Omar Polo 8aba5d8b21 remove dead code 2024-03-12 14:10:36 +00:00
Omar Polo f862d389ff turn log styles into strings from yacc point of view 
having styles as reserved keywords means that variables / macros can't
be called `common', `condensed', etc...  which is not great and not
obvious either.

Instead, let's keep the log styles as strings and match on them.  This
also allows to have a slightly better error message in case of a typo.

Omar Polo 9abba172b6 add `log syslog facility' to use a different syslog(3) facility 
Was requested ages ago by Karl Jeacle, now that there is some better
support for configuring the logging there's no excuse to add this.
It helps with filtering from syslog.d / syslog.conf.

Omar Polo abd261d25b allow to change the logging style; introduce some new ones 
add `log style <style>'; The old default is called `legacy' now, a
new default format is added called `condensed', and `common' and
`combined' to mimick Apache httpd and nginx (respectively) are also
added.

Omar Polo 3d56cb5336 fix a reduce/reduce conflict

Omar Polo 6a8387e5f5 add `fastcgi off' to forceful skip fastcgi for a route 2023-07-23 19:04:37 +00:00
Omar Polo a1ba9650a9 revamp fastcgi configuration: make it per-location 
this revamps the syntax in the configuration to better match httpd(8)
(and in general be less weird) and to allow per-location fastcgi
configurations.

the bare `param' is now deprecated, but for compatibility it acts
like `fastcgi param' would do now.  Same story for `fastcgi <pathÂ>'.

Omar Polo a7a998ac9b fix `listen on *' 2023-06-23 21:59:11 +00:00
Omar Polo 509d0509a5 implement `listen on' 
Listening by default on all the addresses is so bad I don't know
why I haven't changed this before.  Anyway.

Add a `listen on $hostname port $port' syntax to the config file
and deprecate the old "port" and "ipv6" global setting.  Still try
to honour them when no "listen on" directive is used for backward
compatibily, but this will go away in the next next version hopefully.

At the moment the `listen on' in server context don't filter the
host, i.e. one can still reach a host from a address not specified
in the corresponding `liste on', this will be added later.

file.

Omar Polo deadd9e131 readd proxy certs and `require client ca' support 
Was temporarly disabled during the transition to real privsep.
While here, fix a memory leak when using `require client ca'.

Also, avoid leaking info about the parent address space layout to
server processes by not sending pointer values.

Omar Polo c26f2460e4 rework the daemon to do fork+exec 
It uses the 'common' proc.c from various OpenBSD-daemons.

gmid grew organically bit by bit and it was also the first place where I
tried to implement privsep.  It wasn't done very well, in fact the
parent process (that retains root privileges) just fork()s a generation
of servers, all sharing *exactly* the same address space.  No good!

Now, we fork() and re-exec() ourselves, so that each process has a fresh
address space.

Some features (require client ca for example) are temporarly disabled,
will be fixed in subsequent commits.  The "ge" program is also
temporarly disabled as it needs tweaks to do privsep too.

Omar Polo 9715efe6f3 retire fcgi' prog field
