[PATCH openEuler-5.10 1/6] slub: add back check for free nonslab objects
by Zheng Zengkai 28 May '22
by Zheng Zengkai 28 May '22
28 May '22
From: Kefeng Wang <wangkefeng.wang(a)huawei.com>
mainline inclusion
from mainline-v5.16-rc1
commit d0fe47c64152a63ceed4b9f29ac56371407fa7b4
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I57LS2
CVE: NA
backport: openEuler-22.03-LTS
--------------------------------
After commit f227f0faf63b ("slub: fix unreclaimable slab stat for bulk
free"), the check for free nonslab page is replaced by VM_BUG_ON_PAGE,
which only check with CONFIG_DEBUG_VM enabled, but this config may
impact performance, so it only for debug.
Commit 0937502af7c9 ("slub: Add check for kfree() of non slab objects.")
add the ability, which should be needed in any configs to catch the
invalid free, they even could be potential issue, eg, memory corruption,
use after free and double free, so replace VM_BUG_ON_PAGE to
WARN_ON_ONCE, add object address printing to help use to debug the
issue.

[PATCH openEuler-5.10 v2 1/4] ipv6: per-netns exclusive flowlabel checks
by Zheng Zengkai 28 May '22
by Zheng Zengkai 28 May '22
28 May '22
From: Willem de Bruijn <willemb(a)google.com>
stable inclusion
from stable-v5.10.102
commit 4f523f15e5d753ac055302bc29ca9677d6692eed
bugzilla: https://gitee.com/openeuler/kernel/issues/I575QT
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit 0b0dff5b3b98c5c7ce848151df9da0b3cdf0cc8b upstream.
Ipv6 flowlabels historically require a reservation before use.
Optionally in exclusive mode (e.g., user-private).
Commit 59c820b2317f ("ipv6: elide flowlabel check if no exclusive
leases exist") introduced a fastpath that avoids this check when no
exclusive leases exist in the system, and thus any flowlabel use
will be granted.
That allows skipping the control operation to reserve a flowlabel
entirely. Though with a warning if the fast path fails:
This is an optimization. Robust applications still have to revert to
requesting leases if the fast path fails due to an exclusive lease.
Still, this is subtle. Better isolate network namespaces from each
other. Flowlabels are per-netns. Also record per-netns whether
exclusive leases are in use. Then behavior does not change based on
activity in other netns.
Changes
v2
- wrap in IS_ENABLED(CONFIG_IPV6) to avoid breakage if disabled
Fixes: 59c820b2317f ("ipv6: elide flowlabel check if no exclusive leases exist")

commit 4f523f15e5d753ac055302bc29ca9677d6692eed
bugzilla: https://gitee.com/openeuler/kernel/issues/I575QT
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit 0b0dff5b3b98c5c7ce848151df9da0b3cdf0cc8b upstream.
Ipv6 flowlabels historically require a reservation before use.
Optionally in exclusive mode (e.g., user-private).
Commit 59c820b2317f ("ipv6: elide flowlabel check if no exclusive
leases exist") introduced a fastpath that avoids this check when no
exclusive leases exist in the system, and thus any flowlabel use
will be granted.
That allows skipping the control operation to reserve a flowlabel
entirely. Though with a warning if the fast path fails:
This is an optimization. Robust applications still have to revert to
requesting leases if the fast path fails due to an exclusive lease.
Still, this is subtle. Better isolate network namespaces from each
other. Flowlabels are per-netns. Also record per-netns whether
exclusive leases are in use. Then behavior does not change based on
activity in other netns.
Changes
v2
- wrap in IS_ENABLED(CONFIG_IPV6) to avoid breakage if disabled

[PATCH openEuler-5.10 01/26] readahead: introduce FMODE_CTL_WILLNEED to read first 2MB of file
by Zheng Zengkai 23 May '22

category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I53R0H
CVE: NA
backport: openEuler-22.03-LTS
-------------------------------------------------
In some scenario, likely spark-sql, almost all meta file's size is
less then 2MB and applications read these smaller files in random
mode. That means, it may issue multiple times random io to rotate
disk, which can cause performance degradation.
To improve the small files random read, we try to read the first
2MB into pagecache on the first time of read. Then it can avoid
multiple random io.
In fact, applications can call fadvise system with POSIX_FADV_WILLNEED
to achieve this goal. But, some apps may cannot easily do that.
So, we provide a new file flag FMODE_CTL_WILLNEED.

mainline inclusion
from mainline-v5.13-rc1
commit 37f0e514db660f03f8982b8f4fbbd4b2740abe7d
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I545NW
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
Currently we purge the ingress_skb queue only when psock
refcnt goes down to 0, so locking the queue is not necessary,
but in order to be called during ->close, we have to lock it
here.

[PATCH openEuler-5.10 1/2] net/x25: Fix null-ptr-deref caused by x25_disconnect

commit 5c94b6205e87411dbe9dc1ca088eb36b8837fb47
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I5661B
CVE: CVE-2022-1516
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
[ Upstream commit 7781607938c8371d4c2b243527430241c62e39c2 ]
When the link layer is terminating, x25->neighbour will be set to NULL
in x25_disconnect(). As a result, it could cause null-ptr-deref bugs in
x25_sendmsg(),x25_recvmsg() and x25_connect(). One of the bugs is
shown below.
(Thread 1) | (Thread 2)
x25_link_terminated() | x25_recvmsg()
x25_kill_by_neigh() | ...
x25_disconnect() | lock_sock(sk)
... | ...
x25->neighbour = NULL //(1) |
... | x25->neighbour->extended //(2)
The code sets NULL to x25->neighbour in position (1) and dereferences
x25->neighbour in position (2), which could cause null-ptr-deref bug.
This patch adds lock_sock() in x25_kill_by_neigh() in order to synchronize
with x25_sendmsg(), x25_recvmsg() and x25_connect(). What`s more, the
sock held by lock_sock() is not NULL, because it is extracted from x25_list
and uses x25_list_lock to synchronize.
Fixes: 4becb7ee5b3d ("net/x25: Fix x25_neigh refcnt leak when x25 disconnect")

[PATCH openEuler-5.10 01/43] rcu: Prevent expedited GP from enabling tick on offline CPU
by Zheng Zengkai 10 May '22
by Zheng Zengkai 10 May '22
10 May '22
From: "Paul E. McKenney" <paulmck(a)kernel.org>
mainline inclusion
from mainline-v5.17-rc1
commit 147f04b14adde831eb4a0a1e378667429732f9e8
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I53ILL
CVE: NA
-------------------------------------------------------------------------
If an RCU expedited grace period starts just when a CPU is in the process
of going offline, so that the outgoing CPU has completed its pass through
stop-machine but has not yet completed its final dive into the idle loop,
RCU will attempt to enable that CPU's scheduling-clock tick via a call
to tick_dep_set_cpu(). For this to happen, that CPU has to have been
online when the expedited grace period completed its CPU-selection phase.
This is pointless: The outgoing CPU has interrupts disabled, so it cannot
take a scheduling-clock tick anyway. In addition, the tick_dep_set_cpu()
function's eventual call to irq_work_queue_on() will splat as follows:
smpboot: CPU 1 is now offline

This commit therefore avoids invoking tick_dep_set_cpu() on offlined
CPUs to limit both futility and false-positive splats.

[PATCH openEuler-5.10 1/5] arm64: kdump: Update the name of crashk_low_res
by Zheng Zengkai 28 Apr '22

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I545H8
CVE: NA
-------------------------------------------------------------------------
To be consistent with the style of other ARCHs such as x86, the kexec
commit b5a34a20984c ("arm64: support more than one crash kernel regions")
requires all crash regions to be named "Crash kernel". Update the name of
crashk_low_res, so that we can directly use the latest kexec tool without
having to maintain a private version.

[PATCH openEuler-5.10 01/13] ixgbe: add the ability for the PF to disable VF link state

commit 366fd1000995d4cf64e1a61a0d78a051550b9841
category: bugfix
bugzilla: 186597, https://gitee.com/src-openeuler/kernel/issues/I532H9
CVE: CVE-2021-33061
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
Add support for ndo_set_vf_link_state the Network Device Option that
allows the PF driver to control the virtual link state of the VF devices.
Without this change a VF cannot be disabled/enabled by the administrator.
In the implementation the auto state takes over PF link state to
VF link setting, the enable state is not supported, the disable state
shut off the VF link regardless of the PF setting.

[PATCH openEuler-5.10 01/42] can: usb_8dev: usb_8dev_start_xmit(): fix double dev_kfree_skb() in error path
by Zheng Zengkai 27 Apr '22
by Zheng Zengkai 27 Apr '22
27 Apr '22
From: Hangyu Hua <hbh25y(a)gmail.com>
stable inclusion
from stable-v5.10.110
commit 5318cdf4fd834856ce71238b064f35386f9ef528
category: bugfix
bugzilla: 186592 https://gitee.com/src-openeuler/kernel/issues/I51YBQ?from=project-issue
CVE: CVE-2022-28388
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit 3d3925ff6433f98992685a9679613a2cc97f3ce2 upstream.
There is no need to call dev_kfree_skb() when usb_submit_urb() fails
because can_put_echo_skb() deletes original skb and
can_free_echo_skb() deletes the cloned skb.
Fixes: 0024d8ad1639 ("can: usb_8dev: Add support for USB2CAN interface from 8 devices")

[PATCH openEuler-1.0-LTS] x86/tsc: Make cur->adjusted values in package#1 to be the same

CVE: NA
----------------------------------------------------------------
When resume from S4 on Zhaoxin 2 packages platform that support
X86_FEATURE_TSC_ADJUST,
the following warning messages appear:
[ 327.445302] [Firmware Bug]: TSC ADJUST differs: CPU15 45960750 -->

78394770. Restoring
[ 329.209169] [Firmware Bug]: TSC ADJUST differs: CPU9 45960750 -->
78394770. Restoring
The reason is:
Step 1: Bring up.
TSC is sync after bring up with following settings:
MSR 0x3b cur->adjusted
Package#0 CPU 0-7 0 0
Package#1 first CPU value1 value1
Package#1 non-first CPU value1 value1
Step 2: Suspend to S4.
Settings in Step 1 are not changed in this Step.
Step 3: Bring up caused by S4 wake up event.
TSC is sync when bring up with following settings:
MSR 0x3b cur->adjusted
Package#0 CPU 0-7 0 0
Package#1 first CPU value2 value2
Package#1 non-first CPU value2 value2
Step 4: Resume from S4.
When resuming from S4, Current TSC synchronous mechanism
cause following settings:
MSR 0x3b cur->adjusted
Package#0 CPU 0-7 0 0
Package#1 first CPU value2 value2
Package#1 non-first CPU value2 value1
In these Steps, value1 != 0 and value2 != value1.
In Step4, as function tsc_store_and_check_tsc_adjust() do, when the value
of MSR 0x3b on the non-first online CPU in package#1 is equal to the value
of cur->adjusted on the first online CPU in the same package,
the cur->adjusted value on this non-first online CPU will hold the old
value1.
This cause function tsc_verify_tsc_adjust() set the value of MSR 0x3b on the
non-first online CPUs in the package#1 to the old value1 and print the
beginning warning messages.
Fix it by setting cur->adjusted value on the non-first online CPU in a
package
to the value of MSR 0x3b on the same CPU when they are not equal.

[PATCH openEuler-1.0-LTS] Add support for PxSCT.LPM set based on actual LPM circumstances

CVE: NA
----------------------------------------------------------------
AHCI Spec shows that the PxSCTL.IPM field in each port must be programmed
to disallow device initiated LPM requests when HBA can not support
transitions to the LPM state. The current LPM driver has no restrictions
on LPM transitions when enabling device initiated LPM.

In AHCI spec, PhyRdy Change Interrupt cannot coexist with
Link Power Management (LPM). While LPM driver would disable
PhyRdy Change interrupt without checking whether HBA supports
LPM or not before enabling it. Therefore, if enabling LPM from
LPM driver by default, we can not disable it from BIOS without
influence Hotplug out capability.

[PATCH openEuler-1.0-LTS] XHCI:Fix some device identify fail when enable xHCI runtime suspend
by LeoLiuoc 26 Apr '22
by LeoLiuoc 26 Apr '22

zhaoxin inclusion

bugzilla: https://gitee.com/openeuler/kernel/issues/I54V16
CVE: NA
----------------------------------------------------------------
If plug out device form xhci with runtime suspend enabled.
On the one hand, driver will disconnect this device and send disabled
slot command to xhci.
On the other hand, without no device connect to xhci, PM core will
call xhci suspend function to let xhci go to D3 to save power.
However there is a temporal competition to get xhci lock between
disable slot command interrupt and xhci suspend.
If xhci suspend function get xhci lock first, then this function will
clear xhci command ring. It will get error command trb when driver to
handle disable slot command interrupt. This is a serious error for
driver and driver will cleanup xhci. So，any device connect to this
xhci port again will not be recognized.
In order to fix this issues, we let disable slot command interrupt ISR
to get xhci lock first. So, add a delay in xhci suspend function before
to get xhci lock.

[PATCH openEuler-1.0-LTS] EHCI: Clear wakeup signal locked in S0, state when device plug in

CVE: NA
----------------------------------------------------------------
If we plug in a LS/FS device on USB2 port of EHCI, it will latch a wakeup
signal in EHCI internal. This is a bug of EHCI for Some project of
ZhaoXin. If enable EHCI runtime suspend and no device attach.
PM core will let EHCI go to D3 to save power. However, once EHCI go to D3,
it will release wakeup signal that latched on device connect to port
during S0. Which will generate a SCI interrupt and bring EHCI to D0.
But without device connect, EHCI will go to D3 again.
So, there is suspend-resume loop and generate SCI interrupt Continuously.
In order to fix this issues, we need to clear the wakeup signal latched
in EHCI when EHCI suspend function is called.

When the RTC divider is changed from reset to an operating time base,
the first update cycle should be 500ms later. But on some Zhaoxin SOCs,
this first update cycle is one second later.
So set RTC time on these Zhaoxin SOCs will causing 500ms delay.
Skip setup RTC divider on these SOCs in mc146818_set_time to fix it.

