Hi guys,
I'm testing the sr mpls, and there is a small cache release more than once.
How should we avoid this ? My debug info is shown below:
create_sl (mpls_sr_policy_t * sr_policy, mpls_label_t * sl, u32 weight)
{
mpls_sr_main_t *sm = &sr_mpls_main;
mpls_sr_sl_t *segment_list;
pool_get (sm->sid_lists, segment_list);
memset (segment_list, 0, sizeof (*segment_list));
vec_add1 (sr_policy->segments_lists, segment_list - sm->sid_lists);
/* Fill in segment list */
segment_list->weight =
(weight != (u32) ~ 0 ? weight : SR_SEGMENT_LIST_WEIGHT_DEFAULT);
segment_list->segments = vec_dup (sl);
fib_route_path_t path = {
.frp_proto = DPO_PROTO_MPLS,
.frp_sw_if_index = ~0,
.frp_fib_index = 0,
.frp_weight = segment_list->weight,
.frp_flags = FIB_ROUTE_PATH_FLAG_NONE,
.frp_label_stack = NULL,
.frp_local_label = sl[0],
};
vec_add (path.frp_label_stack, sl + 1, vec_len (sl) - 1);
fib_route_path_t *paths = NULL;
vec_add1 (paths, path);
mpls_eos_bit_t eos;
FOR_EACH_MPLS_EOS_BIT (eos)
{
/* *INDENT-OFF* */
fib_prefix_t pfx = {
.fp_len = 21,
.fp_proto = FIB_PROTOCOL_MPLS,
.fp_label = sr_policy->bsid,
.fp_eos = eos,
.fp_payload_proto = DPO_PROTO_MPLS,
};
/* *INDENT-ON* */
fib_table_entry_path_add2 (0,
&pfx,
FIB_SOURCE_SR,
(sr_policy->type == SR_POLICY_TYPE_DEFAULT ?
FIB_ENTRY_FLAG_NONE :
FIB_ENTRY_FLAG_MULTICAST), paths);
}
vec_free (paths);
return segment_list;
}
In this function,path.frp_label_stack alloc only one memory, but be used many
times with 'fib_table_entry_path_add2 '. When we delete
,'fib_path_ext_list_remove ' would bw call many times, then repeated memory
releaseļ¼and can't be detected.
void
fib_path_ext_list_remove (fib_path_ext_list_t *list,
fib_path_ext_type_t ext_type,
const fib_route_path_t *rpath)
{
fib_path_ext_t *path_ext;
path_ext = fib_path_ext_list_find(list, ext_type, rpath);
if (NULL != path_ext)
{
/*
* delete the element moving the remaining elements down 1 position.
* this preserves the sorted order.
*/
vec_free(path_ext->fpe_label_stack);
vec_delete(list->fpel_exts, 1, (path_ext - list->fpel_exts));
}
}
Actual operation situation:

Backtrace stopped: previous frame inner to this frame (corrupt stack?)

that the same offset has been stored 2 times , It is also verified that the
memory is repeatedly released.
