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 RHEA-2016:2401 0 normal SHIPPED_LIVE rsyslog bug fix and enhancement update 2016-11-03 13:55:50 UTC

Description Chris Adams 2014-09-24 20:19:28 UTC 
With the RHEL 7 version of rsyslog, you include the omelasticsearch module, which is great!  However, unfortunately syslog messages are not always proper UTF-8 (some latin1, some just garbage), and elasticsearch only accepts UTF-8.  Upstream rsyslog has added a "hack" module that strips out non-ASCII, non-UTF-8 characters and replaces them, and that makes the omelasticsearch module much more useful.

I took the mmutf8fix module from upstream version 7.6.4 (along with the necessary Makefile* and configure* changes), and it appears to work just fine with the RHEL 7 rsyslog-7.4.7 package (I actually patched the SRPM to build a new subpackage).  The rsyslog internal interfaces haven't changed between those versions.

Would it be possible for the RHEL package to have the mmutf8fix module added as well?

I *think* it would be possible, but can't say when it would happen.

Created attachment 1131628 [details]
patch backport

Here is the patch.

It can be tested e.g. :

----------------------------------------------------------------

module( load="imuxsock")
input(type="imuxsock" socket="/tmp/socket" createpath="on")


module(load="mmutf8fix")
action(type="omfile" file="/tmp/test_orig.log")
action(type="mmutf8fix")
action(type="omfile" file="/tmp/test_fixed.log")

----------------------------------------------------------------

logger -u /tmp/socket "this is non utf8 character  >>>`echo -e "\xFF"`<<<"

and result will be:

/tmp/test_orig.log:
ibm-x3650m4-01-vm-02 root: this is non utf8 character  >>>ÿ<<<

/tmp/test_fixed.log:
ibm-x3650m4-01-vm-02 root: this is non utf8 character  >>> <<<
