tool codeexpert failed: error: (RECITATION)
args: map[Question:In `netlink_recvmsg`, `scm.creds` is initialized from `NETLINK_CREDS(skb)`.
Is there any path where `skb` is allocated inside the kernel (e.g. by `nlmsg_new` or `alloc_skb`), and `skb->cb` is zeroed, but then `skb->cb` is overwritten by something else, and then passed to `netlink_recvmsg`?
Or maybe `skb` is cloned, and `skb->cb` is not copied correctly?
Or maybe `netlink_recvmsg` is receiving an `skb` that was NOT allocated for netlink, but for some other protocol, and then injected into a netlink socket?
Wait, `udevd` is receiving a netlink message. `udevd` listens on netlink sockets (kobject uevent).
Kobject uevents are generated by the kernel.
Let's check how kobject uevents are generated and sent.
Look at `lib/kobject_uevent.c`.] |
