2019-07-05ACPI / APEI: Remove needless __ghes_check_estatus() callsLiguang Zhang
Function __ghes_check_estatus() is always called after __ghes_peek_estatus(), but it is already called in __ghes_peek_estatus(). So we should remove some needless __ghes_check_estatus() calls.

2019-07-04net/mlx5: Added devlink info callbackShay Agroskin
The callback is invoked using 'devlink dev info <pci>' command and returns the running and pending firmware version of the HCA and the name of the kernel driver. If there is a pending firmware version (a new version is burned but the HCA still runs with the previous) it is returned as the stored firmware version. Otherwise, the running version is returned for this field. Output example: $ devlink dev info pci/0000:00:06.0 pci/0000:00:06.0: driver mlx5_core versions: fixed: fw.psid MT_0000000009 running: fw.version 16.26.0100 stored: fw.version 16.26.0100 Signed-off-by: Shay Agroskin <shayag@mellanox.com> Reviewed-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
2019-07-04net/mlx5: Added fw version query commandShay Agroskin
Using the MCQI and MCQS registers, we query the running and pending fw version of the HCA. The MCQS is queried with sequentially increasing component index, until a component of type BOOT_IMG is found. Querying this component's version using the MCQI register yields the running and pending fw version of the HCA. Querying MCQI for the pending fw version should be done only after validating that such fw version exists. This is done my checking 'component update state' field in MCQS output.

Daniel Borkmann says: ==================== pull-request: bpf-next 2019-07-03 The following pull-request contains BPF updates for your *net-next* tree. There is a minor merge conflict in mlx5 due to 8960b38932be ("linux/dim: Rename externally used net_dim members") which has been pulled into your tree in the meantime, but resolution seems not that bad ... getting current bpf-next out now before there's coming more on mlx5. ;) I'm Cc'ing Saeed just so he's aware of the resolution below: ** First conflict in drivers/net/ethernet/mellanox/mlx5/core/en_main.c: <<<<<<< HEAD static int mlx5e_open_cq(struct mlx5e_channel *c, struct dim_cq_moder moder, struct mlx5e_cq_param *param, struct mlx5e_cq *cq) ======= int mlx5e_open_cq(struct mlx5e_channel *c, struct net_dim_cq_moder moder, struct mlx5e_cq_param *param, struct mlx5e_cq *cq) >>>>>>> e5a3e259ef239f443951d401db10db7d426c9497 Resolution is to take the second chunk and rename net_dim_cq_moder into dim_cq_moder. Also the signature for mlx5e_open_cq() in ... drivers/net/ethernet/mellanox/mlx5/core/en.h +977 ... and in mlx5e_open_xsk() ... drivers/net/ethernet/mellanox/mlx5/core/en/xsk/setup.c +64 ... needs the same rename from net_dim_cq_moder into dim_cq_moder. ** Second conflict in drivers/net/ethernet/mellanox/mlx5/core/en_main.c: <<<<<<< HEAD int cpu = cpumask_first(mlx5_comp_irq_get_affinity_mask(priv->mdev, ix)); struct dim_cq_moder icocq_moder = {0, 0}; struct net_device *netdev = priv->netdev; struct mlx5e_channel *c; unsigned int irq; ======= struct net_dim_cq_moder icocq_moder = {0, 0}; >>>>>>> e5a3e259ef239f443951d401db10db7d426c9497 Take the second chunk and rename net_dim_cq_moder into dim_cq_moder as well. Let me know if you run into any issues. Anyway, the main changes are: 1) Long-awaited AF_XDP support for mlx5e driver, from Maxim. 2) Addition of two new per-cgroup BPF hooks for getsockopt and setsockopt along with a new sockopt program type which allows more fine-grained pass/reject settings for containers. Also add a sock_ops callback that can be selectively enabled on a per-socket basis and is executed for every RTT to help tracking TCP statistics, both features from Stanislav. 3) Follow-up fix from loops in precision tracking which was not propagating precision marks and as a result verifier assumed that some branches were not taken and therefore wrongly removed as dead code, from Alexei. 4) Fix BPF cgroup release synchronization race which could lead to a double-free if a leaf's cgroup_bpf object is released and a new BPF program is attached to the one of ancestor cgroups in parallel, from Roman. 5) Support for bulking XDP_TX on veth devices which improves performance in some cases by around 9%, from Toshiaki. 6) Allow for lookups into BPF devmap and improve feedback when calling into bpf_redirect_map() as lookup is now performed right away in the helper itself, from Toke. 7) Add support for fq's Earliest Departure Time to the Host Bandwidth Manager (HBM) sample BPF program, from Lawrence. 8) Various cleanups and minor fixes all over the place from many others. ==================== Signed-off-by: David S.

