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.

2020-01-09New sync package.Ian Gudger
* Rename syncutil to sync. * Add aliases to sync types. * Replace existing usage of standard library sync package. This will make it easier to swap out synchronization primitives. For example, this will allow us to use primitives from github.com/sasha-s/go-deadlock to check for lock ordering violations. Updates #1472 PiperOrigin-RevId: 289033387

This change also adds extensive testing to the p9 package via mocks. The sanity checks and type checks are moved from the gofer into the core package, where they can be more easily validated. PiperOrigin-RevId: 218296768 Change-Id: I4fc3c326e7bf1e0e140a454cbacbcc6fd617ab55

2018-08-08Fix error handling for bad message sizes.Adin Scannell
The message size check is legitimate: the size must be negotiated, which relies on the fixed message limit up front. Sending a message larger than that indicates that the connection is out of sync and is considered a socket error (disconnect). Similarly, sending a size that is too small indicates that the stream is out-of-sync or invalid. PiperOrigin-RevId: 207996551 Change-Id: Icd8b513d5307e9d5953dbb957ee70ceea111098d
