2025-06-03selftest/net/ovpn: fix TCP socket creationAntonio Quartulli
TCP sockets cannot be created with AF_UNSPEC, but one among the supported family must be used. Since commit 944f8b6abab6 ("selftest/net/ovpn: extend coverage with more test cases") the default address family for all tests was changed from AF_INET to AF_UNSPEC, thus breaking all TCP cases. Restore AF_INET as default address family for TCP listeners. Fixes: 944f8b6abab6 ("selftest/net/ovpn: extend coverage with more test cases") Signed-off-by: Antonio Quartulli <antonio@openvpn.net>
2025-06-03ovpn: avoid sleep in atomic context in TCP RX error pathAntonio Quartulli
Upon error along the TCP data_ready event path, we have the following chain of calls: strp_data_ready() ovpn_tcp_rcv() ovpn_peer_del() ovpn_socket_release() Since strp_data_ready() may be invoked from softirq context, and ovpn_socket_release() may sleep, the above sequence may cause a sleep in atomic context like the following: BUG: sleeping function called from invalid context at ./ovpn-backports-ovpn-net-next-main-6.15.0-rc5-20250522/drivers/net/ovpn/socket.c:71 in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 25, name: ksoftirqd/3 5 locks held by ksoftirqd/3/25: #0: ffffffe000cd0580 (rcu_read_lock){....}-{1:2}, at: netif_receive_skb+0xb8/0x5b0 OpenVPN/ovpn-backports#1: ffffffe000cd0580 (rcu_read_lock){....}-{1:2}, at: netif_receive_skb+0xb8/0x5b0 OpenVPN/ovpn-backports#2: ffffffe000cd0580 (rcu_read_lock){....}-{1:2}, at: ip_local_deliver_finish+0x66/0x1e0 OpenVPN/ovpn-backports#3: ffffffe003ce9818 (slock-AF_INET/1){+.-.}-{2:2}, at: tcp_v4_rcv+0x156e/0x17a0 OpenVPN/ovpn-backports#4: ffffffe000cd0580 (rcu_read_lock){....}-{1:2}, at: ovpn_tcp_data_ready+0x0/0x1b0 [ovpn] CPU: 3 PID: 25 Comm: ksoftirqd/3 Not tainted 5.10.104+ #0 Call Trace: walk_stackframe+0x0/0x1d0 show_stack+0x2e/0x44 dump_stack+0xc2/0x102 ___might_sleep+0x29c/0x2b0 __might_sleep+0x62/0xa0 ovpn_socket_release+0x24/0x2d0 [ovpn] unlock_ovpn+0x6e/0x190 [ovpn] ovpn_peer_del+0x13c/0x390 [ovpn] ovpn_tcp_rcv+0x280/0x560 [ovpn] __strp_recv+0x262/0x940 strp_recv+0x66/0x80 tcp_read_sock+0x122/0x410 strp_data_ready+0x156/0x1f0 ovpn_tcp_data_ready+0x92/0x1b0 [ovpn] tcp_data_ready+0x6c/0x150 tcp_rcv_established+0xb36/0xc50 tcp_v4_do_rcv+0x25e/0x380 tcp_v4_rcv+0x166a/0x17a0 ip_protocol_deliver_rcu+0x8c/0x250 ip_local_deliver_finish+0xf8/0x1e0 ip_local_deliver+0xc2/0x2d0 ip_rcv+0x1f2/0x330 __netif_receive_skb+0xfc/0x290 netif_receive_skb+0x104/0x5b0 br_pass_frame_up+0x190/0x3f0 br_handle_frame_finish+0x3e2/0x7a0 br_handle_frame+0x750/0xab0 __netif_receive_skb_core.constprop.0+0x4c0/0x17f0 __netif_receive_skb+0xc6/0x290 netif_receive_skb+0x104/0x5b0 xgmac_dma_rx+0x962/0xb40 __napi_poll.constprop.0+0x5a/0x350 net_rx_action+0x1fe/0x4b0 __do_softirq+0x1f8/0x85c run_ksoftirqd+0x80/0xd0 smpboot_thread_fn+0x1f0/0x3e0 kthread+0x1e6/0x210 ret_from_kernel_thread+0x8/0xc Fix this issue by postponing the ovpn_peer_del() call to a scheduled worker, as we already do in ovpn_tcp_send_sock() for the very same reason.

