Tom, please attach the straces I sent you last week to this BZ. Thank you, Wayne. Great - i'll get those fixes into the tree. I'm a bit confused about the comment about the stack being corrupted though. Once iscsi-ls has ended, it's stack space has been closed. Are you saying the iscsi driver's stack space is getting corrupted by iscsi-ls? In test I found that if I removed PowerPath after the segmentation fault occurred, subsequent iscsi-ls -l calls would yield a segmentation fault; however, if I started with a fresh server without PowerPath running iscsi-ls -l works fine in the same configuration without any faults. Created attachment 114768 [details]
iscsi-ls -l trace before PowerPath is started
Created attachment 114769 [details]
iscsi-ls -l trace after PowerPath is started
This is an strace of the failure with PowerPath running.
Created attachment 114770 [details]
iscsi-ls -l trace after PowerPath is stopped but after the seg fault
This is a trace of the seg fault after PowerPath has been stopped but the
server has not been rebooted. iscsi-ls -l will continue to seg fault until the
server has been rebooted.
Memory allocation fixes committed to the 3.6 upstream tree. Patch tested successfully. RHEL 3.0 U6 beta (lk 2.4.21-35) in test to confirm fix. An advisory has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA.
