X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=750a1c253f81a9dfe2cef5a568c68a5838ab46b9;p=thirdparty%2Fglibc.git [RISC-V] Fix parsing flags in ELF64 files. When ldconfig reads Elf64 files to determine the ABI, it used the Elf32 type, so read the wrong location, and stored the wrong ABI type in the cache, making the cache useless. This patch uses an Elf64 type for Elf64 objects instead. Note that pre-patch caches might need to be manually removed and regenerated to get the correct ABIs stored. [BZ #22827] * sysdeps/unix/sysv/linux/riscv/readelflib.c (process_elf_file): Use 64-bit ELF type for 64-bit ELF objects.
