It is only installed on RHEL 8+, but as noted in the first commit
that tried to do this - 0bb9a683 - we already have branches for
all RHEL releases, so there's no point keeping such a conditional
on the master branch. After 0bb9a683, 51-dracut-rescue-postinst.sh
was re-added because Fedora 30 needed it, with a FIXME saying to
remove it after F30 was released. But instead of that happening, it
got changed to a conditional to install it on Fedora <= 30 or RHEL
<= 8 in 9e68789d and the FIXME was removed, then in 9eb1d1ed that
conditional was simplified to only refer to RHEL, so we wound up
with this situation.
Note the last two commits were never ported to the RHEL-8 branch,
so it's broken, I will send a separate PR for that.

The underlying issues this was trying to solve is to get a cheap
workaround for the fact that (open)SUSE with atomic support moved
/etc stock files to /usr/etc in order to improve compatibility. But
now that even nsswitch.conf moved, this is no longer enough. And it
might be more trouble to support once it's in an official release.
So let's rather drop it now.
This reverts commit e0524af2bf.

Library file modules.d/99base/dracut-lib.sh contains initialization code
that makes sure certain directories and links are created when a system
runs from the produced initramfs. This file is normally sourced only
from initramfs scripts. However, modules.d/99base/module-setup.sh
includes it also when an initramfs image is being created to gain access
to some of the functions in this library. This can result in creating
unexpected directories and links on the current root file system when
the dracut command is executed.
For instance, during a system installation when dracut is invoked to
create an initial initramfs, the target sysroot might not contain
directory /run/initramfs but have /var/log. This situation results in
the code in modules.d/99base/dracut-lib.sh creating an unexpected link
/var/log/log that points to /run/initramfs/log. This link is then also
present on the installed system.
The patch fixes the problem by skipping the described logic in
modules.d/99base/dracut-lib.sh when the PREFIX variable is non-empty
which indicates that a target initramfs is being prepared. The variable
is set by modules.d/99base/module-setup.sh prior to including
dracut-lib.sh.

dracut builds today are fairly verbose to start, but on top of
that many of the messages tend to liberally use the
exclamation point `!` which calls attention to them.
I see these a lot when looking at rpm-ostree build logs
and it'd be nicer if we were quiet when there wasn't
an actual problem.
In this specific case, if the builder is explicitly adding
`--omit=foo`, there's no reason for us to say:
`dracut: dracut module 'foo' will not be installed, because it's in the list to be omitted!`
We already print the command line to start, so the information
is there.
Demote this message to debug.
Sometimes, systems have more elaborate backends in nsswitch.conf,
the complexity of which we do not want in the initrd. SUSE systems
with atomic for instance, where those files may also reside in /usr/etc.
With this change, the unavaiable nsswitch.conf backends will be silently
ignored, and we still end up with all the information we need.

This was added in https://github.com/systemd/systemd/pull/17149 and is
the designated cryptsetup target for all encrypted volumes that need to
be opened in the initrd.
So it effectively replaces `cryptsetup.target` and
`remote-cryptsetup.target` there. I've removed the latter since it was
added recently (by me) in #930, but kept `cryptsetup.target` since we've
been shipping it for a long time now.
With commit 3c8c807, /run/initramfs/isoscan and /run/initramfs/live
mountpoints are unmounted upon rd.live.ram boots. Save a link to
the iso-scan device in /run/initramfs/isoscandev to easily remount
the source, if desired.
This is a plain and simple hack around dependency issues between dracut
and systemd.
When using Tang-pinned LUKS root devices, we want to rely on
`systemd-cryptsetup@.service` to unlock it. However, that service only
runs `After=remote-fs-pre.target`, while `dracut-initqueue.service` has
`Before=remote-fs-pre.target` (which makes sense because we don't want
to attempt networked root devices before networking is up).
However, the rootfs-generator here wants to make sure that the root
device exists *before* exiting the initqueue via an initqueue/finished
"devexists" hook. This will never work though because by design
`systemd-cryptsetup@.service`, which unlocks the root device, won't run
until after we exit.
So we have a dependency cycle:
initqueue -> devexists hook -> root device ->
systemd-cryptsetup@.service -> remote-fs-pre.target -> initqueue
There's no clean way to break this. The root issue is that there's no
way right now to split sequencing of systemd services across the
initqueue/online and initqueue/finished events because it's all bundled
in a single service. (The deeper root issue of course is that we have
two init systems. :) ).
Here we do a tactical fix: if there's a `systemd-cryptsetup@.service`
instance, let's assume it's for the root device and skip waiting for it
to show up if it depends on `remote-fs-pre.target`.
dracut feeds whatever it receives in password field of
crypttab(5) to `cryptsetup -d`, treating them as plain-text key file.
Meanwhile, dracut treats the key file from `rd.luks.key` differently,
by have some special rules to decrypt those key files that has extension of
`gpg` and `img`.
Let's begin to treat them the same.
This is a backward-incompatible change for those people
that uses plain-text key-file that has extension of `gpg` and `img`.
However, those setup is questionable to begin with.
In the case of the s805x the drivers/hwmon directory contains the
scpi_hwmon kernel module.
On a running system, lsmod would output the following dependencies:
arm_scpi 24576 2 clk_scpi,scpi_hwmon
It means that if the clock driver is bundled in the initramfs it will
bring arm_scpi. But if scpi_hwmon is missing the scpi will be incomplete
and it can lead to crashes.
When the hwmon is bundled, no crash occurs

Some filesystem (e.g. ZFS, and btrfs subvolumes) don't use block
devices. Should they be mounted as `/`, `find_root_block_device`
yields nothing, hence dracut will append this problematic argument
to kernel cmdline:
root=/dev/block
On a machine that employ root ZFS on LUKS, which was setup with
an OpenPGP-encrypted key file, this argument renders that machine
unbootable. Remove that `root=/dev/block` manually could boot the
machine.
Let check if that device is a block device before write down `root`
argument. This is consistent with the check for block device in
`find_block_device`.

This was introduced with 6dafdda4a6, but
is actually caused by the fact that modules that have already been
installed cause dracut_install() to return without adding the module
to the hashmap. This can happen if an earlier-run dracut module chose
to install the same module. Now modprobe statements like:
softdep usb_storage post: uas
softdep uas pre: usb_storage
(which look weird, but are perfectly valid), cause
dracut_install() to enter an infinite recursion if and only if
at least one of the files has previously been installed by another
module.
Fix this by also adding already installed modules to the hashmap.
If there are any nonexistent libraries listed in /etc/ld.so.preload, ldd
prints error messages like:

This causes resolve_deps() to return error, which leads to symlinks
(like usr/bin/awk) not being copied into the initrd.

RebootWatchdogSec option that use watchdog to prevent reboot hangs. And

initramfs stage. So split the module installation to a standlone module.
Also when watchdog-module get included, install driver for all loaded

watchdog and watchdog-module return 255 in check(), so it's enabled only

systemd lets stdout go to journal only. Usually, this is desired
behavior to ensure that plymouth does not get disrupted.
However in the 01fips case, the system has to halt when the integrity
check fails to satisfy FIPS requirements. So the user will not be able
to inspect the journal.
As this is special to the fips module, we introduce a fips_info() which
works like info(), but deviates the output to stderr when running with
systemd.

After changing the kernel command line, the cmsifup script calls ifup

Most rpc services are not needed for NFSv4, so skip these components

Since commit ff70adf873ef ("initrd: save hostname to a file in /run"),
the initrd generator of NetworkManager parses the hostname from 'ip='
options of the kernel command line and writes it to
/run/NetworkManager/initrd/hostname.
When that file exists, set the kernel hostname.
In presence of multiple hostnames in the command line, the last one
wins. Hostnames from command line always have precedence over ones
received through DHCP. This is a bit different from the legacy network
module that gives higher precedence to the hostname (from DHCP or
command line) of the last interface that is brought up, which depends
on the udev order.

