2013-03-19libsec: avoid undefined CXi Wang1-2/+1
gcc compiles `p + length < p' into 'length < 0' since pointer overflow is undefined behavior in C. This breaks the check against a large `length'. Use `length > pend - p' instead. There's no need to check `length < 0' since `length' is from length_decode() and should be non-negative. === Try the simplified code. void bar(void); void foo(unsigned char *p, int length) { if (p + length < p) bar(); } $ gcc -S -o - t.c -O2 ... foo: .LFB0: .cfi_startproc testl %esi, %esi js .L4 rep ret .L4: jmp bar .cfi_endproc Clearly `p' is not used at all.
