2015-10-16drivers/net: get rid of unnecessary initializations in .get_drvinfo()Ivan Vecera1-2/+0
Many drivers initialize uselessly n_priv_flags, n_stats, testinfo_len, eedump_len & regdump_len fields in their .get_drvinfo() ethtool op. It's not necessary as these fields is filled in ethtool_get_drvinfo(). v2: removed unused variable v3: removed another unused variable Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S.

2015-05-27net: netxen: correct sysfs bin attribute return codeVladimir Zapolskiy1-3/+3
If read() syscall requests unexpected number of bytes from "dimm" binary attribute file, return EINVAL instead of EPERM. At the same time pin down sysfs file size to the fixed sizeof(struct netxen_dimm_cfg), which allows to exploit some missing sanity checks from kernfs (file boundary checks vs offset etc.) Signed-off-by: Vladimir Zapolskiy <vz@mleia.com> Signed-off-by: David S.

2015-05-09netxen_nic: use spin_[un]lock_bh around tx_clean_lock (2)Tony Camuso1-2/+2
This patch should have been part of the previous patch having the same summary. See http://marc.info/?l=linux-kernel&m=143039470103795&w=2 Unfortunately, I didn't check to see where else this lock was used before submitting that patch. This should take care of it for netxen_nic, as I did a thorough search this time. To recap from the original patch; although testing this driver with DEBUG_LOCKDEP and DEBUG_SPINLOCK enabled did not produce any traces, it would be more prudent in the case of tx_clean_lock to use _bh versions of spin_[un]lock, since this lock is manipulated in both the process and softirq contexts. This patch was tested for functionality and regressions with netperf and DEBUG_LOCKDEP and DEBUG_SPINLOCK enabled.

Pull networking updates from David Miller: "Most notable changes in here: 1) By far the biggest accomplishment, thanks to a large range of contributors, is the addition of multi-send for transmit. This is the result of discussions back in Chicago, and the hard work of several individuals. Now, when the ->ndo_start_xmit() method of a driver sees skb->xmit_more as true, it can choose to defer the doorbell telling the driver to start processing the new TX queue entires. skb->xmit_more means that the generic networking is guaranteed to call the driver immediately with another SKB to send. There is logic added to the qdisc layer to dequeue multiple packets at a time, and the handling mis-predicted offloads in software is now done with no locks held. Finally, pktgen is extended to have a "burst" parameter that can be used to test a multi-send implementation. Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4, virtio_net Adding support is almost trivial, so export more drivers to support this optimization soon. I want to thank, in no particular or implied order, Jesper Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann, David Tat, Hannes Frederic Sowa, and Rusty Russell. 2) PTP and timestamping support in bnx2x, from Michal Kalderon. 3) Allow adjusting the rx_copybreak threshold for a driver via ethtool, and add rx_copybreak support to enic driver. From Govindarajulu Varadarajan. 4) Significant enhancements to the generic PHY layer and the bcm7xxx driver in particular (EEE support, auto power down, etc.) from Florian Fainelli. 5) Allow raw buffers to be used for flow dissection, allowing drivers to determine the optimal "linear pull" size for devices that DMA into pools of pages. The objective is to get exactly the necessary amount of headers into the linear SKB area pre-pulled, but no more. The new interface drivers use is eth_get_headlen(). From WANG Cong, with driver conversions (several had their own by-hand duplicated implementations) by Alexander Duyck and Eric Dumazet. 6) Support checksumming more smoothly and efficiently for encapsulations, and add "foo over UDP" facility. From Tom Herbert. 7) Add Broadcom SF2 switch driver to DSA layer, from Florian Fainelli. 8) eBPF now can load programs via a system call and has an extensive testsuite. Alexei Starovoitov and Daniel Borkmann. 9) Major overhaul of the packet scheduler to use RCU in several major areas such as the classifiers and rate estimators. From John Fastabend. 10) Add driver for Intel FM10000 Ethernet Switch, from Alexander Duyck. 11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric Dumazet. 12) Add Datacenter TCP congestion control algorithm support, From Florian Westphal. 13) Reorganize sk_buff so that __copy_skb_header() is significantly faster.

2013-03-15netxen: write IP address to firmware when using bondingnikolay@redhat.com2-78/+147
This patch allows LRO aggregation on bonded devices that contain an NX3031 device. It also adds a for_each_netdev_in_bond_rcu(bond, slave) macro which executes for each slave that has bond as master. V3: After testing and discussing this with Rajesh, I decided to keep the vlan ip cache and just rename it to ip_cache since it will store bond ip addresses too. A new master flag has been added to the ip cache to denote that the address has been added because of a master device. I've taken care of the enslave/release cases by checking for various combinations of events and flags (e.g. netxen has a master, it's a bond master and it's not marked as a slave means it is being enslaved and is dev_open()ed in bond_enslave). I've changed netxen_free_ip_list() to have a "master" parameter which causes all IP addresses marked as master to be deleted (used when a netxen is being released). I've made the patch use the new upper device API as well. The following cases were tested: - bond -> netxen - vlan -> netxen - vlan -> bond -> netxen V2: Remove local ip caching, retrieve addresses dynamically and restore them if necessary.

commits 9d11bd159 ("wimax: Remove unnecessary alloc/OOM messages, alloc cleanups") and b2adaca92 ("ethernet: Remove unnecessary alloc/OOM messages, alloc cleanups") added a couple of unused variable warnings. Remove the now unused variables. Noticed-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2013-02-04ethernet: Remove unnecessary alloc/OOM messages, alloc cleanupsJoe Perches4-38/+17
alloc failures already get standardized OOM messages and a dump_stack. Convert kzalloc's with multiplies to kcalloc. Convert kmalloc's with multiplies to kmalloc_array. Fix a few whitespace defects. Convert a constant 6 to ETH_ALEN. Use parentheses around sizeof. Convert vmalloc/memset to vzalloc. Remove now unused size variables.

2013-01-22netxen: fix off by one bug in netxen_release_tx_buffer()Eric Dumazet2-1/+3
Christoph Paasch found netxen could trigger a BUG in its dismantle phase, in netxen_release_tx_buffer(), using full size TSO packets. cmd_buf->frag_count includes the skb->data part, so the loop must start at index 1 instead of 0, or else we can make an out of bound access to cmd_buff->frag_array[MAX_SKB_FRAGS + 2] Christoph provided the fixes in netxen_map_tx_skb() function. In case of a dma mapping error, its better to clear the dma fields so that we don't try to unmap them again in netxen_release_tx_buffer() Reported-by: Christoph Paasch <christoph.paasch@uclouvain.be> Signed-off-by: Eric Dumazet <edumazet@google.com> Tested-by: Christoph Paasch <christoph.paasch@uclouvain.be> Cc: Sony Chacko <sony.chacko@qlogic.com> Cc: Rajesh Borundia <rajesh.borundia@qlogic.com> Signed-off-by: Christoph Paasch <christoph.paasch@uclouvain.be> Signed-off-by: David S.
