ChangeLog (10505B)

 Logswan 2.1.13 (2022-07-28)
 
 - Remove useless backslashes in usage()
 - Add entries with IPv6 remote hosts to exercise the IPv6 code paths
 - Add an invalid.log log file with invalid lines, for testing purposes
 - Add a few more test cases in CMakeLists.txt
 - Also generate data for IPv6 addresses in the MMDB test database
 - Regenerate the example MMDB database and JSON example output
 
 
 
 Logswan 2.1.12 (2021-12-02)
 
 - Fix a use-after-free (read) triggered by strcmp(3) calls.
 
   The parse_request() function didn't zero out the parsed_request struct
   between each call. Since the parsing loop was switched to using getline(3)
   instead of a fixed size buffer to process log lines, it could reference
   already freed memory in certain cases.
 
   Thanks to Brian Carpenter (@geeknik) for finding and reporting the issue.
 
 
 
 Logswan 2.1.11 (2021-11-16)

 - Switch to using getline(3) instead of fgets(3)
 - Call hll_init() after doing getopt() processing
 
 
 
 Logswan 2.1.10 (2021-02-15)

   crash on program exit on OpenBSD when running without the GeoIP
   option enabled.
