name and nlen parameters passed to ->strategy hook are unused, remove them. In general ->strategy hook should know what it's doing, and don't do something tricky for which, say, pointer to original userspace array may be needed (name).

2008-10-15IPV6: Fix default gateway criteria wrt. HIGH/LOW preference radv optionPedro Ribeiro
Problem observed: In IPv6, in the presence of multiple routers candidates to default gateway in one segment, each sending a different value of preference, the Linux hosts connected to the segment weren't selecting the right one in all the combinations possible of LOW/MEDIUM/HIGH preference. This patch changes two files: include/linux/icmpv6.h Get the "router_pref" bitfield in the right place (as RFC4191 says), named the bit left with this fix as "home_agent" (RFC3775 say that's his function) net/ipv6/ndisc.c Corrects the binary logic behind the updating of the router preference in the flags of the routing table Result: With this two fixes applied, the default route used by the system was to consistent with the rules mentioned in RFC4191 in case of changes in the value of preference in router advertisements Signed-off-by: Pedro Ribeiro <pribeiro@net.ipl.pt> Acked-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S.

2008-10-15ath9k/mac80211: disallow fragmentation in ath9k, report to userspaceJohannes Berg
As I've reported, ath9k currently fails utterly when fragmentation is enabled. This makes ath9k "support" hardware fragmentation by not supporting fragmentation at all to avoid the double-free issue. The patch also changes mac80211 to report errors from the driver operation to userspace. That hack in ath9k should be removed once the rate control algorithm it has is fixed, and we can at that time consider removing the hw fragmentation support entirely since it's not used by any driver.

2008-10-14netfilter: ctnetlink: remove bogus module dependency between ctnetlink and ↵Pablo Neira Ayuso
nf_nat This patch removes the module dependency between ctnetlink and nf_nat by means of an indirect call that is initialized when nf_nat is loaded. Now, nf_conntrack_netlink only requires nf_conntrack and nfnetlink. This patch puts nfnetlink_parse_nat_setup_hook into the nf_conntrack_core to avoid dependencies between ctnetlink, nf_conntrack_ipv4 and nf_conntrack_ipv6. This patch also introduces the function ctnetlink_change_nat that is only invoked from the creation path. Actually, the nat handling cannot be invoked from the update path since this is not allowed. By introducing this function, we remove the useless nat handling in the update path and we avoid deadlock-prone code. This patch also adds the required EAGAIN logic for nfnetlink.

2008-10-14netfilter: restore lost #ifdef guarding defrag exceptionPatrick McHardy
Nir Tzachar <nir.tzachar@gmail.com> reported a warning when sending fragments over loopback with NAT: [ 6658.338121] WARNING: at net/ipv4/netfilter/nf_nat_standalone.c:89 nf_nat_fn+0x33/0x155() The reason is that defragmentation is skipped for already tracked connections. This is wrong in combination with NAT and ip_conntrack actually had some ifdefs to avoid this behaviour when NAT is compiled in. The entire "optimization" may seem a bit silly, for now simply restoring the lost #ifdef is the easiest solution until we can come up with something better.

2008-10-10netlabel: Replace protocol/NetLabel linking with refrerence countsPaul Moore
NetLabel has always had a list of backpointers in the CIPSO DOI definition structure which pointed to the NetLabel LSM domain mapping structures which referenced the CIPSO DOI struct. The rationale for this was that when an administrator removed a CIPSO DOI from the system all of the associated NetLabel LSM domain mappings should be removed as well; a list of backpointers made this a simple operation. Unfortunately, while the backpointers did make the removal easier they were a bit of a mess from an implementation point of view which was making further development difficult. Since the removal of a CIPSO DOI is a realtively rare event it seems to make sense to remove this backpointer list as the optimization was hurting us more then it was helping. However, we still need to be able to track when a CIPSO DOI definition is being used so replace the backpointer list with a reference count. In order to preserve the current functionality of removing the associated LSM domain mappings when a CIPSO DOI is removed we walk the LSM domain mapping table, removing the relevant entries.
