l2cap_le_flowctl_init() can cause both div-by-zero and an integer overflow since hdev->le_mtu may not fall in the valid range. Move MTU from hci_dev to hci_conn to validate MTU and stop the connection process earlier if MTU is invalid. Also, add a missing validation in read_buffer_size() and make it return an error value if the validation fails. Now hci_conn_add() returns ERR_PTR() as it can fail due to the both a kzalloc failure and invalid MTU value. divide error: 0000 [#1] PREEMPT SMP KASAN NOPTI CPU: 0 PID: 67 Comm: kworker/u5:0 Tainted: G W 6.9.0-rc5+ #20 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.15.0-1 04/01/2014 Workqueue: hci0 hci_rx_work RIP: 0010:l2cap_le_flowctl_init+0x19e/0x3f0 net/bluetooth/l2cap_core.c:547 Code: e8 17 17 0c 00 66 41 89 9f 84 00 00 00 bf 01 00 00 00 41 b8 02 00 00 00 4c 89 fe 4c 89 e2 89 d9 e8 27 17 0c 00 44 89 f0 31 d2 <66> f7 f3 89 c3 ff c3 4d 8d b7 88 00 00 00 4c 89 f0 48 c1 e8 03 42 RSP: 0018:ffff88810bc0f858 EFLAGS: 00010246 RAX: 00000000000002a0 RBX: 0000000000000000 RCX: dffffc0000000000 RDX: 0000000000000000 RSI: ffff88810bc0f7c0 RDI: ffffc90002dcb66f RBP: ffff88810bc0f880 R08: aa69db2dda70ff01 R09: 0000ffaaaaaaaaaa R10: 0084000000ffaaaa R11: 0000000000000000 R12: ffff88810d65a084 R13: dffffc0000000000 R14: 00000000000002a0 R15: ffff88810d65a000 FS: 0000000000000000(0000) GS:ffff88811ac00000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000020000100 CR3: 0000000103268003 CR4: 0000000000770ef0 PKRU: 55555554 Call Trace: <TASK> l2cap_le_connect_req net/bluetooth/l2cap_core.c:4902 [inline] l2cap_le_sig_cmd net/bluetooth/l2cap_core.c:5420 [inline] l2cap_le_sig_channel net/bluetooth/l2cap_core.c:5486 [inline] l2cap_recv_frame+0xe59d/0x11710 net/bluetooth/l2cap_core.c:6809 l2cap_recv_acldata+0x544/0x10a0 net/bluetooth/l2cap_core.c:7506 hci_acldata_packet net/bluetooth/hci_core.c:3939 [inline] hci_rx_work+0x5e5/0xb20 net/bluetooth/hci_core.c:4176 process_one_work kernel/workqueue.c:3254 [inline] process_scheduled_works+0x90f/0x1530 kernel/workqueue.c:3335 worker_thread+0x926/0xe70 kernel/workqueue.c:3416 kthread+0x2e3/0x380 kernel/kthread.c:388 ret_from_fork+0x5c/0x90 arch/x86/kernel/process.c:147 ret_from_fork_asm+0x1a/0x30 arch/x86/entry/entry_64.S:244 </TASK> Modules linked in: ---[ end trace 0000000000000000 ]--- Fixes: 6ed58ec5 ("Bluetooth: Use LE buffers for LE traffic") Suggested-by:

On our DUT, we can see that the host issues create connection cancel command after 4-sec if there is no connection complete event for LE create connection cmd. As per core spec v5.3 section 7.8.5, advertisement interval range is- Advertising_Interval_Min Default : 0x0800(1.28s) Time Range: 20ms to 10.24s Advertising_Interval_Max Default : 0x0800(1.28s) Time Range: 20ms to 10.24s If the remote device is using adv interval of > 4 sec, it is difficult to make a connection with the current timeout value. Also, with the default interval of 1.28 sec, we will get only 3 chances to capture the adv packets with the 4 sec window. Hence we want to increase this timeout to 20sec. Signed-off-by:

The MediaTek MT7921S is a WiFi/Bluetooth combo chip that works over SDIO. WiFi and Bluetooth are separate SDIO functions within the chip. While the Bluetooth SDIO function is fully discoverable, the chip has a pin that can reset just the Bluetooth core, as opposed to the full chip. This should be described in the device tree. Add a device tree binding for the Bluetooth SDIO function of the MT7921S specifically to document the reset line. This binding is based on the MMC controller binding, which specifies one device node per SDIO function. Cc: Sean Wang <sean.wang@mediatek.com> Signed-off-by:

Previously LE flow credits were returned to the sender even if the socket's receive buffer was full. This meant that no back-pressure was applied to the sender, thus it continued to send data, resulting in data loss without any error being reported. Furthermore, the amount of credits was essentially fixed to a small amount, leading to reduced performance. This is fixed by computing the number of returned LE flow credits based on the estimated available space in the receive buffer of an L2CAP socket. Consequently, if the receive buffer is full, no credits are returned until the buffer is read and thus cleared by user-space. Since the computation of available receive buffer space can only be performed approximately (due to sk_buff overhead) and the receive buffer size may be changed by user-space after flow credits have been sent, superfluous received data is temporary stored within l2cap_pinfo. This is necessary because Bluetooth LE provides no retransmission mechanism once the data has been acked by the physical layer. If receive buffer space estimation is not possible at the moment, we fall back to providing credits for one full packet as before. This is currently the case during connection setup, when MPS is not yet available. Fixes: b1c325c2 ("Bluetooth: Implement returning of LE L2CAP credits") Signed-off-by:

