Bug ID: 1465
Summary: rte_bpf_load() hangs with six IPv6 addresses in the
filter causing dumpcap to fail
Product: DPDK
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: other
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Original thread on the users list (with all the dumpcap related details):
https://mails.dpdk.org/archives/users/2024-June/007702.html
Example filter causing the problem:
"host 1::1 or host 1::1 or host 1::1 or host 1::1 or host 1::1 or host 1::1"
The simplest way to reproduce is by using the test-suite, by adding the filter above to the 'sample_filters' in 'test_bpf.c' and invoke the test:
time sudo build/app/dpdk-test bpf_convert_autotest
This causes the test to take ~25 seconds instead of 2 seconds (btw, adding --log-level=lib.bpf:debug gives tons of output).
