The mask indicates the bits one wants to zero out, so it needs to be

When extended status codes are available, such as ENOMEM on failed
allocations, or subsequent functions (e.g. nf_ct_get_l3proto), passing
them up to userspace seems like a good idea compared to just always
EINVAL.Signed-off-by: Jan Engelhardt

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 0x01/0x01This 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.)Signed-off-by: Jan Engelhardt

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.

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.Signed-off-by: Jan Engelhardt

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
