2022/03/27 - 1.8.3 “Lightbulb Sun” bugfix release

Bug fixes

fix a possible out-of-bound access in the CGI handling. It was introduced last October during a refactoring, but due to how many malloc(3) implementations works this hasn't been found until now. Otto' malloc is more strict fortunately.

2022/03/26 - 1.8.2 “Lightbulb Sun” bugfix release

Bug fixes

fix a CGI timing issue: if a connection handled by a CGI scripts is interrupted with the right timing it causes the server process to exit with "fatal in client_by_id: invalid id X".

New Features

add a new block `type { ... }' to define mime types mapping.

Improvements

use shell built-in `command' instead of which(1), prodded by cage and Allen Sobot.
configure script: allow to set MANDIR from cmdline (Allen Sobot)
add systemd-sysusers sample file in contrib/ (Nakaya)
[linux/seccomp] allow fstatat64(2), llseek(2) and sigreturn(2), needed by glibc on armv7. (Tobias Berger)
[linux/seccomp] tightens rules by allowing openat(2) only with the O_RDONLY flag.

2022/02/10 - 1.8.1 “Lightbulb Sun” bugfix release

Bug fixes

fix landlock usage on linux: don't assume that access capabilities not listed are implicitly denied, because they are not. Mickaël Salaün, the landlock author, found the same error on game of trees:

In a nutshell, the ruleset's handled_access_fs is required for backward and forward compatibility (i.e. the kernel and user space may not know each other's supported restrictions), hence the need to be explicit about the denied-by-default access rights.

In practice this affects only linux and only partially: thanks to the design of the daemon and the seccomp filter the effects of this mistake in handling landlock are fortunately limited. However, in theory at least, gmid could be for e.g. tricked into truncating existing files, so it's highly suggested to update.

Improvements

All by Anna “CyberTailor”, thanks!

don't skip unit tests when SKIP_RUNTIME_TEST is set
add `gg' to the regress target dependencies
fix the "implicit declaration of asprintf" warning
sync vim syntax

2022/01/30 - 1.8 “Lightbulb Sun”

New Features

reverse proxying support: gmid now can relay gemini requests to other hosts.
install gg too: it's a simple gemini client ("gemini get") initially developed as part of the regression suite.
added OCSP stapling support (by @The-King-of-Toasters, thanks!)
add gencert, a simple script to generate self-signed certs.
add renew-certs, a script to automatically renew self-signed certs.
multiple -n partially dump the parsed configuration.

Improvements

reworked the fastcgi subsystem, now it's completely asynchronous.
refactored the internal of the server too.
refactored the regression suite (in particular reduced the timeout for single tests from 30 to 10 seconds.)
configure: add support for --prefix=... autoconf-style flag.
relax the "wont proxy" check: don't check that the port in the request is the same we're listening on. Suggested and discussed with Allen Sobot, thanks!
relax the strict ordering of options, locations and proxy blocks inside a server block.

Bug fixes

don't pass through illegal replies from CGI scripts.
fix the "double slash" error in logs.
fix the configure for cross-compilation: don't run the test binaries just built. Suggested by Nikolay Korotkiy (@sikmir), thanks!
(seccomp) allow ugetrlimit(2), needed by glibc on arm7l. By Max, thanks!

2021/10/15 - 1.7.5 “Space-dye Vest” fifth bugfix release

This version includes the following bugfix

don’t die when a connection is closed before being accepted by gmid (i.e. handle ‘ECONNRESET’)

2021/09/24 - 1.7.4 “Space-dye Vest” fourth bugfix release

This version includes the following bugfix:

fix a possible out-of-bound access when handling a request for a non-existent file in the root directory of a vhost that's matched by the cgi option

and the relative regression test.

2021/09/19 - 1.7.3 “Space-dye Vest” third bugfix release

Improvements

follows symlinks
improved documentation and added key generation example (thanks! Anna)

Bugfix

fix syslog logging on FreeBSD. Reported by Karl Jeacle, thanks!
don't crash if ``-c'' is missing in configtest mode (-n). Reported by heph, thanks!
allow fstat64 on linux (needed by glibc on aarch64). Reported by pine, thanks!

2021/07/19 - 1.7.2 “Space-dye Vest” second bugfix release

This version incudes the following bugfix:

an un-initialized field in the configless code path leads to a crash on the first request.

and the relative regression test.

2021/07/11 - 1.7.1 “Space-dye Vest” bugfix release

This version includes two bugfixes:

use ${MAKE} to recursively call make.
fix the misleading example in the manpage: macros may not be reserved words

2021/07/10 - 1.7 “Space-dye Vest”

Starting from this version gmid doesn't depend on lex anymore, but yacc is still needed.

New features

initial fastcgi support! (it's still young!)
added user-defined macros, either via ‘-Dname=val’ or directly in the configuration file.
new ‘include’ keyword to load additional configuration files.
new ‘env’ rule to define environment vars for CGI scripts.
new ‘alias’ rule to define hostname aliases for a server.
allow ‘root’ to be specified per-location block.
pidfile support with the new ‘-P’ cli flag.
define ‘TLS_1.8.3ION’, ‘TLS_CIPHER’ and ‘TLS_CIPHER_STRENGTH’ for CGI scripts.

Improvements

remove limits on the number of virtual hosts and location blocks that can be defined.
print the datetime when logging to stderr.
use ‘text/x-patch’ for ‘.patch’ and ‘.diff’ files.
sort the auto index alphabetically.
various improvements to the log management.
drop the dependency on lex.
added ‘--help’ as synonym of ‘-h’ and ‘-V’/‘--version‘ to print the version.
c-like handling of strings in the configuration file: when two or more strings are next to each-others, are automatically joined into a single string. This is particularly useful with $-macros.

Bug fixes

correctly handle CGI scripts that replies with the maxium header length allowed.
fixed the static target.
fixed recursive mkdirs for configless mode (i.e. create ‘~/.local/share/gmid’)
logs sent to syslog now have proper priority (before every message ended up as LOG_CRIT). Found by Anna “CyberTailor”, thanks!
ensure ‘%p’ (path) is always absolute in ‘block return’ rules.
fix automatic certificate generation, it caused problems on some adroid devices. Found by Gnuserland, thanks!
document the ‘log’ rule.
the seccomp filter was reworked and now it's known to work properly on a vast range of architectures (to be more specific: all the architectures supported by alpine linux), see github issue #4. Prompted and tested by @begss, thanks!
various improvements to the configure script, notified and fixed by Anna “CyberTailor”, thanks!
added a timeout to the regression tests.

Breaking changes

if duplicate rules are found in the configuration file, an error is now raised instead of silently using only the last value.
(sort of) ‘gg’ moved to ‘regress’ as it's only used in the regression suite.
(notice) the “mime "mime-type" "extension"” rule was deprecated and replaced by the new “map "mime-type" to-ext "extension"”. The ‘mime’ rule will be removed in a future version because its syntax is incompatible with the new string auto-concat mechanism.
