2019-11-07USB: idmouse: simplify disconnect handlingJohan Hovold
Since commit d4ead16f50f9 ("USB: prevent char device open/deregister race") core prevents further calls to open() after usb_deregister_dev() returns so there's no need to use the interface data for synchronisation. This effectively reverts commit 54d2bc068fd2 ("USB: fix locking in idmouse") with respect to the open-disconnect race. Note that the driver already uses a present flag to suppress I/O post disconnect (even if all USB I/O take place at open).

As Mathias pointed out, the hub enters Cold Attach Status state and requires a warm reset. However usb_reset_device() bails out early when the device is in suspended state, as its callers port_event() and hub_event() don't always resume the device. Since there's nothing wrong to reset a suspended device, allow usb_reset_device() to do so to solve the issue.

2019-11-04usb: typec: ucsi: Remove struct ucsi_controlHeikki Krogerus
That data structure was used for constructing the commands before executing them, but it was never really useful. Using the structure just complicated the driver. The commands are 64-bit wide, so it is enough to simply fill a u64 variable. No data structures needed. This simplifies the driver considerable and makes it much easier to for example add support for big endian systems later on.

2019-11-04usb: typec: ucsi: Simplified registration and I/O APIHeikki Krogerus
Adding more simplified API for interface registration and read and write operations. The registration is split into separate creation and registration phases. That allows the drivers to properly initialize the interface before registering it if necessary. The read and write operations are supplied in a completely separate struct ucsi_operations that is passed to the ucsi_register() function during registration. The new read and write operations will work more traditionally so that the read callback function reads a requested amount of data from an offset, and the write callback functions write the given data to the offset. The drivers will have to support both non-blocking writing and blocking writing. In blocking writing the driver itself is responsible of waiting for the completion event. The new API makes it possible for the drivers to perform tasks also independently of the core ucsi.c, and that should allow for example quirks to be handled completely in the drivers without the need to touch ucsi.c. The old API is kept until all drivers have been converted to the new API.

There are a number of places in the driver where it fails to maintain __iomem on pointers used to access registers so fixup the warnings by adding these in the appropriate places. Examples of the sparse warnings fixed: drivers/usb/host/oxu210hp-hcd.c:686:9: warning: incorrect type in argument 2 (different address spaces) drivers/usb/host/oxu210hp-hcd.c:686:9: expected void volatile [noderef] <asn:2> *addr drivers/usb/host/oxu210hp-hcd.c:686:9: got void * drivers/usb/host/oxu210hp-hcd.c:686:9: warning: incorrect type in argument 2 (different address spaces) drivers/usb/host/oxu210hp-hcd.c:686:9: expected void volatile [noderef] <asn:2> *addr drivers/usb/host/oxu210hp-hcd.c:686:9: got void * drivers/usb/host/oxu210hp-hcd.c:686:9: warning: incorrect type in argument 2 (different address spaces) drivers/usb/host/oxu210hp-hcd.c:686:9: expected void volatile [noderef] <asn:2> *addr drivers/usb/host/oxu210hp-hcd.c:686:9: got void * drivers/usb/host/oxu210hp-hcd.c:681:16: warning: incorrect type in argument 1 (different address spaces) drivers/usb/host/oxu210hp-hcd.c:681:16: expected void const volatile [noderef] <asn:2> *addr drivers/usb/host/oxu210hp-hcd.c:681:16: got void * Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> Link: https://lore.kernel.org/r/20191017171934.8771-1-ben.dooks@codethink.co.uk Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2019-11-01r8169: fix wrong PHY ID issue with RTL8168dpHeiner Kallweit
As reported in [0] at least one RTL8168dp version has problems establishing a link. This chip version has an integrated RTL8211b PHY, however the chip seems to report a wrong PHY ID, resulting in a wrong PHY driver (for Generic Realtek PHY) being loaded. Work around this issue by adding a hook to r8168dp_2_mdio_read() for returning the correct PHY ID.

2019-11-01net: dsa: bcm_sf2: Fix IMP setup for port different than 8Florian Fainelli
Since it became possible for the DSA core to use a CPU port different than 8, our bcm_sf2_imp_setup() function was broken because it assumes that registers are applicable to port 8. In particular, the port's MAC is going to stay disabled, so make sure we clear the RX_DIS and TX_DIS bits if we are not configured for port 8.

2019-11-01inet: stop leaking jiffies on the wireEric Dumazet
Historically linux tried to stick to RFC 791, 1122, 2003 for IPv4 ID field generation. RFC 6864 made clear that no matter how hard we try, we can not ensure unicity of IP ID within maximum lifetime for all datagrams with a given source address/destination address/protocol tuple. Linux uses a per socket inet generator (inet_id), initialized at connection startup with a XOR of 'jiffies' and other fields that appear clear on the wire. Thiemo Nagel pointed that this strategy is a privacy concern as this provides 16 bits of entropy to fingerprint devices. Let's switch to a random starting point, this is just as good as far as RFC 6864 is concerned and does not leak anything critical.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-queue Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2019-11-01 This series contains updates to e1000, igb, igc, ixgbe, i40e and driver documentation. Lyude Paul fixes an issue where a fatal read error occurs when the device is unplugged from the machine. So change the read error into a warn while the device is still present. Manfred Rudigier found that the i350 device was not apart of the "Media Auto Sense" feature, yet the device supports it. So add the missing i350 device to the check and fix an issue where the media auto sense would flip/flop when no cable was connected to the port causing spurious kernel log messages. I fixed an issue where the fix to resolve receive buffer starvation was applied in more than one place in the driver, one being the incorrect location in the i40e driver. Wenwen Wang fixes a potential memory leak in e1000 where allocated memory is not properly cleaned up in one of the error paths. Jonathan Neuschäfer cleans up the driver documentation to be consistent and remove the footnote reference, since the footnote no longer exists in the documentation. Igor Pylypiv cleans up a duplicate clearing of a bit, no need to clear it twice. v2: Fixed alignment issue in patch 3 of the series based on community feedback. ==================== Signed-off-by: David S.
