Datachannel streams should be larger than u16
Chrome canary is sending us this: a=sctpmap:5000 webrtc-datachannel 65536 And we are responding with a=sctpmap:5000 webrtc-datachannel 0 because we are storing this value in 16 bits. We should move to a larger unsigned type.
Via correspondence with Jesup over email it appears that we should be limiting this to MAX_NUM_STREAMS instead. This value is defined in DataChannelProtocol.h #define MAX_NUM_STREAMS (2048) So I think we should be reflecting the value of streams unless it is greater than MAX_NUM_STREAMS, in which case we should return the MAX_NUM_STREAMS value. Perhaps I should also be checking for < 1 and setting to 1 in that case as well.
Comment on attachment 819229 [details] [diff] [review] Datachannel streams should be kept in the range 1 to MAX_NUM_STREAMS Tested by building with WEBRTC_DATACHANNEL_STREAMS_DEFAULT to 65536.
