The idea is simple. We need to get the siginfo for each signal on
checkpointing dump, and then return it back on restore.
The first problem is that the kernel doesn't report complete siginfos to
userspace. In a signal handler the kernel strips SI_CODE from siginfo.
When a siginfo is received from signalfd, it has a different format with
fixed sizes of fields. The interface of signalfd was extended. If a
signalfd is created with the flag SFD_RAW, it returns siginfo in a raw
format.
rt_sigqueueinfo looks suitable for restoring signals, but it can't send
siginfo with a positive si_code, because these codes are reserved for
the kernel. In the real world each person has right to do anything with
himself, so I think a process should able to send any siginfo to itself.
This patch:
The kernel prevents sending of siginfo with positive si_code, because
these codes are reserved for kernel. I think we can allow a task to
send such a siginfo to itself. This operation should not be dangerous.
This functionality is required for restoring signals in
checkpoint/restart.

There is no documented methods to mark FAT as dirty. Unofficially MS
started to use reserved Byte in boot sector for this purpose, at least
since Win 2000. With Win 7 user is warned if fs is dirty and asked to
clean it.
Different versions of Win, handle it in different ways, but always have
same meaning:
- Win 2000 and XP, set it on write operations and
remove it after operation was finnished
- Win 7, set dirty flag on first write and remove it on umount.
We will do it as follows:
- set dirty flag on mount. If fs was initially dirty, warn user,
remember it and do not do any changes to boot sector.
- clean it on umount. If fs was initially dirty, leave it dirty.
- do not do any thing if fs mounted read-only.
- TODO: leave fs dirty if we found some error after mount.

The fsck_hfs (under MacOS X) complains about unzeroed unused b-tree nodes
after deletion of folders' tree under Linux.
SYMPTOMS:
Running Disk Utiltiy's "Verify Disk" on "test" gives the following:
Verifying volume “Test”
Checking file systemChecking Journaled HFS Plus volume.
Checking extents overflow file.
Checking catalog file.
Unused node is not erased (node = 3111)
Checking multi-linked files.
Checking catalog hierarchy.
Checking extended attributes file.
Checking volume bitmap.
Checking volume information.
The volume Test was found corrupt and needs to be repaired.
Error: This disk needs to be repaired. Click Repair Disk.
REPRODUCING PATH:
1. Prepare HFS+ (non-case sensitive) partition (for example, 5GB)
under MacOS X.
2. Copy linux kernel source tree (for example, 3.7-rc6 version) on
this partition under MacOS X.
3. Then switch to Linux and mount this prepared partition.
4. Execute `sudo rm -r` under prepared directory with linux kernel
source tree.
5. Unmount and boot back into OS X.
6. Open up Disk Utility and verify partition.
REPRODUCIBILITY: 100%
FIX:
It is added code of node clearing in hfs_bnode_put() method for the case
when node has flag HFS_BNODE_DELETED.

hfsplus: reworked support of extended attributes.
Current mainline implementation of hfsplus file system driver treats as
extended attributes only two fields (fdType and fdCreator) of user_info
field in file description record (struct hfsplus_cat_file). It is
possible to get or set only these two fields as extended attributes.
But HFS+ treats as com.apple.FinderInfo extended attribute an union of
user_info and finder_info fields as for file (struct hfsplus_cat_file)
as for folder (struct hfsplus_cat_folder). Moreover, current mainline
implementation of hfsplus file system driver doesn't support special
metadata file - attributes tree.
Mac OS X 10.4 and later support extended attributes by making use of the
HFS+ filesystem Attributes file B*-tree feature which allows for named
forks. Mac OS X supports only inline extended attributes, limiting
their size to 3802 bytes. Any regular file may have a list of extended
attributes. HFS+ supports an arbitrary number of named forks. Each
attribute is denoted by a name and the associated data. The name is a
null-terminated Unicode string. It is possible to list, to get, to set,
and to remove extended attributes from files or directories.
It exists some peculiarity during getting of extended attributes list by
means of getfattr utility. The getfattr utility expects prefix "user."
before any extended attribute's name. So, it ignores any names that
don't contained such prefix. Such behavior of getfattr utility results
in unexpected empty output of extended attributes list even in the case
when file (or folder) contains extended attributes. It needs to use
empty string as regular expression pattern for names matching (getfattr
--match="").
For support of extended attributes in HFS+:
1. It was added necessary on-disk layout declarations related to Attributes
tree into hfsplus_raw.h file.
2. It was added attributes.c file with implementation of functionality of
manipulation by records in Attributes tree.
3. It was reworked hfsplus_listxattr, hfsplus_getxattr, hfsplus_setxattr
functions in ioctl.c. Moreover, it was added hfsplus_removexattr method.
This patch:
Add osx.* prefix for handling namespace of Mac OS X extended attributes.

