The u-blox TOBY-L2 is a LTE Cat 4 module with HSPA+ and 2G fallback. This module allows switching to different USB profiles with the 'AT+UUSBCONF' command, and provides a ECM network interface when the 'AT+UUSBCONF=2' profile is selected. The u-blox SARA-U2 is a HSPA module with 2G fallback. The default USB configuration includes a ECM network interface. Both these modules are controlled via AT commands through one of the TTYs exposed. Connecting these modules may be done just by activating the desired PDP context with 'AT+CGACT=1,<cid>' and then running DHCP on the ECM interface.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2017-10-09 This series contains updates to ixgbe and arch/Kconfig. Mark fixes a case where PHY register access is not supported and we were returning a PHY address, when we should have been returning -EOPNOTSUPP. Sabrina Dubroca fixes the use of a logical "and" when it should have been the bitwise "and" operator. Ding Tianhong reverts the commit that added the Kconfig bool option ARCH_WANT_RELAX_ORDER, since there is now a new flag PCI_DEV_FLAGS_NO_RELAXED_ORDERING that has been added to indicate that Relaxed Ordering Attributes should not be used for Transaction Layer Packets. Then follows up with making the needed changes to ixgbe to use the new PCI_DEV_FLAGS_NO_RELAXED_ORDERING flag. John Fastabend fixes an issue in the ring accounting when the transmit ring parameters are changed via ethtool when an XDP program is attached. ==================== Signed-off-by: David S.

The commit bc044e8d ("udp: perform source validation for mcast early demux") does not take into account that broadcast packets lands in the same code path and they need different checks for the source address - notably, zero source address are valid for bcast and invalid for mcast. As a result, 2nd and later broadcast packets with 0 source address landing to the same socket are dropped. This breaks dhcp servers. Since we don't have stringent performance requirements for ingress broadcast traffic, fix it by disabling UDP early demux such traffic.

It turns out that multiple places can call netlink_dump(), which means it's still possible to dereference partially initialized values in dump() that were the result of a faulty returned start(). This fixes the issue by calling start() _before_ setting cb_running to true, so that there's no chance at all of hitting the dump() function through any indirect paths. It also moves the call to start() to be when the mutex is held. This has the nice side effect of serializing invocations to start(), which is likely desirable anyway. It also prevents any possible other races that might come out of this logic. In testing this with several different pieces of tricky code to trigger these issues, this commit fixes all avenues that I'm aware of. Signed-off-by: Jason A.

Merge tag 'mac80211-for-davem-2017-10-09' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211 Johannes Berg says: ==================== pull-request: mac80211 2017-10-09 The QCA folks found another netlink problem - we were missing validation of some attributes. It's not super problematic since one can only read a few bytes beyond the message (and that memory must exist), but here's the fix for it. I thought perhaps we can make nla_parse_nested() require a policy, but given the two-stage validation/parsing in regular netlink that won't work.

A recent patch removed the dst_free() on the allocated dst_entry in ipv4_blackhole_route(). The dst_free() marked the dst_entry as dead and added it to the gc list. I.e. it was setup for a one time usage. As a result we may now have a blackhole route cached at a socket on some IPsec scenarios. This makes the connection unusable. Fix this by marking the dst_entry directly at allocation time as 'dead', so it is used only once.

The new flag PCI_DEV_FLAGS_NO_RELAXED_ORDERING has been added to indicate that Relaxed Ordering Attributes (RO) should not be used for Transaction Layer Packets (TLP) targeted toward these affected Root Port, it will clear the bit4 in the PCIe Device Control register, so the PCIe device drivers could query PCIe configuration space to determine if it can send TLPs to Root Port with the Relaxed Ordering Attributes set. With this new flag we don't need the config ARCH_WANT_RELAX_ORDER to control the Relaxed Ordering Attributes for the ixgbe drivers just like the commit 1a8b6d76 ("net:add one common config...") did, so revert this commit.

