media: rc: read out of bounds if bpf reports high protocol number

2018-07-30T12:19:53+00:00

The repeat period is read from a static array. If a keydown event is reported from bpf with a high protocol number, we read out of bounds. This is unlikely to end up with a reasonable repeat period at the best of times, in which case no timely key up event is generated. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: bpf: ensure bpf program is freed on detach

2018-07-26T12:39:18+00:00

Currently we are leaking bpf programs when they are detached from the lirc device; the refcount never reaches zero. Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab

media: rc: be less noisy when driver misbehaves

2018-06-27T14:03:45+00:00

Since commit 48231f289e52 ("media: rc: drivers should produce alternate pulse and space timing events"), on meson-ir we are regularly producing errors. Reduce to warning level and only warn once to avoid flooding the log. A proper fix for meson-ir is going to be too large for v4.18.

bpf: fix attach type BPF_LIRC_MODE2 dependency wrt CONFIG_CGROUP_BPF

2018-06-26T09:28:38+00:00

If the kernel is compiled with CONFIG_CGROUP_BPF not enabled, it is not possible to attach, detach or query IR BPF programs to /dev/lircN devices, making them impossible to use. For embedded devices, it should be possible to use IR decoding without cgroups or CONFIG_CGROUP_BPF enabled. This change requires some refactoring, since bpf_prog_{attach,detach,query} functions are now always compiled, but their code paths for cgroups need moving out. Rather than a #ifdef CONFIG_CGROUP_BPF in kernel/bpf/syscall.c, moving them to kernel/bpf/cgroup.c and kernel/bpf/sockmap.c does not require #ifdefs since that is already conditionally compiled.

2018-06-12T00:49:09+00:00

Pull ARM SoC platform updates from Olof Johansson: "Here are the main updates for SoC support (besides DT additions) for ARM 32- and 64-bit platforms. The branch also contains defconfig updates to turn on drivers and options as needed on the various platforms. The largest parts of the delta are from cleanups moving platform data and board file setup of TI platforms to ti-sysc bus drivers. There are also some sweeping changes of eeprom and nand setup on Davinci, i.MX and other platforms. Samsung is removing support for Exynos5440, which was an oddball SoC that hasn't been seen much use in designs. Renesas is adding support for new SoCs (R-Car E3, RZ/G1C and RZ/N1D). Linus Walleij is also removing support for ux500 (Sony Ericsson) U8540/9540 SoCs that never made it to significant mass production and products" * tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (133 commits) MAINTAINERS: add NXP linux team maillist as i.MX reviewer ARM: stm32: Don't select DMA unconditionally on STM32MP157C arm64: defconfig: Enable PCIe on msm8996 and db820c ARM: pxa3xx: enable external wakeup pins ARM: pxa: stargate2: use device properties for at24 eeprom arm64: defconfig: Enable HISILICON_LPC arm64: defconfig: enable drivers for Poplar support arm64: defconfig: Enable UFS on msm8996 ARM: berlin: switch to SPDX license identifier arm: berlin: remove non-necessary flush_cache_all() ARM: berlin: extend BG2CD Kconfig entry OMAP: CLK: CLKSRC: Add suspend resume hooks ARM: AM43XX: Add functions to save/restore am43xx control registers ASoC: ams_delta: use GPIO lookup table ARM: OMAP1: ams-delta: add GPIO lookup tables bus: ti-sysc: Fix optional clocks array access ARM: OMAP2+: Make sure LOGICRETSTATE bits are not cleared ARM: OMAP2+: prm44xx: Inroduce cpu_pm notifiers for context save/restore ARM: OMAP2+: prm44xx: Introduce context save/restore for am43 PRCM IO ARM: OMAP2+: powerdomain: Introduce cpu_pm notifiers for context save/restore ...

Pull media updates from Mauro Carvalho Chehab: - remove of atomisp driver from staging, as nobody would have time to dedicate huge efforts to fix all the problems there. Also, we have a feeling that the driver may not even run the way it is. - move Zoran driver to staging, in order to be either fixed to use VB2 and the proper media kAPIs or to be removed - remove videobuf-dvb driver, with is unused for a while - some V4L2 documentation fixes/improvements - new sensor drivers: imx258 and ov7251 - a new driver was added to allow using I2C transparent drivers - several improvements at the ddbridge driver - several improvements at the ISDB pt1 driver, making it more coherent with the DVB framework - added a new platform driver for MIPI CSI-2 RX: cadence - now, all media drivers can be compiled on x86 with COMPILE_TEST - almost all media drivers now build on non-x86 architectures with COMPILE_TEST - lots of other random stuff: cleanups, support for new board models, bug fixes, etc * tag 'media/v4.18-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (464 commits) media: omap2: fix compile-testing with FB_OMAP2=m media: media/radio/Kconfig: add back RADIO_ISA media: v4l2-ioctl.c: fix missing unlock in __video_do_ioctl() media: pxa_camera: ignore -ENOIOCTLCMD from v4l2_subdev_call for s_power media: arch: sh: migor: Fix TW9910 PDN gpio media: staging: tegra-vde: Reset VDE regardless of memory client resetting failure media: marvel-ccic: mmp: select VIDEOBUF2_VMALLOC/DMA_CONTIG media: marvel-ccic: allow ccic and mmp drivers to coexist media: uvcvideo: Prevent setting unavailable flags media: ddbridge: conditionally enable fast TS for stv0910-equipped bridges media: dvb-frontends/stv0910: make TS speed configurable media: ddbridge/mci: add identifiers to function definition arguments media: ddbridge/mci: protect against out-of-bounds array access in stop() media: rc: ensure input/lirc device can be opened after register media: rc: nuvoton: Keep device enabled during reg init media: rc: nuvoton: Keep track of users on CIR enable/disable media: rc: nuvoton: Tweak the interrupt enabling dance media: uvcvideo: Support realtek's UVC 1.5 device media: uvcvideo: Fix driver reference counting media: gspca_zc3xx: Enable short exposure times for OV7648 ...

media: rc: introduce BPF_PROG_LIRC_MODE2

2018-05-30T10:38:40+00:00

Add support for BPF_PROG_LIRC_MODE2. This type of BPF program can call rc_keydown() to reported decoded IR scancodes, or rc_repeat() to report that the last key should be repeated. The bpf program can be attached to using the bpf(BPF_PROG_ATTACH) syscall; the target_fd must be the /dev/lircN device.

media: rc: ensure input/lirc device can be opened after register

2018-05-28T21:40:33+00:00

Since commit cb84343fced1 ("media: lirc: do not call close() or open() on unregistered devices") rc_open() will return -ENODEV if rcdev->registered is false. Ensure this is set before we register the input device and the lirc device, else we have a short window where the neither the lirc or input device can be opened.

Doing writes when the device is disabled seems to be a NOOP. For CIR device, we should enable it, initialize it, and then disable it until it's opened. CIR_WAKE should always be enabled. Signed-off-by: Michał Winiarski Cc: Jarod Wilson Signed-off-by: Sean Young Signed-off-by: Mauro Carvalho Chehab
