From 1a3a58fd763828c347baa92c378e2498efc12a9e Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Wed, 22 Nov 1995 10:00:23 +0000 Subject: Tue Nov 21 14:12:13 1995 Roland McGrath * malloc/malloc.c (align): Don't check contiguity and call abort. * hurd/hurdsig.c (post_reply): Function removed. (abort_thread, abort_all_rpcs, _hurdsig_abort_rpcs): Don't call it. Take single callback fn arg instead of reply port and type. (_hurd_internal_post_signal): Callers changed. Cache reply stub fn ptr in local var before UNTRACED might be changed. * sysdeps/mach/hurd/mmap.c: Cope with a null write memobj for PROT_READ|PROT_WRITE copy mapping. Pass a proper vm_inherit_t to vm_map. * elf/rtld.c (_dl_start): For --list, do output and exit before relocating. --- elf/rtld.c | 57 ++++++++++++++++++++++++++++----------------------------- 1 file changed, 28 insertions(+), 29 deletions(-) (limited to 'elf') diff --git a/elf/rtld.c b/elf/rtld.c index d0c25b4db4..cf9517d527 100644 --- a/elf/rtld.c +++ b/elf/rtld.c @@ -130,7 +130,6 @@ dl_main (const Elf32_Phdr *phdr, const char *interpreter_name; int lazy; int list_only = 0; - __typeof (_exit) *volatile exitfn; if (*user_entry == (Elf32_Addr) &_start) { @@ -294,12 +293,35 @@ of this helper program; chances are you did not intend to run this program.\n", rtld_map.l_next->l_prev = &rtld_map; } - lazy = !_dl_secure && *(getenv ("LD_BIND_NOW") ?: "") == '\0'; + if (list_only) + { + /* We were run just to list the shared libraries.
