[PATCH openEuler-1.0-LTS 1/4] rds: rds_rm_zerocopy_callback() use list_first_entry()
by Yongqiang Liu 06 Mar '23
by Yongqiang Liu 06 Mar '23
06 Mar '23
From: Pietro Borrello <borrello(a)diag.uniroma1.it>
stable inclusion
from stable-v4.19.273
commit 909d5eef5ce792bb76d7b5a9b7a6852b813d8cac
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I6I7UF
CVE: CVE-2023-1078
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
-------------------------------------------------
[ Upstream commit f753a68980cf4b59a80fe677619da2b1804f526d ]
rds_rm_zerocopy_callback() uses list_entry() on the head of a list
causing a type confusion.
Use list_first_entry() to actually access the first element of the
rs_zcookie_queue list.
Fixes: 9426bbc6de99 ("rds: use list structure to track information for zerocopy completion notification")

按照这个思路这里可以改成这样：
module_init
1. 首先判断所有容器中是否有hbm device， 构建链表
2. 如果链表不为空
那么执行模块的初始化，创建hbm_memory目录
如果链表为空
直接返回，释放链表
module_exit
释放链表中的资源，释放链表

----------------------------------------
This reverts commit 7f10ea522db56188ae46c5bbee7052a2b2797515.
This commit has a soft lock problem:
watchdog: BUG: soft lockup - CPU#22 stuck for 67s! [iscsid:16369]
Call Trace:
scsi_remove_target+0x548/0x7b0
? sdev_store_delete+0x90/0x90
? __mutex_lock_slowpath+0x10/0x10

iscsi_if_rx+0x2369/0x5060 [scsi_transport_iscsi]
The reason is that if other threads hold the reference count of the
kobject while waiting for the device to be released, it will keep
waiting in a loop.

CVE: NA
----------------------------------------
Bug report and analysis from Ding Hui.
During iSCSI session logout, if another task accesses the shost ipaddress
attr, we can get a KASAN UAF report like this:

We can easily reproduce by two tasks:
1. while :; do iscsiadm -m node --login; iscsiadm -m node --logout; done
2. while :; do cat \
/sys/devices/platform/host*/iscsi_host/host*/ipaddress; done

|- iscsi_host_free |
Fix the above bug by splitting the session removal into 2 parts:
1. removal from iSCSI class which includes sysfs and removal from host
tracking.
2. freeing of session.
During iscsi_tcp host and session removal we can remove the session from
sysfs then remove the host from sysfs. At this point we know userspace is
not accessing the kernel via sysfs so we can free the session and host.

--------------------------------
commit fda6c89fe3d9aca073495a664e1d5aea28cd4377 upstream.
lianhui reports that when MPLS fails to register the sysctl table
under new location (during device rename) the old pointers won't
get overwritten and may be freed again (double free).
Handle this gracefully. The best option would be unregistering
the MPLS from the device completely on failure, but unfortunately
mpls_ifdown() can fail. So failing fully is also unreliable.
Another option is to register the new table first then only
remove old one if the new one succeeds. That requires more
code, changes order of notifications and two tables may be
visible at the same time.
sysctl point is not used in the rest of the code - set to NULL
on failures and skip unregister if already NULL.

This reverts commit ab45921343c63dc9d461740e23003098697e0333.
We need to apply patch 788d0824269bef (io_uring: import 5.15-stable
io_uring) to move io_uring to separate directory and solve
the problem of CVE-2023-0240.
This patch fix a uaf problem of io_identity, and it can be reverted
since io_identity is removed in patch 788d0824269bef.

Kernel panic - not syncing: Fatal exception
Kernel Offset: 0x14400000 from 0xffffffff81000000 (relocation range: 0xffffffff80000000-0xffffffffbfffffff)
---[ end Kernel panic - not syncing: Fatal exception ]---
The problem was caused by selinux_file_open() accessing a file's fsec
being NULL, which indicated that the file_alloc_security hook should be
deleted later (at least after the file_open hook) when disabling SELinux
at runtime. Here I put it into the "allocating" part.

[PATCH openEuler-1.0-LTS 1/1] nbd: fix assignment error for first_minor in nbd_dev_add

category: bugfix
bugzilla: 188413, https://gitee.com/openeuler/kernel/issues/I6GWYG
CVE: NA
----------------------------------------
A panic error is like below:
nbd_genl_connect
nbd_dev_add
first_minor = index << part_shift; // index =-1
...
__device_add_disk
blk_alloc_devt
*devt = MKDEV(disk->major, disk->first_minor + part->partno);
// part->partno = 0， first_minor = 11...110000 major is covered
There, index < 0 will reassign an index, but here disk->first_minor is
assigned -1 << part_shift.
This causes to the creation of the device with the same major and minor
device numbers each time the incoming index<0, and this will lead to
creation of kobject failed:
Warning: kobject_add_internal failed for 4095:1048544 with -EEXIST, don't
try to register things with the same name in the same directory.
Fix it by moving the first_minor assignment down to after getting the new
index.

will be dissolved and released to buddy system, then isolate the hwpoison page.
For a hwpoison hugepage belong to dynamic hugetlb, we isolate the hugepage
without dissolve it. Add a check in free_huge_page_to_dhugetlb_pool() to
isolate the hwpoison hugepage directly. And keep HUGETLB_PAGE_DTOR after free
to ensure the PageHuge() check return true in dissolve_free_huge_page().
Fixes: 0f0535e57da("dhugetlb: skip dissolve hugepage belonging to dynamic hugetlb")

CVE: NA
----------------------------------------------
When a process is deleted from a group, the process does not apply for
memory from the shared group. Otherwise, the UAF problem occurs. We checked
this, but it didn't do a good job of preventing sp_alloc and del_task
concurrency. The process applies for memory after passing the check, which
violates our requirements and causes problems. The solution is to place the
checked code in the critical area to ensure that no memory can be allocated
after the check is passed.

[PATCH openEuler-1.0-LTS 1/5] mm/memcg_memfs_info: fix potential oom_lock recursion deadlock

bugzilla: https://gitee.com/openeuler/kernel/issues/I6AXGS
CVE: NA
--------------------------------
syzbot is reporting GFP_KERNEL allocation with oom_lock held when
reporting memcg OOM [1]. If this allocation triggers the global OOM
situation then the system can livelock because the GFP_KERNEL
allocation with oom_lock held cannot trigger the global OOM killer
because __alloc_pages_may_oom() fails to hold oom_lock.
The problem mentioned above has been fixed by patch[2]. The is the same
problem in memcg_memfs_info feature too. Refer to the patch[2], fix it by
removing the allocation from mem_cgroup_print_memfs_info() completely,
and pass static buffer when calling from memcg OOM path.

[ Upstream commit 112665286d08c87e66d699e7cba43c1497ad165f ]
Interrupts that occur in kernel mode expect that context tracking
is set to kernel. Enabling local irqs before context tracking
switches from guest to host means interrupts can come in and trigger
warnings about wrong context, and possibly worse.

[PATCH openEuler-1.0-LTS 1/2] net: bridge: mcast: add and enforce startup query interval minimum

bugzilla: https://gitee.com/openeuler/kernel/issues/I6DKZJ
CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
As reported[1] if startup query interval is set too low in combination with
large number of startup queries and we have multiple bridges or even a
single bridge with multiple querier vlans configured we can crash the
machine. Add a 1 second minimum which must be enforced by overwriting the
value if set lower (i.e. without returning an error) to avoid breaking
user-space. If that happens a log message is emitted to let the admin know
that the startup interval has been set to the minimum. It doesn't make
sense to make the startup interval lower than the normal query interval
so use the same value of 1 second. The issue has been present since these
intervals could be user-controlled.

CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
mount.cifs can pass a device with multiple delimiters in it. This will
cause rename(2) to fail with ENOENT.
V2:
- Make sanitize_path more readable.
- Fix multiple delimiters between UNC and prepath.
- Avoid a memory leak if a bad user starts putting a lot of delimiters
in the path on purpose.

sks in accept queue release by inet_child_forget()->inet_csk_destroy_sock(),
but psocks of child sks have not released.
To fix, add sock_map_destroy to release psocks.

[PATCH openEuler-5.10-LTS-SP1 01/87] NFSD: Fix verifier returned in stable WRITEs

commit d3d885507b52b28f54770a42d650251876d433a3
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0U6
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit f11ad7aa653130b71e2e89bed207f387718216d5 upstream.
RFC 8881 explains the purpose of the write verifier this way:
> The final portion of the result is the field writeverf. This field
> is the write verifier and is a cookie that the client can use to
> determine whether a server has changed instance state (e.g., server
> restart) between a call to WRITE and a subsequent call to either
> WRITE or COMMIT.
But then it says:
> This cookie MUST be unchanged during a single instance of the
> NFSv4.1 server and MUST be unique between instances of the NFSv4.1
> server. If the cookie changes, then the client MUST assume that
> any data written with an UNSTABLE4 value for committed and an old
> writeverf in the reply has been lost and will need to be
> recovered.
RFC 1813 has similar language for NFSv3. NFSv2 does not have a write
verifier since it doesn't implement the COMMIT procedure.
Since commit 19e0663ff9bc ("nfsd: Ensure sampling of the write
verifier is atomic with the write"), the Linux NFS server has
returned a boot-time-based verifier for UNSTABLE WRITEs, but a zero
verifier for FILE_SYNC and DATA_SYNC WRITEs. FILE_SYNC and DATA_SYNC
WRITEs are not followed up with a COMMIT, so there's no need for
clients to compare verifiers for stable writes.
However, by returning a different verifier for stable and unstable
writes, the above commit puts the Linux NFS server a step farther
out of compliance with the first MUST above. At least one NFS client
(FreeBSD) noticed the difference, making this a potential
regression.
[Removed down_write to fix the conflict in the cherry-pick. The
down_write functionality was no longer needed there. Upstream commit
555dbf1a9aac6d3150c8b52fa35f768a692f4eeb titled nfsd: Replace use of
rwsem with errseq_t removed those and replace it with new functionality
that was more scalable. This commit is already backported onto 5.10 and
so removing down_write ensures consistency with that change. Tested by
compiling and booting successfully. - kochera]

CVE: NA
--------------------------------
When nr_hugepages is configured, sharepool allocates hugepages first
from hugetlb pool, then from buddy system if the pool had been used up.
Current page release function treat the buddy system hugepages as
hugetlb pages, which caused HugePages_Rsvd to increase improperly.
Add a check in page release function:
if the page is temporary, do not call hugetlb_unreserve_pages.

bugzilla: https://gitee.com/openeuler/kernel/issues/I6BO2R
CVE: NA
--------------------------------
Now, There is some issues about LPI migration on ARM SMP platform.
For example, NIC device generates MSI and sends LPI to CPU0 via ITS,
meanwhile irqbalance running on CPU1 set irq affinty of NIC to CPU1,
the next interrupt will be sent to CPU2, due to the state of irq is
still in progress, kernel does not end up performing irq handler on
CPU2, which results in some userland service timeouts, the sequence
of events is shown as follows:
NIC CPU0 CPU1
Generate IRQ#1 READ_IAR
Lock irq_desc
Set IRQD_IN_PROGRESS
Unlock irq_desc
Lock irq_desc
Change LPI Affinity
Unlock irq_desc
Call irq_handler
Generate IRQ#2
READ_IAR
Lock irq_desc
Check IRQD_IN_PROGRESS
Unlock irq_desc
Return from interrupt#2
Lock irq_desc
Clear IRQD_IN_PROGRESS
Unlock irq_desc
return from interrupt#1
For this scenario, We can enable CONFIG_GENERIC_PENDING_IRQ to avoid this.
The CONFIG_GENERIC_PENDING_IRQ will delay all action that modify LPI
affinity until the next interrupt eoi handler.

[PATCH openEuler-1.0-LTS 1/3] jbd2: Fix data missing when reusing bh which is ready to be checkpointed

CVE: NA
Reference: https://lore.kernel.org/lkml/20230110015327.1181863-1-chengzhihao1@huawei.c…
--------------------------------
Following process will make data lost and could lead to a filesystem
corrupted problem:
1. jh(bh) is inserted into T1->t_checkpoint_list, bh is dirty, and
jh->b_transaction = NULL
2. T1 is added into journal->j_checkpoint_transactions.
3. Get bh prepare to write while doing checkpoing:
PA PB
do_get_write_access jbd2_log_do_checkpoint
spin_lock(&jh->b_state_lock)
if (buffer_dirty(bh))
clear_buffer_dirty(bh) // clear buffer dirty
set_buffer_jbddirty(bh)
transaction =
journal->j_checkpoint_transactions
jh = transaction->t_checkpoint_list
if (!buffer_dirty(bh))
__jbd2_journal_remove_checkpoint(jh)
// bh won't be flushed
jbd2_cleanup_journal_tail
__jbd2_journal_file_buffer(jh, transaction, BJ_Reserved)
4. Aborting journal/Power-cut before writing latest bh on journal area.
In this way we get a corrupted filesystem with bh's data lost.
Fix it by moving the clearing of buffer_dirty bit just before the call
to __jbd2_journal_file_buffer(), both bit clearing and jh->b_transaction
assignment are under journal->j_list_lock locked, so that
jbd2_log_do_checkpoint() will wait until jh's new transaction fininshed
even bh is currently not dirty. And journal_shrink_one_cp_list() won't
remove jh from checkpoint list if the buffer head is reused in
do_get_write_access().

