* libalias: Style cleanupLutz Donnerhacke2021-05-291-139/+114
| | | | | | | | | | | | | | | | | | | | | | | | | | libalias is a convolut of various coding styles modified by a series of different editors enforcing interesting convetions on spacing and comments. This patch is a baseline to start with a perfomance rework of libalias. Upcoming patches should be focus on the code, not on the style. That's why most annoying style errors should be fixed beforehand.

* sys: general adoption of SPDX licensing ID tags.Pedro F. Giffuni2017-11-271-0/+2
| | | | | | | | | | | | | | | | | Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. No functional change intended.

* Use inet_ntoa_r() instead of inet_ntoa() throughout the kernelEric van Gyzen2017-02-161-8/+24
| | | | | | | | | | | | | | | inet_ntoa() cannot be used safely in a multithreaded environment because it uses a static local buffer. Instead, use inet_ntoa_r() with a buffer on the caller's stack.

* Summer of Code 2005: improve libalias - part 1 of 2Paolo Pisati2006-09-261-9/+129
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the first part of my previous Summer of Code work, we get: -made libalias modular: -support for 'particular' protocols (like ftp/irc/etcetc) is no more hardcoded inside libalias, but it's available through external modules loadable at runtime -modules are available both in kernel (/boot/kernel/alias_*.ko) and user land (/lib/libalias_*) -protocols/applications modularized are: cuseeme, ftp, irc, nbt, pptp, skinny and smedia -added logging support for kernel side -cleanup After a buildworld, do a 'mergemaster -i' to install the file libalias.conf in /etc or manually copy it. During startup (and after every HUP signal) user land applications running the new libalias will try to read a file in /etc called libalias.conf: that file contains the list of modules to load. User land applications affected by this commit are ppp and natd: if libalias.conf is present in /etc you won't notice any difference. The only kernel land bit affected by this commit is ng_nat: if you are using ng_nat, and it doesn't correctly handle ftp/irc/etcetc sessions anymore, remember to kldload the correspondent module (i.e. kldload alias_ftp). General information and details about the inner working are available in the libalias man page under the section 'MODULAR ARCHITECTURE (AND ipfw(4) SUPPORT)'. NOTA BENE: this commit affects _ONLY_ libalias, ipfw in-kernel nat support will be part of the next libalias-related commit.
