Extend union nf_inet_addr with struct in_addr and in6_addr. Useful because a lot of in-kernel IPv4 and IPv6 functions use in_addr/in6_addr. Signed-off-by:

Introduces the xt_connmark match revision 1. It uses fixed types, eventually obsoleting revision 0 some day (uses nonfixed types). (Unfixed types like "unsigned long" do not play well with mixed user-/kernelspace "bitness", e.g. 32/64, as is common on SPARC64, and need extra compat code.) Signed-off-by:

Introduces the xt_MARK target revision 2. It uses fixed types, and also uses the more expressive XOR logic. Signed-off-by:

Introduces the xt_CONNMARK target revision 1. It uses fixed types, and also uses the more expressive XOR logic. Futhermore, it allows to selectively pick bits from both the ctmark and the nfmark in the SAVE and RESTORE operations. Signed-off-by:

Fix incorrect mask value passed to ipv4_change_dsfield/ipv6_change_dsfield. Signed-off-by:
-
Jan Engelhardt authored
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.) Signed-off-by: -

Commit 88c85d81f74f92371745158aebc5cbf490412002 forgot to remove the old ipt_TOS file (whose code has been merged into xt_DSCP). Remove it now. Signed-off-by:

Most of the netfilter modules are not considered experimental anymore, the only ones I want to keep marked as EXPERIMENTAL are: - TCPOPTSTRIP target, which is brand new. - SANE helper, which is quite new. - CLUSTERIP target, which I believe hasn't had much testing despite being in the kernel for quite a long time. - SCTP match and conntrack protocol, which are a mess and need to be reviewed and cleaned up before I would trust them.

Show number of entries in trie, the size field was being set but never used, but it only counted leaves, not all entries. Refactor the two cases in fib_triestat_seq_show into a single routine. Note: the stat structure was being malloc'd but the stack usage isn't so high (288 bytes) that it is worth the additional complexity. Signed-off-by:

fib_trie_seq_show() uses two helper functions, rtn_scope() and rtn_type() that can write to static storage without locking. Just pass to them a temporary buffer to avoid potential corruption (probably not triggerable but still...) Signed-off-by:

inet_confirm_addr can be called with NULL in_dev from arp_ignore iff scope is RT_SCOPE_LINK. Lets always pass the device and check for RT_SCOPE_LINK scope inside inet_confirm_addr. This let us take network namespace from in_device a need for an additional argument. Signed-off-by:

arp_ignore has two arguments: dev & in_dev. dev is used for inet_confirm_addr calling only. inet_confirm_addr, in turn, either gets in_dev from the device passed or iterates over all network devices if the device passed is NULL. It seems logical to directly pass in_dev into inet_confirm_addr. Signed-off-by:

Some calls in the arp.c have network namespace as an argument. Getting init_net inside these functions is simply inconsistent. Fix this. Signed-off-by:

The neighbour entry will be destroyed in the case of error, so it is pointless to perform constly routing table lookup in this case. Signed-off-by:

To do so, just register the proper subsystem and create files in ->init callbacks. No other special per-namespace handling for raw sockets is required. Signed-off-by:
-
Pavel Emelyanov authored
Happily, in all the rest places (->bind callbacks only), that require the struct net, we have a socket, so get the net from it. Signed-off-by:

Pull the struct net pointer up to the showing functions to filter the sockets depending on their namespaces. Signed-off-by:
-
Pavel Emelyanov authored
This requires just to pass the appropriate struct net pointer into __raw_v[46]_lookup and skip sockets that do not belong to a needed namespace. The proper net is get from skb->dev in all the cases. Signed-off-by:

If declared as unsigned short, these fields can overflow, and whole trie logic is broken. I could not make the machine crash, but some tnode can never be freed. Note for 64 bit arches : By reordering t_key and parent in [node, leaf, tnode] structures, we can use 32 bits hole after t_key so that sizeof(struct tnode) doesnt change after this patch.

In struct tnode, we use two fields of 5 bits for 'pos' and 'bits'. Switching to plain 'unsigned char' (8 bits) take the same space because of compiler alignments, and reduce text size by 435 bytes on i386.
