Descripción

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