This patch fixes ieee802154_get_fc_from_skb function on big endian machines. The function get_unaligned_le16 converts the byte order to host byte order but we want to keep the byte order like in mac header. Signed-off-by:

The RIOT-OS stack does send intra-pan frames but don't set the intra pan flag inside the mac header. It seems this is valid frame addressing but inefficient. Anyway this patch adds a new function for intra pan addressing, doesn't matter if intra pan flag or source and destination are the same. The newly introduction function will be used to check on intra pan addressing for 6lowpan. Signed-off-by:

The format of Intel Bluetooth firmware filename for bootloader product is ibt-<hw_variant>-<device_revision_id>.sfi Currently the driver uses a constant value 11 (0x0b) for hw_variant to support LnP/SfP product. But new product like WsP product has a different value such as 12 (0x0c). To support the multiple products, this patch replaces the constant value of hw_variant to the actual hw_variant value read from the device. Signed-off-by:

If recvmsg is called with a destination buffer that is too small to receive the contents of skb in its entirety, the return value from recvmsg was inconsistent with common SOCK_SEQPACKET or SOCK_DGRAM semantics. If destination buffer provided by userspace is too small (e.g. len < copied), then MSG_TRUNC flag is set and copied is returned. Instead, it should return the length of the message, which is consistent with how other datagram based sockets act. Quoting 'man recv': "All three calls return the length of the message on successful comple‐ tion. If a message is too long to fit in the supplied buffer, excess bytes may be discarded depending on the type of socket the message is received from." and "MSG_TRUNC (since Linux 2.2) For raw (AF_PACKET), Internet datagram (since Linux 2.4.27/2.6.8), netlink (since Linux 2.6.22), and UNIX datagram (since Linux 3.4) sockets: return the real length of the packet or datagram, even when it was longer than the passed buffer."

This patch reverts commit f9d1ce8f ("ieee802154: fix netns settings"). The lowpan interface need to be created inside the net namespace where the wpan interface is available. The wpan namespace can be changed only by nl802154 before. Without this patch it's not possible to create a lowpan interface for a wpan interface which isn't inside init_net namespace.

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: -

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.

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:

The current implementation of handling ADDBA Request while a session is already active with the peer is wrong - in case the peer is using the existing session's dialog token this should be treated as update to the session, which can update the timeout value.

It was first reported and reproduced by Petr (thanks!) in https://bugzilla.kernel.org/show_bug.cgi?id=119581 free_percpu(rt->rt6i_pcpu) used to always happen in ip6_dst_destroy(). However, after fixing a deadlock bug in commit 9c7370a1 ("ipv6: Fix a potential deadlock when creating pcpu rt"), free_percpu() is not called before setting non_pcpu_rt->rt6i_pcpu to NULL. It is worth to note that rt6i_pcpu is protected by table->tb6_lock. kmemleak somehow did not report it. We nailed it down by observing the pcpu entries in /proc/vmallocinfo (first suggested by Hannes, thanks!). Signed-off-by:

dn_fib_count_nhs() could enter an infinite loop if nhp->rtnh_len == 0 (i.e. if userspace passes a malformed netlink message). Let's use the helpers from net/nexthop.h which take care of all this stuff. We can do exactly the same as e.g. fib_count_nexthops() and fib_get_nhs() from net/ipv4/fib_semantics.c. This fixes the softlockup for me. Cc: Thomas Graf <tgraf@suug.ch> Signed-off-by:

We verify "u_cmd.outsize" and "u_cmd.insize" but we need to make sure that those values have not changed between the two copy_from_user() calls. Otherwise it could lead to a buffer overflow. Additionally, cros_ec_cmd_xfer() can set s_cmd->insize to a lower value. We should use the new smaller value so we don't copy too much data to the user. Reported-by:

Currently, link notifications are not sent by bond_set_slave_link_state() upon enslavement if the slave is enslaved when up. This happens because slave->link default init value is 0, which is the same as BOND_LINK_UP, resulting in bond_set_slave_link_state() ignoring this transition. This patch sets the default value of slave->link to BOND_LINK_NOCHANGE, assuring it will count as a state transition and thus trigger notification logic. Signed-off-by:

The Kconfig controlling build of this code is currently: drivers/connector/Kconfig:config PROC_EVENTS drivers/connector/Kconfig: bool "Report process events to userspace" ...meaning that it currently is not being built as a module by anyone. Lets remove the two modular references, so that when reading the driver there is no doubt it is builtin-only. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit.
