From: Roland Dreier Date: Tue, 5 Jun 2012 06:24:51 +0000 (-0700) Subject: target: Return error to initiator if SET TARGET PORT GROUPS emulation fails X-Git-Tag: v3.5-rc6~5^2~8 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=59e4f541baf728dbb426949bfa9f6862387ffd0e;p=profile%2Fivi%2Fkernel-x86-ivi.git target: Return error to initiator if SET TARGET PORT GROUPS emulation fails The error paths in target_emulate_set_target_port_groups() are all essentially "rc = -EINVAL; goto out;" but the code at "out:" ignores rc and always returns success. This means that even if eg explicit ALUA is turned off, the initiator will always see a good SCSI status for SET TARGET PORT GROUPS. Fix this by returning rc as is intended. It appears this bug was added by the following patch: commit 05d1c7c0d0db4cc25548d9aadebb416888a82327 Author: Andy Grover Date: Wed Jul 20 19:13:28 2011 +0000 target: Make all control CDBs scatter-gather Signed-off-by: Roland Dreier Cc: Andy Grover Cc: Signed-off-by: Nicholas Bellinger --- diff --git a/drivers/target/target_core_alua.c b/drivers/target/target_core_alua.c index e624b83..9179997 100644 --- a/drivers/target/target_core_alua.c +++ b/drivers/target/target_core_alua.c @@ -374,8 +374,9 @@ int target_emulate_set_target_port_groups(struct se_cmd *cmd) out: transport_kunmap_data_sg(cmd); - target_complete_cmd(cmd, GOOD); - return 0; + if (!rc) + target_complete_cmd(cmd, GOOD); + return rc; } static inline int core_alua_state_nonoptimized(
