2020-01-30Fix for panic in endpoint.Close().Bhasker Hariharan
When sending a RST on shutdown we need to double check the state after acquiring the work mutex as the endpoint could have transitioned out of a connected state from the time we checked it and we acquired the workMutex. I added two tests but sadly neither reproduce the panic. I am going to leave the tests in as they are good to have anyway. PiperOrigin-RevId: 292393800

Splice must not allow negative offsets. Writes also must not allow offset + size to overflow int64. Reads are similarly broken, but not just in splice (b/148095030). Reported-by: syzbot+0e1ff0b95fb2859b4190@syzkaller.appspotmail.com PiperOrigin-RevId: 292361208

2020-01-28Prevent arbitrary size allocation when sending UDS messages.Dean Deng
Currently, Send() will copy data into a new byte slice without regard to the original size. Size checks should be performed before the allocation takes place. Note that for the sake of performance, we avoid putting the buffer allocation into the critical section. As a result, the size checks need to be performed again within Enqueue() in case the limit has changed. PiperOrigin-RevId: 292058147
