With CONFIG_DMA_API_DEBUG enabled we get DMA unmapping warning in various places of the mvneta driver, for example when putting down an interface while traffic is passing through. The issue is when using s/w buffer management, the Rx buffers are mapped using dma_map_page but unmapped with dma_unmap_single. This patch fixes this by using the right unmapping function.

Summary: This appears to be necessary and sufficient change to enable `MPLS` on `ip6gre` tunnels (RFC4023). This diff allows IP6GRE devices to be recognized by MPLS kernel module and hence user can configure interface to accept packets with mpls headers as well setup mpls routes on them. Test Plan: Test plan consists of multiple containers connected via GRE-V6 tunnel. Then carrying out testing steps as below. - Carry out necessary sysctl settings on all containers ``` sysctl -w net.mpls.platform_labels=65536 sysctl -w net.mpls.ip_ttl_propagate=1 sysctl -w net.mpls.conf.lo.input=1 ``` - Establish IP6GRE tunnels ``` ip -6 tunnel add name if_1_2_1 mode ip6gre \ local 2401:db00:21:6048:feed:0::1 \ remote 2401:db00:21:6048:feed:0::2 key 1 ip link set dev if_1_2_1 up sysctl -w net.mpls.conf.if_1_2_1.input=1 ip -4 addr add 169.254.0.2/31 dev if_1_2_1 scope link ip -6 tunnel add name if_1_3_1 mode ip6gre \ local 2401:db00:21:6048:feed:0::1 \ remote 2401:db00:21:6048:feed:0::3 key 1 ip link set dev if_1_3_1 up sysctl -w net.mpls.conf.if_1_3_1.input=1 ip -4 addr add 169.254.0.4/31 dev if_1_3_1 scope link ``` - Install MPLS encap rules on node-1 towards node-2 ``` ip route add 192.168.0.11/32 nexthop encap mpls 32/64 \ via inet 169.254.0.3 dev if_1_2_1 ``` - Install MPLS forwarding rules on node-2 and node-3 ``` // node2 ip -f mpls route add 32 via inet 169.254.0.7 dev if_2_4_1 // node3 ip -f mpls route add 64 via inet 169.254.0.12 dev if_4_3_1 ``` - Ping 192.168.0.11 (node4) from 192.168.0.1 (node1) (where routing towards 192.168.0.1 is via IP route directly towards node1 from node4) ``` ping 192.168.0.11 ``` - tcpdump on interface to capture ping packets wrapped within MPLS header which inturn wrapped within IP6GRE header ``` 16:43:41.121073 IP6 2401:db00:21:6048:feed::1 > 2401:db00:21:6048:feed::2: DSTOPT GREv0, key=0x1, length 100: MPLS (label 32, exp 0, ttl 255) (label 64, exp 0, [S], ttl 255) IP 192.168.0.1 > 192.168.0.11: ICMP echo request, id 1208, seq 45, length 64 0x0000: 6000 2cdb 006c 3c3f 2401 db00 0021 6048 `.,..l<?$....!`H 0x0010: feed 0000 0000 0001 2401 db00 0021 6048 ........$....!`H 0x0020: feed 0000 0000 0002 2f00 0401 0401 0100 ......../....... 0x0030: 2000 8847 0000 0001 0002 00ff 0004 01ff ...G............ 0x0040: 4500 0054 3280 4000 ff01 c7cb c0a8 0001 E..T2.@......... 0x0050: c0a8 000b 0800 a8d7 04b8 002d 2d3c a05b ...........--<.[ 0x0060: 0000 0000 bcd8 0100 0000 0000 1011 1213 ................ 0x0070: 1415 1617 1819 1a1b 1c1d 1e1f 2021 2223 .............!"# 0x0080: 2425 2627 2829 2a2b 2c2d 2e2f 3031 3233 $%&'()*+,-./0123 0x0090: 3435 3637 4567 ``` Signed-off-by: NSaif Hasan <has@fb.com> Signed-off-by: NDavid S.

