chore(deps): bump libc from 0.2.189 to 0.2.190 by dependabot[bot] · Pull Request #1919 · hyperlight-dev/hyperlight

dependabot · 2026-10-12T07:30:58Z

Bumps libc from 0.2.189 to 0.2.190.

Release notes

0.2.190

There is now a single config for enabling 64-bit time_t: libc_unstable_time64. This can be set unconditionally; it opts in to 64-bit time_t on the following platforms that use 32-bit by default:

32-bit Linux-GNU

32-bit Linux-uClibc

32-bit Linux-musl. Note that setting this flag also enables some other changes that happend in musl v1.2.

32-bit Windows-GNU

ESP-IDF (all targets with this environment are 32-bit)

Most other 32-bit platforms are either already using 64-bit time_t, or are considered legacy and will not be gaining support from their upstream maintainers.

You can enable this using RUSTFLAGS:
RUSTFLAGS='--cfg=libc_unstable_time64' cargo ...
Note that there may still be some changes to features gated by this config option, hence "unstable" in its name. In the near future we will rename it to just libc_time64. Until then, please test it out and report any bugs you find!

Support

Add initial support for HelenOS (#4355)

Added

We are slowly filling out the Default implementations, to reduce the need for mem::zeroed() in user code:

Unix: Implement Default for a number of structs, especially on Apple platforms (#5576)

Linux, NetBSD: Give statvfs a Default impl (#5583)

Linux: Add Default to a linux/can.rs structs (#5257)

Other additions:

Expose the libc_unstable_time64 cfg (#5411)

Android, Glibc: Add pthread_gettid_np (#5359)

Android: Add RTLD_NEXT (#5323)

Android: Add reuseport BPF socket options (#5366)

Apple: Add TCP header flags, options and SACK limits (#5358)

Apple: Add NET_RT_DUMP2 (#5442)

Apple: Add posix_spawn_file_actions_add(f)chdir(_np) (#5558)

BSD: Add BPF_WORDALIGN (#5320)

BSD: Add lchmod and lchflags where supported (#5400)

BSD: Add minherit and related constants (#4849)

Docs: Add more links to public headers and manual pages (#5407), (#5485)

... (truncated)