[ Upstream commit 9a564bccb78a76740ea9d75a259942df8143d02c ]
Add __GFP_ZERO flag for compose_sadb_supported in function pfkey_register
to initialize the buffer of supp_skb to fix a kernel-info-leak issue.
1) Function pfkey_register calls compose_sadb_supported to request
a sk_buff. 2) compose_sadb_supported calls alloc_sbk to allocate
a sk_buff, but it doesn't zero it. 3) If auth_len is greater 0, then
compose_sadb_supported treats the memory as a struct sadb_supported and
begins to initialize. But it just initializes the field sadb_supported_len
and field sadb_supported_exttype without field sadb_supported_reserved.

[PATCH openEuler-1.0-LTS 01/15] binder: use euid from cred instead of using task
by Laibin Qiu 15 Apr '22
by Laibin Qiu 15 Apr '22
15 Apr '22
From: Todd Kjos <tkjos(a)google.com>
stable inclusion
from linux-4.19.218
commit 5d40061285b81a7e213dc9b37acc4a0545eedf32
--------------------------------
commit 29bc22ac5e5bc63275e850f0c8fc549e3d0e306b upstream.
Save the 'struct cred' associated with a binder process
at initial open to avoid potential race conditions
when converting to an euid.
Set a transaction's sender_euid from the 'struct cred'
saved at binder_open() instead of looking up the euid
from the binder proc's 'struct task'. This ensures
the euid is associated with the security context that
of the task that opened binder.

mainline inclusion
from mainline-v5.17-rc6
commit ddbd89deb7d32b1fbb879f48d68fda1a8ac58e8e
category: bugfix
bugzilla: 186478, https://gitee.com/src-openeuler/kernel/issues/I503W4
CVE: CVE-2022-0854
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
The problem I'm addressing was discovered by the LTP test covering
cve-2018-1000204.
A short description of what happens follows:
1) The test case issues a command code 00 (TEST UNIT READY) via the SG_IO
interface with: dxfer_len == 524288, dxdfer_dir == SG_DXFER_FROM_DEV
and a corresponding dxferp. The peculiar thing about this is that TUR
is not reading from the device.
2) In sg_start_req() the invocation of blk_rq_map_user() effectively
bounces the user-space buffer. As if the device was to transfer into
it. Since commit a45b599ad808 ("scsi: sg: allocate with __GFP_ZERO in
sg_build_indirect()") we make sure this first bounce buffer is
allocated with GFP_ZERO.
3) For the rest of the story we keep ignoring that we have a TUR, so the
device won't touch the buffer we prepare as if the we had a
DMA_FROM_DEVICE type of situation. My setup uses a virtio-scsi device
and the buffer allocated by SG is mapped by the function
virtqueue_add_split() which uses DMA_FROM_DEVICE for the "in" sgs (here
scatter-gather and not scsi generics). This mapping involves bouncing
via the swiotlb (we need swiotlb to do virtio in protected guest like
s390 Secure Execution, or AMD SEV).
4) When the SCSI TUR is done, we first copy back the content of the second
(that is swiotlb) bounce buffer (which most likely contains some
previous IO data), to the first bounce buffer, which contains all
zeros. Then we copy back the content of the first bounce buffer to
the user-space buffer.
5) The test case detects that the buffer, which it zero-initialized,
ain't all zeros and fails.
One can argue that this is an swiotlb problem, because without swiotlb
we leak all zeros, and the swiotlb should be transparent in a sense that
it does not affect the outcome (if all other participants are well
behaved).
Copying the content of the original buffer into the swiotlb buffer is
the only way I can think of to make swiotlb transparent in such
scenarios. So let's do just that if in doubt, but allow the driver
to tell us that the whole mapped buffer is going to be overwritten,
in which case we can preserve the old behavior and avoid the performance
impact of the extra bounce.

[PATCH openEuler-1.0-LTS 01/62] PM: wakeup: simplify the output logic of pm_show_wakelocks()

commit cf94a8a3ff3d7aa06742f1beb5166fa45ba72122
--------------------------------
commit c9d967b2ce40d71e968eb839f36c936b8a9cf1ea upstream.
The buffer handling in pm_show_wakelocks() is tricky, and hopefully
correct. Ensure it really is correct by using sysfs_emit_at() which
handles all of the tricky string handling logic in a PAGE_SIZE buffer
for us automatically as this is a sysfs file being read from.

[PATCH openEuler-1.0-LTS 1/3] printk: Convert a use of sprintf to snprintf in console_unlock

commit 5661dd95a2958634485bb1a53f90a6ab621d4b0c
category: bugfix
bugzilla: 91291
CVE: N/A
--------------------------------
When CONFIG_PRINTK is disabled (e.g. when building allnoconfig), clang
warns:
../kernel/printk/printk.c:2416:10: warning: 'sprintf' will always
overflow; destination buffer has size 0, but format string expands to at
least 33 [-Wfortify-source]
len = sprintf(text,
^
1 warning generated.
It is not wrong; text has a zero size when CONFIG_PRINTK is disabled
because LOG_LINE_MAX and PREFIX_MAX are both zero. Change to snprintf so
that this case is explicitly handled without any risk of overflow.

Some distributions are about to switch to Python 3 support only.
This means that /usr/bin/python, which is Python 2, is not available
anymore. Hence, switch scripts to use Python 3 explicitly.
*** ERROR: ambiguous python shebang in ***/power/pm-graph/sleepgraph.py:

[PATCH openEuler-1.0-LTS] serial: 8250: Fix max baud limit in generic 8250 port
by Laibin Qiu 02 Apr '22
by Laibin Qiu 02 Apr '22
02 Apr '22
From: Serge Semin <Sergey.Semin(a)baikalelectronics.ru>

from linux-4.19.130
commit 0eeaf62981ecc79e8395ca8caa1570eaf3a12257
category: bugfix
bugzilla: 89545
CVE: N/A
------------------------------------------------
[ Upstream commit 7b668c064ec33f3d687c3a413d05e355172e6c92 ]
Standard 8250 UART ports are designed in a way so they can communicate
with baud rates up to 1/16 of a reference frequency. It's expected from
most of the currently supported UART controllers. That's why the former
version of serial8250_get_baud_rate() method called uart_get_baud_rate()
with min and max baud rates passed as (port->uartclk / 16 / UART_DIV_MAX)
and ((port->uartclk + tolerance) / 16) respectively. Doing otherwise, like
it was suggested in commit ("serial: 8250_mtk: support big baud rate."),
caused acceptance of bauds, which was higher than the normal UART
controllers actually supported. As a result if some user-space program
requested to set a baud greater than (uartclk / 16) it would have been
permitted without truncation, but then serial8250_get_divisor(baud)
(which calls uart_get_divisor() to get the reference clock divisor) would
have returned a zero divisor. Setting zero divisor will cause an
unpredictable effect varying from chip to chip. In case of DW APB UART the
communications just stop.
Lets fix this problem by getting back the limitation of (uartclk +
tolerance) / 16 maximum baud supported by the generic 8250 port. Mediatek
8250 UART ports driver developer shouldn't have touched it in the first
place notably seeing he already provided a custom version of set_termios()
callback in that glue-driver which took into account the extended baud
rate values and accordingly updated the standard and vendor-specific
divisor latch registers anyway.
Fixes: 81bb549fdf14 ("serial: 8250_mtk: support big baud rate.")

Ramaxel inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4ZR0O
CVE: NA
------------------------------------
There are some issues of the driver that cannot be fixed now.
The driver is not good enough for the LTS quality requirements of
openEuler，so remove it.

