Follow-up Comment #3:
Cui, since you did not go into detail on Frédéric's questions and I think
Frédéric is right here, I'm closing this as invalid.
Please feel free to correct me.
Here's how I see it with your example:
- 7000 bytes are received
- sock->lastdata points to that netbuf
- 4096 bytes are copied to user memory, sock->lastoffset=4096
- next call to recvfrom
- sock->lastdata is != NULL
- 2904 bytes are copied to user memory,
- sock->lastdata is set to NULL, sock->lastoffset is set to 0
Can't see a problem here.
