samples: pktgen: add helper functions for IP(v4/v6) CIDR parsing

2019-10-07T13:26:32Z

This commit adds CIDR parsing and IP validate helper function to parse single IP or range of IP with CIDR. (e.g. 198.18.0.0/15) Validating the address should be preceded prior to the parsing. Helpers will be used in prior to set target address in samples/pktgen. Signed-off-by: Daniel T. Lee Acked-by: Jesper Dangaard Brouer Signed-off-by: David S. Miller

samples: pktgen: fix proc_cmd command result check logic

2019-10-07T13:26:32Z

Currently, proc_cmd is used to dispatch command to 'pg_ctrl', 'pg_thread', 'pg_set'. proc_cmd is designed to check command result with grep the "Result:", but this might fail since this string is only shown in 'pg_thread' and 'pg_set'. This commit fixes this logic by grep-ing the "Result:" string only when the command is not for 'pg_ctrl'. For clarity of an execution flow, 'errexit' flag has been set. To cleanup pktgen on exit, trap has been added for EXIT signal. Signed-off-by: Daniel T. Lee Acked-by: Jesper Dangaard Brouer Signed-off-by: David S. Miller

samples: pktgen: add some helper functions for port parsing

2019-07-01T18:02:20Z

This commit adds port parsing and port validate helper function to parse single or range of port(s) from a given string. (e.g. 1234, 443-444) Helpers will be used in prior to set target port(s) in samples/pktgen. Signed-off-by: Daniel T. Lee Acked-by: Jesper Dangaard Brouer Signed-off-by: David S. Miller

pktgen: new pktgen helper functions for samples scripts

2015-05-23T03:59:16Z

Preparing for removing existing samples/pktgen/ scripts, and replacing these with easier to use samples. This commit provides two helper shell files, that can be "included" by shell source'ing. Namely "functions.sh" and "parameters.sh". The parameters.sh file support easy and consistant parameter parsing across the sample scripts. Usage example is printed on errors. The functions.sh file provides, three new shell functions for configuring the different components of pktgen: pg_ctrl(), pg_thread() and pg_set(). A slightly improved version of the old pgset() function is also provided for backwards compat. The new functions correspond to pktgens different components. * pg_ctrl() control "pgctrl" (/proc/net/pktgen/pgctrl) * pg_thread() control the kernel threads and binding to devices * pg_set() control setup of individual devices These changes are borrowed from: https://github.com/netoptimizer/network-testing/tree/master/pktgen Signed-off-by: Jesper Dangaard Brouer Signed-off-by: David S.
