* tls: fix crash when opening priv key for writingWilliam Casarin2020-11-081-1/+1
| | | | | | | | | | | | | | | | | | | The open syscall will return a negative value if the call fails. Switch the check to look for this instead of 0. before: [gmnisrv] generating certificate for localhost gmnisrv: src/tls.c:68: tls_host_gencert: Assertion `pf' failed. abort (core dumped) ./gmnisrv -C config.ini after: [gmnisrv] generating certificate for localhost [gmnisrv] opening private key for writing failed: No such file or directory [gmnisrv] TLS initialization failed Signed-off-by: William Casarin <jb55@jb55.com>

* config/routing: fix maybe-uninitialized errorsWilliam Casarin2020-11-021-0/+2
| | | | | | | | | | | | | | | | | Trivial fix to silence compilation errors on gcc 9.3.0: src/config.c: In function ‘conf_ini_handler’: src/config.c:154:23: error: ‘routing’ may be used uninitialized in this function [-Werror=maybe-uninitialized] 154 | enum gmnisrv_routing routing; | ^~~~~~~ src/config.c:197:18: error: ‘spec’ may be used uninitialized in this function [-Werror=maybe-uninitialized] 197 | route->path = strdup(spec); | ^~~~~~~~~~~~ Signed-off-by: William Casarin <jb55@jb55.com>

* gmnisrv.ini(5): clarify tokens in route configDrew DeVault2020-11-011-4/+4
|
* Change meaning of root (backwards incompatible!)Drew DeVault2020-11-012-12/+16
| | | | | | | | | This takes the nginx approach to the "root" directive, which is simpler to implement and more consistent with more complex routing behaviors like regexp. The path component of the URL is now simply appended to the root to form the path to the file which should be served to the client.

|
* Initial pass on regex routing supportDrew DeVault2020-10-297-5/+7561
| | | | | | | | | All this does is parse the regexes out of the config file. I've vendored libregexp from Bellard's quickjs project, because it's reasonably small and self-contained, and POSIX regexes don't support captures. We're eventually going to want captures for URL rewrites, so this'll do for now.

* Overhaul network I/O to be async for realDrew DeVault2020-10-255-108/+249
| | | | | Had to totally cut off OpenSSL from the network fd because obviously OpenSSL is just going to wreck our shit
* add a missing "/" to autoindex pathsio mintz2020-10-151-2/+1
| | | | | | | | | | | | | | | | | | | | With the following directory structure: /srv/gmni: baz/ foo/ /srv/gmni/baz: a /srv/gmni/foo: bar/ /srv/gmni/foo/bar: b trying to access gemini://somesite/ with autoindex=on works, but accessing /foo fails because it tries to stat /srv/gmni/foobar instead of /srv/gmni/foo/bar. This commit fixes that by adding a trailing slash.
* serve: fix gcc-9.3.0 error in serve_autoindexWilliam Casarin2020-10-151-1/+1
| | | | | | | | | | | | | gcc 9.3.0 catches an off-by-one error with strncat in serve_autoindex where it might not write a 0 byte: In function ‘strncat’, inlined from ‘serve_autoindex’ at src/serve.c:60:3: /nix/store/...glibc-2.31-dev/include/bits/string_fortified.h:136:10: error: ‘__builtin___strncat_chk’ specified bound 4097 equals destination size [-Werror=stringop-overflow=] Signed-off-by: William Casarin <jb55@jb55.com>
* return false on request_validate errorsChris Vittal2020-10-121-1/+4
| | | | | This will report proper errors to clients rather than continuing on with request processing.

* Break after processing polled clientDrew DeVault2020-09-271-0/+3
| | | | Otherwise we might not grok it, ya jive
* Only handle one client per poll iterationDrew DeVault2020-09-271-8/+4
| | | | | This is a bit of a hack but it avoids some problems with invalid reads when a client gets disconnected
