Add .../share/mk to the default system make path. This will fix the problem
with broken in-tree builds (which are used far more pervasively than I'd
known outside the tree). However, weird results may now happen if at any
point in the tree above you there happens to be a directory that has
subdirectory of share/mk, as unpredictable results will follow. This was
considered the lessor of the two evils, at least for now. In the future this
will be removed again when the underlying issues are resolved.
For MFCing, this is to ensure that when upgrading to head the share/mk
in-tree is always used. Otherwise several build features will not work.
This passes a build using head's bmake which has this as the default
already.

install: do not follow symlinks
In case the target of install is a dead symlink, install(1) used to not
consider it as "existing" because of the usage of stat(2) instead of
lstat(2). meaning the old file (the symlink) is not removed before the new
file is created. The symlink is being followed and the new file becoming the
target of the symlink instead of the target of install(1)

Integrate the tests from lib/libarchive, usr.bin/cpio, and usr.bin/tar in to

functional_test.sh was ported from bin/sh/tests/functional_test.sh, as a

by upstream.
A handful of testcases in lib/libarchive/tests have been disabled as they
were failing when run with kyua test (see BROKEN_TESTS in

As a sidenote: this removes the check/test targets from the Makefiles as they

Merge most of the recent changes to truss in HEAD. The largest effects
are that fork following now uses a single truss process (and thus truss -c
reports counts for the entire tree of processes instead of separate dumps
for each process). truss -c also reports counts for all system calls
instead of only a subset. More system call arguments are also decoded.
System calls should now report the correct number of arguments (instead
of 6), and some platforms that did not properly decode arguments might
now do so (e.g. mips64).
Changes relative to the equivalent commits to HEAD include:
- The ia64 backend was refactored similar to the other backends.
- _umtx_lock/_umtx_unlock entries were updated similar to other system
call entries.
- 10 does not have futimens(), utimensat(), EVFILT_PROCDESC, EVFILT_SENDFILE,
RLIMIT_KQUEUES, O_VERIFY, NOTE_FILE_POLL, or EV_FORCEONESHOT.

Rework get_string() to make it more robust when fetching strings of unknown
length. In particular, instead of blinding fetching 1k blocks, do an initial
fetch up to the end of the current page followed by page-sized fetches up to
the maximum size. Previously if the 1k buffer crossed a page boundary and
the second page was not valid, the entire operation would fail.

Add recently added values of various flags and enumerations including

Decode the arguments to mkfifo() and fix an off-by-one error in the arguments

286381:
Decode the arguments passed to the *at() family of system calls. This is
especially useful now that libc's open() always calls openat(). While here,
fix a few other things:
- Decode the mode argument passed to access(), eaccess(), and faccessat().
- Decode the atfd paramete to pretty-print AT_FDCWD.
- Decode the special AT_* flags used with some of the *at() system calls.
- Decode arguments for fchmod(), lchmod(), fchown(), lchown(), eaccess(),
and futimens().
- Decode both of the timeval structures passed to futimes() instead of just
the first one.
286383:
Whitespace fixes to consistently use spaces before }'s and
wrap long lines.
286388:
Consistently use both leading and trailing spaces inside of the {}'s

286848:
- Decode the arguments for several signal-related system calls: sigpending,
sigqueue, sigreturn, sigsuspend, sigtimedwait, sigwait, sigwaitinfo, and
thr_kill.
- Print signal sets as a structure (with {}'s) and in particular use this to
differentiate empty sets from a NULL pointer.
- Decode arguments for some other system calls: issetugid, pipe2, sysarch
(operations are only decoded for amd64 and i386), and thr_self.
286849:
Decode the optional SOCK_NONBLOCK and SOCK_CLOEXEC flags passed in a
socket type.
286857:
Tidy the linux_socketcall decoding:
- Don't exit if get_struct() fails, instead print the raw pointer value to
match all other argument decoding cases.
- Use an xlat table instead of a home-rolled switch for the operation name.
- Display the nested socketcall args structure as a structure instead of as
two inline arguments.
286860:
Use an xlat table and xlookup() instead of a home-rolled version for the

