SD and eMMC devices are widely present on Linux systems and became on some products the primary storage medium. One of the key feature for storage is the speed of the bus accessing the data.
Since the introduction of the original “default” (DS) and “high speed” (HS) modes, the SD card standard has evolved by introducing new speed modes, such as SDR12, SDR25, SDR50, SDR104, etc. The same happened to the eMMC standard, with the introduction of high speed modes named DDR52, HS200, HS400, etc. The Linux kernel has obviously evolved to support these new speed modes, both in the MMC core and through the addition of new drivers.
This talk will start by introducing the SD and eMMC standards and how they work at the hardware level, with a specific focus on the new speed modes. With this hardware background in place, we will then detail how these standards are supported by Linux, see what is still missing, and what we can expect to see in the future.

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
- These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

建構嵌入式Linux系統於SD Card
1. Embedded System on SD
Vincent Chen

2013-09-18
2. Motivation
Typically, most embedded systems load system from NAND flash on the target
device. That means the boot loader, kernel and file system are fused on the NAND
flash.
However, in the beginning stage of implementation, the NAND flash is totally empty,
which means, at least, we have to fuse boot loader into the NAND flash, and then
fuse kernel and file system to bring up the system.
To fuse the boot loader into NAND flash is not easy as just copy a file. We have to
use specific tools like chip programmer or JTAG. Some of these tools are
expensive or not easy to get. Users also need to wait patiently while programming
a NAND flash because it takes time. Frequently programming NAND flash also
impacts its endurance due to its physical character. Thus, if we can find a way to
build a system on other external storage device, like SD card, it would be save a lot
of time, cost, and even NAND flash life cycle.

6. Purpose
- Build the embedded system on SD card
- Loading system from SD card completely without NAND flash support.
- The file system on SD card supports read and write facility.
- Implement a utility to fuse boot loader, kernel and file system to SD card easily.
Replace boot from NAND
Load u-boot
Loader Kernel
Load File system
File system readable / writable
7. Benefits
- System is easy to recover/update
just simply replace the SD card.
- Cost down
NAND/NOR flash become optional, not a necessary component anymore.
It saves BOM cost.
- Product in test stage
Modify/update codes easily.
- Multi-OS in one device
Switch OS among different SD cards.
9. How …
To achieve system on SD card, we will face the following issues,
- CPU supports boot from SD card. How does it work?
- An embedded system has three parts: u-boot (boot loader), kernel and file system.
We have to know the exact position in SD card.
- SD card has SDSC (Standard-Capacity), SDHC (High-Capacity) and SDXC
(eXtended-Capacity.) Does all of them can be supported by CPU?
- How to make the boot loader loads kernel and than kernel loads file system
exactly?
34. Fusing Tool
To fuse the boot loader (u-boot.bin), kernel (zImage), and file system (rootfs.tar) to
SD card automatically.
sdcard=$1
if [ "$sdcard" = "" ];then
echo " # Usage - ./sd.sh /dev/SDcardDevicename (ex. sd.sh /dev/sdc)"
echo " # prepare the necessary files(zImage,rootfs.tar,uboot.bin
rootfs.tar is a tar.bz2 file)"
echo " # and verify that the device is correct"
exit 0
.
mkdir /mnt1
mount ${sdcard}2 /mnt1
tar -jxvf rootfs.tar -C /mnt1
cp -rap /mnt/rootfs/* /mnt1
umount /mnt1
rm -rf /mnt1
35. How to use the fusing tool
root@Linux:~# ./sd4.sh /dev/sdc
1. Run the shell script “sd4.sh” as root.
2. Assign the block device where the SD card exists (ex. /dev/sdc).
3. The root file system has to be packed as rootfs.tar before running this shell
script.
4. The boot loader (u-boot.bin), kernel (zImage) and the file system (rootfs.tar)
must exist in the same folder.
5. The name of the files u-boot.bin, zImage, and rootfs.tar are fixed, casesensitive.
36. How the shell script works
step
command
1. Check the device user enters exists and make sure it is an SD card.
2. Partition the device (two partitions will be made).
fdisk
3. Format the second partition as ext3.
mkfs.ext3
4. Fuse the first 8k of u-boot.bin to the BL1 area of the SD card.
dd
5. Fuse the u-boot.bin to the BL2 area of he SD card.
(u-boot.bin has to be smaller than 256KB)
dd
6. Fuse the zImage to the kernel area of he SD card.
dd
7. Make a directory named /mnt1 as the mount point
mkdir
8. Mount the second partition (ext3) to the mount point (/mnt1).
mount
9. Extract rootfs.tar to /mnt1
Tar
10. Un-mount the mount point (/mnt1)
umount
11. Delete the mount point (/mnt1)
rm
