2020-02-16net: phylink: clarify flow control settings in documentationRussell King
Clarify the expected flow control settings operation in the phylink documentation for each negotiation mode. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-02-16net: phylink: resolve fixed link flow controlRussell King
Resolve the fixed link flow control using the recently introduced linkmode_resolve_pause() helper, which we use in phylink_get_fixed_state() only when operating in full duplex mode.

2020-02-16net: add linkmode helper for setting flow control advertisementRussell King
Add a linkmode helper to set the flow control advertisement in an ethtool linkmode mask according to the tx/rx capabilities. This implementation is moved from phylib, and documented with an analysis of its shortcomings.

2020-02-16net: add helpers to resolve negotiated flow controlRussell King
Add a couple of helpers to resolve negotiated flow control. Two helpers are provided: - linkmode_resolve_pause() which takes the link partner and local advertisements, and decodes whether we should enable TX or RX pause at the MAC. This is useful outside of phylib, e.g. in phylink. - phy_get_pause(), which returns the TX/RX enablement status for the current negotiation results of the PHY. This allows us to centralise the flow control resolution, rather than spreading it around.

2020-02-16net: linkmode: make linkmode_test_bit() take const pointerRussell King
linkmode_test_bit() does not modify the address; test_bit() is also declared const volatile for the same reason. There's no need for linkmode_test_bit() to be any different, and allows implementation of helpers that take a const linkmode pointer.

2020-02-16openvswitch: add TTL decrement actionMatteo Croce
New action to decrement TTL instead of setting it to a fixed value. This action will decrement the TTL and, in case of expired TTL, drop it or execute an action passed via a nested attribute. The default TTL expired action is to drop the packet. Supports both IPv4 and IPv6 via the ttl and hop_limit fields, respectively. Tested with a corresponding change in the userspace: # ovs-dpctl dump-flows in_port(2),eth(),eth_type(0x0800), packets:0, bytes:0, used:never, actions:dec_ttl{ttl<=1 action:(drop)},1 in_port(1),eth(),eth_type(0x0800), packets:0, bytes:0, used:never, actions:dec_ttl{ttl<=1 action:(drop)},2 in_port(1),eth(),eth_type(0x0806), packets:0, bytes:0, used:never, actions:2 in_port(2),eth(),eth_type(0x0806), packets:0, bytes:0, used:never, actions:1 # ping -c1 192.168.0.2 -t 42 IP (tos 0x0, ttl 41, id 61647, offset 0, flags [DF], proto ICMP (1), length 84) 192.168.0.1 > 192.168.0.2: ICMP echo request, id 386, seq 1, length 64 # ping -c1 192.168.0.2 -t 120 IP (tos 0x0, ttl 119, id 62070, offset 0, flags [DF], proto ICMP (1), length 84) 192.168.0.1 > 192.168.0.2: ICMP echo request, id 388, seq 1, length 64 # ping -c1 192.168.0.2 -t 1 # Co-developed-by: Bindiya Kurle <bindiyakurle@gmail.com> Signed-off-by: Bindiya Kurle <bindiyakurle@gmail.com> Signed-off-by: Matteo Croce <mcroce@redhat.com> Acked-by: Pravin B Shelar <pshelar@ovn.org> Signed-off-by: David S.

