Often this would cause strange crashes as the mutexes would be freed while they were being used. Looking at the code, there is a lifetime problem as the controlling thread that spawns the work allocates the "struct stress" structures that are passed to the workqueue threads. Then when the workqueue threads are finished, they free the stress struct that was passed to them. Unfortunately the workqueue work_struct node is in the stress struct. Which means the work_struct is freed before the work thread returns and while flush_workqueue is waiting. It seems like a better idea to have the controlling thread both allocate and free the stress structures, so that we can be sure we don't corrupt the workqueue by freeing the structure prematurely. So this patch reworks the test to do so, and with this change I no longer see the early flush_workqueue returns.

From: Zheng Zengkai <zhengzengkai@huawei.com> From: Filipe Manana <fdmanana@suse.com> stable inclusion from stable-v6.6.3 commit d5e09e385e8abfdbbd9af3e2c83e4e8ca854f2ef category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8LBQP Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 50564b651d01c19ce732819c5b3c3fd60707188e ] When marking an extent buffer as dirty, at btrfs_mark_buffer_dirty(), we check if its generation matches the running transaction and if not we just print a warning. Such mismatch is an indicator that something really went wrong and only printing a warning message (and stack trace) is not enough to prevent a corruption. Allowing a transaction to commit with such an extent buffer will trigger an error if we ever try to read it from disk due to a generation mismatch with its parent generation. So abort the current transaction with -EUCLEAN if we notice a generation mismatch. For this we need to pass a transaction handle to btrfs_mark_buffer_dirty() which is always available except in test code, in which case we can pass NULL since it operates on dummy extent buffers and all test roots have a single node/leaf (root node at level 0).

As David Kaplan describes in his debugging of the issue, it is caused by a couple of KCSAN-generated constructors which aren't processed by objtool: "When KCSAN is enabled, GCC generates lots of constructor functions named _sub_I_00099_0 which call __tsan_init and then return. The returns in these are generally annotated normally by objtool and fixed up at runtime. But objtool runs on vmlinux.o and vmlinux.o does not include a couple of object files that are in vmlinux, like init/version-timestamp.o and .vmlinux.export.o, both of which contain _sub_I_00099_0 functions. As a result, the returns in these functions are not annotated, and the panic occurs when we call one of them in do_ctors and it uses the default return thunk. This difference can be seen by counting the number of these functions in the object files: $ objdump -d vmlinux.o|grep -c "<_sub_I_00099_0>:" 2601 $ objdump -d vmlinux|grep -c "<_sub_I_00099_0>:" 2603 If these functions are only run during kernel boot, there is no speculation concern." Fix it by disabling KCSAN on version-timestamp.o and .vmlinux.export.o so the extra functions don't get generated. KASAN and GCOV are already disabled for those files.

The maximum result of this subtraction is defined by the RCU_FANOUT_LEAF Kconfig option, which on 64-bit systems defaults to 16 (resulting in a maximum shift of 15), but which can be set up as high as 64 (resulting in a maximum shift of 63). A value of 31 can result in sign extension, resulting in 0xffffffff80000000 instead of the desired 0x80000000. A value of 32 or greater triggers undefined behavior per the C standard. This bug has not been known to cause issues because almost all kernels take the default CONFIG_RCU_FANOUT_LEAF=16. Furthermore, as long as a given compiler gives a deterministic non-zero result for 1<<N for N>=32, the code correctly invokes all SRCU callbacks, albeit wasting CPU time along the way. This commit therefore substitutes the correct 1UL for the buggy 1. Found by Linux Verification Center (linuxtesting.org) with SVACE.

However, after this [1] commit, UBSAN is triggered under many new scenarios that weren't detected before, such as in struct definitions with fixed-size trailing arrays used as flexible arrays. As a result, CONFIG_UBSAN_TRAP=y has become a very aggressive option to enable except for specific situations. `make kselftest-merge` applies CONFIG_UBSAN_TRAP=y to the kernel config for all selftests, which makes many of them fail because of system hangs during boot. This change removes the config option from the lkdtm kselftest and configures the ARRAY_BOUNDS test to look for UBSAN reports rather than relying on the calling process being killed.

The driver initially triggers a reset-to-zero of the two timers but this reset is only performed on the next rising clock. For the first timer this is ok - it will be in the next 60ns (16MHz clock). For the chained second timer this will only happen after the first timer overflows, i.e. after 2^16 clocks (~4ms with a 16MHz clock). So with other words the scheduler clock resets to 0 after the first 2^16 clock cycles. It looks like that the scheduler does not like this and behaves wrongly over its lifetime, e.g. some tasks are scheduled with a long delay. Why that is and if there are additional requirements for this behaviour has not been further analysed. There is a simple fix for resetting the second timer as well when the first timer is reset and this is to set the ATMEL_TC_ASWTRG_SET bit in the Channel Mode register (CMR) of the first timer. This will also rise the TIOA line (clock input of the second timer) when a software trigger respective SYNC is issued.

When it gets stuck temporarily, it usually gets released in a few seconds, and sometimes up to one or two minutes. If the CSD lock stays stuck for more than several minutes, it never seems to get unstuck, and gradually more and more things in the system end up also getting stuck. In the latter case, we should just give up, so the system can dump out a little more information about what went wrong, and, with panic_on_oops and a kdump kernel loaded, dump a whole bunch more information about what might have gone wrong. In addition, there is an smp.panic_on_ipistall kernel boot parameter that by default retains the old behavior, but when set enables the panic after the CSD lock has been stuck for more than the specified number of milliseconds, as in 300,000 for five minutes.

As a result the workqueue related locking scenario for a function A may be spuriously accounted as an inversion against the locking scenario of function B such as in the following model: long A(void *arg) { mutex_lock(&mutex); mutex_unlock(&mutex); } long B(void *arg) { } void launchA(void) { work_on_cpu(0, A, NULL); } void launchB(void) { mutex_lock(&mutex); work_on_cpu(1, B, NULL); mutex_unlock(&mutex); } launchA and launchB running concurrently have no chance to deadlock. However the above can be reported by lockdep as a possible locking inversion because the works containing A() and B() are treated as belonging to the same locking class. The following shows an existing example of such a spurious lockdep splat: ====================================================== WARNING: possible circular locking dependency detected 6.6.0-rc1-00065-g934ebd6e5359 #35409 Not tainted ------------------------------------------------------ kworker/0:1/9 is trying to acquire lock: ffffffff9bc72f30 (cpu_hotplug_lock){++++}-{0:0}, at: _cpu_down+0x57/0x2b0 but task is already holding lock: ffff9e3bc0057e60 ((work_completion)(&wfc.work)){+.+.}-{0:0}, at: process_scheduled_works+0x216/0x500 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #2 ((work_completion)(&wfc.work)){+.+.}-{0:0}: __flush_work+0x83/0x4e0 work_on_cpu+0x97/0xc0 rcu_nocb_cpu_offload+0x62/0xb0 rcu_nocb_toggle+0xd0/0x1d0 kthread+0xe6/0x120 ret_from_fork+0x2f/0x40 ret_from_fork_asm+0x1b/0x30 -> #1 (rcu_state.barrier_mutex){+.+.}-{3:3}: __mutex_lock+0x81/0xc80 rcu_nocb_cpu_deoffload+0x38/0xb0 rcu_nocb_toggle+0x144/0x1d0 kthread+0xe6/0x120 ret_from_fork+0x2f/0x40 ret_from_fork_asm+0x1b/0x30 -> #0 (cpu_hotplug_lock){++++}-{0:0}: __lock_acquire+0x1538/0x2500 lock_acquire+0xbf/0x2a0 percpu_down_write+0x31/0x200 _cpu_down+0x57/0x2b0 __cpu_down_maps_locked+0x10/0x20 work_for_cpu_fn+0x15/0x20 process_scheduled_works+0x2a7/0x500 worker_thread+0x173/0x330 kthread+0xe6/0x120 ret_from_fork+0x2f/0x40 ret_from_fork_asm+0x1b/0x30 other info that might help us debug this: Chain exists of: cpu_hotplug_lock --> rcu_state.barrier_mutex --> (work_completion)(&wfc.work) Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock((work_completion)(&wfc.work)); lock(rcu_state.barrier_mutex); lock((work_completion)(&wfc.work)); lock(cpu_hotplug_lock); *** DEADLOCK *** 2 locks held by kworker/0:1/9: #0: ffff900481068b38 ((wq_completion)events){+.+.}-{0:0}, at: process_scheduled_works+0x212/0x500 #1: ffff9e3bc0057e60 ((work_completion)(&wfc.work)){+.+.}-{0:0}, at: process_scheduled_works+0x216/0x500 stack backtrace: CPU: 0 PID: 9 Comm: kworker/0:1 Not tainted 6.6.0-rc1-00065-g934ebd6e5359 #35409 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.12.0-59-gc9ba5276e321-prebuilt.qemu.org 04/01/2014 Workqueue: events work_for_cpu_fn Call Trace: rcu-torture: rcu_torture_read_exit: Start of episode <TASK> dump_stack_lvl+0x4a/0x80 check_noncircular+0x132/0x150 __lock_acquire+0x1538/0x2500 lock_acquire+0xbf/0x2a0 ? _cpu_down+0x57/0x2b0 percpu_down_write+0x31/0x200 ? _cpu_down+0x57/0x2b0 _cpu_down+0x57/0x2b0 __cpu_down_maps_locked+0x10/0x20 work_for_cpu_fn+0x15/0x20 process_scheduled_works+0x2a7/0x500 worker_thread+0x173/0x330 ? __pfx_worker_thread+0x10/0x10 kthread+0xe6/0x120 ? __pfx_kthread+0x10/0x10 ret_from_fork+0x2f/0x40 ? __pfx_kthread+0x10/0x10 ret_from_fork_asm+0x1b/0x30 </TASK Fix this with providing one lock class key per work_on_cpu() caller.

The commit: 9391a3f9c7f1 ("[PATCH] x86_64: Clear more state when ignoring empty node in SRAT parsing") ... that introduced minimal size of a NUMA node does not explain why a node size cannot be less than 4MB and what boot failures this restriction might fix. Fixes have been submitted to the core MM code to tighten up the memory topologies it accepts and to not crash on weird input: mm: page_alloc: skip memoryless nodes entirely mm: memory_hotplug: drop memoryless node from fallback lists Andrew has accepted them into the -mm tree, but there are no stable SHA1's yet. This patch drops the limitation for minimal node size on x86: - which works around the crash without the fixes to the core MM. - makes x86 topologies less weird, - removes an arbitrary and undocumented limitation on NUMA topologies.

In the above scenario, a fragmented packet is received for self peer, for which rx_tid and rx_frags are not initialized in datapath. While handling this fragment, crash is observed as the rx_frag list is uninitialized and when we walk in ath12k_dp_rx_h_sort_frags, skb null leads to exception. To address this, before processing received fragments we check dp_setup_done flag is set to ensure that peer has completed its dp peer setup for fragment queue, else ignore processing the fragments.

The alx and atl1c drivers had RX overflow error which was why a custom allocator was created to avoid certain addresses. The simpler workaround then created for alx driver, but not for atl1c due to lack of tester. Instead of using a custom allocator, check the allocated skb address and use skb_reserve() to move away from problematic 0x...fc0 address. Tested on AR8131 on Acer 4540.

For one, any instruction following a bpf_throw call will never be marked as seen. Moreover, if a callchain ends up throwing, any instructions after the call instruction to the eventually throwing subprog in callers will also never be marked as seen. The tempting way to fix this would be to emit extra 'int3' instructions which bump the jited_len of a program, and ensure that during runtime when a program throws, we can discover its boundaries even if the call instruction to bpf_throw (or to subprogs that always throw) is emitted as the final instruction in the program. An example of such a program would be this: do_something(): ... r0 = 0 exit foo(): r1 = 0 call bpf_throw r0 = 0 exit bar(cond): if r1 != 0 goto pc+2 call do_something exit call foo r0 = 0 // Never seen by verifier exit // main(ctx): r1 = ... call bar r0 = 0 exit Here, if we do end up throwing, the stacktrace would be the following: bpf_throw foo bar main In bar, the final instruction emitted will be the call to foo, as such, the return address will be the subsequent instruction (which the JIT emits as int3 on x86). This will end up lying outside the jited_len of the program, thus, when unwinding, we will fail to discover the return address as belonging to any program and end up in a panic due to the unreliable stack unwinding of BPF programs that we never expect. To remedy this case, make bpf_prog_ksym_find treat IP == ksym.end as part of the BPF program, so that is_bpf_text_address returns true when such a case occurs, and we are able to unwind reliably when the final instruction ends up being a call instruction.

