2015-03-04fib_trie: Prevent allocating tnode if bits is too big for size_tAlexander Duyck
This patch adds code to prevent us from attempting to allocate a tnode with a size larger than what can be represented by size_t. Signed-off-by: Alexander Duyck <alexander.h.duyck@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-03-04fib_trie: Update last spot w/ idx >> n->bits code and explanationAlexander Duyck
This change updates the fib_table_lookup function so that it is in sync with the fib_find_node function in terms of the explanation for the index check based on the bits value. I have also updated it from doing a mask to just doing a compare as I have found that seems to provide more options to the compiler as I have seen it turn this into a shift of the value and test under some circumstances. In addition I addressed one minor issue in which we kept computing the key ^ n->key when checking the fib aliases. I pulled the xor out of the loop in order to reduce the number of memory reads in the lookup. As a result we should save a couple cycles since the xor is only done once much earlier in the lookup.

2015-03-04fib_trie: Make fib_table rcu safeAlexander Duyck
The fib_table was wrapped in several places with an rcu_read_lock/rcu_read_unlock however after looking over the code I found several spots where the tables were being accessed as just standard pointers without any protections. This change fixes that so that all of the proper protections are in place when accessing the table to take RCU replacement or removal of the table into account.

2015-03-04fib_trie: move leaf and tnode to occupy the same spot in the key vectorAlexander Duyck
If we are going to compact the leaf and tnode we first need to make sure the fields are all in the same place. In that regard I am moving the leaf pointer which represents the fib_alias hash list to occupy what is currently the first key_vector pointer.

2015-03-04fib_trie: Fib find node should return parentAlexander Duyck
This change makes it so that the parent pointer is returned by reference in fib_find_node.

2015-03-04fib_trie: Fib walk rcu should take a tnode and key instead of a trie and a leafAlexander Duyck
This change makes it so that leaf_walk_rcu takes a tnode and a key instead of the trie and a leaf. The main idea behind this is to avoid using the leaf parent pointer as that can have additional overhead in the future as I am trying to reduce the size of a leaf down to 16 bytes on 64b systems and 12b on 32b systems.

2015-03-04fib_trie: Only resize tnodes once instead of on each leaf removal in ↵Alexander Duyck
fib_table_flush This change makes it so that we only call resize on the tnodes, instead of from each of the leaves. By doing this we can significantly reduce the amount of time spent resizing as we can update all of the leaves in the tnode first before we make any determinations about resizing. As a result we can simply free the tnode in the case that all of the leaves from a given tnode are flushed instead of resizing with each leaf removed.

