I’m wondering why in #OpenSUSE #Tumbleweed zypper si -d needs the source package as -d should tell to get only build dependencies, and not the source package.

#TPM integrity protection is almost there:

https://lore.kernel.org/linux-integrity/D0X00LTUCCC8.X8LKLJHZZRGP@kernel.org/#t

Those are my only remaining remarks for v8.

The idea is that HMAC pipe is used for communication derived from null seed (which changes each power cycle). If the integrity is compromised access to the TPM device will be denied.

I still need to figure out the negative testing. This series has been already tested when machine works as expected and the bus is not compromised.

Combined with TPM2 sealed hard drive encryption should be quite reasonable way to secure a system (of course nothing never is perfect).

Kernel man page generation: is that acceptable for the official linux man pages? I should put out SGX man pages at some point (has been in queue for 2 years) but using troff is not something I can say that I enjoy doing.

I.e. there is man page generation instructions here: https://www.kernel.org/doc/html/latest/doc-guide/kernel-doc.html

Alastair captures one of the biggest problems with the current RISC-V spec. When I looked into this a while back I was (almost) shocked at the lack of rigor and state of the tooling. I say almost because I expected it, but was still sad. Read his blog.

Incredible research at BlackHat Asia today by Tong Liu and team from the Institute of Information Engineering, Chinese Academy of Sciences (在iie.ac.cn 的电子邮件经过验证)

A dozen+ RCEs on popular LLM framework libraries like LangChain and LlamaIndex - used in lots of chat-assisted apps including GitHub. These guys got a reverse shell in two prompts, and even managed to exploit SetUID for full root on the underlying VM!

I think this is the most time-standing IT book that I own. It was published in 1999 and I still check it from time to time.

E.g. when collaborating with hpa on arch/x86/realmode, this book was my main reference in addition to ELF specification.

It is also as prose very nice reading with cool stories embedded!
