[lwip-devel] [patch #8683] Addresses configured with router advertisment are never forgot

[Stian Sebastian Skjelstad]

Follow-up Comment #5, patch #8683 (project lwip):

Patch 4:

Looking at the current value of the defines:

#define IP6_ADDR_INVALID      0x00
#define IP6_ADDR_TENTATIVE    0x08
#define IP6_ADDR_TENTATIVE_1  0x09 /* 1 probe sent */
#define IP6_ADDR_TENTATIVE_2  0x0a /* 2 probes sent */
#define IP6_ADDR_TENTATIVE_3  0x0b /* 3 probes sent */
#define IP6_ADDR_TENTATIVE_4  0x0c /* 4 probes sent */
#define IP6_ADDR_TENTATIVE_5  0x0d /* 5 probes sent */
#define IP6_ADDR_TENTATIVE_6  0x0e /* 6 probes sent */
#define IP6_ADDR_TENTATIVE_7  0x0f /* 7 probes sent */

I guess at some point in time, IP6_ADDR_TENTATIVE_1 was defined to 0x01, _2 to
0x02 etc.

The present code does this:
if ((netif->ip6_addr_state[i] & 0x07) >= LWIP_IPV6_DUP_DETECT_ATTEMPTS)
