[PATCH v3 0/1] MR4107: wbemprox: Use correct string id.
by eric pouech (＠epo) 17 Oct '23

17 Oct '23

Don't use hard coded string indexes as one of the expected string can be absent, hence decreasing its index; nothing ensures that the strings are placed in the order of the fields in the smbios structure. So use, smbios structures' indexes instead. Wbemprox was also expecting one string too much.

Like I said, Wine is not a regular application, it's just the middle layer between the Unix OS and Windows applications. Your proposal doesn't achieve systemd's goal because you can run multiple applications on Wine which would still get the same ID (even if run in different prefixes). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4108#note_49001

IMO there's no difference in privacy concerns between hardware ID and software ones (some BIOS:es allow you to change the HW id, so the boundary between HW or not is also not that clear). The point is what they identify. what are your concerns about following systemd recommandations? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4108#note_48998

[PATCH 0/3] MR4127: dwrite: Clang warning fixes
by Jacek Caban (＠jacek) 17 Oct '23

This fixes -Wenum-conversion warnings (enabled by default on clang) and -Wpointer-sign warnings (enums are signed on MSVC target, so their pointers should not be implicitly converted to `unsigned int *`). -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4127

Right, and macOS also exposes a hardware ID. Windows/Mac applications should be equally careful with that information. I don't think exposing /etc/machine-id is at the same level though. It's not a hardware ID and you can change it. If privacy is a concern when running Windows applications an alternative would be to sandbox Wine and give it its own machine ID. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4108#note_48991

[PATCH 0/2] MR4108: Improve DMI tables under Linux.
by eric pouech (＠epo) 17 Oct '23

17 Oct '23

This MR improves Wine's DMI tables by: - no longer exposing /etc/machine-id content. Current documentation of systemd strongly suggests to use a hash of it (with app dedicated key). (1) - generates DMI entries for files that are no longer user readable on Linux (like bios serial number). The values are derived from hashed value in step #1. (1) current implementation integrates into unix ntdll a bunch of sha 256 related code. It's basically a reimplementation of libsystemd's sd_id128_get_machine_app_specific(). We could alternatively dynamically link to libsystemd.so. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/4108