This chip works flawlessly with the mt7921e module. The driver doesn't bind to this PCI device, because the Vendor ID from "ITTIM Technology" is not recognized. This patch adds the PCI Vendor ID from "ITTIM Technology" to the list of PCI Vendor IDs and lets the mt7921e driver bind to the mentioned wifi chip.

Or, worst case, on the separate line repeating instruction index. E.g., a nice and simple case would be: 2: (d5) if r0 s<= 0x0 goto pc+1 ; R0_w=0 But if there is some intervening extra output (e.g., precision backtracking log) involved, we are supposed to see the state after the precision backtrack log: 4: (75) if r0 s>= 0x0 goto pc+1 mark_precise: frame0: last_idx 4 first_idx 0 subseq_idx -1 mark_precise: frame0: regs=r0 stack= before 2: (d5) if r0 s<= 0x0 goto pc+1 mark_precise: frame0: regs=r0 stack= before 1: (b7) r0 = 0 6: R0_w=0 First off, note that in `6: R0_w=0` instruction index corresponds to the next instruction, not to the conditional jump instruction itself, which is wrong and we'll get to that. But besides that, the above is a happy case that does work today. Yet, if it so happens that precision backtracking had to traverse some of the parent states, this `6: R0_w=0` state output would be missing. This is due to a quirk of print_verifier_state() routine, which performs mark_verifier_state_clean(env) at the end. This marks all registers as "non-scratched", which means that subsequent logic to print *relevant* registers (that is, "scratched ones") fails and doesn't see anything relevant to print and skips the output altogether. print_verifier_state() is used both to print instruction context, but also to print an **entire** verifier state indiscriminately, e.g., during precision backtracking (and in a few other situations, like during entering or exiting subprogram). Which means if we have to print entire parent state before getting to printing instruction context state, instruction context is marked as clean and is omitted. Long story short, this is definitely not intentional. So we fix this behavior in this patch by teaching print_verifier_state() to clear scratch state only if it was used to print instruction state, not the parent/callback state. This is determined by print_all option, so if it's not set, we don't clear scratch state. This fixes missing instruction state for these cases. As for the mismatched instruction index, we fix that by making sure we call print_insn_state() early inside check_cond_jmp_op() before we adjusted insn_idx based on jump branch taken logic. And with that we get desired correct information: 9: (16) if w4 == 0x1 goto pc+9 mark_precise: frame0: last_idx 9 first_idx 9 subseq_idx -1 mark_precise: frame0: parent state regs=r4 stack=: R2_w=1944 R4_rw=P1 R10=fp0 mark_precise: frame0: last_idx 8 first_idx 0 subseq_idx 9 mark_precise: frame0: regs=r4 stack= before 8: (66) if w4 s> 0x3 goto pc+5 mark_precise: frame0: regs=r4 stack= before 7: (b7) r4 = 1 9: R4=1 Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: John Fastabend <john.fastabend@gmail.com> Acked-by: Eduard Zingerman <eddyz87@gmail.com> Link: https://lore.kernel.org/bpf/20231011223728.3188086-6-andrii@kernel.org Signed-off-by: Sasha Levin <sashal@kernel.org> Signed-off-by: Zheng Zengkai <zhengzengkai@huawei.com> --- kernel/bpf/verifier.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/kernel/bpf/verifier.c b/kernel/bpf/verifier.c index 82c9e5c47031..6542685d6772 100644 --- a/kernel/bpf/verifier.c +++ b/kernel/bpf/verifier.c @@ -1515,7 +1515,8 @@ static void print_verifier_state(struct bpf_verifier_env *env, if (state->in_async_callback_fn) verbose(env, " async_cb"); verbose(env, "\n"); - mark_verifier_state_clean(env); + if (!print_all) + mark_verifier_state_clean(env); } static inline u32 vlog_alignment(u32 pos) @@ -14139,6 +14140,8 @@ static int check_cond_jmp_op(struct bpf_verifier_env *env, !sanitize_speculative_path(env, insn, *insn_idx + 1, *insn_idx)) return -EFAULT; + if (env->log.level & BPF_LOG_LEVEL) + print_insn_state(env, this_branch->frame[this_branch->curframe]); *insn_idx += insn->off; return 0; } else if (pred == 0) { @@ -14151,6 +14154,8 @@ static int check_cond_jmp_op(struct bpf_verifier_env *env, *insn_idx + insn->off + 1, *insn_idx)) return -EFAULT; + if (env->log.level & BPF_LOG_LEVEL) + print_insn_state(env, this_branch->frame[this_branch->curframe]); return 0; } -- 2.20.1

After releasing an object using hci_conn_del_sysfs in the hci_conn_cleanup function, releasing the same object again using the hci_dev_put and hci_conn_put functions causes a double free. Here's a simplified flow: hci_conn_del_sysfs: hci_dev_put put_device kobject_put kref_put kobject_release kobject_cleanup kfree_const kfree(name) hci_dev_put: ... kfree(name) hci_conn_put: put_device ... kfree(name) This patch drop the hci_dev_put and hci_conn_put function call in hci_conn_cleanup function, because the object is freed in hci_conn_del_sysfs function.

At the ACPI level an _AEI event-handler is connected which sets an ACPI variable to 1 on both edges. This variable can be polled + cleared to 0 using WMI. Since the variable is set on both edges the WMI interface is pretty useless even when polling. So instead of writing a custom WMI driver for this the x86-android-tablets code instantiates a gpio-keys platform device for the "dolby" button. Add an ignore_interrupt quirk for INT33FC:00 pin 3 on the Peaq C1010, so that it is not seen as busy when the gpio-keys driver requests it. Note this replaces a hack in x86-android-tablets where it would call acpi_gpiochip_free_interrupts() on the INT33FC:00 GPIO controller. acpi_gpiochip_free_interrupts() is considered private (internal) gpiolib API so x86-android-tablets should stop using it.

A range item property for a PCI device is filled as follow: <BAR_nbr> 0 0 <phys.hi> <phys.mid> <phys.low> <BAR_sizeh> <BAR_sizel> <-- Child --> <-- Parent (PCI definition) --> <- BAR size (64bit) --> This allow to translate BAR addresses from the DT. For instance: pci@0,0 { #address-cells = <0x03>; #size-cells = <0x02>; device_type = "pci"; compatible = "pci11ab,100", "pciclass,060400", "pciclass,0604"; ranges = <0x82000000 0x00 0xe8000000 0x82000000 0x00 0xe8000000 0x00 0x4400000>; ... dev@0,0 { #address-cells = <0x03>; #size-cells = <0x02>; compatible = "pci1055,9660", "pciclass,020000", "pciclass,0200"; /* Translations for BAR0 to BAR5 */ ranges = <0x00 0x00 0x00 0x82010000 0x00 0xe8000000 0x00 0x2000000 0x01 0x00 0x00 0x82010000 0x00 0xea000000 0x00 0x1000000 0x02 0x00 0x00 0x82010000 0x00 0xeb000000 0x00 0x800000 0x03 0x00 0x00 0x82010000 0x00 0xeb800000 0x00 0x800000 0x04 0x00 0x00 0x82010000 0x00 0xec000000 0x00 0x20000 0x05 0x00 0x00 0x82010000 0x00 0xec020000 0x00 0x2000>; ... pci-ep-bus@0 { #address-cells = <0x01>; #size-cells = <0x01>; compatible = "simple-bus"; /* Translate 0xe2000000 to BAR0 and 0xe0000000 to BAR1 */ ranges = <0xe2000000 0x00 0x00 0x00 0x2000000 0xe0000000 0x01 0x00 0x00 0x1000000>; ... }; }; }; During the translation process, the "default-flags" map() function is used to select the matching item in the ranges table and determine the address offset from this matching item. This map() function simply calls of_read_number() and when address-size is greater than 2, the map() function skips the extra high address part (ie part over 64bit). This lead to a wrong matching item and a wrong offset computation. Also during the translation itself, the extra high part related to the parent address is not present in the translated address. Fix the "default-flags" map() and translate() in order to take into account the child extra high address part in map() and the parent extra high address part in translate() and so having a correct address translation for ranges patterns such as the one given in the example above.

On the currently problemtic machine (HP Omni 120) EDID reports the following mode: "1600x900": 60 108000 1600 1780 1860 1800 900 910 913 1000 0x40 0x5 which is then "corrected" to have htotal=1861 by the current drm_edid.c code. The fixup code was originally added in commit 7064fef56369 ("drm: work around EDIDs with bad htotal/vtotal values"). Googling around we end up in https://bugs.launchpad.net/ubuntu/hardy/+source/xserver-xorg-video-intel/+bu... where we find an EDID for a Dell Studio 15, which reports: (II) VESA(0): clock: 65.0 MHz Image Size: 331 x 207 mm (II) VESA(0): h_active: 1280 h_sync: 1328 h_sync_end 1360 h_blank_end 1337 h_border: 0 (II) VESA(0): v_active: 800 v_sync: 803 v_sync_end 809 v_blanking: 810 v_border: 0 Note that if we use the hblank size (as opposed of the hsync_end) from the DTD to determine htotal we get exactly 60Hz refresh rate in both cases, whereas using hsync_end to determine htotal we get a slightly lower refresh rates. This makes me believe the using the hblank size is what was intended even in those cases. Also note that in case of the HP Onmi 120 the VBIOS boots with these: crtc timings: 108000 1600 1780 1860 1800 900 910 913 1000, type: 0x40 flags: 0x5 ie. it just blindly stuffs the bogus hsync_end and htotal from the DTD into the transcoder timing registers, and the display works. I believe the (at least more modern) hardware will automagically terminate the hsync pulse when the timing generator reaches htotal, which again points that we should use the hblank size to determine htotal. Unfortunatley the old bug reports for the Dell machines are extremely lacking in useful details so we have no idea what kind of timings the VBIOS programmed into the hardware :( Let's just flip this quirk around and reduce the length of the sync pulse instead of extending the blanking period. This at least seems to be the correct thing to do on more modern hardware. And if any issues crop up on older hardware we need to debug them properly. v2: Add debug message breadcrumbs (Jani) Reviewed-by: Jani Nikula <jani.nikula@intel.com> Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/8895 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230920211934.14920-1-ville.s...

Hence caller must hold 'reconfig_mutex' and guarantee 'mddev->pers' is set before calling mddev_suspend(). Now that 'active_io' is initialized when mddev is allocated, such restriction doesn't exist anymore.

Sometimes the checks are done manually; sometimes the array size is calculated with array_size() and sometimes by calculating n * size directly in code. Introduce wrappers for arrays for memdup_user() and vmemdup_user() to provide a standardized and safe way for duplicating user arrays. This is both for new code as well as replacing usage of (v)memdup_user() in existing code that uses, e.g., n * size to calculate array sizes.

Skip the validity check. For the most part (*), the EDIDs returned by drm_get_edid() will be valid anyway, and there's the CTS workaround to get the checksum for completely invalid EDIDs. See commit 7948fe12d47a ("drm/msm/dp: return correct edid checksum after corrupted edid checksum read"). This lets us remove one user of drm_edid_block_valid() with hopes the function can be removed altogether in the future. (*) drm_get_edid() ignores checksum errors on CTA extensions.

The PCI specification provides two registers to store a vendor-specific SSID that can be read by drivers to uniquely identify a particular "soundcard". This is defined in the PCI specification to distinguish products that use the same silicon (and therefore have the same silicon ID) so that product-specific differences can be applied. PCI only defines 0xFFFF as an invalid value. 0x0000 is not defined as invalid. So the usual pattern of zero-filling the struct and then assuming a zero value unset will not work. A flag is included to indicate when the SSID information has been filled in. Unlike DMI information, which has a free-format entirely up to the vendor, the PCI SSID has a strictly defined format and a registry of vendor IDs. It is usual in Windows drivers that the SSID is used as the sole identifier of the specific end-product and the Windows driver contains tables mapping that to information about the hardware setup, rather than using ACPI properties. This SSID is important information for ASoC components that need to apply hardware-specific configuration on PCI-based systems. As the SSID is a generic part of the PCI specification and is treated as identifying the "soundcard", it is reasonable to include this information in struct snd_soc_card, instead of components inventing their own custom ways to pass this information around.

This allows the machine driver to use the SSID to uniquely identify the specific hardware configuration and apply any platform-specific configuration. struct snd_sof_pdata is passed around inside the SOF code, but it then passes configuration information to the machine driver through struct snd_soc_acpi_mach and struct snd_soc_acpi_mach_params. So SSID information has been added to both snd_sof_pdata and snd_soc_acpi_mach_params. PCI does not define 0x0000 as an invalid value so we can't use zero to indicate that the struct member was not written. Instead a flag is included to indicate that a value has been written to the subsystem_vendor and subsystem_device members. sof_pci_probe() creates the struct snd_sof_pdata. It is passed a struct pci_dev so it can fill in the SSID value. sof_machine_check() finds the appropriate struct snd_soc_acpi_mach. It copies the SSID information across to the struct snd_soc_acpi_mach_params. This done before calling any custom set_mach_params() so that it could be used by the set_mach_params() callback to apply variant params.

