2019-10-27usb: cdns3: gadget: Don't manage pullupsRoger Quadros1-4/+0
The USB gadget core is supposed to manage pullups of the controller. Don't manage pullups from within the controller driver. Otherwise, function drivers are not able to keep the controller disconnected from the bus till they are ready.

2019-10-27usb: dwc3: remove the call trace of USBx_GFLADJYinbo Zhu1-2/+1
layerscape board sometimes reported some usb call trace, that is due to kernel sent LPM tokerns automatically when it has no pending transfers and think that the link is idle enough to enter L1, which procedure will ask usb register has a recovery,then kernel will compare USBx_GFLADJ and set GFLADJ_30MHZ, GFLADJ_30MHZ_REG until GFLADJ_30MHZ is equal 0x20, if the conditions were met then issue occur, but whatever the conditions whether were met that usb is all need keep GFLADJ_30MHZ of value is 0x20 (xhci spec ask use GFLADJ_30MHZ to adjust any offset from clock source that generates the clock that drives the SOF counter, 0x20 is default value of it)That is normal logic, so need remove the call trace.

2019-10-27usb: gadget: configfs: fix concurrent issue between composite APIsPeter Chen1-5/+105
We meet several NULL pointer issues if configfs_composite_unbind and composite_setup (or composite_disconnect) are running together. These issues occur when do the function switch stress test, the configfs_compsoite_unbind is called from user mode by echo "" to /sys/../UDC entry, and meanwhile, the setup interrupt or disconnect interrupt occurs by hardware. The composite_setup will get the cdev from get_gadget_data, but configfs_composite_unbind will set gadget data as NULL, so the NULL pointer issue occurs. This concurrent is hard to reproduce by native kernel, but can be reproduced by android kernel. In this commit, we introduce one spinlock belongs to structure gadget_info since we can't use the same spinlock in usb_composite_dev due to exclusive running together between composite_setup and configfs_composite_unbind. And one bit flag 'unbind' to indicate the code is at unbind routine, this bit is needed due to we release the lock at during configfs_composite_unbind sometimes, and composite_setup may be run at that time.

In dwc3_pci_probe a call to platform_device_alloc allocates a device which is correctly put in case of error except one case: when the call to platform_device_add_properties fails it directly returns instead of going to error handling.

2019-10-27usb: gadget: composite: Fix possible double free memory bugChandana Kishori Chiluveru1-0/+4
composite_dev_cleanup call from the failure of configfs_composite_bind frees up the cdev->os_desc_req and cdev->req. If the previous calls of bind and unbind is successful these will carry stale values. Consider the below sequence of function calls: configfs_composite_bind() composite_dev_prepare() - Allocate cdev->req, cdev->req->buf composite_os_desc_req_prepare() - Allocate cdev->os_desc_req, cdev->os_desc_req->buf configfs_composite_unbind() composite_dev_cleanup() - free the cdev->os_desc_req->buf and cdev->req->buf Next composition switch configfs_composite_bind() - If it fails goto err_comp_cleanup will call the composite_dev_cleanup() function composite_dev_cleanup() - calls kfree up with the stale values of cdev->req->buf and cdev->os_desc_req from the previous configfs_composite_bind call. The free call on these stale values leads to double free. Hence, Fix this issue by setting request and buffer pointer to NULL after kfree.

2019-10-26ipv4: fix route update on metric change.Paolo Abeni1-1/+1
Since commit af4d768ad28c ("net/ipv4: Add support for specifying metric of connected routes"), when updating an IP address with a different metric, the associated connected route is updated, too. Still, the mentioned commit doesn't handle properly some corner cases: $ ip addr add dev eth0 192.168.1.0/24 $ ip addr add dev eth0 192.168.2.1/32 peer 192.168.2.2 $ ip addr add dev eth0 192.168.3.1/24 $ ip addr change dev eth0 192.168.1.0/24 metric 10 $ ip addr change dev eth0 192.168.2.1/32 peer 192.168.2.2 metric 10 $ ip addr change dev eth0 192.168.3.1/24 metric 10 $ ip -4 route 192.168.1.0/24 dev eth0 proto kernel scope link src 192.168.1.0 192.168.2.2 dev eth0 proto kernel scope link src 192.168.2.1 192.168.3.0/24 dev eth0 proto kernel scope link src 192.168.2.1 metric 10 Only the last route is correctly updated. The problem is the current test in fib_modify_prefix_metric(): if (!(dev->flags & IFF_UP) || ifa->ifa_flags & (IFA_F_SECONDARY | IFA_F_NOPREFIXROUTE) || ipv4_is_zeronet(prefix) || prefix == ifa->ifa_local || ifa->ifa_prefixlen == 32) Which should be the logical 'not' of the pre-existing test in fib_add_ifaddr(): if (!ipv4_is_zeronet(prefix) && !(ifa->ifa_flags & IFA_F_SECONDARY) && (prefix != addr || ifa->ifa_prefixlen < 32)) To properly negate the original expression, we need to change the last logical 'or' to a logical 'and'.

2019-10-25cxgb4: request the TX CIDX updates to status pageRaju Rangoju1-6/+2
For adapters which support the SGE Doorbell Queue Timer facility, we configured the Ethernet TX Queues to send CIDX Updates to the Associated Ethernet RX Response Queue with CPL_SGE_EGR_UPDATE messages to allow us to respond more quickly to the CIDX Updates. But, this was adding load to PCIe Link RX bandwidth and, potentially, resulting in higher CPU Interrupt load. This patch requests the HW to deliver the CIDX updates to the TX queue status page rather than generating an ingress queue message (as an interrupt). With this patch, the load on RX bandwidth is reduced and a substantial improvement in BW is noticed at lower IO sizes.

2019-10-25netns: fix GFP flags in rtnl_net_notifyid()Guillaume Nault5-26/+29
In rtnl_net_notifyid(), we certainly can't pass a null GFP flag to rtnl_notify(). A GFP_KERNEL flag would be fine in most circumstances, but there are a few paths calling rtnl_net_notifyid() from atomic context or from RCU critical sections. The later also precludes the use of gfp_any() as it wouldn't detect the RCU case. Also, the nlmsg_new() call is wrong too, as it uses GFP_KERNEL unconditionally. Therefore, we need to pass the GFP flags as parameter and propagate it through function calls until the proper flags can be determined. In most cases, GFP_KERNEL is fine. The exceptions are: * openvswitch: ovs_vport_cmd_get() and ovs_vport_cmd_dump() indirectly call rtnl_net_notifyid() from RCU critical section, * rtnetlink: rtmsg_ifinfo_build_skb() already receives GFP flags as parameter. Also, in ovs_vport_cmd_build_info(), let's change the GFP flags used by nlmsg_new(). The function is allowed to sleep, so better make the flags consistent with the ones used in the following ovs_vport_cmd_fill_info() call. Found by code inspection.

2019-10-25net/smc: fix closing of fallback SMC socketsUrsula Braun1-0/+7
For SMC sockets forced to fallback to TCP, the file is propagated from the outer SMC to the internal TCP socket. When closing the SMC socket, the internal TCP socket file pointer must be restored to the original NULL value, otherwise memory leaks may show up (found with CONFIG_DEBUG_KMEMLEAK). The internal TCP socket is released in smc_clcsock_release(), which calls __sock_release() function in net/socket.c. This calls the needed iput(SOCK_INODE(sock)) only, if the file pointer has been reset to the original NULL-value.