Eric W. Biederman says: ==================== Basic MPLS support take 2 On top of my two pending neighbour table prep patches here is the mpls support refactored to use them, and edited to not drop routes when an interface goes down. Additionally the addition of RTA_LLGATEWAY has been replaced with the addtion of RTA_VIA. RTA_VIA being an attribute that includes the address family as well as the address of the next hop. MPLS is at it's heart simple and I have endeavoured to maintain that simplicity in my implemenation. This is an implementation of a RFC3032 forwarding engine, and basic MPLS egress logic. Which should make linux sufficient to be a mpls forwarding node or to be a LSA (Label Switched Router) as it says in all of the MPLS documents. The ingress support will follow but it deserves it's own discussion so I am pushing it separately. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2015-03-04mpls: Multicast route table change notificationsEric W. Biederman
Unlike IPv4 this code notifies on all cases where mpls routes are added or removed and it never automatically removes routes. Avoiding both the userspace confusion that is caused by omitting route updates and the possibility of a flood of netlink traffic when an interface goes doew. For now reserved labels are handled automatically and userspace is not notified. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-03-04mpls: Netlink commands to add, remove, and dump routesEric W. Biederman
This change adds two new netlink routing attributes: RTA_VIA and RTA_NEWDST. RTA_VIA specifies the specifies the next machine to send a packet to like RTA_GATEWAY. RTA_VIA differs from RTA_GATEWAY in that it includes the address family of the address of the next machine to send a packet to. Currently the MPLS code supports addresses in AF_INET, AF_INET6 and AF_PACKET. For AF_INET and AF_INET6 the destination mac address is acquired from the neighbour table. For AF_PACKET the destination mac_address is specified in the netlink configuration. I think raw destination mac address support with the family AF_PACKET will prove useful. There is MPLS-TP which is defined to operate on machines that do not support internet packets of any flavor. Further seem to be corner cases where it can be useful. At this point I don't care much either way. RTA_NEWDST specifies the destination address to forward the packet with. MPLS typically changes it's destination address at every hop. For a swap operation RTA_NEWDST is specified with a length of one label. For a push operation RTA_NEWDST is specified with two or more labels. For a pop operation RTA_NEWDST is not specified or equivalently an emtpy RTAN_NEWDST is specified. Those new netlink attributes are used to implement handling of rt-netlink RTM_NEWROUTE, RTM_DELROUTE, and RTM_GETROUTE messages, to maintain the MPLS label table. rtm_to_route_config parses a netlink RTM_NEWROUTE or RTM_DELROUTE message, verify no unhandled attributes or unhandled values are present and sets up the data structures for mpls_route_add and mpls_route_del. I did my best to match up with the existing conventions with the caveats that MPLS addresses are all destination-specific-addresses, and so don't properly have a scope. Signed-off-by: "Eric W.

2015-03-04mpls: Functions for reading and wrinting mpls labels over netlinkEric W. Biederman
Reading and writing addresses in network byte order in netlink is traditional and I see no reason to change that. MPLS is interesting as effectively it has variabely length addresses (the MPLS label stack). To represent these variable length addresses in netlink I use a valid MPLS label stack (complete with stop bit). This achieves two things: a well defined existing format is used, and the data can be interpreted without looking at it's length. Not needed to look at the length to decode the variable length network representation allows existing userspace functions such as inet_ntop to be used without needed to change their prototype.

2015-03-04mpls: Basic support for adding and removing routesEric W. Biederman
mpls_route_add and mpls_route_del implement the basic logic for adding and removing Next Hop Label Forwarding Entries from the MPLS input label map. The addition and subtraction is done in a way that is consistent with how the existing routing table in Linux are maintained. Thus all of the work to deal with NLM_F_APPEND, NLM_F_EXCL, NLM_F_REPLACE, and NLM_F_CREATE. Cases that are not clearly defined such as changing the interpretation of the mpls reserved labels is not allowed. Because it seems like the right thing to do adding an MPLS route without specifying an input label and allowing the kernel to pick a free label table entry is supported. The implementation is currently less than optimal but that can be changed. As I don't have anything else to test with only ethernet and the loopback device are the only two device types currently supported for forwarding MPLS over. Signed-off-by: "Eric W.

2015-03-04mpls: Add a sysctl to control the size of the mpls label tableEric W. Biederman
This sysctl gives two benefits. By defaulting the table size to 0 mpls even when compiled in and enabled defaults to not forwarding any packets. This prevents unpleasant surprises for users. The other benefit is that as mpls labels are allocated locally a dense table a small dense label table may be used which saves memory and is extremely simple and efficient to implement. This sysctl allows userspace to choose the restrictions on the label table size userspace applications need to cope with. Signed-off-by: "Eric W.

