Merge tag 'ipe-pr-20260925' of git://git.kernel.org/pub/scm/linux/kernel/git/wufan/ipegrafted
Pull IPE fixes from Fan Wu:
"Two fixes for use-after-free issues found by recent LLM-assisted code
analysis.
- move successful policy load auditing under the new policy
directory's inode lock, preventing a concurrent policy deletion
from freeing the policy while it is still being audited
- protect the dm-verity root hash with RCU, preventing policy
evaluation from racing with root hash replacement during preresume"

If a program wishes to find different things in + the tree, please use the /sys/class structure and rely + on the symlinks there to point to the proper location + within the /sys/devices tree of the individual devices. + Or rely on the uevent messages to notify programs of + devices being added and removed from this tree to find + the location of those devices. + + Note that sometimes not all devices along the directory + chain will have emitted uevent messages, so userspace + programs must be able to handle such occurrences. + +Users: + udev <linux-hotplug-devel@lists.sourceforge.net> |
