2008-01-28[NETFILTER]: Update modules' descriptionsJan Engelhardt1-1/+1
Updates the MODULE_DESCRIPTION() tags for all Netfilter modules, actually describing what the module does and not just "netfilter XYZ target".

2008-01-28[NETFILTER]: xt_TOS: Properly set the TOS fieldJan Engelhardt1-2/+2
Fix incorrect mask value passed to ipv4_change_dsfield/ipv6_change_dsfield. Signed-off-by: Jan Engelhardt <jengelh@computergmbh.de> Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-28[NETFILTER]: xt_TOS: Change semantic of mask valueJan Engelhardt1-1/+1
This patch changes the behavior of xt_TOS v1 so that the mask value the user supplies means "zero out these bits" rather than "keep these bits". This is more easy on the user, as (I would assume) people keep more bits than zeroing, so, an example: Action: Set bit 0x01. before (&): iptables -j TOS --set-tos 0x01/0xFE after (&~): iptables -j TOS --set-tos 0x01/0x01 This is not too "tragic" with xt_TOS, but where larger fields are used (e.g. proposed xt_MARK v2), `--set-xmar 0x01/0x01` vs. `--set-xmark 0x01/0xFFFFFFFE` really makes a difference. Other target(!) modules, such as xt_TPROXY also use &~ rather than &, so let's get to a common ground. (Since xt_TOS has not yet left the development tree en direction to mainline, the semantic can be changed as proposed without breaking iptables.)

2008-01-28[NETFILTER]: IPv6 capable xt_TOS v1 targetJan Engelhardt1-0/+63
Extends the xt_DSCP target by xt_TOS v1 to add support for selectively setting and flipping any bit in the IPv4 TOS and IPv6 Priority fields. (ipt_TOS and xt_DSCP only accepted a limited range of possible values.)

2008-01-28[NETFILTER]: Merge ipt_TOS into xt_DSCPJan Engelhardt1-0/+51
Merge ipt_TOS into xt_DSCP. Merge ipt_TOS (tos v0 target) into xt_DSCP. They both modify the same field in the IPv4 header, so it seems reasonable to keep them in one piece. This is part two of the implicit 4-patch series to move tos to xtables and extend it by IPv6.

2007-10-15[NETFILTER]: Replace sk_buff ** with sk_buff *Herbert Xu1-8/+8
With all the users of the double pointers removed, this patch mops up by finally replacing all occurances of sk_buff ** in the netfilter API by sk_buff *. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2007-10-15[NETFILTER]: Do not copy skb in skb_make_writableHerbert Xu1-2/+2
Now that all callers of netfilter can guarantee that the skb is not shared, we no longer have to copy the skb in skb_make_writable. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>

2007-04-25[SK_BUFF]: Introduce ipv6_hdr(), remove skb->nh.ipv6hArnaldo Carvalho de Melo1-2/+2
Now the skb->nh union has just one member, .raw, i.e. it is just like the skb->mac union, strange, no? I'm just leaving it like that till the transport layer is done with, when we'll rename skb->mac.raw to skb->mac_header (or ->mac_header_offset?), ditto for ->{h,nh}.
