[Bug 1385641] Re: urfkilld use 100% cpu after resume
On Linux Mint have just encountered issue and confirmed is urfkill on 27/05/2018. Fan going nuts, cpmputer at a crawl, 'top' showed 100% CPU from urfkilld. I suspected something was off for quite a while. I believe the this softwarealso led to a number of crashes and loss of unsaved data. Whatever else happens, no software should be designed to hog resources like that. Productivity is the most important thing so why on earth is Linux still dependent on such poorly coded software? This is exactly the type of thing that makes people run far away from Linux. As urfkill is clearly not well built with the same issue since 2014, excuse my language but what did we lose if we uninstall this crap? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1385641 Title: urfkilld use 100% cpu after resume To manage notifications about this bug go to: https://bugs.launchpad.net/urfkill/+bug/1385641/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1385641] Re: urfkilld use 100% cpu after resume
In urf-input.c, there's a line
if (condition G_IO_IN) {
which needs to be
if (condition G_IO_IN !(G_IO_ERR | G_IO_HUP)) {
This is because the actual condition passed to the function after
suspend/resume and consequent new inode # for /dev/input/event4 is
(gdb) p condition
$2 = (G_IO_IN | G_IO_ERR | G_IO_HUP)
i.e. we're getting G_IO_IN and error conditions signalled at the same
time. The simple fix above resolves the 100% CPU issue for me and
urfkill still reacts correctly to messages like in

[Bug 1385641] Re: urfkilld use 100% cpu after resume
The workaround works for me (with Dell XPS Developer Edition). Regarding what's actually happening, it looks like after suspend/resume the input device used by urfkill (in my case, /dev/input/event4) comes back with a different inode number, so that the file descriptor held by urfkill is invalid, as seen in Alex' /proc/pid/fd listing above as well. I assume the device driver deletes the file on suspend and recreates it on resume. Restarting urfkill makes it open the file during initialization, and consequently the file descriptor is valid and the issue does not occiur. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1385641 Title: urfkilld use 100% cpu after resume To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/urfkill/+bug/1385641/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
