2022-02-28igc: igc_write_phy_reg_gpy: drop premature returnSasha Neftin1-2/+0
Similar to "igc_read_phy_reg_gpy: drop premature return" patch. igc_write_phy_reg_gpy checks the return value from igc_write_phy_reg_mdic and if it's not 0, returns immediately. By doing this, it leaves the HW semaphore in the acquired state. Drop this premature return statement, the function returns after releasing the semaphore immediately anyway.

2022-02-28libbpf: Fix BPF_MAP_TYPE_PERF_EVENT_ARRAY auto-pinningStijn Tintel1-19/+25
When a BPF map of type BPF_MAP_TYPE_PERF_EVENT_ARRAY doesn't have the max_entries parameter set, the map will be created with max_entries set to the number of available CPUs. When we try to reuse such a pinned map, map_is_reuse_compat will return false, as max_entries in the map definition differs from max_entries of the existing map, causing the following error: libbpf: couldn't reuse pinned map at '/sys/fs/bpf/m_logging': parameter mismatch Fix this by overwriting max_entries in the map definition. For this to work, we need to do this in bpf_object__create_maps, before calling bpf_object__reuse_map.

2022-02-28bpf, selftests: Use raw_tp program for atomic testHou Tao2-83/+36
Now atomic tests will attach fentry program and run it through bpf_prog_test_run_opts(), but attaching fentry program depends on BPF trampoline which is only available under x86-64.

2022-02-28bpf, arm64: Support more atomic operationsHou Tao2-45/+217
Atomics for eBPF patch series adds support for atomic[64]_fetch_add, atomic[64]_[fetch_]{and,or,xor} and atomic[64]_{xchg|cmpxchg}, but it only adds support for x86-64, so support these atomic operations for arm64 as well. Basically the implementation procedure is almost mechanical translation of code snippets in atomic_ll_sc.h & atomic_lse.h & cmpxchg.h located under arch/arm64/include/asm. When LSE atomic is unavailable, an extra temporary register is needed for (BPF_ADD | BPF_FETCH) to save the value of src register, instead of adding TMP_REG_4 just use BPF_REG_AX instead. Also make emit_lse_atomic() as an empty inline function when CONFIG_ARM64_LSE_ATOMICS is disabled. For cpus_have_cap(ARM64_HAS_LSE_ATOMICS) case and no-LSE-ATOMICS case, the following three tests: "./test_verifier", "./test_progs -t atomic" and "insmod ./test_bpf.ko" are exercised and passed.

2022-02-28SUNRPC: Teach server to recognize RPC_AUTH_TLSChuck Lever3-0/+63
Initial support for the RPC_AUTH_TLS authentication flavor enables NFSD to eventually accept an RPC_AUTH_TLS probe from clients. This patch simply prevents NFSD from rejecting these probes completely. In the meantime, graft this support in now so that RPC_AUTH_TLS support keeps up with generic code and API changes in the RPC server. Down the road, server-side transport implementations will populate xpo_start_tls when they can support RPC-with-TLS. For example, TCP will eventually populate it, but RDMA won't.

2022-02-28SUNRPC: Remove the .svo_enqueue_xprt methodChuck Lever6-13/+5
We have never been able to track down and address the underlying cause of the performance issues with workqueue-based service support. svo_enqueue_xprt is called multiple times per RPC, so it adds instruction path length, but always ends up at the same function: svc_xprt_do_enqueue(). We do not anticipate needing this flexibility for dynamic nfsd thread management support. As a micro-optimization, remove .svo_enqueue_xprt because Spectre/Meltdown makes virtual function calls more costly.

2022-02-28NFS: Return valid errors from nfs2/3_decode_dirent()Trond Myklebust2-16/+7
Valid return values for decode_dirent() callback functions are: 0: Success -EBADCOOKIE: End of directory -EAGAIN: End of xdr_stream All errors need to map into one of those three values.

2022-02-28drm/bridge: it6505: Fix the read buffer array boundHsin-Yi Wang1-2/+2
The size of read_buf is READ_BUFFER_SIZE (200), so we can't access it with read_buf + PAGE_SIZE (4096). Extend the READ_BUFFER_SIZE to 400 and set the end position to read_buf + READ_BUFFER_SIZE.
