2025-05-27vsock: Move lingering logic to af_vsock coreMichal Luczaj
Lingering should be transport-independent in the long run. In preparation for supporting other transports, as well as the linger on shutdown(), move code to core. Generalize by querying vsock_transport::unsent_bytes(), guard against the callback being unimplemented. Do not pass sk_lingertime explicitly. Pull SOCK_LINGER check into vsock_linger(). Flatten the function. Remove the nested block by inverting the condition: return early on !timeout.

2025-05-27vsock/virtio: Linger on unsent dataMichal Luczaj
Currently vsock's lingering effectively boils down to waiting (or timing out) until packets are consumed or dropped by the peer; be it by receiving the data, closing or shutting down the connection. To align with the semantics described in the SO_LINGER section of man socket(7) and to mimic AF_INET's behaviour more closely, change the logic of a lingering close(): instead of waiting for all data to be handled, block until data is considered sent from the vsock's transport point of view. That is until worker picks the packets for processing and decrements virtio_vsock_sock::bytes_unsent down to 0. Note that (some interpretation of) lingering was always limited to transports that called virtio_transport_wait_close() on transport release. This does not change, i.e. under Hyper-V and VMCI no lingering would be observed. The implementation does not adhere strictly to man page's interpretation of SO_LINGER: shutdown() will not trigger the lingering. This follows AF_INET.

Add support for the MaxLinear MxL86110 Gigabit Ethernet PHY, a low-power, cost-optimized transceiver supporting 10/100/1000 Mbps over twisted-pair copper, compliant with IEEE 802.3. The driver implements basic features such as: - Device initialization - RGMII interface timing configuration - Wake-on-LAN support - LED initialization and control via /sys/class/leds This driver has been tested on multiple Variscite boards, including: - VAR-SOM-MX93 (i.MX93) - VAR-SOM-MX8M-PLUS (i.MX8MP) Example boot log showing driver probe: [ 7.692101] imx-dwmac 428a0000.ethernet eth0: PHY [stmmac-0:00] driver [MXL86110 Gigabit Ethernet] (irq=POLL) Signed-off-by: Stefano Radaelli <stefano.radaelli21@gmail.com> Reviewed-by: Andrew Lunn <andrew@lunn.ch> Link: https://patch.msgid.link/20250521212821.593057-1-stefano.radaelli21@gmail.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2025-05-27wireguard: allowedips: add WGALLOWEDIP_F_REMOVE_ME flagJordan Rife
The current netlink API for WireGuard does not directly support removal of allowed ips from a peer. A user can remove an allowed ip from a peer in one of two ways: 1. By using the WGPEER_F_REPLACE_ALLOWEDIPS flag and providing a new list of allowed ips which omits the allowed ip that is to be removed. 2. By reassigning an allowed ip to a "dummy" peer then removing that peer with WGPEER_F_REMOVE_ME. With the first approach, the driver completely rebuilds the allowed ip list for a peer. If my current configuration is such that a peer has allowed ips 192.168.0.2 and 192.168.0.3 and I want to remove 192.168.0.2 the actual transition looks like this. [192.168.0.2, 192.168.0.3] <-- Initial state [] <-- Step 1: Allowed ips removed for peer [192.168.0.3] <-- Step 2: Allowed ips added back for peer This is true even if the allowed ip list is small and the update does not need to be batched into multiple WG_CMD_SET_DEVICE requests, as the removal and subsequent addition of ips is non-atomic within a single request. Consequently, wg_allowedips_lookup_dst and wg_allowedips_lookup_src may return NULL while reconfiguring a peer even for packets bound for ips a user did not intend to remove leading to unintended interruptions in connectivity. This presents in userspace as failed calls to sendto and sendmsg for UDP sockets. In my case, I ran netperf while repeatedly reconfiguring the allowed ips for a peer with wg. /usr/local/bin/netperf -H 10.102.73.72 -l 10m -t UDP_STREAM -- -R 1 -m 1024 send_data: data send error: No route to host (errno 113) netperf: send_omni: send_data failed: No route to host While this may not be of particular concern for environments where peers and allowed ips are mostly static, systems like Cilium manage peers and allowed ips in a dynamic environment where peers (i.e. Kubernetes nodes) and allowed ips (i.e. pods running on those nodes) can frequently change making WGPEER_F_REPLACE_ALLOWEDIPS problematic. The second approach avoids any possible connectivity interruptions but is hacky and less direct, requiring the creation of a temporary peer just to dispose of an allowed ip. Introduce a new flag called WGALLOWEDIP_F_REMOVE_ME which in the same way that WGPEER_F_REMOVE_ME allows a user to remove a single peer from a WireGuard device's configuration allows a user to remove an ip from a peer's set of allowed ips. This enables incremental updates to a device's configuration without any connectivity blips or messy workarounds. A corresponding patch for wg extends the existing `wg set` interface to leverage this feature. $ wg set wg0 peer <PUBKEY> allowed-ips +192.168.88.0/24,-192.168.0.1/32 When '+' or '-' is prepended to any ip in the list, wg clears WGPEER_F_REPLACE_ALLOWEDIPS and sets the WGALLOWEDIP_F_REMOVE_ME flag on any ip prefixed with '-'.

Kees Cook says: ==================== net: Convert dev_set_mac_address() to struct sockaddr_storage As part of the effort to allow the compiler to reason about object sizes, we need to deal with the problematic variably sized struct sockaddr, which has no internal runtime size tracking.

Specifically: - inet_addr_is_any() - netif_set_mac_address() - dev_set_mac_address() - dev_set_mac_address_user() Only a few callers of dev_set_mac_address() needed adjustment; all others were already using struct sockaddr_storage internally. v1: https://lore.kernel.org/all/20250520222452.work.063-kees@kernel.org/ ==================== Link: https://patch.msgid.link/20250521204310.it.500-kees@kernel.org Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2025-05-27rtnetlink: do_setlink: Use struct sockaddr_storageKees Cook
Instead of a heap allocating a variably sized struct sockaddr and lying about the type in the call to netif_set_mac_address(), use a stack allocated struct sockaddr_storage. This lets us drop the cast and avoid the allocation. Putting "ss" on the stack means it will get a reused stack slot since it is the same size (128B) as other existing single-scope stack variables, like the vfinfo array (128B), so no additional stack space is used by this function.

2025-05-26Don't propagate mounts into detached treesAl Viro
All versions up to 6.14 did not propagate mount events into detached tree. Shortly after 6.14 a merge of vfs-6.15-rc1.mount.namespace (130e696aa68b) has changed that. Unfortunately, that has caused userland regressions (reported in https://lore.kernel.org/all/CAOYeF9WQhFDe+BGW=Dp5fK8oRy5AgZ6zokVyTj1Wp4EUiYgt4w@mail.gmail.com/) Straight revert wouldn't be an option - in particular, the variant in 6.14 had a bug that got fixed in d1ddc6f1d9f0 ("fix IS_MNT_PROPAGATING uses") and we don't want to bring the bug back. This is a modification of manual revert posted by Christian, with changes needed to avoid reintroducing the breakage in scenario described in d1ddc6f1d9f0.
