efivarfs: Ensure VariableName is NUL-terminated

2015-06-28T17:39:26+00:00

[ Upstream commit c57dcb566d3d866a302a1da2e06344bec31d5bcd ]

Some buggy firmware implementations update VariableNameSize on success
such that it does not include the final NUL character which results in
garbage in the efivarfs name entries.  Use kzalloc on the efivar_entry
(as is done in efivars.c) to ensure that the name is always
NUL-terminated.

The buggy firmware is:

efivarfs: 'efivarfs_file_write' function reorganization

2014-03-04T16:16:16+00:00

This reorganization removes useless 'bytes' prior assignment and uses
'memdup_user' instead 'kmalloc' + 'copy_from_user'.

consolidate simple ->d_delete() instances

2013-11-16T03:04:17+00:00

Rename simple_delete_dentry() to always_delete_dentry() and export it.
Export simple_dentry_operations, while we are at it, and get rid of
their duplicates

Don't pass inode to ->d_hash() and ->d_compare()

2013-06-29T08:57:36+00:00

Instances either don't look at it at all (the majority of cases) or
only want it to find the superblock (which can be had as dentry->d_sb).
A few cases that want more are actually safe with dentry->d_inode -
the only precaution needed is the check that it hadn't been replaced with
NULL by rmdir() or by overwriting rename(), which case should be simply
treated as cache miss.

efivarfs: Never return ENOENT from firmware again

2013-05-13T19:12:10+00:00

Previously in 1fa7e69 efi_status_to_err() translated firmware status
EFI_NOT_FOUND to -EIO instead of -ENOENT for efivarfs operations to
avoid confusion. After refactoring in e14ab23, it is also used in other
places where the translation may be unnecessary.

So move the translation to efivarfs specific code. Also return EOF
for reading zero-length files, which is what users would expect.

Pull VFS updates from Al Viro,

Misc cleanups all over the place, mainly wrt /proc interfaces (switch
create_proc_entry to proc_create(), get rid of the deprecated
create_proc_read_entry() in favor of using proc_create_data() and
seq_file etc).

7kloc removed.
