@liw Mä oon aina ollut sitä mieltä, että naiset vois mun puolesta dominoida johtotehtävissä. Aina kun ollut naispomo, niin homma ollut paremmin balanssissa, ja saanut keskittyä ei-toksisessa ympäristössä omaan juttuunsa. Pitäisköhän liittyä, ja tuoda tämä tuon yhdistyksen agendalle!
Kattoo Suomen talouslukujakin niin kyllähän kaikki menny päin helvettiä, kun saatu rinkirunkkausporukka ruoriin.
Kyllähän eka CEO:kin oli nainen, kun aattelee antiikin kreikkaa. Miehet vaan toimitti tyhjää ja juopotteli :-)

@vbabka lol going there has been like a "dark secret" for me, feels like i was doing something nasty :D but tech is tech for me and i'm interested on everything in tech, even blockchains (as a tech, not a vehicle to make profit), so i don't see anything wrong in it.
you can be critical about stuff (like i'm a bit critical on some aspects of rust) without overlooking into it.

I think this is quite good middle ways with enabling HMAC by default: https://lkml.org/lkml/2024/5/21/583

jarkkoI’d like to switch A-subkey from RSA to ECDSA one. Do I just send the public key via email to helpdesk@kernel.org?

@Tutanota My email provider is non-profit organization #Kapsi from Oulu, Finland. It is full shell access (SSH) with 50GB of backed up space and 500GB of dump storage (not backed up). And the servers are within the homeland borders :-) It is essentially a full no compromises account. There's also opt-in services like MySQL (not using tho). The whole package costs me 40 EUR per year. Cannot get over how great it is and has been :-) Oulu is the town where IRC protocol was invented by Jarkko Oikarinen in 1988 and the first IRC server ever turned on.

Took six review rounds to get it but learned something pretty basic about #BuildRoot: pure dependencies should not have Config.ih{.host} at all. In my case the main asset is swtpm, which depends on libtpms. Only swtpm has Config.in.host now and libtpms has only libtpms.{mk,hash}.

Time test packaging Rust program for BuildRoot. Need a full system build for testing a pam module in dev (written in rust).

Any ways to trace more like bpftrace way between core_initcall and before init starts? Like somehow e.g. compiling eBPF blobs to vmlinux or similar.
I use bootconfig and boot-time tracing stuff and it is nice but barely shadow of what you can do with e.g. bpftrace.

Made my first post to rust-for-linux list given a pratical need and use.
I'll make a PoC with asn1rs by simply deleting everything not needed and hammering the rest 🤷 And first in user space and maybe someone with more kernel rust experience can help me out to fit it there.

The use cases are quite trivial really. Want a server to sign x509 without exposing the private key? Yeah, that's the whole point here. Verification can be done with software, and is done with software. Signing and decryption are done with the private key inside TPM2.
Higher goal is to implement this x509 spec by David Woodhouse but the above is the basic gist here:

v2 of #TPM2 asymmetric keys: https://lore.kernel.org/linux-integrity/20240521031645.17008-1-jarkko@kernel.org/
Crypto stuff is so easy to break especially in format conversions so decided to save low-hanging fruit clean up for a separate version. From this version forward, I'll promise to stop spamming :-)

@securepaul Yeah, not too stressed about that :-) I think I will survive...

@securepaul Good time to activate a bit as I'm on a job seek too. I don't know how to build a great image of myself but I do know how to write code so I guess this is a good approach to move forward ;-)
