Now SYN_RECV request sockets are installed in ehash table, an ICMP handler can find a request socket while another cpu handles an incoming packet transforming this SYN_RECV request socket into an ESTABLISHED socket. We need to remove the now obsolete WARN_ON(req->sk), since req->sk is set when a new child is created and added into listener accept queue. If this race happens, the ICMP will do nothing special.

David Daney says: ==================== net/phy: Fixes for Cavium Thunder MDIO code. Previous patch set: commit 5fc7cf17 ("net: thunderx: Cleanup PHY probing code.") commit 1eefee90 ("phy: mdio-octeon: Refactor into two files/modules") commit 379d7ac7 ("phy: mdio-thunder: Add driver for Cavium Thunder SoC MDIO buses.") Had several problems. We try to fix them here. ==================== Signed-off-by:

It is possible, although unlikely, that probing will find the phy_device for the first LMAC of a thunder BGX device, but then need to fail with -EPROBE_DEFER on a subsequent LMAC. In this case, we need to call put_device() on each of the phy_devices that were obtained, but will be unused due to returning -EPROBE_DEFER. Also, since we can break out of the probing loop early, we need to explicitly call of_node_put() outside of the loop. Signed-off-by:

Locking ppp_mutex must be done before dereferencing file->private_data, otherwise it could be modified before ppp_unattached_ioctl() takes the lock. This could lead ppp_unattached_ioctl() to override ->private_data, thus leaking reference to the ppp_file previously pointed to. v2: lock all ppp_ioctl() instead of just checking private_data in ppp_unattached_ioctl(), to avoid ambiguous behaviour.

This patch adds the emac device node for rk3036 SoCs. We need to let mac clock under the DPLL which is able to provide the accurate 50MHz what mac_ref need, since that will cause some unstable things if the cpufreq is working. Signed-off-by:

The emac needs constant and very specific rate but the possible PLL-sources are very limited, so we expect the PLL source to be set manually on per board and don't want it to get changed in an automatic way later. So add the necessary clock-id and disable reparenting on set_rate calls. Signed-off-by:

This patch adds the following property for arc_emac. 1) phy-reset-gpios: The phy-reset-gpio is an optional property for arc emac device tree boot. Change the binding document to match the driver code. 2) phy-reset-duration: Different boards may require different phy reset duration. Add property phy-reset-duration for device tree probe, so that the boards that need a longer reset duration can specify it in their device tree. Anyway, we can add the above property for arc emac.

When the ETHTOOL_GLINKSETTINGS implementation finds that userland is using the wrong number of words of link mode bitmaps (or is trying to find out the right numbers) it sets the cmd field to 0 in the response structure.

Iff sh_eth_phy_start() call fails in sh_eth_open(), the netif_start_queue() call done by sh_eth_dev_init() is not undone. In order to deal with that, stop calling netif_start_queue() from there, so that it can be called only when the device is fully opened and sh_eth_dev_init() only deals with the hardware initialization, symmetrically to sh_eth_dev_exit()...

When driver has hit a parity event, HW can no longer write to host memory. As a result, Tx completions cannot be written to the host SB memory, and waiting for Tx completions eventually timeout. As driver is willing to delay as much as 1-2 seconds per Tx queue for its draining and this delay is sequential, the time to recover might greatly lengthen needlessly in case the recovery is done under multi-connection traffic.

Pablo Neira Ayuso says: ==================== Netfilter/IPVS/OVS updates for net-next The following patchset contains Netfilter/IPVS fixes and OVS NAT support, more specifically this batch is composed of: 1) Fix a crash in ipset when performing a parallel flush/dump with set:list type, from Jozsef Kadlecsik. 2) Make sure NFACCT_FILTER_* netlink attributes are in place before accessing them, from Phil Turnbull. 3) Check return error code from ip_vs_fill_iph_skb_off() in IPVS SIP helper, from Arnd Bergmann. 4) Add workaround to IPVS to reschedule existing connections to new destination server by dropping the packet and wait for retransmission of TCP syn packet, from Julian Anastasov. 5) Allow connection rescheduling in IPVS when in CLOSE state, also from Julian. 6) Fix wrong offset of SIP Call-ID in IPVS helper, from Marco Angaroni. 7) Validate IPSET_ATTR_ETHER netlink attribute length, from Jozsef. 8) Check match/targetinfo netlink attribute size in nft_compat, patch from Florian Westphal. 9) Check for integer overflow on 32-bit systems in x_tables, from Florian Westphal. Several patches from Jarno Rajahalme to prepare the introduction of NAT support to OVS based on the Netfilter infrastructure: 10) Schedule IP_CT_NEW_REPLY definition for removal in nf_conntrack_common.h. 11) Simplify checksumming recalculation in nf_nat. 12) Add comments to the openvswitch conntrack code, from Jarno. 13) Update the CT state key only after successful nf_conntrack_in() invocation. 14) Find existing conntrack entry after upcall. 15) Handle NF_REPEAT case due to templates in nf_conntrack_in(). 16) Call the conntrack helper functions once the conntrack has been confirmed. 17) And finally, add the NAT interface to OVS. The batch closes with: 18) Cleanup to use spin_unlock_wait() instead of spin_lock()/spin_unlock(), from Nicholas Mc Guire. ==================== Signed-off-by: -

The smc91x driver defines a macro that compares its argument to itself, apparently to get a true result while using its argument to avoid a warning about unused local variables. Unfortunately, this triggers a warning with gcc-6, as the comparison is obviously useless: drivers/net/ethernet/smsc/smc91x.c: In function 'smc_hardware_send_pkt': drivers/net/ethernet/smsc/smc91x.c:563:14: error: self-comparison always evaluates to true [-Werror=tautological-compare] if (!smc_special_trylock(&lp->lock, flags)) { This replaces the macro with another one that behaves similarly, with a cast to (void) to ensure the argument is used, and using a literal 'true' as its value.

Extend OVS conntrack interface to cover NAT. New nested OVS_CT_ATTR_NAT attribute may be used to include NAT with a CT action. A bare OVS_CT_ATTR_NAT only mangles existing and expected connections. If OVS_NAT_ATTR_SRC or OVS_NAT_ATTR_DST is included within the nested attributes, new (non-committed/non-confirmed) connections are mangled according to the rest of the nested attributes. The corresponding OVS userspace patch series includes test cases (in tests/system-traffic.at) that also serve as example uses. This work extends on a branch by Thomas Graf at https://github.com/tgraf/ovs/tree/nat. Signed-off-by:

Add a new function ovs_ct_find_existing() to find an existing conntrack entry for which this packet was already applied to. This is only to be called when there is evidence that the packet was already tracked and committed, but we lost the ct reference due to an userspace upcall. ovs_ct_find_existing() is called from skb_nfct_cached(), which can now hide the fact that the ct reference may have been lost due to an upcall. This allows ovs_ct_commit() to be simplified. This patch is needed by later "openvswitch: Interface with NAT" patch, as we need to be able to pass the packet through NAT using the original ct reference also after the reference is lost after an upcall.