For the GRUB and zipl bootloaders the BLS fragment that is shipped by the

But there are cases where this BLS fragment is not suitable. For example,
if the boot directory is on a btrfs subvolume the path in the linux and
initrd fiels need to be adjusted with the real path. Otherwise GRUB won't
be able to read them.
The GRUB and zipl kernel-install plugins already take care of this before

the updated paths instead of using the BLS shipped by the kernel package.

/etc/vconsole.conf must be installed always, even in generic initrds, not only host-only ones.
systemd-vconsole-setup is run at initrd stage and expects either /etc/vconsole.conf or kernel cmdline options to exist.

But it is just a fallback. If /etc/vconsole.conf does not exist in initrd and if that patch is applied on systemd,
then the default consoel font is set despite the one being set in /etc/vconsole.conf and this setting is inherited
when new TTYs are opened. This leads to full ignorance of settings in /etc/vconsole.conf.
It is incorrect, and that is why this file must be copied to initrds always, but not only on host-only initrds.

According to POSIX.1-2017, 2.6.2 Parameter Expansion:
${parameter%[word]} [...] The word shall be expanded to produce a
pattern.
This means if word contains variables that itself contain special
characters like asterisks or backslashes, these are treated as pattern
characters unless the variable is quoted. Try e.g. the following example
in bash, dash or (busybox) ash:
i='a\c'; j='\'; echo "${i%$j*}"
This prints "a\c" because "$j*" is expanded to "\*", escaping the
asterisk. In contrast,
i='a\c'; j='\'; echo "${i%"$j"*}"
produces the expected result "a" because the backslash is not specially
treated any more after quoting.
The quotes that this commit adds have been previously removed in commit
f9c96cf56f, citing issues with busybox
hush without further specifying the actual error. I tested a recent
busybox build (upstream commit 9aa751b08ab03d6396f86c3df77937a19687981b)
and couldn't find any problems. Note that the above example always
produces "a\c" in hush regardless of quoting $j, making hush unsuitable
for use with dracut, but using quotes in parameter expansions generally
works.
The unquoted variables break the "rd.luks.uuid/name" kernel command line
options in dracut 050 because
str_replace "$luksname" '\' '\\'

dracut.sh already doesn't call fsfreeze if the output file is on
the root file system. For btrfs, however, this is not sufficient.
Because fsfreeze is a superblock operation, and all btrfs subvolumes
share the same superblock, fsfreeze may freeze the entire system
if the subvolume on which the output file is written and / are
subvolumes of the same file system. Avoid this by comparing file
system UUIDs for btrfs.

Detection of persistent memory devices works mostly out of the box
already. Only the "provider" modules for ndbus devices, which are responsible
to extract information of available NVDIMM devices and their configuration
from system firmware, are only indirectly linked into the module stack.
Examples for such modules are nfit.ko, nd_e820.ko, and virtio-pmem.ko.
Add a module that resolves these dependencies.
With GNU Make 4.3 on both ArchLinux, and VoidLinux,
GITVERION is always empty because of bad substitution.

but we don't need that complation.
We can merge DRACUT_MAIN_VERSION and GITVERSION into DRACUT_FULL_VERSION.

While we're at it, detect if we're in git worktree by:
limiting GIT_CEILING_DIRECTORIES to parent directory of
dracut's top level directory; instead of checking for .git directory,
in order to support git-worktree, in such case, .git will be a file, see

GitHub workflows fetch a clone of the dracut repository which doesn't
contain git tags, thus "breaking" the RPM build in certain situations
i.e.:
DRACUT_MAIN_VERSION in Makefile is defined as an output of `git describe`,
which in full git clone returns a tag with a numeric version. However,
without tags it returns SHA of the last commit, which later propagates into
`Provides:` attribute of the built RPM and can break dependency tree when
installed
`make rpm` usually chose `/tmp` as the `$rpmbuild` dir, which breaks the
dracut build, since it needs to execute `./configure`, but `/tmp` is
mounted with `-o noexec`, leading to:
```
/var/tmp/rpm-tmp.SwEhJO: line 46: ./configure: Permission denied
error: Bad exit status from /var/tmp/rpm-tmp.SwEhJO (%build)
RPM build errors:
Bad exit status from /var/tmp/rpm-tmp.SwEhJO (%build)
```
Switching to `/var/tmp` helps in this case.

Previously, we were doing `setup_net` from `ifup` for any setup that
wasn't DHCP, since those are already taken care of by `dhclient-script`.
The issue is that the case-statement we use to detect this doesn't catch
options like `ip=dhcp,dhcp6`.
Fix this by reworking the logic here to just check if a
`setup_net_$netif.sh` hook exists. If so, then we know that `setup_net`
will be called for this interface later.
This was causing issues in RHCOS which now ships with `ip=dhcp,dhcp6` to
support IPv6 environments[1]. The code here would make us do `setup_net`
pre-emptively which IIUC would then cause the initqueue to finish
earlier even if we had more udev netif events to process.

Checks if `uefi_splash_image` exists in `dracutsysroot` if not unset
`uefi_splash_image`. Alternate Value parameter expansion adds section-vma
for splash image to EFI stub loader when the path to image is valid and
not an empty file.
I did not test on other distributions, but on Arch Linux the `systemd`
package includes a splash image at the path
`/usr/share/systemd/bootctl/splash-arch.bmp`. Perhaps, if this is a
common practice, a default image could be gathered from that directory.
It is required that the image be in bitmap (`.bmp`) format according to
`splash.c`.
The code for `stub.c` and `splash.c` can be found at:

This reverts commit c603419030.
wait_for_ipv6_dad_link is only called from dhclient script,
so the original intent "wait for IPv6 RA if using none/static IPv6 assignment"
does not seem to be correct.
Anyway, this brings an issue on isolated networks, where you don't
have any routes outside. dhclient-script hangs on this check
and after it times out, dhclient is able to set the address normally.
Due to the way dracut-install handles modules from custom kmoddirs, add
a test that ensures the kmoddir argument seems sane.
In addition to erroring out, provide some guidance on how to proceed, as
well as a method of skipping the test via environment variable.
dracut, when passing --kmoddir, would only install modules that exist at
the same location as it will appear in the initramfs.
For most (possibly all) outputs, the output path would be /lib/modules,
so previously all kernel modules must be copied there or the module
installation silently fails.
Now use the original path variable, and install to the shortened path
variable (as calculated by kerneldirlen).
Note: This means that the argument to --kmoddir (and the modules filetree)
should be a directory that ends in 'lib/modules/$kernelversion'.
Some distributions (Arch, Gentoo) ship prepacked microcode images. These
are cpio images that follow the structure specified in the Linux kernel
documentation (x86/microcode.rst, "Early load microcode"), the same
structure dracut uses for its early microcode images.
In case of Arch Linux, the microcode for Intel CPUs is currently only
available in this packed form, /usr/lib/firmware/intel-ucode does not
exist. This commit adds a way to make use of these images on such
systems by unpacking them to the early cpio directory. (Note that the
packed image cannot be used directly since dracut might need to add ACPI
tables to the early initramfs.)
This approach has the drawback that it is not possible to control the
selection of CPUs to be included in the microcode file in host-only
mode, so we only try it as a last ressort if no unpacked microcode could
be found in fw_dir.
The list of possible file names for the packed microcode image is taken
from GRUB (cf. GRUB_EARLY_INITRD_LINUX_STOCK), but can be adapted by
setting "early_microcode_image_name" (and "early_microcode_image_dir")
in a dracut configuration file.
Otherwise we won't retry dhclient again on that interface. In
FCOS/RHCOS, we want to bake in `ip=dhcp,dhcp6` so we automatically try
getting a DHCPv6 lease if DHCPv4 failed.

If hostonly mode is in use, and there isn't any block device included
as hostonly device, then the initramfs won't need any block driver.
Eg. for kdump built image, there could be only one nfs mount point,
or the initramfs may only execute some network operation then reboot.
In such case, skip block driver installation to save space and time.

Setting up the machinery to boot with the aid of real networked boot loader
(such as iPXE) would involve much hassle, including possibly serving the kernel
and initrd via TFTP, etc.
Let us generate the iBFT table ourselves, with a Perl script. Include the
pregenerated table as well so that the test run won't depend on Perl. In the
end it's just reproducibly built static data, totally independent of the host
system.
New systemd defaults to generating MAC addresses for software devices (whereas
previously they would inherit them from the first enslaved slave).
Sadly, among the things this breaks is our test fixture, where the dhcp servers
are configured to expect a particular MAC address. Disable this for the
affected tests, which are essentially the ones that use bridges and bonds.
The network interfaces appear asynchronously and sometimes just too late,
after we're already halfway throught server-init.sh:
+ ip link set dev eth0 name ens3
Cannot find device "eth0"
+ ip addr add 192.168.50.1/24 dev ens3
Cannot find device "ens3"
+ dhcpd -cf /etc/dhcpd.conf -lf /var/lib/dhcpd/dhcpd.leases ens3 ens5
...

[ 8.047105] e1000 0000:00:03.0 eth0: Intel(R) PRO/1000 Network Connection
...
No subnet declaration for ens3 (no IPv4 addresses).
** Ignoring requests on ens3. If this is not what
you want, please write a subnet declaration
in your dhcpd.conf file for the network segment
to which interface ens3 is attached. **
Whoopsie. Let's ensure all the interfaces are there before we proceed

commit 5e0f8c8a4c ('network-manager: remove useless use of basename')
somewhat carelessly didn't take into account that $_i has a slash at
the end which made the result of the ## substitution be just an empty
string.
The slash was put to the end of /sys/class/net/*/ to make sure we're only
iterating directories, but it's not strictly necessary. In an unlikely case
something else than a directory appears in /sys/class/net/, we'll already deal
with it gracefully. Remove it.
This fixes the TEST-30-ISCSI test.
E.g. in RHCOS, the `BOOT_IMAGE` from the cmdline is:
(hd0,gpt1)/ostree/rhcos-e493371e5ee8407889029ec979955a2b86fd7e3cae5a0591b9db1cd248d966e8/vmlinuz-4.18.0-146.el8.x86_64
Which of course is a GRUB thing, not an actual pathname we'll be able to
resolve. In fact, we can simply scrap it off from the variable. Our code
is already able to handle both cases: whether the device refers to a
separate boot partition, or just the root filesystem with a regular
`/boot` directory.
It's already the case the `BOOT_IMAGE_PATH` today, in the non-empty
case, includes a trailing `/`, but let's add it to the path we build
here too to make it more obvious.
That way, the HMAC file can contain a relative path instead of an
absolute one. The issue is that right now the kernel RPM bakes the
`/boot/vmlinuz-${kver}` path into the HMAC file which poses an issue for
rpm-ostree systems (and any other system where the kernel isn't simply
in the top-level `/boot`.
For now, we're hacking around this in rpm-ostree:
https://github.com/coreos/rpm-ostree/pull/1934
Though I'd like to propose the same change in the kernel spec file.
There is a small regression in #343: when handling the 'separate boot
partition' case, we're checking for the kernel image in the wrong
location: `BOOT_IMAGE` is the `/boot`-relative path to the kernel image,
so `/boot/${BOOT_IMAGE_PATH}/${BOOT_IMAGE}` expands to e.g.
`/boot/mysubdir1/mysubdir2/mysubdir1/mysubdir2/vmlinuz...`.
We should be using `BOOT_IMAGE_NAME` here instead (and in fact, the next
if-statement does this correctly, so it might've just been accidentally
left out of #343).
For the shell scripts, new environment variables were introduced.
dracutsysrootdir is the root directory, file existence checks use it.
DRACUT_LDCONFIG can override ldconfig with a different one that works
on the sysroot with foreign binaries.
DRACUT_LDD can override ldd with a different one that works
with foreign binaries.
DRACUT_TESTBIN can override /bin/sh. A cross-compiled sysroot
may use symlinks that are valid only when running on the target
so a real file must be provided that exist in the sysroot.
DRACUT_INSTALL now supports debugging dracut-install in itself
when run by dracut but without debugging the dracut scripts.
E.g. DRACUT_INSTALL="valgrind dracut-install or
DRACUT_INSTALL="dracut-install --debug".
DRACUT_COMPRESS_BZIP2, DRACUT_COMPRESS_LBZIP2, DRACUT_COMPRESS_LZMA,

DRACUT_COMPRESS_LZOP, DRACUT_COMPRESS_ZSTD, DRACUT_COMPRESS_LZ4,
DRACUT_COMPRESS_CAT: All of the compression utilities may be
overridden, to support the native binaries in non-standard places.
DRACUT_ARCH overrides "uname -m".
SYSTEMD_VERSION overrides "systemd --version".
The dracut-install utility was overhauled to support sysroot via
a new option -r and fixes for clang-analyze. It supports
cross-compiler-ldd from
https://gist.github.com/jerome-pouiller/c403786c1394f53f44a3b61214489e6f
DRACUT_INSTALL_PATH was introduced so dracut-install can work with
a different PATH. In a cross-compiled environment (e.g. Yocto), PATH
points to natively built binaries that are not in the host's /bin,
/usr/bin, etc. dracut-install still needs plain /bin and /usr/bin
that are relative to the cross-compiled sysroot.
The hashmap pool allocate_tile/deallocate_tile code was removed
because clang-analyze showed errors in it. hashmap_copy was removed
because it wasn't used and clang-analyze showed errors in it.
DRACUT_INSTALL_LOG_TARGET and DRACUT_INSTALL_LOG_LEVEL were
introduced so dracut-install can use different settings from
DRACUT_LOG_TARGET and DRACUT_LOG_LEVEL.

Intel has notified us that some microcode updates are not safe
to be applied during runtime. To accomodate for that, microcode
files shipped by SUSE and openSUSE have an '.early' postfix such
that triggering

still allowing the code to be picked up during initrd time.
This change is needed to make this scheme work also in a hostonly

Currently, this affects only 06-4f-01, which is now 06-4f-01.early.

According to the dracut README, module code to be run in
the initrd must be POSIX-compliant. Replace remaining
bashisms (as reported by checkbashisms) with POSIX compliant
code.
The use of "type" is not strictly POSIX compliant, but it's
all over the place in dracut code. dash supports it, anyway.
In multipath scenarios, "iscsiadm -m node" may contain
several records with the same target.
There's no point in trying "iscsiadm --login" multiple
time for the same target, through the same portal.
Moreover, warn if the desired target is not on the node
list.
dracut waits for every iscsiroot connection to be established
before switching root. This is not necessary in multipath scenarios,
where a single path is usually sufficient to set up the root device,
and where users expect booting to succeed unless all paths are down.
Don't wait for the iscsi portal to start if the root device has
already been found.
For handling the configuration where there are two
paths to an iscsi root target, each using a different
NIC. In such a case, the initramfs was trying to configure
the first NIC, then call iscsiroot to login to both targets,
which would fail for the 2nd target, since the path to the
2nd target was not yet configured. This would eventually
work after a timeout. But it's better to login to just
one target at a time.
This change makes the initramfs handle multiple paths to an
iscsi target better by logging into only one target at a time,
rather than trying to login to all targets when only one of
several NICs is up.
This can be further optimized by using the initrd parameter
"rd.iscsi.testroute", which would skip iscsiadm login attempts
for targets to which no route exists.
If the script is called again via the timeout initqueue,
we try "iscsiadm -L onboot" again, hoping that some targets
may now have become reachable.

