2023-03-10scsi: aacraid: Allocate cmd_priv with scsicmdKees Cook
commit 7ab734fc759828707dae22fe48b1eb4dcf70beea upstream. The aac_priv() helper assumes that the private cmd area immediately follows struct scsi_cmnd. Allocate this space as part of scsicmd, else there is a risk of heap overflow. Seen with GCC 13: ../drivers/scsi/aacraid/aachba.c: In function 'aac_probe_container': ../drivers/scsi/aacraid/aachba.c:841:26: warning: array subscript 16 is outside array bounds of 'void[392]' [-Warray-bounds=] 841 | status = cmd_priv->status; | ^~ In file included from ../include/linux/resource_ext.h:11, from ../include/linux/pci.h:40, from ../drivers/scsi/aacraid/aachba.c:22: In function 'kmalloc', inlined from 'kzalloc' at ../include/linux/slab.h:720:9, inlined from 'aac_probe_container' at ../drivers/scsi/aacraid/aachba.c:821:30: ../include/linux/slab.h:580:24: note: at offset 392 into object of size 392 allocated by 'kmalloc_trace' 580 | return kmalloc_trace( | ^~~~~~~~~~~~~~ 581 | kmalloc_caches[kmalloc_type(flags)][index], | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 582 | flags, size); | ~~~~~~~~~~~~ Fixes: 76a3451b64c6 ("scsi: aacraid: Move the SCSI pointer to private command data") Link: https://lore.kernel.org/r/20230128000409.never.976-kees@kernel.org Cc: Bart Van Assche <bvanassche@acm.org> Cc: Hannes Reinecke <hare@suse.de> Cc: Himanshu Madhani <himanshu.madhani@oracle.com> Cc: Adaptec OEM Raid Solutions <aacraid@microsemi.com> Cc: "James E.J.

2021-10-16scsi: aacraid: Call scsi_done() directlyBart Van Assche
The aacraid driver invokes scmd->scsi_done(scmd) for two types of SCSI commands: - SCSI commands initialized by the SCSI mid-layer. - SCSI commands initialized by aac_probe_container(). The processing sequence for SCSI commands allocated by aac_probe_container() is as follows: aac_probe_container() -> _aac_probe_container(scmd, aac_probe_container_callback1) -> scmd->SCp.ptr = aac_probe_container_callback1 -> aac_fib_send(..., _aac_probe_container1, scmd) -> fibptr->callback = _aac_probe_container1 -> fibptr->callback_data = scmd fibptr->callback(scmd) -> _aac_probe_container1(scmd, fibptr) [ ... ] -> _aac_probe_container2(scmd, fibptr) -> Call scmd->SCp.ptr == aac_probe_container_callback1 -> scmd->device = NULL; The processing sequence for SCSI commands allocated by the SCSI mid-layer if _aac_probe_container() is called is as follows: aac_queuecommand() -> aac_scsi_cmd() -> _aac_probe_container(scmd, aac_probe_container_callback2) -> scmd->SCp.ptr = aac_probe_container_callback2 -> aac_fib_send(..., _aac_probe_container1, scmd) fibptr->callback(scmd) -> _aac_probe_container1(scmd, fibptr) [ ... ] -> _aac_probe_container2(scmd, fibptr) -> Call scmd->SCp.ptr == aac_probe_container_callback2 Preserve the existing call sequences by calling scsi_done() for commands submitted by the mid-layer or aac_probe_container_scsi_done() for commands submitted by aac_probe_container().

