commit 517d7c79 ("tipc: fix hanging poll() for stream sockets")
introduced a regression for clients using non-blocking sockets.
After the commit, we send EPOLLOUT event to the client even in
TIPC_CONNECTING state. This causes the subsequent send() to fail
with ENOTCONN, as the socket is still not in TIPC_ESTABLISHED state.

In this commit, we:
- improve the fix for hanging poll() by replacing sk_data_ready()
  with sk_state_change() to wake up all clients.
- revert the faulty updates introduced by commit 517d7c79
  ("tipc: fix hanging poll() for stream sockets").

When a queue(tfile) is detached through __tun_detach(), we move the
last enabled tfile to the position where detached one sit but don't
NULL out last position. We expect to synchronize the datapath through
tun->numqueues. Unfortunately, this won't work since we're lacking
sufficient mechanism to order or synchronize the access to
tun->numqueues.

To fix this, NULL out the last position during detaching and check
RCU protected tfile against NULL instead of checking tun->numqueues in
datapath.

====================
net: phy: realtek: Fix RGMII TX/RX-delays initial config of rtl8211(e|f)

It has been discovered that RX/TX delays of rtl8211e ethernet PHY
can be configured via a MDIO register hidden in the extension pages
layout. Particularly the extension page 0xa4 provides a register 0x1c,
which bits 1 and 2 control the described delays. They are used to
implement the "rgmii-{id,rxid,txid}" phy-mode support in patch 1.

The second patch makes sure the rtl8211f TX-delay is configured only
if RGMII interface mode is specified including the rgmii-rxid one.
In other cases (most importantly for NA mode) the delays are supposed
to be preconfigured by some other software or hardware and should be
left as is without any modification. The similar thing is also done
for rtl8211e in the patch 1 of this series.

Changelog v3
- Add this cover-letter.
- Add Andrew' Reviewed-by tag to patch 1.
- Accept RGMII_RXID interface mode for rtl8211f and clear the TX_DELAY
  bit in this case.
- Initialize ret variable with 0 to prevent the "may be used uninitialized"
  warning in patch 1.

Changelog v4
- Rebase onto net-next

It's prone to problems if delay is cleared out for other than RGMII
modes. So lets set/clear the TX-delay in the config register only
if actually RGMII-like interface mode is requested. This only
concerns rtl8211f chips.

There are two chip pins named TXDLY and RXDLY which actually adds the 2ns
delays to TXC and RXC for TXD/RXD latching. Alas this is the only
documented info regarding the RGMII timing control configurations the PHY
provides. It turns out the same settings can be setup via MDIO registers
hidden in the extension pages layout. Particularly the extension page 0xa4
provides a register 0x1c, which bits 1 and 2 control the described delays.
They are used to implement the "rgmii-{id,rxid,txid}" phy-mode.

The hidden RGMII configs register utilization was found in the rtl8211e
U-boot driver:
https://elixir.bootlin.com/u-boot/v2019.01/source/drivers/net/phy/realtek.c#L99

There is also a freebsd-folks discussion regarding this register:
https://reviews.freebsd.org/D13591

It confirms that the register bits field must control the so called
configuration pins described in the table 12-13 of the official PHY
datasheet:
8:6 = PHY Address
5:4 = Auto-Negotiation
3 = Interface Mode Select
2 = RX Delay
1 = TX Delay
0 = SELRGV

The while-loop exit condition check is not correct; the
loop should continue if the returns from the function calls are
negative or the CRC status returns are invalid.  Currently it
is ignoring the returns from the function calls.  Fix this by
removing the status return checks and only break from the loop
at the very end when we know that all the success condtions have
been met.

Kudos to Dan Carpenter for describing the correct fix and
Vladimir Oltean for noting the change to the check on the number
of retries.

     through AFS.

     This required emulation of fine-grained locking when the server
     will only support whole-file locks and no upgrade/downgrade. Four
     modes are provided, settable by mount parameter:

       "flock=local"   - No reference to the server

       "flock=openafs" - Fine-grained locks are local-only, whole-file
                         locks require sufficient server locks

       "flock=strict"  - All locks require sufficient server locks

       "flock=write"   - Always get an exclusive server lock

     If the volume is a read-only or backup volume, then flock=local for
     that volume.

   - Log extra information for a couple of cases where the client mucks
     up somehow: AFS vnode with undefined type and dir check failure -
     in both cases we seem to end up with unfilled data, but the issues
     happen infrequently and are difficult to reproduce at will.

   - Implement silly rename for unlink() and rename().

   - Set i_blocks so that du can get some information about usage.

   - Fix xattr handlers to return the right amount of data and to not
     overflow buffers.

Pull misc dcache updates from Al Viro:
 "Most of this pile is putting name length into struct name_snapshot and
  making use of it.

  The beginning of this series ("ovl_lookup_real_one(): don't bother
  with strlen()") ought to have been split in two (separate switch of
  name_snapshot to struct qstr from overlayfs reaping the trivial
  benefits of that), but I wanted to avoid a rebase - by the time I'd
  spotted that it was (a) in -next and (b) close to 5.1-final ;-/"

Pull audit updates from Paul Moore:
 "We've got a reasonably broad set of audit patches for the v5.2 merge
  window, the highlights are below:

   - The biggest change, and the source of all the arch/* changes, is
     the patchset from Dmitry to help enable some of the work he is
     doing around PTRACE_GET_SYSCALL_INFO.

     To be honest, including this in the audit tree is a bit of a
     stretch, but it does help move audit a little further along towards
     proper syscall auditing for all arches, and everyone else seemed to
     agree that audit was a "good" spot for this to land (or maybe they
     just didn't want to merge it? dunno.).

   - We can now audit time/NTP adjustments.

   - We continue the work to connect associated audit records into a
     single event"

Pull selinux updates from Paul Moore:
 "We've got a few SELinux patches for the v5.2 merge window, the
  highlights are below:

   - Add LSM hooks, and the SELinux implementation, for proper labeling
     of kernfs. While we are only including the SELinux implementation
     here, the rest of the LSM folks have given the hooks a thumbs-up.

   - Update the SELinux mdp (Make Dummy Policy) script to actually work
     on a modern system.

   - Disallow userspace to change the LSM credentials via
     /proc/self/attr when the task's credentials are already overridden.

     The change was made in procfs because all the LSM folks agreed this
     was the Right Thing To Do and duplicating it across each LSM was
     going to be annoying"