On PCI-based systems the PCI SSID is used to uniquely identify the specific sound hardware. This is the standard mechanism for x86 systems and is the way to get a unique system identifier for systems that use the CS35L56 on SoundWire. For non-SoundWire systems there is no Windows equivalent of the ASoC driver in I2C/SPI mode. These would be: 1. HDA systems, which are handled by the HDA subsystem. 2. Linux-specific systems. 3. Composite devices where the cs35l56 is not present in ACPI and is configured using software nodes. Case 2 can use the firmware-uid property, though the PCI SSID is supported as an alternative, as it is the standard PCI mechanism. Case 3 is a SoundWire system where some other codec is the SoundWire bridge device and CS35L56 is not listed in ACPI. As these are SoundWire systems they will normally use the PCI SSID.

In normal case, aead_request_complete() will be called in pcrypt_aead_serial and the return err is 0 for padata_do_parallel. But, when pinst->flags is PADATA_RESET, the return err is -EBUSY for padata_do_parallel, and it won't call aead_request_complete(). Therefore, test_aead_vec_cfg will hung at wait_for_completion(&wait->completion), which will cause hungtask. The problem comes as following: (padata_do_parallel) | rcu_read_lock_bh(); | err = -EINVAL; | (padata_replace) | pinst->flags |= PADATA_RESET; err = -EBUSY | if (pinst->flags & PADATA_RESET) | rcu_read_unlock_bh() | return err In order to resolve the problem, we replace the return err -EBUSY with -EAGAIN, which means parallel_data is changing, and the caller should call it again. v3: remove retry and just change the return err. v2: introduce padata_try_do_parallel() in pcrypt_aead_encrypt and pcrypt_aead_decrypt to solve the hungtask.

From: Zheng Zengkai <zhengzengkai@huawei.com> From: Tyrel Datwyler <tyreld@linux.ibm.com> stable inclusion from stable-v6.6.3 commit 8bbe784c2ff28d56ca0c548aaf3e584edc77052d category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8LBQP Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit b39f2d10b86d0af353ea339e5815820026bca48f ] In practice the driver should never send more commands than are allocated to a queue's event pool. In the unlikely event that this happens, the code asserts a BUG_ON, and in the case that the kernel is not configured to crash on panic returns a junk event pointer from the empty event list causing things to spiral from there. This BUG_ON is a historical artifact of the ibmvfc driver first being upstreamed, and it is well known now that the use of BUG_ON is bad practice except in the most unrecoverable scenario. There is nothing about this scenario that prevents the driver from recovering and carrying on. Remove the BUG_ON in question from ibmvfc_get_event() and return a NULL pointer in the case of an empty event pool. Update all call sites to ibmvfc_get_event() to check for a NULL pointer and perfrom the appropriate failure or recovery action.

Commit 3cb5ff0220e3 ("HID: lenovo: Hide middle-button press until release") workarounds last issue but it's impossible to workaround scrolling-related issues without firmware modification. Likely, Dennis Schneider has reverse engineered the firmware and provided an instruction on how to patch it [1]. However, aforementioned workaround prevents userspace (libinput) from knowing exact moment when middle button has been pressed down and performing "On-Button scrolling". This commit detects correctly-behaving patched firmware if cursor movement events has been received during middle button being pressed and stops applying workaround for this device.

Workaround this with a new snd_soc_acpi_intel_baytrail_machines[] entry which matches on the SST id instead of the codec id like nocodec does, combined with using a machine_quirk callback which returns NULL on other machines to skip the new entry on other machines.

When the workqueue receiving messages and performing callback processing, there are a large number of messages that need to be received, and there are continuously messages that have been processed and need to be received. This will cause the receive loop here to be locked for a long time. This scenario will cause watchdog timeout problems on OS with kernel preemption turned off.

The intention is to wait for the device to retry the wakeup event if the USB3 PORTSC doesn't reflect the RESUME link status by the time it is checked. As per the USB3 specification: tU3WakeupRetryDelay ("Table 7-12. LTSSM State Transition Timeouts") This would allow the XHCI resume sequence to determine if the root hub needs to be also resumed. However, in case there is no device connected, or if there is only a HSUSB device connected, this delay would still affect the overall resume timing. Since this delay is solely for detecting U3 wake events (USB3 specific) then ignore this delay for the disconnected case and the HSUSB connected only case.

Nevertheless, the gadget pointer could change during bind/unbind cycles due to various conditions, including the unloading/loading of the UDC device driver or the detachment/reconnection of an OTG-capable USB hub device. This patch relocates the gether_set_gadget() function out from ncm_opts->bound condition check, ensuring that the correct gadget is assigned during each bind request.

If the timing is right, function do_qc can add pending quota changes to a transaction, then later, another call to do_qc can negate those changes, resulting in a net gain of 0. The quota_change information is recorded in the qc buffer (and qd element of the inode as well). The buffer is added to the transaction by the first call to do_qc, but a subsequent call changes the value from non-zero back to zero. At that point it's too late to remove the buffer_head from the transaction. Later, when the quota sync code is called, the zero-change qd element is discovered and flagged as an assert warning. If the fs is mounted with errors=panic, the kernel will panic. This is usually seen when files are truncated and the quota changes are negated by punch_hole/truncate which uses gfs2_quota_hold and gfs2_quota_unhold rather than block allocations that use gfs2_quota_lock and gfs2_quota_unlock which automatically do quota sync. This patch solves the problem by adding a check to qd_check_sync such that net-zero quota changes already added to the transaction are no longer deemed necessary to be synced, and skipped. In this case references are taken for the qd and the slot from do_qc so those need to be put. The normal sequence of events for a normal non-zero quota change is as follows: gfs2_quota_change do_qc qd_hold slot_hold Later, when the changes are to be synced: gfs2_quota_sync qd_fish qd_check_sync gets qd ref via lockref_get_not_dead do_sync do_qc(QC_SYNC) qd_put lockref_put_or_lock qd_unlock qd_put lockref_put_or_lock In the net-zero change case, we add a check to qd_check_sync so it puts the qd and slot references acquired in gfs2_quota_change and skip the unneeded sync.

It's usually true, but it's still possible that the first interface is bound with another driver via a malformed descriptor. Then it may lead to a memory corruption, as spotted by syzkaller; imon driver accesses the data from drvdata as struct imon_context object although it's a completely different one that was assigned by another driver. This patch adds a sanity check -- whether the first interface is really bound with the imon driver or not -- for avoiding the problem above at the probe time.

If overflow is detected, CPU switches to `shadow_stack` temporarily before switching finally to per-cpu `overflow_stack`. If two CPUs/harts are racing and end up in over flowing kernel stack, one or both will end up corrupting each other state because `shadow_stack` is not per-cpu. This patch optimizes per-cpu overflow stack switch by directly picking per-cpu `overflow_stack` and gets rid of `shadow_stack`. Following are the changes in this patch - Defines an asm macro to obtain per-cpu symbols in destination register. - In entry.S, when overflow is detected, per-cpu overflow stack is located using per-cpu asm macro. Computing per-cpu symbol requires a temporary register. x31 is saved away into CSR_SCRATCH (CSR_SCRATCH is anyways zero since we're in kernel). Please see Links for additional relevant disccussion and alternative solution.

In the one shown below, for example, irq_count() is evaluated during kernel entry if !tick_nohz_full_cpu(smp_processor_id()). 0001ed0a <irq_enter_rcu>: 1ed0a: 4e56 0000 linkw %fp,#0 1ed0e: 200f movel %sp,%d0 1ed10: 0280 ffff e000 andil #-8192,%d0 1ed16: 2040 moveal %d0,%a0 1ed18: 2028 0008 movel %a0@(8),%d0 1ed1c: 0680 0001 0000 addil #65536,%d0 1ed22: 2140 0008 movel %d0,%a0@(8) 1ed26: 082a 0001 000f btst #1,%a2@(15) 1ed2c: 670c beqs 1ed3a <irq_enter_rcu+0x30> 1ed2e: 2028 0008 movel %a0@(8),%d0 1ed32: 2028 0008 movel %a0@(8),%d0 1ed36: 2028 0008 movel %a0@(8),%d0 1ed3a: 4e5e unlk %fp 1ed3c: 4e75 rts This patch doesn't prevent the pointless btst and beqs instructions above, but it does eliminate 2 of the 3 pointless move instructions here and elsewhere. On x86, preempt_count is per-cpu data and the problem does not arise presumably because the compiler is free to optimize more effectively. This patch was tested on m68k and x86. I was expecting no changes to object code for x86 and mostly that's what I saw. However, there were a few places where code generation was perturbed for some reason. The performance issue addressed here is minor on uniprocessor m68k. I got a 0.01% improvement from this patch for a simple "find /sys -false" benchmark. For architectures and workloads susceptible to cache line bounce the improvement is expected to be larger. The only SMP architecture I have is x86, and as x86 unaffected I have not done any further measurements.

In some special scenarios, when kernel frees the pipefs sb of the current client and immediately alloctes a new pipefs sb, rpc_remove_pipedir function would misjudge the existence of pipefs sb which is not the one it used to hold. As a result, the rpc_remove_pipedir would clean the released freed pipefs dentries. To fix this issue, rpc_remove_pipedir should check whether the current pipefs sb is consistent with the original pipefs sb.

The current default implementation only returns true for 16-bit c.ebreak if C extension is enabled. This can confuse uprobes if a 32-bit ebreak generates a trap exception from userspace: uprobes asks is_trap_insn() who says there is no trap, so uprobes assume a probe was there before but has been removed, and return to the trap instruction. This causes an infinite loop of entering and exiting trap handler. Instead of using the default implementation, implement this function speficially for riscv with checks for both ebreak and c.ebreak.

This has implications in three places: - when determining next instruction for non-jump instructions; - when determining next instruction for callback address ldimm64 instructions (in visit_func_call_insn()); - when checking for unreachable instructions, where second half of ldimm64 is expected to be unreachable; We take this also as an opportunity to report jump into the middle of ldimm64.

This situations doesn't necessarily mean that there were no instructions simulated in a state, but rather that we starting from the instruction, jumped around a bit, and then ended up at the same instruction before checkpointing or marking precision. To distinguish between these two possible situations, we need to consult jump history. If it's empty or contain a single record "bridging" parent state and first instruction of processed state, then we indeed backtracked all instructions in this state. But if history is not empty, we are definitely not done yet. Move this logic inside get_prev_insn_idx() to contain it more nicely.

This means that from CFG point of view there are definitely some back-edges. Original commit adjusted check_cfg() logic to not detect back-edges in control flow graph if they are resulting from conditional jumps, which the idea that subsequent full BPF verification process will determine whether such loops are bounded or not, and either accept or reject the BPF program. At least that's my reading of the intent. Unfortunately, the implementation of this idea doesn't work correctly in all possible situations. Conditional jump might not result in immediate back-edge, but just a few unconditional instructions later we can arrive at back-edge. In such situations check_cfg() would reject BPF program even in privileged mode, despite it might be bounded loop. Next patch adds one simple program demonstrating such scenario. To keep things simple, instead of trying to detect back edges in privileged mode, just assume every back edge is valid and let subsequent BPF verification prove or reject bounded loops. Note a few test changes. For unknown reason, we have a few tests that are specified to detect a back-edge in a privileged mode, but looking at their code it seems like the right outcome is passing check_cfg() and letting subsequent verification to make a decision about bounded or not bounded looping. Bounded recursion case is also interesting. The example should pass, as recursion is limited to just a few levels and so we never reach maximum number of nested frames and never exhaust maximum stack depth. But the way that max stack depth logic works today it falsely detects this as exceeding max nested frame count. This patch series doesn't attempt to fix this orthogonal problem, so we just adjust expected verifier failure.

SOCK_RCU_FREE was only tested at dismantle time. Commit 6acc9b432e67 ("bpf: Add helper to retrieve socket in BPF") started checking SOCK_RCU_FREE _after_ the lookup to infer whether the refcount has been taken care of.

Reduce stack size needed in ipvlan_process_v6_outbound() by moving the flowi6 struct used for the route lookup in an non inlined helper. ipvlan_route_v6_outbound() needs 120 bytes on the stack, immediately reclaimed. Also make sure ipvlan_process_v4_outbound() is not inlined. We might also have to lower MAX_NEST_DEV, because only syzbot uses setups with more than four stacked devices.