CVE: NA
--------------------------------
When CONFIG_PARAVIRT is enabled, the code of {save,restore}_fl is
defined as:
ff 14 25 00 00 00 00 callq *0x0
which will be patched to call the xen paravirt function, or native
implementation, in 'paravirt_patch_64.c':
pushfq; popq %rax // for native_save_fl
pushq %rdi; popfq // for native_restore_fl
The orc metadata is generated with insn 'callq', so it can become
inconsistent with the real insn 'push;pop'.
This makes stacktrace on the 'pop' insn fail and incorrect stacktrace
result can be returned.
To prevent reliable stacktrace broken, check the insns when unwind
pt_regs stack frame:
When there are 'push;pop' combination and both insns don't change orc
entry, it means the stack state is inconsistent with orc on pop.
Add one slot to sp_offset for on original orc entry to get the correct
orc entry.

category: bugfix

CVE: CVE-2022-3707
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
If intel_gvt_dma_map_guest_page failed, it will call
ppgtt_invalidate_spt, which will finally free the spt.
But the caller function ppgtt_populate_spt_by_guest_entry
does not notice that, it will free spt again in its error
path.
Fix this by canceling the mapping of DMA address and freeing sub_spt.
Besides, leave the handle of spt destroy to caller function instead
of callee function when error occurs.

CVE: NA

--------------------------------
Ever since we added shadown format buffers to the log items, log
items need to handle the item being released with shadow buffers
attached. Due to the fact this requirement was added at the same
time we added new rmap/reflink intents, we missed the cleanup of
those items.
In theory, this means shadow buffers can be leaked in a very small
window when a shutdown is initiated. Testing with KASAN shows this
leak does not happen in practice - we haven't identified a single
leak in several years of shutdown testing since ~v4.8 kernels.
However, the intent whiteout cleanup mechanism results in every
cancelled intent in exactly the same state as this tiny race window
creates and so if intents down clean up shadow buffers on final
release we will leak the shadow buffer for just about every intent
we create.
Hence we start with this patch to close this condition off and
ensure that when whiteouts start to be used we don't leak lots of
memory.

stable inclusion
from stable-v4.19.270
commit f487d636e49bc1fdfbd8105bc1ab159164e2d8bd
category: bugfix
bugzilla: 188291, https://gitee.com/src-openeuler/kernel/issues/I6B1V2
CVE: CVE-2023-0394
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=…
--------------------------------
commit cb3e9864cdbe35ff6378966660edbcbac955fe17 upstream.
The total cork length created by ip6_append_data includes extension
headers, so we must exclude them when comparing them against the
IPV6_CHECKSUM offset which does not include extension headers.

[openEuler-5.10 1/4] SUNRPC: Clean up the handling of page padding in rpc_prepare_reply_pages()
by Zheng Zengkai 06 Feb '23
by Zheng Zengkai 06 Feb '23
06 Feb '23
From: Trond Myklebust <trond.myklebust(a)hammerspace.com>
mainline inclusion
from mainline-v5.11-rc1
commit 9ed5af268e88f6e5b65376be98d652b37cb20d7b
bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0MJ
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
rpc_prepare_reply_pages() currently expects the 'hdrsize' argument to
contain the length of the data that we expect to want placed in the head
kvec plus a count of 1 word of padding that is placed after the page data.
This is very confusing when trying to read the code, and sometimes leads
to callers adding an arbitrary value of '1' just in order to satisfy the
requirement (whether or not the page data actually needs such padding).
This patch aims to clarify the code by changing the 'hdrsize' argument
to remove that 1 word of padding. This means we need to subtract the
padding from all the existing callers.
Fixes: 02ef04e432ba ("NFS: Account for XDR pad of buf->pages")

driver inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I6BSMN
-----------------------------------------------------------------------
For ROH distributed scenario, EID is allocated by DHCP mode.
Driver needs to convert the origin MAC address to EID format,
and updates the destination MAC, chaddr and client id(if exists)
when transmit DHCP packets. Meantime, the chaddr field should
follow the source mac address, in order to make the dhcp
server reply to the right client. For the payload of
dhcp packet changed, so the checksum of L4 should be
calculated too.

commit d71a1c9fce184718d1b3a51a9e8a6e31cbbb45ce
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0ZE

-------------------------------------------------
commit 278d3ba61563ceed3cb248383ced19e14ec7bc1f upstream.
On 32bit-UP u64_stats_fetch_begin() disables only preemption. If the
reader is in preemptible context and the writer side
(u64_stats_update_begin*()) runs in an interrupt context (IRQ or
softirq) then the writer can update the stats during the read operation.
This update remains undetected.
Use u64_stats_fetch_begin_irq() to ensure the stats fetch on 32bit-UP
are not interrupted by a writer. 32bit-SMP remains unaffected by this
change.

[PATCH openEuler-1.0-LTS 1/3] mm: hwpoison: refactor refcount check handling
by Yongqiang Liu 04 Feb '23
by Yongqiang Liu 04 Feb '23
04 Feb '23
From: Yang Shi <shy828301(a)gmail.com>
stable inclusion
from stable-v5.15.86
commit a62b1bc603a1ded739e7cf543da29a3eb93cc534
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I6AR36
CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit dd0f230a0a80ff396c7ce587f16429f2a8131344 upstream.
Memory failure will report failure if the page still has extra pinned
refcount other than from hwpoison after the handler is done. Actually
the check is not necessary for all handlers, so move the check into
specific handlers. This would make the following keeping shmem page in
page cache patch easier.
There may be expected extra pin for some cases, for example, when the
page is dirty and in swapcache.

[PATCH openEuler-1.0-LTS 1/6] dhugetlb: backport dynamic hugetlb feature
by Yongqiang Liu 04 Feb '23
by Yongqiang Liu 04 Feb '23
04 Feb '23
From: Liu Shixin <liushixin2(a)hauwei.com>
hulk inclusion
category: feature
bugzilla: 46904, https://gitee.com/openeuler/kernel/issues/I6BDME
CVE: NA
--------------------------------
This feature has already beed supported on x86_64 and this is the origin
description:
Dynamic hugetlb which is based on Hugetlb, supports to be splited
dynamically in a specified cgroup. We add a hugetlb_pool in a
mem_cgroup to manage dynamic hugetlb for corresponding cgroup.
After dynamic hugepages are allocated for a cgroup, these hugepages
can be used as 1G/2M/4K pages by split/merge opreation.
It is now supported on arm64. This feature will be limited to depends on
ARM64_4K_PAGES and not support cont-bits hugepage. We merge the previous
patches into one patch which is patch[1]. While merge the code ,we found
some code can be isolated by config DYNAMIC_HUGETLB, so we add patch[2] to
re-isolated them. In patch[3], we restrict the feature on mentioned limit.
The patch[4] add skip of dissolve hugepage which may conflict with memory
hotplug and memory failure. The patch[5] set DYNAMIC_HUGETLB to y in
hulk_defconfig to enable by default.
This patch includes all previous patches and the patches list is recorded
in bugzilla.

From: Sebastian Andrzej Siewior <bigeasy(a)linutronix.de>
stable inclusion
from stable-v5.10.142
commit d71a1c9fce184718d1b3a51a9e8a6e31cbbb45ce
category: bugfix
bugzilla: 188217
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
-------------------------------------------------
commit 278d3ba61563ceed3cb248383ced19e14ec7bc1f upstream.
On 32bit-UP u64_stats_fetch_begin() disables only preemption. If the
reader is in preemptible context and the writer side
(u64_stats_update_begin*()) runs in an interrupt context (IRQ or
softirq) then the writer can update the stats during the read operation.
This update remains undetected.
Use u64_stats_fetch_begin_irq() to ensure the stats fetch on 32bit-UP
are not interrupted by a writer. 32bit-SMP remains unaffected by this
change.

From: Matthias May <matthias.may(a)westermo.com>
stable inclusion
from stable-v5.10.138
commit 38b83883ce4e4efe8ff0a727192219cac2668d42
category: bugfix
bugzilla: 188217
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
-------------------------------------------------
commit ca2bb69514a8bc7f83914122f0d596371352416c upstream.
According to Guillaume Nault RT_TOS should never be used for IPv6.
Quote:
RT_TOS() is an old macro used to interprete IPv4 TOS as described in
the obsolete RFC 1349. It's conceptually wrong to use it even in IPv4
code, although, given the current state of the code, most of the
existing calls have no consequence.
But using RT_TOS() in IPv6 code is always a bug: IPv6 never had a "TOS"
field to be interpreted the RFC 1349 way. There's no historical
compatibility to worry about.
Fixes: 3a56f86f1be6 ("geneve: handle ipv6 priority like ipv4 tos")

CONFIG_EFI_ZBOOT is introduced to openEuler 22.03 LTS SP1 by this
commit for loongarch and enabled by default:
e46780727555("efi/libstub: implement generic EFI zboot").
However, if is enabled, the compiled version cannot be booted on
openEuler 22.03 LTS. So, disable it on this version.

commit 4e3aa9238277597c6c7624f302d81a7b568b6f2d upstream.
Commit 2b1299322016 ("x86/speculation: Add RSB VM Exit protections")
made a right mess of the RSB stuffing, rewrite the whole thing to not
suck.
Thanks to Andrew for the enlightening comment about Post-Barrier RSB
things so we can make this code less magical.

[PATCH openEuler-5.10-LTS 01/11] rndis_wlan: Prevent buffer overflow in rndis_query_oid

category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I6AQJP
CVE: CVE-2023-23559
Reference: https://patchwork.kernel.org/project/linux-wireless/patch/20230111175031.70…
-------------------------------
Since resplen and respoffs are signed integers sufficiently
large values of unsigned int len and offset members of RNDIS
response will result in negative values of prior variables.
This may be utilized to bypass implemented security checks
to either extract memory contents by manipulating offset or
overflow the data buffer via memcpy by manipulating both
offset and len.
Additionally assure that sum of resplen and respoffs does not
overflow so buffer boundaries are kept.

category: bugfix

CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/…
-----------------------------------------
An argument list like "arg=val arg2 \"" can trigger a page fault if the
page pointed by 'args[0xffffffff]' is not mapped and potential memory
corruption otherwise (unlikely but possible if the bogus address is mapped
and contents happen to match the ascii value of the quote character).
The fix is to ensure that we load 'args[i-1]' only when (i > 0).
Prior to this commit the following command would trigger an
unhandled page fault in the kernel:

CVE: NA
-------------------------------------------------
The BMA software is a system management software offered by Huawei.
It supports the status monitoring, performance monitoring and
event monitoring of various components, including server CPUs,
memory hard disks, NICs, IB cards, PCIe cards,
RAID controller cards and optical modules.
In this version, the system resets due to the BMA spin lock
when the memory usage is too high, the vulnerability has been rectified.

--------------------------------
commit d1a997ba4c1bf65497d956aea90de42a6398f73a upstream.
When checking for libc rseq support in the library constructor, don't
only depend on the symbols presence, check that the registration was
completed.
This targets a scenario where the libc has rseq support but it is not
wired for the current architecture in 'bits/rseq.h', we want to fallback
to our internal registration mechanism.

[PATCH openEuler-5.10-LTS-SP1 01/14] tracing/osnoise: Properly unhook events if start_per_cpu_kthreads() fails

CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
If start_per_cpu_kthreads() called from osnoise_workload_start() returns
error, event hooks are left in broken state: unhook_irq_events() called
but unhook_thread_events() and unhook_softirq_events() not called, and
trace_osnoise_callback_enabled flag not cleared.
On the next tracer enable, hooks get not installed due to
trace_osnoise_callback_enabled flag.
And on the further tracer disable an attempt to remove non-installed
hooks happened, hitting a WARN_ON_ONCE() in tracepoint_remove_func().
Fix the error path by adding the missing part of cleanup.
While at this, introduce osnoise_unhook_events() to avoid code
duplication between this error path and normal tracer disable.

--------------------------------
Mikulas asked in "Do we still need commit a0ee5ec520ed ('tmpfs: allocate
on read when stacked')?" in [1]
Lukas noticed this unusual behavior of loop device backed by tmpfs in [2].
Normally, shmem_file_read_iter() copies the ZERO_PAGE when reading
holes; but if it looks like it might be a read for "a stacking
filesystem", it allocates actual pages to the page cache, and even marks
them as dirty. And reads from the loop device do satisfy the test that
is used.
This oddity was added for an old version of unionfs, to help to limit
its usage to the limited size of the tmpfs mount involved; but about the
same time as the tmpfs mod went in (2.6.25), unionfs was reworked to
proceed differently; and the mod kept just in case others needed it.
Do we still need it? I cannot answer with more certainty than "Probably
not". It's nasty enough that we really should try to delete it; but if
a regression is reported somewhere, then we might have to revert later.
It's not quite as simple as just removing the test (as Mikulas did):
xfstests generic/013 hung because splice from tmpfs failed on page not
up-to-date and page mapping unset. That can be fixed just by marking
the ZERO_PAGE as Uptodate, which of course it is: do so in
pagecache_init() - it might be useful to others than tmpfs.
My intention, though, was to stop using the ZERO_PAGE here altogether:
surely iov_iter_zero() is better for this case? Sadly not: it relies on
clear_user(), and the x86 clear_user() is slower than its copy_user() [3].
But while we are still using the ZERO_PAGE, let's stop dirtying its
struct page cacheline with unnecessary get_page() and put_page().

