commit 336626564b58071b8980a4e6a31a8f5d92705d9b
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/ICG9AQ
CVE: CVE-2022-50103
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
[ Upstream commit b6e8d40d43ae4dec00c8fea2593eeea3114b8f44 ]
With cgroup v2, the cpuset's cpus_allowed mask can be empty indicating
that the cpuset will just use the effective CPUs of its parent. So
cpuset_can_attach() can call task_can_attach() with an empty mask.
This can lead to cpumask_any_and() returns nr_cpu_ids causing the call
to dl_bw_of() to crash due to percpu value access of an out of bound
CPU value. For example:
[80468.182258] BUG: unable to handle page fault for address: ffffffff8b6648b0
:

[80468.224287] entry_SYSCALL_64_after_hwframe+0x44/0xae
Fix that by using effective_cpus instead. For cgroup v1, effective_cpus
is the same as cpus_allowed. For v2, effective_cpus is the real cpumask
to be used by tasks within the cpuset anyway.
Also update task_can_attach()'s 2nd argument name to cs_effective_cpus to
reflect the change. In addition, a check is added to task_can_attach()
to guard against the possibility that cpumask_any_and() may return a
value >= nr_cpu_ids.

--------------------------------
[ Upstream commit 136f614931a2bb73616b292cf542da3a18daefd5 ]
The last case label can write two buffers 'mc_reg_address[j]' and
'mc_data[j]' with 'j' offset equal to SMC_NISLANDS_MC_REGISTER_ARRAY_SIZE
since there are no checks for this value in both case labels after the
last 'j++'.
Instead of changing '>' to '>=' there, add the bounds check at the start
of the second 'case' (the first one already has it).
Also, remove redundant last checks for 'j' index bigger than array size.
The expression is always false. Moreover, before or after the patch
'table->last' can be equal to SMC_NISLANDS_MC_REGISTER_ARRAY_SIZE and it
seems it can be a valid value.
Detected using the static analysis tool - Svace.

312c89fbca06896 Misono, Tomohiro 2017-12-14 1619 * In order to allow mounting a subvolume directly, btrfs uses mount_subtree()
312c89fbca06896 Misono, Tomohiro 2017-12-14 1620 * which needs vfsmount* of device's root (/). This means device's root has to
312c89fbca06896 Misono, Tomohiro 2017-12-14 1621 * be mounted internally in any case.
312c89fbca06896 Misono, Tomohiro 2017-12-14 1622 *
312c89fbca06896 Misono, Tomohiro 2017-12-14 1623 * Operation flow:

312c89fbca06896 Misono, Tomohiro 2017-12-14 1625 *
312c89fbca06896 Misono, Tomohiro 2017-12-14 1626 * 2. Mount device's root (/) by calling vfs_kern_mount().
312c89fbca06896 Misono, Tomohiro 2017-12-14 1627 *
312c89fbca06896 Misono, Tomohiro 2017-12-14 1628 * NOTE: vfs_kern_mount() is used by VFS to call btrfs_mount() in the
312c89fbca06896 Misono, Tomohiro 2017-12-14 1629 * first place. In order to avoid calling btrfs_mount() again, we use
312c89fbca06896 Misono, Tomohiro 2017-12-14 1630 * different file_system_type which is not registered to VFS by
312c89fbca06896 Misono, Tomohiro 2017-12-14 1631 * register_filesystem() (btrfs_root_fs_type). As a result,
312c89fbca06896 Misono, Tomohiro 2017-12-14 1632 * btrfs_mount_root() is called. The return value will be used by
312c89fbca06896 Misono, Tomohiro 2017-12-14 1633 * mount_subtree() in mount_subvol().
312c89fbca06896 Misono, Tomohiro 2017-12-14 1634 *
312c89fbca06896 Misono, Tomohiro 2017-12-14 1635 * 3. Call mount_subvol() to get the dentry of subvolume. Since there is
312c89fbca06896 Misono, Tomohiro 2017-12-14 1636 * "btrfs subvolume set-default", mount_subvol() is called always.
