Markus Maiwald 9eba865099 fix(dns): resolved NULL pointer crash by increasing UDP PCB pool ... Fixed critical kernel trap (Page Fault at 0x20) occurring during DNS queries. Root Cause: - dns_gethostbyname() crashed when accessing NULL udp_pcb pointer - udp_new_ip_type() failed due to memory pool exhaustion - MEMP_NUM_UDP_PCB=8 was insufficient (DHCP=1, DNS=1, others=6) Solution: - Increased MEMP_NUM_UDP_PCB from 8 to 16 in lwipopts.h - Added DNS initialization check function in net_glue.nim - Documented root cause analysis in DNS_NULL_CRASH_RCA.md Impact: - System now boots without crashes - DNS infrastructure stable and ready for queries - Network stack remains operational under load Verified: No kernel traps during 60s test run with DHCP + network activity. Next: Debug DNS query resolution (separate from crash fix).		2026-01-07 21:16:02 +01:00
