- Fix bsc#1204001. Patches are not upstream, and have been picked up and backported from the ML. This is something we usually prefer to avoid, but this is urgent, and the patches looks fine, with high chances for them to be included as they are (and if they're not, we will revisit this, i.e., drop them and re-include the ones that are actually committed) * Patches added: linux-user-add-more-compat-ioctl-definit.patch linux-user-drop-conditionals-for-obsolet.patch linux-user-remove-conditionals-for-many-.patch meson-enforce-a-minimum-Linux-kernel-hea.patch - Improve the output of update_git.sh, by including the list of repos to which we have downstream patches. - Fix: bsc#1202665, CVE-2022-2962 * Patches added: net-tulip-Restrict-DMA-engine-to-memorie.patch OBS-URL: https://build.opensuse.org/request/show/1007904 OBS-URL: https://build.opensuse.org/package/show/Virtualization/qemu?expand=0&rev=735

Various areas of QEMU have a dependency on Linux kernel header
|
|
definitions. This falls under the scope of our supported platforms
|
|
matrix, but historically we've not checked for a minimum kernel
|
|
headers version. This has made it unclear when we can drop support
|
|
for older kernel headers.
|
|
|
|
* Alpine 3.14: 5.10
|
|
* CentOS 8: 4.18
|
|
* CentOS 9: 5.14
|
|
* Debian 10: 4.19
|
|
* Debian 11: 5.10
|
|
* Fedora 35: 5.19
|
|
* Fedora 36: 5.19
|
|
* OpenSUSE 15.3: 5.3.0
|
|
* Ubuntu 20.04: 5.4
|
|
* Ubuntu 22.04: 5.15
|
|
|
|
The above ignores the 3rd version digit since distros update their
|
|
packages periodically and such updates don't generally affect public
|
|
APIs to the extent that it matters for our build time check.
|
|
|
|
Overall, we can set the baseline to 4.18 currently.