Starting with the 0.7.7 release of the multipath tools, the multipath
udev rules always set a value in ENV{DM_MULTIPATH_DEVICE_PATH} for any
device that multipath scans. A value of 0 means that the device is not
claimed by multipath, and a value of 1 means that it is. Because of
this, udev rules that check ENV{DM_MULTIPATH_DEVICE_PATH}=="?*" will
always return True, and act as if every scanned device is claimed by
multipath. Checking ENV{DM_MULTIPATH_DEVICE_PATH}=="1" will work
correctly for both the old and new versions of the multipath tools.

When you install a third-party driver, you will probably end in a
situation, where the module will be in a different directory and
in $depmod_module_dir you will only have symlink. If we resolve the
symlink before we pass the module path to instmod, the dracut-install
will only include the module with its original path, but not the
symlink. Hence the module can't be automatically loaded.
Dracut-install is clever enough to handle symlinks and will include both
the symlink and the module to the initrd.
In e54ab383 we moved the fips script to a later pahse of boot, since
the /boot might not be available early on.
The problem is that systemd-cryptsetup* services could be run now
started before the do_fips is executed and need the crypto modules
to decrypted the devices.
So let's split the do_fips and load the module before udev does the
trigger.
When DRACUT_SYSTEMD is set and DRACUT_QUIET=yes, vinfo returns 1. This
is a problem for hooks which end with vinfo, as then the hook returns 1.
Especially problematic if this is a shutdown hook, as it will be
restarted again and again.
This commit fixes that.

on line 1086 it's used to check for the uefi_stub:
"${systemdutildir}/boot/efi/linux${EFI_MACHINE_TYPE_NAME}.efi.stub"
so it needs to be defined before that
The EFI executables produced by dracut --uefi must be placed in the
subdirectory /EFI/Linux of the EFI system partition (ESP) according to
the Boot Loader Specification, see
https://systemd.io/BOOT_LOADER_SPECIFICATION#logic
This is done correctly for the mount points /boot and /boot/efi, but for
the mount point /efi, the files are placed in /efi/Linux instead of the
correct /efi/EFI/Linux. This commit fixes the directory so that the EFI
executables are picked up correctly by conforming boot loaders.
Apart from complying to the specification, the change is also in line
with the commit message of 5c57209ba5
("dracut.sh: add default path for --uefi") which introduced this feature
as well as the documentation in dracut.8.asc.
If the network-manager plugin is used instead, it wouldn't write out
ifcfg files and we wouldn't have anything to check.
While at that, also enable the test.
The IFCFG test will make sure the network-legacy plugin keeps writing
out correct ifcfg files.
This is a separate commit so that actual changes are visible in the
following one.
If the root is on network, let nm-initrd-generator create configuration
even if none was explicitly specified on the command line.
Also do the same if /tmp/net.ifaces exists, because the anaconda plugin
creates an empty file in that location in hopes that will make us
configure the network.
On Fedora 30 the paritition sizes turn out to be too small again:
+ mkdir -p /sysroot
+ mount /dev/dracut/root /sysroot
+ cp -a -t /sysroot /source/bin /source/dev /source/etc /source/lib /source/lib64 /source/proc /source/root /source/sbin /source/sys /source/tmp /source/usr /source/var
cp: error writing '/sysroot/usr/lib64/libkrb5.so.3.3': No space left on device
cp: error writing '/sysroot/usr/lib64/libkrb5support.so.0.1': No space left on device
It turns out that there has been quite some size increase in some libraries,
notably glibc, though not all -- some even shrunk, ruling out a toolchain
problem. Here's are files over 1M we install on Fedora 30:
f29 f30
2.7M => 6.4M /usr/lib64/{libc-2.28.so => libc-2.29.so}
3.1M => 6.0M /usr/lib64/libcrypto.so.1.1.1c
2.0M => 3.5M /usr/lib64/{libm-2.28.so => libm-2.29.so}
2.9M => 2.8M /usr/lib/systemd/{libsystemd-shared-239.so => libsystemd-shared-241.so}
1.7M => 2.5M /usr/lib64/libunistring.so.2.1.0
2.3M => 2.4M /usr/lib64/bind9-export/libdns-export.so.1105.0.0
1.2M => 2.1M /usr/bin/bash
1.1M => 1.4M /usr/lib64/libkrb5.so.3.3
1.2M => 1.4M /usr/lib64/libgcrypt.so.20.2.4
612K => 1.1M /usr/lib64/libssl.so.1.1.1c
This increases the image sizes to accomodate for this. There's probably
little else we can do.
The kernel may only enable 'libfcoe' module. Some modules like bnx2fc

drivers if it's required. So no need to install it in installkernel.

When a module is compressed, uncompress it before packing into initrd.
Since initrd is already compressed, it makes no sense to put the
compressed module files.
The patch contains a slight refactoring and adds a helper function to
get the command for uncompressing a file per extension.
Bash 5 apparently longer propagates variable assignments to local variables
in front of function calls when in POSIX mode:
[lkundrak@demiurge ~]$ cat feh.sh
print_VAR () {
echo "$VAR";
}
testfunc () {
local VAR="OLD"
VAR=NEW print_VAR
}
testfunc
[lkundrak@demiurge ~]$ bash4 --posix feh.sh
NEW
[lkundrak@demiurge ~]$ bash5 --posix feh.sh
OLD
[lkundrak@demiurge ~]$ bash5 feh.sh
NEW
[lkundrak@demiurge ~]$
It works the way it did in Bash 4 in non-POSIX mode, for external programs,
or for non-local variables. Don't ask me why -- it's probably some
compatibility thing for some sad old people.
However, this precisely happens when fsck_single() is calling into the
fsck_drv_com(), assigned to _drv by fsck_able(). That ruins the
TEST-70-BONDBRIDGETEAMVLAN test's server and probably more.
Let's pass the fsck driver binary via the function argument instead. It's
less messy anyway.
- The network script and config could be in
"/etc/sysconfig/network-scripts", so try look for network config in

systemd binary and udevadm are not needed to be outside the squash
image. Some binaries are kept outside because they are required before
mounting the image, or after umounting the image (when switching root),
or they may block umounting the image. But we are using lazy umounting,
so actually nothing will block the umount.
Keep more binaries outside the squash image won't hurt but cost extra
memories, the idea of squash image is to save memory usage.
So, there is no reason to keep udevadm outside, that should be a debug
left over. For systemd binary, it's running when switch root happens,
But we have lazy umounted the image and overlay, once systemd process
exec the new systemd in new root, everything will be cleared by kernel.

Previous in commit 7047294, dracut will include the loaded kernel module
list in initramfs, so other tools could check if the loaded kernel
module is changed and rebuild the host only initramfs in case some
module required to boot the machine is missing due to host only install.
It's better to use modalias list generated by dracut-install, that
list includes the device modalias list combined with current loaded
kernel module list. In this way, if any kernel module is yet to be
loaded when the initramfs is built, or got unloaded by accident the
module list will not change. This make the list more stable over
initramfs builds.

The upcoming kernel will have a support for loading compressed
firmware files, and this patch corresponds to that kernel change.
When a firmware file with the extra .xz extension is found, dracut
copies to initrd as fallback. Since initrd itself is compressed, the
file is uncompressed in initrd beforehand.
When using dracut with --hostonly and --no-hostonly-default-device,
/boot will be inaccessible as dracut will most fs modules unless
specified. But FIPS require /boot to be accessible, and it will try
to mount it on boot. It will fail if corresponding fs module is missing.
For most case /boot will be a simple partition, include the fs module
will be enough for FIPS to mount it. For other cases users have to pass
extra parameters by themselves.

