Since bluetooth uses multiple protocols types, to avoid lockdep warnings, we need to use different lockdep classes (one for each protocol type). This is already done in bt_sock_create but it misses a couple of cases when new connections are created. This patch corrects that to fix the following warning: <4>[ 1864.732366] ======================================================= <4>[ 1864.733030] [ INFO: possible circular locking dependency detected ] <4>[ 1864.733544] 3.0.16-mid3-00007-gc9a0f62 #3 <4>[ 1864.733883] ------------------------------------------------------- <4>[ 1864.734408] t.android.btclc/4204 is trying to acquire lock: <4>[ 1864.734869] (rfcomm_mutex){+.+.+.}, at: [<c14970ea>] rfcomm_dlc_close+0x15/0x30 <4>[ 1864.735541] <4>[ 1864.735549] but task is already holding lock: <4>[ 1864.736045] (sk_lock-AF_BLUETOOTH){+.+.+.}, at: [<c1498bf7>] lock_sock+0xa/0xc <4>[ 1864.736732] <4>[ 1864.736740] which lock already depends on the new lock. <4>[ 1864.736750] <4>[ 1864.737428] <4>[ 1864.737437] the existing dependency chain (in reverse order) is: <4>[ 1864.738016] <4>[ 1864.738023] -> #1 (sk_lock-AF_BLUETOOTH){+.+.+.}: <4>[ 1864.738549] [<c1062273>] lock_acquire+0x104/0x140 <4>[ 1864.738977] [<c13d35c1>] lock_sock_nested+0x58/0x68 <4>[ 1864.739411] [<c1493c33>] l2cap_sock_sendmsg+0x3e/0x76 <4>[ 1864.739858] [<c13d06c3>] __sock_sendmsg+0x50/0x59 <4>[ 1864.740279] [<c13d0ea2>] sock_sendmsg+0x94/0xa8 <4>[ 1864.740687] [<c13d0ede>] kernel_sendmsg+0x28/0x37 <4>[ 1864.741106] [<c14969ca>] rfcomm_send_frame+0x30/0x38 <4>[ 1864.741542] [<c1496a2a>] rfcomm_send_ua+0x58/0x5a <4>[ 1864.741959] [<c1498447>] rfcomm_run+0x441/0xb52 <4>[ 1864.742365] [<c104f095>] kthread+0x63/0x68 <4>[ 1864.742742] [<c14d5182>] kernel_thread_helper+0x6/0xd <4>[ 1864.743187] <4>[ 1864.743193] -> #0 (rfcomm_mutex){+.+.+.}: <4>[ 1864.743667] [<c1061ada>] __lock_acquire+0x988/0xc00 <4>[ 1864.744100] [<c1062273>] lock_acquire+0x104/0x140 <4>[ 1864.744519] [<c14d2c70>] __mutex_lock_common+0x3b/0x33f <4>[ 1864.744975] [<c14d303e>] mutex_lock_nested+0x2d/0x36 <4>[ 1864.745412] [<c14970ea>] rfcomm_dlc_close+0x15/0x30 <4>[ 1864.745842] [<c14990d9>] __rfcomm_sock_close+0x5f/0x6b <4>[ 1864.746288] [<c1499114>] rfcomm_sock_shutdown+0x2f/0x62 <4>[ 1864.746737] [<c13d275d>] sys_socketcall+0x1db/0x422 <4>[ 1864.747165] [<c14d42f0>] syscall_call+0x7/0xb Signed-off-by: Octavian Purdila <octavian.purdila@intel.com> Acked-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> |
