LDPd needs some cleanup to support a snap package.

Part of the snap security policy is that they can’t write outside of their $SNAP_DATA (which is a unknown location at compile time)

Other daemons are modified to support an option for vty socket location override.

See here
https://github.com/opensourcerouting/cumulus-private_quagga/commit/9c9af95394546560c80280a14fe88fd5161d1536

Running the LDP, I see it still uses a socket at /run/ldpd.sock - which is the LDPD_SOCKET
It's not clear (to me) on what this socket is used for. I assume this is for the communication between the different ldp processes?

Any suggestion on adding a CLI option to override this (similar to —vty_socket ?)

Martin can I get a clarification? I see the patch 9c9af95 above, is that what you want to be added in? Do you just need a bit of testing to make sure it works as expected?

Sorry, was traveling.

I saw the patches from Renato and I think they are what I need/want. But
I need to verify and test them in detail.
Will have a branch to merge by end of weekend latest.

So hold off on this one for now.

This commit ensures proper cleanup by deleting the gm_join_list when a PIM interface is deleted. The gm_join_list was previously not being freed, causing a memory leak.

allocation(s). *********************************************************************************** ``` Signed-off-by: Keelan Cannoo <keelan.cannoo@icloud.com> (cherry picked from commit 24379f0)

This commit ensures proper cleanup by deleting the gm_join_list when a PIM interface is deleted. The gm_join_list was previously not being freed, causing a memory leak. The ASan leak log for reference: ``` *********************************************************************************** Address Sanitizer Error detected in
