Allotment Routing Table
Hi,
Thanks for this great piece of SW.
One issue we found was that there is no API to delete/free the table.
We wrote the following C++ wrapper to do the deletion/free.
It first traverse the tree and collects all entries into a vector. Then it deletes each vector element from the table. Finally, it deletes the default entry and the root elements.
Note that mTable is a pointer to rtTable.
Two questions:
IpArtWrapper::~IpArtWrapper()
{
vector<routeEnt*> rEnts;
auto func = [](routeEnt* ent, void* p) {
auto pv = (vector<routeEnt*>*)p;
pv->push_back(ent);
};
rtArtWalkTable(mTable, mTable->root, 1, 1 << mTable->psi[0].sl, func, &rEnts);
for (auto ent : rEnts)
assert(mTable->deletep(mTable, ent->dest, ent->plen));
routeEnt* defRoute = mTable->root[1].ent;
if (defRoute) {
// delete default route manually, since rtArtWalkTable doesn't give it
u8 dst[16] = {0};
assert(mTable->deletep(mTable, dst, 0));
}
free(mTable->psi);
// mTable->pEnt is freed automatically when deleting routes
free(mTable->pDef);
free(mTable->pTbl);
free(mTable->pPcSt);
free(mTable->root + mTable->off);
free(mTable);
}
