scsi: advansys: Prefer struct_size() over open-coded arithmetic As noted in the "Deprecated Interfaces, Language Features, Attributes, and Conventions" documentation [1], size calculations (especially multiplication) should not be performed in memory allocator (or similar) function arguments due to the risk of them overflowing. This could lead to values wrapping around and a smaller allocation being made than the caller was expecting. Using those allocations could lead to linear overflows of heap memory and other misbehaviors. Use the struct_size() helper to do the arithmetic instead of the argument "size + count * size" in the kzalloc() function. This code was detected with the help of Coccinelle and audited and fixed manually.

scsi: advansys: Replace zero-length array with flexible-array member The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle. [1] https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html [2] https://github.com/KSPP/linux/issues/21 [3] commit 76497732932f ("cxgb3/l2t: Fix undefined behaviour") Link: https://lore.kernel.org/r/20200213000211.GA23171@embeddedor.com Reviewed-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Gustavo A.

scsi: advansys: use sg helper to iterate over scatterlist Unlike the legacy I/O path, scsi-mq preallocates a large array to hold the scatterlist for each request. This static allocation can consume substantial amounts of memory on modern controllers which support a large number of concurrently outstanding requests. To facilitate a switch to a smaller static allocation combined with a dynamic allocation for requests that need it, we need to make sure all SCSI drivers handle chained scatterlists correctly. Convert remaining drivers that directly dereference the scatterlist array to using the iterator functions. [mkp: clarified commit message] Reviewed-by: Ewan D.

scsi: don't set tagging state from scsi_adjust_queue_depth Remove the tagged argument from scsi_adjust_queue_depth, and just let it handle the queue depth. For most drivers those two are fairly separate, given that most modern drivers don't care about the SCSI "tagged" status of a command at all, and many old drivers allow queuing of multiple untagged commands in the driver. Instead we start out with the ->simple_tags flag set before calling ->slave_configure, which is how all drivers actually looking at ->simple_tags except for one worke anyway. The one other case looks broken, but I've kept the behavior as-is for now. Except for that we only change ->simple_tags from the ->change_queue_type, and when rejecting a tag message in a single driver, so keeping this churn out of scsi_adjust_queue_depth is a clear win. Now that the usage of scsi_adjust_queue_depth is more obvious we can also remove all the trivial instances in ->slave_alloc or ->slave_configure that just set it to the cmd_per_lun default.

SCSI host lock push-down Move the mid-layer's ->queuecommand() invocation from being locked with the host lock to being unlocked to facilitate speeding up the critical path for drivers who don't need this lock taken anyway. The patch below presents a simple SCSI host lock push-down as an equivalent transformation. No locking or other behavior should change with this patch. All existing bugs and locking orders are preserved. Additionally, add one parameter to queuecommand, struct Scsi_Host * and remove one parameter from queuecommand, void (*done)(struct scsi_cmnd *) Scsi_Host* is a convenient pointer that most host drivers need anyway, and 'done' is redundant to struct scsi_cmnd->scsi_done. Minimal code disturbance was attempted with this change. Most drivers needed only two one-line modifications for their host lock push-down.

[SCSI] advansys: fix regression with request_firmware change On newer kernels users of advansys module are reporting system hang when trying to load it without firmware files present. After looking closely at description on https://qa.mandriva.com/show_bug.cgi?id=53220, I think this is related to commit "[SCSI] advansys: use request_firmware". The problem is that after switch to request_firmware, asc_dvc->err_code isn't being set when firmware files aren't found or loading fails. err_code is used by the driver to judge if there was a fatal error or not, as can be seen for example on advansys_board_found, which will only return -ENODEV when err_code is set. Because err_code isn't being set when request_firmware fails, this is a change of behaviour of the code before request_firmware addition, making it continue to load and it fails later as the firmware wasn't really loaded.

advansys fix on ISA-less configs The code if (shost->dma_channel != NO_ISA_DMA) free_dma(shost->dma_channel); in there is triggerable only if we have CONFIG_ISA (we only set ->dma_channel to something other than NO_ISA_DMA under #ifdef CONFIG_ISA). OTOH, free_dma() is not guaranteed to be there in absense of CONFIG_ISA. IOW, driver runs into undefined symbols on PCI-but-not-ISA configs (e.g. on frv) and it's a false positive. Fix: put the entire if () under #ifdef CONFIG_ISA; behaviour doesn't change and dependency on free_dma() disappears for !CONFIG_ISA.

