2020-09-09Fix BadSocketPair for open source.Zach Koopmans
BadSocketPair test will return several errnos (EPREM, ESOCKTNOSUPPORT, EAFNOSUPPORT) meaning the test is just too specific. Checking the syscall fails is appropriate. PiperOrigin-RevId: 328813071
2020-09-09Skip IPv6UDPUnboundSocketNetlinkTest on native linuxGhanan Gowripalan
...while we figure out of we want to consider the loopback interface bound to all IPs in an assigned IPv6 subnet, or not (to maintain compatibility with Linux). PiperOrigin-RevId: 328807974

2020-09-09Fix JobControl tests for open source.Zach Koopmans
ioctl calls with TIOCSCTTY fail if the calling process already has a controlling terminal, which occurs on a 5.4 kernel like our Ubuntu 18 CI. Thus, run tests calling ioctl TTOCSCTTY in clean subprocess. Also, while we're here, switch out non-inclusive master/slave for main/replica. PiperOrigin-RevId: 328756598

2020-09-09Expose basic coverage information to userspace through kcov interface.Dean Deng
In Linux, a kernel configuration is set that compiles the kernel with a custom function that is called at the beginning of every basic block, which updates the memory-mapped coverage information. The Go coverage tool does not allow us to inject arbitrary instructions into basic blocks, but it does provide data that we can convert to a kcov-like format and transfer them to userspace through a memory mapping. Note that this is not a strict implementation of kcov, which is especially tricky to do because we do not have the same coverage tools available in Go that that are available for the actual Linux kernel. In Linux, a kernel configuration is set that compiles the kernel with a custom function that is called at the beginning of every basic block to write program counters to the kcov memory mapping. In Go, however, coverage tools only give us a count of basic blocks as they are executed. Every time we return to userspace, we collect the coverage information and write out PCs for each block that was executed, providing userspace with the illusion that the kcov data is always up to date. For convenience, we also generate a unique synthetic PC for each block instead of using actual PCs. Finally, we do not provide thread-specific coverage data (each kcov instance only contains PCs executed by the thread owning it); instead, we will supply data for any file specified by -- instrumentation_filter. Also, fix issue in nogo that was causing pkg/coverage:coverage_nogo compilation to fail. PiperOrigin-RevId: 328426526
2020-09-09remove iptables sockopt special casesKevin Krakauer
iptables sockopts were kludged into an unnecessary check, this properly relegates them to the {get,set}SockOptIP functions. PiperOrigin-RevId: 328395135
2020-09-09Support SO_LINGER socket option.Nayana Bidari
When SO_LINGER option is enabled, the close will not return until all the queued messages are sent and acknowledged for the socket or linger timeout is reached. If the option is not set, close will return immediately. This option is mainly supported for connection oriented protocols such as TCP. PiperOrigin-RevId: 328350576
2020-09-09Fix TCP_LINGER2 behavior to match linux.Bhasker Hariharan
We still deviate a bit from linux in how long we will actually wait in FIN-WAIT-2. Linux seems to cap it with TIME_WAIT_LEN and it's not completely obvious as to why it's done that way. For now I think we can ignore that and fix it if it really is an issue. PiperOrigin-RevId: 328324922
2020-09-09Consider loopback bound to all addresses in subnetGhanan Gowripalan
When a loopback interface is configurd with an address and associated subnet, the loopback should treat all addresses in that subnet as an address it owns. This is mimicking linux behaviour as seen below: ``` $ ip addr show dev lo 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group ... link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever $ ping 192.0.2.1 PING 192.0.2.1 (192.0.2.1) 56(84) bytes of data. ^C --- 192.0.2.1 ping statistics --- 2 packets transmitted, 0 received, 100% packet loss, time 1018ms $ ping 192.0.2.2 PING 192.0.2.2 (192.0.2.2) 56(84) bytes of data. ^C --- 192.0.2.2 ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 2039ms $ sudo ip addr add 192.0.2.1/24 dev lo $ ip addr show dev lo 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group ... link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet 192.0.2.1/24 scope global lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever $ ping 192.0.2.1 PING 192.0.2.1 (192.0.2.1) 56(84) bytes of data. 64 bytes from 192.0.2.1: icmp_seq=1 ttl=64 time=0.131 ms 64 bytes from 192.0.2.1: icmp_seq=2 ttl=64 time=0.046 ms 64 bytes from 192.0.2.1: icmp_seq=3 ttl=64 time=0.048 ms ^C --- 192.0.2.1 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2042ms rtt min/avg/max/mdev = 0.046/0.075/0.131/0.039 ms $ ping 192.0.2.2 PING 192.0.2.2 (192.0.2.2) 56(84) bytes of data. 64 bytes from 192.0.2.2: icmp_seq=1 ttl=64 time=0.131 ms 64 bytes from 192.0.2.2: icmp_seq=2 ttl=64 time=0.069 ms 64 bytes from 192.0.2.2: icmp_seq=3 ttl=64 time=0.049 ms 64 bytes from 192.0.2.2: icmp_seq=4 ttl=64 time=0.035 ms ^C --- 192.0.2.2 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3049ms rtt min/avg/max/mdev = 0.035/0.071/0.131/0.036 ms ``` Test: integration_test.TestLoopbackAcceptAllInSubnet PiperOrigin-RevId: 328188546

