gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs Pull vfs fix from Christian Brauner: "During the pipe nonblock rework the check for both O_NONBLOCK and IOCB_NOWAIT was dropped. Both checks need to be performed to ensure that files without O_NONBLOCK but IOCB_NOWAIT don't block when writing to or reading from a pipe. This just contains the fix adding the check for IOCB_NOWAIT back in" * tag 'vfs/v6.4-rc1/pipe' of gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs: pipe: check for IOCB_NOWAIT alongside O_NONBLOCK

git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux Pull RISC-V fix from Palmer Dabbelt: "Just a single fix this week for a build issue. That'd usually be a good sign, but we've started to get some reports of boot failures on some hardware/bootloader configurations. Nothing concrete yet, but I've got a funny feeling that's where much of the bug hunting is going right now. Nothing's reproducing on my end, though, and this fixes some pretty concrete issues so I figured there's no reason to delay it: - a fix to the linker script to avoid orpahaned sections in kernel/pi" * tag 'riscv-for-linus-6.4-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux: riscv: Fix orphan section warnings caused by kernel/pi

2023-05-12pipe: check for IOCB_NOWAIT alongside O_NONBLOCKJens Axboe1-2/+4
Pipe reads or writes need to enable nonblocking attempts, if either O_NONBLOCK is set on the file, or IOCB_NOWAIT is set in the iocb being passed in. The latter isn't currently true, ensure we check for both before waiting on data or space.

2023-05-12block/rnbd: replace REQ_OP_FLUSH with REQ_OP_WRITEGuoqing Jiang1-1/+1
Since flush bios are implemented as writes with no data and the preflush flag per Christoph's comment [1]. And we need to change it in rnbd accordingly. Otherwise, I got splatting when create fs from rnbd client.

2023-05-11fbdev: imsttfb: Fix use after free bug in imsttfb_probeZheng Wang1-7/+8
A use-after-free bug may occur if init_imstt invokes framebuffer_release and free the info ptr. The caller, imsttfb_probe didn't notice that and still keep the ptr as private data in pdev. If we remove the driver which will call imsttfb_remove to make cleanup, UAF happens. Fix it by return error code if bad case happens in init_imstt.

2023-05-11drm/i915: taint kernel when force probing unsupported devicesJani Nikula2-5/+13
For development and testing purposes, the i915.force_probe module parameter and DRM_I915_FORCE_PROBE kconfig option allow probing of devices that aren't supported by the driver. The i915.force_probe module parameter is "unsafe" and setting it taints the kernel. However, using the kconfig option does not. Always taint the kernel when force probing a device that is not supported. v2: Drop "depends on EXPERT" to avoid build breakage (kernel test robot) Fixes: 7ef5ef5cdead ("drm/i915: add force_probe module parameter to replace alpha_support") Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Cc: Tvrtko Ursulin <tvrtko.ursulin@linux.intel.com> Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Dave Airlie <airlied@gmail.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Reviewed-by: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230504103508.1818540-1-jani.nikula@intel.com (cherry picked from commit 3312bb4ad09ca6423bd4a5b15a94588a8962fb8e) Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>
