[PATCH] binder: fix double-free in dbitmap

by Carlos Llamas

A process might fail to allocate a new bitmap when trying to expand its proc->dmap. In that case, dbitmap_grow() fails and frees the old bitmap via dbitmap_free(). However, the driver calls dbitmap_free() again when the same process terminates, leading to a double-free error: ================================================================== BUG: KASAN: double-free in binder_proc_dec_tmpref+0x2e0/0x55c Free of addr ffff00000b7c1420 by task kworker/9:1/209 CPU: 9 UID: 0 PID: 209 Comm: kworker/9:1 Not tainted 6.17.0-rc6-dirty #5 PREEMPT Hardware name: linux,dummy-virt (DT) Workqueue: events binder_deferred_func Call trace: kfree+0x164/0x31c binder_proc_dec_tmpref+0x2e0/0x55c binder_deferred_func+0xc24/0x1120 process_one_work+0x520/0xba4 [...] Allocated by task 448: __kmalloc_noprof+0x178/0x3c0 bitmap_zalloc+0x24/0x30 binder_open+0x14c/0xc10 [...] Freed by task 449: kfree+0x184/0x31c binder_inc_ref_for_node+0xb44/0xe44 binder_transaction+0x29b4/0x7fbc binder_thread_write+0x1708/0x442c binder_ioctl+0x1b50/0x2900 [...] ================================================================== Fix this issue by marking proc->map NULL in dbitmap_free().

[PATCH v12] Bluetooth: hci_qca: Fix SSR (SubSystem Restart) fail when BT_EN is pulled up by hw

by Shuai Zhang

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 driver that 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. Changes in v12: - Rewrote commit to clarify the actual issue and affected platforms. - Used imperative language to describe the fix. - Explained the role of HCI_QUIRK_NON_PERSISTENT_SETUP.

[PATCH net v1 1/1] net: usb: asix: ax88772: drop phylink use in PM to avoid MDIO runtime PM wakeups

by Oleksij Rempel

Drop phylink_{suspend,resume}() from ax88772 PM callbacks. MDIO bus accesses have their own runtime-PM handling and will try to wake the device if it is suspended. Such wake attempts must not happen from PM callbacks while the device PM lock is held. Since phylink {sus|re}sume may trigger MDIO, it must not be called in PM context. No extra phylink PM handling is required for this driver: - .ndo_open/.ndo_stop control the phylink start/stop lifecycle. - ethtool/phylib entry points run in process context, not PM. - phylink MAC ops program the MAC on link changes after resume.

[PATCH v11] Bluetooth: hci_qca: Fix SSR (SubSystem Restart) fail when BT_EN is pulled up by hw

by Shuai Zhang

When the host actively triggers SSR and collects coredump data, the Bluetooth stack sends a reset command to the controller. However, due to the inability to clear the QCA_SSR_TRIGGERED and QCA_IBS_DISABLED bits, the reset command times out. To address this, this patch clears the QCA_SSR_TRIGGERED and QCA_IBS_DISABLED flags and adds a 50ms delay after SSR, but only when HCI_QUIRK_NON_PERSISTENT_SETUP is not set. This ensures the controller completes the SSR process when BT_EN is always high due to hardware. For the purpose of HCI_QUIRK_NON_PERSISTENT_SETUP, please refer to the comment in `include/net/bluetooth/hci.h`. The HCI_QUIRK_NON_PERSISTENT_SETUP quirk is associated with BT_EN, and its presence can be used to determine whether BT_EN is defined in DTS. After SSR, host will not download the firmware, causing controller to remain in the IBS_WAKE state. Host needs to synchronize with the controller to maintain proper operation. Multiple triggers of SSR only first generate coredump file, due to memcoredump_flag no clear. add clear coredump flag when ssr completed. When the SSR duration exceeds 2 seconds, it triggers host tx_idle_timeout, which sets host TX state to sleep. due to the hardware pulling up bt_en, the firmware is not downloaded after the SSR. As a result, the controller does not enter sleep mode. Consequently, when the host sends a command afterward, it sends 0xFD to the controller, but the controller does not respond, leading to a command timeout. So reset tx_idle_timer after SSR to prevent host enter TX IBS_Sleep mode. --- Changs since v10: -- Update base patch to latest patch.

[PATCH v1] ASoC: qcom: sc8280xp: Fix sound card driver name match data for QCS8275

by Mohammad Rafi Shaik

The QCS8275 board is based on Qualcomm's QCS8300 SoC family, and all supported firmware files are located in the qcs8300 directory. The sound topology and ALSA UCM configuration files have also been migrated from the qcs8275 directory to the actual SoC qcs8300 directory in linux-firmware. With the current setup, the sound topology fails to load, resulting in sound card registration failure. This patch updates the driver match data to use the correct driver name qcs8300 for the qcs8275-sndcard, ensuring that the sound card driver correctly loads the sound topology and ALSA UCM configuration files from the qcs8300 directory.

[PATCH 6.6.y] ksmbd: fix null pointer dereference in alloc_preauth_hash()

by Subramaniam, Sujana

From: Sujana Subramaniam <sujana.subramaniam(a)sap.com> [ Upstream commit c8b5b7c5da7d0c31c9b7190b4a7bba5281fc4780 ] The Client send malformed smb2 negotiate request. ksmbd return error response. Subsequently, the client can send smb2 session setup even thought conn->preauth_info is not allocated. This patch add KSMBD_SESS_NEED_SETUP status of connection to ignore session setup request if smb2 negotiate phase is not complete.
