Hi, In my current linux 3.2.71 stable version , I have created a network namespace and when I listed sysctl variables in following directory " /proc/sys/net/core/" am able to see net.core.xfrm* variables only, i.e only CONFIG_SYSCTL related variables, even though I have enabled CONFIG_NET as well as CONFIG_NET_NS I am not able to see any sysctl variables related to ne.core(rmem_max, wmem_max, rmem_default and wmem_default). # ip netns exec gmk1 ls -l /proc/sys/net/core/ total 0 -rw-r--r-- 1 root root 0 Jul 25 03:01 somaxconn -rw-r--r-- 1 root root 0 Jul 25 03:01 xfrm_acq_expires -rw-r--r-- 1 root root 0 Jul 25 03:01 xfrm_aevent_etime -rw-r--r-- 1 root root 0 Jul 25 03:01 xfrm_aevent_rseqth -rw-r--r-- 1 root root 0 Jul 25 03:01 xfrm_larval_drop Where as in my older kernel version, it will show all sysctl variables. # ls -l /proc/sys/net/core/ total 0 -rw-r--r-- 1 root root 0 Jul 20 05:40 busy_poll -rw-r--r-- 1 root root 0 Jul 20 05:40 busy_read -rw-r--r-- 1 root root 0 Jul 20 05:40 default_qdisc -rw-r--r-- 1 root root 0 Jul 20 05:40 dev_weight -rw-r--r-- 1 root root 0 Jul 20 05:40 flow_limit_cpu_bitmap -rw-r--r-- 1 root root 0 Jul 20 05:40 flow_limit_table_len -rw-r--r-- 1 root root 0 Jul 20 05:40 message_burst -rw-r--r-- 1 root root 0 Jul 20 05:40 message_cost -rw-r--r-- 1 root root 0 Jul 20 05:40 netdev_budget -rw-r--r-- 1 root root 0 Jul 20 05:40 netdev_max_backlog -rw-r--r-- 1 root root 0 Jul 20 05:40 netdev_tstamp_prequeue -rw-r--r-- 1 root root 0 Jul 20 05:40 optmem_max -rw-r--r-- 1 root root 0 Jul 20 05:40 rmem_default -rw-r--r-- 1 root root 0 Jul 20 05:40 rmem_max -rw-r--r-- 1 root root 0 Jul 20 05:40 rps_sock_flow_entries -rw-r--r-- 1 root root 0 Jul 20 05:40 somaxconn -rw-r--r-- 1 root root 0 Jul 20 05:40 warnings -rw-r--r-- 1 root root 0 Jul 20 05:40 wmem_default -rw-r--r-- 1 root root 0 Jul 20 05:40 wmem_max -rw-r--r-- 1 root root 0 Jul 20 05:40 xfrm_acq_expires -rw-r--r-- 1 root root 0 Jul 20 05:40 xfrm_aevent_etime -rw-r--r-- 1 root root 0 Jul 20 05:40 xfrm_aevent_rseqth -rw-r--r-- 1 root root 0 Jul 20 05:40 xfrm_larval_drop Please furnish me how I can avoid such things.
