D. Andrei Măceș 2540653e36 msm8226-common: init: Modify time_daemon to allow settimeofday() fallback ... The legacy time_daemon binary relied on the old Android alarm dri- ver for setting RTC at bootup. Once /dev/alarm support was removed we found that time cannot be restored properly, unless a data con- nection was available for NTP sync. However, the blob already has a fallback mechanism that relies on settimeofday(), except that it could never work properly. While time_daemon is started under UID/GID of root, it immediately drops to system/net_raw, which is required for subsequent socket commu- ications (e.g., QMI, modem, etc). The issue was that any UID transition from root triggers the remo- val of all thread capabilities, including CAP_SYS_TIME, required for settimeofday() or other RTC adjustments. Thus, time_daemon was edited to skip the internal set[gu]id() calls altoghether, in order to use the new capabilities mechanism introduced with Oreo init.