The intent is to ensure that all Tegra-related patches are sent to the
linux-tegra@ mailing list, so people can keep up-to-date on all misc
driver changes.
Doing this with a keyword is far simpler and more compact than listing
all Tegra-related drivers, even if wildcards were used.
Words such as integrate or integrator are common. Ensure the character
right before "tegra" isn't a-z (case-insensitive), to make sure the
keyword doesn't match those.
The only files that the keyword doesn't match are the NVEC driver. Add
the linux-tegra mailing list to the NVEC entry to solve this.

Allow K: entries in MAINTAINERS to match directly against filenames;
either those extracted from patch +++ or --- lines, or those specified
on the command-line using the -f option.
This potentially allows fewer lines in a MAINTAINERS entry, if all the
relevant files are scattered throughout the whole kernel tree, yet
contain some common keyword. An example would be using an ARM SoC name
as the keyword to catch all related drivers.
I don't think setting exact_pattern_match_hash would be appropriate
here; at least for intended Tegra use case, this feature is to ensure
that all Tegra-related driver changes get Cc'd to the Tegra mailing
list. Setting exact_pattern_match_hash would prevent git history
parsing for e.g. S-o-b tags, which still seems like it would be useful.
Hence, this flag isn't set.

ocfs2_block_group_alloc_discontig() disables chain relink by setting
ac->ac_allow_chain_relink = 0 because it grabs clusters from multiple
cluster groups.
It doesn't keep the credits for all chain relink,but
ocfs2_claim_suballoc_bits overrides this in this call trace:
ocfs2_block_group_claim_bits()->ocfs2_claim_clusters()->
__ocfs2_claim_clusters()->ocfs2_claim_suballoc_bits()
ocfs2_claim_suballoc_bits set ac->ac_allow_chain_relink = 1; then call
ocfs2_search_chain() one time and disable it again, and then we run out
of credits.
Fix is to allow relink by default and disable it in
ocfs2_block_group_alloc_discontig.

We need to re-initialize the security for a new reflinked inode with its
parent dirs if it isn't specified to be preserved for ocfs2_reflink().
However, the code logic is broken at ocfs2_init_security_and_acl()
although ocfs2_init_security_get() succeed. As a result,
ocfs2_acl_init() does not involked and therefore the default ACL of
parent dir was missing on the new inode.
Note this was introduced by 9d8f13ba3 ("security: new
security_inode_init_security API adds function callback")
To reproduce:
set default ACL for the parent dir(ocfs2 in this case):
$ setfacl -m default:user:jeff:rwx ../ocfs2/
$ getfacl ../ocfs2/
# file: ../ocfs2/
# owner: jeff
# group: jeff
user::rwx
group::r-x
other::r-x
default:user::rwx
default:user:jeff:rwx
default:group::r-x
default😷:rwx
default:other::r-x
$ touch a
$ getfacl a
# file: a
# owner: jeff
# group: jeff
user::rw-
group::rw-
other::r--
Before patching, create reflink file b from a, the user
default ACL entry(user:jeff:rwx)was missing:
$ ./ocfs2_reflink a b
$ getfacl b
# file: b
# owner: jeff
# group: jeff
user::rw-
group::rw-
other::r--
In this case, the end user can also observed an error message at syslog:
(ocfs2_reflink,3229,2):ocfs2_init_security_and_acl:7193 ERROR: status = 0
After applying this patch, create reflink file c from a:
$ ./ocfs2_reflink a c
$ getfacl c
# file: c
# owner: jeff

