[PATCH 0/1] perf/x86/intel: Fix crash in icl_update_topdown_event()

by Angel Adetula

This patch fixes a crash in icl_update_topdown_event(). This fix has already been applied to the 'linux-6.1.y', 'linux-6.6.y', and 'linux-6.15.y' stable trees. This submission is to request application to the 'linux-6.12.y' stable tree, as it appears to be still missing there. This should also fix kernel bug CVE-2025-38322.

However there are two places that do specify a name: - In "mediatek/mt7623.dtsi", the clock for the "mediatek,mtk-btif" compatible serial device is named "main" - In "qca/ar9132.dtsi", the clock for the "ns8250" compatible serial device is named "uart" In commit d2db0d7815444 ("dt-bindings: serial: 8250: allow clock 'uartclk' and 'reg' for nxp,lpc1850-uart"), Frank Li added the restriction that two named clocks be used for the NXP platform mentioned above. Change that logic, so that an additional condition for (only) the SpacemiT platform similarly restricts the two clocks to have the names "core" and "bus". Finally, add "main" and "uart" as allowed names when a single clock is specified.

[PATCH iwl-net v1 0/4] ixgbe/ixgbevf: fix PF/VF communication issues

by Jedrzej Jagielski

Within two-step API update let's provide 2 new MBX operations: 1) request PF's link state (speed & up/down) - as legacy approach became obsolete for new E610 adapter and link state data can't be correctly provided - increasing API to 1.6 2) ask PF about supported features - for some time there is quite a mess in negotiating API versions caused by too loose approach in adding new specific (not supported by all of the drivers capable of linking with ixgbevf) feature and corresponding API versions. Now list of supported features is provided by MBX operation - increasing API to 1.7 Jedrzej Jagielski (4): ixgbevf: fix getting link speed data for E610 devices ixgbe: handle IXGBE_VF_GET_PF_LINK_STATE mailbox operation ixgbevf: fix mailbox API compatibility by negotiating supported features ixgbe: handle IXGBE_VF_FEATURES_NEGOTIATE mbox cmd drivers/net/ethernet/intel/ixgbe/ixgbe_mbx.h | 15 ++ .../net/ethernet/intel/ixgbe/ixgbe_sriov.c | 79 ++++++++ drivers/net/ethernet/intel/ixgbevf/defines.h | 1 + drivers/net/ethernet/intel/ixgbevf/ipsec.c | 10 + drivers/net/ethernet/intel/ixgbevf/ixgbevf.h | 7 + .../net/ethernet/intel/ixgbevf/ixgbevf_main.c | 34 +++- drivers/net/ethernet/intel/ixgbevf/mbx.h | 8 + drivers/net/ethernet/intel/ixgbevf/vf.c | 182 +++++++++++++++--- drivers/net/ethernet/intel/ixgbevf/vf.h | 1 + 9 files changed, 304 insertions(+), 33 deletions(-) -- 2.31.1

My commit from the gitlab repo is the correct one. But I personally don't have the shiftmq6 device to smoke test before sending the patch. That's why I was hesitant to send it upstream. I have now requested someone to confirm if the touchscreen works with my gitlab commit. If if its all good, I will send the correct patch later. Regards, Joel

[PATCH rtw v4 2/4] wifi: rtw89: fix tx_wait initialization race

by Fedor Pchelkin

Now that nullfunc skbs are recycled in a separate work item in the driver, the following race during initialization and processing of those skbs might lead to noticeable bugs: Waiting thread Completing thread rtw89_core_send_nullfunc() rtw89_core_tx_write_link() ... rtw89_pci_txwd_submit() skb_data->wait = NULL /* add skb to the queue */ skb_queue_tail(&txwd->queue, skb) rtw89_pci_napi_poll() ... rtw89_pci_release_txwd_skb() /* get skb from the queue */ skb_unlink(skb, &txwd->queue) rtw89_pci_tx_status() rtw89_core_tx_wait_complete() /* use incorrect skb_data->wait */ rtw89_core_tx_kick_off_and_wait() /* assign skb_data->wait but too late */ The value of skb_data->wait indicates whether skb is passed on to the core ieee80211 stack or released by the driver itself. So assure that by the time skb is added to txwd queue and becomes visible to the completing side, it has already allocated tx_wait-related data (in case it's needed). Found by Linux Verification Center (linuxtesting.org).