The recent systemd upstream introduced a slightly modified version
string which included information about a git commit, which however
broke the version check in dracut. Unfortunately, the (( )) bash syntax
went along with it in certain cases and introduced a pretty nasty issue,
when the systemd would boot up but with slightly changed environment.
To prevent this from happening in the future, let's at least check if
the version parsed from the `systemd --version` output is a comparable
number.
Eliminate erroneous substring matches when looking up already processed keymaps to prevent necessary keymaps not getting added to the initramfs sometimes e.g. if there are the files 'compose.latin1' and 'compose.latin1.add' the unfixed version would skip processing 'compose.latin1' if find returned 'compose.latin1.add' first due to the directory listing not being in sorted order.
Images built with the fcoe module will always run the lldpad
service as part of their pre-trigger scripts if the network
is active. This prevents network installations in
environments where, for security reasons, LLDPDU frames
cause a switchport shutdown.

lldpad.sh script and the entire 95-fcoe module.

The new shutdown.sh will remount the squash image and then everything

The previous logic would not handle absolute paths on the left side of

At runtime, the kernel tries to load the file from /lib, and fails if we
only provide it in /lib64.
Instead of looking for the first slash after the "=>", just look for the

would contain such an entry in DT_NEEDED.

No way. Just ensure the links are there in the initramfs image. In fact,
that is already the case for iscsiuio.socket. Add iscsid.socket too.
If the network module obtained a lease using dhclient, NetworkManager
must be configured to use it too, otherwise it would obtain a different
lease (and could potentially break a connection to the network volume).
With all files stored in ramfs, and most of them are not compressed,
the initramfs will take up a lot of memory. Besides, if the file number
is large, each file will waste some memory due to page fragmetation.
This is due to ramfs' design, at least one page will be allocated for
one file however small the file is. On machine with large page size,
this will become worse and waste too many memory.
One approach to reducing the memory usage is to reduce the number of
files that got directly loaded into the root ramfs, and compress files
by put most files will into a read-only squash image and keep a minimum
set of executable and libraries outside as the loader for the squash
image. After the squash image is mounted, the real 'init' will be
executed and then everything behaves as usual.
This patch will introduce a '99squash' module which will never be
included by default. User can force add it, and if it is included,
dracut will perform some extra steps before creating the final image:
For now, "/etc" and "/usr" will be moved into the squashfs image.
"/init" will be renamed to "/init.stock" and replaced by "/init.squash".
Files and folders need to be accessible before mounting the image will
be still avaliable at their original place. And due to squashfs is
readonly, an overlayfs layer will be created on top of squashfs mount
point, as many dracut module require readwrite access to "/etc" and
"/usr", "init.squash" will ultimately call "/init.stock".
An extra systemd service will be installed. This service will umount all
squashfs related mount points right before switch-root to release
resources properly. This service will not actually do anything if
switch-root is not used.
This is very helpful when mem resource is very limited, like Kdump.
According to my tests, this squash module can help save about 35MB of
memory with 64K page size, or about 15MB with 4K page size on an
ordinary kdump capture routine. This module could also help reduce
memory usage for normal boot up process.
Won't change any behavior if squash module is not enabled.

Bug: https://bugs.gentoo.org/602122
On my system the following initrd-release is generated:
...
VERSION="4 dracut-048 dracut-048"
...
VERSION is not defined in /etc/os-release, so the variable is
concatenated with its previous value:
* "4" comes from the kernel build system since dracut is called from the
kernel install hook ("4" is a major kernel version);
* first "dracut-048" comes from the "systemd-initrd" module;
* second "dracut-048" comes from the "base" module.
This is what happened before this patch (edited for brevity):
dracut-cmdline-ask.service in modules.d/98dracut-systemd, which invokes
dracut-cmdline-ask.sh. This script and systemd-vconsole-setup are
started in parallel for the same console (tty1).
Then dracut-cmdline-ask quits immediately without doing anything (unless
rd.cmdline=ask is given). As this is a bash script and it gets tty as
stdin as specified in its *.service, this triggers the hangup of tty1 at
its exit.
Meanwhile systemd-vconsole-setup continues and tries some ioctls after
that, but they fail because of the hung up tty1.
The usual culprit for starting systemd-vconsole-setup early on is
plymouth-start.service, even if plymouth.enable=0 is set.
A popular (and annoying) symptom of this as reported by users was
the inability use their configured keyboard layout in plymouth when
unlocking their crypted block devices.

A hostonly image will not include every possibly required kernel module,
so if any hardware or configuration changed, the image may fail to boot.
One way to know if there are any hardware change or configuration change
that will require an image rebuild or not is to check the loaded kernel

time, then the image may require to be rebuilt.
This commit will let dracut record the loaded kernel module list when

list with currently loaded kernel modules to decide if dracut should be
called to rebuild the image.
To retrieve the loaded kernel modules list when an image is built, use
lsinitrd command:

This commit basically reverts 5ce7cc73
90-multipath-hostonly module was added in 5ce7cc73, because if hostonly
mode is enabled, multipath module will always hardcode wwids which
causes problems when the initramfs is cloned to another system with same
hardware.
Now with tri-state hostonly mode, the two modules could be merged and only
hardcode wwids when "strict" hostonly mode is enabled.
Only pick rules for interfaces which have a carrier in the running
system. Those interfaces will be assembled by udev to allow booting
from those devices (i.e. iSCSI).
Reference: FATE#323440
Add a new option --hostonly-mode which accept an <mode> parameter, so we have a tri-state hostonly mode:
* generic: by passing "--no-hostonly" or not passing anything.
"--hostonly-mode" has no effect in such case.
* sloppy: by passing "--hostonly --hostonly-mode sloppy". This
is also the default mode when only "--hostonly" is given.
* strict: by passing "--hostonly --hostonly-mode strict".
Sloppy mode is the original hostonly mode, the new introduced strict
mode will allow modules to ignore more drivers or do some extra job to
save memory and disk space, while making the image less portable.
Also introduced a helper function "optional_hostonly" to make it
easier for modules to leverage new hostonly mode.
To force install modules only in sloppy hostonly mode, use the form:
hostonly="$(optional_hostonly)" instmods <modules>

Dracut uses the module deps to determine module dependencies
but that only works for modules with hard symbolic dependencies.
Some modules have dependencies created via callback API's or other
methods which aren't reflected in the modules.dep but rather in
modules.softdep through the use of "pre:" and "post:" commands
created in the kernel with MODULE_SOFTDEP().
Since in dracut we are only concerned about early boot, this patch
only looks at the pre: section of modules which are already being
inserted in the initrd under the assumption that the pre: section
lists dependencies required for the functionality of the module being
installed in the initrd.

Since the kernel doesn't allow using any non-FIPS-compliant crypto
algorithms, it doesn't make sense to install them. Even if they are
installed, tcrypt will not test them anyway.
Tested on Fedora 28 x86_64 by booting with fips=1 (with hand-patched
module-setup.sh).
This patch cleans up the default list of kernel modules in the 01fips
dracut module. All the algorithms that are tested in tcrypt are listed
by their algorithm name so that all the generic implementations and
drivers are picked up automatically based on the module alias.
This drops several unneeded modules and even a bogus one (rot13 -- this
one was obviously copy-pasted from tcrypt.c where it was listed as an
easter egg :).
The patch adds also some algorithms that weren't included in the
original set. It turns out in FIPS mode we only need those algorithms
that are marked as FIPS-allowed in testmgr.c (failure to find a non-FIPS
algorithm is ignored). The non-FIPS algorithms are further removed in a
subsequent patch.
since kmod-25 keyword "external" was implemented in order to avoid
additional actions(like weak-modules) when kernel was updated, which
makes it more simple while kernels' kabi were compatible.
but if move some special modules such as megaraid_sas, mpt3sas and
so on, to a external path like /opt/modules, these modules will not
be install to initramfs by default, which make the initramfs can't
be used to boot for disk detection failure.
according to kmod's document, you must specify a absolute path with
"external" keyword, so scan the lines in modules.dep that begin with
"/" and install them, to make sure necessary modules in external path
can be installed to initramfs too.

