Sergei Shtylyov says: ==================== sh_eth: E-MAC interrupt handler cleanups Here's a set of 3 patches against DaveM's 'net-next.git' repo. I'm cleaning up the E-MAC interrupt handling with the main goal of factoring out the E-MAC interrupt handler into a separate function.

The E-MAC interrupt (EESR.ECI) is not always caused by an error condition, so it really shouldn't be handled by sh_eth_error(). Factor out the E-MAC interrupt handler, sh_eth_emac_interrupt(), removing the ECI bit from the EESR's values throughout the driver...

The driver should only handle the enabled E-MAC interrupts, like it does for the E-DMAC interrupts since commit 3893b273 ("sh_eth: workaround for spurious ECI interrupt"), so mask ECSR with ECSIPR when reading it in sh_eth_error().

Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2017-01-03 This series contains updates to ixgbe and ixgbevf only. Emil fixes ixgbe to use the NVM settings for FEC, so do not override the settings. Fixed the indirection table for x550, where newer devices can support up to 64 RSS queues. Extends the rtnl_lock() to protect the call to netif_device_detach() and ixgbe_clear_interrupt_scheme() to avoid against a double free WARN and/or a BUG in free_msi_irqs(). Fixed AER error handling by making sure that the driver frees the IRQs in ixgbe_io_error_detected() when responding to a PCIe AER error, and to restore them when the interface recovers. Tony updates the driver to report the driver version to the firmware using the host interface command for x550 devices. Fixed the PHY reset check for x550em_ext_t PHY type. Fixed bounds checking for x540 devices to ensure the index is valid for the LED function. Fixed the BaseT adapters which support 100Mb capability and were not reporting the capability. Ken Cox adds a missing check for the trusted bit before trying to set the MACVLAN MAC address. Yusuke Suzuki fixes an issue with 82599 and x540 devices where receive timestamps were not working becase the bitwise operation for RX_HWSTAMP falg was incorrect. Don ensures that x553 KR/KX devices correctly advertise link speeds. Adds the mailbox message to allow for VF promiscuous mode support. Mark fixes two issues with EEPROM access, where the semaphore was not being held until the entire response was read and the acquiring/releasing of the semaphore is slow. Cleaned up firmware version method and functions which are no longer used.

There are two problems with EEPROM access. One is that it needs to hold the semaphore until the entire response is read or else the response can be corrupted by other firmware accesses. The second problem is that acquiring and releasing the semaphore is slow, so it should be taken and released once when multiple EEPROM accesses will be done. Both of these issues can be solved by adding a new function, ixgbe_hic_unlocked, to issue firmware commands that will assume that the caller has acquired the needed semaphore.

There are two methods for setting mac addresses in a Macvlan, that differentiate themselves in the function macvlan_set_mac_Address. If the macvlan mode is passthru, then we use the dev_set_mac_address method, otherwise we use the dev_uc api via macvlan_sync_addresses. The latter method (which would stem from using any non-passthru mode, like bridge, or vepa), calls down into the driver in a path that terminates in ixgbevf_set_uc_addr_vf, which sends a IXGBE_VF_SET_MACVLAN message, which causes the pf to spawn the noted error message. This occurs because it appears that the guest is trying to delete the mac address of the macvlan before adding another. The other path in macvlan_set_mac_address uses dev_set_mac_address, which calls into ixgbevf_set_mac which uses the IXGBE_VF_SET_MAC_ADDR to the pf to set the macvlan mac address. The discrepancy here is in the handlers. The handler function for IXGBE_VF_SET_MAC_ADDR (ixgbe_set_vf_mac_addr) has a check for the vfinfo[].trusted bit to allow the operation if the vf is trusted. In comparison, the IXGBE_VF_SET_MACVLAN message handler (ixgbe_set_vf_macvlan_msg) has no such check of the trusted bit.

Jon Maloy says: ==================== tipc: improve interaction socket-link We fix a very real starvation problem that may occur when a link encounters send buffer congestion. At the same time we make the interaction between the socket and link layer simpler and more consistent. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>
-
由 Jon Paul Maloy 提交于
The socket code currently handles link congestion by either blocking and trying to send again when the congestion has abated, or just returning to the user with -EAGAIN and let him re-try later. This mechanism is prone to starvation, because the wakeup algorithm is non-atomic. During the time the link issues a wakeup signal, until the socket wakes up and re-attempts sending, other senders may have come in between and occupied the free buffer space in the link. This in turn may lead to a socket having to make many send attempts before it is successful. In extremely loaded systems we have observed latency times of several seconds before a low-priority socket is able to send out a message. In this commit, we simplify this mechanism and reduce the risk of the described scenario happening. When a message is attempted sent via a congested link, we now let it be added to the link's backlog queue anyway, thus permitting an oversubscription of one message per source socket. We still create a wakeup item and return an error code, hence instructing the sender to block or stop sending. Only when enough space has been freed up in the link's backlog queue do we issue a wakeup event that allows the sender to continue with the next message, if any. The fact that a socket now can consider a message sent even when the link returns a congestion code means that the sending socket code can be simplified. Also, since this is a good opportunity to get rid of the obsolete 'mtu change' condition in the three socket send functions, we now choose to refactor those functions completely.

Although TPACKET_V3 Rx has some benefits over TPACKET_V2 Rx, *_v3 does not currently have TX_RING support. As a result an application that wants the best perf for Tx and Rx (e.g. to handle request/response transacations) ends up needing 2 sockets, one with *_v2 for Tx and another with *_v3 for Rx. This patch enables TPACKET_V2 compatible Tx features in TPACKET_V3 so that an application can use a single descriptor to get the benefits of _v3 RX_RING and _v2 TX_RING. An application may do a block-send by first filling up multiple frames in the Tx ring and then triggering a transmit. This patch only support fixed size Tx frames for TPACKET_V3, and requires that tp_next_offset must be zero. Signed-off-by: NSowmini Varadhan <sowmini.varadhan@oracle.com> Signed-off-by: NDavid S.
