Brooks Davis ccbbd187b1 Fix a stack overflow in mount_smbfs when hostname is too long. The local hostname was blindly copied into the to the nn_name array. When the hostname exceeded 16 bytes, it would overflow. Truncate the hostname to 15 bytes plus a 0 terminator which is the "workstation name" suffix. Use defensive strlcpy() when filling nn_name in all cases.
