42668853c0 tcpdump: disable Capsicum if -E option is provided.
The -E is used to provide a secret for decrypting IPsec.
The secret may be provided through command line or as the file.
The problem is that tcpdump doesn't support yet opening files in capability mode
and the file may contain a list of the files to open.

As a workaround, for now, let's just disable capsicum if the -E

48e091f99d Follow the declared behaviour that specifies server string format in
bsnmpclient(3).

snmp_parse_server() function accepts string where some fields can be
omitted: [trans::][community@][server][:port]

"trans" field can be "udp", "udp6", "dgram" and "stream".
"community" can be empty string, if it is omitted, the default value
will be used. For read_community it is "public", for write_comminity
it is "private". "server" field can be hostname, IPv4 address or IPv6
address. IPv6 address should be specified in brackets "[]".
If port is omitted, the default value "snmp" will be used for "udp"
and "udp6" transports. So, now for bsnmpget(1) and bsnmwalk(1) it is
not required to specify all fields in argument of '-s' option. E.g.

  # bsnmpget -s 127.1 sysName.0
  # bsnmpget -s "udp::127.1" sysName.0
  # bsnmpget -s "udp::public@127.1" sysName.0
  # bsnmpget -s "udp::public@127.1:161" sysName.0
  # bsnmpget -s "udp::[::1]" sysName.0
  # bsnmpget -s "udp6::[::1]" sysName.0
  # bsnmpget -s "[fe80::1%lo0]" sysName.0

8ac5aef8f3 Integrate capsicum-test into the FreeBSD test suite
This change takes capsicum-test from upstream and applies some local changes to make the
tests work on FreeBSD when executed via Kyua.

The local modifications are as follows:
1. Make `OpenatTest.WithFlag` pass with the new dot-dot lookup behavior in FreeBSD 12.x+.
2. capsicum-test references a set of helper binaries: `mini-me`, `mini-me.noexec`, and
   `mini-me.setuid`, as part of the execve/fexecve tests, via execve, fexecve, and open.
   It achieves this upstream by assuming `mini-me*` is in the current directory, however,
   in order for Kyua to execute `capsicum-test`, it needs to provide a full path to
   `mini-me*`. In order to achieve this, I made `capsicum-test` cache the executable's
   path from argv[0] in main(..) and use the cached value to compute the path to
   `mini-me*` as part of the execve/fexecve testcases.
3. The capsicum-test test suite assumes that it's always being run on CAPABILITIES enabled
   kernels. However, there's a chance that the test will be run on a host without a
   CAPABILITIES enabled kernel, so we must check for the support before running the tests.
   The way to achieve this is to add the relevant `feature_present("security_capabilities")`
   check to SetupEnvironment::SetUp() and skip the tests when the support is not available.
   While here, add a check for `kern.trap_enotcap` being enabled. As noted by markj@ in
   https://github.com/google/capsicum-test/issues/23, this sysctl being enabled can trigger
   non-deterministic failures. Therefore, the tests should be skipped if this sysctl is
   enabled.

All local changes have been submitted to the capsicum-test project
(https://github.com/google/capsicum-test) and are in various stages of review.
Please see the following pull requests for more details:
1. https://github.com/google/capsicum-test/pull/35

e9e2022e74 Import proof-of-concept for handling GTEST_SKIP() in Environment::SetUp
Per the upstream pull-request [1]:

```
  gtest prior to this change would completely ignore `GTEST_SKIP()` if
  called in `Environment::SetUp()`, instead of bailing out early, unlike
  `Test::SetUp()`, which would cause the tests themselves to be skipped.
  The only way (prior to this change) to skip the tests would be to
  trigger a fatal error via `GTEST_FAIL()`.

  Desirable behavior, in this case, when dealing with
  `Environment::SetUp()` is to check for prerequisites on a system
  (example, kernel supports a particular featureset, e.g., capsicum), and
  skip the tests. The alternatives prior to this change would be
  undesirable:

  - Failing sends the wrong message to the test user, as the result of the
    tests is indeterminate, not failed.
  - Having to add per-test class abstractions that override `SetUp()` to
    test for the capsicum feature set, then skip all of the tests in their
    respective SetUp fixtures, would be a lot of human and computational
    work; checking for the feature would need to be done for all of the
    tests, instead of once for all of the tests.

  For those reasons, making `Environment::SetUp()` handle `GTEST_SKIP()`,
  by not executing the testcases, is the most desirable solution.

  In order to properly diagnose what happened when running the tests if
  they are skipped, print out the diagnostics in an ad hoc manner.

  Update the documentation to note this change and integrate a new test,
  gtest_skip_in_environment_setup_test, into the test suite.

  This change addresses #2189.

  Signed-off-by: Enji Cooper <yaneurabeya@gmail.com>
```

The goal with my merging in this change is to avoid requiring extensive
refactoring/retesting of test suites when ensuring prerequisites are met,
e.g., checking for a CAPABILITIES-enabled kernel before running capsicum-test
(see D19758 for more details).

The proof-of-concept is being imported before accepted by the upstream
project due to the fact that the upstream project is undergoing a potential
development freeze and the maintainers aren't responding to my PR.

