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:

A recent flaw in the netdev feature setting resulted in warnings like this one from VLAN interfaces: WARNING: CPU: 1 PID: 4975 at net/core/dev.c:2419 skb_warn_bad_offload+0xbc/0xcb() : caps=(0x00000000001b5820, 0x00000000001b5829) len=2782 data_len=0 gso_size=1348 gso_type=16 ip_summed=3 The ":" is supposed to be preceded by a driver name, but in this case it is an empty string since the device has no parent. There are many types of network devices without a parent. The anonymous warnings for these devices can be hard to debug. Log the network device name instead in these cases to assist further debugging. This is mostly similar to how __netdev_printk() handles orphan devices. Signed-off-by:

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. This bug has been found with syzkaller (http://github.com/google/syzkaller) by Dmitry Vyukov. Fixes: 869e7c62 ("net: af_unix: implement stream sendpage support") Reported-by:

If ndo_set_features fails __netdev_update_features() will return -1 but this is wrong because it is expected to return 0 if no features were changed (see netdev_update_features()), which will cause a netdev notifier to be called without any actual changes.

When __netdev_update_features() was updated to ensure some features are disabled on new lower devices, an error was introduced for devices which don't have the ndo_set_features() method set. Before we'll just set the new features, but now we return an error and don't set them. Fix this by returning the old behaviour and setting err to 0 when ndo_set_features is not present.

On certain hardware after software reboot the chip may get stuck and fail to reinitialize during reset. This can be fixed by ensuring that PHY is reset too. Old PHY resetting method required operational MDIO interface, therefore the chip should have been already set up. In order to be able to function during probe, it is changed to use PMT_CTRL register. The problem could be observed on SMDK5410 board. Signed-off-by:

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 b569c1c6 ("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. Signed-off-by:

commit a70587b3 ("ath10k: configure copy engine 5 for HTT messages") moved send completion polling under HTT Rx (CE 5) service routine. For QCA6174 based devices copy engine 1 (CE 1) is used for HTT Rx instead of CE 5. So send completion never be called. This is causing "failed to transmit packet, dropping: -105" errors. Fix this by processing send completion from CE 1 service routine instead of CE 5. Fixes: a70587b3 ("ath10k: configure copy engine 5 for HTT messages") Tested-by:

commit 338d4f49 ("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. Signed-off-by:

Drivers like vxlan use the recently introduced udp_tunnel_xmit_skb/udp_tunnel6_xmit_skb APIs. udp_tunnel6_xmit_skb makes use of ip6tunnel_xmit, and ip6tunnel_xmit, after sending the packet, updates the struct stats using the usual u64_stats_update_begin/end calls on this_cpu_ptr(dev->tstats). udp_tunnel_xmit_skb makes use of iptunnel_xmit, which doesn't touch tstats, so drivers like vxlan, immediately after, call iptunnel_xmit_stats, which does the same thing - calls u64_stats_update_begin/end on this_cpu_ptr(dev->tstats). While vxlan is probably fine (I don't know?), calling a similar function from, say, an unbound workqueue, on a fully preemptable kernel causes real issues: [ 188.434537] BUG: using smp_processor_id() in preemptible [00000000] code: kworker/u8:0/6 [ 188.435579] caller is debug_smp_processor_id+0x17/0x20 [ 188.435583] CPU: 0 PID: 6 Comm: kworker/u8:0 Not tainted 4.2.6 #2 [ 188.435607] Call Trace: [ 188.435611] [<ffffffff8234e936>] dump_stack+0x4f/0x7b [ 188.435615] [<ffffffff81915f3d>] check_preemption_disabled+0x19d/0x1c0 [ 188.435619] [<ffffffff81915f77>] debug_smp_processor_id+0x17/0x20 The solution would be to protect the whole this_cpu_ptr(dev->tstats)/u64_stats_update_begin/end blocks with disabling preemption and then reenabling it.
