| * [libata] sata_mv: errata check buglet fixAndres Salomon2006-09-11
| | | | | | | | | | | | | | | | | | | | | | | | Fix a buglet; the errata check below this code is assuming the value in the sstatus variable is what was pulled out of the SCR_STATUS register. However, the status checks in the timeout loop clobber everything but the first 4 bits of sstatus, so the errata checks are invalid. This patch changes it to not clobber SStatus.

| | | | | | | | | | | | idescsi_pc_intr() uses local_irq_enable() in IRQ context: annotate it. (this has no effect on kernels with lockdep disabled. On kernels with lockdep enabled this means that we wont actually disable interrupts, and the warning message will go away as well.)

| * [SCSI] fix scsi_send_eh_cmnd regressionMike Christie2006-08-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The callers of scsi_send_eh_cmnd are setting the cmnd buffer, and then scsi_send_eh_cmnd is copying that updated buffer to the old_cmnd variable. Then after the command runs, we end up copying that old_cmnd var which has the new cmnd to the scsi command buffer. When this command gets recent, all types of fun things happen like getting TUR or START_STOP commands with data and scatterlists. This patch made against scsi-rc-fixes, has the callers of scsi_send_eh_cmnd pass in the command so scsi_send_eh_cmnd can do the right thing. This should go into 2.6.18 since this fixes a regression added when we removed some of the scsi_cmnd fields and replaced them with local variables.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Original code attempts to retry PLOGIs to fcports that are FCP_TARGETs only. If the driver never performed a successful PLOGI/PRLI, the port-type would never be assigned, and the relogin logic would silently drop the request (and thus the port would not be recognized and registered). The fix is relatively straightforward, drop the FCP_TARGET-only check. Signed-off-by: Andrew Vasquez <andrew.vasquez@qlogic.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| * [SCSI] lpfc 8.1.9 : Stall eh handlers if resetting while rport blockedJames Smart2006-08-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Stall error handler if attempting resets/aborts while an rport is blocked. This avoids device offline scenarios due to errors in the error handler. Background: Although the transport is using the scsi_timed_out functionality to restart the timeout if the rport is blocked, if the timeout has already fired before the block occurs, the eh handler still runs and can take the device offline. Ultimately, this window cannot be resolved without significant work in the error handler thread. Christoph noted the first level of these issues when he noted the poor error response handling by the error thread. We found, under heavy load and error testing, that time window from when the scsi_times_out() adds the io to the queue to when the scsi_error_handler gets around to servicing it, can be in the several seconds range. In most cases, these test conditions are highly unusual, but possible. As a result, we're stalling the error handler in this race window so that we can avoid the device_offline transitions.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently it is impossible to reset provided by Qlogic QLA2xxx driver SCSI devices externally using corresponding sg devices, particularly via sg_reset utility, because qla2xxx driver in qla2xxx_eh_device_reset() function checks if the input scsi_cmnd has its private data (CMD_SP()) attached. Then the found pointer isn't used anywhere inside of qla2xxx_eh_device_reset(). If the RESET request comes from sg device, it doesn't have such private data. The attached patch removes check for non-NULL CMD_SP() from qla2xxx_eh_device_reset(), hence allows to reset QLA2xxx's devices using corresponding sg devices.
