This reverts commit 00ee59271777 ("net: fix __netdev_update_features return on ndo_set_features failure") and adds a comment explaining why it's okay to return a value other than 0 upon error. Some drivers might actually change flags and return an error so it's better to fire a spurious notification rather than miss these.

2015-11-17af_unix: take receive queue lock while appending new skbHannes Frederic Sowa1-1/+4

2015-11-17arm64: bpf: make BPF prologue and epilogue align with ARM64 AAPCSYang Shi1-5/+39
Save and restore FP/LR in BPF prog prologue and epilogue, save SP to FP in prologue in order to get the correct stack backtrace. However, ARM64 JIT used FP (x29) as eBPF fp register, FP is subjected to change during function call so it may cause the BPF prog stack base address change too. Use x25 to replace FP as BPF stack base register (fp). Since x25 is callee saved register, so it will keep intact during function call. It is initialized in BPF prog prologue when BPF prog is started to run everytime. Save and restore x25/x26 in BPF prologue and epilogue to keep them intact for the outside of BPF. Actually, x26 is unnecessary, but SP requires 16 bytes alignment. So, the BPF stack layout looks like: high original A64_SP => 0:+-----+ BPF prologue |FP/LR| current A64_FP => -16:+-----+ | ... | callee saved registers +-----+ | | x25/x26 BPF fp register => -80:+-----+ | | | ... | BPF prog stack | | | | current A64_SP => +-----+ | | | ... | Function call stack | | +-----+ low CC: Zi Shen Lim <zlim.lnx@gmail.com> CC: Xi Wang <xi.wang@gmail.com> Signed-off-by: Yang Shi <yang.shi@linaro.org> Acked-by: Zi Shen Lim <zlim.lnx@gmail.com> Signed-off-by: David S.

2015-11-17vlan: Do not put vlan headers back on bridge and macvlan portsVlad Yasevich2-1/+8
When a vlan is configured with REORDER_HEADER set to 0, the vlan header is put back into the packet and makes it appear that the vlan header is still there even after it's been processed. This posses a problem for bridge and macvlan ports. The packets passed to those device may be forwarded and at the time of the forward, vlan headers end up being unexpectedly present. With the patch, we make sure that we do not put the vlan header back (when REORDER_HEADER is 0) if a bridge or macvlan has been configured on top of the vlan device.

2015-11-17vlan: Fix untag operations of stacked vlans with REORDER_HEADER offVlad Yasevich1-1/+2
When we have multiple stacked vlan devices all of which have turned off REORDER_HEADER flag, the untag operation does not locate the ethernet addresses correctly for nested vlans. The reason is that in case of REORDER_HEADER flag being off, the outer vlan headers are put back and the mac_len is adjusted to account for the presense of the header. Then, the subsequent untag operation, for the next level vlan, always use VLAN_ETH_HLEN to locate the begining of the ethernet header and that ends up being a multiple of 4 bytes short of the actuall beginning of the mac header (the multiple depending on the how many vlan encapsulations ethere are). As a reslult, if there are multiple levles of vlan devices with REODER_HEADER being off, the recevied packets end up being dropped. To solve this, we use skb->mac_len as the offset. The value is always set on receive path and starts out as a ETH_HLEN. The value is also updated when the vlan header manupations occur so we know it will be correct.

2015-11-17via-velocity: unconditionally drop frames with bad l2 lengthTimo Teräs1-21/+3
By default the driver allowed incorrect frames to be received. What is worse the code does not handle very short frames correctly. The FCS length is unconditionally subtracted, and the underflow can cause skb_put to be called with large number after implicit cast to unsigned. And indeed, an skb_over_panic() was observed with via-velocity. This removes the module parameter as it does not work in it's current state, and should be implemented via NETIF_F_RXALL if needed.

2015-11-16dl2k: Add support for IP1000A-based cardsOndrej Zary3-6/+69
Add support for IP1000A chips to dl2k driver. IP1000A chip looks like a TC9020 with integrated PHY. This allows IP1000A chips to work reliably because the ipg driver is buggy - it loses packets under load and then completely stops transmitting data. Tested with Asus NX1101 v2.0 at 10, 100 and 1000Mbps: vendor=0x13f0 device=0x1023 (rev 0x41) subsystem vendor=0x1043 device=0x8180 MAC address registers access needed to be changed from 8-bit to 16-bit because 8-bit does not work on IP1000A. 8-bit access is not even allowed in the TC9020 datasheet (although it worked). 16-bit access works on both. Tested that it does not break D-Link DGE-550T (DL-2000 chip, probably a rebranded TC9020): vendor=0x1186 device=0x4000 (rev 0x0c) subsystem vendor=0x1186 device=0x4000 Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: David S.

In case multiple writes to a unix stream socket race we could end up in a situation where we pre-allocate a new skb for use in unix_stream_sendpage but have to free it again in the locked section because another skb has been appended meanwhile, which we must use. Accidentally we didn't clear the pointer after consuming it and so we touched freed memory while appending it to the sk_receive_queue. So, clear the pointer after consuming the skb.

2015-11-16bpf, arm64: start flushing icache range from headerDaniel Borkmann1-1/+1
While recently going over ARM64's BPF code, I noticed that the icache range we're flushing should start at header already and not at ctx.image. Reason is that after b569c1c622c5 ("net: bpf: arm64: address randomize and write protect JIT code"), we also want to make sure to flush the random-sized trap in front of the start of the actual program (analogous to x86). No operational differences from user side.

2015-11-16bpf: samples: exclude asm/sysreg.h for arm64Yang Shi1-2/+5
commit 338d4f49d6f7114a017d294ccf7374df4f998edc ("arm64: kernel: Add support for Privileged Access Never") includes sysreg.h into futex.h and uaccess.h. But, the inline assembly used by asm/sysreg.h is incompatible with llvm so it will cause BPF samples build failure for ARM64. Since sysreg.h is useless for BPF samples, just exclude it from Makefile via defining __ASM_SYSREG_H.

2015-11-16arm64: bpf: fix JIT frame pointer setupYang Shi1-3/+3
BPF fp should point to the top of the BPF prog stack. The original implementation made it point to the bottom incorrectly. Move A64_SP to fp before reserve BPF prog stack space.