Unfortunately xen_send_IPI_one() is using notify_remote_via_irq() today, which is using irq_get_chip_data() via info_for_irq(). And irq_get_chip_data() in turn is using a maple-tree lookup requiring RCU. Avoid this problem by caching the ipi event channels in another percpu variable, allowing the use notify_remote_via_evtchn() in xen_send_IPI_one().

After imp reset command is executed, PF status changes to down, and PF will query link status and updates port information from firmware in a periodic scheduled task. However, there is a low probability that port information is updated when PF is down, and then PF link status changes to up. In this case, PF synchronizes incorrect rate and duplex mode to VF.

This size is calculated with TLV_SPACE() macro. It adds the size of struct tlv_desc and the length of TLV value passed as an argument, and aligns the result to a multiple of TLV_ALIGNTO, i.e., a multiple of 4 bytes. If the size of struct tlv_desc plus the length of TLV value is not aligned, the current implementation leaves the remaining bytes uninitialized. This is the cause of the above kernel-infoleak issue. This patch resolves this issue by clearing data up to an aligned size.

Limit to a sane upper bound of 64KB. No implementation I could find generates larger than 64KB frames. RFC 2823 mentions an upper bound of PPP over SDL of 64KB based on the 16-bit length field. Other protocols will be smaller, such as PPPoE (9KB jumbo frame) and PPPoA (18190 maximum CPCS-SDU size, RFC 2364). PPTP and L2TP encapsulate in IP.

In case the list isn't empty, the elements should be sorted by the time when eoi handling is to happen. Unfortunately a new element will never be queued at the start of the list, even if it has a handling time lower than all other list elements. Fix that by handling that case the same way as for an empty list.

In the following splat [1], the issue is that a lapbether device has been created on a bonding device without members. Then adding a non ARPHRD_ETHER member forced the bonding master to change its type. The fix is to make sure we call dev_close() in bond_setup_by_slave() so that the potential linked lapbether devices (or any other devices having assumptions on the physical device) are removed. A similar bug has been addressed in commit 40baec225765 ("bonding: fix panic on non-ARPHRD_ETHER enslave failure") [1] skbuff: skb_under_panic: text:ffff800089508810 len:44 put:40 head:ffff0000c78e7c00 data:ffff0000c78e7bea tail:0x16 end:0x140 dev:bond0 kernel BUG at net/core/skbuff.c:192 !

If we start sending bigger frames (after first bumping up the MTU on both interfaces sending and receiving the frames), truncated packets start to appear on the target such as in this tcpdump resulting from ping -s 1474: 23:34:17.241983 14:d6:4d:a8:3c:4f (oui Unknown) > bc:ae:c5:6b:a8:3d (oui Unknown), ethertype IPv4 (0x0800), length 1514: truncated-ip - 2 bytes missing! (tos 0x0, ttl 64, id 32653, offset 0, flags [DF], proto ICMP (1), length 1502) OpenWrt.lan > Fecusia: ICMP echo request, id 1672, seq 50, length 1482 If we bypass the hardware checksumming and provide a software fallback, everything starts working fine up to the max TX MTU of 2047 bytes, for example ping -s2000 192.168.1.2: 00:44:29.587598 bc:ae:c5:6b:a8:3d (oui Unknown) > 14:d6:4d:a8:3c:4f (oui Unknown), ethertype IPv4 (0x0800), length 2042: (tos 0x0, ttl 64, id 51828, offset 0, flags [none], proto ICMP (1), length 2028) Fecusia > OpenWrt.lan: ICMP echo reply, id 1683, seq 4, length 2008 The bit enabling to bypass hardware checksum (or any of the "TSS" bits) are undocumented in the hardware reference manual. The entire hardware checksum unit appears undocumented. The conclusion that we need to use the "bypass" bit was found by trial-and-error. Since no hardware checksum will happen, we slot in a software checksum fallback. Check for the condition where we need to compute checksum on the skb with either hardware or software using == CHECKSUM_PARTIAL instead of != CHECKSUM_NONE which is an incomplete check according to <linux/skbuff.h>. On the D-Link DIR-685 router this fixes a bug on the conduit interface to the RTL8366RB DSA switch: as the switch needs to add space for its tag it increases the MTU on the conduit interface to 1504 and that means that when the router sends packages of 1500 bytes these get an extra 4 bytes of DSA tag and the transfer fails because of the erroneous hardware checksumming, affecting such basic functionality as the LuCI web interface.

Reflect this in what we offer to Linux, cap the MTU at the TX max frame minus ethernet headers. We delete the code disabling the hardware checksum for large MTUs as netdev->mtu can no longer be larger than netdev->max_mtu meaning the if()-clause in gmac_fix_features() is never true.

Often this would cause strange crashes as the mutexes would be freed while they were being used. Looking at the code, there is a lifetime problem as the controlling thread that spawns the work allocates the "struct stress" structures that are passed to the workqueue threads. Then when the workqueue threads are finished, they free the stress struct that was passed to them. Unfortunately the workqueue work_struct node is in the stress struct. Which means the work_struct is freed before the work thread returns and while flush_workqueue is waiting. It seems like a better idea to have the controlling thread both allocate and free the stress structures, so that we can be sure we don't corrupt the workqueue by freeing the structure prematurely. So this patch reworks the test to do so, and with this change I no longer see the early flush_workqueue returns.

Such mismatch is an indicator that something really went wrong and only printing a warning message (and stack trace) is not enough to prevent a corruption. Allowing a transaction to commit with such an extent buffer will trigger an error if we ever try to read it from disk due to a generation mismatch with its parent generation. So abort the current transaction with -EUCLEAN if we notice a generation mismatch. For this we need to pass a transaction handle to btrfs_mark_buffer_dirty() which is always available except in test code, in which case we can pass NULL since it operates on dummy extent buffers and all test roots have a single node/leaf (root node at level 0).

As David Kaplan describes in his debugging of the issue, it is caused by a couple of KCSAN-generated constructors which aren't processed by objtool: "When KCSAN is enabled, GCC generates lots of constructor functions named _sub_I_00099_0 which call __tsan_init and then return. The returns in these are generally annotated normally by objtool and fixed up at runtime. But objtool runs on vmlinux.o and vmlinux.o does not include a couple of object files that are in vmlinux, like init/version-timestamp.o and .vmlinux.export.o, both of which contain _sub_I_00099_0 functions. As a result, the returns in these functions are not annotated, and the panic occurs when we call one of them in do_ctors and it uses the default return thunk. This difference can be seen by counting the number of these functions in the object files: $ objdump -d vmlinux.o|grep -c "<_sub_I_00099_0>:" 2601 $ objdump -d vmlinux|grep -c "<_sub_I_00099_0>:" 2603 If these functions are only run during kernel boot, there is no speculation concern." Fix it by disabling KCSAN on version-timestamp.o and .vmlinux.export.o so the extra functions don't get generated. KASAN and GCOV are already disabled for those files.

The maximum result of this subtraction is defined by the RCU_FANOUT_LEAF Kconfig option, which on 64-bit systems defaults to 16 (resulting in a maximum shift of 15), but which can be set up as high as 64 (resulting in a maximum shift of 63). A value of 31 can result in sign extension, resulting in 0xffffffff80000000 instead of the desired 0x80000000. A value of 32 or greater triggers undefined behavior per the C standard. This bug has not been known to cause issues because almost all kernels take the default CONFIG_RCU_FANOUT_LEAF=16. Furthermore, as long as a given compiler gives a deterministic non-zero result for 1<<N for N>=32, the code correctly invokes all SRCU callbacks, albeit wasting CPU time along the way. This commit therefore substitutes the correct 1UL for the buggy 1. Found by Linux Verification Center (linuxtesting.org) with SVACE.

However, after this [1] commit, UBSAN is triggered under many new scenarios that weren't detected before, such as in struct definitions with fixed-size trailing arrays used as flexible arrays. As a result, CONFIG_UBSAN_TRAP=y has become a very aggressive option to enable except for specific situations. `make kselftest-merge` applies CONFIG_UBSAN_TRAP=y to the kernel config for all selftests, which makes many of them fail because of system hangs during boot. This change removes the config option from the lkdtm kselftest and configures the ARRAY_BOUNDS test to look for UBSAN reports rather than relying on the calling process being killed.

The driver initially triggers a reset-to-zero of the two timers but this reset is only performed on the next rising clock. For the first timer this is ok - it will be in the next 60ns (16MHz clock). For the chained second timer this will only happen after the first timer overflows, i.e. after 2^16 clocks (~4ms with a 16MHz clock). So with other words the scheduler clock resets to 0 after the first 2^16 clock cycles. It looks like that the scheduler does not like this and behaves wrongly over its lifetime, e.g. some tasks are scheduled with a long delay. Why that is and if there are additional requirements for this behaviour has not been further analysed. There is a simple fix for resetting the second timer as well when the first timer is reset and this is to set the ATMEL_TC_ASWTRG_SET bit in the Channel Mode register (CMR) of the first timer. This will also rise the TIOA line (clock input of the second timer) when a software trigger respective SYNC is issued.

This operation is expected not to fail and therefore any similar attempt from other places shouldn't find any remaining callbacks to accelerate. Moreover accelerations performed beyond enqueue time are error prone because rcu_seq_snap() then may return the snapshot for a new grace period that is not going to be started. Remove these dangerous and needless accelerations and introduce instead assertions reporting leaking unaccelerated callbacks beyond enqueue time.

When it gets stuck temporarily, it usually gets released in a few seconds, and sometimes up to one or two minutes. If the CSD lock stays stuck for more than several minutes, it never seems to get unstuck, and gradually more and more things in the system end up also getting stuck. In the latter case, we should just give up, so the system can dump out a little more information about what went wrong, and, with panic_on_oops and a kdump kernel loaded, dump a whole bunch more information about what might have gone wrong. In addition, there is an smp.panic_on_ipistall kernel boot parameter that by default retains the old behavior, but when set enables the panic after the CSD lock has been stuck for more than the specified number of milliseconds, as in 300,000 for five minutes.

As a result the workqueue related locking scenario for a function A may be spuriously accounted as an inversion against the locking scenario of function B such as in the following model: long A(void *arg) { mutex_lock(&mutex); mutex_unlock(&mutex); } long B(void *arg) { } void launchA(void) { work_on_cpu(0, A, NULL); } void launchB(void) { mutex_lock(&mutex); work_on_cpu(1, B, NULL); mutex_unlock(&mutex); } launchA and launchB running concurrently have no chance to deadlock. However the above can be reported by lockdep as a possible locking inversion because the works containing A() and B() are treated as belonging to the same locking class.

The commit: 9391a3f9c7f1 ("[PATCH] x86_64: Clear more state when ignoring empty node in SRAT parsing") ... that introduced minimal size of a NUMA node does not explain why a node size cannot be less than 4MB and what boot failures this restriction might fix. Fixes have been submitted to the core MM code to tighten up the memory topologies it accepts and to not crash on weird input: mm: page_alloc: skip memoryless nodes entirely mm: memory_hotplug: drop memoryless node from fallback lists Andrew has accepted them into the -mm tree, but there are no stable SHA1's yet. This patch drops the limitation for minimal node size on x86: - which works around the crash without the fixes to the core MM. - makes x86 topologies less weird, - removes an arbitrary and undocumented limitation on NUMA topologies.

In the above scenario, a fragmented packet is received for self peer, for which rx_tid and rx_frags are not initialized in datapath. While handling this fragment, crash is observed as the rx_frag list is uninitialized and when we walk in ath12k_dp_rx_h_sort_frags, skb null leads to exception. To address this, before processing received fragments we check dp_setup_done flag is set to ensure that peer has completed its dp peer setup for fragment queue, else ignore processing the fragments.

The alx and atl1c drivers had RX overflow error which was why a custom allocator was created to avoid certain addresses. The simpler workaround then created for alx driver, but not for atl1c due to lack of tester. Instead of using a custom allocator, check the allocated skb address and use skb_reserve() to move away from problematic 0x...fc0 address. Tested on AR8131 on Acer 4540.