2020-08-19Skip ECN test for native/linux tests.Zach Koopmans
Skip check for ECN bits in native/linux tests. General advice for the ECN field is to leave the setting to the kernel, so behavior of the test is undefined for different kernels. http://www.masterraghu.com/subjects/np/introduction/unix_network_programming_v1.3/ch07lev1sec6.html PiperOrigin-RevId: 327451414

2020-08-19[vfs] Do O_DIRECTORY check after resolving symlinks.Ayush Ranjan
Fixes python runtime test test_glob. Updates #3515 We were checking is the to-be-opened dentry is a dir or not before resolving symlinks. We should check that after resolving symlinks. This was preventing us from opening a symlink which pointed to a directory with O_DIRECTORY. Also added this check in tmpfs and removed a duplicate check. PiperOrigin-RevId: 327085895

2020-08-13[vfs2][gofer] Fix file creation flags sent to gofer.Ayush Ranjan
Fixes php runtime test ext/standard/tests/file/readfile_basic.phpt Fixes #3516 fsgofers only want the access mode in the OpenFlags passed to Create(). If more flags are supplied (like O_APPEND in this case), read/write from that fd will fail with EBADF. See runsc/fsgofer/fsgofer.go:WriteAt() VFS2 was providing more than just access modes. So filtering the flags using p9.OpenFlagsModeMask == linux.O_ACCMODE fixes the issue. Gofer in VFS1 also only extracts the access mode flags while making the create RPC. See pkg/sentry/fs/gofer/path.go:Create() Even in VFS2, when we open a handle, we extract out only the access mode flags + O_TRUNC. See third_party/gvisor/pkg/sentry/fsimpl/gofer/handle.go:openHandle() Added a test for this. PiperOrigin-RevId: 326574829

2020-08-13Ensure TCP TIME-WAIT is not terminated prematurely.Bhasker Hariharan
Netstack's TIME-WAIT state for a TCP socket could be terminated prematurely if the socket entered TIME-WAIT using shutdown(..., SHUT_RDWR) and then was closed using close(). This fixes that bug and updates the tests to verify that Netstack correctly honors TIME-WAIT under such conditions. Fixes #3106 PiperOrigin-RevId: 326456443
2020-08-12[vfs2][gofer] Return appropriate errors when opening and creating files.Ayush Ranjan
Fixes php test ext/standard/tests/file/touch_variation5.phpt on vfs2. Updates #3516 Also spotted a bug with O_EXCL, where we did not return EEXIST when we tried to open the root of the filesystem with O_EXCL | O_CREAT. Added some more tests for open() corner cases. PiperOrigin-RevId: 326346863

Before kernel version 4.16-rc6, fuse mount is protected by capable(CAP_SYS_ADMIN). After this version, it uses ns_capable(CAP_SYS_ADMIN) to protect. Before the 4.16 kernel, it was not allowed to mount fuse file systems without the global CAP_SYS_ADMIN. Fixes #3360
