Mintz, Yuval 6f437d4319 qed: Don't use attention PTT for configuring BW
Commit 653d2ffd6405 ("qed*: Fix link indication race") introduced another
race - one of the inner functions called from the link-change flow is
explicitly using the slowpath context dedicated PTT instead of gaining
that PTT from the caller. Since this flow can now be called from
a different context as well, we're in risk of the PTT breaking.

Mintz, Yuval fd3c615ae1 qed: Fix race with multiple VFs
A PF syncronizes all IOV activity relating to its VFs
by using a single workqueue handling the work.
The workqueue would reach a bitmask of pending VF events
and act upon each in turn.

Problem is that the indication of a VF message [which sets
the 'vf event' bit for that VF] arrives and is set in
the slowpath attention context, which isn't syncronized with
the processing of the events.
When multiple VFs are present, it's possible that PF would
lose the indication of one of the VF's pending evens, leading
that VF to later timeout.

Instead of adding locks/barriers, simply move from a bitmask
into a per-VF indication inside that VF entry in the PF database.

====================
Netfilter fixes for net

The following patchset contains netfilter fixes for you net tree,
they are:

1) Missing ct zone size in the nft_ct initialization path, patch
   from Florian Westphal.

2) Two patches for netfilter uapi headers, one to remove unnecessary
   sysctl.h inclusion and another to fix compilation of xt_hashlimit.h
   in userspace, from Dmitry V. Levin.

3) Patch to fix a sloppy change in nf_ct_expect that incorrectly
   simplified nf_ct_expect_related_report() in the previous nf-next
   batch. This also includes another patch for __nf_ct_expect_check()
   to report success by returning 0 to keep it consistent with other
   existing functions. From Jarno Rajahalme.

4) The ->walk() iterator of the new bitmap set type goes over the real
   bitmap size, this results in incorrect dumps when NFTA_SET_USERDATA
   is used.

Fix xfrm_neigh_lookup to provide dst->path to the
neigh_lookup dst_ops method.

When skb is provided, the IP address in packet should already
match the dst->path address family. But for the non-skb case,
we should consider the last tunnel address as nexthop address.

David Howells d7e15835ab rxrpc: Kernel calls get stuck in recvmsg
Calls made through the in-kernel interface can end up getting stuck because
of a missed variable update in a loop in rxrpc_recvmsg_data().  The problem
is like this:

 (1) A new packet comes in and doesn't cause a notification to be given to
     the client as there's still another packet in the ring - the
     assumption being that if the client will keep drawing off data until
     the ring is empty.

 (2) The client is in rxrpc_recvmsg_data(), inside the big while loop that
     iterates through the packets.  This copies the window pointers into
     variables rather than using the information in the call struct
     because:

     (a) MSG_PEEK might be in effect;

     (b) we need a barrier after reading call->rx_top to pair with the
     	 barrier in the softirq routine that loads the buffer.

 (3) The reading of call->rx_top is done outside of the loop, and top is
     never updated whilst we're in the loop.  This means that even through
     there's a new packet available, we don't see it and may return -EFAULT
     to the caller - who will happily return to the scheduler and await the
     next notification.

 (4) No further notifications are forthcoming until there's an abort as the
     ring isn't empty.

The fix is to move the read of call->rx_top inside the loop - but it needs
to be done before the condition is checked.

Roman Mashak edb9d1bff4 net sched actions: decrement module reference count after table flush.
When tc actions are loaded as a module and no actions have been installed,
flushing them would result in actions removed from the memory, but modules
reference count not being decremented, so that the modules would not be
unloaded.

Following is example with GACT action:

% sudo modprobe act_gact
% lsmod

act_gact               16384  0

Xin Long 99253eb750 ipv6: check sk sk_type and protocol early in ip_mroute_set/getsockopt
Commit 5e1859fbcc ("ipv4: ipmr: various fixes and cleanups") fixed
the issue for ipv4 ipmr:

  ip_mroute_setsockopt() & ip_mroute_getsockopt() should not
  access/set raw_sk(sk)->ipmr_table before making sure the socket
  is a raw socket, and protocol is IGMP

The same fix should be done for ipv6 ipmr as well.

This patch can fix the panic caused by overwriting the same offset
as ipmr_table as in raw_sk(sk) when accessing other type's socket
by ip_mroute_setsockopt().

