Kernel version 5.17 has increased the size of "struct fuse_init_in" struct.
Previously this struct was 16 bytes and now it has been extended to
64 bytes in size.
Once qemu headers are updated to latest, it will expect to receive 64 byte
size struct (for protocol version major 7 and minor > 6). But if guest is
booting older kernel (older than 5.17), then it still sends older
fuse_init_in of size 16 bytes. And do_init() fails. It is expecting
64 byte struct. And this results in mount of virtiofs failing.
Fix this by parsing 16 bytes only for now. Separate patches will be
posted which will parse rest of the bytes and enable new functionality.
Right now we don't support any of the new functionality, so we don't
lose anything by not parsing bytes beyond 16.

OK, I think we should make this 1/9 and get this in quickly; that way
bisect works.

Yeh so that sizeof() is sizeof the flags, so that's the size of the
sturcture upto and including the flags.

Add some code to parse extended "struct fuse_init_in". And use a local
variable "flag" to represent 64 bit flags. This will make it easier
to add more features without having to worry about two 32bit flags (->flags
and ->flags2) in "fuse_struct_in".

Instead of reading upto sizeof(*arg) should we actually read up to the
size of the last field we know about? That way if fuse_init_in grows
again this wont break?

I think that makes sense. Can probably call it init_size_v7_36, which
represents size of fuse_init till protocol version 7.36 extension.
Will update the patch.

->capable keeps track of what capabilities kernel supports and ->wants keep
track of what capabilities filesytem wants.
Right now these fields are 32bit in size. But now fuse has run out of
bits and capabilities can now have bit number which are higher than 31.
That means 32 bit fields are not suffcient anymore. Increase size to 64
bit so that we can add newer capabilities and still be able to use existing
code to check and set the capabilities.

I think this will be OK in practice (need to check 32 bit); but weren't
you using llx in the last patch?

Probably I should use %llx so that it works fine on 32 bit. Will change
it.

Add capability to enable and parse security context as sent by client
and put into fuse_req. Filesystems now can get security context from
request and set it on files during creation.

Move core file creation bits in a separate function. Soon this is going
to get more complex as file creation need to set security context also.
And there will be multiple modes of file creation in next patch.

This patch adds support to set /proc/thread-self/attr/fscreate before
file creation. It is set to a value as sent by client. This will allow
for atomic creation of security context on files w.r.t file creation.
This is primarily useful when either there is no SELinux enabled on
host or host and guest policies are in sync and don't conflict.

To: qemu-devel, virtio-fs; +Cc: mszeredi, stefanha, dgilbert, vgoyal
If guest and host policies can't work with each other, then guest security
context (selinux label) needs to be set into an xattr. Say remap guest
security.selinux xattr to trusted.virtiofs.security.selinux.
That means setting "fscreate" is not going to help as that's ony useful
for security.selinux xattr on host.
So we need another method which is atomic. Use O_TMPFILE to create new
file, set xattr and then linkat() to proper place.
But this works only for regular files. So dir, symlinks will continue
to be non-atomic.
Also if host filesystem does not support O_TMPFILE, we fallback to
non-atomic behavior.

Provide an option "-o security_label/no_security_label" to enable/disable
security label functionality. By default these are turned off.
If enabled, server will indicate to client that it is capable of handling
one security label during file creation. Typically this is expected to
be a SELinux label. File server will set this label on the file. It will
try to set it atomically wherever possible. But its not possible in
all the cases.
