  53. names when sending to FastCGI, SCGI, and uwsgi backends, in the

  55. of the "$http_...", "$sent_http_...", "$sent_trailer_...",
  56. "$upstream_http_...", and "$upstream_trailer_..." variables.
  57. *) Bugfix: if there were multiple "Vary" header lines in the backend
  58. response, nginx only used the last of them when caching.
  59. *) Bugfix: if there were multiple "WWW-Authenticate" header lines in the

  91. changed to 2 megabytes.
  92. *) Feature: the "proxy_half_close" directive in the stream module.

  102. proxied backend nginx might nevertheless cache the connection.
  103. Thanks to Awdhesh Mathpal.
  104. *) Bugfix: invalid headers from backends were logged at the "info" level
  105. instead of "error"; the bug had appeared in 1.21.1.

  107. directive.

  126. newer, did not affect loading of the server certificates when set
  127. with "@SECLEVEL=N" in the "ssl_ciphers" directive.
  128. *) Bugfix: SSL connections with gRPC backends might hang if select,
  129. poll, or /dev/poll methods were used.

  934. *) Feature: variables support in the stream module.
  935. *) Feature: the ngx_stream_map_module.
  936. *) Feature: the ngx_stream_return_module.

  939. *) Feature: now nginx uses the IP_BIND_ADDRESS_NO_PORT socket option
  940. when available.
  941. *) Bugfix: a segmentation fault might occur in a worker process when
  942. using HTTP/2 and the "proxy_request_buffering" directive.

  944. requests passed to backends, including requests without body, when
  945. using HTTP/2.
  946. *) Bugfix: "http request count is zero" alerts might appear in logs when
  947. using HTTP/2.
  948. *) Bugfix: unnecessary buffering might occur when using the "sub_filter"

  951. *) Security: a segmentation fault might occur in a worker process while
  952. writing a specially crafted request body to a temporary file

  980. HTTP/2 clients when using client certificates.
  981. *) Change: HTTP/2 clients can now start sending request body
  982. immediately; the "http2_body_preread_size" directive controls size of

  1010. *) Change: non-idempotent requests (POST, LOCK, PATCH) are no longer
  1011. passed to the next server by default if a request has been sent to a
  1012. backend; the "non_idempotent" parameter of the "proxy_next_upstream"

  1020. appear in logs when using the "sendfile" and "aio" directives with
  1021. subrequests.
  1022. *) Bugfix: "zero size buf in output" alerts might appear in logs if
  1023. caching was used and a client closed a connection prematurely.
  1024. *) Bugfix: connections with clients might be closed needlessly if
  1025. caching was used.
  1026. Thanks to Justin Li.
  1027. *) Bugfix: nginx might hog CPU if the "sendfile" directive was used on
  1028. Linux or Solaris and a file being sent was changed during sending.
  1029. *) Bugfix: connections might hang when using the "sendfile" and "aio
  1030. threads" directives.
  1031. *) Bugfix: in the "proxy_pass", "fastcgi_pass", "scgi_pass", and

  1051. not delete "Last-Modified" and "ETag" header lines from error
  1052. responses.
  1053. *) Workaround: "called a function you should not call" and "shutdown
  1054. while in init" messages might appear in logs when using OpenSSL
  1055. 1.0.2f.
  1056. *) Bugfix: invalid headers might be logged incorrectly.

  1069. cause segmentation fault in a worker process (CVE-2016-0742).
  1070. *) Security: use-after-free condition might occur during CNAME response
  1071. processing if the "resolver" directive was used, allowing an attacker
  1072. who is able to trigger name resolution to cause segmentation fault in
  1073. a worker process, or might have potential other impact
  1074. (CVE-2016-0746).
  1075. *) Security: CNAME resolution was insufficiently limited if the
  1076. "resolver" directive was used, allowing an attacker who is able to
  1077. trigger arbitrary name resolution to cause excessive resource
  1078. consumption in worker processes (CVE-2016-0747).
