2021-03-29[syserror] Split usermem packageZach Koopmans
Split usermem package to help remove syserror dependency in go_marshal. New hostarch package contains code not dependent on syserror. PiperOrigin-RevId: 365651233

2021-03-15Make netstack (//pkg/tcpip) buildable for 32 bitKevin Krakauer
Doing so involved breaking dependencies between //pkg/tcpip and the rest of gVisor, which are discouraged anyways. Tested on the Go branch via: gvisor.dev/gvisor/pkg/tcpip/... Addresses #1446. PiperOrigin-RevId: 363081778

2020-11-16Remove ARP address workaroundGhanan Gowripalan
- Make AddressableEndpoint optional for NetworkEndpoint. Not all NetworkEndpoints need to support addressing (e.g. ARP), so AddressableEndpoint should only be implemented for protocols that support addressing such as IPv4 and IPv6. With this change, tcpip.ErrNotSupported will be returned by the stack when attempting to modify addresses on a network endpoint that does not support addressing. Now that packets are fully handled at the network layer, and (with this change) addresses are optional for network endpoints, we no longer need the workaround for ARP where a fake ARP address was added to each NIC that performs ARP so that packets would be delivered to the ARP layer.

2020-10-08Do not resolve routes immediatelyGhanan Gowripalan
When a response needs to be sent to an incoming packet, the stack should consult its neighbour table to determine the remote address's link address. When an entry does not exist in the stack's neighbor table, the stack should queue the packet while link resolution completes. See comments. PiperOrigin-RevId: 336185457

2020-01-27Update package locations.Adin Scannell
Because the abi will depend on the core types for marshalling (usermem, context, safemem, safecopy), these need to be flattened from the sentry directory. These packages contain no sentry-specific details. PiperOrigin-RevId: 291811289

2019-06-18gvisor/fs: don't update file.offset for sockets, pipes, etcAndrei Vagin
sockets, pipes and other non-seekable file descriptors don't use file.offset, so we don't need to update it. With this change, we will be able to call file operations without locking the file.mu mutex. This is already used for pipes in the splice system call. PiperOrigin-RevId: 253746644

2019-05-21Add basic plumbing for splice and stub implementation.Adin Scannell
This does not actually implement an efficient splice or sendfile. Rather, it adds a generic plumbing to the file internals so that this can be added. All file implementations use the stub fileutil.NoSplice implementation, which causes sendfile and splice to fall back to an internal copy. A basic splice system call interface is added, along with a test. PiperOrigin-RevId: 249335960 Change-Id: Ic5568be2af0a505c19e7aec66d5af2480ab0939b

2019-04-02device: fix device major/minorWei Zhang
Current gvisor doesn't give devices a right major and minor number. When testing golang supporting of gvisor, I run the test case below: ``` $ docker run -ti --runtime runsc golang:1.12.1 bash -c "cd /usr/local/go/src && ./run.bash " ``` And it reports some errors, one of them is: "--- FAIL: TestDevices (0.00s) --- FAIL: TestDevices//dev/null_1:3 (0.00s) dev_linux_test.go:45: for /dev/null Major(0x0) == 0, want 1 dev_linux_test.go:48: for /dev/null Minor(0x0) == 0, want 3 dev_linux_test.go:51: for /dev/null Mkdev(1, 3) == 0x103, want 0x0 --- FAIL: TestDevices//dev/zero_1:5 (0.00s) dev_linux_test.go:45: for /dev/zero Major(0x0) == 0, want 1 dev_linux_test.go:48: for /dev/zero Minor(0x0) == 0, want 5 dev_linux_test.go:51: for /dev/zero Mkdev(1, 5) == 0x105, want 0x0 --- FAIL: TestDevices//dev/random_1:8 (0.00s) dev_linux_test.go:45: for /dev/random Major(0x0) == 0, want 1 dev_linux_test.go:48: for /dev/random Minor(0x0) == 0, want 8 dev_linux_test.go:51: for /dev/random Mkdev(1, 8) == 0x108, want 0x0 --- FAIL: TestDevices//dev/full_1:7 (0.00s) dev_linux_test.go:45: for /dev/full Major(0x0) == 0, want 1 dev_linux_test.go:48: for /dev/full Minor(0x0) == 0, want 7 dev_linux_test.go:51: for /dev/full Mkdev(1, 7) == 0x107, want 0x0 --- FAIL: TestDevices//dev/urandom_1:9 (0.00s) dev_linux_test.go:45: for /dev/urandom Major(0x0) == 0, want 1 dev_linux_test.go:48: for /dev/urandom Minor(0x0) == 0, want 9 dev_linux_test.go:51: for /dev/urandom Mkdev(1, 9) == 0x109, want 0x0 " So I think we'd better assign to them correct major/minor numbers following linux spec.
