This is the case for all consumers of the std::sys::pal::weak::weak macro, as it is defining weak functions which don't show up in LLVM IR metadata. CFI fails for all these functions. Similar to other such cases in https://github.com/rust-lang/rust/issues/115199, this change stops emitting the CFI typecheck for consumers of the macro via the \#[no_sanitize(cfi)] attribute. --- library/std/src/sys/fs/unix.rs | 12 ++++++++++++ library/std/src/sys/pal/unix/fd.rs | 1 + library/std/src/sys/pal/unix/process/process_unix.rs | 1 + library/std/src/sys/pal/unix/thread.rs | 1 + library/std/src/sys/pal/unix/time.rs | 9 +++++++++ library/std/src/sys/pal/unix/weak.rs | 3 +++ 6 files changed, 27 insertions(+) diff --git a/library/std/src/sys/fs/unix.rs b/library/std/src/sys/fs/unix.rs index 914971934bfb0..d95735978c199 100644 --- a/library/std/src/sys/fs/unix.rs +++ b/library/std/src/sys/fs/unix.rs @@ -1454,6 +1454,18 @@ impl File { Ok(()) } + #[cfg_attr( + any( + target_os = "android", + all( + target_os = "linux", + target_env = "gnu", + target_pointer_width = "32", + not(target_arch = "riscv32") + ) + ), + no_sanitize(cfi) + )] pub fn set_times(&self, times: FileTimes) -> io::Result<()> { #[cfg(not(any( target_os = "redox", diff --git a/library/std/src/sys/pal/unix/fd.rs b/library/std/src/sys/pal/unix/fd.rs index 2fc33bdfefbf5..6da329288f746 100644 --- a/library/std/src/sys/pal/unix/fd.rs +++ b/library/std/src/sys/pal/unix/fd.rs @@ -251,6 +251,7 @@ impl FileDesc { } #[cfg(all(target_os = "android", target_pointer_width = "32"))] + #[no_sanitize(cfi)] pub fn read_vectored_at(&self, bufs: &mut [IoSliceMut<'_>], offset: u64) -> io::Result { super::weak::weak!(fn preadv64(libc::c_int, *const libc::iovec, libc::c_int, off64_t) -> isize);
