Subject: Could we get 4.4.285-cip release? ([ANNOUNCE] 4.4.285-rt226 (fwd))

Hi!

4.4.285-rt226 is out it would be good to make it into -cip-rt
release.

Would it be possible to create 4.4.285-cip release to make it
easier?

Thanks and best regards,
Pavel

Subject: [ANNOUNCE] 4.4.285-rt226

Hello RT-list!

I'm pleased to announce the 4.4.285-rt226 stable release.

There are some futex changes in the RT code which were necessary
because of the fuxex backports in v4.4.280. It took me a while to
figure the merge conflicts and what needs to be changed in the
futex/rtmutex patches. The v4.4 version of "Add the rtmutex rework"
path is updated. The the locking rules changed, see the fixup patch
for hb->lock and mutex->wait_lock.

Unfortunatly, I am not able to upload the patches to the usual places
because I had to create a new gpg subkey as my old one expired. And
now kup tells me my signature is invalid. I created a ed25519 signing
key instead of a rsa one. Maybe this is what kup upsets. No idea and
the security tools are helpful as always... NOT.

As I didn't want to delay the release even more I only pushed the
changes to the git tree.

You can get this release via the git tree at:

git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git

branch: v4.4-rt
Head SHA1: b045f6da3d00b1423045781f9ec069827ea6a42a

Enjoy!
Daniel

Subject: [cip-dev] New CVE entry this week

Hi !

It's this week's CVE report.

This week reported one new CVE.

* New CVEs

CVE-2021-20317: lib/timerqueue: Rely on rbtree semantics for next timer

This bug has been fixed in 5.4-rc1 so that before 5.4 kernels are
affected. For 4.19, patch can be applied without any modification. For
4.4, it needs to modify patch to apply it.
According to the description in
cve.mitre.org(https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-20317),
it describes "This flaw allows a local attacker with special user
privileges to cause a denial of service" so I think this vulnerability
severity may be low.

CVSS v3 score is not provided.
