Remove M_PKTHDR from secondary mbufs when reassembling packets.

This is a real problem, because I found at least one component that relies
on the fact that only the first mbuf has M_PKTHDR: far from here, in
m_splithdr, we don't update m->m_pkthdr.len if M_PKTHDR is found in a
secondary mbuf. (The initial intention there was to avoid updating
m_pkthdr.len twice, the assumption was that if M_PKTHDR is set then we're
dealing with the first mbuf.) Therefore, when handling fragmented IPsec
packets (in particular IPv6, IPv4 is a bit more complicated), we may end
up with an incorrect m_pkthdr.len after authentication or decryption. In
the case of ESP, this can lead to a remote crash on this instruction:

m_copydata(m, m->m_pkthdr.len - 3, 3, lastthree);

m_pkthdr.len is bigger than the actual mbuf chain.

It seems possible to me to trigger this bug even if you don't have the ESP
key, because the fragmentation part is outside of the encrypted ESP
payload.

So if you MITM the target, and intercept an incoming ESP packet (which you
can't decrypt), you should be able to forge a new specially-crafted,
fragmented packet and stuff the ESP payload (still encrypted, as you
intercepted it) into it. The decryption succeeds and the target crashes.

Fix another poll mode assumption breaking. Implemented by msaitoh@n.o, I just commit by proxy.
ixgbe_rearm_queues() writes EICS register(s). 82599, X540 and X550
specifications say "Following a write of 1b to any bit in the EICS register
(interrupt cause set), its corresponding bit in the EIMS register is auto
set as well enabling its interrupt." in "Extended Interrupt Auto Mask Enable
(EIAM) Register" section. That is, ixgbe_rearm_queues() causes interrupts
regardless of the status managed by ixgbe_enable_queue()/ixgbe_disable_queue().

That can break poll mode assumption.

In fact, the problem occurs in the following situation
    - CPU#A has high load traffic, in contrast, CPU#B has not so high load traffic
    - CPU#A is occurred interrupt by its NIC queue
      - CPU#A calls ixgbe_disable_queue() in interrupt handler(ixgbe_msix_que())
      - CPU#A kick softint handler(ixgbe_handle_que())
        - CPU#A begins softint
        - CPU#A's NIC queue is set que->txr->busy flag
        - With some reason, CPU#A can do ixg interrupt handler
          E.g. when one of CPU#A's softnet handlers sleeps, ipl is lowered
    - CPU#B starts callout
      - CPU#B calls ixgbe_local_timer1()
        - CPU#B writes EICS bit corresponding CPU#A's NIC queue bit
    - CPU#A's NIC queue causes interrupt whie CPU#A is running in poll mode
      - CPU#A calls ixgbe_disable_queue() in interrupt handler *again*
    - CPU#A has done polling, and then CPU#A calls ixgbe_enable_queue() *once*
    - CPU#A's NIC queue interrupt is disabled until ixg is detached as
      ixgbe_disable_queue() is called twice though ixgbe_disable_queue() is
      called once only
NOTE:
82598 does not say so, but it is treated in the same way because of no harm.
By the way, we will refactor ixgbe_local_timer(watchdog processing) later.

Fix a race condition on DAD destructions (again)

The previous fix to DAD timers was wrong; it avoided a use-after-free but
instead introduced a memory leak.  The destruction method had delegated
a destruction of a DAD timer to the timer itself and told that by setting NULL
to dp->dad_ifa.  However, the previous fix made DAD timers do nothing on
the sign.

Fixing the issue with using callout_stop isn't easy.  One approach is to have
a refcount on dp but it introduces extra complexity that we want to avoid.

The new fix falls back to using callout_halt, which was abandoned because of
softnet_lock.  Fortunately now the network stack is protected by KERNEL_LOCK
so we can remove softnet_lock from DAD timers (callout) and use callout_halt
safely.

ATF: Reenable attach2 in t_ptrace_wait*

The primary race specific to this test has been fixed in previous commit
(wrong WNOHANG).

This test is still racy and breaks like once every 30,000 execution.
This is down like from once from every 100th execution in the past.

