2022-02-15usb: dwc3: pci: Add "snps,dis_u2_susphy_quirk" for Intel Bay TrailHans de Goede1-1/+12
Commit e0082698b689 ("usb: dwc3: ulpi: conditionally resume ULPI PHY") fixed an issue where ULPI transfers would timeout if any requests where send to the phy sometime after init, giving it enough time to auto-suspend. Commit e5f4ca3fce90 ("usb: dwc3: ulpi: Fix USB2.0 HS/FS/LS PHY suspend regression") changed the behavior to instead of clearing the DWC3_GUSB2PHYCFG_SUSPHY bit, add an extra sleep when it is set. But on Bay Trail devices, when phy_set_mode() gets called during init, this leads to errors like these: [ 28.451522] tusb1210 dwc3.ulpi: error -110 writing val 0x01 to reg 0x0a [ 28.464089] tusb1210 dwc3.ulpi: error -110 writing val 0x01 to reg 0x0a Add "snps,dis_u2_susphy_quirk" to the settings for Bay Trail devices to fix this. This restores the old behavior for Bay Trail devices, since previously the DWC3_GUSB2PHYCFG_SUSPHY bit would get cleared on the first ulpi_read/_write() and then was never set again.

2022-02-11iio: buffer: Fix file related error handling in IIO_BUFFER_GET_FD_IOCTLMathias Krause1-3/+11
If we fail to copy the just created file descriptor to userland, we try to clean up by putting back 'fd' and freeing 'ib'. The code uses put_unused_fd() for the former which is wrong, as the file descriptor was already published by fd_install() which gets called internally by anon_inode_getfd(). This makes the error handling code leaving a half cleaned up file descriptor table around and a partially destructed 'file' object, allowing userland to play use-after-free tricks on us, by abusing the still usable fd and making the code operate on a dangling 'file->private_data' pointer. Instead of leaving the kernel in a partially corrupted state, don't attempt to explicitly clean up and leave this to the process exit path that'll release any still valid fds, including the one created by the previous call to anon_inode_getfd(). Simply return -EFAULT to indicate the error.

When the gadget driver hasn't been (yet) configured, and the cable is connected to a HOST, the SFTDISCON gets cleared unconditionally, so the HOST tries to enumerate it. At the host side, this can result in a stuck USB port or worse. When getting lucky, some dmesg can be observed at the host side: new high-speed USB device number ... device descriptor read/64, error -110 Fix it in drd, by checking the enabled flag before calling dwc2_hsotg_core_connect().

Commit 8c67d06f3fd9 ("usb: Link the ports to the connectors they are attached to") creates a link to the USB Type-C connector for every new port that is added when possible. If component_add() fails, usb_hub_create_port_device() prints a warning but does not unregister the device and does not return errors to the callers. Syzbot reported a "WARNING in component_del()". Fix this issue in usb_hub_create_port_device by calling device_unregister() and returning the errors from component_add().

2022-02-11net: usb: ax88179_178a: Fix out-of-bounds accesses in RX fixupJann Horn1-29/+39
ax88179_rx_fixup() contains several out-of-bounds accesses that can be triggered by a malicious (or defective) USB device, in particular: - The metadata array (hdr_off..hdr_off+2*pkt_cnt) can be out of bounds, causing OOB reads and (on big-endian systems) OOB endianness flips. - A packet can overlap the metadata array, causing a later OOB endianness flip to corrupt data used by a cloned SKB that has already been handed off into the network stack. - A packet SKB can be constructed whose tail is far beyond its end, causing out-of-bounds heap data to be considered part of the SKB's data. I have tested that this can be used by a malicious USB device to send a bogus ICMPv6 Echo Request and receive an ICMPv6 Echo Reply in response that contains random kernel heap data. It's probably also possible to get OOB writes from this on a little-endian system somehow - maybe by triggering skb_cow() via IP options processing -, but I haven't tested that.

Since struct mv88e6xxx_mdio_bus *mdio_bus is the bus->priv of something allocated with mdiobus_alloc_size(), this means that mdiobus_free(bus) will free the memory backing the mdio_bus as well. Therefore, the mdio_bus->list element is freed memory, but we continue to iterate through the list of MDIO buses using that list element. To fix this, use the proper list iterator that handles element deletion by keeping a copy of the list element next pointer.

2022-02-10ice: Avoid RTNL lock when re-creating auxiliary deviceDave Ertman2-1/+5
If a call to re-create the auxiliary device happens in a context that has already taken the RTNL lock, then the call flow that recreates auxiliary device can hang if there is another attempt to claim the RTNL lock by the auxiliary driver. To avoid this, any call to re-create auxiliary devices that comes from an source that is holding the RTNL lock (e.g. netdev notifier when interface exits a bond) should execute in a separate thread. To accomplish this, add a flag to the PF that will be evaluated in the service task and dealt with there.

2022-02-10ice: Fix KASAN error in LAG NETDEV_UNREGISTER handlerDave Ertman1-6/+28
Currently, the same handler is called for both a NETDEV_BONDING_INFO LAG unlink notification as for a NETDEV_UNREGISTER call. This is causing a problem though, since the netdev_notifier_info passed has a different structure depending on which event is passed. The problem manifests as a call trace from a BUG: KASAN stack-out-of-bounds error. Fix this by creating a handler specific to NETDEV_UNREGISTER that only is passed valid elements in the netdev_notifier_info struct for the NETDEV_UNREGISTER event. Also included is the removal of an unbalanced dev_put on the peer_netdev and related braces.

2022-02-10ice: fix IPIP and SIT TSO offloadJesse Brandeburg2-8/+18
The driver was avoiding offload for IPIP (at least) frames due to parsing the inner header offsets incorrectly when trying to check lengths. This length check works for VXLAN frames but fails on IPIP frames because skb_transport_offset points to the inner header in IPIP frames, which meant the subtraction of transport_header from inner_network_header returns a negative value (-20). With the code before this patch, everything continued to work, but GSO was being used to segment, causing throughputs of 1.5Gb/s per thread. After this patch, throughput is more like 10Gb/s per thread for IPIP traffic.

Single page and coherent memory blocks can use different DMA masks when the macb accesses physical memory directly. The kernel is clever enough to allocate pages that fit into the requested address width. When using the ARM SMMU, the DMA mask must be the same for single pages and big coherent memory blocks.

[Why] pflip interrupt order are mapped 1 to 1 to otg id. e.g. if irq_src=26 corresponds to otg0 then 27->otg1, 28->otg2... Linux DM registers pflip interrupts per number of crtcs. In fused pipe case crtc numbers can be less than otg id. e.g. if one pipe out of 3(otg#0-2) is fused adev->mode_info.num_crtc=2 so DM only registers irq_src 26,27. This is a bug since if pipe#2 remains unfused DM never gets otg2 pflip interrupt (irq_src=28) That may results in gfx failure due to pflip timeout.
