inet_forward_change() runs with RTNL held. We are allowed to sleep if required. If we use __in_dev_get_rtnl() instead of __in_dev_get_rcu(), we no longer have to use GFP_ATOMIC allocations in inet_netconf_notify_devconf(), meaning we are less likely to miss notifications under memory pressure, and wont touch precious memory reserves either and risk dropping incoming packets. inet_netconf_get_devconf() can also use GFP_KERNEL allocation.

Jon Mason says: ==================== net: ethernet: bgmac: Add platform device support David Miller, Please consider including patches 1-5 in net-next Florian Fainelli, Please consider including patches 6 & 7 in devicetree/next Changes in v2: * Made device tree binding changes suggested by Sergei Shtylyov, Ray Jui, Rob Herring, Florian Fainelli, and Arnd Bergmann * Removed devm_* error paths in the bgmac_platform.c suggested by Florian Fainelli * Added Arnd Bergmann's Acked-by to the first 5 (there were changes outlined in the bullets above, but I believe them to be minor enough for him to not revoke his acks) This patch series adds support for other, non-bcma iProc SoC's to the bgmac driver. This series only adds NSP support, but we are interested in adding support for the Cygnus and NS2 families (with more possible down the road). To support non-bcma enabled SoCs, we need to add the standard device tree "platform device" support. Unfortunately, this driver is very tighly coupled with the bcma bus and much unwinding is needed. I tried to break this up into a number of patches to make it more obvious what was being done to add platform device support. I was able to verify that the bcma code still works using a 53012K board (NS SoC), and that the platform code works using a 58625K board (NSP SoC). ==================== Signed-off-by: -

The bcma portion of the driver has been split off into a bcma specific driver. This has been mirrored for the platform driver. The last references to the bcma core struct have been changed into a generic function call. These function calls are wrappers to either the original bcma code or new platform functions that access the same areas via MMIO. This necessitated adding function pointers for both platform and bcma to hide which backend is being used from the generic bgmac code. Signed-off-by:

The bgmac driver is using the bcma provides device ID and revision, as well as the SoC ID and package, to determine which features are necessary to enable, reset, etc in the driver. In anticipation of removing the bcma requirement for this driver, these must be changed to not reference that struct. In place of that, each "feature" has been given a flag, and the flags are enabled for their respective device and SoC. Signed-off-by:

Move the BCMA MDIO phy into a separate file, as it is very tightly coupled with the BCMA bus. This will help with the upcoming BCMA removal from the bgmac driver. Optimally, this should be moved into phy drivers, but it is too tightly coupled with the bgmac driver to effectively move it without more changes to the driver. Note: the phy_reset was intentionally removed, as the mdio phy subsystem automatically resets the phy if a reset function pointer is present. In addition to the moving of the driver, this reset function is added. Signed-off-by:

The bgmac_* print wrappers call dev_* prints with the dev pointer from the bcma core. In anticipation of removing the bcma requirement for this driver, these must be changed to not reference that struct. So, simply change all of the bgmac_* prints to their dev_* counterparts. In some cases netdev_* prints are more appropriate, so change those as well. Signed-off-by:

