media: uapi: rkisp: Correct name version enum

2026-08-09T18:23:24+00:00

[ Upstream commit c4c01c4fd4a3916ffdfb35ad9f511c48e289f51c ] The name of the enum to hold the mapping of parameter buffer versions have a typo in the name, correct it. While this is a uAPI header the impact should be minimal as the enum is only used as a collection for the one version number supported.

dpll: add clock quality level attribute and op

[ Upstream commit a1afb959add1fad43cb337448c244ed70bac3109 ] In order to allow driver expose quality level of the clock it is running, introduce a new netlink attr with enum to carry it to the userspace.

btrfs: declare btrfs_ioctl_search_args_v2::buf as __u8

2026-08-03T09:17:08+00:00

[ Upstream commit b95181f3929ff98949fa9460ca93eccebbf2d7fc ] The variable-sized buffer buf in struct btrfs_ioctl_search_args_v2 is declared as __u64[], but it holds a packed byte stream of search results, where all offsets into the buffer are in bytes. Declaring buf as __u64[] makes it easy for user space to write incorrect pointer arithmetic: adding a byte offset directly to a __u64 pointer scales the offset by 8, landing at byte position offset*8 instead of offset. This recently caused an infinite loop in btrfs-progs: the accessor read all-zero data from misaddressed items, which fed zeroed search keys back into the ioctl loop and spun forever. The issue was worked around at the time by disabling TREE_SEARCH_V2 entirely in btrfs-progs (d73e69824854: "btrfs-progs: temporarily disable usage of v2 of search tree ioctl"). The kernel side already treats buf as a byte buffer, so change the declaration to __u8[] to match the actual semantics and prevent similar misuse in user space. The change is ABI compatible: both the structure size and alignment are unchanged.

bpf: Check tail zero of bpf_prog_info

2026-07-24T14:10:55+00:00

[ Upstream commit 786be2b05980a5828e67fc564ad7517e2adbe9bd ] Since there're 4 bytes padding at the end of struct bpf_prog_info, they won't be checked by bpf_check_uarg_tail_zero(). pahole -C bpf_prog_info ./vmlinux struct bpf_prog_info { ... __u32 attach_btf_obj_id; /* 220 4 */ __u32 attach_btf_id; /* 224 4 */ /* size: 232, cachelines: 4, members: 38 */ /* sum members: 224 */ /* sum bitfield members: 1 bits, bit holes: 1, sum bit holes: 31 bits */ /* padding: 4 */ /* forced alignments: 9 */ /* last cacheline: 40 bytes */ } __attribute__((__aligned__(8))); If a future kernel extension adds a new 4-byte field, older userspace programs allocating this structure on the stack might inadvertently pass uninitialized stack garbage into the new field, permanently breaking backward compatibility. -- sashiko [1] Fix it by changing sizeof(info) to offsetofend(struct bpf_prog_info, attach_btf_id). And, add "__u32 :32" to the tail of struct bpf_prog_info.

[ Upstream commit 6b6dc81ee7e8ca87c71a533e1d69cf96a4f1e986 ] Introduce a new netlink attribute 'actor_port_prio' to allow setting the LACP actor port priority on a per-slave basis. This extends the existing bonding infrastructure to support more granular control over LACP negotiations. The priority value is embedded in LACPDU packets and will be used by subsequent patches to influence aggregator selection policies.

net: phy: qcom: at803x: Use the correct bit to disable extended next page

2026-05-23T11:04:26+00:00

[ Upstream commit e7a62edd34b1b4bc5f979988efc2f81c075733fd ] As noted in the blamed commit, the AR8035 and other PHYs from this family advertise the Extended Next Page support by default, which may be understood by some partners as this PHY being multi-gig capable. The fix is to disable XNP advertising, which is done by setting bit 12 of the Auto-Negotiation Advertisement Register (MII_ADVERTISE). The blamed commit incorrectly uses MDIO_AN_CTRL1_XNP, which is bit 13 as per 802.3 : 45.2.7.1 AN control register (Register 7.0) BIT 12 in MII_ADVERTISE is wrapped by ADVERTISE_RESV, used by some drivers such as the aquantia one. 802.3 Clause 28 defines bit 12 as Extended Next Page ability, at least in recent versions of the standard. Let's add a define for it and use it in the at803x driver.
