According to UEFI spec 2.10 errata A section 7.4.6 "All events from the EFI_EVENT_GROUP_BEFORE_EXIT_BOOT_SERVICES and EFI_EVENT_GROUP_EXIT_BOOT_SERVICES event notification groups as well as events of type EVT_SIGNAL_EXIT_BOOT_SERVICES must be signaled before ExitBootServices() returns EFI_SUCCESS. The events are only signaled once even if ExitBootServices() is called multiple times." So keep track of whether ExitBootServices() has been called, and signal the event group EFI_EVENT_GROUP_BEFORE_EXIT_BOOT_SERVICES only the first time around. EFI_EVENT_GROUP_EXIT_BOOT_SERVICES will only be signalled if ExitBootServices() is going to run to [successful] completion, after which calling it a second time is not possible anyway. So for this case, no special handling is needed. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> |
