* Summer of Code 2005: improve libalias - part 1 of 2Paolo Pisati2006-09-261-4/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Disable checksum processing in LibAlias, when it works as aGleb Smirnoff2005-06-271-0/+4
| | | | | | | | | | | | | | | | | | kernel module. LibAlias is not aware about checksum offloading, so the caller should provide checksum calculation. (The only current consumer is ng_nat(4)). When TCP packet internals has been changed and it requires checksum recalculation, a cookie is set in th_x2 field of TCP packet, to inform caller that it needs to recalculate checksum. This ugly hack would be removed when LibAlias is made more kernel friendly. Incremental checksum updates are left as is, since they don't conflict with offloading.

| | | | | | | | | | {ip,udp,tcp} header and return a void * pointing to the payload (i.e. the first byte past the end of the header and any required padding). Use them consistently throughout libalias to a) reduce code duplication, b) improve code legibility, c) get rid of a bunch of alignment warnings. Notes: svn path=/head/; revision=131699

I was hoping WARNS?=6 might reveal more serious problems, and perhaps the source of the -O2 breakage, but found no smoking gun. Notes: svn path=/head/; revision=131614

* Mostly mechanical rework of libalias:Poul-Henning Kamp2004-01-171-2/+3
| | | | | | | | | | | | | | | Makes it possible to have multiple packet aliasing instances in a single process by moving all static and global variables into an instance structure called "struct libalias". Redefine a new API based on s/PacketAlias/LibAlias/g Add new "instance" argument to all functions in the new API. Implement old API in terms of the new API. Notes: svn path=/head/; revision=124621