Xin Long 2e3ce5bc2a sctp: set sin_port for addr param when checking duplicate address
Commit b8607805dd ("sctp: not copying duplicate addrs to the assoc's
bind address list") tried to check for duplicate address before copying
to asoc's bind_addr list from global addr list.

But all the addrs' sin_ports in global addr list are 0 while the addrs'
sin_ports are bp->port in asoc's bind_addr list. It means even if it's
a duplicate address, af->cmp_addr will still return 0 as the their
sin_ports are different.

This patch is to fix it by setting the sin_port for addr param with
bp->port before comparing the addrs.

Eric Dumazet 47d3a07528 net/mlx4_en: fix overflow in mlx4_en_init_timestamp()
The cited commit makes a great job of finding optimal shift/multiplier
values assuming a 10 seconds wrap around, but forgot to change the
overflow_period computation.

It overflows in cyclecounter_cyc2ns(), and the final result is 804 ms,
which is silly.

Lets simply use 5 seconds, no need to recompute this, given how it is
supposed to work.

Later, we will use a timer instead of a work queue, since the new RX
allocation schem will no longer need mlx4_en_recover_from_oom() and the
service_task firing every 250 ms.

Brian Russell 1158632b5a vxlan: don't allow overwrite of config src addr
When using IPv6 transport and a default dst, a pointer to the configured
source address is passed into the route lookup. If no source address is
configured, then the value is overwritten.

IPv6 route lookup ignores egress ifindex match if the source address is set,
so if egress ifindex match is desired, the source address must be passed
as any. The overwrite breaks this for subsequent lookups.

Avoid this by copying the configured address to an existing stack variable
and pass a pointer to that instead.

Marc Dionne 774521f353 rxrpc: Fix an assertion in rxrpc_read()
In the rxrpc_read() function, which allows a user to read the contents of a
key, we miscalculate the expected length of an encoded rxkad token by not
taking into account the key length.  However, the data is stored later
anyway with an ENCODE_DATA() call - and an assertion failure then ensues
when the lengths are checked at the end.

Fix this by including the key length in the token size estimation.

The following assertion is produced:

Assertion failed - 384(0x180) == 380(0x17c) is false

Marcelo Ricardo Leitner dfcb9f4f99 sctp: deny peeloff operation on asocs with threads sleeping on it
commit 2dcab59848 ("sctp: avoid BUG_ON on sctp_wait_for_sndbuf")
attempted to avoid a BUG_ON call when the association being used for a
sendmsg() is blocked waiting for more sndbuf and another thread did a
peeloff operation on such asoc, moving it to another socket.

As Ben Hutchings noticed, then in such case it would return without
locking back the socket and would cause two unlocks in a row.

Further analysis also revealed that it could allow a double free if the
application managed to peeloff the asoc that is created during the
sendmsg call, because then sctp_sendmsg() would try to free the asoc
that was created only for that call.

This patch takes another approach. It will deny the peeloff operation
if there is a thread sleeping on the asoc, so this situation doesn't
exist anymore. This avoids the issues described above and also honors
the syscalls that are already being handled (it can be multiple sendmsg
calls).

Joint work with Xin Long.

Linus Torvalds f1ef09fde1 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull namespace updates from Eric Biederman:
 "There is a lot here. A lot of these changes result in subtle user
  visible differences in kernel behavior. I don't expect anything will
  care but I will revert/fix things immediately if any regressions show
  up.

  From Seth Forshee there is a continuation of the work to make the vfs
  ready for unpriviled mounts. We had thought the previous changes
  prevented the creation of files outside of s_user_ns of a filesystem,
  but it turns we missed the O_CREAT path. Ooops.

  Pavel Tikhomirov and Oleg Nesterov worked together to fix a long
  standing bug in the implemenation of PR_SET_CHILD_SUBREAPER where only
  children that are forked after the prctl are considered and not
  children forked before the prctl. The only known user of this prctl
  systemd forks all children after the prctl. So no userspace
  regressions will occur. Holding earlier forked children to the same
  rules as later forked children creates a semantic that is sane enough
  to allow checkpoing of processes that use this feature.

  There is a long delayed change by Nikolay Borisov to limit inotify
  instances inside a user namespace.

  Michael Kerrisk extends the API for files used to maniuplate
  namespaces with two new trivial ioctls to allow discovery of the
  hierachy and properties of namespaces.

