devtmpfs: get rid of bogus mkdir in create_path() · 5da4e689

由 Al Viro 提交于 6月 27, 2011

We do _NOT_ want to mkdir the path itself - we are preparing to
mknod it, after all.  Normally it'll fail with -ENOENT and
just do nothing, but if somebody has created the parent in
the meanwhile, we'll get buggered...

be used with LOOKUP_PARENT).  Games with credentials are also gone.

don't pass nameidata to vfs_create() from ecryptfs_create() · bf6c7f6c

由 Al Viro 提交于 6月 25, 2011

Instead of playing with removal of LOOKUP_OPEN, mangling (and
restoring) nd->path, just pass NULL to vfs_create().  The whole
point of what's being done there is to suppress any attempts
to open file by underlying fs, which is what nd == NULL indicates.

fix mknod() on nfs4 (hopefully) · f7c85868

由 Al Viro 提交于 6月 22, 2011

a) check the right flags in ->create() (LOOKUP_OPEN, not LOOKUP_CREATE)
b) default (!LOOKUP_OPEN) open_flags is O_CREAT|O_EXCL|FMODE_READ, not 0
c) lookup_instantiate_filp() should be done only with LOOKUP_OPEN;
otherwise we need to issue CLOSE, lest we leak stateid on server.
