2025-05-20selftests: net: validate team flags propagationStanislav Fomichev
Cover three recent cases: 1. missing ops locking for the lowers during netdev_sync_lower_features 2. missing locking for dev_set_promiscuity (plus netdev_ops_assert_locked with a comment on why/when it's needed) 3. rcu lock during team_change_rx_flags Verified that each one triggers when the respective fix is reverted. Not sure about the placement, but since it all relies on teaming, added to the teaming directory. One ugly bit is that I add NETIF_F_LRO to netdevsim; there is no way to trigger netdev_sync_lower_features without it.

2025-05-20wifi: ath12k: fix mac pdev frequency range updateAditya Kumar Singh
The current implementation of per-pdev frequency range updates assumes that each pdev supports only a single band. As a result in ath12k_regd_update(), bands are handled using an if-else structure, which limits updates to only one of the band per pdev. This assumption does not hold for all chipsets. For example, the WCN7850 supports multiple bands within a single pdev. Hence to accommodate such cases, update the logic to account for all band cases by handling each band in a separate if conditions instead of the previous if-else structure.

2025-05-20gpiolib: don't crash on enabling GPIO HOG pinsDmitry Baryshkov
On Qualcomm platforms if the board uses GPIO hogs msm_pinmux_request() calls gpiochip_line_is_valid(). After commit 8015443e24e7 ("gpio: Hide valid_mask from direct assignments") gpiochip_line_is_valid() uses gc->gpiodev, which is NULL when GPIO hog pins are being processed. Thus after this commit using GPIO hogs causes the following crash. In order to fix this, verify that gc->gpiodev is not NULL. Note: it is not possible to reorder calls (e.g. by calling msm_gpio_init() before pinctrl registration or by splitting pinctrl_register() into _and_init() and pinctrl_enable() and calling the latter function after msm_gpio_init()) because GPIO chip registration would fail with EPROBE_DEFER if pinctrl is not enabled at the time of registration. pc : gpiochip_line_is_valid+0x4/0x28 lr : msm_pinmux_request+0x24/0x40 sp : ffff8000808eb870 x29: ffff8000808eb870 x28: 0000000000000000 x27: 0000000000000000 x26: 0000000000000000 x25: ffff726240f9d040 x24: 0000000000000000 x23: ffff7262438c0510 x22: 0000000000000080 x21: ffff726243ea7000 x20: ffffab13f2c4e698 x19: 0000000000000080 x18: 00000000ffffffff x17: ffff726242ba6000 x16: 0000000000000100 x15: 0000000000000028 x14: 0000000000000000 x13: 0000000000002948 x12: 0000000000000003 x11: 0000000000000078 x10: 0000000000002948 x9 : ffffab13f50eb5e8 x8 : 0000000003ecb21b x7 : 000000000000002d x6 : 0000000000000b68 x5 : 0000007fffffffff x4 : ffffab13f52f84a8 x3 : ffff8000808eb804 x2 : ffffab13f1de8190 x1 : 0000000000000080 x0 : 0000000000000000 Call trace: gpiochip_line_is_valid+0x4/0x28 (P) pin_request+0x208/0x2c0 pinmux_enable_setting+0xa0/0x2e0 pinctrl_commit_state+0x150/0x26c pinctrl_enable+0x6c/0x2a4 pinctrl_register+0x3c/0xb0 devm_pinctrl_register+0x58/0xa0 msm_pinctrl_probe+0x2a8/0x584 sdm845_pinctrl_probe+0x20/0x88 platform_probe+0x68/0xc0 really_probe+0xbc/0x298 __driver_probe_device+0x78/0x12c driver_probe_device+0x3c/0x160 __device_attach_driver+0xb8/0x138 bus_for_each_drv+0x84/0xe0 __device_attach+0x9c/0x188 device_initial_probe+0x14/0x20 bus_probe_device+0xac/0xb0 deferred_probe_work_func+0x8c/0xc8 process_one_work+0x208/0x5e8 worker_thread+0x1b4/0x35c kthread+0x144/0x220 ret_from_fork+0x10/0x20 Code: b5fffba0 17fffff2 9432ec27 f9400400 (f9428800) Fixes: 8015443e24e7 ("gpio: Hide valid_mask from direct assignments") Reported-by: Doug Anderson <dianders@chromium.org> Closes: https://lore.kernel.org/r/CAD=FV=Vg8_ZOLgLoC4WhFPzhVsxXFC19NrF38W6cW_W_3nFjbw@mail.gmail.com Tested-by: Douglas Anderson <dianders@chromium.org> Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@oss.qualcomm.com> Reviewed-by: Matti Vaittinen <mazziesaccount@gmail.com> Acked-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org> Link: https://lore.kernel.org/20250513-pinctrl-msm-fix-v2-1-249999af0fc1@oss.qualcomm.com Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2025-05-20can: kvaser_pciefd: Continue parsing DMA buf after dropped RXAxel Forsman
Going bus-off on a channel doing RX could result in dropped packets. As netif_running() gets cleared before the channel abort procedure, the handling of any last RDATA packets would see netif_rx() return non-zero to signal a dropped packet. kvaser_pciefd_read_buffer() dealt with this "error" by breaking out of processing the remaining DMA RX buffer. Only return an error from kvaser_pciefd_read_buffer() due to packet corruption, otherwise handle it internally.

