2022-02-03HTTP/2: made it possible to flush response headers (ticket #1743).Maxim Dounin1-0/+2
Response headers can be buffered in the SSL buffer. But stream's fake connection buffered flag did not reflect this, so any attempts to flush the buffer without sending additional data were stopped by the write filter. It does not seem to be possible to reflect this in fc->buffered though, as we never known if main connection's c->buffered corresponds to the particular stream or not. As such, fc->buffered might prevent request finalization due to sending data on some other stream. Fix is to implement handling of flush buffers when the c->need_flush_buf flag is set, similarly to the existing last buffer handling. The same flag is now used for UDP sockets in the stream module instead of explicit checking of c->type.
2021-04-08Introduced the "keepalive_time" directive.Maxim Dounin1-0/+2
Similar to lingering_time, it limits total connection lifetime before keepalive is switched off. The default is 1 hour, which is close to the total maximum connection lifetime possible with default keepalive_requests and keepalive_timeout.
2018-10-03Upstream: proxy_socket_keepalive and friends.Vladimir Homutov1-1/+13
The directives enable the use of the SO_KEEPALIVE option on upstream connections. By default, the value is left unchanged.

2018-02-22Generate error for unsupported IPv6 transparent proxy.Roman Arutyunyan1-0/+9
On some platforms (for example, Linux with glibc 2.12-2.25) IPv4 transparent proxying is available, but IPv6 transparent proxying is not. The entire feature is enabled in this case and NGX_HAVE_TRANSPARENT_PROXY macro is set to 1. Previously, an attempt to enable transparency for an IPv6 socket was silently ignored in this case and was usually followed by a bind(2) EADDRNOTAVAIL error (ticket #1487). Now the error is generated for unavailable IPv6 transparent proxy.
2016-09-15Stream: filters.Roman Arutyunyan1-0/+1
2016-08-22Events: fixed setting of IP_BIND_ADDRESS_NO_PORT/SO_REUSEADDR.Ruslan Ermilov1-1/+1
The IP_BIND_ADDRESS_NO_PORT option is set on upstream sockets if proxy_bind does not specify a port. The SO_REUSEADDR option is set on UDP upstream sockets if proxy_bind specifies a port. Due to checking of the wrong port, IP_BIND_ADDRESS_NO_PORT was never set, and SO_REUSEPORT was always set.
2016-06-20Stream: set SO_REUSEADDR for UDP upstream sockets.Roman Arutyunyan1-1/+25
The option is only set if the socket is bound to a specific port to allow several such sockets coexist at the same time. This is required, for example, when nginx acts as a transparent proxy and receives two datagrams from the same client in a short time. The feature is only implemented for Linux.
2016-06-20Set IP_BIND_ADDRESS_NO_PORT socket option for upstream sockets.Andrei Belov1-0/+26
2015-12-18Upstream: the "transparent" parameter of proxy_bind and friends.Roman Arutyunyan1-0/+103
This parameter lets binding the proxy connection to a non-local address. Upstream will see the connection as coming from that address. When used with $remote_addr, upstream will accept the connection from real client address. Example: proxy_bind $remote_addr transparent;

2015-04-22Removed the obsolete aio module.Ruslan Ermilov1-3/+1
2014-09-01Events: removed broken thread support from posted events.Valentin Bartenev1-11/+0
It's mostly dead code. And the idea of thread support for this task has been deprecated.
2014-03-06Fixed format specifier in logging of "c->number".Sergey Kandaurov1-1/+1
2013-09-04Win32: MinGW GCC compatibility.Maxim Dounin1-1/+1
Several warnings silenced, notably (ngx_socket_t) -1 is now checked on socket operations instead of -1, as ngx_socket_t is unsigned on win32 and gcc complains on comparison. With this patch, it's now possible to compile nginx using mingw gcc, with options we normally compile on win32.
2013-03-27Event connect: don't penalize AF_INET6 connections.Maxim Dounin1-1/+1
Problems with setsockopt(TCP_NODELAY) and setsockopt(TCP_NOPUSH), as well as sendfile() syscall on Solaris, are specific to UNIX-domain sockets. Other address families, i.e. AF_INET and AF_INET6, are fine.
2012-01-30Fixed error handling in ngx_event_connect_peer().Maxim Dounin1-6/+5
Previously if ngx_add_event() failed a connection was freed two times (once in the ngx_event_connect_peer(), and again by a caller) as pc->connection was left set. Fix is to always use ngx_close_connection() to close connection properly and set pc->connection to NULL on errors. Patch by Piotr Sikora.
