Revert "fs: fat: assign rootdir sector when accessing root directory"

2019-01-11T15:15:42Z

This particular commit is causing a regression on stih410-b2260 and other platforms when reading from FAT16. Noting that I had rebased the original fix from Thomas onto then-current master, there is also question from Akashi-san if the change is still needed after other FAT fixes that have gone in. This reverts commit a68b0e11ea774492713a65d9fd5bb525fcaefff3. Reported-by: Patrice Chotard Cc: AKASHI Takahiro Cc: Thomas RIENOESSL Signed-off-by: Tom Rini

fs: fix FAT name extraction

2018-12-07T04:26:31Z

The long name apparently can be accumulated using multiple 13-byte slots. Unfortunately we never checked how many we can actually fit in the buffer we are reading to. Signed-off-by: Patrick Wildt

fs: check FAT cluster size

2018-12-07T04:26:31Z

The cluster size specifies how many sectors make up a cluster. A cluster size of zero makes no sense, as it would mean that the cluster is made up of no sectors. This will later lead into a division by zero in sect_to_clust(), so better take care of that early. The MAX_CLUSTSIZE define can reduced using a define to make some room in low-memory system. Unfortunately if the code reads a filesystem with a bigger cluster size it will overflow the buffer. Signed-off-by: Patrick Wildt

This fixes problems accessing drives formated under Windows as FAT16. Signed-off-by: Thomas RIENOESSL [trini: Rebase on top of f528c140c801] Signed-off-by: Tom Rini

fs: fat: Fix warning in normalize_longname()

2018-10-16T14:44:12Z

As observed with clang: fs/fat/fat_write.c:1024:13: warning: comparison of constant 128 with expression of type 'char' is always false [-Wtautological-constant-out-of-range-compare] if ((0x80 <= c) && (c <= 0xff)) ~~~~ ^ ~ fs/fat/fat_write.c:1024:25: warning: comparison of constant 255 with expression of type 'char' is always true [-Wtautological-constant-out-of-range-compare] if ((0x80 <= c) && (c <= 0xff)) ~ ^ ~~~~ Fixes: 25bb9dab14f4 ("fs: fat: check and normalize file name") Signed-off-by: Tom Rini Signed-off-by: Alexander Graf

fs: fat: fix set_cluster()

2018-10-06T18:09:41Z

Avoid CoverityScan warning SIGN_EXTENSION by changing the type of parameter size of set_cluster(). Avoid leaking stack content when writing an incomplete last sector. Reported-by: Coverity (CID: 184096) Signed-off-by: Heinrich Schuchardt

fs: fat: memory leak in fat_unlink()

2018-10-06T18:09:41Z

Do not leak filename_copy in case of error. Catch out of memory when calling strdup. Reported-by: Coverity (CID: 184086) Signed-off-by: Heinrich Schuchardt

fs: fat: unaligned buffers are not an error

2018-09-23T19:55:30Z

The FAT driver supports unaligned reads and writes and EFI applications will make use of these. So a misaligned buffer is only worth a debug message. Signed-off-by: Heinrich Schuchardt Signed-off-by: Alexander Graf

fs: fat: support unlink

2018-09-23T19:55:30Z

In this patch, unlink support is added to FAT file system. A directory can be deleted only if it is empty. In this implementation, only a directory entry for a short file name will be removed. So entries for a long file name can and should be reclaimed with fsck. Signed-off-by: AKASHI Takahiro Signed-off-by: Alexander Graf

fs: fat: support mkdir

2018-09-23T19:55:30Z

In this patch, mkdir support is added to FAT file system. A newly created directory contains only "." and ".." entries. Signed-off-by: AKASHI Takahiro Signed-off-by: Alexander Graf
