=== shuduo is now known as shuduo_afk
apwjjohansen1, that is a good question, i don't think we would be, i think trusty is probabally they one they are playing with10:39
apwjjohansen1, deciding whether it needs cves ?10:39
jjohansen1apw: not a CVE just a patch for bug#125370710:39
ogra_we dont ... as long as there is a trusty branch all is fine 10:39
jjohansen1ogra_: great10:39
jjohansen1apw: this bug still affects people who self compile a no-smp kernel, but I don't think thats worth pushing the patch into saucy for10:40

apwjjohansen1, 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 out11:09
jjohansen1apw: I sent the patch for trusty, its the same for saucy if we want to apply it11:10

slab_allocatorHi. I know it is a wide topic. But what is RCU read-copy-update mechanism?13:42
slab_allocatorI way to free CPU time?13:42
rtghttp://en.wikipedia.org/wiki/Read-copy-update13:45
slab_allocatorI was on that URL ... anyway a little bit obscufated for me...13:48
slab_allocatorI was looking for an abstract explanation.13:48
* henrix suspects the number of people that actually understand RCUs can be store in 2 bits13:53
pkernApparently editing a file below debian.raring was the right thing to do, despite the splitconfig.pl headers.13:53
TooLmaNNot 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 advance13:54
slab_allocator..mmm i suspect the number of people that actually can explain plain simply whata RCU is can be store in 1 bit13:56

pkernOne'd think that OS lessons at university would include RCU.14:11

ppisatibjf: oh thank you, you're so fluffy and tender :)17:31
bjf:-)17:33
pkernAnd the compilation of the kernel is reasonably broken as a result. Great.17:35
* rtg -> EOD20:48
hallynstgraber: apw: the good news is the 3.13 trusty-unstable kernel lets me create/start containers as non-root beautifully20:58
stgraberhallyn: nice! do we have a PPA for that kernel?20:59
stgraberI'll need it to test my config rework branch21:00
hallynstgraber: http://ppa.launchpad.net/canonical-kernel-team/ppa/ubuntu21:00
stgrabercool, will try that one in a bit21:00
hallynstgraber: the bad news is...  i can't seem to send SCM_CREDENTIALS 21:00
stgraberhallyn: is that only happening from a userns?21:05
hallynyeah21:06
hallyni end up getting: sendmsg: Bad file descriptor21:10
hallyni have a bad feeling this is dbus-related21:12
hallynit *is* also a rather weird kernel.  things sseem to keep just hanging for a few seconds for no good reason21:14
hallynok yeah, just doing pidns|mountns works fine, just the userns messes it up21:15
hallynsee noreason for it in net/core/scm.c21:15
hallynstgraber: 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 :)22:10
