When terminating DSL connections for an assortment of random customers, I've found it necessary to use iptables to clamp the MSS used for connections to work around the various ICMP blackholes in the greater net. Unfortunately, the current behaviour in Linux is imperfect and actually make things worse, so I'm proposing the following: increasing the MSS in a packet can never be a good thing, so make --set-mss only lower the MSS in a packet. Yes, I am aware of --clamp-mss-to-pmtu, but it doesn't work for outgoing connections from clients (ie web traffic), as it only looks at the PMTU on the destination route, not the source of the packet (the DSL interfaces in question have a 1442 byte MTU while the destination ethernet interface is 1500 -- there are problematic hosts which use a 1300 byte MTU). Reworking that is probably a good idea at some point, but it's more work than this is. Signed-off-by:

Reformat ip_tables.c and ip6_tables.c in order to eliminate non-functional differences and minimize diff output. This allows to get a view of the real differences using: sed -e 's/IP6T/IPT/g' \ -e 's/IP6/IP/g' \ -e 's/INET6/INET/g' \ -e 's/ip6t/ipt/g' \ -e 's/ip6/ip/g' \ -e 's/ipv6/ip/g' \ -e 's/icmp6/icmp/g' \ net/ipv6/netfilter/ip6_tables.c | \ diff -wup /dev/stdin net/ipv4/netfilter/ip_tables.c Signed-off-by: -

Old userspace doesn't support revision 1, especially for IPv6, which is only available in the SVN snapshot. Add compat support for revision 0. Signed-off-by:

Use compat types and compat iterators when dealing with compat entries for clarity. This doesn't actually make a difference for ip_tables, but is needed for ip6_tables and arp_tables. Signed-off-by:

Account for size differences when dumping entries or calculating the entry positions. This doesn't actually make any difference for IPv4 since the structures have the same size, but its logically correct and needed for IPv6. Signed-off-by:

These drivers pass full mactime information to the stack, make them indicate this via the new RX_FLAG_TSFT to get mac80211 to show this information in monitor mode. Signed-off-by:

Introduce scan capabilities to WEXT so that userspace can do intelligent things with scan behavior such as handling hidden SSIDs more gracefully. If the driver reports a specific scan capability, the driver must respect the options specified in the iw_scan_req structure when handling the SIOCSIWSCAN call, unless it's mode or state does not allow it to do so, in which case it must return an error. This version switches to Dave Kilroy's suggestion of claiming unused padding space for the scan_capa field. Signed-off-by:

This implements the changes to the nofeedback timer handling suggested in draft rfc3448bis00, section 4.4. In particular, these changes mean: * better handling of the lossless case (p == 0) * the timestamp for computing t_ld becomes obsolete * much more recent document (RFC 3448 is almost 5 years old) * concepts in rfc3448bis arose from a real, working implementation (cf. sec. 12) Signed-off-by:
