Function Documentation

fr_bio_haproxy_alloc()

fr_bio_t* fr_bio_haproxy_alloc	(	TALLOC_CTX *	ctx,
		fr_bio_cb_funcs_t *	cb,
		fr_bio_t *	next
	)

Allocate an haproxy bio.

Here is the call graph for this function:

fr_bio_haproxy_info()

fr_bio_haproxy_info_t const* fr_bio_haproxy_info

(

fr_bio_t *

bio

)

Get client information from the haproxy bio.

Definition at line 253 of file haproxy.c.

fr_bio_haproxy_read()

static ssize_t fr_bio_haproxy_read ( fr_bio_t *  bio, void *  packet_ctx, void *  buffer, size_t  size  )

static

Read from the next bio, and determine if we have an haproxy header.

Definition at line 189 of file haproxy.c.

Here is the call graph for this function:

Here is the caller graph for this function:

fr_bio_haproxy_read_next()

static ssize_t fr_bio_haproxy_read_next ( fr_bio_t *  bio, UNUSED void *  packet_ctx, void *  buffer, size_t  size  )

static

Satisfy reads from the "next" bio.

The caveat is that there may be data left in our buffer which is needed for the application. We can't unchain ourselves until we've returned that data to the application, and emptied our buffer.

fr_bio_haproxy_v1()

static ssize_t fr_bio_haproxy_v1 ( fr_bio_haproxy_t *  my )

static

Parse the haproxy header, version 1.
