The regression python scripts are not marked executable. Also they
expect that the Makefile has setup the environment correctly so just
marking them executable would not be useful. So drop the unused shebang
to avoid encoding the interpreter in multiple places.
Script/regression.py is a library so it also doesn't need a shebang.
If the broadcast stream is not opened this most likely means that
there's no configured multicast route so add a helpful warning. Also no
point in trying to read/write from/to a non-existent stream.
Resolves#501.
* Fix a PAL unit test
* Make the PAL unit tests fail properly if one that should work doesn't.
* Get consistent indexes with and without graphene ipc module
* A little debugging output for ltp flakiness. Seems to make things a little more stable.
* A bugfix for issue #80. The migration is not complete when a file-backed VMA is larger than
the file size, but the file size is not page-aligned. In Linux, if the file size is smaller
than the mapped memory, accessing the remaining memory that is not backed by the file will
trigger a SIGBUS. However, it is fine to access the remaining memory within the last page that
still overlaps with file, and won't trigger a SIGBUS. This area is commonly used in ELF binary
to store uninitialized, static variables. To improve fork latency, Graphene chooses to
truncate the migration size as the file size, but missed the memory which belongs to the last
file-backed page. The migration size should be aligned up to the page size.
* Fix assertion lines in PAL and LibOS
* Make sure the return code is correct for the LTP script, bump up some timeouts
* Only run gipc tests when the module is loaded, for the purposes of getting CI to work.
* Build fix
Release of Graphene SGX:
Supporting native Linux application in Intel SGX enclaves.
Most applications are supported. Some features may still be buggy.
Improving portability of Graphene:
Eliminating GCC-ism of the host-generic code.
Easier to port to non-Posix platform (e.g., Windows without Cygwin).
Plenty of bugfixes for Linux kernel later than 3.5 and Ubuntu later than 10.10.
More organized code to improve portability.
Regression tests for Pal to test completeness of implementation.
