[PATCH v3] [SCSI] scsi_debug: silence GCC warning

2013-07-17 Thread Paul Bolle
Building scsi_debug.o triggers a GCC warning: drivers/scsi/scsi_debug.c: In function ‘dif_verify’: drivers/scsi/scsi_debug.c:1755:3: warning: ‘csum’ may be used uninitialized in this function [-Wmaybe-uninitialized] This warning was apparently introduced (in v3.11-rc1) by commit beb40ea42

[PATCH v4 0/4] [SCSI] sg: fix race condition in sg_open

2013-07-17 Thread Vaughan Cao
There is a race when open sg with O_EXCL flag. Also a race may happen between sg_open and sg_remove. Changes from v3: * release o_sem in sg_release(), not in sg_remove_sfp(). * not set exclude with sfd_lock held. Vaughan Cao (4): [SCSI] sg: use rwsem to solve race during exclusive open [SCS

[PATCH v4 2/4] [SCSI] sg: no need sg_open_exclusive_lock

2013-07-17 Thread Vaughan Cao
Open exclusive check is protected by o_sem, no need sg_open_exclusive_lock. @exclude is used to record which type of rwsem we are holding. Signed-off-by: Vaughan Cao --- drivers/scsi/sg.c | 34 +- 1 file changed, 5 insertions(+), 29 deletions(-) diff --git a/driv

[PATCH v4 3/4] [SCSI] sg: checking sdp->detached isn't protected when open

2013-07-17 Thread Vaughan Cao
@detached is set under the protection of sg_index_lock. Without getting the lock, new sfp will be added during sg removal and there is no chance for it to be picked out. So check with sg_index_lock held in sg_add_sfp(). Signed-off-by: Vaughan Cao --- drivers/scsi/sg.c | 26 ++

Push file descriptor list locking down to per-device locking. Let sg_index_lock only protect device lookup. sdp->detached is also set and checked with this lock held. Signed-off-by: Vaughan Cao --- drivers/scsi/sg.c | 61 ++- 1 file changed, 33

[PATCH v4 1/4] [SCSI] sg: use rwsem to solve race during exclusive open

2013-07-17 Thread Vaughan Cao
A race condition may happen if two threads are both trying to open the same sg with O_EXCL simultaneously. It's possible that they both find fsds list is empty and get_exclude(sdp) returns 0, then they both call set_exclude() and break out from wait_event_interruptible and resume open. Now use rws
