* Normally, when a header file is removed from the build (as i4b headersDag-Erling Smørgrav2008-02-031-2/+3
| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | 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.

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.

I was smart enough to not have it coredump on SIGQUIT but it didn't ocur to me SIGSEGV might cause a coredump, too :-) So get rid of SIGQUIT extra hack and limit coredumpsize to zero instead.

* Do not ignore any possible errors that fseeko() may have. The factMarcel Moolenaar2003-11-131-22/+24
| | | | | | | | | | | | | | | | | | | | | | | | 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... Notes: svn path=/head/; revision=122606
* Port truss(1) to 64-bit architectures:Marcel Moolenaar2003-11-0911-113/+84
| | | | | | | | | | | | | | | | | | | | | 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.
