Heiner Kallweit 34d9810b31 HID: hid-led: remove report id from struct hidled_config
Delcom uses the report id to submit command information. To be able to
use the hidled framework also for Delcom devices we have to remove the
report id from struct hidled_config.

Jiri Kosina 26423b84a3 HID: led: fix config
The driver port was done carefully not to depend on USB at all, in favor of
being generic HID driver instead. Therefore there is no need to explicitly
talk about USB only in the config.

Heiner Kallweit a335aaf312 usb: misc: remove outdated USB LED driver
The USB LED driver exposes a undocumented sysfs interface and doesn't
use the standard kernel LED subsystem. It supports three devices:

Delcom Visual Signal Indicator
The driver supports generation 1 of the device only which was
manufactured until 2008. Remove support for this device completely.

Riso Kagaku RGB LED + Dream Cheeky Webmail Notifier
These devices are HID compliant and are supported by a new USB LED
driver under drivers/hid utilizing the kernel LED subsystem.

So let's remove the old USB LED driver.

Heiner Kallweit 6c7ad07e9e HID: migrate USB LED driver from usb misc to hid
This patch migrates the USB LED driver to the HID subsystem.
Supported are Dream Cheeky Webmail Notifier / Friends Alert
and Riso Kagaku Webmail Notifier.

Benefits:
- Avoid using USB low-level calls and use the HID subsystem instead
  (as this device provides a USB HID interface)
- Use standard LED subsystem instead of proprietary sysfs entries,
  this allows e.g. to use the device with features like triggers

Successfully tested with a Dream Cheeky Webmail Notifier and a
Riso Kagaku Webmail Notifier compatible device.

   - Fix for a long standing issue where wrong ordering in blk-mq caused
     order_to_size() to spew a warning.  From Bart.

   - Async discard support from Christoph.  Basically just splitting our
     sync interface into a submit + wait part.

   - Add a cleaner interface for flagging whether a device has a write
     back cache or not.  We've previously overloaded blk_queue_flush()
     with this, but let's make it more explicit.  Drivers cleaned up and
     updated in the drivers pull request.  From me.

   - Fix for a double check for whether IO accounting is enabled or not.
     From Michael Callahan.

   - Fix for the async discard from Mike Snitzer, reinstating the early
     EOPNOTSUPP return if the device doesn't support discards.

   - Also from Mike, export bio_inc_remaining() so dm can drop it's
     private copy of it.

   - From Ming Lin, add support for passing in an offset for request
     payloads.

   - Tag function export from Sagi, which will be used in NVMe in the
     drivers pull.

   - Two blktrace related fixes from Shaohua.

   - Propagate NOMERGE flag when making a request from a bio, also from

Ard Biesheuvel 27896c83fe r8169: default to 64-bit DMA on recent PCIe chips
The current logic around the 'use_dac' module parameter prevents the
r81969 driver from being loadable on 64-bit systems without any RAM
below 4 GB when the parameter is left at its default value.

So introduce a new default value -1 which indicates that 64-bit DMA
should be enabled on sufficiently recent PCIe chips, i.e., versions
RTL_GIGA_MAC_VER_18 or later. Explicit param values of 0 or 1 retain
the existing behavior of unconditionally enabling/disabling 64-bit DMA
on 64-bit architectures (i.e., regardless of the type and version of the
chip)

Since PCIe chips do not need to CPlusCmd Dual Address Cycle to be set,
make that conditional on the device type as well.

Alexander Graf 81003bc924 phy dp83867: Make rgmii parameters optional
If you compile without OF_MDIO support in an RGMII configuration, we fail
to configure the dp83867 phy today by writing garbage into its configuration
registers.

On the other hand if you do compile with OF_MDIO and the phy gets loaded via
device tree, you have to have the properties set in the device tree, otherwise
we fail to load the driver and don't even attach the generic phy driver to
the interface anymore.

To make things slightly more consistent, make the rgmii configuration properties
optional and allow a user to omit them in their device tree.

