some ctfmerge crashes that started to occur on i386 weeks after r274569 was
committed. Some later investigation indicated that the crashes were caused
by malformed CTF info that led to a stack overflow. The issue with CTF
info in i386 kernels seems to have been resolved by r261246, which updated
libdwarf and libelf.
r274569 fixes a bug which caused duplicate types to appear in the kernel's
CTF info. This duplication generally does not cause problems when using
DTrace, but makes it easier to hit the limit of 2^15 - 1 distinct type
definitions in a CTF container.

when it is being used in a build environment. This was previously worked
around by adding "-x nolibs" to dtrace -h or -G invocations, but as of
r283025, dtrace(1) actually handles dependencies properly, so this is no
longer necessary.

0. For spin events report time spent spinning, not a loop count.
While loop count is much easier and cheaper to obtain it is hard
to reason about the reported numbers, espcially for adaptive locks
where both spinning and sleeping can happen.
So, it's better to compare apples and apples.
1. Teach lockstat about FreeBSD rw locks.
This is done in part by changing the corresponding probes
and in part by changing what probes lockstat should expect.
2. Teach lockstat that rw locks are adaptive and can spin on FreeBSD.
3. Report lock acquisition events for successful rw try-lock operations.
4. Teach lockstat about FreeBSD sx locks.
Reporting of events for those locks completely mirrors
rw locks.
5. Report spin and block events before acquisition event.
This is behavior documented for the upstream, so it makes sense to stick
to it. Note that because of FreeBSD adaptive lock implementations
both the spin and block events may be reported for the same acquisition
while the upstream reports only one of them.

The "depends_on module" pragma can be used to declare a dependency on a

Therefore, allow a module dependency to be satisfied if either a kernel

next call to yyparse(). Fix this by explicitly flushing the input buffer

script. This reimplementation is much simpler than dtest.pl and is more
amenable to being run under Kyua - dtest.pl writes error output to a
temporary directory that is deleted when the run finishes, making it hard
to debug test failures. This change also removes the test suite's dependency
on perl.
ctf_add_type() first performs a by-name lookup of the type in the
destination container. If this lookup returns a forward declaration for an
enum, struct, or union, reset dst_type back to CTF_ERR, indicating that the
source type is not in fact present in the destination container. This
ensures that ctf_add_type() will also search the destination container's
dynamic type list for the source type.
Without this change, a pair of mutually recursive struct definitions could
cause infinite recursion in ctf_add_type() if the destination container
only contained forward declarations for the struct types: ctf_add_type()
recursively calls itself on each struct member's type, and the forward
declarations meant that the dynamic type list search would be skipped.

indicates the range of type indices which have been committed to the
container by ctf_update(). However, the top bit of the dtd_type field is
not part of the type index; rather, it is a flag used to indicate that the
corresponding CTF container is a parent. This is why the maximum CTF type
index is 2^15 - 1 rather than 2^16 - 1. Therefore, this flag must be masked
off (using the CTF_TYPE_TO_INDEX macro) when comparing a type index with the
ctf_dtoldid field of a container.
This bug was causing libctf to erroneously free committed type definitions

For each test category, we generate a script containing ATF test cases for
the tests under that category. Each test case simply runs dtest.pl (the
upstream test harness) with the corresponding test files. The exclude.sh
script is used to record info about tests which should be skipped or are
expected to fail; it is used to generate atf_skip and atf_expect_fail calls.
The genmakefiles.sh script can be used to regenerate the test makefiles when
new tests are brought it from upstream.
The test suite is currently not connected to the build as there is a small
number of lingering test issues which still need to be worked out. In the
meantime however, the test suite can be easily built and installed
manually from cddl/usr.sbin/dtrace/tests.

__SUNW_dof symbol defined in each file is global. This is handled by
using objcopy(1) to convert __SUNW_dof to a local symbol once drti.o has
been linked with the generated object file. Upstream, this is done using a
