* net: Get rid of switchdev_port_attr_get()Florian Fainelli2019-02-211-1/+1
| | | | | | | | | | | | | | With the bridge no longer calling switchdev_port_attr_get() to obtain the supported bridge port flags from a driver but instead trying to set the bridge port flags directly and relying on driver to reject unsupported configurations, we can effectively get rid of switchdev_port_attr_get() entirely since this was the only place where it was called.

* net: Remove SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS_SUPPORTFlorian Fainelli2019-02-211-4/+2
| | | | | | | | | | | | Now that we have converted the bridge code and the drivers to check for bridge port(s) flags at the time we try to set them, there is no need for a get() -> set() sequence anymore and SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS_SUPPORT therefore becomes unused.

|\| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The netfilter conflicts were rather simple overlapping changes. However, the cls_tcindex.c stuff was a bit more complex. On the 'net' side, Cong is fixing several races and memory leaks. Whilst on the 'net-next' side we have Vlad adding the rtnl-ness support. What I've decided to do, in order to resolve this, is revert the conversion over to using a workqueue that Cong did, bringing us back to pure RCU. I did it this way because I believe that either Cong's races don't apply with have Vlad did things, or Cong will have to implement the race fix slightly differently. Signed-off-by: David S.

As we will bring up different features and use cases to upstream in different patch series, it will leave some intermediate kernel versions which support partial features. Hence, end user might run into problems when they use such kernels on bare metals or virtualization environments. This leaves scalable mode default off and end users could turn it on with "intel-iommu=sm_on" only when they have clear ideas about which scalable features are supported in the kernel.

It just reports the total number of dentries in the LRU lists. As excessive number of negative dentries can have an impact on system performance, it will be wise to track the number of positive and negative dentries separately. This patch adds tracking for the total number of negative dentries in the system LRU lists and reports it in the 5th field in the /proc/sys/fs/dentry-state file. The number, however, does not include negative dentries that are in flight but not in the LRU yet as well as those in the shrinker lists which are on the way out anyway. The number of positive dentries in the LRU lists can be roughly found by subtracting the number of negative dentries from the unused count. Matthew Wilcox had confirmed that since the introduction of the dentry_stat structure in 2.1.60, the dummy array was there, probably for future extension. They were not replacements of pre-existing fields. So no sane applications that read the value of /proc/sys/fs/dentry-state will do dummy thing if the last 2 fields of the sysctl parameter are not zero. IOW, it will be safe to use one of the dummy array entry for negative dentry count. Signed-off-by: Waiman Long <longman@redhat.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

The main changes are: 1) Add a riscv64 JIT for BPF, from Björn. 2) Implement BTF deduplication algorithm for libbpf which takes BTF type information containing duplicate per-compilation unit information and reduces it to an equivalent set of BTF types with no duplication and without loss of information, from Andrii. 3) Offloaded and native BPF XDP programs can coexist today, enable also offloaded and generic ones as well, from Jakub. 4) Expose various BTF related helper functions in libbpf as API which are in particular helpful for JITed programs, from Yonghong. 5) Fix the recently added JMP32 code emission in s390x JIT, from Heiko. 6) Fix BPF kselftests' tcp_{server,client}.py to be able to run inside a network namespace, also add a fix for libbpf to get libbpf_print() working, from Stanislav. 7) Fixes for bpftool documentation, from Prashant. 8) Type cleanup in BPF kselftests' test_maps.c to silence a gcc8 warning, from Breno. ==================== Signed-off-by: David S.

Any new users should create a proper device and pass the GPIO as a descriptor associated with the device so delete the GPIO argument from the calls and drop the code looking requesting a GPIO in fixed_phy_add(). In fixed phy_register(), investigate the "fixed-link" node and pick the GPIO descriptor from "link-gpios" if this property exists. Move the corresponding code out of of_mdio.c as the fixed phy code anyways requires OF to be in use.

The main changes are: 1) Teach verifier dead code removal, this also allows for optimizing / removing conditional branches around dead code and to shrink the resulting image. Code store constrained architectures like nfp would have hard time doing this at JIT level, from Jakub. 2) Add JMP32 instructions to BPF ISA in order to allow for optimizing code generation for 32-bit sub-registers. Evaluation shows that this can result in code reduction of ~5-20% compared to 64 bit-only code generation. Also add implementation for most JITs, from Jiong. 3) Add support for __int128 types in BTF which is also needed for vmlinux's BTF conversion to work, from Yonghong. 4) Add a new command to bpftool in order to dump a list of BPF-related parameters from the system or for a specific network device e.g. in terms of available prog/map types or helper functions, from Quentin. 5) Add AF_XDP sock_diag interface for querying sockets from user space which provides information about the RX/TX/fill/completion rings, umem, memory usage etc, from Björn. 6) Add skb context access for skb_shared_info->gso_segs field, from Eric. 7) Add support for testing flow dissector BPF programs by extending existing BPF_PROG_TEST_RUN infrastructure, from Stanislav. 8) Split BPF kselftest's test_verifier into various subgroups of tests in order better deal with merge conflicts in this area, from Jakub. 9) Add support for queue/stack manipulations in bpftool, from Stanislav. 10) Document BTF, from Yonghong. 11) Dump supported ELF section names in libbpf on program load failure, from Taeung. 12) Silence a false positive compiler warning in verifier's BTF handling, from Peter. 13) Fix help string in bpftool's feature probing, from Prashant. 14) Remove duplicate includes in BPF kselftests, from Yue. ==================== Signed-off-by: David S.