Alexander Graf 7f32541c2f phy dp83867: Fix compilation with CONFIG_OF_MDIO=m
When CONFIG_OF_MDIO is configured as module, the #define for it really
is CONFIG_OF_MDIO_MODULE, not CONFIG_OF_MDIO. So if we are compiling it
as module, the dp83867 doesn't see that OF_MDIO was selected and doesn't
read the dt rgmii parameters.

The fix is simple: Use IS_ENABLED(). It checks for both - module as well
as compiled in code.

Yang Shi 4c1cd4fdfd bpf: arm64: remove callee-save registers use for tmp registers
In the current implementation of ARM64 eBPF JIT, R23 and R24 are used for
tmp registers, which are callee-saved registers. This leads to variable size
of JIT prologue and epilogue. The latest blinding constant change prefers to
constant size of prologue and epilogue. AAPCS reserves R9 ~ R15 for temp
registers which not need to be saved/restored during function call. So, replace
R23 and R24 to R10 and R11, and remove tmp_used flag to save 2 instructions for
some jited BPF program.

John Stultz cd9e2e5d3f asix: Fix offset calculation in asix_rx_fixup() causing slow transmissions
In testing with HiKey, we found that since
commit 3f30b158eb ("asix: On RX avoid creating bad Ethernet
frames"),
we're seeing lots of noise during network transfers:

[  239.027993] asix 1-1.1:1.0 eth0: asix_rx_fixup() Data Header synchronisation was lost, remaining 988
[  239.037310] asix 1-1.1:1.0 eth0: asix_rx_fixup() Bad Header Length 0x54ebb5ec, offset 4
[  239.045519] asix 1-1.1:1.0 eth0: asix_rx_fixup() Bad Header Length 0xcdffe7a2, offset 4
[  239.275044] asix 1-1.1:1.0 eth0: asix_rx_fixup() Data Header synchronisation was lost, remaining 988
[  239.284355] asix 1-1.1:1.0 eth0: asix_rx_fixup() Bad Header Length 0x1d36f59d, offset 4
[  239.292541] asix 1-1.1:1.0 eth0: asix_rx_fixup() Bad Header Length 0xaef3c1e9, offset 4
[  239.518996] asix 1-1.1:1.0 eth0: asix_rx_fixup() Data Header synchronisation was lost, remaining 988
[  239.528300] asix 1-1.1:1.0 eth0: asix_rx_fixup() Bad Header Length 0x2881912, offset 4
[  239.536413] asix 1-1.1:1.0 eth0: asix_rx_fixup() Bad Header Length 0x5638f7e2, offset 4

And network throughput ends up being pretty bursty and slow with
a overall throughput of at best ~30kB/s (where as previously we
got 1.1MB/s with the slower USB1.1 "full speed" host).

We found the issue also was reproducible on a x86_64 system,
using a "high-speed" USB2.0 port but the throughput did not
measurably drop (possibly due to the scp transfer being cpu
bound on my slow test hardware).

After lots of debugging, I found the check added in the
problematic commit seems to be calculating the offset
incorrectly.

In the normal case, in the main loop of the function, we do:
(where offset is zero, or set to "offset += (copy_length + 1) &
0xfffe" in the previous loop)
    rx->header = get_unaligned_le32(skb->data +
                                    offset);
    offset += sizeof(u32);

But the problematic patch calculates:
    offset = ((rx->remaining + 1) & 0xfffe) + sizeof(u32);
    rx->header = get_unaligned_le32(skb->data + offset);

Adding some debug logic to check those offset calculation used
to find rx->header, the one in problematic code is always too
large by sizeof(u32).

Thus, this patch removes the incorrect " + sizeof(u32)" addition
in the problematic calculation, and resolves the issue.

Linus Torvalds 7f427d3a60 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
Pull parallel filesystem directory handling update from Al Viro.

This is the main parallel directory work by Al that makes the vfs layer
able to do lookup and readdir in parallel within a single directory.
That's a big change, since this used to be all protected by the
directory inode mutex.

The inode mutex is replaced by an rwsem, and serialization of lookups of
a single name is done by a "in-progress" dentry marker.

The series begins with xattr cleanups, and then ends with switching
filesystems over to actually doing the readdir in parallel (switching to
the "iterate_shared()" that only takes the read lock).

A more detailed explanation of the process from Al Viro:
 "The xattr work starts with some acl fixes, then switches ->getxattr to
  passing inode and dentry separately.  This is the point where the
  things start to get tricky - that got merged into the very beginning
  of the -rc3-based #work.lookups, to allow untangling the
  security_d_instantiate() mess.  The xattr work itself proceeds to
  switch a lot of filesystems to generic_...xattr(); no complications
  there.

  After that initial xattr work, the series then does the following:

   - untangle security_d_instantiate()

   - convert a bunch of open-coded lookup_one_len_unlocked() to calls of
     that thing; one such place (in overlayfs) actually yields a trivial
     conflict with overlayfs fixes later in the cycle - overlayfs ended
     up switching to a variant of lookup_one_len_unlocked() sans the
     permission checks.  I would've dropped that commit (it gets
     overridden on merge from #ovl-fixes in #for-next; proper resolution
     is to use the variant in mainline fs/overlayfs/super.c), but I
     didn't want to rebase the damn thing - it was fairly late in the
     cycle...

   - some filesystems had managed to depend on lookup/lookup exclusion
     for *fs-internal* data structures in a way that would break if we
     relaxed the VFS exclusion.  Fixing hadn't been hard, fortunately.

   - core of that series - parallel lookup machinery, replacing
     ->i_mutex with rwsem, making lookup_slow() take it only shared.  At
     that point lookups happen in parallel; lookups on the same name
     wait for the in-progress one to be done with that dentry.

     Surprisingly little code, at that - almost all of it is in
     fs/dcache.c, with fs/namei.c changes limited to lookup_slow() -
     making it use the new primitive and actually switching to locking
     shared.

   - parallel readdir stuff - first of all, we provide the exclusion on
     per-struct file basis, same as we do for read() vs lseek() for
     regular files.  That takes care of most of the needed exclusion in
     readdir/readdir; however, these guys are trickier than lookups, so
     I went for switching them one-by-one.  To do that, a new method
     '->iterate_shared()' is added and filesystems are switched to it
     as they are either confirmed to be OK with shared lock on directory
     or fixed to be OK with that.  I hope to kill the original method
     come next cycle (almost all in-tree filesystems are switched
     already), but it's still not quite finished.

   - several filesystems get switched to parallel readdir.  The
     interesting part here is dealing with dcache preseeding by readdir;
     that needs minor adjustment to be safe with directory locked only
     shared.

     Most of the filesystems doing that got switched to in those
     commits.  Important exception: NFS.  Turns out that NFS folks, with
     their, er, insistence on VFS getting the fuck out of the way of the
     Smart Filesystem Code That Knows How And What To Lock(tm) have
     grown the locking of their own.  They had their own homegrown
     rwsem, with lookup/readdir/atomic_open being *writers* (sillyunlink
     is the reader there).  Of course, with VFS getting the fuck out of
     the way, as requested, the actual smarts of the smart filesystem
     code etc. had become exposed...

   - do_last/lookup_open/atomic_open cleanups.  As the result, open()
     without O_CREAT locks the directory only shared.  Including the
     ->atomic_open() case.  Backmerge from #for-linus in the middle of
     that - atomic_open() fix got brought in.

   - then comes NFS switch to saner (VFS-based ;-) locking, killing the
     homegrown "lookup and readdir are writers" kinda-sorta rwsem.  All
     exclusion for sillyunlink/lookup is done by the parallel lookups
     mechanism.  Exclusion between sillyunlink and rmdir is a real rwsem
     now - rmdir being the writer.