After the $COMMAND case statement, the exit status of the last executed

But for the "add" pattern, this last executed command is an arithmetic

both $? and $ret are 0, then the arithmetic expression evaluates to 0
so is considered false and has an exit status of 1.

When dracut silently produces a broken initramfs, then the system will
likely not boot and this can be very problematic. Typical use case is
after the kernel has been updated.
It appears that dracut is not protected against the BASH_ENV variable,
causing various scripts called by dracut to possibly fail or provide
wrong output (e.g. "ldd" is one of these).
Having a broken output for "ldd" makes the generated initramfs be not
usable, typically because vital binaries will be missing (e.g.
"awk", "udevadm", ...).
Note: because the shebang line cannot contain more than one argument,
the '--norc' option had to be removed. IMHO, it was useless anyway.

In kdump, if dump-target is ssh on ipv6, we need to sync until ipv6 addr
is ready. Currently ip=auto6/dhcp6 provides such function. But in 1st kernel,
it is hard to know whether the ipv6 addr is got by dhcpv6 or SLAAC.
E.g ifcfg-eth* contains DHCPV6C=yes direction, but there is no dhcpv6
server in the network, and then after the system is up, the user
echo 1 > /proc/sys/net/ipv6/conf/eth0/autoconf && accept_ra by manual
to obtain a ipv6 addr. Or vice.

If a process (maybe plymouth) was still pinning /oldroot, then shutdown

Commit 5e574046e76e ("5?-dracut*.install: Allow scripts to install

Unfortunately, it broke the rescue initramfs generation when it's

It checks for the 0-rescue sub-dir to exist, but this is created so
instead if the parent sub-dir exists has to be checked. Also, check

Previously if no symmetric key was configured for EVM, then the
initialization process was aborted. It can be a valid use case, however,
to only use EVM digital signatures. In this case only X.509 certificates
need to be loaded.
With this change EVM initialization will continue if any of the
symmetric or X.509 keys could be loaded.
This implements logic analogous to the one already implemented in
ima-keys-load.sh, only for the .evm/_evm keyrings.
If the kernel was built with CONFIG_IMA_TRUSTED_KEYRING then the kernel
initially creates and configures .ima and .evm keyrings. These keyrings
only accept x509 certificates that have been signed by a local CA which
belongs to the kernel builtin trusted keyring.
Thus if such a keyring is already present then additional evm keys
should be loaded into them. If this is not the case then the _evm
keyring needs to be created in userspace and keys will be loaded into
it instead.
Before this change dracut always created the _evm keyring and loaded
keys into it without considering an existing .evm keyring. In case of
CONFIG_IMA_TRUSTED_KEYRING being enabled, the _evm keyring will not be
used by the kernel, however, and EVM digital signatures will not work as
expected.
We initially enabled it for Haswell TSX bug (mga#16657)
Now there is also Meltdown and Spectre security issues,
and more microcode issues will most likely show up...

There is currently no way to override dracut's preference for
/dev/mapper device names. But using these is problematic in
different scenarios: For example, if a user has a multipath-
enabled system but wants to disable multipath, or if the
names of multipath maps change because of configuration changes
(e.g. toggling user_friendly_names in /etc/multipath.conf).
This patch makes dracut prefer the user-specified
--persistent_policy names over /dev/mapper names.
It might be worthwhile to discuss why dracut prefers /dev/mapper
of /dev/disk/by-uuid at all. This preference was introduced
in 9037b63e with the argument "dm devices maintain /dev/mapper/* as
persistent names", but that's wrong for the scenarios mentioned
above, and is not a compelling reason for preferring /dev/mapper
over /dev/disk/by-uuid.

According to Cathy Zhou <Cathy.Zhou@Oracle.COM>:
"iscsistart is not designed to be working together with iscsid. When an
interface gets the dhcp offer successfully, the iscsiroot script is run
which starts the iscsistart service to establish the iSCSI session. With
the existence of iscsid, the iscsistart service's attempt to setup its
own mgmt ipc fails. Instead, the request to login to the iscsi target
is handled by the mgmt ipc of iscsid. After iscsistart finishes its
login attempt, it eventually sends a stop_event_loop request to stop
the mgmt process. As the result, it terminates iscsid."
So, iscsid is kicked out again.
Additionally iscsistart-flocked is used to make sure iscsistart is not

Old code did not work for two most common use-cases.
On most machines BOOT_IMAGE is set to something like
/vmlinuz-4.11.3-202.fc25.x86_64. So if we just add prefix "/boot/."
it won't work. Also on machines without /boot on separate partition
BOOT_IMAGE already has the /boot/ prefix (/boot/vmlinuz-3.10.0-799.el7.x86_64).
So let's strip it in such case.

The needle argument in this specific case is a pattern, which cannot be

This can result in fsck calls like:

Which will then exit with an error like:
e2fsck: Only one of the options -p/-a, -n or -y may be specified.
Hence, it is necessary to use the strglobin function to correctly match
the pattern.
The "host" command may also print something else than
"asdf.local.lan has address 1.2.3.4", like:
"rootserver.local.net is an alias for rainbow.local.net.".
So "head -n1" is not enough.

Type=oneshot, as currently set in dracut's emergency service file,
causes an awkward situation if emergency mode is entered e.g. because
of a root device timeout, and the root device appears later because it
just has taken longer than the timeout. In that situation, my
expectation (backed by past positive experience) is that the user should
be able to simply exit the emergency shell and resume normal boot.

Failed to start default.target: Transaction is destructive.
(system keeps idling from this point on, user has no chance to
do anything).
This results from the combination of two effects:
1) initrd-root-fs.target sets "OnFailureJobMode=replace-irreversibly",
2) emergency.service's Type=oneshot causes the start jobs for both
emergency.service and emergency.target to persist while the user is in
the emergency shell.
When the shell is exited, systemd tries to isolate "initrd.target"
again, but this fails with "the transaction is destructive" error
because of the still pending jobs.
This patch fixes this by changing the Type of "emergency.service" from
"oneshot" to "idle".
JobRunningTimeoutSec now affects how long can start jobs for device
units stay in the "running" state. Disabling default job timeout via
JobTimeoutSec=0 doesn't disable running state timeout. We need to set
running state timeout as well.
Note that doing this the other way around has effect on generic timeout,
i.e. disabling running state timeout disables generic timeout. But doing
it this way we would create implicit dependency on fairly new
systemd-234. However, by setting both options we don't create dependency
on specific systemd version.
A LUKS root volume with a detached header on a device without partitioning will not have a UUID and will not have an attribute ENV{ID_FS_TYPE}=="crypto_LUKS".
Therefore, several areas need to be addressed: identification of the LUKS device, inclusion of entries within crypttab, and provision of the detached header file.
- Added support for an option (4th column: "force") in /etc/crypttab to force the inclusion of the entry in the initramfs version (avoiding the fs type test).
- Added support for an option (4th column: "header=/path/to/file") in /etc/crypttab to provide a path to a detached header file embedded within the initramfs.
- Added ID and PARTUUID support to the device (2nd column) in /etc/crypttab (complementing the existing UUID functionality).
- Added cmdline support to indicate LUKS device ("rd.luks.serial=") that refers to the attribute ENV{ID_SERIAL_SHORT}.
Tested successfully on Void Linux (x86_64 musl) (no systemd) with a LUKS root volume accessed with a keyfile and using a detached header.
Not tested on systemd, or on a LUKS root volume with a passphrase rather than a keyfile.
Some Combined Network Adapters(CNAs) implement DCB protocol
in firmware, it is recommended that do not run software-based
DCB or LLDP on CNAs that implement DCB, but we have to start
the lldpad service anyway(there might be other software DCB).
If the network interface provides hardware DCB/DCBX capabilities,
the field DCB_REQUIRED in "/etc/fcoe/cfg-xxx" is expected to
be set to "no".
We met an issue on "QLogic BCM57810" with DCB firmware support,
and found dracut still generated "fcoe=<mac>:dcb" which caused
kdump boot failure when using that fcoe dump target.
This patch parses /etc/fcoe/cfg-xxx to detect DCB_REQUIRED="no",
and force "nodcb" if it is the case.
Also improved some coding style in passing.

