Each driver calling scsi_ioctl() gets an equivalent compat_ioctl() handler that implements the same commands by calling scsi_compat_ioctl(). The scsi_cmd_ioctl() and scsi_cmd_blk_ioctl() functions are compatible at this point, so any driver that calls those can do so for both native and compat mode, with the argument passed through compat_ptr(). With this, we can remove the entries from fs/compat_ioctl.c. The new code is larger, but should be easier to maintain and keep updated with newly added commands. Reviewed-by:

Rather than relying on fs/compat_ioctl.c, this adds support for a compat_ioctl() callback in the ide-floppy driver directly, which lets it translate the scsi commands. Reviewed-by:

bsg_ioctl() calls into scsi_cmd_ioctl() for a couple of generic commands and relies on fs/compat_ioctl.c to handle it correctly in compat mode. Adding a private compat_ioctl() handler avoids that round-trip and lets us get rid of the generic emulation once this is done. Note that bsg implements an SG_IO command that is different from the other drivers and does not need emulation. Reviewed-by:

In order to move the compat handling for SCSI ioctl commands out of fs/compat_ioctl.c into the individual drivers, we need a helper function first to match the native ioctl handler called by sd, sr, st, etc. Reviewed-by:

Various block drivers implement the CDROMMULTISESSION, CDROM_GET_CAPABILITY, and CDROMEJECT ioctl commands, relying on the block layer to handle compat_ioctl mode for them. Move this into the drivers directly as a preparation for simplifying the block layer later. When only integer arguments or no arguments are passed, the same handler can be used for .ioctl and .compat_ioctl, and when only pointer arguments are passed, the newly added blkdev_compat_ptr_ioctl can be used.

This is the only ioctl command that does not have a proper compat handler. Making the normal implementation do the right thing is actually very simply, so just do that by using an in_compat_syscall() check to avoid the special case in the pkcdvd driver. Reviewed-by:

There is only one implementation of this ioctl, so move the handling out of the common block layer code into the place where it's actually needed. It also gets called indirectly through pktcdvd, which needs to be aware of this change. As I noticed, the old implementation of the compat handler failed to convert the structure on the way out, so the updated fields never got written back to user space. This is either not important, or it has never worked and should be fixed now. Reviewed-by:

These drivers implement the HDIO_GET_IDENTITY and CDROMVOLREAD ioctl commands, which are compatible between 32-bit and 64-bit user space and traditionally handled by compat_blkdev_driver_ioctl(). As a prerequisite to removing that function, make both drivers use blkdev_compat_ptr_ioctl() as their .compat_ioctl callback. Reviewed-by:

A lot of block drivers need only a trivial .compat_ioctl callback. Add a helper function that can be set as the callback pointer to only convert the argument using the compat_ptr() conversion and otherwise assume all input and output data is compatible, or handled using in_compat_syscall() checks. This mirrors the compat_ptr_ioctl() helper function used in character devices. Reviewed-by:

In the v5.4 merge window, a cleanup patch from Al Viro conflicted with my rework of the compat handling for sg.c read(). Linus Torvalds did a correct merge but pointed out that the resulting code is still unsatisfactory. I later noticed that the sg_new_read() function still gets the compat mode wrong, when the 'count' argument is large enough to pass a compat_sg_io_hdr object, but not a nativ sg_io_hdr. To address both of these, move the definition of compat_sg_io_hdr into a scsi/sg.h to make it visible to sg.c and rewrite the logic for reading req_pack_id as well as the size check to a simpler version that gets the expected results.

When support for !MMU was added, the declaration of __asm_copy_to_user() & __asm_copy_from_user() were #ifdefed out hence their EXPORT_SYMBOL() give an error message like: .../riscv_ksyms.c:13:15: error: '__asm_copy_to_user' undeclared here .../riscv_ksyms.c:14:15: error: '__asm_copy_from_user' undeclared here Since these symbols are not defined with !MMU it's wrong to export them. Same for __clear_user() (even though this one is also declared in include/asm-generic/uaccess.h and thus doesn't give an error message). Fix this by doing the EXPORT_SYMBOL() directly where these symbols are defined: inside lib/uaccess.S itself. Fixes: 6bd33e1e ("riscv: fix compile failure with EXPORT_SYMBOL() & !MMU") Reported-by:

The downstream implementation of ahci_brcm.c did contain clock management recovery, but until recently, did that outside of the libahci_platform helpers and this was unintentionally stripped out while forward porting the patch upstream. Add the missing clock management during recovery and sleep for 10 milliseconds per the design team recommendations to ensure the SATA PHY controller and AFE have been fully quiesced.

Set AHCI_HFLAG_DELAY_ENGINE for the BCM7425 AHCI controller thus making it conforming to the 'strict' AHCI implementation which this controller is based on. This solves long link establishment with specific hard drives (e.g.: Seagate ST1000VM002-9ZL1 SC12) that would otherwise have to complete the error recovery handling before finally establishing a succesful SATA link at the desired speed.

The AHCI resources management within ahci_brcm.c is a little convoluted, largely because it historically had a dedicated clock that was managed within this file in the downstream tree. Once brough upstream though, the clock was left to be managed by libahci_platform.c which is entirely appropriate. This patch series ensures that the AHCI resources are fetched and enabled before any register access is done, thus avoiding bus errors on platforms which clock gate the controller by default. As a result we need to re-arrange the suspend() and resume() functions in order to avoid accessing registers after the clocks have been turned off respectively before the clocks have been turned on. Finally, we can refactor brcm_ahci_get_portmask() in order to fetch the number of ports from hpriv->mmio which is now accessible without jumping through hoops like we used to do. The commit pointed in the Fixes tag is both old and new enough not to require major headaches for backporting of this patch.

ata_qc_complete_multiple() is called with a mask of the still active tags. mv_sata doesn't have this information directly and instead calculates the still active tags from the started tags (ap->qc_active) and the finished tags as (ap->qc_active ^ done_mask) Since 28361c40 the hw_tag and tag are no longer the same and the equation is no longer valid. In ata_exec_internal_sg() ap->qc_active is initialized as 1ULL << ATA_TAG_INTERNAL, but in hardware tag 0 is started and this will be in done_mask on completion. ap->qc_active ^ done_mask becomes 0x100000000 ^ 0x1 = 0x100000001 and thus tag 0 used as the internal tag will never be reported as completed. This is fixed by introducing ata_qc_get_active() which returns the active hardware tags and calling it where appropriate. This is tested on mv_sata, but sata_fsl and sata_nv suffer from the same problem. There is another case in sata_nv that most likely needs fixing as well, but this looks a little different, so I wasn't confident enough to change that.

The rseq.h UAPI now documents that the rseq_cs field must be cleared before reclaiming memory that contains the targeted struct rseq_cs, but also that the rseq_cs field must be cleared before reclaiming memory of the code pointed to by the rseq_cs start_ip and post_commit_offset fields. While we can expect that use of dlclose(3) will typically unmap both struct rseq_cs and its associated code at once, nothing would theoretically prevent a JIT from reclaiming the code without reclaiming the struct rseq_cs, which would erroneously allow the kernel to consider new code which is not a rseq critical section as a rseq critical section following a code reclaim.
