The "-h" option of ssh-agent misses the option "O". 1) For the option "O", the following code appears during option parsing and modifies the restrict_websafe in ssh-agent.c:2055-2059 for version 9.1p1. if (strcmp(optarg, "no-restrict-websafe") == 0) restrict_websafe = 0; else fatal("Unknown -O option"); break; But it does not appear in the document provided by "-h". It may prevent users from using the relevant function.
This was fixed in 9fd24411
OpenSSH 9.3 has been released. Close resolved bugs
