Please forgive my limited understanding of SELinux, I may very well have committed grave mis-diagnostisation. The issue (and solution) is hopefully obvious to the maintainer and others with better knowledge of the subject. Lately, I get occasional emerge failures in various packages with messages like: {{snip}} >>> Completed installing binutils-2.22-r1 into /var/tmp/portage/sys-devel/binutils-2.22-r1/image/ strip: x86_64-pc-linux-gnu-strip --strip-unneeded -R .comment -R .GCC.command.line usr/x86_64-pc-linux-gnu/binutils-bin/2.22/gprof usr/x86_64-pc-linux-gnu/binutils-bin/2.22/ld.gold usr/x86_64-pc-linux-gnu/binutils-bin/2.22/ld usr/x86_64-pc-linux-gnu/binutils-bin/2.22/as usr/x86_64-pc-linux-gnu/binutils-bin/2.22/ld.bfd usr/x86_64-pc-linux-gnu/binutils-bin/2.22/size usr/x86_64-pc-linux-gnu/binutils-bin/2.22/objdump usr/x86_64-pc-linux-gnu/binutils-bin/2.22/ar usr/x86_64-pc-linux-gnu/binutils-bin/2.22/strings usr/x86_64-pc-linux-gnu/binutils-bin/2.22/ranlib usr/x86_64-pc-linux-gnu/binutils-bin/2.22/objcopy usr/x86_64-pc-linux-gnu/binutils-bin/2.22/addr2line usr/x86_64-pc-linux-gnu/binutils-bin/2.22/readelf usr/x86_64-pc-linux-gnu/binutils-bin/2.22/elfedit usr/x86_64-pc-linux-gnu/binutils-bin/2.22/nm usr/x86_64-pc-linux-gnu/binutils-bin/2.22/strip usr/x86_64-pc-linux-gnu/binutils-bin/2.22/c++filt usr/lib64/binutils/x86_64-pc-linux-gnu/2.22/libbfd-2.22.so usr/lib64/binutils/x86_64-pc-linux-gnu/2.22/libopcodes-2.22.so usr/lib64/binutils/x86_64-pc-linux-gnu/2.22/libiberty.a ecompressdir: bzip2 -9 /usr/share/binutils-data/x86_64-pc-linux-gnu/2.22/man * Removing /usr/share/doc >>> Setting SELinux security labels /etc/selinux/targeted/contexts/files/file_contexts: line 339 has invalid regex /etc/dovecot(/.*)?*: nothing to repeat * ERROR: sys-devel/binutils-2.22-r1 failed: * Failed to set SELinux security labels. * * Call stack: * misc-functions.sh, line 1290: Called preinst_selinux_labels * misc-functions.sh, line 1129: Called die * The specific snippet of code: * ) || die "Failed to set SELinux security labels." * * If you need support, post the output of `emerge --info '=sys-devel/binutils-2.22-r1'`, * the complete build log and the output of `emerge -pqv '=sys-devel/binutils-2.22-r1'`. * The complete build log is located at '/var/log/portage/sys-devel:binutils-2.22-r1:20121210-074350.log'. * For convenience, a symlink to the build log is located at '/var/tmp/portage/sys-devel/binutils-2.22-r1/temp/build.log'. * The ebuild environment file is located at '/var/tmp/portage/sys-devel/binutils-2.22-r1/temp/environment'. * Working directory: '/var/tmp/portage/sys-devel/binutils-2.22-r1' * S: '/var/tmp/portage/sys-devel/binutils-2.22-r1/work/binutils-2.22' !!! post preinst failed; exiting. !!! FAILED preinst: 1 Hence, I had a look at the offending line in /etc/selinux/targeted/contexts/files/file_contexts and (from looking at the surrounding entries) changed it from /etc/dovecot(/.*)?* system_u:object_r:dovecot_etc_t to /etc/dovecot(/.*)? system_u:object_r:dovecot_etc_t (the '*' was removed). This solves the issue and let's me emerge packages for a while, until some package install puts it back the way it was. I would think new expression matches the same paths, as .* would match anything .*/.* (and so on) matches, but the expressions might be interpreted differently than I expect. I would have thought the original expression would work too, but apparently not. I gather that the entry is generated from /usr/share/selinux/targeted/dovecot.pp from sec-policy/selinux-dovecot, which contains the following line: /etc/dovecot(/.*)?* system_u:object_r:dovecot_etc_t Using grep and informal statistical investigation, this appears to be a unique construct for the dovecot policy; $ grep -a -R '(/\.\*)?\*' /usr/share/selinux/targeted shows only that one entry, while $ grep -a -R '(/\.\*)?' /usr/share/selinux/targeted lists a large number of entries. $ bzgrep -a '(/\.\*)?\*' /var/distfiles/refpolicy-2.20120725.tar.bz2 also shows only the dovecot entry.
