Reminder: the submission deadline is still open for only 6 days, please submit your proposals in time. This is a call for proposals for the BPF micro-conference at the Linux Plumbers Conference (LPC)

I am sending here as an RFC instead of LLVM's mailing list as I'm not sure this is the intended behavior, and the "fix" may therefore not be needed. Clang-compiled object files currently don't include

Hi. I need you advice. I have to write app to filter and LB ethernet traffic from 100G to 10x10G. What is better to use? eBPF XDP or DPDK?

Hi All, I am trying to collect IPFIX flow data from the linux host interface. Can someone guide me the best way to collect the data using XDP. Any samples for reference will be a great help. Thanks, S

The patch adds the test framework for OVS using afxdp. Currently there are two test cases, using ping and http as traffic forwarding through ovs with 2 afxdp netdev. Signed-off-by: William Tu <u901206

The patch creates a new netdev type "afxdp" and copies some of the afxdp api implementation from xdpsock_user.c at linux sample code. The afxdp ebpf programs/maps are loaded when dpif-netdev is create

AF_XDP requires attaching an xdp program and xskmap for each netdev. The patch provides these program/map and the loading and attaching implementation. Signed-off-by: William Tu <u9012063@...> --- aci

From: root <ovs-smartnic@...> The patch series introduces AF_XDP support for OVS netdev. AF_XDP is a new address family working together with eBPF. In short, a socket with AF_XDP family can receive an

hi, on RHEL7 we are facing timing issues in some bcc-tools scripts. The time subsystem might return backward timestamp via bpf_ktime_get_ns and thus screw up latency computation. This seems to be RHEL

While using ext4dist on RHEL7 we occasionally get following screwed up latencies: # ext4dist Tracing ext4 operation latency... Hit Ctrl-C to end. ^C operation = write usecs : count distribution 0 -> 1

While using xfsslower on RHEL7 we occasionally get following screwed up latencies: # xfsslower Tracing XFS operations slower than 1 ms TIME COMM PID T BYTES OFF_KB LAT(ms) FILENAME 13:25:03 git 3385 R
