patch to catch and report malloc failure and return gracefully none

Description Chris Snook 2006-11-22 05:48:46 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.7) Gecko/20060911 Red Hat/1.5.0.7-0.1.el4 Firefox/1.5.0.7 pango-text

Description of problem:
Reported upstream:

http://sources.redhat.com/bugzilla/show_bug.cgi?id=3559

my_pollfd malloc() is unchecked, which could result in a segmentation fault.

Version-Release number of selected component (if applicable):
all current RHEL and Fedora versions

How reproducible:
Didn't try


Steps to Reproduce:
The bug is not easily reproducible on demand, but could be responsible for some unexplained ypbind crashes.

Actual Results:
An ill-timed malloc() failure would cause a segmentation fault.

Expected Results:
The failure should be caught and reported, and the function should return gracefully to permit the calling application to handle it.

Additional info:
This was discovered by code inspection while troubleshooting ypbind.

Comment 2 Jakub Jelinek 2006-11-29 19:04:54 UTC 
Should be fixed in glibc-2.5-6 in dist-5E.
Comment 3 RHEL Program Management 2006-11-29 19:30:24 UTC 
This request was evaluated by Red Hat Product Management for inclusion in a Red
Hat Enterprise Linux major release.  Product Management has requested further
review of this request by Red Hat Engineering, for potential inclusion in a Red
Hat Enterprise Linux Major release.  This request is not yet committed for
inclusion.
Comment 4 Paul Dickson 2006-12-01 14:57:08 UTC 
Would this change be causing bug#218036.  The changelog for glibc-2.5.90-8 is
rather short.
Comment 5 Jay Turner 2007-01-11 02:42:48 UTC 
QE ack for RHEL5.
Comment 6 RHEL Program Management 2007-02-08 00:46:28 UTC 
A package has been built which should help the problem described in 
this bug report. This report is therefore being closed with a resolution 
of CURRENTRELEASE. You may reopen this bug report if the solution does 
not work for you.
