This commits sets the stage for a change of behavior
in a later commit.
When checking FILE_READ_DATA on the COPYCHUNK dest handle,
only check the handle readability and not the extra right
that may have been added due to the FILE_EXECUTE right.
The check for FILE_READ_DATA always seemed strange for the
dest handle, which is not read. It turns out that in Windows,
this check is not done at the SMB layer, but at a lower layer
that processes the IOCTL request - the IOCTL code has bits
that specify what type of access check needs to be done.
Therefore, this lower layer is unaware of the SMB layer's
practice of granting READ access based on the FILE_EXECUTE
right, and it only checks the handle's readability.
This subtle difference has observable behavior - the
COPYCHUNK source handle can have FILE_EXECUTE right instead
of FILE_READ_DATA, but the dest handle cannot.

Note: This has *NO* effect on the lock context code, as on the
wire for all SMB1 locking requests, the pid used as the lock
context is already truncated down to 16-bits - the field is only
16-bits wide.
This allows the cli_XXX() calls to correctly set pidlow AND pidhigh
in SMB1 requests put on the wire by the libcli/smb/smb1*.c code.
Note that currently the smbd server doesn't correctly return
pidhigh yet - a fix (and tests) for that will follow.
As pidhigh is not checked in any client code (mid is used
to differentiate different requests) this has no effect
other than a correctness fix.

Smbd would disable "store dos attributes" on-the-fly if the
attempt to set/get user.DOSATTRIB fails with ENOTSUP or ENOSYS.
The rationale behind it was that the file system does not support
extended attributes, so there's no need to fill up the log with
failure messages.
However, a "wide symlink" could point to a spot that doesn't support
extended attributes. Even with the default banned wide links, we
currenly allow stat'ing those files and follow the symlink, and this
in turn would disable "store dos attributes" for the whole share.
The user.DOSATTRIB attribute also stores file creation time,
so that is also affected.
Another case where this behavior would turn storage of DOS attributes
off is that of the ".." entry at the root of the share, if the parent
folder for the share's root path does not support extended attributes.
On the other hand, the information on the file system and its support
of extended attributes is readily available, so the fix for explosion
of the log should be not to configure "store dos attributes" on
such a share.

If Samba is configured with FALLOC_FL_PUNCH_HOLE support, then allow
sys_fallocate() to propogate the flag to syscall invocation.
Signed-off-by: David Disseldorp <ddiss@samba.org>
Reviewed-by: Jeremy Allison <jra@samba.org>
The Linux fallocate syscall offers a mode parameter which can take the
following flags:
FALLOC_FL_KEEP_SIZE
FALLOC_FL_PUNCH_HOLE (since 2.6.38)
FALLOC_FL_COLLAPSE_RANGE (since 3.15)
FALLOC_FL_ZERO_RANGE (since 3.14)
The flags are not exclusive, e.g. FALLOC_FL_PUNCH_HOLE must be specified
alongside FALLOC_FL_KEEP_SIZE.
Samba currently takes a vfs_fallocate_mode enum parameter for the VFS
fallocate hook, taking either an EXTEND_SIZE or KEEP_SIZE value. This
commit changes the fallocate hook such that it accepts a uint32_t flags
parameter, in preparation for PUNCH_HOLE and ZERO_RANGE support.

What?
This patch gets rid of the central shared memory segment referenced by
"profile_p". Instead, every smbd gets a static profile_area where it collects
profiling data. Once a second, every smbd writes this profiling data into a
record of its own in a "smbprofile.tdb". smbstatus -P does a tdb_traverse on this
database and sums up what it finds.
Why?
At least in my perception sysv IPC has not the best reputation on earth. The
code before this patch uses shmat(). Samba ages ago has developed a good
abstraction of shared memory: It's called tdb.
The main reason why I started this is that I have a request to become
more flexible with profiling data. Samba should be able to collect data
per share or per user, something which is almost impossible to do with
a fixed structure. My idea is to for example install a profile area per
share and every second marshall this into one tdb record indexed by share
name. smbstatus -P would then also collect the data and either aggregate
them or put them into individual per-share statistics. This flexibility
in the data model is not really possible with one fixed structure.
But isn't it slow?
Well, I don't think so. I can't really prove it, but I do believe that on large
boxes atomically incrementing a shared memory value for every SMB does show up
due to NUMA effects. With this patch the hot code path is completely
process-local. Once a second every smbd writes into a central tdb, this of
course does atomic operations. But it's once a second, not on every SMB2 read.
There's two places where I would like to improve things: With the current code
all smbds wake up once a second. With 10,000 potentially idle smbds this will
become noticable. That's why the current only starts the timer when something has
changed.
The second place is the tdb traverse: Right now traverse is blocking in the
sense that when it has to switch hash chains it will block. With mutexes, this
means a syscall. I have a traverse light in mind that works as follows: It
assumes a locked hash chain and then walks the complete chain in one run
without unlocking in between. This way the caller can do nonblocking locks in
the first round and only do blocking locks in a second round. Also, a lot of
syscall overhead will vanish. This way smbstatus -P will have almost zero
impact on normal operations.

In order to have useful profiling counters should never be decremented.

We also use better names and avoid having an array for the flush reasons.
This will simplify further profiling improvements a lot.
