RHBA-2010:0886 - Bug Fix Advisory

Topic

Updated dapl and compat dapl packages that fix various bugs are now available
for Red Hat Enterprise Linux 5.

Description

dapl and compat-dapl provide a userspace implementation of the DAT 1.2 and 2.0
API that is built to natively support InfiniBand/iWARP network technology.

This update fixes the following bugs:

• Previously, an error in the code path in the uDAPL layer did not allow the

cp_ptr entry to be cleaned up correctly in the internal link list. This could
cause new connections to fail. With this update, the entry is cleaned up
correctly and subsequent connections work as expected. (BZ#638594)

• Previously, dapl could leak file descriptors, which could cause an application

crash. With this update, the leak is closed and dapl behaves as expected.
(BZ#638595)

• Previously, verbs CQ and completion channels were not correctly disconnected

and freed, which could cause an application crash. With this update, verbs CQ
and completion channels behave as expected. (BZ#638860)

• Previously, an error in the code path in the compat-dapl layer did not allow

the cp_ptr entry to be cleaned up correctly in the internal link list. This
could cause new connections to fail. With this update, the entry is cleaned up
correctly and subsequent connections work as expected. (BZ#638862)

All users of dapl or compat-dapl are advised to upgrade to these updated
packages which resolve these issues.
