From f6870d6b4f32c99fdbf4367422820218b2f638bb Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Thu, 28 Jun 2018 12:07:51 -0400 Subject: make dladdr consistently produce the first symbol in presence of aliases the early-exit condition for the symbol match loop on exact matches caused dladdr to produce the first match for an exact match, but the last match for an inexact match. in the interest of consistency, require a strictly-closer match to replace an already-found one. --- ldso/dynlink.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'ldso') diff --git a/ldso/dynlink.c b/ldso/dynlink.c index d963aeab..a773b782 100644 --- a/ldso/dynlink.c +++ b/ldso/dynlink.c @@ -1978,7 +1978,7 @@ int dladdr(const void *addr_arg, Dl_info *info) && (1<<(sym->st_info&0xf) & OK_TYPES) && (1<<(sym->st_info>>4) & OK_BINDS)) { size_t symaddr = (size_t)laddr(p, sym->st_value); - if (symaddr > addr || symaddr < best) + if (symaddr > addr || symaddr <= best) continue; best = symaddr; bestsym = sym; -- cgit v1.2.1
