RHBA-2011:0695 - dapl bug fix update

Synopsis

dapl bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated dapl packages that fix multiple bugs are now available for Red Hat Enterprise Linux 6.

Description

The dapl package provides a user space implementation of the DAT 2.0 API, and is built to natively support InfiniBand/iWARP network technology.

This update fixes the following bugs:

  • Under certain circumstances, when a thread was waiting on dapls_evd_dto_wait() and the thread received a signal, the function would return an incorrect error code, resulting in the application failing rather than retrying the request. (BZ#626541)

  • Previously, the function dapls_evd_dto_wait() returned, under certain circumstances, an error code when a thread was waiting on the function and the thread received a signal. Due to this behavior, the application failed. With this update, the application retries the request. (BZ#626541)

  • Red Hat Enterprise Linux 6 already supports a feature called "RoCE" (RDMA over converged Ethernet). Previously, applications that utilize uDAPL could not use the RDMA over converged Ethernet (RoCE) feature. This update adds these additional entries to the dat.conf file. (BZ#636596)

  • The dat_ia_open() function could, under under certain circumstances, fail to return. With this update, the function returns as expected. (BZ#649360)

  • Under certain circumstances dapl could fail to clean up its internal state, resulting in subsequent usage of the library to fail. With this update, the internal state is cleaned up as expected and the library can be used without further problems. (BZ#667742)

  • Previously, dapl could, under certain circumstances, fail to free allocated memory, potentially causing the application to run out of memory and fail. Now, dapl frees all allocated memory. (BZ#637980)

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