Currently, iflink of the parent interface was always accessed, even when interface didn't have a parent and hence we crashed there. Handle the interface types properly: for a child interface, return the ifindex of the parent, for parent interface, return its ifindex. For child devices, make sure to set the parent pointer prior to invoking register_netdevice(), this allows the new ndo to be called by the stack immediately after the child device is registered.

Fix bug which occurs when more than <limit> packets are available during napi-poll, leading to "delays" and retransmissions on the network. Check for (count < limit) before checking the get_rx_status in tse_rx-function. Function get_rx_status is reading from the response-fifo. If there is currently a response in the fifo, reading the last byte of the response pops the value from the fifo. If the limit is checked as second condition and the limit is reached the fifo is popped but the packet is not processed. Signed-off-by: Andreas Oetken <ennoerlangen@gmail.com> Signed-off-by: David S.

In commit 04ffcb25 ("net: Add ndo_gso_check") Tom originally added the 'dev' argument to be able to call ndo_gso_check(). Then later, when generalizing this in commit 5f35227e ("net: Generalize ndo_gso_check to ndo_features_check") Jesse removed the call to ndo_gso_check() in netif_needs_gso() by calling the new ndo_features_check() in a different place. This made the 'dev' argument unused. Remove the unused argument and go back to the code as before.

When you redirect a VLAN device to any device, you end up with crap in af_packet on the xmit path because hard_header_len is not equal to skb->mac_len. So the redirected packet contains four extra bytes at the start which then gets interpreted as part of the MAC address. This patch fixes this by only pushing skb->mac_len. We also need to fix ifb because it tries to undo the pushing done by act_mirred.

Two different problems are fixed here : 1) inet_sk_diag_fill() might be called without socket lock held. icsk->icsk_ca_ops can change under us and module be unloaded. -> Access to freed memory. Fix this using rcu_read_lock() to prevent module unload. 2) Some TCP Congestion Control modules provide information but again this is not safe against icsk->icsk_ca_ops change and nla_put() errors were ignored. Some sockets could not get the additional info if skb was almost full. Fix this by returning a status from get_info() handlers and using rcu protection as well.

Sure. PS I used the wrong email for James the first time around. So let me repeat the question here. Should secmark be preserved or cleared across tunnels within the same name space? In fact, do our security models even support name spaces? ---8<--- The commit ea23192e ("tunnels: harmonize cleanup done on skb on rx path") broke anyone trying to use netfilter marking across IPv4 tunnels.

1. first bug is a silly mistake. It broke tracing examples and prevented simple bpf programs from loading. In the following code: if (insn->imm == 0 && BPF_SIZE(insn->code) == BPF_W) { } else if (...) { // this part should have been executed when // insn->code == BPF_W and insn->imm != 0 } Obviously it's not doing that. So simple instructions like: r2 = *(u64 *)(r1 + 8) will be rejected. Note the comments in the code around these branches were and still valid and indicate the true intent. Replace it with: if (BPF_SIZE(insn->code) != BPF_W) continue; if (insn->imm == 0) { } else if (...) { // now this code will be executed when // insn->code == BPF_W and insn->imm != 0 } 2. second bug is more subtle. If malicious code is using the same dest register as source register, the checks designed to prevent the same instruction to be used with different pointer types will fail to trigger, since we were assigning src_reg_type when it was already overwritten by check_mem_access(). The fix is trivial. Just move line: src_reg_type = regs[insn->src_reg].type; before check_mem_access(). Add new 'access skb fields bad4' test to check this case.

For the short-term solution, lets fix bpf helper functions to use skb->mac_header relative offsets instead of skb->data in order to get the same eBPF programs with cls_bpf and act_bpf work on ingress and egress qdisc path. We need to ensure that mac_header is set before calling into programs. This is effectively the first option from below referenced discussion. More long term solution for LD_ABS|LD_IND instructions will be more intrusive but also more beneficial than this, and implemented later as it's too risky at this point in time. I.e., we plan to look into the option of moving skb_pull() out of eth_type_trans() and into netif_receive_skb() as has been suggested as second option. Meanwhile, this solution ensures ingress can be used with eBPF, too, and that we won't run into ABI troubles later. For dealing with negative offsets inside eBPF helper functions, we've implemented bpf_skb_clone_unwritable() to test for unwriteable headers.