For one, any instruction following a bpf_throw call will never be marked as seen. Moreover, if a callchain ends up throwing, any instructions after the call instruction to the eventually throwing subprog in callers will also never be marked as seen. The tempting way to fix this would be to emit extra 'int3' instructions which bump the jited_len of a program, and ensure that during runtime when a program throws, we can discover its boundaries even if the call instruction to bpf_throw (or to subprogs that always throw) is emitted as the final instruction in the program. An example of such a program would be this: do_something(): ... r0 = 0 exit foo(): r1 = 0 call bpf_throw r0 = 0 exit bar(cond): if r1 != 0 goto pc+2 call do_something exit call foo r0 = 0 // Never seen by verifier exit // main(ctx): r1 = ... call bar r0 = 0 exit Here, if we do end up throwing, the stacktrace would be the following: bpf_throw foo bar main In bar, the final instruction emitted will be the call to foo, as such, the return address will be the subsequent instruction (which the JIT emits as int3 on x86). This will end up lying outside the jited_len of the program, thus, when unwinding, we will fail to discover the return address as belonging to any program and end up in a panic due to the unreliable stack unwinding of BPF programs that we never expect. To remedy this case, make bpf_prog_ksym_find treat IP == ksym.end as part of the BPF program, so that is_bpf_text_address returns true when such a case occurs, and we are able to unwind reliably when the final instruction ends up being a call instruction.

The problem was that aer_recover_queue() queues the pointer directly without copying the aer_capability_regs data. The pointer was to the ghes->estatus buffer, which could be reused before aer_recover_work_func() reads the data. To avoid this problem, allocate a new aer_capability_regs structure from the ghes_estatus_pool, copy the AER data from the ghes->estatus buffer into it, pass a pointer to the new struct to aer_recover_queue(), and free it after aer_recover_work_func() has processed it.

Or, worst case, on the separate line repeating instruction index. E.g., a nice and simple case would be: 2: (d5) if r0 s<= 0x0 goto pc+1 ; R0_w=0 But if there is some intervening extra output (e.g., precision backtracking log) involved, we are supposed to see the state after the precision backtrack log: 4: (75) if r0 s>= 0x0 goto pc+1 mark_precise: frame0: last_idx 4 first_idx 0 subseq_idx -1 mark_precise: frame0: regs=r0 stack= before 2: (d5) if r0 s<= 0x0 goto pc+1 mark_precise: frame0: regs=r0 stack= before 1: (b7) r0 = 0 6: R0_w=0 First off, note that in `6: R0_w=0` instruction index corresponds to the next instruction, not to the conditional jump instruction itself, which is wrong and we'll get to that. But besides that, the above is a happy case that does work today. Yet, if it so happens that precision backtracking had to traverse some of the parent states, this `6: R0_w=0` state output would be missing. This is due to a quirk of print_verifier_state() routine, which performs mark_verifier_state_clean(env) at the end. This marks all registers as "non-scratched", which means that subsequent logic to print *relevant* registers (that is, "scratched ones") fails and doesn't see anything relevant to print and skips the output altogether. print_verifier_state() is used both to print instruction context, but also to print an **entire** verifier state indiscriminately, e.g., during precision backtracking (and in a few other situations, like during entering or exiting subprogram). Which means if we have to print entire parent state before getting to printing instruction context state, instruction context is marked as clean and is omitted. Long story short, this is definitely not intentional. So we fix this behavior in this patch by teaching print_verifier_state() to clear scratch state only if it was used to print instruction state, not the parent/callback state. This is determined by print_all option, so if it's not set, we don't clear scratch state. This fixes missing instruction state for these cases. As for the mismatched instruction index, we fix that by making sure we call print_insn_state() early inside check_cond_jmp_op() before we adjusted insn_idx based on jump branch taken logic. And with that we get desired correct information: 9: (16) if w4 == 0x1 goto pc+9 mark_precise: frame0: last_idx 9 first_idx 9 subseq_idx -1 mark_precise: frame0: parent state regs=r4 stack=: R2_w=1944 R4_rw=P1 R10=fp0 mark_precise: frame0: last_idx 8 first_idx 0 subseq_idx 9 mark_precise: frame0: regs=r4 stack= before 8: (66) if w4 s> 0x3 goto pc+5 mark_precise: frame0: regs=r4 stack= before 7: (b7) r4 = 1 9: R4=1 Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Acked-by: John Fastabend <john.fastabend@gmail.com> Acked-by: Eduard Zingerman <eddyz87@gmail.com> Link: https://lore.kernel.org/bpf/20231011223728.3188086-6-andrii@kernel.org Signed-off-by: Sasha Levin <sashal@kernel.org> Signed-off-by: Zheng Zengkai <zhengzengkai@huawei.com> --- kernel/bpf/verifier.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/kernel/bpf/verifier.c b/kernel/bpf/verifier.c index 82c9e5c47031..6542685d6772 100644 --- a/kernel/bpf/verifier.c +++ b/kernel/bpf/verifier.c @@ -1515,7 +1515,8 @@ static void print_verifier_state(struct bpf_verifier_env *env, if (state->in_async_callback_fn) verbose(env, " async_cb"); verbose(env, "\n"); - mark_verifier_state_clean(env); + if (!print_all) + mark_verifier_state_clean(env); } static inline u32 vlog_alignment(u32 pos) @@ -14139,6 +14140,8 @@ static int check_cond_jmp_op(struct bpf_verifier_env *env, !sanitize_speculative_path(env, insn, *insn_idx + 1, *insn_idx)) return -EFAULT; + if (env->log.level & BPF_LOG_LEVEL) + print_insn_state(env, this_branch->frame[this_branch->curframe]); *insn_idx += insn->off; return 0; } else if (pred == 0) { @@ -14151,6 +14154,8 @@ static int check_cond_jmp_op(struct bpf_verifier_env *env, *insn_idx + insn->off + 1, *insn_idx)) return -EFAULT; + if (env->log.level & BPF_LOG_LEVEL) + print_insn_state(env, this_branch->frame[this_branch->curframe]); return 0; } -- 2.20.1

After releasing an object using hci_conn_del_sysfs in the hci_conn_cleanup function, releasing the same object again using the hci_dev_put and hci_conn_put functions causes a double free. Here's a simplified flow: hci_conn_del_sysfs: hci_dev_put put_device kobject_put kref_put kobject_release kobject_cleanup kfree_const kfree(name) hci_dev_put: ... kfree(name) hci_conn_put: put_device ... kfree(name) This patch drop the hci_dev_put and hci_conn_put function call in hci_conn_cleanup function, because the object is freed in hci_conn_del_sysfs function. This patch also fixes the refcounting in hci_conn_add_sysfs() and hci_conn_del_sysfs() to take into account device_add() failures. This fixes CVE-2023-28464.

At the ACPI level an _AEI event-handler is connected which sets an ACPI variable to 1 on both edges. This variable can be polled + cleared to 0 using WMI. Since the variable is set on both edges the WMI interface is pretty useless even when polling. So instead of writing a custom WMI driver for this the x86-android-tablets code instantiates a gpio-keys platform device for the "dolby" button. Add an ignore_interrupt quirk for INT33FC:00 pin 3 on the Peaq C1010, so that it is not seen as busy when the gpio-keys driver requests it. Note this replaces a hack in x86-android-tablets where it would call acpi_gpiochip_free_interrupts() on the INT33FC:00 GPIO controller. acpi_gpiochip_free_interrupts() is considered private (internal) gpiolib API so x86-android-tablets should stop using it.

For instance: pci@0,0 { #address-cells = <0x03>; #size-cells = <0x02>; device_type = "pci"; compatible = "pci11ab,100", "pciclass,060400", "pciclass,0604"; ranges = <0x82000000 0x00 0xe8000000 0x82000000 0x00 0xe8000000 0x00 0x4400000>; ... dev@0,0 { #address-cells = <0x03>; #size-cells = <0x02>; compatible = "pci1055,9660", "pciclass,020000", "pciclass,0200"; /* Translations for BAR0 to BAR5 */ ranges = <0x00 0x00 0x00 0x82010000 0x00 0xe8000000 0x00 0x2000000 0x01 0x00 0x00 0x82010000 0x00 0xea000000 0x00 0x1000000 0x02 0x00 0x00 0x82010000 0x00 0xeb000000 0x00 0x800000 0x03 0x00 0x00 0x82010000 0x00 0xeb800000 0x00 0x800000 0x04 0x00 0x00 0x82010000 0x00 0xec000000 0x00 0x20000 0x05 0x00 0x00 0x82010000 0x00 0xec020000 0x00 0x2000>; ... pci-ep-bus@0 { #address-cells = <0x01>; #size-cells = <0x01>; compatible = "simple-bus"; /* Translate 0xe2000000 to BAR0 and 0xe0000000 to BAR1 */ ranges = <0xe2000000 0x00 0x00 0x00 0x2000000 0xe0000000 0x01 0x00 0x00 0x1000000>; ... }; }; }; During the translation process, the "default-flags" map() function is used to select the matching item in the ranges table and determine the address offset from this matching item. This map() function simply calls of_read_number() and when address-size is greater than 2, the map() function skips the extra high address part (ie part over 64bit). This lead to a wrong matching item and a wrong offset computation. Also during the translation itself, the extra high part related to the parent address is not present in the translated address. Fix the "default-flags" map() and translate() in order to take into account the child extra high address part in map() and the parent extra high address part in translate() and so having a correct address translation for ranges patterns such as the one given in the example above.

On the currently problemtic machine (HP Omni 120) EDID reports the following mode: "1600x900": 60 108000 1600 1780 1860 1800 900 910 913 1000 0x40 0x5 which is then "corrected" to have htotal=1861 by the current drm_edid.c code. The fixup code was originally added in commit 7064fef56369 ("drm: work around EDIDs with bad htotal/vtotal values"). Googling around we end up in https://bugs.launchpad.net/ubuntu/hardy/+source/xserver-xorg-video-intel/+bu... where we find an EDID for a Dell Studio 15, which reports: (II) VESA(0): clock: 65.0 MHz Image Size: 331 x 207 mm (II) VESA(0): h_active: 1280 h_sync: 1328 h_sync_end 1360 h_blank_end 1337 h_border: 0 (II) VESA(0): v_active: 800 v_sync: 803 v_sync_end 809 v_blanking: 810 v_border: 0 Note that if we use the hblank size (as opposed of the hsync_end) from the DTD to determine htotal we get exactly 60Hz refresh rate in both cases, whereas using hsync_end to determine htotal we get a slightly lower refresh rates. This makes me believe the using the hblank size is what was intended even in those cases. Also note that in case of the HP Onmi 120 the VBIOS boots with these: crtc timings: 108000 1600 1780 1860 1800 900 910 913 1000, type: 0x40 flags: 0x5 ie. it just blindly stuffs the bogus hsync_end and htotal from the DTD into the transcoder timing registers, and the display works. I believe the (at least more modern) hardware will automagically terminate the hsync pulse when the timing generator reaches htotal, which again points that we should use the hblank size to determine htotal. Unfortunatley the old bug reports for the Dell machines are extremely lacking in useful details so we have no idea what kind of timings the VBIOS programmed into the hardware :( Let's just flip this quirk around and reduce the length of the sync pulse instead of extending the blanking period. This at least seems to be the correct thing to do on more modern hardware. And if any issues crop up on older hardware we need to debug them properly. v2: Add debug message breadcrumbs (Jani) Reviewed-by: Jani Nikula <jani.nikula@intel.com> Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/8895 Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230920211934.14920-1-ville.s...

Sometimes the checks are done manually; sometimes the array size is calculated with array_size() and sometimes by calculating n * size directly in code. Introduce wrappers for arrays for memdup_user() and vmemdup_user() to provide a standardized and safe way for duplicating user arrays. This is both for new code as well as replacing usage of (v)memdup_user() in existing code that uses, e.g., n * size to calculate array sizes.

Skip the validity check. For the most part (*), the EDIDs returned by drm_get_edid() will be valid anyway, and there's the CTS workaround to get the checksum for completely invalid EDIDs. See commit 7948fe12d47a ("drm/msm/dp: return correct edid checksum after corrupted edid checksum read"). This lets us remove one user of drm_edid_block_valid() with hopes the function can be removed altogether in the future. (*) drm_get_edid() ignores checksum errors on CTA extensions.

There also needs to be a delay after enabling the supplies and before deasserting the reset. The datasheet specifies 1ms after the supplies reach the required voltage. Use 10-20ms to also give the power supplies some time to reach the required voltage, too. This fixes intermittent panel initialization failures and screen corruption during resume from sleep on panel xingbangda,xbd599 (e.g. used in PinePhone).

This is required because the SoC uses 48b address sizes and this mismatch would lead to smmu context faults [1] because the usb generates 40b addresses while the smmu page tables are populated with 48b wide addresses.

