Stop after we've written the dump in response to the initial breakpoint
EXCEPTION_DEBUG_EVENT we recieve for attaching to the process.
(rather than bogusly sitting there for 20 seconds waiting for more debug
events from a stopped process after we've already written the dump).
Use the (undocumented) MEMORY_WORKING_SET_EX_INFORMATION in dumper to
determine if a MEM_IMAGE region is unsharable, and hence has been
modified.
After this, we will end up dumping memory regions where:
- state is MEM_COMMIT (i.e. is not MEM_RESERVE or MEM_FREE), and
-- type is MEM_PRIVATE and protection allows reads (i.e. not a guardpage), or
-- type is MEM_IMAGE and attribute is non-sharable (i.e. it was WC, got
written to, and is now a RW copy)
After this, we will end up dumping memory regions where:
- state is MEM_COMMIT (i.e. is not MEM_RESERVE or MEM_FREE), and
-- type is MEM_PRIVATE and protection allows reads (i.e. not a guardpage), or
-- type is MEM_IMAGE and protection allows writes
Making this decision based on the current protection isn't 100% correct,
because it may have been changed using VirtualProtect(). But we don't
know how to determine if a region is shareable.
(As a practical matter, anything which gets us the stack (MEM_PRIVATE)
and .data/.bss (RW MEM_IMAGE) is going to be enough for 99% of cases)
Update dumper for bfd API changes in binutils 2.34
libbfd doesn't guarantee API stability, so we've just been lucky this
hasn't broken more often.
See binutils commit fd361982.
Bump GPLv2+ to GPLv3+ for some files, clarify BSD 2-clause.
Everything else stays under GPLv3+.
New Linking Exception exempts resulting executables from LGPLv3 section 4.
