* | | bnxt_en: support hwrm_func_drv_unrgtr commandJeffrey Huang2015-12-281-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | During remove_one, the driver should issue hwrm_func_drv_unrgtr command to inform firmware that this function has been unloaded. This is to let firmware keep track of driver present/absent state when driver is gracefully unloaded. A keep alive timer is needed later to keep track of driver state during abnormal shutdown.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a new device driver for a high performance SR-IOV assisted virtual network for IBM System p and IBM System i systems. The SR-IOV VF will be attached to the VIOS partition and mapped to the Linux client via the hypervisor's VNIC protocol that this driver implements. This driver is able to perform basic tx and rx, new features and improvements will be added as they are being developed and tested.

In all of these paths we had very different levels of exception handling. I have updated the driver so that all of the paths should result in a similar state if we fail. Specifically the driver will now unload the mailbox interrupt, free the queue vectors and MSI-X, and then detach the interface. In addition for any of the PCIe related resets I have added a check with the hw_ready function to just make sure the registers are in a readable state prior to reopening the interface.

From Arnd Bergmann. 2) Don't init mutex twice in i40e driver, from Jesse Brandeburg. 3) Fix spurious EBUSY in rhashtable, from Herbert Xu. 4) Missing DMA unmaps in mvpp2 driver, from Marcin Wojtas. 5) Fix race with work structure access in pppoe driver causing corruptions, from Guillaume Nault. 6) Fix OOPS due to sh_eth_rx() not checking whether netdev_alloc_skb() actually succeeded or not, from Sergei Shtylyov. 7) Don't lose flags when settifn IFA_F_OPTIMISTIC in ipv6 code, from Bjørn Mork. 8) VXLAN_HD_RCO defined incorrectly, fix from Jiri Benc. 9) Fix clock source used for cookies in SCTP, from Marcelo Ricardo Leitner. 10) aurora driver needs HAS_DMA dependency, from Geert Uytterhoeven. 11) ndo_fill_metadata_dst op of vxlan has to handle ipv6 tunneling properly as well, from Jiri Benc. 12) Handle request sockets properly in xfrm layer, from Eric Dumazet. 13) Double stats update in ipv6 geneve transmit path, fix from Pravin B Shelar. 14) sk->sk_policy[] needs RCU protection, and as a result xfrm_policy_destroy() needs to free policies using an RCU grace period, from Eric Dumazet. 15) SCTP needs to clone ipv6 tx options in order to avoid use after free, from Eric Dumazet. 16) Missing kbuild export if ila.h, from Stephen Hemminger. 17) Missing mdiobus_alloc() return value checking in mdio-mux.c, from Tobias Klauser. 18) Validate protocol value range in ->create() methods, from Hannes Frederic Sowa. 19) Fix early socket demux races that result in illegal dst reuse, from Eric Dumazet. 20) Validate socket address length in pptp code, from WANG Cong. 21) skb_reorder_vlan_header() uses incorrect offset and can corrupt packets, from Vlad Yasevich. 22) Fix memory leaks in nl80211 registry code, from Ola Olsson. 23) Timeout loop count handing fixes in mISDN, xgbe, qlge, sfc, and qlcnic. From Dan Carpenter. 24) msg.msg_iocb needs to be cleared in recvfrom() otherwise, for example, AF_ALG will interpret it as an async call. From Tadeusz Struk. 25) inetpeer_set_addr_v4 forgets to initialize the 'vif' field, from Eric Dumazet. 26) rhashtable enforces the minimum table size not early enough, breaking how we calculate the per-cpu lock allocations. From Herbert Xu. 27) Fix FCC port lockup in 82xx driver, from Martin Roth. 28) FOU sockets need to be freed using RCU, from Hannes Frederic Sowa. 29) Fix out-of-bounds access in __skb_complete_tx_timestamp() and sock_setsockopt() wrt. timestamp handling.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the Tx flow control is based on reading the hardware state, which is not accurate since it may not reflect the descriptors that are not yet reached the memory. To accurately control the Tx flow, changing it to be software based. Signed-off-by: Iyappan Subramanian <isubramanian@apm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| | * 82xx: FCC: Fixing a bug causing to FCC port lock-upMartin Roth2015-12-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch fixes FCC port lock-up, which occurs as a result of a bug during underrun/collision handling. Within the tx_startup() function in mac-fcc.c, the address of last BD is not calculated correctly. As a result of wrong calculation of the last BD address, the next transmitted BD may be set to an area out of the transmit BD ring. This actually causes to port lock-up and it is not recoverable.