2019-07-04net: ethernet: mediatek: Fix overlapping capability bits.René van Dorst
Both MTK_TRGMII_MT7621_CLK and MTK_PATH_BIT are defined as bit 10. This can causes issues on non-MT7621 devices which has the MTK_PATH_BIT(MTK_ETH_PATH_GMAC1_RGMII) and MTK_TRGMII capability set. The wrong TRGMII setup code can be executed. The current wrongly executed code doesn’t do any harm on MT7623 and the TRGMII setup for the MT7623 SOC side is done in MT7530 driver So it wasn’t noticed in the test. Move all capability bits in one enum so that they are all unique and easy to expand in the future. Because mtk_eth_path enum is merged in to mkt_eth_capabilities, the variable path value is no longer between 0 to number of paths, mtk_eth_path_name can’t be used anymore in this form. Convert the mtk_eth_path_name array to a function to lookup the pathname. The old code walked thru the mtk_eth_path enum, which is also merged with mkt_eth_capabilities. Expand array mtk_eth_muxc so it can store the name and capability bit of the mux. Convert the code so it can walk thru the mtk_eth_muxc array.

2019-07-04bonding: add an option to specify a delay between peer notificationsVincent Bernat
Currently, gratuitous ARP/ND packets are sent every `miimon' milliseconds. This commit allows a user to specify a custom delay through a new option, `peer_notif_delay'. Like for `updelay' and `downdelay', this delay should be a multiple of `miimon' to avoid managing an additional work queue. The configuration logic is copied from `updelay' and `downdelay'. However, the default value cannot be set using a module parameter: Netlink or sysfs should be used to configure this feature. When setting `miimon' to 100 and `peer_notif_delay' to 500, we can observe the 500 ms delay is respected: 20:30:19.354693 ARP, Request who-has 203.0.113.10 tell 203.0.113.10, length 28 20:30:19.874892 ARP, Request who-has 203.0.113.10 tell 203.0.113.10, length 28 20:30:20.394919 ARP, Request who-has 203.0.113.10 tell 203.0.113.10, length 28 20:30:20.914963 ARP, Request who-has 203.0.113.10 tell 203.0.113.10, length 28 In bond_mii_monitor(), I have tried to keep the lock logic readable. The change is due to the fact we cannot rely on a notification to lower the value of `bond->send_peer_notif' as `NETDEV_NOTIFY_PEERS' is only triggered once every N times, while we need to decrement the counter each time. iproute2 also needs to be updated to be able to specify this new attribute through `ip link'.

On PPC64, flush_dcache_range() only does a writeback while flush_inval_dcache_range() does the invalidation in addition. In addition it looks like within arch/powerpc/, there are no PPC64 platforms using flush_dcache_range() This patch drops the existing 64 bits version of flush_dcache_range() and renames flush_inval_dcache_range() into flush_dcache_range().

Coresight platform support assumes that a missing "cpu" phandle defaults to CPU0. This could be problematic and unnecessarily binds components to CPU0, where they may not be. In coresight etm and cpu-debug drivers, abort the probe for such cases.

2019-07-04drm/imx: notify drm core before sending event during crtc disableRobert Beckett
Notify drm core before sending pending events during crtc disable. This fixes the first event after disable having an old stale timestamp by having drm_crtc_vblank_off update the timestamp to now. This was seen while debugging weston log message: Warning: computed repaint delay is insane: -8212 msec This occurred due to: 1. driver starts up 2. fbcon comes along and restores fbdev, enabling vblank 3. vblank_disable_fn fires via timer disabling vblank, keeping vblank seq number and time set at current value (some time later) 4. weston starts and does a modeset 5. atomic commit disables crtc while it does the modeset 6. ipu_crtc_atomic_disable sends vblank with old seq number and time Fixes: a474478642d5 ("drm/imx: fix crtc vblank state regression") Signed-off-by: Robert Beckett <bob.beckett@collabora.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
2019-07-04reset: remove redundant null check on pointer devColin Ian King
Pointer dev is being dereferenced when passed to the inlined functon dev_name, however, dev is later being null checked so at first this seems like a potential null pointer dereference. In fact, _reset_control_get_from_lookup is only ever called from __reset_control_get, right after checking dev->of_node hence dev can never be null. Clean this up by removing the redundant null check. Thanks to Philipp Zabel for spotting that dev can never be null.

2019-07-04i3c: master: Use struct_size() helperGustavo A. R. Silva
Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes, in particular in the context in which this code is being used. So, replace the following form: sizeof(*defslvs) + ((ndevs - 1) * sizeof(struct i3c_ccc_dev_desc)) with: struct_size(defslvs, slaves, ndevs - 1) This code was detected with the help of Coccinelle.

After recent hibernation-related changes, there are no more callers of dev_pm_skip_next_resume_phases() except for the PM core itself in which it is more straightforward to run the statements from that function directly, so do that and drop it.

2019-07-04PM / QOS: Rename __dev_pm_qos_read_value() and dev_pm_qos_raw_read_value()Viresh Kumar
dev_pm_qos_read_value() will soon need to support more constraint types (min/max frequency) and will have another argument to it, i.e. type of the constraint. While that is fine for the existing users of dev_pm_qos_read_value(), but not that optimal for the callers of __dev_pm_qos_read_value() and dev_pm_qos_raw_read_value() as all the callers of these two routines are only looking for resume latency constraint. Lets make these two routines care only about the resume latency constraint and rename them to __dev_pm_qos_resume_latency() and dev_pm_qos_raw_resume_latency(). Suggested-by: Rafael J.
