The code correctly took the previous row's line number entry, but incorrectly took the current row's file name entry. Notably, this caused DDB to report the wrong file names for inlined calls to functions defined in header files. ok mlarkin

For this to work, it requires using a new version of boot(8), and
booting a kernel with the .debug_line section present (e.g., building
with ``makeoptions DEBUG=-g'' and then booting the bsd.gdb kernel
instead of the stripped bsd kernel).
Still a WIP, but no failure reports yet. Committing so further
development and testing can happen in tree.

According to POSIX, SIGSEGV should specify SEGV_ACCERR if the memory pages are mapped, but the protections don't match the user's access attempts, while SEGV_MAPERR should only be specified for pages that are unmapped. Some platforms currently handle this correctly, but not all. Additionally, SIGBUS/BUS_ADRERR should be generated instead of SIGSEGV for access to file mapped pages that exceed the end of the file.

To avoid this, we take advantage of ELF weak symbol semantics, and insert a call to an empty, weakly named function. The semantics of calling this function aren't determinable until load time, so the compiler and linker need to keep the memset() call. There are still ways a toolchain might defeat this trick (e.g., optimistically expecting the weak symbol to not be overloaded, and only calling memset() if it is; promoting weak symbols to strong symbols at link-time when emitting a static binary because they won't be interposed; implementing load-time optimizations). But at least for the foreseeable future, these seem unlikely. ok deraadt

Log message:
Fix vnode leak in systrace(4).
If a user calls STRIOCGETCWD two or more times in a row without an
intervening STRIOCRESCWD, then the references held on fst-fd_{c,r}dir
