The commit 83ada39bb79d ("net: factor out a helper to decrement the
skb refcount") provided and used a helper for decrementing skb usage,
but I missed at least a spot for it.
This change remove some more duplicated code reusing skb_unref() in
napi_consume_skb(), too. The helper uses an additional, unneeded
unlikely(!skb) test - napi_consume_skb() already check it a few lines
above - but the compiler is smart enough to optimize the duplicated
test out.

There are two problems:
1) In MIPS the __NR_* macros expand to an expression, this causes the
sections of the object file to be named like:
.
.
.
[ 5] kprobe/(5000 + 1) PROGBITS 0000000000000000 000160 ...
[ 6] kprobe/(5000 + 0) PROGBITS 0000000000000000 000258 ...
[ 7] kprobe/(5000 + 9) PROGBITS 0000000000000000 000348 ...
.
.
.
The fix here is to use the "asm_offsets" trick to evaluate the macros
in the C compiler and generate a header file with a usable form of the
macros.
2) MIPS syscall numbers start at 5000, so we need a bigger map to hold
the sub-programs.

On MIPS, conditional branches can only span 32k instructions. To
exceed this limit in the JIT with the BPF maximum of 4k insns, we need
to choose eBPF insns that expand to more than 8 machine instructions.
Use BPF_LD_ABS as it is quite complex. This forces the JIT to invert
the sense of the branch to branch around a long jump to the end.
This (somewhat) verifies that the branch inversion logic and target
address calculation of the long jumps are done correctly.

Currently, verifier will reject a program if it contains an
narrower load from the bpf context structure. For example,
__u8 h = __sk_buff->hash, or
__u16 p = __sk_buff->protocol
__u32 sample_period = bpf_perf_event_data->sample_period
which are narrower loads of 4-byte or 8-byte field.
This patch solves the issue by:
. Introduce a new parameter ctx_field_size to carry the
field size of narrower load from prog type
specific *__is_valid_access validator back to verifier.
. The non-zero ctx_field_size for a memory access indicates
(1). underlying prog type specific convert_ctx_accesses
supporting non-whole-field access
(2). the current insn is a narrower or whole field access.
. In verifier, for such loads where load memory size is
less than ctx_field_size, verifier transforms it
to a full field load followed by proper masking.
. Currently, __sk_buff and bpf_perf_event_data->sample_period
are supporting narrowing loads.
. Narrower stores are still not allowed as typical ctx stores
are just normal stores.
Because of this change, some tests in verifier will fail and
these tests are removed. As a bonus, rename some out of bound
__sk_buff->cb access to proper field name and remove two
redundant "skb cb oob" tests.

10GbE Intel Wired LAN Driver Updates 2017-06-13
This series contains updates to ixgbe and ixgbevf only.
Jake completes his fix ups for our drivers with the ixgbe changes to
resolve a race condition in processing timestamp requests. These fixes
are the same fixes Jake applied earlier to the other drivers, including
the added statistic to help administrators know when an application
timestamp request is ignored.
With all the recent ixgbe/ixgbevf changes and fixes, Tony bumps the

analysis warning by changing a variable to unsigned integer since the
value can never be negative.
Emil fixes an issue for X550 devices where the qde parameter was being
ignored, so PFQDE.HIDE_VLAN was not being set.
Jeff Mahoney from SuSE fixes a possible kernel crash, where there was
a small window where tasks writing to the sriov_numvfs sysfs attribute
can sneak in after we call register_netdev(). So we need to call

The ixgbe driver has logic to handle only one Tx timestamp at a time,
using a state bit lock to avoid multiple requests at once.
It may be possible, if incredibly unlikely, that a Tx timestamp event is
requested but never completes. Since we use an interrupt scheme to
determine when the Tx timestamp occurred we would never clear the state
bit in this case.
Add an ixgbe_ptp_tx_hang() function similar to the already existing
ixgbe_ptp_rx_hang() function. This function runs in the watchdog routine
and makes sure we eventually recover from this case instead of
permanently disabling Tx timestamps.
Note: there is no currently known way to cause this without hacking the
driver code to force it.