     Result: NFS lookups/readdirs/O_CREAT-less opens happen in parallel
     now.

   - the rest of the series consists of switching a lot of filesystems
     to parallel readdir; in a lot of cases ->llseek() gets simplified
     as well.  One backmerge in there (again, #for-linus - rockridge
     fix)"

Jiri Pirko da4ed55165 switchdev: pass pointer to fib_info instead of copy
The problem is that fib_info->nh is [0] so the struct fib_info
allocation size depends on number of nexthops. If we just copy fib_info,
we do not copy the nexthops info and driver accesses memory which is not
ours.

Given the fact that fib4 does not defer operations and therefore it does
not need copy, just pass the pointer down to drivers as it was done
before.

Linus Torvalds 2fe2edf85f Hao Qin reported an integer overflow possibility with signed and
unsigned numbers in the ring-buffer code.
 
   https://bugzilla.kernel.org/show_bug.cgi?id=118001
 
 At first I did not think this was too much of an issue, because the
 overflow would be caught later when either too much data was allocated
 or it would trigger RB_WARN_ON() which shuts down the ring buffer.
 
 But looking closer into it, I found that the right settings could bypass
 the checks and crash the kernel. Luckily, this is only accessible
 by root.
 
 The first fix is to convert all the variables into long, such that
 we don't get into issues between 32 bit variables being assigned 64 bit
 ones. This fixes the RB_WARN_ON() triggering.
 
 The next fix is to get rid of a duplicate DIV_ROUND_UP() that when called
 twice with the right value, can cause a kernel crash.
 
 The first DIV_ROUND_UP() is to normalize the input and it is checked
 against the minimum allowable value. But then DIV_ROUND_UP() is called
 again, which can overflow due to the (a + b - 1)/b, logic. The first
 called upped the value, the second can overflow (with the +b part).
 
 The second call to DIV_ROUND_UP() came in via a second change a while ago
 and the code is cleaned up to remove it.

The action init code path is good because it is impossible to modify
an action that is being removed.

So, fix this by moving everything under the spinlock.

Harvey Hunt 3274940bd3 drivers: net: Don't print unpopulated net_device name
For ethernet devices, net_device.name will be eth%d before
register_netdev() is called. Don't print the net_device name until
the format string is replaced.

Sudarsana Reddy Kalluru 39651abd28 qed: add support for dcbx.
This patch adds the necessary driver support for Management Firmware to
configure the device/firmware with the dcbx results. Management Firmware
is responsible for communicating the DCBX and driving the negotiation,
but the driver has responsibility of receiving async notification and
configuring the results in hw/fw. This patch also adds the dcbx support for
future protocols (e.g., FCoE) as preparation to their imminent submission.

Geert Uytterhoeven ccf928249c ravb: Add missing free_irq() calls to ravb_close()
When reopening the network device on ra7795/salvator-x, e.g. after a
DHCP timeout:

    IP-Config: Reopening network devices...
    genirq: Flags mismatch irq 139. 00000000 (eth0:ch0:rx_be) vs. 00000000 (ravb e6800000.ethernet eth0: cannot request IRQ eth0:ch0:rx_be
    IP-Config: Failed to open eth0
    IP-Config: No network devices available

The "mismatch" is due to requesting an IRQ that is already in use,
while IRQF_PROBE_SHARED wasn't set.

However, the real cause is that ravb_close() doesn't release any of the
R-Car Gen3-specific secondary IRQs.

Add the missing free_irq() calls to fix this.

Jeff Kirsher says:

====================
10GbE Intel Wired LAN Driver Updates 2016-05-16

This series contains 2 fixes to ixgbe only.

Emil fixes transmit hangs when enabling SRIOV by swapping the parameters
in GENMASK in order to generate the correct mask.

Alex fixes his previous patch b83e30104b ("ixgbe/ixgbevf: Add support
for GSO partial") where he somehow transposed the location of setting
the VLAN features in netdev->features and the configuration of the
vlan_features.
