2021-01-22Detect failures in forked functionFabricio Voznika
EXPECT*/ASSERT* functions are not async-signal-safe and should not be called from the function passed to InForkedProcess. However, these happen accidentally sometimes but do no cause InForkedProcess to fail. Detect and notify in such cases. PiperOrigin-RevId: 353354540

2021-01-22Pass RouteInfo to the route resolve callbackGhanan Gowripalan
The route resolution callback will be called with a stack.ResolvedFieldsResult which will hold the route info so callers can avoid attempting resolution again to check if a previous resolution attempt succeeded or not. Test: integration_test.TestRouteResolvedFields PiperOrigin-RevId: 353319019

2021-01-21Do not cache remote link address in RouteGhanan Gowripalan
...unless explicitly requested via ResolveWith. Remove cancelled channels from pending packets as we can use the link resolution channel in a FIFO to limit the number of maximum pending resolutions we should queue packets for. This change also defers starting the goroutine that handles link resolution completion to when link resolution succeeds, fails or gets cancelled due to the max number of pending resolutions being reached. Fixes #751. PiperOrigin-RevId: 353130577

2021-01-21Fix ownership change logicFabricio Voznika
Previously fsgofer was skipping chown call if the uid and gid were the same as the current user/group. However, when setgid is set, the group may not be the same as the caller. Instead, compare the actual uid/gid of the file after it has been created and change ownership only if needed. Updates #180 PiperOrigin-RevId: 353118733