Vince Bridgers says: ==================== stmmac: Correct flow control configuration This series of patches corrects flow control configuration for the Synopsys GMAC driver. Flow control is configured based on a configurable receive fifo size. If less than 4Kbytes flow control is left disabled and a warning is presented. If a receive fifo size is not specified, flow control is left disabled to maintain current behavior. Unicast pause detection was disabled, but is now enabled. The pause time was modified to be maximum time per a XON/XOFF flow control mode of operation. This patch was tested on an Altera Cyclone 5 and an Altera Arria 10 devkit, and verified that flow control operates as expected when enabled. Please consider this series for inclusion so that flow control will function as expected for the Synopsys GMAC controller. ==================== Acked-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: David S.

set_filter_wr is requesting __GFP_NOFAIL allocation although it can return ENOMEM without any problems obviously (t4_l2t_set_switching does that already). So the non-failing requirement is too strong without any obvious reason. Drop __GFP_NOFAIL and reorganize the code to have the failure paths easier. The same applies to _c4iw_write_mem_dma_aligned which uses __GFP_NOFAIL and then checks the return value and returns -ENOMEM on failure. This doesn't make any sense what so ever. Either the allocation cannot fail or it can. del_filter_wr seems to be safe as well because the filter entry is not marked as pending and the return value is propagated up the stack up to c4iw_destroy_listen.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-04-14 This series contains updates to i40e and i40evf. Mitch provides a fix for i40e, where VFs were gone and the associated VSI's had been removed and the rings were not stopped, which in some circumstances cased memory corruption or DMAR errors. So stop all the rings associated with each VF before releasing its resources. Also cleaned up a poorly indented piece of code. Fixes VF link state, where VF devices were assuming link is up unless told otherwise, which means that VFs instantiated on a PF with no link, would report the wrong state. Anjali adds support to add Flow director Sideband rules for a VF from it's PF. Fixes a recently discovered hardware issue, where after a VFLR hardware might be indicating to us a reset completion little too early, so wait another 10 msec for cache to be cleaned up. Jesse enables the user to dump the internal hardware state for better debugging by allowing a bash script to acquire information about the internal hardware state. The data output to the kernel log is collected by the script and can then be sent to Intel. Also fixed a possible failure path to allocate memory that was found by smatch. Cleaned up unused local variables. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Commit 9a2620c8 ("bnx2x: prevent WARN during driver unload") switched the napi/busy_lock locking mechanism from spin_lock() into spin_lock_bh(), breaking inter-operability with netconsole, as netpoll disables interrupts prior to calling our napi mechanism. This switches the driver into using atomic assignments instead of the spinlock mechanisms previously employed. Based on initial patch from Yuval Mintz & Ariel Elior I basically added softirq starvation avoidance, and mixture of atomic operations, plain writes and barriers. Note this slightly reduces the overhead for this driver when no busy_poll sockets are in use.

The code sets the expiry value of the timer to a relative value and starts it with hrtimer_start_expires. That's fine, but that only works once. The timer is started in relative mode, so the expiry value gets overwritten with the absolut expiry time (now + expiry). So once the timer expired, a new call to hrtimer_start_expires results in an immidiately expired timer, because the expiry value is already in the past. Use the proper mechanisms to (re)start the timer in the intended way. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Cc: "David S.

