- xfs: avoid dereferencing log items after push callbacks
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
xfs: avoid dereferencing log items after push callbacks
After xfsaildpushitem() calls ioppush(), the log item may have been freed if the AIL lock was dropped during the push. Background inode reclaim or the dquot shrinker can free the log item while the AIL lock is not held, and the tracepoints in the switch statement dereference the log item after ioppush() returns.
Fix this by capturing the log item type, flags, and LSN before calling xfsaildpushitem(), and introducing a new xfsailpush_class trace event class that takes these pre-captured values and the ailp pointer instead of the log item pointer.