Commit 2c16d603 ("netfilter: xt_bpf: support ebpf") introduced support for attaching an eBPF object by an fd, with the 'bpf_mt_check_v1' ABI expecting the '.fd' to be specified upon each IPT_SO_SET_REPLACE call. However this breaks subsequent iptables calls: # iptables -A INPUT -m bpf --object-pinned /sys/fs/bpf/xxx -j ACCEPT # iptables -A INPUT -s 5.6.7.8 -j ACCEPT iptables: Invalid argument. Run `dmesg' for more information. That's because iptables works by loading existing rules using IPT_SO_GET_ENTRIES to userspace, then issuing IPT_SO_SET_REPLACE with the replacement set. However, the loaded 'xt_bpf_info_v1' has an arbitrary '.fd' number (from the initial "iptables -m bpf" invocation) - so when 2nd invocation occurs, userspace passes a bogus fd number, which leads to 'bpf_mt_check_v1' to fail. One suggested solution [1] was to hack iptables userspace, to perform a "entries fixup" immediatley after IPT_SO_GET_ENTRIES, by opening a new, process-local fd per every 'xt_bpf_info_v1' entry seen. However, in [2] both Pablo Neira Ayuso and Willem de Bruijn suggested to depricate the xt_bpf_info_v1 ABI dealing with pinned ebpf objects. This fix changes the XT_BPF_MODE_FD_PINNED behavior to ignore the given '.fd' and instead perform an in-kernel lookup for the bpf object given the provided '.path'. It also defines an alias for the XT_BPF_MODE_FD_PINNED mode, named XT_BPF_MODE_PATH_PINNED, to better reflect the fact that the user is expected to provide the path of the pinned object. Existing XT_BPF_MODE_FD_ELF behavior (non-pinned fd mode) is preserved.

When a bundling message is received, the function tipc_link_input() calls function tipc_msg_extract() to unbundle all inner messages of the bundling message before adding them to input queue. The function tipc_msg_extract() just clones all inner skb for all inner messagges from the bundling skb. This means that the skb headroom of an inner message overlaps with the data part of the preceding message in the bundle. If the message in question is a name addressed message, it may be subject to a secondary destination lookup, and eventually be sent out on one of the interfaces again. But, since what is perceived as headroom by the device driver in reality is the last bytes of the preceding message in the bundle, the latter will be overwritten by the MAC addresses of the L2 header. If the preceding message has not yet been consumed by the user, it will evenually be delivered with corrupted contents. This commit fixes this by uncloning all messages passing through the function tipc_msg_lookup_dest(), hence ensuring that the headroom is always valid when the message is passed on.

We change the initialization of the skb transmit buffer queues in the functions tipc_bcast_xmit() and tipc_rcast_xmit() to also initialize their spinlocks.

In commit fc922bb0 ("mlxsw: spectrum_router: Use one LPM tree for all virtual routers") I increased the scale of supported VRFs by having all of them share the same LPM tree. In order to avoid look-ups for prefix lengths that don't exist, each route removal would trigger an aggregation across all the active virtual routers to see which prefix lengths are in use and which aren't and structure the tree accordingly. With the way the data structures are currently laid out, this is a very expensive operation. When preformed repeatedly - due to the invocation of the abort mechanism - and with enough VRFs, this can result in a hung task. For now, avoid this optimization until it can be properly re-added in net-next.

while processing Rx = Ry instruction the verifier does regs[insn->dst_reg] = regs[insn->src_reg] which often clears write mark (when Ry doesn't have it) that was just set by check_reg_arg(Rx) prior to the assignment. That causes mark_reg_read() to keep marking Rx in this block as REG_LIVE_READ (since the logic incorrectly misses that it's screened by the write) and in many of its parents (until lucky write into the same Rx or beginning of the program). That causes is_state_visited() logic to miss many pruning opportunities. Furthermore mark_reg_read() logic propagates the read mark for BPF_REG_FP as well (though it's readonly) which causes harmless but unnecssary work during is_state_visited(). Note that do_propagate_liveness() skips FP correctly, so do the same in mark_reg_read() as well.

Commit 35e015e1 ("ipv6: fix net.ipv6.conf.all interface DAD handlers") was intended to affect accept_dad flag handling in such a way that DAD operation and mode on a given interface would be selected according to the maximum value of conf/{all,interface}/accept_dad. However, addrconf_dad_begin() checks for particular cases in which we need to skip DAD, and this check was modified in the wrong way. Namely, it was modified so that, if the accept_dad flag is 0 for the given interface *or* for all interfaces, DAD would be skipped. We have instead to skip DAD if accept_dad is 0 for the given interface *and* for all interfaces.

