2021-03-10 | services: Prevent following symlinks during activation....This addresses a potential security issue, where a compromised
service could trick the activation code in changing the permissions,
owner and group of arbitrary files. However, this patch is
currently only a partial fix, due to a TOCTTOU (time-of-check to
time-of-use) race, which can be fixed once guile has bindings
to openat and friends.
Fixes: <https://lists.gnu.org/archive/html/guix-devel/2021-01/msg00388.html>
* gnu/build/activation.scm: new procedure 'mkdir-p/perms'.
* gnu/services/authentication.scm
(%nslcd-activation, nslcd-service-type): use new procedure.
* gnu/services/cups.scm (%cups-activation): likewise.
* gnu/services/dbus.scm (dbus-activation): likewise.
* gnu/services/dns.scm (knot-activation): likewise.

2019-03-08 | activation: Shared system home directories are now 555 and root-owned....Fixes <https://bugs.gnu.org/34788>.
Reported by Jack Hill <jackhill@jackhill.us>.
Regression introduced by the combination of
8bb76f3d44c1f5ffec8011819494db306a51d801 and
0ae735bcc8ff7fdc89d67b492bdee9091ee19e86: /var/empty would be 700 and
owned by one of the system accounts (thus inaccessible to others), and
/var/run/dbus would be 700 as well, thereby preventing D-Bus clients
from connecting to the daemon.
* gnu/build/activation.scm (duplicates): New procedure.
(activate-users+groups)[system-accounts]: New variable.
Use it. Make shared system account home directories #o555 and
root-owned.
* gnu/services/dbus.scm (dbus-activation): Make /var/run/dbus #o755.
* gnu/tests/base.scm (run-basic-test): Test the ownership and
permissions of /var/empty.

[make-home-directory]: New procedure.
Rewrite in terms of 'user+group-databases', 'write-group', etc.

* gnu/system/shadow.scm (account-activation): Remove (setenv "PATH" ...)
expression, which is now unneeded.

procedures.
* gnu/system/shadow.scm (account-activation): Call them in the arguments
to 'activate-users+groups'.
(account-shepherd-service): Likewise.
* gnu/build/activation.scm (activate-users+groups): Expect a list of
<user-account> and a list of <user-group>. Replace uses of 'match' on
tuples with calls to record accessors.
(activate-user-home): Likewise.

2019-03-04 | activation: Make home directories #o700 by default....Until now they'd be #o755, except for /root, which is treated specially
in (gnu build install).
* gnu/build/activation.scm (activate-user-home): Chmod HOME to #o700.
Remove redundant 'unless system?'.
