The Linux NFS server does not accept a setting of file size to 0 for
sockets and FIFOs so there is code to strip that for those cases. I also
spotted that the file modification times were not being applied to a
created file so there is now just one rpc to set all file attributes using
xdr_encode_create_state(). This sets the times to be server time which is
appropriate for a new file (even though it was created in the previous RPC
call). The previous code was supplying the 'gid' based on that returned by
the 'stat' but I don't think that can be relied on since the V3 protocol
states that CREATE3 using EXCLUSIVE cannot guarantee any file attributes
until after the SETATTR3.

Better use the stdint.
Also export them, they will be useful generally.
|
|
Shifting signed 0xffffffff 32 bit left is undefined behavior. Cast to
unsigned to make it defined behavior.
|
|
Now that the RPCs have const, this forces us cleaning our const-meant
functions.
