John Reiser 51536a7acd decompression PackLinuxElf32x86.ET_DYN 2006-05-23 17:42:35 -07:00
John Reiser d2718e99a4 Change class PackLinuxI386elf : public PackLinuxI386
into   class PackLinuxElf32x86 : public PackLinuxElf32Le : public PackLinuxElf32
which makes the code for compressing ELF (for direct-to-memory decompression)
cleaner because ELF has some of the class tree to itself.
This assumes PROT_EXEC|PROT_WRITE ought to work.
This is checked at runtime, and if it fails then
give a message on stderr and exit(127).

Modify --force-execve so that runtime avoids PROT_EXEC|PROT_WRITE.
Then executables compressed with --force-execve will run under
PaX, grSecurity, and strict SELinux.

John Reiser 268e322e1c Extra parameter for compressWithFilters and packExtent,
to fix 2-pass problem with --brute on linux/elf386.
Only one decompression method is allowed, chosen by
smallest output for .text; but Elf headers come first.

John Reiser 664a82e7c9 Start re-organizing the packing of Elf, by making Elf32 come first,
with Big endian and Little endian derived from it.
I386 still uses the old way, but PowerPC (both Linux and Darwin [Mac])
use the new way.
