Pull ACPI and power management fixes from Rafael Wysocki: "These are fixes received after my previous pull request plus one that has been in the works for quite a while, but its previous version caused problems to happen, so it's been deferred till now. Fixed are two recent regressions (MFD enumeration and cpufreq-dt), ACPI EC regression introduced in 3.17, system suspend error code path regression introduced in 3.15, an older bug related to recovery from failing resume from hibernation and a cpufreq-dt driver issue related to operation performance points. Specifics: - Fix a crash on r8a7791/koelsch during resume from system suspend caused by a recent cpufreq-dt commit (Geert Uytterhoeven). - Fix an MFD enumeration problem introduced by a recent commit adding ACPI support to the MFD subsystem that exposed a weakness in the ACPI core causing ACPI enumeration to be applied to all devices associated with one ACPI companion object, although it should be used for one of them only (Mika Westerberg). - Fix an ACPI EC regression introduced during the 3.17 cycle causing some Samsung laptops to misbehave as a result of a workaround targeted at some Acer machines. That includes a revert of a commit that went too far and a quirk for the Acer machines in question. From Lv Zheng. - Fix a regression in the system suspend error code path introduced during the 3.15 cycle that causes it to fail to take errors from asychronous execution of "late" suspend callbacks into account (Imre Deak). - Fix a long-standing bug in the hibernation resume error code path that fails to roll back everything correcty on "freeze" callback errors and leaves some devices in a "suspended" state causing more breakage to happen subsequently (Imre Deak). - Make the cpufreq-dt driver disable operation performance points that are not supported by the VR connected to the CPU voltage plane with acceptable tolerance instead of constantly failing voltage scaling later on (Lucas Stach)" * tag 'pm+acpi-3.18-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / EC: Fix regression due to conflicting firmware behavior between Samsung and Acer.

Pull PCI fixes from Bjorn Helgaas: "These changes, intended for v3.18, fix: Sysfs - Fix "enable" filename change (Greg Kroah-Hartman) An unintentional sysfs filename change in commit 5136b2da ("PCI: convert bus code to use dev_groups"), which appeared in v3.13, changed "enable" to "enabled", and this changes it back.

Rusty noticed a Really Bad Bug (tm) in my NT fix. The entry code reads out of bounds, causing the NT fix to be unreliable. But, and this is much, much worse, if your stack is somehow just below the top of the direct map (or a hole), you read out of bounds and crash. Excerpt from the crash: [ 1.129513] RSP: 0018:ffff88001da4bf88 EFLAGS: 00010296 2b:* f7 84 24 90 00 00 00 testl $0x4000,0x90(%rsp) That read is deterministically above the top of the stack. I thought I even single-stepped through this code when I wrote it to check the offset, but I clearly screwed it up.

The cpsw driver did not support the IFF_ALLMULTI flag which makes dynamic multicast routing not work. Related to this, when enabling IFF_PROMISC in switch mode, all registered multicast addresses are flushed, resulting in only broadcast and unicast traffic being received. A new cpsw_ale_set_allmulti function now scans through the ALE entry table and adds/removes the host port from the unregistered multicast port mask of each vlan entry depending on the state of IFF_ALLMULTI. In promiscious mode, cpsw_ale_set_allmulti is used to force reception of all multicast traffic in addition to the unicast and broadcast traffic. With this change dynamic multicast and promiscious mode both work in switch mode. Signed-off-by:

0d961b3b (drivers: net: cpsw: fix buggy loop condition) accidentally fixed a loop comparison in too many places while fixing a real bug. It was correct to fix the dual_emac mode section since there 'i' is used as an index into priv->slaves which is a 0 based array. However the other two changes (which are only used in switch mode) are wrong since there 'i' is actually the ALE port number, and port 0 is the host port, while port 1 and up are the slave ports. Putting the loop condition back in the switch mode section fixes it. A comment has been added to point out the intent clearly to avoid future confusion. Also a comment is fixed that said the opposite of what was actually happening. Signed-off-by:

If a driver supports reading EEPROM but no EEPROM is installed in the system, the driver's get_eeprom_len function returns 0. ethtool will subsequently try to read that zero-length EEPROM anyway. If the driver does not support EEPROM access at all, this operation will return -EOPNOTSUPP. If the driver does support EEPROM access but no EEPROM is installed, the operation will return -EINVAL. Return -EOPNOTSUPP in both cases for consistency. Signed-off-by:

With legacy booting, the platform init code was taking care of the configuring of GPIOs. With device tree based booting, things may or may not work depending what bootloader has configured or if the legacy platform code gets called. Let's add support for the pwrdn and reset GPIOs to the smc91x driver to fix the issues of smc91x not working properly when booted in device tree mode. And let's change n900 to use these settings as some versions of the bootloader do not configure things properly causing errors. Reported-by:

The irq function altera_ps2_rxint returns an irqreturn_t, so use the same type for variable storing the return value. Signed-off-by:

In altera_ps2_close, the data register (offset 0) is written instead of the control register (offset 4), leading to the RX interrupt not being disabled. Fix this by calling writel() with the offset for the proper register. Signed-off-by:

Expression haptic->pwm_dev->period * haptic->magnitude is of type 'unsigned int' and may overflow. We need to convert one of the operands to u64 before multiplying, instead of casting result (potentially overflown) to u64.

Pablo Neira Ayuso says: ==================== netfilter/ipvs fixes for net The following patchset contains fixes for netfilter/ipvs. This round of fixes is larger than usual at this stage, specifically because of the nf_tables bridge reject fixes that I would like to see in 3.18. The patches are: 1) Fix a null-pointer dereference that may occur when logging errors. This problem was introduced by 4a4739d5 ("ipvs: Pull out crosses_local_route_boundary logic") in v3.17-rc5. 2) Update hook mask in nft_reject_bridge so we can also filter out packets from there. This fixes 36d2af59 ("netfilter: nf_tables: allow to filter from prerouting and postrouting"), which needs this chunk to work. 3) Two patches to refactor common code to forge the IPv4 and IPv6 reject packets from the bridge. These are required by the nf_tables reject bridge fix. 4) Fix nft_reject_bridge by avoiding the use of the IP stack to reject packets from the bridge. The idea is to forge the reject packets and inject them to the original port via br_deliver() which is now exported for that purpose. 5) Restrict nft_reject_bridge to bridge prerouting and input hooks. the original skbuff may cloned after prerouting when the bridge stack needs to flood it to several bridge ports, it is too late to reject the traffic. ==================== Signed-off-by:

Restrict the reject expression to the prerouting and input bridge hooks. If we allow this to be used from forward or any other later bridge hook, if the frame is flooded to several ports, we'll end up sending several reject packets, one per cloned packet. Signed-off-by:

If the packet is received via the bridge stack, this cannot reject packets from the IP stack. This adds functions to build the reject packet and send it from the bridge stack. Comments and assumptions on this patch: 1) Validate the IPv4 and IPv6 headers before further processing, given that the packet comes from the bridge stack, we cannot assume they are clean. Truncated packets are dropped, we follow similar approach in the existing iptables match/target extensions that need to inspect layer 4 headers that is not available. This also includes packets that are directed to multicast and broadcast ethernet addresses. 2) br_deliver() is exported to inject the reject packet via bridge localout -> postrouting. So the approach is similar to what we already do in the iptables reject target. The reject packet is sent to the bridge port from which we have received the original packet. 3) The reject packet is forged based on the original packet. The TTL is set based on sysctl_ip_default_ttl for IPv4 and per-net ipv6.devconf_all hoplimit for IPv6. Signed-off-by:

That can be reused by the reject bridge expression to build the reject packet. The new functions are: * nf_reject_ip6_tcphdr_get(): to sanitize and to obtain the TCP header. * nf_reject_ip6hdr_put(): to build the IPv6 header. * nf_reject_ip6_tcphdr_put(): to build the TCP header. Signed-off-by:

These drivers now call ipv6_proxy_select_ident(), which is defined only if CONFIG_INET is enabled. However, they have really depended on CONFIG_INET for as long as they have allowed sending GSO packets from userland. Reported-by:
