Description Mark Salyzyn 2013-01-04 15:13:35 UTC
Description of problem:
As noted in https://code.google.com/p/conman/issues/detail?id=16
conman fails to start up on some timezones.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. /usr/share/zoneinfo/Etc/GMT-1 used for /etc/localtime
2. startup of command fails

NB: informed customer to switch to Europe/Vienna as workaround.
Actual results:
conman startup notices in log:
NOTICE: Starting ConMan daemon 0.2.5 (pid 86513)
INFO: Open file limit set to 1024
ERROR: strftime() failed

Expected results:
expected conman deamon to function

Additional info:

The problem is create_long_time_string(time_t t) has const int len set to 25, when it should be 29 (or higher) to deal with all known current timezone codes. Recommend it be set to 32 to provide an engineering margin.

in util_str.c:
char * create_long_time_string(time_t t)
    char *p;
    struct tm tm;
    const int len = 25;                 /* YYYY-MM-DD HH:MM:SS ZONE + NUL */

    if (!(p = malloc(len))) {
    get_localtime(&t, &tm);

    if (strftime(p, len, "%Y-%m-%d %H:%M:%S %Z", &tm) == 0) {
        log_err(0, "strftime() failed");

Comment 2 Mark Salyzyn 2013-01-07 16:01:28 UTC
NB: https://code.google.com/p/conman/issues/detail?id=16 the fix accepted by the author was to change const int len = 25 to 32.