Pull networking updates from David Miller: 1) Add BQL support to via-rhine, from Tino Reichardt. 2) Integrate SWITCHDEV layer support into the DSA layer, so DSA drivers can support hw switch offloading. From Floria Fainelli. 3) Allow 'ip address' commands to initiate multicast group join/leave, from Madhu Challa. 4) Many ipv4 FIB lookup optimizations from Alexander Duyck. 5) Support EBPF in cls_bpf classifier and act_bpf action, from Daniel Borkmann. 6) Remove the ugly compat support in ARP for ugly layers like ax25, rose, etc. And use this to clean up the neigh layer, then use it to implement MPLS support. All from Eric Biederman. 7) Support L3 forwarding offloading in switches, from Scott Feldman. 8) Collapse the LOCAL and MAIN ipv4 FIB tables when possible, to speed up route lookups even further. From Alexander Duyck. 9) Many improvements and bug fixes to the rhashtable implementation, from Herbert Xu and Thomas Graf. In particular, in the case where an rhashtable user bulk adds a large number of items into an empty table, we expand the table much more sanely. 10) Don't make the tcp_metrics hash table per-namespace, from Eric Biederman. 11) Extend EBPF to access SKB fields, from Alexei Starovoitov. 12) Split out new connection request sockets so that they can be established in the main hash table. Much less false sharing since hash lookups go direct to the request sockets instead of having to go first to the listener then to the request socks hashed underneath.

Pull ARM updates from Russell King: "Included in this update are both some long term fixes and some new features. Fixes: - An integer overflow in the calculation of ELF_ET_DYN_BASE. - Avoiding OOMs for high-order IOMMU allocations - SMP requires the data cache to be enabled for synchronisation primitives to work, so prevent the CPU_DCACHE_DISABLE option being visible on SMP builds. - A bug going back 10+ years in the noMMU ARM94* CPU support code, where it corrupts registers. Found by folk getting Linux running on their cameras. - Versatile Express needs an errata workaround enabled for CPU hot-unplug to work. Features: - Clean up module linker by handling out of range relocations separately from relocation cases we don't handle. - Fix a long term bug in the pci_mmap_page_range() code, which we hope won't impact userspace (we hope there's no users of the existing broken interface.) - Don't map DMA coherent allocations when we don't have a MMU. - Drop experimental status for SMP_ON_UP. - Warn when DT doesn't specify ePAPR mandatory cache properties. - Add documentation concerning how we find the start of physical memory for AUTO_ZRELADDR kernels, detailing why we have chosen the mask and the implications of changing it. - Updates from Ard Biesheuvel to address some issues with large kernels (such as allyesconfig) failing to link. - Allow hibernation to work on modern (ARMv7) CPUs - this appears to have never worked in the past on these CPUs. - Enable IRQ_SHOW_LEVEL, which changes the /proc/interrupts output format (hopefully without userspace breaking... let's hope that if it causes someone a problem, they tell us.) - Fix tegra-ahb DT offsets. - Rework ARM errata 643719 code (and ARMv7 flush_cache_louis()/ flush_dcache_all()) code to be more efficient, and enable this errata workaround by default for ARMv7+SMP CPUs. This complements the Versatile Express fix above. - Rework ARMv7 context code for errata 430973, so that only Cortex A8 CPUs are impacted by the branch target buffer flush when this errata is enabled. Also update the help text to indicate that all r1p* A8 CPUs are impacted. - Switch ARM to the generic show_mem() implementation, it conveys all the information which we were already reporting. - Prevent slow timer sources being used for udelay() - timers running at less than 1MHz are not useful for this, and can cause udelay() to return immediately, without any wait. Using such a slow timer is silly. - VDSO support for 32-bit ARM, mainly for gettimeofday() using the ARM architected timer. - Perf support for Scorpion performance monitoring units" vdso semantic conflict fixed up as per linux-next. * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (52 commits) ARM: update errata 430973 documentation to cover Cortex A8 r1p* ARM: ensure delay timer has sufficient accuracy for delays ARM: switch to use the generic show_mem() implementation ARM: proc-v7: avoid errata 430973 workaround for non-Cortex A8 CPUs ARM: enable ARM errata 643719 workaround by default ARM: cache-v7: optimise test for Cortex A9 r0pX devices ARM: cache-v7: optimise branches in v7_flush_cache_louis ARM: cache-v7: consolidate initialisation of cache level index ARM: cache-v7: shift CLIDR to extract appropriate field before masking ARM: cache-v7: use movw/movt instructions ARM: allow 16-bit instructions in ALT_UP() ARM: proc-arm94*.S: fix setup function ARM: vexpress: fix CPU hotplug with CT9x4 tile.

These changes just remove unused variables and any code that uses them as the results of storing into these variables doesn't have any side effects that I can see or provide any benefit.