ppp_release() tries to ensure that netdevices are unregistered before decrementing the unit refcount and running ppp_destroy_interface(). This is all fine as long as the the device is unregistered by ppp_release(): the unregister_netdevice() call, followed by rtnl_unlock(), guarantee that the unregistration process completes before rtnl_unlock() returns. However, the device may be unregistered by other means (like ppp_nl_dellink()). If this happens right before ppp_release() calling rtnl_lock(), then ppp_release() has to wait for the concurrent unregistration code to release the lock. But rtnl_unlock() releases the lock before completing the device unregistration process. This allows ppp_release() to proceed and eventually call ppp_destroy_interface() before the unregistration process completes. Calling free_netdev() on this partially unregistered device will BUG(): ------------[ cut here ]------------ kernel BUG at net/core/dev.c:8141! invalid opcode: 0000 [#1] SMP CPU: 1 PID: 1557 Comm: pppd Not tainted 4.14.0-rc2+ #4 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.10.2-1.fc26 04/01/2014 Call Trace: ppp_destroy_interface+0xd8/0xe0 [ppp_generic] ppp_disconnect_channel+0xda/0x110 [ppp_generic] ppp_unregister_channel+0x5e/0x110 [ppp_generic] pppox_unbind_sock+0x23/0x30 [pppox] pppoe_connect+0x130/0x440 [pppoe] SYSC_connect+0x98/0x110 ? do_fcntl+0x2c0/0x5d0 SyS_connect+0xe/0x10 entry_SYSCALL_64_fastpath+0x1a/0xa5 RIP: free_netdev+0x107/0x110 RSP: ffffc28a40573d88 ---[ end trace ed294ff0cc40eeff ]--- We could set the ->needs_free_netdev flag on PPP devices and move the ppp_destroy_interface() logic in the ->priv_destructor() callback.

There are three important fields that indicate the overall health and status of an array: dev_health, sync_ratio, and sync_action. They tell us the condition of the devices in the array, and the degree to which the array is synchronized. This commit fixes a condition that is reported incorrectly. When a member of the array is being rebuilt or a new device is added, the "recover" process is used to synchronize it with the rest of the array. When the process is complete, but the sync thread hasn't yet been reaped, it is possible for the state of MD to be: mddev->recovery = [ MD_RECOVERY_RUNNING MD_RECOVERY_RECOVER MD_RECOVERY_DONE ] curr_resync_completed = <max dev size> (but not MaxSector) and all rdevs to be In_sync. This causes the 'array_in_sync' output parameter that is passed to rs_get_progress() to be computed incorrectly and reported as 'false' -- or not in-sync. This in turn causes the dev_health status characters to be reported as all 'a', rather than the proper 'A'. This can cause erroneous output for several seconds at a time when tools will want to be checking the condition due to events that are raised at the end of a sync process. Fix this by properly calculating the 'array_in_sync' return parameter in rs_get_progress(). Also, remove an unnecessary intermediate 'recovery_cp' variable in rs_get_progress().

If the vlan is down, free the packet instead of proceeding with other processing, or counting it as received. If vlan interfaces are used as slaves for bonding, with arp monitoring for connectivity, if the rx counter is seen to be incrementing, then the bond device will not observe that the interface is down.

Pull ARM SoC fixes from Olof Johansson: "Our first batch of fixes this release cycle, unfortunately a bit noisier than usual. Two major groups stand out: - Some pinctril dts/dtsi changes for stm32 due to a new driver being merged during the merge window, and this aligns the DT contents between the old format and the new. This could arguably be moved to the next merge window but it also seemed relatively harmless to include now. - Amlogic/meson had driver changes merged that required devicetree changes to avoid functional/performance regressions. I've already asked them to be more careful about this going forward, and making sure drivers are compatible with older DTs when they make these kind of changes. The platform is actively being upstreamed so there's a few things in flight, we've seen this happen before and sometimes it's hard to catch in time. Besides that there is the usual mix of minor fixes" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (33 commits) ARM: dts: stm32: use right pinctrl compatible for stm32f469 ARM: dts: stm32: Fix STMPE1600 binding on stm32429i-eval board ARM: defconfig: update Gemini defconfig ARM: defconfig: FRAMEBUFFER_CONSOLE can no longer be =m arm64: dts: rockchip: add the grf clk for dw-mipi-dsi on rk3399 reset: Restrict RESET_HSDK to ARC_SOC_HSDK or COMPILE_TEST ARM: dts: da850-evm: add serial and ethernet aliases ARM: dts: am43xx-epos-evm: Remove extra CPSW EMAC entry ARM: dts: am33xx: Add spi alias to match SOC schematics ARM: OMAP2+: hsmmc: fix logic to call either omap_hsmmc_init or omap_hsmmc_late_init but not both ARM: dts: dra7: Set a default parent to mcasp3_ahclkx_mux ARM: OMAP2+: dra7xx: Set OPT_CLKS_IN_RESET flag for gpio1 ARM: dts: nokia n900: drop unneeded/undocumented parts of the dts arm64: dts: rockchip: Correct MIPI DPHY PLL clock on rk3399 arm64: dt marvell: Fix AP806 system controller size MAINTAINERS: add Macchiatobin maintainers entry ARC: reset: remove the misleading v1 suffix all over ARC: reset: add missing DT binding documentation for HSDKv1 reset driver ARC: reset: Only build on archs that have IOMEM ARM: at91: Replace uses of virt_to_phys with __pa_symbol ...
