Hi all,
Today's linux-next merge of the net-next tree got a conflict in
net/batman-adv/bat_iv_ogm.c between commit 7c24bbbeab41 ("batman-adv:
forward late OGMs from best next hop") from Linus' tree and commit
24a5deeb8a19 ("batman-adv: move ring_buffer helper functions in
bat_iv_ogm") from the net-next tree.I fixed it up (as specified in your email (thanks) - see below) and can carry the fix as necessary (no action is required). -- Cheers, Stephen Rothwell [email protected] diff --cc net/batman-adv/bat_iv_ogm.c index f680ee1,d07323b..0000000 --- a/net/batman-adv/bat_iv_ogm.c +++ b/net/batman-adv/bat_iv_ogm.c @@@ -30,20 -29,47 +29,63 @@@ #include "network-coding.h" /** + * batadv_dup_status - duplicate status + * @BATADV_NO_DUP: the packet is a duplicate + * @BATADV_ORIG_DUP: OGM is a duplicate in the originator (but not for the + * neighbor) + * @BATADV_NEIGH_DUP: OGM is a duplicate for the neighbor + * @BATADV_PROTECTED: originator is currently protected (after reboot) + */ +enum batadv_dup_status { + BATADV_NO_DUP = 0, + BATADV_ORIG_DUP, + BATADV_NEIGH_DUP, + BATADV_PROTECTED, +}; + ++/** + * batadv_ring_buffer_set - update the ring buffer with the given value + * @lq_recv: pointer to the ring buffer + * @lq_index: index to store the value at + * @value: value to store in the ring buffer + */ + static void batadv_ring_buffer_set(uint8_t lq_recv[], uint8_t *lq_index, + uint8_t value) + { + lq_recv[*lq_index] = value; + *lq_index = (*lq_index + 1) % BATADV_TQ_GLOBAL_WINDOW_SIZE; + } + + /** + * batadv_ring_buffer_set - compute the average of all non-zero values stored + * in the given ring buffer + * @lq_recv: pointer to the ring buffer + * + * Returns computed average value. + */ + static uint8_t batadv_ring_buffer_avg(const uint8_t lq_recv[]) + { + const uint8_t *ptr; + uint16_t count = 0, i = 0, sum = 0; + + ptr = lq_recv; + + while (i < BATADV_TQ_GLOBAL_WINDOW_SIZE) { + if (*ptr != 0) { + count++; + sum += *ptr; + } + + i++; + ptr++; + } + + if (count == 0) + return 0; + + return (uint8_t)(sum / count); + } ++ static struct batadv_neigh_node * batadv_iv_ogm_neigh_new(struct batadv_hard_iface *hard_iface, const uint8_t *neigh_addr, @@@ -1013,11 -1062,10 +1085,11 @@@ static void batadv_iv_ogm_process(cons struct batadv_neigh_node *orig_neigh_router = NULL; int has_directlink_flag; int is_my_addr = 0, is_my_orig = 0, is_my_oldorig = 0; - int is_broadcast = 0, is_bidirect; + int is_bidirect; bool is_single_hop_neigh = false; bool is_from_best_next_hop = false; - int is_duplicate, sameseq, simlar_ttl; + int sameseq, similar_ttl; + enum batadv_dup_status dup_status; uint32_t if_incoming_seqno; uint8_t *prev_sender;
