I presented at the Open Source Summit Korea in Seoul this morning.

10 years ago today, I completed the LFD420 training by The Linux Foundation.

16 years ago today, after watching a presentation on YouTube titled “Write and Submit your first Linux Kernel Patch” by Greg Kroah-Hartman, I submitted my first patch1 to the Linux kernel.

Today I woke up to the great news that we now have “only” 100 -Wflex-array-member-not-at-end issues left to be addressed in linux-next.

While reviewing one of the patches sent to the linux-hardening list this afternoon, I spotted a bug I introduced in the same code two years ago (on March 5 2024, to be precise).

I talked for more than two hours (135 mins to be precise) about upstream Linux kernel hardening at Okayama University this afternoon.

First kernel patch of 2026 addressing 2,600 -Wflex-array-member-not-at-end warnings at once: [PATCH v2][next] ipv4/inet_sock.h: Avoid thousands of -Wflex-array-member-not-at-end warnings It has been taken into the net-next tree and it’s now in linux-next.…

I had a great time at Open Source Summit and Linux Plumbers Conference in Japan last December.
