p11sak: Fix parsing of slot number 0
|
|
|
|
Running command 'p11sak list-key aes --slot 0' may result in
|
|
'p11sak: Invalid argument '0' for option '-s/--slot''
|
|
|
|
This is because of the error checking after strtoul() within function
|
|
process_number_argument(). In case errno is not zero, it treats a
|
|
parsed value of zero as an error.
|
|
|
|
Under certain circumstances, errno is non-zero already before calling
|
|
strtoul(), and stays non-zero in case of strtoul() succeeds. This leads to
|
|
an incorrect error checking, and it is treated as error.
|
|
|
|
Initialize errno to zero before calling strtoul() to avoid such false error
|
|
detection.
