[00:27] <hallyn> wait, what?  I hadn't heard of 'trusty unstable' branch before - is that built in a ppa somewhere?
[00:56] <infinity> hallyn: https://launchpad.net/~canonical-kernel-team/+archive/ppa/+packages
[01:19] <hallyn> infinity: ah, thanks.  (i was looking for something with unstable in the name :)
[06:41] <infinity> zequence: It's that time of month again.
[09:04]  * smb yawns (before apw does)
[10:19]  * cking offers apw a coffee
[10:19] <smb> A big one
[10:22] <apw> oh how did you know that was what i just got handed
[10:22] <smb> Its the most likely thing happening :)
[10:23] <apw> heh, that i cannot deny at all
[10:23] <apw> so we have had another netsplit i assume, from my random change to my nick
[10:24] <smb> Maybe at some point
[10:24] <smb> But before I woke, so I cannot tell when
[10:25] <apw> yeah
[10:34] <jjohansen1> apw: are we using the saucy goldfish kernel at all?
[10:39] <apw> jjohansen1, that is a good question, i don't think we would be, i think trusty is probabally they one they are playing with
[10:39] <apw> jjohansen1, deciding whether it needs cves ?
[10:39] <jjohansen1> apw: not a CVE just a patch for bug#1253707
[10:39] <ogra_> we dont ... as long as there is a trusty branch all is fine 
[10:39] <jjohansen1> ogra_: great
[10:40] <jjohansen1> apw: this bug still affects people who self compile a no-smp kernel, but I don't think thats worth pushing the patch into saucy for
[11:08] <apw> bug #125707
[11:08] <ubot2> Launchpad bug 125707 in Jokosher "Track playback while recording only works from the begining of the track" [Undecided,New] https://launchpad.net/bugs/125707
[11:08] <apw> bug #1253707
[11:08] <ubot2> Launchpad bug 1253707 in linux-goldfish (Ubuntu Trusty) "apparmor backtraces for goldfish kernel" [Undecided,Confirmed] https://launchpad.net/bugs/1253707
[11:09] <apw> jjohansen1, yeah i think we may not yet have trusty branches but we should have, and that one would be something we are going to be using, so i say send it up and that will make us sort that out
[11:10] <jjohansen1> apw: I sent the patch for trusty, its the same for saucy if we want to apply it
[11:15] <apw> jjohansen1, ok you are ahead of me :)
[13:42] <slab_allocator> Hi. I know it is a wide topic. But what is RCU read-copy-update mechanism?
[13:42] <slab_allocator> I way to free CPU time?
[13:45] <rtg> http://en.wikipedia.org/wiki/Read-copy-update
[13:48] <slab_allocator> I was on that URL ... anyway a little bit obscufated for me...
[13:48] <slab_allocator> I was looking for an abstract explanation.
[13:53]  * henrix suspects the number of people that actually understand RCUs can be store in 2 bits
[13:53] <pkern> Apparently editing a file below debian.raring was the right thing to do, despite the splitconfig.pl headers.
[13:54] <TooLmaN> Not directly a kernel question, but I'm trying to put Ubuntu Core on an old 1GB Wyse thin client.  I have the partitions, rootfs, and kernel files all installed and in place.  My problem is with syslinux.  I have a basic config file pointing out the kernel and initrd files as well as the root partition, but on boot I get boot error.  What else should I check?  Thanks in advance
[13:56] <slab_allocator> ..mmm i suspect the number of people that actually can explain plain simply whata RCU is can be store in 1 bit
[14:11] <pkern> One'd think that OS lessons at university would include RCU.
[15:05] <bjf> ppisati, it's crank turing week here at the ranch
[15:06] <ppisati> bjf: oh right
[17:29] <ppisati> bjf: everything should be done
[17:30] <bjf> ppisati, your the man!
[17:31] <ppisati> bjf: oh thank you, you're so fluffy and tender :)
[17:33] <bjf> :-)
[17:35] <pkern> And the compilation of the kernel is reasonably broken as a result. Great.
[20:48]  * rtg -> EOD
[20:58] <hallyn> stgraber: apw: the good news is the 3.13 trusty-unstable kernel lets me create/start containers as non-root beautifully
[20:59] <stgraber> hallyn: nice! do we have a PPA for that kernel?
[21:00] <stgraber> I'll need it to test my config rework branch
[21:00] <hallyn> stgraber: http://ppa.launchpad.net/canonical-kernel-team/ppa/ubuntu
[21:00] <stgraber> cool, will try that one in a bit
[21:00] <hallyn> stgraber: the bad news is...  i can't seem to send SCM_CREDENTIALS 
[21:05] <stgraber> hallyn: is that only happening from a userns?
[21:06] <hallyn> yeah
[21:10] <hallyn> i end up getting: sendmsg: Bad file descriptor
[21:12] <hallyn> i have a bad feeling this is dbus-related
[21:14] <hallyn> it *is* also a rather weird kernel.  things sseem to keep just hanging for a few seconds for no good reason
[21:15] <hallyn> ok yeah, just doing pidns|mountns works fine, just the userns messes it up
[21:15] <hallyn> see noreason for it in net/core/scm.c
[22:10] <hallyn> stgraber: aha.  it's -EBADF bc for some reason in that case the socket has gotten closed (by dbus) before i got to sendmsg.  may still be my fault :)
