The reason of including <linux/bitops.h> here is just for BIT() macro.
Since commit 8bd9cb51daac8 ("locking/atomics, asm-generic: Move some
macros from <linux/bitops.h> to a new <linux/bits.h> file"),
<linux/bits.h> is enough for such compile-time macros.

In order to upload helper module automatically, helper alias name
is needed. so that MODULE_ALIAS_NFCT_HELPER() should be added.
And unlike other nat helper modules, the nf_nat_snmp_basic can be
used independently.
helper name is "snmp_trap" so that alias name will be
"nfct-helper-snmp_trap" by MODULE_ALIAS_NFCT_HELPER(snmp_trap)
test command:
%iptables -t raw -I PREROUTING -p udp -j CT --helper snmp_trap
%lsmod | grep nf_nat_snmp_basic
We can see nf_nat_snmp_basic module is uploaded automatically.

Eyal says:
doesn't the use of nft_pf(pkt) in this context limit the matching of
encapsulated packets to the same family?
IIUC when an e.g. IPv6-in-IPv4 packet is matched, the nft_pf(pkt) will
be the decapsulated packet family - IPv6 - whereas the state may be
IPv4. So this check would not allow matching the 'underlay' address in
such cases.
I know this was a limitation in xt_policy. but is this intentional in
this matcher? or is it possible to use state->props.family when
validating the match instead of nft_pf(pkt)?
Userspace already tells us which address family it expects to match, so
we can just use the real state family rather than the hook family.
so change it as suggested above.

We want to set the irq parent for interrupts that we're setting up to be
cascaded from another interrupt controller, but we may or may not have
already mapped the gpiochip irqs into the kernel's virtual irq number
space at this point. If we have mapped irqs before calling here, then
we've gone through gpiochip_irq_map() and called irq_set_parent()
already. If we haven't mapped irqs, then the gpiochip is dynamically
mapping irqs and we can rely on gpiochip_irq_map() or the gpio driver's
irqdomain ops to setup the irq parent properly.
Either way, setting the parent here when cascading the gpiochip doesn't
make much sense because it should be done at irq mapping time. In the
dynamic mapping case, this code is mapping virq 0 to some parent virq in
a loop. While that's benign, let's drop this code to simplify.

net: Kernel side filtering for route dumps
Implement kernel side filtering of route dumps by protocol (e.g., which
routing daemon installed the route), route type (e.g., unicast), table
id and nexthop device.
iproute2 has been doing this filtering in userspace for years; pushing
the filters to the kernel side reduces the amount of data the kernel
sends and reduces wasted cycles on both sides processing unwanted data.
These initial options provide a huge improvement for efficiently
examining routes on large scale systems.
v2
- better handling of requests for a specific table. Rather than walking
the hash of all tables, lookup the specific table and dump it
- refactor mr_rtm_dumproute moving the loop over the table into a
helper that can be invoked directly
- add hook to return NLM_F_DUMP_FILTERED in DONE message to ensure
it is returned even when the dump returns nothing

Update parsing of route dump request to enable kernel side filtering.
Allow filtering results by protocol (e.g., which routing daemon installed
the route), route type (e.g., unicast), table id and nexthop device. These
amount to the low hanging fruit, yet a huge improvement, for dumping
routes.
ip_valid_fib_dump_req is called with RTNL held, so __dev_get_by_index can
be used to look up the device index without taking a reference. From
there filter->dev is only used during dump loops with the lock still held.
Set NLM_F_DUMP_FILTERED in the answer_flags so the user knows the results
have been filtered should no entries be returned.

With dump filtering we need a way to ensure the NLM_F_DUMP_FILTERED
flag is set on a message back to the user if the data returned is
influenced by some input attributes. Normally this can be done as
messages are added to the skb, but if the filter results in no data
being returned, the user could be confused as to why.
This patch adds answer_flags to the netlink_callback allowing dump
handlers to set the NLM_F_DUMP_FILTERED at a minimum in the
NLMSG_DONE message ensuring the flag gets back to the user.
The netlink_callback space is initialized to 0 via a memset in
__netlink_dump_start, so init of the new answer_flags is covered.

A user can provide a hint which will be attached to the packet and written
to the CQE on receive. This can be used as a way to offload operations
into the HW, for example parsing a packet which is a tunneled packet, and
if so, pass 0x1 as the hint. The software can use that hint to decapsulate
the packet and parse only the inner headers thus saving CPU cycles.

pull-request: bpf-next 2018-10-16
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Convert BPF sockmap and kTLS to both use a new sk_msg API and enable
sk_msg BPF integration for the latter, from Daniel and John.
2) Enable BPF syscall side to indicate for maps that they do not support
a map lookup operation as opposed to just missing key, from Prashant.
3) Add bpftool map create command which after map creation pins the
map into bpf fs for further processing, from Jakub.
4) Add bpftool support for attaching programs to maps allowing sock_map
and sock_hash to be used from bpftool, from John.
5) Improve syscall BPF map update/delete path for map-in-map types to
wait a RCU grace period for pending references to complete, from Daniel.
6) Couple of follow-up fixes for the BPF socket lookup to get it
enabled also when IPv6 is compiled as a module, from Joe.
7) Fix a generic-XDP bug to handle the case when the Ethernet header
was mangled and thus update skb's protocol and data, from Jesper.
8) Add a missing BTF header length check between header copies from
user space, from Wenwen.
9) Minor fixups in libbpf to use __u32 instead u32 types and include
proper perf_event.h uapi header instead of perf internal one, from Yonghong.
10) Allow to pass user-defined flags through EXTRA_CFLAGS and EXTRA_LDFLAGS
to bpftool's build, from Jiri.
11) BPF kselftest tweaks to add LWTUNNEL to config fragment and to install
with_addr.sh script from flow dissector selftest, from Anders.

setup_irq(LOONGSON_HT1_IRQ, &cascade_irqaction);
This is because both chained_action and cascade_irqaction don't have
IRQF_SHARED flag. This will cause Loongson-3 resume fails because HPET
timer interrupt can't be delivered during S3. So we set the irqchip of

Masking/unmasking the CPU UART irq in CP0_Status (and redirecting it to
other CPUs) may cause interrupts be lost, especially in multi-package
machines (Package-0's UART irq cannot be delivered to others). So make
mask_loongson_irq() and unmask_loongson_irq() be no-ops.
The original problem (UART IRQ may deliver to any core) is also because
of masking/unmasking the CPU UART irq in CP0_Status. So it is safe to
remove all of the stuff.

appear to be arrays of pointers to strings. It is unused throughout the
kernel tree, so delete the dead code.

asm/asm.h contains CPRESTORE, CPADD & CPLOAD macros that are intended
for use with position independent code, but are not used anywhere in the
kernel - along with a comment to that effect. Remove the dead code.

We have macros in asm/asm.h to allow for use of the MOVN & MOVZ
instructions with compare-and-branch sequences providing compatibility
for ISA versions which don't include those instructions. However the
macros are unused, and appear to have always been unused. Delete the
dead code.
