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.

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

The existence of dpkg-achitecture is not indicative of a debian

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)

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

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).

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

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.

kerneldirlen is used to modify absolute path returned by

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.

needless devices(e.g. LVM) consume some appreciable amount of memory
which is more likely to cause OOM under memory-limited kdump.

SSH uses passwd database and thus need various NSS plugin libraries,

SSH binary fails within the dracut environment without the libraries:
#:/ ssh

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 "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.

hash algorithems, because even though most of them are probably
compiled in, older ones (e.g. md4 and arc4) usually aren't.
Contrary to previous intel pinctrl drivers, the cherryview driver can be
and usually is built as a module. However, it sets up the SDIO pinout
so sdhci can make use of the SD card reader, which may subsequently
hold a root file system on a card (bsc#998440).
Also change <= N to < N+1. For example, dracut-029-1 > dracut-029, so would not
get obsoleted properly. This all applies to old versions, so doesn't make much
difference in practice, so just fix it to avoid c&p duplication of the bad
pattern in the future.
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:

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

# dracut --hostonly initramfs-test.img -a watchdog

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.

in the boot sequence, and which are not needed while dract is running.
This can particularly happen when an md array is encrypted,
and the array is newly degraded so that it doesn't appear until
dracut runs mdraid_start.sh.
This can result in systemd printing warning messages which are
inappropriate.
So tell systemd that the timeout for each of these is zero.
This is involves splitting some functionality out of wait_for_dev()
That function does two things:
- creates 'finished' hooks so that dracut will wait for the device,
and
- sets the systemd timeout for the device to zero, so systemd doesn't
wait.
We only want the second of these for most encrypted devices.
So split that out into a new function set_systemd_timeout_for_dev(),
and call it from parse-crypt.sh

dracut: Make host only mode more resilient to missing swaps.
This patch set allows swap devices to disappear without cocking up a
host-only initramfs boot.
There is a bug that kdump-initrd contains entry requesting nfs dump
filesystem to get filesystemchecked. And there is an erro message said
that nfs need be checked. But there's no fsck for nfs utility, e.g
fsck.nfs like other file system. Whatever fs_passno 0 or 2 are passed,
no fsck is executed at all for nfs mount.But in dracut, set it to be 2
always, so the erro message appear and it should be set to 0.
In the fstab,the sixth variable fs_passno stands for that the device need
checked or not,and dracut set it to "2".To fix this issue, it should
be "0" when the device is nfs.The third variable stands for the type of
the filesystem and we can use it to judge whether the device is nfs.
So when the third variable of fstab contains "nfs", the sixth variable
fs_passno should be set to "0".

Although various bits are in place to cancel waiting for the /dev/resume
device (actually a symlink), we don't actually ever wait for it.
Also as the udev rule may create the symlink, silence any errors from
our manual ln -s call from the settled job.
The only reason we add swap devices to host-only mode (added in
dd5875499e) is to allow us to process
resume= arguments passed on the kernel command line when the swap
partition lives on something slightly more complex than a normal
partion (e.g. in an LVM or RAID setup).
By adding the device to host_devs, the necessary LVM and RAID hooks
are added and thus the underlying storage will be initialised OK, and
the 95resume module handles the waiting for the device (via udev rules
creating the /dev/resume symlink).
So ultimately, we do not need to hard-code the waiting for the swap
devices into the initramfs at build time as the waiting part can be
dynamic.
This makes things more resiliant to swap partitions disappearing and
being reformatted etc.
Inspired by a patch by Martin Whitaker on Mageia bug:
https://bugs.mageia.org/show_bug.cgi?id=12305
If crypt-lib.sh is sourced from any #!/bin/sh script, a POSIX shell
quirk is in effect that causes variable assignments to "special
builtins" (such as "shift") to leak to their context. So the buggy
code works even despite the missing semicolons.
But if it is sourced by "bash acting under its own name", i.e. from
any #!/bin/bash script, the quirk is disabled, tty_cmd/tty_prompt are
undefined, and ask_for_password doesn't do anything if plymouth is not
present.
AMD's HSA Linux kernel driver (amdkfd) has been merged into the mainline
kernel since kernel 3.19.
However, for the driver to work, it needs to be included in the default
initramfs image, together with the amd_iommu_v2 driver.
The radeon driver (AMD's kernel graphic driver) calls amdkfd during its
initialization and probing stages. Because radeon is included in the
initramfs image, it tries to initialize amdkfd during the early boot
stages. However, as amdkfd is not present there, it fails.
That doesn't harm radeon operation. However, it disables the HSA
abilities in the machine.
Because of the current design, if you later try to "modprobe amdkfd",
you won't be able to run HSA applications, even though the driver will
be loaded.

