2020-11-10cnat: Fix invalid adj_indexNathan Skrzypczak2-10/+29
Type: fix When using sNAT in combination with cnat translations it might happen that the cnat_node_vip.c picks up a translation on a session that has an invalid lb index, thus resulting in a later crash in ip4-load-balance Change-Id: I82607086b2d672a9dcf26bfb82ad7f83e6474562 Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com>

Type: fix Allow for 65536 backends for a translation. - use u32 instead of u8 - filter out back_walk with more than FIB_PATH_LIST_POPULAR backends - we're still limited by u16 lb_n_buckets in src/vnet/dpo/load_balance.h Change-Id: Ib37b958e59b25ef5ef9f92b82008d626860faddd Signed-off-by: Nathan Skrzypczak <nathan.skrzypczak@gmail.com>

2020-09-27cnat: fix cnat_translation_cli_add_delDave Barach1-12/+24
Make the command scriptable, use unformat_line_input. "paths" never needed to be a pool, it's used as a vector. Pools *are* vectors so no harm but... use vec_add2(...) instead. Type: fix Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I65b42de77c3c17f532443319d8a5a15a0a930d66
