2014-11-28treewide: no need to negate errno for log_*_errno()Michal Schmidt
It corrrectly handles both positive and negative errno values.
2014-11-28treewide: auto-convert the simple cases to log_*_errno()Michal Schmidt
As a followup to 086891e5c1 "log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers", use sed to convert the simple cases to use the new macros: find . -name '*.[ch]' | xargs sed -r -i -e \ 's/log_(debug|info|notice|warning|error|emergency)\("(.*)%s"(.*), strerror\(-([a-zA-Z_]+)\)\);/log_\1_errno(-\4, "\2%m"\3);/' Multi-line log_*() invocations are not covered. And we also should add log_unit_*_errno().
2014-11-24cryptsetup: default to no hash when keyfile is specifiedZbigniew Jędrzejewski-Szmek
For plain dm-crypt devices, the behavior of cryptsetup package is to ignore the hash algorithm when a key file is provided. It seems wrong to ignore a hash when it is explicitly specified, but we should default to no hash if the keyfile is specified. https://bugs.freedesktop.org/show_bug.cgi?id=52630

2014-10-24cryptsetup: Fix timeout on dm device.Hugo Grostabussiat
Fix a bug in systemd-cryptsetup-generator which caused the drop-in setting the job timeout for the dm device unit to be written with a name different than the unit name. https://bugs.freedesktop.org/show_bug.cgi?id=84409

2014-07-31Reject invalid quoted stringsZbigniew Jędrzejewski-Szmek
String which ended in an unfinished quote were accepted, potentially with bad memory accesses. Reject anything which ends in a unfished quote, or contains non-whitespace characters right after the closing quote. _FOREACH_WORD now returns the invalid character in *state. But this return value is not checked anywhere yet. Also, make 'word' and 'state' variables const pointers, and rename 'w' to 'word' in various places. Things are easier to read if the same name is used consistently. mbiebl_> am I correct that something like this doesn't work mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-passwd "Unlock EncFS"' mbiebl_> systemd seems to strip of the quotes mbiebl_> systemctl status shows mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-password Unlock EncFS $RootDir $MountPoint mbiebl_> which is pretty weird
2014-07-26Always check asprintf return codeKarel Zak
There is a small number of the places in sources where we don't check asprintf() return code and assume that after error the function returns NULL pointer via the first argument. That's wrong, after error the content of pointer is undefined.

2014-06-23cryptsetup: don't add unit dependency on /dev/null devices when it is listed ↵Lennart Poettering
as password file As special magic, don't create device dependencies for /dev/null. Of course, there might be similar devices we might want to include, but given that none of them really make sense to specify as password source there's really no point in checking for anything else here. https://bugs.freedesktop.org/show_bug.cgi?id=75816

2014-06-13cryptsetup: check that password is not nullThomas Hindoe Paaboel Andersen
Beef up the assert to protect against passing null to strlen. Found with scan-build.
2014-04-24Fix keysize handling in cryptsetup (bits vs. bytes)David Härdeman
The command line key-size is in bits but the libcryptsetup API expects bytes. Note that the modulo 8 check is in the original cryptsetup binary as well, so it's no new limitation. (v2: changed the point at which the /= 8 is performed, rebased, removed tabs)
2014-04-24Add more password agent informationDavid Härdeman
Add an (optional) "Id" key in the password agent .ask files. The Id is supposed to be a simple string in "<subsystem>:<target>" form which is used to provide more information on what the requested passphrase is to be used for (which e.g. allows an agent to only react to cryptsetup requests). (v2: rebased, fixed indentation, escape name, use strappenda)

Already split variable assignments before invoking the callback. And drop "rd." settings if we are not in an initrd.
2014-03-06cryptsetup: some fixesLennart Poettering
2014-02-17Extract looping over /proc/cmdline into a shared functionZbigniew Jędrzejewski-Szmek
In cryptsetup-generator automatic cleanup had to be replaced with manual cleanup, and the code gets a bit longer. But existing code had the issue that it returned negative values from main(), which was wrong, so should be reworked anyway.
2014-02-08cryptsetup-generator: auto add deps for device as passwordDave Reisner
If the password is a device file, we can add Requires/After dependencies on the device rather than requiring the user to do so.
2014-01-26cryptsetup: Support key-slot optionChristian Seiler
Debian recently introduced the option key-slot to /etc/crypttab to specify the LUKS key slot to be used for decrypting the device. On systems where a keyfile is used and the key is not in the first slot, this can speed up the boot process quite a bit, since cryptsetup does not need to try all of the slots sequentially. (Unsuccessfully testing a key slot typically takes up to about 1 second.) This patch makes systemd aware of this option. Debian bug that introduced the feature: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=704470
2013-11-06util: unify reading of /proc/cmdlineLennart Poettering
Instead of individually checking for containers in each user do this once in a new call proc_cmdline() that read the file only if we are not in a container.

