Attach_type will be set when a link is created by user. It is better to record attach_type in bpf_link generically and have it available universally for all link types.

This patch adds coverage for the warning detected by syzkaller and fixed in the previous patch.

2025-07-11bpf: Forget ranges when refining tnum after JSETPaul Chaignon
Syzbot reported a kernel warning due to a range invariant violation on the following BPF program. 0: call bpf_get_netns_cookie 1: if r0 == 0 goto <exit> 2: if r0 & Oxffffffff goto <exit> The issue is on the path where we fall through both jumps. That path is unreachable at runtime: after insn 1, we know r0 != 0, but with the sign extension on the jset, we would only fallthrough insn 2 if r0 == 0. Unfortunately, is_branch_taken() isn't currently able to figure this out, so the verifier walks all branches. The verifier then refines the register bounds using the second condition and we end up with inconsistent bounds on this unreachable path: 1: if r0 == 0 goto <exit> r0: u64=[0x1, 0xffffffffffffffff] var_off=(0, 0xffffffffffffffff) 2: if r0 & 0xffffffff goto <exit> r0 before reg_bounds_sync: u64=[0x1, 0xffffffffffffffff] var_off=(0, 0) r0 after reg_bounds_sync: u64=[0x1, 0] var_off=(0, 0) Improving the range refinement for JSET to cover all cases is tricky. We also don't expect many users to rely on JSET given LLVM doesn't generate those instructions. So instead of improving the range refinement for JSETs, Eduard suggested we forget the ranges whenever we're narrowing tnums after a JSET. This patch implements that approach.

2025-07-11wifi: ath12k: Fix packets received in WBM error ring with REO LUT enabledNithyanantham Paramasivam
Currently, packets are being received into the WBM error ring when REO queue lookup is enabled, resulting in degraded RX performance. The issue arises because the REO queue LUT TID memory reference is set to zero-it's being assigned before the memory is allocated. Fix this by assigning the REO queue TID memory reference in the LUT immediately after memory allocation to ensure correct packet processing.

2025-07-11netlink: make sure we allow at least one dump skbJakub Kicinski
Commit under Fixes tightened up the memory accounting for Netlink sockets. Looks like the accounting is too strict for some existing use cases, Marek reported issues with nl80211 / WiFi iw CLI. To reduce number of iterations Netlink dumps try to allocate messages based on the size of the buffer passed to previous recvmsg() calls. If user space uses a larger buffer in recvmsg() than sk_rcvbuf we will allocate an skb we won't be able to queue. Make sure we always allow at least one skb to be queued. Same workaround is already present in netlink_attachskb(). Alternative would be to cap the allocation size to rcvbuf - rmem_alloc but as I said, the workaround is already present in other places.

2025-07-11net/mlx5e: Add new prio for promiscuous modeJianbo Liu
An optimization for promiscuous mode adds a high-priority steering table with a single catch-all rule to steer all traffic directly to the TTC table. However, a gap exists between the creation of this table and the insertion of the catch-all rule. Packets arriving in this brief window would miss as no rule was inserted yet, unnecessarily incrementing the 'rx_steer_missed_packets' counter and dropped. This patch resolves the issue by introducing a new prio for this table, placing it between MLX5E_TC_PRIO and MLX5E_NIC_PRIO. By doing so, packets arriving during the window now fall through to the next prio (at MLX5E_NIC_PRIO) instead of being dropped.

2025-07-11net/mlx5e: Fix race between DIM disable and net_dim()Carolina Jubran
There's a race between disabling DIM and NAPI callbacks using the dim pointer on the RQ or SQ. If NAPI checks the DIM state bit and sees it still set, it assumes `rq->dim` or `sq->dim` is valid. But if DIM gets disabled right after that check, the pointer might already be set to NULL, leading to a NULL pointer dereference in net_dim(). Fix this by calling `synchronize_net()` before freeing the DIM context. This ensures all in-progress NAPI callbacks are finished before the pointer is cleared. Kernel log: BUG: kernel NULL pointer dereference, address: 0000000000000000 ... RIP: 0010:net_dim+0x23/0x190 ...

2025-07-10drm/xe/guc: Default log level to non-verboseLucas De Marchi
Currently xe sets the guc log level to a verbose level since it's useful to debug hangs and general development. However the verbose level may already be too much and affect performance. Michal Mrozek did some tests with the L0 compute stack for submission latency with ULLS disabled. Below are the normalized numbers with log level 3 (the current default) as baseline for each test: Test \ Log Level 3 0 1 2 ----------------------------------------------------------- ------ ------ ------ ------ BestWalkerNthCommandListSubmission(CmdListCount=2) 1.00 0.63 0.63 0.96 BestWalkerNthSubmission(KernelCount=2) 1.00 0.62 0.63 0.96 BestWalkerNthSubmissionImmediate(KernelCount=2) 1.00 0.58 0.58 0.85 BestWalkerSubmission 1.00 0.62 0.62 0.96 BestWalkerSubmissionImmediate 1.00 0.63 0.62 0.96 BestWalkerSubmissionImmediateMultiCmdlists(cmdlistCount=2) 1.00 0.58 0.58 0.86 BestWalkerSubmissionImmediateMultiCmdlists(cmdlistCount=4) 1.00 0.70 0.70 0.83 BestWalkerSubmissionImmediateMultiCmdlists(cmdlistCount=8) 1.00 0.53 0.52 0.78 Log level 2 is the first "verbose level" for GuC, where the biggest difference happens. Keep log level 3 for CONFIG_DRM_XE_DEBUG, but switch to 1, i.e. GUC_LOG_LEVEL_NON_VERBOSE, for "normal" builds.
