I have been working with Steffen on zFCP for quite a while now and we decided adding me as a co-maintainer might be a good thing. Acked-by:

Scsi_cmnd is an unsuitable argument for eh_device_reset_handler(), eh_target_reset_handler(), and eh_host_reset_handler() which do not have the scope of one single SCSI command. These callbacks tend to use fc_block_scsi_eh() requiring scsi_cmnd. In order to start decoupling above eh callbacks from scsi_cmnd, introduce a new variant of the function called fc_block_rport() taking an fc_rport as argument. Refactor the old fc_block_scsi_eh() to simply delegate to fc_block_rport(). Signed-off-by:

It's better to use the DRIVER_ATTR_RW() and DRIVER_ATTR_RO() macros to explicitly show that this is a read/write or read/only sysfs file. So convert the remaining SCSI drivers that use the old style to use the newer macros. Bonus is that this removes some checkpatch.pl warnings :) This is part of a series to drop DRIVER_ATTR() from the tree entirely. Cc: "James E.J. Bottomley" <jejb@linux.vnet.ibm.com> Cc: "Martin K.

We print a 256 byte event string into a buffer that is only 161 bytes long, this is clearly wrong: drivers/scsi/gdth_proc.c: In function 'gdth_show_info': drivers/scsi/gdth.c:3660:41: error: '%s' directive writing up to 255 bytes into a region of size between 141 and 150 [-Werror=format-overflow=] sprintf(buffer,"Adapter %d: %s\n", ^~ /git/arm-soc/drivers/scsi/gdth.c:3660:13: note: 'sprintf' output between 13 and 277 bytes into a destination of size 161 sprintf(buffer,"Adapter %d: %s\n", ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ dvr->eu.async.ionode,dvr->event_string); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ gcc calculates that the worst case buffer size would be 277 bytes, so we can use that.

The MSI interrupt name can require 11 bytes in addition to the device name, for a total of 23 bytes: drivers/scsi/fnic/fnic_isr.c: In function 'fnic_request_intr': drivers/scsi/fnic/fnic_isr.c:192:4: error: '-fcs-rq' directive writing 7 bytes into a region of size between 5 and 16 [-Werror=format-overflow=] "%.11s-fcs-rq", fnic->name); drivers/scsi/fnic/fnic_isr.c:206:3: note: 'sprintf' output between 12 and 23 bytes into a destination of size 16 sprintf(fnic->msix[FNIC_MSIX_ERR_NOTIFY].devname, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "%.11s-err-notify", fnic->name); This extends the buffer to fit any possible value.

gcc notices that we would overflow the buffer for the inquiry of the product name if we have too many adapters: drivers/scsi/gdth.c: In function 'gdth_next': drivers/scsi/gdth.c:2357:29: warning: 'sprintf' may write a terminating nul past the end of the destination [-Wformat-overflow=] sprintf(inq.product,"Host Drive #%02d",t); ^~~~~~~~~~~~~~~~~~~ drivers/scsi/gdth.c:2357:9: note: 'sprintf' output between 16 and 17 bytes into a destination of size 16 sprintf(inq.product,"Host Drive #%02d",t); This won't happen in practice, so just use snprintf to truncate the string.

We print the driver name into one string and then add and ID and copy it into a second string of the same length, at which point gcc complains about a possible overflow: drivers/scsi/mpt3sas/mpt3sas_scsih.c: In function '_scsih_probe': drivers/scsi/mpt3sas/mpt3sas_scsih.c:8884:21: error: '_cm' directive writing 3 bytes into a region of size between 1 and 32 [-Werror=format-overflow=] printf(ioc->name, "%s_cm%d", ioc->driver_name, ioc->id); ^~~~~~~~~ drivers/scsi/mpt3sas/mpt3sas_scsih.c:8884:21: note: directive argument in the range [0, 255] drivers/scsi/mpt3sas/mpt3sas_scsih.c:8884:2: note: 'sprintf' output between 5 and 38 bytes into a destination of size 32 sprintf(ioc->name, "%s_cm%d", ioc->driver_name, ioc->id); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Making the first string shorter is sufficient to avoid the warning here, as we know it can only contain either "mpt2sas" or "mpt3sas".

Limit PDMA send to 512 B to avoid data corruption on DTC3181E. The corruption is always the same: one byte missing at the beginning of a 128 B block. It happens only with slow Quantum LPS 240 drive, not with faster IBM DORS-32160. It's not clear what causes this. Documentation for the DTC436 chip has not been made available. Signed-off-by:

The polling loops in pread() and pwrite() can easily become infinite loops and hang the machine. Merge the IRQ check into host buffer wait loop and add polling limit. Also place a limit on polling for 53C80 registers accessibility. [Use NCR5380_poll_politely2() for register polling. Rely on polling for gated IRQ rather than polling for phase error, like the algorithm in the 53c400 datasheet. Move DTC436 workarounds into a separate patch. Factor-out common code as wait_for_53c80_access(). Rework the residual calculations. -- F.T.] Signed-off-by:

When an IRQ arrives during PDMA transfer, pread() and pwrite() return without waiting for the 53C80 registers to be ready and this ends up messing up the chip state. This was observed with SONY CDU-55S which is slow enough to disconnect during 4096-byte reads. IRQ during PDMA is not an error so don't return -1. Instead, store the remaining byte count for use by NCR5380_dma_residual(). [Poll for the BASR_END_DMA_TRANSFER condition rather than remove the error message -- F.T.] Signed-off-by:

generic_NCR5380_dma_xfer_len() incorrectly uses cmd->transfersize which causes rescan-scsi-bus and CD-ROM access to hang the system. Use cmd->SCp.this_residual instead, like other NCR5380 drivers. Signed-off-by:

When sending a reset fib we shouldn't rely on the scsi command, but rather set the TMF status in the map_info->reset_state variable. That allows us to send a TMF independent on a scsi command. Signed-off-by:
