Add defines for server-side extended attribute support. Most have
already been added as part of client support, but these are
the network order error codes for the noxattr and xattr2big errors,
and the addition of the xattr support to the supported file
attributes (if configured).

nfs4_decode_write has code to parse incoming XDR write data in to
a kvec head, and a list of pages.
Put this code in to a separate function, so that it can be used
later by the xattr code, for setxattr. No functional change.

Add a function that checks is an extended attribute namespace is
supported for an inode, meaning that a handler must be present
for either the whole namespace, or at least one synthetic
xattr in the namespace.
To be used by the nfs server code when being queried for extended
attributes support.

set/removexattr on an exported filesystem should break NFS delegations.
This is true in general, but also for the upcoming support for
RFC 8726 (NFSv4 extended attribute support). Make sure that they do.
Additionally, they need to grow a _locked variant, since callers might
call this with i_rwsem held (like the NFS server code).

I have a few KGDB-related fixes that I'd like to target for 5.8-rc5. They're
mostly fixes for build warnings, but there's also:
* Support for the qSupported and qXfer packets, which are necessary to pass
around GDB XML information which we need for the RISC-V GDB port to fully
function.
* Users can now select STRICT_KERNEL_RWX instead of forcing it on.
I know it's a bit late for rc5, as these are not critical it's not a big deal
if they don't make it in.

CONFIG_CC_IS_GCC is undefined when Clang is used, which breaks the build
(see our Travis link below).
Clang 8 was chosen as a minimum version for this check because there
were some improvements around __builtin_constant_p in that release. In
reality, MIPS was not even buildable until clang 9 so that check was not
technically necessary. Just remove all compiler checks and just assume
that we have a working compiler.

Fix two issues found by syzkaller.
Patch #1 removes inappropriate usage of WARN_ON() following memory
allocation failure. Constantly triggered when syzkaller injects faults.
Patch #2 fixes a use-after-free that can be triggered by 'devlink dev
info' following a failed devlink reload.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
In case devlink reload failed, it is possible to trigger a
use-after-free when querying the kernel for device info via 'devlink dev
info' [1].
This happens because as part of the reload error path the PCI command
interface is de-initialized and its mailboxes are freed. When the
devlink '->info_get()' callback is invoked the device is queried via the
command interface and the freed mailboxes are accessed.
Fix this by initializing the command interface once during probe and not
during every reload.
This is consistent with the other bus used by mlxsw (i.e., 'mlxsw_i2c')
and also allows user space to query the running firmware version (for
example) from the device after a failed reload.

net: macb: Wake-on-Lan magic packet fixes and GEM handling
Here is a split series to fix WoL magic-packet on the current macb driver. Only
fixes in this one based on current net/master.
Changes in v5:
- Addressed the error code returned by phylink_ethtool_set_wol() as suggested
by Russell.
If PHY handles WoL, MAC doesn't stay in the way.
- Removed Florian's tag on 3/5 because of the above changes.
- Correct the "Fixes" tag on 1/5.
Changes in v4:
- Pure bug fix series for 'net'. GEM addition and MACB update removed: will be
sent later.
Changes in v3:
- Revert some of the v2 changes done in macb_resume(). Now the resume function
supports in-depth re-configuration of the controller in order to deal with
deeper sleep states. Basically as it was before changes introduced by this
series
- Tested for non-regression with our deeper Power Management mode which cuts
power to the controller completely
Changes in v2:
- Add patch 4/7 ("net: macb: fix macb_suspend() by removing call to netif_carrier_off()")
needed for keeping phy state consistent
- Add patch 5/7 ("net: macb: fix call to pm_runtime in the suspend/resume functions") that prevent
putting the macb in runtime pm suspend mode when WoL is used
- Collect review tags on 3 first patches from Florian: Thanks!
- Review of macb_resume() function
- Addition of pm_wakeup_event() in both MACB and GEM WoL IRQ handlers
====================

The calls to pm_runtime_force_suspend/resume() functions are only
relevant if the device is not configured to act as a WoL wakeup source.
Add the device_may_wakeup() test before calling them.

As we now use the phylink call to phylink_stop() in the non-WoL path,
there is no need for this call to netif_carrier_off() anymore. It can
disturb the underlying phylink FSM.

Keep previous function goals and integrate phylink actions to them.
phylink_ethtool_get_wol() is not enough to figure out if Ethernet driver
supports Wake-on-Lan.
Initialization of "supported" and "wolopts" members is done in phylink
function, no need to keep them in calling function.
phylink_ethtool_set_wol() return value is considered and determines
if the MAC has to handle WoL or not. The case where the PHY doesn't
implement WoL leads to the MAC configuring it to provide this feature.

Change the way the "magic-packet" DT property is handled in the
macb_probe() function, matching DT binding documentation.
Now we mark the device as "wakeup capable" instead of calling the
device_init_wakeup() function that would enable the wakeup source.
For Ethernet WoL, enabling the wakeup_source is done by
using ethtool and associated macb_set_wol() function that
already calls device_set_wakeup_enable() for this purpose.
That would reduce power consumption by cutting more clocks if
"magic-packet" property is set but WoL is not configured by ethtool.

Use the proper struct device pointer to check if the wakeup flag
and wakeup source are positioned.
Use the one passed by function call which is equivalent to
&bp->dev->dev.parent.
It's preventing the trigger of a spurious interrupt in case the
Wake-on-Lan feature is used.

We currently account the memory after the exit work has been run, but
that leaves a gap where a process has closed its ring and until the
memory has been accounted as freed. If the memlocked ulimit is
borderline, then that can introduce spurious setup errors returning
-ENOMEM because the free work hasn't been run yet.
Account this as freed when we close the ring, as not to expose a tiny
gap where setting up a new ring can fail.
Fixes: 85faa7b834 ("io_uring: punt final io_ring_ctx wait-and-free to workqueue")
Cc: stable@vger.kernel.org # v5.7
Signed-off-by: Jens Axboe <axboe@kernel.dk>
When there is an error the caller frees "info->node" so the free here
will result in a double free. We should just delete first kfree().