The PCI specification provides two registers to store a vendor-specific SSID that can be read by drivers to uniquely identify a particular "soundcard". This is defined in the PCI specification to distinguish products that use the same silicon (and therefore have the same silicon ID) so that product-specific differences can be applied. PCI only defines 0xFFFF as an invalid value. 0x0000 is not defined as invalid. So the usual pattern of zero-filling the struct and then assuming a zero value unset will not work. A flag is included to indicate when the SSID information has been filled in. Unlike DMI information, which has a free-format entirely up to the vendor, the PCI SSID has a strictly defined format and a registry of vendor IDs. It is usual in Windows drivers that the SSID is used as the sole identifier of the specific end-product and the Windows driver contains tables mapping that to information about the hardware setup, rather than using ACPI properties. This SSID is important information for ASoC components that need to apply hardware-specific configuration on PCI-based systems. As the SSID is a generic part of the PCI specification and is treated as identifying the "soundcard", it is reasonable to include this information in struct snd_soc_card, instead of components inventing their own custom ways to pass this information around.

This allows the machine driver to use the SSID to uniquely identify the specific hardware configuration and apply any platform-specific configuration. struct snd_sof_pdata is passed around inside the SOF code, but it then passes configuration information to the machine driver through struct snd_soc_acpi_mach and struct snd_soc_acpi_mach_params. So SSID information has been added to both snd_sof_pdata and snd_soc_acpi_mach_params. PCI does not define 0x0000 as an invalid value so we can't use zero to indicate that the struct member was not written. Instead a flag is included to indicate that a value has been written to the subsystem_vendor and subsystem_device members. sof_pci_probe() creates the struct snd_sof_pdata. It is passed a struct pci_dev so it can fill in the SSID value. sof_machine_check() finds the appropriate struct snd_soc_acpi_mach. It copies the SSID information across to the struct snd_soc_acpi_mach_params. This done before calling any custom set_mach_params() so that it could be used by the set_mach_params() callback to apply variant params. The machine driver receives the struct snd_soc_acpi_mach as its platform_data.

On PCI-based systems the PCI SSID is used to uniquely identify the specific sound hardware. This is the standard mechanism for x86 systems and is the way to get a unique system identifier for systems that use the CS35L56 on SoundWire. For non-SoundWire systems there is no Windows equivalent of the ASoC driver in I2C/SPI mode. These would be: 1. HDA systems, which are handled by the HDA subsystem. 2. Linux-specific systems. 3. Composite devices where the cs35l56 is not present in ACPI and is configured using software nodes. Case 2 can use the firmware-uid property, though the PCI SSID is supported as an alternative, as it is the standard PCI mechanism.

In normal case, aead_request_complete() will be called in pcrypt_aead_serial and the return err is 0 for padata_do_parallel. But, when pinst->flags is PADATA_RESET, the return err is -EBUSY for padata_do_parallel, and it won't call aead_request_complete(). Therefore, test_aead_vec_cfg will hung at wait_for_completion(&wait->completion), which will cause hungtask. The problem comes as following: (padata_do_parallel) | rcu_read_lock_bh(); | err = -EINVAL; | (padata_replace) | pinst->flags |= PADATA_RESET; err = -EBUSY | if (pinst->flags & PADATA_RESET) | rcu_read_unlock_bh() | return err In order to resolve the problem, we replace the return err -EBUSY with -EAGAIN, which means parallel_data is changing, and the caller should call it again. v3: remove retry and just change the return err. v2: introduce padata_try_do_parallel() in pcrypt_aead_encrypt and pcrypt_aead_decrypt to solve the hungtask.

In the unlikely event that this happens, the code asserts a BUG_ON, and in the case that the kernel is not configured to crash on panic returns a junk event pointer from the empty event list causing things to spiral from there. This BUG_ON is a historical artifact of the ibmvfc driver first being upstreamed, and it is well known now that the use of BUG_ON is bad practice except in the most unrecoverable scenario. There is nothing about this scenario that prevents the driver from recovering and carrying on. Remove the BUG_ON in question from ibmvfc_get_event() and return a NULL pointer in the case of an empty event pool. Update all call sites to ibmvfc_get_event() to check for a NULL pointer and perfrom the appropriate failure or recovery action.

Commit 3cb5ff0220e3 ("HID: lenovo: Hide middle-button press until release") workarounds last issue but it's impossible to workaround scrolling-related issues without firmware modification. Likely, Dennis Schneider has reverse engineered the firmware and provided an instruction on how to patch it [1]. However, aforementioned workaround prevents userspace (libinput) from knowing exact moment when middle button has been pressed down and performing "On-Button scrolling". This commit detects correctly-behaving patched firmware if cursor movement events has been received during middle button being pressed and stops applying workaround for this device.

Seeing there is a max-link-speed setup method defined in the DW PCIe core driver it would be good to have a similar function for the link width setup. That's why we need to define a dedicated function first from already implemented but incomplete link-width setting up code.

The intention is to wait for the device to retry the wakeup event if the USB3 PORTSC doesn't reflect the RESUME link status by the time it is checked. As per the USB3 specification: tU3WakeupRetryDelay ("Table 7-12. LTSSM State Transition Timeouts") This would allow the XHCI resume sequence to determine if the root hub needs to be also resumed. However, in case there is no device connected, or if there is only a HSUSB device connected, this delay would still affect the overall resume timing. Since this delay is solely for detecting U3 wake events (USB3 specific) then ignore this delay for the disconnected case and the HSUSB connected only case.

Nevertheless, the gadget pointer could change during bind/unbind cycles due to various conditions, including the unloading/loading of the UDC device driver or the detachment/reconnection of an OTG-capable USB hub device. This patch relocates the gether_set_gadget() function out from ncm_opts->bound condition check, ensuring that the correct gadget is assigned during each bind request.

If the timing is right, function do_qc can add pending quota changes to a transaction, then later, another call to do_qc can negate those changes, resulting in a net gain of 0. The quota_change information is recorded in the qc buffer (and qd element of the inode as well). The buffer is added to the transaction by the first call to do_qc, but a subsequent call changes the value from non-zero back to zero. At that point it's too late to remove the buffer_head from the transaction. Later, when the quota sync code is called, the zero-change qd element is discovered and flagged as an assert warning. If the fs is mounted with errors=panic, the kernel will panic. This is usually seen when files are truncated and the quota changes are negated by punch_hole/truncate which uses gfs2_quota_hold and gfs2_quota_unhold rather than block allocations that use gfs2_quota_lock and gfs2_quota_unlock which automatically do quota sync. This patch solves the problem by adding a check to qd_check_sync such that net-zero quota changes already added to the transaction are no longer deemed necessary to be synced, and skipped. In this case references are taken for the qd and the slot from do_qc so those need to be put. The normal sequence of events for a normal non-zero quota change is as follows: gfs2_quota_change do_qc qd_hold slot_hold Later, when the changes are to be synced: gfs2_quota_sync qd_fish qd_check_sync gets qd ref via lockref_get_not_dead do_sync do_qc(QC_SYNC) qd_put lockref_put_or_lock qd_unlock qd_put lockref_put_or_lock In the net-zero change case, we add a check to qd_check_sync so it puts the qd and slot references acquired in gfs2_quota_change and skip the unneeded sync.

It's usually true, but it's still possible that the first interface is bound with another driver via a malformed descriptor. Then it may lead to a memory corruption, as spotted by syzkaller; imon driver accesses the data from drvdata as struct imon_context object although it's a completely different one that was assigned by another driver. This patch adds a sanity check -- whether the first interface is really bound with the imon driver or not -- for avoiding the problem above at the probe time.

If overflow is detected, CPU switches to `shadow_stack` temporarily before switching finally to per-cpu `overflow_stack`. If two CPUs/harts are racing and end up in over flowing kernel stack, one or both will end up corrupting each other state because `shadow_stack` is not per-cpu. This patch optimizes per-cpu overflow stack switch by directly picking per-cpu `overflow_stack` and gets rid of `shadow_stack`. Following are the changes in this patch - Defines an asm macro to obtain per-cpu symbols in destination register. - In entry.S, when overflow is detected, per-cpu overflow stack is located using per-cpu asm macro. Computing per-cpu symbol requires a temporary register. x31 is saved away into CSR_SCRATCH (CSR_SCRATCH is anyways zero since we're in kernel). Please see Links for additional relevant disccussion and alternative solution.

This was problematic when sending mgmt frames in eSR mode, as we don't know what link this frame will be sent on (This is decided by the FW), so we don't know what is the lowest rate. Fix this by not setting the rate in tx cmd and rely on FW to choose the right one. Set rate only for injected frames with fixed rate, or when no sta is given.

Repeated invocations in macros like irq_count() produce repeated loads. These redundant instructions appear in various fast paths. In the one shown below, for example, irq_count() is evaluated during kernel entry if !tick_nohz_full_cpu(smp_processor_id()). 0001ed0a <irq_enter_rcu>: 1ed0a: 4e56 0000 linkw %fp,#0 1ed0e: 200f movel %sp,%d0 1ed10: 0280 ffff e000 andil #-8192,%d0 1ed16: 2040 moveal %d0,%a0 1ed18: 2028 0008 movel %a0@(8),%d0 1ed1c: 0680 0001 0000 addil #65536,%d0 1ed22: 2140 0008 movel %d0,%a0@(8) 1ed26: 082a 0001 000f btst #1,%a2@(15) 1ed2c: 670c beqs 1ed3a <irq_enter_rcu+0x30> 1ed2e: 2028 0008 movel %a0@(8),%d0 1ed32: 2028 0008 movel %a0@(8),%d0 1ed36: 2028 0008 movel %a0@(8),%d0 1ed3a: 4e5e unlk %fp 1ed3c: 4e75 rts This patch doesn't prevent the pointless btst and beqs instructions above, but it does eliminate 2 of the 3 pointless move instructions here and elsewhere. On x86, preempt_count is per-cpu data and the problem does not arise presumably because the compiler is free to optimize more effectively. This patch was tested on m68k and x86. I was expecting no changes to object code for x86 and mostly that's what I saw. However, there were a few places where code generation was perturbed for some reason. The performance issue addressed here is minor on uniprocessor m68k. I got a 0.01% improvement from this patch for a simple "find /sys -false" benchmark. For architectures and workloads susceptible to cache line bounce the improvement is expected to be larger. The only SMP architecture I have is x86, and as x86 unaffected I have not done any further measurements.

In some special scenarios, when kernel frees the pipefs sb of the current client and immediately alloctes a new pipefs sb, rpc_remove_pipedir function would misjudge the existence of pipefs sb which is not the one it used to hold. As a result, the rpc_remove_pipedir would clean the released freed pipefs dentries. To fix this issue, rpc_remove_pipedir should check whether the current pipefs sb is consistent with the original pipefs sb.

The current default implementation only returns true for 16-bit c.ebreak if C extension is enabled. This can confuse uprobes if a 32-bit ebreak generates a trap exception from userspace: uprobes asks is_trap_insn() who says there is no trap, so uprobes assume a probe was there before but has been removed, and return to the trap instruction. This causes an infinite loop of entering and exiting trap handler. Instead of using the default implementation, implement this function speficially for riscv with checks for both ebreak and c.ebreak.

This has implications in three places: - when determining next instruction for non-jump instructions; - when determining next instruction for callback address ldimm64 instructions (in visit_func_call_insn()); - when checking for unreachable instructions, where second half of ldimm64 is expected to be unreachable; We take this also as an opportunity to report jump into the middle of ldimm64. And adjust few test_verifier tests accordingly.

This situations doesn't necessarily mean that there were no instructions simulated in a state, but rather that we starting from the instruction, jumped around a bit, and then ended up at the same instruction before checkpointing or marking precision. To distinguish between these two possible situations, we need to consult jump history. If it's empty or contain a single record "bridging" parent state and first instruction of processed state, then we indeed backtracked all instructions in this state. But if history is not empty, we are definitely not done yet. Move this logic inside get_prev_insn_idx() to contain it more nicely. Use -ENOENT return code to denote "we are out of instructions" situation. This bug was exposed by verifier_loop1.c's bounded_recursion subtest, once the next fix in this patch set is applied.

This means that from CFG point of view there are definitely some back-edges. Original commit adjusted check_cfg() logic to not detect back-edges in control flow graph if they are resulting from conditional jumps, which the idea that subsequent full BPF verification process will determine whether such loops are bounded or not, and either accept or reject the BPF program. At least that's my reading of the intent. Unfortunately, the implementation of this idea doesn't work correctly in all possible situations. Conditional jump might not result in immediate back-edge, but just a few unconditional instructions later we can arrive at back-edge. In such situations check_cfg() would reject BPF program even in privileged mode, despite it might be bounded loop. Next patch adds one simple program demonstrating such scenario. To keep things simple, instead of trying to detect back edges in privileged mode, just assume every back edge is valid and let subsequent BPF verification prove or reject bounded loops. Note a few test changes. For unknown reason, we have a few tests that are specified to detect a back-edge in a privileged mode, but looking at their code it seems like the right outcome is passing check_cfg() and letting subsequent verification to make a decision about bounded or not bounded looping. Bounded recursion case is also interesting. The example should pass, as recursion is limited to just a few levels and so we never reach maximum number of nested frames and never exhaust maximum stack depth. But the way that max stack depth logic works today it falsely detects this as exceeding max nested frame count. This patch series doesn't attempt to fix this orthogonal problem, so we just adjust expected verifier failure.

Unfortunately xen_send_IPI_one() is using notify_remote_via_irq() today, which is using irq_get_chip_data() via info_for_irq(). And irq_get_chip_data() in turn is using a maple-tree lookup requiring RCU. Avoid this problem by caching the ipi event channels in another percpu variable, allowing the use notify_remote_via_evtchn() in xen_send_IPI_one().

We think firmware watchdog initialization is completed before VF clear the interrupt source. However, firmware initialization may not complete early. So VF will receive multiple reset interrupts and fail to reset. So we add delay before VF interrupt source and 5 ms delay is enough to avoid second reset interrupt.

After imp reset command is executed, PF status changes to down, and PF will query link status and updates port information from firmware in a periodic scheduled task. However, there is a low probability that port information is updated when PF is down, and then PF link status changes to up. In this case, PF synchronizes incorrect rate and duplex mode to VF. This patch fixes it by updating port information before PF synchronizes the rate and duplex to the VF when PF changes to up.

This size is calculated with TLV_SPACE() macro. It adds the size of struct tlv_desc and the length of TLV value passed as an argument, and aligns the result to a multiple of TLV_ALIGNTO, i.e., a multiple of 4 bytes. If the size of struct tlv_desc plus the length of TLV value is not aligned, the current implementation leaves the remaining bytes uninitialized. This is the cause of the above kernel-infoleak issue. This patch resolves this issue by clearing data up to an aligned size.

The current implementation leads to the following crash calling ethstats on a port that is down or when calling it at the wrong moment: ble to handle kernel NULL pointer dereference at virtual address 00000070 [00000070] *pgd=00000000 Internal error: Oops: 5 [#1] SMP ARM Hardware name: Marvell Armada 380/385 (Device Tree) PC is at page_pool_get_stats+0x18/0x1cc LR is at mvneta_ethtool_get_stats+0xa0/0xe0 [mvneta] pc : [<c0b413cc>] lr : [<bf0a98d8>] psr: a0000013 sp : f1439d48 ip : f1439dc0 fp : 0000001d r10: 00000100 r9 : c4816b80 r8 : f0d75150 r7 : bf0b400c r6 : c238f000 r5 : 00000000 r4 : f1439d68 r3 : c2091040 r2 : ffffffd8 r1 : f1439d68 r0 : 00000000 Flags: NzCv IRQs on FIQs on Mode SVC_32 ISA ARM Segment none Control: 10c5387d Table: 066b004a DAC: 00000051 Register r0 information: NULL pointer Register r1 information: 2-page vmalloc region starting at 0xf1438000 allocated at kernel_clone+0x9c/0x390 Register r2 information: non-paged memory Register r3 information: slab kmalloc-2k start c2091000 pointer offset 64 size 2048 Register r4 information: 2-page vmalloc region starting at 0xf1438000 allocated at kernel_clone+0x9c/0x390 Register r5 information: NULL pointer Register r6 information: slab kmalloc-cg-4k start c238f000 pointer offset 0 size 4096 Register r7 information: 15-page vmalloc region starting at 0xbf0a8000 allocated at load_module+0xa30/0x219c Register r8 information: 1-page vmalloc region starting at 0xf0d75000 allocated at ethtool_get_stats+0x138/0x208 Register r9 information: slab task_struct start c4816b80 pointer offset 0 Register r10 information: non-paged memory Register r11 information: non-paged memory Register r12 information: 2-page vmalloc region starting at 0xf1438000 allocated at kernel_clone+0x9c/0x390 Process snmpd (pid: 733, stack limit = 0x38de3a88) Stack: (0xf1439d48 to 0xf143a000) 9d40: 000000c0 00000001 c238f000 bf0b400c f0d75150 c4816b80 9d60: 00000100 bf0a98d8 00000000 00000000 00000000 00000000 00000000 00000000 9d80: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 9da0: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 9dc0: 00000dc0 5335509c 00000035 c238f000 bf0b2214 01067f50 f0d75000 c0b9b9c8 9de0: 0000001d 00000035 c2212094 5335509c c4816b80 c238f000 c5ad6e00 01067f50 9e00: c1b0be80 c4816b80 00014813 c0b9d7f0 00000000 00000000 0000001d 0000001d 9e20: 00000000 00001200 00000000 00000000 c216ed90 c73943b8 00000000 00000000 9e40: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 9e60: 00000000 c0ad9034 00000000 00000000 00000000 00000000 00000000 00000000 9e80: 00000000 00000000 00000000 5335509c c1b0be80 f1439ee4 00008946 c1b0be80 9ea0: 01067f50 f1439ee3 00000000 00000046 b6d77ae0 c0b383f0 00008946 becc83e8 9ec0: c1b0be80 00000051 0000000b c68ca480 c7172d00 c0ad8ff0 f1439ee3 cf600e40 9ee0: 01600e40 32687465 00000000 00000000 00000000 01067f50 00000000 00000000 9f00: 00000000 5335509c 00008946 00008946 00000000 c68ca480 becc83e8 c05e2de0 9f20: f1439fb0 c03002f0 00000006 5ac3c35a c4816b80 00000006 b6d77ae0 c030caf0 9f40: c4817350 00000014 f1439e1c 0000000c 00000000 00000051 01000000 00000014 9f60: 00003fec f1439edc 00000001 c0372abc b6d77ae0 c0372abc cf600e40 5335509c 9f80: c21e6800 01015c9c 0000000b 00008946 00000036 c03002f0 c4816b80 00000036 9fa0: b6d77ae0 c03000c0 01015c9c 0000000b 0000000b 00008946 becc83e8 00000000 9fc0: 01015c9c 0000000b 00008946 00000036 00000035 010678a0 b6d797ec b6d77ae0 9fe0: b6dbf738 becc838c b6d186d7 b6baa858 40000030 0000000b 00000000 00000000 page_pool_get_stats from mvneta_ethtool_get_stats+0xa0/0xe0 [mvneta] mvneta_ethtool_get_stats [mvneta] from ethtool_get_stats+0x154/0x208 ethtool_get_stats from dev_ethtool+0xf48/0x2480 dev_ethtool from dev_ioctl+0x538/0x63c dev_ioctl from sock_ioctl+0x49c/0x53c sock_ioctl from sys_ioctl+0x134/0xbd8 sys_ioctl from ret_fast_syscall+0x0/0x1c Exception stack(0xf1439fa8 to 0xf1439ff0) 9fa0: 01015c9c 0000000b 0000000b 00008946 becc83e8 00000000 9fc0: 01015c9c 0000000b 00008946 00000036 00000035 010678a0 b6d797ec b6d77ae0 9fe0: b6dbf738 becc838c b6d186d7 b6baa858 Code: e28dd004 e1a05000 e2514000 0a00006a (e5902070) This commit adds the proper checks before calling page_pool_get_stats.

Limit to a sane upper bound of 64KB. No implementation I could find generates larger than 64KB frames. RFC 2823 mentions an upper bound of PPP over SDL of 64KB based on the 16-bit length field. Other protocols will be smaller, such as PPPoE (9KB jumbo frame) and PPPoA (18190 maximum CPCS-SDU size, RFC 2364). PPTP and L2TP encapsulate in IP.

In case the list isn't empty, the elements should be sorted by the time when eoi handling is to happen. Unfortunately a new element will never be queued at the start of the list, even if it has a handling time lower than all other list elements. Fix that by handling that case the same way as for an empty list.

In the following splat [1], the issue is that a lapbether device has been created on a bonding device without members. Then adding a non ARPHRD_ETHER member forced the bonding master to change its type. The fix is to make sure we call dev_close() in bond_setup_by_slave() so that the potential linked lapbether devices (or any other devices having assumptions on the physical device) are removed. A similar bug has been addressed in commit 40baec225765 ("bonding: fix panic on non-ARPHRD_ETHER enslave failure") [1] skbuff: skb_under_panic: text:ffff800089508810 len:44 put:40 head:ffff0000c78e7c00 data:ffff0000c78e7bea tail:0x16 end:0x140 dev:bond0 kernel BUG at net/core/skbuff.c:192 !

If we start sending bigger frames (after first bumping up the MTU on both interfaces sending and receiving the frames), truncated packets start to appear on the target such as in this tcpdump resulting from ping -s 1474: 23:34:17.241983 14:d6:4d:a8:3c:4f (oui Unknown) > bc:ae:c5:6b:a8:3d (oui Unknown), ethertype IPv4 (0x0800), length 1514: truncated-ip - 2 bytes missing!

The entire hardware checksum unit appears undocumented. The conclusion that we need to use the "bypass" bit was found by trial-and-error. Since no hardware checksum will happen, we slot in a software checksum fallback. Check for the condition where we need to compute checksum on the skb with either hardware or software using == CHECKSUM_PARTIAL instead of != CHECKSUM_NONE which is an incomplete check according to <linux/skbuff.h>. On the D-Link DIR-685 router this fixes a bug on the conduit interface to the RTL8366RB DSA switch: as the switch needs to add space for its tag it increases the MTU on the conduit interface to 1504 and that means that when the router sends packages of 1500 bytes these get an extra 4 bytes of DSA tag and the transfer fails because of the erroneous hardware checksumming, affecting such basic functionality as the LuCI web interface.

Reflect this in what we offer to Linux, cap the MTU at the TX max frame minus ethernet headers. We delete the code disabling the hardware checksum for large MTUs as netdev->mtu can no longer be larger than netdev->max_mtu meaning the if()-clause in gmac_fix_features() is never true.

On each iteration we are writing 8 bytes. But dst[] is an array of u32 so each element only has space for 4 bytes. That means that every iteration overwrites part of the previous element. I spotted this bug while reviewing commit caf3ef7468f7 ("netfilter: nf_tables: prevent OOB access in nft_byteorder_eval") which is a related issue.

For that case, we end up not printing the current CPU and PID info. Rather than rely on this lock, just print the pid we already stored in the io_sq_data struct, and ensure we update the current CPU every time we've slept or potentially rescheduled. The latter won't potentially be 100% accurate, but that wasn't the case before either as the task can get migrated at any time unless it has been pinned at creation time. We retain keeping the io_sq_data dereference inside the ctx->uring_lock, as it has always been, as destruction of the thread and data happen below that. We could make this RCU safe, but there's little point in doing that. With this, we always print the last valid information we had, rather than have spurious outputs with missing information.

However, on IRQ release, the said cpumask is not updated by clearing the CPU from the mask to allow future IRQ request, causing the following error when a SF is reloaded after it has utilized all CPUs for its IRQs: mlx5_irq_affinity_request:135:(pid 306010): Didn't find a matching IRQ. err = -28 Thus, when releasing an IRQ, clear its mapped CPU from the used CPUs mask, to prevent the case described above. While at it, move the used cpumask update to the EQ layer as it is more fitting and preserves symmetricity of the IRQ request/release API.

However, e->encap_header is already set to the previously freed encap_header before mlx5_packet_reformat_alloc().

In the mlx5e_sq_xmit_wqe context, this would lead to either overrunning the device CQ or exceeding the expected software buffer size in the device CQ if the device CQ size was greater than the software buffer size. Update the relevant software counter only after updating the device CQ consumer index in the port timestamping napi_poll context.

However, prior to this patch, a flower filter with a helper in the ct action can be successfully set into the HW, for example (eth1 is a bnxt NIC): # tc qdisc add dev eth1 ingress_block 22 ingress # tc filter add block 22 proto ip flower skip_sw ip_proto tcp \ dst_port 21 ct_state -trk action ct helper ipv4-tcp-ftp # tc filter show dev eth1 ingress filter block 22 protocol ip pref 49152 flower chain 0 handle 0x1 eth_type ipv4 ip_proto tcp dst_port 21 ct_state -trk skip_sw in_hw in_hw_count 1 <---- action order 1: ct zone 0 helper ipv4-tcp-ftp pipe index 2 ref 1 bind 1 used_hw_stats delayed This might cause the flower filter not to work as expected in the HW.

A race condition exists where a synchronous (noqueue) transfer can be active during a system suspend. This can cause a null pointer dereference exception to occur when the system resumes. Example order of events leading to the exception: 1. spi_sync() calls __spi_transfer_message_noqueue() which sets ctlr->cur_msg 2. Spi transfer begins via spi_transfer_one_message() 3. System is suspended interrupting the transfer context 4. System is resumed 6. spi_controller_resume() calls spi_start_queue() which resets cur_msg to NULL 7. Spi transfer context resumes and spi_finalize_current_message() is called which dereferences cur_msg (which is now NULL) Wait for synchronous transfers to complete before suspending by acquiring the bus mutex and setting/checking a suspend flag.

BPF_END and BPF_NEG has a different specification for the source bit in the opcode compared to other ALU/ALU64 instructions, and is either reserved or use to specify the byte swap endianness. In both cases the source bit does not encode source operand location, and src_reg is a reserved field. backtrack_insn() currently does not differentiate BPF_END and BPF_NEG from other ALU/ALU64 instructions, which leads to r0 being incorrectly marked as precise when processing BPF_ALU | BPF_TO_BE | BPF_END instructions. This commit teaches backtrack_insn() to correctly mark precision for such case. While precise tracking of BPF_NEG and other BPF_END instructions are correct and does not need fixing, this commit opt to process all BPF_NEG and BPF_END instructions within the same if-clause to better align with current convention used in the verifier (e.g. check_alu_op).

The "hs_gear" variable is used to program the PHY settings (submode) during ufs_qcom_power_up_sequence(). Currently, it is being updated every time the agreed gear changes. Due to this, if the gear got downscaled before suspend (runtime/system), then while resuming, the PHY settings for the lower gear will be applied first and later when scaling to max gear with REINIT, the PHY settings for the max gear will be applied. This adds a latency while resuming and also really not needed as the PHY gear settings are backwards compatible i.e., we can continue using the PHY settings for max gear with lower gear speed. So let's update the "hs_gear" variable _only_ when the agreed gear is greater than the current one. This guarantees that the PHY settings will be changed only during probe time and fatal error condition. Due to this, UFSHCD_QUIRK_REINIT_AFTER_MAX_GEAR_SWITCH can now be skipped when the PM operation is in progress.

Often this would cause strange crashes as the mutexes would be freed while they were being used. Looking at the code, there is a lifetime problem as the controlling thread that spawns the work allocates the "struct stress" structures that are passed to the workqueue threads. Then when the workqueue threads are finished, they free the stress struct that was passed to them. Unfortunately the workqueue work_struct node is in the stress struct. Which means the work_struct is freed before the work thread returns and while flush_workqueue is waiting. It seems like a better idea to have the controlling thread both allocate and free the stress structures, so that we can be sure we don't corrupt the workqueue by freeing the structure prematurely. So this patch reworks the test to do so, and with this change I no longer see the early flush_workqueue returns.

Such mismatch is an indicator that something really went wrong and only printing a warning message (and stack trace) is not enough to prevent a corruption. Allowing a transaction to commit with such an extent buffer will trigger an error if we ever try to read it from disk due to a generation mismatch with its parent generation. So abort the current transaction with -EUCLEAN if we notice a generation mismatch. For this we need to pass a transaction handle to btrfs_mark_buffer_dirty() which is always available except in test code, in which case we can pass NULL since it operates on dummy extent buffers and all test roots have a single node/leaf (root node at level 0).

As David Kaplan describes in his debugging of the issue, it is caused by a couple of KCSAN-generated constructors which aren't processed by objtool: "When KCSAN is enabled, GCC generates lots of constructor functions named _sub_I_00099_0 which call __tsan_init and then return. The returns in these are generally annotated normally by objtool and fixed up at runtime. But objtool runs on vmlinux.o and vmlinux.o does not include a couple of object files that are in vmlinux, like init/version-timestamp.o and .vmlinux.export.o, both of which contain _sub_I_00099_0 functions. As a result, the returns in these functions are not annotated, and the panic occurs when we call one of them in do_ctors and it uses the default return thunk. This difference can be seen by counting the number of these functions in the object files: $ objdump -d vmlinux.o|grep -c "<_sub_I_00099_0>:" 2601 $ objdump -d vmlinux|grep -c "<_sub_I_00099_0>:" 2603 If these functions are only run during kernel boot, there is no speculation concern." Fix it by disabling KCSAN on version-timestamp.o and .vmlinux.export.o so the extra functions don't get generated. KASAN and GCOV are already disabled for those files.

The maximum result of this subtraction is defined by the RCU_FANOUT_LEAF Kconfig option, which on 64-bit systems defaults to 16 (resulting in a maximum shift of 15), but which can be set up as high as 64 (resulting in a maximum shift of 63). A value of 31 can result in sign extension, resulting in 0xffffffff80000000 instead of the desired 0x80000000. A value of 32 or greater triggers undefined behavior per the C standard. This bug has not been known to cause issues because almost all kernels take the default CONFIG_RCU_FANOUT_LEAF=16. Furthermore, as long as a given compiler gives a deterministic non-zero result for 1<<N for N>=32, the code correctly invokes all SRCU callbacks, albeit wasting CPU time along the way. This commit therefore substitutes the correct 1UL for the buggy 1. Found by Linux Verification Center (linuxtesting.org) with SVACE.

However, after this [1] commit, UBSAN is triggered under many new scenarios that weren't detected before, such as in struct definitions with fixed-size trailing arrays used as flexible arrays. As a result, CONFIG_UBSAN_TRAP=y has become a very aggressive option to enable except for specific situations. `make kselftest-merge` applies CONFIG_UBSAN_TRAP=y to the kernel config for all selftests, which makes many of them fail because of system hangs during boot. This change removes the config option from the lkdtm kselftest and configures the ARRAY_BOUNDS test to look for UBSAN reports rather than relying on the calling process being killed.

The driver initially triggers a reset-to-zero of the two timers but this reset is only performed on the next rising clock. For the first timer this is ok - it will be in the next 60ns (16MHz clock). For the chained second timer this will only happen after the first timer overflows, i.e. after 2^16 clocks (~4ms with a 16MHz clock). So with other words the scheduler clock resets to 0 after the first 2^16 clock cycles. It looks like that the scheduler does not like this and behaves wrongly over its lifetime, e.g. some tasks are scheduled with a long delay. Why that is and if there are additional requirements for this behaviour has not been further analysed. There is a simple fix for resetting the second timer as well when the first timer is reset and this is to set the ATMEL_TC_ASWTRG_SET bit in the Channel Mode register (CMR) of the first timer. This will also rise the TIOA line (clock input of the second timer) when a software trigger respective SYNC is issued.

Moreover accelerations performed beyond enqueue time are error prone because rcu_seq_snap() then may return the snapshot for a new grace period that is not going to be started. Remove these dangerous and needless accelerations and introduce instead assertions reporting leaking unaccelerated callbacks beyond enqueue time.

When it gets stuck temporarily, it usually gets released in a few seconds, and sometimes up to one or two minutes. If the CSD lock stays stuck for more than several minutes, it never seems to get unstuck, and gradually more and more things in the system end up also getting stuck. In the latter case, we should just give up, so the system can dump out a little more information about what went wrong, and, with panic_on_oops and a kdump kernel loaded, dump a whole bunch more information about what might have gone wrong. In addition, there is an smp.panic_on_ipistall kernel boot parameter that by default retains the old behavior, but when set enables the panic after the CSD lock has been stuck for more than the specified number of milliseconds, as in 300,000 for five minutes.

As a result the workqueue related locking scenario for a function A may be spuriously accounted as an inversion against the locking scenario of function B such as in the following model: long A(void *arg) { mutex_lock(&mutex); mutex_unlock(&mutex); } long B(void *arg) { } void launchA(void) { work_on_cpu(0, A, NULL); } void launchB(void) { mutex_lock(&mutex); work_on_cpu(1, B, NULL); mutex_unlock(&mutex); } launchA and launchB running concurrently have no chance to deadlock. However the above can be reported by lockdep as a possible locking inversion because the works containing A() and B() are treated as belonging to the same locking class. The following shows an existing example of such a spurious lockdep splat: ====================================================== WARNING: possible circular locking dependency detected 6.6.0-rc1-00065-g934ebd6e5359 #35409 Not tainted ------------------------------------------------------ kworker/0:1/9 is trying to acquire lock: ffffffff9bc72f30 (cpu_hotplug_lock){++++}-{0:0}, at: _cpu_down+0x57/0x2b0 but task is already holding lock: ffff9e3bc0057e60 ((work_completion)(&wfc.work)){+.+.}-{0:0}, at: process_scheduled_works+0x216/0x500 which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #2 ((work_completion)(&wfc.work)){+.+.}-{0:0}: __flush_work+0x83/0x4e0 work_on_cpu+0x97/0xc0 rcu_nocb_cpu_offload+0x62/0xb0 rcu_nocb_toggle+0xd0/0x1d0 kthread+0xe6/0x120 ret_from_fork+0x2f/0x40 ret_from_fork_asm+0x1b/0x30 -> #1 (rcu_state.barrier_mutex){+.+.}-{3:3}: __mutex_lock+0x81/0xc80 rcu_nocb_cpu_deoffload+0x38/0xb0 rcu_nocb_toggle+0x144/0x1d0 kthread+0xe6/0x120 ret_from_fork+0x2f/0x40 ret_from_fork_asm+0x1b/0x30 -> #0 (cpu_hotplug_lock){++++}-{0:0}: __lock_acquire+0x1538/0x2500 lock_acquire+0xbf/0x2a0 percpu_down_write+0x31/0x200 _cpu_down+0x57/0x2b0 __cpu_down_maps_locked+0x10/0x20 work_for_cpu_fn+0x15/0x20 process_scheduled_works+0x2a7/0x500 worker_thread+0x173/0x330 kthread+0xe6/0x120 ret_from_fork+0x2f/0x40 ret_from_fork_asm+0x1b/0x30 other info that might help us debug this: Chain exists of: cpu_hotplug_lock --> rcu_state.barrier_mutex --> (work_completion)(&wfc.work) Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock((work_completion)(&wfc.work)); lock(rcu_state.barrier_mutex); lock((work_completion)(&wfc.work)); lock(cpu_hotplug_lock); *** DEADLOCK *** 2 locks held by kworker/0:1/9: #0: ffff900481068b38 ((wq_completion)events){+.+.}-{0:0}, at: process_scheduled_works+0x212/0x500 #1: ffff9e3bc0057e60 ((work_completion)(&wfc.work)){+.+.}-{0:0}, at: process_scheduled_works+0x216/0x500 stack backtrace: CPU: 0 PID: 9 Comm: kworker/0:1 Not tainted 6.6.0-rc1-00065-g934ebd6e5359 #35409 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.12.0-59-gc9ba5276e321-prebuilt.qemu.org 04/01/2014 Workqueue: events work_for_cpu_fn Call Trace: rcu-torture: rcu_torture_read_exit: Start of episode <TASK> dump_stack_lvl+0x4a/0x80 check_noncircular+0x132/0x150 __lock_acquire+0x1538/0x2500 lock_acquire+0xbf/0x2a0 ? _cpu_down+0x57/0x2b0 percpu_down_write+0x31/0x200 ? _cpu_down+0x57/0x2b0 _cpu_down+0x57/0x2b0 __cpu_down_maps_locked+0x10/0x20 work_for_cpu_fn+0x15/0x20 process_scheduled_works+0x2a7/0x500 worker_thread+0x173/0x330 ? __pfx_worker_thread+0x10/0x10 kthread+0xe6/0x120 ? __pfx_kthread+0x10/0x10 ret_from_fork+0x2f/0x40 ? __pfx_kthread+0x10/0x10 ret_from_fork_asm+0x1b/0x30 </TASK Fix this with providing one lock class key per work_on_cpu() caller.

The commit: 9391a3f9c7f1 ("[PATCH] x86_64: Clear more state when ignoring empty node in SRAT parsing") ... that introduced minimal size of a NUMA node does not explain why a node size cannot be less than 4MB and what boot failures this restriction might fix. Fixes have been submitted to the core MM code to tighten up the memory topologies it accepts and to not crash on weird input: mm: page_alloc: skip memoryless nodes entirely mm: memory_hotplug: drop memoryless node from fallback lists Andrew has accepted them into the -mm tree, but there are no stable SHA1's yet. This patch drops the limitation for minimal node size on x86: - which works around the crash without the fixes to the core MM. - makes x86 topologies less weird, - removes an arbitrary and undocumented limitation on NUMA topologies.

In the above scenario, a fragmented packet is received for self peer, for which rx_tid and rx_frags are not initialized in datapath. While handling this fragment, crash is observed as the rx_frag list is uninitialized and when we walk in ath12k_dp_rx_h_sort_frags, skb null leads to exception. To address this, before processing received fragments we check dp_setup_done flag is set to ensure that peer has completed its dp peer setup for fragment queue, else ignore processing the fragments.
