2012-06-27netlink: Get rid of obsolete rtnetlink macrosThomas Graf
Removes all RTA_GET*() and RTA_PUT*() variations, as well as the the unused rtattr_strcmp(). Get rid of rtm_get_table() by moving it to its only user decnet. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

2012-06-27ipv4: tcp: dont cache unconfirmed intput dstEric Dumazet
DDOS synflood attacks hit badly IP route cache. On typical machines, this cache is allowed to hold up to 8 Millions dst entries, 256 bytes for each, for a total of 2GB of memory. rt_garbage_collect() triggers and tries to cleanup things. Eventually route cache is disabled but machine is under fire and might OOM and crash. This patch exploits the new TCP early demux, to set a nocache boolean in case incoming TCP frame is for a not yet ESTABLISHED or TIMEWAIT socket. This 'nocache' boolean is then used in case dst entry is not found in route cache, to create an unhashed dst entry (DST_NOCACHE) SYN-cookie-ACK sent use a similar mechanism (ipv4: tcp: dont cache output dst for syncookies), so after this patch, a machine is able to absorb a DDOS synflood attack without polluting its IP route cache.

2012-06-27mac80211: correct behaviour on unrecognised action framesJohannes Berg
When receiving an "individually addressed" action frame, the receiver is required to return it to the sender. mac80211 gets this wrong as it also returns group addressed (mcast) frames to the sender. Fix this and update the reference to the new 802.11 standards version since things were shuffled around significantly.

2012-06-27netfilter: nf_conntrack: fix memory leak if sysctl registration failsGao feng
In nf_ct_l4proto_register_sysctl, if l4proto sysctl registration fails, we have to make sure that we release the compat sysctl table.

2012-06-27netfilter: nf_conntrack: use l4proto->users as refcount for per-net dataGao feng
Currently, nf_proto_net's l4proto->users meaning is quite confusing since it depends on the compilation tweaks. To resolve this, we cleanup this code to regard it as the refcount for l4proto's per-net data, since there may be two l4protos use the same per-net data. Thus, we increment pn->users when nf_conntrack_l4proto_register successfully, and decrement it for nf_conntrack_l4_unregister case. The users refcnt is not required form layer 3 protocol trackers.

2012-06-27netfilter: nf_conntrack: fix nf_conntrack_l3proto_registerGao feng
Before commit 2c352f444ccfa966a1aa4fd8e9ee29381c467448 (netfilter: nf_conntrack: prepare namespace support for l4 protocol trackers), we register sysctl before register protocol tracker. Thus, if sysctl is registration fails, the protocol tracker will not be registered. After that commit, if sysctl registration fails, protocol registration still remains, so we leave things in intermediate state. To fix this, this patch registers sysctl before protocols. And if protocol registration fail, sysctl is unregistered. Signed-off-by: Gao feng <gaofeng@cn.fujitsu.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2012-06-27cfg80211: don't allow WoWLAN support without CONFIG_PMJohannes Berg
When CONFIG_PM is disabled, no device can possibly support WoWLAN since it can't go to sleep to start with. Due to this, mac80211 had even rejected the hardware registration. By making all the code and data for WoWLAN depend on CONFIG_PM we can promote this runtime error to a compile-time error. Add #ifdef around all WoWLAN code to remove it in systems that don't need it as they never suspend.

This patch takes care of statistics using atomic_long in both RX and TX paths, and fix a bug in l2tp_eth_dev_recv(), which was caching skb->data before a pskb_may_pull() call.

2012-06-26ipv4: Cache ip_error() routes even when not forwarding.David S. Miller
And account for the fact that, when we are not forwarding, we should bump statistic counters rather than emit an ICMP response. RP-filter rejected lookups are still not cached. Since -EHOSTUNREACH and -ENETUNREACH can now no longer be seen in ip_rcv_finish(), remove those checks. Signed-off-by: David S. Miller <davem@davemloft.net>

git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid Pull HID fixes from Jiri Kosina: "The most important one is a purification of Kconfig for CONFIG_HID; the inclusion of HID groups and autoloading didn't leave the Kconfig in a really consistent state. Henrik's patch fixes that. In addition to that, there are two small fixes for logitech and magicmouse drivers." * 'upstream-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid: HID: Fix the generic Kconfig options HID: magicmouse: Correct report range of major / minor axes HID: logitech: don't use stack based dj_report structures
