Hi all,
I am pleased to announce that we have been the libhugetlbfs 1.3 release
process. From this point on, only bug-fixes, non-functional cleanups,
etc. will be accepted (so, for instance, Dean should still submit an
updated version of his morecore cleanup patch.) The tarball can be
obtained at
http://libhugetlbfs.ozlabs.org/releases/libhugetlbfs-1.3-pre1.tar.gz
Changes since 1.2:
Adam Litke (12):
Test hugetlb pool counter handling corner cases
Regression test for hugetlbfs quota management
elf64ppc.xB flexible BSS alignment
elflink: Always use dl_iterate_phdr to scan the program headers
elflink: Add const notation to a few functions
elflink: Integrate extra-copy in prepare_segment()
Extend 'counters' test case coverage
build: Rename .S files
elflink: Add powerpc64-specific PLT size detection
ldscripts: Remove unneeded __libhuge_filesz symbol
tests: Fix direct test
Partially revert "elflink: filter extracopy on GLIBC symbols"
Andrew Hastings (7):
morecore.c: rename "newsize"
morecore.c: heap shrinking
move some defines into libhugetlbfs_internal.h.
change tests to read /proc/meminfo
morecore.c: eliminate use of mlock()
icache-hygeine: fix misspelling of 'hygiene'
test_addr_huge(): change ERROR to verbose_printf
Dean Luick (1):
Add "[hostname:pid]" to output messages
Jon Tollefson (13):
tests: handle larger number of threads
tests: check for failure of malloc
handle larger page sizes
tests: Check if huge page size is valid
tests: verify that huge page size isn't too big for the test
icache-hygeine: Verify that huge page size is valid
ptrace-write-hugepage: missing config message
quota: Verify that huge page size is valid
tests: verify there are enough huge pages
counters: Verify huge page size is valid
morecore: offset needs to be long to handle larger page size
common check for gethugepagesize() return
check gethugepagesize() return
Nishanth Aravamudan (20):
ldscripts: standardize BDT phdr naming
linkhuge: FAIL if a segment is hugepage and shouldn't be
ldscripts: Place 32bit BDT PLT in BSS for PPC
counters: update to new sysctl
run_tests.sh: be smarter about using the overcommit sysctl
run_tests.sh: one more old sysctl reference
hugeutils: check for errors from strtol() in read_meminfo()
hugeutils: prevent overflow in gethugepagesize()
debug: make HUGETLB_DEBUG generic
libhugetlbfs: consolidate to one constructor
morecore: gethugepagesize() returns negative value on error
morecore: dump /proc/pid/maps when the heap is forced to move and DEBUG
elflink: filter extracopy on GLIBC symbols
elflink: emit symbol name when extracopy symbols are found
DEBUG overrides VERBOSE checks
counters: reset hugepage value properly
truncate_sigbus_versus_oom: clean-up justification
HOWTO: Add configuration information
tests: check uid/gid in tests where it matters
morecore: add HUGETLB_NO_PREFAULT
Steve Fox (4):
Scan entire BSS for non-zero data in DEBUG mode
elflink: Fork creation of hugetlbfs mappings.
elflink: Force extra_copy to begin immediately after filesz
elflink: Use correct start point for check_bss
