2022-10-25hash: add local variableGabriel Oginski1-2/+3
The current implmentation of the hash table is not thread-safe. This design leads to a segfault when VPP handling a lot of tunnels for Wireguard, where one thread modify the hash table and other threads starting to lookup at the same time. The fix add a local variable to store how many bits are used by a user object.

2018-06-05VPP API: Memory traceOle Troan1-0/+15
if you plan to put a hash into shared memory, the key sum and key equal functions MUST be set to constants such as KEY_FUNC_STRING, KEY_FUNC_MEM, etc. -lvppinfra is PIC, which means that the process which set up the hash won't have the same idea where the key sum and key compare functions live in other processes.

On deleting sub-interfaces, functions vnet_delete_sub_interface() and vnet_delete_hw_interface() are not cleaning up sub-interface related hash tables and memory properly.

Move the functions hash_set_key_copy() and hash_unset_key_free() which are dupilicated in various tunnel support code modules to hash.h as hash_set_mem_alloc() and hash_unset_mem_free() to be used by all. Change-Id: I40723cabe29072ab7feb1804c221f28606d8e4fe Signed-off-by: John Lo <loj@cisco.com>
