staging: vchiq: Reformat Kconfig help textsThe lines in the VCHIQ Kconfig help texts are too long, which makesit hard to read the menuconfig.

f3e93e3e - staging: vc04_services: Re-add dependency on HAS_DMA to BCM2835_VCHIQ

Mon, 25 Apr 2022 12:18:25 +0000

staging: vc04_services: Re-add dependency on HAS_DMA to BCM2835_VCHIQThanks to stubs for the NO_DMA=y case, drivers that use the DMA API canbe compile-tested on systems that do not support DMA. Hence thedependency of BCM2835_VCHIQ on HAS_DMA was dropped to increase compilecoverage.Unfortunately compilers became smarter, leading to new failures.E.g. for a CONFIG_SUN3=y allmodconfig kernel with gcc 9.4.0: drivers/staging/vc04_services/interface/vchiq_arm/vchiq_2835_arm.c: In function ‘free_pagelist’: arch/m68k/include/asm/string.h:72:25: warning: argument 2 null where non-null expected [-Wnonnull] 72 | #define memcpy(d, s, n) __builtin_memcpy(d, s, n) | ^~~~~~~~~~~~~~~~~~~~~~~~~ drivers/staging/vc04_services/interface/vchiq_arm/vchiq_2835_arm.c:614:4: note: in expansion of macro ‘memcpy’ 614 | memcpy((char *)kmap(pages[0]) + | ^~~~~~ arch/m68k/include/asm/string.h:72:25: note: in a call to built-in function ‘__builtin_memcpy’ 72 | #define memcpy(d, s, n) __builtin_memcpy(d, s, n) | ^~~~~~~~~~~~~~~~~~~~~~~~~ drivers/staging/vc04_services/interface/vchiq_arm/vchiq_2835_arm.c:614:4: note: in expansion of macro ‘memcpy’ 614 | memcpy((char *)kmap(pages[0]) + | ^~~~~~This happens because the compiler can trace back the source pointer to aallocation by dma_alloc_attrs(), which always returns NULL if NO_DMA=y.Avoid this reinstating the dependency of the BCM2835_VCHIQ symbol onHAS_DMA, and by restricting the selection of BCM2835_VCHIQ.Signed-off-by: Geert Uytterhoeven Link: https://lore.kernel.org/r/da55bd87eebf1a969dc8ccd807843319833f6c40.1650888813.git.geert@linux-m68k.orgSigned-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/staging/vc04_services/Kconfig

Code was present tohandle the case where a CLOSE is sent immediately after an OPEN, i.e.before the OPENACK has been received, but this was incorrectly beingused when an OPEN from a client using port 0 was rejected.(In the observed failure, the host was attempting to use the VCSMservice, which isn't present in the 'cutdown' firmware. The failurewas intermittent because sometimes the keepalive service wouldgrab port 0.)This case can be distinguished because the client's remoteport willstill be VCHIQ_PORT_FREE, and the srvstate will be OPENING.

This is doneto keep this patch as small as possible.Also make available on ARCH_BCM2835.Based on work by Lubomir Rintel.Signed-off-by: Noralf Trønnes vchiq: Change logging level for inbound datavchiq_arm: Two cacheing fixes1) Make fragment size vary with cache line sizeWithout 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 isensured by having the loader apply a new DT parameter -cache-line-size. The existence of this parameter guarantees that thekernel is capable, and the parameter will only be modified from thesafe default if the loader is capable.2) Flush/invalidate vmalloc'd memory, and invalidate after readsvchiq: fix NULL pointer dereference when closing driverThe 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: 60080093sp : 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 attemptto push any items onto it.
