| Fixed In Version: | sos-2.2-30.el6 | Doc Type: | Bug Fix | |
| Doc Text: |
Cause:
Previous versions of sos did not sanitize the system hostname for forbidden characters when using the name in file system paths.
Consequence:
Inserting path separators and other special characters in the system hostname would cause sos to generate invalid file system paths and fail to generate a report.
Fix:
Invalid characters are now filtered out of the system hostname.
Result:
The sosreport command now works correctly on systems having characters disallowed in file system paths present in the hostname.

This request was not resolved in time for the current release. Red Hat invites you to ask your support representative to propose this request, if still desired, for consideration in the next release of Red Hat Enterprise Linux. This request was erroneously removed from consideration in Red Hat Enterprise Linux 6.4, which is currently under development. This request will be evaluated for inclusion in Red Hat Enterprise Linux 6.4. While I think we're unlikely to come across it very often this is potentially a bit nasty - weird characters in the hostname can cause us to go wandering off around the file system in strange ways. I've added a filter to the hostname to only accept alphanumeric, dots, dashes and underscores. That's more strict than it really needs to be but leaves less potential for trouble. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. http://rhn.redhat.com/errata/RHBA-2013-0474.html |
Description of problem: When there is no rhn systemid and --name parameter was not used, hostname is used as a part of sosreport tarball name. sosreport should handle this hostname more carefully to handle wrong hostnames in a sane way. # hostname 'f/t_u-r:!§@#$%^>._ha_*()=+"`;/\?~|}{][hěščÁŤďh hh' # sosreport --batch -o general sosreport (version 2.2) This utility will collect some detailed information about the hardware and setup of your Red Hat Enterprise Linux system. The information is collected and an archive is packaged under /tmp, which you can send to a support representative. Red Hat Enterprise Linux will use this information for diagnostic purposes ONLY and it will be considered confidential information. This process may take a while to complete. No changes will be made to your system. Running plugins. Please wait ...
