ipvlan:Fix out-of-bounds caused by unclear skb->cb

2023-05-30T11:38:34+00:00

[ Upstream commit 90cbed5247439a966b645b34eb0a2e037836ea8e ]

If skb enqueue the qdisc, fq_skb_cb(skb)->time_to_send is changed which
is actually skb->cb, and IPCB(skb_in)->opt will be used in
__ip_options_echo. It is possible that memcpy is out of bounds and lead
to stack overflow.
We should clear skb->cb before ip_local_out or ip6_local_out.

v2:
1. clean the stack info
2. use IPCB/IP6CB instead of skb->cb

crash on stable-5.10(reproduce in kasan kernel).

ipvlan: Fix out-of-bound bugs caused by unset skb->mac_header

2022-09-28T08:56:51+00:00

[ Upstream commit 81225b2ea161af48e093f58e8dfee6d705b16af4 ]

If an AF_PACKET socket is used to send packets through ipvlan and the
default xmit function of the AF_PACKET socket is changed from
dev_queue_xmit() to packet_direct_xmit() via setsockopt() with the option
name of PACKET_QDISC_BYPASS, the skb->mac_header may not be reset and
remains as the initial value of 65535, this may trigger slab-out-of-bounds
bugs as following:

The root cause is:
  1. packet_snd() only reset skb->mac_header when sock->type is SOCK_RAW
     and skb->protocol is not specified as in packet_parse_headers()

  2. packet_direct_xmit() doesn't reset skb->mac_header as dev_queue_xmit()

In this case, skb->mac_header is 65535 when ipvlan_xmit_mode_l2() is
called. So when ipvlan_xmit_mode_l2() gets mac header with eth_hdr() which
use "skb->head + skb->mac_header", out-of-bound access occurs.

This patch replaces eth_hdr() with skb_eth_hdr() in ipvlan_xmit_mode_l2()
and reset mac header in multicast to solve this out-of-bound bug.

ipvlan: do not add hardware address of master to its unicast filter list

2020-03-20T09:54:14+00:00

[ Upstream commit 63aae7b17344d4b08a7d05cb07044de4c0f9dcc6 ]

There is a problem when ipvlan slaves are created on a master device that
is a vmxnet3 device (ipvlan in VMware guests). The vmxnet3 driver does not
support unicast address filtering. When an ipvlan device is brought up in
ipvlan_open(), the ipvlan driver calls dev_uc_add() to add the hardware
address of the vmxnet3 master device to the unicast address list of the
master device, phy_dev->uc. This inevitably leads to the vmxnet3 master
device being forced into promiscuous mode by __dev_set_rx_mode().

Promiscuous mode is switched on the master despite the fact that there is
still only one hardware address that the master device should use for
filtering in order for the ipvlan device to be able to receive packets.
The comment above struct net_device describes the uc_promisc member as a
"counter, that indicates, that promiscuous mode has been enabled due to
the need to listen to additional unicast addresses in a device that does
not implement ndo_set_rx_mode()". Moreover, the design of ipvlan
guarantees that only the hardware address of a master device,
phy_dev->dev_addr, will be used to transmit and receive all packets from
its ipvlan slaves. Thus, the unicast address list of the master device
should not be modified by ipvlan_open() and ipvlan_stop() in order to make
ipvlan a workable option on masters that do not support unicast address
filtering.

net: ipvlan: Fix ipvlan device tso disabled while NETIF_F_IP_CSUM is set

2019-06-25T03:36:53+00:00

[ Upstream commit ceae266bf0ae6564ac16d086bf749a096fa90ded ]

There's some NICs, such as hinic, with NETIF_F_IP_CSUM and NETIF_F_TSO
on but NETIF_F_HW_CSUM off. And ipvlan device features will be
NETIF_F_TSO on with NETIF_F_IP_CSUM and NETIF_F_IP_CSUM both off as
IPVLAN_FEATURES only care about NETIF_F_HW_CSUM. So TSO will be
disabled in netdev_fix_features.
For example:
Features for enp129s0f0:
rx-checksumming: on
tx-checksumming: on
        tx-checksum-ipv4: on
        tx-checksum-ip-generic: off [fixed]
        tx-checksum-ipv6: on
