Note that most kinds of sockets are not yet supported in VFS2
(only Unix sockets are partially supported at the moment), so
these syscalls will still generally fail. Enabling them allows
us to begin running socket tests for VFS2 as more features are
ported over.
Updates #1476, #1478, #1484, #1485.

The comments in the ticket indicate that this behavior
is fine and that the ticket should be closed, so we shouldn't
need pointers to the ticket.

noNewPrivileges is ignored if set to false since gVisor assumes that
PR_SET_NO_NEW_PRIVS is always enabled.

As in VFS1, we only support the user.* namespace. Plumbing is added to tmpfs
and goferfs.
Note that because of the slightly different order of checks between VFS2 and
Linux, one of the xattr tests needs to be relaxed slightly.
Fixes #2363.

The sentry doesn't allow execve, but it's a good defense
in-depth measure.

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

Determine system time from within the sentry rather than relying on the remote
filesystem to prevent inconsistencies.
Resolve related TODOs; the time discrepancies in question don't exist anymore.

FileDescription references are side-effectual; for example, holding a reference
on the write end of a pipe prevents reads from the read end from returning EOF.
This change is consistent with Linux, but not VFS1; while VFS1 also has this
bug, it's less visible there since VFS1 procfs disables caching.

This fixes a bug in the proc net directory.

This required minor restructuring of how system call tables were saved
and restored, but it makes way more sense this way.
Updates #2243
|
|
Required directory checks were being skipped when there was
no child cached. Now the code always loads the child file
before unlinking it.

Check whether an fd is seekable by calling the seek syscall and
examining the return value, instead of checking the file type,
which is inaccurate.

We already have network namespace for netstack.

gofer operations accumulate dentries touched in a slice to call
checkCachingLocked on them when the operation is over. In case
the same dentry is touched multiple times during the operation,
checkCachingLocked, and consequently destroyLocked, may be called
more than once for the same dentry.
