Section [A-Z]: patterns are not currently in any required sorting order.
Add a specific sorting sequence to MAINTAINERS entries.
Sort F: and X: patterns in alphabetic order.
The preferred section ordering is:
SECTION HEADER
M: Maintainers
R: Reviewers
P: Named persons without email addresses
L: Mailing list addresses
S: Status of this section (Supported, Maintained, Orphan, etc...)
W: Any relevant URLs
T: Source code control type (git, quilt, etc)
Q: Patchwork patch acceptance queue site
B: Bug tracking URIs
C: Chat URIs
F: Files with wildcard patterns (alphabetic ordered)
X: Excluded files with wildcard patterns (alphabetic ordered)
N: Files with regex patterns
K: Keyword regexes in source code for maintainership identification
Miscellaneous perl neatening:
- Rename %map to %hash, map has a different meaning in perl
- Avoid using \& and local variables for function indirection
- Use return for a little c like clarity
- Use c-like function call style instead of &function

Allow for MAINTAINERS to become a directory and if it is,
read all the files in the directory for maintained sections.
Optionally look for all files named MAINTAINERS in directories
excluding the .git directory by using --find-maintainer-files.
This optional feature adds ~.3 seconds of CPU on an Intel
i5-6200 with an SSD.
Miscellanea:
- Create a read_maintainer_file subroutine from the existing code
- Test only the existence of MAINTAINERS, not whether it's a file

Fix the warning message on the parisc and IA64 architectures to show the
correct function name of the caller by using %pS instead of %pF. The
message is printed with the value of _RET_IP_ which calls
__builtin_return_address(0) and as such returns the IP address caller
instead of pointer to a function descriptor of the caller.
The effect of this patch is visible on the parisc and ia64 architectures
only since those are the ones which use function descriptors while on
all others %pS and %pF will behave the same.

The synchronization type that was used earlier to guard the loop that
deletes unused log buffers may lead to a situation that prevents any
thread from going through the loop.
The patch deletes previously used synchronization mechanism and moves
the loop under the spin_lock so the similar cases won't be feasible in
the future.

On L3, the qeth_hdr struct needs to be filled with the next-hop
IP address.
The current code accesses rtable->rt_gateway without checking that
rtable is a valid address. The accidental access to a lowcore area
results in a random next-hop address in the qeth_hdr.
rtable (or more precisely, skb_dst(skb)) can be NULL in rare cases
(for instance together with AF_PACKET sockets).
This patch adds the missing NULL-ptr checks.

IPoIB fixes for 4.13
The patchset provides various fixes for IPoIB. It is combination of
fixes to various issues discovered during verification along with
static checkers cleanup patches.
Most of the patches are from pre-git era and hence lack of Fixes lines.
There is one exception in this IPoIB group - addition of patch revert:
Revert "IB/core: Allow QP state transition from reset to error", but
it followed by proper fix to the annoying print, so I thought it is
appropriate to include it.

====================
asix: Improve robustness
Please consider taking these patches to improve the robustness of the ASIX USB
to Ethernet driver.
Failures prompting an ASIX driver code review
=============================================
On an ARM i.MX6 embedded platform some strange one-off and two-off failures were
observed in and around the ASIX USB to Ethernet driver. This was observed on a
highly modified kernel 3.14 with the ASIX driver containing back-ported changes
from kernel.org up to kernel 4.8 approximately.
a) A one-off failure in asix_rx_fixup_internal():
There was an occurrence of an attempt to write off the end of the netdev buffer
which was trapped by skb_over_panic() in skb_put().

[20031.365528] [<80008510>] (gic_handle_irq) from [<8050de80>] (__irq_svc+0x40/0x70)
Analysis of the logic of the ASIX driver (containing backported changes from
kernel.org up to kernel 4.8 approximately) suggested that the software could not
trigger skb_over_panic(). The analysis of the kernel BUG() crash information
suggested that the netdev buffer was written with 2 minimal 60 octet length
Ethernet frames (ASIX hardware drops the 4 octet FCS field) and the 2nd Ethernet
frame attempted to write off the end of the netdev buffer.
Note that the netdev buffer should only contain 1 Ethernet frame so if an
attempt to write 2 Ethernet frames into the buffer is made then that is wrong.
However, the logic of the asix_rx_fixup_internal() only allows 1 Ethernet frame
to be written into the netdev buffer.
Potentially this failure was due to memory corruption because it was only seen
once.
b) Two-off failures in the NAPI layer's backlog queue:
There were 2 crashes in the NAPI layer's backlog queue presumably after
asix_rx_fixup_internal() called usbnet_skb_return().

The embedded board was only using an ASIX USB to Ethernet adaptor eth0.
Analysis suggested that the doubly-linked list pointers of the backlog queue had
been corrupted because one of the link pointers was NULL.
Potentially this failure was due to memory corruption because it was only seen
twice.
Results of the ASIX driver code review
======================================
During the code review some weaknesses were observed in the ASIX driver and the
following patches have been created to improve the robustness.
Brief overview of the patches
-----------------------------
1. asix: Add rx->ax_skb = NULL after usbnet_skb_return()
The current ASIX driver sends the received Ethernet frame to the NAPI layer of
the network stack via the call to usbnet_skb_return() in
asix_rx_fixup_internal() but retains the rx->ax_skb pointer to the netdev
buffer. The driver no longer needs the rx->ax_skb pointer at this point because
the NAPI layer now has the Ethernet frame.
This means that asix_rx_fixup_internal() must not use rx->ax_skb after the call
to usbnet_skb_return() because it could corrupt the handling of the Ethernet
frame within the network layer.
Therefore, to remove the risk of erroneous usage of rx->ax_skb, set rx->ax_skb
to NULL after the call to usbnet_skb_return(). This avoids potential erroneous
freeing of rx->ax_skb and erroneous writing to the netdev buffer. If the
software now somehow inappropriately reused rx->ax_skb, then a NULL pointer
dereference of rx->ax_skb would occur which makes investigation easier.
2. asix: Ensure asix_rx_fixup_info members are all reset
This patch creates reset_asix_rx_fixup_info() to allow all the
asix_rx_fixup_info structure members to be consistently reset to initial
conditions.
Call reset_asix_rx_fixup_info() upon each detectable error condition so that the
next URB is processed from a known state.
Otherwise, there is a risk that some members of the asix_rx_fixup_info structure
may be incorrect after an error occurred so potentially leading to a
malfunction.
3. asix: Fix small memory leak in ax88772_unbind()
This patch creates asix_rx_fixup_common_free() to allow the rx->ax_skb to be
freed when necessary.
asix_rx_fixup_common_free() is called from ax88772_unbind() before the parent
private data structure is freed.
Without this patch, there is a risk of a small netdev buffer memory leak each
time ax88772_unbind() is called during the reception of an Ethernet frame that
spans across 2 URBs.
Testing
=======
The patches have been sanity tested on a 64-bit Linux laptop running kernel
4.13-rc2 with the 3 patches applied on top.
The ASIX USB to Adaptor used for testing was (output of lsusb):
ID 0b95:772b ASIX Electronics Corp. AX88772B
Test #1
-------
The test ran a flood ping test script which slowly incremented the ICMP Echo
Request's payload from 0 to 5000 octets. This eventually causes IPv4
fragmentation to occur which causes Ethernet frames to be sent very close to
each other so increases the probability that an Ethernet frame will span 2 URBs.
The test showed that all pings were successful. The test took about 15 minutes
to complete.
Test #2
-------
A script was run on the laptop to periodically run ifdown and ifup every second
so that the ASIX USB to Adaptor was up for 1 second and down for 1 second.
From a Linux PC connected to the laptop, the following ping command was used
ping -f -s 5000 <ip address of laptop>
The large ICMP payload causes IPv4 fragmentation resulting in multiple
Ethernet frames per original IP packet.
Kernel debug within the ASIX driver was enabled to see whether any ASIX errors
were generated. The test was run for about 24 hours and no ASIX errors were
seen.
Patches
=======
The 3 patches have been rebased off the net-next repo master branch with HEAD

When Ethernet frames span mulitple URBs, the netdev buffer memory
pointed to by the asix_rx_fixup_info structure remains allocated
during the time gap between the 2 executions of asix_rx_fixup_internal().
This means that if ax88772_unbind() is called within this time
gap to free the memory of the parent private data structure then
a memory leak of the part filled netdev buffer memory will occur.
Therefore, create a new function asix_rx_fixup_common_free() to
free the memory of the netdev buffer and add a call to
asix_rx_fixup_common_free() from inside ax88772_unbind().
Consequently when an unbind occurs part way through receiving
an Ethernet frame, the netdev buffer memory that is holding part
of the received Ethernet frame will now be freed.

There is a risk that the members of the structure asix_rx_fixup_info
become unsynchronised leading to the possibility of a malfunction.
For example, rx->split_head was not being set to false after an
error was detected so potentially could cause a malformed 32-bit
Data header word to be formed.
Therefore add function reset_asix_rx_fixup_info() to reset all the
members of asix_rx_fixup_info so that future processing will start
with known initial conditions.
Also, if (skb->len != offset) becomes true then call
reset_asix_rx_fixup_info() so that the processing of the next URB
starts with known initial conditions. Without the call, the check
does nothing which potentially could lead to a malfunction
when the next URB is processed.
In addition, for robustness, call reset_asix_rx_fixup_info() before
every error path's "return 0". This ensures that the next URB is
processed from known initial conditions.

In asix_rx_fixup_internal() there is a risk that rx->ax_skb gets
reused after passing the Ethernet frame into the network stack via
usbnet_skb_return().
The risks include:
a) asynchronously freeing rx->ax_skb after passing the netdev buffer
to the NAPI layer which might corrupt the backlog queue.
b) erroneously reusing rx->ax_skb such as calling skb_put_data() multiple
times which causes writing off the end of the netdev buffer.
Therefore add a defensive rx->ax_skb = NULL after usbnet_skb_return()
so that it is not possible to free rx->ax_skb or to apply
skb_put_data() too many times.

This is caused by a byte endianness issue. S390x is a big endian
architecture. Pointer access to the lowest byte or halfword of a
four byte value need to add an offset.
On little endian architectures this offset is not needed.
Fix this and use the same approach as the originator used for other files
(for example test_verifier.c) in his original commit.
With this fix the test program test_progs succeeds on s390x:

Pin 23 on South bridge does not belong to the rgmii group. It belongs to
a separate group which can have 3 functions.
Due to this the fix also have to update the way the functions are
managed. Until now each groups used NB_FUNCS(which was 2) functions. For
the mpp23, 3 functions are available but it is the only group which needs
it, so on the loop involving NB_FUNCS an extra test was added to handle
only the functions added.
The bug was visible with the merge of the commit 07d065abf93d "arm64:
dts: marvell: armada-3720-db: Add vqmmc regulator for SD slot", the gpio
regulator used the gpio 23, due to this the whole rgmii group was setup
to gpio which broke the Ethernet support on the Armada 3720 DB
board. Thanks to this patch, the UHS SD cards (which need the vqmmc)
_and_ the Ethernet work again.

The existing sub channel code did not wait for all the sub-channels
to completely initialize. This could lead to race causing crash
in napi_netif_del() from bad list. The existing code would send
an init message, then wait only for the initial response that
the init message was received. It thought it was waiting for
sub channels but really the init response did the wakeup.
The new code keeps track of the number of open channels and
waits until that many are open.
Other issues here were:
* host might return less sub-channels than was requested.
* the new init status is not valid until after init was completed.

The latest change of compat_sys_sigpending in commit 8f13621abced
("sigpending(): move compat to native") has broken it in two ways.
First, it tries to write 4 bytes more than userspace expects:
sizeof(old_sigset_t) == sizeof(long) == 8 instead of
sizeof(compat_old_sigset_t) == sizeof(u32) == 4.
Second, on big endian architectures these bytes are being written in the
wrong order.
This bug was found by strace test suite.

ext4_xattr_inode_read() currently reads each block sequentially while
waiting for io operation to complete before moving on to the next
block. This prevents request merging in block layer.

then optionally waits for them to complete. A similar logic is used
in ext4_find_entry(), so update that code to use the new function.

When an xattr block has a single reference, block is updated inplace
and it is reinserted to the cache. Later, a cache lookup is performed
to see whether an existing block has the same contents. This cache
lookup will most of the time return the just inserted entry so
deduplication is not achieved.
Running the following test script will produce two xattr blocks which
can be observed in "File ACL: " line of debugfs output:
mke2fs -b 1024 -I 128 -F -O extent /dev/sdb 1G
mount /dev/sdb /mnt/sdb
touch /mnt/sdb/{x,y}
setfattr -n user.1 -v aaa /mnt/sdb/x
setfattr -n user.2 -v bbb /mnt/sdb/x
setfattr -n user.1 -v aaa /mnt/sdb/y
setfattr -n user.2 -v bbb /mnt/sdb/y
debugfs -R 'stat x' /dev/sdb | cat
debugfs -R 'stat y' /dev/sdb | cat
This patch defers the reinsertion to the cache so that we can locate
other blocks with the same contents.

