p_key is a parameter, and it is char[].
It shouldn't be freed here.

I don't see this. st_delete() call: if (st_delete(p_domain_imp->p_hash, (void *)&p_key, (void *)&p_prev_val)) { ... free(p_key); ... } overwrites those value by pointers to key values stored in the hash table (then 1 is returned).

Oh, you're right. I was following the function parameter itself and missed this part. -- Yevgeny > Sasha > >> >> Signed-off-by: Yevgeny Kliteynik<kliteyn-LDSdmyG8hGV8YrgS2mwiifqBs+8SCbDb@public.gmane.org> >> --- >> opensm/opensm/osm_db_files.c | 1 - >> 1 files changed, 0 insertions(+), 1 deletions(-) >> >> diff --git a/opensm/opensm/osm_db_files.c b/opensm/opensm/osm_db_files.c >> index dd9f772..c475004 100644 >> --- a/opensm/opensm/osm_db_files.c >> +++ b/opensm/opensm/osm_db_files.c >> @@ -582,7 +582,6 @@ int osm_db_delete(IN osm_db_domain_t * p_domain, IN char *p_key) >> p_key, p_domain_imp->file_name, p_prev_val); >> res = 1; >> } else { >> - free(p_key); >> free(p_prev_val); >> res = 0; >> } >> -- >> 1.6.2.4 >> > -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html ^ permalink raw reply [flat|nested] 3+ messages in thread
