Kernel Changes

This is a summary of the main changes in the kernel that diverge from mainline.

  • added net/netfilter/xt_qtaguid*
  • imported then modified net/netfilter/xt_quota2.c from xtables-addons project
  • fixes in net/netfilter/ip6_tables.c
  • modified ip*t_REJECT.c
  • modified net/netfilter/xt_socket.c

A few comments on the kernel configuration:

  • xt_qtaguid masquerades as xt_owner and relies on xt_socket and itself relies on the connection tracker.
  • The connection tracker can't handle large SIP packets, it must be disabled.
  • The modified xt_quota2 uses the NFLOG support to notify userspace.
