Hi Folks, libvirt currently spams the logs with error : virCgroupGetMemoryStat:2490 : internal error: Cannot parse 'memory.stat' cgroup file whenever someone does ps in a container. This is because the parser for memory/stat is incorrect: the `line' variable is never updated, so each time through the loop, the same start-of-line is compared for the token; and as all spaces are eventually replaced with NUL the error exit is taken instead of ending the loop properly. Here is a strawman patch to fix the problem. Please note, I'm not subscribed to this list; I reported the bug as https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=913023 and was asked to send the patch upstream. src/util/vircgroup.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) --- libvirt.orig/src/util/vircgroup.c +++ libvirt/src/util/vircgroup.c @@ -2477,7 +2477,7 @@ virCgroupGetMemoryStat(virCgroupPtr grou line = stat; - while (line) { + while (*line) { char *newLine = strchr(line, '\n'); char *valueStr = strchr(line, ' '); unsigned long long value; @@ -2507,6 +2507,11 @@ virCgroupGetMemoryStat(virCgroupPtr grou inactiveFileVal = value >> 10; else if (STREQ(line, "unevictable")) unevictableVal = value >> 10; + + if (newLine) + line = newLine + 1; + else + break; } *cache = cacheVal; -- Dr Peter Chubb Tel: +61 2 9490 5852 http://ts.data61.csiro.au/ Trustworthy Systems Group Data61 (formerly NICTA)
