2024-03-06selftests/harness: Fix TEST_F()'s vfork handlingMickaël Salaün
Always run fixture setup in the grandchild process, and by default also run the teardown in the same process. However, this change makes it possible to run the teardown in a parent process when _metadata->teardown_parent is set to true (e.g. in fixture setup). Fix TEST_SIGNAL() by forwarding grandchild's signal to its parent. Fix seccomp tests by running the test setup in the parent of the test thread, as expected by the related test code. Fix Landlock tests by waiting for the grandchild before processing _metadata. Use of exit(3) in tests should be OK because the environment in which the vfork(2) call happen is already dedicated to the running test (with flushed stdio, setpgrp() call), see __run_test() and the call to fork(2) just before running the setup/test/teardown. Even if the test configures its own exit handlers, they will not be run by the parent because it never calls exit(3), and the test function either ends with a call to _exit(2) or a signal.

2024-03-06mptcp: drop lookup_by_id in lookup_addrGeliang Tang
When the lookup_by_id parameter of __lookup_addr() is true, it's the same as __lookup_addr_by_id(), it can be replaced by __lookup_addr_by_id() directly. So drop this parameter, let __lookup_addr() only looks up address on the local address list by comparing addresses in it, not address ids.

2024-03-07netfilter: nf_tables: mark set as dead when unbinding anonymous set with timeoutPablo Neira Ayuso
While the rhashtable set gc runs asynchronously, a race allows it to collect elements from anonymous sets with timeouts while it is being released from the commit path. Mingi Cho originally reported this issue in a different path in 6.1.x with a pipapo set with low timeouts which is not possible upstream since 7395dfacfff6 ("netfilter: nf_tables: use timestamp to check for set element timeout"). Fix this by setting on the dead flag for anonymous sets to skip async gc in this case. According to 08e4c8c5919f ("netfilter: nf_tables: mark newset as dead on transaction abort"), Florian plans to accelerate abort path by releasing objects via workqueue, therefore, this sets on the dead flag for abort path too.

2024-03-06Bluetooth: Add new quirk for broken read key length on ATS2851Vinicius Peixoto
The ATS2851 controller erroneously reports support for the "Read Encryption Key Length" HCI command. This makes it unable to connect to any devices, since this command is issued by the kernel during the connection process in response to an "Encryption Change" HCI event.

