net: filter: get rid of BPF_S_* enum
This patch finally allows us to get rid of the BPF_S_* enum.
Currently, the code performs unnecessary encode and decode
workarounds in seccomp and filter migration itself when a filter
is being attached in order to overcome BPF_S_* encoding which
is not used anymore by the new interpreter resp. JIT compilers.
Keeping it around would mean that also in future we would need
to extend and maintain this enum and related encoders/decoders.
We can get rid of all that and save us these operations during
filter attaching. Naturally, also JIT compilers need to be updated
by this.
Before JIT conversion is being done, each compiler checks if A
is being loaded at startup to obtain information if it needs to
emit instructions to clear A first. Since BPF extensions are a
subset of BPF_LD | BPF_{W,H,B} | BPF_ABS variants, case statements
for extensions can be removed at that point. To ease and minimalize
code changes in the classic JITs, we have introduced bpf_anc_helper().
Tested with test_bpf on x86_64 (JIT, int), s390x (JIT, int),
arm (JIT, int), i368 (int), ppc64 (JIT, int); for sparc we
unfortunately didn't have access, but changes are analogous to
the rest.

cpumask,net: Affinity hint helper function
This patchset will set affinity hint to influence IRQs to be allocated on the
same NUMA node as the one where the card resides. As discussed in
http://www.spinics.net/lists/netdev/msg271497.html
If the number of IRQs allocated is greater than the number of local NUMA cores, all
local cores will be used first, and the rest of the IRQs will be on a remote
NUMA node.
If no NUMA support - IRQ's and cores will be mapped 1:1
Since the utility function to calculate the mapping could be useful in other mq
drivers in the kernel, it was added to cpumask.[ch]
This patchset was tested and applied on top of net-next since the first
consumer is a network device (mlx4_en). Over commit

Changes from V5:
- Moved the utility function from kernel/irq/manage.c to lib/cpumask.c, and
renamed it's name accordingly to cpumask_set_cpu_local_first()
- Added some comments as Thomas Gleixner suggested
- Changed -EINVAL to -EAGAIN, that describes the error situtation better.
Changes from V4:
- Patch 1/2: irq: Utility function to get affinity_hint by policy
Thank you Ben for the great review:
- Moved the function it kernel/irq/manage.c since it could be useful for
block mq devices
- Fixed Typo's
- Use cpumask_t * instead of cpumask_var_t in function header
- Restructured the function to remove NULL assignment in a cpumask_var_t
- Fix for offline local CPU's

net/mlx4_en: Use affinity hint
The “affinity hint” mechanism is used by the user space
daemon, irqbalancer, to indicate a preferred CPU mask for irqs.
Irqbalancer can use this hint to balance the irqs between the
cpus indicated by the mask.
We wish the HCA to preferentially map the IRQs it uses to numa cores
close to it. To accomplish this, we use cpumask_set_cpu_local_first(), that
sets the affinity hint according the following policy:
First it maps IRQs to “close” numa cores. If these are exhausted, the
remaining IRQs are mapped to “far” numa cores.

Intel Wired LAN Driver Updates
This series contains updates to i40e and i40evf.
Kevin updates the i40e and i40evf driver i40e_check_asq_alive() to ensure
the length register offset is non-zero which indicates that the software
has initialized the admin queue. Also removes PCTYPE definitions which are
now reserved.
Mitch enables descriptor prefetch for rings belonging to the virtual function.
Also configures the VF minimum transmit rate to 50 Mbps rather than 0 which was
be interpreted as no limit at all. Mitch found in order for the VF to achieve
its programmed transmit rate, we need to set the max credit value to 4.
Lastly fixes a Tx hang and firmware crash that happens after setting the MTU
on a VF by not using the RESETTING state during reinit, this is because
the RESETTING state means that a catastrophic hardware bad thing is happening
and the driver needs to tiptoe around and not use the admin queue or registers.
A reinit is no big deal and we can use the admin queue (and we should) so
do not set the state to RESETTING during reinit to resolve the bug.
Akeem changes the declaration of the transmit and receive rings inside
several loops to eliminate declaring the same ring every time for the
duration of the loop and declares them just once before the loop. Also fixes
the driver to clear the recovery pending bit if pf_reset fails instead of
falling through the setup process.
Anjali makes a change based on feedback from Ben Hutchings that cmd->data
needs to be reported in ETHTOOL_GRXCLSRLCNT and use a helper function to
calculate the total filter count.
Jesse removes storm control since the storm control features are not apart
of the hardware and were mistakenly left in the code.
Greg changes tx_lpi_status and rx_lpi_status from bool to u32 to avoid
sparse errors.
Shannon adds the clear_pxe AdminQ API call to tell the firmware that the
driver is taking over from PXE. In addition, relaxes the firmware API
check to allow more flexibility in handling newer NICs and NVMs in the field.
Vasu ensures that FCoE is disabled for MFP modes since it is not supported
by overriding the hardware FCoE capability.

