usbnet: Fix tx_bytes statistic running backward in cdc_ncm

2015-03-29T19:06:45Z

cdc_ncm disagrees with usbnet about how much framing overhead should be counted in the tx_bytes statistics, and tries 'fix' this by decrementing tx_bytes on the transmit path. But statistics must never be decremented except due to roll-over; this will thoroughly confuse user-space. Also, tx_bytes is only incremented by usbnet in the completion path. Fix this by requiring drivers that set FLAG_MULTI_FRAME to set a tx_bytes delta along with the tx_packets count.

usbnet: Fix tx_packets stat for FLAG_MULTI_FRAME drivers

2015-03-29T19:06:43Z

Currently the usbnet core does not update the tx_packets statistic for drivers with FLAG_MULTI_PACKET and there is no hook in the TX completion path where they could do this. cdc_ncm and dependent drivers are bumping tx_packets stat on the transmit path while asix and sr9800 aren't updating it at all. Add a packet count in struct skb_data so these drivers can fill it in, initialise it to 1 for other drivers, and add the packet count to the tx_packets statistic on completion.

cx82310_eth: wait for firmware to become ready

2015-03-21T22:23:19Z

When the device is powered up, some (older) firmware versions fail to work properly if we send commands before the boot is complete (everything is OK when the device is hot-plugged). The firmware indicates its ready status by putting the link up. Newer firmwares delay the first command so they don't suffer from this problem. They also report the link being always up. Wait for firmware to become ready (link up) before sending any commands and/or data. This also allows lowering CMD_TIMEOUT value to a reasonable time. Tested with 4.1.0.9 (old) and 4.1.0.30 (new) firmware versions. Signed-off-by: Ondrej Zary Signed-off-by: David S. Miller

Revert "net: cx82310_eth: use common match macro"

2015-03-19T02:37:38Z

This reverts commit 11ad714b98f6d9ca0067568442afe3e70eb94845 because it breaks cx82310_eth. The custom USB_DEVICE_CLASS macro matches bDeviceClass, bDeviceSubClass and bDeviceProtocol but the common USB_DEVICE_AND_INTERFACE_INFO matches bInterfaceClass, bInterfaceSubClass and bInterfaceProtocol instead, which are not specified.

Pull networking fixes from David Miller: 1) If an IPVS tunnel is created with a mixed-family destination address, it cannot be removed. Fix from Alexey Andriyanov. 2) Fix module refcount underflow in netfilter's nft_compat, from Pablo Neira Ayuso. 3) Generic statistics infrastructure can reference variables sitting on a released function stack, therefore use dynamic allocation always. Fix from Ignacy Gawędzki. 4) skb_copy_bits() return value test is inverted in ip_check_defrag(). 5) Fix network namespace exit in openvswitch, we have to release all of the per-net vports. From Pravin B Shelar. 6) Fix signedness bug in CAIF's cfpkt_iterate(), from Dan Carpenter. 7) Fix rhashtable grow/shrink behavior, only expand during inserts and shrink during deletes. From Daniel Borkmann. 8) Netdevice names with semicolons should never be allowed, because they serve as a separator. From Matthew Thode. 9) Use {,__}set_current_state() where appropriate, from Fabian Frederick. 10) Revert byte queue limits support in r8169 driver, it's causing regressions we can't figure out. 11) tcp_should_expand_sndbuf() erroneously uses tp->packets_out to measure packets in flight, properly use tcp_packets_in_flight() instead. From Neal Cardwell. 12) Fix accidental removal of support for bluetooth in CSR based Intel wireless cards. From Marcel Holtmann. 13) We accidently added a behavioral change between native and compat tasks, wrt testing the MSG_CMSG_COMPAT bit. Just ignore it if the user happened to set it in a native binary as that was always the behavior we had. From Catalin Marinas. 14) Check genlmsg_unicast() return valud in hwsim netlink tx frame handling, from Bob Copeland. 15) Fix stale ->radar_required setting in mac80211 that can prevent starting new scans, from Eliad Peller. 16) Fix memory leak in nl80211 monitor, from Johannes Berg. 17) Fix race in TX index handling in xen-netback, from David Vrabel. 18) Don't enable interrupts in amx-xgbe driver until all software et al. state is ready for the interrupt handler to run. From Thomas Lendacky. 19) Add missing netlink_ns_capable() checks to rtnl_newlink(), from Eric W Biederman. 20) The amount of header space needed in macvtap was not calculated properly, fix it otherwise we splat past the beginning of the packet. From Eric Dumazet. 21) Fix bcmgenet TCP TX perf regression, from Jaedon Shin. 22) Don't raw initialize or mod timers, use setup_timer() and mod_timer() instead. From Vaishali Thakkar. 23) Fix software maintained statistics in bcmgenet and systemport drivers, from Florian Fainelli. 24) DMA descriptor updates in sh_eth need proper memory barriers, from Ben Hutchings. 25) Don't do UDP Fragmentation Offload on RAW sockets, from Michal Kubecek. 26) Openvswitch's non-masked set actions aren't constructed properly into netlink messages, fix from Joe Stringer. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: (116 commits) openvswitch: Fix serialization of non-masked set actions. gianfar: Reduce logging noise seen due to phy polling if link is down ibmveth: Add function to enable live MAC address changes net: bridge: add compile-time assert for cb struct size udp: only allow UFO for packets from SOCK_DGRAM sockets sh_eth: Really fix padding of short frames on TX Revert "sh_eth: Enable Rx descriptor word 0 shift for r8a7790" sh_eth: Fix RX recovery on R-Car in case of RX ring underrun sh_eth: Ensure proper ordering of descriptor active bit write/read net/mlx4_en: Disbale GRO for incoming loopback/selftest packets net/mlx4_core: Fix wrong mask and error flow for the update-qp command net: systemport: fix software maintained statistics net: bcmgenet: fix software maintained statistics rxrpc: don't multiply with HZ twice rxrpc: terminate retrans loop when sending of skb fails net/hsr: Fix NULL pointer dereference and refcnt bugs when deleting a HSR interface. net: pasemi: Use setup_timer and mod_timer net: stmmac: Use setup_timer and mod_timer net: 8390: axnet_cs: Use setup_timer and mod_timer net: 8390: pcnet_cs: Use setup_timer and mod_timer ...
