@kishorekunal01 , can you improve code coverage by add new test case? |
| void NetDispatcher::registerRawMessageHandler(int nlmsg_type, NetMsg *callback) | ||
| { | ||
| if (m_rawhandlers.find(nlmsg_type) != m_rawhandlers.end()) | ||
| throw "Trying to registered on already registerd netlink message"; |

better to throw specific exception type like runtime_error instead of string literals.

This is similar to the method registerMessageHandler. Hence similar error handling is done.
| m_handlers.erase(it); | ||

is m_rawhandlers protected by m_mutex? as well as unregisterRawMessageHandler() function.

Good catch, Sure I will put this in mutex as well.

Why I did it
Added the new APP_L2_NEXTHOP_GROUP_TABLE_NAME table in APPL_DB, along with support for registering and deregistering raw Netlink messages.
Direct handling of raw Netlink messages is required because libnl3 does not support Next Hop Group (NHG) message processing. Therefore, fdbsyncd needs to decode Kernel NHG messages to update the L2_NEXTHOP_GROUP_TABLE.
