2018-04-20afs: Fix server record deletionDavid Howells
AFS server records get removed from the net->fs_servers tree when they're deleted, but not from the net->fs_addresses{4,6} lists, which can lead to an oops in afs_find_server() when a server record has been removed, for instance during rmmod. Fix this by deleting the record from the by-address lists before posting it for RCU destruction. The reason this hasn't been noticed before is that the fileserver keeps probing the local cache manager, thereby keeping the service record alive, so the oops would only happen when a fileserver eventually gets bored and stops pinging or if the module gets rmmod'd and a call comes in from the fileserver during the window between the server records being destroyed and the socket being closed. The oops looks something like: BUG: unable to handle kernel NULL pointer dereference at 000000000000001c ...

2018-04-20qed* : Add new TLV to request PF to update MAC in bulletin boardShahed Shaikh
There may be a need for VF driver to request PF to explicitly update its bulletin with a MAC address. e.g. When user assigns a MAC address to VF while VF is still down, and PF's bulletin board contains different MAC address, in this case, when VF's interface is brought up, it gets loaded with MAC address from bulletin board which is not desirable. To handle this corner case, we need a new TLV to request PF to update its bulletin board with suggested MAC. This request will be honored only for trusted VFs.

2018-04-20qed* : use trust mode to allow VF to override forced MACShahed Shaikh
As per existing behavior, when PF sets a MAC address for a VF (also called as forced MAC), VF is not allowed to change its MAC address afterwards. This puts the limitation on few use cases such as bonding of VFs, where bonding driver asks VF to change its MAC address. This patch uses a VF trust mode to allow VF to change its MAC address in spite PF has set a forced MAC for that VF. Signed-off-by: Shahed Shaikh <shahed.shaikh@cavium.com> Signed-off-by: David S.

Currently, on a new link creation or when 'remote' address parameter is updated, an MTU is not changed and always equals 1500. When a lower device has a larger MTU, it might not be efficient, e.g. for UDP, and requires the manual MTU adjustments to match the MTU of the lower device. This patch tries to automate this process, finds a lower device using the 'remote' address parameter, then uses its MTU to tune GENEVE's MTU: * on a new link creation * when 'remote' parameter is changed Also with this patch, the MTU from a user, on a new link creation, is passed to geneve_change_mtu() where it is verified, and MTU adjustments with a lower device is skipped in that case. Prior that change, it was possible to set the invalid MTU values on a new link creation. Signed-off-by: Alexey Kodanev <alexey.kodanev@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>

GhantaKrishnamurthy MohanKrishna says: ==================== tipc: Confgiuration of MTU for media UDP Systematic measurements have shown that an emulated MTU of 14k for UDP bearers is the optimal value for maximal throughput. Accordingly, the default MTU of UDP bearers is changed to 14k. We also provide users with a fallback option from this value, by providing support to configure MTU for UDP bearers. The following options are introduced which are symmetrical to the design of confguring link tolerance. - Configure media with new MTU value, which will take effect on links going up after the moment it was configured. Alternatively, the bearer has to be disabled and re-enabled, for existing links to reflect the configured value. - Configure bearer with new MTU value, which take effect on running links dynamically. Please note: - User has to change MTU at both endpoints, otherwise the link will fall back to smallest MTU after a reset. - Failover from a link with higher MTU to a link with lower MTU ==================== Signed-off-by: David S.

Currently, we have option to configure MTU of UDP media. The configured MTU takes effect on the links going up after that moment. I.e, a user has to reset bearer to have new value applied across its links. This is confusing and disturbing on a running cluster. We now introduce the functionality to change the default UDP bearer MTU in struct tipc_bearer. Additionally, the links are updated dynamically, without any need for a reset, when bearer value is changed. We leverage the existing per-link functionality and the design being symetrical to the confguration of link tolerance.

