2019-09-30Fix bugs in PickEphemeralPort for TCP.Bhasker Hariharan
Netstack always picks a random start point everytime PickEphemeralPort is called. While this is required for UDP so that DNS requests go out through a randomized set of ports it is not required for TCP. Infact Linux explicitly hashes the (srcip, dstip, dstport) and a one time secret initialized at start of the application to get a random offset. But to ensure it doesn't start from the same point on every scan it uses a static hint that is incremented by 2 in every call to pick ephemeral ports. The reason for 2 is Linux seems to split the port ranges where active connects seem to use even ones while odd ones are used by listening sockets. This CL implements a similar strategy where we use a hash + hint to generate the offset to start the search for a free Ephemeral port. This ensures that we cycle through the available port space in order for repeated connects to the same destination and significantly reduces the chance of picking a recently released port.

2019-09-30Force timestamps to update when set via InodeOperations.SetTimestamps.Nicolas Lacasse
The gofer's CachingInodeOperations implementation contains an optimization for the common open-read-close pattern when we have a host FD. In this case, the host kernel will update the timestamp for us to a reasonably close time, so we don't need an extra RPC to the gofer. However, when the app explicitly sets the timestamps (via futimes or similar) then we actually DO need to update the timestamps, because the host kernel won't do it for us. To fix this, a new boolean `forceSetTimestamps` was added to CachineInodeOperations.SetMaskedAttributes. It is only set by gofer.InodeOperations.SetTimestamps. PiperOrigin-RevId: 272048146

2019-09-29Ensure runsc is uploaded.Adin Scannell
One would reasonably assume that a field named "regex" would expect a regular expression. However, in this case, one would be wrong. The "regex" field actually requires "FileSet" [1] syntax. ?\_(?)_/? [1] http://ant.apache.org/manual/Types/fileset.html PiperOrigin-RevId: 271917356

Before https://golang.org/cl/173160 syscall.RawSyscall would zero out the last three register arguments to the system call. That no longer happens. For system calls that take more than three arguments, use RawSyscall6 to ensure that we pass zero, not random data, for the additional arguments. PiperOrigin-RevId: 271062527

2019-09-24Return only primary addresses in Stack.NICInfo()Chris Kuiper
Non-primary addresses are used for endpoints created to accept multicast and broadcast packets, as well as "helper" endpoints (0.0.0.0) that allow sending packets when no proper address has been assigned yet (e.g., for DHCP). These addresses are not real addresses from a user point of view and should not be part of the NICInfo() value. Also see b/127321246 for more info. This switches NICInfo() to call a new NIC.PrimaryAddresses() function. To still allow an option to get all addresses (mostly for testing) I added Stack.GetAllAddresses() and NIC.AllAddresses(). In addition, the return value for GetMainNICAddress() was changed for the case where the NIC has no primary address. Instead of returning an error here, it now returns an empty AddressWithPrefix() value. The rational for this change is that it is a valid case for a NIC to have no primary addresses. Lastly, I refactored the code based on the new additions. PiperOrigin-RevId: 270971764

2019-09-24tty: fix sending SIGTTOU on tty writehenry.tjf
How to reproduce: $ echo "timeout 10 ls" > foo.sh $ chmod +x foo.sh $ ./foo.sh (will hang here for 10 secs, and the output of ls does not show) When "ls" process writes to stdout, it receives SIGTTOU signal, and hangs there. Until "timeout" process timeouts, and kills "ls" process. The expected result is: "ls" writes its output into tty, and terminates immdedately, then "timeout" process receives SIGCHLD and terminates. The reason for this failure is that we missed the check for TOSTOP (if set, background processes will receive the SIGTTOU signal when they do write). We use drivers/tty/n_tty.c:n_tty_write() as a reference.
