From 9b42078ed6edfe04e9dc9a59b946ad912aeef717 Mon Sep 17 00:00:00 2001 From: Gerrit Renker Date: Fri, 10 Nov 2006 11:22:32 -0200 Subject: [DCCP]: Combine allocating & zeroing header space on skb This is a code simplification: it combines three often recurring operations into one inline function, * allocate `len' bytes header space in skb * fill these `len' bytes with zeroes * cast the start of this header space as dccp_hdr Signed-off-by: Gerrit Renker Signed-off-by: Arnaldo Carvalho de Melo --- net/dccp/ipv6.c | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) (limited to 'net/dccp/ipv6.c') diff --git a/net/dccp/ipv6.c b/net/dccp/ipv6.c index 6f1c2ad8860..116bddb64b8 100644 --- a/net/dccp/ipv6.c +++ b/net/dccp/ipv6.c @@ -537,9 +537,7 @@ static void dccp_v6_ctl_send_reset(struct sk_buff *rxskb) skb_reserve(skb, dccp_v6_ctl_socket->sk->sk_prot->max_header); - skb->h.raw = skb_push(skb, dccp_hdr_reset_len); - dh = dccp_hdr(skb); - memset(dh, 0, dccp_hdr_reset_len); + dh = dccp_zeroed_hdr(skb, dccp_hdr_reset_len); /* Swap the send and the receive. */ dh->dccph_type = DCCP_PKT_RESET; @@ -601,9 +599,7 @@ static void dccp_v6_reqsk_send_ack(struct sk_buff *rxskb, skb_reserve(skb, dccp_v6_ctl_socket->sk->sk_prot->max_header); - skb->h.raw = skb_push(skb, dccp_hdr_ack_len); - dh = dccp_hdr(skb); - memset(dh, 0, dccp_hdr_ack_len); + dh = dccp_zeroed_hdr(skb, dccp_hdr_ack_len); /* Build DCCP header and checksum it. */ dh->dccph_type = DCCP_PKT_ACK; -- cgit v1.2.3