2021-05-10scsi: aacraid: Replace one-element array with flexible-array memberGustavo A. R. Silva
There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2]. Refactor the code according to the use of a flexible-array member in struct aac_raw_io2 instead of one-element array, and use the struct_size() helper. Also, this helps with the ongoing efforts to enable -Warray-bounds by fixing the following warnings: drivers/scsi/aacraid/aachba.c: In function ‘aac_build_sgraw2’: drivers/scsi/aacraid/aachba.c:3970:18: warning: array subscript 1 is above array bounds of ‘struct sge_ieee1212[1]’ [-Warray-bounds] 3970 | if (rio2->sge[j].length % (i*PAGE_SIZE)) { | ~~~~~~~~~^~~ drivers/scsi/aacraid/aachba.c:3974:27: warning: array subscript 1 is above array bounds of ‘struct sge_ieee1212[1]’ [-Warray-bounds] 3974 | nseg_new += (rio2->sge[j].length / (i*PAGE_SIZE)); | ~~~~~~~~~^~~ drivers/scsi/aacraid/aachba.c:4011:28: warning: array subscript 1 is above array bounds of ‘struct sge_ieee1212[1]’ [-Warray-bounds] 4011 | for (j = 0; j < rio2->sge[i].length / (pages * PAGE_SIZE); ++j) { | ~~~~~~~~~^~~ drivers/scsi/aacraid/aachba.c:4012:24: warning: array subscript 1 is above array bounds of ‘struct sge_ieee1212[1]’ [-Warray-bounds] 4012 | addr_low = rio2->sge[i].addrLow + j * pages * PAGE_SIZE; | ~~~~~~~~~^~~ drivers/scsi/aacraid/aachba.c:4014:33: warning: array subscript 1 is above array bounds of ‘struct sge_ieee1212[1]’ [-Warray-bounds] 4014 | sge[pos].addrHigh = rio2->sge[i].addrHigh; | ~~~~~~~~~^~~ drivers/scsi/aacraid/aachba.c:4015:28: warning: array subscript 1 is above array bounds of ‘struct sge_ieee1212[1]’ [-Warray-bounds] 4015 | if (addr_low < rio2->sge[i].addrLow) | ~~~~~~~~~^~~ [1] https://en.wikipedia.org/wiki/Flexible_array_member [2] https://www.kernel.org/doc/html/v5.9/process/deprecated.html#zero-length-and-one-element-arrays Link: https://github.com/KSPP/linux/issues/79 Link: https://github.com/KSPP/linux/issues/109 Link: https://lore.kernel.org/lkml/60414244.ur4%2FkI+fBF1ohKZs%25lkp@intel.com/ Link: https://lore.kernel.org/r/20210421185611.GA105224@embeddedor Signed-off-by: Gustavo A.

2021-01-22scsi: aacraid: Avoid setting message byte on completionHannes Reinecke
The aacraid controller is a RAID controller and the driver will never see any SCSI messages. Plus it's quite pointless to set the message byte if the host byte is already set, as the latter takes precedence during error recovery. Drop the message byte values for the final result.

2020-11-25scsi: aacraid: Use generic power managementVaibhav Gupta
Drivers should do only device-specific jobs. But in general, drivers using legacy PCI PM framework for .suspend()/.resume() have to manage many PCI PM-related tasks themselves which can be done by PCI Core itself. This brings extra load on the driver and it directly calls PCI helper functions to handle them. Switch to the new generic framework by updating function signatures and define a "struct dev_pm_ops" variable to bind PM callbacks. Also, remove unnecessary calls to the PCI Helper functions along with the legacy .suspend & .resume bindings.

2020-11-25scsi: aacraid: Drop pci_enable_wake() from .resumeVaibhav Gupta
The driver calls pci_enable_wake(...., false) in aac_resume(), and there is no corresponding pci_enable_wake(...., true) in aac_suspend(). Either it should do enable-wake the device in .suspend() or should not invoke pci_enable_wake() at all. Concluding that this is a bug and PCI core calls pci_enable_wake(pci_dev, PCI_D0, false) during resume, drop it from aac_resume().

2020-11-04scsi: aacraid: Improve compat_ioctl handlersArnd Bergmann
The use of compat_alloc_user_space() can be easily replaced by handling compat arguments in the regular handler, and this will make it work for big-endian kernels as well, which at the moment get an invalid indirect pointer argument. Calling aac_ioctl() instead of aac_compat_do_ioctl() means the compat and native code paths behave the same way again, which they stopped when the adapter health check was added only in the native function.

2020-07-07PCI: Use 'pci_channel_state_t' instead of 'enum pci_channel_state'Luc Van Oostenryck
The method struct pci_error_handlers.error_detected() is defined and documented as taking an 'enum pci_channel_state' for the second argument, but most drivers use 'pci_channel_state_t' instead. This 'pci_channel_state_t' is not a typedef for the enum but a typedef for a bitwise type in order to have better/stricter typechecking. Consolidate everything by using 'pci_channel_state_t' in the method's definition, in the related helpers and in the drivers. Enforce use of 'pci_channel_state_t' by replacing 'enum pci_channel_state' with an anonymous 'enum'. Note: Currently, from a typechecking point of view this patch changes nothing because only the constants defined by the enum are bitwise, not the enum itself (sparse doesn't have the notion of 'bitwise enum'). This may change in some not too far future, hence the patch.
