fuse: add feature flag for expire-only

2023-07-27T06:56:34Z

commit 5cadfbd5a11e5495cac217534c5f788168b1afd7 upstream. Add an init flag idicating whether the FUSE_EXPIRE_ONLY flag of FUSE_NOTIFY_INVAL_ENTRY is effective. This is needed for backports of this feature, otherwise the server could just check the protocol version.

autofs: use flexible array in ioctl structure

2023-07-19T14:36:54Z

commit e910c8e3aa02dc456e2f4c32cb479523c326b534 upstream. Commit df8fc4e934c1 ("kbuild: Enable -fstrict-flex-arrays=3") introduced a warning for the autofs_dev_ioctl structure: In function 'check_name', inlined from 'validate_dev_ioctl' at fs/autofs/dev-ioctl.c:131:9, inlined from '_autofs_dev_ioctl' at fs/autofs/dev-ioctl.c:624:8: fs/autofs/dev-ioctl.c:33:14: error: 'strchr' reading 1 or more bytes from a region of size 0 [-Werror=stringop-overread] 33 | if (!strchr(name, '/')) | ^~~~~~~~~~~~~~~~~ In file included from include/linux/auto_dev-ioctl.h:10, from fs/autofs/autofs_i.h:10, from fs/autofs/dev-ioctl.c:14: include/uapi/linux/auto_dev-ioctl.h: In function '_autofs_dev_ioctl': include/uapi/linux/auto_dev-ioctl.h:112:14: note: source object 'path' of size 0 112 | char path[0]; | ^~~~ This is easily fixed by changing the gnu 0-length array into a c99 flexible array. Since this is a uapi structure, we have to be careful about possible regressions but this one should be fine as they are equivalent here. While it would break building with ancient gcc versions that predate c99, it helps building with --std=c99 and -Wpedantic builds in user space, as well as non-gnu compilers. This means we probably also want it fixed in stable kernels. Cc: stable@vger.kernel.org Cc: Kees Cook Cc: "Gustavo A. R.

media: videodev2.h: Fix struct v4l2_input tuner index comment

2023-07-19T14:36:28Z

[ Upstream commit 26ae58f65e64fa7ba61d64bae752e59e08380c6a ] VIDIOC_ENUMINPUT documentation describes the tuner field of struct v4l2_input as index: Documentation/userspace-api/media/v4l/vidioc-enuminput.rst " * - __u32 - ``tuner`` - Capture devices can have zero or more tuners (RF demodulators). When the ``type`` is set to ``V4L2_INPUT_TYPE_TUNER`` this is an RF connector and this field identifies the tuner. It corresponds to struct :c:type:`v4l2_tuner` field ``index``. For details on tuners see :ref:`tuner`. " Drivers I could find also use the 'tuner' field as an index, e.g.: drivers/media/pci/bt8xx/bttv-driver.c bttv_enum_input() drivers/media/usb/go7007/go7007-v4l2.c vidioc_enum_input() However, the UAPI comment claims this field is 'enum v4l2_tuner_type': include/uapi/linux/videodev2.h This field being 'enum v4l2_tuner_type' is unlikely as it seems to be never used that way in drivers, and documentation confirms it. It seem this comment got in accidentally in the commit which this patch fixes. Fix the UAPI comment to stop confusion. This was pointed out by Dmitry while reviewing VIDIOC_ENUMINPUT support for strace.

block: change all u32 annotations to be32 in affs_hardblocks.h

2023-07-19T14:36:22Z

commit 95a55437dc49fb3342c82e61f5472a71c63d9ed0 upstream. The Amiga partition parser module uses signed int for partition sector address and count, which will overflow for disks larger than 1 TB. Use u64 as type for sector address and size to allow using disks up to 2 TB without LBD support, and disks larger than 2 TB with LBD. The RBD format allows to specify disk sizes up to 2^128 bytes (though native OS limitations reduce this somewhat, to max 2^68 bytes), so check for u64 overflow carefully to protect against overflowing sector_t. This bug was reported originally in 2012, and the fix was created by the RDB author, Joanne Dow . A patch had been discussed and reviewed on linux-m68k at that time but never officially submitted (now resubmitted as patch 1 of this series). Patch 3 (this series) adds additional error checking and warning messages. One of the error checks now makes use of the previously unused rdb_CylBlocks field, which causes a 'sparse' warning (cast to restricted __be32). Annotate all 32 bit fields in affs_hardblocks.h as __be32, as the on-disk format of RDB and partition blocks is always big endian.

net: ethtool: correct MAX attribute value for stats

2023-06-12T07:50:48Z

When compiling YNL generated code compiler complains about array-initializer-out-of-bounds. Turns out the MAX value for STATS_GRP uses the value for STATS. This may lead to random corruptions in user space (kernel itself doesn't use this value as it never parses stats).

bpf: netfilter: Add BPF_NETFILTER bpf_attach_type

2023-06-05T22:01:43Z

Andrii Nakryiko writes: And we currently don't have an attach type for NETLINK BPF link. Thankfully it's not too late to add it. I see that link_create() in kernel/bpf/syscall.c just bypasses attach_type check. We shouldn't have done that. Instead we need to add BPF_NETLINK attach type to enum bpf_attach_type. And wire all that properly throughout the kernel and libbpf itself. This adds BPF_NETFILTER and uses it. This breaks uabi but this wasn't in any non-rc release yet, so it should be fine. v2: check link_attack prog type in link_create too Fixes: 84601d6ee68a ("bpf: add bpf_link support for BPF_NETFILTER programs") Suggested-by: Andrii Nakryiko Signed-off-by: Florian Westphal Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/CAEf4BzZ69YgrQW7DHCJUT_X+GqMq_ZQQPBwopaJJVGFD5=d5Vg@mail.gmail.com/ Link: https://lore.kernel.org/bpf/20230605131445.32016-1-fw@strlen.de
