Bumps libc from 0.2.178 to 0.2.180.

Release notes

Sourced from libc's releases.

0.2.180

Added

  • QNX: Add missing BPF and ifreq structures (#4769)

Fixed

  • Linux, L4Re: address soundness issues of CMSG_NXTHDR (#4903)
  • Linux-like: Handle zero-sized payload differences in CMSG_NXTHDR (#4903)
  • Musl: Fix incorrect definitions of struct stat on some 32-bit architectures (#4914)
  • NetBSD: RISC-V 64: Correct mcontext type definitions (#4886)
  • uClibc: Re-enable __SIZEOF_PTHREAD_COND_T on non-L4Re uclibc (#4915)
  • uClibc: Restructure Linux netlink module to resolve build errors (#4915)

0.2.179

With this release, we now have unstable support for 64-bit time_t on 32-bit platforms with both Musl and Glibc. Testing is appreciated!

For now, these can be enabled by setting environment variables during build:

RUST_LIBC_UNSTABLE_MUSL_V1_2_3=1
RUST_LIBC_UNSTABLE_GNU_TIME_BITS=64

Note that the exact configuration will change in the future. Setting the MUSL_V1_2_3 variable also enables some newer API unrelated to time_t.

Added

  • L4Re: Add uclibc aarch64 support (#4479)
  • Linux, Android: Add a generic definition for XCASE (#4847)
  • Linux-like: Add NAME_MAX (#4888)
  • Linux: Add AT_EXECVE_CHECK (#4422)
  • Linux: Add the SUN_LEN macro (#4269)
  • Linux: add getitimer and setitimer (#4890)
  • Linux: add pthread_tryjoin_n and pthread_timedjoin_np (#4887)
  • Musl: Add unstable support for 64-bit time_t on 32-bit platforms (#4463)
  • NetBSD, OpenBSD: Add interface LINK_STATE_* definitions from sys/net/if.h (#4751)
  • QuRT: Add support for Qualcomm QuRT (#4845)
  • Types: Add Padding::uninit() (#4862)

Fixed

  • Glibc: Link old version of cf{g,s}et{i,o}speed (#4882)
  • L4Re: Fixes for pthread (#4479)
  • L4re: Fix a wide variety of incorrect definitions (#4479)
  • Musl: Fix the value of CPU_SETSIZE on musl 1.2+ (#4865)
  • Musl: RISC-V: fix public padding fields in stat/stat64 (#4463)
  • Musl: s390x: Fix definition of SIGSTKSZ/MINSIGSTKSZ (#4884)

... (truncated)

Looks like libc is up-to-date now, so this is no longer needed.
