Title
llc: make llc_ui_sendmsg() more robust against bonding changes
Summary
In the Linux kernel, the following vulnerability has been resolved: llc: make llc_ui_sendmsg() more robust against bonding changes syzbot was able to trick llc_ui_sendmsg(), allocating an skb with no headroom, but subsequently trying to push 14 bytes of Ethernet header [1] Like some others, llc_ui_sendmsg() releases the socket lock before calling sock_alloc_send_skb(). Then it acquires it again, but does not redo all the sanity checks that were performed. This fix: - Uses LL_RESERVED_SPACE() to reserve space. - Check all conditions again after socket lock is held again. - Do not account Ethernet header for mtu limitation.

llc_ui_sendmsg() releases the socket lock before\\ncalling sock_alloc_send_skb().\\nThen it acquires it again, but does not redo all the sanity checks\\nthat were performed.\\n\\nThis fix:\\n\\n- Uses LL_RESERVED_SPACE() to reserve space.\\n- Check all conditions again after socket lock is held again.\\n- Do not account Ethernet header for mtu limitation.\\n\\n[1]\\n\\nskbuff: skb_under_panic:
