Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
xfs: stop reclaim before pushing AIL during unmount<br />
<br />
The unmount sequence in xfs_unmount_flush_inodes() pushed the AIL while<br />
background reclaim and inodegc are still running. This is broken<br />
independently of any use-after-free issues - background reclaim and<br />
inodegc should not be running while the AIL is being pushed during<br />
unmount, as inodegc can dirty and insert inodes into the AIL during the<br />
flush, and background reclaim can race to abort and free dirty inodes.<br />
<br />
Reorder xfs_unmount_flush_inodes() to stop inodegc and cancel background<br />
reclaim before pushing the AIL. Stop inodegc before cancelling<br />
m_reclaim_work because the inodegc worker can re-queue m_reclaim_work<br />
via xfs_inodegc_set_reclaimable.