kerneldirlen is used to modify absolute path returned by

--kerneldir argument which can be a relative path.
Use kmod_get_dirname() to convert user-supplied path to the same format
as used by kmod_module_get_path().
This also allows to get rid of now useless strcmp checks that seem to
imply that /lib and /usr/lib are linked which is not always true.
Prior to this commit, the MTU setting was applied to a bond slave
interface. In older versions of the Linux kernel, this setting
propagated to the bond master and the other bond slaves associated with
the master. In recent versions of the kernel (observed in Linux 4.12),
increasing the MTU of a slave does not automatically increase the MTU of
the master. This allows for more flexibility but requires the MTU of
the master to be changed manually.
Ideally, the MTU setting should be applied to the bond master and the
setting will propagate to the bond slaves, since the slaves are required
to have a MTU that is greater than or equal to the bond master.

Kdump doesn't need default host devices like root, swap, fstab, etc,

due to one of those host devices added by dracut, additionally, the
needless devices(e.g. LVM) consume some appreciable amount of memory
which is more likely to cause OOM under memory-limited kdump.
So this patch introduced "--no-hostonly-default-device" to avoid

SSH uses passwd database and thus need various NSS plugin libraries,
depending upon setting in nsswitch.conf.
SSH binary fails within the dracut environment without the libraries:
#:/ ssh
No user exist for uid 0
In the module-build-service, we have pieces of dracut provided by different
modules ("base-runtime" provides most functionality, but we need
dracut-network in "installer". Since these two modules build with separate
dist-tags, we need to reduce this strict requirement to ignore the dist-tag.
The dracut network module is only supposed to be used for wired interfaces
but if driver modules for wireless devices are wrongly copied, these will
be loaded and the available interfaces brought up.
If the rd.neednet=1 command line parameter is used, dhclient will attempt
to request an IP address for the interfaces and these requests will fail.
But other dracut modules that depend on the network to be settled, will
have to wait for the DHCP requests to timeout. Which can be a lot of time
since the dhclient default timeout value is 60 seconds.
Instead of trying to blacklist all possible kernel modules for wireless
devices, only bring up network interfaces if these are for wired devices.

For example:

while our current code expects
new_classless_static_routes=32 10 198 122 47 192 168 78 4

curl in Fedora recently changed its default CA trust store. The
Fedora package no longer specifies an OpenSSL-format bundle file
during build, and curl itself has been patched to use an NSS
plugin called libnssckbi.so when no bundle file or directory is
specified. There are (at present) two possible providers of the
libnssckbi.so module: the original NSS implementation, which
uses a trust bundle built in at build time, and a compatible
implementation from the p11-kit project, which reads a trust
bundle at run time. So if we find a string in libcurl.so that
suggests libnssckbi might be in use, we must both install it and
make an effort to install any trust bundle files it may use.
The p11-kit libnssckbi implementation does include a string that
lists the top-level trust directories it will use, so we try to
find that string, though the best effort I can come up with will
also find many false positives too. To weed out the false
positives, we check whether the matches actually exist as dirs,
and if so, whether they contain some specific subdirectories we
know p11-kit trust dirs must have (thanks, @kaie). For the NSS
libnssckbi implementation, we will likely wind up not finding any
dirs that match the requirements, so we will simply install the
libnssckbi.so file itself, which is the correct action.
This fixes TLS transactions in the initramfs environment when
using a curl that's built this new way; it's significant for
use of kickstarts and update images with the Fedora / RHEL
installer, as these are retrieved in the initramfs environment,
and are frequently retrieved via HTTPS.
The --ignoreactivationskip/-K switch was added to LVM2 in 2.02.99
(July 2013) and is used to control the activation of volumes with
the activation skip flag set: without -K these volumes will be
ignored when 'lvchange -ay $LV' is issued.
This prevents an LVM2 thin-privisioned snapshot from being used
as the root device when booting with rd.lvm.lv=vg/lv since the
activation skip flag is set for these snapshots by default (the
legacy non-thinp snapshots do not set this flag and can already
be activated and used as a root device by specifying appropriate
values for rd.lvm.lv).
This is only used in the rd.lvm.lv case since in that situation
we are activating one or more named LVs specified by the user:
the flag is not given when calling 'vgchange' since this may
cause many unwanted volumes to be activated during early user
space. Users wishing to use a specific snapshot volume should
specify it with 'rd.lvm.lv'.
The previous algorithm was incorrect and would return
incorrect results e.g. for a /20 mask. Also gets rid
of an undocumented depencency on bc(1).

Provide a more prominent alert to the user if an overlay is
missing or the overlay module is not available and a temporary
overlay will be provided. This, to avoid losing data intended to
persist.
Integrate the option to use an OverlayFS as the root filesystem
into the 90dmsquash-live module for testing purposes.
The rd.live.overlay.overlayfs option allows one to request an
OverlayFS overlay. If a persistent overlay is detected at the
standard LiveOS path, the overlay & type detected will be used.
Tested primarily with transient, in-RAM overlay boots on vfat-
formatted Live USB devices, with persistent overlay directories
on ext4-formatted Live USB devices, and with embedded, persistent
overlay directories on vfat-formatted devices. (Persistent overlay
directories on a vfat-formatted device must be in an embedded
filesystem that supports the creation of trusted.* extended
attributes, and must provide valid d_type in readdir responses.)
The rd.live.overlay.readonly option, which allows a persistent
overlayfs to be mounted read only through a higher level transient
overlay directory, has been implemented through the multiple lower
layers feature of OverlayFS.
The default transient DM overlay size has been adjusted up to 32 GiB.
This change supports comparison of transient Device-mapper vs.
transient OverlayFS overlay performance. A transient DM overlay
is a sparse file in memory, so this setting does not consume more
RAM for legacy applications. It does permit a user to use all of
the available root filesystem storage, and fails gently when it is
consumed, as the available free root filesystem storage on a typical
LiveOS build is only a few GiB. Thus, when booted on other-
than-small RAM systems, the transient DM overlay should not overflow.
OverlayFS offers the potential to use all of the available free RAM
or all of the available free disc storage (on non-vfat-devices)
in its overlay, even beyond the root filesystem available space,
because the OverlayFS root filesystem is a union of directories on
two different partitions.
This patch also cleans up some message spew at shutdown, shortens
the execution path in a couple of places, and uses persistent
DM targets where required.
Documentation is updated for these changes.

