Fix vipw not resuming correctly when suspended
2019-11-11 20:22:49 -06:00

7eca1112fb Fix vipw not resuming correctly when suspended
Closes #185

If vipw is suspended (e.g. via control-Z) and then resumed, it often gets
immediately suspended. This is easier to reproduce on a multi-core system.

root@buster:~# /usr/sbin/vipw

[1]+  Stopped                 /usr/sbin/vipw
root@buster:~# fg
/usr/sbin/vipw

[1]+  Stopped                 /usr/sbin/vipw

root@buster:~# fg
[vipw resumes on the second fg]

The problem is that vipw forks a child process and calls waitpid() with the
WUNTRACED flag. When the child process (running the editor) is suspended, the
parent sends itself SIGSTOP to suspend the main vipw process. However, because
the main vipw is in the same process group as the editor which received the ^Z,
the kernel already sent the main vipw SIGTSTP.

If the main vipw receives SIGTSTP before the child, it will be suspended and
then, once resumed, will proceed to suspend itself again.

To fix this, run the child process in its own process group as the foreground
process group. That way, control-Z will only affect the child process and the
parent can use the existing logic to suspend the parent.

migrate to new SELinux api
2019-10-28 23:40:06 -05:00
Christian Göttsche
cbd2472b7c migrate to new SELinux api
Using hard-coded access vector ids is deprecated and can lead to issues with custom SELinux policies.
Switch to `selinux_check_access()`.

Also use the libselinux log callback and log if available to audit.
This makes it easier for users to catch SELinux denials.

Drop legacy shortcut logic for passwd, which avoided a SELinux check if uid 0 changes a password of a user which username equals the current SELinux user identifier.
Nowadays usernames rarely match SELinux user identifiers and the benefit of skipping a SELinux check is negligible.

b52ce71c27 Add support for a vendor directory and libeconf
With this, it is possible for Linux distributors to store their
supplied default configuration files somewhere below /usr, while
/etc only contains the changes made by the user. The new option
--enable-vendordir defines where the shadow suite should additional
look for login.defs if this file is not in /etc.
libeconf is a key/value configuration file reading library, which
handles the split of configuration files in different locations
and merges them transparently for the application.

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.

2cac079ef4 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.

This also fixes a problem during installation where-in a loop of 'chmod
4755' calls will mostly fail. However, because the last two succeed
(newuidmap/newgidmap), make considers the command to be a success.
Somewhat not-amusingly, configuring shadow with --with-fcaps will cause
installation to fail because the final chmod call is now a failing one.
