>As of this article, lxss.sys has ~235 of the Linux syscalls implemented with varying level of support.

Is there a list of these syscalls somewhere? It would be cool to check it against the recent Linux API compatibility paper [0, 1].

You piqued my curiosity - just made one by extracting the syscall dispatch table from lxcore.sys and placing it alongside the Linux syscall list: https://goo.gl/QHGe1U

A lot of coverage there, but interesting to see which ones aren't yet implemented, at least in the recent build 14342.

(I used Filippo Valsorda's work from https://filippo.io/linux-syscall-table as the Linux syscall data source.)

A list of (at least partly) supported syscalls is here: https://msdn.microsoft.com/en-us/commandline/wsl/release_not...

Not details on which one are fully or partly supported, though.
