Description Miroslav Vadkerti 2016-04-18 14:12:41 UTC
Description of problem:

This package is showing ABI changes which need your attention. Note that this package is on ABI compatibility list [1] in level 1. The ABI changes were tested using libabigail - abipkgdiff [2], only for subpackage:

    pam

See

    http://gov-cert.brq.redhat.com/abidiff/results/level1_72vs70/72vs70_pam-1.1.8-9.el7_vs_pam-1.1.8-12.el7_1.1_pam.txt

for detailed results from the scan. Note that the results are merged for all architectures, thus there can be some duplicity.

To reproduce the issue run the abipkgdiff on the reported package pam:

    $ abipkgdiff --d1 OLD_DEBUGINFO --d2 NEW_DEBUGINFO OLD_RPM NEW_RPM

See the tool documentation for more information [2].

***What is action is required from the assignee of this bugzilla?***

Comment 3 Tomas Mraz 2016-04-19 08:10:34 UTC
I do not see any real ABI changes in the report at all. Note that the report incorrectly includes scanning of private data structures that are not published for consumption of external users of libpam and changes of binaries which are not libraries at all so they are irrelevant for ABIDIFF. Please ensure that future reports compare only changes in public API of libpam, libpam_misc and libpamc.
