addbf4cc3b s3: smbd: Allow dfs_redirect() to return a TWRP token it got from a parsed pathname.
This one is subtle. If an SMB1 request has both a DFS path and a @GMT token,
the unix_convert() inside the DFS path processing will remove the @GMT
token, not allowing the subsequent unix_convert() inside filename_convert()
to see it. By returning it from dfs_redirect() we can ensure it's correctly
added to the smb_filename returned from filename_convert().

good way to split this up into more manageable pieces without
sacrificing bisectability even more. Probably I could cut out a few
small ones, but a major architechtural switch like this will always be

We missed these values which follow from MS-FSCC 2.3.80 “FSCTL_OFFLOAD_READ
Reply”:

  Flags (4 bytes):

    A 32-bit unsigned integer that indicates which flags were returned for this
    operation. Possible values for the flags follow. All unused bits are reserved
    for future use, SHOULD be set to 0, and MUST be ignored.

    OFFLOAD_READ_FLAG_ALL_ZERO_BEYOND_CURRENT_RANGE (0x00000001)
    => The data beyond the current range is logically equivalent to zero.

  TransferLength (8 bytes):

    A 64-bit unsigned integer that contains the amount, in bytes, of data that the
    Token logically represents. This value indicates a contiguous region of the
    file from the beginning of the requested offset in the FileOffset field in the
    FSCTL_OFFLOAD_READ_INPUT data element (section 2.3.79). This value can be
    smaller than the CopyLength field specified in the FSCTL_OFFLOAD_READ_INPUT
    data element, which indicates that less data was logically
    represented (logically read) with the Token than was requested. The value of
    this field MUST be greater than 0x0000000000000000 and MUST be aligned to a
    logical sector boundary on the volume.

As we currently only implement COPY_CHUNK over the OFFLOAD VFS interface, the
VFS COPY_CHUNK backend in vfs_default just sets both values to 0 and they are
unused in the SMB frontend.

2c18a98253 Don't use sysconf(_SC_NGROUPS_MAX) on macOS for getgroups()
On MacOS sysconf(_SC_NGROUPS_MAX) always returns 16. However, this is not
the value used by getgroups(2). MacOS uses nested groups but getgroups(2)
will return the flattened list which can easily exceed 16 groups. In my
testing getgroups() already returns 16 groups on a freshly installed
system. And on a 10.14 system the root user is in more than 16 groups by
default which makes it impossible to run smbd without this change.
Setting _DARWIN_UNLIMITED_GETGROUPS allows getgroups() to return more than
16 groups. This also changes set_unix_security_ctx() to only set up to
16 groups since that is the limit for initgroups() according to the manpage.

Complex code paths inside open_internal_dirfsp() can return an

2acad27686 s3: smbd: Don't leak meta-data about the containing directory of the share root.
This is a subtle one. In smbd_dirptr_get_entry() we now
open a pathref fsp on all entries - including "..".

If we're at the root of the share we don't want
a handle to the directory above it, so silently
close the smb_fname->fsp for ".." names to prevent
it from being used to return meta-data to the client
(more than we already have done historically by
calling pathname functions on "..").

The marshalling returned entries and async DOS
code copes with smb_fname->fsp == NULL perfectly
well.

Only in master, but will need fixing for 4.15.rc1
or 2.
