2025-07-11wifi: iwlwifi: add support for accepting raw DSM tables by firmwarePagadala Yesu Anjaneyulu
Firmware would assert on undefined bits in DSM-originated DWs. With this change, Firmware introduces a fail-safe mechanism and removes the assert behavior. This ensures robustness when handling raw DSM table data.

2025-07-11wifi: iwlwifi: mld: don't remove all keys in mcast rekeyMiri Korenblit
In the current code, if there was a rekey, we remove all the existing keys from mac80211, then re-add the ones that the FW sent with ieee80211_gtk_rekey_add, (newer FW will send also the existing GTKs/BIGTKs) and then update the sequence number. Instead of removing and re-adding the existing keys for no good reason, we can just update the sequence of all keys, also of the ones that are going to be replaced, and update again after the replace. This change is required because ieee80211_gtk_rekey_add is going to be changed to lookup the cipher from the old key instead of receiving it as an argument, and for this it will need the old key(s), so we can't remove all keys. Note that with this change, in case that a key that existed before wowlan is replaced, mac80211 will now call the driver to remove the old key and add the new one (as opposed the previous behaviour, in which the key was removed by the driver itself). Of course we don't want to run the set_key callbacks in this case, so just return early.

2025-07-11wifi: iwlwifi: fix HE/EHT capabilitiesJohannes Berg
The default capabilities were set to much more than the hardware currently is intended to support, and then masked off for only the GL MAC type. However, this was due to some miscommunication and is incorrect, it should've been masked off for all current and planned MACs/RFs. Instead of doing this removing and adding of capabilities, simply list the ones that currently apply to all devices. If this changes for a new device type we can change the code, but at least the driver won't erroneously advertise some capabilities that aren't actually implemented in hardware.

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 ...

2025-07-11PCI: hv: Switch to msi_create_parent_irq_domain()Nam Cao
Move away from the legacy MSI domain setup, switch to use msi_create_parent_irq_domain(). While doing the conversion, I noticed that hv_compose_msi_msg() is doing more than it is supposed to (composing message). This function also allocates and populates struct tran_int_desc, which should be done in hv_pcie_domain_alloc() instead. It works, but it is not the correct design. However, I have no hardware to test such change, therefore I leave a TODO note.

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.
