61d9c0d92e smbd: add options "fs:[logical|aligned|performance|effective aligned] bytes per sector"
In order to support certain Windows applications that make use of copy reflink,
we need some way to allow configuring these values. According to testing, the
application somehow uses the value of phys_bytes_per_sector_atomic for some check
when requesting server-side reflink copies, eg for ZFS the following is needed

 block size = 131072
 fs:aligned bytes per sector = 131072

For some reason "block size" must also be set to the value of fs:aligned bytes
per sector, but fs:logical bytes per sector, which according to the spec should
match "block size", must stay at the default of 512, otherwise the application
does not work.

As the whole client behaviour could not be fully understood, I'm proposing to
introduce these options as undocumented parametric options, so we can at least
start testing with them.

deeca8ff17 smbd: consolidate fs capabilities code in vfswrap_fs_capabilities()
This ensures the values we return via SMB_FS_ATTRIBUTE_INFORMATION is the same
we use internally via conn->fs_capabilities.

This deliberately preserves existing behaviour as much as possible and leaves
possible improvements as a future excercize. Particularily FILE_VOLUME_QUOTAS is
already set insided SMB_VFS_STATVFS() depending on backend filesystem flags
which is probably the correct way to do it instead of just setting the
capability when Samba was built with quota support.

17becb5f52 smbd: Respect per-user hide and veto files with parametric options
For my taste this is a nicer configuration syntax than

/../username1/file1/../username2/file2/

Is this too expensive? I don't think so. The scanning only happens an
tcon time, and it only walks the parametric options. If this turns out
to be a performance problem, we should think about smarter data
structures for parametric options instead of just a linked list of
string triples for everything.

fcd595a464 lib: Factor out append_namearray from set_namearray
We'll have to add to an existing namearray soon.

This turns one talloc_array() into a set of reallocs. This is slower,
but set_namearray is only used for smb.conf entries where we don't
expect hundreds or more entries to add. I've done this to avoid array
length calculations, but if it turns out to be too slow we can get
smarter again.

Upon calling to libcephfs this new code crates and destroys on-the-fly
a Ceph UserPerm instance based on the uig, gid and groups from
'handle->conn->session_info->unix_token'. This logic ensures that the
correct caller-credentials are passed-on to cephfs (instead of those

ef0068cd2c vfs_ceph: Disable the module on unsupported Ceph versions
For the last major release(v4.20) we had a warning issued(fe16ae1fe8)
to inform about the plan to disable building vfs_ceph in the absence of
certain required APIs. This is now due to make the changes and further
disable building the module if minimum required libcephfs APIs are not
present. As we speak this requirement includes ceph_select_filesystem()
and *at() variants of libcephfs APIs. These were around since v17(even
earlier for ceph_select_filesystem) which is the lowest non-EOL version
of Ceph available[1] at the moment.

90c9d0d98d s3:ntlm_auth: make logs more consistent with length check
Run ntlm_auth with options --lm-response/--nt-response/--challenge, and pass
wrong length to these options, got error prompted logs about 'only got xxx
bytes', which are not consistent with length check. This patch revise logs
for length check to make it more consistent.

For example --lm-response requires exact 24 hex, let us input three kinds
of length 23 24 25, prompted logs said 'only got 25 bytes' seems confusing.

script:
for length in 23 24 25; \
do \
    ntlm_auth --username=${un} --password=${pw} \
    --lm-response="`openssl rand -hex ${length}`"; \
done;

output:
hex decode of 04db772593f5e6023d0ab4bc67a942c9179963477eb49d failed! (only got 23 bytes)

hex decode of 1e57749feb46bedcf969af6cbbe10e21d0232e35c27eb07294 failed! (only got 25 bytes)

After patch it shows 'got 25 bytes, expected 24' seems more consistent:

hex decode of e13e70c9cf2ac1e20015657c4bec53435b1b948febb63f failed! (got 23 bytes, expected 24)

0ebabaedbc smbd: Fix cached dos attributes
The callers of fset_dos_mode must set the cached attributes
themselves, which I did not see. I tried, but I did not find a clean
way to fix this behind SMB_VFS_FSET_DOS_ATTRIBUTES, with a smb_fname
and smb_fname->fsp->fsp_name we might have two copies of the cached
dos attributes around and if we only update fsp->fsp_name, we might
miss the outer one.

Not doing a test, this is really fresh code, and in the future we must
reorganize setting and caching dos attributes anyway.
