2021-10-15drm/nouveau/fifo: Reinstate the correct engine bit programmingMarek Vasut1-1/+1
Commit 64f7c698bea9 ("drm/nouveau/fifo: add engine_id hook") replaced fifo/chang84.c g84_fifo_chan_engine() call with an indirect call of fifo/g84.c g84_fifo_engine_id(). The G84_FIFO_ENGN_* values returned from the later g84_fifo_engine_id() are incremented by 1 compared to the previous g84_fifo_chan_engine() return values. This is fine either way for most of the code, except this one line where an engine bit programmed into the hardware is derived from the return value. Decrement the return value accordingly, otherwise the wrong engine bit is programmed into the hardware and that leads to the following failure: nouveau 0000:01:00.0: gr: 00000030 [ILLEGAL_MTHD ILLEGAL_CLASS] ch 1 [003fbce000 DRM] subc 3 class 0000 mthd 085c data 00000420 On the following hardware: lspci -s 01:00.0 01:00.0 VGA compatible controller: NVIDIA Corporation GT216GLM [Quadro FX 880M] (rev a2) lspci -ns 01:00.0 01:00.0 0300: 10de:0a3c (rev a2) Fixes: 64f7c698bea9 ("drm/nouveau/fifo: add engine_id hook") Signed-off-by: Marek Vasut <[email protected]> Cc: <[email protected]> # 5.12+ Cc: Ben Skeggs <[email protected]> Cc: Karol Herbst <[email protected]> Cc: Lyude Paul <[email protected]> Reviewed-by: Karol Herbst <[email protected]> Reviewed-by: Ben Skeggs <[email protected]> Signed-off-by: Karol Herbst <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected] Signed-off-by: Dave Airlie <[email protected]>
2021-10-15drm/hyperv: Fix double mouse pointersDexuan Cui3-1/+55
Hyper-V supports a hardware cursor feature. It is not used by Linux VM, but the Hyper-V host still draws a point as an extra mouse pointer, which is unwanted, especially when Xorg is running. The hyperv_fb driver uses synthvid_send_ptr() to hide the unwanted pointer. When the hyperv_drm driver was developed, the function synthvid_send_ptr() was not copied from the hyperv_fb driver. Fix the issue by adding the function into hyperv_drm.

2021-10-15drm/edid: In connector_bad_edid() cap num_of_ext by num_blocks readDouglas Anderson1-3/+12
In commit e11f5bd8228f ("drm: Add support for DP 1.4 Compliance edid corruption test") the function connector_bad_edid() started assuming that the memory for the EDID passed to it was big enough to hold `edid[0x7e] + 1` blocks of data (1 extra for the base block). It completely ignored the fact that the function was passed `num_blocks` which indicated how much memory had been allocated for the EDID. Let's fix this by adding a bounds check. This is important for handling the case where there's an error in the first block of the EDID. In that case we will call connector_bad_edid() without having re-allocated memory based on `edid[0x7e]`.

2021-10-14libperf tests: Fix test_stat_cpuShunsuke Nakamura2-6/+6
The `cpu` argument of perf_evsel__read() must specify the cpu index. perf_cpu_map__for_each_cpu() is for iterating the cpu number (not index) and is thus not appropriate for use with perf_evsel__read(). So, if there is an offline CPU, the cpu number specified in the argument may point out of range because the cpu number and the cpu index are different. Fix test_stat_cpu().

2021-10-14icmp: fix icmp_ext_echo_iio parsing in icmp_build_probeXin Long1-12/+11
In icmp_build_probe(), the icmp_ext_echo_iio parsing should be done step by step and skb_header_pointer() return value should always be checked, this patch fixes 3 places in there: - On case ICMP_EXT_ECHO_CTYPE_NAME, it should only copy ident.name from skb by skb_header_pointer(), its len is ident_len. Besides, the return value of skb_header_pointer() should always be checked. - On case ICMP_EXT_ECHO_CTYPE_INDEX, move ident_len check ahead of skb_header_pointer(), and also do the return value check for skb_header_pointer(). - On case ICMP_EXT_ECHO_CTYPE_ADDR, before accessing iio->ident.addr. ctype3_hdr.addrlen, skb_header_pointer() should be called first, then check its return value and ident_len. On subcases ICMP_AFI_IP and ICMP_AFI_IP6, also do check for ident. addr.ctype3_hdr.addrlen and skb_header_pointer()'s return value. On subcase ICMP_AFI_IP, the len for skb_header_pointer() should be "sizeof(iio->extobj_hdr) + sizeof(iio->ident.addr.ctype3_hdr) + sizeof(struct in_addr)" or "ident_len". v1->v2: - To make it more clear, call skb_header_pointer() once only for iio->indent's parsing as Jakub Suggested. v2->v3: - The extobj_hdr.length check against sizeof(_iio) should be done before calling skb_header_pointer(), as Eric noticed.

2021-10-14sctp: account stream padding length for reconf chunkEiichi Tsukata1-1/+1
sctp_make_strreset_req() makes repeated calls to sctp_addto_chunk() which will automatically account for padding on each call. inreq and outreq are already 4 bytes aligned, but the payload is not and doing SCTP_PAD4(a + b) (which _sctp_make_chunk() did implicitly here) is different from SCTP_PAD4(a) + SCTP_PAD4(b) and not enough. It led to possible attempt to use more buffer than it was allocated and triggered a BUG_ON.

