staging: vchiq_arm: move state dump to debugfs Besides the IOCTL interface the VCHIQ character device also provides a state dump of the whole VCHIQ driver via read. Moving the state dump function to debugfs has a lot advantages: - following changes on state dump doesn't break userspace ABI - debug doesn't depend on VCHIQ_CDEV - dump code simplifies a lot and reduce the chance of buffer overflows Signed-off-by: Stefan Wahren <wahrenst@gmx.net> Tested-by: "Ricardo B.

With these patches, calls to vchiq_close_service and vchiq_remove_service won't return until any associated callbacks have been delivered to the callback thread. VCHIQ: Add per-service tracing The new service option VCHIQ_SERVICE_OPTION_TRACE is a boolean that toggles tracing for the specified service. This commit also introduces vchi_service_set_option and the associated option VCHI_SERVICE_OPTION_TRACE. vchiq: Make the synchronous-CLOSE logic more tolerant vchiq: Move logging control into debugfs vchiq: Take care of a corner case tickled by VCSM Closing a connection that isn't fully open requires care, since one side does not know the other side's port number. Code was present to handle the case where a CLOSE is sent immediately after an OPEN, i.e. before the OPENACK has been received, but this was incorrectly being used when an OPEN from a client using port 0 was rejected. (In the observed failure, the host was attempting to use the VCSM service, which isn't present in the 'cutdown' firmware. The failure was intermittent because sometimes the keepalive service would grab port 0.) This case can be distinguished because the client's remoteport will still be VCHIQ_PORT_FREE, and the srvstate will be OPENING. Either condition is sufficient to differentiate it from the special case described above. vchiq: Avoid high load when blocked and unkillable vchiq: Include SIGSTOP and SIGCONT in list of signals not-masked by vchiq to allow gdb to work vchiq_arm: Complete support for SYNCHRONOUS mode vchiq: Remove inline from suspend/resume vchiq: Allocation does not need to be atomic vchiq: Fix wrong condition check The log level is checked from within the log call.

Signed-off-by: Noralf Trønnes <noralf@tronnes.org> vchiq: Change logging level for inbound data vchiq_arm: Two cacheing fixes 1) Make fragment size vary with cache line size Without this patch, non-cache-line-aligned transfers may corrupt (or be corrupted by) adjacent data structures. Both ARM and VC need to be updated to enable this feature. This is ensured by having the loader apply a new DT parameter - cache-line-size. The existence of this parameter guarantees that the kernel is capable, and the parameter will only be modified from the safe default if the loader is capable. 2) Flush/invalidate vmalloc'd memory, and invalidate after reads vchiq: fix NULL pointer dereference when closing driver The following code run as root will cause a null pointer dereference oops: int fd = open("/dev/vc-cma", O_RDONLY); if (fd < 0) err(1, "open failed"); (void)close(fd); [ 1704.877721] Unable to handle kernel NULL pointer dereference at virtual address 00000000 [ 1704.877725] pgd = b899c000 [ 1704.877736] [00000000] *pgd=37fab831, *pte=00000000, *ppte=00000000 [ 1704.877748] Internal error: Oops: 817 [#1] PREEMPT SMP ARM [ 