The reason for the erratic behavior was that the tcp implementation silently drops window update messages after noting the update but without triggering any data send event. Before the new TCP patches were applied, the implementation relied on a retransmission timeout to trigger a send event after a window update. One of the new patches dealing with the ideal timer changed the semantic of the restransmit function call and caused the behavior witnessed. But a retransmission timeout is not the correct solution to window update. In fact a retransmission is not a desired effect of window update. So in the patch attached, I have changed the behavior of the implementation to immediately acknowledge the window update (along with data from SendQueue) and thus solving the problem of complete halt in data transmission. The patch also has the changes re-implemented that were reverted back but had nothing to do with the issue at hand. For the time being, I have also removed the "ideal timer" part from the patch (although it wasn't creating any conflict). I initially decided to implement the ideal timer using the same timer used for retransmission to avoid adding an additional timer. But as I have seen, it can be problematic. So I will be re-implementing the ideal timer and thus it was not included in this patch. Signed-off-by: Augustin Cavalier <waddlesplash@gmail.com> Fixes #13704.
Haiku
Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs
Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.
Goals
- Sensible defaults with minimal configuration required.
- Clean, clear, concise code.
- Unified desktop environment.
Trying Haiku
Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.