Simon Horman says: ==================== net: support MPLS in IPv4 and UDP This short series provides support for MPLS in IPv4 (RFC4023), and by virtue of FOU, MPLS in UDP (RFC7510). The changes are as follows: 1. Teach tunnel4.c about AF_MPLS, it already understands AF_INET and AF_INET6 2. Enhance IPIP and SIT to handle MPLS. Both already handle IPv4. SIT also already handles IPv6. 3. Trivially enhance MPLS to allow routes over SIT and IPIP tunnels. A corresponding patch set for iproute2 has also been provided. Changes since v1 * Correct inverted IPIP protocol logic in SIT patch * Provide usage example below Sample configuration follows: * The following creates a tunnel and routes MPLS packets whose outermost label is 100 over it. The forwarded packets will have the outermost label stack entry, 100, removed and two label stack entries added, the outermost having label 200 and the next having label 300. The local end-point for the tunnel is 10.0.99.192 and the remote endpoint is 10.0.99.193. The local address for encapsulated packets is 10.0.98.192 and the remote address is 10.0.98.193. # Create an MPLS over IPv4 tunnel using the IPIP driver ip link add name tun1 type ipip remote 10.0.99.193 local 10.0.99.192 \ ttl 225 mode mplsip # Bring the tunnel up and an add an IPv4 address and route ip link set up dev tun1 ip addr add 10.0.98.192/24 dev tun1 # Set MPLS route # Allow MPLS forwarding of packets recieved on eth0 echo 1 > /proc/sys/net/mpls/conf/eth0/input # Larger than label to be routed (100) echo 101 > /proc/sys/net/mpls/platform_labels ip -f mpls route add 100 as 200/300 via inet 10.0.98.193 * For FOU (in this case MPLS over UDP) a tunnel may created using: # Packets recieved on UDP port 6635 are MPLS over UDP (IP proto 137) ip fou add port 6635 ipproto 137 # Create the tunnel netdev ip link add name tun1 type ipip remote 10.0.99.193 local 10.0.99.192 \ ttl 225 mode mplsip encap fou encap-sport auto encap-dport 6635 IPv4 address, link and route, and MPLS routing commands are as per the MPLS over IPv4 example * To use the SIT driver instead of the IPIP driver "ipip" may be substituted for "sit" in the above examples. * To create a tunnel that forwards and receives all supported inner-protocols "mplsip" may be substituted for "any" in the above examples. For the IPIP driver this configures both IPv4 and MPLS over IPv4. For the SIT driver this configures IPv6, IPv4 and MPLS over IPv4. ==================== Signed-off-by: -

As was suggested this patch adds support for the different versions of MLD and IGMP query types. Since the user visible structure is still in net-next we can augment it instead of adding netlink attributes. The distinction between the different IGMP/MLD query types is done as suggested in Section 7.1, RFC 3376 [1] and Section 8.1, RFC 3810 [2] based on query payload size and code for IGMP. Since all IGMP packets go through multicast_rcv() and it uses ip_mc_check_igmp/ipv6_mc_check_mld we can be sure that at least the ip/ipv6 header can be directly used.

When we introduced GSO support, if using auth the auth chunk was being left queued on the packet even after the final segment was generated. Later on sctp_transmit_packet it calls sctp_packet_reset, which zeroed the packet len while not accounting for this left-over. This caused more space to be used the next packet due to the chunk still being queued, but space which wasn't allocated as its size wasn't accounted. The fix is to only queue it back when we know that we are going to generate another segment. Fixes: 90017acc ("sctp: Add GSO support") Signed-off-by:

over time there were multiple requests to access different data structures and fields of task_struct current, so finally add the helper to access 'current' as-is. Tracing bpf programs will do the rest of walking the pointers via bpf_probe_read(). Note that current can be null and bpf program has to deal it with, but even dumb passing null into bpf_probe_read() is still safe. Suggested-by:

The routing table of every switch in a tree is currently initialized to all zeros. This is an issue since 0 is a valid port number. Add a DSA_RTABLE_NONE=-1 constant to initialize the signed values of the routing table pointing to other switches. This fixes the device mapping of the mv88e6xxx driver where the port pointing to the switch itself and to non-existent switches was wrongly configured to be 0. It is now set to the expected 0xf value. Signed-off-by:

Merge tag 'rxrpc-rewrite-20160706' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs David Howells says: ==================== rxrpc: Improve conn/call lookup and fix call number generation [ver #3] I've fixed a couple of patch descriptions and excised the patch that duplicated the connections list for reconsideration at a later date. For reference, the excised patch is sitting on the rxrpc-experimental branch of my git tree, based on top of the rxrpc-rewrite branch. Diffing it against yesterday's tag shows no differences. Would you prefer the patch set to be emailed afresh instead of a git-pull request? David --- Here's the next part of the AF_RXRPC rewrite. The two main purposes of this set are to fix the call number handling and to make use of RCU when looking up the connection or call to pass a received packet to. Important changes in this set include: (1) Avoidance of placing stack data into SG lists in rxkad so that kernel stacks can become vmalloc'd (Herbert Xu). (2) Calls cease pinning the connection they used as soon as possible, which allows the connection to be discarded sooner and allows the call channel on that connection to be reused earlier. (3) Make each call channel on a connection have a separate and independent call number space rather than having a shared number space for the connection. Call numbers should increment monotonically per channel on the client, and the server should ignore a call with a lower call number for that channel than the latest it has seen. The RESPONSE packet sets the minimum values of each call ID counter on a connection. (4) Look up calls by indexing the channel array on a connection rather than by keeping calls in an rbtree on that connection. Also look up calls using the channel array rather than using a hashtable. The call hashtable can then be removed. (5) Call terminal statuses are cached in the channel array for the last call. It is assumed that if we the server have seen call N, then the client no longer cares about call N-1 on the same channel. This will allow retransmission of the terminal status in future without the need to keep the rxrpc_call struct around. (6) Peer lookups are moved out of common connection handling code and into service connection handling code as client connections (a) must point to a peer before they can be used and (b) are looked up by a machine-unique connection ID directly, so we only need to look up the peer first if we're going to deal with a service call. (7) The reference count on a connection is held elevated by 1 whilst it is alive (ie. idle unused connections have a refcount of 1). The reaper will attempt to change the refcount from 1->0 and skip if this cannot be done, whilst look ups only increment the refcount if it's non-zero. This makes the implementation of RCU lookups easier as we don't have to get a ref on the connection or a lock on the connection list to prevent a connection being reaped whilst we're contemplating queueing a packet that initiates a new service call upon it. If we need to get a connection, but there's a dead connection in the tree, we use rb_replace_node() to replace the dead one with a new one. (8) Use a seqlock to validate the walk over the service connection rbtree attached to a peer when it's being walked in RCU mode. (9) Make the incoming call/connection packet handling code use RCU mode and locks and make it only take a reference if the call/connection gets queued on a workqueue. The intention is that the next set will introduce the connection lifetime management and capacity limits to prevent clients from overloading the server. There are some fixes too: (1) Verifying that a packet coming in to a client connection came from the expected source. (2) Fix handling of connection failure in client call creation where we don't reinitialise the list linkage block and a second attempt to unlink the failed connection oopses and also we don't set the state correctly, which causes an assertion failure. (3) New service calls were being added to the socket's accept queue under the wrong lock. Changes: (V2) In rxrpc_find_service_conn_rcu() initialised the sequence number to 0. Fixed the RCU handling in conn_service.c by introducing and using rb_replace_node_rcu() as an RCU-safe alternative in rxrpc_publish_service_conn(). Modified and used rcu_dereference_raw() to avoid RCU sparse warnings in rxrpc_find_service_conn_rcu(). Added in some missing RCU dereference wrappers. It seems to be necessary to turn on CONFIG_PROVE_RCU_REPEATEDLY as well as CONFIG_SPARSE_RCU_POINTER to get the static __rcu annotation checking to happen. Fixed some other sparse warnings, including a missing ntohs() in jumbo packet processing. (V3) Fixed some commit descriptions. Excised the patch that duplicated the connection list to separate out the procfs list for reconsideration at a later date. ==================== Signed-off-by:

These new APIs also help in minimizing the number of memory barriers we end up issuing (in the ringbuffer code) since we can better control when we want to expose the ring state to the host.

hfsc_sched is huge (size: 920, cachelines: 15), but we can get it to 14 cachelines by placing level after filter_cnt (covering 4 byte hole) and reducing period/nactive/flags to u32 (period is just a counter, incremented when class becomes active -- 2**32 is plenty for this purpose, also, long is only 32bit wide on 32bit platforms anyway). cl_vtperiod is exported to userspace via tc_hfsc_stats, but its period member is already u32, so no precision is lost there either.

Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for net-next, they are: 1) Don't use userspace datatypes in bridge netfilter code, from Tobin Harding. 2) Iterate only once over the expectation table when removing the helper module, instead of once per-netns, from Florian Westphal. 3) Extra sanitization in xt_hook_ops_alloc() to return error in case we ever pass zero hooks, xt_hook_ops_alloc(): 4) Handle NFPROTO_INET from the logging core infrastructure, from Liping Zhang. 5) Autoload loggers when TRACE target is used from rules, this doesn't change the behaviour in case the user already selected nfnetlink_log as preferred way to print tracing logs, also from Liping Zhang. 6) Conntrack slabs with SLAB_HWCACHE_ALIGN to allow rearranging fields by cache lines, increases the size of entries in 11% per entry. From Florian Westphal. 7) Skip zone comparison if CONFIG_NF_CONNTRACK_ZONES=n, from Florian. 8) Remove useless defensive check in nf_logger_find_get() from Shivani Bhardwaj. 9) Remove zone extension as place it in the conntrack object, this is always include in the hashing and we expect more intensive use of zones since containers are in place. Also from Florian Westphal. 10) Owner match now works from any namespace, from Eric Bierdeman. 11) Make sure we only reply with TCP reset to TCP traffic from nf_reject_ipv4, patch from Liping Zhang. 12) Introduce --nflog-size to indicate amount of network packet bytes that are copied to userspace via log message, from Vishwanath Pai. This obsoletes --nflog-range that has never worked, it was designed to achieve this but it has never worked. 13) Introduce generic macros for nf_tables object generation masks. 14) Use generation mask in table, chain and set objects in nf_tables. This allows fixes interferences with ongoing preparation phase of the commit protocol and object listings going on at the same time. This update is introduced in three patches, one per object. 15) Check if the object is active in the next generation for element deactivation in the rbtree implementation, given that deactivation happens from the commit phase path we have to observe the future status of the object. 16) Support for deletion of just added elements in the hash set type. 17) Allow to resize hashtable from /proc entry, not only from the obscure /sys entry that maps to the module parameter, from Florian Westphal. 18) Get rid of NFT_BASECHAIN_DISABLED, this code is not exercised anymore since we tear down the ruleset whenever the netdevice goes away. 19) Support for matching inverted set lookups, from Arturo Borrero. 20) Simplify the iptables_mangle_hook() by removing a superfluous extra branch. 21) Introduce ether_addr_equal_masked() and use it from the netfilter codebase, from Joe Perches. 22) Remove references to "Use netfilter MARK value as routing key" from the Netfilter Kconfig description given that this toggle doesn't exists already for 10 years, from Moritz Sichert. 23) Introduce generic NF_INVF() and use it from the xtables codebase, from Joe Perches. 24) Setting logger to NONE via /proc was not working unless explicit nul-termination was included in the string. This fixes seems to leave the former behaviour there, so we don't break backward. ==================== Signed-off-by: -

Previously, mesh power management functionality works only with kernel MPM. Because user space MPM did not report mesh peer AID to kernel, the kernel could not identify the bit in TIM element. So this patch adds mesh peer AID setting API. Signed-off-by:

Continuing the workaround implemented in commit 23665aaf ("mac80211: Interoperability workaround for 80+80 and 160 MHz channels") use the same code to parse the Wide Bandwidth Channel Switch element by converting to VHT Operation element since the spec also just refers to that for parsing semantics, particularly with the workaround. While at it, remove some dead code - the IEEE80211_STA_DISABLE_40MHZ flag can never be set at this point since it's checked earlier and the wide_bw_chansw_ie pointer is set to NULL if it's set.

Add the following to support beacon report radio measurement with the measurement mode field set to passive or active: 1. Propagate the required scan duration to the device 2. Report the scan start time (in terms of TSF) 3. Report each BSS's detection time (also in terms of TSF) TSF times refer to the BSS that the interface that requested the scan is connected to.

Beacon report radio measurement requires reporting observed BSSs on the channels specified in the beacon request. If the measurement mode is set to passive or active, it requires actually performing a scan (passive or active, accordingly), and reporting the time that the scan was started and the time each beacon/probe was received (both in terms of TSF of the BSS of the requesting AP). If the request mode is table, this information is optional. In addition, the radio measurement request specifies the channel dwell time for the measurement. In order to use scan for beacon report when the mode is active or passive, add a parameter to scan request that specifies the channel dwell time, and add scan start time and beacon received time to scan results information. Supporting beacon report is required for Multi Band Operation (MBO). Signed-off-by:

Add radar_detect_widths to the interface combination that allows concurrent P2P Device dedicated interface and AP interfaces, to enable testing of radar detection when P2P Device interface is used. Clear the radar_detect_widths in case of multi channel contexts as this is not currently supported. As radar_detect_widths are now supported in all combinations, remove the hwsim_if_dfs_limits definition since it is no longer needed. Signed-off-by:
