From 2a7e0775d0b0dfc083f97c72dc885f6dab8dd27b Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 22 Oct 2012 16:09:05 +0200 Subject: Blackfin: Annotate strnlen_user and strlen_user 'src' parameter with __user The 'src' parameter of strnlen_user and strlen_user is supposed to take a userspace pointer, so annotate it with __user. This fixes the following and similar sparse warnings: fs/binfmt_elf_fdpic.c:671:36: warning: incorrect type in argument 1 (different address spaces) fs/binfmt_elf_fdpic.c:671:36: expected char const *src fs/binfmt_elf_fdpic.c:671:36: got char [noderef] *[assigned] p fs/binfmt_elf_fdpic.c:683:36: warning: incorrect type in argument 1 (different address spaces) fs/binfmt_elf_fdpic.c:683:36: expected char const *src fs/binfmt_elf_fdpic.c:683:36: got char [noderef] *[assigned] p Signed-off-by: Lars-Peter Clausen Signed-off-by: Bob Liu --- arch/blackfin/include/asm/uaccess.h | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) (limited to 'arch/blackfin') diff --git a/arch/blackfin/include/asm/uaccess.h b/arch/blackfin/include/asm/uaccess.h index ded2d05847f..3ee7b421615 100644 --- a/arch/blackfin/include/asm/uaccess.h +++ b/arch/blackfin/include/asm/uaccess.h @@ -237,18 +237,18 @@ strncpy_from_user(char *dst, const char __user *src, long count) * On exception, returns 0. * If the string is too long, returns a value greater than n. */ -static inline long __must_check strnlen_user(const char *src, long n) +static inline long __must_check strnlen_user(const char __user *src, long n) { if (!access_ok(VERIFY_READ, src, 1)) return 0; - return strnlen(src, n) + 1; + return strnlen((const char __force *)src, n) + 1; } -static inline long __must_check strlen_user(const char *src) +static inline long __must_check strlen_user(const char __user *src) { if (!access_ok(VERIFY_READ, src, 1)) return 0; - return strlen(src) + 1; + return strlen((const char __force *)src) + 1; } /* -- cgit v1.2.3-18-g5258
