We should not clear FLAGS_DMA_ACTIVE before omap_sham_update_dma_stop() is done calling dma_unmap_sg(). We already clear FLAGS_DMA_ACTIVE at the end of omap_sham_update_dma_stop(). The early clearing of FLAGS_DMA_ACTIVE is not causing issues as we do not need to defer anything based on FLAGS_DMA_ACTIVE currently. So this can be applied as clean-up.

ecdsa_set_pub_key() makes an u64 pointer at 1 byte offset of the key. This results in an unaligned u64 pointer. This pointer is passed to ecc_swap_digits() which assumes natural alignment.

The kfree_sensitive is a kernel API to clear sensitive information that should not be leaked to other future users of the same memory objects and free the memory. Its function is the same as the combination of memzero_explicit and kfree. Thus, we can replace the combination APIs with the single kfree_sensitive API. Signed-off-by:

The tdes dev gets allocated to the tfm at alg->init time, there's no need to overwrite the pointer to tdes_dd afterwards. There's a single IP per SoC anyway, the first entry from the atmel_tdes.dev_list is chosen without counting for tfms for example, in case one thinks of an even distribution of tfms across the TDES IPs: there's only one. At alg->init time the ctx->dd should already be NULL, there's no need to check its value before requesting for a tdes dev. Signed-off-by:

This patch adds AES-NI/AVX/x86_64 assembler implementation of SM4 block cipher. Through two affine transforms, we can use the AES S-Box to simulate the SM4 S-Box to achieve the effect of instruction acceleration. The main algorithm implementation comes from SM4 AES-NI work by libgcrypt and Markku-Juhani O. Saarinen at: https://github.com/mjosaarinen/sm4ni This optimization supports the four modes of SM4, ECB, CBC, CFB, and CTR. Since CBC and CFB do not support multiple block parallel encryption, the optimization effect is not obvious. Benchmark on Intel Xeon Cascadelake, the data comes from the 218 mode and 518 mode of tcrypt. The abscissas are blocks of different lengths. The data is tabulated and the unit is Mb/s: sm4-generic | 16 64 128 256 1024 1420 4096 ECB enc | 40.99 46.50 48.05 48.41 49.20 49.25 49.28 ECB dec | 41.07 46.99 48.15 48.67 49.20 49.25 49.29 CBC enc | 37.71 45.28 46.77 47.60 48.32 48.37 48.40 CBC dec | 36.48 44.82 46.43 47.45 48.23 48.30 48.36 CFB enc | 37.94 44.84 46.12 46.94 47.57 47.46 47.68 CFB dec | 37.50 42.84 43.74 44.37 44.85 44.80 44.96 CTR enc | 39.20 45.63 46.75 47.49 48.09 47.85 48.08 CTR dec | 39.64 45.70 46.72 47.47 47.98 47.88 48.06 sm4-aesni-avx ECB enc | 33.75 134.47 221.64 243.43 264.05 251.58 258.13 ECB dec | 34.02 134.92 223.11 245.14 264.12 251.04 258.33 CBC enc | 38.85 46.18 47.67 48.34 49.00 48.96 49.14 CBC dec | 33.54 131.29 223.88 245.27 265.50 252.41 263.78 CFB enc | 38.70 46.10 47.58 48.29 49.01 48.94 49.19 CFB dec | 32.79 128.40 223.23 244.87 265.77 253.31 262.79 CTR enc | 32.58 122.23 220.29 241.16 259.57 248.32 256.69 CTR dec | 32.81 122.47 218.99 241.54 258.42 248.58 256.61 Signed-off-by:

Take the existing small footprint and mostly time invariant C code and turn it into a SM4 library that can be used for non-performance critical, casual use of SM4, and as a fallback for, e.g., SIMD code that needs a secondary path that can be taken in contexts where the SIMD unit is off limits. Secondly, some codes have been optimized, such as unrolling small times loop, removing unnecessary memory shifts, exporting sbox, fk, ck arrays, and basic encryption and decryption functions.

