| tseliot | apw: what is the proper way to request a config change in the kernel? I need DRM_AMD_POWERPLAY=y for my backport | 15:38 |
|---|---|---|
| apw | tseliot, at this stage, a bug with the justification would be good, and then a patch as normal | 15:43 |
| apw | or file the bug, and just tell me the number | 15:43 |
| apw | tseliot, or are you asking how to apply a change in a big pull request ? | 15:43 |
| tseliot | apw: that could probably fit the same bug report I filed for my backport (which affects the same code) | 15:44 |
| tseliot | apw: I was thinking it would be worth doing it myself as part of the pull request | 15:44 |
| tseliot | since, you know, backporting code just to keep it disabled is probably a little useless :D | 15:45 |
| tseliot | the thing is, I don't recall doing that before | 15:45 |
| tseliot | (a config change) | 15:46 |

| leitao | rtg, hello. It seems that there is an issue with kernel 3.19 on the fixes for 1481357. | 18:22 |
| rtg | leitao, yeah, I see verification-failed-vivid | 18:23 |
| leitao | good. I want just to make sure that it does not fly under the radar. Thank you! | 18:23 |
| rtg | leitao, I'll look at it a bit later this afternoon. gotta wrap up some other stuff first. | 18:25 |
| leitao | rtg, no worries. As I said, just to make sure that you guys saw the problem. | 18:26 |
| tych0 | hi folks. i'm on the xenial kernel, 4.4.0-8-generic | 18:52 |
| hallyn | sforshee: apw: hey, tych0 is finding apparmorfs sometimes not loaded | 18:52 |
| tych0 | and i'm missing my /sys/kernel/security/apparmor is missing | 18:52 |
| hallyn | but sometimes loaded (and for me it is loaded) | 18:52 |
| hallyn | tych0: anything in journalctl? | 18:52 |
| tych0 | yeah, for me it is loaded too on other vms but this one | 18:53 |
| tych0 | nothing jumps out at me, but, http://paste.ubuntu.com/15245948/ | 18:53 |
| tyhicks | Feb 29 11:40:56 criu2 kernel: AppArmor: AppArmor disabled by boot time parameter | 18:54 |
| tyhicks | Feb 29 11:40:56 criu2 kernel: Command line: BOOT_IMAGE=/boot/vmlinuz-4.4.0-8-generic ... selinux=1 security=selinux ... | 18:55 |
| hallyn | tsk tsk | 18:55 |
| tych0 | oh | 18:55 |
| tych0 | how did that get there :) | 18:56 |
| hallyn | gremlins? | 18:56 |
| tych0 | or an extremely elaborate troll | 18:57 |
| tyhicks | I vaguely remember seeing a xenial bug go by for a package that was depending on selinux-policy-default | 18:57 |
| tych0 | i wonder how i turn it off | 18:58 |
| tych0 | somehow i do have that package installed, let's see what happens if i uninstall it | 18:58 |
| tyhicks | tych0: do you have the "selinux" binary package installed? | 18:59 |
| tych0 | rc selinux 1:0.11 all Security-Enhanced Linux runtime support | 19:00 |
| tych0 | but that might be because i just removed some stuff | 19:00 |
| tyhicks | tych0: ok, do you have the "apparmor" package installed? | 19:01 |
| tych0 | tyhicks: yes, i have that one | 19:01 |
| tyhicks | tych0: hmm... I thought that if you had it installed, it would set the right kernel boot params but it has been a while since I've tried switching between apparmor and selinux | 19:02 |
| tych0 | wwell, let me try to --reinstall | 19:03 |
| tyhicks | that may work | 19:03 |
| tych0 | hm, even that didn't do it | 19:04 |
| tych0 | well never mind, maybe i'll just blow this vm away and start over :) | 19:07 |
| tyhicks | tych0: the selinux packaging simply modifies /etc/default/grub to add security=selinux selinux=1 | 19:07 |
| tych0 | ah, ok | 19:08 |
| tyhicks | tych0: you should be able to remove those two params and run update-grub2 to return to using apparmor since our kernels are configured to use apparmor by default | 19:08 |
| tych0 | oh | 19:08 |
| tych0 | update-grub2 vs. update-grub :) | 19:08 |
| tyhicks | either one | 19:08 |
| tyhicks | I think they're the same | 19:08 |
| tyhicks | yeah, update-grub2 is a symlink to update-grub | 19:09 |
| tych0 | ok, cool | 19:09 |
| tych0 | tyhicks: \o/ thanks! | 19:13 |
| tyhicks | tych0: glad that it worked :) | 19:13 |

| rharper | on Xenial, I've a USB flash drive that shows up when directly connected to x1 carbon gen1; but when plugged in via USB3 hub does not; other usb devices on hub work (keyboard, nic, mouse) but not mass storage devices; worked fine in 15.10; thoughts? lsusb does not even list the device when plugged in | 21:06 |
| * hallyn at that point in writing a new kernel patch where you wonder 'do i type make for the first time and see where it breaks, or reread the patch to look for obvious errors?' | 23:49 | |
