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.

Initial support for bhyve save and restore. Save and restore (also known as suspend and resume) permits a snapshot to be taken of a guest's state that can later be resumed. In the current implementation, bhyve(8) creates a UNIX domain socket that is used by bhyvectl(8) to send a request to save a snapshot (and optionally exit after the snapshot has been taken). A snapshot currently consists of two files: the first holds a copy of guest RAM, and the second file holds other guest state such as vCPU register values and device model state. To resume a guest, bhyve(8) must be started with a matching pair of command line arguments to instantiate the same set of device models as well as a pointer to the saved snapshot. While the current implementation is useful for several uses cases, it has a few limitations. The file format for saving the guest state is tied to the ABI of internal bhyve structures and is not self-describing (in that it does not communicate the set of device models present in the system). In addition, the state saved for some device models closely matches the internal data structures which might prove a challenge for compatibility of snapshot files across a range of bhyve versions. The file format also does not currently support versioning of individual chunks of state. As a result, the current file format is not a fixed binary format and future revisions to save and restore will break binary compatiblity of snapshot files. The goal is to move to a more flexible format that adds versioning, etc. and at that point to commit to providing a reasonable level of compatibility. As a result, the current implementation is not enabled by default. It can be enabled via the WITH_BHYVE_SNAPSHOT=yes option for userland builds, and the kernel option BHYVE_SHAPSHOT.

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

Attempt to walk a fine line between current usage (/usr/ports which does an out-of-tree build without setting MAKESYSPATH) and recently added requirements (JIRA's building the modules in a non-standard layout). So, when MAKESYSPATH is defined, trust that it will do the right thing (to catch the JIRA use case). When it isn't defined, assume a standard FreeBSD tree and reach over to grab bsd.mkopt.mk (to fix the /usr/ports use case). Both camps cannot be appeased otherwise, so we have this kludge until it can be sorted out.

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.

Add SPLIT_KERNEL_DEBUG knob Prior to 9b6edf364eb0 WITHOUT_KERNEL_SYMBOLS split kernel debug data into standalone debug files at build time, but did not install those files. As of 9b6edf364eb0 it stopped splitting the debug data, leaving it in the kernel and modules (the default kernel configs include DEBUG=-g). Revert 9b6edf364eb0 and introduce a new build-time SPLIT_KERNEL_DEBUG knob, as some people rely on the pre-9b6edf364eb0 WITHOUT_KERNEL_SYMBOLS behaviour and that was imp's original intent.

cddl/*: add a WITH(OUT)_DTRACE option Add an option to enable/disable DTrace without disabling ZFS. New architectures such as CHERI may support ZFS before they support DTrace and the old model of WITHOUT_CDDL disabling both wasn't helpful. For compatiblity, the CDDL option remains and WITHOUT_CDDL implies WITHOUT_DTRACE. WITHOUT_DTRACE also implies WITHOUT_CTF. As part of this change, largely convert cddl/*/Makefile to using the more compact SUBDIR.${MK_<FOO>}+= form rather than using intermediate variables.
