9d8aeed33d libsmb: Avoid undefined behaviour when parsing whoami state
If num_gids is such that the gids array would overflow the rdata buffer,
'p + 8' could produce a result pointing outside the buffer, and thus
result in undefined behaviour. To avoid this, we check num_gids against
the size of the buffer beforehand.

2b487890d9 Revert "libsmb: Use sid_parse()"
This reverts commit afd5d34f5e.

This code originally used ndr_pull_struct_blob() to pull one SID from a
buffer potentially containing multiple SIDs. When this was changed to
use sid_parse(), it was now attempting to parse the whole buffer as a
single SID with ndr_pull_struct_blob_all(), which would cause it to fail
if more than one SID was present.

2867950721 s3: lib: Fix the solaris build. Commit 8d0ea8bafa added SMB_ACL_TYPE_T type to solarisacl_sys_acl_set_fd() in the .c file, but not the .h.
The fact no one noticed means currently no one is
building master on Solaris/Illumos/OmniOS.

52744d35a3 nmbd: Reduce the wait interface loop sleep time
Under some circumstances the network-online.target can be reached
without an IPv4 address, for example when using systemd-networkd and
having systemd-networkd-wait-online.service disabled. This will trigger
a five seconds sleep which seems a bit excessive. It is specially
critical when winbind.service is enabled as it won't be started until
nmbd.service is running, delaying the systemd-logind.service five seconds.

Reduce the sleep time from 5 seconds to 250ms to exit the loop as soon
as possible.

33f45491f8 s3: smbd: Remove a STAT/LSTAT call on the parent pathname in a hot code path.

Add support for streams that are larger than 64 KiB in size. Upper
and lower bound are controlled by the parameters smbd max_xattr_size.
Testing against ReFS on Windows (where ADS size is limited in size
shows the server responding with STATUS_FILESYSTEM_LIMITATION.
Do the same in samba for this case.

Currently, large xattrs are supported in FreeBSD.

9b2c17e57a s3:winbindd: Simplfy sequence number caching
The sequence number is used to detect if the cache is still valid. It
expires when the `winbind cache time` is over. After that time we want
to fetch new information from a DC to make sure we are up to date.

If a DC goes down and we recreate the connection, we want to expire the
caches sooner. So we reset the sequence number and the next call should
refill the caches.

Using the current time as the sequence number is more reliable, as the
sequence number of two DCs could in theory be equal. All we have to do
is to make sure we reset it after we reconnect to a DC.

Previously the sequence number check was based on the AD database change
sequence number. Now this is based on a current time value which gets
reset after a successful (re)connect.
