* net: refactor tcp splice receive path to improve readabilityOctavian Purdila2008-07-15
| | | | | | | | | | | | | | | - move all of the details on offsets, lengths and buffers into a single function instead of doing these operation from multiple places - use a bottom up approach: try to avoid details in the high level functions, introduce them gradually as we go deeper in the function call stack With helpful feedback from Jarek Poplawski.

* netdev: Do not use TX lock to protect address lists.David S. Miller2008-07-15
| | | | | | | | | Now that we have a specific lock to protect the network device unicast and multicast lists, remove extraneous grabs of the TX lock in cases where the code only needs address list protection. Signed-off-by: David S. Miller <davem@davemloft.net>
* netdev: Add netdev->addr_list_lock protection.David S. Miller2008-07-15
| | | | | | | | | | | | | Add netif_addr_{lock,unlock}{,_bh}() helpers. Use them to protect operations that operate on or read the network device unicast and multicast address lists. Also use them in cases where the code simply wants to block calls into the driver's ->set_rx_mode() and ->set_multicast_list() methods. Signed-off-by: David S. Miller <davem@davemloft.net>
* netdev: Add addr_list_lock to struct net_device.David S. Miller2008-07-15

* inet: toss struct net initialization aroundPavel Emelyanov2008-07-15
| | | | | | | | | | | | | Some places, that deal with ICMP statistics already have where to get a struct net from, but use it directly, without declaring a separate variable on the stack. Since I will need this net soon, I declare a struct net on the stack and use it in the existing places in a separate patch not to spoil the future ones.

* packet: support extensible, 64 bit clean mmaped ring structurePatrick McHardy2008-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | The tpacket_hdr is not 64 bit clean due to use of an unsigned long and can't be extended because the following struct sockaddr_ll needs to be at a fixed offset. Add support for a version 2 tpacket protocol that removes these limitations. Userspace can query the header size through a new getsockopt option and change the protocol version through a setsockopt option. The changes needed to switch to the new protocol version are: 1. replace struct tpacket_hdr by struct tpacket2_hdr 2. query header len and save 3. set protocol version to 2 - set up ring as usual 4. for getting the sockaddr_ll, use (void *)hdr + TPACKET_ALIGN(hdrlen) instead of (void *)hdr + TPACKET_ALIGN(sizeof(struct tpacket_hdr)) Steps 2 and 4 can be omitted if the struct sockaddr_ll isn't needed.

* vlan: deliver packets received with VLAN acceleration to network tapsPatrick McHardy2008-07-15
| | | | | | | | | | | | | | When VLAN header stripping is used, packets currently bypass packet sockets (and other network taps) completely. For locally existing VLANs, they appear directly on the VLAN device, for unknown VLANs they are silently dropped. Add a new function netif_nit_deliver() to deliver incoming packets to all network interface taps and use it in __vlan_hwaccel_rx() to make VLAN packets visible on the underlying device.

* vlan: Don't store VLAN tag in cbPatrick McHardy2008-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use a real skb member to store the skb to avoid clashes with qdiscs, which are allowed to use the cb area themselves. As currently only real devices that consume the skb set the NETIF_F_HW_VLAN_TX flag, no explicit invalidation is neccessary. The new member fills a hole on 64 bit, the skb layout changes from: __u32 mark; /* 172 4 */ sk_buff_data_t transport_header; /* 176 4 */ sk_buff_data_t network_header; /* 180 4 */ sk_buff_data_t mac_header; /* 184 4 */ sk_buff_data_t tail; /* 188 4 */ /* --- cacheline 3 boundary (192 bytes) --- */ sk_buff_data_t end; /* 192 4 */ /* XXX 4 bytes hole, try to pack */ to __u32 mark; /* 172 4 */ __u16 vlan_tci; /* 176 2 */ /* XXX 2 bytes hole, try to pack */ sk_buff_data_t transport_header; /* 180 4 */ sk_buff_data_t network_header; /* 184 4 */ Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

* tipc: Optimization to multicast name lookup algorithmAllan Stephens2008-07-15
| | | | | | | | | | | | | | | This patch simplifies and speeds up TIPC's algorithm for identifying on-node and off-node destinations that overlap a multicast name sequence range. Rather than traversing the list of all known name publications within the cluster, it now traverses the (potentially much shorter) list of name publications made by the node itself, and determines if any off-node destinations exist by comparing the sizes of the two lists. (Since the node list must be a subset of the cluster list, a difference in sizes means that at least one off-node destination must exist.)

* tipc: Add missing locks when inspecting node list & link listAllan Stephens2008-07-15
| | | | | | | | | | This patch ensures that TIPC configuration commands that display info about neighboring nodes and their links take the spinlocks that protect the node list and link lists from changing while the lists are being traversed.

* tipc: Fix bug in scope checking for multicast messagesAllan Stephens2008-07-15
| | | | | | | | | | | | | This patch ensures that TIPC's multicast message name lookup algorithm does individualized scope checking for each published name it examines. Previously, scope checking was only done for the first name in a name table publication list, which could result in incoming multicast messages being delivered to ports publishing names with "node" scope, or not being delivered to ports publishing names with "cluster" or "zone" scope.

* tipc: Eliminate improper use of TIPC_OK error codeAllan Stephens2008-07-15
| | | | | | | | | | | This patch corrects many places where TIPC routines indicated successful completion by returning TIPC_OK instead of 0. (The TIPC_OK symbol has the value 0, but it should only be used in contexts that deal with the error code field of a TIPC message header.)

