Description Jason McCormick 2010-05-06 20:18:49 UTC
Description of problem:

The kernel shipping with EL6 because implements Integrity Management Architecture (IMA).  It appears that the 2.6.32 kernel provided in EL6 beta has an early, flawed version of the API.  The API only allows GPL modules to call ima_counts_get() with leaves non-GPL modules no way to legitimately use dentry_open() and fput() combinations correctly.  This causes a big problem for, among other things, users of OpenAFS.  Here's the OpenAFS project's description of the problem:


The kernel/IMA developers have acknowledged this problem and addressed the API issues in 2.6.33.  Red Hat, please backport the updated IMA API, notably the following kernel changes into EL6 before its production release:

  0552f879: Untangling ima mess, part 1: alloc_file()
  b65a9cfc: Untangling ima mess, part 2: deal with counters
  1429b3ec: Untangling ima mess, part 3: kill dead code in ima

This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release. It has
been denied for the current Red Hat Enterprise Linux release.

** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **
