cc0b94c17f Do not do anything with the conn ctx on the thrmgr thread after setting event callbacks and/or socket connect 
Always lock conn thr while reading ctx fields, otherwise we may get wrong values

79ad5e86cc Fix expired conn handling, signal 6 crash: Do not lock conn thr mutex twice while freeing expired conns 
Fix passthrough mode: Do not SSL_free() srvdst ssl anymore and do not add conn to thr conns list twice

844e68116a Move userauth from thrmgr thread to conn handling threads, and do not enable r/w callbacks until userauth succeeds 
Lock conn thread instead of thrmgr thread while adding conns (giant thrmgr lock versus conn thread level locks), so add conn thread mutex and remove thrmgr mutex
Offload thrmgr thread by moving many conn related setup to conn handling threads
Fix signal 6 crash caused by calling pxy_thrmgr_timer_cb() while failed conn is being freed, so use conn thread mutexes and defer adding conn to thr conn list until conn setup succeeds
Other fixes, improvements, and clean-up

2f3fda5367 Do not try to close conns on the thrmgr thread after setting event callbacks and/or socket connect

76a599d464 Put the getdtablecount() solution back in, otherwise sometimes, although rarely, we get "Error 24 on listener: Too many open files" nonstop, it's better to be safe(r) 2019-03-11 02:41:16 +03:00

96ecd8e4c3 Pass BEV_OPT_THREADSAFE to bufferevent_socket_new() and similar functions, otherwise if we are out of fds, we get signal 10 or 6 crashes sometimes, nothing else seems to work 2019-03-11 01:56:09 +03:00
Soner Tari
3a6f797917 Do not forget to reset sqlite stmt if userdb is busy or locked, otherwise we get stuck and go out of fds too 
Check retval of event_add() calls
Reduce frequency of userdb atime updates by not updating until idle time reaches more than half of user timeout value, otherwise privsep server can get very busy causing locked userdb
Do not care about multiple matches of IP addresses in arp cache on OpenBSD either
Performance and code reuse improvements, simplifications
