somehow the remapping of this syscall to the 64-bit version was overlooked. the issue was found, and patch provided, by Stefan Kristiansson. presumably the reason this bug was not caught earlier is that the syscall takes a pointer to off_t rather than a value, so on little-endian systems, everything appears to work as long as the offset value fits in the low 31 bits. on big-endian systems, though, sendfile was presumably completely non-functional.
musl libc
musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.
The 1.0 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.
For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
