When there is no 21 enough available memory, the respective strategy will be 22 enabled and the variable is automatically set to 2, otherwise 23 the strategy is disabled and the variable is set to 1. 24 25 backup_only - BOOLEAN 26 - 0 - disabled (default) 27 - not 0 - enabled 28 29 If set, disable the director function while the server is 30 in backup mode to avoid packet loops for DR/TUN methods. 31 32 conn_lfactor - INTEGER 33 Possible values: -8 (larger table) .. 8 (smaller table) 34 35 Default: -4 36 37 Controls the sizing of the connection hash table based on the 38 load factor (number of connections per table buckets): 39 40 2^conn_lfactor = nodes / buckets 41 42 As result, the table grows if load increases and shrinks when 43 load decreases in the range of 2^8 - 2^conn_tab_bits (module 44 parameter). 45 The value is a shift count where negative values select 46 buckets = (connection hash nodes << -value) while positive 47 values select buckets = (connection hash nodes >> value). The 48 negative values reduce the collisions and reduce the time for 49 lookups but increase the table size. Positive values will 50 tolerate load above 100% when using smaller table is 51 preferred with the cost of more collisions. If using NAT 52 connections consider decreasing the value with one because 53 they add two nodes in the hash table. 54 55 Example: 56 -4: grow if load goes above 6% (buckets = nodes * 16) 57 2: grow if load goes above 400% (buckets = nodes / 4) 58 59 conn_max - INTEGER 60 Limit for number of connections, per netns. 61 62 Controls the soft and hard limit for number of connections. 63 Initially, the platform specific limit is assigned for init_net. 64 The value can be changed and later the soft limit propagated 65 to other networking namespaces. 66 67 Privileged admin can change both limits up to the value of the 68 platform limit while the unprivileged admin can change only the 69 soft limit up to the value of the hard limit. 70 71 For setups using conntrack=1 (CONFIG_IP_VS_NFCT for 72 Netfilter connection tracking) the connections can be 73 limited also by nf_conntrack_max. 74 75 soft limit hard limit > 76 ===================================================== 77 init_net: 78 create netns platform platform 79 priv admin 0 .. platform 0 .. platform 80 ===================================================== 81 new netns: 82 create netns init_net:soft init_net:soft 83 priv admin 0 .. platform 0 .. platform 84 unpriv admin 0 .. hard N/A 85 86 Limits per platform: 87 1,073,741,824 (2^30 for 64-bit) 88 16,777,216 (2^24 for 32-bit) 89 90 Possible values: 0 .. platform limit 91 92 Default: platform limit 93 -- 0-DAY CI Kernel Test Service https://github.com/intel/lkp-tests/wiki
