[(NEED_DL_SYSINFO || NEED_DL_SYSINFO_DSO) && SHARED]: Scan GLRO(dl_sysinfo_map) for PT_NOTE giving Linux kernel version, we can skip the uname call if it's there. * sysdeps/generic/dl-sysdep.c (_dl_sysdep_start): Don't use DL_SYSDEP_OSCHECK here. * elf/rtld.c (dl_main) [DL_SYSDEP_OSCHECK]: Do it here instead. * sysdeps/generic/ldsodefs.h (struct rtld_global_ro): Add _dl_sysinfo_map. * elf/rtld.c (dl_main): Don't call _dl_init_paths early in the rtld_is_main case. Call it unconditionally later. Move GLRO(dl_sysinfo_dso) handling earlier, before _dl_init_paths call. Initialize GLRO(dl_sysinfo_map). * elf/dl-load.c (open_path): Bail out if _dl_init_paths wasn't called. * sysdeps/generic/dl-sysdep.c (_DL_FIRST_EXTRA): New macro. (_dl_important_hwcaps) [(NEED_DL_SYSINFO || NEED_DL_SYSINFO_DSO) && SHARED]: Scan GLRO(dl_sysinfo_map) for PT_NOTE giving synthetic hwcap names and bit values. * elf/ldconfig.c (_DL_FIRST_EXTRA): New macro. (hwcap_extra): New static variable. (is_hwcap_platform): Check hwcap_extra for a matching name. Remove tls special case. (path_hwcap): Likewise. (parse_conf): Parse "hwcap" directive to define synthetic hwcap bits and their names, stored in hwcap_extra. (main) [USE_TLS]: Initialize final synthetic hwcap bit as "tls". * sysdeps/generic/ldsodefs.h (struct rtld_global_ro): Use uint64_t for _dl_hwcap and _dl_hwcap_mask. * sysdeps/generic/dl-sysdep.c (_dl_sysdep_start): Cast a_val for AT_HWCAP to unsigned long int. * elf/dl-support.c (_dl_aux_init): Likewise. (_dl_hwcap): Update defn. * elf/cache.c (print_entry): Pad hwcap value with 0s in diagnostic. * elf/ldconfig.c (search_dir): Likewise. |
