Sending ICMP packets with raw sockets ends up in the SNMP counters logging the type as the first byte of the IPv4 header rather than the ICMP header. This is fixed by adding the IP Header Length to the casting into a icmphdr struct. Signed-off-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. Fix this by returning 0 if ndo_set_features fails. Fixes: 6cb6a27c ("net: Call netdev_features_change() from netdev_update_features()") CC: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by:

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 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.

When cleaning slave's counter resources, we hold a spinlock that protects the slave's counters list. As part of the clean, we call __mlx4_clear_if_stat which calls mlx4_alloc_cmd_mailbox which is a sleepable function. In order to fix this issue, hold the spinlock, and copy all counter indices into a temporary array, and release the spinlock. Afterwards, iterate over this array and free every counter. Repeat this scenario until the original list is empty (a new counter might have been added while releasing the counters from the temporary array).

Prevent outgoing multicast frames from looping back to the RX queue. By introducing new HW capability self_lb_en_modifiable, which indicates the support to modify self_lb_en bit in modify_tir command. When this capability is set we can prevent TIRs from sending back loopback multicast traffic to their own RQs, by "refreshing TIRs" with modify_tir command, on every time new channels (SQs/RQs) are created at device open. This is needed since TIRs are static and only allocated once on driver load, and the loopback decision is under their responsibility. Fixes issues of the kind: "IPv6: eth2: IPv6 duplicate address fe80::e61d:2dff:fe5c:f2e9 detected!" The issue is seen since the IPv6 solicitations multicast messages are loopedback and the network stack thinks they are coming from another host.

now sctp auth cannot work well when setting a hmacid manually, which is caused by that we didn't use the network order for hmacid, so fix it by adding the transformation in sctp_auth_ep_set_hmacs. even we set hmacid with the network order in userspace, it still can't work, because of this condition in sctp_auth_ep_set_hmacs(): if (id > SCTP_AUTH_HMAC_ID_MAX) return -EOPNOTSUPP; so this wasn't working before and thus it won't break compatibility.

Daniel Borkmann authored
Since it's introduction in commit 69e3c75f ("net: TX_RING and packet mmap"), TX_RING could be used from SOCK_DGRAM and SOCK_RAW side. When used with SOCK_DGRAM only, the size_max > dev->mtu + reserve check should have reserve as 0, but currently, this is unconditionally set (in it's original form as dev->hard_header_len). I think this is not correct since tpacket_fill_skb() would then take dev->mtu and dev->hard_header_len into account for SOCK_DGRAM, the extra VLAN_HLEN could be possible in both cases. Presumably, the reserve code was copied from packet_snd(), but later on missed the check. Make it similar as we have it in packet_snd().