Reference: https://patchwork.kernel.org/project/linux-wireless/patch/20230111175031.70…
-------------------------------
Since resplen and respoffs are signed integers sufficiently
large values of unsigned int len and offset members of RNDIS
response will result in negative values of prior variables.
This may be utilized to bypass implemented security checks
to either extract memory contents by manipulating offset or
overflow the data buffer via memcpy by manipulating both
offset and len.
Additionally assure that sum of resplen and respoffs does not
overflow so buffer boundaries are kept.

--------------------------------
commit d1a997ba4c1bf65497d956aea90de42a6398f73a upstream.
When checking for libc rseq support in the library constructor, don't
only depend on the symbols presence, check that the registration was
completed.
This targets a scenario where the libc has rseq support but it is not
wired for the current architecture in 'bits/rseq.h', we want to fallback
to our internal registration mechanism.

CVE: NA
--------------------------------
commit 17858b140bf49961b71d4e73f1c3ea9bc8e7dda0 upstream.
ecdh_set_secret() casts a void* pointer to a const u64* in order to
feed it into ecc_is_key_valid(). This is not generally permitted by
the C standard, and leads to actual misalignment faults on ARMv6
cores. In some cases, these are fixed up in software, but this still
leads to performance hits that are entirely avoidable.
So let's copy the key into the ctx buffer first, which we will do
anyway in the common case, and which guarantees correct alignment.

This turned out not to be an error in usb-storage but rather a nested
device reset attempt. That is, as the rtl8712 driver was being
unbound from a composite device in preparation for an unrelated USB
reset (that driver does not have pre_reset or post_reset callbacks),
its ->remove routine called usb_reset_device() -- thus nesting one
reset call within another.
Performing a reset as part of disconnect processing is a questionable
practice at best. However, the bug report points out that the USB
core does not have any protection against nested resets. Adding a
reset_in_progress flag and testing it will prevent such errors in the
future.

[PATCH openEuler-1.0-LTS 1/8] mm/hwpoison: do not lock page again when me_huge_page() successfully recovers
by Yongqiang Liu 11 Jan '23

from mainline-v5.13
commit ea6d0630100b285f059d0a8d8e86f38a46407536
category: bugfix
bugzilla: 188222, https://gitee.com/openeuler/kernel/issues/I69SHF
CVE: NA
--------------------------------
Currently me_huge_page() temporary unlocks page to perform some actions
then locks it again later. My testcase (which calls hard-offline on
some tail page in a hugetlb, then accesses the address of the hugetlb
range) showed that page allocation code detects this page lock on buddy
page and printed out "BUG: Bad page state" message.
check_new_page_bad() does not consider a page with __PG_HWPOISON as bad
page, so this flag works as kind of filter, but this filtering doesn't
work in this case because the "bad page" is not the actual hwpoisoned
page. So stop locking page again. Actions to be taken depend on the
page type of the error, so page unlocking should be done in ->action()
callbacks. So let's make it assumed and change all existing callbacks
that way.

This is achieved by broadcasting ARP or ND packets to all of its slave
devices on transmit side. The switch will take further actions based on
proper configuration.
A new sysctl knob "net.bonding.broadcast_arp_or_nd" is introduced which
controls the behaviour of broadcasting.

CVE: NA
--------------------------------
In kobject_get_path(), if kobj->name is changed between calls
get_kobj_path_length() and fill_kobj_path() and the length becomes
longer, then fill_kobj_path() will have an out-of-bounds bug.
The actual current problem occurs when the ixgbe probe.
In ixgbe_mii_bus_init(), if the length of netdev->dev.kobj.name
length becomes longer, out-of-bounds will occur.

We detect a performance deterioration when using Unixbench, we use the dichotomy to
locate the patch 7e66740ad725 ("MPAM / ACPI: Refactoring MPAM init process and set
MPAM ACPI as entrance"), In comparing two commit df5defd901ff ("KVM: X86: MMU: Use
the correct inherited permissions to get shadow page") and ac4dbb7554ef ("ACPI 6.x:
Add definitions for MPAM table") we get following testing result:
CMD: ./Run -c xx context1

+---------+--------------+-----------------+
+ 96 + 15238.5 + 42947.8 +
+---------+--------------+-----------------+
We found a irrefutable difference in latency sampling when using the perf tool:
HEAD:ac4dbb7554ef HEAD:df5defd901ff
45.18% [kernel] [k] ktime_get_coarse_real_ts64 -> 1.78% [kernel] [k] ktime_get_coarse_real_ts64
...
65.87 │ dmb ishld //smp_rmb()
Through ftrace we get the calltrace and and detected the number of visits of
ktime_get_coarse_real_ts64, which frequently visits tk_core->seq and
tk_core->timekeeper->tkr_mono:
- 48.86% [kernel] [k] ktime_get_coarse_real_ts64
- 5.76% ktime_get_coarse_real_ts64 #about 111437657 times per 10 seconds
- 14.70% __audit_syscall_entry
syscall_trace_enter
el0_svc_common
el0_svc_handler
+ el0_svc
- 2.85% current_time
So this may be performance degradation caused by interference when happened different
fields access, We compare .bss and .data section of this two version:
HEAD:ac4dbb7554ef
`->
ffff00000962e680 l O .bss 0000000000000110 tk_core

ffff00000957db80 l O .bss 0000000000000008 cycles_at_suspend
By comparing this two version tk_core's address: ffff00000962e680 is 128Byte aligned
but latter df5defd901ff is 64Byte aligned, the memory storage layout of tk_core has
undergone subtle changes:
HEAD:ac4dbb7554ef
`-> |<--------formmer 64Bytes---------->|<------------latter 64Byte------------->|
0xffff00000957dbc0_>|<-seq 8Bytes->|<-tkr_mono 56Bytes->|<-thr_raw 56Bytes->|<-xtime_sec 8Bytes->|
0xffff00000957dc00_>...
HEAD:df5defd901ff
`-> |<------formmer 64Bytes---->|<------------latter 64Byte-------->|
0xffff00000962e680_>|<-Other variables 64Bytes->|<-seq 8Bytes->|<-tkr_mono 56Bytes->|
0xffff00000962e6c0_>..
We testified thr_raw,xtime_sec fields interfere strongly with seq,tkr_mono field because of
frequent load/store operation, this will cause as known false sharing.
We add a 64Bytes padding field in tk_core for reservation of any after usefull usage and
keep tk_core 128Byte aligned, this can avoid changes in the way tk_core's layout is stored,
In this solution, layout of tk_core always like this:
crash> struct -o tk_core_t
struct tk_core_t {
[0] u64 padding[8];
[64] seqcount_t seq;
[72] struct timekeeper timekeeper;
}
SIZE: 336
crash> struct -o timekeeper
struct timekeeper {
[0] struct tk_read_base tkr_mono;
[56] struct tk_read_base tkr_raw;
[112] u64 xtime_sec;
[120] unsigned long ktime_sec;
...
}
SIZE: 264

[PATCH openEuler-5.10-LTS 1/9] xfs: get rid of assert from xfs_btree_islastblock

commit 8c25febf23963431686f04874b96321288504127
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I4KIAO
CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
xfs_btree_check_block contains debugging knobs. With XFS_DEBUG setting up,
turn on the debugging knob can trigger the assert of xfs_btree_islastblock,
test script as follows:
while true
do
mount $disk $mountpoint
fsstress -d $testdir -l 0 -n 10000 -p 4 >/dev/null
echo 1 > /sys/fs/xfs/sda/errortag/btree_chk_sblk
sleep 10
umount $mountpoint
done
Kick off fsstress and only *then* turn on the debugging knob. If it
happens that the knob gets turned on after the cntbt lookup succeeds
but before the call to xfs_btree_islastblock, then we *can* end up in
the situation where a previously checked btree block suddenly starts
returning EFSCORRUPTED from xfs_btree_check_block. Kaboom.
Darrick give a very detailed explanation as follows:
Looking back at commit 27d9ee577dcce, I think the point of all this was
to make sure that the cursor has actually performed a lookup, and that
the btree block at whatever level we're asking about is ok.
If the caller hasn't ever done a lookup, the bc_levels array will be
empty, so cur->bc_levels[level].bp pointer will be NULL. The call to
xfs_btree_get_block will crash anyway, so the "ASSERT(block);" part is
pointless.
If the caller did a lookup but the lookup failed due to block
corruption, the corresponding cur->bc_levels[level].bp pointer will also
be NULL, and we'll still crash. The "ASSERT(xfs_btree_check_block);"
logic is also unnecessary.
If the cursor level points to an inode root, the block buffer will be
incore, so it had better always be consistent.
If the caller ignores a failed lookup after a successful one and calls
this function, the cursor state is garbage and the assert wouldn't have
tripped anyway. So get rid of the assert.
Fixes: 27d9ee577dcc ("xfs: actually check xfs_btree_check_block return in xfs_btree_islastblock")

CVE: CVE-2022-3424
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit?i…
--------------------------------
In some bad situation, the gts may be freed gru_check_chiplet_assignment.
The call chain can be gru_unload_context->gru_free_gru_context->gts_drop
and kfree finally. However, the caller didn't know if the gts is freed
or not and use it afterwards. This will trigger a Use after Free bug.
Fix it by introducing a return value to see if it's in error path or not.
Free the gts in caller if gru_check_chiplet_assignment check failed.

[PATCH openEuler-5.10 01/45] block: fix crash on cmpxchg for request_wrapper

category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I65K8D
CVE: NA
--------------------------------
Now that address of request_wrapper is caculated by address of request
plus cmd_size, if cmd_size is not aligned to 8 bytes, request_wrapper
will end up not aligned to 8 bytes as well, which will crash in arm64
because assembly instruction casal requires that operand address is
aligned to 8 bytes:
Internal error: Oops: 96000021 [#1] SMP
pc : blk_account_io_latency+0x54/0x134
Call trace:
blk_account_io_latency+0x54/0x134
blk_account_io_done+0x3c/0x4c
__blk_mq_end_request+0x78/0x134

scsi_softirq_done+0x90/0x180
blk_mq_complete_request+0x5c/0x70
scsi_mq_done+0x4c/0x100
Fix the problem by declaring request_wrapper as aligned to cachline, and
placing it before request.

category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I6694U
CVE: CVE-2022-3108
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
As the possible failure of the allocation, kmemdup() may return NULL
pointer.
Therefore, it should be better to check the 'props2' in order to prevent
the dereference of NULL pointer.

+==============================================
+SSSRAID - 3SNIC SCSI RAID Controller driver
+==============================================
+
+This file describes the SSSRAID SCSI driver for 3SNIC
+(http://www.3snic.com) RAID controllers. The SSSRAID
+driver is the first generation RAID driver for 3SNIC Corp.
+
+For 3SNIC SSSRAID controller support, enable the SSSRAID driver
+when configuring the kernel.
+
+SSSRAID specific entries in /sys
+=================================
+
+SSSRAID host attributes
+------------------------
+ - /sys/class/scsi_host/host*/csts_pp
+ - /sys/class/scsi_host/host*/csts_shst
+ - /sys/class/scsi_host/host*/csts_cfs
+ - /sys/class/scsi_host/host*/csts_rdy
+ - /sys/class/scsi_host/host*/fw_version
+
+ The host csts_pp attribute is a read only attribute. This attribute
+ indicates whether the controller is processing commands. If this attribute
+ is set to ‘1’, then the controller is processing commands normally. If
+ this attribute is cleared to ‘0’, then the controller has temporarily stopped
+ processing commands in order to handle an event (e.g., firmware activation).
+
+ The host csts_shst attribute is a read only attribute. This attribute
+ indicates status of shutdown processing.The shutdown status values are defined
+ as:
+ ====== ==============================
+ Value Definition
+ ====== ==============================
+ 00b Normal operation
+ 01b Shutdown processing occurring
+ 10b Shutdown processing complete
+ 11b Reserved
+ ====== ==============================
+ The host csts_cfs attribute is a read only attribute. This attribute is set to
+ ’1’ when a fatal controller error occurred that could not be communicated in the
+ appropriate Completion Queue. This bit is cleared to ‘0’ when a fatal controller
+ error has not occurred.
+
+ The host csts_rdy attribute is a read only attribute. This attribute is set to
+ ‘1’ when the controller is ready to process submission queue entries.
+
+ The fw_version attribute is read-only and will return the driver version and the
+ controller firmware version.
+
+SSSRAID scsi device attributes
+------------------------------
+ - /sys/class/scsi_device/X\:X\:X\:X/device/raid_level
+ - /sys/class/scsi_device/X\:X\:X\:X/device/raid_state
+ - /sys/class/scsi_device/X\:X\:X\:X/device/raid_resync
+
+ The device raid_level attribute is a read only attribute. This attribute indicates
+ RAID level of scsi device(will dispaly "NA" if scsi device is not virtual disk type).
+
+ The device raid_state attribute is read-only and indicates RAID status of scsi
+ device(will dispaly "NA" if scsi device is not virtual disk type).
+
+ The device raid_resync attribute is read-only and indicates RAID rebuild processing
+ of scsi device(will dispaly "NA" if scsi device is not virtual disk type).

