Drivers should be able to call cfg80211_sched_scan_results() from atomic context. However, with the introduction of multiple scheduled scan feature this requirement was not taken into account resulting in regression shown below.

Mesh forwarding path checks for address extension mode to fetch appropriate proxied address and MPP address. Existing condition that looks for 6 address format is not strict enough so that frames with improper values are processed and invalid entries are added into MPP table. Fix that by adding a stricter check before processing the packet. Per IEEE Std 802.11s-2011 spec. Table 7-6g1 lists address extension mode 0x3 as reserved one. And also Table Table 9-13 does not specify 0x3 as valid address field. Fixes: 9b395bc3 ("mac80211: verify that skb data is present") Signed-off-by:

The zero padding that is added to NTB's does not zero the memory correctly. This is because the skb_put modifies the value of skb_out->len which results in the memset command not setting any memory to zero as (ctx->tx_max - skb_out->len) == 0. I have resolved this by storing the size of the memory to be zeroed before the skb_put and using this in the memset call. Signed-off-by:

The patch fixes two things at once: 1) It checks the env->allow_ptr_leaks and only prints the map address to the log if we have the privileges to do so, otherwise it just dumps 0 as we would when kptr_restrict is enabled on %pK. Given the latter is off by default and not every distro sets it, I don't want to rely on this, hence the 0 by default for unprivileged. 2) Printing of ldimm64 in the verifier log is currently broken in that we don't print the full immediate, but only the 32 bit part of the first insn part for ldimm64. Thus, fix this up as well; it's okay to access, since we verified all ldimm64 earlier already (including just constants) through replace_map_fd_with_map_ptr().

Vlan devices, like all other software devices, enable NETIF_F_HW_CSUM feature. However, unlike all the othe other software devices, vlans will switch to using IP|IPV6_CSUM features, if the underlying devices uses them. In these situations, checksum offload features on the vlan device can't be controlled via ethtool. This patch makes vlans keep HW_CSUM feature if the underlying device supports checksum offloading. This makes vlan devices behave like other software devices, and restores control to the user. A side-effect is that some offload settings (typically UFO) may be enabled on the vlan device while being disabled on the HW. However, the GSO code will correctly process the packets. This actually results in slightly better raw throughput. Signed-off-by:

IPv4 dst could use fi->fib_metrics to store metrics but fib_info itself is refcnt'ed, so without taking a refcnt fi and fi->fib_metrics could be freed while dst metrics still points to it. This triggers use-after-free as reported by Andrey twice. This patch reverts commit 2860583f ("ipv4: Kill rt->fi") to restore this reference counting. It is a quick fix for -net and -stable, for -net-next, as Eric suggested, we can consider doing reference counting for metrics itself instead of relying on fib_info. IPv6 is very different, it copies or steals the metrics from mx6_config in fib6_commit_metrics() so probably doesn't need a refcnt. Decnet has already done the refcnt'ing, see dn_fib_semantic_match(). Fixes: 2860583f ("ipv4: Kill rt->fi") Reported-by:

Since groups 0 and 63 are invalid, we should check for those bits. Note that the 802.11 spec specifies the *bit* order, but the CPU doesn't care about bit order since it can't address bits, so it's always treating BIT(0) as the lowest bit within a byte. Reported-by:

Whole point of randomization was to hide server uptime, but an attacker can simply start a syn flood and TCP generates 'old style' timestamps, directly revealing server jiffies value. Also, TSval sent by the server to a particular remote address vary depending on syncookies being sent or not, potentially triggering PAWS drops for innocent clients. Lets implement proper randomization, including for SYNcookies. Also we do not need to export sysctl_tcp_timestamps, since it is not used from a module. In v2, I added Florian feedback and contribution, adding tsoff to tcp_get_cookie_sock(). v3 removed one unused variable in tcp_v4_connect() as Florian spotted.

