Subject: linux-next: manual merge of the apparmor tree with the security tree

Hi all,

Today's linux-next merge of the apparmor tree got a conflict in:

security/apparmor/lsm.c

between commit:

3c3bda37ca1d ("AppArmor: Add selfattr hooks")

from the security tree and commits:

bd7bd201ca46 ("apparmor: combine common_audit_data and apparmor_audit_data")
d20f5a1a6e79 ("apparmor: rename audit_data->label to audit_data->subj_label")

from the apparmor tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Thanks Stephen.

John, can you take a look and make sure this is correct (it looks okay to me)?

Paul just to double check, to make sure we get ordering on this right
3c3bda37ca1d ("AppArmor: Add selfattr hooks")

is part of the Three basic syscalls series, the plan is still to have that
series bake in next for a full cycle?

Regardless, I will wait until security-ext gets merged to send my pull
request, and handle the conflict if its present.

Yes, that's still the plan. Once v6.7-rc1 is out I'll rebase the LSM
syscall patches and I expect the vast majority of these conflicts to
disappear, although I'm sure we'll pick up some new ones with the rest
of the v6.7-rcX cycle :)

These patches should not be in linux-next until after v6.7-rc1.

What if we wanted additional testing beyond the typical? Do you not
support that?

This is now a conflict between the security tree and Linus' tree.

No, I try hard not to. It just complicates things when I and others
have to cope with conflicts and build problems caused by
patches/features destined for next+1 while trying to stabilise the
current/next release.

Sometimes it happens that a feature slips after being added to -next,
but please don't do it deliberately.

The LSM, SELinux, and audit dev-staging branches will no longer flow
into the next branches, and I've reset the current lsm/next branch so
this should not be an issue the next time you pull.

Thanks for that. It can all come back after the merge window, of course.
