sandbox also on FreeBSD with capsicum

conf & vhosts * gmid.c (main): changed behaviour: daemon off by default (main): changed -c in -C (cert option) (main): changed -k in -K (key option, for consistency with -C) (main): added -c to load a configuration (main): certs, key and doc (-C -K and -d) doesn't have a default value anymore (handle_handshake): add vhosts support

track handshakes This alter the current state machine by adding S_HANDSHAKE as the initial state. There, we ensure we did the handshake and we check SNI. ATM we simply continue in S_OPEN, but later we can add virtual host checks there, and skip to S_INITIALIZING with an error state if the client is accessing a wrong host.

avoid __dead and return at the end of main

reject non-gemini protocols with 53

s/uri/iri since we accept IRIs

fix build

fix remote_user for CGI and add -6 flag to enable ipv6

accept both ipv4 and ipv6

log also the port of the client

make FATAL and LOG inline functions other functions that aren't macros anymore. LOG went under a rename to logs because log is a builtin (the math function), or so gcc says.

macro reordering and while there replace SAFE_SETENV with an inline function. LOG is more difficult to transform into an inline function, given the string concatenations it does. The other LOG* and FATAL macros are fine as they already are.

simplify loop todo was initially there for an optimization: don't loop to MAX_USERS when you know the upper limit is todo.

simplify unveil/pledge calls

rename cgi_setpoll_on_* to cgi_poll_on_*