+==============================================
+SSSRAID - 3SNIC SCSI RAID Controller driver
+==============================================
+
+This file describes the SSSRAID SCSI driver for 3SNIC
+(http://www.3snic.com) RAID controllers. The SSSRAID
+driver is the first generation RAID driver for 3SNIC Corp.
+
+For 3SNIC SSSRAID controller support, enable the SSSRAID driver
+when configuring the kernel.
+
+SSSRAID specific entries in /sys
+=================================
+
+SSSRAID host attributes
+------------------------
+ - /sys/class/scsi_host/host*/csts_pp
+ - /sys/class/scsi_host/host*/csts_shst
+ - /sys/class/scsi_host/host*/csts_cfs
+ - /sys/class/scsi_host/host*/csts_rdy
+ - /sys/class/scsi_host/host*/fw_version
+
+ The host csts_pp attribute is a read only attribute. This attribute
+ indicates whether the controller is processing commands. If this attribute
+ is set to ‘1’, then the controller is processing commands normally. If
+ this attribute is cleared to ‘0’, then the controller has temporarily stopped
+ processing commands in order to handle an event (e.g., firmware activation).
+
+ The host csts_shst attribute is a read only attribute. This attribute
+ indicates status of shutdown processing.The shutdown status values are defined
+ as:
+ ====== ==============================
+ Value Definition
+ ====== ==============================
+ 00b Normal operation
+ 01b Shutdown processing occurring
+ 10b Shutdown processing complete
+ 11b Reserved
+ ====== ==============================
+ The host csts_cfs attribute is a read only attribute. This attribute is set to
+ ’1’ when a fatal controller error occurred that could not be communicated in the
+ appropriate Completion Queue. This bit is cleared to ‘0’ when a fatal controller
+ error has not occurred.
+
+ The host csts_rdy attribute is a read only attribute. This attribute is set to
+ ‘1’ when the controller is ready to process submission queue entries.
+
+ The fw_version attribute is read-only and will return the driver version and the
+ controller firmware version.
+
+SSSRAID scsi device attributes
+------------------------------
+ - /sys/class/scsi_device/X\:X\:X\:X/device/raid_level
+ - /sys/class/scsi_device/X\:X\:X\:X/device/raid_state
+ - /sys/class/scsi_device/X\:X\:X\:X/device/raid_resync
+
+ The device raid_level attribute is a read only attribute. This attribute indicates
+ RAID level of scsi device(will dispaly "NA" if scsi device is not virtual disk type).
+
+ The device raid_state attribute is read-only and indicates RAID status of scsi
+ device(will dispaly "NA" if scsi device is not virtual disk type).
+
+ The device raid_resync attribute is read-only and indicates RAID rebuild processing
+ of scsi device(will dispaly "NA" if scsi device is not virtual disk type).
+

[PATCH openEuler-5.10-LTS] wifi: wilc1000: validate length of IEEE80211_P2P_ATTR_CHANNEL_LIST attribute

from stable-v5.10.157
commit 5a068535c0073c8402aa0755e8ef259fb98a33c5
category: bugfix
bugzilla: 188173 https://gitee.com/src-openeuler/kernel/issues/I66M3J
CVE: CVE-2022-47521
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
commit f9b62f9843c7b0afdaecabbcebf1dbba18599408 upstream.
Validate that the IEEE80211_P2P_ATTR_CHANNEL_LIST attribute contains
enough space for a 'struct wilc_attr_oper_ch'. If the attribute is too
small then it can trigger an out-of-bounds write later in the function.
'struct wilc_attr_oper_ch' is variable sized so also check 'attr_len'
does not extend beyond the end of 'buf'.

[PATCH openEuler-5.10-LTS 1/6] drm/amdkfd: Check for null pointer after calling kmemdup
by Zheng Zengkai 28 Dec '22

stable inclusion
from stable-v6.0.14
commit abfaf0eee97925905e742aa3b0b72e04a918fa9e
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I6694U
CVE: CVE-2022-3108
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id…
--------------------------------
As the possible failure of the allocation, kmemdup() may return NULL
pointer.
Therefore, it should be better to check the 'props2' in order to prevent
the dereference of NULL pointer.

[PATCH openEuler-1.0-LTS] dm thin: Use last transaction's pmd->root when commit failed

commit 7991dbff6849f67e823b7cc0c15e5a90b0549b9f
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I65M32
CVE: NA
--------------------------------
Recently we found a softlock up problem in dm thin pool btree lookup
code due to corrupted metadata:
Kernel panic - not syncing: softlockup: hung tasks
CPU: 7 PID: 2669225 Comm: kworker/u16:3
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996)
Workqueue: dm-thin do_worker [dm_thin_pool]
Call Trace:

Following process may generate a broken btree mixed with fresh and
stale btree nodes, which could get dm thin trapped in an infinite loop
while looking up data block:
Transaction 1: pmd->root = A, A->B->C // One path in btree
pmd->root = X, X->Y->Z // Copy-up
Transaction 2: X,Z is updated on disk, Y write failed.
// Commit failed, dm thin becomes read-only.
process_bio_read_only
dm_thin_find_block
__find_block
dm_btree_lookup(pmd->root)
The pmd->root points to a broken btree, Y may contain stale node
pointing to any block, for example X, which gets dm thin trapped into
a dead loop while looking up Z.
Fix this by setting pmd->root in __open_metadata(), so that dm thin
will use the last transaction's pmd->root if commit failed.

[PATCH openEuler-1.0-LTS] media: dvb-core: Fix UAF due to refcount races at releasing

From: Takashi Iwai <tiwai(a)suse.de>
stable inclusion
from stable-v6.1.1
commit fd3d91ab1c6ab0628fe642dd570b56302c30a792
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I5SDE4
CVE: CVE-2022-41218
--------------------------------
The dvb-core tries to sync the releases of opened files at
dvb_dmxdev_release() with two refcounts: dvbdev->users and
dvr_dvbdev->users. A problem is present in those two syncs: when yet
another dvb_demux_open() is called during those sync waits,
dvb_demux_open() continues to process even if the device is being
closed. This includes the increment of the former refcount, resulting
in the leftover refcount after the sync of the latter refcount at
dvb_dmxdev_release(). It ends up with use-after-free, since the
function believes that all usages were gone and releases the
resources.
This patch addresses the problem by adding the check of dmxdev->exit
flag at dvb_demux_open(), just like dvb_dvr_open() already does. With
the exit flag check, the second call of dvb_demux_open() fails, hence
the further corruption can be avoided.
Also for avoiding the races of the dmxdev->exit flag reference, this
patch serializes the dmxdev->exit set up and the sync waits with the
dmxdev->mutex lock at dvb_dmxdev_release(). Without the mutex lock,
dvb_demux_open() (or dvb_dvr_open()) may run concurrently with
dvb_dmxdev_release(), which allows to skip the exit flag check and
continue the open process that is being closed.
CVE-2022-41218 is assigned to those bugs above.

[PATCH openEuler-1.0-LTS] drm/amdkfd: Check for null pointer after calling kmemdup
by Yongqiang Liu 22 Dec '22
by Yongqiang Liu 22 Dec '22
22 Dec '22
From: Jiasheng Jiang <jiasheng(a)iscas.ac.cn>
stable inclusion
from stable-v6.0.14
commit abfaf0eee97925905e742aa3b0b72e04a918fa9e
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I6694U
CVE: CVE-2022-3108
--------------------------------
As the possible failure of the allocation, kmemdup() may return NULL
pointer.
Therefore, it should be better to check the 'props2' in order to prevent
the dereference of NULL pointer.

[PATCH openEuler-1.0-LTS 1/4] Bluetooth: L2CAP: Fix use-after-free caused by l2cap_chan_put

commit d0be8347c623e0ac4202a1d4e0373882821f56b0
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I64WCC
CVE: CVE-2022-20566
--------------------------------
commit d0be8347c623e0ac4202a1d4e0373882821f56b0 upstream.
This fixes the following trace which is caused by hci_rx_work starting up
*after* the final channel reference has been put() during sock_close() but
*before* the references to the channel have been destroyed, so instead
the code now rely on kref_get_unless_zero/l2cap_chan_hold_unless_zero to
prevent referencing a channel that is about to be destroyed.
refcount_t: increment on 0; use-after-free.

[PATCH openEuler-5.10 1/2] block: fix crash on cmpxchg for request_wrapper

bugzilla: https://gitee.com/openeuler/kernel/issues/I65K8D
CVE: NA
--------------------------------
Now that address of request_wrapper is caculated by address of request
plus cmd_size, if cmd_size is not aligned to 8 bytes, request_wrapper
will end up not aligned to 8 bytes as well, which will crash in arm64
because assembly instruction casal requires that operand address is
aligned to 8 bytes:
Internal error: Oops: 96000021 [#1] SMP
pc : blk_account_io_latency+0x54/0x134
Call trace:
blk_account_io_latency+0x54/0x134
blk_account_io_done+0x3c/0x4c
__blk_mq_end_request+0x78/0x134

scsi_softirq_done+0x90/0x180
blk_mq_complete_request+0x5c/0x70
scsi_mq_done+0x4c/0x100
Fix the problem by declaring request_wrapper as aligned to cachline, and
placing it before request.

When a cfs_rq throttled by qos, mark cfs_rq->throttled as 1,
and cfs bw will unthrottled this cfs_rq by mistake, it cause
a list_del_valid warning.
So add macro QOS_THROTTLED(=2), when a cfs_rq is throttled by
qos, we mark the cfs_rq->throttled as QOS_THROTTLED, will check
the value of cfs_rq->throttled before unthrottle a cfs_rq.

[PATCH openEuler-1.0-LTS 1/3] xen/netback: Ensure protocol headers don't fall in the non-linear area

commit ad7f402ae4f466647c3a669b8a6f3e5d4271c84a
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I651EB
CVE: CVE-2022-3643
--------------------------------
In some cases, the frontend may send a packet where the protocol headers
are spread across multiple slots. This would result in netback creating
an skb where the protocol headers spill over into the non-linear area.
Some drivers and NICs don't handle this properly resulting in an
interface reset or worse.
This issue was introduced by the removal of an unconditional skb pull in
the tx path to improve performance. Fix this without reintroducing the
pull by setting up grant copy ops for as many slots as needed to reach
the XEN_NETBACK_TX_COPY_LEN size. Adjust the rest of the code to handle
multiple copy operations per skb.
This is XSA-423 / CVE-2022-3643.

[PATCH openEuler-1.0-LTS] arm64: fix a concurrency issue in emulation_proc_handler()
by Yongqiang Liu 16 Dec '22
by Yongqiang Liu 16 Dec '22
16 Dec '22
From: ruanjinjie <ruanjinjie(a)huawei.com>
hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I65T0J
CVE: NA
-------------------------------
In emulation_proc_handler(), read and write operations are performed on
insn->current_mode. In the concurrency scenario, mutex only protects
writing insn->current_mode, and not protects the read. Suppose there are
two concurrent tasks, task1 updates insn->current_mode to INSN_EMULATE
in the critical section, the prev_mode of task2 is still the old data
INSN_UNDEF of insn->current_mode. As a result, two tasks call
update_insn_emulation_mode twice with prev_mode = INSN_UNDEF and
current_mode = INSN_EMULATE, then call register_emulation_hooks twice,
resulting in a list_add double problem.
Call trace:

-------------------------------
When a cfs_rq throttled by qos, mark cfs_rq->throttled as 1,
and cfs bw will unthrottled this cfs_rq by mistake, it cause
a list_del_valid warning.
So add macro QOS_THROTTLED(=2), when a cfs_rq is throttled by
qos, we mark the cfs_rq->throttled as QOS_THROTTLED, will check
the value of cfs_rq->throttled before unthrottle a cfs_rq.

it needs to notify the user space to stop ring doorbell.

[PATCH openEuler-5.10 1/5] arm64: fix a concurrency issue in emulation_proc_handler()
by Zheng Zengkai 13 Dec '22
by Zheng Zengkai 13 Dec '22

From: ruanjinjie <ruanjinjie(a)huawei.com>
hulk inclusion
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I65RG3?from=project-issue
CVE: NA
-------------------------------
In emulation_proc_handler(), read and write operations are performed on
insn->current_mode. In the concurrency scenario, mutex only protects
writing insn->current_mode, and not protects the read. Suppose there are
two concurrent tasks, task1 updates insn->current_mode to INSN_EMULATE
in the critical section, the prev_mode of task2 is still the old data
INSN_UNDEF of insn->current_mode. As a result, two tasks call
update_insn_emulation_mode twice with prev_mode = INSN_UNDEF and
current_mode = INSN_EMULATE, then call register_emulation_hooks twice,
resulting in a list_add double problem.

[PATCH openEuler-5.10-LTS 01/23] mm/dynamic_hugetlb: fix compound_nr incorrect

bugzilla: https://gitee.com/openeuler/kernel/issues/I641XX
CVE: NA
--------------------------------
Patch 1378a5ee451a ("mm: store compound_nr as well as compound_order") add
a new member compound_nr in struct page, and use this new member insteal
of compound_order in hugetlb_cgroup_move_parent() to compute the nr_pages.
In free_hugepage_to_hugetlb(), we reset page->mapping to NULL for each
subpage. Since page->mapping and page->compound_nr is union, we reset
page->compound_nr too unexpectly. This will finally result the nr_pages
incorrect in hugetlb_cgroup_move_parent() and can't release hugetlb_cgroup.
Fix this problem by reset page->compound_nr using set_compound_order().