Here synchronize_rcu() is invoked, after which ovpn_sock->sock->sk becomes NULL, due to the concurrent socket closing triggered from userspace. After having invoked synchronize_rcu(), ovpn_socket_release() will attempt dereferencing ovpn_sock->sock->sk, triggering the crash reported above. The reason for accessing sk is that we need to retrieve its protocol and continue the cleanup routine accordingly. This crash can be easily produced by running openvpn userspace in client mode with `--keepalive 10 20`, while entirely omitting this option on the server side. After 20 seconds ovpn will assume the peer (server) to be dead, will start removing it and will notify userspace. The latter will receive the notification and close the transport socket, thus triggering the crash. To fix the race condition for good, we need to refactor struct ovpn_socket. Since ovpn is always only interested in the sock->sk member (struct sock *) we can directly hold a reference to it, raher than accessing it via its struct socket container. This means changing "struct socket *ovpn_socket->sock" to "struct sock *ovpn_socket->sk". While acquiring a reference to sk, we can increase its refcounter without affecting the socket close()/destroy() notification (which we rely on when userspace closes a socket we are using). By increasing sk's refcounter we know we can dereference it in ovpn_socket_release() without incurring in any race condition anymore. ovpn_socket_release() will ultimately decrease the reference counter.

2025-06-03ovpn: properly deconfigure UDP-tunnelAntonio Quartulli
When deconfiguring a UDP-tunnel from a socket, we cannot call setup_udp_tunnel_sock() with an empty config, because this helper is expected to be invoked only during setup. Get rid of the call to setup_udp_tunnel_sock() and just revert what it did during socket initialization.. Note that the global udp_encap_needed_key and the GRO state are left untouched: udp_destroy_socket() will eventually take care of them.

2025-06-03vmxnet3: correctly report gso type for UDP tunnelsRonak Doshi
Commit 3d010c8031e3 ("udp: do not accept non-tunnel GSO skbs landing in a tunnel") added checks in linux stack to not accept non-tunnel GRO packets landing in a tunnel. This exposed an issue in vmxnet3 which was not correctly reporting GRO packets for tunnel packets. This patch fixes this issue by setting correct GSO type for the tunnel packets. Currently, vmxnet3 does not support reporting inner fields for LRO tunnel packets. The issue is not seen for egress drivers that do not use skb inner fields. The workaround is to enable tnl-segmentation offload on the egress interfaces if the driver supports it. This problem pre-exists this patch fix and can be addressed as a separate future patch.

2025-06-02PCI: j721e: Fix host/endpoint dependenciesArnd Bergmann
The j721e driver has a single platform driver that can be built-in or a loadable module, but it calls two separate backend drivers depending on whether it is a host or endpoint. If the two modes are not the same, we can end up with a situation where the built-in pci-j721e driver tries to call the modular host or endpoint driver, which causes a link failure: ld.lld-21: error: undefined symbol: cdns_pcie_ep_setup >>> referenced by pci-j721e.c >>> drivers/pci/controller/cadence/pci-j721e.o:(j721e_pcie_probe) in archive vmlinux.a ld.lld-21: error: undefined symbol: cdns_pcie_host_setup >>> referenced by pci-j721e.c >>> drivers/pci/controller/cadence/pci-j721e.o:(j721e_pcie_probe) in archive vmlinux.a Rework the dependencies so that the 'select' is done by the common Kconfig symbol, based on which of the two are enabled. Effectively this means that having one built-in makes the other either built-in or disabled, but all configurations will now build.

2025-06-02cifs: dns resolution is needed only for primary channelShyam Prasad N
When calling cifs_reconnect, before the connection to the server is reestablished, the code today does a DNS resolution and updates server->dstaddr. However, this is not necessary for secondary channels. Secondary channels use the interface list returned by the server to decide which address to connect to. And that happens after tcon is reconnected and server interfaces are requested.

When the server interface info changes (more common in clustered servers like Azure Files), the per-channel iface gets updated. However, this did not update the corresponding dstaddr. As a result these channels will still connect (or try connecting) to older addresses.

cifs_reconnect can be called with a flag to mark the session as needing reconnect too. When this is done, we expect the connections of all channels to be reconnected too, which is not happening today. Without doing this, we have seen bad things happen when primary and secondary channels are connected to different servers (in case of cloud services like Azure Files SMB). This change would force all connections to reconnect as well, not just the sessions and tcons.

This was a problem for runtime PM operations which might not have the "master" device available in all situation. The SPI NAND subsystem has seen the introduction of DTR operations (the equivalent of DDR transfers), which involved quite a few preparation patches for clarifying macro names. In the raw NAND subsystem, the brcmnand driver has been "fixed" for old legacy SoCs with an update of the ->exec_op() hook, there has been the introduction of a new controller driver named Loongson-1, and the Qualcomm driver has received quite a few misc fixes as well as a new compatible.
