* [SCSI] atp870u: reduce huge stack usageRandy Dunlap2006-06-281-74/+83
| | | | | | | | | | | | | The atp870u driver is the largest stack eater reported by checkstack (on x86_864, allmodconfig). This converts the offending function to kmalloc+kfree struct atp_unit instead of allocating it on the stack.

* [SCSI] scsi: Device scanning oops for offlined devices (resend)Brian King2006-06-282-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a device gets offlined as a result of the Inquiry sent during scanning, the following oops can occur. After the disk gets put into the SDEV_OFFLINE state, the error handler sends back the failed inquiry, which wakes the thread doing the scan. This starts a race between the scanning thread freeing the scsi device and the error handler calling scsi_run_host_queues to restart the host. Since the disk is in the SDEV_OFFLINE state, scsi_device_get will still work, which results in __scsi_iterate_devices getting a reference to the scsi disk when it shouldn't. The following execution thread causes the oops: CPU 0 (scan) CPU 1 (eh) --------------------------------------------------------- scsi_probe_and_add_lun .... scsi_eh_offline_sdevs scsi_eh_flush_done_q scsi_destroy_sdev scsi_device_dev_release scsi_restart_operations scsi_run_host_queues __scsi_iterate_devices get_device scsi_device_dev_release_usercontext scsi_run_queue <---OOPS---> The patch fixes this by changing the state of the sdev to SDEV_DEL before doing the final put_device, which should prevent the race from occurring. Original oops follows: Badness in kref_get at lib/kref.c:32 Call Trace: [C00000002F4476D0] [C00000000000EE20] .show_stack+0x68/0x1b0 (unreliable) [C00000002F447770] [C00000000037515C] .program_check_exception+0x1cc/0x5a8 [C00000002F447840] [C00000000000446C] program_check_common+0xec/0x100 Exception: 700 at .kref_get+0x10/0x28 LR = .kobject_get+0x20/0x3c [C00000002F447B30] [C00000002F447BC0] 0xc00000002f447bc0 (unreliable) [C00000002F447BB0] [C000000000254BDC] .get_device+0x20/0x3c [C00000002F447C30] [D000000000063188] .scsi_device_get+0x34/0xdc [scsi_mod] [C00000002F447CC0] [D0000000000633EC] .__scsi_iterate_devices+0x50/0xbc [scsi_mod] [C00000002F447D60] [D00000000006A910] .scsi_run_host_queues+0x34/0x5c [scsi_mod] [C00000002F447DF0] [D000000000069054] .scsi_error_handler+0xdb4/0xe44 [scsi_mod] [C00000002F447EE0] [C00000000007B4E0] .kthread+0x128/0x178 [C00000002F447F90] [C000000000025E84] .kernel_thread+0x4c/0x68 Unable to handle kernel paging request for <7>PCI: Enabling device: (0002:41:01.1), cmd 143 data at address 0x000001b8 Faulting instruction address: 0xd0000000000698e4 sym1: <1010-66> rev 0x1 at pci 0002:41:01.1 irq 216 sym1: No NVRAM, ID 7, Fast-80, LVD, parity checking sym1: SCSI BUS has been reset. scsi2 : sym-2.2.2 cpu 0x0: Vector: 300 (Data Access) at [c00000002f447a30] pc: d0000000000698e4: .scsi_run_queue+0x2c/0x218 [scsi_mod] lr: d00000000006a904: .scsi_run_host_queues+0x28/0x5c [scsi_mod] sp: c00000002f447cb0 msr: 9000000000009032 dar: 1b8 dsisr: 40000000 current = 0xc0000000045fecd0 paca = 0xc00000000048ee80 pid = 1123, comm = scsi_eh_1 enter ? for help [c00000002f447d60] d00000000006a904 .scsi_run_host_queues+0x28/0x5c [scsi_mod] [c00000002f447df0] d000000000069054 .scsi_error_handler+0xdb4/0xe44 [scsi_mod] [c00000002f447ee0] c00000000007b4e0 .kthread+0x128/0x178 [c00000002f447f90] c000000000025e84 .kernel_thread+0x4c/0x68 Signed-off-by: Brian King <brking@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] scsi: Add allow_restart sysfs class attributeBrian King2006-06-281-0/+26
| | | | | | | | | | | | | | This is a resend of a patch I generated in response to an email sent by Ruben Faelens <parasietje@gmail.com>. His original email to linux-scsi requested a method in which he could spin down a scsi disk when not in use and have the kernel automatically spin it back up when an I/O was generated to the disk. The infrastructure to automatically spin a disk up has been in the scsi error handler for some time now, but it is not enabled by default. This patch adds an sd sysfs attribute which allows userspace to enable this behavior. Signed-off-by: Brian King <brking@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
* [SCSI] fc transport: bug fix: correct referencesJames Smart2006-06-271-6/+6
| | | | | | | | | | | | | | | | | | | Original post was incorrect as it didn't realize that we already had a self-referenc due to device_initialize(), and we were really only missing the put on our own reference. This was hidden by the other bug which had the midlayer reusing stargets after they were already free, which was doing too many puts on our rport. Updating FC transport for: - Add put in fc_rport_final_delete(), to release the rport. Prior, we were leaving the rport with a reference, thus the shost with references, etc. If the driver was unloaded, shosts and rports remained, along with work threads, etc - Fix fc_rport_create failure path - too many put's on parent - Add commenting to easily track ref taking.