* tipc: Fix race condition that could cause accept() to failAllan Stephens2008-07-15
| | | | | | | | | | | | | | This patch ensurs that accept() returns successfully even when the newly created socket is immediately disconnected by its peer. Previously, accept() would fail if it was unable to pass back the optional address info for the socket's peer before the socket became disconnected; TIPC now allows accept() to gather peer address information after disconnection. As a bonus, the revised code accesses the socket's port more efficiently, without the overhead incurred by a reference table lookup.

* tipc: Remove unneeded parameter to tipc_createport_raw()Allan Stephens2008-07-15
| | | | | | | | | | This patch eliminates an unneeded parameter when creating a low-level TIPC port object. Instead of returning both the pointer to the port structure and the port's reference ID, it now returns only the pointer since the port structure contains the reference ID as one of its fields.

* netlabel: return msg overflow error from netlbl_cipsov4_list fasterDenis V. Lunev2008-07-15
| | | | | | | | | | | | | | Currently, we are trying to place the information from the kernel to 1, 2, 3 and 4 pages sequentially. These pages are allocated via slab. Though, from the slab point of view steps 3 and 4 are equivalent on most architectures. So, lets skip 3 pages attempt. By the way, should we switch from .doit to .dumpit interface here?

* ipv4: Fix ipmr unregister device oopsWang Chen2008-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | An oops happens during device unregister. The following oops happened when I add two tunnels, which use a same device, and then delete one tunnel. Obviously deleting tunnel "A" causes device unregister, which send a notification, and after receiving notification, ipmr do unregister again for tunnel "B" which also use same device. That is wrong. After receiving notification, ipmr only needs to decrease reference count and don't do duplicated unregister. Fortunately, IPv6 side doesn't add tunnel in ip6mr, so it's clean. This patch fixs: - unregister device oops - using after dev_put() Here is the oops: === Jul 11 15:39:29 wangchen kernel: ------------[ cut here ]------------ Jul 11 15:39:29 wangchen kernel: kernel BUG at net/core/dev.c:3651!

| * mac80211: fix TX sequence numbersJohannes Berg2008-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes mac80211 assign proper sequence numbers to QoS-data frames. It also removes the old sequence number code because we noticed that only the driver or hardware can assign sequence numbers to non-QoS-data and especially management frames in a race-free manner because beacons aren't passed through mac80211's TX path. This patch also adds temporary code to the rt2x00 drivers to not break them completely, that code will have to be reworked for proper sequence numbers on beacons. It also moves sequence number assignment down in the TX path so no sequence numbers are assigned to frames that are dropped.

| * wext: make sysfs bits optional and deprecate themJohannes Berg2008-07-14
| | | | | | | | | | | | | | | | | | | | | | The /sys/class/net/*/wireless/ direcory is, as far as I know, not used by anyone. Additionally, the same data is available via wext ioctls. Hence the sysfs files are pretty much useless. This patch makes them optional and schedules them for removal.

| * mac80211: Fix ieee80211_rx_reorder_ampdu: ignore QoS null packetsEmmanuel Grumbach2008-07-14
| | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the check at the entrance to ieee80211_rx_reorder_ampdu. This check has been broken by 'mac80211: rx.c use new helpers'. Letting QoS NULL packet in ieee80211_rx_reorder_ampdu led to packet loss in RX.

| * mac80211: revamp beacon configurationJohannes Berg2008-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch changes mac80211's beacon configuration handling to never pass skbs to the driver directly but rather always require the driver to use ieee80211_beacon_get(). Additionally, it introduces "change flags" on the config_interface() call to enable drivers to figure out what is changing. Finally, it removes the beacon_update() driver callback in favour of having IBSS beacon delivered by ieee80211_beacon_get() as well.

| | | | | | | | | | | | | | | | | | This patch pushes the "netif_running()" and "same type as before" checks down into ieee80211_if_change_type() to centralise the logic instead of duplicating it for cfg80211 and wext.

| * mac80211: make master netdev handling saneJohannes Berg2008-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, almost every interface type has a 'bss' pointer pointing to BSS information. This BSS information, however, is for a _local_ BSS, not for the BSS we joined, so having it on a STA mode interface makes little sense, but now they have it pointing to the master device, which is an AP mode virtual interface. However, except for some bitrate control data, this pointer is only used in AP/VLAN modes (for power saving stations.) Overall, it is not necessary to even have the master netdev be a valid virtual interface, and it doesn't have to be on the list of interfaces either. This patch changes the master netdev to be special, it now - no longer is on the list of virtual interfaces, which lets me remove a lot of tests for that - no longer has sub_if_data attached, since that isn't used Additionally, this patch changes some vlan/ap mode handling that is related to these 'bss' pointers described above (but in the VLAN case they actually make sense because there they point to the AP they belong to); it also adds some debugging code to IEEE80211_DEV_TO_SUB_IF to validate it is not called on the master netdev any more.

| * | dccp ccid-3: Length of loss intervalsGerrit Renker2008-07-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This corrects an error in the computation of the open loss interval I_0: * the interval length is (highest_seqno - start_seqno) + 1 * and not (highest_seqno - start_seqno). This condition was not fully clear in RFC 3448, but reflects the current revision state of rfc3448bis and is also consistent with RFC 4340, 6.1.1. Further changes: ---------------- * variable renamed due to line length constraints; * explicit typecast to `s64' to avoid implicit signed/unsigned casting.
