uml: vector: Remove unused definitions VECTOR_{WRITE,HEADERS}

2023-02-13T09:14:32+00:00

Remove definitions of VECTOR_WRITE and VECTOR_HEADERS since no longer used. Signed-off-by: Carlos Bilbao Acked-By: Anton Ivanov Signed-off-by: Richard Weinberger

uml: net: vector: fix const issue

2022-03-11T09:47:05+00:00

Since the constification of MAC addresses, the argument to uml_vector_default_bpf() must be const. Signed-off-by: Johannes Berg Acked-By: anton ivanov Signed-off-by: Richard Weinberger

um: Fix typo in vector driver transport option definition

2020-04-29T19:22:15+00:00

No big problem as "raw" and "gre" have the same length, but could go wrong if they don't in the future. Signed-off-by: Ignat Korchagin Signed-off-by: Richard Weinberger

um: Loadable BPF "Firmware" for vector drivers

2019-11-25T21:43:31+00:00

All vector drivers now allow a BPF program to be loaded and associated with the RX socket in the host kernel. 1. The program can be loaded as an extra kernel command line option to any of the vector drivers. 2. The program can also be loaded as "firmware", using the ethtool flash option. It is possible to turn this facility on or off using a command line option. A simplistic wrapper for generating the BPF firmware for the raw socket driver out of a tcpdump/libpcap filter expression can be found at: https://github.com/kot-begemot-uk/uml_vector_utilities/ Signed-off-by: Anton Ivanov Signed-off-by: Richard Weinberger

um: Add SPDX headers for files in arch/um/drivers

2019-09-15T19:37:16+00:00

Convert files to use SPDX header. All files are licensed under the GPLv2. Signed-off-by: Alex Dewar Signed-off-by: Richard Weinberger

um: Added support for unix socket transports and bess transport

2019-09-15T19:37:09+00:00

This adds support for the UNIX domain socket transports in general and implements a Netsys::BESS compatible transport interface. For details on Netsys::BESS see https://github.com/NetSys/bess Signed-off-by: Anton Ivanov Signed-off-by: Richard Weinberger

um: Add legacy tap support and rename existing vector to hybrid

2019-09-15T19:37:08+00:00

1. Adds legacy tap support 2. Renames tap+raw as hybrid Signed-off-by: Anton Ivanov Signed-off-by: Richard Weinberger

Fix vector raw inintialization logic

2018-03-29T20:18:02+00:00

Vector RAW in UML needs to BPF filter its own MAC only if QDISC_BYPASS has failed. If QDISC_BYPASS is successful, the frames originated locally are not visible to readers on the raw socket. Signed-off-by: Anton Ivanov Signed-off-by: Richard Weinberger

High Performance UML Vector Network Driver

2018-02-19T18:38:51+00:00

1. Provides infrastructure for vector IO using recvmmsg/sendmmsg. 1.1. Multi-message read. 1.2. Multi-message write. 1.3. Optimized queue support for multi-packet enqueue/dequeue. 1.4. BQL/DQL support. 2. Implements transports for several transports as well support for direct wiring of PWEs to NIC. Allows direct connection of VMs to host, other VMs and network devices with no switch in use. 2.1. Raw socket >4 times higher PPS and 10 times higher tcp RX than existing pcap based transport (> 4Gbit) 2.2. New tap transport using socket RX and tap xmit. Similar performance improvements (>4Gbit) 2.3. GRE transport - direct wiring to GRE PWE 2.4. L2TPv3 transport - direct wiring to L2TPv3 PWE 3. Tuning, performance and offload related setting support via ethtool. 4. Initial BPF support - used in tap/raw to avoid software looping 5. Scatter Gather support. 6. VNET and checksum offload support for raw socket transport. 7. TSO/GSO support where applicable or available 8. Migrates all error messages to netdevice_*() and rate limits them where needed.
