2022-08-24vlib: allow longer version stringMatthew Smith1-2/+2
Type: improvement When trying to use a version string in a downstream build that appends a timestamp to the standard version string, compiling fails because the version string is too long for the version and version_required fields in vlib_plugin_registration_t. Increase the size of those arrays from 32 to 64 chars. Signed-off-by: Matthew Smith <mgsmith@netgate.com> Change-Id: I3632139e5ae7110aa4769359f380ad29522ad4ed
2022-07-06misc: pass NULL instead of 0 for pointer in variadic functionsAndreas Schultz2-12/+9
0 is not NULL (at least not in all cases), passing 0 into a variadic function in a place where the consumer reads it as pointer might leave parts of the pointer uninitilized and hence filled with random data. It seems that this used to work with gcc, but clang seems to treat the 0 in those places as a 32bit integer.

2022-05-13vlib: process startup config exec scripts line by lineDamjan Marion1-1/+13
This fixes long standing annoyance that CLIs with optional args cannot be executed from file, as they cannot distinguish between valid optional args and next line in the file. Multiline statements can be provided simply by using backslash before \n. Also comments are supported - everything after # is ignored up to the end of the line. Example: # multiline cli using backslash show version \ verbose # end of line comment packet-generator new { \ name x \ limit 5 \ # comment inside cmultiline cli \ size 128-128 \ interface local0 \ node null-node \ data { \ incrementing 30 \ } \ } Type: fix Change-Id: Ia6d588169bae14e6e3f18effe94820d05ace1dbf Signed-off-by: Damjan Marion <damarion@cisco.com>

2021-08-27vlib: vpp banner is outputted to non-interactive vppctl sessionSteven Luong1-0/+11
Running a batch file which contains many vppctl commands, occasionally, VPP may spit out the banner for some of the commands. This happens when VPP erroneously views the vppctl session as interactive. A simple way to recreate the problem is to run a batch script as followed while [ 1 ] do vppctl create loopback interface vppctl delete loopback interface intfc loop0 done We have two processes which may display the banner, unix_cli_new_session_process and unix_cli_process. Normally, unix_cli_process parses the input tokens and displays the banner after it negotiates the terminal type with the vppctl app. unix_cli_new_session_process only displays the banner just in case the client fails to negotiate terminal type. It runs on a timer and expires in 1 second to display the banner if by then the terminal type is still not yet negotiated. The problem is when the session is killed or exitted, VPP does not remove the element that was enqueued for cli_new_session_process. The index for the connection (cf) is recycled. The timer for the queue element continues to run. When the timer expires for the queue element, it finds the wrong new session due to index recycling. If the new session has not had negotiated the terminal type, the banner is printed erroneously to the new session from cli_new_session_process. The fix is to clean up the queue element to stop cli_new_session_process from processing the wrong connection when the session is killed.
