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. MFC after: 1 week

Add support for decoding Timespec, Timeval, Itimerval, Pollfd, Fd_set and Sigaction structures. Use these for printing the arguments to sigaction(), nanosleep(), select(), poll(), gettimeofday(), clock_gettime(), recvfrom(), getitimer() and setitimer(). 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.)

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.

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.

Add support for decoding Timespec, Timeval, Itimerval, Pollfd, Fd_set and Sigaction structures. Use these for printing the arguments to sigaction(), nanosleep(), select(), poll(), gettimeofday(), clock_gettime(), recvfrom(), getitimer() and setitimer(). 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.)

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... Not tested on: alpha, sparc64.

Add support for decoding Timespec, Timeval, Itimerval, Pollfd, Fd_set and Sigaction structures. Use these for printing the arguments to sigaction(), nanosleep(), select(), poll(), gettimeofday(), clock_gettime(), recvfrom(), getitimer() and setitimer(). 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.)

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.
