From 42cb0bef0176572e2e826b49d697c653eedd7fce Mon Sep 17 00:00:00 2001 From: Antonio Quartulli Date: Sat, 16 Nov 2013 12:03:52 +0100 Subject: batman-adv: set the isolation mark in the skb if needed If a broadcast packet is coming from a client marked as isolated, then mark the skb using the isolation mark so that netfilter (or any other application) can recognise them. The mark is written in the skb based on the mask value: only bits set in the mask are substitued by those in the mark value Signed-off-by: Antonio Quartulli Signed-off-by: Marek Lindner --- net/batman-adv/translation-table.c | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) (limited to 'net/batman-adv/translation-table.c') diff --git a/net/batman-adv/translation-table.c b/net/batman-adv/translation-table.c index 1337b6925f52..63d25705cec6 100644 --- a/net/batman-adv/translation-table.c +++ b/net/batman-adv/translation-table.c @@ -3577,3 +3577,29 @@ int batadv_tt_init(struct batadv_priv *bat_priv) return 1; } + +/** + * batadv_tt_global_is_isolated - check if a client is marked as isolated + * @bat_priv: the bat priv with all the soft interface information + * @addr: the mac address of the client + * @vid: the identifier of the VLAN where this client is connected + * + * Returns true if the client is marked with the TT_CLIENT_ISOLA flag, false + * otherwise + */ +bool batadv_tt_global_is_isolated(struct batadv_priv *bat_priv, + const uint8_t *addr, unsigned short vid) +{ + struct batadv_tt_global_entry *tt; + bool ret; + + tt = batadv_tt_global_hash_find(bat_priv, addr, vid); + if (!tt) + return false; + + ret = tt->common.flags & BATADV_TT_CLIENT_ISOLA; + + batadv_tt_global_entry_free_ref(tt); + + return ret; +} -- cgit v1.2.3