2021-10-14mlxsw: thermal: Fix out-of-bounds memory accessesIdo Schimmel1-47/+5
Currently, mlxsw allows cooling states to be set above the maximum cooling state supported by the driver: # cat /sys/class/thermal/thermal_zone2/cdev0/type mlxsw_fan # cat /sys/class/thermal/thermal_zone2/cdev0/max_state 10 # echo 18 > /sys/class/thermal/thermal_zone2/cdev0/cur_state # echo $? 0 This results in out-of-bounds memory accesses when thermal state transition statistics are enabled (CONFIG_THERMAL_STATISTICS=y), as the transition table is accessed with a too large index (state) [1]. According to the thermal maintainer, it is the responsibility of the driver to reject such operations [2]. Therefore, return an error when the state to be set exceeds the maximum cooling state supported by the driver. To avoid dead code, as suggested by the thermal maintainer [3], partially revert commit a421ce088ac8 ("mlxsw: core: Extend cooling device with cooling levels") that tried to interpret these invalid cooling states (above the maximum) in a special way.

2021-10-14spi-mux: Fix false-positive lockdep splatsUwe Kleine-König2-6/+13
io_mutex is taken by spi_setup() and spi-mux's .setup() callback calls spi_setup() which results in a nested lock of io_mutex. add_lock is taken by spi_add_device(). The device_add() call in there can result in calling spi-mux's .probe() callback which registers its own spi controller which in turn results in spi_add_device() being called again. To fix this initialize the controller's locks already in spi_alloc_controller() to give spi_mux_probe() a chance to set the lockdep subclass.

2021-10-14spi: Fix deadlock when adding SPI controllers on SPI busesMark Brown2-11/+9
Currently we have a global spi_add_lock which we take when adding new devices so that we can check that we're not trying to reuse a chip select that's already controlled. This means that if the SPI device is itself a SPI controller and triggers the instantiation of further SPI devices we trigger a deadlock as we try to register and instantiate those devices while in the process of doing so for the parent controller and hence already holding the global spi_add_lock. Since we only care about concurrency within a single SPI bus move the lock to be per controller, avoiding the deadlock. This can be easily triggered in the case of spi-mux.

2021-10-13Revert "net: procfs: add seq_puts() statement for dev_mcast"Vladimir Oltean1-13/+11
This reverts commit ec18e8455484370d633a718c6456ddbf6eceef21. It turns out that there are user space programs which got broken by that change. One example is the "ifstat" program shipped by Debian: https://packages.debian.org/source/bullseye/ifstat which, confusingly enough, seems to not have anything in common with the much more familiar (at least to me) ifstat program from iproute2: https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/tree/misc/ifstat.c root@debian:~# ifstat ifstat: /proc/net/dev: unsupported format.

Even if we fix this ancient and very "lightly" maintained program to parse the text output of /proc/net/dev in a more sensible way, this story seems bound to repeat again with other programs, and modifying them all could cause more trouble than it's worth. On the other hand, the reverted patch had no other reason than an aesthetic one, so reverting it is the simplest way out. I don't know what other distributions would be affected; the fact that Debian doesn't ship the iproute2 version of the program (a different code base altogether, which uses netlink and not /proc/net/dev) is surprising in itself.

2021-10-13tracing: Fix event probe removal from dynamic eventsSteven Rostedt (VMware)1-3/+51
When an event probe is to be removed via the API that created it via the dynamic events, an -ENOENT error is returned. This is because the removal of the event probe does not expect to see the event system and name that the event probe is attached to, even though that's part of the API to create it. As the removal of probes is to use the same API as they are created. In fact, the removal is not consistent with the kprobes and uprobes removal. Fix that by allowing various ways to remove the eprobe.

2021-10-13nvmem: Fix shift-out-of-bound (UBSAN) with byte size cellsStephen Boyd1-1/+2
If a cell has 'nbits' equal to a multiple of BITS_PER_BYTE the logic *p &= GENMASK((cell->nbits%BITS_PER_BYTE) - 1, 0); will become undefined behavior because nbits modulo BITS_PER_BYTE is 0, and we subtract one from that making a large number that is then shifted more than the number of bits that fit into an unsigned long. UBSAN reports this problem: UBSAN: shift-out-of-bounds in drivers/nvmem/core.c:1386:8 shift exponent 64 is too large for 64-bit type 'unsigned long' CPU: 6 PID: 7 Comm: kworker/u16:0 Not tainted 5.15.0-rc3+ #9 Hardware name: Google Lazor (rev3+) with KB Backlight (DT) Workqueue: events_unbound deferred_probe_work_func Call trace: dump_backtrace+0x0/0x170 show_stack+0x24/0x30 dump_stack_lvl+0x64/0x7c dump_stack+0x18/0x38 ubsan_epilogue+0x10/0x54 __ubsan_handle_shift_out_of_bounds+0x180/0x194 __nvmem_cell_read+0x1ec/0x21c nvmem_cell_read+0x58/0x94 nvmem_cell_read_variable_common+0x4c/0xb0 nvmem_cell_read_variable_le_u32+0x40/0x100 a6xx_gpu_init+0x170/0x2f4 adreno_bind+0x174/0x284 component_bind_all+0xf0/0x264 msm_drm_bind+0x1d8/0x7a0 try_to_bring_up_master+0x164/0x1ac __component_add+0xbc/0x13c component_add+0x20/0x2c dp_display_probe+0x340/0x384 platform_probe+0xc0/0x100 really_probe+0x110/0x304 __driver_probe_device+0xb8/0x120 driver_probe_device+0x4c/0xfc __device_attach_driver+0xb0/0x128 bus_for_each_drv+0x90/0xdc __device_attach+0xc8/0x174 device_initial_probe+0x20/0x2c bus_probe_device+0x40/0xa4 deferred_probe_work_func+0x7c/0xb8 process_one_work+0x128/0x21c process_scheduled_works+0x40/0x54 worker_thread+0x1ec/0x2a8 kthread+0x138/0x158 ret_from_fork+0x10/0x20 Fix it by making sure there are any bits to mask out.