[PATCH OLK-5.10 0/2] apply to delete some files of spfc and spnic drivers in architecture
by Yanling Song 26 Mar '22
by Yanling Song 26 Mar '22
26 Mar '22
There are some issues of drivers that cannot be fixed now. The drivers are not good enought for the LTS quality requirements of openEuler，so apply to remove.
Yanling Song (1):
net/spnic: Remove spnic driver.
Yun Xu (1):
SCSI: spfc: remove SPFC driver

category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I49RB2
CVE: NA
---------------------------------------------------
Fix modpost Section mismatch error in __mpam_device_create() and others.
These warnings will occur in high version gcc, for example 10.1.0.
[...]
WARNING: vmlinux.o(.text+0x2ed88): Section mismatch in reference from the
function __mpam_device_create() to the function .init.text:mpam_device_alloc()
The function __mpam_device_create() references
the function __init mpam_device_alloc().
This is often because __mpam_device_create lacks a __init
annotation or the annotation of mpam_device_alloc is wrong.
WARNING: vmlinux.o(.text.unlikely+0xa5c): Section mismatch in reference from
the function mpam_resctrl_init() to the function .init.text:mpam_init_padding()
The function mpam_resctrl_init() references
the function __init mpam_init_padding().
This is often because mpam_resctrl_init lacks a __init
annotation or the annotation of mpam_init_padding is wrong.
WARNING: vmlinux.o(.text.unlikely+0x5a9c): Section mismatch in reference from
the function resctrl_group_init() to the function .init.text:resctrl_group_setup_root()
The function resctrl_group_init() references
the function __init resctrl_group_setup_root().
This is often because resctrl_group_init lacks a __init
annotation or the annotation of resctrl_group_setup_root is wrong.

commit 0c4bcfdecb1ac0967619ee7ff44871d93c08c909
category: bugfix
bugzilla: 186448, https://gitee.com/openeuler/kernel/issues/I4YS7O
CVE: CVE-2022-1011
--------------------------------
In FOPEN_DIRECT_IO mode, fuse_file_write_iter() calls
fuse_direct_write_iter(), which normally calls fuse_direct_io(), which then
imports the write buffer with fuse_get_user_pages(), which uses
iov_iter_get_pages() to grab references to userspace pages instead of
actually copying memory.
On the filesystem device side, these pages can then either be read to
userspace (via fuse_dev_read()), or splice()d over into a pipe using
fuse_dev_splice_read() as pipe buffers with &nosteal_pipe_buf_ops.
This is wrong because after fuse_dev_do_read() unlocks the FUSE request,
the userspace filesystem can mark the request as completed, causing write()
to return. At that point, the userspace filesystem should no longer have
access to the pipe buffer.
Fix by copying pages coming from the user address space to new pipe
buffers.

[PATCH openEuler-1.0-LTS 1/3] veth: Do not record rx queue hint in veth_xmit
by Laibin Qiu 17 Mar '22
by Laibin Qiu 17 Mar '22

From: Daniel Borkmann <daniel(a)iogearbox.net>
stable inclusion
from linux-4.19.226
commit bd6e97e2b6f59a19894c7032a83f03ad38ede28e
--------------------------------
commit 710ad98c363a66a0cd8526465426c5c5f8377ee0 upstream.
Laurent reported that they have seen a significant amount of TCP retransmissions
at high throughput from applications residing in network namespaces talking to
the outside world via veths. The drops were seen on the qdisc layer (fq_codel,
as per systemd default) of the phys device such as ena or virtio_net due to all
traffic hitting a _single_ TX queue _despite_ multi-queue device. (Note that the
setup was _not_ using XDP on veths as the issue is generic.)
More specifically, after edbea9220251 ("veth: Store queue_mapping independently
of XDP prog presence") which made it all the way back to v4.19.184+,
skb_record_rx_queue() would set skb->queue_mapping to 1 (given 1 RX and 1 TX
queue by default for veths) instead of leaving at 0.
This is eventually retained and callbacks like ena_select_queue() will also pick
single queue via netdev_core_pick_tx()'s ndo_select_queue() once all the traffic
is forwarded to that device via upper stack or other means. Similarly, for others
not implementing ndo_select_queue() if XPS is disabled, netdev_pick_tx() might
call into the skb_tx_hash() and check for prior skb_rx_queue_recorded() as well.
In general, it is a _bad_ idea for virtual devices like veth to mess around with
queue selection [by default]. Given dev->real_num_tx_queues is by default 1,
the skb->queue_mapping was left untouched, and so prior to edbea9220251 the
netdev_core_pick_tx() could do its job upon __dev_queue_xmit() on the phys device.
Unbreak this and restore prior behavior by removing the skb_record_rx_queue()
from veth_xmit() altogether.
If the veth peer has an XDP program attached, then it would return the first RX
queue index in xdp_md->rx_queue_index (unless configured in non-default manner).
However, this is still better than breaking the generic case.
Fixes: edbea9220251 ("veth: Store queue_mapping independently of XDP prog presence")
Fixes: 638264dc9022 ("veth: Support per queue XDP ring")

在kernel.spec中对内核模块进行压缩，压缩为.xz格式，可以减少内核模块约72%的磁盘消耗。
对于openEuler操作系统，可以减少约175 MB磁盘消耗。
目前openEuler中modprobe等工具都支持.xz格式的内核模块，该更改对正常使用无影响。
此功能在centos、opensuse均已默认打开。
压缩命令：
find $RPM_BUILD_ROOT/lib/modules/ -type f -name '*.ko' | xargs -n1 -P`nproc --all` xz

[PATCH openEuler-1.0-LTS] crypto: pcrypt - Fix user-after-free on module unload
by Laibin Qiu 15 Mar '22
by Laibin Qiu 15 Mar '22

From: Herbert Xu <herbert(a)gondor.apana.org.au>
stable inclusion
from linux-4.19.102
commit 47ef5cb878817127bd3d54c3578bbbd3f7c2bf2c
CVE: NA
-------------------------------
[ Upstream commit 07bfd9bdf568a38d9440c607b72342036011f727 ]
On module unload of pcrypt we must unregister the crypto algorithms
first and then tear down the padata structure. As otherwise the
crypto algorithms are still alive and can be used while the padata
structure is being freed.
Fixes: 5068c7a883d1 ("crypto: pcrypt - Add pcrypt crypto...")

[PATCH openEuler-1.0-LTS 1/2] mm: fix unable to use reliable memory in page cache

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4SK3S
CVE: NA
----------------------------------------------
It is inaccurate when accumulate percpu variable without lock,
it will result in pagecache_reliable_pages to be negative in
sometime, and will prevent pagecache using reliable memory.
For more accurate statistic, replace percpu variable by percpu_counter.
The additional percpu_counter will be access in alloc_pages, the init
of these two percpu_conter is too late in late_initcall, allocations
that use alloc_pages should have to check if the two counter has been
inited, that will introduce latency, in order to sovle this, init the
two percpu_counter in advance.

-------------------------------------------------
It appears that there are some buffer overflows in EVT_TRANSACTION.
This happens because the length parameters that are passed to memcpy
come directly from skb->data and are not guarded in any way.

