| * | | | | | | | | | | | | | | | | | | | | | | | QUIC: removed outdated TODOs.Vladimir Homutov2020-08-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The logical quic connection state is tested by handler functions that process corresponding types of packets (initial/handshake/application). The packet is declined if state is incorrect. No timeout is required for the input queue.
| * | | | | | | | | | | | | | | | | | | | | | | | QUIC: added version negotiation support.Vladimir Homutov2020-08-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If a client attemtps to start a new connection with unsupported version, a version negotiation packet is sent that contains a list of supported versions (currently this is a single version, selected at compile time).
| * | | | | | | | | | | | | | | | | | | | | | | | HTTP/3: special handling of client errors in the upstream module.Roman Arutyunyan2020-08-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function ngx_http_upstream_check_broken_connection() terminates the HTTP/1 request if client sends eof. For QUIC (including HTTP/3) the c->write->error flag is now checked instead. This flag is set when the entire QUIC connection is closed or STOP_SENDING was received from client.
| * | | | | | | | | | | | | | | | | | | | | | | | HTTP/3: request more client body bytes.Roman Arutyunyan2020-08-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously the request body DATA frame header was read by one byte because filters were called only when the requested number of bytes were read. Now, after 08ff2e10ae92 (1.19.2), filters are called after each read. More bytes can be read at once, which simplifies and optimizes the code. This also reduces diff with the default branch.

| * | | | | | | | | | | | | | | | | | | | | | | | QUIC: handling packets with send time equal to lost send time.Sergey Kandaurov2020-08-19

For implementation details, see quic-recovery draft 29, appendix A.10.
| * | | | | | | | | | | | | | | | | | | | | | | | QUIC: sending probe packets on PTO timer expiration.Sergey Kandaurov2020-08-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PTO handler is split into separate PTO and loss detection handlers that operate interchangeably depending on which timer should be set. The present ngx_quic_lost_handler is now only used for packet loss detection. It replaces ngx_quic_pto_handler if there are packets preceeding largest_ack. Once there is no more such packets, ngx_quic_pto_handler is installed again. Probes carry unacknowledged data previously sent in the oldest packet number, one per each packet number space. That is, it could be up to two probes. PTO backoff is now increased before scheduling next probes.
| * | | | | | | | | | | | | | | | | | | | | | | | QUIC: changed ctx->largest_ack initial value to type maximum.Sergey Kandaurov2020-08-18

For example, only Initial packets were acknowledged in handshake.

| * | | | | | | | | | | | | | | | | | | | | | | | | QUIC: coalesce neighbouring stream send buffers.Roman Arutyunyan2020-08-18

The following changes were made in the stream send code: - ngx_quic_stream_send_chain() no longer calls ngx_quic_stream_send() and got a separate implementation that coalesces neighbouring buffers into a single frame - the new ngx_quic_stream_send_chain() respects the limit argument, which fixes sendfile_max_chunk and limit_rate - ngx_quic_stream_send() is reimplemented to call ngx_quic_stream_send_chain() - stream frame size limit is moved out to a separate function ngx_quic_max_stream_frame() - flow control is moved out to a separate function ngx_quic_max_stream_flow() - ngx_quic_stream_send_chain() is relocated next to ngx_quic_stream_send()

This function is responsible for creating streams with lower ids as well. Also, simplified and fixed initial data buffering in ngx_quic_handle_stream_frame(). It is now done before calling the initial handler as the handler can destroy the stream.
| * | | | | | | | | | | | | | | | | | | | | | | | | QUIC: fixed ngx_http_test_reading() for QUIC streams.Roman Arutyunyan2020-08-11

The reason for this error was that a QUIC stream has no socket descriptor. However checking for eof is not the right thing to do for an HTTP/3 QUIC stream since HTTP/3 clients are expected to shut down the write end of the stream after sending the request. Now the function handles QUIC streams separately. It checks if c->read->error is set. The error flags for c->read and c->write are now set for all streams when closing the QUIC connection instead of setting the pending_eof flag.

To detect this, ngx_quic_find_stream() is used to check that it still exists. Previously, a stream id was passed to this routine off the frame structure. In case of stream cleanup, it is freed along with other frames belonging to the stream on cleanup. Then, a cleanup handler reuses last frames to update MAX_STREAMS and serve other purpose. Thus, ngx_quic_find_stream() is passed a reused frame with zeroed out part pointed by stream_id. If a stream with id 0x0 still exists, this leads to use-after-free.

Also, the following is changed for data arriving to non-existing streams: - if a stream was already closed, such data is ignored - when creating a new stream, all streams of the same type with lower ids are created too

The enum is visible from quic event headers and eventually pollutes ngx_core.h. The fix is to limit including headers to compile units that are real consumers.

In the QUIC code only verify that some protocol was selected and trigger an error otherwise.
| * | | | | | | | | | | | | | | | | | | | | | | | | QUIC: fixed stream read event log.Roman Arutyunyan2020-07-18

During the handshake, a server cannot send more than three times the data it receives; clients that initiate new connections or migrate to a new network path are limited.
| * | | | | | | | | | | | | | | | | | | | | | | | | QUIC: added limit of queued data.Vladimir Homutov2020-07-16
