Stefan Sperling gerrit-no-reply at lists.osmocom.orgHello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/10054 to look at the new patch set (#4). Change subject: fix unaligned access in build_ipcp_pco() ...................................................................... fix unaligned access in build_ipcp_pco() IPCP data can begin at any byte location in the pco_req->v array. Casting to a 'struct ipcp_hdr' pointer could lead to unaligned access. Parse IPCP data with u_int8_t pointers instead to avoid this problem. Add some length checks while here. pco_contains_proto() and ipcp_contains_option() now receive the minimum size of the data the caller is looking for, and only return pointers to items of sufficient size. Also fix an inifinite loop in ipcp_contains_option() by refusing IPCP options with length small than 2. Previously, a zero length option would trigger an infinite loop in the parser.
