The negotiation of flow control / pause frame modes was broken since commit fcf1f59a ("net: phy: marvell: rearrange to use genphy_read_lpa()") moved the setting of phydev->duplex below the phy_resolve_aneg_pause call. Due to a check of DUPLEX_FULL in that function, phydev->pause was no longer set. Fix it by moving the parsing of the status variable before the blocks dealing with the pause frames. As the Marvell 88E1510 datasheet does not specify the timing between the link status and the "Speed and Duplex Resolved" bit, we have to force the link down as long as the resolved bit is not set, to avoid reporting link up before we even have valid Speed/Duplex. Tested with a Marvell 88E1510 (RGMII to Copper/1000Base-T) Fixes: fcf1f59a ("net: phy: marvell: rearrange to use genphy_read_lpa()") Signed-off-by:

In rds_free_mr(), it calls rds_destroy_mr(mr) directly. But this defeats the purpose of reference counting and makes MR free handling impossible. It means that holding a reference does not guarantee that it is safe to access some fields. For example, In rds_cmsg_rdma_dest(), it increases the ref count, unlocks and then calls mr->r_trans->sync_mr(). But if rds_free_mr() (and rds_destroy_mr()) is called in between (there is no lock preventing this to happen), r_trans_private is set to NULL, causing a panic. Similar issue is in rds_rdma_unuse().

The current arm BPF JIT does not correctly compile RSH or ARSH when the immediate shift amount is 0. This causes the "rsh64 by 0 imm" and "arsh64 by 0 imm" BPF selftests to hang the kernel by reaching an instruction the verifier determines to be unreachable. The root cause is in how immediate right shifts are encoded on arm. For LSR and ASR (logical and arithmetic right shift), a bit-pattern of 00000 in the immediate encodes a shift amount of 32. When the BPF immediate is 0, the generated code shifts by 32 instead of the expected behavior (a no-op). This patch fixes the bugs by adding an additional check if the BPF immediate is 0. After the change, the above mentioned BPF selftests pass. Fixes: 39c13c20 ("arm: eBPF JIT compiler") Co-developed-by:

Fixes CT entries list corruption. After allowing parallel insertion/removals in upper nf flow table layer, unprotected ct entries list can be corrupted by parallel add/del on the same flow table. CT entries list is only used while freeing a ct zone flow table to go over all the ct entries offloaded on that zone/table, and flush the table. As rhashtable already provides an api to go over all the inserted entries, fix the race by using the rhashtable iteration instead, and remove the list.

Creation and management of L2TPv3 tunnels and session through netlink requires CAP_NET_ADMIN. However, a process with CAP_NET_ADMIN in a non-initial user namespace gets an EPERM due to the use of the genetlink GENL_ADMIN_PERM flag. Thus, management of L2TP VPNs inside an unprivileged container won't work. We replaced the GENL_ADMIN_PERM by the GENL_UNS_ADMIN_PERM flag similar to other network modules which also had this problem, e.g., openvswitch (commit 4a92602a "openvswitch: allow management from inside user namespaces") and nl80211 (commit 5617c6cd "nl80211: Allow privileged operations from user namespaces"). I tested this in the container runtime trustm3 (trustm3.github.io) and was able to create l2tp tunnels and sessions in unpriviliged (user namespaced) containers using a private network namespace. For other runtimes such as docker or lxc this should work, too. Signed-off-by:

The behaviour for what is considered an anycast address changed in commit 45e4fd26 ("ipv6: Only create RTF_CACHE routes after encountering pmtu exception"). This now considers the first address in a subnet where there is a route via a gateway to be an anycast address. This breaks path MTU discovery and traceroutes when a host in a remote network uses the address at the start of a prefix (eg 2600:: advertised as 2600::/48 in the DFZ) as ICMP errors will not be sent to anycast addresses. This patch excludes any routes with a gateway, or via point to point links, like the behaviour previously from rt6_is_gw_or_nonexthop in net/ipv6/route.c. This can be tested with: ip link add v1 type veth peer name v2 ip netns add test ip netns exec test ip link set lo up ip link set v2 netns test ip link set v1 up ip netns exec test ip link set v2 up ip addr add 2001:db8::1/64 dev v1 nodad ip addr add 2001:db8:100:: dev lo nodad ip netns exec test ip addr add 2001:db8::2/64 dev v2 nodad ip netns exec test ip route add unreachable 2001:db8:1::1 ip netns exec test ip route add 2001:db8:100::/64 via 2001:db8::1 ip netns exec test sysctl net.ipv6.conf.all.forwarding=1 ip route add 2001:db8:1::1 via 2001:db8::2 ping -I 2001:db8::1 2001:db8:1::1 -c1 ping -I 2001:db8:100:: 2001:db8:1::1 -c1 ip addr delete 2001:db8:100:: dev lo ip netns delete test Currently the first ping will get back a destination unreachable ICMP error, but the second will never get a response, with "icmp6_send: acast source" logged.

Since commit fac6fce9 ("net: icmp6: provide input address for traceroute6") ICMPv6 errors have source addresses from the ingress interface. However, this overrides when source address selection is influenced by setting preferred source addresses on routes. This can result in ICMP errors being lost to upstream BCP38 filters when the wrong source addresses are used, breaking path MTU discovery and traceroute. This patch sets the modified source address selection to only take place when the route used has no prefsrc set. It can be tested with: ip link add v1 type veth peer name v2 ip netns add test ip netns exec test ip link set lo up ip link set v2 netns test ip link set v1 up ip netns exec test ip link set v2 up ip addr add 2001:db8::1/64 dev v1 nodad ip addr add 2001:db8::3 dev v1 nodad ip netns exec test ip addr add 2001:db8::2/64 dev v2 nodad ip netns exec test ip route add unreachable 2001:db8:1::1 ip netns exec test ip addr add 2001:db8:100::1 dev lo ip netns exec test ip route add 2001:db8::1 dev v2 src 2001:db8:100::1 ip route add 2001:db8:1000::1 via 2001:db8::2 traceroute6 -s 2001:db8::1 2001:db8:1000::1 traceroute6 -s 2001:db8::3 2001:db8:1000::1 ip netns delete test Output before: $ traceroute6 -s 2001:db8::1 2001:db8:1000::1 traceroute to 2001:db8:1000::1 (2001:db8:1000::1), 30 hops max, 80 byte packets 1 2001:db8::2 (2001:db8::2) 0.843 ms !N 0.396 ms !N 0.257 ms !N $ traceroute6 -s 2001:db8::3 2001:db8:1000::1 traceroute to 2001:db8:1000::1 (2001:db8:1000::1), 30 hops max, 80 byte packets 1 2001:db8::2 (2001:db8::2) 0.772 ms !N 0.257 ms !N 0.357 ms !N After: $ traceroute6 -s 2001:db8::1 2001:db8:1000::1 traceroute to 2001:db8:1000::1 (2001:db8:1000::1), 30 hops max, 80 byte packets 1 2001:db8:100::1 (2001:db8:100::1) 8.885 ms !N 0.310 ms !N 0.174 ms !N $ traceroute6 -s 2001:db8::3 2001:db8:1000::1 traceroute to 2001:db8:1000::1 (2001:db8:1000::1), 30 hops max, 80 byte packets 1 2001:db8::2 (2001:db8::2) 1.403 ms !N 0.205 ms !N 0.313 ms !N Fixes: fac6fce9 ("net: icmp6: provide input address for traceroute6") Signed-off-by:

Martin Fuzzey says: ==================== Fix Wake on lan with FEC on i.MX6 This series fixes WoL support with the FEC on i.MX6 The support was already in mainline but seems to have bitrotted somewhat. Only tested with i.MX6DL Changes V2->V3 Patch 1: fix non initialized variable introduced in V2 causing probe to sometimes fail. Patch 2: remove /delete-property/interrupts-extended in arch/arm/boot/dts/imx6qp.dtsi. Patches 3 and 4: Add received Acked-by and RB tags. Changes V1->V2 Move the register offset and bit number from the DT to driver code Add SOB from Fugang Duan for the NXP code on which this is based ==================== Signed-off-by: -
