meta-google: gbmc-bridge: Gate primary IP persistence on gbmc_rwfs_purge_done

2026-09-27T00:33:53+00:00

Only persist the primary bridge IP to /var/google/gbmc-br-ip if gbmc_rwfs_purge_done succeeds. If an RWFS purge is pending for the active trip ID or has not yet completed, attempting to write the IP to RWFS can fail due to ENOSPC or corrupt flash, or store state that will be immediately wiped on the pending reboot.

meta-google: gbmc-bridge: Check run initramfs for trip ID in gbmc_rwfs_purge_done

2026-09-27T00:33:52+00:00

When verifying whether the RWFS purge has completed for a given GBMC_TRIP_ID, also check /run/initramfs/rwfs-purged. Initramfs and clean-rwfs write the purge flag/trip ID to /run/initramfs/rwfs-purged during early boot purge handling. Checking both paths allows gbmc_rwfs_purge_done to recognize a completed purge even if the persistent /var overlay is not mounted or if running in tmpfs fallback mode.

meta-google: gbmc-bridge: Remount RWFS read-only before status update and reboot

2026-09-25T01:06:08+00:00

Call gbmc_br_dhcp_rwfs_sync_ro prior to requesting powercycle in 50-gbmc-psu-hardreset.sh.in and prior to reboot -f in 51-gbmc-reboot.sh to ensure filesystems are flushed and clean before the reset occurs.

meta-google: gbmc-bridge: Decouple early IP set from RWFS and persist on completion

2026-09-25T01:06:08+00:00

Avoid writing /var/google/gbmc-br-ip during the initial DHCP bound phase to prevent ENOSPC failures when RWFS is full. Persist the primary IP to RWFS via gbmc_net_unmask_and_write once all dhcp step hooks and RWFS purge have run. Change-Id: Icaf470d8e92970337ebc4e9d249e8d8a953454ae Signed-off-by: William A.

meta-google: gbmc-bridge: Add gbmc_rwfs_purge_done helper

2026-09-25T01:06:08+00:00

Add gbmc_fetch_trip_id and gbmc_rwfs_purge_done to gbmc-br-dhcp-lib.sh to parse the netboot trip ID into a global variable GBMC_TRIP_ID and verify against /var/google/rwfs-purged (or /run/initramfs/rwfs-purged when trip ID is absent).

meta-google: gbmc-bridge: Add gbmc-br-dhcp-lib with RWFS remount helper

2026-09-25T01:06:08+00:00

Add gbmc-br-dhcp-lib.sh to host DHCP netboot helpers for RWFS management: - gbmc_br_dhcp_rwfs_sync_ro: flushes pending writes and remounts / and the underlying RWFS read-only prior to reset or powercycle. Change-Id: I3e27d437c04f3f5cb140c188be7230b3ced0125c Signed-off-by: William A. Kennington III

meta-google: gbmc-net: Add gbmc_net_unmask_and_write helper

2026-09-25T01:06:08+00:00

Add gbmc_net_unmask_and_write to gbmc-net-lib.sh to safely unmask any bind-mounts over a persistent target file, touch the file to verify write capability, and write content to RWFS. Use gbmc_net_unmask_and_write in gbmc_br_set_ip to replace inline unmount and file creation logic. Change-Id: I9b0263595fe80c1cccfa34ac239b505793bb5224 Signed-off-by: William A. Kennington III

meta-google: gbmc-net: Specify proto static on dynamic routing policy rules

2026-09-25T01:06:08+00:00

When systemd-networkd reloads or reconfigures an interface, it parses RoutingPolicyRule entries and installs them into the kernel with protocol 'static'. When out-of-band scripts configure the same rules without proto static, the kernel treats them as distinct rules and creates duplicate entries. Specify 'proto static' when adding IPv6 routing policy rules in gbmc-nic-neigh and gbmc-ncsi-br-deprecated-ips to ensure rule deduplication and idempotence.

meta-google: gbmc-systemd-config: Disable networkd foreign routing policy management

2026-09-25T01:06:08+00:00

Set ManageForeignRoutingPolicyRules=no in networkd.conf to prevent systemd-networkd from dropping routing policy rules managed out-of-band by iproute2 when interfaces are reconfigured. Change-Id: I226b9f71c35a6435cfa69f36f332306263889154 Signed-off-by: William A. Kennington III

meta-google: gbmc-bridge: Report failure when dhcp-term stops DHCP

2026-09-25T01:06:08+00:00

When gbmc-br-dhcp-term stops DHCP after the 10-minute wait without /run/netboot_done being present, emit update_netboot_status "netboot" "DHCP is not running" "FAIL" so dhcp-done (port 23) and gbmc-netboot report an explicit failure instead of remaining at "Waiting on dhcp process". Break rather than exiting early if the DHCP slice is already inactive, and stop gbmc-br-dhcp@'*' synchronously before writing the final status.
