From 6eec482f47a8e8888132b05575dea352187278cb Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Thu, 4 Oct 2012 17:13:42 -0700 Subject: binfmt_elf: Uninitialized variable load_elf_interp() has interp_map_addr carefully described as "uninitialized_var" and marked so as to avoid a warning. However if you trace the code it is passed into load_elf_interp and then this value is checked against NULL. As this return value isn't used this is actually safe but it freaks various analysis tools that see un-initialized memory addresses being read before their value is ever defined. Set it to NULL as a matter of programming good taste if nothing else Signed-off-by: Alan Cox Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- fs/binfmt_elf.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'fs/binfmt_elf.c') diff --git a/fs/binfmt_elf.c b/fs/binfmt_elf.c index 0225fddf49b..7ef5f9fe272 100644 --- a/fs/binfmt_elf.c +++ b/fs/binfmt_elf.c @@ -881,7 +881,7 @@ static int load_elf_binary(struct linux_binprm *bprm, struct pt_regs *regs) } if (elf_interpreter) { - unsigned long uninitialized_var(interp_map_addr); + unsigned long interp_map_addr = 0; elf_entry = load_elf_interp(&loc->interp_elf_ex, interpreter, -- cgit v1.2.3
