ca0b5e0c88 Make filtermaxsize, parentretries, delimchar and maxseg per service 
Like the timeouts, each service now keeps the values given before it
instead of reading the global ones while its connections run. setopts()
takes the service's maxseg. The TLS handshakes wait the service's
CONNECT_TO, kept in its SSL configuration, rather than the global one.

3d5da0105d Fix the build with MSVC: nssocket() a function everywhere 
Outside Linux nssocket() was a macro, and two of its callers have #ifdef
WITH_UN among its arguments. Preprocessor directives in macro arguments
are undefined behaviour: gcc and clang take them, MSVC does not. It is a
function on every system now.

626aac16bc splice() per direction, pipes per connection, automatic mode 
-s takes the directions to splice: -s1 what the server sends (downloads),
-s2 what the client sends (uploads), -s3 both. -s alone (-s7) splices both
only where it pays, as -s5 and -s6 do for one direction:
- a body of known length is spliced if at least 16K of it is left to read
  once what is already buffered is counted, so an answer read whole with
  its headers is just copied;
- a stream of unknown length starts copied, is spliced after 2 reads in a
  row of at least 16K, and goes back to copying after 3 splices in a row
  of less than 4K, once its pipe is empty.

Pipes are made when a direction first splices and kept with the
connection for its next mappings, so a kept-alive connection no longer
makes and closes two pipes per request; one left holding data by an
error or a timeout is closed. The direction not spliced keeps its buffer.

Before, -s spliced both directions and every mapping made both pipes,
which made small answers slower than without splice: with kept-alive
50K answers 2 pipe2() and 4 close() per request, now none.

Also corrects the default buffer size in the -b help (65536 for TCP).

b4f5ffbf8c Fix missing device binding for few cases 2026-10-10 17:38:44 +03:00

cd34fd45d5 Take another local port when the one bound cannot reach the destination 
extport binds a local port out of its range and connects from it. A port
which is free to bind may still be half of a pair which is closing from an
earlier connection to the same destination, and Windows fails the connect
with WSAEADDRINUSE where other systems fail the bind and fall back. The
request then failed with error 13 for a reason another port would have
avoided, which is what the range is searched for in the first place.

Retry the connect with another port from the range. Only for that error, so
a destination which is simply unreachable still costs one attempt, and out of
the same ten tries the bind already spends, so the attempts parentretries
makes are not multiplied. EADDRINUSE joins the errno values proxy.h maps to
their Winsock numbers, without which the test would never match on Windows.

parent_ports gave its three services one window between them, which is how
the case met the collision on the Windows runner. Each has its own now.

Use unix:/path/to/socket, e.g.

tcppm 1234 unix:/path/to/socket 1234

Under linux abstract sockets are supported with '@' prefix, e.g.

parent 1000 http unix:@virtual.3proxy.socket 1111

Destination port numbers are not used in tcppm/parent, but you must specify any positive value to match the syntaxis.
