Yes, the formatting is not according to README.Coding, but that's a
patch for another day.
Also, this is no functional change: All callers so far either set

This wrongly used "frame" instead of "fname", which can never have
worked. A first attempt to fix in 51551e0d53 caused a few followup
patches in an attempt to clean up the test failures 51551e0d53
introduced. They were reverted after a few discussions. So rather than
changing behaviour, just remove the code that introduced the valgrind
error again.

This keeps the original SMB_STRUCT_STAT coming from posix as part of
struct file_info. It is a slight waste of space, as the timestamps are
kept twice, but having a full SMB_STRUCT_STAT with the nlink!=0
validity check makes thinking about which mode/size/etc is the correct
one a no-brainer. We can save space later by referencing only one set
of time stamps for example.
This for the time fixes readdirplus2, but for the wrong reason: We don't yet
create files the "proper" way using posix create.

This fixes doing strlen() on talloc_tos(), about which valgrind is pretty
unhappy. Without this patch we survive the tests because we have fallbacks to
the non-posix flavors of stat(). With this patch in place cli_posix_stat()
becomes functional in this code path. This creates conflicts with the readdir
libsmbclient tests, which need fixing separately.

This is a deviation from the Posix readlink function that from my
point of view makes this function easier to use. In Posix, probably
the assumption is that readlink is cheap, so someone under memory
constraints could just start with a small buffer and incrementally
increase the buffer size. For us, it's a network round-trip, and we
have the luxury of [mt]alloc, which the syscall kernel interface does
not have.

smbd does posix_mkdir if the wire flags are exactly
if (wire_open_mode == (SMB_O_CREAT|SMB_O_DIRECTORY))
open_flags_to_wire however adds a SMB_O_RDONLY, so that we enter the
normal open routine which happens to create a directory as well. The
main difference is that posix_mkdir does *NOT* return an open
handle. As we did not enter this code path due to the SMB_O_RDONLY we
leak a SMB1 fd per cli_posix_mkdir call.
Pretty hard to test automatically, this would be an interaction with
smbstatus.

If PyArg_ParseTupleAndKeywords() is given, say, an "H" format (meaning
unsigned short int) but the referenced variable is a plain unsigned
int, the top 16 bits of the variable will be left undefined. In that
case we should use an "I" format (and/or initialize the variable).
In many cases the change is fairly innocuous, such as when "i" and "I"
are mixed (for signed and unsigned ints respectively), but the
resulting write is the same size and probably gives the same result in
practice.

Add FILE_READ_ATTRIBUTES when opening the file handle, as we need to

cli_smb2_list() appears to be a slightly unique SMB operation in that it
specifies the max transaction size for the response buffer size. The
Python bindings highlighted a problem where if cli_smb2_list() were one
of the first operations performed on the SMBv2 connection, it would fail
due to insufficient credits. Because the response buffer size is
(potentially) so much larger, it requires more credits (128) compared
with other SMB operations.
When talking to a samba DC, the connection credits seem to start off at
1, then increase by 32 for every SMB reply we receive back from the
server. After cli_full_connection(), the connection has 65 credits. The
cli_smb2_create_fnum() in cli_smb2_list() adds another 32 credits, but
this is still less than the 128 that smb2cli_query_directory() requires.
This problem doesn't happen for smbclient because the cli_cm_open() API
it uses ends up sending more messages, and so the connection has more
credits.
This patch changes cli_smb2_list(), so it requests a smaller response
buffer size if it doesn't have enough credits available for the max
transaction size. smb2cli_query_directory() is already in a loop, so it
can span multiple SMB messages if for some reason the transaction size
isn't big enough for the listings.

This basically re-uses the underlying functionality of existing APIs in
order to support a .deltree() API, i.e.
- we use the .list() functionality (i.e. do_listing()) to traverse every
item in the given directory.
- we then use either .unlink() (i.e. unlink_file()) or .rmdir() (i.e.
remove_dir()) to delete the individual item.
- sub-directories are handled recursively, by repeating the process.
Note that the .deltree() API is currently only really used for testing
(and deleting GPO files). So the recursion is never going to be
excessive.
