854988bc5f Detect AlreadyPacked even when trailing PackHeader has been lopped. 
This is heuristic, but strong.

320e5b850f all: yet more cleanups 
Changes include:
  - use standard names for PE constants
  - add some more "noexcept"
  - improve upx_is_integral type-trait
  - introduce is_same_all and is_same_any type-traits
  - prepare TE-size checks in packer.h
  - CI updates

adb0ca8250 Many changes for ELF shared libraries on Linux and Android 
Handling more than 2 PT_LOAD (and thus more than 1 executable PT_LOAD)
required extensive changes.  But the bonus is the infrastructure
to support a different (de-)compression algorithm for each PT_LOAD.

16de3e78a5 src: try to fix canUnpack() confusion - see packer.h 2022-11-10 06:00:53 +01:00
John Reiser
82ed25bb44 Major fix 64-bit un_shlib_1() and unpack(), but not --android-shlib 
Also canUnpack() is really a 'bool' which sets overlay_offset
when 'true'; confusing!

9e8de4abe5 i386: new stub strategy to avoid problems with early mmap layout 
The stub occupies the same region that execve() would create
for the original progam.  The stub copies everything to a new area,
erases the original region, replaces it with the de-compressed
program, and erases the copy of itself via the escape hatch.
The copy is inexpensive via mmap() of /proc/self/exe.
