When it comes time to read that data, the checksum is calculated anew and compared to the stored value if the two match, one can be confident that the data has not been modified (or corrupted by the hardware) since the checksum was calculated.
#ARCHIPEL EJABBERD OPENSSL CODE#
Integrity-verification code at the filesystem or storage level generally works by calculating (and storing) checksums of each block of data.
#ARCHIPEL EJABBERD OPENSSL PATCH#
More Recently, Johannes Thumshirn has posted a patch series adding filesystem-level authentication to Btrfs it promises to provide integrity with a surprisingly small amount of code. Technologies like dm-verity and fs-verity are attempts to solve this problem, as is the recently covered integrity policy enforcement security module. Comments in the patch set say that the TCP-based communication system “is intended for Popcorn testing and development purposes only”, suggesting that, someday, somebody will get around to implementing something better.ĭevelopers who are concerned about system integrity often put a fair amount of effort into ensuring that data stored on disk cannot be tampered with without being detected. There does not seem to be any provision for nodes going up or down or being absent entirely. No sort of authentication is done for incoming node connections, which might seem like a bit of a security issue indeed, the patch set warns against running Popcorn on machines connected to the Internet. There is a hard-coded maximum of 62 nodes. Thereafter, each node is known by an integer ID which is simply its position in the nodes file. Each machine will make a TCP connection to every node listed ahead of itself in this file, then wait for an incoming connection from every node listed afterward. The module reads a list of IP addresses (IPv4 only) directly from a file (/etc/popcorn/nodes by default). Popcorn itself is started by loading a kernel module that is charged with connecting the larger system together. It is an interesting proof of concept, but one should not expect to see it merged in anything close to its current form.Įach node in a Popcorn system is a separate Linux host sitting on the network. The posted code, which is a portion of the larger project, is focused on process migration and memory sharing across machines. This project has, among other goals, the objective of turning a tightly networked set of computers into something that looks like a single system - a sort of NUMA machine with even larger than usual inter-node costs. It is the first appearance on the kernel mailing lists of an academic project (naturally called Popcorn Linux) that has been underway since 2013 or so. The end of April saw the posting of a complex patch set called “Popcorn Linux distributed thread execution”.

The configuration documentation is detailed, but even for a seasoned systems administrator or XMPP guru, a lot of questions remain.

However, to obtain a smoothly running modern feature set is harder. It is easy to get it running for text-based messaging with a few configuration changes. Ejabberd is one of the most widely used XMPP servers.
