of dword size. Thus if such situation is found the DTB must have been corrupted and the data read from it shouldn't be reliable. Let's consider that as an erroneous situation and halt further resources allocation.
Note it's logically more correct to have the nports set only after the initialization value is checked for being sane. So while at it let's make sure nports is assigned with a correct value.

[ Upstream commit d2d05b88035d2d51a5bb6c5afec88a0880c73df4 ]
Inside set_at_max_writeback_rate() the calculation in following if() check is wrong, if (atomic_inc_return(&c->idle_counter) < atomic_read(&c->attached_dev_nr) * 6)
Because each attached backing device has its own writeback thread running and increasing c->idle_counter, the counter increates much faster than expected. The correct calculation should be, (counter / dev_nr) < dev_nr * 6 which equals to, counter < dev_nr * dev_nr * 6
This patch fixes the above mistake with correct calculation, and helper routine idle_counter_exceeded() is added to make code be more clear.

The buf passed in struct sdw_msg must only be written for a READ, in that case the RDATA part of the response is the data value of the register.
For a write command there is no RDATA, and buf should be assumed to be const and unmodifable. The original caller should not expect its data buffer to be corrupted by an sdw_nwrite().

[ Upstream commit 5e2cf333b7bd5d3e62595a44d598a254c697cd74 ]
A complicated deadlock exists when using the journal and an elevated group_thrtead_cnt. It was found with loop devices, but its not clear whether it can be seen with real disks. The deadlock can occur simply by writing data with an fio script.
When the deadlock occurs, multiple threads will hang in different ways:
1) The group threads will hang in the blk-wbt code with bios waiting to be submitted to the block layer:
io_schedule+0x70/0xb0 rq_qos_wait+0x153/0x210 wbt_wait+0x115/0x1b0 io_schedule+0x70/0xb0 rq_qos_wait+0x153/0x210 wbt_wait+0x115/0x1b0 __rq_qos_throttle+0x38/0x60 blk_mq_submit_bio+0x589/0xcd0 wbt_wait+0x115/0x1b0 __rq_qos_throttle+0x38/0x60 blk_mq_submit_bio+0x589/0xcd0 __submit_bio+0xe6/0x100 submit_bio_noacct_nocheck+0x42e/0x470 submit_bio_noacct+0x4c2/0xbb0 ops_run_io+0x46b/0x1a30 handle_stripe+0xcd3/0x36b0 handle_active_stripes.constprop.0+0x6f6/0xa60 raid5_do_work+0x177/0x330
Or: io_schedule+0x70/0xb0 rq_qos_wait+0x153/0x210 wbt_wait+0x115/0x1b0 __rq_qos_throttle+0x38/0x60 blk_mq_submit_bio+0x589/0xcd0 __submit_bio+0xe6/0x100 submit_bio_noacct_nocheck+0x42e/0x470 submit_bio_noacct+0x4c2/0xbb0 flush_deferred_bios+0x136/0x170 raid5_do_work+0x262/0x330
2) The r5l_reclaim thread will hang in the same way, submitting a bio to the block layer:
io_schedule+0x70/0xb0 rq_qos_wait+0x153/0x210 wbt_wait+0x115/0x1b0 __rq_qos_throttle+0x38/0x60 blk_mq_submit_bio+0x589/0xcd0 __submit_bio+0xe6/0x100 submit_bio_noacct_nocheck+0x42e/0x470 submit_bio_noacct+0x4c2/0xbb0 submit_bio+0x3f/0xf0 md_super_write+0x12f/0x1b0 md_update_sb.part.0+0x7c6/0xff0 md_update_sb+0x30/0x60 r5l_do_reclaim+0x4f9/0x5e0 r5l_reclaim_thread+0x69/0x30b
However, before hanging, the MD_SB_CHANGE_PENDING flag will be set for sb_flags in r5l_write_super_and_discard_space(). This flag will never be cleared because the submit_bio() call never returns.
3) Due to the MD_SB_CHANGE_PENDING flag being set, handle_stripe() will do no processing on any pending stripes and re-set STRIPE_HANDLE. This will cause the raid5d thread to enter an infinite loop, constantly trying to handle the same stripes stuck in the queue.
The raid5d thread has a blk_plug that holds a number of bios that are also stuck waiting seeing the thread is in a loop that never schedules. These bios have been accounted for by blk-wbt thus preventing the other threads above from continuing when they try to submit bios. --Deadlock.
To fix this, add the same wait_event() that is used in raid5_do_work() to raid5d() such that if MD_SB_CHANGE_PENDING is set, the thread will schedule and wait until the flag is cleared. The schedule action will flush the plug which will allow the r5l_reclaim thread to continue, thus preventing the deadlock.
However, md_check_recovery() calls can also clear MD_SB_CHANGE_PENDING from the same thread and can thus deadlock if the thread is put to sleep. So avoid waiting if md_check_recovery() is being called in the loop.
It's not clear when the deadlock was introduced, but the similar wait_event() call in raid5_do_work() was added in 2017 by this commit:
16d997b78b15 ("md/raid5: simplfy delaying of writes while metadata is updated.")

