Prevent erroneous "Login blocked after [negative number] attempts" errors
|

|

commit 91a76db66bb496ba4650ada38df31636297738cf

Prevent erroneous "Login blocked after [negative number] attempts" errors
|
||||
|
||||
For root, faillock appears to always* return an empty string (i.e. no table headers are present), yielding a zero-initialized pam_faillock_output_count and thus resulting in the calculation of a negative failed_login_counter value.
|
||||
|
||||
This can cause erroneous errors of the form "ERROR: Login blocked after [negative number] attempts" during sudo-ing and screen unlocking.
|
||||
|
||||
This commit modifies the initialization of failed_login_counter such that it cannot be negative and prevents the display of these incorrect warnings.
|
||||
|
||||
* Only rudimentary local tests were conducted
