Fixes a race between zfcp_fsf_req_dismiss_all and zfcp_qdio_reqid_check. During adapter shutdown it occurred that a request was cleaned up twice. First during its normal completion. Second when dismiss_all was called. The fix is to serialize access to fsf request list between zfcp_fsf_req_dismiss_all and zfcp_qdio_reqid_check and delete a fsf request from the list if its completion is triggered. (Additionally a rwlock was replaced by a spinlock and fsf_req_cleanup was eliminated.)

From: Maxim Shchetynin <maxim@de.ibm.com> Fixes a bug in zfcp_send_els_handler.

A problem exists todayin the sg driver that if an SG_IO request is outstanding to a device when it is removed from the system. The system may oops if that command completes later in time. 1. sg_remove gets called 2. sg_remove calls sg_finish_req_req on all pending requests This removes the Sg_request's from the headrp list in the Sg_fd 3. The sleeping SG_IO ioctl is woken. It does nothing and returns. 4. The caller closes the fd, which invokes sg_release 5. sg_release calls sg_remove_sfp. It finds no outstanding commands since the headrp list is empty, so it calls __sg_remove_sfp, which frees the sfp. 6. Now when sg_cmd_done gets called, sg uses upper_private_data in the Scsi_Request, which should point to the srp, which has been freed, so it points to freed memory. 7. sg then dereferences the srp pointer to get the sfp, and we oops. The fix is to NULL out the upper_private_data field in this path, which sg_cmd_done already checks for, which will prevent the oops from occurring. cpu 0x1: Vector: 300 (Data Access) at [c00000000fff7aa0] pc: d0000000002bbea8: .sg_cmd_done+0x70/0x394 [sg] lr: d000000000073304: .scsi_finish_command+0x10c/0x130 [scsi_mod] sp: c00000000fff7d20 msr: 8000000000009032 dar: 2f70726f63202f78 dsisr: 40000000 current = 0xc0000000024589b0 paca = 0xc0000000003da800 pid = 7, comm = events/1 [c00000000fff7dc0] d000000000073304 .scsi_finish_command+0x10c/0x130 [scsi_mod] [c00000000fff7e50] d00000000007317c .scsi_softirq+0x140/0x168 [scsi_mod] [c00000000fff7ef0] c0000000000634dc .__do_softirq+0xa0/0x17c [c00000000fff7f90] c000000000018430 .call_do_softirq+0x14/0x24 [c00000000ed472e0] c0000000000142e0 .do_softirq+0x74/0x9c [c00000000ed47370] c000000000013c9c .do_IRQ+0xe8/0x100 [c00000000ed473f0] c00000000000ae34 HardwareInterrupt_entry+0x8/0x54 c00000000003df28 .smp_call_function+0 x100/0x1d0 [c00000000ed47780] c0000000000ba99c .invalidate_bh_lrus+0x30/0x70 [c00000000ed47810] c0000000000b91a0 .invalidate_bdev+0x18/0x3c [c00000000ed478a0] c0000000000da7b8 .__invalidate_device+0x70/0x94 [c00000000ed47930] c0000000001d40bc .invalidate_partition+0x4c/0x7c [c00000000ed479c0] c00000000010a944 .del_gendisk+0x48/0x15c [c00000000ed47a50] d00000000003d55c .sd_remove+0x34/0xe4 [sd_mod] [c00000000ed47ae0] c0000000001c5d30 .device_release_driver+0x90/0xb4 [c00000000ed47b70] c0000000001c6130 .bus_remove_device+0xb0/0x12c [c00000000ed47c00] c0000000001c4378 .device_del+0x120/0x198 [c00000000ed47ca0] d00000000007dcdc .scsi_remove_device+0xb4/0x194 [scsi_mod] [c00000000ed47d30] d0000000000a5864 .ipr_worker_thread+0x1d4/0x27c [ipr] [c00000000ed47dd0] c0000000000734c4 .worker_thread+0x238/0x2f4 [c00000000ed47ee0] c0000000000796c0 .kthread+0xcc/0x11c [c00000000ed47f90] c000000000018ad0 .kernel_thread+0x4c/0x6c Signed-off-by: NBrian King <brking@us.ibm.com> Signed-off-by: NJames Bottomley <James.Bottomley@SteelEye.com>

From: Marcello Maggioni <hayarms@gmail.com> Problem: Some drives (NEC 3500, TDK 1616N, Mad-dog MD-16XDVD9, RICOH MP5163DA, Memorex DVD9 drive and IO-DATA's too for sure), if a CD/DVD is inserted into the tray when the system is booted and if before the OS bootup the BIOS checked for the presence of a bootable CD/DVD into the drive, during the IDE probe phase the drive may result busy and remain so for the next 25/30 seconds . This cause the drive to be skipped during the booting phase and not begin usable until the next reboot (if the reboot goes well and the drive doesn't timeout again). Solution: Rising the timeout time from 10 seconds to 35 seconds (during these 35 seconds every drive should wake up for sure according to the tests I've done).

a) TYPE_SDAD renamed to TYPE_RBC and taken to scsi.h b) in sbp2.c remapping of TYPE_RPB to TYPE_DISK turned off c) relevant places in midlayer and sd.c taught to accept TYPE_RBC d) sd.c::sd_read_cache_type() looks into page 6 when dealing with TYPE_RBC - these guys have writeback cache flag there and are not guaranteed to have page 8 at all. e) sd_read_cache_type() got an extra sanity check - it checks that it got the page it asked for before using its contents. And screams if mismatch had happened. Rationale: there are broken devices out there that are "helpful" enough to go for "I don't have a page you've asked for, here, have another one". For example, PL3507 had been caught doing just that... f) sbp2 sets sdev->use_10_for_rw and sdev->use_10_for_ms instead of bothering to remap READ6/WRITE6/MOD_SENSE, so most of the conversions in there are gone now. Incidentally, I wonder if USB storage devices that have no mode page 8 are simply RBC ones. I haven't touched that, but it might be interesting to check...

When testing ATAPI PIO data transfer on the ppc64 platform, __atapi_pio_bytes() got zero when sg_dma_len() is used. I checked the <asm-ppc64/scatterlish.h>, the struct scatterlist is defined as: struct scatterlist { struct page *page; unsigned int offset; unsigned int length; /* For TCE support */ u32 dma_address; u32 dma_length; }; #define sg_dma_address(sg) ((sg)->dma_address) #define sg_dma_len(sg) ((sg)->dma_length) So, if the scatterlist is not DMA mapped, sg_dma_len() will return zero on ppc64. The same problem should occur on the x86-64 platform. On the i386 platform, sg_dma_len() returns sg->length, that's why the problem does not occur on an i386. Changes: - Use sg->length if the scatterlist is not DMA mapped (yet). Signed-off-by: NAlbert Lee <albertcc@tw.ibm.com>
