2019-12-19futex: wake one waiter if futex_wake is called with a non-positive valueAndrei Vagin
This change is needed to be compatible with the Linux kernel. There is no glibc wrapper for the futex system call, so it is easy to make a mistake and call syscall(__NR_futex, FUTEX_WAKE, addr) without the fourth argument. This works on Linux, because it wakes one waiter even if val is nonpositive. PiperOrigin-RevId: 286494396

2019-12-19Make masterInodeOperations.Truncate take a pointer receiver.Nicolas Lacasse
Otherwise a copy happens, which triggers a data race when reading masterInodeOperations.SimpleFileOperations.uattr, which must be accessed with a lock held. PiperOrigin-RevId: 286464473

2019-12-18net/tcp: allow to call listen without bindAndrei Vagin
When listen(2) is called on an unbound socket, the socket is automatically bound to a random free port with the local address set to INADDR_ANY. PiperOrigin-RevId: 286305906

2019-12-18Allow 'out-of-line' routing table updates for Router and Prefix discovery eventsGhanan Gowripalan
This change removes the requirement that a new routing table be provided when a router or prefix discovery event happens so that an updated routing table may be provided to the stack at a later time from the event. This change is to address the use case where the netstack integrator may need to obtain a lock before providing updated routes in response to the events above. As an example, say we have an integrator that performs the below two operations operations as described: A. Normal route update: 1. Obtain integrator lock 2. Update routes in the integrator 3. Call Stack.SetRouteTable with the updated routes 3.1. Obtain Stack lock 3.2. Update routes in Stack 3.3. Release Stack lock 4. Release integrator lock B. NDP event triggered route update: 1. Obtain Stack lock 2. Call event handler 2.1. Obtain integrator lock 2.2. Update routes in the integrator 2.3. Release integrator lock 2.4. Return updated routes to update Stack 3. Update routes in Stack 4. Release Stack lock A deadlock may occur if a Normal route update was attemped at the same time an NDP event triggered route update was attempted. With threads T1 and T2: 1) T1 -> A.1, A.2 2) T2 -> B.1 3) T1 -> A.3 (hangs at A.3.1 since Stack lock is taken in step 2) 4) T2 -> B.2 (hangs at B.2.1 since integrator lock is taken in step 1) Test: Existing tests were modified to not provide or expect routing table changes in response to Router and Prefix discovery events.

2019-12-16Implement checks for get/setxattr at the syscall layer.Dean Deng
Add checks for input arguments, file type, permissions, etc. that match the Linux implementation. A call to get/setxattr that passes all the checks will still currently return EOPNOTSUPP. Actual support will be added in following commits. Only allow user.* extended attributes for the time being. PiperOrigin-RevId: 285835159
2019-12-16Fix deadlock in overlay bindYong He
Copy up parent when binding UDS on overlayfs is supported in commit 02ab1f187cd24c67b754b004229421d189cee264. But the using of copyUp in overlayBind will cause sentry stuck, reason is dead lock in renameMu. 1 [Process A] Invoke a Unix socket bind operation renameMu is hold in fs.(*Dirent).genericCreate by process A 2 [Process B] Invoke a read syscall on /proc/task/mounts waitng on Lock of renameMu in fs.(*MountNamespace).FindMount 3 [Process A] Continue Unix socket bind operation wating on RLock of renameMu in fs.copyUp Root cause is recursive reading lock of reanmeMu in bind call trace, if there are writing lock between the two reading lock, then deadlock occured.

2019-12-16Fix UDS bind cause fd leak in goferYong He
After the finalizer optimize in 76039f895995c3fe0deef5958f843868685ecc38 commit, clientFile needs to closed before finalizer release it. The clientFile is not closed if it is created via gofer.(*inodeOperations).Bind, this will cause fd leak which is hold by gofer process.

2019-12-11Add support for TCP_USER_TIMEOUT option.Bhasker Hariharan
The implementation follows the linux behavior where specifying a TCP_USER_TIMEOUT will cause the resend timer to honor the user specified timeout rather than the default rto based timeout. Further it alters when connections are timedout due to keepalive failures. It does not alter the behavior of when keepalives are sent. This is as per the linux behavior. PiperOrigin-RevId: 285099795
