Release Notes

rust-lang/libc (libc)

v0.2.184

Compare Source

MSRV

This release increases the MSRV of libc to 1.65. With this update, you can now always use the
core::ffi::c_* types with libc definitions, since libc has been changed to reexport from
core rather than redefining them. (This usually worked before but had edge cases.)
(#​4972)

Added
  • BSD: Add IP_MINTTL to bsd (#​5026)
  • Cygwin: Add TIOCM_DSR (#​5031)
  • FreeBSD: Added xfile structe and file descriptor types (#​5002)
  • Linux: Add CAN netlink bindings (#​5011)
  • Linux: Add struct ethhdr (#​4239)
  • Linux: Add struct ifinfomsg (#​5012)
  • Linux: Define max_align_t for riscv64 (#​5029)
  • NetBSD: Add missing CLOCK_ constants (#​5020)
  • NuttX: Add _SC_HOST_NAME_MAX (#​5004)
  • VxWorks: Add flock and F_*LCK constants (#​4043)
  • WASI: Add all _SC_* sysconf constants (#​5023)
Deprecated

The remaining fixed-width integer aliases, __uint128_t, __uint128, __int128_t, and __int128,
have been deprecated. Use i128 and u128 instead. (#​4343)

Fixed
  • breaking Redox: Fix signal action constant types (#​5009)
  • EspIDF: Correct the value of DT_* constants (#​5034)
  • Redox: Fix locale values and add RTLD_NOLOAD, some TCP constants (#​5025)
  • Various: Use Padding::new(<zeroed>) rather than Padding::uninit() (#​5036)
Changed
  • potentially breaking Linux: Add new fields to struct ptrace_syscall_info (#​4966)
  • Re-export core::ffi integer types rather than redefining (#​5015)
  • Redox: Update F_DUPFD, IP, and TCP constants to match relibc (#​4990)