After commit 62d1034f53e3 ("fortify: use WARN instead of BUG for now"),
we get a warning about possible stack overflow from a memcpy that
was not strictly bounded to the size of the local variable:
inlined from 'ext4_mb_seq_groups_show' at fs/ext4/mballoc.c:2322:2:
include/linux/string.h:309:9: error: '__builtin_memcpy': writing between 161 and 1116 bytes into a region of size 160 overflows the destination [-Werror=stringop-overflow=]
We actually had a bug here that would have been found by the warning,
but it was already fixed last year in commit 30a9d7afe70e ("ext4: fix
stack memory corruption with 64k block size").
This replaces the fixed-length structure on the stack with a variable-length
structure, using the correct upper bound that tells the compiler that
everything is really fine here. I also change the loop count to check
for the same upper bound for consistency, but the existing code is
already correct here.
Note that while clang won't allow certain kinds of variable-length arrays
in structures, this particular instance is fine, as the array is at the
end of the structure, and the size is strictly bounded.

The dir_nlink feature has been enabled by default for new ext4
filesystems since e2fsprogs-1.41 in 2008, and was automatically
enabled by the kernel for older ext4 filesystems since the
dir_nlink feature was added with ext4 in kernel 2.6.28+ when
the subdirectory count exceeded EXT4_LINK_MAX-1.
Automatically adding the file system features such as dir_nlink is
generally frowned upon, since it could cause the file system to not be
mountable on older kernel, thus preventing the administrator from
rolling back to an older kernel if necessary.
In this case, the administrator might also want to disable the feature
because glibc's fts_read() function does not correctly optimize
directory traversal for directories that use st_nlinks field of 1 to
indicate that the number of links in the directory are not tracked by
the file system, and could fail to traverse the full directory
hierarchy. Fortunately, in the past ten years very few users have
complained about incomplete file system traversal by glibc's
fts_read().
This commit also changes ext4_inc_count() to allow i_nlinks to reach
the full EXT4_LINK_MAX links on the parent directory (including "."
and "..") before changing i_links_count to be 1.

ext4_find_unwritten_pgoff() does not properly handle a situation when
starting index is in the middle of a page and blocksize < pagesize. The
following command shows the bug on filesystem with 1k blocksize:
xfs_io -f -c "falloc 0 4k" \
-c "pwrite 1k 1k" \
-c "pwrite 3k 1k" \
-c "seek -a -r 0" foo
In this example, neither lseek(fd, 1024, SEEK_HOLE) nor lseek(fd, 2048,
SEEK_DATA) will return the correct result.
Fix the problem by neglecting buffers in a page before starting offset.

This fixes a problem where the system gets stuck in a loop
unable to wakeup via power button in s2idle.
The problem happens because:
- press power button:
- system emits 0xc0 (power press), event ignored
- system emits 0xc1 (power release), event processed,
emited as KEY_POWER
- set wakeup_mode to true
- system goes to s2idle
- press power button
- system emits 0xc0 (power press), wakeup_mode is true,
system wakes
- system emits 0xc1 (power release), event processed,
emited as KEY_POWER
- system goes to s2idle again
To avoid this situation, process the presses (which matches what
intel-hid does too).

We've changed the discard command handling into parallel manner.
But, in this change, I forgot decreasing the usage count of the bio
which was used to send discard request. I'm sorry about that.
Fixes: a015434480dc ("ext4: send parallel discards on commit completions")

Pull GPIO fixes from Linus Walleij:
- LP87565: set the proper output level for direction_output.
- stm32: fix the kernel build by selecting the hierarchical irqdomain
symbol properly - this happens to be done in the pin control
framework but whatever, it had dependencies to GPIO so we need to
apply it here.
- Select the hierarchical IRQ domain also for Xgene.
- Fix wakeups to work on MXC.
- Fix up the device tree binding on Exar that went astray, also add the
right bindings.
- Fix the unwanted events for edges from the library.
- Fix the unbalanced chanined IRQ on the Tegra.

Pull clk fixes from Stephen Boyd:
"A handful of critical fixes for changes introduce this merge window.
- The TI sci_clk_get() API was pretty broken and nobody noticed.
- There were some CPUfreq crashes on C.H.I.P devices because we
failed to propagate rates up the clk tree.
- Also, the Intel Atom PMC clk driver needs to mark a clk critical if
the firmware has it enabled already so that audio doesn't get
killed on Baytrail.
- Gemini devices have a dead serial console because the reset control
usage in the serial driver assume one method of reset that gemini
doesn't support (this will be fixed in the next version in the
reset framework so this is the small fix for -rc series).
- Finally we have two rate calculation fixes, one for Exynos and one
for Meson SoCs, that fix rate inconsistencies"
