[PATCH 5.4] usb: gadget: u_ether: fix regression in setting fixed MAC address

by Marian Postevca

commit b337af3a4d6147000b7ca6b3438bf5c820849b37 upstream. In systemd systems setting a fixed MAC address through the "dev_addr" module argument fails systematically. When checking the MAC address after the interface is created it always has the same but different MAC address to the one supplied as argument. This is partially caused by systemd which by default will set an internally generated permanent MAC address for interfaces that are marked as having a randomly generated address. Commit 890d5b40908bfd1a ("usb: gadget: u_ether: fix race in setting MAC address in setup phase") didn't take into account the fact that the interface must be marked as having a set MAC address when it's set as module argument. Fixed by marking the interface with NET_ADDR_SET when the "dev_addr" module argument is supplied. Reported-by: Maximilian Senftleben <kernel(a)mail.msdigital.de> Cc: stable(a)vger.kernel.org Fixes: 890d5b40908bfd1a ("usb: gadget: u_ether: fix race in setting MAC address in setup phase") Signed-off-by: Marian Postevca <posteuca(a)mutex.one> --- drivers/usb/gadget/function/u_ether.c | 11 +++++++++-- 1 file changed, 9 insertions(+), 2 deletions(-) diff --git a/drivers/usb/gadget/function/u_ether.c b/drivers/usb/gadget/function/u_ether.c index 271bd08f4a255..3f053b11e2cee 100644 --- a/drivers/usb/gadget/function/u_ether.c +++ b/drivers/usb/gadget/function/u_ether.c @@ -772,9 +772,13 @@ struct eth_dev *gether_setup_name(struct usb_gadget *g, dev->qmult = qmult; snprintf(net->name, sizeof(net->name), "%s%%d", netname); - if (get_ether_addr(dev_addr, net->dev_addr)) + if (get_ether_addr(dev_addr, net->dev_addr)) { + net->addr_assign_type = NET_ADDR_RANDOM; dev_warn(&g->dev, "using random %s ethernet address\n", "self"); + } else { + net->addr_assign_type = NET_ADDR_SET; + } if (get_ether_addr(host_addr, dev->host_mac)) dev_warn(&g->dev, "using random %s ethernet address\n", "host"); @@ -831,6 +835,9 @@ struct net_device *gether_setup_name_default(const char *netname) INIT_LIST_HEAD(&dev->tx_reqs); INIT_LIST_HEAD(&dev->rx_reqs); + /* by default we always have a random MAC address */ + net->addr_assign_type = NET_ADDR_RANDOM; + skb_queue_head_init(&dev->rx_frames); /* network device setup */ @@ -868,7 +875,6 @@ int gether_register_netdev(struct net_device *net) g = dev->gadget; memcpy(net->dev_addr, dev->dev_mac, ETH_ALEN); - net->addr_assign_type = NET_ADDR_RANDOM; status = register_netdev(net); if (status < 0) { @@ -908,6 +914,7 @@ int gether_set_dev_addr(struct net_device *net, const char *dev_addr) if (get_ether_addr(dev_addr, new_addr)) return -EINVAL; memcpy(dev->dev_mac, new_addr, ETH_ALEN); + net->addr_assign_type = NET_ADDR_SET; return 0; } EXPORT_SYMBOL_GPL(gether_set_dev_addr); -- 2.35.1

[PATCH MANUALSEL 5.17 1/3] KVM: x86: disable preemption while updating apicv inhibition

by Sasha Levin

From: Maxim Levitsky <mlevitsk(a)redhat.com> [ Upstream commit 66c768d30e64e1280520f34dbef83419f55f3459 ] Currently nothing prevents preemption in kvm_vcpu_update_apicv. On SVM, If the preemption happens after we update the vcpu->arch.apicv_active, the preemption itself will 'update' the inhibition since the AVIC will be first disabled on vCPU unload and then enabled, when the current task is loaded again. Then we will try to update it again, which will lead to a warning in __avic_vcpu_load, that the AVIC is already enabled. Fix this by disabling preemption in this code.

[PATCH 4.19] usb: gadget: u_ether: fix regression in setting fixed MAC address

by Marian Postevca

commit b337af3a4d6147000b7ca6b3438bf5c820849b37 upstream. In systemd systems setting a fixed MAC address through the "dev_addr" module argument fails systematically. When checking the MAC address after the interface is created it always has the same but different MAC address to the one supplied as argument. This is partially caused by systemd which by default will set an internally generated permanent MAC address for interfaces that are marked as having a randomly generated address. Commit 890d5b40908bfd1a ("usb: gadget: u_ether: fix race in setting MAC address in setup phase") didn't take into account the fact that the interface must be marked as having a set MAC address when it's set as module argument. Fixed by marking the interface with NET_ADDR_SET when the "dev_addr" module argument is supplied.

[PATCH AUTOSEL 4.9 1/3] mei: me: set internal pg flag to off on hardware reset
