@visegrad24 Deportation is the humane option

🇸🇾🇩🇪 Syria has rejected Germany’s plan to return over 700,000 Syrian refugees to their home country. "We categorically reject any attempts at forced deportation,” said Syrian Foreign Minister Asaad al-Shaibani. He added that Syrians in Germany are a “strategic resource” rather than a burden.

@wedtm @only01Essential At that point just yeet the disclosure onto a public mailing list.

Bro, this is how it works. You don’t get the massive payout that black hats do, but you’re also not looking over your shoulder every night or wearing an orange jumpsuit. Not to mention that the $800m isn’t *theirs*, what money are they going to pay the $250k bounty with? At what point does it flip from a disclosure to extortion?

Meanwhile i saved ecosystem from a massive $800m hack and the team is offering me $4k. Whitehats lose everytime.

@MartinSellner_ Absolut undemokratisch

Ordnungsruf für Remigration Die irren Altparteien wollen verbieten, dass im Nationalrat der Begriff Remigration verwendet wird. Die Hälfte der Österreicher will umfassende Remigration. Die Mehrheit will eine Remigrationspartei wählen. Und im Parlament soll man den Begriff nicht erwähnen dürfen...

@readylayerone @alessandrod Frankendancer has been running XDP for 2 years Agave improved replay quite a lot by copying a bunch of other FD features, like speculative execution (a bit incorrectly hence 4.0 patch releases on mainnet) They have not yet caught up to full FD's performance but still good work

@alessandrod but did validators that run frankendancer turn on xdp on testnet?

I've been critical of them in the past, but wow, this is the biggest frankendancer perf improvement to date. 4 times faster! credit where credit is due, amazing work team! (this is them rebasing on top of agave 4.0 and picking up our perf work for free lol)

@deanmlittle IBT has a 0x3e notrack prefix that disables enforcement for individual jumps. i.e. notrack jmp rax Weakens the sandbox but at least the rest of the app gets function pointer integrity still.

@fd_ripatel static offsets don’t have this problem in the first place. how would you do this with callx when the call target is indirected and could be supplied completely dynamically? that makes *every* instruction a valid call target.

Linux 7.0 still does not support Intel CET indirect branch tracking (IBT) in usermode. Intel CPUs supporting IBT first appeared in 2021. Here's my patch series: @wii.dev/T/" target="_blank" rel="nofollow noopener">lore.kernel.org/lkml/202605171…

@deanmlittle The Agave JIT already tracks valid call targets and enforces them. They just need to emit endbr64 instructions.

@fd_ripatel i was researching this recently to see if we could use it to kill jit spraying attacks without all the expensive sanitization we currently do but it seems you'd need to either put it before each instruction boundary or somehow know all possible valid callx targets aot. 😢

@canadianbryan very cool, hopefully some motivation for Linux to accept my patches 🙂

OpenBSD has had IBT support since the latter part of 2023, for Tiger Lake+ (Intel 11th gen and newer). openbsd.org/74.html It's enabled by default in both the kernel and usermode (including ports, w/ less than ~100 marked USE_NOBTCFI, some aarch64 BTI only).

This came up while adding control flow integrity to Firedancer's sandbox. One of the best Linux x86 jails out there, enforcing process isolation, namespaces, strict seccomp, landlock, MPK (user protection keys), CFI, and soon more. github.com/firedancer-io/…

IBT enforces that indirect calls and jumps can't land on any arbitrary instruction, but one of these: [f3 0f 1e fa] endbr64 "jmp rax" to elsewhere causes a segfault SEGV_CPERR, defending against control flow hijacking (e.g. corrupt function pointer).

the day is finally here

@toly @SolanaSensei @solana @SolanaFndn @bw_solana 😴😴😴 Why do let the majority client pick protocol limits instead of giving validators a config option? Frankendancer has supported XDP for 2 years, so we're waiting on nothing. Just switch back to Agave once they sort out their performance issues

Big news from the SOLANA world — Sinon over at JUMP FIREDANCER just built the FASTEST Falcon implementation EVER, totally from scratch, using AVX512 (very advanced, very powerful stuff, most people have no idea). And get this — they’re giving it AWAY, upstreaming straight to the author's repo. That’s called CLASS, folks. Expect MANY more incredible open source contributions. Tremendous work. The best!​​​​​​​​​​​​​​​​ Thank you for your attention to this matter!

@JohnAlanWoods Solana (Sinon from @jump_firedancer) wrote *the* fastest Falcon implementation from scratch, using AVX512. The author is upstreaming their contributions: github.com/algorand/falco… Expect more good OSS contributions from them 🙂

tldr: copied Falcon.

@cavemanloverboy Bursting PoH at the start of the block was a bug but it improves performance, so I guess it can stay ... until PoH is finally gone

the funny part about tick distribution stuff is that the most IBRL thing to do is to ignore poh pacing entirely, get all of your tick shreds out as soon as possible to the network, and then just record your txns whenever they come through in the last few ticks (but throughout your slot in wall time) this is the default behavior in full fd. it hashes ASAP until the last two ticks, and then reserves the rest of the space for mixing in records until the pack tile says it's done. to do otherwise is to withhold tick shreds. recall that other nodes have to run poh verify during replay, so withholding them means they must do this 10-50ms of work later into the slot. ibrl.wtf/validator/DNVZ…
