glibc: remove unnecessary pushq/popq so that shim_clone can run without segv.
This is a preparation for later patch to clean up shim_clone() to
remove glibc modification.
libos: Currently child thread ret ip is taken from new child stack.
But it can be retrieved from parent's thread context, so such a hack
isn't needed.
Now the modification to clone.S is not needed anymore. So remove it.
_dl_debug_state has hidden visibility, so there is no risk in using it
with Pal. We can remove the modification to glibc and rename
__libc_dl_debug_state back to _dl_debug_state.
- Fix a severe bug caused by merging #87. The patch does not check the return values from get_config_entries_size(), while the return values can easily be negative (-PAL_ERROR_INVAL). Any usage of this function should carefully check the return values and also pass the size into get_config_entries() to prevent buffer overflow.
- Fix a minor bug in handling IPC disconnection. The callback ipc_child_exit() never receives a "term_signal" parameter. The callback is called when thepipe to a child process unexpectedly terminates, which can only mean the child process has crashed. I believe the proper signal to send is SIGKILL.
- Remove a compilation warning caused by type mismatch of __malloc().
- Allow binding TCP socket to ANY address
- enable LD_PRELOAD in glibc
- disable output buffering in LTP tests to reveal omitted passes
- Remove a double-unlock in shim_async.c
- Replace all int with size_t or ssize_t in Graphene configuration API
- Add new passed LTP tests
- Bugfixes in PAL and SHIM
- Improvement of migration scheme in SHIM, which largely speed up
forking
- Upgrade glibc to 2.19
- FreeBSD port
- Support OpenJDK, python and R
