Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.By default all files without license information are under the default
license of the kernel, which is GPL version 2.Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if

Zero newly allocated extents in the catalog tree if volume attributes
tell us to. Not doing so we risk getting the "unused node is not
erased" error. See kHFSUnusedNodeFix flag in Apple's source code for
reference.There was a previous commit clearing the node when it is freed: commit
899bed05e9f6 ("hfsplus: fix issue with unzeroed unused b-tree nodes").
But it did not handle newly allocated extents (this patch fixes it).
And it zeroed nodes in all trees unconditionally which is an overkill.This patch adds a condition and also switches to 'tree->node_size' as a
simpler method of getting the length to zero.Signed-off-by: Sergei Antonov

Adds support for HFSX 'HasFolderCount' flag and a corresponding
'folderCount' field in folder records. (For reference see
HFS_FOLDERCOUNT and kHFSHasFolderCountBit/kHFSHasFolderCountMask in
Apple's source code.)Ignoring subfolder count leads to fs errors found by Mac:
...
Checking catalog hierarchy.
HasFolderCount flag needs to be set (id = 105)
(It should be 0x10 instead of 0)
Incorrect folder count in a directory (id = 2)
(It should be 7 instead of 6)
...Steps to reproduce:
Format with "newfs_hfs -s /dev/diskXXX".
Mount in Linux.
Create a new directory in root.
Unmount.
Run "fsck_hfs /dev/diskXXX".The patch handles directory creation, deletion, and rename.

hfs seems prone to bad things when it encounters on disk corruption. Many
values are read from disk, and used as lengths to memcpy, as an example.
This patch fixes up several of these problematic cases.o sanity check the on-disk maximum key lengths on mount
(these are set to a defined value at mkfs time and shouldn't differ)
o check on-disk node keylens against the maximum key length for each tree
o fix hfs_btree_open so that going out via free_tree: doesn't wind
up in hfs_releasepage, which wants to follow the very pointer
we were trying to set up:
HFS_SB(sb)->cat_tree = hfs_btree_open()
.
failure gets to hfs_releasepage and tries to follow HFS_SB(sb)->cat_treeTested with the fsfuzzer; it survives more than it used to.

Extend the set of "__attribute__" shortcut macros, and remove identical
(and now superfluous) definitions from a couple of source files.based on a page at robert love's blog:
http://rlove.org/log/2005102601
extend the set of shortcut macros defined in compiler-gcc.h with the
following:#define __packed __attribute__((packed))
#define __weak __attribute__((weak))
#define __naked __attribute__((naked))
#define __noreturn __attribute__((noreturn))
#define __pure __attribute__((pure))
#define __aligned(x) __attribute__((aligned(x)))
#define __printf(a,b) __attribute__((format(printf,a,b)))Once these are in place, it's up to subsystem maintainers to decide if they
want to take advantage of them. there is already a strong precedent for
using shortcuts like this in the source tree.The ones that might give people pause are "__aligned" and "__printf", but
shortcuts for both of those are already in use, and in some ways very
confusingly. note the two very different definitions for a macro named
"ALIGNED":drivers/net/sgiseeq.c:#define ALIGNED(x) ((((unsigned long)(x)) + 0xf) & ~(0xf))
drivers/scsi/ultrastor.c:#define ALIGNED(x) __attribute__((aligned(x)))also:
include/acpi/platform/acgcc.h:
#define ACPI_PRINTF_LIKE(c) __attribute__ ((__format__ (__printf__, c, c+1)))Given the precedent, then, it seems logical to at least standardize on a
consistent set of these macros.Signed-off-by: Robert P. J. Day

Access to a journaled HFS+ volume is not officially supported under Linux, so
mount such a volume read-only, but users can override this behaviour using the
"force" mount option.The minimum requirement to relax this check is to at least check that the
journal is empty and so nothing needs to be replayed to make sure the volume
is consistent.Signed-off-by: Roman Zippel

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
