s3/vfs: rename SMB_VFS_STRICT_LOCK to SMB_VFS_STRICT_LOCK_CHECK

2017-07-24T20:00:37+00:00

As per MS-SMB2 and MS-FSA and our SMB_VFS_STRICT_LOCK implementation,
we're merely testing for locks, not setting any.

s3/vfs: remove SMB_VFS_STRICT_UNLOCK

2017-07-24T20:00:37+00:00

It's just a noop, so let's remove it. SMB_VFS_STRICT_LOCK doesn't set
logs, it just checks for the presence of incompatible locks.

s3: smbd: Fix open_files.idl to correctly ignore share_mode_lease *lease in share_mode_entry.

2017-05-18T01:01:40+00:00

This is currently marked 'skip', which means it isn't stored in the
db, but printed out in ndr dump. However, this pointer can be invalid
if the lease_idx is set to 0xFFFFFFFF (invalid).

This is fixed up inside parse_share_modes(), but not until after
ndr_pull_share_mode_data() is called. If lease_idx == 0xFFFFFFFF
then ndr_print_share_mode_lease() prints an invalid value and
crashes.

Add some helper functions that will be used to update a bunch of checks
for exclusive oplocks to the lease area.

s3/locking: add fetch_share_mode_send/recv

2017-04-18T20:54:16+00:00

The boolean out parameter "queued" tells the caller whether the
async request is blocked in a full send queue:

false := request is dispatched
true  := send queue is full, request waiting to be dispatched

This is useful in a clustered Samba environment where the async dbwrap
request is sent over a socket to the local ctdbd.

If the send queue is full and the caller was issuing multiple async
dbwrap requests in a loop, the caller knows it's probably time to stop
sending requests for now and try again later.

This will be used in subsequent commits in
smbd_smb2_query_directory_send() when implementing async write time
updates. Directories may contain umpteen files so we send many requests
to ctdb without going through tevent and reading the responses which
has the potential to deadlock.