When 'systemctl daemon-reload' is run, systemd will clean out
/run/systemd/generator and re-run all the generators.
So it is important that the generators always create the required
files.
rootfs-generator.sh currently does *not* create the desired files
if $hookdir/initqueue/finished/devexists-${_name}.sh
exists.
This is not removed by "systectl daemon-reload" so the first time this
generator is run it will do the right thing. Subsequent times it
won't.
This results in incorrect timeouts after "daemon-reload" is run.
So let the existence of each file only guard the creation that file.

A number of timeout scripts can be registered. If any one of them
makes progress - e.g. assembles a degraded md array - then
the main loop should wait a bit longer rather than pressing forward.
This is particularly important is resume-from-hibernate requires a
degraded md array. Both the script to forcibly assemble the md array
and the script to abort hibernation if the device doesn't appear
are 'timeout' scripts. There needs to be a reasonable delay between
these running.
So: if any script has indicated that progress was made, break of out
the loop and go back to normal waiting.

mdraid_start is a number of scripts which run after a timeout.

When current dracut receives an ip with netmask of 255.255.255.255 via DHCP,
setting the also supplied default gateway fails (because it is obviously not
within the netmask).
The setup with a netmask of /32 is quite common in colocation datacenters
where you don't want the machines of two different customers to directly talk
to each other. At least two of the biggest colocation providers in Germany
(1&1 and Strato) do it that way. NetworkManager supports this kind of setup
and the dhclient-scripts of several distributions too.
In this patch I have implemented a simple approach very similar to what is
found in Debian. The dhclient-script from Fedora uses a more sophisticated
approach, but that relies on the ipcalc utility which would introduce a
dependency on Fedora-initscripts for dracut.

When the 'loop' kernel module isn't loaded in a running system, it gets
excluded from the hostonly initrd. Given that the crypt-loop dracut
module has to be loaded explicitly anyway, it makes sense to always
include the requisite loop kernel module.
When booting with 'rd.info', the 'info' statements in the crypt-loop
module's 'loop_decrypt' function are output to stdout along with the key
that gets piped into the 'cryptsetup' command, which causes the crypt
device unlocking to fail.
There are two possible simple solutions to this problem:
1. Redirect the info messages to stderr (just add '>&2' at the end of
the info statements).
or
2. Remove the info statements altogether.
I have tested both and they both work, but this commit implements #2.
The existing info messages are long (they overflow 80 characters
easily) and redundant (the password prompt clearly indicates what is
happening), and just generally not useful. Given that no one has
reported or fixed this bug in the three years that this module has
existed, no one will miss these info messages.
The commit also changes an error message in the same function to be more
descriptive.
With an EFI stub, the kernel, the initramfs and a kernel cmdline can be
glued together to a single UEFI executable, which can be booted by a
UEFI BIOS.
Basic systemd functionality is in 00systemd now.
Switching root and the initrd.target is in 00systemd-initrd.
Dracut additions to the systemd initrd are in 98dracut-systemd.
Previously rd.live.fsimg only supported filesystems residing in
(compressed) archives.
Now rd.live.fsimg can also be used when a squashfs image is used.
This is achieved by extracting the rootfs image from the squashfs and
then continue with the default routines for rd.live.fsimg.
In addition some code duplication got removed and some documentation
got added.

