runtime backtrace: stop infinite loops by checking for full print buffer
2008-04-13 Frank Ch. Eigler <fche@elastic.org>
* print.c (_stp_pbuf_full): New function to note full print buffer.
* stack-{i386,x86_64}.c: Use it in all stack-searching loops, to
impose another limit against unbounded iteration.
* commit 'origin/unwind':
Fixes for 2.6.25 pt_regs changes.
Include string.h
Change stap to get kernel symbols from debuginfo and
reincarnate vim/ directory in this branch to match master
Add new define STP_USE_DWARF_UNWINDER which is set based on which archs
Remove misleading error message.
Support for kernels built with CONFIG_FRAME_POINTER
Fix regression.
dded _stp_read_address() and changed code to use it.
kretprobe trampoline fixes
i386 fixes.
control.c (_stp_ctl_write_dbug): Insert missing break.
32-bit fixes
Cleanup.
