| apw | oh how did you know that was what i just got handed | 10:22 |
| smb | Its the most likely thing happening :) | 10:22 |
| 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 | 10:23 |
| smb | Maybe at some point | 10:24 |
| smb | But before I woke, so I cannot tell when | 10:24 |
| apw | yeah | 10:25 |
| jjohansen1 | apw: are we using the saucy goldfish kernel at all? | 10:34 |
| === shuduo is now known as shuduo_afk | ||
| 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 | 10:39 |
| 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 | 10:40 |

| 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 | 11:09 |
| jjohansen1 | apw: I sent the patch for trusty, its the same for saucy if we want to apply it | 11:10 |

| 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? | 13:42 |
| rtg | http://en.wikipedia.org/wiki/Read-copy-update | 13:45 |
| 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. | 13:48 |
| * 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. | 13:53 |
| 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 | 13:54 |
| slab_allocator | ..mmm i suspect the number of people that actually can explain plain simply whata RCU is can be store in 1 bit | 13:56 |

| ppisati | bjf: oh thank you, you're so fluffy and tender :) | 17:31 |
| bjf | :-) | 17:33 |
| pkern | And the compilation of the kernel is reasonably broken as a result. Great. | 17:35 |
| * rtg -> EOD | 20:48 | |
| hallyn | stgraber: apw: the good news is the 3.13 trusty-unstable kernel lets me create/start containers as non-root beautifully | 20:58 |
| stgraber | hallyn: nice! do we have a PPA for that kernel? | 20:59 |
| 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 | 21:00 |
| stgraber | hallyn: is that only happening from a userns? | 21:05 |
| hallyn | yeah | 21:06 |
| hallyn | i end up getting: sendmsg: Bad file descriptor | 21:10 |
| hallyn | i have a bad feeling this is dbus-related | 21:12 |
| hallyn | it *is* also a rather weird kernel. things sseem to keep just hanging for a few seconds for no good reason | 21:14 |
| 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 | 21:15 |
| 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 :) | 22:10 |