Dracut will generate systemd units for additional devices that should be
brought up during boot, e.g. swap devices. These unit files are broken
symlinks with \ in the filename, e.g.
/etc/systemd/system/initrd.target.wants/dev-disk-by\x2duuid-e6a54f99\x2da4fd\x2d4931\x2da956\x2d1c642bcfee5e.device.
Both the backslash and the broken symlink causes problems for shell
scripts, [ -e "$file" ] isn't enough and read requires the additional -r
argument to not react on the \.
The function 99shutdown/shutdown.sh:_check_shutdown() assumes that
shutdown scripts report success or failure via their return value.
However, "dmsetup remove_all" always reports success, even if some
of the device mappings could not be removed.
I submitted a patch for dmsetup but the lvm2 folks rejected it,
asserting that its behaviour is correct, that "remove_all" should
only be used by developers and that the proper solution would be
to invoke "dmsetup remove" on each device. This does report success
or failure via the return value.
Apart from fixing that issue, this commit also adds the dmsetup
option "--noudevsync". Without it, dmsetup would hang after removal
of a device while trying to communicate with systemd-udevd, which
is no longer running at this shutdown stage.

The sdhci-pci module is currently not being included in the initramfs,
even though other sdhci modules are. This breaks boot on systems that
rely on this driver to access the root filesystem.
Instead of looking for modules that use sdhci_pltfm_init, look for
sdhci_add_host. I checked 3.18 kernel sources, and this change
does not remove any of the previously-matched SDHCI drivers.
It should result in the addition of sdhci-pci, sdhci-s3c, sdhci-spear
and sdhci-acpi.

The space does not separate the elements reliably, spaces can be
embedded in parenthesized expressions too:
libgmpxx.so.4 (libc6, hwcap: 0x0000000004000000) => /lib/sse2/libgmpxx.so.4
libgmp.so.10 (libc6, hwcap: 0x0000000004000000) => /lib/sse2/libgmp.so.10
This results in dracut creating '0x0000000004000000' and '=>'
directories in the initramfs image.
When reading the --include part of the script, we had the following
issues to make the code easy to read:
- src & tgt were extract for the original options
- i variable was a file or a directory from src
- s variable was the directory name in case $i was a directory
"s" sounds very close to "src" while "s" is on the "tgt" side. Very
confusing.
"s" was defined before the "if it's a directory" statement while it's
only used inside the "if".
"i" was commit from the "src" but wasn't really explicit.
Having some lines mixing "i" and "s" takes a little time to get read
properly.
This patch offer the following changes:
- "i" is renamed to "objectname" as we don't know if its a file or a
directory
- "s" is renamed to "object_destdir" as the object name becomes a
directory on the destdir
- "object_destdir" (former "s") is moved inside the "if" statement as it's
only used here
- tgt is finally renamed to "target" to be more explicit. We are not all
native english ;o)
My 2 (semantic) cents,
When including a directory, the files were considered in the directory
name which lead to messages like :
cp: failed to access '/var/tmp/initramfs.L9s2zO///init-func': No such file or directory
This patch does make the destdir more explicit and copy files into the
destination directory instead of destdir/filename/

udevd will these days default to 'info' logging and thus will
often print out the 'starting version nnn' message (which is
logged at level 'info'), thus spamming the console, even on
'quiet' boots.
We generally expect a udev log level of err (the old default
from pre-October 2013) so we should set that explicilty before
launching udevd in order to suppress the spurious 'info' message.
As we are using the environment variable approach anyway, we
may as well use this method rather than setting the log level
later via udevadm control commands when rd.udev.info/debug are
given on the kernel command line.
The enviroment variable has been around since udev 6b493a20e1
around 2005 so should be safe to use in all cases without version
checks.