The ixgbe driver uses a state bit lock to avoid handling more than one Tx
timestamp request at once. This is required because hardware is limited
to a single set of registers for Tx timestamps.
The state bit lock is not properly cleaned up during
ixgbe_xmit_frame_ring() if the transmit fails such as due to DMA or TSO
failure. In some hardware this results in blocking timestamps until the
service task times out. In other hardware this results in a permanent
lock of the timestamp bit because we never receive an interrupt
indicating the timestamp occurred, since indeed the packet was never
transmitted.
Fix this by checking for DMA and TSO errors in ixgbe_xmit_frame_ring() and
properly cleaning up after ourselves when these occur.

Hardware related to the ixgbe driver is limited to handling a single Tx
timestamp request at a time. Thus, the driver ignores requests for Tx
timestamp while waiting for the current request to finish. It uses
a state bit lock which enforces that only one timestamp request is
honored at a time.
Unfortunately this suffers from a simple race condition. The bit lock is
not cleared until after skb_tstamp_tx() is called notifying applications
of a new Tx timestamp. Even a well behaved application sending only one
packet at a time and waiting for a response can wake up and send a new
packet before the bit lock is cleared. This results in needlessly
dropping some Tx timestamp requests.
We can fix this by unlocking the state bit as soon as we read the
Timestamp register, as this is the first point at which it is safe to
unlock.
To avoid issues with the skb pointer, we'll use a copy of the pointer
and set the global variable in the driver structure to NULL first. This
ensures that the next timestamp request does not modify our local copy
of the skb pointer.
This ensures that well behaved applications do not accidentally race
with the unlock bit. Obviously an application which sends multiple Tx
timestamp requests at once will still only timestamp one packet at
a time. Unfortunately there is nothing we can do about this.

net: dsa: Multi-CPU ground work (v4)
This patch series prepares the ground for adding mutliple CPU port support to
DSA, and starts by removing redundant pieces of information such as
master_netdev which is cpu_dp->ethernet. Finally drivers are moved away from
directly accessing ds->dst->cpu_dp and use appropriate helper functions.
Note that if you have Device Tree blobs/platform configurations that are
currently listing multiple CPU ports, the proposed behavior in
dsa_ds_get_cpu_dp() will be to return the last bit set in ds->cpu_port_mask.
Future plans include:
- making dst->cpu_dp a flexible data structure (array, list, you name it)
- having the ability for drivers to return a default/preferred CPU port (if
necessary)
Changes in v4:
- fixed build warning with NETPOLL enabled
Changes in v3:
- removed the last patch since it causes problems with bcm_sf2/b53 in a
dual-CPU case (root cause known, proper fix underway)
- removed dsa_ds_get_cpu_dp()
Changes in v2:
- added Reviewed-by tags
- assign port->cpu_dp earlier before ops->setup() has run

* Avi fixes some fallout from my mac80211 RX flags changes
* Emmanuel fixes an issue with adhering to the spec, and
an oversight in the SMPS management code
* Jason's patch makes mac80211 use constant-time memory
comparisons for message authentication, to avoid having
potentially observable timing differences
* my fix makes mac80211 set the basic rates bitmap before
the channel so the next update to the driver has more
consistent data - this required another rework patch to
remove some useless 5/10 MHz code that can never be hit

After commit 90eff9096c ("net: phy: Allow splitting MDIO
bus/device support from PHYs") we could create a configuration where
MDIO_DEVICE=y and PHYLIB=m which leads to the following undefined

====================
MDIO bus reset GPIO cleanups
Commit 4c5e7a2c05 ("dt-bindings: mdio: Clarify binding document")
declared that a MDIO reset GPIO property should have only a single GPIO
reference/specifier, however the supporting code was left intact...
Here's a couple of the obvious cleanups to that code:
[1/2] mdio_bus: handle only single PHY reset GPIO
[2/2] mdio_bus: use devm_gpiod_get_optional()
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The MDIO reset GPIO is really a classical optional GPIO property case,
so devm_gpiod_get_optional() should have been used, not devm_gpiod_get().
Doing this saves several LoCs...