[PATCH openEuler-1.0-LTS 1/3] USB: add usb_control_msg_send() and usb_control_msg_recv()

category: bugfix
bugzilla: 188090, https://gitee.com/src-openeuler/kernel/issues/I6068W
CVE: CVE-2022-3903
--------------------------------
New core functions to make sending/receiving USB control messages easier
and saner.
In discussions, it turns out that the large majority of users of
usb_control_msg() do so in potentially incorrect ways. The most common
issue is where a "short" message is received, yet never detected
properly due to "incorrect" error handling.
Handle all of this in the USB core with two new functions to try to make
working with USB control messages simpler.
No more need for dynamic data, messages can be on the stack, and only
"complete" send/receive will work without causing an error.

solve CVE. Commit USB: core: drop pipe-type check from new
control-message helpers is also added.

Hi All,
最近我发现openEuler-22.03-LTS分支加入了大量新特性的补丁, 比如ksmbd,
coresight和LoongArch.
这是否意味着除了fix相关的补丁,openEuler LTS版本是可以加入新特性补丁?
Thanks,

[PATCH openEuler-1.0-LTS 1/2] l2tp: Serialize access to sk_user_data with sk_callback_lock
by Yongqiang Liu 05 Dec '22
by Yongqiang Liu 05 Dec '22
05 Dec '22
From: Jakub Sitnicki <jakub(a)cloudflare.com>

from mainline-v6.1-rc6
commit b68777d54fac21fc833ec26ea1a2a84f975ab035
category: bugfix
bugzilla: 188056, https://gitee.com/src-openeuler/kernel/issues/I62RNU
CVE: CVE-2022-4129
--------------------------------
sk->sk_user_data has multiple users, which are not compatible with each
other. Writers must synchronize by grabbing the sk->sk_callback_lock.
l2tp currently fails to grab the lock when modifying the underlying tunnel
socket fields. Fix it by adding appropriate locking.
We err on the side of safety and grab the sk_callback_lock also inside the
sk_destruct callback overridden by l2tp, even though there should be no
refs allowing access to the sock at the time when sk_destruct gets called.
v4:
- serialize write to sk_user_data in l2tp sk_destruct
v3:
- switch from sock lock to sk_callback_lock
- document write-protection for sk_user_data
v2:
- update Fixes to point to origin of the bug
- use real names in Reported/Tested-by tags

occurs, and the BIOS will mark the corresponding area (for example, 2 MB)
as unusable. When the system restarts next time, these areas are not
reported or reported as EFI_UNUSABLE_MEMORY. Both cases lead to an
increase in the number of memblocks, whereas EFI_UNUSABLE_MEMORY leads to
a larger number of memblocks.
For example, if the EFI_UNUSABLE_MEMORY type is reported:
...

The EFI memory map is parsed to construct the memblock arrays before the
memblock arrays can be resized. As the result, memory regions beyond
INIT_MEMBLOCK_REGIONS are lost.
Add a new macro INIT_MEMBLOCK_MEMORY_REGIONS to replace
INIT_MEMBLOCK_REGTIONS to define the size of the static memblock.memory
array.
Allow overriding memblock.memory array size with architecture defined
INIT_MEMBLOCK_MEMORY_REGIONS and make arm64 to set
INIT_MEMBLOCK_MEMORY_REGIONS to 1024 when CONFIG_EFI is enabled.

-------------------------------
In Ascend, we use tmp hugepage and disable OOM-killer, when we cause a OOM,
and after some time, the memory is enough for process, the process will not
return to run normal. In this case, we must use oom recover to let the
process run.

--------------------------------
[ Upstream commit ec4eb8a86ade4d22633e1da2a7d85a846b7d1798 ]
When a slip driver is detaching, the slip_close() will act to
cleanup necessary resources and sl->tty is set to NULL in
slip_close(). Meanwhile, the packet we transmit is blocked,
sl_tx_timeout() will be called. Although slip_close() and
sl_tx_timeout() use sl->lock to synchronize, we don`t judge
whether sl->tty equals to NULL in sl_tx_timeout() and the
null pointer dereference bug will happen.
(Thread 1) | (Thread 2)
| slip_close()
| spin_lock_bh(&sl->lock)
| ...
... | sl->tty = NULL //(1)
sl_tx_timeout() | spin_unlock_bh(&sl->lock)
spin_lock(&sl->lock); |
... | ...
tty_chars_in_buffer(sl->tty)|
if (tty->ops->..) //(2) |
... | synchronize_rcu()
We set NULL to sl->tty in position (1) and dereference sl->tty
in position (2).
This patch adds check in sl_tx_timeout(). If sl->tty equals to
NULL, sl_tx_timeout() will goto out.

Add the Maintainer & Committers list for the openEuler/kernel repository
by referring to the MAINTAINERS file of the upstream community.
It is convenient to obtain the list of Maintainers & Committers of the
openEuler/kernel based on the submitted PR or patches.
Only the of the scheduling subsystem is added to openEuler/MAINTAINERS.
This is used as a reference for other modules and subsystems.
Example:
$./scripts/get_maintainer.pl -no-l --no-rolestats
--maintainer-path=openEuler/MAINTAINERS --no-tree --no-fixes
--no-git-blame-signatures --no-git-fallback

[PATCH openEuler-1.0-LTS] x86/tsc: use topology_max_packages() in tsc watchdog check
by Yongqiang Liu 27 Nov '22
by Yongqiang Liu 27 Nov '22

bugzilla: 187942, https://gitee.com/openeuler/kernel/issues/I5U037
CVE: NA
-------------------------------
Commit b50db7095fe0 ("x86/tsc: Disable clocksource watchdog for TSC
on qualified platorms") was introduced to solve problem that
sometimes TSC clocksource is wrongly judged as unstable by watchdog
like 'jiffies', HPET, etc.
In it, the hardware socket number is a key factor for judging
whether to disable the watchdog for TSC, and 'nr_online_nodes' was
chosen as an estimation due to it is needed in early boot phase
before registering 'tsc-early' clocksource, where all none-boot
CPUs are not brought up yet.
In recent patch review, Dave Hansen pointed out there are many
cases that 'nr_online_nodes' could have issue, like:
* numa emulation (numa=fake=4 etc.)
* numa=off
* platforms with CPU+DRAM nodes, CPU-less HBM nodes, CPU-less
persistent memory nodes.
Peter Zijlstra suggested to use logical package ids, but it is
only usable after smp_init() and all CPUs are initialized.
One solution is to skip the watchdog for 'tsc-early' clocksource,
and move the check after smp_init(), while before 'tsc'
clocksoure is registered, where topology_max_packages() could
be used as a much more accurate socket number.

[PATCH openEuler-1.0-LTS 1/2] ext4: fix bug in extents parsing when eh_entries == 0 and eh_depth > 0
by Yongqiang Liu 26 Nov '22

From: Luís Henriques <lhenriques(a)suse.de>
mainline inclusion
from mainline-v6.0-rc7
commit 29a5b8a137ac8eb410cc823653a29ac0e7b7e1b0
category: bugfix
bugzilla: 187444, https://gitee.com/openeuler/kernel/issues/I6261Z
CVE: NA
--------------------------------
When walking through an inode extents, the ext4_ext_binsearch_idx() function
assumes that the extent header has been previously validated. However, there
are no checks that verify that the number of entries (eh->eh_entries) is
non-zero when depth is > 0. And this will lead to problems because the
EXT_FIRST_INDEX() and EXT_LAST_INDEX() will return garbage and result in this:

CVE: NA
Intel-SIG: mm: Fix kabi change caused by saved_auxv[] in mm_struct for x86_64.
--------------------------------
Use the KABI_DEPRECATE and KABI_USE macro to fix kabi change caused
by commit 1c33bb050750 ("x86/elf: Support a new ELF aux vector AT_MINSIGSTKSZ").
The extended saved_auxv[] causes the kabi breakage, move the saved_auxv[]
to the end of struct mm_struct.
To avoid introducing too many size increase of mm_struct, use a pointer
to indirectly reference the relocated saved_auxv[], then adapt the code
where mm->saved_auxv is used.

hulk inclusion
category: bugfix
bugzilla: 187584, https://gitee.com/openeuler/kernel/issues/I5QW2R
CVE: NA
--------------------------------
This reverts commit 37838982c0e97898780682980aaf10755625630e.
There are two wbt_enable_default() in bfq_exit_queue(). Although it will
not lead to no fault, revert one.

With the increase of memory capacity and density, the probability of
memory error increases. The increasing size and density of server RAM
in the data center and cloud have shown increased uncorrectable memory
errors.
Currently, the kernel has a mechanism to recover from hardware memory
errors. This patchset provides an new recovery mechanism.
For arm64, the hardware memory error handling is do_sea() which divided
into two cases:
1. The user state consumed the memory errors, the solution is kill the
user process and isolate the error page.
2. The kernel state consumed the memory errors, the solution is panic.
For case 2, Undifferentiated panic maybe not the optimal choice, it can be
handled better, in some scenarios, we can avoid panic, such as uaccess, if the
uaccess fails due to memory error, only the user process will be affected,
kill the user process and isolate the user page with hardware memory errors
is a better choice.
v1 -> v2:
Integrated bugfix patchs into the fixed patch.

CVE: NA
--------------------------------
Include additional files and add new function will cause kabi broken. So move changes to blk-mq.h. bio_issue_as_root_blkg() is needed by blk_cgroup_mergeable(), move it together. It is used by iocost, too, so add blk-mq.h to blk-iocost.c.

[PATCH OLK-5.10] mm: Fix kabi change caused by saved_auxv[] in mm_struct for x86_64

CVE: NA
Intel-SIG: mm: Fix kabi change caused by saved_auxv[] in mm_struct for x86_64.
--------------------------------
Use the KABI_DEPRECATE and KABI_USE macro to fix kabi change caused by
commit 1c33bb050750 ("x86/elf: Support a new ELF aux vector AT_MINSIGSTKSZ").
The extended saved_auxv[] causes the kabi breakage, move the saved_auxv[]
to the end of struct mm_struct.
To avoid introducing too many size increase of mm_struct, use a pointer to
indirectly reference the relocated saved_auxv[], then adapt the code where
mm->saved_auxv is used.

