  • Why do we need for an Undefined Behavior Annex to C++
    2 projects | news.ycombinator.com | 1 Mar 2024
    On Unix targets, it installs a signal handler for SIGSEGV and checks if the faulting address falls within the range of the stack guards. See https://github.com/rust-lang/rust/blob/411f34b/library/std/s...

    The stack guards would normally be setup by the system runtime (e.g. kernel in the case of the main thread stack, libc for thread stacks), not Rust's runtime. Likewise, stack probes that ensure stack operations don't skip guard pages are usually (always?) emitted by the compiler backend (e.g. GCC, LLVM), not Rust's instrumentation, per se.

    In this sense Rust isn't doing anything different than any other typical C or C++ binary, except hijacking SIGSEGV as Rust does is normally frowned upon, especially when it's merely for aesthetics--i.e. printing a pretty message. Also, attempting to introspect current thread metadata from a signal handler gives me pause. I'm not familiar enough with Rust to down the underlying code. I presume it's using at some POSIX threads interfaces, but POSIX thread interfaces aren't async-signal-safe, and though SIGSEGV is a synchronous signal, that doesn't mean the Rust runtime isn't technically relying on undefined behavior.

    You don't. It currently requires `-Z build-std=std,panic_abort` and some nightly flags (e.g. `#![feature(restricted_std)]`) but you can build `std` programs on bare metal targets. I can't remember exactly what it does if you try to open files or start threads or whatever (probably panics?) but you can compile and run it. If you don't do any of those things it works fine.

    Currently the `sys` crate implementation is hard-coded into the compiler but eventually you will be able to provide it without modifying the compiler so you can e.g. target a RTOS or whatever.

    It looks like that work started really recently actually:

    “Similarly, the reason why niko's approach is not yet implemented is simply that getting the type system to a point where we even can implement this is Hard. Fixing this bug is blocked on replacing the existing trait solver(s): #107374. A clean fix for this issue (and the ability to even consider using proof objects), will then also be blocked blocked on coinductive trait goals and explicit well formed bounds. We should then be able to add implications to the trait solver.

    So I guess the status is that we're slowly getting there but it is very hard, especially as we have to be incredibly careful to not break backwards compatibility.”

    Because Rust doesn't have a specification, we can argue back and forth forever about whether something is part of the "language design". The point is that we know how to solve the problem by desugaring [1] in a way that everyone basically expects to happen already. It's not going to break a significant amount of code: even the bigger sledgehammer of banning contravariance on function types was measured to not have much of an impact.

    As far as I can tell, the main reason to argue "language design" vs. "compiler bug" is to imply that language design issues threaten to bring down the entire foundation of the language. It doesn't work like that. Rust's type system isn't like a mathematical proof, where either the theorem is true or it's false and one mistake in the proof could invalidate the whole thing. It's a tool to help programmers avoid memory safety issues, and it's proven to be extremely good at that in practice. If there are problems with Rust's type system, they're identified and patched.

    I believe it really is a flaw in the language, it's impossible for any compiler to check contravariance properly in this edge case. I don't think anything in this link is incorrect: https://counterexamples.org/nearly-universal.html?highlight=... (and it seems the rustc types team endorses this analysis)

    I am not at all familiar with Miri. Does Miri consider a slightly different dialect of Rust where implicit constraints like this become explicit but inferred? Sort of like this proposal from the GH issue: https://github.com/rust-lang/rust/issues/25860#issuecomment-... but the "where" clause is inferred at compile time. If so I wouldn't call that a "fix" so much as a partial mitigation, useful for static analysis but not actually a solution to the problem in rustc. I believe that inference problem is undecidable in general and that rustc would need to do something else.

  • querySrv errors when connecting to MongoDB Atlas
    3 projects | dev.to | 29 Feb 2024
    Building with Go 1.11+ and using connection strings with the mongodb+srv scheme is unfortunately incompatible with some DNS servers in the wild due to the change introduced in https://github.com/golang/go/issues/10622. You may receive an error with the message "cannot unmarshal DNS message" while running an operation when using DNS servers that non-compliantly compress SRV records. Old versions of kube-dns and the native DNS resolver (systemd-resolver) on Ubuntu 18.04 are known to be non-compliant in this manner. We suggest using a different DNS server (8.8.8.8 is the common default), and, if that's not possible, avoiding the mongodb+srv scheme.

  • A beginner's guide to constant-time cryptography (2017)
    6 projects | news.ycombinator.com | 22 Feb 2024
    I noticed in July of 2022 that Go did exactly the vulnerable example and reported it to the security team.

    https://github.com/golang/go/issues/53849

    It was fixed as of Go 1.21 https://go.dev/doc/go1.21

    ---

    The article cites JavaScript, which is not constant time. There's no sure way to do constant time operations in JavaScript and thus no secure way to do crypto directly in Javascript. Browsers like Firefox depend on low level calls which should be implemented in languages that are constant time capable.

    JavaScript needs something like constant time WASM in order to do crypto securely, but seeing the only constant time WASM project on GitHub has only 16 stars and the last commit was 2 years ago, it doesn't appear to have much interest. https://github.com/WebAssembly/constant-time

    However, for JavaScript, I recommend Paul's library Noble which is "hardened to be algorithmically constant time". It is by far the best library available for JavaScript. https://github.com/paulmillr/noble-secp256k1

  • Maybe Everything Is a Coroutine
    3 projects | news.ycombinator.com | 14 Feb 2024
    > Channels are specifically designed to be a high-speed data bus between goroutines, rather than ever use more expensive and less safe shared memory.

    What do you mean? Shared memory is not more expensive. Memory is memory, it's either cached on your core or not. In fact, Go still has to issue fence instructions to ensure that the memory it observes after a channel read is sequenced after any writes to that memory, so it's at best the same cost you'd have with other forms of inter-thread communication in any language.

    Anyway, even that is missing the point. Go still shares memory if you used a reference type, and most types in Go end up being reference types, because it's the only way to have a variable-sized data structure (and while we're at it, string is the only variable-sized data structure that's also immutable).

    The bigger problem is that Go doesn't enforce thread safety. Channels only make communication safe if you send types that don't contain any mutable references... but Go doesn't give you any way to define your own immutable types. That basically limits you to just string. Instead people send slices, maps, pointers to structs, interfaces, etc. and those are all mutable and Go does nothing to enforce that you didn't mutate them.

    Even if all of that somehow wasn't true, many parallelism patterns simply don't map well to channels, so you still end up with mutexes in many parts of real world projects. Even if you don't see the mutexes, they're in your libraries. For example, Go's http.Transport contains a connection pool, but it uses mutexes instead of channels because even the Go team knows that mutexes still make sense for many real-world patterns.

    https://github.com/golang/go/blob/b6ca586181f3f1531c01d51d63...

    This whole "channels make Go safe" myth has to stop. It's confused a generation of Go programmers about the actual safety (and apparently performance) tradeoffs of channels. They do not make Go safer (mutable references are still mutable after being sent on a channel), they do not make it faster (the memory still has to be fenced), and heck while we're at it, they do not even make it simpler ("idiomatic" use of channels introduces many ways that goroutines can deadlock, and deadlock-free use of channels is much more complicated and less idiomatic).

    The most useful thing about channels is that you can select{} on multiple of them so they partly compensate for Go's limitations around selecting on futures in general. They're a poor substitute when you actually needed to select on something like IO, where io.Reader/Writer still don't interact with select, channels, or even cancellation directly.