  Konstantin Khlebnikov with the help of Al Viro adds code that when a
  network namespace exits purges it's sysctl entries from the dcache. As
  in some circumstances this could use a lot of memory.

  Vivek Goyal fixed a bug with stacked filesystems where the permissions
  on the wrong inode were being checked.

  I continue previous work on ptracing across exec. Allowing a file to
  be setuid across exec while being ptraced if the tracer has enough
  credentials in the user namespace, and if the process has CAP_SETUID
  in it's own namespace. Proc files for setuid or otherwise undumpable
  executables are now owned by the root in the user namespace of their
  mm. Allowing debugging of setuid applications in containers to work
  better.

  A bug I introduced with permission checking and automount is now
  fixed. The big change is to mark the mounts that the kernel initiates
  as a result of an automount. This allows the permission checks in sget
  to be safely suppressed for this kind of mount. As the permission
  check happened when the original filesystem was mounted.

  Finally a special case in the mount namespace is removed preventing
  unbounded chains in the mount hash table, and making the semantics
  simpler which benefits CRIU.

  The vfs fix along with related work in ima and evm I believe makes us
  ready to finish developing and merge fully unprivileged mounts of the
  fuse filesystem. The cleanups of the mount namespace makes discussing
  how to fix the worst case complexity of umount. The stacked filesystem
  fixes pave the way for adding multiple mappings for the filesystem
  uids so that efficient and safer containers can be implemented"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace:
  proc/sysctl: Don't grab i_lock under sysctl_lock.
  vfs: Use upper filesystem inode in bprm_fill_uid()
  proc/sysctl: prune stale dentries during unregistering
  mnt: Tuck mounts under others instead of creating shadow/side mounts.
  prctl: propagate has_child_subreaper flag to every descendant
  introduce the walk_process_tree() helper
  nsfs: Add an ioctl() to return owner UID of a userns
  fs: Better permission checking for submounts
  exit: fix the setns() && PR_SET_CHILD_SUBREAPER interaction
  vfs: open() with O_CREAT should not create inodes with unknown ids
  nsfs: Add an ioctl() to return the namespace type
  proc: Better ownership of files for non-dumpable tasks in user namespaces
  exec: Remove LSM_UNSAFE_PTRACE_CAP
  exec: Test the ptracer's saved cred to see if the tracee can gain caps
  exec: Don't reset euid and egid when the tracee has CAP_SETUID
  inotify: Convert to using per-namespace limits

Pull drm updates from Dave Airlie:
 "This is the main drm pull request for v4.11.

  Nothing too major, the tinydrm and mmu-less support should make
  writing smaller drivers easier for some of the simpler platforms, and
  there are a bunch of documentation updates.

  Intel grew displayport MST audio support which is hopefully useful to
  people, and FBC is on by default for GEN9+ (so people know where to
  look for regressions). AMDGPU has a lot of fixes that would like new
  firmware files installed for some GPUs.

  Other than that it's pretty scattered all over.

Linus Torvalds c35675f351 ARM: SoC 64-bit changes for v4.11
Changes to platform code for 64-bit ARM platforms, only trivial
 stuff this time, a few defconfig changes to enable drivers, and
 a new entry for the Cavium ThunderX2 platform.

Linus Torvalds 6ae52c65e0 ARM: SoC platform updates
In the SoC branch we normally collect classic arch/arm/mach-* contents, i.e.
 C code changes for SoC platforms. This release cycle the diffstat is quite
 nice, in that we're removing 3x the amount of code that's being added.
 
 The main reason for this is that there's a removal of camera drivers for
 Freescale i.MX chips (driver was removed so the device registration isn't
 needed any more). There's also removal of display initialization code for OMAP
 that is no longer needed.
 
 The rest are mostly minor tweaks and cleanups; constification on Samsung
 platforms, cleanup of ux500 platform data, purge of other unused platform
 data/device seutp on i.MX and other good stuff.
 
 New SoC support this cycle is for two Allwinner platforms, H2+ and V3s.

Linus Torvalds af8999f672 ARM: SoC non-urgent fixes for merge window
We sometimes collect non-critical fixes that come in during the later part
 of the merge window in a branch for the next release instead, and this is
 that contents for v4.11.
 
 Most of these are OMAP fixes, dealing with OMAP36/37 detection, quirks
 and setup. There's also some fixes for Davinci and a Kconfig fix for SCPI
 to only enable on ARM{,64}.