--------------------------------
This provides the ability for architectures to enable kernel stack base
address offset randomization. This feature is controlled by the boot
param "randomize_kstack_offset=on/off", with its default value set by
CONFIG_RANDOMIZE_KSTACK_OFFSET_DEFAULT.
This feature is based on the original idea from the last public release
of PaX's RANDKSTACK feature: https://pax.grsecurity.net/docs/randkstack.txt
All the credit for the original idea goes to the PaX team. Note that
the design and implementation of this upstream randomize_kstack_offset
feature differs greatly from the RANDKSTACK feature (see below).
Reasoning for the feature:
This feature aims to make harder the various stack-based attacks that
rely on deterministic stack structure. We have had many such attacks in
past (just to name few):
https://jon.oberheide.org/files/infiltrate12-thestackisback.pdf
https://jon.oberheide.org/files/stackjacking-infiltrate11.pdf
https://googleprojectzero.blogspot.com/2016/06/exploiting-recursion-in-linu…
As Linux kernel stack protections have been constantly improving
(vmap-based stack allocation with guard pages, removal of thread_info,
STACKLEAK), attackers have had to find new ways for their exploits
to work. They have done so, continuing to rely on the kernel's stack
determinism, in situations where VMAP_STACK and THREAD_INFO_IN_TASK_STRUCT
were not relevant. For example, the following recent attacks would have
been hampered if the stack offset was non-deterministic between syscalls:
https://repositorio-aberto.up.pt/bitstream/10216/125357/2/374717.pdf
(page 70: targeting the pt_regs copy with linear stack overflow)
https://a13xp0p0v.github.io/2020/02/15/CVE-2019-18683.html
(leaked stack address from one syscall as a target during next syscall)
The main idea is that since the stack offset is randomized on each system
call, it is harder for an attack to reliably land in any particular place
on the thread stack, even with address exposures, as the stack base will
change on the next syscall. Also, since randomization is performed after
placing pt_regs, the ptrace-based approach[1] to discover the randomized
offset during a long-running syscall should not be possible.
Design description:
During most of the kernel's execution, it runs on the "thread stack",
which is pretty deterministic in its structure: it is fixed in size,
and on every entry from userspace to kernel on a syscall the thread
stack starts construction from an address fetched from the per-cpu
cpu_current_top_of_stack variable. The first element to be pushed to the
thread stack is the pt_regs struct that stores all required CPU registers
and syscall parameters. Finally the specific syscall function is called,
with the stack being used as the kernel executes the resulting request.
The goal of randomize_kstack_offset feature is to add a random offset
after the pt_regs has been pushed to the stack and before the rest of the
thread stack is used during the syscall processing, and to change it every
time a process issues a syscall. The source of randomness is currently
architecture-defined (but x86 is using the low byte of rdtsc()). Future
improvements for different entropy sources is possible, but out of scope
for this patch. Further more, to add more unpredictability, new offsets
are chosen at the end of syscalls (the timing of which should be less
easy to measure from userspace than at syscall entry time), and stored
in a per-CPU variable, so that the life of the value does not stay
explicitly tied to a single task.
As suggested by Andy Lutomirski, the offset is added using alloca()
and an empty asm() statement with an output constraint, since it avoids
changes to assembly syscall entry code, to the unwinder, and provides
correct stack alignment as defined by the compiler.
In order to make this available by default with zero performance impact
for those that don't want it, it is boot-time selectable with static
branches. This way, if the overhead is not wanted, it can just be
left turned off with no performance impact.
The generated assembly for x86_64 with GCC looks like this:
...
ffffffff81003977: 65 8b 05 02 ea 00 7f mov %gs:0x7f00ea02(%rip),%eax
# 12380 <kstack_offset>
ffffffff8100397e: 25 ff 03 00 00 and $0x3ff,%eax
ffffffff81003983: 48 83 c0 0f add $0xf,%rax
ffffffff81003987: 25 f8 07 00 00 and $0x7f8,%eax
ffffffff8100398c: 48 29 c4 sub %rax,%rsp
ffffffff8100398f: 48 8d 44 24 0f lea 0xf(%rsp),%rax
ffffffff81003994: 48 83 e0 f0 and $0xfffffffffffffff0,%rax
...
As a result of the above stack alignment, this patch introduces about
5 bits of randomness after pt_regs is spilled to the thread stack on
x86_64, and 6 bits on x86_32 (since its has 1 fewer bit required for
stack alignment). The amount of entropy could be adjusted based on how
much of the stack space we wish to trade for security.
My measure of syscall performance overhead (on x86_64):
lmbench: /usr/lib/lmbench/bin/x86_64-linux-gnu/lat_syscall -N 10000 null
randomize_kstack_offset=y Simple syscall: 0.7082 microseconds
randomize_kstack_offset=n Simple syscall: 0.7016 microseconds
So, roughly 0.9% overhead growth for a no-op syscall, which is very
manageable. And for people that don't want this, it's off by default.
There are two gotchas with using the alloca() trick. First,
compilers that have Stack Clash protection (-fstack-clash-protection)
enabled by default (e.g. Ubuntu[3]) add pagesize stack probes to
any dynamic stack allocations. While the randomization offset is
always less than a page, the resulting assembly would still contain
(unreachable!) probing routines, bloating the resulting assembly. To
avoid this, -fno-stack-clash-protection is unconditionally added to
the kernel Makefile since this is the only dynamic stack allocation in
the kernel (now that VLAs have been removed) and it is provably safe
from Stack Clash style attacks.
The second gotcha with alloca() is a negative interaction with
-fstack-protector*, in that it sees the alloca() as an array allocation,
which triggers the unconditional addition of the stack canary function
pre/post-amble which slows down syscalls regardless of the static
branch. In order to avoid adding this unneeded check and its associated
performance impact, architectures need to carefully remove uses of
-fstack-protector-strong (or -fstack-protector) in the compilation units
that use the add_random_kstack() macro and to audit the resulting stack
mitigation coverage (to make sure no desired coverage disappears). No
change is visible for this on x86 because the stack protector is already
unconditionally disabled for the compilation unit, but the change is
required on arm64. There is, unfortunately, no attribute that can be
used to disable stack protector for specific functions.
Comparison to PaX RANDKSTACK feature:
The RANDKSTACK feature randomizes the location of the stack start
(cpu_current_top_of_stack), i.e. including the location of pt_regs
structure itself on the stack. Initially this patch followed the same
approach, but during the recent discussions[2], it has been determined
to be of a little value since, if ptrace functionality is available for
an attacker, they can use PTRACE_PEEKUSR/PTRACE_POKEUSR to read/write
different offsets in the pt_regs struct, observe the cache behavior of
the pt_regs accesses, and figure out the random stack offset. Another
difference is that the random offset is stored in a per-cpu variable,
rather than having it be per-thread. As a result, these implementations
differ a fair bit in their implementation details and results, though
obviously the intent is similar.

+=========================
+CIFSD - SMB3 Kernel Server
+=========================
+
+CIFSD is a linux kernel server which implements SMB3 protocol in kernel space
+for sharing files over network.
+
+CIFSD architecture
+==================
+
+The subset of performance related operations belong in kernelspace and
+the other subset which belong to operations which are not really related with
+performance in userspace. So, DCE/RPC management that has historically resulted
+into number of buffer overflow issues and dangerous security bugs and user
+account management are implemented in user space as ksmbd.mountd.
+File operations that are related with performance (open/read/write/close etc.)
+in kernel space (ksmbd). This also allows for easier integration with VFS
+interface for all file operations.
+
+ksmbd (kernel daemon)
+---------------------
+
+When the server daemon is started, It starts up a forker thread
+(ksmbd/interface name) at initialization time and open a dedicated port 445
+for listening to SMB requests. Whenever new clients make request, Forker
+thread will accept the client connection and fork a new thread for dedicated
+communication channel between the client and the server. It allows for parallel
+processing of SMB requests(commands) from clients as well as allowing for new
+clients to make new connections. Each instance is named ksmbd/1~n(port number)
+to indicate connected clients. Depending on the SMB request types, each new
+thread can decide to pass through the commands to the user space (ksmbd.mountd),
+currently DCE/RPC commands are identified to be handled through the user space.
+To further utilize the linux kernel, it has been chosen to process the commands
+as workitems and to be executed in the handlers of the ksmbd-io kworker threads.
+It allows for multiplexing of the handlers as the kernel take care of initiating
+extra worker threads if the load is increased and vice versa, if the load is
+decreased it destroys the extra worker threads. So, after connection is
+established with client. Dedicated ksmbd/1..n(port number) takes complete
+ownership of receiving/parsing of SMB commands. Each received command is worked
+in parallel i.e., There can be multiple clients commands which are worked in
+parallel. After receiving each command a separated kernel workitem is prepared
+for each command which is further queued to be handled by ksmbd-io kworkers.
+So, each SMB workitem is queued to the kworkers. This allows the benefit of load
+sharing to be managed optimally by the default kernel and optimizing client
+performance by handling client commands in parallel.
+
+ksmbd.mountd (user space daemon)
+--------------------------------
+
+ksmbd.mountd is userspace process to, transfer user account and password that
+are registered using ksmbd.adduser(part of utils for user space). Further it
+allows sharing information parameters that parsed from smb.conf to ksmbd in
+kernel. For the execution part it has a daemon which is continuously running
+and connected to the kernel interface using netlink socket, it waits for the
+requests(dcerpc and share/user info). It handles RPC calls (at a minimum few
+dozen) that are most important for file server from NetShareEnum and
+NetServerGetInfo. Complete DCE/RPC response is prepared from the user space
+and passed over to the associated kernel thread for the client.

When iterating through a directory, a file's name may not be
null-terminated (depending on the underlying filesystem implementation).
Modify match_pattern to take the string's length into account when matching
it against the request pattern.

commit 849f59e1a18adecf0617afc82efbfc5d126c49f8
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/849f59e1a18a
-------------------------------
The error handling in ksmbd_server_init() uses "one function to free
everything style" which is impossible to audit and leads to several
canonical bugs. When we free something that wasn't allocated it may be
uninitialized, an error pointer, freed in a different function or we
try freeing "foo->bar" when "foo" is a NULL pointer. And since the
code is impossible to audit then it leads to memory leaks.
In the ksmbd_server_init() function, every goto will lead to a crash
because we have not allocated the work queue but we call
ksmbd_workqueue_destroy() which tries to flush a NULL work queue.
Another bug is if ksmbd_init_buffer_pools() fails then it leads to a
double free because we free "work_cache" twice. A third type of bug is
that we forgot to call ksmbd_release_inode_hash() so that is a resource
leak.
A better way to write error handling is for every function to clean up
after itself and never leave things partially allocated. Then we can
use "free the last successfully allocated resource" style. That way
when someone is reading the code they can just track the last resource
in their head and verify that the goto matches what they expect.
In this patch I modified ksmbd_ipc_init() to clean up after itself and
then I converted ksmbd_server_init() to use gotos to clean up.

category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/3161ad3a717e
-------------------------------
The variable err is being initialized with a value that is never read
and it is being updated later with a new value. The initialization is
redundant and can be removed.
Addresses-Coverity: ("Unused value")

CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/02b68b2065c9
-------------------------------
Matthew suggest to change linked list of tree connect list to xarray.
It will be tree connect lookup in O(log(n)) time instead of O(n) time.

commit c250e8f5566f2e1a0ea177837520eff8e59c0b7d
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/c250e8f5566f
-------------------------------
Memory is being allocated and if veto_list is zero, the loop breaks
without cleaning up the allocated memory. In this patch, the length
check has been moved before allocation. If loop breaks, the memory isn't
allocated in the first place. Thus the memory is being protected from
leaking.

-------------------------------
Matthew pointed out that embedding struct ida into the struct is
better than having a pointer to it.
This patch initialise it statically using DEFINE_IDA() or ida_init()
and remove ksmbd_ida_alloc/free().

CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/7c3d3e99ca29
-------------------------------
To remove the file, We have parsed full pathname to divide parent path and
filename. It is a better way to get parent dentry from child dentry that
obtained by lookup with given pathname.

-------------------------------
__ksmbd_lookup_fd could decrement the reference count of
unclaimed ksmbd_file to 0 but not release this ksmbd_file.
ksmbd_file cannot be unclaimed except ksmbd_close_inode_fds(),
because ksmbd_file is only removed from the m_fp_list list
after the reference count of ksmbd_file becomes 0. And if the
count is 0, __ksmbd_lookup_fd does not use ksmbd_file found
from idr due to atomic_inc_not_zero.

CVE: NA

-------------------------------
a Windows 10 client isn't able to store files from ksmbd servers due
unknown local permission problems (code 0x8007003A) if smb3 encryption
is enabled. Windows 10 is requesting for ATTRIBUTE_SECINFO (mask 0x20)
which is not yet handled by ksmbd, this leads to a invalid response.
For now we just reintroduce the old check to avoid processing of unhandled
flags until ATTRIBUTE_SECINFO is properly handled.

Fix this by responding with STATUS_NO_MEMORY or STATUS_INVALID_PARAMETER

-------------------------------
When processing a SMB2 QUERY_DIRECTORY request,
smb2_populate_readdir_entry() is called first to fill the dot/dotdot
entries. This moves the d_info->wptr pointer but out_buf_len remains
unchanged. As a result, reserve_populate_dentry() may end up writing
past the end of the buffer since the bounds checking is done on
invalid values.

-------------------------------
The user field in the session structure is allocated when the client is
authenticated. If the client explicitly logs off, the user field is freed,
but the session is kept around in case the user reconnects. If the TCP
connection hasn't been closed and the client sends a session setup with
a PreviousSessionId set, destroy_previous_session() will be called to
check if the session needs to be cleaned up.

category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/5a0ca7700591
-------------------------------
Now that 256 bit encryption can be negotiated, update
names of the nonces to match the updated official protocol
documentation (e.g. AES_GCM_NONCE instead of AES_128GCM_NONCE)
since they apply to both 128 bit and 256 bit encryption.
update smb encryption code to set 32 byte key length and to
set gcm256/ccm256 when requested on mount.

-------------------------------
Returning TreeID=0 is valid behaviour according to [MS-SMB2] 2.2.1.2:
TreeId (4 bytes): Uniquely identifies the tree connect for the command.
This MUST be 0 for the SMB2 TREE_CONNECT Request. The TreeId can be
any unsigned 32-bit integer that is received from a previous
SMB2 TREE_CONNECT Response. TreeId SHOULD be set to 0 for the
following commands:
[...]
However, some client implementations reject it as invalid. Windows10
assigns ids starting from 1, and samba4 returns a random uint32_t
which suggests there may be other clients that consider it is
invalid behaviour.

-------------------------------
If ksmbd_vfs_getcasexattr() returns -ENOMEM, stream_buf is NULL,
it will cause null-ptr-deref when using it to copy memory. So we
need check the return value of ksmbd_vfs_getcasexattr() by comparing
with 0.

CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/ade62d8b429f
-------------------------------
When running generic/591 after smb2 leases is enable, all smb2 lease ack
requests failed in ksmbd. because cifs client seems to support only smb2
v2 lease. So cifs doesn't update lease state in ack request if epoch is
not set in smb2 lease break request from ksmbd. epoch is used for smb2
v2 leases. So this patch add smb2 create v2 lease context and set
increased epoch in smb2 lease break response.

commit 5fb68864674faa3e0a4fc767c4a87f51ece218c6
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/5fb68864674f
-------------------------------
Currently function ksmbd_neg_token_init_mech_type can kfree an
uninitialized pointer oid when the call to asn1_oid_decode fails when
vlen is out of range. All the other failure cases in function
asn1_oid_decode set *oid to NULL on an error, so fix the issue by
ensuring the vlen out of range error also nullifies the pointer.
Addresses-Coverity: ("Uninitialized pointer read")

added documentation for cifsd. There, it points to a file
named:
Documentation/configuration.txt
This confuses Kernel scripts, as they think that this is a
document within the Kernel tree, instead of a file from
some other place.
Replace it by an hyperlink to the ksmbd-tools tree, in order
to avoid false-positives.

