2017-04-20tcp: remove poll() flakes when receiving RSTEric Dumazet
When a RST packet is processed, we send two wakeup events to interested polling users. First one by a sk->sk_error_report(sk) from tcp_reset(), followed by a sk->sk_state_change(sk) from tcp_done(). Depending on machine load and luck, poll() can either return POLLERR, or POLLIN|POLLOUT|POLLERR|POLLHUP (this happens on 99 % of the cases) This is probably fine, but we can avoid the confusion by reordering things so that we have more TCP fields updated before the first wakeup. This might even allow us to remove some barriers we added in the past. Signed-off-by: Eric Dumazet <edumazet@google.com> Acked-by: Soheil Hassas Yeganeh <soheil@google.com> Signed-off-by: David S.

2017-04-20selftests/net: Fixes psock_fanout CBPF test caseMike Maloney
'psock_fanout' has been failing since commit 4d7b9dc1f36a9 ("tools: psock_lib: harden socket filter used by psock tests"). That commit changed the CBPF filter to examine the full ethernet frame, and was tested on 'psock_tpacket' which uses SOCK_RAW. But 'psock_fanout' was also using this same CBPF in two places, for filtering and fanout, on a SOCK_DGRAM socket. Change 'psock_fanout' to use SOCK_RAW so that the CBPF program used with SO_ATTACH_FILTER can examine the entire frame. Create a new CBPF program for use with PACKET_FANOUT_DATA which ignores the header, as it cannot see the ethernet header. Tested: Ran tools/testing/selftests/net/psock_{fanout,tpacket} 10 times, and they all passed.

2017-04-20mac80211: reject ToDS broadcast data framesJohannes Berg
AP/AP_VLAN modes don't accept any real 802.11 multicast data frames, but since they do need to accept broadcast management frames the same is currently permitted for data frames. This opens a security problem because such frames would be decrypted with the GTK, and could even contain unicast L3 frames. Since the spec says that ToDS frames must always have the BSSID as the RA (addr1), reject any other data frames. The problem was originally reported in "Predicting, Decrypting, and Abusing WPA2/802.11 Group Keys" at usenix https://www.usenix.org/conference/usenixsecurity16/technical-sessions/presentation/vanhoef and brought to my attention by Jouni.

Jiri Pirko says: ==================== mlxsw: Allow flow based forwarding in OVS This patchset does some fixes so the HW is setup correctly to do flow-based (ACL based) forwarding for OVS-enslaved port. The first patch is just trivial fix spotted on the way. Patches 2-4 take care of proper FID setup which HW needs in order to for ACL based forwarding. The 7th patch (with dependency of patch 5 and 6) takes care of proper setup of ports that are enslaved in OVS. The last patch implements new FID miss trap that is used to push packets belonging to unknown flows to kernel and userspace. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2017-04-20mlxsw: spectrum: Add FID miss trapJiri Pirko
When there is no FID set for a specific packet, the HW will drop it. However, by default these packets are useful to be delivered to CPU as it can inspect them and program HW accordingly. So add this trap. This would only ever happen when port is enslaved to an OVS master. Otherwise, packets would be dropped during VLAN / STP filtering, before FID classification.

In spectrum_switchdev code this is wrapped up by a helper function which actually does multiple calls to FW for bigger ranges. Move the code into mlxsw_sp_port_vlan_set and use it always.

The third port is an RMII/MII interface to a host master network interface (e.g. fixed link). While the LAN9303 device itself supports offload packet processing, this driver does not make use of it yet. This driver just configures the device to provide two separate network interfaces (which is the default state of a DSA device). Please note: the "MDIO managed mode" driver part isn't tested yet. I have used and tested the "I2C managed mode" only. Changes in v6: - fix support to use the driver as a module (core, i2c and mdio) - license info added in all parts of the driver (for module support) Changes in v5: - add missing include file to 'net/dsa/tag_lan9303.c' Changes in v4: - rebased on net-next, 'net/dsa/tag_lan9303.c' adapted to changed API Changes in v3: - 'ds_to_lan9303()' removed - special PHY reg MII_LAN911X_SPECIAL_CONTROL_STATUS mapping removed - compatible strings for I2C and MDIO are now different - MDIO-managed-mode devicetree binding added (still compile time tested only) Changes in v2: - code moved to 'drivers/net/dsa' - timeouts in completion wait loops - macros instead of various magic numbers - development code removed - devicetree property names changed - devicetree example adapted - tried to avoid to mix 'switching' and 'forwarding'...

2017-04-20HID: wacom: Override incorrect logical maximum contact identifierJason Gerecke
It apears that devices designed around Wacom's G11 chipset (e.g. Lenovo ThinkPad Yoga 260, Lenovo ThinkPad X1 Yoga, Dell XPS 12 9250, Dell Venue 8 Pro 5855, etc.) suffer from a common issue in their HID descriptors. The logical maximum is not updated for the "Contact Identifier" usage, leaving it as just "1" despite these devices being capable of tracking far more touches. Commit 60a221869803 began ignoring usages with out-of-range values, causing problems for devices based on this chipset. Touches after the first will have an out-of-range Contact Identifier, and ignoring that usage will cause the kernel to incorrectly slot each finger's events (along with all the knock-on userspace effects that entails). This commit checks for these buggy descriptors and updates the maximum where required. Prior chipsets have used "255" as the maximum (and the G11, at least, doesn't seem to actually use IDs outside the range of 1..CONTACTMAX) so continue using this value.
