[PATCH OLK-6.6] fs/netfs/fscache_cookie: add missing "n_accesses" check

At the same time, yet another process invoked cachefiles_prepare_write(), which found a NULL pointer in this code line: struct cachefiles_object *object = cachefiles_cres_object(cres); The next line crashes, obviously: struct cachefiles_cache *cache = object->volume->cache; During cachefiles_prepare_write(), the "n_accesses" counter is non-zero (via fscache_begin_operation()). The cookie must not be withdrawn until it drops to zero. The counter is checked by fscache_cookie_state_machine() before switching to FSCACHE_COOKIE_STATE_RELINQUISHING and FSCACHE_COOKIE_STATE_WITHDRAWING (in "case FSCACHE_COOKIE_STATE_FAILED"), but not for FSCACHE_COOKIE_STATE_LRU_DISCARDING ("case FSCACHE_COOKIE_STATE_ACTIVE"). This patch adds the missing check. With a non-zero access counter, the function returns and the next fscache_end_cookie_access() call will queue another fscache_cookie_state_machine() call to handle the still-pending FSCACHE_COOKIE_DO_LRU_DISCARD.

[PATCH OLK-6.6] tracefs: Use generic inode RCU for synchronizing freeing
by Long Li 09 Sep '24

09 Sep '24

From: Steven Rostedt <rostedt(a)goodmis.org> commit 0b6743bd60a56a701070b89fb80c327a44b7b3e2 upstream. With structure layout randomization enabled for 'struct inode' we need to avoid overlapping any of the RCU-used / initialized-only-once members, e.g. i_lru or i_sb_list to not corrupt related list traversals when making use of the rcu_head. For an unlucky structure layout of 'struct inode' we may end up with the following splat when running the ftrace selftests: [<...>] list_del corruption, ffff888103ee2cb0->next (tracefs_inode_cache+0x0/0x4e0 [slab object]) is NULL (prev is tracefs_inode_cache+0x78/0x4e0 [slab object]) [<...>] ------------[ cut here ]------------ [<...>] kernel BUG at lib/list_debug.c:54!

This will disturb concurrent list traversals as well as object reuse which assumes these list heads will keep their integrity. For reproduction, the following diff manually overlays 'i_lru' with 'rcu' as, otherwise, one would require some good portion of luck for gambling an unlucky RANDSTRUCT seed: --- a/include/linux/fs.h +++ b/include/linux/fs.h @@ -629,6 +629,7 @@ struct inode { umode_t i_mode; unsigned short i_opflags; kuid_t i_uid; + struct list_head i_lru; /* inode LRU list */ kgid_t i_gid; unsigned int i_flags; @@ -690,7 +691,6 @@ struct inode { u16 i_wb_frn_avg_time; u16 i_wb_frn_history; #endif - struct list_head i_lru; /* inode LRU list */ struct list_head i_sb_list; struct list_head i_wb_list; /* backing dev writeback list */ union { The tracefs inode does not need to supply its own RCU delayed destruction of its inode.

[PATCH openEuler-22.03-LTS-SP1] mptcp: pm: avoid possible UaF when selecting endp
by Liu Jian 09 Sep '24

09 Sep '24

From: "Matthieu Baerts (NGI0)" <matttbe(a)kernel.org> mainline inclusion from mainline-v6.11-rc5 commit 48e50dcbcbaaf713d82bf2da5c16aeced94ad07d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAOY17 CVE: CVE-2024-44974 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… ------------------------------------------------- select_local_address() and select_signal_address() both select an endpoint entry from the list inside an RCU protected section, but return a reference to it, to be read later on. If the entry is dereferenced after the RCU unlock, reading info could cause a Use-after-Free. A simple solution is to copy the required info while inside the RCU protected section to avoid any risk of UaF later. The address ID might need to be modified later to handle the ID0 case later, so a copy seems OK to deal with.

A simple solution is to copy the required info while inside the RCU protected section to avoid any risk of UaF later.

This may happen if the gadget doesn't properly set up the endpoint for the current speed, or the gadget descriptors are malformed and the descriptor for the speed/endpoint are not found. No current gadget driver is known to have this problem, but this may cause a hard-to-find bug during development of new gadgets.

[PATCH OLK-6.6] nfs: fix memory leak in error path of nfs4_do_reclaim
by Li Lingfeng 07 Sep '24

07 Sep '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAPAZ3 -------------------------------- Commit c77e22834ae9 ("NFSv4: Fix a potential sleep while atomic in nfs4_do_reclaim()") separate out the freeing of the state owners from nfs4_purge_state_owners() and finish it outside the rcu lock. However, the error path is omitted. As a result, the state owners in "freeme" will not be released. Fix it by adding freeing in the error path.

[PATCH OLK-5.10] nfs: fix memory leak in error path of nfs4_do_reclaim
by Li Lingfeng 07 Sep '24

07 Sep '24

hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAOYZS -------------------------------- Commit c77e22834ae9 ("NFSv4: Fix a potential sleep while atomic in nfs4_do_reclaim()") separate out the freeing of the state owners from nfs4_purge_state_owners() and finish it outside the rcu lock. However, the error path is omitted. As a result, the state owners in "freeme" will not be released. Fix it by adding freeing in the error path.
