- tcp/scheme/tcp.rs: write_buf now returns the actual bytes from
send_slice() instead of buf.len(). Fixes TCP silent data truncation
when the send buffer cannot accept the full request.
- netstack/scheme/ip.rs: fpath() uses .expect() with a message in place
of .unwrap() for clearer diagnostics on buffer write failure.
- dhcpd/main.rs: parse the first non-flag positional argument as the
interface name. Previously dhcpd was hardcoded to 'eth0', which broke
when netctl spawned dhcpd with a different iface name.
- drivers/common/dma.rs: introduce Dma::sync_for_cpu() and
sync_for_device() that issue acquire/release fences. Provides a
portable API for DMA-buffer ordering without a hard dependency on
architecture-specific memory barriers.
- drivers/net/virtio-netd/scheme.rs: call sync_for_cpu() before reading
the VirtHeader in try_recv and sync_for_device() before queueing the
TX chain. Eliminates the risk of reading partially-written DMA
contents on architectures where the device and CPU do not share a
coherent cache.
The Warn console level correlated with a deterministic login-auth
regression in the mini image (login reads the username but never reaches
MOTD/spawn_shell; 0/3 boots authenticated vs 1/1 with Info). Restore
Info-level console output while the interaction is re-verified; console
spam will be reduced later via a safer mechanism (routing daemon output,
not lowering the shared log level).
Daemons log via OutputBuilder::stderr() at output_level, which shares the
interactive console/login VT. At Info they spam routine chatter (cpufreqd,
thermald, i2c-hidd, ...) over the login prompt as boot continues in
parallel with getty. Drop the console filter to Warn; full Info logs are
still written to per-daemon log files (file_level), and a bootloader env
var can raise it for debugging.
Per local/docs/PATCH-PRESERVATION-AUDIT-2026-07-12.md the base
fork was carrying only 38 of 100 patches in local/patches/base/.
The other 62 patches' content was silently missing from the fork
working tree, even though their .patch files were preserved.
This commit re-applies 41 patches that genuinely still apply
cleanly + 17 hunks that partially applied. Recovery covers:
- D-Bus initfs service wiring (P4-initfs-dbus-services)
- USB service wiring (P4-initfs-usb-drm-services)
- netcfg/dhcp/dhcpv6 driver fixes
- acpid shutdown/PM/quirk fixes
- inputd/ps2d hard-fail logging
- pcid driver interface refinements (server cmd channel)
- virtio-core for VirtualBox support
- ixgbed/rtl8139/rtl8168 net drivers
- ahcid NCQ + per-function interrupt coalescing
- logd persistent logging
- bootstrap procmgr race-condition fixes
- cargo version pin to +rb0.3.0 (synchronized release branch)
58 files changed, +1444/-318 lines.
Untracked mnt/ tree and *.orig / *.rej files cleaned up after
patch application (leftover from absolute-path patch headers).
This way PCI drivers don't need to use the privileged physmap interface,
but only need access to a pcid handle. This is not yet enough for
running drivers as unprivileged processes. Interrupts also need
privileges and we need IOMMU support in the kernel.