1fc6236006 Prepend DW_AT_comp_dir to relative line number directory table entries.
Relative directories may appear in the line number program for a CPU if
files were included via a relative path, for instance with "-I.".
Previously, dwarf_srclines(3) and dwarf_srcfiles(3) would return the
relative path, so addr2line, for instance, would do the same.  However,
we can get an absolute path by prepending the compilation directory, so
change libdwarf to do that to improve compatibility with GNU binutils
and since it is more useful in general.

c3e6b9d390 Pull in r352826 from upstream lld trunk (by Fangrui Song):
[ELF] Support --{,no-}allow-shlib-undefined

  Summary:
  In ld.bfd/gold, --no-allow-shlib-undefined is the default when
  linking an executable. This patch implements a check to error on
  undefined symbols in a shared object, if all of its DT_NEEDED entries
  are seen.

  Our approach resembles the one used in gold, achieves a good balance
  to be useful but not too smart (ld.bfd traces all DSOs and emulates
  the behavior of a dynamic linker to catch more cases).

  The error is issued based on the symbol table, different from
  undefined reference errors issued for relocations. It is most
  effective when there are DSOs that were not linked with -z defs (e.g.
  when static sanitizers runtime is used).

  gold has a comment that some system libraries on GNU/Linux may have
  spurious undefined references and thus system libraries should be
  excluded (https://sourceware.org/bugzilla/show_bug.cgi?id=6811). The
  story may have changed now but we make --allow-shlib-undefined the
  default for now. Its interaction with -shared can be discussed in the
  future.

  [ELF] Default to --no-allow-shlib-undefined for executables

  Summary:
  This follows the ld.bfd/gold behavior.

  The error check is useful as it captures a common type of ld.so
  undefined symbol errors as link-time errors:

      // a.cc => a.so (not linked with -z defs)
      void f(); // f is undefined
      void g() { f(); }

      // b.cc => executable with a DT_NEEDED entry on a.so
      void g();
      int main() { g(); }

      // ld.so errors when g() is executed (lazy binding) or when the program is started (-z now)
      // symbol lookup error: ... undefined symbol: f

Together, these add support for --no-allow-shlib-undefined, and make it

b603a4c616 Add LLVM openmp trunk r351319 (just before the release_80 branch point)
to contrib/llvm.  This is not yet connected to the build, the glue for
that will come in a follow-up commit.

5193fcde8d Initial googlemock/googletest integration into the build/FreeBSD test suite
This initial integration takes googlemock/googletest release 1.8.1, integrates
the library, tests, and sample unit tests into the build.

googlemock/googletest's inclusion is optionally available via `MK_GOOGLETEST`.
`MK_GOOGLETEST` is dependent on `MK_TESTS` and is enabled by default when
built with a C++11 capable toolchain.

Google tests can be specified via the `GTESTS` variable, which, in comparison
with the other test drivers, is more simplified/streamlined, as Googletest only
supports C++ tests; not raw C or shell tests (C tests can be written in C++
using the standard embedding methods).

No dependent libraries are assumed for the tests. One must specify `gmock`,
`gmock_main`, `gtest`, or `gtest_main`, via `LIBADD` for the program.

More information about googlemock and googletest can be found on the
Googletest [project page](https://github.com/google/googletest), and the
[GoogleMock](https://github.com/google/googletest/blob/v1.8.x/googlemock/docs/Documentation.md)
and
[GoogleTest](https://github.com/google/googletest/tree/v1.8.x/googletest/docs)
docs.

These tests are originally integrated into the build as plain driver tests, but
will be natively integrated into Kyua in a later version.

Known issues/Errata:
* [WhenDynamicCastToTest.AmbiguousCast fails on FreeBSD](https://github.com/google/googletest/issues/2172)

4cc79e8968 Revert r308867 (which was originally committed in the clang390-import
project branch):

  Work around LLVM PR30879, which is about a bad interaction between
  X86 Call Frame Optimization on i386 and libunwind, by disallowing the
  optimization for i386-freebsd12.

  This should fix some instances of broken exception handling when
  frame pointers are omitted, in particular some unittests run during
  the build of editors/libreoffice.

  This hack will be removed as soon as upstream has implemented a more
  permanent fix for this problem.

And indeed, after r345018 and r345019, which updated LLVM libunwind to
the most recent version, the above workaround is no longer needed.  The
upstream commit which fixed this is:

  https://llvm.org/viewvc/llvm-project?view=revision&revision=292723

Specifically, 32 bit (i386-freebsd) executables optimized with omitted
frame pointers and Call Frame Optimization should now behave correctly
when a C++ exception is thrown, and the stack is unwound.

c8a048a4a3 Move libunwind out of contrib/llvm/projects.
Move LLVM's libunwind to its own contrib/ directory similar to other
runtime libraries like libc++ and libcxxrt.

e6ec44cf36 Pull in r355854 from upstream llvm trunk (by Jonas Paulsson):
[RegAlloc]  Avoid compile time regression with multiple copy hints.

  As a fix for https://bugs.llvm.org/show_bug.cgi?id=40986 ("excessive
  compile time building opencollada"), this patch makes sure that no
  phys reg is hinted more than once from getRegAllocationHints().

  This handles the case were many virtual registers are assigned to the
  same physreg. The previous compile time fix (r343686) in
  weightCalcHelper() only made sure that physical/virtual registers are
  passed no more than once to addRegAllocationHint().

  Review: Dimitry Andric, Quentin Colombet
  https://reviews.llvm.org/D59201

This should fix a hang when compiling certain generated .cpp files in
the graphics/opencollada port.
