lan78xx: Resolve issue with changing MAC address

2019-01-13T08:51:02+00:00

[ Upstream commit 15515aaaa69659c502003926a2067ee76176148a ] Current state for the lan78xx driver does not allow for changing the MAC address of the interface, without either removing the module (if you compiled it that way) or rebooting the machine. If you attempt to change the MAC address, ifconfig will show the new address, however, the system/interface will not respond to any traffic using that configuration. A few short-term options to work around this are to unload the module and reload it with the new MAC address, change the interface to "promisc", or reboot with the correct configuration to change the MAC. This patch enables the ability to change the MAC address via fairly normal means... ifdown modify entry in /etc/network/interfaces OR a similar method ifup Then test via any network communication, such as ICMP requests to gateway. My only test platform for this patch has been a raspberry pi model 3b+. Signed-off-by: Jason Martinsen ----- Signed-off-by: David S. Miller Signed-off-by: Sasha Levin

USB: hso: Fix OOB memory access in hso_probe/hso_get_config_data

2018-12-29T12:37:54+00:00

commit 5146f95df782b0ac61abde36567e718692725c89 upstream. The function hso_probe reads if_num from the USB device (as an u8) and uses it without a length check to index an array, resulting in an OOB memory read in hso_probe or hso_get_config_data. Add a length check for both locations and updated hso_probe to bail on error. This issue has been assigned CVE-2018-19985.

usbnet: ipheth: fix potential recvmsg bug and recvmsg bug 2

2018-12-05T18:31:59+00:00

[ Upstream commit 45611c61dd503454b2edae00aabe1e429ec49ebe ] The bug is not easily reproducable, as it may occur very infrequently (we had machines with 20minutes heavy downloading before it occurred) However, on a virual machine (VMWare on Windows 10 host) it occurred pretty frequently (1-2 seconds after a speedtest was started) dev->tx_skb mab be freed via dev_kfree_skb_irq on a callback before it is set.

Before, usb_submit_urb was called and _after_ that, the skb was attached (dev->tx_skb). So, on a callback it was possible, however unlikely that the skb was freed before it was set. That way (because dev->tx_skb was not set to NULL after it was freed), it could happen that a skb from a earlier transmission was freed a second time (and the skb we should have freed did not get freed at all) Now we free the skb directly in ipheth_tx(). It is not passed to the callback anymore, eliminating the posibility of a double free of the same skb. Depending on the retval of usb_submit_urb() we use dev_kfree_skb_any() respectively dev_consume_skb_any() to free the skb.
