e293aa9cfc Honor --sbindir and --bindir for binary installation
Some distros don't care about the split between /bin, /sbin, /usr/bin,
and /usr/sbin, so let them easily stuff binaries wherever they want.

edf7547ad5 Fix failing chmod calls on installation for suidubins
suidubins should be suidusbins, since these binaries are installed
${prefix}/sbin. This historically hasn't broken the build because
chmod of newgidmap/newuidmap succeeds, causing make to think the command
succeeded. Configuring shadow with --with-fcaps removes these final two
entries and exposes the chmod failure to make.

Fix formatting of login.defs comments. Variables are preceeded by "#"
without space, comments are preceeded by "# ". It makes the file machine

A configure error occurs when /bin/sh -> dash:
  checking for is_selinux_enabled in -lselinux... yes
  checking for semanage_connect in -lsemanage... yes
  configure: 16322: test: yesyes: unexpected operator

Use "=" instead of "==" since dash doesn't support this operator.

c1d36a8acb Add support for btrfs subvolumes for user homes
new switch added to useradd command, --btrfs-subvolume-home. When
specified *and* the filesystem is detected as btrfs, it will create a
subvolume for user's home instead of a plain directory. This is done via
`btrfs subvolume` command.  Specifying the new switch while trying to
create home on non-btrfs will result in an error.

userdel -r will handle and remove this subvolume transparently via
`btrfs subvolume` command. Previosuly this failed as you can't rmdir a
subvolume.

usermod, when moving user's home across devices, will detect if the home
is a subvolume and issue an error messages instead of copying it. Moving
user's home (as subvolume) on same btrfs works transparently.

Merge pull request #164 from t8m/use-lckpwdf
Use lckpwdf() again if prefix is not set and fix a possible DoS in locking
2019-05-03 10:43:41 +02:00
Tomas Mraz
64d7688acb Do not fail locking if there is a stale lockfile.
As the lockfiles have PID in the name, there can be no conflict
in the name with other process, so there is no point in using
O_EXCL and it only can fail if there is a stale lockfile from
previous execution that crashed for some reason.

408b8a5482 Use the lckpwdf() again if prefix is not set
The implementation of prefix option dropped the use of lckpwdf().
However that is incorrect as other tools manipulating the shadow passwords
such as PAM use lckpwdf() and do not know anything about the
shadow's own locking mechanism.

This reverts the implementation to use lckpwdf() if prefix option
is not used.

fe34a2a0e4 Make the sp_lstchg shadow field reproducible (re. #71)
From <https://github.com/shadow-maint/shadow/pull/71>:

```
The third field in the /etc/shadow file (sp_lstchg) contains the date of
the last password change expressed as the number of days since Jan 1, 1970.
As this is a relative time, creating a user today will result in:

username:17238:0:99999:7:::
whilst creating the same user tomorrow will result in:

username:17239:0:99999:7:::
This has an impact for the Reproducible Builds[0] project where we aim to
be independent of as many elements the build environment as possible,
including the current date.

This patch changes the behaviour to use the SOURCE_DATE_EPOCH[1]
environment variable (instead of Jan 1, 1970) if valid.
```

This updated PR adds some missing calls to gettime (). This was originally
filed by Johannes Schauer in Debian as #917773 [2].

5b41b7d1b1 usermod: Guard against unsafe change of ownership of home directory content
In case the home directory is not a real home directory
(owned by the user) but things like / or /var or similar,
it is unsafe to change ownership of home directory content.

The test checks whether the home directory is owned by the
user him/herself, if not no ownership modification of contents
is performed.
