2010-04-15netfilter: bridge-netfilter: simplify IP DNATBart De Schuymer
Remove br_netfilter.c::br_nf_local_out(). The function br_nf_local_out() was needed because the PF_BRIDGE::LOCAL_OUT hook could be called when IP DNAT happens on to-be-bridged traffic. The new scheme eliminates this mess. Signed-off-by: Bart De Schuymer <bdschuym@pandora.be> Signed-off-by: Patrick McHardy <kaber@trash.net>

2010-04-15net: netif_rx() must disable preemptionEric Dumazet
Eric Paris reported netif_rx() is calling smp_processor_id() from preemptible context, in particular when caller is ip_dev_loopback_xmit(). RPS commit added this smp_processor_id() call, this patch makes sure preemption is disabled. rps_get_cpus() wants rcu_read_lock() anyway, we can dot it a bit earlier.

2010-04-14ixgbe: fix bug with vlan strip in promsic modeJesse Brandeburg
The ixgbe driver was setting up 82598 hardware correctly, so that when promiscuous mode was enabled hardware stripping was turned off. But on 82599 the logic to disable/enable hardware stripping is different, and the code was not updated correctly when the hardware vlan stripping was enabled as default. This change comprises the creation of two new helper functions and calling them from the right locations to disable and enable hardware stripping of vlan tags at appropriate times.

2010-04-14ath9k-htc: fix lockdep warning and kernel warning after unplugging ar9271 ↵Ming Lei
usb device This patch fixes two warnings below after unplugging ar9271 usb device: -one is a kernel warning[1] -another is a lockdep warning[2] The root reason is that __skb_queue_purge can't be executed in hardirq context, so the patch forks ath9k_skb_queue_purge(ath9k version of _skb_queue_purge), which frees skb with dev_kfree_skb_any which can be run in hardirq context safely, then prevent the lockdep warning and kernel warning after unplugging ar9271 usb device.

2010-04-14ath5k: treat RXORN as non-fatalBruno Randolf
We get RXORN interrupts when all receive buffers are full. This is not necessarily a fatal situation. It can also happen when the bus is busy or the CPU is not fast enough to process all frames. Older chipsets apparently need a reset to come out of this situration, but on newer chips we can treat RXORN like RX, as going thru a full reset does more harm than good, there. The exact chip revisions which need a reset are unknown - this guess AR5K_SREV_AR5212 ("venice") is copied from the HAL. Inspired by openwrt 413-rxorn.patch: "treat rxorn like rx, reset after rxorn seems to do more harm than good" Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W.

2010-04-14ath5k: Use high bitrates for ACK/CTSBruno Randolf
There was a confusion in the usage of the bits AR5K_STA_ID1_ACKCTS_6MB and AR5K_STA_ID1_BASE_RATE_11B. If they are set (1), we will get lower bitrates for ACK and CTS. Therefore ath5k_hw_set_ack_bitrate_high(ah, false) actually resulted in high bitrates, which i think is what we want anyways. Cleared the confusion and added some documentation.

2010-04-14tun: orphan an skb on txMichael S. Tsirkin
The following situation was observed in the field: tap1 sends packets, tap2 does not consume them, as a result tap1 can not be closed. This happens because tun/tap devices can hang on to skbs undefinitely. As noted by Herbert, possible solutions include a timeout followed by a copy/change of ownership of the skb, or always copying/changing ownership if we're going into a hostile device. This patch implements the second approach. Note: one issue still remaining is that since skbs keep reference to tun socket and tun socket has a reference to tun device, we won't flush backlog, instead simply waiting for all skbs to get transmitted. At least this is not user-triggerable, and this was not reported in practice, my assumption is other devices besides tap complete an skb within finite time after it has been queued. A possible solution for the second issue would not to have socket reference the device, instead, implement dev->destructor for tun, and wait for all skbs to complete there, but this needs some thought, probably too risky for 2.6.34.

2010-04-14stmmac: new descriptor field for the driver's platformGiuseppe CAVALLARO
The new enh_desc is used for selecting the enhanced descriptors structure. There are several scenarios; some chips (mac10/100 or gmac) want to use the enhanced descriptors; others want the normal ones. For example, on ST platforms: MAC10/100 uses the normal desc structure and the GMAC uses the enhanced one. It can be useful to get this information from the platform. This could also be decided at run-time looking at the chip's ID number; but it could happen that chips with the same ID want to use different descriptor structure.

2010-04-14stmmac: rework normal and enhanced descriptorsGiuseppe CAVALLARO
Currently the driver assumes that the mac10/100 can only use the normal descriptor structure and the gmac can only use the enhanced structures.

2010-04-13ipv4: ipmr: support multiple tablesPatrick McHardy
This patch adds support for multiple independant multicast routing instances, named "tables". Userspace multicast routing daemons can bind to a specific table instance by issuing a setsockopt call using a new option MRT_TABLE. The table number is stored in the raw socket data and affects all following ipmr setsockopt(), getsockopt() and ioctl() calls. By default, a single table (RT_TABLE_DEFAULT) is created with a default routing rule pointing to it. Newly created pimreg devices have the table number appended ("pimregX"), with the exception of devices created in the default table, which are named just "pimreg" for compatibility reasons. Packets are directed to a specific table instance using routing rules, similar to how regular routing rules work. Currently iif, oif and mark are supported as keys, source and destination addresses could be supported additionally. Example usage: - bind pimd/xorp/... to a specific table: uint32_t table = 123; setsockopt(fd, IPPROTO_IP, MRT_TABLE, &table, sizeof(table)); - create routing rules directing packets to the new table: # ip mrule add iif eth0 lookup 123 # ip mrule add oif eth0 lookup 123 Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2010-04-13ipv4: ipmr: move unres_queue and timer to per-namespace dataPatrick McHardy
The unres_queue is currently shared between all namespaces. Following patches will additionally allow to create multiple multicast routing tables in each namespace. Having a single shared queue for all these users seems to excessive, move the queue and the cleanup timer to the per-namespace data to unshare it. As a side-effect, this fixes a bug in the seq file iteration functions: the first entry returned is always from the current namespace, entries returned after that may belong to any namespace.

2010-04-13net: fib_rules: decouple address families from real address familiesPatrick McHardy
Decouple the address family values used for fib_rules from the real address families in socket.h. This allows to use fib_rules for code that is not a real address family without increasing AF_MAX/NPROTO. Values up to 127 are reserved for real address families and map directly to the corresponding AF value, values starting from 128 are for other uses. rtnetlink is changed to invoke the AF_UNSPEC dumpit/doit handlers for these families.

Patrick McHardy notes: "We used to invoke IPv4 POST_ROUTING after fragmentation as well just to defragment the packets in conntrack immediately afterwards, but that got changed during the netfilter-ipsec integration. Ideally IPv6 would behave like IPv4." This patch makes it so. Sending an oversized frame (e.g. `ping6 -s64000 -c1 ::1`) will now show up in POSTROUTING as a single skb rather than multiple ones.

2010-04-13bcm63xx_enet: do not overwrite ENET_CTL_REG valueFlorian Fainelli
bcm_enet_hw_preinit will correctly set values in ENET_CTL_REG for internal or external MII operations, however, bcm_enet_open will blindly overwrite the ENET_CTL_REG register value and thus we will loose any changes to it that were made in bcm_enet_hw_preinit, rendering external MII operations non-working. This would lead to the driver not being able to check for link availability on external PHY setups, and thus we would never get to sending packets because link was down from the driver side. This was completely un-noticed because all boards out there but BCM6338-based ones use internal phy on their enet0 interface.
