From 93d2003c9a4a35522b3528a4df638dd4e315bd14 Mon Sep 17 00:00:00 2001 From: Alex Crichton Date: Wed, 23 Jul 2025 07:27:01 -0700 Subject: [PATCH] Update `dlmalloc` dependency of libstd This primarily pulls in alexcrichton/dlmalloc-rs/55 and alexcrichton/dlmalloc-rs/54 to address 144199. Notably the highest byte in the wasm address space is no longer allocatable and additionally the allocator internally uses `wrapping_add` instead of `add` on pointers since on 32-bit platforms offsets might be larger than half the address space. --- library/Cargo.lock | 4 ++-- library/std/Cargo.toml | 2 +- 2 files changed, 3 insertions(+), 3 deletions(-) diff --git a/library/Cargo.lock b/library/Cargo.lock index 94155e0839817..cb356480ead8a 100644 --- a/library/Cargo.lock +++ b/library/Cargo.lock @@ -78,9 +78,9 @@ dependencies = [ [[package]] name = "dlmalloc" -version = "0.2.9" +version = "0.2.10" source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "d01597dde41c0b9da50d5f8c219023d63d8f27f39a27095070fd191fddc83891" +checksum = "fa3a2dbee57b69fbb5dbe852fa9c0925697fb0c7fbcb1593e90e5ffaedf13d51" dependencies = [ "cfg-if", "libc", diff --git a/library/std/Cargo.toml b/library/std/Cargo.toml index ba1e1f5218af7..57859ea914700 100644 --- a/library/std/Cargo.toml +++ b/library/std/Cargo.toml @@ -63,7 +63,7 @@ rand = { version = "0.9.0", default-features = false, features = ["alloc"] } rand_xorshift = "0.4.0" [target.'cfg(any(all(target_family = "wasm", target_os = "unknown"), target_os = "xous", all(target_vendor = "fortanix", target_env = "sgx")))'.dependencies] -dlmalloc = { version = "0.2.4", features = ['rustc-dep-of-std'] } +dlmalloc = { version = "0.2.10", features = ['rustc-dep-of-std'] } [target.x86_64-fortanix-unknown-sgx.dependencies] fortanix-sgx-abi = { version = "0.5.0", features = [