The synthetic keyboard of a Gen2 Linux VM doesn't work before the

Up until now, _check_shutdown() returns true if at least one of
the shutdown hooks succeeded. Change this to only return true if
*all* succeeded. To prevent an infinite loop, introduce an upper
bound of 40 iterations.
When you define the gateway for an interface, dracut sets it up with:
ip route add default via $gw dev $netif
If a default route is already set (e.g. if you have multiple NICs), this
will fail with the message "RTNETLINK answers: File exists".
So, if your first NIC isn't usable as a default route
Using "ip route replace default" instead allows ifup/dhclient-script to
correctly change the default route to the new interface.
loginstall specifies a directory, in which dracut-install records all
files, which were installed from the host system to the initramfs.
Use case is e.g. to create a list of packages to watch for updates, to
maybe trigger a recreation of the initramfs.
Which will not only add listed drivers, but also enforce that they are
tried to be loaded at early boot time.
This is needed if drivers which are not autoloaded (e.g. loop and a lot
others) shall get loaded via initramfs.
Otherwise dracut-logger.sh outputs an empty version on journal testing.

This patch adds bittorrent support to 45url-lib for those that might want
to retrieve the same live image for multiple systems at once without
saturating the network.
This patch requires ctorrent to be installed into initramfs.
Torrent kernel command line format:
root=live:torrent://example.com/liveboot.img.torrent
Start a tracker:
bttrack --bind <tracker_ip> --port 6969 --dfile dstate --reannounce_interval 60
Create the torrent:
ctorrent -t live_image -u http://<tracker_ip>:6969/announce -s live_image.torrent
Seed the initial torrent:
ctorrent live_image.torrent
Boot the live image.
A user can provide a filesystem image (rootfs.img) inside a compressed
tarball and that filesystem image will be mounted read/write. This provides
some benefits over a device mapper snapshot overlay, especially when the
live system becomes full. The boot command line simple needs
"rd.writable.fsimg" added to utilize this feature.
Additional documentation for this option as well as other live boot
options is included.

With the same source of files, it should be possible to generate the
same image file with every dracut run.
To accomplish this, we modify the timestamps of the files we generate at
runtime, call gzip with "-n" and cpio with "--reproducible".
The cpio --reproducible option is not yet upstream though, so if you
feel like it should be then please nag at the cpio mailing list.

DRACUT_PATH can now be used to specify the PATH used by dracut
to search for binaries instead of the default
/usr/sbin:/sbin:/usr/bin:/bin
This should be set in the distribution config file
/usr/lib/dracut/dracut.conf.d/01-dist.conf
because some inst*() functions check the existance of the source files
and do not know about the "-H" option, some failed to install the
hostonly files.
When installing OS to a VLAN enabled iscsi LUN (extracted from iBFT), "/tmp/net.{xyz}.has_ibft_config" is not being set properly.
Then anaconda installer requires 'BOOTPROTO="ibft"' populated in ifcfg of the vlan interface (ex: ibft0.20), for it to properly populate the kernel parameters post installation. The setting 'BOOTPROTO="ibft"' is populated by write-ifcfg.sh script only if the corresponding interface has a file /tmp/net.{xyz}.has_inft_config
To get around this issue, in ibft_to_cmdline() function in net-lib.sh file, I made the following changes to populate the has_ibft_config file for the vlan interface(ex: ibft0.20):
inst* functions and dracut-install now accept the "-H" flag, which
logs all installed files to /lib/dracut/hostonly-files. This is used
to remove those files, if rd.hostonly is given on the kernel command line.
This patch adds option "-m|--mod" to lsinitrd to list dracut
modules in the image because sometimes having an option to
only list the dracut modules in the image could be handy.

lsinitrd (and hence dracut) currently fail to list the contents of any
LZO-compressed image, and merely spit out misleading xzcat errors.
I guess no-one actually uses them.
rd.iscsi.ibft[=1] should be used instead.
Thing is, 'ip=ibft' is not really an ip setting, but rather a marker
that iBFT should be evaluated.
Also removed the trigger of the warning:
"Warning: Please supply bootdev argument for multiple ip= lines"
When a bonded interface is brought up, any slaves included in the bond
have their hardware address set to that of the bond master. Although
this allows an interface to be brought up on start up, when the
configuration file is imported into the booted system it prevents
the bonded interface being successfully restarted.
The fix involves obtaining the hardware address of the slaves before
they are added to the bond and then using this value in the
configuration file.
Currently the block driver detection for generic initrd doesn't include
the SD/MMC drivers so we fail to boot generic images on any device using
those platforms as boot devices when using a generic initrd. Add logic
to detect those modules. This primarily fixes embedded ARM devices but
also likely intel tablets/dev boards and enterprise hypervisors that
have the ability to boot from SD.
Also the ahci_init_controller misses a number of drivers that use the
libahci_platform module for the init so this fixes some missing achi
moduless too.
Finally it cleans up the ARM storage module hacks that the above now
deals with in a more generic manner.

