Soner Tari dc788862a9 Reintroduce BEV_OPT_THREADSAFE flag, after a signal 10 crash involving buffer events 
Rearrange and fix fd close locations and conn termination
 5 years ago
Soner Tari 6f2cf92e51 Do not pass BEV_OPT_THREADSAFE flag to bufferevent new socket/filter functions anymore: Multithreading issues seems to be solved now 5 years ago
Soner Tari e145ca6eed Refactor add/remove conn/child code 
Fix whitespace
 5 years ago
Soner Tari 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
 5 years ago
Soner Tari 17122fa6a8 Always keep thr load and conns list in sync 5 years ago
Soner Tari c43e359a1b Do not modify thr stats without locking, otherwise max fd stats were sometimes wrong 5 years ago
Soner Tari 3147723774 Add attribs, enclose debug params between debug macros, and improve documentation 5 years ago
Soner Tari dcaaa49f90 Improve documentation and use better names 5 years ago
Soner Tari 362a87ac6d Update documentation 5 years ago
Soner Tari 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
 5 years ago
Soner Tari bf513b1c37 Improvements 5 years ago
Soner Tari 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

Soner Tari 2f3fda5367 Do not try to close conns on the thrmgr thread after setting event callbacks and/or socket connect 
Use strncpy() instead of memcpy(), to limit max size with dest buffer
 5 years ago

Soner Tari 56c3bdf5d8 Do not try to term/close conns on the thrmgr thread after setting event callbacks and/or socket connect 5 years ago
Soner Tari 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) 5 years ago
Soner Tari 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 5 years ago
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
