## News

* lib.libcasper.services.cap_net.net_test.* tests are temporarily disabled
in CI env due to require to access public Internet, which is currently
unavailable in the test VM execution environment. Safe internet access
of the test VM is WIP but it is suggested writing tests without external
dependenies. This is why the total case number dropped.

## Failing jobs

* https://ci.freebsd.org/job/FreeBSD-head-amd64-gcc6_build/
There are still mutiple errors when building with gcc6, error log available at
https://ci.freebsd.org/job/FreeBSD-head-amd64-gcc6_build/lastCompletedBuild/console

## Failing test cases

* sys.kern.kern_copyin.kern_copyin
Fails after somewhere in (r364509, r364542]
https://bugs.freebsd.org/248933

## Regressions

* lib.libexecinfo.backtrace_test.backtrace_fmt_basic starts failing on amd64 after r360915
https://bugs.freebsd.org/246537

* lib.msun.ctrig_test.test_inf_inputs starts failing after llvm10 import
https://bugs.freebsd.org/244732
Needs to check if llvm11 import fixes this.

* Lock-order reversals triggered by tests under sys.net.if_lagg_test.* on i386
https://bugs.freebsd.org/244163
Discovered by newly endabled sys.net.* tests. ([r357857](https://svnweb.freebsd.org/changeset/base/357857))

* sys.net.if_lagg_test.lacp_linkstate_destroy_stress panics i386 kernel
https://bugs.freebsd.org/244168
Discovered by newly endabled sys.net.* tests. ([r357857](https://svnweb.freebsd.org/changeset/base/357857))
Fix committed as https://svnweb.freebsd.org/changeset/base/364220 , needs more verification.
