      crypto: caam - defer aead_set_sh_desc in case of zero authsize · 2fdea258
      Horia Geantă authored
      To be able to generate shared descriptors for AEAD, the authentication size
      needs to be known. However, there is no imposed order of calling .setkey,
      .setauthsize callbacks.
      
      Thus, in case authentication size is not known at .setkey time, defer it
      until .setauthsize is called.
      
      The authsize != 0 check was incorrectly removed when converting the driver
      to the new AEAD interface.

      crypto: caam - fix echainiv(authenc) encrypt shared descriptor · 1d2d87e8
      Horia Geantă authored
      There are a few things missed by the conversion to the
      new AEAD interface:
      
      1 - echainiv(authenc) encrypt shared descriptor
      
      The shared descriptor is incorrect: due to the order of operations,
      at some point in time MATH3 register is being overwritten.
      
      2 - buffer used for echainiv(authenc) encrypt shared descriptor
      
      Encrypt and givencrypt shared descriptors (for AEAD ops) are mutually
      exclusive and thus use the same buffer in context state: sh_desc_enc.
      
      However, there's one place missed by s/sh_desc_givenc/sh_desc_enc,
      leading to errors when echainiv(authenc(...)) algorithms are used:
      DECO: desc idx 14: Header Error. Invalid length or parity, or
      certain other problems.
      
      While here, also fix a typo: dma_mapping_error() is checking
      for validity of sh_desc_givenc_dma instead of sh_desc_enc_dma.

      block: rename bio bi_rw to bi_opf · 1eff9d32
      Jens Axboe authored
      Since commit 63a4cc24, bio->bi_rw contains flags in the lower
      portion and the op code in the higher portions. This means that
      old code that relies on manually setting bi_rw is most likely
      going to be broken. Instead of letting that brokeness linger,
      rename the member, to force old and out-of-tree code to break
      at compile time instead of at runtime.
      
      No intended functional changes in this commit.

      block/mm: make bdev_ops->rw_page() take a bool for read/write · c11f0c0b
      Jens Axboe authored
      Commit abf54548 changed it from an 'rw' flags type to the
      newer ops based interface, but now we're effectively leaking
      some bdev internals to the rest of the kernel. Since we only
      care about whether it's a read or a write at that level, just
      pass in a bool 'is_write' parameter instead.
      
      Then we can also move op_is_write() and friends back under
      CONFIG_BLOCK protection.

        in the face of mount namespaces and changeroots, so the F mode opens
        the binary as soon as the emulation is installed and uses the opened
        image to spawn the emulator, meaning it is always available once

      fs: return EPERM on immutable inode · 337684a1
      Eryu Guan authored
      In most cases, EPERM is returned on immutable inode, and there're only a
      few places returning EACCES. I noticed this when running LTP on
      overlayfs, setxattr03 failed due to unexpected EACCES on immutable
      inode.
      
      So converting all EACCES to EPERM on immutable inode.
