2020-12-09[netstack] Make tcpip.Error savable.Ayush Ranjan
Earlier we could not save tcpip.Error objects in structs because upon restore the constant's address changes in netstack's error translation map and translating the error would panic because the map is based on the address of the tcpip.Error instead of the error itself. Now I made that translations map use the error message as key instead of the address. Added relevant synchronization mechanisms to protect the structure and initialize it upon restore.

2020-12-09Refactor the Makefile to avoid recursive Make.Adin Scannell
Recursive make is difficult to follow and debug. Drop this by using internal functions, which, while difficult, are easier than trying to following recursive invokations. Further simplify the Makefile by collapsing the image bits and removing the tools/vm directory, which is effectively unused. Fixes #4952 PiperOrigin-RevId: 346569133

2020-12-08Run tcpdump as rootTamir Duberstein
Prior to this change tcpdump would fail to create its output file because the destination directory was owned by root. This would later cause killall to fail, as tcpdump was not running.

2020-12-07Remove p9.fidRef.openedMuMichael Pratt
openedMu has lock ordering violations. Most locks go through OpenedFlag(), which is usually taken after renameMu and opMu. On the other hand, Tlopen takes openedMu before renameMu and opMu (via safelyRead). Resolving this violation is simple: just drop openedMu. The opened and openFlags fields are already protected by opMu in most cases, renameMu (for write) in one case (via safelyGlobal), and only in doWalk by neither. This is a bit ugly because opMu is supposed to be a "semantic" lock, but it works. I'm open to other suggestions. Note that doWalk has a race condition where a FID may open after the open check but before actually walking. This race existed before this change as well; it is not clear if it is problematic.

2020-12-05Fix zero receive window advertisements.Mithun Iyer
With the recent changes db36d948fa63ce950d94a5e8e9ebc37956543661, we try to balance the receive window advertisements between payload lengths vs segment overhead length. This works fine when segment size are much higher than the overhead, but not otherwise. In cases where the segment length is smaller than the segment overhead, we may end up not advertising zero receive window for long time and end up tail-dropping segments. This is especially pronounced when application socket reads are slow or stopped. In this change we do not grow the right edge of the receive window for smaller segment sizes similar to Linux. Also, we keep track of the socket buffer usage and let the window grow if the application is actively reading data. Fixes #4903 PiperOrigin-RevId: 345832012