Currently, all bearers are configured with MTU value same as the underlying L2 device. However, in case of bearers with media type UDP, higher throughput is possible with a fixed and higher emulated MTU value than adapting to the underlying L2 MTU. In this commit, we introduce a parameter mtu in struct tipc_media and a default value is set for UDP. A default value of 14k was determined by experimentation and found to have a higher throughput than 16k. MTU for UDP bearers are assigned the above set value of media MTU.

2018-04-20net: ethernet: ave: add support for phy-mode setting of system controllerKunihiko Hayashi
This patch adds support for specifying system controller that configures phy-mode setting. According to the DT property "phy-mode", it's necessary to configure the controller, which is used to choose the settings of the MAC suitable, for example, mdio pin connections, internal clocks, and so on. Supported phy-modes are SoC-dependent. The driver allows phy-mode to set "internal" if the SoC has a built-in PHY, and {"mii", "rmii", "rgmii"} if the SoC supports each mode. So we have to check whether the phy-mode is valid or not. This adds the following features for each SoC: - check whether the SoC supports the specified phy-mode - configure the controller accroding to phy-mode The DT property accepts one argument to distinguish them for multiple MAC instances. ethernet@65000000 { ... socionext,syscon-phy-mode = <&soc_glue 0>; }; ethernet@65200000 { ... socionext,syscon-phy-mode = <&soc_glue 1>; }; Signed-off-by: Kunihiko Hayashi <hayashi.kunihiko@socionext.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Signed-off-by: David S.

2018-04-20net: ethernet: ave: add multiple clocks and resets support as required propertyKunihiko Hayashi
When the link is becoming up for Pro4 SoC, the kernel is stalled due to some missing clocks and resets. The AVE block for Pro4 is connected to the GIO bus in the SoC. Without its clock/reset, the access to the AVE register makes the system stall. In the same way, another MAC clock for Giga-bit Connection and the PHY clock are also required for Pro4 to activate the Giga-bit feature and to recognize the PHY. To satisfy these requirements, this patch adds support for multiple clocks and resets, and adds the clock-names and reset-names to the binding because we need to distinguish clock/reset for the AVE main block and the others. Also, make the resets a required property. Currently, "reset is optional" relies on that the bootloader or firmware has deasserted the reset before booting the kernel. Drivers should work without such expectation.

2018-04-20net: phy: mdio-boardinfo: Allow recursive mdiobus_register()Andrew Lunn
mdiobus_register will search for any mdiobus board info registered for the bus being registered. If found, it will probe devices on the bus. That device, if for example it is an ethernet switch, may then try to register an mdio bus. Thus we need to allow recursive calls to mdiobus_register. Holding the mdio_board_lock will cause a deadlock during this recursion. Release the lock and use list_for_each_entry_safe. Signed-off-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: David S.

2018-04-19net/smc: fix shutdown in state SMC_LISTENUrsula Braun
Calling shutdown with SHUT_RD and SHUT_RDWR for a listening SMC socket crashes, because commit 127f49705823 ("net/smc: release clcsock from tcp_listen_worker") releases the internal clcsock in smc_close_active() and sets smc->clcsock to NULL. For SHUT_RD the smc_close_active() call is removed. For SHUT_RDWR the kernel_sock_shutdown() call is omitted, since the clcsock is already released.

2018-04-19bnxt_en: Fix memory fault in bnxt_ethtool_init()Vasundhara Volam
In some firmware images, the length of BNX_DIR_TYPE_PKG_LOG nvram type could be greater than the fixed buffer length of 4096 bytes allocated by the driver. This was causing HWRM_NVM_READ to copy more data to the buffer than the allocated size, causing general protection fault. Fix the issue by allocating the exact buffer length returned by HWRM_NVM_FIND_DIR_ENTRY, instead of 4096. Move the kzalloc() call into the bnxt_get_pkgver() function.

2018-04-19virtio_net: split out ctrl bufferMichael S. Tsirkin
When sending control commands, virtio net sets up several buffers for DMA. The buffers are all part of the net device which means it's actually allocated by kvmalloc so it's in theory (on extreme memory pressure) possible to get a vmalloc'ed buffer which on some platforms means we can't DMA there.
