[PATCH openEuler-1.0-LTS] clk: qcom: mmcc-msm8974: fix terminating of frequency table arrays

From: Gabor Juhos <j4g8y7(a)gmail.com> stable inclusion from stable-v5.10.215 commit 3ff4a0f6a8f0ad4b4ee9e908bdfc3cacb7be4060 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9L5N3 CVE: CVE-2024-26965 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit e2c02a85bf53ae86d79b5fccf0a75ac0b78e0c96 ] The frequency table arrays are supposed to be terminated with an empty element. Add such entry to the end of the arrays where it is missing in order to avoid possible out-of-bound access when the table is traversed by functions like qcom_find_freq() or qcom_find_freq_floor(). Only compile tested.

The source of this is when we have our commit requests to submit, we process them and send them off, and then in the completion path for the commit requests we have if (nfs_commit_end(cinfo.mds)) nfs_direct_write_complete(dreq); However since we're submitting asynchronous requests we sometimes have one that completes before we submit the next one, so we end up calling complete on the nfs_direct_request twice. The only other place we use nfs_generic_commit_list() is in __nfs_commit_inode, which wraps this call in a nfs_commit_begin(); nfs_commit_end(); Which is a common pattern for this style of completion handling, one that is also repeated in the direct code with get_dreq()/put_dreq() calls around where we process events as well as in the completion paths. Fix this by using the same pattern for the commit requests. Before with my 200 node rocksdb stress running this warning would pop every 10ish minutes. With my patch the stress test has been running for several hours without popping.

[PATCH OLK-5.10] wireguard: netlink: access device through ctx instead of peer

It's actually easier and faster performance-wise to instead get the device from ctx->wg. This semantically makes more sense too, since ctx->wg->peer_allowedips.seq is compared with ctx->allowedips_seq, basing them both in ctx. This also acts as a defence in depth provision against freed peers. Cc: stable(a)vger.kernel.org Fixes: e7096c131e51 ("net: WireGuard secure network tunnel") Signed-off-by: Jason A.

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9NC0J CVE: NA -------------------------------- The function sysctl_memcg_swap_qos_handler() doesn't handle error case correctly and care nothing about concurrency. To fix it, we should do two thing: 1. reset sysctl_memcg_swap_qos_stat to old value for error case. 2. add a mutex_lock to protect the process.

Note that if llsec_lookup_key() finds a key, it gets a refcount via llsec_key_get() and locally copies key id from key_entry (which is a list element). So it's safe to call llsec_key_put() and free the list entry after the RCU grace period elapses. Found by Linux Verification Center (linuxtesting.org).

[PATCH openEuler-1.0-LTS] netfilter: nf_tables: fix memleak in map from abort path
by Liu Jian 08 May '24

08 May '24

From: Pablo Neira Ayuso <pablo(a)netfilter.org> mainline inclusion from mainline-v6.9-rc5 commit 86a1471d7cde792941109b93b558b5dc078b9ee9 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9L5OD CVE: CVE-2024-27011 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… --------------------------- The delete set command does not rely on the transaction object for element removal, therefore, a combination of delete element + delete set from the abort path could result in restoring twice the refcount of the mapping. Check for inactive element in the next generation for the delete element command in the abort path, skip restoring state if next generation bit has been already cleared. This is similar to the activate logic using the set walk iterator.

[PATCH openEuler-1.0-LTS] USB: core: Fix deadlock in usb_deauthorize_interface()
by Ye Bin 08 May '24

08 May '24

From: Alan Stern <stern(a)rowland.harvard.edu> mainline inclusion from mainline-v6.9-rc2 commit 80ba43e9f799cbdd83842fc27db667289b3150f5 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9L5GW CVE: CVE-2024-26934 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- Among the attribute file callback routines in drivers/usb/core/sysfs.c, the interface_authorized_store() function is the only one which acquires a device lock on an ancestor device: It calls usb_deauthorize_interface(), which locks the interface's parent USB device. The will lead to deadlock if another process already owns that lock and tries to remove the interface, whether through a configuration change or because the device has been disconnected. As part of the removal procedure, device_del() waits for all ongoing sysfs attribute callbacks to complete. But usb_deauthorize_interface() can't complete until the device lock has been released, and the lock won't be released until the removal has finished. The mechanism provided by sysfs to prevent this kind of deadlock is to use the sysfs_break_active_protection() function, which tells sysfs not to wait for the attribute callback.

[PATCH openEuler-1.0-LTS v2] ima: fix deadlock when traversing "ima_default_rules".
by GUO Zihua 08 May '24

From: liqiong <liqiong(a)nfschina.com> mainline inclusion from mainline-v5.16-rc1 commit eb0782bbdfd0d7c4786216659277c3fd585afc0e category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9AAM6 CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- The current IMA ruleset is identified by the variable "ima_rules" that default to "&ima_default_rules". When loading a custom policy for the first time, the variable is updated to "&ima_policy_rules" instead. That update isn't RCU-safe, and deadlocks are possible. Indeed, some functions like ima_match_policy() may loop indefinitely when traversing "ima_default_rules" with list_for_each_entry_rcu(). When iterating over the default ruleset back to head, if the list head is "ima_default_rules", and "ima_rules" have been updated to "&ima_policy_rules", the loop condition (&entry->list != ima_rules) stays always true, traversing won't terminate, causing a soft lockup and RCU stalls. Introduce a temporary value for "ima_rules" when iterating over the ruleset to avoid the deadlocks.

The will lead to deadlock if another process already owns that lock and tries to remove the interface, whether through a configuration change or because the device has been disconnected. As part of the removal procedure, device_del() waits for all ongoing sysfs attribute callbacks to complete. But usb_deauthorize_interface() can't complete until the device lock has been released, and the lock won't be released until the removal has finished. The mechanism provided by sysfs to prevent this kind of deadlock is to use the sysfs_break_active_protection() function, which tells sysfs not to wait for the attribute callback.

[PATCH openEuler-22.03-LTS] bpf: Fix hashtab overflow check on 32-bit arches
by Pu Lehui 08 May '24

08 May '24

From: Toke Høiland-Jørgensen <toke(a)redhat.com> stable inclusion from stable-v5.10.214 commit 64f00b4df0597590b199b62a37a165473bf658a6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I9HK6X CVE: CVE-2024-26884 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 6787d916c2cf9850c97a0a3f73e08c43e7d973b1 ] The hashtab code relies on roundup_pow_of_two() to compute the number of hash buckets, and contains an overflow check by checking if the resulting value is 0. However, on 32-bit arches, the roundup code itself can overflow by doing a 32-bit left-shift of an unsigned long value, which is undefined behaviour, so it is not guaranteed to truncate neatly. This was triggered by syzbot on the DEVMAP_HASH type, which contains the same check, copied from the hashtab code. So apply the same fix to hashtab, by moving the overflow check to before the roundup.
