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

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

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

87eb6ce004 Move conn end free function callback to conn end struct, proto ctx should not keep track of such conn end details, conn end should know which function to be called to free itself, we may have different protos on different ends of the same conn

ca959ca391 Do not call topmost callback functions directly, use them in bufferevent setup only, otherwise can possibly cause double free of ctx 
Run preexec and postexec logging and/or stats code when calling interface callback functions directly, they are mostly called in edge cases, but otherwise we would miss related logs and/or stats

e8e8071772 Defer conn free until the exit code of topmost callback functions, for both parent and child connections, this is necessary to handle error conditions correctly and terminate connections gracefully 
So introduce term flags in ctx and replace free functions with term functions to raise the term flag, this approach enables us to terminate connection anywhere in the code without causing use after free crashes
