Before this, 26 tools hardcoded the literal "gopacket vX.Y.Z-beta -
Copyright 2026 Google LLC" banner in print statements, totaling 34
occurrences across the tree. Every version bump meant updating the
same string 34 times.
Switches every tool to call flags.Banner(), which builds the banner
from flags.Version. The Version const in pkg/flags/flags.go is now
the single source of truth; future version bumps are a one-line
change.
Mechanical split:
- 3 common print patterns (fmt.Println, fmt.Fprintln os.Stderr,
fmt.Fprintf with trailing \n\n) swept with sed.
- 6 heredoc-style flag.Usage functions had the banner line on a
backtick-quoted format string. Each was split into a separate
fmt.Fprintln(os.Stderr, flags.Banner()) followed by the existing
Fprintf with the banner line trimmed off the format string.
- 9 tools needed a new pkg/flags import added.
- tools/describeTicket already imports github.com/jcmturner/gokrb5
/v8/iana/flags for Kerberos flag constants, so pkg/flags is aliased
as gopflags there to avoid the name collision.
Verified: go build, go vet, and go test ./pkg/transport/ all clean
under default, CGO_ENABLED=0, and GOOS=windows CGO_ENABLED=0. Spot-
checked -h output on samrdump, rpcmap, mssqlinstance, ping, and
describeTicket; each renders the banner identically to before.
Fixes#6. The module was declared as `module gopacket` in go.mod,
which is not a canonical import path. External projects could not
`go get github.com/mandiant/gopacket` to use any of the 24
protocol packages as a library; the only workaround was to clone
the repo and add a `replace` directive to their own go.mod.
This commit:
- Sets `module github.com/mandiant/gopacket` in go.mod.
- Rewrites 434 import statements across 157 files from the bare
`gopacket/...` prefix to `github.com/mandiant/gopacket/...`.
Pure mechanical change, no behavior difference. Makes the README's
library story (pkg/ directory, 24 reusable packages) actually
usable from external code.
Bumps the version string across pkg/flags and all tool banners to
v0.1.1-beta. Marks the first feature release after the initial beta
(adds the -proxy socks flag and UDP-under-proxy guard landing in
this PR).
Note: the version string is currently duplicated 34 times across 27
tool binaries and flags.go. A follow-up PR should refactor every
tool to call flags.Banner() instead of hardcoding the literal, so
future bumps are one-line changes.
