=== DF-0035 unprivileged sanity check on PATCHED #1 kernel (2026-07-02) ===
Kernel: DragonFly 6.5-DEVELOPMENT #1: Thu Jul  2 14:31:15 UTC 2026
Run as: maxx (uid 1001, not in wheel)
Tool:  msgbuf_diag 50000 1048576   (50000 sysctl kern.msgbuf reads, oldlen 1MiB)

[*] kern.msgbuf natural length = 8735 bytes
[*] polling 50000 times with oldlen=1048576 ...
[*] 50000 sysctl reads in 1.20s (41506/s)
[*] max returned length observed: 8735 bytes
[*] reads > MSGBUF_UPPER_BOUND (2097152): 0
[*] reads > natural length: 0
[*] reads with suspect non-text tail: 0
[*] RESULT: no OOB observed this run

Conclusion: normal unprivileged kern.msgbuf reads are unaffected by the fix —
they return the natural boot-log length with no over-long / OOB reads.
