To reproduce the conflict and resubmit, you may use the following commands:
git fetch https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/ linux-6.5.y git checkout FETCH_HEAD git cherry-pick -x 793838138c157d4c49f4fb744b170747e3dabf58 # <resolve conflicts, build, test, etc.> git commit -s git send-email --to 'stable@vger.kernel.org' --in-reply-to '2023112456-linked-nape-bf19@gregkh' --subject-prefix 'PATCH 6.5.y' HEAD^..
Possible dependencies:
793838138c15 ("prctl: Disable prctl(PR_SET_MDWE) on parisc") 24e41bf8a6b4 ("mm: add a NO_INHERIT flag to the PR_SET_MDWE prctl") 0da668333fb0 ("mm: make PR_MDWE_REFUSE_EXEC_GAIN an unsigned long")
Greg, I think the most clean solution is that you pull in this patch:
commit 24e41bf8a6b424c76c5902fb999e9eca61bdf83d Author: Florent Revest revest@chromium.org Date: Mon Aug 28 17:08:57 2023 +0200 mm: add a NO_INHERIT flag to the PR_SET_MDWE prctl
as well into 6.5-stable and 6.6-stable prior to applying my patch.
Florent, Kees and Catalin, do you see any issues if this patch ("mm: add a NO_INHERIT flag to the PR_SET_MDWE prctl") is backported to 6.5 and 6.6 too? If yes, I'm happy to just send the trivial backport of my patch below...
Given that we need an explicit ack for adding mm: patches to the stable trees, I'll wait for that to happen here before adding it.
thanks,
