git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull SPDX update from Greg KH: "Here is a series of patches that add SPDX tags to different kernel files, based on two different things: - SPDX entries are added to a bunch of files that we missed a year ago that do not have any license information at all. These were either missed because the tool saw the MODULE_LICENSE() tag, or some EXPORT_SYMBOL tags, and got confused and thought the file had a real license, or the files have been added since the last big sweep, or they were Makefile/Kconfig files, which we didn't touch last time. - Add GPL-2.0-only or GPL-2.0-or-later tags to files where our scan tools can determine the license text in the file itself. Where this happens, the license text is removed, in order to cut down on the 700+ different ways we have in the kernel today, in a quest to get rid of all of these. These patches have been out for review on the linux-spdx@vger mailing list, and while they were created by automatic tools, they were hand-verified by a bunch of different people, all whom names are on the patches are reviewers. The reason for these "large" patches is if we were to continue to progress at the current rate of change in the kernel, adding license tags to individual files in different subsystems, we would be finished in about 10 years at the earliest. There will be more series of these types of patches coming over the next few weeks as the tools and reviewers crunch through the more "odd" variants of how to say "GPLv2" that developers have come up with over the years, combined with other fun oddities (GPL + a BSD disclaimer?) that are being unearthed, with the goal for the whole kernel to be cleaned up. These diffstats are not small, 3840 files are touched, over 10k lines removed in just 24 patches" * tag 'spdx-5.2-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (24 commits) treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 25 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 24 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 23 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 22 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 21 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 20 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 19 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 18 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 17 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 15 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 14 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 13 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 12 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 11 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 10 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 9 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 7 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 5 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 4 treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 3 ...

Flow destination comparison has an inaccuracy: code see no difference between same vf ports, which belong to different pfs. Example: If start ping from VF0 (PF1) to VF1 (PF1) and mirror all traffic to VF0 (PF2), icmp reply to VF0 (PF1) and mirrored flow to VF0 (PF2) would be determined as same destination. It lead to creating flow handler with rule nodes, which not added to node tree. When later driver try to delete this flow rules we got kernel crash. Add comparison of vhca_id field to avoid this.

To avoid any ambiguity between vport index and vport number, rename functions that had vport, to vport_num or vport_index appropriately. vport_num is u16 hence change mlx5_eswitch_index_to_vport_num() return type to u16. vport_index is an int in vport array. Hence change input type of vport index in mlx5_eswitch_index_to_vport_num() to int. Correct multiple eswitch representor interfaces use type u16 of rep->vport as type int vport_index. Send vport FW commands with correct eswitch u16 vport_num instead host int vport_index.

2019-05-01net/mlx5: E-Switch, Use atomic rep state to serialize state changeBodong Wang
When the state of rep was introduced, it was also designed to prevent duplicate unloading of the same rep. Considering the following two flows when an eswitch manager is at switchdev mode with n VF reps loaded. +--------------------------------------+--------------------------------+ | cpu-0 | cpu-1 | | -------- | -------- | | mlx5_ib_remove | mlx5_eswitch_disable_sriov | | mlx5_ib_unregister_vport_reps | esw_offloads_cleanup | | mlx5_eswitch_unregister_vport_reps | esw_offloads_unload_all_reps | | __unload_reps_all_vport | __unload_reps_all_vport | +--------------------------------------+--------------------------------+ These two flows will try to unload the same rep. Per original design, once one flow unloads the rep, the state moves to REGISTERED. The 2nd flow will no longer needs to do the unload and bails out. However, as read and write of the state is not atomic, when 1st flow is doing the unload, the state is still LOADED, 2nd flow is able to do the same unload action. Kernel crash will happen. To solve this, driver should do atomic test-and-set for the state. So that only one flow can change the rep state from LOADED to REGISTERED, and proceed to do the actual unloading. Since the state is changing to atomic type, all other read/write should be atomic action as well.

2019-05-01net/mlx5: E-Switch, Fix the check of legal vportBodong Wang
The check of legal vport is to ensure the vport number falls between 0 and total number of vports. Along with the introduction of uplink rep, enabled vports are not consecutive any more. Therefore, rely on the eswitch vport getter function to check if it's a valid vport. As the getter function relies on eswitch, add the check of vport group manager and validation the presence of eswitch structure. Remove the redundant check in the function calls. Since the vport array will be allocated once eswitch is initialized and will be kept alive if eswitch presents, no need to protect it with the state lock.

With unlocked TC it is possible to have spurious deletes and inserts of same filter.

Fix mlx5e_configure_flower() to return -EEXIST when TC tries to insert a filter that is already provisioned to the driver.

Currently mlx5 core stores copy of the PCI device name in a mlx5_priv structure and uses pr_warn, pr_err helpers. Get rid of the copy of this name; instead store the parent device pointer that contains name as well as dma specific parameters. This also allows to use kernel's well defined dev_warn, dev_err, dev_dbg device specific print routines. This is also a preparation patch to access non PCI parent device in future.

Daniel Borkmann says: ==================== pull-request: bpf-next 2019-04-28 The following pull-request contains BPF updates for your *net-next* tree. The main changes are: 1) Introduce BPF socket local storage map so that BPF programs can store private data they associate with a socket (instead of e.g. separate hash table), from Martin. 2) Add support for bpftool to dump BTF types. This is done through a new `bpftool btf dump` sub-command, from Andrii. 3) Enable BPF-based flow dissector for skb-less eth_get_headlen() calls which was currently not supported since skb was used to lookup netns, from Stanislav. 4) Add an opt-in interface for tracepoints to expose a writable context for attached BPF programs, used here for NBD sockets, from Matt. 5) BPF xadd related arm64 JIT fixes and scalability improvements, from Daniel. 6) Change the skb->protocol for bpf_skb_adjust_room() helper in order to support tunnels such as sit.
