  • 897fba117   remove directory incorrectly tries to set delete on close on non-empty directories ... Browse Code »

    Wrong return code was being returned on SMB3 rmdir of
    non-empty directory.

    For SMB3 (unlike for cifs), we attempt to delete a directory by
    set of delete on close flag on the open. Windows clients set
    this flag via a set info (SET_FILE_DISPOSITION to set this flag)
    which properly checks if the directory is empty.

    With this patch on smb3 mounts we correctly return
    "DIRECTORY NOT EMPTY"
    on attempts to remove a non-empty directory.

  • 2365c4eaf   CIFS: Fix too big maxBuf size for SMB3 mounts ... Browse Code »

    SMB3 servers can respond with MaxTransactSize of more than 4M
    that can cause a memory allocation error returned from kmalloc
    in a lock codepath. Also the client doesn't support multicredit
    requests now and allows buffer sizes of 65536 bytes only. Set
    MaxTransactSize to this maximum supported value.

  • 429b46f4f   [CIFS] SMB3 Signing enablement ... Browse Code »

    SMB3 uses a much faster method of signing (which is also better in other ways),
    AES-CMAC. With the kernel now supporting AES-CMAC since last release, we
    are overdue to allow SMB3 signing (today only CIFS and SMB2 and SMB2.1,
    but not SMB3 and SMB3.1 can sign) - and we need this also for checking
    secure negotation and also per-share encryption (two other new SMB3 features
    which we need to implement).

    This patch needs some work in a few areas - for example we need to
    move signing for SMB2/SMB3 from per-socket to per-user (we may be able to
    use the "nosharesock" mount option in the interim for the multiuser case),
    and Shirish found a bug in the earlier authentication overhaul
    (setting signing flags properly) - but those can be done in followon
    patches.
