2026-01-29lsm: preserve /proc/sys/vm/mmap_min_addr when !CONFIG_SECURITYPaul Moore
While reworking the LSM initialization code the /proc/sys/vm/mmap_min_addr handler was inadvertently caught up in the change and the procfs entry wasn't setup when CONFIG_SECURITY was not selected at kernel build time. This patch restores the previous behavior and ensures that the procfs entry is setup regardless of the CONFIG_SECURITY state. Future work will improve upon this, likely by moving the procfs handler into the mm subsystem, but this patch should resolve the immediate regression.

2026-01-29Bluetooth: L2CAP: Fix not tracking outstanding TX identLuiz Augusto von Dentz
This attempts to proper track outstanding request by using struct ida and allocating from it in l2cap_get_ident using ida_alloc_range which would reuse ids as they are free, then upon completion release the id using ida_free. This fixes the qualification test case L2CAP/COS/CED/BI-29-C which attempts to check if the host stack is able to work after 256 attempts to connect which requires Ident field to use the full range of possible values in order to pass the test.

2026-01-29Bluetooth: MGMT: Fix memory leak in set_ssp_completeJianpeng Chang
Fix memory leak in set_ssp_complete() where mgmt_pending_cmd structures are not freed after being removed from the pending list. Commit 302a1f674c00 ("Bluetooth: MGMT: Fix possible UAFs") replaced mgmt_pending_foreach() calls with individual command handling but missed adding mgmt_pending_free() calls in both error and success paths of set_ssp_complete(). Other completion functions like set_le_complete() were fixed correctly in the same commit. This causes a memory leak of the mgmt_pending_cmd structure and its associated parameter data for each SSP command that completes. Add the missing mgmt_pending_free(cmd) calls in both code paths to fix the memory leak. Also fix the same issue in set_advertising_complete().

2026-01-29Bluetooth: hci_uart: fix null-ptr-deref in hci_uart_write_workJia-Hong Su
hci_uart_set_proto() sets HCI_UART_PROTO_INIT before calling hci_uart_register_dev(), which calls proto->open() to initialize hu->priv. However, if a TTY write wakeup occurs during this window, hci_uart_tx_wakeup() may schedule write_work before hu->priv is initialized, leading to a NULL pointer dereference in hci_uart_write_work() when proto->dequeue() accesses hu->priv. The race condition is: CPU0 CPU1 ---- ---- hci_uart_set_proto() set_bit(HCI_UART_PROTO_INIT) hci_uart_register_dev() tty write wakeup hci_uart_tty_wakeup() hci_uart_tx_wakeup() schedule_work(&hu->write_work) proto->open(hu) // initializes hu->priv hci_uart_write_work() hci_uart_dequeue() proto->dequeue(hu) // accesses hu->priv (NULL!) Fix this by moving set_bit(HCI_UART_PROTO_INIT) after proto->open() succeeds, ensuring hu->priv is initialized before any work can be scheduled.

One big Qualcomm Bluetooth schema is hardly manageable: it lists all possible properties (19 supplies). Split common part and qcom,qca2066-bt to separate bindings, so each schema will be easier to read/maintain and list only relevant properties. The existing bindings do not mention interrupts, but am335x-sancloud-bbe-extended-wifi.dts already defines such. This issue is not being fixed here. Existing binding also did not mention any supplies (which do exist as confirmed in datasheet) and Linux driver does not ask for any, thus keep this state unchanged.

2026-01-29Bluetooth: Fix using PHYs bitfields as PHY valueLuiz Augusto von Dentz
This renames the PHY fields in bt_iso_io_qos to PHYs (plural) since it represents a bitfield where multiple PHYs can be set and make the same change also to HCI_OP_LE_SET_CIG_PARAMS since both c_phy and p_phy fields are bitfields. This also fixes the assumption that hci_evt_le_cis_established PHYs fields are compatible with bt_iso_io_qos, they are not, the fields in hci_evt_le_cis_established represent just a single PHY value so they need to be converted to bitfield when set in bt_iso_io_qos.

2026-01-29Bluetooth: hci_qca: Fix SSR (SubSystem Restart) fail when BT_EN is pulled up ↵Shuai Zhang
by hw On QCS9075 and QCA8275 platforms, the BT_EN pin is always pulled up by hw and cannot be controlled by the host. As a result, in case of a firmware crash, the host cannot trigger a cold reset. Instead, the BT controller performs a warm restart on its own, without reloading the firmware. This leads to the controller remaining in IBS_WAKE state, while the host expects it to be in sleep mode. The mismatch causes HCI reset commands to time out. Additionally, the driver does not clear internal flags QCA_SSR_TRIGGERED and QCA_IBS_DISABLED, which blocks the reset sequence. If the SSR duration exceeds 2 seconds, the host may enter TX sleep mode due to tx_idle_timeout, further preventing recovery. Also, memcoredump_flag is not cleared, so only the first SSR generates a coredump. Tell the driver that the BT controller has undergone a proper restart sequence: - Clear QCA_SSR_TRIGGERED and QCA_IBS_DISABLED flags after SSR. - Add a 50ms delay to allow the controller to complete its warm reset. - Reset tx_idle_timer to prevent the host from entering TX sleep mode. - Clear memcoredump_flag to allow multiple coredump captures. Apply these steps only when HCI_QUIRK_NON_PERSISTENT_SETUP is not set, which indicates that BT_EN is defined in DTS and cannot be toggled. Refer to the comment in include/net/bluetooth/hci.h for details on HCI_QUIRK_NON_PERSISTENT_SETUP.

2026-01-29cxl: Fix premature commit_end increment on decoder commit failureYuxiong Wang
In cxl_decoder_commit(), commit_end is incremented before verifying whether the commit succeeded, and the CXL_DECODER_F_ENABLE bit in cxld->flags is only set after a successful commit. As a result, if the commit fails, commit_end has been incremented and cxld->reset() has no effect since the flag is not set, so commit_end remains incorrectly incremented. The inconsistency between commit_end and CXL_DECODER_F_ENABLE causes failure during subsequent either commit or reset operations. Fix this by incrementing commit_end only after confirming the commit succeeded. Also, remove the ineffective cxld->reset() call. According to CXL Spec r4.0 8.2.4.20.12 Committing Decoder Programming, since cxld_await_commit() has cleared the decoder commit bit on failure, no additional reset is required.
