2018-06-26client: flush buffered SSL output when tearing down client ustreamJo-Philipp Wich
When the outer SSL ustream triggers a change notification due to encountering EOF, the inner connection ustream might still have pending data buffered. Previously, such a condition led to truncated files delivered by uhttpd via HTTPS and could be triggered by requesting large resources via slow network links. Mitigate the problem by propagating the EOF status indicator from the outer ustream to the inner one and by deferring the client connection shutdown until the inner ustream output buffer has been completely drained.

2015-10-08fix chunked transfer encoding in keepalive modeJo-Philipp Wich
The two commits 5162e3b0ee7bd1d0fd6e75e1ca7993a1834b5291 "allow request handlers to disable chunked reponses" and 618493e378e2239f0d30902e47adfa134e649fdc "file: disable chunked encoding for file responses" broke the chunked transfer encoding handling for proc responses in keep-alive connections that followed a file response with http status 204 or 304. The effect of this bug is that cgi responses following a 204 or 304 one where sent neither in chunked encoding nor with a content-length header, causing browsers to stall until the keep alive timeout was reached. Fix the logic flaw by inverting the chunk prevention flag in the client state and by testing the chunked encoding preconditions every time instead of once upon client (re-)initialization.

2014-10-27client: store http code of last emitted responseJo-Philipp Wich
Certain response types (notably 204 and 304) require a slightly different handling like emitting the response body entirely, therfore record the last code to act on it in the appropriate places. Signed-off-by: Jo-Philipp Wich <jow@openwrt.org>
2014-06-10ubus: add CORS header supportJo-Philipp Wich
In order to support cross-domain AJAX requests to the /ubus endpoint we need to implement the Cross-Origin Resource Sharing (CORS) spec in the ubus plugin. - Implement a new option "-X" to enable CORS support in ubus - Implement rudimentary support for "OPTIONS" HTTP requests - Implement essential CORS headers the ubus plugin The current CORS response headers merely reflect the request headers sent by the client, this way any requesting origin is automatically allowed. Cross-domain cookies (Access-Control-Allow-Credentials) are unconditionally enabled. Restricting permitted origins and toggle the credential accepting can be made configurable in a future commit to allow more fine grained control over permitted AJAX clients.

2013-11-21uhttpd: fix crashes in the ubus pluginFelix Fietkau
The ubus plugin calls blocking ubus functions that loop back into uloop_run. Protect the client data structure with refcounting to ensure that the outer uloop_run call does not clean up the data that the inner uloop_run call is still processing. Signed-off-by: Felix Fietkau <nbd@openwrt.org>
