Joakim Gebart 24d15ad9a5 core/net/ip: Prevent (tiny) buffer overflow in resolv_found() ... An off-by-one error in resolv_found() could make an strncat() call overflow by the terminating null byte. When building with Clang the following warning was shown: ../../../core/net/ip/resolv.c:1458:17: warning: the value of the size argument in 'strncat' is too large, might lead to a buffer overflow [-Wstrncat-size] sizeof(resolv_hostname) - strlen(resolv_hostname)); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ../../../core/net/ip/resolv.c:1458:17: note: change the argument to be the free space in the destination buffer minus the terminating null byte sizeof(resolv_hostname) - strlen(resolv_hostname)); ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ sizeof(resolv_hostname) - strlen(resolv_hostname) - 1 Signed-off-by: Joakim Gebart <joakim.gebart@eistec.se>		2014-10-02 12:52:39 +02:00
