fs: do_load: pass device path for efi payload

2019-06-20T22:26:20+00:00

fatload command can be used to load the EFI payload since EFI system
partition is always a FAT partition. Call into EFI code from do_load()
to set the device path from which the last binary was loaded. An EFI
application like grub2 can’t find its configuration file without the
device path set.

Since device path is now set in do_load() there is no need to set it
in do_load_wrapper() for the load command.

fs: fat: allocate a new cluster for root directory of fat32

2019-05-28T22:55:09+00:00

Contrary to fat12/16, fat32 can have root directory at any location
and its size can be expanded.
Without this patch, root directory won't grow properly and so we will
eventually fail to add files under root directory. Please note that this
can happen even if you delete many files as deleted directory entries
are not reclaimed but just marked as "deleted" under the current
implementation.

fs: fat: flush a directory cluster properly

2019-05-28T22:55:08+00:00

When a long name directory entry is created, multiple directory entries
may be occupied across a directory cluster boundary. Since only one
directory cluster is cached in a directory iterator, a first cluster must
be written back to device before switching over a second cluster.

Without this patch, some added files may be lost even if you don't see
any failures on write operation.

fs: fat: write to non-cluster-aligned root directory

2019-05-28T22:55:08+00:00

With the commit below, fat now correctly handles a file read under
a non-cluster-aligned root directory of fat12/16.
Write operation should be fixed in the same manner.

fs: fat: Fix possible double free of fatbuf

2019-05-28T17:57:52+00:00

fat_itr_root() allocates fatbuf so we free it on the exit path, if
the function fails we should not free it, check the return value
and skip freeing if the function fails.

fs: btrfs: fix btrfs methods return values on failure

2019-05-03T11:30:31+00:00

The btrfs implementation methods .ls(), .size() and .read() returns 1 on
failure, but the command handlers expect values <0 on failure.

For example if given a nonexistent path, the load command currently
returns success, and hush scripting does not work.

Fix this by setting return values of these methods to -1 instead of 1 on
failure.

Revert "fs: btrfs: fix false negatives in ROOT_ITEM search"

2019-04-27T15:35:44+00:00

Per Pierre this change shouldn't have been applied as it was superseded
by "fs: btrfs: fix btrfs_search_tree invalid results" which is also
applied now as 1627e5e5985d.

This reverts commit 633967f9818cb6a0e87ffa8cba33148a5bcc6edb.
