This fixes commit 9b0688f Author: Yu Watanabe <[email protected]> Date: Tue Jan 9 10:52:49 2024 +0900 virt: add Google Compute Engine support Signed-off-by: Daniel P. Berrangé <[email protected]> (cherry picked from commit 9ffdfc67c6aedcb66c2b18c2c61bc32e585e6d6e) (cherry picked from commit b077417713ea6df028d61287c042abc235fc0c41)
Currently, IS_SYNTHETIC_ERRNO() evaluates to true for all negative errnos, because of the two's-complement negative value representation. Subsequently, ERRNO= is not logged for most of our own code. Let's fix this, by formatting all synthetic errnos as positive. Then, treat all negative values as non-synthetic. While at it, mark the evaluation order explicitly, and remove unneeded comment. Fixes #33800 (cherry picked from commit 268f58076f7e0258dce75f521d08199092279853) (cherry picked from commit 4ad6b2631d73a574859a62d33715a7bdef810bcf)

The original CVM detection logic for TDX assumes that the guest can see the standard TDX CPUID leaf. This was true in Azure when this code was originally written, however, current Azure now blocks that leaf in the paravisor. Instead it is required to use the same Azure specific CPUID leaf that is used for SEV-SNP detection, which reports the VM isolation type. Signed-off-by: Daniel P.

A PE image's memory footprint might be larger than its file size due to uninitialized memory sections. Normally all PE headers should be parsed to check the actual required size, but the legacy EFI handover protocol is only used for x86 Linux bzImages, so we know only the last section will require extra memory. Use SizeOfImage from the PE header and if it is larger than the file size, allocate and zero extra memory before using it.

Remove an early return that prevents --prompt-root-password or --prompt-root-shell and systemd.firstboot=off using credentials. In that case, arg_prompt_root_password and arg_prompt_root_shell will be false, but the prompt helpers still need to be called to read the credentials.

tcp reset / icmp port-unreachable are markedly different conditions than packet loss. It doesn't make much sense to retry in this case.

We have different impls of detect_confidential_virtualization per architecture. The detection is cached in the x86_64 impl, and as we add support for more targets, we want to use caching for all.

When unit_need_daemon_reload() calls unit_find_dropin_paths() to check for new drop-in configs, the manager's unit path cache is used to limit which directories are considered. If a new drop-in directory is created, it may not be in the unit path cache, and hence unit_need_daemon_reload() may return false, despite a new drop-in being present. However, if a unit path cache is not given to unit_file_find_dropin_paths() at all, then it behaves as if the target path was found in the unit path cache. So, to fix this, adapt unit_find_dropin_paths() to take a boolean argument indicating whether or not to pass along the unit path cache. Set this to false in unit_need_daemon_reload().

The nice value is part of struct sched_attr, and consequently invoking sched_setattr() after setpriority() would clobber the nice value with the default (as we are not setting it in struct sched_attr). It would be best to combine both calls, but for now simply invoke setpriority() after sched_setattr() to make sure Nice= remains effective when used together with CPUSchedulingPolicy=.