The info message written by require_binaries() was a bit frighten to
users. So just be a little bit more verbose.
If you have ideas on how to improve the message for these "soft"
dependency modules, please submit patches.
It turns out that commit f30b74e (dracut-initqueue service runs before
remote-fs-pre.target) is partial fix for remote fs mounts. Because no
one pulls in remote-fs.target, we can never start remote fs mounts.
Now pull in remote-fs.target in dracut-pre-pivot.

cmdline() prints empty "resume=" options for non-persistent swap

This patch also fixes printf formatting and removes unused variables.
Without the 59-scsi-sg3_utils.rules udev-rule a couple of devices are missing
in /dev/disk/by-id.
If the luks device is specified by-id in /etc/crypttab and rd.luks.uuid not
passed as a commandline parameter during boot, systemd tries to start its
crypto services which depend on those missing devices until it times out and
exits to dracut rescue shell.

By convention, strstr should be a literal string match. Previously, it
would match as a glob pattern. Some code used that, so add new
functions strglob and strglobin to do what that code expects, and
specify them tightly too. strglob tests whether the glob pattern
matches the entire string (the name strglob is also used in the yorick
language, and that's what it does there), while strglobin tests whether
the glob pattern matches anywhere in the string.
Also tightens str_starts, str_ends, and str_replace to deal with
literal strings only. In a quick grep I did not find code that depended
on these functions matching globs.
Changes the call sites where strstr was used with glob patterns to use
strglobin or strglob as the intention seemed to be (or, in one case,
strstr with the * removed as it did not affect the result anyway).

dracut must pull in these remote fs mount and all these remote mounts

Before modifying 69-dm-lvm-metad.rules, we should check for the
existance first. Otherwise this results in error messages on
distributions (debian), which do not ship these rules.
If using systemd in initramfs, we could run into a race condition when
dracut and systemd both are trying to mount and run fsck for the same
filesystem, and mount or fsck could be a failure.
To fix such failure, we should use systemd to mount/fsck from /etc/fstab
only.

Running dracut in a chroot environment, which has /dev not correctly
setup will result in errors like:
/usr/bin/lsinitrd: line 164: /dev/fd/62: No such file or directory
cpio: Malformed number �5�OK��
cpio: Malformed number 5�OK��
cpio: Malformed number �OK��
This is because bash wants /dev/fd/<num> for constructs like:
foo < <$(bar)
It's useful for passing a full fstab line including like fs_passno so fsck
can take effect.
Previously it's assumed that there's no fs_freq and fs_passno in fstab lines
so original code just append "0 0" at the end of each fstab lines.
Improve this issue by assign default value in case they are not passed in.
Three field are handled here:
fs_mntops: default to "defaults"
fs_freq: default to "0"
fs_passno: default to "2"

This caused the root_dev variable not to be set which in turn meant that
the root device was not whitelisted in 99base/module-setup.sh when injecting
compile-time devexists hooks in hostonly initrds. This ties the generated
initrd to the root fs device (typically the UUID) rather than relying solely
only the root= kernel command line.
While it is hostonly, not hardcoding e.g. UUIDs is still desirable. Any
swap partition on the host device is still added however.
The variable that dhclient sets doesn't have dhcp in the name. This
could cause problems with setups where the server is not the same as the
dhcp server.
Add new functions require_binaries() and require_any_binary() to be used
in the check() section of module-setup.sh.
These functions print a warning line telling the user, which binary is
missing for the specific dracut module.
This unifies the way of checking for binaries and makes the life of an
initramfs creator easier, if he wants to find out why a specific dracut
module is not included in the initramfs.
If the root user generates the initramfs image, preserve the ownership
of the files. This of course cannot be done for non-root users
generating an initramfs image.
