From: Eric Biggers <ebiggers(a)google.com>
When writing a page from an encrypted file that is using
filesystem-layer encryption (not inline encryption), f2fs encrypts the
pagecache page into a bounce page, then writes the bounce page.
It also passes the bounce page to wbc_account_cgroup_owner(). That's
incorrect, because the bounce page is a newly allocated temporary page
that doesn't have the memory cgroup of the original pagecache page.
This makes wbc_account_cgroup_owner() not account the I/O to the owner
of the pagecache page as it should.
Fix this by always passing the pagecache page to
wbc_account_cgroup_owner().

This series backports patches in order to resolve the issue discussed here:
https://lore.kernel.org/selinux/389334fe-6e12-96b2-6ce9-9f0e8fcb85bf@huawei…
This required backporting the non-blocking LSM policy update mechanism
prerequisite patches.
Paul Moore has reviewed the non-blocking LSM policy update backport,
saying the SELinux part look good. The patchset was also reviewed by Mimi
Zohar
and everything looks ok.
I've tested the patches against the said issue and can confirm that the
issue is fixed. I've also run the LTP testcases on the fixed IMA and all
tests are passed.
This is a re-send of the original patchset as the original patchset
might have a faulty cover letter. The original patchset could be found
here:
https://patchwork.kernel.org/project/linux-integrity/list/?series=709367
GUO Zihua (1):
ima: Handle -ESTALE returned by ima_filter_rule_match()
Janne Karhunen (2):
LSM: switch to blocking policy update notifiers
ima: use the lsm policy update notifier

Hello,

failure, Note this, soonest you receive this email revert to me before
I deliver the message it's importunate, pressing, crucial. Await your
response.
Best regards
Dr. Moustapha Sanon
According to schematics it is PF15 and not PF14 (MIC_SW_EN).
Seems as if it was hidden and not noticed during testing since
there is no sound DT node.
