How to read pstore/ramoops via mtkclient

Noted for Xiaomi Redmi Note 11S 5G (mt6886, codename: opal).

python mtk.py da peek 0x48090000 0xe0000 --filename pstore.bin
  • Ghidra/strings can be later used to read text inside pstore.bin after peeking

This error might occur durring kernel build. It is happening because newer versions of OpenSSL disallow using SHA-1.

Makes Pi-Hole use second upstream DNS server when the first server fails to complete the request, instead of the default round-robin technique that cycles through the upstream servers to distribute the load. This is a dnsmasq configuration file
