Pull request overview
This PR makes a series of small robustness and cleanup changes across host interface profiles: centralizing SafeC error handling via ERR_CHK, adding null checks and resource handling, tightening some concurrency patterns, and refining a few behaviors (e.g., event publishing and port selection).
Changes:
- Simplified SafeC
strcpy_serror handling by replacing manualif (rc != EOK)checks with theERR_CHK(rc)macro in many profile handlers (Time, STBService, IP, Ethernet, DeviceInfo, ProcessStatus, IP client handler). - Added defensive checks and cleanup: null-parameter guards (e.g., in
getVirtualInterfaceName,getEthernetInterfaceName), safer inotify setup inXBSStore::getAuthServicePartnerID, more robust process/thread logic inXBSStore::getInstance,executeRfcMgr, WebPA readiness monitoring, and Parodus condition waits. - Tweaked specific behaviors: bounded local port search, corrected RBUS
preValuehandling for download status events, and minor JSON-RPC helper usage updates viastd::move.

notifyKey and notifyValuePtr are allocated, inserted into notifyhash, and then freed at the end of this block (free(notifyKey); free(notifyValuePtr);), even though the GHashTable holds pointers to them for later use. This creates a use-after-free (and likely double-free when the hash table is cleaned up) whenever the notification hash is read or destroyed. These allocations should not be freed immediately after g_hash_table_insert; instead, allow the hash table to own them and free them when notifications are disabled or when the table is destroyed, in line with the comment above.