-------------------------------
"cifsd: Fix regression in smb2_get_info" patch cause that dacl doesn't
work. windows send smb2 set info security with PROTECTED_DACL_SECINFO to
control dacl. But previous patch doesn't allow it.

category: feature

CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/a5a25a114ab2
-------------------------------
smb2_validate_credit_charge() checks the CreditCharge field in the
request is valid with regards to the payload size.
The current implementation rejects requests with CreditCharge = 0 and a
payload < 64K, even though they should be accepted.
Set CreditCharge to a minimum value of 1 to avoid rejecting such
requests. This matches what samba4 does.
Fixes share enumeration for jcifs-ng clients.

Using ->d_name can be broken due to races with rename().
So use %pd with ->d_name to print filename and In other cases,
use it under ->d_lock.

mainline inclusion
from mainline-5.15-rc1
commit 8b758859dfbe9598ba41e8b9b01e44edcc0c2fc1
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/8b758859dfbe
-------------------------------
Reorder and document on-disk and netlink structures in headers.
This is a userspace ABI to communicate data between ksmbd and user IPC
daemon using netlink. This is added to track and cache user account DB
and share configuration info from userspace.
- KSMBD_EVENT_HEARTBEAT_REQUEST(ksmbd_heartbeat)
This event is to check whether user IPC daemon is alive. If user IPC
daemon is dead, ksmbd keep existing connection till disconnecting and
new connection will be denied.
- KSMBD_EVENT_STARTING_UP(ksmbd_startup_request)
This event is to receive the information that initializes the ksmbd
server from the user IPC daemon and to start the server. The global
section parameters are given from smb.conf as initialization
information.
- KSMBD_EVENT_SHUTTING_DOWN(ksmbd_shutdown_request)
This event is to shutdown ksmbd server.
- KSMBD_EVENT_LOGIN_REQUEST/RESPONSE(ksmbd_login_request/response)
This event is to get user account info to user IPC daemon.
- KSMBD_EVENT_SHARE_CONFIG_REQUEST/RESPONSE
(ksmbd_share_config_request/response)
This event is to get net share configuration info.
- KSMBD_EVENT_TREE_CONNECT_REQUEST/RESPONSE
(ksmbd_tree_connect_request/response)
This event is to get session and tree connect info.
- KSMBD_EVENT_TREE_DISCONNECT_REQUEST(ksmbd_tree_disconnect_request)
This event is to send tree disconnect info to user IPC daemon.
- KSMBD_EVENT_LOGOUT_REQUEST(ksmbd_logout_request)
This event is to send logout request to user IPC daemon.
- KSMBD_EVENT_RPC_REQUEST/RESPONSE(ksmbd_rpc_command)
This event is to make DCE/RPC request like srvsvc, wkssvc, lsarpc,
samr to be processed in userspace.
- KSMBD_EVENT_SPNEGO_AUTHEN_REQUEST/RESPONSE
(ksmbd_spnego_authen_request/response)
This event is to make kerberos authentication to be processed in
userspace.

commit ef24c962d0f29036041a007a75bcd0f50233c83e
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/ef24c962d0f2
-------------------------------
For user namespace support, we need to pass
struct user_namespace with struct dentry
to some functions. For reducing the number
of arguments, replace the struct dentry with
struct path in these functions.

CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/4951a84f61d6
-------------------------------
There is a error handling case that passes control to label out_err
without pointer sess being assigned a value. The unassigned pointer
may be any garbage value and so the test of rc < 0 && sess maybe
true leading to sess being passed to the call to ksmbd_session_destroy.
Fix this by setting sess to NULL in this corner case.

If st->status is not SMB_DIRECT_CS_CONNECTED, It will jump done label
and accessing the uninitialized send_ctxi by smb_direct_flush_send_list
will cause kernel oops. This patch just return -ENOTCONN to avoid it.

commit 3867369ef8f760155da684e10d29e0bf9b733b48
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/3867369ef8f7
-------------------------------
This patch change data type of volatile/persistent id to u64 to make
issue from idr_find and idr_remove(). !HAS_FILE_ID check will protect
integer overflow issue from idr_find and idr_remove().

category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/45a64e8b0849
-------------------------------
the wait can be canceled by SMB2_CANCEL, SMB2_CLOSE,
SMB2_LOGOFF, disconnection or shutdown, we don't have
to use wait_event_interruptible.
And this remove the warning from Coverity:
CID 1502834 (#1 of 1): Unused value (UNUSED_VALUE)
returned_value: Assigning value from ksmbd_vfs_posix_lock_wait(flock)
to err here, but that stored value is overwritten before it can be used.

category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/58090b175271
-------------------------------
When user insert wrong password, ksmbd return STATUS_INVALID_PARAMETER
error status to client. It will make user confusing whether it is not
password problem. This patch change error status to
STATUS_LOGON_FAILURE. and return STATUS_INSUFFICIENT_RESOURCES if memory
allocation failed on session setup.

CVE: NA

-------------------------------
Support for faster packet signing (using GMAC instead of CMAC) can
now be negotiated to some newer servers, including Windows.
See MS-SMB2 section 2.2.3.17.
This patch adds support for sending the new negotiate context with two
supported signing algorithms(AES-CMAC, HMAC-SHA256).
If client add support for AES_GMAC, Server will be supported later
depend on it.

-------------------------------
Both Windows 10's SMB server and samba return STATUS_OBJECT_PATH_NOT_FOUND
when trying to access a nonexistent path.
This fixes Windows 10 File History tool. The latter relies on the server
returning STATUS_OBJECT_PATH_NOT_FOUND to figure out what part of the
target path needs to be created. Returning STATUS_OBJECT_NAME_INVALID
will make it stop and display an error to the user.

-------------------------------
ksmbd create socket with IPv6 to listen both IPv4 and IPv6 connection
from client. Server should send IP addresses of NICs through network
interface info response. If Client connection is IPv4, Server should
fill IPv4 address in response buffer. But ss_family is always PF_INET6
on IPv6 socket. So This patch add ipv6_addr_v4mapped check to know
client connection is IPv4.

If smb2_get_name() then name is an error pointer. In the clean up
code, we try to kfree() it and that will lead to an Oops. Set it to
NULL instead.

commit eebff916f07775b2ecd9186439e69a70af24630b
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/eebff916f077
-------------------------------
To negotiate either the SMB2 protocol or SMB protocol, a client must
send a SMB_COM_NEGOTIATE message containing the list of dialects it
supports, to which the server will respond with either a
SMB_COM_NEGOTIATE or a SMB2_NEGOTIATE response.
The current implementation responds with the highest common dialect,
rather than looking explicitly for "SMB 2.???" and "SMB 2.002", as
indicated in [MS-SMB2]:
[MS-SMB2] 3.3.5.3.1:
If the server does not implement the SMB 2.1 or 3.x dialect family,
processing MUST continue as specified in 3.3.5.3.2.
Otherwise, the server MUST scan the dialects provided for the dialect
string "SMB 2.???". If the string is not present, continue to section
3.3.5.3.2. If the string is present, the server MUST respond with an
SMB2 NEGOTIATE Response as specified in 2.2.4.
[MS-SMB2] 3.3.5.3.2:
The server MUST scan the dialects provided for the dialect string "SMB
2.002". If the string is present, the client understands SMB2, and the
server MUST respond with an SMB2 NEGOTIATE Response.
This is an issue if a client attempts to negotiate SMB3.1.1 using
a SMB_COM_NEGOTIATE, as it will trigger the following NULL pointer
dereference:

Kernel panic - not syncing: Fatal exception
smb3_preauth_hash_rsp() panics because conn->preauth_info is only allocated
when processing a SMB2 NEGOTIATE request.
Fix this by splitting the smb_protos array into two, each containing
only SMB1 and SMB2 dialects respectively.
While here, make ksmbd_negotiate_smb_dialect() static as it not
called from anywhere else.

When commanding chmod and chown on cifs&ksmbd, ksmbd allows it without file
permissions check. There is code to check it in settattr_prepare.
Instead of setting the inode directly, update the mode and uid/gid
through notify_change.

This seems to be a false alarm because hex_attr size is always smaller
than n->length. This patch fix this warning by allocation hex_attr with
n->length.

commit db7fb6fe3d7a8eb05f2b74c6252771c9362f3b74
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/db7fb6fe3d7a
-------------------------------
Permission checking and copying over ownership information is the task
of the underlying filesystem not ksmbd. The order is also wrong here.
This modifies the inode before notify_change(). If notify_change() fails
this will have changed ownership nonetheless. All of this is unnecessary
though since the underlying filesystem's ->setattr handler will do all
this (if required) by itself.

rwlock.h specifically asks to not be included directly.
In fact, the proper spinlock.h include isn't needed either,
it comes with the huge pile that kthread.h ends up pulling
in, so just drop it entirely.

-------------------------------
Because of .., files outside the share directory
could be accessed. To prevent this, normalize
the given path and remove all . and ..
components.
In addition to the usual large set of regression tests (smbtorture
and xfstests), ran various tests on this to specifically check
path name validation including libsmb2 tests to verify path
normalization:

category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/e44fd5081c50
-------------------------------
While we are working through detailed security reviews
of ksmbd server code we should remind users that it is an
experimental module by adding a warning when the module
loads. Currently the module shows as experimental
in Kconfig and is disabled by default, but we don't want
to confuse users.
Although ksmbd passes a wide variety of the
important functional tests (since initial focus had
been largely on functional testing such as smbtorture,
xfstests etc.), and ksmbd has added key security
features (e.g. GCM256 encryption, Kerberos support),
there are ongoing detailed reviews of the code base
for path processing and network buffer decoding, and
this patch reminds users that the module should be
considered "experimental."

mainline inclusion
from mainline-5.15-rc3
commit 265fd1991c1db85fbabaad4946ca0e63e2ae688d
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/265fd1991c1d
-------------------------------
instead of removing '..' in a given path, call
kern_path with LOOKUP_BENEATH flag to prevent
the out of share access.
ran various test on this:
smb2-cat-async smb://127.0.0.1/homes/../out_of_share
smb2-cat-async smb://127.0.0.1/homes/foo/../../out_of_share
smbclient //127.0.0.1/homes -c "mkdir ../foo2"
smbclient //127.0.0.1/homes -c "rename bar ../bar"

commit 18d46769d54aba03c2c3fa666fe810f264b5d7b8
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/18d46769d54a
-------------------------------
In smb_common.c you have this function : ksmbd_smb_request() which
is called from connection.c once you have read the initial 4 bytes for
the next length+smb2 blob.
It checks the first byte of this 4 byte preamble for valid values,
i.e. a NETBIOSoverTCP SESSION_MESSAGE or a SESSION_KEEP_ALIVE.
We don't need to check this for ksmbd since it only implements SMB2
over TCP port 445.
The netbios stuff was only used in very old servers when SMB ran over
TCP port 139.
Now that we run over TCP port 445, this is actually not a NB header anymore
and you can just treat it as a 4 byte length field that must be less
than 16Mbyte. and remove the references to the RFC1002 constants that no
longer applies.

Add validation for request/response buffer size check in smb2_ioctl and
fsctl_copychunk() take copychunk_ioctl_req pointer and the other arguments
instead of smb2_ioctl_req structure and remove an unused smb2_ioctl_req
argument of fsctl_validate_negotiate_info.

-------------------------------
ksmbd limit read/write/trans buffer size not to exceed maximum 8MB.
And set the minimum value of max response buffer size to 64KB.
Windows client doesn't send session setup request if ksmbd set max
trans/read/write size lower than 64KB in smb2 negotiate.
It means windows allow at least 64 KB or more about this value.

To avoid dictionary attacks (repeated session setups rapidly sent) to
connect to server, ksmbd make a delay of a 5 seconds on session setup
failure to make it harder to send enough random connection requests
to break into a server if a user insert the wrong password 10 times
in a row.

'destroy_workqueue()' already drains the queue before destroying it, so
there is no need to flush it explicitly.
Remove the redundant 'flush_workqueue()' calls.

CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/78f1688a64cc
-------------------------------
The validate_negotiate_info_req struct definition includes an extra
field to access the data coming after the header. This causes the check
in fsctl_validate_negotiate_info() to count the first element of the
array twice. This in turn makes some valid requests fail, depending on
whether they include padding or not.

commit 1ec72153ff434ce75bace3044dc89a23a05d7064
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/1ec72153ff43
-------------------------------
If xattr is not supported like exfat or fat, ksmbd server doesn't
contain default data stream in FILE_STREAM_INFORMATION response. It will
cause ppt or doc file update issue if local filesystem is such as ones.
This patch move goto statement to contain it.
Fixes: 9f6323311c70 ("ksmbd: add default data stream name in FILE_STREAM_INFORMATION")

-------------------------------
ksmbd is forcing to turn on FS_POSIX_ACL in Kconfig to use vfs acl
functions(posix_acl_alloc, get_acl, set_posix_acl). OpenWRT and other
platform doesn't use acl and this config is disable by default in
kernel. This patch use IS_ENABLED() to know acl config is enable and use
acl function if it is enable.

commit 83912d6d55be10d65b5268d1871168b9ebe1ec4b
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/83912d6d55be
-------------------------------
According to the official Microsoft MS-SMB2 document section 3.3.5.4, this
flag should be used only for 3.0 and 3.0.2 dialects. Setting it for 3.1.1
is a violation of the specification.
This causes my Windows 10 client to detect an anomaly in the negotiation,
and disable encryption entirely despite being explicitly enabled in ksmbd,
causing all data transfers to go in plain text.

