Pablo Neira Ayuso says: ==================== Netfilter/IPVS updates for net-next This small patchset contains three accumulated Netfilter/IPVS updates, they are: 1) Refactorize common NAT code by encapsulating it into a helper function, similarly to what we do in other conntrack extensions, from Florian Westphal. 2) A minor format string mismatch fix for IPVS, from Masanari Iida. 3) Add quota support to the netfilter accounting infrastructure, now you can add quotas to accounting objects via the nfnetlink interface and use them from iptables. You can also listen to quota notifications from userspace. This enhancement from Mathieu Poirier. ==================== Signed-off-by: David S. Miller <[email protected]>

2014-05-30af_iucv: correct cleanup if listen backlog is fullUrsula Braun1-2/+1
In case of transport HIPER a sock struct is allocated for an incoming connect request. If the backlog queue is full this socket is not needed, but is left in the list of af_iucv sockets. Final socket release posts console message "Attempt to release alive iucv socket". This patch makes sure the new created socket is cleaned up correctly if the backlog queue is full.

For the mac80211 bits, Johannes says: "Here I just have Heikki's rfkill GPIO cleanups. The ARM/tegra patch is OK with the maintainer (Stephen). Let me know of any problems." and; "We have a whole bunch of work on CSA by Andrei, Luca and Michal, but unfortunately it doesn't seem quite complete yet so it's still disabled. There's some TDLS work from Arik, and the rest is mostly minor fixes and cleanups." For the NFC bits, Samuel says: "This is the NFC pull request for 3.16. We have: - STMicroeectronics st21nfca support. The st21nfca is an HCI chipset and thus relies on the HCI stack. This submission provides support for tag redaer/writer mode (including Type 5) and device tree bindings. - PM runtime support and a bunch of bug fixes for TI's trf7970a. - Device tree support for NXP's pn544. Legacy platform data support is obviously kept intact. - NFC Tag type 4B support to the NFC Digital stack. - SOCK_RAW type support to the raw NFC socket, and allow NCI sniffing from that. This can be extended to report HCI frames and also proprietarry ones like e.g. the pn533 ones." For the iwlwifi bits, Emmanuel says: "Eran continues to work on new devices, Eyal is still digging in the rate control stuff, and Johannes added new functionality to the debug system we have in place now along with a few cleanups he made on the way. That's pretty much it." and; "Avri continues to work on the power code and Eran is improving the NVM handling as a preparations for new devices on which he works with Liad. Luca cleans up a bit the code while working on CSA. I have the regular BT Coex stuff and a small lockdep fix. Johannes has his regular amount of clean ups and improvements, the main one is the ability to leave 2 chains open to improve diversity and hence the throughput in high attenuation scenarios." and; "The regular amount of housekeeping here. I merged iwlwifi-fixes.git to be able to add the patch you didn't want in wireless.git at that stage of the -rc cycle. Luca has a few preparations for CSA implementation and also what seems to be a bugfix for P2P but hasn't caused issues we could notice." For the Atheros bits, Kalle says: "For ath10k Michal did various small fixes on how we handle hardware/firmware problems and he also fixed two memory leaks."

2014-05-26mac80211: add a single-transaction driver op to switch contextsLuciano Coelho2-0/+138
In some cases, when the driver is already using all the channel contexts it can handle at once, we have to do an in-place switch (ie. we cannot afford using an extra context temporarily for the transaction). But some drivers may not support switching the channel context assigned to a vif on the fly (ie. without unassigning and assigning it) while others may only work if the context is changed on the fly, without unassigning it first. To allow these different scenarios, add a new driver operation that let's the driver decide how to handle an in-place switch.

