* netfilter: nf_tables: add generic macros to check for generation maskPablo Neira Ayuso2016-06-242-38/+32Star
| | | | | | | | Thus, we can reuse these to check the genmask of any object type, not only rules. This is required now that tables, chain and sets will get a generation mask field too in follow up patches. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* netfilter: xt_NFLOG: nflog-range does not truncate packetsVishwanath Pai2016-06-244-4/+21
| | | | | | | | | | | | | | | | | | | li->u.ulog.copy_len is currently ignored by the kernel, we should truncate the packet to either li->u.ulog.copy_len (if set) or copy_range before sending it to userspace. 0 is a valid input for copy_len, so add a new flag to indicate whether this was option was specified by the user or not. Add two flags to indicate whether nflog-size/copy_len was set or not. XT_NFLOG_F_COPY_LEN is for XT_NFLOG and NFLOG_F_COPY_LEN for nfnetlink_log On the userspace side, this was initially represented by the option nflog-range, this will be replaced by --nflog-size now. --nflog-range would still exist but does not do anything.

* netfilter: nf_reject_ipv4: don't send tcp RST if the packet is non-TCPLiping Zhang2016-06-241-0/+3
| | | | | | | | | | | | | | | | In iptables, if the user add a rule to send tcp RST and specify the non-TCP protocol, such as UDP, kernel will reject this request. But in nftables, this validity check only occurs in nft tool, i.e. only in userspace. This means that user can add such a rule like follows via nfnetlink: "nft add rule filter forward ip protocol udp reject with tcp reset" This will generate some confusing tcp RST packets. So we should send tcp RST only when it is TCP packet. Signed-off-by: Liping Zhang <liping.zhang@spreadtrum.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* netfilter: Allow xt_owner in any user namespaceEric W. Biederman2016-06-231-6/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Making this work is a little tricky as it really isn't kosher to change the xt_owner_match_info in a check function. Without changing xt_owner_match_info we need to know the user namespace the uids and gids are specified in. In the common case net->user_ns == current_user_ns(). Verify net->user_ns == current_user_ns() in owner_check so we can later assume it in owner_mt. In owner_check also verify that all of the uids and gids specified are in net->user_ns and that the expected min/max relationship exists between the uids and gids in xt_owner_match_info. In owner_mt get the network namespace from the outgoing socket, as this must be the same network namespace as the netfilter rules, and use that network namespace to find the user namespace the uids and gids in xt_match_owner_info are encoded in. Then convert from their encoded from into the kernel internal format for uids and gids and perform the owner match. Similar to ping_group_range, this code does not try to detect noncontiguous UID/GID ranges. Signed-off-by: "Eric W.

* netfilter: move zone info into struct nf_connFlorian Westphal2016-06-234-57/+16Star
| | | | | | | | | | | | | | | Curently we store zone information as a conntrack extension. This has one drawback: for every lookup we need to fetch the zone data from the extension area. This change place the zone data directly into the main conntrack object structure and then removes the zone conntrack extension. The zone data is just 4 bytes, it fits into a padding hole before the tuplehash info, so we do not even increase the nf_conn structure size.

* netfilter: x_tables: fix possible ZERO_SIZE_PTR pointer dereferencing error.Xiubo Li2016-06-231-0/+3
| | | | | | | | | | | | | | | | | | | Since we cannot make sure that the 'hook_mask' will always be none zero here. If it equals to zero, the num_hooks will be zero too, and then kmalloc() will return ZERO_SIZE_PTR, which is (void *)16. Then the following error check will fails: ops = kmalloc(sizeof(*ops) * num_hooks, GFP_KERNEL); if (ops == NULL) return ERR_PTR(-ENOMEM); So this patch will fix this with just doing the zero check before kmalloc() is called. Maybe the case above will never happen here, but in theory. Signed-off-by: Xiubo Li <lixiubo@cmss.chinamobile.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* net: disable fragment reassembly if high_thresh is zeroMichal Kubeček2016-06-061-1/+1
| | | | | | | | | | | | | | | | | | | | Before commit 6d7b857d541e ("net: use lib/percpu_counter API for fragmentation mem accounting"), setting the reassembly high threshold to 0 prevented fragment reassembly as first fragment would be always evicted before second could be added to the queue. While inefficient, some users apparently relied on this method. Since the commit mentioned above, a percpu counter is used for reassembly memory accounting and high batch size avoids taking slow path in most common scenarios. As a result, a whole full sized packet can be reassembled without the percpu counter's main counter changing its value so that even with high_thresh set to 0, fragmented packets can be still reassembled and processed. Add explicit check preventing reassembly if high threshold is zero. Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: David S. Miller <davem@davemloft.net>

They implement a new binding for DSA, which removes a few limitations of the current DSA binding. In particular, it allows switches to be true Linux devices. These devices can be on any type of bus, unlike the old DSA binding which assumes MDIO. See the commit log for more details. The second to last patch modifies an existing boards device tree to use the new binding, giving a good example of how switches can be true MDIO devices. The last patch documents the new binding. Thanks go to Florian and Vivien for reviewing, testing and bug fixing these patches.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing DSA binding has a number of limitations and problems. The main problem is that it cannot represent a switch as a linux device, hanging off some bus. It is limited to one CPU port. The DSA platform device is artificial, and does not really represent hardware. Implement a new binding which can be embedded into any type of node on a bus to represent one switch device, and its links to other switches.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The switch implements a generic MDIO bus, which could host more than PHYs. It is conventional to use _mdio_ or _mii_ in the function name, so rename them. Also postfix make the historically first read/write function with _direct, to help distinguish it from _indirect and _ppu. While touching these functions, remove some of the _ prefixes, which we are deprecating.
