      fscrypt: don't allow v1 policies with casefolding · 6e1918cf
      Daniel Rosenberg authored
      Casefolded encrypted directories will use a new dirhash method that
      requires a secret key.  If the directory uses a v2 encryption policy,
      it's easy to derive this key from the master key using HKDF.  However,
      v1 encryption policies don't provide a way to derive additional keys.
      
      Therefore, don't allow casefolding on directories that use a v1 policy.
      Specifically, make it so that trying to enable casefolding on a
      directory that has a v1 policy fails, trying to set a v1 policy on a
      casefolded directory fails, and trying to open a casefolded directory
      that has a v1 policy (if one somehow exists on-disk) fails.

      fscrypt: add "fscrypt_" prefix to fname_encrypt() · 1b3b827e
      Eric Biggers authored
      fname_encrypt() is a global function, due to being used in both fname.c
      and hooks.c.  So it should be prefixed with "fscrypt_", like all the
      other global functions in fs/crypto/.

      fscrypt: don't print name of busy file when removing key · 13a10da9
      Eric Biggers authored
      When an encryption key can't be fully removed due to file(s) protected
      by it still being in-use, we shouldn't really print the path to one of
      these files to the kernel log, since parts of this path are likely to be
      encrypted on-disk, and (depending on how the system is set up) the
      confidentiality of this path might be lost by printing it to the log.
      
      This is a trade-off: a single file path often doesn't matter at all,
      especially if it's a directory; the kernel log might still be protected
      in some way; and I had originally hoped that any "inode(s) still busy"
      bugs (which are security weaknesses in their own right) would be quickly
      fixed and that to do so it would be super helpful to always know the
      file path and not have to run 'find dir -inum $inum' after the fact.
      
      But in practice, these bugs can be hard to fix (e.g. due to asynchronous
      process killing that is difficult to eliminate, for performance
      reasons), and also not tied to specific files, so knowing a file path
      doesn't necessarily help.
      
      So to be safe, for now let's just show the inode number, not the path.
      If someone really wants to know a path they can use 'find -inum'.

       - And then the series that I hinted at from last week, which removes
         the sqe from the io_kiocb and keeps all sqe handling on the prep
         side. This guarantees that an opcode can't do the wrong thing and
         read the sqe more than once. This is unchanged from last week, no
         issues have been observed with this in testing. Hence I really think
         we should fold this into 5.5.

      ata: ahci_brcm: Add missing clock management during recovery · bf0e5013
      Florian Fainelli authored
      The downstream implementation of ahci_brcm.c did contain clock
      management recovery, but until recently, did that outside of the
      libahci_platform helpers and this was unintentionally stripped out while
      forward porting the patch upstream.
      
      Add the missing clock management during recovery and sleep for 10
      milliseconds per the design team recommendations to ensure the SATA PHY
      controller and AFE have been fully quiesced.

      Set AHCI_HFLAG_DELAY_ENGINE for the BCM7425 AHCI controller thus making
      it conforming to the 'strict' AHCI implementation which this controller
      is based on.
      
      This solves long link establishment with specific hard drives (e.g.:
      Seagate ST1000VM002-9ZL1 SC12) that would otherwise have to complete the
      error recovery handling before finally establishing a succesful SATA
      link at the desired speed.
      
      We re-order the hpriv->flags assignment to also remove the NONCQ quirk
      since we can set the flag directly.