2014-05-26netfilter: bridge: fix Kconfig unmet dependenciesPablo Neira2-6/+3
Before f5efc69 ("netfilter: nf_tables: Add meta expression key for bridge interface name"), the entire net/bridge/netfilter/ directory depended on BRIDGE_NF_EBTABLES, ie. on ebtables. However, that directory already contained the nf_tables bridge extension that we should allow to compile separately. In f5efc69, we tried to generalize this by using CONFIG_BRIDGE_NETFILTER which was not a good idea since this option already existed and it is dedicated to enable the Netfilter bridge IP/ARP filtering. Let's try to fix this mess by: 1) making net/bridge/netfilter/ dependent on the toplevel CONFIG_NETFILTER option, just like we do with the net/netfilter and net/ipv{4,6}/netfilter/ directories. 2) Changing 'selects' to 'depends on' NETFILTER_XTABLES for BRIDGE_NF_EBTABLES. I believe this problem was already before f5efc69: warning: (BRIDGE_NF_EBTABLES) selects NETFILTER_XTABLES which has unmet direct dependencies (NET && INET && NETFILTER) 3) Fix ebtables/nf_tables bridge dependencies by making NF_TABLES_BRIDGE and BRIDGE_NF_EBTABLES dependent on BRIDGE and NETFILTER: warning: (NF_TABLES_BRIDGE && BRIDGE_NF_EBTABLES) selects BRIDGE_NETFILTER which has unmet direct dependencies (NET && BRIDGE && NETFILTER && INET && NETFILTER_ADVANCED) net/built-in.o: In function `br_parse_ip_options': br_netfilter.c:(.text+0x4a5ba): undefined reference to `ip_options_compile' br_netfilter.c:(.text+0x4a5ed): undefined reference to `ip_options_rcv_srr' net/built-in.o: In function `br_nf_pre_routing_finish': br_netfilter.c:(.text+0x4a8a4): undefined reference to `ip_route_input_noref' br_netfilter.c:(.text+0x4a987): undefined reference to `ip_route_output_flow' make: *** [vmlinux] Error 1 Reported-by: Jim Davis <[email protected]> Signed-off-by: Pablo Neira Ayuso <[email protected]> Signed-off-by: David S.

Similarly a bug fix to send ALB packets in the bonding driver using the right source address overlaps with cleanups in net-next. Signed-off-by: David S. Miller <[email protected]>

Pull networking fixes from David Miller: "It looks like a sizeble collection but this is nearly 3 weeks of bug fixing while you were away. 1) Fix crashes over IPSEC tunnels with NAT, the latter can reroute the packet through a non-IPSEC protected path and the code has to be able to handle SKBs attached to routes lacking an attached xfrm state. From Steffen Klassert. 2) Fix OOPSs in ipv4 and ipv6 ipsec layers for unsupported sub-protocols, also from Steffen Klassert. 3) Set local_df on fragmented netfilter skbs otherwise we won't be able to forward successfully, from Florian Westphal. 4) cdc_mbim ipv6 neighbour code does __vlan_find_dev_deep without holding RCU lock, from Bjorn Mork. 5) local_df test in ip_may_fragment is inverted, from Florian Westphal. 6) jme driver doesn't check for DMA mapping failures, from Neil Horman. 7) qlogic driver doesn't calculate number of TX queues properly, from Shahed Shaikh. 8) fib_info_cnt can drift irreversibly positive if we fail to allocate the fi->fib_metrics array, from Sergey Popovich. 9) Fix use after free in ip6_route_me_harder(), also from Sergey Popovich. 10) When SYSCTL is disabled, we don't handle local_port_range and ping_group_range defaults properly at all, from Cong Wang. 11) Unaccelerated VLAN tagged frames improperly handled by cdc_mbim driver, fix from Bjorn Mork. 12) cassini driver needs nested lock annotations for TX locking, from Emil Goode. 13) On init error ipv6 VTI driver can unregister pernet ops twice, oops. Fix from Mahtias Krause. 14) If macvlan device is down, don't propagate IFF_ALLMULTI changes, from Peter Christensen. 15) Missing NULL pointer check while parsing netlink config options in ip6_tnl_validate(). From Susant Sahani. 16) Fix handling of neighbour entries during ipv6 router reachability probing, from Duan Jiong. 17) x86 and s390 JIT address randomization has some address calculation bugs leading to crashes, from Alexei Starovoitov and Heiko Carstens. 18) Clear up those uglies with nop patching and net_get_random_once(), from Hannes Frederic Sowa. 19) Option length miscalculated in ip6_append_data(), fix also from Hannes Frederic Sowa. 20) A while ago we fixed a race during device unregistry when a namespace went down, turns out there is a second place that needs similar protection. From Cong Wang. 21) In the new Altera TSE driver multicast filtering isn't working, disable it and just use promisc mode until the cause is found. From Vince Bridgers. 22) When we disable router enabling in ipv6 we have to flush the cached routes explicitly, from Duan Jiong. 23) NBMA tunnels should not cache routes on the tunnel object because the key is variable, from Timo Teräs. 24) With stacked devices GRO information in skb->cb[] can be not setup properly, make sure it is in all code paths. From Eric Dumazet. 25) Really fix stacked vlan locking, multiple levels of nesting with intervening non-vlan devices are possible. From Vlad Yasevich. 26) Fallback ipip tunnel device's mtu is not setup properly, from Steffen Klassert. 27) The packet scheduler's tcindex filter can crash because we structure copy objects with list_head's inside, oops. From Cong Wang. 28) Fix CHECKSUM_COMPLETE handling for ipv6 GRE tunnels, from Eric Dumazet. 29) In some configurations 'itag' in __mkroute_input() can end up being used uninitialized because of how fib_validate_source() works.

