Description Roland McGrath 2005-01-14 02:11:16 UTC 
*** This bug has been split off bug 132162 ***

------- Original comment by David Juran on 2004.09.09 10:07 -------

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.3)

Description of problem:
A process having it's working directory on an NFS filesystem mounted
with the 'intr' flag receiving a SIGSEGV will produce no core dump

Version-Release number of selected component (if applicable):
kernel-smp-2.4.21-20.EL

How reproducible:
Always

Steps to Reproduce:
1. mount -o 'rw,proto=tcp,intr' filadelfia.carmen.se:/raidtest /mnt/test
2. cd /mnt/test
3. cat > foo&
4. killall -11 cat
5. Note that no core dump was produced
6. Now try again, this time without the 'intr' flag and there will be
a nice core file waiting for you

Comment 2 Roland McGrath 2005-01-14 02:13:38 UTC 
This problem was first reported in bug #132162 for the RHEL3 backport of the
NPTL code that contains this bug.  

This report tracks my upstream fix, please don't close until the patch is in an
upstream release.
Comment 3 Roland McGrath 2005-01-18 23:12:25 UTC 
My patch went in upstream, should be in 2.6.11 when that comes out.
Comment 4 Roland McGrath 2005-08-09 07:09:25 UTC 
All good in FC4.