Commit ef5da59f12 ("scripts/kernel-doc: handle struct member
__aligned") permits "char something [123] __aligned(8);".
However, by using \d we constraint ourselves with integers. This is not
always the case. In fact, it might be better to do char something[123]
__aligned(sizeof(u16));
For example, With wireless_dev defining:
u8 address[ETH_ALEN] __aligned(sizeof(u16));
With \d, scripts/kernel-doc erroneously says:
Warning(include/net/cfg80211.h:2618): Excess struct/union/enum/typedef member 'address' description in 'wireless_dev'
This is because the regex __aligned\s*\(\d+\) fails match at \d as
sizeof is used.
So replace \d with . to indicate "something" in kernel-doc to ignore
__aligned(SOMETHING) in structs. With this change, we can use integers
OR sizeof() or macros as we please.

provided to some boards using ams369fg06 panel, thus in this case, power
on/off sequence is not necessary.

"Additional x86 fixes. Three of these patches are pure documentation,
two are pretty trivial; the remaining one fixes boot problems on some
non-BIOS machines."

doc, xen: Mention 'earlyprintk=xen' in the documentation.
ACPI: Overriding ACPI tables via initrd only works with an initrd and on X86
On non-BIOS platforms it is possible that the BIOS data area contains
garbage instead of being zeroed or something equivalent (firmware
people: we are talking of 1.5K here, so please do the sane thing.)
We need on the order of 20-30K of low memory in order to boot, which
may grow up to < 64K in the future. We probably want to avoid the
lowest of the low memory. At the same time, it seems extremely
unlikely that a legitimate EBDA would ever reach down to the 128K
(which would require it to be over half a megabyte in size.) Thus,
pick 128K as the cutoff for "this is insane, ignore." We may still
end up reserving a bunch of extra memory on the low megabyte, but that
is not really a major issue these days. In the worst case we lose
512K of RAM.
This code really should be merged with trim_bios_range() in
arch/x86/kernel/setup.c, but that is a bigger patch for a later merge
window.

Pull ext4 regression fix from Theodore Ts'o:
"This fixes a real brown paper bag bug which causes ext4 to choke on
file systems larger than 512GB."
* tag 'ext4_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4:
ext4: fix extent status tree regression for file systems > 512GB
This fixes a regression introduced by commit f7fec032aa. The
problem was that the extents status flags caused us to mask out block
numbers smaller than 2**28 blocks. Since we didn't test with file
systems smaller than 512GB, we didn't notice this during the
development cycle.
A typical failure looks like this:
EXT4-fs error (device sdb1): htree_dirblock_to_tree:919: inode #172235804: block
152052301: comm ls: bad entry in directory: rec_len is smaller than minimal -
offset=0(0), inode=0, rec_len=0, name_len=0
... where 'debugfs -R "stat <172235804>" /dev/sdb1' reports that the
inode has block number 688923213. When viewed in hex, block number
152052301 (from the syslog) is 0x910224D, while block number 688923213
is 0x2910224D. Note the missing "0x20000000" in the block number.

When taking an address of an extern array, gcc quite naturally should be
able to say "an address of an object can never be NULL" and just
optimize away the test entirely.
However, the new alternate sysrq reset code (commit 154b7a489a:
"Input: sysrq - allow specifying alternate reset sequence") did exactly
that, and declared platform_sysrq_reset_seq[] as a weak array, and
expecting that testing the address of the array would show whether it
actually got linked against something or not.
And that doesn't work with all gcc versions. Clearly it works with
*some* versions of gcc, and maybe it's even supposed to work, but it
really is a very fragile concept.
So instead of testing the address of the weak variable, just create a
weak instance of that array that is empty. If some platform then has a
real platform_sysrq_reset_seq[] that overrides our weak one, the linker
will switch to that one, and it all works without any run-time
conditionals at all.

The stack vma is designed to grow automatically (marked with VM_GROWSUP
or VM_GROWSDOWN depending on architecture) when an access is made beyond
the existing boundary. However, particularly if you have not limited
your stack at all ("ulimit -s unlimited"), this can cause the stack to
grow even if the access was really just one past *another* segment.
And that's wrong, especially since we first grow the segment, but then
immediately later enforce the stack guard page on the last page of the
segment. So _despite_ first growing the stack segment as a result of
the access, the kernel will then make the access cause a SIGSEGV anyway!
So do the same logic as the guard page check does, and consider an
access to within one page of the next segment to be a bad access, rather
than growing the stack to abut the next segment.
