2020-09-24Fix socket record leak in VFS2Tiwei Bie
VFS2 socket record is not removed from the system-wide socket table when the socket is released, which will lead to a memory leak. This patch fixes this issue. Fixes: #3874 Signed-off-by: Tiwei Bie <tiwei.btw@antgroup.com>

2020-07-15hostinet: fix fd leak in fdnotifier for VFS2Tiwei Bie
When we failed to create the new socket after adding the fd to fdnotifier, we should remove the fd from fdnotifier, because we are going to close the fd directly. Fixes: #3241 Signed-off-by: Tiwei Bie <tiwei.btw@antgroup.com>
2020-07-06hostinet: fix not specifying family fieldJianfeng Tan
Creating sockets by hostinet with VFS2 fails due to triggerring a seccomp violation. In essence, we fails to pass down the field of family. We fix this by passing down this field, family. Fixes #3141 Signed-off-by: Jianfeng Tan <henry.tjf@antfin.com>

2020-06-17Implement POSIX locksFabricio Voznika
- Change FileDescriptionImpl Lock/UnlockPOSIX signature to take {start,length,whence}, so the correct offset can be calculated in the implementations. - Create PosixLocker interface to make it possible to share the same locking code from different implementations.

2020-05-19Fix flaky udp tests by polling before reading.Dean Deng
On native Linux, calling recv/read right after send/write sometimes returns EWOULDBLOCK, if the data has not made it to the receiving socket (even though the endpoints are on the same host). Poll before reading to avoid this. Making this change also uncovered a hostinet bug (gvisor.dev/issue/2726), which is noted in this CL. PiperOrigin-RevId: 312320587

2020-05-01Port netstack, hostinet, and netlink sockets to VFS2.Dean Deng
All three follow the same pattern: 1. Refactor VFS1 sockets into socketOpsCommon, so that most of the methods can be shared with VFS2. 2. Create a FileDescriptionImpl with the corresponding socket operations, rewriting the few that cannot be shared with VFS1. 3. Set up a VFS2 socket provider that creates a socket by setting up a dentry in the global Kernel.socketMount and connecting it with a new FileDescription. This mostly completes the work for porting sockets to VFS2, and many syscall tests can be enabled as a result. There are several networking-related syscall tests that are still not passing: 1. net gofer tests 2. socketpair gofer tests 2. sendfile tests (splice is not implemented in VFS2 yet) Updates #1478, #1484, #1485 PiperOrigin-RevId: 309457331
