2021-11-05Make {Un}Marshal{Bytes/Unsafe} return remaining buffer.Ayush Ranjan
Change marshal.Marshallable method signatures to return the remaining buffer. This makes it easier to implement these method manually. Without this, we would have to manually do buffer shifting which is error prone. tools/go_marshal/test:benchmark test does not show change in performance. Additionally fixed some marshalling bugs in fsimpl/fuse. Updated multiple callpoints to get rid of redundant slice indexing work and simplified code using this new signature.

2021-08-13[syserror] Remove pkg syserror.Zach Koopmans
Removes package syserror and moves still relevant code to either linuxerr or to syserr (to be later removed). Internal errors are converted from random types to *errors.Error types used in linuxerr. Internal errors are in linuxerr/internal.go. PiperOrigin-RevId: 390724202

This change will allow us to remove the default link in a packetimpact test so we can reduce indeterministic behaviors as required in https://fxbug.dev/78430. This will also help with testing #1388. Updates #578, #1388. PiperOrigin-RevId: 387896847

2021-06-22[syserror] Add conversions to linuxerr with temporary Equals method.Zach Koopmans

2021-06-16[syserror] Refactor linuxerr and error package.Zach Koopmans
Move Error struct to pkg/errors package for use in multiple places. Move linuxerr static definitions under pkg/errors/linuxerr. Add a lookup list for quick lookup of *errors.Error by errno. This is useful when converting syserror errors and unix.Errno/syscall.Errrno values to *errors.Error. Update benchmarks routines to include conversions. The below benchmarks show *errors.Error usage to be comparable to using unix.Errno.

On Linux these are meant to be equivalent to POLLIN/POLLOUT. Rather than hack these on in sys_poll etc it felt cleaner to just cleanup the call sites to notify for both events. This is what linux does as well. Fixes #5544 PiperOrigin-RevId: 364859977

2021-03-03[op] Replace syscall package usage with golang.org/x/sys/unix in pkg/.Ayush Ranjan
The syscall package has been deprecated in favor of golang.org/x/sys. Note that syscall is still used in the following places: - pkg/sentry/socket/hostinet/stack.go: some netlink related functionalities are not yet available in golang.org/x/sys. - syscall.Stat_t is still used in some places because os.FileInfo.Sys() still returns it and not unix.Stat_t.

2020-11-18[netstack] Move SO_PASSCRED option to SocketOptions.Ayush Ranjan
This change also makes the following fixes: - Make SocketOptions use atomic operations instead of having to acquire/drop locks upon each get/set option. - Make documentation more consistent. - Remove tcpip.SocketOptions from socketOpsCommon because it already exists in transport.Endpoint. - Refactors get/set socket options tests to be easily extendable.