2013-09-29set IgnoreOnIsolate=true for systemd-cryptsetup@.serviceAndrey Borzenkov
When crypttab contains noauto, cryptsetup service does not have any explicit dependencies. If service is started later manually (directly or via mount dependency) it will be stopped on isolate. mount units already have IgnoreOnIsolate set by default. Set it by default for cryptsetup units as well.

This service was merged with systemd-random-seed-save.service in c35b956d34bbb8bb208e49e45de2c103ca11911c.
2013-09-13cryptsetup-generator: allow specifying options in /proc/cmdlineTom Gundersen
The main usecase for this is to make it possible to use cryptsetup in the initrd without it having to include a host-specific /etc/crypttab. Tested-by: Thomas Bächler <thomas@archlinux.org>
2013-09-13cryptsetup-generator: don't create tmp+swap unitsTom Gundersen
2013-09-11cryptsetup: Retry indefinitely if tries=0 option has been set.Thomas Bächler
When running from initrd, entering a wrong passphrase usually means that you cannot boot. Therefore, we allow trying indefinitely.
2013-08-14systemd-cryptsetup: makes “discard” a synonym for “allow-discards”Ondrej Balaz
systemd-cryptsetup recognizes option 'allow-discards' in /etc/crypttab to enable TRIM passthrough to underlying encrypted device. In Debian this option was changed to 'discard' to avoid hyphen in option name. (see: #648868 and `man crypttab`). [zj: update crypttab(5) too, making "discard" the default.]
2013-07-16cryptsetup: Add tcrypt supportJan Janssen
Tcrypt uses a different approach to passphrases/key files. The passphrase and all key files are incorporated into the "password" to open the volume. So, the idea of slots that provide a way to open the volume with different passphrases/key files that are independent from each other like with LUKS does not apply. Therefore, we use the key file from /etc/crypttab as the source for the passphrase. The actual key files that are combined with the passphrase into a password are provided as a new option in /etc/crypttab and can be given multiple times if more than one key file is used by a volume.

It's polite to print the name of the link that wasn't created, and it makes little sense to print the target.

2013-04-18cryptsetup: ask for password, if key file cannot be accessedHarald Hoyer
If the key file cannot be accessed, we can at least ask for the password.

2013-04-18cryptsetup-generator: add support for rd.luks.key=Harald Hoyer
Also clarify rd.luks.uuid and luks.uuid in the manual. https://bugzilla.redhat.com/show_bug.cgi?id=905683
2013-04-18cryptsetup: set the timeout to 0 by defaultHarald Hoyer
cryptsetup itself has no timeout as default from the beginning. So the default timeout has been "0" from the beginning. https://bugzilla.redhat.com/show_bug.cgi?id=949702
2013-04-05Use initalization instead of explicit zeroingZbigniew Jędrzejewski-Szmek
Before, we would initialize many fields twice: first by filling the structure with zeros, and then a second time with the real values. We can let the compiler do the job for us, avoiding one copy. A downside of this patch is that text gets slightly bigger. This is because all zero() calls are effectively inlined: $ size build/.libs/systemd text data bss dec hex filename before 897737 107300 2560 1007597 f5fed build/.libs/systemd after 897873 107300 2560 1007733 f6075 build/.libs/systemd … actually less than 1‰. A few asserts that the parameter is not null had to be removed. I don't think this changes much, because first, it is quite unlikely for the assert to fail, and second, an immediate SEGV is almost as good as an assert.
2013-04-04cryptsetup-generator: add JobTimeoutSec=0 for the decrypted crypt devicesHarald Hoyer
The password query for a crypto device currently times out after 90s, which is too short to grab a cup of coffee when a machine boots up. The resulting decrypted device /dev/mapper/luks-<uuid> might not be a mountpoint (but part of a LVM PV or raid array) and therefore the timeout cannot be controlled by the settings in /etc/fstab. For this reason this device should not carry its own timeout. Also the encrypted device /dev/disk/by-*/* already has a timeout and additionally the timeout for the password query is set in /etc/crypttab. This patch disables the timeout of the resulting decrypted devices by creating <device-unit>.d/50-job-timeout-sec-0.conf files with "JobTimeoutSec=0".
