2020-08-10Run GC before sandbox exit when leak checking is enabled.Dean Deng
Running garbage collection enqueues all finalizers, which are used by the refs/refs_vfs2 packages to detect reference leaks. Note that even with GC, there is no guarantee that all finalizers will be run before the program exits. This is a best effort attempt to activate leak checks as much as possible. Updates #3545.

2020-08-07[vfs2] Fix tmpfs mounting.Ayush Ranjan
Earlier we were using NLink to decide if /tmp is empty or not. However, NLink at best tells us about the number of subdirectories (via the ".." entries). NLink = n + 2 for n subdirectories. But it does not tell us if the directory is empty. There still might be non-directory files. We could also not rely on NLink because host overlayfs always returned 1. VFS1 uses Readdir to decide if the directory is empty. Used a similar approach. We now use IterDirents to decide if the "/tmp" directory is empty. Fixes #3369 PiperOrigin-RevId: 325554234

2020-08-07Fix panic during Address Resolution of neighbor entry created by NSSam Balana
When a Neighbor Solicitation is received, a neighbor entry is created with the remote host's link layer address, but without a link layer address resolver. If the host decides to send a packet addressed to the IP address of that neighbor entry, Address Resolution starts with a nil pointer to the link layer address resolver. This causes the netstack to panic and crash. This change ensures that when a packet is sent in that situation, the link layer address resolver will be set before Address Resolution begins.