2015-03-04mpls: Basic routing supportEric W. Biederman
This change adds a new Kconfig option MPLS_ROUTING. The core of this change is the code to look at an mpls packet received from another machine. Look that packet up in a routing table and forward the packet on. Support of MPLS over ATM is not considered or attempted here. This implemntation follows RFC3032 and implements the MPLS shim header that can pass over essentially any network. What RFC3021 refers to as the as the Incoming Label Map (ILM) I call net->mpls.platform_label[]. What RFC3031 refers to as the Next Label Hop Forwarding Entry (NHLFE) I call mpls_route. Though calling it the label fordwarding information base (lfib) might also be valid. Further the implemntation forwards packets as described in RFC3032. There is no need and given the original motivation for MPLS a strong discincentive to have a flexible label forwarding path. In essence the logic is the topmost label is read, looked up, removed, and replaced by 0 or more new lables and the sent out the specified interface to it's next hop. Quite a few optional features are not implemented here. Among them are generation of ICMP errors when the TTL is exceeded or the packet is larger than the next hop MTU (those conditions are detected and the packets are dropped instead of generating an icmp error). The traffic class field is always set to 0. The implementation focuses on IP over MPLS and does not handle egress of other kinds of protocols. Instead of implementing coordination with the neighbour table and sorting out how to input next hops in a different address family (for which there is value). I was lazy and implemented a next hop mac address instead. The code is simpler and there are flavor of MPLS such as MPLS-TP where neither an IPv4 nor an IPv6 next hop is appropriate so a next hop by mac address would need to be implemented at some point. Two new definitions AF_MPLS and PF_MPLS are exposed to userspace. Decoding the mpls header must be done by first byeswapping a 32bit bit endian word into the local cpu endian and then bit shifting to extract the pieces. There is no C bit-field that can represent a wire format mpls header on a little endian machine as the low bits of the 20bit label wind up in the wrong half of third byte. Therefore internally everything is deal with in cpu native byte order except when writing to and reading from a packet. For management simplicity if a label is configured to forward out an interface that is down the packet is dropped early. Similarly if an network interface is removed rt_dev is updated to NULL (so no reference is preserved) and any packets for that label are dropped. Keeping the label entries in the kernel allows the kernel label table to function as the definitive source of which labels are allocated and which are not. Signed-off-by: "Eric W.

Allowing the lookup logic to be shared between the different implementations. At what appears to be no cost. (Aka the same assembly is generated for ip6_finish_output2 and ip_finish_output2). After that I add a simple function that takes an address family and an address consults the neighbour table and sends the packet to the appropriate location. The address family argument decoupls callers of neigh_xmit from the addresses families the packets are sent over. (Aka The ipv6 module can be loaded after mpls and a previously configured ipv6 next hop will start working).

For MPLS I am building the code so that either the neighbour mac address can be specified or we can have a next hop in ipv4 or ipv6. The kind of next hop we have is indicated by the neighbour table pointer. A neighbour table pointer of NULL is a link layer address. A non-NULL neighbour table pointer indicates which neighbour table and thus which address family the next hop address is in that we need to look up.

While looking at the mpls code I found myself writing yet another version of neigh_lookup_noref. We currently have __ipv4_lookup_noref and __ipv6_lookup_noref. So to make my work a little easier and to make it a smidge easier to verify/maintain the mpls code in the future I stopped and wrote ___neigh_lookup_noref. Then I rewote __ipv4_lookup_noref and __ipv6_lookup_noref in terms of this new function. I tested my new version by verifying that the same code is generated in ip_finish_output2 and ip6_finish_output2 where these functions are inlined. To get to ___neigh_lookup_noref I added a new neighbour cache table function key_eq. So that the static size of the key would be available. I also added __neigh_lookup_noref for people who want to to lookup a neighbour table entry quickly but don't know which neibhgour table they are going to look up. Signed-off-by: "Eric W.

