[Bug 1114383] chkstat is not always called after Zypper has installed packages
http://bugzilla.suse.com/show_bug.cgi?id=1114383 http://bugzilla.suse.com/show_bug.cgi?id=1114383#c9 --- Comment #9 from Björn Voigt <bjoernv@arcor.de> --- Sorry, the commenters in #c1, #c2, #c3, #c4 and #c5 misunderstood me a bit. I did NOT wrote this bug report to complain about /usr/lib64/libexec/kcheckpass permissions in package kscreenlocker. The kscreenlocker problem was meant as an example for a more general issue with Zypper and chkstat. #c6 pointed this out correctly.
Entries in /etc/permissions.local actually only work reliably for locally installed files like in /usr/local/... that are not managed by zypper. Or for overriding permissions of files that ship with set*id and thus call %set_permissions and %verify_permissions.
I do not think, that it is enough, that single packages call "chkstat --system --set". This may work with the files listed in /etc/permissions /etc/permissions.d/* /etc/permissions.easy /etc/permissions.paranoid /etc/permissions.secure because these files are more or less static and only a limited number of packages are affected. E.g. the files listed in /etc/permissions.easy come from around 40 RPM packages on my TW installation. In theory each of the >=40 packages may call chkstat in postinstall scripts. But Root can list any file in /etc/permissions.local, e.g. files from package A.rpm and B.rpm. During a Zypper run, Zypper can for instance update packages C.rpm and D.rpm. Then it is useless to call "chkstat", if C.rpm and D.rpm does not contain files from /etc/permissions.{easy,paranoid,secure}. But if Zypper updates the packages A.rpm, C.rpm and D.rpm, then Zypper should call chkstat to update the permissions. I find #c7 interesting:
It might work to add
%transfiletriggerin -- / /usr/bin/chkstat --system
to permissions.spec to run chkstat at the end of every transaction.
