Sliding window limits each UID to 2 hardware generateKey calls per
30s burst window with max 2 concurrent. Overflow falls back to
software cert generation.
importKey post-hook retains patched chains instead of full eviction,
preventing detectors from using generate-then-import to bypass
attestation patching. getKeyEntry serves retained chains for imported
keys that overwrote attested aliases.
Some upstream keybox sources inject HTML comments inside PEM
certificate blocks. BouncyCastle's PEMParser chokes on these
non-base64 lines, silently failing to load the keybox.
Filter lines starting with <!-- in trimLines() before the content
reaches the PEM parser.
Individual thread crashes silently kill the thread without bringing
down the process. The half-dead process stays alive but broken, and
the service.sh restart loop never fires.
Install a default uncaught exception handler that logs the error and
calls exitProcess(0), triggering the restart loop for full recovery.
When a config file is deleted, the event handler sets file=null but
then force-unwraps it with file!! in the when block, crashing the
FileObserver thread. All subsequent config change notifications are
silently lost.
Replace force-unwrap with safe call, log a warning on deletion.
When the Java interceptor process dies, callback->transact() returns
DEAD_OBJECT but the code fell through to the real keystore, exposing
genuine TEE state to requesting apps.
Add pingBinder() liveness check on pre-transact failure. If the
interceptor is confirmed dead, return DEAD_OBJECT to the caller
instead of forwarding to real hardware. Apps see a transient service
error rather than the actual device attestation state.