286913:
Change the argument formatting function to use a stdio FILE object opened
with open_memstream() to build the string for each argument. This allows
for more complicated argument building without resorting to intermediate
malloc's, etc.
Related, the strsig*() functions no longer return allocated strings but
use a static global buffer instead.
286914:
Expand the decoding of kevent structures.
- Print the ident value as decimal instead of hexadecimal for filter types
that use "small" values such as file descriptors and PIDs.
- Decode NOTE_* flags in the fflags field of kevents for several system
filter types.
286937:
Use nitems().
286938:
Various style and whitespace fixes.
287939:
Always use %j with an intmax_t cast to print time_t values. time_t is
longer than long on 32-bit platforms with a 64-bit time_t.
286940:
ino_t is unsigned, so use uintmax_t instead of intmax_t when printing it.
286962:
Rework the argv and env string fetching for execve to be more robust.
Before truss would fetch 100 string pointers and happily walk off the end
of the array if it never found a NULL. This also means for a short argv
list it could fail entirely if the 100 string pointers spanned into an
unmapped page.
Instead, fetch page-aligned blocks of string pointers in a loop fetching
each string until a NULL is found.
While here, make use of the open memstream file descriptor instead of
allocating a temporary array. This allows us to fetch each string once
instead of twice.
286963:
Handle the conditional decoding of execve() argument and environment
arrays generically rather than duplicating a hack in all of the backends.
- Add two new system call argument types and use them instead of StringArray
for the argument and environment arguments execve and linux_execve.
- Honor the -a/-e flags in the handling of these new types.
- Instead of printing "<missing argument>" when the decoding is disabled,
print the raw pointer value.
288405:
Decode recently added procctl(2) operations.
288406:
Trim trailing whitespace.
288424:
Several changes to truss.
- Refactor the interface between the ABI-independent code and the
ABI-specific backends. The backends now provide smaller hooks to
fetch system call arguments and return values. The rest of the
system call entry and exit handling that was previously duplicated
among all the backends has been moved to one place.
- Merge the loop when waiting for an event with the loop for handling stops.
This also means not emulating a procfs-like interface on top of ptrace().
Instead, use a single event loop that fetches process events via waitid().
Among other things this allows us to report the full 32-bit exit value.
- Use PT_FOLLOW_FORK to follow new child processes instead of forking a new
truss process for each new child. This allows one truss process to monitor
a tree of processes and truss -c should now display one total for the
entire tree instead of separate summaries per process.
- Use the recently added fields to ptrace_lwpinfo to determine the current
system call number and argument count. The latter is especially useful
and fixes a regression since the conversion from procfs. truss now
generally prints the correct number of arguments for most system calls
rather than printing extra arguments for any call not listed in the
table in syscalls.c.
- Actually check the new ABI when processes call exec. The comments claimed
that this happened but it was not being done (perhaps this was another
regression in the conversion to ptrace()). If the new ABI after exec
is not supported, truss detaches from the process. If truss does not
support the ABI for a newly executed process the process is killed
before it returns from exec.
- Along with the refactor, teach the various ABI-specific backends to
fetch both return values, not just the first. Use this to properly
report the full 64-bit return value from lseek(). In addition, the
handler for "pipe" now pulls the pair of descriptors out of the
return values (which is the true kernel system call interface) but
displays them as an argument (which matches the interface exported by
libc).
- Each ABI handler adds entries to a linker set rather than requiring
a statically defined table of handlers in main.c.
- The arm and mips system call fetching code was changed to follow the
same pattern as amd64 (and the in-kernel handler) of fetching register
arguments first and then reading any remaining arguments from the
stack. This should fix indirect system call arguments on at least
arm.
- The mipsn32 and n64 ABIs will now look for arguments in A4 through A7.
- Use register %ebp for the 6th system call argument for Linux/i386 ABIs
to match the in-kernel argument fetch code.
- For powerpc binaries on a powerpc64 system, fetch the extra arguments
on the stack as 32-bit values that are then copied into the 64-bit
argument array instead of reading the 32-bit values directly into the
64-bit array.
288454:
- Remove extra integer argument from truncate() and ftruncate(). This is
probably fallout from the removal of the extra padding argument before
off_t in 7. However, that padding still exists for 32-bit powerpc, so
use QUAD_ALIGN.
- Fix QUAD_ALIGN to be zero for powerpc64. It should only be set to 1
for 32-bit platforms that add padding to align 64-bit arguments.
288455:
The id_t type used to pass IDs to wait6(2) and procctl(6) is a 64-bit
integer. Fix the argument decoding to treat this as a quad instead of an
int. This includes using QUAD_ALIGN and QUAD_SLOTS as necessary. To
continue printing IDs in decimal, add a new QuadHex argument type that
prints a 64-bit integer in hex, use QuadHex for the existing off_t arguments,
repurpose Quad to print a 64-bit integer in decimal, and use Quad for id_t
arguments.
This fixes the decoding of wait6(2) and procctl(2) on 32-bit platforms.
288456:
Rather than groveling around in a socket address structure for a socket
address's length (and then overriding it if it "looks wrong"), use the
next argument to the system call to determine the length. This is more
reliable since this is what the kernel depends on anyway and is also
simpler.
288625:
Add decoding for struct statfs.
288626:
Style fix.
288832:
Fix tracking of unknown syscalls for 'truss -c'.
This is done by changing get_syscall() to either lookup the known syscall
or add it into the list with the default handlers for printing.
This also simplifies some code to not have to check if the syscall variable
is set or NULL.
288834:
Add decoding for modfind(2)
288950:
Group the decoded system calls by ABI and sort the calls within each ABI.
288997:
Correct a comment.
289080:
Let -c imply -S (hide signal output).
Without this, the signals are shown seemingly randomly in the output before