[PATCH openEuler-5.10 1/3] net/hinic: Fix null pointer dereference in hinic_physical_port_id

category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I4XF98
CVE: NA
-----------------------------------------------------------------------
The hinic driver currently generates a NULL pointer dereference
when performing the hinicadm tool command during device probe.
This is because the hinicadm process accesses the NULL hwif
pointer in the hwdev which have not been allocated in probe.
Fix this by checking the initialization state of device before
accessing it.

-------------------------------------------------
This reverts commit b445547ec1bbd3e7bf4b1c142550942f70527d95.
Since both mq-deadline and BFQ completely ignore hctx they are passed to
their dispatch function and dispatch whatever request they deem fit
checking whether any request for a particular hctx is queued is just
pointless since we'll very likely get a request from a different hctx
anyway. In the following commit we'll deal with lock contention in these
IO schedulers in presence of multiple HW queues in a different way.

bugzilla: https://gitee.com/openeuler/kernel/issues/I4WOPM
CVE: NA
--------------------------------
cfs_bandwidth_usage_inc() need hold jump_label_mutex and
might sleep, so we can not call it in atomic context.
Fix this by moving cfs_bandwidth_usage_{inc,dec}() out of
rcu read critical section.

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
When overlayfs is running on top of xfs and the user unlinks a file in
the overlay, overlayfs will create a whiteout inode and ask xfs to
"rename" the whiteout file atop the one being unlinked. If the file
being unlinked loses its one nlink, we then have to put the inode on the
unlinked list.
This requires us to grab the AGI buffer of the whiteout inode to take it
off the unlinked list (which is where whiteouts are created) and to grab
the AGI buffer of the file being deleted. If the whiteout was created
in a higher numbered AG than the file being deleted, we'll lock the AGIs
in the wrong order and deadlock.
Therefore, grab all the AGI locks we think we'll need ahead of time, and
in order of increasing AG number per the locking rules.

[PATCH openEuler-1.0-LTS 1/3] block: add a switch for precise iostat accounting
by Yang Yingliang 09 Mar '22

From: Zhang Wensheng <zhangwensheng5(a)huawei.com>
hulk inclusion
category: bugfix
bugzilla: 39265, https://gitee.com/openeuler/kernel/issues/I4WC06
CVE: NA
-----------------------------------------------
When the inflight IOs are slow and no new IOs are issued, we expect
iostat could manifest the IO hang problem. However after
commit 9c6dea45e6f7 ("block: delete part_round_stats and switch to less
precise counting"), io_tick and time_in_queue will not be updated until
the end of IO, and the avgqu-sz and %util columns of iostat will be zero.
To fix it, we could fallback to the implementation before commit
9c6dea45e6f7, but it may cause performance regression on NVMe device
or bio-based device (due to overhead of inflight calculation),
so add a switch to control whether or not to use precise iostat
accounting. It can be enabled by adding "precise_iostat=1" in kernel
boot cmdline. When precise accouting is enabled, io_tick and time_in_queue
will be updated when accessing /proc/diskstats and
/sys/block/sdX/sdXN/stat.

[PATCH openEuler-5.10] Revert "efi/libstub: arm64: Relax 2M alignment again for relocatable kernels"

--------------------------------
This reverts commit c6d2a109d90440e9e5e927a740128a35acf9d0b5.
I got the following messages when booting kernel:
EFI stub: Booting Linux Kernel...
EFI stub: EFI_RNG_PROTOCOL unavailable, KASLR will be disabled
EFI stub: Using DTB from configuration table
EFI stub: Exiting boot services and installing virtual address map...
...
[ 0.000000] CPU features: kernel page table isolation forced ON by KASLR
[ 0.000000] CPU features: detected: Kernel page table isolation (KPTI)
[ 3.393380] KASLR disabled due to lack of seed
KPTI is forced on by KASLR, but in fact KASLR is not enabled, it's
because kaslr_offset() returns non-zero in kaslr_requires_kpti().
To avoid this problem, when efi kaslr is disabled, make image
MIN_KIMG_ALIGN align which is used to get KASLR offset in
primary_entry(), so kaslr_offset() will returns 0.

In bfq_dispatch_requestfunction, it may have function call:
bfq_dispatch_request
__bfq_dispatch_request
bfq_select_queue
bfq_bfqq_expire
__bfq_bfqd_reset_in_service
bfq_put_queue
kmem_cache_free
In this function call, in_serv_queue has beed expired and meet the
conditions to free. In the function bfq_dispatch_request, the address
of in_serv_queue pointing to has been released. For getting the value
of idle_timer_disabled, it will get flags value from the address which
in_serv_queue pointing to, then the problem of use-after-free happens;
Fix the problem by check in_serv_queue == bfqd->in_service_queue, to
get the value of idle_timer_disabled if in_serve_queue is equel to
bfqd->in_service_queue. If the space of in_serv_queue pointing has
been released, this judge will aviod use-after-free problem.
And if in_serv_queue may be expired or finished, the idle_timer_disabled
will be false which would not give effects to bfq_update_dispatch_stats.

category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4SA9G
---------------------------
Automatically set the GENHD_FL_EXT_DEVT flag for all disks allocated
without an explicit number of minors. This is what all new block
drivers should do, so make sure it is the default without boilerplate
code.

[PATCH openEuler-1.0-LTS] hugetlbfs: fix a truncation issue in hugepages parameter

commit e79ce9832316e09529b212a21278d68240ccbf1f
category: bugfix
bugzilla: 186043
CVE: NA
-------------------------------------------------
When we specify a large number for node in hugepages parameter, it may
be parsed to another number due to truncation in this statement:
node = tmp;
For example, add following parameter in command line:
hugepagesz=1G hugepages=4294967297:5
and kernel will allocate 5 hugepages for node 1 instead of ignoring it.
I move the validation check earlier to fix this issue, and slightly
simplifies the condition here.

各位好，
根据前期沟通，OSV、驱动兼容性SIG都对内核接口兼容性提出了诉求。根据前期
沟通的信息，以 openEuler-20.03-LTS 驱动列表、兼容性KABI 白名单为基础，
以如下几个方面为白名单移除或新增的输入，形成一份 openEuler-22.03-LTS
兼容性 KABI 白名单初稿，请大家评审。

