2020-11-12Deflake tcp_socket test.Mithun Iyer
Increase the wait time for the thread to be blocked on read/write syscall. PiperOrigin-RevId: 342204627
2020-11-12Refactor SOL_SOCKET optionsNayana Bidari
Store all the socket level options in a struct and call {Get/Set}SockOpt on this struct. This will avoid implementing socket level options on all endpoints. This CL contains implementing one socket level option for tcp and udp endpoints. PiperOrigin-RevId: 342203981

2020-11-12Improve shim debug loggingFabricio Voznika
- Add log statements in service entry points. - Propagate `-debug` flag from shim invokation to the service - Load options when shim process is invoked to ensure runsc commands use the correct set of options, e.g. --debug --debug-logs=... - Add debug options to the shim configuration directly, so it doesn't rely on containerd configuration (and restart) to enable shim debug. - Save shim logs to dedicated file, so it's easier to read logs. They would be mixed with containerd logs and hard to distinguish otherwise. PiperOrigin-RevId: 342179868

2020-11-12Fix misuses of kernel.Task as context.Context.Jamie Liu
kernel.Task can only be used as context.Context by that Task's task goroutine. This is violated in at least two places: - In any case where one thread accesses the /proc/[tid] of any other thread, passing the kernel.Task for [tid] as the context.Context is incorrect. - Task.rebuildTraceContext() may be called by Kernel.RebuildTraceContexts() outside the scope of any task goroutine. Fix these (as well as a data race on Task.traceContext discovered during the course of finding the latter). PiperOrigin-RevId: 342174404
2020-11-12Add children names into verity hashChong Cai
children names map can be used to verify whether a child is expected during walking, so that we can detect unexpected modifications that deleted/renamed both the target file and the corresponding merkle tree file. PiperOrigin-RevId: 342170715
2020-11-12Pad with a loop rather than a copy from an allocation.Julian Elischer
Add a unit test for ipv4.Encode and a round trip test. PiperOrigin-RevId: 342169517
2020-11-12Remove TESTONLY tag from vfs2 flagFabricio Voznika
Updates #1035 PiperOrigin-RevId: 342168926
2020-11-12Rename kernel.TaskContext to kernel.TaskImage.Jamie Liu
This reduces confusion with context.Context (which is also relevant to kernel.Tasks) and is consistent with existing function kernel.LoadTaskImage(). PiperOrigin-RevId: 342167298
2020-11-12Move packet handling to NetworkEndpointGhanan Gowripalan
The NIC should not hold network-layer state or logic - network packet handling/forwarding should be performed at the network layer instead of the NIC. Fixes #4688 PiperOrigin-RevId: 342166985
2020-11-12Filter dentries with non-zero refs in VFS2 gofer/overlay checks.Jamie Liu
PiperOrigin-RevId: 342161204
2020-11-12[infra] Do not use debug flags for testing.Ayush Ranjan
This causes some networking related tests to take a very long time. Upon failure, tests can be manually run with debug flags to debug. As is the strace logs are not available from a test run. PiperOrigin-RevId: 342156294
2020-11-12Refactor merkletree testsChong Cai
Separate the test cases from TestVerify so that the test names reflect the test case better. PiperOrigin-RevId: 342152754

PiperOrigin-RevId: 341982672
2020-11-11Add documentation for reference counting.Dean Deng
Fixes #1486. PiperOrigin-RevId: 341966640
2020-11-11Teach netstack how to add options to IPv4 packetsJulian Elischer
Most packets don't have options but they are an integral part of the standard. Teaching the ipv4 code how to handle them will simplify future testing and use. Because Options are so rare it is worth making sure that the extra work is kept out of the fast path as much as possible. Prior to this change, all usages of the IHL field of the IPv4Fields/Encode system set it to the same constant value except in a couple of tests for bad values. From this change IHL will not be a constant as it will depend on the size of any Options. Since ipv4.Encode() now handles the options it becomes a possible source of errors to let the callers set this value, so remove it entirely and calculate the value from the size of the Options if present (or not) therefore guaranteeing a correct value. Fixes #4709 RELNOTES: n/a PiperOrigin-RevId: 341864765

2020-11-09Additions to ICMP and IPv4 parsersJulian Elischer
Teach ICMP.Parser/ToBytes to handle some non echo ICMP packets. Teach IPv4.Parser that fragments only have a payload, not an upper layer. Fix IPv4 and IPv6 reassembly tests to handle the change. Fixes #4758 PiperOrigin-RevId: 341549665

2020-11-09Skip `EventHUp` notify in `FIN_WAIT2` on a socket close.Mithun Iyer
This Notify was added as part of cl/279106406; but notifying `EventHUp` in `FIN_WAIT2` is incorrect, as we want to only notify later on `TIME_WAIT` or a reset. However, we do need to notify any blocked waiters of an activity on the endpoint with `EventIn`|`EventOut`. PiperOrigin-RevId: 341490913
2020-11-09net: connect to the ipv4 localhost returns ENETUNREACH if the address isn't setAndrei Vagin
cl/340002915 modified the code to return EADDRNOTAVAIL if connect is called for a localhost address which isn't set. But actually, Linux returns EADDRNOTAVAIL for ipv6 addresses and ENETUNREACH for ipv4 addresses. Updates #4735 PiperOrigin-RevId: 341479129

2020-11-09Initialize references with a value of 1.Dean Deng
This lets us avoid treating a value of 0 as one reference. All references using the refsvfs2 template must call InitRefs() before the reference is incremented/decremented, or else a panic will occur. Therefore, it should be pretty easy to identify missing InitRef calls during testing. Updates #1486. PiperOrigin-RevId: 341411151
2020-11-06Allow VFS2 gofer.dentries to have separate read and write FDs.Jamie Liu

2020-11-06[vfs] overlayfs: Do not unlink non-existing whiteout during file creation.Ayush Ranjan
We can reuse information about whether a whiteout exists on a given file path from stepLocked when creating a file at that path. This helps save an Unlink call to the upper filesystem if the whiteout does NOT exist (common case). Plumbs this information from lookupLocked() -> getChildLocked() -> stepLocked(). This also helped save a Lookup in RenameAt(). Fixes #1199 PiperOrigin-RevId: 341105351
2020-11-06Avoid extra DecRef on kernfs root for "kept" dentries.Dean Deng
The root dentry was not created through Inode.Lookup, so we should not release a reference even if inode.Keep() is true. PiperOrigin-RevId: 341103220
2020-11-06Fix infinite loop when splicing to pipes/eventfds.Nicolas Lacasse
Writes to pipes of size < PIPE_BUF are guaranteed to be atomic, so writes larger than that will return EAGAIN if the pipe has capacity < PIPE_BUF. Writes to eventfds will return EAGAIN if the write would cause the eventfd value to go over the max. In both such cases, calling Ready() on the FD will return true (because it is possible to write), but specific kinds of writes will in fact return EAGAIN. This CL fixes an infinite loop in splice and sendfile (VFS1 and VFS2) by forcing skipping the readiness check for the outfile in send, splice, and tee. PiperOrigin-RevId: 341102260
2020-11-06Do not send to the zero portGhanan Gowripalan
Port 0 is not meant to identify any remote port so attempting to send a packet to it should return an error. PiperOrigin-RevId: 341009528
