I can confirm this. I had to use the following local policy for now:
"""
module local 1.0;
require {
type nfs_t;
type httpd_t;
class file map;
}
#============= httpd_t ==============
allow httpd_t nfs_t:file map;
"""
Lukas, any word on this? I just ran into this on f28 beta with selinux-policy-3.14.1-19.fc28 while testing git-daemon. I filed a PR in the GitHub repo:
https://github.com/fedora-selinux/selinux-policy-contrib/pull/53
As I mentioned there, I'm not sure whether this works for use with the git-http-backend or not. I haven't had time to test that yet. I'll try to do so, but if anyone else beats me to it that would be great. If anyone has specific AVC's from use with git-http-backend it would be helpful.
I tested with git-http-backend and found that it was not sufficient. I submitted a second pull request which should resolve that issue:
https://github.com/fedora-selinux/selinux-policy-contrib/pull/54
In case it helps with testing, here are f27 and f28 scratch builds with the changes: f27: https://koji.fedoraproject.org/koji/taskinfo?taskID=26382332 (koji) https://src.fedoraproject.org/fork/tmz/rpms/selinux-policy/branch/f27 (git) f28: https://koji.fedoraproject.org/koji/taskinfo?taskID=26384218 (koji) https://src.fedoraproject.org/fork/tmz/rpms/selinux-policy/branch/f28 (git) I've only tested the f28 builds. This message is a reminder that Fedora 27 is nearing its end of life. On 2018-Nov-30 Fedora will stop maintaining and issuing updates for Fedora 27. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '27'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 27 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 27 changed to end-of-life (EOL) status on 2018-11-30. Fedora 27 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
With selinux-policy-3.13.1-283.16.fc27.noarch, getting tons of denied "map" AVCs for git like the following. The following is using git-daemon, though similar errors occur when using /var/www/git and git-http-backend type=AVC msg=audit(1511823417.555:12215): avc: denied { map } for pid=11637 comm="git-upload-pack" path="/var/lib/git/rpms/dahdi-linux-kmod.git/objects/a8/0bdc4ec4bfc14f273b92bfadf46571354a2a0a" dev="md1" ino=112943180 scontext=system_u:system_r:git_system_t:s0 tcontext=system_u:object_r:git_sys_content_t:s0 tclass=file permissive=1 Sidenote: F27 came with lots of these denied "map" AVCs across many applications. Is there some bigger SELinux fix coming, or are these to be dealt with one-by-one?