Pull USB updates from Greg KH: "Here is the big USB patchset for 4.12-rc1. Lots of good stuff here, after many many many attempts, the kernel finally has a working typeC interface, many thanks to Heikki and Guenter and others who have taken the time to get this merged. It wasn't an easy path for them at all. There's also a staging driver that uses this new api, which is why it's coming in through this tree. Along with that, there's the usual huge number of changes for gadget drivers, xhci, and other stuff. Johan also finally refactored pretty much every driver that was looking at USB endpoints to do it in a common way, which will help prevent any "badly-formed" devices from causing problems in drivers. That too wasn't a simple task.

Pull networking fixes from David Miller: 1) The wireless rate info fix from Johannes Berg. 2) When a RAW socket is in hdrincl mode, we need to make sure that the user provided at least a minimally sized ipv4/ipv6 header. Fix from Alexander Potapenko. 3) We must emit IFLA_PHYS_PORT_NAME netlink attributes using nla_put_string() so that it is NULL terminated. 4) Fix a bug in TCP fastopen handling, wherein child sockets erroneously inherit the fastopen_req from the parent, and later can end up derefencing freed memory or doing a double free. From Eric Dumazet. 5) Don't clear out netdev stats at close time in tg3 driver, from YueHaibing. 6) Fix refcount leak in xt_CT, from Gao Feng. 7) In nft_set_bitmap() don't leak dummy elements, from Liping Zhang. 8) Fix deadlock due to taking the expectation lock twice, also from Liping Zhang. 9) Make xt_socket work again with ipv6, from Peter Tirsek. 10) Don't allow IPV6 to be used with IPVS if ipv6.disable=1, from Paolo Abeni. 11) Make the BPF loader more flexible wrt. changes to the bpf MAP entry layout. From Jesper Dangaard Brouer. 12) Fix ethtool reported device name in aquantia driver, from Pavel Belous. 13) Fix build failures due to the compile time size test not working in netfilter conntrack.

Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.12 kernel cycle. Core changes: - Return NULL from gpiod_get_optional() when GPIOLIB is disabled. This was a much discussed change. It affects use cases where people write drivers that might or might not be using GPIO resources. I have decided that this is the lesser evil right now. - Make gpiod_count() behave consistently across different hardware descriptions. - Fix the syntax around open drain/open source to not infer active high/low semantics. New drivers: - A new single-register fixed-direction framework driver for hardware that have lines controlled by a single register that just work in one direction (out or in), including IRQ support. - Support the Fintek F71889A GPIO SuperIO controller. - Support the National NI 169445 MMIO GPIO. - Support for the X-Gene derivative of the DWC GPIO controller - Support for the Rohm BD9571MWV-M PMIC GPIO controller. - Refactor the Gemini GPIO driver to a generic Faraday FTGPIO driver and replace both the Gemini and the Moxa ART custom drivers with this driver. Driver improvements: - A whole slew of drivers have their spinlocks chaned to raw spinlocks as they provide irqchips, and thus we are progressing on realtime compliance. - Use devm_irq_alloc_descs() in a slew of drivers, getting managed resources. - Support for the embedded PWM controller inside the MVEBU driver. - Debounce, open source and open drain support for the Aspeed driver. - Misc smaller fixes like spelling and syntax and whatnot" * tag 'gpio-v4.12-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (77 commits) gpio: f7188x: Add a missing break gpio: omap: return error if requested debounce time is not possible gpio: Add ROHM BD9571MWV-M PMIC GPIO driver gpio: gpio-wcove: fix GPIO IRQ status mask gpio: DT bindings, move tca9554 from pcf857x to pca953x gpio: move tca9554 from pcf857x to pca953x gpio: arizona: Correct check whether the pin is an input gpio: Add XRA1403 DTS binding documentation dt-bindings: add exar to vendor prefixes list gpio: gpio-wcove: fix irq pending status bit width gpio: dwapb: use dwapb_read instead of readl_relaxed gpio: aspeed: Add open-source and open-drain support gpio: aspeed: Add debounce support gpio: aspeed: dt: Add optional clocks property gpio: aspeed: dt: Fix description alignment in bindings document gpio: mvebu: Add limited PWM support gpio: Use unsigned int for interrupt numbers gpio: f7188x: Add F71889A GPIO support. gpio: core: Decouple open drain/source flag with active low/high gpio: arizona: Correct handling for reading input GPIOs ... -