KABI (Kernel Application Binary Interface) 兼容，即内核与驱动的二进制兼容。
就是驱动不用重新编译，就可以在新内核上安装使用。如果驱动用到的接口都
是兼容的，那么驱动就可以不用重新编译就可以在新版本安装使用。上游社区
考虑到便于开发、和防止架构腐化，不考虑 KABI 的兼容性。业界的 KABI 兼容
都是由 Linux 发行版来做的，而且兼容的接口越多、维护时间越长，维护成本
也越高。
openEuler 通过多次与下游OSV和驱动团队交流，根据下游反馈的诉求，
openEuler-22.03-LTS 版本，提供一定范围的 KABI 兼容能力，目的是
使常用的板卡驱动，在 openEuler-22.03-LTS 版本能兼容。
KABI 兼容列表白名单的主要输入是驱动（ko），我们根据下游的反馈，在
openEuler-20.03-LTS 驱动列表的基础上，新增nvidia.ko、nvidia_vgpu_vfio.ko，
作为兼容的目标，得到驱动列表如下。
ARM64 版本拟兼容的驱动（ko）列表：
amdgpu.ko
bnx2.ko
bnx2x.ko
bnxt_en.ko
bnxt_re.ko
hclge.ko
hclgevf.ko
hifc.ko
hinic.ko
hnae3.ko
hns3.ko
i40e.ko
ice.ko
igb.ko
ixgbe.ko
ixgbevf.ko
lpfc.ko
megaraid_sas.ko
mlx4_core.ko
mlx4_ib.ko
mlx5_core.ko
mlx5_ib.ko
mpt3sas.ko
nvidia.ko
nvidia_vgpu_vfio.ko
nouveau.ko
nvme.ko
qed.ko
qede.ko
qla2xxx.ko
smartpqi.ko
tg3.ko
txgbe.ko
X86 版本拟兼容的驱动（ko）列表：
amdgpu.ko
bnx2.ko
bnx2x.ko
bnxt_en.ko
bnxt_re.ko
hifc.ko
hinic.ko
i40e.ko
ice.ko
igb.ko
ixgbe.ko
ixgbevf.ko
lpfc.ko
megaraid_sas.ko
mlx4_core.ko
mlx4_ib.ko
mlx5_core.ko
mlx5_ib.ko
mpt3sas.ko
nvidia.ko
nvidia_vgpu_vfio.ko
nouveau.ko
nvme.ko
qed.ko
qede.ko
qla2xxx.ko
smartpqi.ko
tg3.ko
txgbe.ko
重要的说明和提示：
1. 上述列表中多数驱动，还没有针对 openEuler-22.03-LTS 的正式二进制版本，因此我们
根据开源的版本或相近的版本收集了相关 KABI 列表，可能与板卡厂商的最终发布
的版本存在少量差异。下游OSV或驱动团队如果发现有接口没在给出的列表中的，
可以在评审过程中提出来。
2. 如果有新增 KABI 兼容性的诉求，需要给出需要兼容的 KABI 接口名称，以及使用
到的驱动名称，以方便评估。
3. 评审反馈，可以在 issue 中反馈，https://gitee.com/openeuler/kernel/issues/I4U6NZ
也可以通过回复邮件反馈。
4. 收集评审反馈信息的时间为1周，截止到下周五（3月11日）下午17:00.

[PATCH openEuler-5.10 1/4] rseq, ptrace: Add PTRACE_GET_RSEQ_CONFIGURATION request
by Zheng Zengkai 03 Mar '22

03 Mar '22
From: Piotr Figiel <figiel(a)google.com>
mainline inclusion
from mainline-5.13-rc1
commit 90f093fa8ea48e5d991332cee160b761423d55c1
category: feature
feature: Userspace percpu
bugzilla: https://gitee.com/openeuler/kernel/issues/I4W2BQ
CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
For userspace checkpoint and restore (C/R) a way of getting process state
containing RSEQ configuration is needed.
There are two ways this information is going to be used:
- to re-enable RSEQ for threads which had it enabled before C/R
- to detect if a thread was in a critical section during C/R
Since C/R preserves TLS memory and addresses RSEQ ABI will be restored
using the address registered before C/R.
Detection whether the thread is in a critical section during C/R is needed
to enforce behavior of RSEQ abort during C/R. Attaching with ptrace()
before registers are dumped itself doesn't cause RSEQ abort.
Restoring the instruction pointer within the critical section is
problematic because rseq_cs may get cleared before the control is passed
to the migrated application code leading to RSEQ invariants not being
preserved. C/R code will use RSEQ ABI address to find the abort handler
to which the instruction pointer needs to be set.
To achieve above goals expose the RSEQ ABI address and the signature value
with the new ptrace request PTRACE_GET_RSEQ_CONFIGURATION.
This new ptrace request can also be used by debuggers so they are aware
of stops within restartable sequences in progress.

If this config is enabled, block mapping is not used. The linear address page
table is mapped to 4 KB. As a result, the TLB miss rate is high, affecting
performance.
For examples, tested by libMicro benchmark:

[PATCH openEuler-5.10 1/9] kfence: Add a module parameter to adjust kfence objects

CVE: NA
--------------------------------
KFENCE is designed to be enabled in production kernels, but it can
be also useful in some debug situations. For machines with limited
memory and CPU resources, KASAN is really hard to run. Fortunately,
KFENCE can be a suitable candidate. For KFENCE running on a single
machine, the possibility of discovering existed bugs will increase
as the increasing of KFENCE objects, but this will cost more memory.
In order to balance the possibility of discovering existed bugs and
memory cost, KFENCE objects need to be adjusted according to memory
resources for a compiled kernel Image. Add a module parameter to
adjust KFENCE objects will make kfence to use in different machines
with the same kernel Image.
In short, the following reasons motivate us to add this parameter.
1) In some debug situations, this will make kfence flexible.
2) For some production machines with different memory and CPU size,
this will reduce the kernel-Image-version burden.
The main change is just using kfence_num_objects to replace config
CONFIG_KFENCE_NUM_OBJECTS for dynamic configuration convenient. To
make compatible, kfence_metadata and alloc_covered are alloced by
memblock_alloc. Considering "cat /sys/kernel/debug/kfence/objects"
will read kfence_metadata, the initialization of this fs should
check whether kfence_metadata is successfully allocated.
Unfortunately, dynamic allocation require the KFENCE pool size to
be a configurable variable, which lead to additional instructions
(eg, load) added to the fast path of the memory allocation. As a
result, the performance will degrade. To avoid bad performance in
production machine, an ugly macro is used to isolate the changes.

- Overview
kernel NULL pointer dereference triggered in folio_mark_dirty() when mount and operate on a crafted f2fs image
- Reproduce

The root cause is for special file: e.g. character, block, fifo or socket file,
f2fs doesn't assign address space operations pointer array for mapping->a_ops field,
so, in a fuzzed image, SSA table indicates a data block belong to special file, when
f2fs tries to migrate that block, it causes NULL pointer access once move_data_page()
calls a_ops->set_dirty_page().

[PATCH openEuler-1.0-LTS 01/18] mm: Ratelimited mirrored memory related warning messages

CVE: NA
--------------------------------
If system has mirrored memory, memblock will try to allocate mirrored
memory firstly and fallback to non-mirrored memory when fails, but if with
limited mirrored memory or some numa node without mirrored memory, lots of
warning message about memblock allocation will occur.
This patch ratelimit the warning message to avoid a very long print during
bootup.

Hulk Robot reported a panic in put_page_testzero() when testing
madvise() with MADV_SOFT_OFFLINE. The BUG() is triggered when retrying
get_any_page(). This is because we keep MF_COUNT_INCREASED flag in
second try but the refcnt is not increased.
page dumped because: VM_BUG_ON_PAGE(page_ref_count(page) == 0)

各位好,
openEuler 22.03 LTS 已经发布了第二轮测试版本，为支撑版本发布和维护，
我们基于 OLK-5.10 创建了 openEuler-22.03-LTS 分支。
该分支用于 22.03-LTS 版本的维护，不再接受未事先规划的新特性。
仅接受 bugfix、CVE 和 性能优化。如有补丁需要合入该分支，需在补丁标题
增加版本分支前缀。
- 需要推送到该分支的补丁，需要首先合入 OLK-5.10；该分支原则上不接受
没有合入 OLK-5.10 的补丁。
- 22.03-LTS 发布之后，可以接受从 OLK-5.10 backport 的不影响兼容性的
优化、硬件使能等影响小的特性。
同时基于 OLK-5.10 创建 openEuler-22.09 分支，用于支撑 22.09 创新版本
的开发。创新版本接受新特性、Preview 特性、验证特性等，促进新技术、新
特性的成熟和稳定。
OLK-5.10 分支继续接受补丁合入请求。
新创建的分支路径：

bugzilla: 186269
CVE: CVE-2022-0617
-----------------------------------------------
udf_expand_file_adinicb() calls directly ->writepage to write data
expanded into a page. This however misses to setup inode for writeback
properly and so we can crash on inode->i_wb dereference when submitting
page for IO like:
BUG: kernel NULL pointer dereference, address: 0000000000000158
#PF: supervisor read access in kernel mode
...
<TASK>
__folio_start_writeback+0x2ac/0x350

udf_file_write_iter+0xbe/0x1b0 [udf]
new_sync_write+0x125/0x1c0
vfs_write+0x28e/0x400
Fix the problem by marking the page dirty and going through the standard
writeback path to write the page. Strictly speaking we would not even
have to write the page but we want to catch e.g. ENOSPC errors early.

