Function Documentation

int compare_gss_ctx	(	hash_buffer_t *	buff1,
		hash_buffer_t *	buff2
	)

compare_gss_ctx: compares the gss_ctx stored in the key buffers.

compare the gss_ctx stored in the key buffers. This function is to be used as 'compare_key' field in the hashtable storing the gss context.

Parameters:

buff1	[IN] first key
buff2	[IN] second key

Returns:

0 if keys are identifical, 1 if they are different.

Definition at line 271 of file AuthGss_HashTable.c.

int display_gss_ctx	(	hash_buffer_t *	pbuff,
		char *	str
	)

display_gss_ctx: displays the gss_ctx stored in the buffer.

displays the gss_ctx stored in the buffer. This function is to be used as 'key_to_str' field in the hashtable storing the gss context.

Parameters:

buff1	[IN] buffer to display
buff2	[OUT] output string

Returns:

number of character written.

Definition at line 294 of file AuthGss_HashTable.c.

int display_gss_svc_data	(	hash_buffer_t *	pbuff,
		char *	str
	)

display_gss_svc_data: displays the gss_svc_data stored in the buffer.

displays the gss_svc__data stored in the buffer. This function is to be used as 'value_to_str' field in the hashtable storing the gss context.

Parameters:

buff1	[IN] buffer to display
buff2	[OUT] output string

Returns:

number of character written.

int Gss_ctx_Hash_Del

(

gss_union_ctx_id_desc *

pgss_ctx

)

Gss_ctx_Hash_Del

This routine removes a state from the Gss ctx hashtable.

Returns:

1 if ok, 0 otherwise.

Definition at line 455 of file AuthGss_HashTable.c.

uint32_t gss_ctx_hash_func	(	hash_parameter_t *	p_hparam,
		hash_buffer_t *	buffclef
	)

gss_ctx_hash_func: computes the hash value for the entry in GSS Ctx cache.

Computes the hash value for the entry in GSS Ctx cache. In fact, it just use addresse as value (identity function) modulo the size of the hash. This function is called internal in the HasTable_* function

Parameters:

hparam	[IN] hash table parameter.
buffcleff	[IN] pointer to the hash key buffer

Returns:

the computed hash value.

		bool_t **	established,
		u_int **	seqlast,
		uint32_t **	seqmask
	)

Gss_ctx_Hash_Get

This routine gets a Gss Ctx from the hashtable and returns a pointers to a the established, seqlast, and seqmask variables of the context.

Returns:

1 if ok, 0 otherwise.

param

)

Gss_ctx_Hash_Init: Init the hashtable for GSS Ctx

Perform all the required initialization for hashtable Gss ctx cache

Returns:

0 if successful, -1 otherwise

void Gss_ctx_Hash_Print

(

void

)

Gss_ctx_Hash_Print: Displays the content of the hash table (for debugging)

Displays the content of the hash table (for debugging).

Returns:

nothing (void function)

Definition at line 503 of file AuthGss_HashTable.c.

int Gss_ctx_Hash_Set	(	gss_union_ctx_id_desc *	pgss_ctx,
		struct svc_rpc_gss_data *	gd
	)

Gss_ctx_Hash_Set

This routine sets a Gss Ctx into the Gss Context's hashtable.

Returns:

1 if ok, 0 otherwise.

Definition at line 339 of file AuthGss_HashTable.c.

uint64_t gss_ctx_rbt_hash_func	(	hash_parameter_t *	p_hparam,
		hash_buffer_t *	buffclef
	)

gss_ctx_rbt_hash_func: computes the rbt value for the entry in GSS Ctx cache.

Computes the rbt value for the entry in GSS Ctx cache. In fact, it just use the address value itself (which is an unsigned integer) as the rbt value. This function is called internal in the HasTable_* function

Parameters:

hparam	[IN] hash table parameter.
buffcleff[in]	pointer to the hash key buffer

Returns:

the computed rbt value.