2020-02-16net: export netdev_next_lower_dev_rcu()Taehee Yoo
netdev_next_lower_dev_rcu() will be used to implement a function, which is to walk all lower interfaces. There are already functions that they walk their lower interface. (netdev_walk_all_lower_dev_rcu, netdev_walk_all_lower_dev()). But, there would be cases that couldn't be covered by given netdev_walk_all_lower_dev_{rcu}() function. So, some modules would want to implement own function, which is to walk all lower interfaces. In the next patch, netdev_next_lower_dev_rcu() will be used. In addition, this patch removes two unused prototypes in netdevice.h. Signed-off-by: Taehee Yoo <ap420073@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-02-16tcp-zerocopy: Return sk_err (if set) along with tcp receive zerocopy.Arjun Roy
This patchset is intended to reduce the number of extra system calls imposed by TCP receive zerocopy. For ping-pong RPC style workloads, this patchset has demonstrated a system call reduction of about 30% when coupled with userspace changes. For applications using epoll, returning sk_err along with the result of tcp receive zerocopy could remove the need to call recvmsg()=-EAGAIN after a spurious wakeup. Consider a multi-threaded application using epoll. A thread may awaken with EPOLLIN but another thread may already be reading. The spuriously-awoken thread does not necessarily know that another thread 'won'; rather, it may be possible that it was woken up due to the presence of an error if there is no data. A zerocopy read receiving 0 bytes thus would need to be followed up by recvmsg to be sure. Instead, we return sk_err directly with zerocopy, so the application can avoid this extra system call.

2020-02-16tcp-zerocopy: Return inq along with tcp receive zerocopy.Arjun Roy
This patchset is intended to reduce the number of extra system calls imposed by TCP receive zerocopy. For ping-pong RPC style workloads, this patchset has demonstrated a system call reduction of about 30% when coupled with userspace changes. For applications using edge-triggered epoll, returning inq along with the result of tcp receive zerocopy could remove the need to call recvmsg()=-EAGAIN after a successful zerocopy. Generally speaking, since normally we would need to perform a recvmsg() call for every successful small RPC read via TCP receive zerocopy, returning inq can reduce the number of system calls performed by approximately half.

The rawmidi state flags (opened, append, active_sensing) are stored in bit fields that can be potentially racy when concurrently accessed without any locks. Although the current code should be fine, there is also no any real benefit by keeping the bitfields for this kind of short number of members. This patch changes those bit fields flags to the simple bool fields. There should be no size increase of the snd_rawmidi_substream by this change.

This patch adds a new element to wiphy allowing a driver to set a custom tx_queue_len and the code that will apply it in case it is set. The current default is 1000 which is too low for ath11k when doing HE rates.

2020-02-14mac80211: Fix setting txpower to zeroBen Greear
With multiple VIFS ath10k, and probably others, tries to find the minimum txpower for all vifs and uses that when setting txpower in the firmware. If a second vif is added and starts to scan, it's txpower is not initialized yet and it set to zero. ath10k had a patch to ignore zero values, but then it is impossible to actually set txpower to zero. So, instead initialize the txpower to INT_MIN in mac80211, and let drivers know that means the power has not been set and so should be ignored. This should fix regression in: commit 88407beb1b1462f706a1950a355fd086e1c450b6 Author: Ryan Hsu <ryanhsu@qca.qualcomm.com> Date: Tue Dec 13 14:55:19 2016 -0800 ath10k: fix incorrect txpower set by P2P_DEVICE interface Tested on ath10k 9984 with ath10k-ct firmware.

2020-02-13drm: Add support for DP 1.4 Compliance edid corruption testJerry (Fangzhi) Zuo
Unlike DP 1.2 edid corruption test, DP 1.4 requires to calculate real CRC value of the last edid data block, and write it back. Current edid CRC calculates routine adds the last CRC byte, and check if non-zero. This behavior is not accurate; actually, we need to return the actual CRC value when corruption is detected. This commit changes this issue by returning the calculated CRC, and initiate the required sequence. Change since v7 - Fix for CI.CHECKPATCH Change since v6 - Add return check Change since v5 - Obtain real CRC value before dumping bad edid Change since v4 - Fix for CI.CHECKPATCH Change since v3 - Fix a minor typo. Change since v2 - Rewrite checksum computation routine to avoid duplicated code. - Rename to avoid confusion. Change since v1 - Have separate routine for returning real CRC.

2020-02-13icmp: introduce helper for nat'd source address in network device contextJason A. Donenfeld
This introduces a helper function to be called only by network drivers that wraps calls to icmp[v6]_send in a conntrack transformation, in case NAT has been used. We don't want to pollute the non-driver path, though, so we introduce this as a helper to be called by places that actually make use of this, as suggested by Florian. Signed-off-by: Jason A.
