2019-12-04ip: populate ip_reassembly_get_reply correctlyMatthew Smith1-3/+4
Type: fix Fixes: de34c35fc The API handler for requests to retrieve IP reassembly settings was modified to support shallow virtual reassembly. It retrieves settings into local variables now instead of directly into the reply message. The fields in the reply message were not being populated using those variables. So the reply message was being sent with all 0's, except in the is_ip6 field. Also, the max_reassembly length field in the reply message was not being populated.

2019-11-26fib: Table ReplaceNeale Ranns2-131/+126
Type: feature from the API doc, a table replace is: " The use-case is that, for some unspecified reason, the control plane has a very different set of entries it wants in the table than VPP currently has. The CP would thus like to 'replace' VPP's current table only by specifying what the new set of entries shall be, i.e. it is not going to delete anything that already eixts. the CP delcartes the start of this procedure with this begin_replace API Call, and when it has populated all the entries it wants, it calls the below end_replace API. From this point on it is of coursce free to add and delete entries as usual. The underlying mechanism by which VPP implements this replace is purposefully left unspecified. " In the FIB, the algorithm is implemented using mark and sweep. Algorithm goes: 1) replace_begin: this marks all the entries in that table as 'stale' 2) download all the entries that should be in this table - this clears the stale flag on those entries 3) signal the table converged: ip_table_replace_end - this removes all entries that are still stale this procedure can be used when an agent first connects to VPP, as an alternative to dump and diff state reconciliation.

2019-11-10dhcp: ipv6 prefix delegation improvementsDave Barach1-1/+17
Autoconfigure router advertisements for delegated prefixes. Clean up a longstanding issue. If vpp receives a dhcpv6 renew reply, do NOT reset per-delegated-prefix timers. That prevented vpp from sending a solicit to renew the delegation on time. That, in turn caused the RA code to send advertisements with valid_time = preferred_time = 0. That causes almost any downstream client to throw away its delegated address. Miscellaneous changes o src/vnet/ip/ip6_neighbor.c - always memset elements allocated from pools to zero. DGMS. o Remove debug spew from the ipv6 connection-tracker plugin Type: feature Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I428feccdc47efdc413898600e0d62916928a6eb7

2019-10-29ip: refactor ip4_mtrie to atomically unset leavesjaszha031-4/+6
ip4_mtrie set leaves atomically in set_leaf () and set_root_leaf () but deleted leaves using regular stores in unset_leaf () and unset_root_leaf (). Changed leaf deletion to update mtrie using atomic store-release. Slight performance improvement was observed in benchmarking on Qualcomm and Xeon machines. Benchmarking involved running 'ip route add' and 'ip route del' on vpp instances. Below are the routes/second for adding and deleting 100k routes before and after the store-release changes: Xeon Add Routes Before: 1.140e6, 1.139e6, 1.148e6, 1.158e6, 1.155e6 Xeon Add Routes After: 1.167e6, 1.170e6, 1.174e6, 1.173e6, 1.169e6 Xeon Del Routes Before: 7.287e7, 8.089e7, 6.048e7, 7.171e7, 7.821e7 Xeon Del Routes After: 8.729e7, 7.353e7, 7.856e7, 8.209e7, 7.787e7 Qualcomm Add Routes Before: 3.709e5, 3.954e5, 3.739e5, 3.759e5, 3.671e5 Qualcomm Add Routes After: 3.879e5, 3.967e5, 3.936e5, 3.764e5, 3.817e5 Qualcomm Del Routes Before: 1.286e7, 1.379e7, 1.353e7, 1.230e7, 1.331e7 Qualcomm Del Routes After: 1.411e7, 1.355e7, 1.373e7, 1.394e7, 1.314e7 Type: refactor Change-Id: If3acd25a2fb87addd0eb13d82d3c8f46579e8060 Signed-off-by: Jason Zhang <jason.zhang2@arm.com> Reviewed-by: Lijian Zhang <Lijian.Zhang@arm.com> Reviewed-by: Ruifeng Wang <ruifeng.wang@arm.com>
