2019-10-23mlxsw: spectrum: Use guaranteed buffer size as pool size limitPetr Machata
There are two resources associated with shared buffer size: cap_total_buffer_size, and cap_guaranteed_shared_buffer. So far, mlxsw has been using the former as a limit to determine how large a pool size is allowed to be. However, the total size also includes headrooms and reserved space, which really cannot be used for shared buffer pools. Therefore convert mlxsw to use the latter resource as a limit. Adjust hard-coded pool sizes to be the guaranteed size minus 256000 bytes for CPU port pool. On Spectrum-1 that actually leads to an increase. A follow-up patch will have this size calculated automatically. Signed-off-by: Petr Machata <petrm@mellanox.com> Signed-off-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S.

2019-10-23net: phy: broadcom: add 1000Base-X support for BCM54616STao Ren
The BCM54616S PHY cannot work properly in RGMII->1000Base-X mode, mainly because genphy functions are designed for copper links, and 1000Base-X (clause 37) auto negotiation needs to be handled differently. This patch enables 1000Base-X support for BCM54616S by customizing 3 driver callbacks, and it's verified to be working on Facebook CMM BMC platform (RGMII->1000Base-KX): - probe: probe callback detects PHY's operation mode based on INTERF_SEL[1:0] pins and 1000X/100FX selection bit in SerDES 100-FX Control register. - config_aneg: calls genphy_c37_config_aneg when the PHY is running in 1000Base-X mode; otherwise, genphy_config_aneg will be called. - read_status: calls genphy_c37_read_status when the PHY is running in 1000Base-X mode; otherwise, genphy_read_status will be called. Note: BCM54616S PHY can also be configured in RGMII->100Base-FX mode, and 100Base-FX support is not available as of now.

2019-10-23compat_ioctl: ppp: move simple commands into ppp_generic.cArnd Bergmann
All ppp commands that are not already handled in ppp_compat_ioctl() are compatible, so they can now handled by calling the native ppp_ioctl() directly. Without CONFIG_BLOCK, the generic compat_ioctl table is now empty, so add a check to avoid a build failure in the looking function for that configuration.

2019-10-23compat_ioctl: handle PPPIOCGIDLE for 64-bit time_tArnd Bergmann
The ppp_idle structure is defined in terms of __kernel_time_t, which is defined as 'long' on all architectures, and this usage is not affected by the y2038 problem since it transports a time interval rather than an absolute time. However, the ppp user space defines the same structure as time_t, which may be 64-bit wide on new libc versions even on 32-bit architectures. It's easy enough to just handle both possible structure layouts on all architectures, to deal with the possibility that a user space ppp implementation comes with its own ppp_idle structure definition, as well as to document the fact that the driver is y2038-safe. Doing this also avoids the need for a special compat mode translation, since 32-bit and 64-bit kernels now support the same interfaces. The old 32-bit structure is also available on native 64-bit architectures now, but this is harmless.

Extend the size of QSFP EEPROM for the cable types SSF8436 and SFF8636 from 256 to 640 bytes in order to expose all the EEPROM pages by ethtool. For SFF-8636 and SFF-8436 specifications, the driver exposes 256 bytes of data for ethtool's get_module_eeprom() callback. This is because the driver uses the below defines to specify SFF module length in ethtool's get_module_info() callback: 'ETH_MODULE_SFF_8636_LEN' and 'ETH_MODULE_SFF_8436_LEN' (both are 256). As a result of exposing 256 bytes only, ethtool shows wrong "zero" info for pages 1, 2, 3. The patch changes the length returned by callback for get_module_info() to the values from the next defines: 'ETH_MODULE_SFF_8636_MAX_LEN' and 'ETH_MODULE_SFF_8436_MAX_LEN' (both are 640) to allow exposing of upper page 1, 2 and 3.

2019-10-22ath10k: Fix a NULL-ptr-deref bug in ath10k_usb_alloc_urb_from_pipeHui Peng
The `ar_usb` field of `ath10k_usb_pipe_usb_pipe` objects are initialized to point to the containing `ath10k_usb` object according to endpoint descriptors read from the device side, as shown below in `ath10k_usb_setup_pipe_resources`: for (i = 0; i < iface_desc->desc.bNumEndpoints; ++i) { endpoint = &iface_desc->endpoint[i].desc; // get the address from endpoint descriptor pipe_num = ath10k_usb_get_logical_pipe_num(ar_usb, endpoint->bEndpointAddress, &urbcount); ...... // select the pipe object pipe = &ar_usb->pipes[pipe_num]; // initialize the ar_usb field pipe->ar_usb = ar_usb; } The driver assumes that the addresses reported in endpoint descriptors from device side to be complete. If a device is malicious and does not report complete addresses, it may trigger NULL-ptr-deref `ath10k_usb_alloc_urb_from_pipe` and `ath10k_usb_free_urb_to_pipe`. This patch fixes the bug by preventing potential NULL-ptr-deref.

2019-10-22rtl8xxxu: fix RTL8723BU connection failure issue after warm rebootChris Chiu
The RTL8723BU has problems connecting to AP after each warm reboot. Sometimes it returns no scan result, and in most cases, it fails the authentication for unknown reason. However, it works totally fine after cold reboot. Compare the value of register SYS_CR and SYS_CLK_MAC_CLK_ENABLE for cold reboot and warm reboot, the registers imply that the MAC is already powered and thus some procedures are skipped during driver initialization. Double checked the vendor driver, it reads the SYS_CR and SYS_CLK_MAC_CLK_ENABLE also but doesn't skip any during initialization based on them. This commit only tells the RTL8723BU to do full initialization without checking MAC status.

2019-10-21Merge branch '1GbE' of ↵Jakub Kicinski
git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== 1GbE Intel Wired LAN Driver Updates 2019-10-21 This series contains updates to e1000e and igc only. Sasha adds stream control transmission protocol (SCTP) CRC checksum support for igc. Also added S0ix support to the e1000e driver. Then added multicast support by adding the address list to the MTA table and providing the option for IPv6 address for igc. In addition, added receive checksum support to igc as well. Lastly, cleaned up some code that was not fully implemented yet for the VLAN filter table array. v2: Dropped patch 1 & 2 from the original series. Patch 1 is being sent to 'net' tree as a fix and patch 2 implementation needs to be re-worked. Updated the patch to add support for S0ix to fix the reverse Xmas tree issues and made the entry/exit functions void since they constantly returned success. All based on community feedback. v3: Cleaned up patch 4 of the series based on feedback from the community. Cleaned up a stray comma in a code comment and removed the 'inline' of a function that would be inlined by the compiler anyways. ==================== Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com>
2019-10-21r8152: add device id for Lenovo ThinkPad USB-C Dock Gen 2Kazutoshi Noguchi
This device is sold as 'ThinkPad USB-C Dock Gen 2 (40AS)'. Chipset is RTL8153 and works with r8152. Without this, the generic cdc_ether grabs the device, and the device jam connected networks up when the machine suspends.

Instead of superseded function marvell_set_downshift() we can use new function m88e1111_set_downshift() in m88e1116r_config_init(). For this m88e1116r_config_init() has to be moved in the code.

2019-10-21net: phy: marvell: support downshift as PHY tunableHeiner Kallweit
So far downshift is implemented for one small use case only and can't be controlled from userspace. So let's implement this feature properly as a PHY tunable so that it can be controlled via ethtool. More Marvell PHY's may support downshift, but I restricted it for now to the ones where I have the datasheet. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S.
