Revert "x86_64: unbreak test-ptrace" This reverts commit c9c5a40be19f8159aff0f5f07b753d59ba65f0f9. dwarf_get() returns 0 on success. We should continue unwinding in that case. TBD: investigate test-ptrace failure on some platforms.

x86_64: unbreak test-ptrace If dwarf_get returns 0 (indicating the end of call chain), we should not override the return value to 1. This may result in the caller continuing to unwind and getting spurious errors.

freebsd: Fix boundary conditions for non-dwarf walker on x86_64. In the commit d04dc94cc2b0141f06ed9de1665ab89a3f549e0b, the check for dwarf.ip == 0 was removed from non-dwarf walker in x86_64 version of unw_step(). Apparently this broke the detection of the end of frame chain when NULL %rbp is specified, because the case just marked dwarf.ip as 0. Explicitly set ret to 0 to indicate the end of iteration.

Fast back-trace for x86_64 for only collecting the call stack. Adds new function to perform a pure stack walk without unwinding, functionally similar to backtrace() but accelerated by an address attribute cache the caller maintains across calls.

[X86-64] For local unwinding, we have a defence mechanism against bad/missing unwind information, which could result in libunwind dereferencing bad pointers. This mechanism is based on msync(2) system call and significantly reduces the chances of a bad pointer dereference in libunwind. The original idea was to turn this mechanism on only when necessary i.e. libunwind didn't find proper unwind information for a IP. There are a couple of problems in the current implementation. * The flag is global and is modified without locking * The flag isn't reset when starting a new unwind The attached patch makes ->validate a per-thread setting by moving it into struct cursor from unw_local_addr_space and resets it to false when starting a new unwind. As a result, cursor->as_arg points to the cursor itself instead of the ucontext (for the local case). This was found to reduce the number of msync() system calls from an application using libunwind significantly.

[x86-64] (unw_step): Further refine handling of functions without unwind-info. CFA should be incremented by 16 in the hope that the previous frame may have valid unwind info. Also increase the default frame pointer recognition heuristic from 4k to 16k. Signed-off-by: Andrey Veskov <Andrey.Veskov@intel.com> Signed-off-by: Arun Sharma <arun.sharma@google.com>

[x86-64] (unw_step): Improve handling of functions which lack unwind info. If following the frame-chain leads to a frame >= 4KB away, we conclude that the frame-pointer isn't really valid.

(unw_step): If dwarf_step() fails and the frame doesn't look like a signal-trampoline, assume that it's a PLT stub. If non-DWARF stepping fails to change IP and CFA, declare it a bad frame. 2004/11/23 16:59:56-08:00 mostang.com!davidm (unw_step): Also print IP as part of the function-trace. 2004/11/23 16:17:37-08:00 mostang.com!davidm (unw_step): When dwarf_step() fails on a signal-frame, fill in all the known locations because dwarf_step() fails on older kernels which don't export the kernel vDSO even though every- thing else may be providing proper DWARF unwind-info. 2004/10/25 17:43:57+02:00 homeip.net!davidm Add Debug statement for return-value.

(unw_step): If dwarf_step() fails, fall back on using the frame-chain. In theory, this may not be needed. In practice, I find that Red Hat Enterprise Linux AS release 3, the _start() routine has no unwind-info, but we need to be able to unwind into this routine to find the end-of-frame-chain marker (RBP == 0).
