This is how I manage my pull requests ATM (creating and pushing signed tags, request-pull etc.):

I’m happy with the tiny jq based templating engine for moustache templates. Has worked surprisingly well.

I've been fine-tuning the policy and caching engine in tpm2sh a lot and next version will allow to:

1. View policy as an expression via 'tpm2sh memory -p <handle>'
2. Create primary keys with arbitrary policies (was not just done nothing special in it).
3. Creating, viewing and maintaining policies for persistent keys.

These sort of come as "side-effect" of just cleaning up and polishing the groundwork :-)

What are known good workarounds with systemd-creds for situations like this:

I can admit that I don't really know what I'm doing ATM :-)

tdf is superb with e.g. Intel SDM, ACPI and TCG specs :-)

OpenAI says dead teen violated TOS when he used ChatGPT to plan suicide.

what the fuck is youtube offering to me

one aspect in security, which has been wrong even in some of the linux foundations pages from time to time is that they differentiate answers between "incorrect password" and "acount does not exist". this should be obviously opaque.

it allows to query which sites user has an account, which is useful information in wrong hands already.

#infosec #oracle

when it comes to infosec i'm glad at least that the "era of silly security questions" is over.

it was super-frustating to copy-paste set-and-forget one-time pad answers to questions such as "what was your mothers maiden name", when they were still a thing.

i don't know who invented them but the person should get some kind of worst invention of IT ever award or something.

Next thing I'll add to tpm2sh is direct support for keyctl syscall and key re-creation in kernel. After that I can revisit asymmetric keys kernel patch set :-)

for what is worth here's arch installation running for my Ryzen 9950X desktop :-)

https://git.kernel.org/pub/scm/linux/kernel/git/jarkko/sysdarch.git/

Just though to upload it somewhere for backup.

It has secure boot (sbctl), TPM2 unlock, and finally EXT4, which is probably a twist from current standards (but is so convenient given universal support everywhere).

rust learning of today: to avoid integer overflows when summing up lengths, always use checked_add in such situations :-)

E.g., this is wrong:

    let total_body_len =
        handle_area_size + parameter_area_size_field_len + param_area_size + sessions_len;

And this is right:

    let total_body_len = handle_area_size
        .checked_add(parameter_area_size_field_len)
        .and_then(|len| len.checked_add(param_area_size))
        .and_then(|len| len.checked_add(sessions_len))
        .ok_or(TpmProtocolError::IntegerTooLarge)?;

Heh, Amazon's satellite internet service launched yesterday and their first marketing angle is “how about you get your AWS Direct Connect over satellite instead of paying for cross connects”

Here is my Ukraine peace proposal:

1. Putin is sent to The Hague.
2. Russian soldiers leave Ukraine including Crimea.
3. Russia returns all kidnapped Ukrainian children.
4. Russia releases all Ukrainian prisoners.
5. Russia pays damages for everything their war has destroyed.
6. Russia pays damages to Ukrainian families who have lost family members.
7. Russia pays damages to every person who has been tortured, abducted or otherwise criminally mistreated.
8. Ukraine becomes a member of the EU.

the main problem with confidential computing is and will be that it is not hacker enabled ecosystem.

or it's as hacker enabled as IBM mainframes.

i.e., there is no such thing as distruptive innovation.

it might be commercially viable story for companies that produce the hardware to other big companies but it is still a sad story ;-)

and you do not own the hardware EVEN if you buy it because it's locked in to the CPU companies CA.

This screenshot shows strong evidence of:

1. OpenSSL cross-compatibility.
2. tpm2-tools cross-compatibility.
3. Linux kernel compatibility (as in trusted keys and in future also asymmetric keys).

in kernel testing i've moved from qemu to "libvirt + qemu" :-) why i haven't done this before...

As of tpm2sh 0.15.14 my microecosystem :-)

#linux #tpm #rustlang

In tpm2sh 0.15.14 TPMKey ASN.1 policy engine starts to be actually stable. I've committed into not expanding features up until key and cache management are polished and it starts to deliver results :-)

#linux #tpm #rustlang

the next piece sliced from tpm2sh: https://crates.io/crates/tpm2-vtpm

Still in very early phases. Now my micro ecosystem has:

1. tpm2-protocol
2. tpm2-crypto (software crypto for doing TPM2 related operations like generating encrypted seeds).
3. tpm2-policy-language
4. tpm2-tpmkey
5. tpm2-vtpm

I think what I get right vs. TSS2 etc. that I'm not building a "big SDK" but instead of common sense re-usable components not enforcing architecture or policy.
