Replace the CloudABI system call table by a machine generated version.
The type definitions and constants that were used by COMPAT_CLOUDABI64 are a literal copy of some headers stored inside of CloudABI's C library, cloudlibc. What is annoying is that we can't make use of cloudlibc's system call list, as the format is completely different and doesn't provide enough information. It had to be synced in manually.
We recently decided to solve this (and some other problems) by moving the ABI definitions into a separate file:
https://github.com/NuxiNL/cloudabi/blob/master/cloudabi.txt
This file is processed by a pile of Python scripts to generate the header files like before, documentation (markdown), but in our case more importantly: a FreeBSD system call table.
This change discards the old files in sys/contrib/cloudabi and replaces them by the latest copies, which requires some minor changes here and there. Because cloudabi.txt also enforces consistent names of the system call arguments, we have to patch up a small number of system call implementations to use the new argument names.
The new header files can also be included directly in FreeBSD kernel space without needing any includes/defines, so we can now remove cloudabi_syscalldefs.h and cloudabi64_syscalldefs.h. Patch up the sources to include the definitions directly from sys/contrib/cloudabi instead.

Use ptrace(2) LWP events to track threads reliably in truss.
- truss can now log the system call invoked by a thread during a voluntary process exit. No return value is logged, but the value passed to exit() is included in the trace output. Arguments passed to thread exit system calls such as thr_exit() are not logged as voluntary thread exits cannot be distinguished from involuntary thread exits during a system call. - New events are now reported for thread births and exits similar to the recently added events for new child processes when following forks.

Add handling for non-native error values to libsysdecode.
Add two new functions, sysdecode_abi_to_freebsd_errno() and sysdecode_freebsd_to_abi_errno(), which convert errno values between the native FreeBSD ABI and other supported ABIs. Note that the mappings are not necessarily perfect meaning in some cases multiple errors in one ABI might map to a single error in another ABI. In that case, the reverse mapping will return one of the errors that maps, but which error is non-deterministic.
Change truss to always report the raw error value to the user but use libsysdecode to map it to a native errno value that can be used with strerror() to generate a description. Previously truss reported the "converted" error value. Now the user will always see the exact error value that the application sees.
Change kdump to report the truly raw error value to the user. Previously kdump would report the absolute value of the raw error value (so for Linux binaries it didn't output the FreeBSD error value, but the positive value of the Linux error). Now it reports the real (i.e. negative) error value for Linux binaries. Also, use libsysdecode to convert the native FreeBSD error reported in the ktrace record to the raw error used by the ABI. This means that the Linux ABI can now be handled directly in ktrsysret() and removes the need for linux_ktrsysret().

Move the mkioctls script to libsysdecode and use it to generate a sysdecode_ioctlname() function. This function matches the behavior of the truss variant in that it returns a pointer to a string description for known ioctls. The caller is responsible for displaying unknown ioctl requests. For kdump this meant moving the logic to handle unknown ioctl requests out of the generated function and into an ioctlname() function in kdump.c instead.

Start on a new library (libsysdecode) that provides routines for decoding system call information such as system call arguments. Initially this will consist of pulling duplicated code out of truss and kdump though it may prove useful for other utilities in the future.
This commit moves the shared utrace(2) record parser out of kdump into the library and updates kdump and truss to use it. One difference from the previous version is that the library version treats unknown events that start with the "RTLD" signature as unknown events. This simplifies the interface and allows the consumer to decide how to handle all non-recognized events. Instead, this function only generates a string description for known malloc() and RTLD records.

Properly format pointer size independent CloudABI system calls.
CloudABI has approximately 50 system calls that do not depend on the pointer size of the system. As the ABI is pretty compact, it takes little effort to each truss(8) the formatting rules for these system calls. Start off by formatting pointer size independent system calls.
Changes:
- Make it possible to include the CloudABI system call definitions in FreeBSD userspace builds. Add ${root}/sys to the truss(8) Makefile so we can pull in <compat/cloudabi/cloudabi_syscalldefs.h>. - Refactoring: patch up amd64-cloudabi64.c to use the CLOUDABI_* constants instead of rolling our own table. - Add table entries for all of the system calls. - Add new generic formatting types (UInt, IntArray) that we'll be using to format unsigned integers and arrays of integers. - Add CloudABI specific formatting types.

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.

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.

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.

The current POSIX semaphore implementation stores the _has_waiters flag in a separate word from the _count. This does not permit both items to be updated atomically in a portable manner. As a result, sem_post() must always perform a system call to safely clear _has_waiters.
This change removes the _has_waiters field and instead uses the high bit of _count as the _has_waiters flag. A new umtx object type (_usem2) and two new umtx operations are added (SEM_WAIT2 and SEM_WAKE2) to implement these semantics. The older operations are still supported under the COMPAT_FREEBSD9/10 options. The POSIX semaphore API in libc has been updated to use the new implementation. Note that the new implementation is not compatible with the previous implementation. However, this only affects static binaries (which cannot be helped by symbol versioning). Binaries using a dynamic libc will continue to work fine. SEM_MAGIC has been bumped so that mismatched binaries will error rather than corrupting a shared semaphore. In addition, a padding field has been added to sem_t so that it remains the same size.

