| * [SCSI] fusion: fix domain validation loopsEric Moore2007-04-30
| | | | | | | | | | | | | | | | | | | | | | | | | | After host reset, the device are programmed to default asyn narrow nego. We need to reprogram the parameter back to previous values. If the host reset is called as a result of spi_dv_device() commands timing out, its possible to get into an infinite loop of dv to host reset. This will prevent that case, as we merely program old values. If host reset is called outside context of domain validation, then we can call spi_dv_device.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some sparc64 boxes don't have a valid NVRAM (from which the driver takes its WWPN) try to extract this from open firmware instead and if that fails, fall back to a default, which would be invalid if more than one machine on the same SAN does this, since two machines with the same WWPN would be illegal, so warn when taking this potentially invalid default.

| * [SCSI] modalias for scsi devicesMichael Tokarev2007-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following patch adds support for sysfs/uevent modalias attribute for scsi devices (like disks, tapes, cdroms etc), based on whatever current sd.c, sr.c, st.c and osst.c drivers supports. The modalias format is like this: scsi:type-0x04 (for TYPE_WORM, handled by sr.c now). Several comments. o This hexadecimal type value is because all TYPE_XXX constants in include/scsi/scsi.h are given in hex, but __stringify() will not convert them to decimal (so it will NOT be scsi:type-4). Since it does not really matter in which format it is, while both modalias in module and modalias attribute match each other, I descided to go for that 0x%02x format (and added a comment in include/scsi/scsi.h to keep them that way), instead of changing them all to decimal. o There was no .uevent routine for SCSI bus. It might be a good idea to add some more ueven environment variables in there. o osst.c driver handles tapes too, like st.c, but only SOME tapes. With this setup, hotplug scripts (or whatever is used by the user) will try to load both st and osst modules for all SCSI tapes found, because both modules have scsi:type-0x01 alias). It is not harmful, but one extra module is no good either. It is possible to solve this, by exporting more info in modalias attribute, including vendor and device identification strings, so that modalias becomes something like scsi:type-0x12:vendor-Adaptec LTD:device-OnStream Tape Drive and having that, match for all 3 attributes, not only device type. But oh well, vendor and device strings may be large, and they do contain spaces and whatnot. So I left them for now, awaiting for comments first.

| * [SCSI] sg: cap reserved_size values at max_sectorsAlan Stern2007-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as857) modifies the SG_GET_RESERVED_SIZE and SG_SET_RESERVED_SIZE ioctls in the sg driver, capping the values at the device's request_queue's max_sectors value. This will permit cdrecord to obtain a legal value for the maximum transfer length, fixing Bugzilla #7026. The patch also caps the initial reserved_size value. There's no reason to have a reserved buffer larger than max_sectors, since it would be impossible to use the extra space. The corresponding ioctls in the block layer are modified similarly, and the initial value for the reserved_size is set as large as possible. This will effectively make it default to max_sectors. Note that the actual value is meaningless anyway, since block devices don't have a reserved buffer. Finally, the BLKSECTGET ioctl is added to sg, so that there will be a uniform way for users to determine the actual max_sectors value for any raw SCSI transport.

| | | | | | | | | | | | | | | | | | | | | | | | | | Thanks for the help from Steve Fox and Duane Cox investigating this issue, I'd like to report that we found the problem. The issue is with the patch Steve Fox isolated below, by not accommodating older adapters properly and issuing a command they do not support when retrieving storage parameters about the arrays.

| * [SCSI] scsi_error.c: Add EH Start Unit retryBrian King2007-04-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the scsi error handler will issue a START_UNIT command if the drive indicates it needs its motor started and the allow_restart flag is set in the scsi_device. If, after the scsi error handler invokes a host adapter reset due to error recovery, a device is in a unit attention state AND also needs a START_UNIT, that device will be placed offline. The disk array devices on an ipr RAID adapter will do exactly this when in a dual initiator configuration. This patch adds a single retry to the EH initiated START_UNIT.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kexec test. Attached is the patch I feel will address this issue. As an added 'perk' I have also added the code to detect if the controller was previously initialized for interrupted operations by ANY operating system should the reset_devices kernel parameter not be set and we are dealing with a naïve kexec without the addition of this kernel parameter. The reset handler is also improved. Related to reset operations, but not pertinent specifically to this issue, I have also altered the handling somewhat so that we reset the adapter if we feel it is taking too long (three minutes) to start up. We have not unit tested the reset_devices flag propagation to this driver code, nor have we unit tested the check for the interrupted operations under the conditions of a naively issued kexec. We are submitting this modified driver to our Q/A department for integration testing in our current programs. I would appreciate an ACK to this patch should it resolve the issue described in this thread...

| * [SCSI] ipr: Fix for oops following SATA request senseBrian King2007-04-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a problem discovered on a system with some bad SATA devices attached. If a command to a SATAPI device times out and the device gets reset as part of error recovery, its possible that ipr will set err_mask to indicate a device error has occurred. If this happens, a request sense will get issued by libata. Since scsi core thinks this scsi command is now completed, because the device reset handler completed successfully, scsi core will free the associated scsi command, which may cause an oops when that request sense is completed later by ipr. This patch ensures that any commands that get aborted as a result of a device reset set err_mask appropriately so that the request sense does not get sent.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Adapter build date that is to be printed on instantiation was not displayed as a result of the supplemental adapter information structure not being in sync with the Firmware; the driver took an early test cycle version that had a miss-sized padded region at the head and the structure was not re-checked at the end of qualification. The Build Date was not a priority and is merely a cosmetic enhancement, and the wrong location for the start of the structure member would not induce any side-effect problems. We updated the structure to match the actual format, and added the TSID (Tech Support Identification) value print, should it be present, to the adapter instantiation announcements during driver load. This later enhancement should improve the relationship between Service folk & Tech Support if the printed value of the TSID found it's way into the circular file labeled G...

Then we do: Length -= (3+i); And since Length is unsigned it becomes very large and we loop forever in the encapsulating: while (Length > 0) { If we make Length signed then we fall out of the loop and proceed on.

| * [SCSI] fusion: remove VMWare guest OS remounted as read only work aroundEric Moore2007-03-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This address the issue of VMWare guest OS being remounted as read-only becuase the underlying device was held busy too long and at the same time address Engenio MPP driver concerns over infinite retries. This patch removes the code that snoops the SAM STATUS on busy, which would be returning DID_BUS_BUSY, instead we return the status as is. Retry hanlding seems to be properly handled in scsi_softirq_done, where a busy sam status would only occurr for the time specified by (cmd->allowed +1) * cmd->timeout_per_command.

| * [SCSI] expose eh_timed_out to the host templateJames Bottomley2007-03-20
| | | | | | | | | | | | | | | | | | It looks like megaraid_sas at least needs this to throttle its commands as they begin to time out. The code keeps the existing transport template use of eh_timed_out (and allows the transport to override the host if they both have this callback).
