[lwip-devel] [bug #48162] Off-link RA prefix with bit A set is ignored resulting in no address

[Izik goldraich]

Follow-up Comment #2, bug #48162 (project lwip):

please note Verison wireless send RA with A=1 , L=0.
( so a device using LWIP will not have IPv6 address, while a device using
Linux will have one)

as a workaround (till this issue resolve) should we ignore the L bit as
follows:


$ p4 diff2 src/core/ipv6/nd6.c#2 src/core/ipv6/nd6.c#1
==== src/core/ipv6/nd6.c#2 (text) - src/core/ipv6/nd6.c#1 (text) ==== content

<         /* since VZW configure A=1,L=0 . it is better to ignore the L bit
<         if (prefix_opt->flags & ND6_PREFIX_FLAG_ON_LINK) {*/
<         {
---
> 
>         if (prefix_opt->flags & ND6_PREFIX_FLAG_ON_LINK) {
