* sunrpc: move pc_count out of struct svc_procinfoChristoph Hellwig2017-05-1510-7/+28
| | | | | | | | | | pc_count is the only writeable memeber of struct svc_procinfo, which is a good candidate to be const-ified as it contains function pointers. This patch moves it into out out struct svc_procinfo, and into a separate writable array that is pointed to by struct svc_version. Signed-off-by: Christoph Hellwig <hch@lst.de>
* nfsd4: properly type op_func callbacksChristoph Hellwig2017-05-153-173/+209
| | | | | | | | | | Pass union nfsd4_op_u to the op_func callbacks instead of using unsafe function pointer casts. It also adds two missing structures to struct nfsd4_op.u to facilitate this. Signed-off-by: Christoph Hellwig <hch@lst.de>
* nfsd4: remove nfsd4op_rsizeChristoph Hellwig2017-05-151-55/+54
| | | | | | | Except for a lot of unnecessary casts this typedef only has one user, so remove the casts and expand it in struct nfsd4_operation. Signed-off-by: Christoph Hellwig <hch@lst.de>
* nfsd4: properly type op_get_currentstateid callbacksChristoph Hellwig2017-05-153-35/+50

* nfsd4: properly type op_set_currentstateid callbacksChristoph Hellwig2017-05-154-19/+27

* sunrpc: properly type pc_encode callbacksChristoph Hellwig2017-05-1521-170/+185
| | | | | | | | | Drop the resp argument as it can trivially be derived from the rqstp argument. With that all functions now have the same prototype, and we can remove the unsafe casting to kxdrproc_t.

* sunrpc: properly type pc_func callbacksChristoph Hellwig2017-05-1511-227/+328
| | | | | | | | | Drop the argp and resp arguments as they can trivially be derived from the rqstp argument. With that all functions now have the same prototype, and we can remove the unsafe casting to svc_procfunc as well as the svc_procfunc typedef itself. Signed-off-by: Christoph Hellwig <hch@lst.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The userspace xboxdrv driver [0] contains some USB IDs unknown to the kernel driver. I have created a simple script [1] to extract the missing devices and add them to xpad. A quick google search confirmed that all the new devices called Fightstick/pad are Arcade-type devices [2] where the MAP_TRIGGERS_TO_BUTTONS option should apply. There are some similar devices in the existing device table where this flag is not set, but I did refrain from changing those.