[ Upstream commit ad5dbfc123e6ffbbde194e2a4603323e09f741ee ]
This reverts commit 86d92f5465958752481269348d474414dccb1552, which fix the timeout issue for "Samsung Fit Flash".
But the commit affects not only "Samsung Fit Flash" but also other usb storages that use the same controller and causes severe performance regression.
# hdparm -t /dev/sda (without the quirk) Timing buffered disk reads: 622 MB in 3.01 seconds = 206.66 MB/sec
# hdparm -t /dev/sda (with the quirk) Timing buffered disk reads: 220 MB in 3.00 seconds = 73.32 MB/sec
The commit author mentioned that "Issue was reproduced after device has bad block", so this quirk should be applied when we have the timeout issue with a device that has bad blocks.
We revert the commit so that we apply this quirk by adding kernel paramters using a bootloader or other ways when we really need it, without the performance regression with devices that don't have the issue.

[ Upstream commit 708056fba733a73d926772ea4ce9a42d240345da ]
In rtw_init_cmd_priv(), if `pcmdpriv->rsp_allocated_buf` is allocated in failure, then `pcmdpriv->cmd_allocated_buf` will be not properly released. Besides, considering there are only two error paths and the first one can directly return, so we do not need implicitly jump to the `exit` tag to execute the error handler.
So this patch added `kfree(pcmdpriv->cmd_allocated_buf);` on the error path to release the resource and simplified the return logic of rtw_init_cmd_priv(). As there is no proper device to test with, no runtime testing was performed.

In idmouse_create_image, if any ftip_command fails, it will go to the reset label. However, this leads to the data in bulk_in_buffer[HEADER..IMGSIZE] uninitialized. And the check for valid image incurs an uninitialized dereference.
Fix this by moving the check before reset label since this check only be valid if the data after bulk_in_buffer[HEADER] has concrete data.
Note that this is found by KMSAN, so only kernel compilation is tested.

[ Upstream commit 6c5422851d8be8c7451e968fd2e6da41b6109e17 ]
When testing for a series affecting the VEC, it was discovered that turning off and on the VEC clock is crashing the system.
It turns out that, when disabling the VEC clock, it's the only child of the PLLC-per clock which will also get disabled. The source of the crash is PLLC-per being disabled.
It's likely that some other device might not take a clock reference that it actually needs, but it's unclear which at this point. Let's make PLLC-per critical so that we don't have that crash.

uClibc segfaulted because NULL was passed as the format to fprintf().
That happened because one of the format strings was missing and intel_pt_print_info() didn't check that before calling fprintf().
Add the missing format string, and check format is not NULL before calling fprintf().

Since PF_IEEE802154 socket's zero-sized raw_sendmsg() request was able to return 0, don't call __dev_queue_xmit() if packet length is 0.

commit 4bb7f6c2781e46fc5bd00475a66df2ea30ef330d upstream.
Commit 68b99e94a4a2 ("thermal: intel_powerclamp: Use get_cpu() instead of smp_processor_id() to avoid crash") fixed an issue related to using smp_processor_id() in preemptible context by replacing it with a pair of get_cpu()/put_cpu(), but what is needed there really is any online CPU and not necessarily the one currently running the code. Arguably, getting the one that's running the code in there is confusing.
For this reason, simply give the control CPU role to the first online one which automatically will be CPU0 if it is online, so one check can be dropped from the code for an added benefit.

commit cd6d697a6e2013a0a85f8b261b16c8cfd50c1f5f upstream.
In f2fs_balance_fs_bg(), it needs to check both NAT_ENTRIES and INO_ENTRIES memory usage to decide whether we should skip background checkpoint, otherwise we may always skip checking INO_ENTRIES memory usage, so that INO_ENTRIES may potentially cause high memory footprint.

commit 977ef30a7d888eeb52fb6908f99080f33e5309a8 upstream.
Starting with GCC 12.1, the created .gcda format can't be read by gcov tool. There are 2 significant changes to the .gcda file format that need to be supported:
a) [gcov: Use system IO buffering] (23eb66d1d46a34cb28c4acbdf8a1deb80a7c5a05) changed that all sizes in the format are in bytes and not in words (4B)
b) [gcov: make profile merging smarter] (72e0c742bd01f8e7e6dcca64042b9ad7e75979de) add a new checksum to the file header.
Tested with GCC 7.5, 10.4, 12.2 and the current master.

The patches that this patch depends on were not backported properly and the patch that caused the regression that this patch set fixed was reverted in commit 412b844143e3 ("Revert "PCI/portdrv: Don't disable AER reporting in get_port_device_capability()""). This isn't necessary and causes a regression so drop it.
