net: core: Convert dev_set_mac_address() to struct sockaddr_storage

2025-05-27T06:25:43+00:00

All users of dev_set_mac_address() are now using a struct sockaddr_storage. Convert the internal data type to struct sockaddr_storage, drop the casts, and update pointer types. Acked-by: Gustavo A.

ieee802154: Use struct sockaddr_storage with dev_set_mac_address()

2025-05-27T06:25:43+00:00

Switch to struct sockaddr_storage for calling dev_set_mac_address(). Add a temporary cast to struct sockaddr, which will be removed in a subsequent patch. Acked-by: Gustavo A. R.

inet: frags: save a pair of atomic operations in reassembly

2025-03-18T12:18:36+00:00

As mentioned in commit 648700f76b03 ("inet: frags: use rhashtables for reassembly units"): A followup patch will even remove the refcount hold/release left from prior implementation and save a couple of atomic operations. This patch implements this idea, seven years later.

inet: frags: change inet_frag_kill() to defer refcount updates

2025-03-18T12:18:36+00:00

In the following patch, we no longer assume inet_frag_kill() callers own a reference. Consuming two refcounts from inet_frag_kill() would lead in UAF. Propagate the pointer to the refs that will be consumed later by the final inet_frag_putn() call.

net: move misc netdev_lock flavors to a separate header

2025-03-08T17:06:50+00:00

Move the more esoteric helpers for netdev instance lock to a dedicated header. This avoids growing netdevice.h to infinity and makes rebuilding the kernel much faster (after touching the header with the helpers). The main netdev_lock() / netdev_unlock() functions are used in static inlines in netdevice.h and will probably be used most commonly, so keep them in netdevice.h.

net: rename netns_local to netns_immutable

2025-03-04T11:44:48+00:00

The name 'netns_local' is confusing. A following commit will export it via netlink, so let's use a more explicit name. Reported-by: Eric Dumazet Suggested-by: Kuniyuki Iwashima Signed-off-by: Nicolas Dichtel Reviewed-by: Kuniyuki Iwashima Signed-off-by: Paolo Abeni

ieee802154: 6lowpan: Validate link netns in newlink() of rtnl_link_ops

2025-02-21T23:28:02+00:00

Device denoted by IFLA_LINK is in link_net (IFLA_LINK_NETNSID) or source netns by design, but 6lowpan uses dev_net. Note dev->netns_local is set to true and currently link_net is implemented via a netns change. These together effectively reject IFLA_LINK_NETNSID. This patch adds a validation to ensure link_net is either NULL or identical to dev_net. Thus it would be fine to continue using dev_net when rtnetlink core begins to create devices directly in target netns.

rtnetlink: Pack newlink() params into struct

2025-02-21T23:28:02+00:00

There are 4 net namespaces involved when creating links: - source netns - where the netlink socket resides, - target netns - where to put the device being created, - link netns - netns associated with the device (backend), - peer netns - netns of peer device. Currently, two nets are passed to newlink() callback - "src_net" parameter and "dev_net" (implicitly in net_device). They are set as follows, depending on netlink attributes in the request. +------------+-------------------+---------+---------+ | peer netns | IFLA_LINK_NETNSID | src_net | dev_net | +------------+-------------------+---------+---------+ | | absent | source | target | | absent +-------------------+---------+---------+ | | present | link | link | +------------+-------------------+---------+---------+ | | absent | peer | target | | present +-------------------+---------+---------+ | | present | peer | link | +------------+-------------------+---------+---------+ When IFLA_LINK_NETNSID is present, the device is created in link netns first and then moved to target netns. This has some side effects, including extra ifindex allocation, ifname validation and link events. These could be avoided if we create it in target netns from the beginning. On the other hand, the meaning of src_net parameter is ambiguous. It varies depending on how parameters are passed. It is the effective link (or peer netns) by design, but some drivers ignore it and use dev_net instead. To provide more netns context for drivers, this patch packs existing newlink() parameters, along with the source netns, link netns and peer netns, into a struct. The old "src_net" is renamed to "net" to avoid confusion with real source netns, and will be deprecated later. The use of src_net are converted to params->net trivially.
