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.

Doc Type: Bug Fix
Doc Text:
Previously, the name of the network interface was restricted to 4 characters on 32-bit systems and 8 characters on 64-bit system due to using the sizeof() operator instead of the strlen() function. As a consequence, AMTU did not correctly display the full network interface name in certain portions of the output. A patch has been applied to address this bug, and AMTU now always displays the full network interface name as expected.

Comment 5 Jaroslav Aster 2014-05-29 09:14:37 UTC
Hi Paul,

I tested it again and I found out that I can reproduce it only on i686. S390x, PPC64 and x86_64 works fine.

I checked the source code and it seems to be correct, no print limitation, no strncpy limitation, but there is difference between list of interface print and the other prints. They use name of interface from different structure. First print use name of interface from the structure witch is returned by function getifaddrs, the other prints use internal structure. Data is copied into this structure from the structure returned by function getifaddrs. I think the problem could be there.

Okay, I've been able to recreate this by installing amtu.i686 on my x86_64 system.  I'll look into it (thanks for your investigation above) and update this BZ when I have a fix to try.

Comment 7 Paul Moore 2014-05-29 19:38:09 UTC
Just an additional datapoint for my benefit, compiling the amtu sources with '-m32' on x86_64 results in the same flawed behavior (expected, but always worth verification).

Comment 8 Paul Moore 2014-05-29 19:51:16 UTC
Ah ha!  I found the problem.  The issue involves using a sizeof(...) instead of a strlen(...) on a 'char *'; we don't see this on 64-bit systems as the pointer is 8 bytes, which is large enough for the reproducer above, but on 32-bit systems the point is only 4 bytes which is too short.

Fix coming soon ...

Could you verify the above patch on your test system?  It works for me, but having another successful test is always nice.

Comment 13 Jaroslav Aster 2014-05-30 09:02:48 UTC
Hi Paul,

I tested it and it works. Thanks.

I reviewed the patch and I have one comment. strdup is ok, but there is still old comment above it and it does not make sense now.

/* need to malloc size of string plus null terminator */

Comment 14 Paul Moore 2014-05-30 13:12:13 UTC
The comment is still correct, the allocation and copy operations are just abstracted away in the strdup() call.  Regardless, I'll go ahead and remove the comment in the released package as I see how it could be confusing to some.

Expect a final build soon.