The current method for memory debug is to use "rd.memdebug=[0-3]",
it is not enough for debugging kernel modules. For example, when we
want to find out which kernel module consumes a large amount of memory,
"rd.memdebug=[0-3]" won't help too much.
A better way is needed to achieve this requirement, this is useful for
kdump OOM debugging.
The principle of this patch is to use kernel trace to track slab and
buddy allocation calls during kernel module loading(module_init), thus
we can analyze all the trace data and get the total memory consumption.
As for large slab allocation, it will probably fall into buddy allocation,
thus tracing "mm_page_alloc" alone should be enough for the purpose(this
saves quite some trace buffer memory, also large free is quite unlikey
during module loading, we neglect those memory free events).
The trace events include memory calls under "tracing/events/":
kmem/mm_page_alloc
We also inpect the following events to detect the module loading:
module/module_load
module/module_put
Since we use filters to trace events, the final trace data size won't
be too big. Users can adjust the trace buffer size via "trace_buf_size"
kernel boot command line as needed.
We can get the module name and task pid from "module_load" event which
also mark the beginning of the loading, and module_put called by the
same task pid implies the end of the loading. So the memory events
recorded in between by the same task pid are consumed by this module
during loading(i.e. modprobe or module_init()).
With these information, we can record the rough total memory(the larger,
the more precise the result will be) consumption involved by each kernel
module loading.
Thus we introduce this shell script to find out which kernel module
consumes a large amount of memory during loading. Use "rd.memdebug=4"
as the tigger.
After applying this patch and specifying "rd.memdebug=4", during booting
it will print out something extra like below:
0 pages consumed by "pata_acpi"
0 pages consumed by "ata_generic"
1 pages consumed by "drm"
0 pages consumed by "ttm"
0 pages consumed by "drm_kms_helper"
835 pages consumed by "qxl"
0 pages consumed by "mii"
6 pages consumed by "8139cp"
0 pages consumed by "virtio"

0 pages consumed by "crc32c_intel"
199 pages consumed by "virtio_console"
0 pages consumed by "libcrc32c"
9 pages consumed by "xfs"
From the print, we see clearly that "qxl" consumed the most memory.

Preserve extended attributes when copying files using dracut-install.
The copying of extended attributes avoids file execution denials when
the Linux Integrity Measurement's Appraisal mode is active. In that mode
executables need their file signatures copied. In particular, this patch
solves the problem that dependent libaries are not included in the
initramfs since the copied programs could not be executed due to missing
signatures. The following audit record shows the type of failure that
is now prevented:

IMA validates file signatures based on the security.ima xattr. As of
Linux-4.7, instead of cat'ing the IMA policy into the securityfs policy,
the IMA policy pathname can be written, allowing the IMA policy file

This patch first attempts to write the pathname, but on failure falls
back to cat'ing the IMA policy contents .

If emergency and shutdown-emergency hooks are called, the systemd should
poweroff the testsuite, therefore "rd.shell=0" is given on the test
suite kernel command lines.
"rd.shell=0" has to be parsed correctly by the test suite real root init
also.
Both 'utmp' and 'root' groups are mentioned in tmpfiles.d/systemd.conf
and as such should be included.
It's probably better to have something equiv to inst_rule_group_owner()
for udev rules which parses out users and groups and adds them to the
passwd/group db respectively.
Could also rely on sysusers but as the initramfs is static in this
sense, it's more efficient to pre-define the users IMO.
This will bundle clock drivers into the initramfs on arm
Tested on ti dm8148-t410 where adpll is needed on 4.6+ kernel
This will avoid to rely on (maybe broken) bootloader clocks.
Theses modules are also usually loaded early. Having them bundled into

I met a problem when passing kdump dns to dracut via "nameserver=x.x.x.x",
the dns I provided didn't appear in the "/etc/resolv.conf".
After some debugging, found that when setup dhcp DNS, in setup_interface()
and setup_interface6(), it has:
echo "search $search $domain" > /tmp/net.$netif.resolv.conf
So if "$search $domain" isn't NULL(this is ture in my kdump environment),
the dns contents(that is, dns1, dns2, nameserver) in "ifup" before dhcp
will be discarded.
This patch addresses it by handling dhcp first. In fact this is also the
way the NetworkManager in 1st kernel works.

If a module is renamed or another module takes care of the old one,
all of the alias strings have to be checked against the current set of
loaded modules.
This is still incomplete, because to be absolutely correct, all the
/sys/*...*/modalias files would have to be checked, if they match the
modules alias strings.
- use local variables with _
- use associative array for the kernel modules
- install emergency hook even in the systemd case
- follow device path until /sys is reached
- set kernel version for modprobe checking
If the initramfs was built with prefix=/run/... /run can't be mounted
with noexec, otherwise no binary can be run.
Guard against it by looking where /bin/sh is really located.

It is expected that a watchdog module will disable an active watchdog when
its probe is called ie, when it is loaded. So an early load of the module
will help to disable it earlier.

both are active.

Recently following patches have been added in upstream Linux kernel, which
(1) fixes parent of watchdog_device so that
/sys/class/watchdog/watchdogn/device is populated. (2) adds some sysfs
device attributes so that different watchdog status can be read.
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=6551881c86c791237a3bebf11eb3bd70b60ea782http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=906d7a5cfeda508e7361f021605579a00cd82815http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=33b711269ade3f6bc9d9d15e4343e6fa922d999b
With the above support, now we can find out whether a watchdog is active or
not. We can also find out the driver/module responsible for that watchdog
device.
Proposed patch uses above support and then adds module of active watchdog
in initramfs generated by dracut for hostonly mode. Kernel module for
inactive watchdog will be added as well for none hostonly mode.
When an user does not want to add kernel module, then one should exclude
complete dracut watchdog module with --omit.
Testing:
-- When watchdog is active watchdog modules were added
# cat /sys/class/watchdog/watchdog0/identity

# cat /sys/class/watchdog/watchdog0/state

By default, dracut only builds in dm-service-time into the initramfs as
that is the default multipath.conf path selector. If the user changes
the path selector to "round robin" on the fly and runs dracut, multipath
does not find any paths on boot and the user will be dropped into a
shell.
Apparently, in RHEL7 dracut defaults to "hostonly" mode, i.e. modules
not currently in use at the time dracut runs do not get built into
initramfs. This is definitely one case where this doesn't work. A change
to reconfigure multipath probably should not render the system
unbootable.

Once lvm2 starts using /run (bug 742554), it should be no longer
necessary to disable file-based locking in the vgchange call in
fedora-storage-init.
Removing '--sysinit' will make it safe to call LVM operations
concurrently from other units.
The --sysinit is a compound option consisting of:
-> --ignorelockingfailure - not needed anymore, the /run/lock/lvm is
available rw soon in boot process
-> --ignoremonitoring - not needed since /run is available, this would
require the dm-event.service to be run before
fedora-storage-init.service (and new lvm2-activation.service when
deployed). But that's a one line change - I'll have a look whether it
plays well with other services and if yes, I'll commit the change. N.B.:
This has a consequence that all volumes activated on vgchange -ay will
be monitored at the same time they're activated (which is a plus I
think). The lvm2-monitor will just grab all the other volumes not
activated at the time of the boot's vgchange -ay call. But that's not an
issue (for already monitored volumes, calling vgchange --monitor y will
just be a NOOP).
-> --poll n - not needed, we can run the polldaemon as the /run is
available and rw (in case there's unfinished merge or mirror sync from
previous system run, the poll-daemon will be triggered at boot now).
Actually, the polldaemon should be triggered as a service like dmeventd
is, not forked off from the LVM command itself, like from vgchange in
this case - we still need to change this - there's a bug open for this
request already (bug #814857). However, we don't have this feature ready
yet so I need to check whether this is OK with the early boot process
with the current state.
Transient snapshots can take advantage of smaller,
non-persistent metadata structures.

for the readonly_overlay target.

Newer lvms however do this automatically (not enabling an LV if the

Project maintainers are responsible for clarifying and enforcing our standards of acceptable behavior and will take appropriate and fair corrective action in response to any behavior that they deem inappropriate, threatening, offensive, or harmful.
Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, and will communicate reasons for moderation decisions when appropriate.
## Scope
This Code of Conduct applies within all community spaces, and also applies when an individual is officially representing the community in public spaces. Examples of representing our community include using an official e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be reported to the project maintainer responsible for enforcement Harald Hoyer <harald@redhat.com>.
All complaints will be reviewed and investigated promptly and fairly and will result in a response that is deemed necessary and appropriate to the circumstances.
Project maintainers are obligated to respect the privacy and security of the reporter of any incident.
Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
