2007-11-03[SCSI] ibmvscsi: Prevent IO during partner loginRobert Jennings
By setting the request_limit in send_srp_login to 1 we allowed login requests to be sent to the server adapter. If this was not an initial login, but was a login after a disconnect with the server, other I/O requests could attempt to be processed before the login occured. These I/O requests would fail, sometimes resulting in filesystems getting marked read-only. To address this we can set the request_limit to 0 while doing the login and add an exception where login requests, along with task management events, are always passed to the server. There is a case where the request_limit had already reached 0 would result in all events being sent rather than returning SCSI_MLQUEUE_HOST_BUSY; this has also been fixed by this patch.

2007-11-02[SG] Get rid of __sg_mark_end()Jens Axboe
sg_mark_end() overwrites the page_link information, but all users want __sg_mark_end() behaviour where we just set the end bit. That is the most natural way to use the sg list, since you'll fill it in and then mark the end point. So change sg_mark_end() to only set the termination bit. Add a sg_magic debug check as well, and clear a chain pointer if it is set. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2007-10-29fix abuses of ptrdiff_tAl Viro
Use of ptrdiff_t in places like - if (!access_ok(VERIFY_WRITE, u_tmp->rx_buf, u_tmp->len)) + if (!access_ok(VERIFY_WRITE, (u8 __user *) + (ptrdiff_t) u_tmp->rx_buf, + u_tmp->len)) is wrong; for one thing, it's a bad C (it's what uintptr_t is for; in general we are not even promised that ptrdiff_t is large enough to hold a pointer, just enough to hold a difference between two pointers within the same object). For another, it confuses the fsck out of sparse. Use unsigned long or uintptr_t instead. There are several places misusing ptrdiff_t; fixed.

2007-10-23[SCSI] qla2xxx: Correct residual-count handling discrepancies during ↵Andrew Vasquez
UNDERRUN handling. For recent ISPs, software during CS_UNDERRUN handling must determine if the two residuals, firmware-calculated and FCP_RSP, are different to recognize if a frame has been dropped. Update the driver to catch this condition, and clear the SS_RESIDUAL_UNDER and lscsi_status bits. This logic is consistent with what earlier firmwares did by explicitly cracking open the FCP_RSP statuses and clearing SS_RESIDUAL_UNDER.

2007-10-23[SCSI] qla2xxx: Make driver (mostly) legacy I/O port free.Andrew Vasquez
Recent ISPs need only the single MMIO BAR to manipulate HW registers. Unfortunately, ISP21xx, ISP22xx, ISP23xx, and ISP63xx type cards still require the I/O mapped region to manipulate the FLASH via the two HW flash-registers (flash_address and flash_data).

2007-10-23[SCSI] qla2xxx: Handle unaligned sector writes during NVRAM/VPD updates.Andrew Vasquez
Since both NVRAM and VPD regions of the flash reside on unaligned sector boundaries, during update, the driver must perform a read-modify-write operation to the composite NVRAM/VPD region.

2007-10-23[SCSI] sym53c8xx: Remove pci_dev pointer from sym_shcbMatthew Wilcox
This structure is accessed by the device; the fewer Linux things in it, the better.

2007-10-23[SCSI] sym53c8xx: Simplify DAC DMA handlingMatthew Wilcox
By introducing the use_dac(), set_dac() and DMA_DAC_MASK macros, we can eliminate a lot of ifdefs from the code. We now rely on the compiler to optimise away a few things that we'd formerly relied on the preprocessor to do. This makes sym_setup_bus_dma_mask() small enough to inline into its only caller.

2007-10-23[SCSI] sym53c8xx: Stop overriding scsi_doneMatthew Wilcox
Instead of telling the reset routine that the command completed from sym_eh_done, do it from sym_xpt_done.
