Jump is now the only one using value action opcode. This is going to
change soon. So introduce helpers to work with this. Convert TC_ACT_JUMP.
This also fixes the TC_ACT_JUMP check, which is incorrectly done as a
bit check, not a value check.
Fixes: e0ee84ded796 ("net sched actions: Complete the JUMPX opcode")

PTP hardware filter configuration performed by the driver for a given
user requested config is not correct for some of the PTP modes.
Following changes are needed for PTP config-filter implementation.
1. NIG_REG_TX_PTP_EN register - Bits 0/1/2 respectively enables
TimeSync/"V1 frame format support"/"V2 frame format support" on
the TX side. Set the associated bits based on the user request.
2. ptp4l application fails to operate in Peer Delay mode. Following
changes are needed to fix this,
a. Driver should enable (set to 0) DA #1-related bits for IPv4,
IPv6 and MAC destination addresses in these registers:
NIG_REG_TX_LLH_PTP_RULE_MASK
NIG_REG_LLH_PTP_RULE_MASK
b. NIG_REG_LLH_PTP_PARAM_MASK/NIG_REG_TX_LLH_PTP_PARAM_MASK should
be set to 0x0 in all modes.

The IOT2000 is industrial controller platform, derived from the Intel
Galileo Gen2 board. The variant IOT2020 comes with one LAN port, the
IOT2040 has two of them. They can be told apart based on the board asset

When the instruction right before the branch destination is
a 64 bit load immediate, we currently calculate the wrong
jump offset in the ctx->offset[] array as we only account
one instruction slot for the 64 bit load immediate although
it uses two BPF instructions. Fix it up by setting the offset
into the right slot after we incremented the index.

This work adds BPF_XADD for BPF_W/BPF_DW to the arm64 JIT and therefore
completes JITing of all BPF instructions, meaning we can thus also remove
the 'notyet' label and do not need to fall back to the interpreter when
BPF_XADD is used in a program!
This now also brings arm64 JIT in line with x86_64, s390x, ppc64, sparc64,
where all current eBPF features are supported.
BPF_W example from test_bpf:
.u.insns_int = {
BPF_ALU32_IMM(BPF_MOV, R0, 0x12),
BPF_ST_MEM(BPF_W, R10, -40, 0x10),
BPF_STX_XADD(BPF_W, R10, R0, -40),

Fix some bpf program testing framework bugs
This series fixes two issue:
1) Accidental user pointer dereference in bpf_test_finish()
2) The packet data given to the test programs is not aligned correctly
The first issue is fixed simply because we have a kernel side copy
of the datastructure in question already. And the second bug is
a simple matter of applying NET_IP_ALIGN where needed.

The audit subsystem implemented its own buffer cache mechanism which
is a bit silly these days when we could use the kmem_cache construct.
Some credit is due to Florian Westphal for originally proposing that
we remove the audit cache implementation in favor of simple
kmalloc()/kfree() calls, but I would rather have a dedicated slab
cache to ease debugging and future stats/performance work.

struct timespec is not y2038 safe.
Audit timestamps are recorded in string format into
an audit buffer for a given context.
These mark the entry timestamps for the syscalls.
Use y2038 safe struct timespec64 to represent the times.
The log strings can handle this transition as strings can
hold upto 1024 characters.

Eliminate flipping in and out of message fields, dropping fields in the
process.
Sample raw message format IPv4 UDP:

Sample raw message format IPv6 ICMP6:
type=NETFILTER_PKT msg=audit(1487874761.381:227): mark=0x223894b7 saddr=::1 daddr=::1 proto=58^]

When a sysadmin wishes to monitor module unloading with a syscall rule such as:
-a always,exit -F arch=x86_64 -S delete_module -F key=mod-unload
the SYSCALL record doesn't tell us what module was requested for unloading.
Use the new KERN_MODULE auxiliary record to record it.
The SYSCALL record result code will list the return code.

"The main x86 MM changes in this cycle were:
- continued native kernel PCID support preparation patches to the TLB
flushing code (Andy Lutomirski)
- various fixes related to 32-bit compat syscall returning address
over 4Gb in applications, launched from 64-bit binaries - motivated
by C/R frameworks such as Virtuozzo. (Dmitry Safonov)
- continued Intel 5-level paging enablement: in particular the
conversion of x86 GUP to the generic GUP code. (Kirill A. Shutemov)
- x86/mpx ABI corner case fixes/enhancements (Joerg Roedel)
