RHBA-2012:0252 - dapl bug fix update

Synopsis

dapl bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

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

Description

The dapl package provides a user-space implementation of the DAT 2.0 API that allows applications to utilize high-performance network technologies such as InfiniBand and iWARP.

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#634323)

  • Previously, dapl could leak file descriptors and the application could terminate. With this update, the leak is closed and dapl behaves as expected. (BZ#634324)

  • 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#636193)

  • 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#636197)

  • Under certain circumstances, the dat_ia_open() call and the programs using the function could become unresponsive. With this update, the underlying code has been modified and the function behaves as expected. (BZ#645825)

  • Due to an invalid error mapping, when dapl received a signal during the execution of the dapls_evd_dto_wait() function, it could fail to set the correct error type, which may have led to an incorrect operation. With this update, the relevant part of the source code has been modified to return the correct value, and dapl now works as expected. (BZ#658950)

All dapl users are advised to upgrade to these updated packages, which fix these bugs.
