* logd: throttle SELinux denials to 20/secNick Kralevich2014-11-193-22/+13
| | | | | | | | | | | Impose a limit of 20 selinux denials per second. Denials beyond that point don't add any value, and have the potential to cause crashes or denial of service attacks. Do some other misc cleanup while I'm here. Bug: 18341932 Change-Id: I6125d629ae4d6ae131d2e53bfa41e1f50277d402

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initial commit for an audit daemon that writes kernel audit messages to the Android logger. The daemon searches dmesg for all lines that contain "audit" and writes them. Then receiving the messages from the netlink socket. It also formats the messages so they are compatable with ausearch (type=<t> <m> format) Modified: Mark Salyzyn <salyzyn@google.com> - do not start auditd - merge into logd, stripping unnecessary file logging. - Convert headers and code to support C++ - Fix bugs in libaudit - squash timestamp (replace with 0.0) due to duplication - squash pid due to duplication - squash comm due to duplication Change-Id: I421bcf33e7e670d596628b1b5c7c25536ce2d3fe
