Package: vlan Version: 2.0.5+nmu3 Followup-For: Bug #456309 Hi,
I have an alternative implementation for the freeform-vlan-interface-name feature suggested by Michael Gebetsroither in 2008. His documentation patch (https://bugs.debian.org/cgi-bin/bugreport.cgi?att=2;bug=456309;filename=0002-Add-documentation-to-manpage-for-free-named-vlan-int.patch;msg=20) also covers this implementation. Basically, if in `iface IFACE inet ...`, you specify "vlan-raw-interface" AND "vlan-id", IFACE can be any valid Linux interface name and doesn't have to follow a specific naming convention. The following minimalistic patch adds this feature: --- a/vlan 2026-04-06 12:19:20.417752254 +0200 +++ b/vlan 2026-04-06 12:29:28.398940902 +0200 @@ -51,10 +51,15 @@ mkdir -p "$STATEDIR" && echo "DEV_PLUS_VID_NO_PAD" > "$STATEDIR/name-type" VLANID=`echo $IFACE|sed "s/[^.]*\.0*//g"` ;; - *) + # Interfaces whose name doesn't follow a specific naming convention can still be created if both raw-device and vlan ID are specified + if [ -n "$IF_VLAN_ID" -a -n "$IF_VLAN_RAW_DEVICE" ]; then + VLANID="$IF_VLAN_ID" + else exit 0 + fi ;; + esac if [ -n "$IF_MTU" -a -n "$IF_VLAN_RAW_DEVICE" ]; then @@ -73,7 +78,11 @@ if [ ! -e "/sys/class/net/$IFACE" ]; then ip link set up dev $IF_VLAN_RAW_DEVICE #vconfig add $IF_VLAN_RAW_DEVICE $VLANID + if [ -n "$IF_VLAN_ID" ]; then + NAME_TYPE=FREEFORM + else NAME_TYPE=DEV_PLUS_VID_NO_PAD + fi [ -r "$STATEDIR/name-type" ] && NAME_TYPE=$(cat "$STATEDIR/name-type") case "$NAME_TYPE" in VLAN_PLUS_VID) @@ -88,6 +97,9 @@ DEV_PLUS_VID_NO_PAD) NAME="$IF_VLAN_RAW_DEVICE.$VLANID" ;; + FREEFORM) + NAME="$IFACE" + ;; esac ip link add link "$IF_VLAN_RAW_DEVICE" name "$NAME" \ type vlan id "$VLANID" András Ps. (Incidentally, there seems to be no reason for the STATEDIR/name-type file; you could just set the NAME_TYPE variable directly.) -- System Information: Debian Release: forky/sid APT prefers stable-security APT policy: (500, 'stable-security'), (350, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 6.19.10+deb14-amd64 (SMP w/8 CPU threads; PREEMPT) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=C.UTF-8, LC_CTYPE=hu_HU.UTF-8 (charmap=UTF-8), LANGUAGE=en_US.UTF-8 Shell: /bin/sh linked to /usr/bin/dash Init: runit (via /run/runit.stopit) LSM: AppArmor: enabled Versions of packages vlan depends on: ii iproute2 6.19.0-1 vlan recommends no packages. vlan suggests no packages. -- Configuration Files: /etc/network/if-pre-up.d/vlan changed [not included] -- no debconf information -- Energizer Bunny arrested.