CYW43439 is a Wi-Fi + Bluetooth combo device from Infineon. The Bluetooth part is capable of Bluetooth 5.2 BR/EDR/LE . This chip is present e.g. on muRata 1YN module. Extend the binding with its DT compatible using fallback compatible string to "brcm,bcm4329-bt" which seems to be the oldest compatible device. This should also prevent the growth of compatible string tables in drivers. The existing block of compatible strings is retained. Acked-by:

Also, -Wflex-array-member-not-at-end is coming in GCC-14, and we are getting ready to enable it globally. So, use the `DEFINE_FLEX()` helper for multiple on-stack definitions of a flexible structure where the size of the flexible-array member is known at compile-time, and refactor the rest of the code, accordingly. Notice that, due to the use of `__counted_by()` in `struct hci_cp_le_create_cis`, the for loop in function `hci_cs_le_create_cis()` had to be modified. Once the index `i`, through which `cp->cis[i]` is accessed, falls in the interval [0, cp->num_cis), `cp->num_cis` cannot be decremented all the way down to zero while accessing `cp->cis[]`: net/bluetooth/hci_event.c:4310: 4310 for (i = 0; cp->num_cis; cp->num_cis--, i++) { ... 4314 handle = __le16_to_cpu(cp->cis[i].cis_handle); otherwise, only half (one iteration before `cp->num_cis == i`) or half plus one (one iteration before `cp->num_cis < i`) of the items in the array will be accessed before running into an out-of-bounds issue. So, in order to avoid this, set `cp->num_cis` to zero just after the for loop. Also, make use of `aux_num_cis` variable to update `cmd->num_cis` after a `list_for_each_entry_rcu()` loop. With these changes, fix the following warnings: net/bluetooth/hci_sync.c:1239:56: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] net/bluetooth/hci_sync.c:1415:51: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] net/bluetooth/hci_sync.c:1731:51: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] net/bluetooth/hci_sync.c:6497:45: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Link: https://github.com/KSPP/linux/issues/202Signed-off-by: -

Because both MT7920 and MT7921 use the same chip ID. We use the 8th bit of fw_flavor to distingush MT7920. The original patch made a mistake to check whole fw_flavor, that makes the condition both true (dev_id == 0x7961 && fw_flavor), and makes MT7921 flow wrong. In this patch, we correct the flow to get the 8th bit value for MT7920. And the patch is verified pass with both MT7920 and MT7921. Signed-off-by:

Like the bcm43430a0 the bcm43455 BT does not support the 0xfc45 command to set the UART clock to 48 MHz and because of this it does not work at 4000000 baud. These chips are found on ACPI/x86 devices where the operating baudrate does not come from the firmware but is hardcoded at 4000000, which does not work. Make the driver_data for the "BCM2EA4" ACPI HID which is used for the bcm43455 BT point to bcm43430_device_data which limits the baudrate to 2000000. Signed-off-by:

-Wflex-array-member-not-at-end is coming in GCC-14, and we are getting ready to enable it globally. There are currently a couple of objects (`req` and `rsp`), in a couple of structures, that contain flexible structures (`struct l2cap_ecred_conn_req` and `struct l2cap_ecred_conn_rsp`), for example: struct l2cap_ecred_rsp_data { struct { struct l2cap_ecred_conn_rsp rsp; __le16 scid[L2CAP_ECRED_MAX_CID]; } __packed pdu; int count; }; in the struct above, `struct l2cap_ecred_conn_rsp` is a flexible structure: struct l2cap_ecred_conn_rsp { __le16 mtu; __le16 mps; __le16 credits; __le16 result; __le16 dcid[]; }; So, in order to avoid ending up with a flexible-array member in the middle of another structure, we use the `struct_group_tagged()` (and `__struct_group()` when the flexible structure is `__packed`) helper to separate the flexible array from the rest of the members in the flexible structure: struct l2cap_ecred_conn_rsp { struct_group_tagged(l2cap_ecred_conn_rsp_hdr, hdr, ... the rest of members ); __le16 dcid[]; }; With the change described above, we now declare objects of the type of the tagged struct, in this example `struct l2cap_ecred_conn_rsp_hdr`, without embedding flexible arrays in the middle of other structures: struct l2cap_ecred_rsp_data { struct { struct l2cap_ecred_conn_rsp_hdr rsp; __le16 scid[L2CAP_ECRED_MAX_CID]; } __packed pdu; int count; }; Also, when the flexible-array member needs to be accessed, we use `container_of()` to retrieve a pointer to the flexible structure. We also use the `DEFINE_RAW_FLEX()` helper for a couple of on-stack definitions of a flexible structure where the size of the flexible-array member is known at compile-time. So, with these changes, fix the following warnings: net/bluetooth/l2cap_core.c:1260:45: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] net/bluetooth/l2cap_core.c:3740:45: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] net/bluetooth/l2cap_core.c:4999:45: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] net/bluetooth/l2cap_core.c:7116:47: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Link: https://github.com/KSPP/linux/issues/202Signed-off-by: -

In case of a Broadcast Source that has PA enabled but no active BIG, a Broadcast Sink needs to establish PA sync and parse BASE from PA reports. This commit moves the allocation of a PA sync hcon from the BIGInfo advertising report event to the PA sync established event. After the first complete PA report, the hcon is notified to the ISO layer. A child socket is allocated and enqueued in the parent's accept queue. BIGInfo reports also need to be processed, to extract the encryption field and inform userspace. After the first BIGInfo report is received, the PA sync hcon is notified again to the ISO layer. Since a socket will be found this time, the socket state will transition to BT_CONNECTED and the userspace will be woken up using sk_state_change. Signed-off-by:

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant. Signed-off-by:
