* Merge pull request #180 from fbriere/issue/165-deadlocks-complexLuboš Doležel2020-02-23-4/+4
|\ | | | | Introduce read-write-update locks and guards to prevent deadlocks
| * Fix "REFER declined" deadlockFrédéric Brière2019-12-27-1/+1
| | | | | | | | | | | | | | | | | | This occurs when the user declines an incoming call transfer request, due to the following path: - recvd_refer_permission() acquires a read lock over lines_mtx - move_releasing_lines_to_background() is called - A write lock over lines_mtx is acquired
| * Fix "Transfer with consultation without Replaces" deadlockFrédéric Brière2019-12-27-1/+1
| | | | | | | | | | | | | | | | | | | | | | This occurs when performing a consult transfer if the target does not support the Replaces extension, due to the following path: - refer() acquires a read lock over lines_mtx - refer_consultation() is called - A write lock over lines_mtx is acquired Closes #118
| * Fix "NOTIFY received when line is idle" deadlockFrédéric Brière2019-12-27-1/+1
| | | | | | | | | | | | | | | | | | | | This can easily be triggered by starting a blind transfer, and hanging up before the other end has accepted/rejected it, due to the following path: - recvd_notify() acquires a read lock on lines_mtx - cleanup_dead_lines() is called - A write lock on lines_mtx is acquired
| * Fix "INVITE with Replaces header" deadlockFrédéric Brière2019-12-27-1/+1
| | | | | | | | | | | | | | | | | | This occurs on reception of an INVITE with a Replaces header, due to the following path: - recvd_invite() acquires a read lock on lines_mtx - recvd_initial_invite() is called - A write lock over lines_mtx is acquired

| * | Prevent recursive locking of phone_users_mtx in add_phone_user()Frédéric Brière2019-07-03-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | When encountering two users with the same contact name, attempting to differentiate them using USER_HOST(), a.k.a. get_ip_sip(), would result in EDEADLK since phone_users_mtx was already locked by add_phone_user(). Closes #88
