* net/key/af_key.c: add range checks on ->sadb_x_policy_lenDan Carpenter2012-10-011-0/+3
| | | | | | | | | | | | | | Because sizeof() is size_t then if "len" is negative, it counts as a large positive value. The call tree looks like: pfkey_sendmsg() -> pfkey_process() -> pfkey_spdadd() -> parse_ipsecrequests() Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: David S.

* ipv4: gre: add GRO capabilityEric Dumazet2012-10-011-2/+11
| | | | | | | | | | | Add GRO capability to IPv4 GRE tunnels, using the gro_cells infrastructure. Tested using IPv4 and IPv6 TCP traffic inside this tunnel, and checking GRO is building large packets. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

* net: add gro_cells infrastructureEric Dumazet2012-10-011-0/+2
| | | | | | | | | | | | | | | | | | | | | | This adds a new include file (include/net/gro_cells.h), to bring GRO (Generic Receive Offload) capability to tunnels, in a modular way. Because tunnels receive path is lockless, and GRO adds a serialization using a napi_struct, I chose to add an array of up to DEFAULT_MAX_NUM_RSS_QUEUES cells, so that multi queue devices wont be slowed down because of GRO layer. skb_get_rx_queue() is used as selector. In the future, we might add optional fanout capabilities, using rxhash for example. With help from Ben Hutchings who reminded me netif_get_num_default_rss_queues() function.

* tcp: gro: add checksuming helpersEric Dumazet2012-10-012-6/+33
| | | | | | | | | | | | | | skb with CHECKSUM_NONE cant currently be handled by GRO, and we notice this deep in GRO stack in tcp[46]_gro_receive() But there are cases where GRO can be a benefit, even with a lack of checksums. This preliminary work is needed to add GRO support to tunnels. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* ipv6: del unreachable route when an addr is deleted on loNicolas Dichtel2012-10-011-2/+8
| | | | | | | | | | | | | | | | | When an address is added on loopback (ip -6 a a 2002::1/128 dev lo), two routes are added: - one in the local table: local 2002::1 via :: dev lo proto none metric 0 - one the in main table (for the prefix): unreachable 2002::1 dev lo proto kernel metric 256 error -101 When the address is deleted, the route inserted in the main table remains because we use rt6_lookup(), which returns NULL when dst->error is set, which is the case here! Thus, it is better to use ip6_route_lookup() to avoid this kind of filter. Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for socket of type SOCK_RAW to LLCP. sk_buff are copied and sent to raw sockets with a 2 bytes extra header: The first byte header contains the nfc adapter index. The second one contains flags: - 0x01 - Direction (0=RX, 1=TX) - 0x02-0x80 - Reserved A raw socket has to be explicitly bound to a nfc adapter. This is achieved by specifying the adapter index to be bound to in the dev_idx field of the sockaddr_nfc_llcp struct passed to bind().

| | | * cfg80211: Fix regulatory check for 60GHz band frequenciesVladimir Kondratiev2012-09-251-5/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current regulatory code on cfg80211 performs a check to see if a regulatory rule belongs to an IEEE band so that if a Country IE is received and no rules are specified for a band (which is allowed by IEEE) those bands are left intact. The current band check assumes a rule is bound to a band if the rule's start or end frequency is less than 2 GHz apart from the center of frequency being inspected. In order to support 60 GHz for 802.11ad we need to increase this to account for the channel spacing of 2160 MHz whereby a channel somewhere in the middle of a regulatory rule may be more than 2 GHz apart from either the beginning or end of the frequency rule. Without a fix for this even though channels 1-3 are allowed world wide on the rule (57240 - 63720 @ 2160), channel 2 at 60480 MHz will end up getting disabled given that it is 3240 MHz from both the frequency rule start and end frequency. Fix this by using 2 GHz separation assumption for the 2.4 and 5 GHz bands but for 60 GHz use a 10 GHz separation before assuming a rule is not part of the band. Since we have no 802.11ad drivers yet merged this change has no impact to existing Linux upstream device drivers. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Acked-by: Luis R.

| | * | NFC: Remove crc generation from shdlc layerWaldemar Rymarkiewicz2012-09-251-25/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Checksum is specific for a chip spcification and it varies (in size and type) between different hardware. It should be handled in the driver then. Moreover, shdlc spec doesn't mention crc as a part of the frame. Update pn544_hci driver as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NFC is using a number of custom ordered workqueues w/ WQ_MEM_RECLAIM. WQ_MEM_RECLAIM is unnecessary unless NFC is gonna be used as transport for storage device, and all use cases match one work item to one ordered workqueue - IOW, there's no actual ordering going on at all and using system_nrt_wq gives the same behavior. There's nothing to be gained by using custom workqueues. Use system_nrt_wq instead and drop all the custom ones.

The increment should only happen once per kernel release and not for every command/event that gets added. The revision value is for informational purposes only, but this simple policy would make any future debugging a lot simple.
