anonymouse64 / check-ld-cache-good.sh

Created November 25, 2019 18:12

Script to ensure ld.so.cache is usable and updated

	#!/bin/sh -e

	# save the original LD_LIBRARY_PATH, and unset it to check the cache
	ORIGINAL_LD_LIBRARY_PATH="$LD_LIBRARY_PATH"
	LD_LIBRARY_PATH=""
	export LD_LIBRARY_PATH

	# FINAL_BINARY should be set and exported to what the "real" final executable
	# that's run is so we can check that
	# an alternative would be to always run the "real" final executable immediately

Chromium snap install hook to create private, correct /etc/ld.so.cache

	#!/bin/bash -ex

	# make sure our fake ld.so.cache exists

	echo "snap private ld.so.cache doesn't exist!"
	exit 1
	fi

	# copying the conf dir from real /etc into $SNAP_DATA

anonymouse64 / hashmap.go

Created July 31, 2020 14:26

Hash a map and a bool in Go deterministically

	func hashMapAndBool(b bool, m map[string]string) string {
	h := sha256.New()

	// hashing maps is not deterministic because it is not sorted, so we have
	// to manually hash each key value into another hash after sorting

	// first we hash the string representation of the bool
	h.Write([]byte(fmt.Sprintf("%v", b)))
	keys := make([]string, len(m))
	i := 0

anonymouse64 / sign-system-user-assertion.sh

Created September 25, 2020 10:28

simplistic shell script for creating system-user assertions for use with snapd/ubuntu core

	#!/bin/bash

	set -e

	# first argument is the name of the key to sign the assertion with
	if [ "$#" != 1 ]; then
	echo "usage: ./sign-system-user-assertion <key-name>"
	exit 1
