It seems that certain kinds of corrupted incoming packets will cause tgtd to crash with a segfault:
Feb 16 11:54:01 hostname kernel: tgtd[21178]: segfault at fffffffffffffff0 ip 00000000004086b0 sp 00007fff3ca9eaf0 error 4 in tgtd[400000+3e000]
Feb 16 11:54:01 hostname tgtd: iscsi_rx_handler(2107) rx hdr digest error 0xe5e46fae calc 0xd8d8e323
Feb 16 11:54:01 hostname tgtd: conn_close(101) connection closed, 0x1d28568 23
Feb 16 11:54:01 hostname tgtd: conn_close(107) sesson 0x1d281b0 1
Feb 16 11:54:01 hostname tgtd: conn_close(165) Forcing release of rx task 0x1da52c0 9d0c0000
Output from abrt for this crash attached. (Sorry if there isn't enough info in there to track this down -- I might be able to re-create the crash later with more trace info, but have little free time lately.)
This was with the latest scsi-target-utils package available for CentOS 6.6.
Some background that may be helpful in reproducing this:
I was able to reproduce this crash several times, and the root cause of the corrupted packets is a bug in either VMWare ESXi 5.1 or Windows Server 2012. We have a Windows Server 2012 virtual machine that connects to an iSCSI volume served by tgtd on a physical Linux (CentOS) machine. Windows uses this volume as its backup target, and backups were failing partway through, often causing the Windows machine to spontaneously reboot, and tgtd was logging a lot of rx digest errors whenever any significant amount of data was transferred.
All three problems -- data corruption on the wire, the Windows initiator crashing Windows, and tgtd segfaulting -- were solved by disabling TCP and IP checksum offloads in the virtual NIC driver in Windows. VMware uses a specialised set of rules to determine when offloaded checksums are calculated, and sometimes does not calculate TCP checksums until well after the packet has left the source machine; I strongly suspect a bug in this mechanism was messing up the iSCSI packets.
Still, tgtd should not be crashing with a segfault on receiving bad data; it should (at worst) force the connection closed but otherwise remain in a good state.