The functions kvaser_pciefd_start_xmit() and kvaser_pciefd_handle_ack_packet() raced to stop/wake TX queues and get/put echo skbs, as kvaser_pciefd_can->echo_lock was only ever taken when transmitting and KCAN_TX_NR_PACKETS_CURRENT gets decremented prior to handling of ACKs. E.g., this caused the following error: can_put_echo_skb: BUG! echo_skb 5 is occupied! Instead, use the synchronization helpers in netdev_queues.h. As those piggyback on BQL barriers, start updating in-flight packets and bytes counts as well.

This patch fixes that by adding the EXT4_EX_NOCACHE flag in ext4_convert_unwritten_extents_atomic() for unwritten to written conversion calls to ext4_map_blocks().

For UBLK_F_AUTO_BUF_REG, buffer is registered to uring_cmd context automatically with the provided buffer index. User may provide one wrong buffer index, or the specified buffer is registered by application already. Add UBLK_AUTO_BUF_REG_FALLBACK for supporting to auto buffer registering fallback by completing the uring_cmd and telling ublk server the register failure via UBLK_AUTO_BUF_REG_FALLBACK, then ublk server still can register the buffer from userspace. So we can provide reliable way for supporting auto buffer register.

2025-05-20ublk: prepare for supporting to register request buffer automaticallyMing Lei
UBLK_F_SUPPORT_ZERO_COPY requires ublk server to issue explicit buffer register/unregister uring_cmd for each IO, this way is not only inefficient, but also introduce dependency between buffer consumer and buffer register/ unregister uring_cmd, please see tools/testing/selftests/ublk/stripe.c in which backing file IO has to be issued one by one by IOSQE_IO_LINK. Prepare for adding feature UBLK_F_AUTO_BUF_REG for addressing the existing zero copy limitation: - register request buffer automatically to ublk uring_cmd's io_uring context before delivering io command to ublk server - unregister request buffer automatically from the ublk uring_cmd's io_uring context when completing the request - io_uring will unregister the buffer automatically when uring is exiting, so we needn't worry about accident exit For using this feature, ublk server has to create one sparse buffer table Reviewed-by: Caleb Sander Mateos <csander@purestorage.com> Signed-off-by: Ming Lei <ming.lei@redhat.com> Link: https://lore.kernel.org/r/20250520045455.515691-3-ming.lei@redhat.com Signed-off-by: Jens Axboe <axboe@kernel.dk>

2025-05-20selftests: ublk: make IO & device removal test more stressfulMing Lei
__run_io_and_remove() is used in several stress tests for running heavy IO vs. removing device meantime. However, sequential `readwrite` is taken in the fio script, which isn't correct, we should take random IO for saturating ublk device. Also turns out '--num_jobs=4' isn't stressful enough, so change it to '--num_jobs=$(nproc)'. Finally we don't cover single queue test in `test_stress_02.sh`, so add single queue test which can trigger request tag recycling easier. With above change the issue in #1 can be reproduced reliably in stress_02.sh.

2025-05-20wifi: ath12k: remove redundant regulatory rules intersection logic in hostAishwarya R
Whenever there is a change in the country code settings from the user, driver does an intersection of the regulatory rules for this new country with the original regulatory rules which were reported during initialization time. There is also similar logic running in firmware with a difference that the intersection in firmware is only done when the country code is configuration during boot up time (BDF/OTP). Firmware logic does not kick in when no country code is configured during device bring up time as the device is always expected to have the country code configured properly in the deployment. There is a debug/test use case that requires absolute regulatory rules to be used for a user configured country code when the device is not configured with a particular country code during boot up time. To support the above test use case, remove the redundant regulatory rules intersection logic in the host driver. Depend on the intersection logic in firmware when the device comes up with pre-configured country code.

2025-05-20ext4: only dirty folios when data journaling regular filesBrian Foster
fstest generic/388 occasionally reproduces a crash that looks as follows: BUG: kernel NULL pointer dereference, address: 0000000000000000 ... Call Trace: <TASK> ext4_block_zero_page_range+0x30c/0x380 [ext4] ext4_truncate+0x436/0x440 [ext4] ext4_process_orphan+0x5d/0x110 [ext4] ext4_orphan_cleanup+0x124/0x4f0 [ext4] ext4_fill_super+0x262d/0x3110 [ext4] get_tree_bdev_flags+0x132/0x1d0 vfs_get_tree+0x26/0xd0 vfs_cmd_create+0x59/0xe0 __do_sys_fsconfig+0x4ed/0x6b0 do_syscall_64+0x82/0x170 ... This occurs when processing a symlink inode from the orphan list. The partial block zeroing code in the truncate path calls ext4_dirty_journalled_data() -> folio_mark_dirty(). The latter calls mapping->a_ops->dirty_folio(), but symlink inodes are not assigned an a_ops vector in ext4, hence the crash. To avoid this problem, update the ext4_dirty_journalled_data() helper to only mark the folio dirty on regular files (for which a_ops is assigned). This also matches the journaling logic in the ext4_symlink() creation path, where ext4_handle_dirty_metadata() is called directly.
