2008-12-13[SCSI] scsi_lib: only call scsi_unprep_request() under queue lockJames Bottomley
It's called under that lock everywhere else and it does alter the request state, so it should be. This one occurance in scsi_requeue_command() could open a window where req->special is set to NULL while the requests is going through either timeout or completion processing leading to NULL pointer derefs of the sort complained of in bugzillas 12020 and 12195.

2008-12-03[SCSI] libiscsi REGRESSION: fix passthrough support with older iscsi toolsMike Christie
This regression was added in 2.6.27, when the mtask and ctask were merged into the the common task struct. The patch applies to scsi-rc-fixes, but also applies to 2.6.27 with some offsets. The problem is that __iscsi_conn_send_pdu assumes that userspace was not sending nops with the format it is checking for in the "if" below. It turns out that older userspace tools are. This patch moves the setting of the internal ping_task tracker (it tracks libiscsi current outstanding nop) to iscsi_send_nopout which is only used by kernel callers.

scsi_eh_try_stu() was still using the timeout parameter in the device which is now not set (i.e. zero filled) meaning that it waited no time at all for the start unit command to complete (leading the routine to conclude failure every time). This lead to a 2.6.27 regression: http://bugzilla.kernel.org/show_bug.cgi?id=12120 Where firewire devices that were non spec compliant wouldn't spin up.

2008-11-30advansys fix on ISA-less configsAl Viro
The code if (shost->dma_channel != NO_ISA_DMA) free_dma(shost->dma_channel); in there is triggerable only if we have CONFIG_ISA (we only set ->dma_channel to something other than NO_ISA_DMA under #ifdef CONFIG_ISA). OTOH, free_dma() is not guaranteed to be there in absense of CONFIG_ISA. IOW, driver runs into undefined symbols on PCI-but-not-ISA configs (e.g. on frv) and it's a false positive. Fix: put the entire if () under #ifdef CONFIG_ISA; behaviour doesn't change and dependency on free_dma() disappears for !CONFIG_ISA.

2008-11-15[SCSI] dpt_i2o: fix transferred data length for scsi_set_resid()Miquel van Smoorenburg
dpt_i2o.c::adpt_i2o_to_scsi() reads the value at (reply+5) which should contain the length in bytes of the transferred data. This would be correct if reply was a u32 *. However it is a void * here, so we need to read the value at (reply+20) instead. The value at (reply+5) is usually 0xff0000, which is apparently 'large enough' and didn't cause any trouble until 2.6.27 where commit 427e59f09fdba387547106de7bab980b7fff77be Author: James Bottomley <James.Bottomley@HansenPartnership.com> Date: Sat Mar 8 18:24:17 2008 -0600 [SCSI] make use of the residue value caused this to become visible through e.g. iostat -x .

2008-11-05[SCSI] scsi_error regression: Fix idempotent command handlingMike Christie
Drivers want to be able to return DID_TRANSPORT_DISRUPTED and have it do the right thing for commands like tape and passthrouh as far as retries go. The LLDs previously used DID_BUS_BUSY or DID_ERROR which followed the cmd->retries limit, but DID_TRANSPORT_DISRUPTED was skipping that check so it could have caused a problem with tape commands.

2008-11-05[SCSI] qla2xxx: Return a FAILED status when abort mailbox-command fails.Michael Reed
Mike Reed noted (https://bugzilla.novell.com/show_bug.cgi?id=421330) that the driver was incorrectly returning a SUCCESS status if the driver's request to the firmware to abort a command failed. By doing so, the mid-layer believed, incorrectly, that the command has completed and has been returned (ultimately clearing scsi_cmnd.request_buffer) yet the driver still has the command. What should correctly happen is a mid-layer escalation (device-reset, etc.) of recovery during which the driver will eventually return the outstanding commands to the mid-layer.

2008-11-05[SCSI] megaraid: fix mega_internal_command oopsFUJITA Tomonori
scsi_cmnd->cmnd was changed from a static array to a pointer post 2.6.25. It breaks mega_internal_command(): static int mega_internal_command(adapter_t *adapter, megacmd_t *mc, mega_passthru *pthru) { ... scb = &adapter->int_scb; memset(scb, 0, sizeof(scb_t)); scmd = &adapter->int_scmd; memset(scmd, 0, sizeof(Scsi_Cmnd)); sdev = kzalloc(sizeof(struct scsi_device), GFP_KERNEL); scmd->device = sdev; scmd->device->host = adapter->host; scmd->host_scribble = (void *)scb; scmd->cmnd[0] = MEGA_INTERNAL_CMD; mega_internal_command() uses scsi_cmnd allocated internally so scmd->cmnd is NULL here. This patch adds a static array for cdb to adapter_t and uses it here. This also uses scsi_allocate_command/scsi_free_command, the recommended way to allocate struct scsi_cmnd since the driver might use sense_buffer in struct scsi_cmnd.

2008-11-01saner FASYNC handling on file closeAl Viro
As it is, all instances of ->release() for files that have ->fasync() need to remember to evict file from fasync lists; forgetting that creates a hole and we actually have a bunch that *does* forget. So let's keep our lives simple - let __fput() check FASYNC in file->f_flags and call ->fasync() there if it's been set. And lose that crap in ->release() instances - leaving it there is still valid, but we don't have to bother anymore.

This patch (as1138) removes from sd.c some old code for switching from 10-byte commands to 6-byte commands. This code is redundant -- the switching for READ and WRITE is already handled in scsi_io_completion() and the switching for MODE SENSE is already handled in scsi_mode_sense(). (There is no comparable switch for MODE SELECT, but I doubt one is needed.) Furthermore the other handlers do a better job; they check for appropriate ASC and ASCQ values before blindly switching the size. The code in sd.c is known to cause problems with some devices by switching when it shouldn't.

The current handling of NO_SENSE check condition is the same as RECOVERED_ERROR, and assumes that in both cases, the I/O was fully transferred. We have seen cases of arrays returning with NO_SENSE (no error), but the I/O was not completely transferred, thus residual set. Thus, rather than return good_bytes as the entire transfer, set good_bytes to 0, so that the midlayer then applies the residual in calculating the transfer, and for sd, will fail the I/O and fall into a retry path.

This patch implements q->lld_busy_fn() for scsi mid layer to export its busy state for request stacking drivers. For efficiency, no lock is taken to check the busy state of shost/starget/sdev, since the returned value is not guaranteed and may be changed after request stacking drivers call the function, regardless of taking lock or not. When scsi can't dispatch I/Os anymore and needs to kill I/Os (e.g. !sdev), scsi needs to return 'not busy'. Otherwise, request stacking drivers may hold requests forever.

2008-10-23[SCSI] aic7xxx: Take the LED out of diagnostic mode on PM resumethomas schorpp
Take the Diag/Activity-LED of the HBA out of diagnostic mode on PM resume after successful PM resume from standby and HBA restart, it remained always on before. If something fails before complete recovery, it should remain on, since it is a diagnostics LED, reason for the used higher layer for the clear.