[PATCH openEuler-5.10 04/25] ahci: Fix some bugs like plugin support and sata link stability when user enable ahci RTD3

CVE: NA
----------------------------------------------------------------
The kernel driver now will disable interrupt when port is suspended,
causing plugin not work. It is useful to make plugin work，when the
plugin interrupt is enabled with power management status.
Adding pm_request_resume() is to reume port for plugin or PME signal
waking up controller which in D3.
with the AHCI controller frequently enters into D3 and leaves from D3,
the identify cmd may be timeout when controller resumes and establishes
a connect with the device.it is effective to delay 10ms between
controller resume and port resume，with link’s smooth transition.
with non power management request and power management competing with
each other in queue, it is often found that block IO hang 120s when
system disk is suspending or resuming.it is now guaranteed that PM
requests will enter the queue no matter other non-PM requests are
waiting. Increase the pm_only counter before checking whether any
non-PM blk_queue_enter() calls are in progress.
Meanwhile, the new blk_pm_request_resume() call is necessary to occur
during request assigned to a queue when device is suspended.

When the RTC divider is changed from reset to an operating time base,
the first update cycle should be 500ms later. But on some Zhaoxin SOCs,
this first update cycle is one second later.
So set RTC time on these Zhaoxin SOCs will causing 500ms delay.
Skip setup RTC divider on these SOCs in mc146818_set_time to fix it.

[PATCH openEuler-5.10 01/90] ACPICA: Interpreter: fix memory leak by using existing buffer
by Zheng Zengkai 23 Feb '22

bugzilla: https://gitee.com/openeuler/kernel/issues/I4T7OX
CVE: NA
--------------------------------
ACPICA commit 52d1da5dcbd79a722b70f02a1a83f04088f51ff6
There was a memory leak that ocurred when a _CID object is defined as
a package containing string objects. When _CID is checked for any
possible repairs, it calls a helper function to repair _HID (because
_CID basically contains multiple _HID entries).
The _HID repair function assumes that string objects are standalone
objects that are not contained inside of any packages. The _HID
repair function replaces the string object with a brand new object
and attempts to delete the old object by decrementing the reference
count of the old object. Strings inside of packages have a reference
count of 2 so the _HID repair function leaves this object in a
dangling state and causes a memory leak.
Instead of allocating a brand new object and removing the old object,
use the existing object when repairing the _HID object.

这里依据上次兆芯同事解释的代码逻辑：
X86架构情况下，兆芯的相应平台不执行CMOS_WRITE(save_freq_select,
RTC_FREQ_SELECT), 即 commit message中Skip setup RTC divider on these SOCs
in mc146818_set_time to fix it;
而其他架构(#else 分支)，仍然需要执行CMOS_WRITE(save_freq_select,
RTC_FREQ_SELECT);
@Jackie @ Leo，
两位看下理解是否OK？

CVE: NA
--------------------------------
During kernel copy_from_user processing, the kernel triggers a RAS
exception when reading pages. In this solution, we identify this
scenario in the kernel do_sea processing process, send SIGBUS signals
to the process that triggers copy_from_user and isolate memory pages,
preventing kernel panic.
At the same time, we use both cmdline(uce_kernel_recovery) and proc
(/proc/sys/kernel/uce_kernel_recovery) to control this feature on/off.

[PATCH openEuler-1.0-LTS] bpf: Verifer, adjust_scalar_min_max_vals to always call update_reg_bounds()
by Yang Yingliang 22 Feb '22
by Yang Yingliang 22 Feb '22
22 Feb '22
From: John Fastabend <john.fastabend(a)gmail.com>
mainline inclusion
from mainline-v5.7-rc1
commit 294f2fc6da27620a506e6c050241655459ccd6bd
category: bugfix
bugzilla: NA
CVE: CVE-2021-4159
-----------------------------------------------
Currently, for all op verification we call __red_deduce_bounds() and
__red_bound_offset() but we only call __update_reg_bounds() in bitwise
ops. However, we could benefit from calling __update_reg_bounds() in
BPF_ADD, BPF_SUB, and BPF_MUL cases as well.
For example, a register with state 'R1_w=invP0' when we subtract from
it,
w1 -= 2
Before coerce we will now have an smin_value=S64_MIN, smax_value=U64_MAX
and unsigned bounds umin_value=0, umax_value=U64_MAX. These will then
be clamped to S32_MIN, U32_MAX values by coerce in the case of alu32 op
as done in above example. However tnum will be a constant because the
ALU op is done on a constant.
Without update_reg_bounds() we have a scenario where tnum is a const
but our unsigned bounds do not reflect this. By calling update_reg_bounds
after coerce to 32bit we further refine the umin_value to U64_MAX in the
alu64 case or U32_MAX in the alu32 case above.

[PATCH openEuler-1.0-LTS] livepatch/x86: Fix incorrect use of 'strncpy'
by Yang Yingliang 22 Feb '22
by Yang Yingliang 22 Feb '22
22 Feb '22
From: Zheng Yejian <zhengyejian1(a)huawei.com>
hulk inclusion
category: bugfix
bugzilla: 186253, https://gitee.com/openeuler/kernel/issues/I4TYA9
CVE: NA
-----------------------------------------------
Refer to following codes, 'strncpy' would stop copying if Null character
encountered. For example, when 'code' is "53 be 00 0a 05", 'old_code'
would be "53 be 00 00 00".
> 276 static unsigned char *klp_old_code(unsigned char *code)
> 277 {
> 278 static union klp_code_union old_code;
> 279
> 280 strncpy(old_code.code, code, JMP_E9_INSN_SIZE);
> 281 return old_code.code;
> 282 }
As a result, the instructions cannot be restored completely, and the
system becomes abnormal.

CVE: NA
--------------------------------
The system would hang up when the Phytium S2500 communicates with
some BMCs after several rounds of transactions, unless we reset
the controller timeout counter manually by calling firmware through
SMC.
The reset in intf_mem_inw was missed previously.

