2020-02-25Port most syscalls to VFS2.Jamie Liu
pipe and pipe2 aren't ported, pending a slight rework of pipe FDs for VFS2. mount and umount2 aren't ported out of temporary laziness. access and faccessat need additional FSImpl methods to implement properly, but are stubbed to prevent googletest from CHECK-failing. Other syscalls require additional plumbing. Updates #1623 PiperOrigin-RevId: 297188448

2020-02-14Remove linux.EpollEvent.Fd.gVisor bot
glibc defines struct epoll_event in such a way that epoll_event.data.fd exists. However, the kernel's definition of struct epoll_event makes epoll_event.data an opaque uint64, so naming half of it "fd" just introduces confusion. Remove the Fd field, and make Data a [2]int32 to compensate. Also add required padding to linux.EpollEvent on ARM64. PiperOrigin-RevId: 295250424

2020-02-14Fix various issues related to enabling go-marshal.gVisor bot
- Add missing build tags to files in the abi package. - Add the marshal package as a sentry dependency, allowed by deps_test. - Fix an issue with our top-level go_library BUILD rule, which incorrectly shadows the variable containing the input set of source files. This caused the expansion for the go_marshal clause to silently omit input files. - Fix formatting when copying build tags to gomarshal-generated files. - Fix a bug with import statement collision detection in go-marshal.

2020-02-13We can now create and jump in iptables. For example:Kevin Krakauer
$ iptables -N foochain $ iptables -A INPUT -j foochain

2020-01-31iptables: enable TCP matching with "-m tcp".Kevin Krakauer
A couple other things that changed: - There's a proper extension registration system for matchers. Anyone adding another matcher can use tcp_matcher.go or udp_matcher.go as a template. - All logging and use of syserr.Error in the netfilter package happens at the highest possible level (public functions). Lower-level functions just return normal, descriptive golang errors.

2020-01-22Error marshalling the matcher.Kevin Krakauer
The iptables binary is looking for libxt_.so when it should be looking for libxt_udp.so, so it's having an issue reading the data in xt_match_entry. I think it may be an alignment issue. Trying to fix this is leading to me fighting with the metadata struct, so I'm gonna go kill that.