Add new mmap(2) flags to permit applications to request specific virtual address alignment of mappings. - MAP_ALIGNED(n) requests a mapping aligned on a boundary of (1 << n). Requests for n >= number of bits in a pointer or less than the size of a page fail with EINVAL. This matches the API provided by NetBSD. - MAP_ALIGNED_SUPER is a special case of MAP_ALIGNED. It can be used to optimize the chances of using large pages. By default it will align the mapping on a large page boundary (the system is free to choose any large page size to align to that seems best for the mapping request). However, if the object being mapped is already using large pages, then it will align the virtual mapping to match the existing large pages in the object instead. - Internally, VMFS_ALIGNED_SPACE is now renamed to VMFS_SUPER_SPACE, and VMFS_ALIGNED_SPACE(n) is repurposed for specifying a specific alignment. MAP_ALIGNED(n) maps to using VMFS_ALIGNED_SPACE(n), while MAP_ALIGNED_SUPER maps to VMFS_SUPER_SPACE. - mmap() of a device object now uses VMFS_OPTIMAL_SPACE rather than explicitly using VMFS_SUPER_SPACE. All device objects are forced to use a specific color on creation, so VMFS_OPTIMAL_SPACE is effectively equivalent.

Fix handling of Quad-type arguments. Previously, syscalls containing 64-bit arguments would have explicit padding. On 64-bit platforms there was no padding, so the dummy argument was not covering anything. On 32-bit platforms with weak alignment (i.e. i386) the 64-bit argument did not need to be aligned, so there too an aditional argument was introduced. On 32-bit platforms with strong alignment (i.e. PowerPC) the dummy argument in fact cover the padding. By elimininating the dummy argument, 64-bit platforms now have 1 argument less. This also applies to 32-bit platforms with weak alignment. On PowerPC this doesn't matter, because the padding is still there. We just don't "name" it. Deal with those 3 cases.

Add a -s flag for the same functionality as strace. Introduce a Name type which is a String type that has no -s limitations applied to it. Change most Strings in the code to Names and add a few extra syscalls, namely munmap, read, rename and symlink. This was enough to facilitate following file descriptor allocations in the code more easily and getting a hint at what's being read/written from/to files. More syscalls should really be added.
While here, fix an off-by-one bug in the buffer truncation code and add a fflush so that truss's output reflects the syscall that the program is stuck in.

Fix Quad handling on 64-bit architectures. On 64-bit machines, a Quad also occupies a single slot. There's no need for any special handling of Quads. While here, remove the silly make_quad() function. We have the 2 longs on 32-bit machines already lined up in the argument array, so we can fetch the Quad with a simple cast.
Before: lseek(1,0x123456789,0xd0d0d0d0d0d0d0d0) = 4886718345 (0x123456789) After: lseek(1,0x123456789,SEEK_SET) = 4886718345 (0x123456789)

This is based on Dan's patch from the PR but I've hacked it for style and some other issues. While Dan has checked this patch, any goofs are probably my fault.
(The PR also contains support for the dual return values of pipe(). These will follow once I've ported that support to platforms other than i386.)

Do not ignore any possible errors that fseeko() may have. The fact is that fseeko() fails in very predictable and frequent ways on ia64. This is because the offset is actually an address in the process' address space, which on ia64 can be larger than long (for lseek) or off_t (for fseeko). The crux is the signedness. The register stack and memory stack are in region 4 on ia64. This means that the sign bit is 1. The large positive virtual address is wrongly interpreted as a negative file offset.
There's no quick fix. Even if you get around the API by using a SEEK_SET up to LONG_MAX and follow it up with a SEEK_CUR for the remainder, the kernel simply cannot deal with it. and the second seek will just fail.
Therefore, this change does not actually fix the root cause. It just makes sure we're not spitting out all kinds of garbage or that the get_struct() function in particular does not cause truss(1) to exit. This, I might add, invariably happened way too soon for truss(1) to be of any use on ia64...

Port truss(1) to 64-bit architectures: o Syscall return values do not fit in int on 64-bit architectures. Change the type of retval in <arch>_syscall_exit() to long and change the prototype of said function to return a long as well. o Change the prototype of print_syscall_ret() to take a long for the return address and change the format string accordingly. o Replace the code sequence tmp = malloc(X); sprintf(tmp, format, ...); with X by definition too small on 64-bit platforms by asprintf(&tmp, format, ...);
With these changes the output makes sense again, although it does mess up the tabulation on ia64. Go widescreen...
