Fix the DATA packet transmission to disable nofrag for UDPv4 on an AF_INET6 socket as well as UDPv6 when trying to transmit fragmentably. Without this, packets filled to the normal size used by the kernel AFS client of 1412 bytes be rejected by udp_sendmsg() with EMSGSIZE immediately. The ->sk_error_report() notification hook is called, but rxrpc doesn't generate a trace for it. This is a temporary fix; a more permanent solution needs to involve changing the size of the packets being filled in accordance with the MTU, which isn't currently done in AF_RXRPC. The reason for not doing so was that, barring the last packet in an rx jumbo packet, jumbos can only be assembled out of 1412-byte packets - and the plan was to construct jumbos on the fly at transmission time. Also, there's no point turning on IPV6_MTU_DISCOVER, since IPv6 has to engage in this anyway since fragmentation is only done by the sender. We can then condense the switch-statement in rxrpc_send_data_packet(). Fixes: 75b54cb5 ("rxrpc: Add IPv6 support") Signed-off-by: David Howells <dhowells@redhat.com> Signed-off-by: David S.

Clemens Gruber authored
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.

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 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.

Building with some experimental patches, I came across a warning in the tls code: include/linux/compiler.h:215:30: warning: assignment discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers] 215 | *(volatile typeof(x) *)&(x) = (val); \ | ^ net/tls/tls_main.c:650:4: note: in expansion of macro 'smp_store_release' 650 | smp_store_release(&saved_tcpv4_prot, prot); This appears to be a legitimate warning about assigning a const pointer into the non-const 'saved_tcpv4_prot' global. Annotate both the ipv4 and ipv6 pointers 'const' to make the code internally consistent.

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: Michael Weiß <michael.weiss@aisec.fraunhofer.de> Signed-off-by: David S. Miller <davem@davemloft.net>

Shannon Nelson says: ==================== ionic: fw upgrade filter fixes With further testing of the fw-upgrade operations we found a couple of issues that needed to be cleaned up: - the filters other than the base MAC address need to be reinstated into the device - we don't need to remove the station MAC filter if it isn't changing from a previous MAC filter ==================== Signed-off-by: David S.

The code was working too hard and in some cases was trying to delete filters that weren't there, generating a potentially misleading error message.

The NIC's filters are lost in the midst of the fw-upgrade so we need to replay them into the FW. We also remove the unused ionic_rx_filter_del() function.
