Add _fib versions of ifa_ifwithnet() and ifa_ifwithdstaddr() The legacy functions will call the _fib() versions with RT_ALL_FIBS, preserving legacy behavior. sys/net/if_var.h sys/net/if.c Add legacy-compatible functions as described above. Ensure legacy behavior when RT_ALL_FIBS is passed as fibnum. sys/netinet/in_pcb.c sys/netinet/ip_output.c sys/netinet/ip_options.c sys/net/route.c sys/net/rtsock.c sys/netinet6/nd6.c Call with _fib() functions if we must use a specific fib, or the legacy functions otherwise. tests/sys/netinet/fibs_test.sh tests/sys/netinet/udp_dontroute.c Improve the udp_dontroute test. The bug that this test exercises is that ifa_ifwithnet() will return the wrong address, if multiple interfaces have addresses on the same subnet but with different fibs. The previous version of the test only considered one possible failure mode: that ifa_ifwithnet_fib() might fail to find any suitable address at all. The new version also checks whether ifa_ifwithnet_fib() finds the correct address by checking where the ARP request goes.

src/tests: The FreeBSD test suite
=================================

This file describes the build infrastructure of the FreeBSD test suite.
If you are only interested in using the test suite itself, please refer
to tests(7) instead.

The build of the test suite is organized in the following manner:

* The build of all test artifacts is protected by the MK_TESTS knob.
  The user can disable these with the WITHOUT_TESTS setting in
  src.conf(5).

* The goal for /usr/tests/ (the installed test programs) is to follow
  the same hierarchy as /usr/src/ wherever possible, which in turn drives
  several of the design decisions described below.  This simplifies the
  discoverability of tests.  We want a mapping such as:

    /usr/src/bin/cp/      -> /usr/tests/bin/cp/
    /usr/src/lib/libc/    -> /usr/tests/lib/libc/
    /usr/src/usr.bin/cut/ -> /usr/tests/usr.bin/cut/
    ... and many more ...

* Test programs for specific utilities and libraries are located next
  to the source code of such programs.  For example, the tests for the
  src/lib/libcrypt/ library live in src/lib/libcrypt/tests/.  The tests/
  subdirectory is optional and should, in general, be avoided.

* The src/tests/ hierarchy (this directory) provides generic test
  infrastructure and glue code to join all test programs together into
  a single test suite definition.

* The src/tests/ hierarchy also includes cross-functional test programs:
  i.e. test programs that cover more than a single utility or library
  and thus don't fit anywhere else in the tree.  Consider this to follow
  the same rationale as src/share/man/: this directory contains generic
  manual pages while the manual pages that are specific to individual
  tools or libraries live next to the source code.

In order to keep the src/tests/ hierarchy decoupled from the actual test
programs being installed --which is a worthy goal because it simplifies
the addition of new test programs and simplifies the maintenance of the
tree-- the top-level Kyuafile does not know which subdirectories may
exist upfront.  Instead, such Kyuafile automatically detects, at
run-time, which */Kyuafile files exist and uses those directly.

Similarly, every directory in src/ that wants to install a Kyuafile to
just recurse into other subdirectories reuses this Kyuafile with
auto-discovery features.  As an example, take a look at src/lib/tests/
whose sole purpose is to install a Kyuafile into /usr/tests/lib/.
The goal in this specific case is for /usr/tests/lib/ to be generated
entirely from src/lib/.
