| | | | | | | | | | | | | | | This patch includes change to enable firmware patch simplication feature. This feature is targeted to address the requirement to have independent patch release for firmware. Prior to the 3.2.3.0 firmware, releasing a patch fix for firmware would require changes to bna driver, to use new firmware images. However with these changes, if the new firmware is flashed on to the Adapter, the driver will use the new firmware after checking the patch release byte in the firmware version.

* bna: Enable Multi Buffer RXRasesh Mody2013-12-18
| | | | | | | | | | | | | | | | | | | | | | The CT2 HW supports multi-buffer Rx. This patch provides the necessary changes for bnad to use multi-buffer Rx feature. For BNAD, multi-buffer Rx is by default enabled when MTU is > 4096. For >4096 MTU, q0 data/large buffers are of 2048 size. As the resource requirements of multi-buffer Rx are different new Rx needs to be created to use this feature. ASIC posts multiple completions if frame exceeds buffer size. The last completion is marked with EOP flag. - Separate HQ and DQ enums for resource allocations and configurations. - rx_config and rxq structure changes to pass the correct info from bnad. - DQ depth need not be same as HQ depth. So CQ depth is adjusted accordingly. - Rx CFG frame size is taken from configured MTU. - Rx q0 buffer size is configured from bnad s rx_config when multi-buffer is enabled. - Poll for entire frame completion. - Once EOP completion is received gather the number of vectors used by the frame to submit it to the stack. - Changed MTU to frame size wherever necessary.

Some of the more serious errors include: - drivers which only set their coherent DMA mask if the attempt to set the streaming mask fails. - drivers which test for a NULL dma mask pointer, and then set the dma mask pointer to a location in their module .data section - which will cause problems if the module is reloaded. To counter these, I have introduced two helper functions: - dma_set_mask_and_coherent() takes care of setting both the streaming and coherent masks at the same time, with the correct error handling as specified by the API. - dma_coerce_mask_and_coherent() which resolves the problem of drivers forcefully setting DMA masks. This is more a marker for future work to further clean these locations up - the code which creates the devices really should be initialising these, but to fix that in one go along with this change could potentially be very disruptive. The last thing this series does is prise away some of Linux's addition to "DMA addresses are physical addresses and RAM always starts at zero". We have ARM LPAE systems where all system memory is above 4GB physical, hence having DMA masks interpreted by (eg) the block layers as describing physical addresses in the range 0..DMAMASK fails on these platforms. Santosh Shilimkar addresses this in this series; the patches were copied to the appropriate people multiple times but were ignored. Fixing this also gets rid of some ARM weirdness in the setup of the max*pfn variables, and brings ARM into line with every other Linux architecture as far as those go" * 'for-linus-dma-masks' of git://git.linaro.org/people/rmk/linux-arm: (52 commits) ARM: 7805/1: mm: change max*pfn to include the physical offset of memory ARM: 7797/1: mmc: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7796/1: scsi: Use dma_max_pfn(dev) helper for bounce_limit calculations ARM: 7795/1: mm: dma-mapping: Add dma_max_pfn(dev) helper function ARM: 7794/1: block: Rename parameter dma_mask to max_addr for blk_queue_bounce_limit() ARM: DMA-API: better handing of DMA masks for coherent allocations ARM: 7857/1: dma: imx-sdma: setup dma mask DMA-API: firmware/google/gsmi.c: avoid direct access to DMA masks DMA-API: dcdbas: update DMA mask handing DMA-API: dma: edma.c: no need to explicitly initialize DMA masks DMA-API: usb: musb: use platform_device_register_full() to avoid directly messing with dma masks DMA-API: crypto: remove last references to 'static struct device *dev' DMA-API: crypto: fix ixp4xx crypto platform device support DMA-API: others: use dma_set_coherent_mask() DMA-API: staging: use dma_set_coherent_mask() DMA-API: usb: use new dma_coerce_mask_and_coherent() DMA-API: usb: use dma_set_coherent_mask() DMA-API: parport: parport_pc.c: use dma_coerce_mask_and_coherent() DMA-API: net: octeon: use dma_coerce_mask_and_coherent() DMA-API: net: nxp/lpc_eth: use dma_coerce_mask_and_coherent() ...
| * DMA-API: net: brocade/bna/bnad.c: fix 32-bit DMA mask handlingRussell King2013-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fallback to 32-bit DMA mask is rather odd: if (!dma_set_mask(&pdev->dev, DMA_BIT_MASK(64)) && !dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(64))) { *using_dac = true; } else { err = dma_set_mask(&pdev->dev, DMA_BIT_MASK(32)); if (err) { err = dma_set_coherent_mask(&pdev->dev, DMA_BIT_MASK(32)); if (err) goto release_regions; } This means we only try and set the coherent DMA mask if we failed to set a 32-bit DMA mask, and only if both fail do we fail the driver. Adjust this so that if either setting fails, we fail the driver - and thereby end up properly setting both the DMA mask and the coherent DMA mask in the fallback case.

