+Subject: [PATCH] bonding: fix ns validation on backup slaves
+References: bsc#1012628
+Patch-mainline: 6.2.12
+Git-commit: 4598380f9c548aa161eb4e990a1583f0a7d1e0d7
+
+[ Upstream commit 4598380f9c548aa161eb4e990a1583f0a7d1e0d7 ]
+
+When arp_validate is set to 2, 3, or 6, validation is performed for
+backup slaves as well. As stated in the bond documentation, validation
+involves checking the broadcast ARP request sent out via the active
+slave. This helps determine which slaves are more likely to function in
+the event of an active slave failure.
+
+However, when the target is an IPv6 address, the NS message sent from
+the active interface is not checked on backup slaves. Additionally,
+based on the bond_arp_rcv() rule b, we must reverse the saddr and daddr
+when checking the NS message.
+
+Note that when checking the NS message, the destination address is a
+multicast address. Therefore, we must convert the target address to
+solicited multicast in the bond_get_targets_ip6() function.
+
+Prior to the fix, the backup slaves had a mii status of "down", but
+after the fix, all of the slaves' mii status was updated to "UP".
+
+Fixes: 4e24be018eb9 ("bonding: add new parameter ns_targets")
