Gleb Smirnoff 5c39f7bdeb Bunch of fixes to pfsync(4) module load/unload: ... o Make the pfsync.ko actually usable. Before this change loading it didn't register protosw, so was a nop. However, a module /boot/kernel did confused users. o Rewrite the way we are joining multicast group: - Move multicast initialization/destruction to separate functions. - Don't allocate memory if we aren't going to join a multicast group. - Use modern API for joining/leaving multicast group. - Now the utterly wrong pfsync_ifdetach() isn't needed. o Move module initialization from SYSINIT(9) to moduledata_t method. o Refuse to unload module, unless asked forcibly. o Improve a bit some FreeBSD porting code: - Use separate malloc type. - Simplify swi sheduling. This change is probably wrong from VIMAGE viewpoint, however pfsync wasn't VIMAGE-correct before this change, too. Glanced at by: bz		2012-01-09 08:50:22 +00:00
