Function Documentation

FPSpotlightCloseQuery()

unsigned int FPSpotlightCloseQuery	(	CONN *	conn,
		uint16_t	vid,
		uint64_t	ctx
	)

Send a closeQueryForContext: Spotlight RPC for the given context.

FPSpotlightDrainResults()

unsigned int FPSpotlightDrainResults	(	CONN *	conn,
		uint16_t	vid,
		uint64_t	ctx,
		int *	total_results_out
	)

Drain Spotlight query results until the server reports complete.

Loops fetchQueryResultsForContext: until the embedded status field is 0 (search complete) or the loop guard expires. Sums the kMDQueryResultIndices array length from each reply.

The SPOTLIGHT_CMD_RPC reply envelope has 4 leading bytes before the marshalled DALLOC_CTX (matches the server's sl_pack(reply, rbuf+4)).

FPSpotlightFetchPropertiesWithLargeTOCIndex()

unsigned int FPSpotlightFetchPropertiesWithLargeTOCIndex	(	CONN *	conn,
		uint16_t	vid
	)

Send a valid fetchPropertiesForContext: request whose first complex tag references a far out-of-range TOC index.

FPSpotlightFetchPropertiesWithShrunkTOC()

unsigned int FPSpotlightFetchPropertiesWithShrunkTOC	(	CONN *	conn,
		uint16_t	vid
	)

Send an otherwise-valid fetchPropertiesForContext: request whose TOC tag claims no usable complex-object entries.

FPSpotlightOpen()

unsigned int FPSpotlightOpen	(	CONN *	conn,
		uint16_t	vid,
		char *	vol_path_out,
		size_t	vol_path_buflen
	)

Send SPOTLIGHT_CMD_OPEN and optionally extract the volume path.

On success the reply layout is vid (4) + zero (4) + NUL-terminated path starting at dsi->data + 8; if vol_path_out is non-NULL the path is copied via strlcpy bounded by vol_path_buflen.

FPSpotlightOpenQuery()

unsigned int FPSpotlightOpenQuery	(	CONN *	conn,
		uint16_t	vid,
		const char *	query_dsl,
		uint64_t	ctx
	)

Build and send an openQueryWithParams:forContext: Spotlight RPC.

Mirrors sl_rpc_openQuery's expectations exactly. The outer DALLOC_CTX holds one sl_array_t (outer_array) with two children: [0] args : sl_array_t with three elements [0] = "openQueryWithParams:forContext:" (char *) [1] = ctx1 (uint64_t) [2] = ctx2 (uint64_t) [1] params : sl_dict_t — key/value pairs (kMDQueryString → DSL, kMDAttributeArray → sl_array_t, kMDScopeArray → char *)

Stack-local scalars use dalloc_add_copy so the value is memcpy'd into a freshly-talloc'd chunk; dalloc_add only captures a pointer.

Both ctx values are needed because sl_rpc_openQuery dereferences both via dalloc_get(query, "DALLOC_CTX", 0, "DALLOC_CTX", 0, "uint64_t", 1) and "uint64_t", 2.

FPSpotlightRPCWithLargeInt64Count()

unsigned int FPSpotlightRPCWithLargeInt64Count	(	CONN *	conn,
		uint16_t	vid
	)

Send the companion advisory PoC: one INT64 tag claiming a huge count.

spotlight_pack_fetch_properties_rpc()

static int spotlight_pack_fetch_properties_rpc ( char *  rpcbuf )

static

spotlight_send()

static unsigned int spotlight_send ( CONN *  conn, uint16_t  vid, uint32_t  subcmd, const uint8_t *  rpc_buf, size_t  rpc_len  )

static

Wrap an AFP_SPOTLIGHT_PRIVATE request and ship it on the DSI.

Builds the 24-byte SPOTLIGHT_PRIVATE envelope (cmd byte, vid, reserved, subcmd, reserved, padding) and appends rpc_buf, then sends and receives the reply via the existing my_dsi_* helpers.

spotlight_test_get_le32()

static uint32_t spotlight_test_get_le32 ( const char *  buf, size_t  offset  )

static

spotlight_test_pack_tag()

static uint64_t spotlight_test_pack_tag ( uint16_t  type, uint16_t  size_or_count, uint32_t  val  )

static

spotlight_test_put_le32()
