2020-03-27Add vfs.PathnameReachable().Jamie Liu
/proc/[pid]/mount* omit mounts whose mount point is outside the chroot, which is checked (indirectly) via __d_path(). PiperOrigin-RevId: 303434226
2020-03-27Add FilesystemType.Name method, and FilesystemType field to Filesystem struct.Nicolas Lacasse
Both have analogues in Linux: * struct file_system_type has a char *name field. * struct super_block keeps a pointer to the file_system_type. These fields are necessary to support the `filesystem type` field in /proc/[pid]/mountinfo. PiperOrigin-RevId: 303434063
2020-03-27Support Hop By Hop and Destination Options ext hdrGhanan Gowripalan
Enables handling the Hop by Hop and Destination Options extension headers, but options are not yet supported. All options will be treated as unknown and their respective action will be followed. Note, the stack does not yet support sending ICMPv6 error messages in response to options that cannot be handled/parsed. That will come in a later change (Issue #2211). Tests: - header_test.TestIPv6UnknownExtHdrOption - header_test.TestIPv6OptionsExtHdrIterErr - header_test.TestIPv6OptionsExtHdrIter - ipv6_test.TestReceiveIPv6ExtHdrs PiperOrigin-RevId: 303433085

2020-03-26Add BoundEndpointAt filesystem operation.Dean Deng
BoundEndpointAt() is needed to support Unix sockets bound at a file path, corresponding to BoundEndpoint() in VFS1. Updates #1476. PiperOrigin-RevId: 303258251

2020-03-26Use host-defined file owner and mode, when possible, for imported fds.Dean Deng
Using the host-defined file owner matches VFS1. It is more correct to use the host-defined mode, since the cached value may become out of date. However, kernfs.Inode.Mode() does not return an error--other filesystems on kernfs are in-memory so retrieving mode should not fail. Therefore, if the host syscall fails, we rely on a cached value instead. Updates #1672. PiperOrigin-RevId: 303220864

2020-03-26Handle IPv6 Fragment & Routing extension headersGhanan Gowripalan
Enables the reassembly of fragmented IPv6 packets and handling of the Routing extension header with a Segments Left value of 0. Atomic fragments are handled as described in RFC 6946 to not interfere with "normal" fragment traffic. No specific routing header type is supported. Note, the stack does not yet support sending ICMPv6 error messages in response to IPv6 packets that cannot be handled/parsed. That will come in a later change (Issue #2211). Test: - header_test.TestIPv6RoutingExtHdr - header_test.TestIPv6FragmentExtHdr - header_test.TestIPv6ExtHdrIterErr - header_test.TestIPv6ExtHdrIter - ipv6_test.TestReceiveIPv6ExtHdrs - ipv6_test.TestReceiveIPv6Fragments RELNOTES: n/a PiperOrigin-RevId: 303189584

2020-03-26Add unique ID to Mount type.Nicolas Lacasse
Analagous to Linux's mount.mnt_id. This ID is displayed in /proc/[pid]/mountinfo. PiperOrigin-RevId: 303185564
2020-03-26Support owner matching for iptables.Nayana Bidari
This feature will match UID and GID of the packet creator, for locally generated packets. This match is only valid in the OUTPUT and POSTROUTING chains. Forwarded packets do not have any socket associated with them. Packets from kernel threads do have a socket, but usually no owner.

2020-03-25nogo: enable sanitizers.Adin Scannell
This enables all relevant santizers (though most analyzers will not find much, it will prevent instances from creeping in), and codifies existing exceptions in tools/nogo.js to be fixed.
2020-03-25Fix go_marshal Example name.Adin Scannell
There is a canonical naming convention for Examples, which are checked by analyzers. This must be fixed since adding exceptions for generated code will be more challenging.

2020-03-25Fix futex_benchmark.Jamie Liu
- Fix definitions of Futex* wrappers. - Correctly handle glibc syscall() (which returns -1 and sets errno instead of returning the raw syscall return value). - De-parameterize FutexWaitBitset, which was apparently intended to test with deadlines of between 0 and 100000 nanoseconds after the Unix epoch, but was broken due to the preceding two issues. - Use wall time to measure the durations of tests that are expected to block (and thus stop accumulating CPU time). - Require 5s for all tests to improve robustness in the presence of sentry GC. - Remove FutexContend and FutexContendDeadline; it's unclear what these are supposed to measure, given that (1) FutexLock is unrealistically inefficient and (2) the benchmark rewards slow scheduling (since this reduces contention).