-------------------------------
Set RSS capable in FSCTL_QUERY_NETWORK_INTERFACE_INFO if netdev has
multi tx queues. And add ksmbd_compare_user() to avoid racy condition
issue in ksmbd_free_user(). because windows client is simultaneously used
to send session setup requests for multichannel connection.

-------------------------------
When RSS mode is enable, windows client do simultaneously send several
session requests to server. There is racy issue using
sess->ntlmssp.cryptkey on N connection : 1 session. So authetication
failed using wrong cryptkey on some session. This patch move cryptkey
to ksmbd_conn structure to use each cryptkey on connection.

CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/cb097b3dd5ec
-------------------------------
When SMB Direct is used with iWARP, Windows use 5445 port for smb direct
port, 445 port for SMB. This patch check ib_device using ib_client to
know if NICs type is iWARP or Infiniband.

Create a memory region pool because rdma_rw_ctx_init()
uses memory registration if memory registration yields
better performance than using multiple SGE entries.

-------------------------------
if the Channel of a SMB2 WRITE request is
SMB2_CHANNEL_RDMA_V1_INVALIDTE, a client
does not invalidate its memory regions but
ksmbd must do it by sending a SMB2 WRITE response
with IB_WR_SEND_WITH_INV.
But if errors occur while processing a SMB2
READ/WRITE request, ksmbd sends a response
with IB_WR_SEND. So a client could use memory
regions already in use.

category: feature

CVE: NA

-------------------------------
MS-SMB2 describe session sign like the following.
Session.SigningRequired MUST be set to TRUE under the following conditions:
- If the SMB2_NEGOTIATE_SIGNING_REQUIRED bit is set in the SecurityMode
field of the client request.
- If the SMB2_SESSION_FLAG_IS_GUEST bit is not set in the SessionFlags
field and Session.IsAnonymous is FALSE and either Connection.ShouldSign
or global RequireMessageSigning is TRUE.
When trying guest account connection using nautilus, The login failure
happened on session setup. ksmbd does not allow this connection
when the user is a guest and the connection sign is set. Just do not set
session sign instead of error response as described in the specification.
And this change improves the guest connection in Nautilus.

ksmbd does not support more than one Buffer Descriptor V1 element in
an smbdirect protocol request. Reducing the maximum read/write size to
about 512KB allows interoperability with Windows over a wider variety
of RDMA NICs, as an interim workaround.

commit d21a580dafc69aa04f46e6099616146a536b0724
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/d21a580dafc6
-------------------------------
The issue happens in a specific path in smb_check_perm_dacl(). When
"id" and "uid" have the same value, the function simply jumps out of
the loop without decrementing the reference count of the object
"posix_acls", which is increased by get_acl() earlier. This may
result in memory leaks.
Fix it by decreasing the reference count of "posix_acls" before
jumping to label "check_access_bits".
Fixes: 777cad1604d6 ("ksmbd: remove select FS_POSIX_ACL in Kconfig")

We found the issue that ksmbd return STATUS_NO_MORE_FILES response
even though there are still dentries that needs to be read while
file read/write test using framtest utils.
windows client send smb2 query dir request included
OutputBufferLength(128) that is too small to contain even one entry.
This patch make ksmbd immediately returns OutputBufferLength of response
as zero to client.

commit 88541cb414b7a2450c45fc9c131b37b5753b7679
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/88541cb414b7
-------------------------------
if iterate_dir() returns non-negative value, caller has to treat it
as normal and check there is any error while populating dentry
information. ksmbd doesn't have to do anything because ksmbd already
checks too small OutputBufferLength to store one file information.
And because ctx->pos is set to file->f_pos when iterative_dir is called,
remove restart_ctx(). And if iterate_dir() return -EIO, which mean
directory entry is corrupted, return STATUS_FILE_CORRUPT_ERROR error
response.
This patch fixes some failure of SMB2_QUERY_DIRECTORY, which happens when
ntfs3 is local filesystem.
Fixes: e2f34481b24d ("cifsd: add server-side procedures for SMB3")

-------------------------------
ksmbd threads eating masses of cputime when connection is disconnected.
If connection is disconnected, ksmbd thread waits for pending requests
to be processed using schedule_timeout. schedule_timeout() incorrectly
is used, and it is more efficient to use wait_event/wake_up than to check
r_count every time with timeout.

CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/17ea92a9f6d0
-------------------------------
There is a report that kernel oops happen from idr_remove().
kernel: BUG: kernel NULL pointer dereference, address: 0000000000000010
kernel: RIP: 0010:idr_remove+0x1/0x20
kernel: __ksmbd_close_fd+0xb2/0x2d0 [ksmbd]

kernel: kthread+0xee/0x120
kthread_complete_and_exit+0x20/0x20
kernel: ret_from_fork+0x22/0x30
While accessing files, If connection is disconnected, windows send
session setup request included previous session destroy. But while still
processing requests on previous session, this request destroy file
table, which mean file table idr will be freed and set to NULL.
So kernel oops happen from ft->idr in __ksmbd_close_fd().
This patch don't directly destroy session in destroy_previous_session().
It just set to KSMBD_SESS_EXITING so that connection will be
terminated after finishing the rest of requests.

-------------------------------
By not checking whether llseek is NULL, this might jump to NULL. Also,
it doesn't check FMODE_LSEEK. Fix this by using vfs_llseek(), which
always does the right thing.

commit af7c39d971e43cd0af488729bca362427ad99488
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/af7c39d971e4
-------------------------------
After multi-channel connection with windows, Several channels of
session are connected. Among them, if there is a problem in one channel,
Windows connects again after disconnecting the channel. In this process,
the session is released and a kernel oop can occurs while processing
requests to other channels. When the channel is disconnected, if other
channels still exist in the session after deleting the channel from
the channel list in the session, the session should not be released.
Finally, the session will be released after all channels are disconnected.

Reference: https://git.kernel.org/torvalds/linux/c/7c88c1e0ab17
-------------------------------
A kernel daemon should not rely on the current thread, which is unknown
and might be malicious. Before this security fix,
ksmbd_override_fsids() didn't correctly override FS UID/GID which means
that arbitrary user space threads could trick the kernel to impersonate
arbitrary users or groups for file system access checks, leading to
file system access bypass.
This was found while investigating truncate support for Landlock:

commit af705ef2b0ded0d8f54c238fdf3c17a1d47ad924
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/af705ef2b0de
-------------------------------
If client send encrypted session logoff request on seal mount,
Encryption for that response fails.
ksmbd: Could not get encryption key
CIFS: VFS: cifs_put_smb_ses: Session Logoff failure rc=-512
Session lookup fails in ksmbd_get_encryption_key() because sess->state is
set to SMB2_SESSION_EXPIRED in session logoff. There is no need to do
session lookup again to encrypt the response. This patch change to use
ksmbd_session in ksmbd_work.

-------------------------------
Commit c7803b05f74b ("smb3: fix ksmbd bigendian bug in oplock
break, and move its struct to smbfs_common") use the defination
of 'struct validate_negotiate_info_req' in smbfs_common, the
array length of 'Dialects' changed from 1 to 4, but the protocol
does not require the client to send all 4. This lead the request
which satisfied with protocol and server to fail.
So just ensure the request payload has the 'DialectCount' in
smb2_ioctl(), then fsctl_validate_negotiate_info() will use it
to validate the payload length and each dialect.
Also when the {in, out}_buf_len is less than the required, should
goto out to initialize the status in the response header.
Fixes: f7db8fd03a4b ("ksmbd: add validation in smb2_ioctl")

commit 5d2f0b1083eb158bdff01dd557e2c25046c0a7d2
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/5d2f0b1083eb
-------------------------------
Steve French reported ksmbd set fixed value to volume serial field in
FS_VOLUME_INFORMATION. Volume serial value needs to be set to a unique
value for client fscache. This patch set crc value that is generated
with share name, path name and netbios name to volume serial.
Fixes: e2f34481b24d ("cifsd: add server-side procedures for SMB3")

-------------------------------
Whenever new parameter is added to smb configuration, It is possible
to break the execution of the IPC daemon by mismatch size of
request/response. This patch tries to reserve space in ipc request/response
in advance to prevent that.

commit e2ebff9c57fe4eb104ce4768f6ebcccf76bef849
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/I60T7G
CVE: NA
Reference: https://git.kernel.org/torvalds/linux/c/e2ebff9c57fe
-------------------------------
If something manages to set the maximum file size to MAX_OFFSET+1, this
can cause the xfs and ext4 filesystems at least to become corrupt.
Ordinarily, the kernel protects against userspace trying this by
checking the value early in the truncate() and ftruncate() system calls
calls - but there are at least two places that this check is bypassed:
(1) Cachefiles will round up the EOF of the backing file to DIO block
size so as to allow DIO on the final block - but this might push
the offset negative. It then calls notify_change(), but this
inadvertently bypasses the checking. This can be triggered if
someone puts an 8EiB-1 file on a server for someone else to try and
access by, say, nfs.
(2) ksmbd doesn't check the value it is given in set_end_of_file_info()
and then calls vfs_truncate() directly - which also bypasses the
check.
In both cases, it is potentially possible for a network filesystem to
cause a disk filesystem to be corrupted: cachefiles in the client's
cache filesystem; ksmbd in the server's filesystem.
nfsd is okay as it checks the value, but we can then remove this check
too.
Fix this by adding a check to inode_newsize_ok(), as called from
setattr_prepare(), thereby catching the issue as filesystems set up to
perform the truncate with minimal opportunity for bypassing the new
check.
Fixes: 1f08c925e7a3 ("cachefiles: Implement backing file wrangling")
Fixes: f44158485826 ("cifsd: add file operations")

[PATCH openEuler-1.0-LTS] block: check flags of claimed slave bdev to fix uaf for bd_holder_dir

As explained in 0eb440122f89 ("block: fix use after free for
bd_holder_dir"), we should make sure the "disk" is still live and
then grab a reference to 'bd_holder_dir'. However, the "disk"
should be "the claimed slave bdev" rather than "the holding disk".

With the increase of memory capacity and density, the probability of
memory error increases. The increasing size and density of server RAM
in the data center and cloud have shown increased uncorrectable memory
errors.
Currently, the kernel has a mechanism to recover from hardware memory
errors. This patchset provides an new recovery mechanism.
For arm64, the hardware memory error handling is do_sea() which divided
into two cases:
1. The user state consumed the memory errors, the solution is kill the
user process and isolate the error page.
2. The kernel state consumed the memory errors, the solution is panic.
For case 2, Undifferentiated panic maybe not the optimal choice, it can be
handled better, in some scenarios, we can avoid panic, such as uaccess, if the
uaccess fails due to memory error, only the user process will be affected,
kill the user process and isolate the user page with hardware memory errors
is a better choice.

[PATCH openEuler-5.10-LTS 01/12] scsi: libsas: Resume SAS host for phy reset or enable via sysfs
by Zheng Zengkai 10 Nov '22
by Zheng Zengkai 10 Nov '22
10 Nov '22
From: Xiang Chen <chenxiang66(a)hisilicon.com>
mainline inclusion
from mainline-v5.19-rc7
commit 1e82e4627a795
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I5M9GC
CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
----------------------------------------------------------------------
Currently if a phy reset or enable phy is issued via sysfs when controller
is suspended, those operations will be ignored as SAS_HA_REGISTERED is
cleared. If RPM is enabled then we may aggressively suspend automatically.
In this case it may be difficult to enable or reset a phy via sysfs, so
resume the host in these scenarios.

[PATCH OLK-5.10,v1,0/9] ROH: Support ROH basic functions and adapt ROH mode for RDMA/hns driver
by Ke Chen 09 Nov '22
by Ke Chen 09 Nov '22
09 Nov '22
[Description]
The ROH module driver consists of the ROH Core and ROH DRV
modules, which work with hardware to implement communication
between nodes through HCCS packets.
ROH Core is a protocol stack of the ROH architecture. It provides
related services for upper layers by invoking operation interfaces
provided by the ROH DRV.
The ROH DRV implements the lower layer functions of the ROH
featureand provides a series of interfaces for operating hardware
for the ROH Core.
This patch supports basic ROH functions, such as: sysfs file node
query, abnormal interrupt handling, reset capability and dfx
information query.
RDMA/hns supports ROH mode, mainly adapted to the device id of ROH,
and the different capabilities and features of RDMA/hns in ROH mode.
[Testing]
kernel options:
CONFIG_ROH=m
CONFIG_ROH_HNS=m
Test passed with below step:
1. Using a hardware environment that supports ROH, insmod net/hns,
RDMA/hns and ROH related drivers:
insmod hnae3.ko
insmod hclge.ko
insmod hns3.ko
insmod roh_core.ko
insmod hns-roh-v1.ko
insmod hns-roce-hw-v2.ko
2. Check whether ROH generates the corresponding sysfs node:
ls /sys/class/roh/hns3_0/
3. Check whether the abnormal interrupt information of roh is correct.
The down or up of the network device link corresponding to roh will
cause the roh abnormal interrupt count to increase.
cat /proc/interrupts | grep roh
4. Configure the network port ip and check whether the ip/mac has the
correct mapping relationship.
5. Query eid to check whether it complies with ip conversion rules:
cat /sys/class/roh/hns3_0/node_eid
6. Use ping to check Ethernet communication is normal.
7. Use perftest to check RDMA communication is normal.
8. Use the "ethtool --reset eth1 all" command to trigger a reset.
