The switch to memory_startswith() changed the logic to only look for a space or
NUL byte after the matched word, but matching the full size should also be
acceptable.
This changed the behavior of parsing of "AUTH\r\n", where m will be set to 4,
since even though the word will match, the check for it being followed by ' '
or NUL will make line_begins() return false.
Tested:
- Using netcat to connect to the private socket directly:
$ echo -ne '\0AUTH\r\n' | sudo nc -U /run/systemd/private
REJECTED EXTERNAL ANONYMOUS
- Running the Ignition blackbox test:
$ sudo sh -c 'PATH=$PWD/bin/amd64:$PATH ./tests.test'
PASS
