- Replace getopt with manual arg parsing to avoid GNU getopt permutation issues - Add BD_ADDR format validation (rejects malformed addresses instead of segfaulting) - Add bounds checking on all numeric options (-s, -t, -d, -n) - Detect and report extra positional arguments with hint to use -i - Add complete usage text with option descriptions and examples - Add -h flag for help - Rename stat() to sigint_handler() to avoid POSIX name collision - Build with -no-pie to work around i686 PIE stack corruption bug in glibc Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Tested l2flood against K07 Bluetooth speaker. Key finding: the actual disruption mechanism is ACL link preemption, not CPU overload as the upstream README claims. l2flood blocks reconnection but cannot break existing connections. EMP mode (-R) causes persistent state corruption requiring a full power cycle to recover from. Also documents the i686 PIE stack corruption bug and its fix.

Most consumer Bluetooth devices are discoverable. A standard inquiry scan (bluetoothctl/hcitool) returns the full BD_ADDR directly, making UAP brute-forcing unnecessary. Added a section to the README explaining this and when BBF + Ubertooth is actually needed. Also added hcitool scan fallback in cli.py so bbf no longer hard-exits when ubertooth-rx is missing -- it offers to scan for discoverable devices instead.

EMP mode previously spun silently when connect() failed (e.g., target already connected to another device). Now prints the error on first failure and on every new error type, throttled to every 50th attempt for repeated errors. Reports attempt count on successful reconnect.

Phone reconnected to K07 after stopping l2flood -R without resetting either device. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
