3.5.0

• b584ca3 Fixed an issue running setup.py on ARM
• #822 Enabled relative leaks with MemLeak
  • This should be useful for e.g. heap-relative leaks
• #832 Changed all internal imports to use absolute imports (no functional changes)
• a12d0b6 Move STDOUT, PIPE, PTY constants to globals
  • process(..., stdin=process.PTY) --> process(..., stdin=PTY)
• #828 Use PR_SET_PTRACER for all process() and ssh.process() instances
  • This simplifies debugging on systems with YAMA ptrace enabled
• Various documentation enhancements
  • In particular, the gdb, elf, and ssh docs are much better
• #833 Performance enhancements for adb module
• d0267f3 packing.fit() now treats large offsets as cyclic patterns (e.g. 0x61616161 behaves the same as "aaaa")
• #835 Added ssh.checksec
  • Reports the kernel version and other relevant information on connection
• #857 Slightly shortened execve shellcode
• 300f8e0 Slightly speed up processing of large ELF files
• #861 Adds support for extracting IKCONFIG configs from Linux kernel images, and extends checksec to report on any insecure configurations discovered
• #871 Moves all of the basic syscall templates to shellcraft/common and exposes them via symlinks. Closed #685
  • Should not have any visible effects from any documented APIs
  • shellcraft.arch.os.syscall_function() still works the same
  • We now have the ability to differentiate between the connect syscall, and a TCP connect helper
• #887 sh_string now returns a quoted empty string '' rather than just an empty string
• #839 Exposes a huge amount of functionality via corefiles which was not previously availble. See the docs for examples.
  • process().corefile will automatically instantiate a Corefile for the process
  • QEMU-emulated processes are supported
  • Native processes are supported, including extraction of coredumps from apport crash logs
  • Native processes can be dumped while running, in a manner similar to GDB's gcore script
• #875 Added documentation (and tests) for AArch64 shellcode
• #882 The ROP class now respects context.bytes instead of using the hard-coded value of 4 (fixed #879)
• #869 Added several fields to the process class (uid, gid, suid, sgid) which are recorded at execution time, based on the file permissions
• #868 Changed the way that ssh.process() works internally, and it now returns a more specialized class, ssh_process.
  • Added ssh_process.corefile for fetching remote corefiles
  • Added ssh_process.ELF for getting an ELF of the remote executable
  • The uid, gid, and suid, and sgid which are recorded at execution time, based on the file permissions
• #865 Fixes ELF.read to support contiguous memory reads across non-contiguous file-backed segments
• #862 Adds a symlink= argument to ssh.set_working_directory, which will automatically symlink all of the files in the "old" working directory into the "new" working directory