[SCSI] advansys: fix overrun_buf aligned bug struct asc_dvc_var needs overrun buffer to be placed on an 8 byte boundary. advansys defines struct asc_dvc_var: struct asc_dvc_var { ... uchar overrun_buf[ASC_OVERRUN_BSIZE] __aligned(8); The problem is that struct asc_dvc_var is placed on shost->hostdata. So if the hostdata is not on an 8 byte boundary, the advansys crashes. The hostdata is placed on a sizeof(unsigned long) boundary so the 8 byte boundary is not garanteed with x86_32. With 2.6.23 and 2.6.24, the hostdata is on an 8 byte boundary by chance, but with the current git, it's not. This patch removes overrun_buf static array and use kzalloc.

[SCSI] advansys: Sort out debug macros Replace ASC_DBG{,1,2,3,4,5} with a single variadic macro ASC_DBG. As suggested by Jeff Garzik, include DRV_NAME and __FUNCTION__ in the output. Change all callers to no longer include the function name in the string. Enabling ADVANSYS_DEBUG to test this feature shows a lot of other problems that need to be fixed: - Reorder asc_prt_* functions now that their prototypes have been removed. - There is no longer a struct device in ASC_DVC_CFG/ADV_DVC_CFG, and it wasn't necessarily a PCI device to begin with. Print the bus_id from asc_board->dev instead. - isr_callback no longer exists. - ASC_DBG_PRT_SCSI_CMND isn't being used, so delete asc_prt_scsi_cmnd too. - A missing semicolon Signed-off-by: Matthew Wilcox <willy@linux.intel.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

[SCSI] advansys: Sort out irq number mess The interrupt number was being stored in 4-5 different places, each with its own type, rules and usage. Fix this by keeping an unsigned int in the struct asc_board, and filling it in from the bus probe functions (since it's different for each of the four bus types). In order to do this, we have to allocate the Scsi_Host in the bus probe functions too. Then we can return an error from advansys_board_found, which requires a little rearranging of code (and removing of the err_code variable). Move the Wide Board flag setting into the PCI bus probe function. Split the AscGetChipIRQ function into three functions (one for each bus type that needs it) and add some commentary to explain what's going on. Also get rid of the AscSetChipIRQ function as we only ever set the interrupt number to the same value it already had.

Use BUG() where it fits better than BUG_ON(). Also fix a fencepost error in advansys_proc_info(). - Replace DvcSleepMilliSecond with mdelay. Despite its name using 'sleep', the implementation was a delay. I've marked some places with XXX where we should probably be using msleep instead. They need to be audited to be sure we can sleep in that context. - Replace DvcDelayMicroSecond with udelay. - Replace DvcDelayNanoSecond with udelay too. All callers were multiples of 1000. - Remove DvcEnterCritical and DvcLeaveCritical. These functions are no-ops, and as the comments said, the spinlock protects the critical sections.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

[SCSI] add global timeout to the scsi mid-layer There are certain rogue devices (and the aic7xxx driver) that return BUSY or QUEUE_FULL forever. This code will apply a global timeout (of the total number of retries times the per command timer) to a given command. If it is exceeded, the command is completed regardless of its state. The patch also removes the unused field in the command: timeout and timeout_total. This solves the problem of detecting an endless loop in the mid-layer because of BUSY/QUEUE_FULL bouncing, but will not recover the device. In the aic7xxx case, the driver can be recovered by sending a bus reset, so possibly this should be tied into the error handler? Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
