-Subject: [PATCH] zebra: Store the sequence number to use as part of the
- dp_info
-
-Store and use the sequence number instead of using what is in
-the `struct nlsock`.  Future commits are going away from storing
-the `struct nlsock` and the copy of the nlsock was guaranteeing
-unique sequence numbers per message.  So let's store the
-sequence number to use instead.

-Subject: [PATCH] zebra: Remove `struct nlsock` from dataplane information and
- use `int fd`
-
-Store the fd that corresponds to the appropriate `struct nlsock` and pass
-that around in the dplane context instead of the pointer to the nlsock.
-Modify the kernel_netlink.c code to store in a hash the `struct nlsock`
-with the socket fd as the key.
-
-Why do this?  The dataplane context is used to pass around the `struct nlsock`
-but the zebra code has a bug where the received buffer for kernel netlink
-messages from the kernel is not big enough.  So we need to dynamically
-grow the receive buffer per socket, instead of having a non-dynamic buffer
-that we read into.  By passing around the fd we can look up the `struct nlsock`
-that will soon have the associated buffer and not have to worry about `const`
-issues that will arise.

-Subject: [PATCH] zebra: Make netlink buffer reads resizeable when needed
-
-Currently when the kernel sends netlink messages to FRR
-the buffers to receive this data is of fixed length.
-The kernel, with certain configurations, will send
-netlink messages that are larger than this fixed length.
-This leads to situations where, on startup, zebra gets
-really confused about the state of the kernel.  Effectively
-the current algorithm is this:
-
-read up to buffer in size
-while (data to parse)
-     get netlink message header, look at size
-        parse if you can
-
-The problem is that there is a 32k buffer we read.
-We get the first message that is say 1k in size,
-subtract that 1k to 31k left to parse.  We then
-get the next header and notice that the length
-of the message is 33k.  Which is obviously larger
-than what we read in.  FRR has no recover mechanism
-nor is there a way to know, a priori, what the maximum
-size the kernel will send us.
-
-Modify FRR to look at the kernel message and see if the
-buffer is large enough, if not, make it large enough to
-read in the message.
-
-This code has to be per netlink socket because of the usage
-of pthreads.  So add to `struct nlsock` the buffer and current
-buffer length.  Growing it as necessary.
-
-Fixes: #10404

-Subject: [PATCH] ospf6d: fix infinite loop when adding ASBR route
-
-Commit 8f359e1593c414322 removed a check that prevented the same route
-from being added twice. In certain topologies, that change resulted in
-the following infinite loop when adding an ASBR route:
-
-ospf6_route_add
- ospf6_top_brouter_hook_add
-  ospf6_abr_examin_brouter
-   ospf6_abr_examin_summary
-    ospf6_route_add
-     (repeat until stack overflow)
-
-Revert the offending commit and update `ospf6_route_is_identical()` to
-not do comparison using `memcmp()`.
