  eCryptfs: Print mount_auth_tok_only param in ecryptfs_show_options
  ecryptfs: added ecryptfs_mount_auth_tok_only mount parameter
  ecryptfs: checking return code of ecryptfs_find_auth_tok_for_sig()
  ecryptfs: release keys loaded in ecryptfs_keyring_auth_tok_for_sig()
  eCryptfs: Clear LOOKUP_OPEN flag when creating lower file
  ecryptfs: call vfs_setxattr() in ecryptfs_setxattr()

ecryptfs: added ecryptfs_mount_auth_tok_only mount parameter

2010-10-29T15:31:36+00:00

This patch adds a new mount parameter 'ecryptfs_mount_auth_tok_only' to
force ecryptfs to use only authentication tokens which signature has
been specified at mount time with parameters 'ecryptfs_sig' and
'ecryptfs_fnek_sig'. In this way, after disabling the passthrough and
the encrypted view modes, it's possible to make available to users only
files encrypted with the specified authentication token.

eCryptfs: Strip metadata in xattr flag in encrypted view

2010-03-23T17:31:35+00:00

The ecryptfs_encrypted_view mount option provides a unified way of
viewing encrypted eCryptfs files.  If the metadata is stored in a xattr,
the metadata is moved to the file header when the file is read inside
the eCryptfs mount.  Because of this, we should strip the
ECRYPTFS_METADATA_IN_XATTR flag from the header's flag section.  This
allows eCryptfs to treat the file as an eCryptfs file with a header
at the front.

eCryptfs: Rename ecryptfs_crypt_stat.num_header_bytes_at_front

2010-03-23T17:30:41+00:00

This patch renames the num_header_bytes_at_front variable to
metadata_size since it now contains the max size of the metadata.

eCryptfs: Fix metadata in xattr feature regression

2010-03-23T17:29:49+00:00

Fixes regression in 8faece5f906725c10e7a1f6caf84452abadbdc7b

When using the ecryptfs_xattr_metadata mount option, eCryptfs stores the
metadata (normally stored at the front of the file) in the user.ecryptfs
xattr.  This causes ecryptfs_crypt_stat.num_header_bytes_at_front to be
0, since there is no header data at the front of the file.  This results
in too much memory being requested and ENOMEM being returned from
ecryptfs_write_metadata().

This patch fixes the problem by using the num_header_bytes_at_front
variable for specifying the max size of the metadata, despite whether it
is stored in the header or xattr.
