I noticed a microcode update which was expected, but there's also been firmware updates for Intel WiFi cards - which I wasn't expecting.
I don't suppose anyone can comment on why the WiFi update?
- AnssiH 9y agoAMD CPU microcode is contained in the linux-firmware package/repository ( https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/amd-ucode https://git.kernel.org/pub/scm/linux/kernel/git/firmware/lin... ) which also contains Intel WiFi card firmware. So if your Linux distribution provides a new release of linux-firmware package, you may get new versions of WiFi firmware packages as well with no actual changes to those. This seems to be the case with at least RHEL: https://access.redhat.com/errata/RHSA-2018:0015 https://access.redhat.com/errata/RHSA-2018:0015 The RHEL linux-firmware update contains an AMD microcode update that involves Spectre mitigations. AMD microcode is mentioned at https://access.redhat.com/articles/3311301 https://access.redhat.com/articles/3311301 and the linux-firmware package changelog says: * Wed Dec 27 2017 Rafael Aquini <aquini@redhat.com> - 20170606-57.gitc990aae - Add amd-ucode for fam17h (Intel CPU microcode is part of microcode_ctl package, updated separately)
- BuildTheRobots 9y agoThank you very much for the response; I didn't realize RHEL would every version-bump a package without anything actually changing! For the sake of my own sanity, i tested the iwlwifi-1000 firmware package iwl1000-firmware-39.31.5.1-57 and "-58" and can see no changes when hashing the files.