The kernel recovers in due course from missing Mlocked pages: but there was no point in calling page_mlock() (formerly known as try_to_munlock()) on a THP, because nothing got done even when it was found to be mapped in another VM_LOCKED vma. It's true that we need to be careful: Mlocked accounting of pte-mapped THPs is too difficult (so consistently avoided); but Mlocked accounting of only-pmd-mapped THPs is supposed to work, even when multiple mappings are mlocked and munlocked or munmapped. Refine the tests. There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so page_mlock_one() does not even have to worry about that complication. (I said the kernel recovers: but would page reclaim be likely to split THP before rediscovering that it's VM_LOCKED? I've not followed that up) Fixes: 9a73f61b ("thp, mlock: do not mlock PTE-mapped file huge pages") Signed-off-by:

Merge tag 'perf-tools-for-v5.14-2021-07-10' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux Pull more perf tool updates from Arnaldo Carvalho de Melo: "New features: - Enable use of BPF counters with 'perf stat --for-each-cgroup', using per-CPU 'cgroup-switch' events with an attached BPF program that does aggregation per-cgroup in the kernel instead of using per-cgroup perf events. - Add Topdown metrics L2 events as default events in 'perf stat' for systems having those events. Hardware tracing: - Add a config for max loops without consuming a packet in the Intel PT packet decoder, set via 'perf config intel-pt.max-loops=N' Hardware enablement: - Disable misleading NMI watchdog message in 'perf stat' on hybrid systems such as Intel Alder Lake. - Add a dummy event on hybrid systems to collect metadata records. - Add 24x7 nest metric events for the Power10 platform. Fixes: - Fix event parsing for PMUs starting with the same prefix. - Fix the 'perf trace' 'trace' alias installation dir. - Fix buffer size to report iregs in perf script python scripts, supporting the extended registers in PowerPC. - Fix overflow in elf_sec__is_text(). - Fix 's' on source line when disasm is empty in the annotation TUI, accessible via 'perf annotate', 'perf report' and 'perf top'. - Plug leaks in scandir() returned dirent entries in 'perf test' when sorting the shell tests. - Fix --task and --stat with pipe input in 'perf report'. - Fix 'perf probe' use of debuginfo files by build id. - If a DSO has both dynsym and symtab ELF sections, read from both when loading the symbol table, fixing a problem processing Fedora 32 glibc DSOs. Libraries: - Add grouping of events to libperf, from code in tools/perf, allowing libperf users to use that mode. Misc: - Filter plt stubs from the 'perf probe --functions' output. - Update UAPI header copies for asound, DRM, mman-common.h and the ones affected by the quotactl_fd syscall" * tag 'perf-tools-for-v5.14-2021-07-10' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux: (29 commits) perf test: Add free() calls for scandir() returned dirent entries libperf: Add tests for perf_evlist__set_leader() libperf: Remove BUG_ON() from library code in get_group_fd() libperf: Add group support to perf_evsel__open() perf tools: Fix pattern matching for same substring in different PMU type perf record: Add a dummy event on hybrid systems to collect metadata records perf stat: Add Topdown metrics L2 events as default events libperf: Adopt evlist__set_leader() from tools/perf as perf_evlist__set_leader() libperf: Move 'nr_groups' from tools/perf to evlist::nr_groups libperf: Move 'leader' from tools/perf to perf_evsel::leader libperf: Move 'idx' from tools/perf to perf_evsel::idx libperf: Change tests to single static and shared binaries perf intel-pt: Add a config for max loops without consuming a packet perf stat: Disable the NMI watchdog message on hybrid perf vendor events power10: Adds 24x7 nest metric events for power10 platform perf script python: Fix buffer size to report iregs in perf script perf trace: Fix the perf trace link location perf top: Fix overflow in elf_sec__is_text() perf annotate: Fix 's' on source line when disasm is empty perf probe: Do not show @plt function by default ...

Commit dbbee9d5 ("mm/page_alloc: convert per-cpu list protection to local_lock") folded in a workaround patch for pahole that was unable to deal with zero-sized percpu structures. A superior workaround is achieved with commit a0b8200d ("kbuild: skip per-CPU BTF generation for pahole v1.18-v1.21"). This patch reverts the dummy field and the pahole version check.
