2012-11-30wireless: allow Atheros card to not depend on ath.koVladimir Kondratiev
There are 2 different things: - sub-menu for "Atheros Wireless cards" family - module ath.ko with common Atheros code Until now, they both used to depend on the same Kconfig variable ATH_COMMON. Thus, being "Atheros card" and "depending on ath.ko" was the same. To allow module to belong to the "Atheros Wireless cards" family but not use ath.ko, 2 conditions above need to be separated. So, this patch introduce new Kconfig variable ATH_CARDS for belonging to the "Atheros Wireless Cards" family; while ATH_COMMON becomes hidden variable to express dependency on common Atheros code in ath.ko. Modules that depend on this common code now express it by setting ATH_COMMON. Right now, ath6kl do not depend on common code and thus do not set ATH_COMMON.

This patch removes an unused parameter (src_net) from rtnl_create_link() method and from the method single invocation, in veth. This parameter was used in the past when calling ops->get_tx_queues(src_net, tb) in rtnl_create_link(). The get_tx_queues() member of rtnl_link_ops was replaced by two methods, get_num_tx_queues() and get_num_rx_queues(), which do not get any parameter.

2012-11-30mISDN: improve bitops usageAkinobu Mita
This improves bitops usages in several points: - Convert u64 to a proper bitmap declaration. This enables to remove superfluous typecasting from 'u64' to 'unsigned long *'. - Convert superfluous atomic bitops to non atomic bitops. The bitmap is allocated on the stack and it is not accessed by any other threads, so using atomic bitops is not necessary. - Use find_next_zero_bit and find_next_zero_bit instead of calling test_bit() for each bit.

2012-11-308021q: fix vlan device to inherit the unicast filtering capability flagYi Zou
This bug is observed on running FCoE over a VLAN device associated w/ a real device that has IFF_UNICAST_FLT set since FCoE would add unicast address such as FLOGI MAC to the VLAN interface that FCoE is on. Since currently, VLAN device is not inheriting the IFF_UNICAST_FLT flag from the parent real device even though the real device is capable of doing unicast filtering. This forces the VLAN device and its real device go to promiscuous mode unnecessarily even the added address is actually being added to the available unicast filter table in real device.

2012-11-30bonding: delete migrated IP addresses from the rlb hash tableJiri Bohac
Bonding in balance-alb mode records information from ARP packets passing through the bond in a hash table (rx_hashtbl). At certain situations (e.g. link change of a slave), rlb_update_rx_clients() will send out ARP packets to update ARP caches of other hosts on the network to achieve RX load balancing. The problem is that once an IP address is recorded in the hash table, it stays there indefinitely. If this IP address is migrated to a different host in the network, bonding still sends out ARP packets that poison other systems' ARP caches with invalid information. This patch solves this by looking at all incoming ARP packets, and checking if the source IP address is one of the source addresses stored in the rx_hashtbl. If it is, but the MAC addresses differ, the corresponding hash table entries are removed. Thus, when an IP address is migrated, the first ARP broadcast by its new owner will purge the offending entries of rx_hashtbl. The hash table is hashed by ip_dst. To be able to do the above check efficiently (not walking the whole hash table), we need a reverse mapping (by ip_src). I added three new members in struct rlb_client_info: rx_hashtbl[x].src_first will point to the start of a list of entries for which hash(ip_src) == x. The list is linked with src_next and src_prev. When an incoming ARP packet arrives at rlb_arp_recv() rlb_purge_src_ip() can quickly walk only the entries on the corresponding lists, i.e. the entries that are likely to contain the offending IP address. To avoid confusion, I renamed these existing fields of struct rlb_client_info: next -> used_next prev -> used_prev rx_hashtbl_head -> rx_hashtbl_used_head (The current linked list is _not_ a list of hash table entries with colliding ip_dst. It's a list of entries that are being used; its purpose is to avoid walking the whole hash table when looking for used entries.)

2012-11-30bonding: rlb mode of bond should not alter ARP originating via bridgezheng.li
Do not modify or load balance ARP packets passing through balance-alb mode (wherein the ARP did not originate locally, and arrived via a bridge). Modifying pass-through ARP replies causes an incorrect MAC address to be placed into the ARP packet, rendering peers unable to communicate with the actual destination from which the ARP reply originated. Load balancing pass-through ARP requests causes an entry to be created for the peer in the rlb table, and bond_alb_monitor will occasionally issue ARP updates to all peers in the table instrucing them as to which MAC address they should communicate with; this occurs when some event sets rx_ntt. In the bridged case, however, the MAC address used for the update would be the MAC of the slave, not the actual source MAC of the originating destination. This would render peers unable to communicate with the destinations beyond the bridge.

2012-11-30pppoatm: drop frames to not-ready vccKrzysztof Mazur
The vcc_destroy_socket() closes vcc before the protocol is detached from vcc by calling vcc->push() with NULL skb. This leaves some time window, where the protocol may call vcc->send() on closed vcc and crash. Now pppoatm_send(), like vcc_sendmsg(), checks for vcc flags that indicate that vcc is not ready. If the vcc is not ready we just drop frame. Queueing frames is much more complicated because we don't have callbacks that inform us about vcc flags changes.

2012-11-30mac80211: fix for mesh sync to indicate TBTT adjustmentMarco Porsch
Currently the mesh sync code checks, whether peers indicate TBTT adjustment, but it never sets the corresponding flag itself. By setting ifmsh->tbtt_adjusting to true, it will set the corresponding field in the mesh configuration IE of own beacons. This indication will be set in the current beacon. The TBTT adjustment will be performed afterwards, affecting the next beacon. Thus, the first beacon with stable TBTT will not indicate adjustment anymore and peers will continue tracking the new offset.

2012-11-29core: make GRO methods static.Rami Rosen
This patch changes three methods to be static and removes their EXPORT_SYMBOLs in core/dev.c and their external declaration in netdevice.h. The methods, dev_gro_receive(), napi_frags_finish() and napi_skb_finish(), which are in the GRO rx path, are not used outside core/dev.c.

2012-11-29mac80211: re-organize the rx rate calculation logicSaravana
Currently the logic to fill a struct rate_info with a STA's last RX rate is accessible only in the cfg.c. As the RX rate calculation might be needed elsewhere, split this out into a separate function.
