Bug ID: 216906
Summary: [iSCSI] Bad CRC may not be correctly handled
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: freebsd-bugs at FreeBSD.org
Reporter: ben.rubson at gmail.com
Hello,
Adding hardware CRC32C support to FreeBSD (#216467), we found that iSCSI CRC
errors may not be correctly handled.
When one of the patch #216467 versions generated bad CRC, here is how the iSCSI
test disk behaved :
disk connected successfully (here the CRC were certainly right), but as soon as
there were some trafic, disk hung, and it was not possible to recover it,
reboot needed.
>From /var/log/messages :
kernel: WARNING: 192.168.2.1 (iqn.2012-06.srv1:rT1): no ping reply (NOP-In)
after 5 seconds; reconnecting
srv1 last message repeated 31 times
srv1 last message repeated 42 times
No digest failed message.
Should we try to reproduce / investigate on this ?
Many thanks !
Ben
