* [SCSI] libfc: Correct use of ! and &Julia Lawall2009-03-12
| | | | | | | | | | | | | | | | | | | | | | !ep->esb_stat is either 1 or 0, and the rightmost bit of ESB_ST_COMPLETE is always 0, making the result of !ep->esb_stat & ESB_ST_COMPLETE always 0. Thus parentheses around the argument to ! seem needed.

* [SCSI] libosd: Fix NULL dereference BUG when target is not OSD conformantBoaz Harrosh2009-03-12
| | | | | | | | | | | | | Very old OSC's Target had a BUG in the Get/Set attributes where it was looking in the wrong places for attribute lists length. If used with the open-osd initiator, the initiator would dereference a NULL pointer when retrieving system_information attributes. Checks are added that retrieval of each attribute is successful before accessing its value.

* [SCSI] sg: avoid blk_put_request/blk_rq_unmap_user in interruptFUJITA Tomonori2009-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the following oops: http://marc.info/?l=linux-kernel&m=123316111415677&w=2 You can reproduce this bug by interrupting a program before a sg response completes. This leads to the special sg state (the orphan state), then sg calls blk_put_request in interrupt (rq->end_io). The above bug report shows the recursive lock problem because sg calls blk_put_request in interrupt. We could call __blk_put_request here instead however we also need to handle blk_rq_unmap_user here, which can't be called in interrupt too. In the orphan state, we don't need to care about the data transfer (the program revoked the command) so adding 'just free the resource' mode to blk_rq_unmap_user is a possible option. I prefer to avoid complicating the blk mapping API when possible. I change the orphan state to call sg_finish_rem_req via execute_in_process_context. We hold sg_fd->kref so sg_fd doesn't go away until keventd_wq finishes our work. copy_from_user/to_user fails so blk_rq_unmap_user just frees the resource without the data transfer.

* [SCSI] ibmvfc: Better handle other FC initiatorsBrian King2009-03-12
| | | | | | | | | | | | | | The ibmvfc driver currently always sets the role of all rports to FC_PORT_ROLE_FCP_TARGET, which is not correct for other initiators. This can cause problems if other initiators are on the fabric when we then try to scan the rport for LUNs. Fix this by looking at the service parameters returned in the PRLI to set the roles appropriately. Also look at the returned service parameters to decide whether or not we were actually able to successfully log into the target.

* [SCSI] osd_uld: API for retrieving osd devices from KernelBoaz Harrosh2009-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kernel clients like exofs can retrieve struct osd_dev(s) by means of below API. + osduld_path_lookup() - given a path (e.g "/dev/osd0") locks and returns the corresponding struct osd_dev, which is then needed for subsequent libosd use. + osduld_put_device() - free up use of an osd_dev. Devices can be shared by multiple clients. The osd_uld_device's life time is governed by an embedded kref structure. The osd_uld_device holds an extra reference to both it's char-device and it's scsi_device, and will release these just before the final deallocation. There are three possible lock sources of the osd_uld_device 1. First and for most is the probe() function called by scsi-ml upon a successful login into a target. Released in release() when logout. 2. Second by user-mode file handles opened on the char-dev. 3. Third is here by Kernel users. All three locks must be removed before the osd_uld_device is freed. The MODULE has three lock sources as well: 1. scsi-ml at probe() time, removed after release(). (login/logout) 2. The user-mode file handles open/close. 3. Import symbols by client modules like exofs. TODO: This API is not enough for the pNFS-objects LD. A more versatile API will be needed.

* [SCSI] sg: fix races with ioctl(SG_IO)Tony Battersby2009-03-12
| | | | | | | | | | | | | | | | | | | | sg_io_owned needs to be set before the command is sent to the midlevel; otherwise, a quickly-completing command may cause a different CPU to see "srp->done == 1 && !srp->sg_io_owned", which would lead to incorrect behavior. Check srp->done and set srp->orphan while holding rq_list_lock to prevent races with sg_rq_end_io(). There is no need to check sfp->closed from read/write/ioctl/poll/etc. since the kernel guarantees that this won't happen. The usefulness of sg_srp_done() was questionable before; now it is definitely not needed.

* [SCSI] sg: fix races during device removalTony Battersby2009-03-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sg has the following problems related to device removal: * opening a sg fd races with removing a device * closing a sg fd races with removing a device * /proc/scsi/sg/* access races with removing a device * command completion races with removing a device * command completion races with closing a sg fd * can rmmod sg with active commands These problems can cause kernel oopses, memory-use-after-free, or double-free errors. This patch fixes these problems by using krefs to manage the lifetime of sg_device and sg_fd. Each command submitted to the midlevel holds a reference to sg_fd until the completion callback. This ensures that sg_fd doesn't go away if the fd is closed with commands still outstanding. sg_fd gets the reference of sg_device (with scsi_device) and also makes sure that the sg module doesn't go away. /proc/scsi/sg/* functions don't play nicely with krefs because they give information about sg_fds which have been closed but not yet freed due to still having outstanding commands and sg_devices which have been removed but not yet freed due to still being referenced by one or more sg_fds. To deal with this safely without removing functionality, /proc functions now access sg_device and sg_fd while holding a lock instead of using kref_get()/kref_put().