CVE: NA
--------------------------------
If dm_get_device() create dd in multipath_message(),
and then call table_deps() after dm_put_table_device(),
it will lead to concurrency UAF bugs.
One of the concurrency UAF can be shown as below:
(USE) | (FREE)
| target_message
| multipath_message
| dm_put_device
| dm_put_table_device #
| kfree(td) # table_device *td
ioctl # DM_TABLE_DEPS_CMD | ...
table_deps | ...
dm_get_live_or_inactive_table | ...
retrieve_dep | ...
list_for_each_entry | ...
deps->dev[count++] = | ...
huge_encode_dev | ...
(dd->dm_dev->bdev->bd_dev) | list_del(&dd->list)
| kfree(dd) # dm_dev_internal
The root cause of UAF bugs is that find_device() failed in
dm_get_device() and will create dd and refcount set 1, kfree()
in dm_put_table() is not protected. When td, which there are
still pointers point to, is released, the concurrency UAF bug
will happen.
This patch add a flag to determine whether to create a new dd.

你这个不断的来源是哪里的，如果是上游社区的，不断作者应该是原作者。
并标明补丁的上游 commit。
如果还没进入上游版本，也需要给出上游讨论的链接。

看这个补丁签名，社区应该是要讨论的。
你如果要推送到 openEuler 社区，需要有你自己的签名。
表明你对这个补丁负责。

[PATCH openEuler-5.10 1/9] livepatch: Fix kobject refcount bug on klp_init_patch_early failure path
by Zheng Zengkai 17 Feb '22
by Zheng Zengkai 17 Feb '22
17 Feb '22
From: David Vernet <void(a)manifault.com>
mainline inclusion
from mainline-v5.17-rc1
commit 5ef3dd20555e8e878ac390a71e658db5fd02845c
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4TF7T
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
When enabling a klp patch with klp_enable_patch(), klp_init_patch_early()
is invoked to initialize the kobjects for the patch itself, as well as the
'struct klp_object' and 'struct klp_func' objects that comprise it.
However, there are some error paths in klp_enable_patch() where some
kobjects may have been initialized with kobject_init(), but an error code
is still returned due to e.g. a 'struct klp_object' having a NULL funcs
pointer.
In these paths, the initial reference of the kobject of the 'struct
klp_patch' may never be released, along with one or more of its objects and
their functions, as kobject_put() is not invoked on the cleanup path if
klp_init_patch_early() returns an error code.
For example, if an object entry such as the following were added to the
sample livepatch module's klp patch, it would cause the vmlinux klp_object,
and its klp_func which updates 'cmdline_proc_show', to never be released:
static struct klp_object objs[] = {
{
/* name being NULL means vmlinux */
.funcs = funcs,
},
{
/* NULL funcs -- would cause reference leak */
.name = "kvm",
}, { }
};
Without this change, if CONFIG_DEBUG_KOBJECT is enabled, and the sample klp
patch is loaded, the kobjects (the patch, the vmlinux 'struct klp_object',
and its func) are observed as initialized, but never released, in the dmesg
log output. With the change, these kobject references no longer fail to be
released as the error case is properly handled before they are initialized.
Since 81fd525cedd9 ("[Huawei] livepatch: Add klp_{register,unregister}_patch
for stop_machine model"), klp_register_patch was born out of klp_enable_patch
with similar issue, we also fix it in this patch.

If the server then returns a regular file, we will happily return a
file descriptor with uninitialised open state.
The fix is to return the expected ENOTDIR error in these cases.

[PATCH openEuler-1.0-LTS] configfs: fix a race in configfs_{,un}register_subsystem()
by Yang Yingliang 15 Feb '22

hulk inclusion
category: bugfix
bugzilla: 186233, https://gitee.com/src-openeuler/kernel/issues/I4TLA2?from=project-issue
CVE: NA
-----------------------------------------------
When configfs_register_subsystem() or configfs_unregister_subsystem()
is executing link_group() or unlink_group(),
it is possible that two processes add or delete list concurrently.
Some unfortunate interleavings of them can cause kernel panic.
One of cases is:
A --> B --> C --> D
A <-- B <-- C <-- D
delete list_head *B | delete list_head *C
--------------------------------|-----------------------------------
configfs_unregister_subsystem | configfs_unregister_subsystem
unlink_group | unlink_group
unlink_obj | unlink_obj
list_del_init | list_del_init
__list_del_entry | __list_del_entry
__list_del | __list_del
// next == C |
next->prev = prev |
| next->prev = prev
prev->next = next |
| // prev == B
| prev->next = next
Fix this by adding mutex when calling link_group() or unlink_group(),
but parent configfs_subsystem is NULL when config_item is root.
So I create a mutex configfs_subsystem_mutex.

[PATCH openEuler-1.0-LTS] fs/filesystems.c: downgrade user-reachable WARN_ONCE() to pr_warn_once()
by Yang Yingliang 14 Feb '22
by Yang Yingliang 14 Feb '22
14 Feb '22
From: Eric Biggers <ebiggers(a)google.com>
mainline inclusion
from mainline-5.7-rc1
commit 26c5d78c976ca298e59a56f6101a97b618ba3539
category: bugfix
bugzilla: 34247
CVE: NA
---------------------------
After request_module(), nothing is stopping the module from being
unloaded until someone takes a reference to it via try_get_module().
The WARN_ONCE() in get_fs_type() is thus user-reachable, via userspace
running 'rmmod' concurrently.
Since WARN_ONCE() is for kernel bugs only, not for user-reachable
situations, downgrade this warning to pr_warn_once().
Keep it printed once only, since the intent of this warning is to detect
a bug in modprobe at boot time. Printing the warning more than once
wouldn't really provide any useful extra information.
Fixes: 41124db869b7 ("fs: warn in case userspace lied about modprobe return")

commit 6cf253925df72e522c06dac09ede7e81a6e38121
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4T0ML
CVE: NA
-------------------------------------------------
Patch series "Fix NUMA nodes fallback list ordering".
For a NUMA system that has multiple nodes at same distance from other
nodes, the fallback list generation prefers same node order for them
instead of round-robin thereby penalizing one node over others. This
series fixes it.
More description of the problem and the fix is present in the patch
description.
This patch (of 2):
Print information message about the allocation fallback order for each
NUMA node during boot.
No functional changes here. This makes it easier to illustrate the
problem in the node fallback list generation, which the next patch
fixes.

[PATCH openEuler-1.0-LTS] drm/i915: Flush TLBs before releasing backing store
by Yang Yingliang 11 Feb '22
by Yang Yingliang 11 Feb '22
11 Feb '22
From: Tvrtko Ursulin <tvrtko.ursulin(a)intel.com>
stable inclusion
from linux-4.19.227
commit b188780649081782e341e52223db47c49f172712
CVE: CVE-2022-0330
--------------------------------
commit 7938d61591d33394a21bdd7797a245b65428f44c upstream.
We need to flush TLBs before releasing backing store otherwise userspace
is able to encounter stale entries if a) it is not declaring access to
certain buffers and b) it races with the backing store release from a
such undeclared execution already executing on the GPU in parallel.
The approach taken is to mark any buffer objects which were ever bound
to the GPU and to trigger a serialized TLB flush when their backing
store is released.
Alternatively the flushing could be done on VMA unbind, at which point
we would be able to ascertain whether there is potential a parallel GPU
execution (which could race), but essentially it boils down to paying
the cost of TLB flushes potentially needlessly at VMA unbind time (when
the backing store is not known to be going away so not needed for
safety), versus potentially needlessly at backing store relase time
(since we at that point cannot tell whether there is anything executing
on the GPU which uses that object).
Thereforce simplicity of implementation has been chosen for now with
scope to benchmark and refine later as required.
