From de74c16996287250f0d947663127f80c6beebd3c Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Sun, 5 Jul 2009 18:26:37 +0200 Subject: netfilter: xtables: combine struct xt_match_param and xt_target_param The structures carried - besides match/target - almost the same data. It is possible to combine them, as extensions are evaluated serially, and so, the callers end up a little smaller. text data bss filename -15318 740 104 net/ipv4/netfilter/ip_tables.o +15286 740 104 net/ipv4/netfilter/ip_tables.o -15333 540 152 net/ipv6/netfilter/ip6_tables.o +15269 540 152 net/ipv6/netfilter/ip6_tables.o Signed-off-by: Jan Engelhardt --- net/bridge/netfilter/ebtables.c | 30 +++++++++++++++--------------- 1 file changed, 15 insertions(+), 15 deletions(-) (limited to 'net/bridge') diff --git a/net/bridge/netfilter/ebtables.c b/net/bridge/netfilter/ebtables.c index 1d8c2c0a7470..290d43541d46 100644 --- a/net/bridge/netfilter/ebtables.c +++ b/net/bridge/netfilter/ebtables.c @@ -86,7 +86,7 @@ static struct xt_target ebt_standard_target = { static inline int ebt_do_watcher(const struct ebt_entry_watcher *w, struct sk_buff *skb, - struct xt_target_param *par) + struct xt_action_param *par) { par->target = w->u.watcher; par->targinfo = w->data; @@ -95,8 +95,9 @@ ebt_do_watcher(const struct ebt_entry_watcher *w, struct sk_buff *skb, return 0; } -static inline int ebt_do_match (struct ebt_entry_match *m, - const struct sk_buff *skb, struct xt_match_param *par) +static inline int +ebt_do_match(struct ebt_entry_match *m, const struct sk_buff *skb, + struct xt_action_param *par) { par->match = m->u.match; par->matchinfo = m->data; @@ -186,14 +187,13 @@ unsigned int ebt_do_table (unsigned int hook, struct sk_buff *skb, const char *base; const struct ebt_table_info *private; bool hotdrop = false; - struct xt_match_param mtpar; - struct xt_target_param tgpar; + struct xt_action_param acpar; - mtpar.family = tgpar.family = NFPROTO_BRIDGE; - mtpar.in = tgpar.in = in; - mtpar.out = tgpar.out = out; - mtpar.hotdrop = &hotdrop; - mtpar.hooknum = tgpar.hooknum = hook; + acpar.family = NFPROTO_BRIDGE; + acpar.in = in; + acpar.out = out; + acpar.hotdrop = &hotdrop; + acpar.hooknum = hook; read_lock_bh(&table->lock); private = table->private; @@ -214,7 +214,7 @@ unsigned int ebt_do_table (unsigned int hook, struct sk_buff *skb, if (ebt_basic_match(point, eth_hdr(skb), in, out)) goto letscontinue; - if (EBT_MATCH_ITERATE(point, ebt_do_match, skb, &mtpar) != 0) + if (EBT_MATCH_ITERATE(point, ebt_do_match, skb, &acpar) != 0) goto letscontinue; if (hotdrop) { read_unlock_bh(&table->lock); @@ -227,7 +227,7 @@ unsigned int ebt_do_table (unsigned int hook, struct sk_buff *skb, /* these should only watch: not modify, nor tell us what to do with the packet */ - EBT_WATCHER_ITERATE(point, ebt_do_watcher, skb, &tgpar); + EBT_WATCHER_ITERATE(point, ebt_do_watcher, skb, &acpar); t = (struct ebt_entry_target *) (((char *)point) + point->target_offset); @@ -235,9 +235,9 @@ unsigned int ebt_do_table (unsigned int hook, struct sk_buff *skb, if (!t->u.target->target) verdict = ((struct ebt_standard_target *)t)->verdict; else { - tgpar.target = t->u.target; - tgpar.targinfo = t->data; - verdict = t->u.target->target(skb, &tgpar); + acpar.target = t->u.target; + acpar.targinfo = t->data; + verdict = t->u.target->target(skb, &acpar); } if (verdict == EBT_ACCEPT) { read_unlock_bh(&table->lock); -- cgit v1.2.3
