2021-09-01Don't use reflection in fpu.alignedBytes.Jamie Liu
reflect.ValueOf takes an interface{}, so when passed a slice the compiler emits a call to runtime.convTslice to heap-allocate a copy of the slice header. PiperOrigin-RevId: 394310052

2021-08-26Centralize TCP timestamp logicTamir Duberstein
Remove freestanding functions that convert time values to raw integers; centralize time->uint32 logic in methods on tcp.endpoint. Importantly, the knowledge that TSVal is in milliseconds now lives in adjacent functions rather than being spread around various files. Incidental cleanup: - Remove unused constant - Remove redundant conversion - Remove redundant parentheses - Add missing error check PiperOrigin-RevId: 393184768

2021-08-24Measure RTT during handshake since Linux does the sameZeling Feng
Some tcp unit tests are affected by this change: - Some retransmission tests assumed RTO=1s when connection is established. This is no longer true because minRTO was set to 3s in tests so now RTO becomes 3s after the first updateRTO call. Set minRTO=1s for these tests. - Some RACK enabled tests are affected because now that RTT is initialized, and the estimated RTT is quite small, spurious TLP might be sent out and causing flakes, introduce an artificial delay for these tests so that the estimated RTT is larger.

2021-08-21platform/kvm: set physical slots without overlappingAndrei Vagin
Right now, the first slot starts with an address of a memory region and its size is faultBlockSize, but the second slot starts with (physicalStart + faultBlockSize) & faultBlockMask. It means they will overlap if a start address of a memory region are not aligned to faultBlockSize. The kernel doesn't allow to add overlapped regions, but we ignore the EEXIST error.

2021-08-20[op] Prevent file leak in MultiGetAttr's error path.Ayush Ranjan
The old implementation was mostly correct but error prone - making way for the issue in question here. In its error path, it would leak the intermediate file being walked. Each return/break needed explicit cleanup. This change implements a more clean way to cleaning up intermediate directories. If the code were to evolve to be more complex, it would still work.
