Linux 3.14-rc8

Linux 3.14-rc8

[Linus Torvalds]

I delayed things a day from my normal schedule, hoping I'd feel more
comfortable doing a 3.14 release, but that was not to be. So here's an
rc8, and I expect to do the final 3.14 release next weekend.

There wasn't that much scary stuff going on, but there's a few vfs
fixes still pending, and we did end up having some interesting core
fixes last week too (not new regressions, but newly detected by
Trinity. Kudos to Hugh Dickins for figuring them out and fixing the
causes). There's also some networking fixes and random noise (mainly
MIPS).  So I really wanted another week before release after all.

FWIW, since Hugh's heroic work nailing those bugs, I've managed to run
trinity for days since without problems[1]. As we discussed today at the VM summit,
Sasha has found a bunch of things in -next that may be a problem in .14 too, 
(and in fact I've hit one of those BUGONs once), but on the whole it's looking
a lot better.

[1] Actually, I've since crashed my test box for stupid reasons now that
    I'm 3000 miles away from it until the end of the week, but I have a way better
    opinion of rc8 than I did of rc7.

Re: Linux 3.14-rc8 (LXC broken)

[Andre Tomt]

*testing hat on*

PAM within namespaces (say, LXC) does not work anymore with 3.14-rc8,
making login, ssh etc fail in containers unless you boot with audit=0.

This is due to a change in return value to user space; and is
appearantly a known issue as evident in this earlier post from february:
https://www.redhat.com/archives/linux-audit/2014-February/msg00087.html

Judging from the post it seems they want to ship 3.14 with this IMO
quite serious regression? What is the namespace/container folks take on
this?

Without looking too deeply, it seems to me that patch has no
benefit on its own, and should simply be stashed until the next
set of patches are ready.

Fair question.

Pam only worked in non-initial pid (or user) namespace if it was also in
the non-initial network namespace.  We added support for the network
namespace in 3.14.  So now PAM in the non-initial network namespace
functions the same as it would in the inital network namespace.  aka, it
fails.  This is actually what the audit userspace people think is the
right thing to happen.  You configured PAM to fail if it couldn't do the
right audit things, and it's failing.  Needing audit=0 is not new.

BUT given we broke (already broken [remember you configured PAM to fail
if audit didn't go well and it let you log in anyway?  aka broken?])
functionality adding network namespace support I'll send a request to
Linus tomorrow to rip out our network namespace support and I'll re-add
in 3.15 when we add pid (and partial user) namespace support.
