logd: refine permissions to access /data/system/packages.list Refine DAC security surrounding logd.daemon worker thread and add a positive test for logd failure to access /data/system/packages.list. - Add AID_PACKAGE_INFO to groups of worker thread. - Move AID_SYSTEM to groups, setgid to AID_LOGD. - Do not drop capabilities until after setting the uid and gids. - Add a test that is part of logd.statistics test to check when packagelistparser appears broken. - If /data/system/packages.list is encrypted, ensure we do not pick up the existing inode to ensure strong positive when finding access problems. - Replace all occurrences of NULL with nullptr in gTest code for compliance with best practices. Test: gTest logd-unit-tests --gtest_filter=logd.statistics (expect consistent failure, later CLs fix) Bug: 37751120 Bug: 36645158 Change-Id: I01b26fe5e25203246ae432d272c8daa9c07cab54

logd: add getEventTag command and service Will register a new event tag by name and format, and return an event-log-tags format response with the newly allocated tag. If format is not specified, then nothing will be recorded, but a pre-existing named entry will be listed. If name and format are not specified, list all dynamic entries. If name=* list all event log tag entries. Stickiness through logd crash will be managed with the tmpfs file /dev/event-log-tags and through a reboot with add_tag entries in the pmsg last logcat event log. On debug builds we retain a /data/misc/logd/event-log-tags file that aids stickiness and that can be picked up by the bugreport. If we detect truncation damage to /dev/event-log-tags, or to /data/misc/logd/event-log-tags, rebuild file with a new first line signature incorporating the time so mmap'd readers of the file can detect the possible change in shape and order. Manual testing: Make sure nc (netcat) is built for the target platform on the host: $ m nc Then the following can be used to issue a request on the platform: $ echo -n 'getEventTag name=<name> format="<format>"\0EXIT\0' | > nc -U /dev/socket/logd Test: gTest logd-unit-test --gtest_filter=getEventTag* Bug: 31456426 Change-Id: I5dacc5f84a24d52dae09cca5ee1a3a9f9207f06d
