      lib: zstd: Don't add -O3 to cflags · 7416cdc9
      Nick Terrell authored
      After the update to zstd-1.4.10 passing -O3 is no longer necessary to
      get good performance from zstd. Using the default optimization level -O2
      is sufficient to get good performance.
      
      I've measured no significant change to compression speed, and a ~1%
      decompression speed loss, which is acceptable.
      
      This fixes the reported parisc -Wframe-larger-than=1536 errors [0]. The
      gcc-8-hppa-linux-gnu compiler performed very poorly with -O3, generating
      stacks that are ~3KB. With -O2 these same functions generate stacks in
      the < 100B, completely fixing the problem. Function size deltas are
      listed below:
      
      ZSTD_compressBlock_fast_extDict_generic: 3800 -> 68
      ZSTD_compressBlock_fast: 2216 -> 40
      ZSTD_compressBlock_fast_dictMatchState: 1848 ->  64
      ZSTD_compressBlock_doubleFast_extDict_generic: 3744 -> 76
      ZSTD_fillDoubleHashTable: 3252 -> 0
      ZSTD_compressBlock_doubleFast: 5856 -> 36
      ZSTD_compressBlock_doubleFast_dictMatchState: 5380 -> 84
      ZSTD_copmressBlock_lazy2: 2420 -> 72
      
      Additionally, this improves the reported code bloat [1]. With gcc-11
      bloat-o-meter shows an 80KB code size improvement:
      
      ```
      > ../scripts/bloat-o-meter vmlinux.old vmlinux
      add/remove: 31/8 grow/shrink: 24/155 up/down: 25734/-107924 (-82190)
      Total: Before=6418562, After=6336372, chg -1.28%
      ```
      
      Compared to before the zstd-1.4.10 update we see a total code size
      regression of 105KB, down from 374KB at v5.16-rc1:
      
      ```
      > ../scripts/bloat-o-meter vmlinux.old vmlinux
      add/remove: 292/62 grow/shrink: 56/88 up/down: 235009/-127487 (107522)

      lib: zstd: Don't inline functions in zstd_opt.c · 1974990c
      Nick Terrell authored
      `zstd_opt.c` contains the match finder for the highest compression
      levels. These levels are already very slow, and are unlikely to be used
      in the kernel. If they are used, they shouldn't be used in latency
      sensitive workloads, so slowing them down shouldn't be a big deal.
      
      This saves 188 KB of the 288 KB regression reported by Geert Uytterhoeven [0].
      I've also opened an issue upstream [1] so that we can properly tackle
      the code size issue in `zstd_opt.c` for all users, and can hopefully
      remove this hack in the next zstd version we import.

      lib: zstd: Fix unused variable warning · ae8d67b2
      Nick Terrell authored
      The variable `litLengthSum` is only used by an `assert()`, so when
      asserts are disabled the compiler doesn't see any usage and warns.
      
      This issue is already fixed upstream by PR #2838 [0]. It was reported
      by the Kernel test robot in [1].
      
      Another approach would be to change zstd's disabled `assert()`
      definition to use the argument in a disabled branch, instead of
      ignoring the argument. I've avoided this approach because there are
      some small changes necessary to get zstd to build, and I would
      want to thoroughly re-test for performance, since that is slightly
      changing the code in every function in zstd. It seems like a
      trivial change, but some functions are pretty sensitive to small
      changes. However, I think it is a valid approach that I would
      like to see upstream take, so I've opened Issue #2868 to attempt
      this upstream.
      
      Lastly, I've chosen not to use __maybe_unused because all code
      in lib/zstd/ must eventually be upstreamed. Upstream zstd can't
      use __maybe_unused because it isn't portable across all compilers.

      Pull setattr idmapping fix from Christian Brauner:
       "This contains a simple fix for setattr. When determining the validity
        of the attributes the ia_{g,u}id fields contain the value that will be
        written to inode->i_{g,u}id. When the {g,u}id attribute of the file
        isn't altered and the caller's fs{g,u}id matches the current {g,u}id
        attribute the attribute change is allowed.
      
        The value in ia_{g,u}id does already account for idmapped mounts and
        will have taken the relevant idmapping into account. So in order to
        verify that the {g,u}id attribute isn't changed we simple need to
        compare the ia_{g,u}id value against the inode's i_{g,u}id value.
      
        This only has any meaning for idmapped mounts as idmapping helpers are
        idempotent without them. And for idmapped mounts this really only has
        a meaning when circular idmappings are used, i.e. mappings where e.g.
        id 1000 is mapped to id 1001 and id 1001 is mapped to id 1000. Such
        ciruclar mappings can e.g. be useful when sharing the same home
        directory between multiple users at the same time.
      
        Before this patch we could end up denying legitimate attribute changes
        and allowing invalid attribute changes when circular mappings are
        used. To even get into this situation the caller must've been
        privileged both to create that mapping and to create that idmapped
        mount.
      
        This hasn't been seen in the wild anywhere but came up when expanding
        the fstest suite during work on a series of hardening patches. All
        idmapped fstests pass without any regressions and we're adding new
        tests to verify the behavior of circular mappings.
      
        The new tests can be found at [1]"

      net: ethernet: dec: tulip: de4x5: fix possible array overflows in type3_infoblock() · 0fa68da7
      Teng Qi authored
      The definition of macro MOTO_SROM_BUG is:
        #define MOTO_SROM_BUG    (lp->active == 8 && (get_unaligned_le32(
        dev->dev_addr) & 0x00ffffff) == 0x3e0008)
      
      and the if statement
        if (MOTO_SROM_BUG) lp->active = 0;
      
      using this macro indicates lp->active could be 8. If lp->active is 8 and
      the second comparison of this macro is false. lp->active will remain 8 in:
        lp->phy[lp->active].gep = (*p ? p : NULL); p += (2 * (*p) + 1);
        lp->phy[lp->active].rst = (*p ? p : NULL); p += (2 * (*p) + 1);
        lp->phy[lp->active].mc  = get_unaligned_le16(p); p += 2;
        lp->phy[lp->active].ana = get_unaligned_le16(p); p += 2;
        lp->phy[lp->active].fdx = get_unaligned_le16(p); p += 2;
        lp->phy[lp->active].ttm = get_unaligned_le16(p); p += 2;
        lp->phy[lp->active].mci = *p;
      
      However, the length of array lp->phy is 8, so array overflows can occur.
      To fix these possible array overflows, we first check lp->active and then
      return -EINVAL if it is greater or equal to ARRAY_SIZE(lp->phy) (i.e. 8).

      As reported by Guillaume in [1]:
      Enabling LPAE always enables CONFIG_ARCH_DMA_ADDR_T_64BIT
      in 32-bit systems, which breaks the bootup proceess when a
      ethernet driver is using page pool with PP_FLAG_DMA_MAP flag.
      As we were hoping we had no active consumers for such system
      when we removed the dma mapping support, and LPAE seems like
      a common feature for 32 bits system, so revert it.

      The if statement:
        if (port >= DSAF_GE_NUM)
              return;
      
      limits the value of port less than DSAF_GE_NUM (i.e., 8).
      However, if the value of port is 6 or 7, an array overflow could occur:
        port_rst_off = dsaf_dev->mac_cb[port]->port_rst_off;
      
      because the length of dsaf_dev->mac_cb is DSAF_MAX_PORT_NUM (i.e., 6).
      
      To fix this possible array overflow, we first check port and if it is
      greater than or equal to DSAF_MAX_PORT_NUM, the function returns.
