2017-10-30Add the bihash_vec8_8 variantDave Barach1-3/+10
This is an all-purpose octet-vector memory hash, intended as a thread-safe replacement for hash_create_mem / hash_create_string. All u8 * key vectors are memorized by the hash table. Change-Id: I22944daea8fda07dde8ba118a6529a6d382491f9 Signed-off-by: Dave Barach <dave@barachs.net>

2017-09-09move unix_file_* code to vppinfraDamjan Marion1-0/+1
This will allow us to use this code in client libraries without vlib. Change-Id: I8557b752496841ba588aa36b6082cbe2cd1867fe Signed-off-by: Damjan Marion <damarion@cisco.com>
2017-09-01Add fixed-size, preallocated pool supportDave Barach1-11/+15
Simply call pool_init_fixed(...) before using the pool. Note that fixed, preallocated pools live in individually-mmap'ed address segments, except for the free element bitmap. A large fixed pool can exceed 4gb. Fix tcp buffer allocator leak, remove broken assert Change-Id: I4421082e12a77c41c6e20f7747f3150dcd01fc26 Signed-off-by: Dave Barach <dave@barachs.net>
2017-07-19Add a bihash prefetchable bucket-level cacheDave Barach1-0/+2
According to Maciek, the easiest way to leverage the csit "performance trend" job is to actually merge the patch once verified. Manual testing indicates that the patch improves l2 path performance. Other use-cases are TBD. It's possible that we'll need to back out the patch depending on what happens.

2017-07-01Refactor API message handling codeKlement Sekera1-0/+1
This is preparation for new C API. Moving common stuff to separate headers reduces dependency issues. Change-Id: Ie7adb23398de72448e5eba6c1c1da4e1bc678725 Signed-off-by: Klement Sekera <ksekera@cisco.com>

2017-05-10Add crc32c inline function, allows compilation on 32-bit systemsDamjan Marion1-0/+1
32-bit code still can use crc32c instructions, but it operates on 32 registers Change-Id: I9bb6b0b59635d6ea6a753584676ebcf59c8f6584 Signed-off-by: Damjan Marion <damarion@cisco.com>

2017-01-27IP Multicast FIB (mfib)Neale Ranns1-1/+1
- IPv[46] mfib tables with support for (*,G/m), (*,G) and (S,G) exact and longest prefix match - Replication represented via a new replicate DPO. - RPF configuration and data-plane checking - data-plane signals sent to listening control planes. The functions of multicast forwarding entries differ from their unicast conterparts, so we introduce a new mfib_table_t and mfib_entry_t objects. However, we re-use the fib_path_list to resolve and build the entry's output list. the fib_path_list provides the service to construct a replicate DPO for multicast. 'make tests' is added to with two new suites; TEST=mfib, this is invocation of the CLI command 'test mfib' which deals with many path add/remove, flag set/unset scenarios, TEST=ip-mcast, data-plane forwarding tests. Updated applications to use the new MIFB functions; - IPv6 NS/RA. - DHCPv6 unit tests for these are undated accordingly.