2024-03-06Bluetooth: btrtl: fix out of bounds memory accessAndrey Skvortsov
The problem is detected by KASAN. btrtl driver uses private hci data to store 'struct btrealtek_data'. If btrtl driver is used with btusb, then memory for private hci data is allocated in btusb. But no private data is allocated after hci_dev, when btrtl is used with hci_h5. This commit adds memory allocation for hci_h5 case. ================================================================== BUG: KASAN: slab-out-of-bounds in btrtl_initialize+0x6cc/0x958 [btrtl] Write of size 8 at addr ffff00000f5a5748 by task kworker/u9:0/76 Hardware name: Pine64 PinePhone (1.2) (DT) Workqueue: hci0 hci_power_on [bluetooth] Call trace: dump_backtrace+0x9c/0x128 show_stack+0x20/0x38 dump_stack_lvl+0x48/0x60 print_report+0xf8/0x5d8 kasan_report+0x90/0xd0 __asan_store8+0x9c/0xc0 [btrtl] h5_btrtl_setup+0xd0/0x2f8 [hci_uart] h5_setup+0x50/0x80 [hci_uart] hci_uart_setup+0xd4/0x260 [hci_uart] hci_dev_open_sync+0x1cc/0xf68 [bluetooth] hci_dev_do_open+0x34/0x90 [bluetooth] hci_power_on+0xc4/0x3c8 [bluetooth] process_one_work+0x328/0x6f0 worker_thread+0x410/0x778 kthread+0x168/0x178 ret_from_fork+0x10/0x20 Allocated by task 53: kasan_save_stack+0x3c/0x68 kasan_save_track+0x20/0x40 kasan_save_alloc_info+0x68/0x78 __kasan_kmalloc+0xd4/0xd8 __kmalloc+0x1b4/0x3b0 hci_alloc_dev_priv+0x28/0xa58 [bluetooth] hci_uart_register_device+0x118/0x4f8 [hci_uart] h5_serdev_probe+0xf4/0x178 [hci_uart] serdev_drv_probe+0x54/0xa0 really_probe+0x254/0x588 __driver_probe_device+0xc4/0x210 driver_probe_device+0x64/0x160 __driver_attach_async_helper+0x88/0x158 async_run_entry_fn+0xd0/0x388 process_one_work+0x328/0x6f0 worker_thread+0x410/0x778 kthread+0x168/0x178 ret_from_fork+0x10/0x20 Last potentially related work creation: kasan_save_stack+0x3c/0x68 __kasan_record_aux_stack+0xb0/0x150 kasan_record_aux_stack_noalloc+0x14/0x20 __queue_work+0x33c/0x960 queue_work_on+0x98/0xc0 hci_recv_frame+0xc8/0x1e8 [bluetooth] h5_complete_rx_pkt+0x2c8/0x800 [hci_uart] h5_rx_payload+0x98/0xb8 [hci_uart] h5_recv+0x158/0x3d8 [hci_uart] hci_uart_receive_buf+0xa0/0xe8 [hci_uart] ttyport_receive_buf+0xac/0x178 flush_to_ldisc+0x130/0x2c8 process_one_work+0x328/0x6f0 worker_thread+0x410/0x778 kthread+0x168/0x178 ret_from_fork+0x10/0x20 Second to last potentially related work creation: kasan_save_stack+0x3c/0x68 __kasan_record_aux_stack+0xb0/0x150 kasan_record_aux_stack_noalloc+0x14/0x20 __queue_work+0x788/0x960 queue_work_on+0x98/0xc0 __hci_cmd_sync_sk+0x23c/0x7a0 [bluetooth] __hci_cmd_sync+0x24/0x38 [bluetooth] btrtl_initialize+0x760/0x958 [btrtl] h5_btrtl_setup+0xd0/0x2f8 [hci_uart] h5_setup+0x50/0x80 [hci_uart] hci_uart_setup+0xd4/0x260 [hci_uart] hci_dev_open_sync+0x1cc/0xf68 [bluetooth] hci_dev_do_open+0x34/0x90 [bluetooth] hci_power_on+0xc4/0x3c8 [bluetooth] process_one_work+0x328/0x6f0 worker_thread+0x410/0x778 kthread+0x168/0x178 ret_from_fork+0x10/0x20 ================================================================== Fixes: 5b355944b190 ("Bluetooth: btrtl: Add btrealtek data struct") Fixes: 044014ce85a1 ("Bluetooth: btrtl: Add Realtek devcoredump support") Signed-off-by: Andrey Skvortsov <andrej.skvortzov@gmail.com> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

2024-03-06Bluetooth: Remove pending ACL connection attemptsJonas Dreßler
With the last commit we moved to using the hci_sync queue for "Create Connection" requests, removing the need for retrying the paging after finished/failed "Create Connection" requests and after the end of inquiries. hci_conn_check_pending() was used to trigger this retry, we can remove it now. Note that we can also remove the special handling for COMMAND_DISALLOWED errors in the completion handler of "Create Connection", because "Create Connection" requests are now always serialized. This is somewhat reverting commit 4c67bc74f016 ("[Bluetooth] Support concurrent connect requests"). With this, the BT_CONNECT2 state of ACL hci_conn objects should now be back to meaning only one thing: That we received a "Connection Request" from another device (see hci_conn_request_evt), but the response to that is going to be deferred.

2024-03-06Bluetooth: hci_conn: Only do ACL connections sequentiallyJonas Dreßler
Pretty much all bluetooth chipsets only support paging a single device at a time, and if they don't reject a secondary "Create Connection" request while another is still ongoing, they'll most likely serialize those requests in the firware. With commit 4c67bc74f016 ("[Bluetooth] Support concurrent connect requests") we started adding some serialization of our own in case the adapter returns "Command Disallowed" HCI error. This commit was using the BT_CONNECT2 state for the serialization, this state is also used for a few more things (most notably to indicate we're waiting for an inquiry to cancel) and therefore a bit unreliable. Also not all BT firwares would respond with "Command Disallowed" on too many connection requests, some will also respond with "Hardware Failure" (BCM4378), and others will error out later and send a "Connect Complete" event with error "Rejected Limited Resources" (Marvell 88W8897). We can clean things up a bit and also make the serialization more reliable by using our hci_sync machinery to always do "Create Connection" requests in a sequential manner. This is very similar to what we're already doing for establishing LE connections, and it works well there. Note that this causes a test failure in mgmt-tester (test "Pair Device - Power off 1") because the hci_abort_conn_sync() changes the error we return on timeout of the "Create Connection". We'll fix this on the mgmt-tester side by adjusting the expected error for the test. Signed-off-by: Jonas Dreßler <verdre@v0yd.nl> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
