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

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.

Implement kernel support for hardware rate limited sockets. - Add RATELIMIT kernel configuration keyword which must be set to enable the new functionality. - Add support for hardware driven, Receive Side Scaling, RSS aware, rate limited sendqueues and expose the functionality through the already established SO_MAX_PACING_RATE setsockopt(). The API support rates in the range from 1 to 4Gbytes/s which are suitable for regular TCP and UDP streams. The setsockopt(2) manual page has been updated. - Add rate limit function callback API to "struct ifnet" which supports the following operations: if_snd_tag_alloc(), if_snd_tag_modify(), if_snd_tag_query() and if_snd_tag_free(). - Add support to ifconfig to view, set and clear the IFCAP_TXRTLMT flag, which tells if a network driver supports rate limiting or not. - This patch also adds support for rate limiting through VLAN and LAGG intermediate network devices. - How rate limiting works: 1) The userspace application calls setsockopt() after accepting or making a new connection to set the rate which is then stored in the socket structure in the kernel. Later on when packets are transmitted a check is made in the transmit path for rate changes. A rate change implies a non-blocking ifp->if_snd_tag_alloc() call will be made to the destination network interface, which then sets up a custom sendqueue with the given rate limitation parameter. A "struct m_snd_tag" pointer is returned which serves as a "snd_tag" hint in the m_pkthdr for the subsequently transmitted mbufs. 2) When the network driver sees the "m->m_pkthdr.snd_tag" different from NULL, it will move the packets into a designated rate limited sendqueue given by the snd_tag pointer. It is up to the individual drivers how the rate limited traffic will be rate limited. 3) Route changes are detected by the NIC drivers in the ifp->if_transmit() routine when the ifnet pointer in the incoming snd_tag mismatches the one of the network interface. The network adapter frees the mbuf and returns EAGAIN which causes the ip_output() to release and clear the send tag. Upon next ip_output() a new "snd_tag" will be tried allocated. 4) When the PCB is detached the custom sendqueue will be released by a non-blocking ifp->if_snd_tag_free() call to the currently bound network interface.

Also note that kernel config files are not affected by MK_ options listed, though some targets might be.

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

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.
