Harshit Mogalapalli 1316c28569 cifs: potential buffer overflow in handling symlinks ... [ Upstream commit 64c4a37ac0 ] Smatch printed a warning: arch/x86/crypto/poly1305_glue.c:198 poly1305_update_arch() error: __memcpy() 'dctx->buf' too small (16 vs u32max) It's caused because Smatch marks 'link_len' as untrusted since it comes from sscanf(). Add a check to ensure that 'link_len' is not larger than the size of the 'link_str' buffer.
