Introduce kern.opts.mk to hold all the options for kernel module builds. Include this in the right places. Make src.opts.mk optional so that modules can be built outside of the tree in the ports system. PR: 189520

# $FreeBSD$
# Options set in the build system that affect the kernel somehow.
#
# Define MK_* variables (which are either "yes" or "no") for users
# to set via WITH_*/WITHOUT_* in /etc/src.conf and override in the
# make(1) environment.
# These should be tested with `== "no"' or `!= "no"' in makefiles.
# The NO_* variables should only be set by makefiles for variables
# that haven't been converted over.

Remove dependence on source tree options. Move all kernel module options into kern.opts.mk and change all the places where we use src.opts.mk to pull in the options. Conditionally define SYSDIR and use SYSDIR/conf/kern.opts.mk instead of a CURDIR path. Replace all instances of CURDIR/../../etc with STSDIR, but only in the affected files. As a special compatibility hack, include bsd.owm.mk at the top of kern.opts.mk to allow the bare build of sys/modules to work on older systems. If the defaults ever change between 9.x, 10.x and current for these options, however, you'll wind up with the host OS' defaults rather than the -current defaults. This hack will be removed when we no longer need to support this build scenario. Reviewed by: jhb Differential Revision: https://phabric.freebsd.org/D529

IPFILTER \
Merge projects/ipsec into head/. 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.

Change the default build behavior so we don't compile extra TCP modules by default. At least initially, the feature to support multiple TCP stacks is aimed at supporting advanced use cases and TCP development, but it is not necessarily aimed at a wide audience. Therefore, there is no need to build and install the extra TCP stacks by default. Instead, the people who are using or developing this functionality can add the extra option to build/ install the extra TCP stacks. However, we do want to build the extra TCP stacks as part of test builds (e.g. LINT or tinderbox) to ensure that developers who are testing their changes will know that their changes do not break the additional TCP stack modules. After this change, a user will need to add WITH_EXTRA_TCP_STACKS=1 to make.conf or the kernel config in order to build the extra TCP modules.

Remove dependence on source tree options. Move all kernel module options into kern.opts.mk and change all the places where we use src.opts.mk to pull in the options. Conditionally define SYSDIR and use SYSDIR/conf/kern.opts.mk instead of a CURDIR path. Replace all instances of CURDIR/../../etc with STSDIR, but only in the affected files. As a special compatibility hack, include bsd.owm.mk at the top of kern.opts.mk to allow the bare build of sys/modules to work on older systems. If the defaults ever change between 9.x, 10.x and current for these options, however, you'll wind up with the host OS' defaults rather than the -current defaults. This hack will be removed when we no longer need to support this build scenario. Reviewed by: jhb Differential Revision: https://phabric.freebsd.org/D529

.undef __DEFAULT_NO_OPTIONS
Add support for specifying unsupported / broken options that override any defaults or user specified actions on the command line. This would be useful for specifying features that are always broken or that cannot make sense on a specific architecture, like ACPI on pc98 or EISA on !i386 (!x86 usage of EISA is broken and there's no supported hardware that could have it in any event). Any items in BROKEN_OPTIONS are forced to "no" regardless of other settings. Clients are expected change BROKEN_OPTIONS with +=. It will not be unset, so other parts of the build system can have visibility into the options that are broken on this platform, though this should be very rare.

When building modules, define make variable OPT_FDT if the kernel config includes the FDT option. Use OPT_FDT to conditionally compile modules that require FDT support. In the past we've gotten away with using the arch name as a proxy for FDT support in makefile conditional logic, but now mips has some platforms with fdt support and some without and we need a more direct test.