The only difference from the one I made the other day is that this has Eliezer's interface renames and the timeout handling changes made based upon your feedback, as well as a few bug fixes that have trickeled in. Highlights: 1) Low latency device polling, eliminating the cost of interrupt handling and context switches. Allows direct polling of a network device from socket operations, such as recvmsg() and poll(). Currently ixgbe, mlx4, and bnx2x support this feature. Full high level description, performance numbers, and design in commit 0a4db187a999 ("Merge branch 'll_poll'") From Eliezer Tamir. 2) With the routing cache removed, ip_check_mc_rcu() gets exercised more than ever before in the case where we have lots of multicast addresses. Use a hash table instead of a simple linked list, from Eric Dumazet. 3) Add driver for Atheros CQA98xx 802.11ac wireless devices, from Bartosz Markowski, Janusz Dziedzic, Kalle Valo, Marek Kwaczynski, Marek Puzyniak, Michal Kazior, and Sujith Manoharan. 4) Support reporting the TUN device persist flag to userspace, from Pavel Emelyanov. 5) Allow controlling network device VF link state using netlink, from Rony Efraim. 6) Support GRE tunneling in openvswitch, from Pravin B Shelar. 7) Adjust SOCK_MIN_RCVBUF and SOCK_MIN_SNDBUF for modern times, from Daniel Borkmann and Eric Dumazet. 8) Allow controlling of TCP quickack behavior on a per-route basis, from Cong Wang. 9) Several bug fixes and improvements to vxlan from Stephen Hemminger, Pravin B Shelar, and Mike Rapoport. In particular, support receiving on multiple UDP ports. 10) Major cleanups, particular in the area of debugging and cookie lifetime handline, to the SCTP protocol code. From Daniel Borkmann. 11) Allow packets to cross network namespaces when traversing tunnel devices. From Nicolas Dichtel. 12) Allow monitoring netlink traffic via AF_PACKET sockets, in a manner akin to how we monitor real network traffic via ptype_all. From Daniel Borkmann. 13) Several bug fixes and improvements for the new alx device driver, from Johannes Berg. 14) Fix scalability issues in the netem packet scheduler's time queue, by using an rbtree. From Eric Dumazet. 15) Several bug fixes in TCP loss recovery handling, from Yuchung Cheng. 16) Add support for GSO segmentation of MPLS packets, from Simon Horman. 17) Make network notifiers have a real data type for the opaque pointer that's passed into them. Use this to properly handle network device flag changes in arp_netdev_event(). From Jiri Pirko and Timo Teräs. 18) Convert several drivers over to module_pci_driver(), from Peter Huewe. 19) tcp_fixup_rcvbuf() can loop 500 times over loopback, just use a O(1) calculation instead. From Eric Dumazet. 20) Support setting of explicit tunnel peer addresses in ipv6, just like ipv4. From Nicolas Dichtel. 21) Protect x86 BPF JIT against spraying attacks, from Eric Dumazet. 22) Prevent a single high rate flow from overruning an individual cpu during RX packet processing via selective flow shedding. From Willem de Bruijn. 23) Don't use spinlocks in TCP md5 signing fast paths, from Eric Dumazet. 24) Don't just drop GSO packets which are above the TBF scheduler's burst limit, chop them up so they are in-bounds instead. Also from Eric Dumazet. 25) VLAN offloads are missed when configured on top of a bridge, fix from Vlad Yasevich. 26) Support IPV6 in ping sockets. From Lorenzo Colitti. 27) Receive flow steering targets should be updated at poll() time too, from David Majnemer. 28) Fix several corner case regressions in PMTU/redirect handling due to the routing cache removal, from Timo Teräs. 29) We have to be mindful of ipv4 mapped ipv6 sockets in upd_v6_push_pending_frames(). From Hannes Frederic Sowa. 30) Fix L2TP sequence number handling bugs, from James Chapman." * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1214 commits) drivers/net: caif: fix wrong rtnl_is_locked() usage drivers/net: enic: release rtnl_lock on error-path vhost-net: fix use-after-free in vhost_net_flush net: mv643xx_eth: do not use port number as platform device id net: sctp: confirm route during forward progress virtio_net: fix race in RX VQ processing virtio: support unlocked queue poll net/cadence/macb: fix bug/typo in extracting gem_irq_read_clear bit Documentation: Fix references to defunct linux-net@vger.kernel.org net/fs: change busy poll time accounting net: rename low latency sockets functions to busy poll bridge: fix some kernel warning in multicast timer sfc: Fix memory leak when discarding scattered packets sit: fix tunnel update via netlink dt:net:stmmac: Add dt specific phy reset callback support. dt:net:stmmac: Add support to dwmac version 3.610 and 3.710 dt:net:stmmac: Allocate platform data only if its NULL. net:stmmac: fix memleak in the open method ipv6: rt6_check_neigh should successfully verify neigh if no NUD information are available net: ipv6: fix wrong ping_v6_sendmsg return value ...

