RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Red Hat Product Errata RHBA-2016:2418 0 normal SHIPPED_LIVE audit bug fix and enhancement update 2016-11-03 13:58:32 UTC

Description Dalibor Pospíšil 2015-10-14 13:24:42 UTC 
Description of problem:
audit2allow -b is trying to get boot time (I do not know from where) and it fail to decode it if LANG is set to some of the locales.

Following are the problematic ones, particularly on RHEL7.2:
ar_AE.iso88596, ar_AE.utf8, ar_BH, ar_BH.iso88596, ar_BH.utf8, ar_DZ, ar_DZ.iso88596, ar_DZ.utf8, ar_EG, ar_EG.iso88596, ar_EG.utf8, ar_IQ, ar_IQ.iso88596, ar_IQ.utf8, ar_JO, ar_JO.iso88596, ar_JO.utf8, ar_KW, ar_KW.iso88596, ar_KW.utf8, ar_LB, ar_LB.iso88596, ar_LB.utf8, ar_LY, ar_LY.iso88596, ar_LY.utf8, ar_MA, ar_MA.iso88596, ar_MA.utf8, ar_OM, ar_OM.iso88596, ar_OM.utf8, ar_QA, ar_QA.iso88596, ar_QA.utf8, ar_SD, ar_SD.iso88596, ar_SD.utf8, ar_SY, ar_SY.iso88596, ar_SY.utf8, ar_TN, ar_TN.iso88596, ar_TN.utf8, ar_YE, ar_YE.iso88596, ar_YE.utf8, as_IN, as_IN.utf8, bo_CN, bo_CN.utf8, bo_IN, bo_IN.utf8, bokmal, bokm, dz_BT, dz_BT.utf8, fa_IR, fa_IR.utf8, ja_JP, ja_JP.eucjp, ja_JP.ujis, ja_JP.utf8, japanese, japanese.euc, ko_KR, ko_KR.euckr, ko_KR.utf8, korean, korean.euc, nb_NO, nb_NO.iso88591, nb_NO.utf8, nn_NO, nn_NO.iso88591, nn_NO.utf8, no_NO, norwegian, nynorsk, or_IN, or_IN.utf8, sq_AL, sq_AL.iso88591, sq_AL.utf8, sq_MK, sq_MK.utf8, te_IN, te_IN.utf8, yue_HK, yue_HK.utf8, zh_CN, zh_CN.gb18030, zh_CN.gb2312, zh_CN.gbk, zh_CN.utf8, zh_HK, zh_HK.big5hkscs, zh_HK.utf8, zh_SG, zh_SG.gb2312, zh_SG.gbk, zh_SG.utf8, zh_TW, zh_TW.big5, zh_TW.euctw, zh_TW.utf8

Comment 1 Petr Lautrbach 2015-10-14 14:28:38 UTC 
see https://bugzilla.redhat.com/show_bug.cgi?id=1197235
Comment 2 Steve Grubb 2015-10-14 16:29:43 UTC 
I tested this on F22, and it doesn't seem to have this problem. But then again I have logs that are recorded in en_US.UTF-8. 

What version of audit is being used?
Can you include 2 or 3 lines out logs generated from this command:
# grep audit /var/log/messages | grep 1400

Thanks
Comment 3 Dalibor Pospíšil 2015-11-10 09:45:41 UTC 
After reboot I get:
# LANG=ar_AE audit2allow -b
Invalid start time (CET 10:36:03 ). Hour, Minute, and Second are required.

# grep audit /var/log/messages
Nov 10 07:45:01 sopos-rhel7-brq auditd[562]: Audit daemon rotating log files
Comment 4 Steve Grubb 2015-11-10 15:35:25 UTC 
What I was asking for is samples of the logs that are causing the problems. I specifically wanted the ones with 1400 because those are AVC's. You also didn't answer the question about which version of audit you are using.

When I use the one and only one log line you pasted, I cannot reproduce the problem.

# echo "Nov 10 07:45:01 sopos-rhel7-brq auditd[562]: Audit daemon rotating log files" | LANG=ar_AE audit2allow -b
<no matches>

If I can't reproduce the error, I can't fix it. Thanks.
Comment 5 Dalibor Pospíšil 2015-11-11 16:59:56 UTC 
I use audit-2.4.1-5.el7.

Actually I do not know where the boot timestamp comes form so I cannot check the format.
Comment 6 Steve Grubb 2016-01-13 20:43:37 UTC 
Going back to comment #2, I need some log samples to look at. Can you run the following for me:

# grep 'type=AVC' /var/log/audit/audit.log | head -n 3
Comment 7 Steve Grubb 2016-01-13 23:53:11 UTC 
Looking through the sepolgen code I find this:

    fd=open("/proc/uptime", "r")
    off=float(fd.read().split()[0])
    fd.close
    s = time.localtime(time.time() - off)
    bootdate = time.strftime("%x", s)
    boottime = time.strftime("%X", s)
    output = subprocess.Popen(["/sbin/ausearch", "-m", "AVC,USER_AVC,MAC_POLICY_LOAD,DAEMON_START,SELINUX_ERR", "-ts", bootdate, boottime],

Based on that, I'm inclined to believe this bz is a duplicate of Bug #1286633.
Comment 11 Steve Grubb 2016-04-29 17:30:56 UTC 
audit-2.5.2-1.el7 has been built to address this issue
