Subject: restorecond going crazy on 2.6.31.4 - inotify regression?
Date: Thu, 15 Oct 2009 18:03:04 -0600 [thread overview]
Message-ID: <4AD7B838.8030305@gmail.com> (raw)
I just upgraded to 2.6.31.4 on a CentOS 5.3 x86_64 machine, and noticed
the SELinux restorecond daemon using 100% CPU. Previously it was running
2.6.30.7 which didn't have this problem. It looks like it's triggered by
either opening or closing a gnome-terminal. strace on restorecond shows
the following repeating continuously
inotify_add_watch(3, "/var/run/utmp", IN_MODIFY|IN_MOVED_FROM) = 9
read(3, "\t\0\0\0\0\200\0\0\0\0\0\0\0\0\0\0", 32768) = 16
write(1, "wd=9 mask=32768 cookie=0 len=0\n", 31wd=9 mask=32768 cookie=0
len=0
) = 31
open("/var/run/utmp", O_RDONLY) = 4
fstat(4, {st_mode=S_IFREG|0664, st_size=5760, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0)
= 0x7fe0d938c000
read(4,
"\10\0\0\0\177\2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 4096)
= 4096
read(4,
"\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"...,
4096) = 1664
read(4, "", 4096) = 0
close(4) = 0
munmap(0x7fe0d938c000, 4096) = 0
inotify_rm_watch(3, 9) = 0
inotify_add_watch(3, "/var/run/utmp", IN_MODIFY|IN_MOVED_FROM) = 9
It looks like it's getting continuous notifications that /var/run/utmp
has changed, which seems a bit odd. I know there were some inotify
issues in the 2.6.31 series, is there something still amiss?
