MFC 295930: Add support for displaying thread IDs to truss(1).
- Consolidate duplicate code for printing the metadata at the start of each line into a shared function. - Add an -H option which will log the thread ID of the relevant thread for each event.
While here, remove some extraneous calls to clock_gettime() in print_syscall() and print_syscall_ret(). The caller of print_syscall_ret() always updates the current thread's "after" time before it is called. |

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.
271389: Stop accessing the saved stack pointer by looking past the end of the array of registers.
286330: Whitespace fix: remove some spurious spaces before commas.
286331: 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.
286358: Add recently added values of various flags and enumerations including kevent filters, kevent flags, flags to mmap, seek locations, fcntl operations, file flags, socket domains, open flags, resource limits, and pathconf values.
286378: Don't mark the fcntl flag argument as an output parameter so that it is always decoded. Previously the argument was not decoded if fcntl() failed.
286380: Decode the arguments to mkfifo() and fix an off-by-one error in the arguments to mknod().
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 when pretty-printing structures. Most structures used both spaces, but some only used a trailing space and some used neither.
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 sigprocmask operation type.
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 the final summary is shown. This is especially noticeable when there is not much output from the application being traced. |

Extend the support for exempting processes from being killed when swap is exhausted. - Add a new protect(1) command that can be used to set or revoke protection from arbitrary processes. Similar to ktrace it can apply a change to all existing descendants of a process as well as future descendants. - Add a new procctl(2) system call that provides a generic interface for control operations on processes (as opposed to the debugger-specific operations provided by ptrace(2)). procctl(2) uses a combination of idtype_t and an id to identify the set of processes on which to operate similar to wait6(). - Add a PROC_SPROTECT control operation to manage the protection status of a set of processes. MADV_PROTECT still works for backwards compatability. - Add a p_flag2 to struct proc (and a corresponding ki_flag2 to kinfo_proc) the first bit of which is used to track if P_PROTECT should be inherited by new child processes.

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 detaching under some circumstances.
When truss is detaching from very active process it is possible to hang on waitpid(2) in restore_proc() forever, because ptrace(PT_SYSCALL) must be called before detaching, to allow the debugging process to continue execution. Also when truss called with '-c' argument, it does not print anything after detach, because it immediately exits from restore_proc().
To fix these two problems make detaching deferred, but then it is impossible to detach from a process which does not do any system call. To fix this issue use sigaction(2) instead of signal(3) to disable SA_RESTART flag for waitpid(2) that makes it non-restartable. Remove global variable child_pid, because now detaching is handled in context where child's pid is known.

It turns out that truss also used kdump's mkioctls script, and expected ioctlname() to return a pointer to the name rather than print it. This did not show up in testing because truss had its own prototype for ioctlname(), so it would build fine and run fine as long as the program being traced did not issue an ioctl.
Teach mkioctls to generate different versions of ioctlname() based on its first command-line argument.

Normally, when a header file is removed from the build (as i4b headers were recently), a simple 'make cleandepend; make depend' is sufficient to keep the tree buildable after a cvs update when doing incremental builds.
However, kdump and truss use a script which searches for header files that define ioctls, and generates C code that includes them. This script will usually not need updating when a header file is removed, so the normal dependency mechanism will not realize that it needs to be re-run. One is therefore left with code that references dead files but will only be removed by a full 'make clean', which defeats the purpose of incremental builds.
To work around this, modify the cleandepend target in bsd.dep.mk to also remove any files listed in a new variable named CLEANDEPFILES, and modify kdump's and truss's Makefiles accordingly.

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.

So get rid of SIGQUIT extra hack and limit coredumpsize to zero instead.
Tested: still works, correct signal reported. No more codedumps from SIGSEGV in the trussed proces. This file compiles cleanly on AMD64 (sledge).

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...

Fix truss on ia64. The syscall arguments are written to the trap frame, occupying scratch registers r16 and up. We don't have to save any scratch registers for syscalls, so we have plenty of room there. Consequently, when we fetch the registers from the process, we automaticly have all the arguments and don't need to read them seperately.

Revamp of the syscall path, exception and context handling. The prime objectives are: o Implement a syscall path based on the epc inststruction (see sys/ia64/ia64/syscall.s). o Revisit the places were we need to save and restore registers and define those contexts in terms of the register sets (see sys/ia64/include/_regset.h).
Secundairy objectives: o Remove the requirement to use contigmalloc for kernel stacks. o Better handling of the high FP registers for SMP systems. o Switch to the new cpu_switch() and cpu_throw() semantics. o Add a good unwinder to reconstruct contexts for the rare cases we need to (see sys/contrib/ia64/libuwx)
Many files are affected by this change. Functionally it boils down to: o The EPC syscall doesn't preserve registers it does not need to preserve and places the arguments differently on the stack. This affects libc and truss. o The address of the kernel page directory (kptdir) had to be unstaticized for use by the nested TLB fault handler. The name has been changed to ia64_kptdir to avoid conflicts. The renaming affects libkvm. o The trapframe only contains the special registers and the scratch registers. For syscalls using the EPC syscall path no scratch registers are saved. This affects all places where the trapframe is accessed. Most notably the unaligned access handler, the signal delivery code and the debugger. o Context switching only partly saves the special registers and the preserved registers. This affects cpu_switch() and triggered the move to the new semantics, which additionally affects cpu_throw(). o The high FP registers are either in the PCB or on some CPU. context switching for them is done lazily. This affects trap(). o The mcontext has room for all registers, but not all of them have to be defined in all cases. This mostly affects signal delivery code now. The *context syscalls are as of yet still unimplemented.
Many details went into the removal of the requirement to use contigmalloc for kernel stacks. The details are mostly CPU specific and limited to exception_save() and exception_restore(). The few places where we create, destroy or switch stacks were mostly simplified by not having to construct physical addresses and additionally saving the virtual addresses for later use.
Besides more efficient context saving and restoring, which of course yields a noticable speedup, this also fixes the dreaded SMP bootup problem as a side-effect. The details of which are still not fully understood.
This change includes all the necessary backward compatibility code to have it handle older userland binaries that use the break instruction for syscalls. Support for break-based syscalls has been pessimized in favor of a clean implementation. Due to the overall better performance of the kernel, this will still be notived as an improvement if it's noticed at all.

Teach truss(1) to display sockaddrs. It currently knows about AF_INET, AF_INET6 and AF_UNIX sockaddrs, and will recognize accept(), bind(), connect(), getpeername() and getsockname() as syscalls taking sockaddr arguments. Some enterprising soul might want to add (and test) support for the send() / recv() family of syscalls as well.

In get_string(), 0-terminate the contents of buf ``just in case''; otherwise, if the very first fgetc() already yielded EOF, the returned string won't get terminated at all.

Handle the case where we truss an SUGID program -- in particular, we need to wake up any processes waiting via PIOCWAIT on process exit, and truss needs to be more aware that a process may actually disappear while it's waiting.

Some of these (mv, find, apply, xargs) might benefit greatly from being rewritten to use vfork() properly.

Proper way to do the previous mis-commit. Still not quite right, because some header files (e.g., <err.h>) include <machine/something.h>, and this will not pick up the right header files, so it may be removed eventually anyway. But some people who are not willing to build the right way apparantly want this, so this is for them.

Get rid of the bogus include -- it is incomplete (as it doesn't handle anything other than <sys/*.h>), and unnecessary in most cases. (The situations where it is necesary can be dealt with by manually-made symlinks, which is acceptable since they should only occur during testing. Remember: the tree does not compile well if you do not have matching header files installed. Half-baked -I directives don't cover enough of the cases.)

Change the ioctls for procfs around a bit; in particular, whever possible, change from
ioctl(fd, PIOC<foo>, &i);
to
ioctl(fd, PIOC<foo>, i);
This is going from the _IOW to _IO ioctl macro. The kernel, procctl, and truss must be in synch for it all to work (not doing so will get errors about inappropriate ioctl's, fortunately). Hopefully I didn't forget anything :).

Use the new PF_LINGER flag -- when this is set in a process' proc structure, said process will not have its event mask cleared (and be restarted) on the last close of a procfs/mem file for that pid. This reduces the chance that a truss-monitored process will be left hanging with these bits set and nobody looking for it.
This is the least-tested change of all of these, I'm afraid.
