[PATCH] apparmor: Add support for local profile customizations
by Jim Fehlig 30 Jun '23

30 Jun '23

Apparmor profiles in /etc/apparmor.d/ are config files that can and should be replaced on package upgrade, which introduces the potential to overwrite any local changes. Apparmor supports local profile customizations via /etc/apparmor.d/local/<service> [1]. This change makes the support explicit by adding libvirtd, virtqemud, and virtxend profile customization stubs to /etc/apparmor.d/local/. The stubs are conditionally included by the corresponding main profiles. [1] https://ubuntu.com/server/docs/security-apparmor See "Profile customization" section Signed-off-by: Jim Fehlig <jfehlig(a)suse.com> --- This patch was inspired by an internal bug report. The SUSE libvirt package has marked /etc/apparmor.d/<some-libvirt-service> profiles as 'config(noreplace)' for as long as I can remember. On rare occasions a profile receives a change that is required to avoid regression. And on rarer occasions a user might have made local customizations to the profile. With 'noreplace', the trap is set for the user to experience the regression. Unless other apparmor users convince me otherwise, I'm planning to make this change in the SUSE package, along with changing the main /etc/apparmor.d/ profiles to 'config' and using 'config(noreplace)' for the local customizations only. Note: I'm fine keeping this as a downstream-only patch if upstream isn't interested in the clutter. src/security/apparmor/meson.build | 12 +++++++----- src/security/apparmor/usr.sbin.libvirtd.in | 3 +++ src/security/apparmor/usr.sbin.libvirtd.local | 1 + src/security/apparmor/usr.sbin.virtqemud.in | 3 +++ src/security/apparmor/usr.sbin.virtqemud.local | 1 + src/security/apparmor/usr.sbin.virtxend.in | 3 +++ src/security/apparmor/usr.sbin.virtxend.local | 1 + 7 files changed, 19 insertions(+), 5 deletions(-) diff --git a/src/security/apparmor/meson.build b/src/security/apparmor/meson.build index 58b4024b85..02a6d098ad 100644 --- a/src/security/apparmor/meson.build +++ b/src/security/apparmor/meson.build @@ -34,8 +34,10 @@ install_data( install_dir: apparmor_dir / 'libvirt', ) -install_data( - 'usr.lib.libvirt.virt-aa-helper.local', - install_dir: apparmor_dir / 'local', - rename: 'usr.lib.libvirt.virt-aa-helper', -) +foreach name : apparmor_gen_profiles + install_data( + '@0@.local'.format(name), + install_dir: apparmor_dir / 'local', + rename: name, + ) +endforeach diff --git a/src/security/apparmor/usr.sbin.libvirtd.in b/src/security/apparmor/usr.sbin.libvirtd.in index edb8dd8e26..41bdef53ec 100644 --- a/src/security/apparmor/usr.sbin.libvirtd.in +++ b/src/security/apparmor/usr.sbin.libvirtd.in @@ -139,4 +139,7 @@ profile libvirtd @sbindir@/libvirtd flags=(attach_disconnected) { /usr/{lib,lib64,lib/qemu,libexec}/qemu-bridge-helper rmix, } + + # Site-specific additions and overrides.

[PATCH V2 0/3] apparmor: Add support for local profile customizations
by Jim Fehlig 30 Jun '23

30 Jun '23

This is a stab at a V2 of https://listman.redhat.com/archives/libvir-list/2023-June/240219.html That patch was ACKed and committed, but reverted before the 9.5.0 release since it could be problematic with older apparmor 2.x versions still supported by libvirt. Andrea suggested copies of the profiles for apparmor 2.x and 3.x. This series takes that approach, with patch 1 making an identical copy of the src/security/apparmor directory. Patches 2 and 3 then adjust the profiles accordingly. My approach to copying the existing directory does introduce some duplicate files in the tree, but otherwise it's minimally disruptive and will be easy to rip out when upstream libvirt no longer needs to support apparmor 2.x. FYI, so far I've only tested with apparmor 3.x, but I did push the changes to my fork with CI enabled https://gitlab.com/jfehlig/libvirt/-/pipelines/915347878 Thanks for comments/suggestions!

[PATCH] Revert "lxc_fuse: Tell FUSE that /proc/meminfo is nonseekable"
by Michal Privoznik 29 Jun '23

29 Jun '23

After v8.1.0-61-g030faee28d it is no longer necessary to make the /proc/meminfo file nonseekable as our code that fills the file with spoofed values can handle seeking just fine. Previously, `free(1)` was okay with failed lseek(), but this was ages ago and meanwhile the procps project moved to creating a library and moved the file parsing code under an exported function. In attempt to make the function callable multiple times, it can lseek() multiple times and failure to do so is fatal. This reverts commit 766495508650bebd5f4ac23224ecd0a2ee2ca9eb. Resolves: https://gitlab.com/libvirt/libvirt/-/issues/492 Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- Ideally, I'd like to merge this in the time for upcoming release, but I don't insist.

[PATCH] Revert "apparmor: Add support for local profile customizations"
by Jim Fehlig 28 Jun '23

28 Jun '23

As it turns out, apparmor 2.x and 3.x behave differently or have differing levels of support for local customizations of profiles and profile abstractions. Additionally the apparmor 2.x tools do not cope well with 'include if exists'. Revert this commit until a more complete solution is developed that works with old and new apparmor.

[libvirt PATCH] Add <title> and <description> for Network Objects
by K Shiva 28 Jun '23

28 Jun '23

This patch adds new elements <title> and <description> to the Network XML. - The <title> attribute holds a short title defined by the user and cannot contain newlines. - The <description> attribute holds any documentation that the user wants to store. - Schema definitions of <title> and <metadata> have been moved from domaincommon.rng to basictypes.rng for use by network and future objects. Get/Set Public APIs for modifying these elements as well as <metadata> will be added in a subsequent patch.
