that doesn't sound like an accurate portrayal of the article at all. "Kernel Read-Only Primitive" and "Kernel Write-Only Primitive" are vague, but as far as I can tell, "SWAPGS", "BadIRET", &quo

what the fuck? I specified POSIX alternatives to non-POSIX uses in the code. only one feature, brace expansion, is not POSIX, so I specifically did not recommend its use.

eh, common.sh is a lot more complicated than it could be. example: write_hex() { hex="$1" echo "$hex" | sed -e 's/../&\n/' | while read -r hexbyte; do printf "\\x$h

as usual, popular science reporting is based in fact, but misstates it. there are many flavors, but only five basic tastes. the spicy sensations you refer to are touch senses: it is well known that capsaicin spiciness can be felt on most sk

you'd get worse results, because 1) most of those instructions are slower on modern hardware anyways, and 2) assembly is an optimization barrier on modern compilers, so even if you make one function 0.1% faster, it's not worth it

this is utter nonsense. in C, since before C89, all non-zero values are considered true in conditional contexts (if, for, while, ?:). http://port70.net/~nsz/c/c89/c89-draft.html#3.6.4.1 . false must therefore

it could be faster with a hardware chacha20 implementation. if wireguard gets really popular, we might see that eventually. I'd wager a guess that we would get hardware wireguard first though, with fast path acceleration, similar to

the PoC can be optimized: after way too much googling, I finally found a way to consume an arbitrary number of non-empty lines without using any special characters. ironically, it uses perl. perl -00 -ne exit unfortunately, the fir

IIRC, some init implementations have this capability. I'm not saying that it's good in general, but just that it facilitates this particular case.

this article is oddly really knowledgeable and also really unknowledgeable at the same time. despite its length, it doesn't explain what an initramfs is or how it's created until basically the end (excluding the appendix). an init

systemd makes it the most easy. all you need is systemctl switch-root ROOT. on other inits, you usually need to replace /sbin/init, then use some non-portable (sysvinit is not the only competitor) method of telling init to re-ex

It is not only guaranteed by the POSIX standard, as pointed out by the siblings, it is necessary for standard shell scripting idioms to work, e.g. "command1 2>&1 | command2".

This argument confuses and saddens me. If I give away free food which I and others know to be contaminated with foodborne pathogens, is it wrong for them to criticize it? What if I don't know, but I obtain it from a supplier which is k

oh, and of course if you count the vdso as "making a syscall", then three: page fault, polling, and reverse polling.

actually, Linux uses at least two of these: for security reasons (ASLR), the vsyscall page is implemented on modern kernels by unmapping the page, trapping the page fault, and emulating the system call. the recently introduced io_uring inte

By my reckoning, as long as the modem has no public- or customer-facing IP address, it's probably not going to be a vector for easy attacks. It might be accessible from within the ISP network, but if someone has access there then they
