[PATCH v1 00/10] move memory module align to PostParse time
by Daniel Henrique Barboza 18 Nov '20

18 Nov '20

Hi, This is a work that I intended to do after pSeries NVDIMM changes I made in commit v6.7.0-302-gd3f3c2c97f. The reasoning is that if ppc64 NVDIMM alignment can be done in PostParse time, regular ppc64 DIMMs alignment can also be done the same way. After that I realized that the same logic can be applied to x86 as well, and then I started to see where we could eliminate explicit align calls. The end result is that a bug that affects pSeries the most was found and fixed in patch 02, and now we're able to reflect the exact memory being used by the guest in the live XML since the alignment is now done in parse time. The series can be fetched from: https://gitlab.com/danielhb/libvirt/-/tree/memory_modules_postparse_v1 NOTE: I worked with the x86 logic based on what I could assert from the code itself, i.e. the aligment mechanics (2MiB align for mem modules, 1MiB align for total memory) are related to QEMU internals, not being hypervisor-agnostic. If someone with authority can guarantee that the alignment restrictions for x86 are applicable to all hypervisors (like in the pSeries case), let me know and I'll respin the series putting the x86 code in virDomainMemoryDefPostParse().

[libvirt PATCH 00/16] docs: add manpages for all the modular daemons
by Daniel P. Berrangé 18 Nov '20

18 Nov '20

Most of the modular daemon stuff has been done from a single template, but for the man pages that is more trouble than it is worth, so we create a separate man page source for each daemon, which makes it easy to extend with driver specific information.