Matthew updates the fm10k driver by cleaning up code comments and whitespace issues. Also modifies the tunnel length header check, to make it more robust by calculating the inner L4 header length based on whether it is TCP or UDP. Implemented ndo_features_check() that allows drivers to report their offload capabilities per-skb. Neerav updates the i40e driver to skip over priority tagging if DCB is not enabled. Fixes an issue where the driver is not flushing out the DCBNL app table for applications that are not present in the local DCBX application configuration TLVs. Fixed i40e where, in the case of MFP mode, the driver was returning the incorrect number of traffic classes for partitions that are not enabled for iSCSI. Even though the driver was not configuring these traffic classes in the transmit scheduler for the NIC partitions, it does use this map to setup the queue mappings. Shannon updates i40e/i40evf to include the firmware build number in the formatted firmware version string. Akeem adds a safety net (by adding a 'default' case) for the possible unmatched switch calls. Mitch updates i40e to not automatically disable PF loopback at runtime, now that we have the functionality to enable and disable PF loopback. This fix cleans up a bogus error message when removing the PF module with VFs enabled. Adds a extra check to make sure that the indirection table pointer is valid before dereferencing it. Anjali enables i40e to enable more than the max RSS qps when running in a single TC mode for the main VSI. It is possible to enable as many as num_online_cpus().

From Matthew Thode. 9) Use {,__}set_current_state() where appropriate, from Fabian Frederick. 10) Revert byte queue limits support in r8169 driver, it's causing regressions we can't figure out. 11) tcp_should_expand_sndbuf() erroneously uses tp->packets_out to measure packets in flight, properly use tcp_packets_in_flight() instead. From Neal Cardwell. 12) Fix accidental removal of support for bluetooth in CSR based Intel wireless cards. From Marcel Holtmann. 13) We accidently added a behavioral change between native and compat tasks, wrt testing the MSG_CMSG_COMPAT bit. Just ignore it if the user happened to set it in a native binary as that was always the behavior we had. From Catalin Marinas. 14) Check genlmsg_unicast() return valud in hwsim netlink tx frame handling, from Bob Copeland. 15) Fix stale ->radar_required setting in mac80211 that can prevent starting new scans, from Eliad Peller. 16) Fix memory leak in nl80211 monitor, from Johannes Berg. 17) Fix race in TX index handling in xen-netback, from David Vrabel. 18) Don't enable interrupts in amx-xgbe driver until all software et al. state is ready for the interrupt handler to run. From Thomas Lendacky. 19) Add missing netlink_ns_capable() checks to rtnl_newlink(), from Eric W Biederman. 20) The amount of header space needed in macvtap was not calculated properly, fix it otherwise we splat past the beginning of the packet. From Eric Dumazet. 21) Fix bcmgenet TCP TX perf regression, from Jaedon Shin. 22) Don't raw initialize or mod timers, use setup_timer() and mod_timer() instead. From Vaishali Thakkar. 23) Fix software maintained statistics in bcmgenet and systemport drivers, from Florian Fainelli. 24) DMA descriptor updates in sh_eth need proper memory barriers, from Ben Hutchings. 25) Don't do UDP Fragmentation Offload on RAW sockets, from Michal Kubecek. 26) Openvswitch's non-masked set actions aren't constructed properly into netlink messages, fix from Joe Stringer. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (116 commits) openvswitch: Fix serialization of non-masked set actions. gianfar: Reduce logging noise seen due to phy polling if link is down ibmveth: Add function to enable live MAC address changes net: bridge: add compile-time assert for cb struct size udp: only allow UFO for packets from SOCK_DGRAM sockets sh_eth: Really fix padding of short frames on TX Revert "sh_eth: Enable Rx descriptor word 0 shift for r8a7790" sh_eth: Fix RX recovery on R-Car in case of RX ring underrun sh_eth: Ensure proper ordering of descriptor active bit write/read net/mlx4_en: Disbale GRO for incoming loopback/selftest packets net/mlx4_core: Fix wrong mask and error flow for the update-qp command net: systemport: fix software maintained statistics net: bcmgenet: fix software maintained statistics rxrpc: don't multiply with HZ twice rxrpc: terminate retrans loop when sending of skb fails net/hsr: Fix NULL pointer dereference and refcnt bugs when deleting a HSR interface. net: pasemi: Use setup_timer and mod_timer net: stmmac: Use setup_timer and mod_timer net: 8390: axnet_cs: Use setup_timer and mod_timer net: 8390: pcnet_cs: Use setup_timer and mod_timer ...