1704.877765] Modules linked in: evdev i2c_bcm2708 uio_pdrv_genirq uio [ 1704.877774] CPU: 2 PID: 3656 Comm: stress-ng-fstat Not tainted 3.19.1-12-generic-bcm2709 #12-Ubuntu [ 1704.877777] Hardware name: BCM2709 [ 1704.877783] task: b8ab9b00 ti: b7e68000 task.ti: b7e68000 [ 1704.877798] PC is at __down_interruptible+0x50/0xec [ 1704.877806] LR is at down_interruptible+0x5c/0x68 [ 1704.877813] pc : [<80630ee8>] lr : [<800704b0>] psr: 60080093 sp : b7e69e50 ip : b7e69e88 fp : b7e69e84 [ 1704.877817] r10: b88123c8 r9 : 00000010 r8 : 00000001 [ 1704.877822] r7 : b8ab9b00 r6 : 7fffffff r5 : 80a1cc34 r4 : 80a1cc34 [ 1704.877826] r3 : b7e69e50 r2 : 00000000 r1 : 00000000 r0 : 80a1cc34 [ 1704.877833] Flags: nZCv IRQs off FIQs on Mode SVC_32 ISA ARM Segment user [ 1704.877838] Control: 10c5387d Table: 3899c06a DAC: 00000015 [ 1704.877843] Process do-oops (pid: 3656, stack limit = 0xb7e68238) [ 1704.877848] Stack: (0xb7e69e50 to 0xb7e6a000) [ 1704.877856] 9e40: 80a1cc3c 00000000 00000010 b88123c8 [ 1704.877865] 9e60: b7e69e84 80a1cc34 fff9fee9 ffffffff b7e68000 00000009 b7e69ea4 b7e69e88 [ 1704.877874] 9e80: 800704b0 80630ea4 fff9fee9 60080013 80a1cc28 fff9fee9 b7e69edc b7e69ea8 [ 1704.877884] 9ea0: 8040f558 80070460 fff9fee9 ffffffff 00000000 00000000 00000009 80a1cb7c [ 1704.877893] 9ec0: 00000000 80a1cb7c 00000000 00000010 b7e69ef4 b7e69ee0 803e1ba4 8040f514 [ 1704.877902] 9ee0: 00000e48 80a1cb7c b7e69f14 b7e69ef8 803e1c9c 803e1b74 b88123c0 b92acb18 [ 1704.877911] 9f00: b8812790 b8d815d8 b7e69f24 b7e69f18 803e2250 803e1bc8 b7e69f5c b7e69f28 [ 1704.877921] 9f20: 80167bac 803e222c 00000000 00000000 b7e69f54 b8ab9ffc 00000000 8098c794 [ 1704.877930] 9f40: b8ab9b00 8000efc4 b7e68000 00000000 b7e69f6c b7e69f60 80167d6c 80167b28 [ 1704.877939] 9f60: b7e69f8c b7e69f70 80047d38 80167d60 b7e68000 b7e68010 8000efc4 b7e69fb0 [ 1704.877949] 9f80: b7e69fac b7e69f90 80012820 80047c84 01155490 011549a8 00000001 00000006 [ 1704.877957] 9fa0: 00000000 b7e69fb0 8000ee5c 80012790 00000000 353d8c0f 7efc4308 00000000 [ 1704.877966] 9fc0: 01155490 011549a8 00000001 00000006 00000000 00000000 76cf3ba0 00000003 [ 1704.877975] 9fe0: 00000000 7efc42e4 0002272f 76e2ed66 60080030 00000003 00000000 00000000 [ 1704.877998] [<80630ee8>] (__down_interruptible) from [<800704b0>] (down_interruptible+0x5c/0x68) [ 1704.878015] [<800704b0>] (down_interruptible) from [<8040f558>] (vchiu_queue_push+0x50/0xd8) [ 1704.878032] [<8040f558>] (vchiu_queue_push) from [<803e1ba4>] (send_worker_msg+0x3c/0x54) [ 1704.878045] [<803e1ba4>] (send_worker_msg) from [<803e1c9c>] (vc_cma_set_reserve+0xe0/0x1c4) [ 1704.878057] [<803e1c9c>] (vc_cma_set_reserve) from [<803e2250>] (vc_cma_release+0x30/0x38) [ 1704.878069] [<803e2250>] (vc_cma_release) from [<80167bac>] (__fput+0x90/0x1e0) [ 1704.878082] [<80167bac>] (__fput) from [<80167d6c>] (____fput+0x18/0x1c) [ 1704.878094] [<80167d6c>] (____fput) from [<80047d38>] (task_work_run+0xc0/0xf8) [ 1704.878109] [<80047d38>] (task_work_run) from [<80012820>] (do_work_pending+0x9c/0xc4) [ 1704.878123] [<80012820>] (do_work_pending) from [<8000ee5c>] (work_pending+0xc/0x20) [ 1704.878133] Code: e50b1034 e3a01000 e50b2030 e580300c (e5823000) ..the fix is to ensure that we have actually initialized the queue before we attempt to push any items onto it.