Intel Wired LAN Driver Updates

Emil provides a fix for ixgbe so that non-fiber devices with MNG FW enabled
are able to link at 100Mbps.
Jacob provides several changes for ixgbe, most of which are PTP related.
Renames ixgbe_ptp_enable() to ixgbe_ptp_feature_enable() to better reflect
the functions purpose. Extracts the hardware setup logic for the PTP
hardware bits from the ixgbe_ptp_set_ts_config() to enable future work for
the ixgbe_ptp_reset(). Maintain the hwstamp configuration through a reset
and extracts the creation of the PTP clock device from ptp_init() in order
to properly handle a suspend/resume cycle and only calls it if we don't
already have a ptp_clock pointer.
David provides a patch to expend the e1000e driver to turn on unicast
PROMISC when there is failure to write to a shared receive address register.
The fix update_phy_task() for 82579 is expanded to include newer PHYs as well
so that the dev_spec->eee_lp_ability has the correct value when going into
SX states.
Todd provides a e1000e fix an errata for 82574/82583 where it is possible
bad bits are read from SYSTIMH/L so check to see that the time is
incrementing at a reasonable rate and is a multiple of the time incremental
value. Removes a redundant igb PHY power down register write.

e1000e: Failure to write SHRA turns on PROMISC mode
Previously, the check to turn on promiscuous mode only took into account
the total number of SHared Receive Address (SHRA) registers and if the
request was for a register within that range. It is possible that the
Management Engine might have locked a number of SHRA and not allowed a
new address to be written to the requested register.
Add a function to determine the number of unlocked SHRA registers. Then
determine if the number of registers available is sufficient for our needs,
if not then return -ENOMEM so that UNICAST PROMISC mode is activated.
Since the method by which ME claims SHRA registers is non-deterministic,
also add a return value to the function attempting to write an address
to a SHRA, and return a -E1000_ERR_CONFIG if the write fails. The error
will be passed up the function chain and allow the driver to also set
UNICAST PROMISC when this happens.

Resume path calls .open but suspend path cannot call .stop because

netfilter: bridge: fix Kconfig unmet dependencies
Before
f5efc69 ("netfilter: nf_tables: Add meta expression key for
bridge interface name"), the entire net/bridge/netfilter/ directory
depended on BRIDGE_NF_EBTABLES, ie. on ebtables. However, that
directory already contained the nf_tables bridge extension that
we should allow to compile separately. In
f5efc69, we tried to
generalize this by using CONFIG_BRIDGE_NETFILTER which was not a good
idea since this option already existed and it is dedicated to enable
the Netfilter bridge IP/ARP filtering.
Let's try to fix this mess by:
1) making net/bridge/netfilter/ dependent on the toplevel
CONFIG_NETFILTER option, just like we do with the net/netfilter and
net/ipv{4,6}/netfilter/ directories.
2) Changing 'selects' to 'depends on' NETFILTER_XTABLES for
BRIDGE_NF_EBTABLES. I believe this problem was already before
f5efc69:
warning: (BRIDGE_NF_EBTABLES) selects NETFILTER_XTABLES which has
unmet direct dependencies (NET && INET && NETFILTER)
3) Fix ebtables/nf_tables bridge dependencies by making NF_TABLES_BRIDGE
and BRIDGE_NF_EBTABLES dependent on BRIDGE and NETFILTER:

BRIDGE_NETFILTER which has unmet direct dependencies (NET && BRIDGE &&

net: filter: improve test case framework
This patch simplifies and refactors the test case code a
bit and also adds a summary of all test that passed or
failed in the kernel log, so that it's easier to spot if
something has failed.
Future work could further extend the test framework to also
support different input 'stimuli' i.e. related structures
to seccomp.