This patch fixes skb_shared area, which will be corrupted upon reception of 4K jumbo packets. Originally build_skb usage purpose was to reuse page for skb to eliminate needs of extra fragments. But that logic does not take into account that skb_shared_info should be reserved at the end of skb data area. In case packet data consumes all the page (4K), skb_shinfo location overflows the page. As a consequence, __build_skb zeroed shinfo data above the allocated page, corrupting next page. The issue is rarely seen in real life because jumbo are normally larger than 4K and that causes another code path to trigger. But it 100% reproducible with simple scapy packet, like: sendp(IP(dst="192.168.100.3") / TCP(dport=443) \ / Raw(RandString(size=(4096-40))), iface="enp1s0") Fixes: 018423e9 ("net: ethernet: aquantia: Add ring support code") Reported-by: NFriedemann Gerold <f.gerold@b-c-s.de> Reported-by: NMichael Rauch <michael@rauch.be> Signed-off-by: NFriedemann Gerold <f.gerold@b-c-s.de> Tested-by: NNikita Danilov <nikita.danilov@aquantia.com> Signed-off-by: NIgor Russkikh <igor.russkikh@aquantia.com> Signed-off-by: NDavid S.

Eric Dumazet says: ==================== netpoll: avoid capture effects for NAPI drivers As diagnosed by Song Liu, ndo_poll_controller() can be very dangerous on loaded hosts, since the cpu calling ndo_poll_controller() might steal all NAPI contexts (for all RX/TX queues of the NIC). This capture, showing one ksoftirqd eating all cycles can last for unlimited amount of time, since one cpu is generally not able to drain all the queues under load. It seems that all networking drivers that do use NAPI for their TX completions, should not provide a ndo_poll_controller() : Most NAPI drivers have netpoll support already handled in core networking stack, since netpoll_poll_dev() uses poll_napi(dev) to iterate through registered NAPI contexts for a device.

The rework of the kvmclock memory allocation during early boot results in encrypted storage, which is not shareable with the hypervisor. Create a new section for this data which is mapped unencrypted and take care that the later allocations for shared kvmclock memory is unencrypted as well. - Fix the build regression in the paravirt code introduced by the recent spectre v2 updates. - Ensure that the initial static page tables cover the fixmap space correctly so early console always works. This worked so far by chance, but recent modifications to the fixmap layout can - depending on kernel configuration - move the relevant entries to a different place which is not covered by the initial static page tables. - Address the regressions and issues which got introduced with the recent extensions to the Intel Recource Director Technology code. - Update maintainer entries to document reality" * 'x86-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/mm: Expand static page table for fixmap space MAINTAINERS: Add X86 MM entry x86/intel_rdt: Add Reinette as co-maintainer for RDT MAINTAINERS: Add Borislav to the x86 maintainers x86/paravirt: Fix some warning messages x86/intel_rdt: Fix incorrect loop end condition x86/intel_rdt: Fix exclusive mode handling of MBA resource x86/intel_rdt: Fix incorrect loop end condition x86/intel_rdt: Do not allow pseudo-locking of MBA resource x86/intel_rdt: Fix unchecked MSR access x86/intel_rdt: Fix invalid mode warning when multiple resources are managed x86/intel_rdt: Global closid helper to support future fixes x86/intel_rdt: Fix size reporting of MBA resource x86/intel_rdt: Fix data type in parsing callbacks x86/kvm: Use __bss_decrypted attribute in shared variables x86/mm: Add .bss..decrypted section to hold shared variables

Klaus Kusche reported that the I/O busy time in /proc/diskstats was not updating properly on 4.18. This is because we started using ktime to track elapsed time, and we convert nanoseconds to jiffies when we update the partition counter. However, this gets rounded down, so any I/Os that take less than a jiffy are not accounted for. Previously in this case, the value of jiffies would sometimes increment while we were doing I/O, so at least some I/Os were accounted for. Let's convert the stats to use nanoseconds internally. We still report milliseconds as before, now more accurately than ever. The value is still truncated to 32 bits for backwards compatibility.

Smatch reports that devlink_dpipe_send_and_alloc_skb() frees the skb on error so this is a double free.