[PATCH 0/5] Deduplicate some of validation code
by Michal Privoznik 18 Nov '20

18 Nov '20

These stemmed from Cole's comment on my patches: https://www.redhat.com/archives/libvir-list/2020-November/msg00888.html The approach might not be that obvious at first because domCaps do qemuCaps to device model translation and during validation we want the exact opposite - we have parsed device model and want to check whether qemuCaps has corresponding capability. But what we can do, is let domCaps code fill a bitmap of supported device models and then check if the bit that corresponds to parsed device model is set. In this series I'm fixing RNG and video models, which were checked this way until very recently (until I touched the code). And also I'm introducing graphics check (which is new) because that one looked the most sane from virQEMUCapsFillDomainCaps(). The rest there not that much. Michal Prívozník (5): domain_capabilities: Introduce VIR_DOMAIN_CAPS_ENUM_IS_SET qemu_validate: Deduplicate code for video model check qemu_validate: Deduplicate code for RNG model check domcaps: Report egl-headless graphics type qemu_validate: Deduplicate code for graphics type check src/conf/domain_capabilities.c | 2 +- src/conf/domain_capabilities.h | 2 + src/qemu/qemu_capabilities.c | 8 +- src/qemu/qemu_capabilities.h | 9 ++ src/qemu/qemu_validate.c | 107 ++++-------------- .../domaincapsdata/qemu_2.10.0-q35.x86_64.xml | 1 + .../domaincapsdata/qemu_2.10.0-tcg.x86_64.xml | 1 + .../qemu_2.10.0-virt.aarch64.xml | 1 + tests/domaincapsdata/qemu_2.10.0.aarch64.xml | 1 + tests/domaincapsdata/qemu_2.10.0.ppc64.xml | 1 + tests/domaincapsdata/qemu_2.10.0.s390x.xml | 1 + tests/domaincapsdata/qemu_2.10.0.x86_64.xml | 1 + .../domaincapsdata/qemu_2.11.0-q35.x86_64.xml | 1 + .../domaincapsdata/qemu_2.11.0-tcg.x86_64.xml | 1 + tests/domaincapsdata/qemu_2.11.0.s390x.xml | 1 + tests/domaincapsdata/qemu_2.11.0.x86_64.xml | 1 + .../domaincapsdata/qemu_2.12.0-q35.x86_64.xml | 1 + .../domaincapsdata/qemu_2.12.0-tcg.x86_64.xml | 1 + .../qemu_2.12.0-virt.aarch64.xml | 1 + tests/domaincapsdata/qemu_2.12.0.aarch64.xml | 1 + tests/domaincapsdata/qemu_2.12.0.ppc64.xml | 1 + tests/domaincapsdata/qemu_2.12.0.s390x.xml | 1 + tests/domaincapsdata/qemu_2.12.0.x86_64.xml | 1 + .../domaincapsdata/qemu_3.0.0-q35.x86_64.xml | 1 + .../domaincapsdata/qemu_3.0.0-tcg.x86_64.xml | 1 + tests/domaincapsdata/qemu_3.0.0.ppc64.xml | 1 + tests/domaincapsdata/qemu_3.0.0.s390x.xml | 1 + tests/domaincapsdata/qemu_3.0.0.x86_64.xml | 1 + .../domaincapsdata/qemu_3.1.0-q35.x86_64.xml | 1 + .../domaincapsdata/qemu_3.1.0-tcg.x86_64.xml | 1 + tests/domaincapsdata/qemu_3.1.0.ppc64.xml | 1 + tests/domaincapsdata/qemu_3.1.0.x86_64.xml | 1 + .../domaincapsdata/qemu_4.0.0-q35.x86_64.xml | 1 + .../domaincapsdata/qemu_4.0.0-tcg.x86_64.xml | 1 + .../qemu_4.0.0-virt.aarch64.xml | 1 + tests/domaincapsdata/qemu_4.0.0.aarch64.xml | 1 + tests/domaincapsdata/qemu_4.0.0.ppc64.xml | 1 + tests/domaincapsdata/qemu_4.0.0.s390x.xml | 1 + tests/domaincapsdata/qemu_4.0.0.x86_64.xml | 1 + .../domaincapsdata/qemu_4.1.0-q35.x86_64.xml | 1 + .../domaincapsdata/qemu_4.1.0-tcg.x86_64.xml | 1 + tests/domaincapsdata/qemu_4.1.0.x86_64.xml | 1 + .../domaincapsdata/qemu_4.2.0-q35.x86_64.xml | 1 + .../domaincapsdata/qemu_4.2.0-tcg.x86_64.xml | 1 + .../qemu_4.2.0-virt.aarch64.xml | 1 + tests/domaincapsdata/qemu_4.2.0.aarch64.xml | 1 + tests/domaincapsdata/qemu_4.2.0.ppc64.xml | 1 + tests/domaincapsdata/qemu_4.2.0.s390x.xml | 1 + tests/domaincapsdata/qemu_4.2.0.x86_64.xml | 1 + .../domaincapsdata/qemu_5.0.0-q35.x86_64.xml | 1 + .../domaincapsdata/qemu_5.0.0-tcg.x86_64.xml | 1 + .../qemu_5.0.0-virt.aarch64.xml | 1 + tests/domaincapsdata/qemu_5.0.0.aarch64.xml | 1 + tests/domaincapsdata/qemu_5.0.0.ppc64.xml | 1 + tests/domaincapsdata/qemu_5.0.0.x86_64.xml | 1 + .../domaincapsdata/qemu_5.1.0-q35.x86_64.xml | 1 + .../domaincapsdata/qemu_5.1.0-tcg.x86_64.xml | 1 + tests/domaincapsdata/qemu_5.1.0.x86_64.xml | 1 + .../domaincapsdata/qemu_5.2.0-q35.x86_64.xml | 1 + .../domaincapsdata/qemu_5.2.0-tcg.x86_64.xml | 1 + tests/domaincapsdata/qemu_5.2.0.x86_64.xml | 1 + 61 files changed, 97 insertions(+), 87 deletions(-) -- 2.26.2

[libvirt] improve security by adjusting the privileges of libvirtd processes
by yebiaoxiang 18 Nov '20

18 Nov '20

Hi Team The daemon libvirtd runs as root user, which against the least privilege security model. root 567642 1.2 0.0 2856020 47576 ? Ssl 15:49 0:02 /usr/sbin/libvirtd --listen In addition, the "--listen" parameter exposes TCP or TLS ports on the network, it increasing the attack surface. tcp 0 0 0.0.0.0:16509 0.0.0.0:* LISTEN 647824/libvirtd tcp 0 0 0.0.0.0:16514 0.0.0.0:* LISTEN 647824/libvirtd I have the following puzzles: 1. Whether root is the least privilege required for libvirtd to manage virtualization platforms, it's possible to run libvirtd as a non-root user? 2. Is there any plan to resolve this security weaknesses? (like move the function of "--listen" to an independent non-root process, or other better schemes) Regards, BiaoXiang
