Subject: [zebra 18573] PATCH ospfd: byte order error in assert statement
I found a bug in the ospfd code tickled this morning by a Type 1
LSA with exactly 62 entries (LSA length of 768, or 0x0300).
A missing ntohs in ospf_lsa.c:ospf_lsa_different() causes an assert
statement to fail, stopping ospfd.
> assert (l1->data->length > OSPF_LSA_HEADER_SIZE);
So, a length of type 768 turns into a length of 3 which is
obviously less than 20.
