We might end up calling client_close() from start_reply(), but that
will free the fcgi/proxy bufferevent while they're still used on the
stack.
Instead, start_reply() only sets REQUEST_DONE and exits, returning the
error eventually, so callers know when to stop.
Attempt to do also a few more steps that were previously done only
at runtime. This can help verifying that the keypairs are matching
for example, but also that there are no typos in the path to the
root directories.
Was requested some time ago by Marian Mizik, thanks for the feature
request!
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.
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.
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>'.
get rid of check_path(), it's overly complicated. Instead, inline
open_file() in client_read() and rework open_dir() to just use
openat() instead of the complicate dance it was doing.
Simplify open_dir() too in the process: if the directory entry for the
index is not a regular file, pretend it doesn't exist.
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.
We dup(1) the ca fd and send it to various processes, so they fail
loading it. Instead, use load_file to get a buffer with the file
content and pass that to load_ca which then loads via BIO.
Incorporate the OpenSMTPD' privsep crypto engine. The idea behind
it is to never load the certificate' private keys in a networked
process, instead they are loaded in a separate process (the `crypto'
one) which signs payloads on the behalf of the server processes.
This way, we greatly reduce the risk of leaking the certificate'
private key should the server process be compromised.
This currently compiles only on LibreSSL (portable fix is in the
way).
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.
server_configure_done is the code we ran in IMSG_RECONF_END splitted
in a separate functions.
This is all needed for ge.c which doesn't do privsep but needs to
bootstrap the server process.
