* Summer of Code 2005: improve libalias - part 1 of 2Paolo Pisati2006-09-2612-13/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* natd core dumps when -reverse switch is used because of a bug inPoul-Henning Kamp2005-04-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | libalias. In /usr/src/lib/libalias/alias.c, the functions LibAliasIn and LibAliasOutTry call the legacy PacketAliasIn/PacketAliasOut instead of LibAliasIn/LibAliasOut when the PKT_ALIAS_REVERSE option is set. In this case, the context variable "la" gets lost because the legacy compatibility routines expect "la" to be global. This was obviously an oversight when rewriting the PacketAlias* functions to the LibAlias* functions. The fix (as shown in the patch below) is to remove the legacy subroutine calls and replace with the new ones using the "la" struct as the first arg.
