This commit introduces the ability to add authenticators to filemaps.
Just like in normal routes, the authenticators will be resolved first
before allowing access to the filemap entries.
Configuration wise, the authenticator is an optional value after the
filemap config directive:
filemap / webroot myauth
In the Python API you can now pass the authenticator for a filemap entry
but turning the value of the filemap into a tuple with the first entry
being the path and the second being the auth dict:
AUTH AUTH={
"type": "cookie",
"value": "cookiename",
"redirect": "/auth/",
"verify": verify_cookie
}
domain.filemaps({
"/css/": "webroot/css",
"/secret/": ("webroot/secret", AUTH)
})
The parent process never differentiated between a worker process
asking for a shutdown or a worker process calling fatalx() when
it came to its exit code.
I made some changes here so the parent process will exit with
an exit code 1 if anything worker related went wrong (fatalx/death policy).
The coroutines results are now relayed back via PyIter_Send() and
no longer obtainable via _PyGen_FetchStopIterationValue().
This means that our kore.gather() would not be able to return any
values from any of the coroutines it governed.
Fix this by saving the object returned in PyIter_Send() and using it
later in pygather_reap_coro().
Python 3.10.x its PyIter_Send() will return PYGEN_ERROR if the
generator returned (as opposed to yielding) if the result returned
is Py_None and no argument was given to PyIter_Send(). Which is counter
intuitive since it seems it should give us a PYGEN_RETURN as per its
documentation.
It also no longer sets PyExc_StopIteration in this case so we cannot depend
on that anymore to figure out if a coroutine has finished.
This caused Kore to respond with a 500 immediately after coroutines
ran to completion as it was looking for the PyExc_StopIteration exception.
Fix this by simply doing another check if an exception happened before
we enter the code path where Kore would spew the 500.
The cmsghdr contains a length (cmsg_len) which indicates the length
of the data in combination with the cmsghdr length itself.
Remove the length of the cmsghdr before passing it back up to callers
so they don't need to bother with it.
This also fixes a mistake where we ended up copying extra data
from the ancdata buffer that was unintended.
When this code was moved from src/connection.c into src/tls_openssl.c
a return wouldn't break us out from kore_connection_handle() as
previously expected.
This ment that Kore would move the connection into established state
immediately even if SSL_accept() needed to read more.
This broke TLS client authentication as Kore its belts and suspenders
kept throwing a 403 due to the code not properly obtaining the client
certificate when expected.
The whole while (cnt-- >= 0) idiom is busted since cnt started
at 0 and if the first call to PyUnicode_FromStringAndSize() fails
then we're attempting to access -1.
use it in places explicit_bzero() used to be called.
The kore_mem_zero() is a best effort to try and let the compiler
not optimize the code away. Highly platform dependent.
This work moves all TLS / crypto related code into a tls_openssl.c
file and adds a tls_none.c which contains just stubs.
Allows compilation of Kore with TLS_BACKEND=none to remove building
against OpenSSL.
Also adds code for SHA1/SHA2 taken from openssh-portable so we don't
depend on those being present anymore in libcrypto.
It wasn't possible for the parent process to send messages
directly via kore_msg_send() to other worker processes.
This is now rectified to from the parent process one can call
kore_msg_send() with a worker destination and it'll work.
Wait for any process in our process group only instead of WAIT_ANY.
This allows the parent process to start subprocesses that end up
in different process groups which are handled in user code instead
completely (using signalfd for example).
Inside of the new route handlers the "authenticate" keyword can
be specified to let the route authenticate via a previously
configured authentication block.
The ability to do this went missing in a previous commit that overhauled
the routing structure of the configuration.
Just noticed the 5 seconds wasn't enough when renewing all
certificates in my own setup (i have about 30 ACME domains via Kore).
Bumped it to 30 seconds instead.
