curl --local-port does not try last port in range #3251
(Mentioned in passing in #3248 but now raising as a separate issue.)
I did this
freia013:~/work/curl $ src/curl --local-port 1023-1024 localhost curl: (45) bind failed with errno 13: Permission denied freia013:~/work/curl $ src/curl --local-port 1024 localhost curl: (7) Failed to connect to localhost port 80: Connection refused freia013:~/work/curl $ src/curl --local-port 1023-1025 localhost curl: (7) Failed to connect to localhost port 80: Connection refused
I expected the following
With "1023-1024", curl should try to use port 1024 when 1023 fails, but it only tries 1023 then gives up. If I increase the range to "1023-1025" then it does use 1024. This can be seen in greater detail with additional -v or -libcurl.
localportrange needs to be incremented by one when subtracting last from first.
