Hi all,
I am happy to announced that libhugetlbfs 1.2-pre1 has been released to
the eagerly awaiting world. It can be found at the normal places (the
current dev snapshot at http://libhugetlbfs.ozlabs.org/, for instance,
or the git tree).
Highlights:
- Cleaned up abort()s during remapping to be more reliable.
- IA64 and sparc64 support for MORECORE and the tests.
- Reworked PLT detection which should be less fragile (and doesn't
conflict with segment attributes (the .plt is NOBITS on ppc64 per the
ABI, but we were putting a LONG(0) there)).
- EH_FRAME handling in the linker scripts, which fixes some binaries
that would try to error out, but would segfault (or otherwise die
awkwardly) when relinked.
- Add extra debugging to help with binaries with total segment size
close to the address space limit (typically 32-bit binaries).
Activated by HUGETLB_DEBUG=1, the messages may help when the kernel
says "hugetlb_get_unmapped_area() unable to open enough areas".
- Partial segment remapping allows normal binaries to attempt to
leverage segment remapping without relinking. This is achieved via an
LD_PRELOAD similar to morecore, along with two environmental variables
(one enables the feature, the other indicates where __executable_start
is). See the HOWTO for details.
- Cleanups all over the place.
Shortlog and Changelog follow.
Thanks,
Nish
