From b937534868c8d7aec3b6d645bf5fd657bbfccd42 Mon Sep 17 00:00:00 2001 From: Siddhesh Poyarekar Date: Wed, 29 May 2013 21:30:20 +0530 Subject: Avoid crashing in LD_DEBUG when program name is unavailable Resolves: #15465 The program name may be unavailable if the user application tampers with argc and argv[]. Some parts of the dynamic linker caters for this while others don't, so this patch consolidates the check and fallback into a single macro and updates all users. --- elf/dl-error.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'elf/dl-error.c') diff --git a/elf/dl-error.c b/elf/dl-error.c index 798784543b..8257c17030 100644 --- a/elf/dl-error.c +++ b/elf/dl-error.c @@ -119,7 +119,7 @@ _dl_signal_error (int errcode, const char *objname, const char *occation, /* Lossage while resolving the program's own symbols is always fatal. */ char buffer[1024]; _dl_fatal_printf ("%s: %s: %s%s%s%s%s\n", - rtld_progname ?: "", + RTLD_PROGNAME, occation ?: N_("error while loading shared libraries"), objname, *objname ?
