When blocking an address, the blacklist-helper script
needs to do the following things for the ipfw packet
filter:
- create a table to hold the addresses to be blocked,
so lookups can be done quickly, and place the address
to be blocked in that table
- create rule that does the lookup in the table and
blocks the packet
The ipfw system allows multiple rules to be inserted for
a given rule number. There only needs to be one rule
to do the lookup per port. Modify the script to probe
for the existence of the rule before attempting to create
it, so only one rule is inserted, rather than one rule per
blocked address.

Previously we would truncate tm.tm_year for any time_t corresponding to
a year that does not fit in int. This issue was discovered because it
caused the bash-static build to fail when linking with LLD.
As reported by Rafael Espíndola:
Configure has
AC_FUNC_MKTIME
which expands to a test of mktime that fails with the freebsd
implementation. Given that, bash compiles a mktime.o file that
defines just mktime and uses localtime. That goes in a .a file
that is before libc.
The freebsd libc defines mktime in localtime.o, which also defines
localtime among other functions.
When lld sees an undefined reference to mktime from libc, it uses
the bash provided one and then tries to find a definition of
localtime. It is found on libc's localtime.o, but now we have a
duplicated error.
The reason it works with bfd is that bash doesn't use mktime
directly and the undefined reference from libc is resolved to the
libc implementation. It would also fail to link if bash itself
directly used mktime.
The bash-static configure test verifies that, for many values of t, either
localtime(t) returns NULL or mktime(localtime(t)) == t. This test failed
when localtime returned a truncated tm_year.
This was fixed in tzcode in 2004 but has persisted in our tree since
rS2708.

The primary end-goal of this drop is ease future merges with NetBSD and
collaborate further with the NetBSD project.
The goal was (largely, not completely as some items are still oustanding
in the NetBSD GNATS system) achieved by doing the following:
- Pushing as many changes required to port contrib/netbsd-tests
back to NetBSD as possible, then pull the upstream applied changes
back in to FreeBSD.
- Diff reduce with upstream where possible by:
-- Improving libnetbsd header, etc compat glue.
-- Using _SED variables to modify test scripts on the fly for items
that could not be upstreamed to NetBSD.
As a bonus for this work, this change also introduces testcases for

Small summary
-------------
o Almost all IPsec releated code was moved into sys/netipsec.
o New kernel modules added: ipsec.ko and tcpmd5.ko. New kernel
option IPSEC_SUPPORT added. It enables support for loading
and unloading of ipsec.ko and tcpmd5.ko kernel modules.
o IPSEC_NAT_T option was removed. Now NAT-T support is enabled by
default. The UDP_ENCAP_ESPINUDP_NON_IKE encapsulation type
support was removed. Added TCP/UDP checksum handling for
inbound packets that were decapsulated by transport mode SAs.
setkey(8) modified to show run-time NAT-T configuration of SA.
o New network pseudo interface if_ipsec(4) added. For now it is
build as part of ipsec.ko module (or with IPSEC kernel).
It implements IPsec virtual tunnels to create route-based VPNs.
o The network stack now invokes IPsec functions using special
methods. The only one header file <netipsec/ipsec_support.h>
should be included to declare all the needed things to work
with IPsec.
o All IPsec protocols handlers (ESP/AH/IPCOMP protosw) were removed.
Now these protocols are handled directly via IPsec methods.
o TCP_SIGNATURE support was reworked to be more close to RFC.
o PF_KEY SADB was reworked:
- now all security associations stored in the single SPI namespace,
and all SAs MUST have unique SPI.
- several hash tables added to speed up lookups in SADB.
- SADB now uses rmlock to protect access, and concurrent threads
can do SA lookups in the same time.
- many PF_KEY message handlers were reworked to reflect changes
in SADB.
- SADB_UPDATE message was extended to support new PF_KEY headers:
SADB_X_EXT_NEW_ADDRESS_SRC and SADB_X_EXT_NEW_ADDRESS_DST. They
can be used by IKE daemon to change SA addresses.
o ipsecrequest and secpolicy structures were cardinally changed to
avoid locking protection for ipsecrequest. Now we support
only limited number (4) of bundled SAs, but they are supported
for both INET and INET6.
o INPCB security policy cache was introduced. Each PCB now caches
used security policies to avoid SP lookup for each packet.
o For inbound security policies added the mode, when the kernel does
check for full history of applied IPsec transforms.
o References counting rules for security policies and security
associations were changed. The proper SA locking added into xform
code.
o xform code was also changed. Now it is possible to unregister xforms.
tdb_xxx structures were changed and renamed to reflect changes in
SADB/SPDB, and changed rules for locking and refcounting.

Recommit: Stop intercepting some malloc-related functions on FreeBSD
and macOS
Summary:
In https://bugs.freebsd.org/215125 I was notified that some configure
scripts attempt to test for the Linux-specific `mallinfo` and
`mallopt` functions by compiling and linking small programs which
references the functions, and observing whether that results in
errors.
FreeBSD and macOS do not have the `mallinfo` and `mallopt` functions,
so normally these tests would fail, but when sanitizers are enabled,
they incorrectly succeed, because the sanitizers define interceptors
for these functions. This also applies to some other malloc-related
functions, such as `memalign`, `pvalloc` and `cfree`.
Fix this by not intercepting `mallinfo`, `mallopt`, `memalign`,
`pvalloc` and `cfree` for FreeBSD and macOS, in all sanitizers.
Also delete the non-functional `cfree` wrapper for Windows, to fix the
test cases on that platform.

Recommit "Use ValueOffsetPair to enhance value reuse during SCEV
expansion".
The fix for PR28705 will be committed consecutively.
In D12090, the ExprValueMap was added to reuse existing value during
SCEV expansion. However, const folding and sext/zext distribution can
make the reuse still difficult.
A simplified case is: suppose we know S1 expands to V1 in
ExprValueMap, and
S1 = S2 + C_a
S3 = S2 + C_b
where C_a and C_b are different SCEVConstants. Then we'd like to
expand S3 as V1 - C_a + C_b instead of expanding S2 literally. It is
helpful when S2 is a complex SCEV expr and S2 has no entry in
ExprValueMap, which is usually caused by the fact that S3 is
generated from S1 after const folding.
In order to do that, we represent ExprValueMap as a mapping from SCEV
to ValueOffsetPair. We will save both S1->{V1, 0} and S2->{V1, C_a}
into the ExprValueMap when we create SCEV for V1. When S3 is
expanded, it will first expand S2 to V1 - C_a because of S2->{V1,
C_a} in the map, then expand S3 to V1 - C_a + C_b.