* [SCSI] fc transport: resolve scan vs delete deadlocksJames Smart2006-06-271-13/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a prior posting to linux-scsi on the fc transport and workq deadlocks, we noted a second error that did not have a patch: http://marc.theaimsgroup.com/?l=linux-scsi&m=114467847711383&w=2 - There's a deadlock where scsi_remove_target() has to sit behind scsi_scan_target() due to contention over the scan_lock(). Subsequently we posted a request for comments about the deadlock: http://marc.theaimsgroup.com/?l=linux-scsi&m=114469358829500&w=2 This posting resolves the second error. Here's what we now understand, and are implementing: If the lldd deletes the rport while a scan is active, the sdev's queue is blocked which stops the issuing of commands associated with the scan. At this point, the scan stalls, and does so with the shost->scan_mutex held. If, at this point, if any scan or delete request is made on the host, it will stall waiting for the scan_mutex. For the FC transport, we queue all delete work to a single workq. So, things worked fine when competing with the scan, as long as the target blocking the scan was the same target at the top of our delete workq, as the delete workq routine always unblocked just prior to requesting the delete. Unfortunately, if the top of our delete workq was for a different target, we deadlock. Additionally, if the target blocking scan returned, we were unblocking it in the scan workq routine, which really won't execute until the existing stalled scan workq completes (e.g. we're re-scheduling it while it is in the midst of its execution). This patch moves the unblock out of the workq routines and moves it to the context that is scheduling the work. This ensures that at some point, we will unblock the target that is blocking scan. Please note, however, that the deadlock condition may still occur while it waits for the transport to timeout an unblock on a target. Worst case, this is bounded by the transport dev_loss_tmo (default: 30 seconds). Finally, Michael Reed deserves the credit for the bulk of this patch, analysis, and it's testing. Thank you for your help. Note: The request for comments statements about the gross-ness of the scan_mutex still stand.

| | | | | | | | | | | | | | | | | | | This patch simplifies "good_bytes" computation in sd_rw_intr(). sd: "good_bytes" computation is always done in terms of the resolution of the device's medium, since after that it is the number of good bytes we pass around and other layers/contexts (as opposed ot sd) can translate that to their own resolution (block layer:512). It also makes scsi_io_completion() processing more straightforward, eliminating the 3rd argument to the function. It also fixes a couple of bugs like not checking return value, using "break" instead of "return;", etc. I've been running with this patch for some time now on a test (do-it-all) system.

| | | | | | | | | | | | | | | | | | Even with the latest fixes aic79xx still occasionally triggers the BUG_ON in slave_destroy. Rather than trying to figure out the various levels of interaction here I've decided to remove the callback altogether. The primary reason for the slave_alloc / slave_destroy is to keep an index of pointers to the sdevs associated with a given target. However, by changing the arguments to the affected functions slightly it's possible to avoid the use of that index entirely. The only performance penalty we'll incur is in writing the information for /proc/scsi/XXX, as we'll have to recurse over all available sdevs to find the correct ones. But I doubt that reading from /proc is in any way time-critical. Signed-off-by: Hannes Reinecke <hare@suse.de> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| * | [PATCH] libata: implement per-dev EH action mask eh_info->dev_action[]Tejun Heo2006-06-221-16/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the only per-dev EH action is REVALIDATE. EH used to exploit ehi->dev to do selective revalidation on a ATA bus. However, this is a bit hacky and makes it impossible to request selective revalidation from outside of EH or add another per-dev EH action. This patch adds per-dev EH action mask eh_info->dev_action[] and update EH to use this field for REVALIDATE. Note that per-dev actions can still be specified at port-level and it has the same effect of specifying the action for all devices on the port.
