initramfs-tools (0.150ubuntu2) questing; urgency=medium
* Revert making 3cpio the default cpio tool since it is too late for the
questing release cycle.
initramfs-tools (0.150ubuntu1) questing; urgency=medium
* Merge with Debian unstable. Remaining changes:
- Use 3cpio for unmkinitramfs/lsinitramfs if available (for massive speedup)
and let initramfs-tools-core suggest 3cpio
- Harmonize kernel module installation with dracut's behavior:
- Do not install ARM/RISCV specific modules on other architectures.
- Revert "autopkgtest: Fix test failure when built-in drivers request
firmware". This workaround is not needed on Ubuntu.
- support mounting of loopback devices via loop*= parameters
- Add vfat and nls modules to the initramfs.
- Drop hooks/keymap, scripts/init-top/keymap, and associated code;
console-setup takes care of this in Ubuntu.
- Allow scripts and hooks to specify OPTION=VAR, and unless VAR is set to
something other than "n", the script will not be included.
- Add a new wait-for-root binary to the initramfs-tools-bin package that
uses libudev to wait for udev to create the udev device, or wait for
udev to finish processing if we catch it in the act, and returns the
filesystem type as already probed by udev.
- Automatically blacklist vga16fb when vga= or video= specified on kernel
command-line.
- Add hwaddr= alias for BOOTIF= for compatibility.
- Set hostname at boot, for the benefit of mdadm autoassembly.
- Add Hyper-V paravirtualised device drivers to the initramfs to allow
booting of stock images in a Hyper-V guest.
- ppc64el: enable PowerPC NX Crypto Coprocessor
- Add support for uppercase and lowercase uuids.
- Make busybox-initramfs a real runtime dependency, fixing kernel install
failures with cryptsetup
- init: Don't interpret "rootdelay" as a static sleep.
- scripts/local: Let rootdelay determine the wait-for-root timeout.
- Increase rootdelay to 180s on powerpc/ppc64/ppc64el
- Support roottimeout= as the authoritative name for rootdelay= since the
Ubuntu interpretation of rootdelay is *not* a delay and this causes
inconsistent behavior depending on whether the kernel or an initramfs is
interpreting it.
- Revised mountroot failure support. This is now deprecated and
effectively removed. However, to prevent breakage in other packages the
add_mountroot_fail_hook function is still present as an empty stub.
- Add a new 'fixrtc' script that tries to set the system clock forward
based on the last mount time of the root disk; without this kludge,
systems without a working RTC will end up in a perpetual reboot loop.
- Restore the framebuffer hook and script, copying KMS and other
framebuffer drivers into the initramfs, but make them optional; you need
to set FRAMEBUFFER=y for these to be included.
- netinfo_to_resolv_conf: Add support for IPv6
- resume: only resume when the partition contains a resume image
- Fix resuming a hibernate session from a swapfile
- scripts/functions: by default, when setting up networking, use dhclient
if we're asked to do DHCP explicitly, or if we otherwise are expected to
do things automatically.
- split out IPv6 options in its own cmdline parameter: ip6= ; always use
dhclient in this case if the value set is anything other than 'off' or
'none'. Furthermore, parse anything other than 'on', 'dhcp' or 'any' as
the name of an interface.
- rework the stop conditions so that we properly handle the ROUNDTTT loop,
timing out after a short period of time and trying again after a short
sleep.
- add a 'done' parameter for both ip= and ip6= so that we can properly
exit the ROUNDTTT loop once we know that either there is no work to do,
or that we've achieved what we wanted (that is, to bring up IPv4, IPv6,
or possibly both).
- Just let dhclient scan the interfaces if none is specified for IPv6.
(previously unnoted)
- Do not handle ip=rarp specially (ipconfig hasn't supported it for some
time)
- Call dhclient in simple cases for IPv4 (this makes some small observable
changes -- for example ip=bootp will now make a DHCP request too -- but
nothing that seems important).
- Do not let dhclient processes hang around past the pivot and have them
respect the shorter timeouts ipconfig was given.
- hook-functions, mkinitramfs, scripts/functions: support usage of dns
after configure_networking.
- Add unit tests for DNS support
- scripts/functions: write netplan config files to /run/netplan for
network devices configured with configure_networking.
- Adjust testsuite for correct expected netplan output.
- Add tests to parse netplan.yaml with netplan generate.
- scripts/functions: include a new option to skip enslaved network
devices.
- Auto activate qeth devices on s390x hosts, when using ip= ip6= command
lines.
- Add support for creating VLANs via vlan=eth0.1:eth0 on kernel
commandline, and as VLAN= conf.d snippet.
- Emit empty dictionary in the ethernets section, for static vlan configs
without any matches, as otherwise it is invalid config.
- Skip attempting to chzdev enable VLAN device
- Work out the kernel modules required to support ZFS filesystems and add
them as necessary.
- Add modules for nvme path components on multipath nvme.
- Drop usage of klibc-utils' fstype in favor of always using udev blkid.
- Use set -a/+a around loading conf snippets, to autoexport hook
configuration variables. This thus allows packaged hooks to configure
each other.
- Fix PATH to include /usr/local.
- Fix resume failure due to resume=UUID=... in certain cases
- Always mount loop-mount filesystems read-write; ntfs-3g and vfat can't
remount yet.
- Provide a clearer error on mount failure of the Windows host filesystem
- scripts/local: Re-execute cryptroot local-block script.
- Force copy pthread and libgcc_s libraries via a stub binary. To avoid
circular shared library dependencies between compiler and libc,
libpthreads chooses to dlopen libgcc_s, instead of linking against it.
However, we have no way to parse/know what it needs. And even when we
hardcode to include libgcc_s1, we don't have a way to know which
libgcc_s1 is needed on a given system and from which path to include it.
But there is a hook-function to copy a binary and all of its shared
library dependencies. Thus create a stub empty executable, with shared
linking against pthreads and gcc_s1 and always include it in the initrd.
This way at initrd creation time, ldd is used to correctly resolve these
shared library dependencies and correctly copy them into the initrd.
This removes hardcoding paths as to where these libraries must be copied
from on the host.
- Lower the compression levels for zstd and lz4 Following the discussion
on the mailing list, we have reached a conclusion to lower the default
compression levels:
- For lz4, the compression level is lowered to 2 from 9
- For zstd, the compression level is lowered to 1 from 9
- Include dax and nfit modules, also needed for pmem devices.
- Add char/hw_random drivers
- Reinstate build-time shellcheck (but leave shellcheck out of
autopkgtests as per debian bug #992798)
- Bring up networking if ip6 is specified on cmdline.
- Add qemu-net-dnsmasq autopkgtest to test DHCPv6
- test: Ignore remaining systemd-udevd processes
- Replace dhclient by dhcpcd
- scripts/functions: do not fail to configure networking too quickly. In
particular make sure an unsuccessful attempt to run DHCP takes at least
$ROUNDTTT seconds.
- Install intel_lpss_pci and spi_pxa2xx_platform kernel modules for keyboard
on MacBook Pro 2017
- Install surface_aggregator_registry for keyboard on Surface Laptop 4
- Restore nvdimm and dax pmem-related modules
- configure_networking:
- Increase minimum timeout to 30 seconds
- Fix configuring BOOTIF when using iSCSI
- Set interface MTU if provided by the DHCP server
- autopkgtest: Test hostname already set in initrd
- resume: always write valid resume device to /sys/power/resume
- persist hostname provided by DHCP only if not set yet
- configure_networking: Configure IPv4 or IPv6 based on iBFT IP address
- test: skip failing qemu-net-iscsi on arm64
- Add iBFT test cases to qemu-net-iscsi autopkgtest
- scripts/functions: gateway4/gateway6 are depreated in netplan config,
generate routes instead
- autopkgtest: Ignore unmkinitramfs warning on stderr to work around
regression https://bugs.debian.org/1107592
- Let linux-firmware updates trigger the initramfs-tools autopkgtest
