[release-4.20] OCPBUGS-92083: ebpf: consolidate packet event logs into single line#723
Conversation
Previously, firewall packet events were logged as three separate syslog
messages (rule info, IP addresses, protocol details), making log parsing
and analysis more difficult. This change consolidates all packet event
information into a single log line for better observability.
Changes:
- Merge three separate eventsLogger.Info() calls into one
- Use strings.Builder and fmt.Fprintf for efficient log construction
- Use pipe separators (|) to delimit log sections visually
Example output format:
Before (3 lines):
ruleId 10 action Drop len 74 if br1
ipv4 src addr 192.xx.xx.149 dst addr 192.xx.xx.56
tcp srcPort 56354 dstPort 22
After (1 line):
ruleId 10 action Drop len 74 if br1 | ipv4 src 192.xx.xx.149 dst 192.xx.xx.56 | tcp srcPort 56354 dstPort 22
This improves log grep-ability, parsing, and integration with log
aggregation tools where single-line entries are preferred.

Update event parsing regex patterns in test/e2e/events/events.go to
match the new single-line log format with pipe delimiters.
Changes:
- Replace newline separators (\n) with pipe delimiters (\s\|\s)
- Remove 'addr' keyword from IP address fields
- Add IP version prefix matching (ipv4|ipv6)
- Use raw string literals (backticks) to avoid escaping backslashes
Old format (multi-line):
ruleId 10 action Drop len 98 if eth0
ipv4 src addr 172.20.0.1 dst addr 172.20.0.4
tcp srcPort 12345 dstPort 8080
New format (single line):
ruleId 10 action Drop len 98 if eth0 | ipv4 src 172.20.0.1 dst 172.20.0.4 | tcp srcPort 12345 dstPort 8080
