* neigh: optimize neigh_parms_release()Nicolas Dichtel2014-10-291-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | In neigh_parms_release() we loop over all entries to find the entry given in argument and being able to remove it from the list. By using a double linked list, we can avoid this loop. Here are some numbers with 30 000 dummy interfaces configured: Before the patch: $ time rmmod dummy real 2m0.118s user 0m0.000s sys 1m50.048s After the patch: $ time rmmod dummy real 1m9.970s user 0m0.000s sys 0m47.976s Suggested-by: Thierry Herbelot <thierry.herbelot@6wind.com> Signed-off-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Acked-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.

* net: introduce napi_schedule_irqoff()Eric Dumazet2014-10-291-0/+13
| | | | | | | | | | | | | | napi_schedule() can be called from any context and has to mask hard irqs. Add a variant that can only be called from hard interrupts handlers or when irqs are already masked. Many NIC drivers can use it from their hard IRQ handler instead of generic variant.

* net: ipv6: Add a sysctl to make optimistic addresses useful candidatesErik Kline2014-10-292-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a sysctl that causes an interface's optimistic addresses to be considered equivalent to other non-deprecated addresses for source address selection purposes. Preferred addresses will still take precedence over optimistic addresses, subject to other ranking in the source address selection algorithm. This is useful where different interfaces are connected to different networks from different ISPs (e.g., a cell network and a home wifi network). The current behaviour complies with RFC 3484/6724, and it makes sense if the host has only one interface, or has multiple interfaces on the same network (same or cooperating administrative domain(s), but not in the multiple distinct networks case. For example, if a mobile device has an IPv6 address on an LTE network and then connects to IPv6-enabled wifi, while the wifi IPv6 address is undergoing DAD, IPv6 connections will try use the wifi default route with the LTE IPv6 address, and will get stuck until they time out. Also, because optimistic nodes can receive frames, issue an RTM_NEWADDR as soon as DAD starts (with the IFA_F_OPTIMSTIC flag appropriately set). A second RTM_NEWADDR is sent if DAD completes (the address flags have changed), otherwise an RTM_DELADDR is sent. Also: add an entry in ip-sysctl.txt for optimistic_dad.

* tcp: allow for bigger reordering levelEric Dumazet2014-10-292-5/+3
| | | | | | | | | | | | | | | | | | | While testing upcoming Yaogong patch (converting out of order queue into an RB tree), I hit the max reordering level of linux TCP stack. Reordering level was limited to 127 for no good reason, and some network setups [1] can easily reach this limit and get limited throughput. Allow a new max limit of 300, and add a sysctl to allow admins to even allow bigger (or lower) values if needed.

* datapath: Rename last_action() as nla_is_last() and move to netlink.hSimon Horman2014-10-281-0/+10
| | | | | | | | | | | | | | | | | | | The original motivation for this change was to allow the helper to be used in files other than actions.c as part of work on an odp select group action. It was as pointed out by Thomas Graf that this helper would be best off living in netlink.h. Furthermore, I think that the generic nature of this helper means it is best off in netlink.h regardless of if it is used more than one .c file or not. Thus, I would like it considered independent of the work on an odp select group action.

* bridge: Add support for IEEE 802.11 Proxy ARPKyeyoon Park2014-10-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | This feature is defined in IEEE Std 802.11-2012, 10.23.13. It allows the AP devices to keep track of the hardware-address-to-IP-address mapping of the mobile devices within the WLAN network. The AP will learn this mapping via observing DHCP, ARP, and NS/NA frames. When a request for such information is made (i.e. ARP request, Neighbor Solicitation), the AP will respond on behalf of the associated mobile device. In the process of doing so, the AP will drop the multicast request frame that was intended to go out to the wireless medium. It was recommended at the LKS workshop to do this implementation in the bridge layer. vxlan.c is already doing something very similar. The DHCP snooping code will be added to the userspace application (hostapd) per the recommendation. This RFC commit is only for IPv4. A similar approach in the bridge layer will be taken for IPv6 as well. Signed-off-by: Kyeyoon Park <kyeyoonp@codeaurora.org> Signed-off-by: David S. Miller <davem@davemloft.net>

Otherwise, users may crash their kernel if they attach a nat/masq rule to a non nat chain. 3) Fix hook validation in nft_compat when non-base chains are used. Basically, initialize hook_mask to zero. 4) Make sure you use match/targets in nft_compat from the right chain type. The existing validation relies on the table name which can be avoided by 5) Better netlink attribute validation in nft_nat. This expression has to reject the configuration when no address and proto configurations are specified. 6) Interpret NFTA_NAT_REG_*_MAX if only if NFTA_NAT_REG_*_MIN is set. Yet another sanity check to reject incorrect configurations from userspace. 7) Conditional NAT attribute dumping depending on the existing configuration. ==================== Signed-off-by: David S.

| * netfilter: nf_tables: restrict nat/masq expressions to nat chain typePablo Neira Ayuso2014-10-132-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the missing validation code to avoid the use of nat/masq from non-nat chains. The validation assumes two possible configuration scenarios: 1) Use of nat from base chain that is not of nat type. Reject this configuration from the nft_*_init() path of the expression. 2) Use of nat from non-base chain. In this case, we have to wait until the non-base chain is referenced by at least one base chain via jump/goto. This is resolved from the nft_*_validate() path which is called from nf_tables_check_loops(). The user gets an -EOPNOTSUPP in both cases. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

It went into a 16-bit flags field but was defined at (1 << 16). Since we have no 10-bit i2c devices on the other side of the tunnel on any known devices this was never a problem. Until we do it makes sense to remove this code. On the EC side the code to handle this flag was removed in <https://chromium-review.googlesource.com/204162>.

However, we still need to deal systems that are PCI only (no ACPI to back up). In order to support such systems, we allow the DMA filter function and its corresponding parameter via pxa2xx_spi_master platform data. Then when the pxa2xx_spi_dma_setup() doesn't find the channel via ACPI, it falls back to use the given filter function.

However, we access them as a single 64-bit value or as a bitmap pointer in the generic vgic code, which breaks BE support. Instead, store them as u64 values on the vgic structure and do the word-swapping in the assembly code, which already handles the byte order for BE systems.
