2017-02-22VPP-635: CLI Memory leak with invalid parameterBilly McFall36-572/+1472
In the CLI parsing, below is a common pattern: /* Get a line of input. */ if (!unformat_user (input, unformat_line_input, line_input)) return 0; while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT) { if (unformat (line_input, "x")) x = 1; : else return clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); } unformat_free (line_input); The 'else' returns if an unknown string is encountered. There a memory leak because the 'unformat_free(line_input)' is not called. There is a large number of instances of this pattern. Replaced the previous pattern with: /* Get a line of input. */ if (!unformat_user (input, unformat_line_input, line_input)) return 0; while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT) { if (unformat (line_input, "x")) x = 1; : else { error = clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); goto done: } } /* ...Remaining code... */ done: unformat_free (line_input); return error; } In multiple files, 'unformat_free (line_input);' was never called, so there was a memory leak whether an invalid string was entered or not. Also, there were multiple instance where: error = clib_error_return (0, "unknown input `%U'", format_unformat_error, line_input); used 'input' as the last parameter instead of 'line_input'. The result is that output did not contain the substring in error, instead just an empty string. Fixed all of those as well. There are a lot of file, and very mind numbing work, so tried to keep it to a pattern to avoid mistakes.

2017-02-22jvpp: remove unnecessary msg_id_base cachingMarek Gradzki11-178/+90
Jvpp code uses CRCs to obtain msg IDs. Checking api_main_t.msg_index_by_name_and_crc is enough to detect API mismatch. Calling vl_client_get_first_plugin_msg_id is not needed. Also fixes VPP-627. Change-Id: Ie3085dfa458795fa11f17615ac94e76197a1c8cd Signed-off-by: Marek Gradzki <mgradzki@cisco.com>

DHCP additions: 1) DHCPv4 will only relay a message back to the client, if the Option82 information is present. So make this the default. 2) It is no longer possible to select via the API to "insert circuit ID" - since this is now default 3) Remove the version 2 API since it's now the same as version 1. 4) Adding the VSS option is now conditional only on the presence of VSS config (not the 'insert' option in the set API) 5) DHCP proxy dump via API Change-Id: Ia7271ba8c1d4dbf34a02c401d268ccfbb1b74f17 Signed-off-by: Neale Ranns <nranns@cisco.com>

- IKE_SA_INIT and IKE_AUTH initial exchanges - Delete IKA SA - Rekey and delete Child SA - Child SAs lifetime policy To set up one VPP instance as the initiator use the following CLI commands (or API equivalents): ikev2 profile set <id> responder <interface> <addr> ikev2 profile set <id> ike-crypto-alg <crypto alg> <key size> ike-integ-alg <integ alg> ike-dh <dh type> ikev2 profile set <id> esp-crypto-alg <crypto alg> <key size> esp-integ-alg <integ alg> esp-dh <dh type> ikev2 profile set <id> sa-lifetime <seconds> <jitter> <handover> <max bytes> and finally ikev2 initiate sa-init <profile id> to initiate the IKE_SA_INIT exchange Child SA re-keying process: 1. Child SA expires 2. A new Child SA is created using the Child SA rekey exchange 3. For a set time both SAs are alive 4.

2017-02-16tw_timer_expire_timers() - add a maximum to the number of expiration per callGabriel Ganne2-3/+10
The idea is to prevent a huge processing burst if, say, the network goes down 10' for some reason, and so that we don't need to expire 1M timer sessions on the first call. The maximum is not an exact value, but a value after which the expiration process is postponed until the next call. That way, we don't have to process the same tick twice, nor to unlink timers once at a time when processing a tick. The fact that a timer slot could contain many entries should be dealt with by changing the number of ticks per second.

2017-02-16VPP-638: 'set interface ipsec key garbage' causes infinite loopBilly McFall1-0/+5
In the CLI parsing of 'set interface ipsec key garbage', the token 'garbage' enters the processing code for the <key>. This enters unformat_hex_string(..) which looks through the input for 0-9,a-f and drops out if a non-hex digit is encountered. The problem is that it returns 1, indicating that input has been processed, but in this case, no characters have been removed from the input string. This causes the calling function to go to the top of the loop and process the next token, which is now the same token and gets stuck in an infinite loop. Updated unformat_hex_string(..) to return 0 if no characters were processed. This funcitons is used in multiple CLI Commands, but most have token that preceeds the hex string. Since the token is stripped, the CLI command is able to avoid an infinte loop. Change-Id: Ib54f04f23c4d3563ec57a2450982d3648cedec0e Signed-off-by: Billy McFall <bmcfall@redhat.com>

Add doxygen documentation for pcap tx trace CLI command. In the process of adding the documentation, made the following changes to the way the command worked: * If there is an error with any of the attributes, the whole command fails. The existing behavior was to apply attribute by attribute, then bail if there was an issue, with partial apply. * Move the 'on' processing to the end. The existing behavior was to process the 'on' as it was encountered on the commandline. That meant that any attributes after the 'on' in the commandline were saved and displayed, but not really being used in the packet trace. * Enhanced the 'status' to show all the configured attributes. NOTE: The packet capture has some weird behavior with regards to how many packets are written to file and if the file is appended or overwritten. VPP-634 written to document the issue.

Fruthermore, rather than forcing every API user to hoop-jump to establish these context values, simply provide them in their DETAILS reply messages.
