This is probably a dup of: * Thu Mar 20 2008 Eric Sandeen <esandeen> 1.35-12.15.EL4 - Fix aliasing violation causing dumpe2fs segfaults in ia64 (#433784) see bug 433784 for more info; this should be part of the upcoming rhel4.7 update. If you'd like, you can grab http://people.redhat.com/esandeen/e2fsprogs-1.35-12.17.el4.src.rpm and rebuild to verify that it's addressing your problem. Thanks, -Eric I'm not very familiar with building rpm-packages, but after running rpmbuild --recompile e2fsprogs-1.35-12.17.el4.src.rpm /var/tmp/e2fsprogs-root/sbin/badblocks -b 512 /dev/sda 780132465 still segfaults. Created attachment 312149 [details]
mostly-static badblocks
that badblocks probably still links with the older problematic libraries.
Here's a badblocks from e2fsprogs-1.35-12.17.el4, statically linked with all
the e2fsprogs libraries. Can you verify that it does not segfault?
Thanks,
-Eric
The mostly-statically linked version does not segfault. |
Description of problem: Running e.g. '/sbin/badblocks -b 512 /dev/sda 780132465' segfaults. with strace it ends like this: mprotect(0x33e862c000, 12288, PROT_READ) = 0 mprotect(0x33e8314000, 4096, PROT_READ) = 0 arch_prctl(ARCH_SET_FS, 0x2a95569320) = 0 munmap(0x2a95557000, 66763) = 0 brk(0) = 0x505000 brk(0x526000) = 0x526000 open("/dev/sda", O_RDONLY) = 3 --- SIGSEGV (Segmentation fault) @ 0 (0) --- +++ killed by SIGSEGV +++ Version-Release number of selected component (if applicable): server# rpm -qf /sbin/badblocks e2fsprogs-1.35-12.11.el4_6.1 server# How reproducible: Every time. I've tested on two brand new Dell 2950's and one HP DL585 G5. Steps to Reproduce: 1./sbin/badblocks -b 512 /dev/sda 780132465 Actual results: server# /sbin/badblocks -b 512 /dev/sda 780132465 Segmentation fault server# Expected results: Not segfaulting. :) Additional info: http://bugs.centos.org/view.php?id=2631 Works fine on a RHEL5 x86_64 installation.
