commit 7ba91d2256d2834b7d92e510782b8f7543daf678 Author: Matheus Castanho <msc@linux.ibm.com> Date: Thu Aug 12 16:38:46 2021 -0300 Disable hugepage-backed malloc if __morecore is not available Starting with glibc 2.32, __morecore hook has been marked as deprecated, and was completely removed on glibc 2.34, which causes an undefined symbol error during the build of libhugetlbfs. Greater changes are needed in order to keep providing the same functionality with future versions of glibc (see issue #52). Meanwhile, we can disable hugepage-backed malloc setup if __morecore is not available so users can at least keep using the other features provided by the library. Related tests are also conditionally disabled, and will show as SKIPPED if __morecore is not available. Tested on powerpc64le and x86_64 with glibc 2.34 and olders. Signed-off-by: Matheus Castanho <msc@linux.ibm.com> Tested-by: Breno Leitao <leitao@debian.org> an23 glibc 版本为 2.36，__morecore 已经被完全移除，本bugzilla 里 FAIL 的用例都是因为使用了 hugepage-backed malloc。使用了 2.2.4 版本的 libhugetlbfs，本bugzilla FAIL 用例均为 SKIPPED 或 PASS LD_PRELOAD=libhugetlbfs.so HUGETLB_MORECORE=yes malloc (2M: 64): SKIPPED LD_PRELOAD=libhugetlbfs.so HUGETLB_MORECORE=yes HUGETLB_RESTRICT_EXE=unknown:none malloc (2M: 64): SKIPPED LD_PRELOAD=libhugetlbfs.so HUGETLB_MORECORE=yes HUGETLB_RESTRICT_EXE=unknown:malloc malloc (2M: 64): SKIPPED LD_PRELOAD=libhugetlbfs.so HUGETLB_MORECORE=yes malloc_manysmall (2M: 64): SKIPPED GLIBC_TUNABLES=glibc.malloc.tcache_count=0 LD_PRELOAD=libhugetlbfs.so HUGETLB_MORECORE=yes heapshrink (2M: 64): SKIPPED GLIBC_TUNABLES=glibc.malloc.tcache_count=0 LD_PRELOAD=libheapshrink.so HUGETLB_MORECORE=yes HUGETLB_MORECORE_SHRINK=yes heapshrink (2M: 64): SKIPPED shmoverride_linked (2M: 64): PASS HUGETLB_SHM=yes shmoverride_linked (2M: 64): PASS 建议在 an23 上用新版本 libhugetlbfs 进行测试 测试用例问题，置为invalid
测试记录一下，后续23.1 的版本更新libhugetlbfs的版本。