The xen-netback conflict was overlapping changes involving the handling of the notify list in xen_netbk_rx_action(). Batman conflict resolution provided by Antonio Quartulli, basically keep everything in both conflict hunks. The nl80211 conflict is a little more involved. In 'net' we added a dynamic memory allocation to nl80211_dump_wiphy() to fix a race that Linus reported. Meanwhile in 'net-next' the handlers were converted to use pre and post doit handlers which use a flag to determine whether to hold the RTNL mutex around the operation. However, the dump handlers to not use this logic. Instead they have to explicitly do the locking. There were apparent bugs in the conversion of nl80211_dump_wiphy() in that we were not dropping the RTNL mutex in all the return paths, and it seems we very much should be doing so. So I fixed that whilst handling the overlapping changes. To simplify the initial returns, I take the RTNL mutex after we try to allocate 'tb'. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | User should not be allowed to delete base function of eth port. Add a new field to the bfa ioc attributes structure to indicate if the given ioc is default function on the port or not. Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S.

| * | bna: Fix Ucast Failure HandlingRasesh Mody2013-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Failure of the UCAST set for base mac address fails when user configures a duplicate mac address that matches that of another vNIC on the same port. The bna does not handle the ucast failure and keeps this address in cache. On disable of the vNIC, bna tries to delete the failed base mac address and the fw asserts. On failure of ucast address, mark ucast address set to false. Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S. Miller <davem@davemloft.net>
| * | bna: Clear Driver Config Flags When HW ResetsRasesh Mody2013-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Driver configuration flags are retained across open/stop operations preventing configurations to be set in next open/stop. Setting MTU on a 1020 causes network to fail until a reboot is performed on the host. Clear the flags when configuration resets in hardware.

* bna: add missing iounmap() on error in bnad_init()Wei Yongjun2013-05-13
| | | | | | | | | | Add the missing iounmap() before return from bnad_init() in the error handling case. Introduced by commit 01b54b1451853593739816a392485c4e2bee7dda (bna: tx rx cleanup fix).

* net: vlan: add protocol argument to packet tagging functionsPatrick McHardy2013-04-19
| | | | | | | | | | Add a protocol argument to the VLAN packet tagging functions. In case of HW tagging, we need that protocol available in the ndo_start_xmit functions, so it is stored in a new field in the skb. The new field fits into a hole (on 64 bit) and doesn't increase the sks's size. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | Change the rx_{add,kill}_vid callbacks to take a protocol argument in preparation of 802.1ad support. The protocol argument used so far is always htons(ETH_P_8021Q). Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: vlan: rename NETIF_F_HW_VLAN_* feature flags to NETIF_F_HW_VLAN_CTAG_*Patrick McHardy2013-04-19
| | | | | | | | | | Rename the hardware VLAN acceleration features to include "CTAG" to indicate that they only support CTAGs. Follow up patches will introduce 802.1ad server provider tagging (STAGs) and require the distinction for hardware not supporting acclerating both.

* bna: Firmware updateRasesh Mody2012-12-11
| | | | | | | | | | | | | | | Change Details: - Added Stats clear counter to the bfi_enet_stats_mac structure and ethtool stats - Modified the firmware naming convention to contain the firmware image version (3.1.0.0). The new convention is <firmware-image>-<firmware-version>.bin The change will enforce loading only compatible firmware with this driver and also avoid over-writing the old firmware image in-order to load new version driver as the firmware names used to be the same.

* bna: Add RX StateRasesh Mody2012-12-11
| | | | | | | | | | | | | | | | | | Change Details: - BNA state machine for Rx in start_wait state moves it to stop_wait on receipt of RX_E_STOP. In Rx stop_wait state, on receipt of RX_E_STARTED event does enet stop RX_E_STOPPED event does rx_cleanup_cbfn rx_cleanup_cbfn in this case is called without post_cbfn. post_cbfn happens only after RX_E_STARTED event is received in start_wait. Without doing post_cbfn, NAPI remains disabled and in cleanup we try to disable again causing endless wait. ifconfig process and other workers can thus get stuck. - Introducing start_stop_wait state for Rx. This state handles the case of if post_cbfn is not done simply do stop without the cleanup. Signed-off-by: Rasesh Mody <rmody@brocade.com> Signed-off-by: David S. Miller <davem@davemloft.net>