The problem is that ubi_scan_fastmap() moves the fastmap blocks from the scan_ai (allocated in scan_fast()) to the ai allocated in ubi_attach(). This results in two problems: - When the scan_ai is freed, aebs which were allocated from its slab cache are still in use. - When the other ai is being destroyed in destroy_ai(), the arguments to kmem_cache_free() call are incorrect since aebs on its ->fastmap list were allocated with a slab cache from a differnt ai. Fix this by making a copy of the aebs in ubi_scan_fastmap() instead of moving them. ============================================================================= BUG ubi_aeb_slab_cache (Not tainted): Objects remaining in ubi_aeb_slab_cache on __kmem_cache_shutdown() ----------------------------------------------------------------------------- INFO: Slab 0xbfd2da3c objects=17 used=1 fp=0xb33d7748 flags=0x40000080 CPU: 1 PID: 118 Comm: ubiattach Tainted: G B 4.9.15 #3 [<80111910>] (unwind_backtrace) from [<8010d498>] (show_stack+0x18/0x1c) [<8010d498>] (show_stack) from [<804a3274>] (dump_stack+0xb4/0xe0) [<804a3274>] (dump_stack) from [<8026c47c>] (slab_err+0x78/0x88) [<8026c47c>] (slab_err) from [<802735bc>] (__kmem_cache_shutdown+0x180/0x3e0) [<802735bc>] (__kmem_cache_shutdown) from [<8024e13c>] (shutdown_cache+0x1c/0x60) [<8024e13c>] (shutdown_cache) from [<8024ed64>] (kmem_cache_destroy+0x19c/0x20c) [<8024ed64>] (kmem_cache_destroy) from [<8057cc14>] (destroy_ai+0x1dc/0x1e8) [<8057cc14>] (destroy_ai) from [<8057f04c>] (ubi_attach+0x3f4/0x450) [<8057f04c>] (ubi_attach) from [<8056fe70>] (ubi_attach_mtd_dev+0x60c/0xff8) [<8056fe70>] (ubi_attach_mtd_dev) from [<80571d78>] (ctrl_cdev_ioctl+0x110/0x2b8) [<80571d78>] (ctrl_cdev_ioctl) from [<8029c77c>] (do_vfs_ioctl+0xac/0xa00) [<8029c77c>] (do_vfs_ioctl) from [<8029d10c>] (SyS_ioctl+0x3c/0x64) [<8029d10c>] (SyS_ioctl) from [<80108860>] (ret_fast_syscall+0x0/0x1c) INFO: Object 0xb33d7e88 @offset=3720 INFO: Allocated in scan_peb+0x608/0x81c age=72 cpu=1 pid=118 kmem_cache_alloc+0x3b0/0x43c scan_peb+0x608/0x81c ubi_attach+0x124/0x450 ubi_attach_mtd_dev+0x60c/0xff8 ctrl_cdev_ioctl+0x110/0x2b8 do_vfs_ioctl+0xac/0xa00 SyS_ioctl+0x3c/0x64 ret_fast_syscall+0x0/0x1c kmem_cache_destroy ubi_aeb_slab_cache: Slab cache still has objects CPU: 1 PID: 118 Comm: ubiattach Tainted: G B 4.9.15 #3 [<80111910>] (unwind_backtrace) from [<8010d498>] (show_stack+0x18/0x1c) [<8010d498>] (show_stack) from [<804a3274>] (dump_stack+0xb4/0xe0) [<804a3274>] (dump_stack) from [<8024ed80>] (kmem_cache_destroy+0x1b8/0x20c) [<8024ed80>] (kmem_cache_destroy) from [<8057cc14>] (destroy_ai+0x1dc/0x1e8) [<8057cc14>] (destroy_ai) from [<8057f04c>] (ubi_attach+0x3f4/0x450) [<8057f04c>] (ubi_attach) from [<8056fe70>] (ubi_attach_mtd_dev+0x60c/0xff8) [<8056fe70>] (ubi_attach_mtd_dev) from [<80571d78>] (ctrl_cdev_ioctl+0x110/0x2b8) [<80571d78>] (ctrl_cdev_ioctl) from [<8029c77c>] (do_vfs_ioctl+0xac/0xa00) [<8029c77c>] (do_vfs_ioctl) from [<8029d10c>] (SyS_ioctl+0x3c/0x64) [<8029d10c>] (SyS_ioctl) from [<80108860>] (ret_fast_syscall+0x0/0x1c) cache_from_obj: Wrong slab cache. ubi_aeb_slab_cache but object is from ubi_aeb_slab_cache ------------[ cut here ]------------ WARNING: CPU: 1 PID: 118 at mm/slab.h:354 kmem_cache_free+0x39c/0x450 Modules linked in: CPU: 1 PID: 118 Comm: ubiattach Tainted: G B 4.9.15 #3 [<80111910>] (unwind_backtrace) from [<8010d498>] (show_stack+0x18/0x1c) [<8010d498>] (show_stack) from [<804a3274>] (dump_stack+0xb4/0xe0) [<804a3274>] (dump_stack) from [<80120e40>] (__warn+0xf4/0x10c) [<80120e40>] (__warn) from [<80120f20>] (warn_slowpath_null+0x28/0x30) [<80120f20>] (warn_slowpath_null) from [<80271fe0>] (kmem_cache_free+0x39c/0x450) [<80271fe0>] (kmem_cache_free) from [<8057cb88>] (destroy_ai+0x150/0x1e8) [<8057cb88>] (destroy_ai) from [<8057ef1c>] (ubi_attach+0x2c4/0x450) [<8057ef1c>] (ubi_attach) from [<8056fe70>] (ubi_attach_mtd_dev+0x60c/0xff8) [<8056fe70>] (ubi_attach_mtd_dev) from [<80571d78>] (ctrl_cdev_ioctl+0x110/0x2b8) [<80571d78>] (ctrl_cdev_ioctl) from [<8029c77c>] (do_vfs_ioctl+0xac/0xa00) [<8029c77c>] (do_vfs_ioctl) from [<8029d10c>] (SyS_ioctl+0x3c/0x64) [<8029d10c>] (SyS_ioctl) from [<80108860>] (ret_fast_syscall+0x0/0x1c) ---[ end trace 2bd8396277fd0a0b ]--- ============================================================================= BUG ubi_aeb_slab_cache (Tainted: G B W ): page slab pointer corrupt. ----------------------------------------------------------------------------- INFO: Allocated in scan_peb+0x608/0x81c age=104 cpu=1 pid=118 kmem_cache_alloc+0x3b0/0x43c scan_peb+0x608/0x81c ubi_attach+0x124/0x450 ubi_attach_mtd_dev+0x60c/0xff8 ctrl_cdev_ioctl+0x110/0x2b8 do_vfs_ioctl+0xac/0xa00 SyS_ioctl+0x3c/0x64 ret_fast_syscall+0x0/0x1c INFO: Slab 0xbfd2da3c objects=17 used=1 fp=0xb33d7748 flags=0x40000081 INFO: Object 0xb33d7e88 @offset=3720 fp=0xb33d7da0 Redzone b33d7e80: cc cc cc cc cc cc cc cc ........
