Description Karel Srot 2013-06-07 05:23:38 EDT
Description of problem:

rlRun contain

                [ -n "$LOG_FILE" ] || LOG_FILE=$( mktemp --tmpdir=$__INTERNAL_PERSISTENT_TMP )
                LOG_FILE=$( mktemp --tmpdir=$__INTERNAL_PERSISTENT_TMP )
which sets DO_LOG=true and fails to set LOG_FILE because on RHEL-5 mktemp doesn't support --tmpdir option.

later on LOG_FILE is set to /dev/null via

[ -n "$LOG_FILE" ] || LOG_FILE="/dev/null"

at the end of the function there is:

    elif $DO_LOG; then
        rm $LOG_FILE

which removes /dev/null.

Beside fixing the --tmpdir issue I think either of following options would do the job.

  set [ -n "$LOG_FILE" ] || LOG_FILE="/dev/null" && DO_LOG=false
    elif $DO_LOG && [ "$LOG_FILE" != /dev/null ]; then
        rm $LOG_FILE

I am using

Moving this to internal product, as I will fix this in RHEL packages only.
Comment 4 Petr Muller 2013-06-07 08:39:57 EDT
Or not.
Comment 5 Petr Muller 2013-06-07 08:51:55 EDT
Okay: when LOG_FILE fails to be created (and /dev/null is used instead), it's probably a BeakerLib problem. In this case the advanced switches are turned off, and therefore the LOG_FILE is not erased.

Comment 6 Petr Muller 2013-06-07 08:53:48 EDT
And this part is clearly not urgent (the --tmpdir part probably is, but that's different story)

If /dev/null is deleted it is recreated as a regular file by any script running >/dev/null. Such a file has wrong selinux context and various services (and therefore also a lot of tests) do not work properly because they cannot access /dev/null (snmpd as an example).
Comment 8 Petr Muller 2013-06-07 09:25:52 EDT
Yep, but /dev/null should be never used for logging in the first place. When the tmp file is created, then /dev/null is not used and therefore not removed.

This remains simply a robustification and better handling of weird error states, but with the wrong mktemp call, we are *causing* weird error state.

But, it's just paper pushing. I'll try to push both fixes in one batch, and will try to do it soon.
