2020-12-02[netstack] Refactor common utils out of netstack to socket package.Ayush Ranjan
Moved AddressAndFamily() and ConvertAddress() to socket package from netstack. This helps because these utilities are used by sibling netstack packages. Such sibling dependencies can later cause circular dependencies. Common utils shared between siblings should be moved up to the parent. PiperOrigin-RevId: 345275571

2020-09-29Replace remaining uses of reflection-based marshalling.Rahat Mahmood
- Rewrite arch.Stack.{Push,Pop}. For the most part, stack now implements marshal.CopyContext and can be used as the target of marshal operations. Stack.Push had some extra logic for automatically null-terminating slices. This was only used for two specific types of slices, and is now handled explicitly. - Delete usermem.CopyObject{In,Out}. - Replace most remaining uses of the encoding/binary package with go-marshal. Most of these were using the binary package to compute the size of a struct, which go-marshal can directly replace. ~3 uses of the binary package remain. These aren't reasonably replaceable by go-marshal: for example one use is to construct the syscall trampoline for systrap. - Fill out remaining convenience wrappers in the primitive package.

2020-04-10Remove TODO from kernel.StracerFabricio Voznika
The dependency strace=>kernel grew over time. strace also depends on task's FD table and FSContext. It could be fixed with some interfaces the other way, but then we're trading an interface for another, and kernel.Stracer is likely cleaner. Closes #155 PiperOrigin-RevId: 305909678

2019-12-10Add all upstream syscalls to tablesMichael Pratt
Package strace is missing some syscalls we actually implement (e.g., getrandom). We also see newer syscalls sometimes (e.g., membarrier) that would be handy to have formatted. Let's go ahead and add all syscalls in the latest upstream release (v5.4), even though we only intend to implement v4.4. None of them are implemented, just included as placeholders.