2014-05-23net: filter: let unattached filters use sock_fprog_kernDaniel Borkmann4-6/+7
The sk_unattached_filter_create() API is used by BPF filters that are not directly attached or related to sockets, and are used in team, ptp, xt_bpf, cls_bpf, etc. As such all users do their own internal managment of obtaining filter blocks and thus already have them in kernel memory and set up before calling into sk_unattached_filter_create(). As a result, due to __user annotation in sock_fprog, sparse triggers false positives (incorrect type in assignment [different address space]) when filters are set up before passing them to sk_unattached_filter_create(). Therefore, let sk_unattached_filter_create() API use sock_fprog_kern to overcome this issue.

2014-05-23net: filter: remove DL macroDaniel Borkmann1-94/+99
Lets get rid of this macro. After commit 5bcfedf06f7f ("net: filter: simplify label names from jump-table"), labels have become more readable due to omission of BPF_ prefix but at the same time more generic, so that things like `git grep -n` would not find them. As a middle path, lets get rid of the DL macro as it's not strictly needed and would otherwise just hide the full name.

2014-05-23net: Make enabling of zero UDP6 csums more restrictiveTom Herbert2-5/+23
RFC 6935 permits zero checksums to be used in IPv6 however this is recommended only for certain tunnel protocols, it does not make checksums completely optional like they are in IPv4. This patch restricts the use of IPv6 zero checksums that was previously intoduced. no_check6_tx and no_check6_rx have been added to control the use of checksums in UDP6 RX and TX path. The normal sk_no_check_{rx,tx} settings are not used (this avoids ambiguity when dealing with a dual stack socket). A helper function has been added (udp_set_no_check6) which can be called by tunnel impelmentations to all zero checksums (send on the socket, and accept them as valid).

2014-05-23net-next:v4: Add support to configure SR-IOV VF minimum and maximum Tx rate ↵Sucheta Chakraborty1-6/+32
through ip tool. o min_tx_rate puts lower limit on the VF bandwidth. VF is guaranteed to have a bandwidth of at least this value. max_tx_rate puts cap on the VF bandwidth. VF can have a bandwidth of up to this value. o A new handler set_vf_rate for attr IFLA_VF_RATE has been introduced which takes 4 arguments: netdev, VF number, min_tx_rate, max_tx_rate o ndo_set_vf_rate replaces ndo_set_vf_tx_rate handler. o Drivers that currently implement ndo_set_vf_tx_rate should now call ndo_set_vf_rate instead and reject attempt to set a minimum bandwidth greater than 0 for IFLA_VF_TX_RATE when IFLA_VF_RATE is not yet implemented by driver. o If user enters only one of either min_tx_rate or max_tx_rate, then, userland should read back the other value from driver and set both for IFLA_VF_RATE. Drivers that have not yet implemented IFLA_VF_RATE should always return min_tx_rate as 0 when read from ip tool. o If both IFLA_VF_TX_RATE and IFLA_VF_RATE options are specified, then IFLA_VF_RATE should override. o Idea is to have consistent display of rate values to user. o Usage example: - ./ip link set p4p1 vf 0 rate 900 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f0 brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5a, tx rate 900 (Mbps), max_tx_rate 900Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a ./ip link set p4p1 vf 0 max_tx_rate 300 min_tx_rate 200 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f0 brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5a, tx rate 300 (Mbps), max_tx_rate 300Mbps, min_tx_rate 200Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a ./ip link set p4p1 vf 0 max_tx_rate 600 rate 300 ./ip link show p4p1 32: p4p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT qlen 1000 link/ether 00:0e:1e:08:b0:f brd ff:ff:ff:ff:ff:ff vf 0 MAC 3e:a0:ca:bd:ae:5, tx rate 600 (Mbps), max_tx_rate 600Mbps, min_tx_rate 200Mbps vf 1 MAC f6:c6:7c:3f:3d:6c vf 2 MAC 56:32:43:98:d7:71 vf 3 MAC d6:be:c3:b5:85:ff vf 4 MAC ee:a9:9a:1e:19:14 vf 5 MAC 4a:d0:4c:07:52:18 vf 6 MAC 3a:76:44:93:62:f9 vf 7 MAC 82:e9:e7:e3:15:1a Signed-off-by: Sucheta Chakraborty <[email protected]> Signed-off-by: David S.

2014-05-23Bluetooth: Clearly distinguish mgmt LTK type from authenticated propertyJohan Hedberg1-3/+16
On the mgmt level we have a key type parameter which currently accepts two possible values: 0x00 for unauthenticated and 0x01 for authenticated. However, in the internal struct smp_ltk representation we have an explicit "authenticated" boolean value. To make this distinction clear, add defines for the possible mgmt values and do conversion to and from the internal authenticated value.
