Subject: nfsd: apply umask on fs without ACL support
|
||||
Origin: http://git.linux-nfs.org/?p=bfields/linux.git;a=commit;h=22cf8419f1319ff87ec759d0ebdff4cbafaee832
|
||||
Bug-Debian: https://bugs.debian.org/962254
|
||||
|
||||
The server is failing to apply the umask when creating new objects on
|
||||
filesystems without ACL support.
|
||||
|
||||
To reproduce this, you need to use NFSv4.2 and a client and server
|
||||
recent enough to support umask, and you need to export a filesystem that
|
||||
lacks ACL support (for example, ext4 with the "noacl" mount option).
|
||||
|
||||
Filesystems with ACL support are expected to take care of the umask
|
||||
themselves (usually by calling posix_acl_create).
|
||||
|
||||
For filesystems without ACL support, this is up to the caller of
|
||||
vfs_create(), vfs_mknod(), or vfs_mkdir().
