2013-10-03tcp: shrink tcp6_timewait_sock by one cache lineEric Dumazet4-7/+12
While working on tcp listener refactoring, I found that it would really make things easier if sock_common could include the IPv6 addresses needed in the lookups, instead of doing very complex games to get their values (depending on sock being SYN_RECV, ESTABLISHED, TIME_WAIT) For this to happen, I need to be sure that tcp6_timewait_sock and tcp_timewait_sock consume same number of cache lines. This is possible if we only use 32bits for tw_ttd, as we remove one 32bit hole in inet_timewait_sock inet_tw_time_stamp() is defined and used, even if its current implementation looks like tcp_time_stamp : We might need finer resolution for tcp_time_stamp in the future. Before patch : sizeof(struct tcp6_timewait_sock) = 0xc8 After patch : sizeof(struct tcp6_timewait_sock) = 0xc0 Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2013-10-03atl1e: enable support for NETIF_F_RXALL and NETIF_F_RXCRC featuresAndrea Merello1-4/+42
This patch allows (optionally, via ethtool) the atl1e NIC to: - Receive bad frames (runt, bad-fcs, etc..) - Receive full frames without stripping the FCS. This has been tested on my board by injecting runt and bad-fcs frames with a FPGA-based device. The particular scenario of receiving very short frames (<4 bytes) without passing FCS to the upper layer has been also tested: This could be potentially dangerous because the driver performs a 4 byte subtraction on the frame length, but I finally have NOT added anything to avoid this because it seems the NIC always discards frames so much short.. If someone still have some reason to worry about this, please tell me.. I will add an explicit SW check.. Signed-off-by: Andrea Merello <andrea.merello@gmail.com> Signed-off-by: David S.

2013-10-03bonding: modify the old and add new xmit hash policiesNikolay Aleksandrov5-134/+72
This patch adds two new hash policy modes which use skb_flow_dissect: 3 - Encapsulated layer 2+3 4 - Encapsulated layer 3+4 There should be a good improvement for tunnel users in those modes. It also changes the old hash functions to: hash ^= (__force u32)flow.dst ^ (__force u32)flow.src; hash ^= (hash >> 16); hash ^= (hash >> 8); Where hash will be initialized either to L2 hash, that is SRCMAC[5] XOR DSTMAC[5], or to flow->ports which should be extracted from the upper layer. Flow's dst and src are also extracted based on the xmit policy either directly from the buffer or by using skb_flow_dissect, but in both cases if the protocol is IPv6 then dst and src are obtained by ipv6_addr_hash() on the real addresses. In case of a non-dissectable packet, the algorithms fall back to L2 hashing. The bond_set_mode_ops() function is now obsolete and thus deleted because it was used only to set the proper hash policy. Also we trim a pointer from struct bonding because we no longer need to keep the hash function, now there's only a single hash function - bond_xmit_hash that works based on bond->params.xmit_policy. The hash function and skb_flow_dissect were suggested by Eric Dumazet. The layer names were suggested by Andy Gospodarek, because I suck at semantics.

2013-10-03inet: consolidate INET_TW_MATCHEric Dumazet7-40/+21
TCP listener refactoring, part 2 : We can use a generic lookup, sockets being in whatever state, if we are sure all relevant fields are at the same place in all socket types (ESTABLISH, TIME_WAIT, SYN_RECV) This patch removes these macros : inet_addrpair, inet_addrpair, tw_addrpair, tw_portpair And adds : sk_portpair, sk_addrpair, sk_daddr, sk_rcv_saddr Then, INET_TW_MATCH() is really the same than INET_MATCH() Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

2013-10-03Bluetooth: Only one command per L2CAP LE signalling is supportedMarcel Holtmann1-25/+19
The Bluetooth specification makes it clear that only one command should be present in the L2CAP LE signalling packet. So tighten the checks here and restrict it to exactly one command. This is different from L2CAP BR/EDR signalling where multiple commands can be part of the same packet.

2013-10-03Bluetooth: Check minimum length of SMP packetsMarcel Holtmann1-2/+7
When SMP packets are received, make sure they contain at least 1 byte header for the opcode. If not, drop the packet and disconnect the link. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-03Bluetooth: Drop packets on ATT fixed channel on BR/EDRMarcel Holtmann1-0/+4
The ATT fixed channel is only valid when using LE connections. On BR/EDR it is required to go through L2CAP connection oriented channel for ATT. Drop ATT packets when they are received on a BR/EDR connection. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-03Bluetooth: L2CAP connectionless channels are only valid for BR/EDRMarcel Holtmann1-0/+4
When receiving connectionless packets on a LE connection, just drop the packet. There is no concept of connectionless channels for LE. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

2013-10-03Bluetooth: Don't copy L2CAP LE signalling to raw socketsMarcel Holtmann1-2/+0
The L2CAP raw sockets are only used for BR/EDR signalling. Packets on LE links should not be forwarded there. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>

2013-10-03Bluetooth: Allow changing device class when BR/EDR is disabledMarcel Holtmann1-1/+1
Changing the device class when BR/EDR is disabled has no visible effect for remote devices. However to simplify the logic allow it as long as the controller supports BR/EDR operations. If it is not allowed, then the overall logic becomes rather complicated since the class of device values would need clearing or restoring when BR/EDR setting changes.

2013-10-03Bluetooth: Restrict loading of long term keys to LE capable controllersMarcel Holtmann1-0/+6
Loading long term keys into a BR/EDR only controller make no sense. The kernel would never use any of these keys. So instead of allowing userspace to waste memory, reject such operation with a not supported error message.

2013-10-03Bluetooth: Allow setting static address even if LE is disabledMarcel Holtmann1-4/+2
Setting the static address does not depend on LE beeing enabled. It only depends on a controller with LE support. When depending on LE enabled this command becomes really complicated since in case LE gets disabled, it would be required to clear the static address and also its random address representation inside the controller. With future support for private addresses such complex setup should be avoided. Signed-off-by: Marcel Holtmann <marcel@holtmann.org> Signed-off-by: Johan Hedberg <johan.hedberg@intel.com>
2013-10-03Bluetooth: Restrict SSP setting changes to BR/EDR enabled controllersMarcel Holtmann1-1/+5
Only when BR/EDR is supported and enabled, allow changing of the SSP setting. Just checking if the hardware supports SSP is not enough since it might be the case that BR/EDR is disabled. In the case that BR/EDR is disabled, but SSP supported by the controller the not supported error message is now returned.
