Today's commits are a perfect example of that - we've got three commits that might not make flashy headlines, but they're absolutely essential for keeping Linux…
Let's start with the biggest story today - Linus merged in some critical security fixes for the s390 architecture. Now, if you're not familiar with s390, that's IBM's mainframe architecture, and these machines are running some seriously mission-critical workloads out there. The fixes are all about preventing…
What's really interesting here is the attention to detail. The team added something called array_index_nospec to prevent speculative out-of-bounds access when the system looks up which system call to run. Think of it like adding a bouncer at the door who…
