2021-08-30[syserr] Fix SIGBUS on syserr.FromErrorZach Koopmans
Fix syzcaller panic SIGBUS on error handling. Done by adding an interface, errors.GuestError, which errors can implement in order to be compared against each other. PiperOrigin-RevId: 393867554
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
2021-07-01[syserror] Update several syserror errors to linuxerr equivalents.Zach Koopmans
Update/remove most syserror errors to linuxerr equivalents. For list of removed errors, see //pkg/syserror/syserror.go. PiperOrigin-RevId: 382574582
2021-06-29[syserror] Change syserror to linuxerr for E2BIG, EADDRINUSE, and EINVALZach Koopmans
Remove three syserror entries duplicated in linuxerr. Because of the linuxerr.Equals method, this is a mere change of return values from syserror to linuxerr definitions. Done with only these three errnos as CLs removing all grow to a significantly large size. PiperOrigin-RevId: 382173835
2021-06-22[syserror] Add conversions to linuxerr with temporary Equals method.Zach Koopmans
Add Equals method to compare syserror and unix.Errno errors to linuxerr errors. This will facilitate removal of syserror definitions in a followup, and finding needed conversions from unix.Errno to linuxerr. PiperOrigin-RevId: 380909667
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.

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.