The remaning race is not specific to attach2 and I can reproduce it with
at least attach1. It still looks like being specific to NetBSD and it's
not reproducible on Linux and FreeBSD. Perhaps a bug with pipe(2)/write(2)/
read(2) or close to these features.

Add hw.ixvM.q[01].{interrupt_rate,[tr]xd_head,[tr]xd_tail} sysctls as ixg(4).

ixg(4) supports workqueue poll mode, but not enabled by default yet. (that is, the default behavior is *not* changed)

At the time of high load near the wire rate, the turnaround time
of update/delete processing such as "ifconfig ixg0 inet XXX" or
"ifconfig ixg0 delete" is very long. The main reason is CPU
starvation caused by ixg(4)'s softint poll mode. ixg(4) uses
workqueue poll mode instead of softint poll mode, so that this
problem will be fix.

This change may cause performance issues, so it is not enabled
by default yet. Although there are that issues, if you want to use
workqueue poll mode, do "sysctl -w hw.ixgXX.txrx_workqueue=1" while
there is no traffic on the ixgXX.

sys/dev/pci/if_wm.c: revision 1.565-1.566

- Fix a bug that wm_pll_workaround_i210() is not called on some cases.
  As I wrote in if_wm.c rev 1.329's commit message, There are three cases:
    a) Chip is I211
    b) Chip is I210 and it uses INVM (not FLASH)
    c) Chip is I210 (it uses FLASH) and NVM image version < 3.25
  Before this commit, the workaround function was not called on a) and b).

- Rename function.

Do wm_reset_mdicnfg_82580() on 82580 only.

nd6: add a nonce to DaD probes in-case they are looped back to us

This implements RFC 7527, based a similar change in FreeBSD.

Move necessary routines out of compat_util.c and into exec_elf.c

Once again, compat_util.c is only for modules, so move it back into
compat/common/files.common and out of kern/files.kern

compat_util.c is included in all kernels, so does not need to be
listed here.

doc/CHANGES{,.prev}: revision 1.138
sys/sys/ptrace.h: revision 1.63
lib/libc/sys/ptrace.2: revision 1.68
sys/kern/sys_ptrace_common.c: revision 1.35 (via patch)
tests/lib/libc/sys/t_ptrace_wait.c: revision 1.23

Remove PT_GET_SIGMASK / PT_SET_SIGMASK

These operations cloned Linux's specific PTRACE_GETSIGMASK /
PTRACE_SETSIGMASK.

This feature was useful in applications like rr/criu/reptyr-like, where
the ptrace(2) interface is abused for the purpose of constructing an
arbitrary
process. It's not reliable and not portable. For the NetBSD case it will =
be
better to invent something dedicated for serializing and deserializing a
process with threads.

Routine emulexec() in kern_exec.c needs emul_find_root().  Since
kern_exec.c is included in every kernel, so compat_util.c needs to
be included, too.

sys/netipsec/ipsec_input.c: revision 1.57
sys/netipsec/ipsec_input.c: revision 1.58

Extend these #ifdef notyet. The m_copydata's in these branches are wrong,
we are not guaranteed to have enough room for another struct ip, and we
may crash here. Triggerable remotely, but after authentication, by sending
an AH packet that has a one-byte-sized IPIP payload.

Argh, in my previous commit in this file I forgot to fix the IPv6
entry point; apply the same fix there.

Use pool(9) for llentry allocations

llentry is easy to be leaked and pool suits for it because pool is usable to
detect leaks.

Also sweep unnecessary wrappers for llentry, in_llentry and in6_llentry.

Fix memory leaks on arp -d and ndp -d for static entries

We have to delete entries on in_lltable_delete and in6_lltable_delete
unconditionally.  Note that we don't need to worry about LLE_IFADDR because
there is no such entries now.

(ozaki-r)

Fix reference leaks of llentry

callout_reset and callout_halt can cancel a pending callout without telling us.
Detect a cancel and remove a reference by using callout_pending and
callout_stop (it's a bit tricy though, we can detect it).

While here, we can remove remaining abuses of mutex_owned for softnet_lock.

(ozaki-r)

Add assertions

We must not destroy llentries holding mbufs.

Tweak sanity checks

Scheduling a timer of static entries is wrong.
