Hello Colin, or anyone else affected, Accepted irqbalance into vivid-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/irqbalance/1.0.6-3ubuntu1.1 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .

Suppose info is one address in heap, then it is valid, and the segfault
should be caused by invalid info->numa_node.

Finally I have figured out one simple way to reproduce the issue: 1) apply the attached debug patch to stress-ng 2) run the following script: sudo cat /proc/$(pidof irqbalance)/maps /home/ubuntu/git/stress-ng/stress-ng --sequential 0 --seq-start 80 --seq-end 84 -t 60 --syslog --metrics --times -v And the above command just runs the following 4 stresses in 4 minutes: stress-ng: info: [1067] dispatching hogs: 8 tsearch, 8 udp, 8 udp-flood, 8 urandom 3) the above may trigger the following faults from irqbalance with ~3/4 probability, and the faulted address is in heap, and PC points to code of libglib-2.0.so, so looks like a use-after-free in irqbalance or libglib? And no information shows it is related with kernel, also the four stresses are quite simple and shouldn't cause trouble to kernel. # irqbalance memory maps 0040-0040a000 r-xp 08:02 10496929 /usr/sbin/irqbalance 00419000-0041a000 r-xp 9000 08:02 10496929 /usr/sbin/irqbalance 0041a000-0041b000 rwxp a000 08:02 10496929 /usr/sbin/irqbalance 16294000-162b5000 rwxp 00:00 0 [heap] 162b5000-162ce000 rwxp 00:00 0 [heap] 7f8fbf9000-7f8fbfb000 rwxp 00:00 0 7f8fbfb000-7f8fc11000 r-xp 08:02 4722034 /lib/aarch64-linux-gnu/libpthread-2.21.so 7f8fc11000-7f8fc2 ---p 00016000 08:02 4722034 /lib/aarch64-linux-gnu/libpthread-2.21.so 7f8fc2-7f8fc21000 r-xp 00015000 08:02 4722034 /lib/aarch64-linux-gnu/libpthread-2.21.so 7f8fc21000-7f8fc22000 rwxp 00016000 08:02 4722034 /lib/aarch64-linux-gnu/libpthread-2.21.so 7f8fc22000-7f8fc26000 rwxp 00:00 0 7f8fc26000-7f8fc7f000 r-xp 08:02 4718668 /lib/aarch64-linux-gnu/libpcre.so.3.13.1 7f8fc7f000-7f8fc8f000 ---p 00059000 08:02 4718668 /lib/aarch64-linux-gnu/libpcre.so.3.13.1 7f8fc8f000-7f8fc9 r-xp 00059000 08:02 4718668 /lib/aarch64-linux-gnu/libpcre.so.3.13.1 7f8fc9-7f8fc91000 rwxp 0005a000 08:02 4718668 /lib/aarch64-linux-gnu/libpcre.so.3.13.1 7f8fc91000-7f8fdc1000 r-xp 08:02 4722027 /lib/aarch64-linux-gnu/libc-2.21.so 7f8fdc1000-7f8fdd ---p 0013 08:02 4722027 /lib/aarch64-linux-gnu/libc-2.21.so 7f8fdd-7f8fdd4000 r-xp 0012f000 08:02 4722027 /lib/aarch64-linux-gnu/libc-2.21.so 7f8fdd4000-7f8fdd6000 rwxp 00133000 08:02 4722027 /lib/aarch64-linux-gnu/libc-2.21.so 7f8fdd6000-7f8fdda000 rwxp 00:00 0 7f8fdda000-7f8fde3000 r-xp 08:02 10885206 /usr/lib/aarch64-linux-gnu/libnuma.so.1.0.0 7f8fde3000-7f8fdf2000 ---p 9000 08:02 10885206 /usr/lib/aarch64-linux-gnu/libnuma.so.1.0.0 7f8fdf2000-7f8fdf3000 r-xp 8000 08:02 10885206 /usr/lib/aarch64-linux-gnu/libnuma.so.1.0.0 7f8fdf3000-7f8fdf4000 rwxp 9000 08:02 10885206 /usr/lib/aarch64-linux-gnu/libnuma.so.1.0.0 7f8fdf4000-7f8fdf8000 rwxp 00:00 0 7f8fdf8000-7f8fe89000 r-xp 08:02 4722041 /lib/aarch64-linux-gnu/libm-2.21.so 7f8fe89000-7f8fe98000 ---p 00091000 08:02 4722041 /lib/aarch64-linux-gnu/libm-2.21.so 7f8fe98000-7f8fe99000 r-xp 0009 08:02 4722041 /lib/aarch64-linux-gnu/libm-2.21.so 7f8fe99000-7f8fe9a000 rwxp 00091000 08:02 4722041 /lib/aarch64-linux-gnu/libm-2.21.so 7f8fe9a000-7f8ff8c000 r-xp 08:02 4718610 /lib/aarch64-linux-gnu/libglib-2.0.so.0.4400.1 7f8ff8c000-7f8ff9c000 ---p 000f2000 08:02 4718610 /lib/aarch64-linux-gnu/libglib-2.0.so.0.4400.1 7f8ff9c000-7f8ff9d000 r-xp 000f2000 08:02 4718610 /lib/aarch64-linux-gnu/libglib-2.0.so.0.4400.1 7f8ff9d000-7f8ff9e000 rwxp 000f3000 08:02 4718610 /lib/aarch64-linux-gnu/libglib-2.0.

Otherwise we need pay close attention to the issue. And I always run 'stress-ng' as ubuntu user without sudo, that may be the reason why it is difficult for me to reproduce that. Even with the two new approaches, it is still not easy for me to reproduce that. I only see one time of translation fault by your first approach(./stress-ng --seq 0 ...) in 6 hours, and can't trigger that with your 2nd approach(by bash script). Folllows the log[1] I triggered, and I think it is very likely a userspace issue. From irqbalanc-dbgsym package, we can easily find 'PC is at 0x406078' is one address in text section, and it should be inside function of 'place_irq_in_node' because the exec file isn't built as relocation. One thing I still can't understand is that why the fault address is '0x0040' in the context. [1] [ 3616.92] Bits 55-60 of /proc/PID/pagemap entries are about to stop being page-shift some time soon.

Hi Colin, That looks one progress, but still takes time to reproduce that, and I will use your new approach to reproduce that. When you are doing that, could you dump the file of /proc/$(pidof irqbalance)/maps so that we can see where the faulted address are in the process's vm space? thanks, On Sat, Jul 4, 2015 at 4:10 AM, Colin Ian King <1469...@bugs.launchpad.net> wrote: > Running the following: > > #!/bin/bash > tests="affinity aio bigheap brk bsearch cache chdir chmod clock context cpu > crypt dentry dir dup epoll eventfd fstat fallocate fault fifo flock fork > futex get getrandom hdd hsearch inotify io itimer kcmp kill lease link lockf > longjmp lsearch malloc matrix memcpy memfd mincore mlock mmap mmapmany mremap > msg mq nice null open pipe poll procfs pthread qsort readahead rename rlimit > seek sem sem-sysv sendfile shm-sysv sigfd sigfpe sigq sigsegv sock splice > stack str switch symlink sysinfo sysfs tee timer timerfd tsearch udp > udp-flood urandom utime vecmath vfork vm vm-rw vm-splice wcs wait yield xattr > zero zombie" > > for t in $tests > do > echo $t > echo $t > /dev/kmsg > ./stress-ng --$t 0 -v -t 60 > done > > eventually tripped the translation fault in irqbalance.
