ply-2.1.1

Changed

• Disable the kernel verifier output by default. Newer kernels
  generates massive amounts of verifier output for certain BPF
  programs. It expects to be able to store up to 16MB (!) of text. On
  some systems using ply, that is half of the total system
  RAM. Instead, the verifier output is now enabled by specifying the
  -d/--debug option.

Added

• Allow lossy tracing. By default ply will exit when it detects loss
  of any trace events. The new -k/--keep-going option allows the
  user to disable this safety check.
• ply can now be built against alternative libcs. In particular
  Glibc and musl are known to work.
• VPATH builds are now supported.
• Basic automatic test system. This ensures that basic ply can be
  built against all supported architectures and that basic probes work
  as expected.

Fixed

• When expanding wildcards in probe specifiers, avoid symbols that we
  know are untraceable.
• Symbol lookups (typically in stack traces) now always return the
  correct symbol.
• Multiple references to stack no longer results in a SIGSEGV.
• The type information from caller/retval is now retained in all
  cases.
