I'm not sure if this is actually to restrictive, because it means applications like Samba won't be able to use io-uring at all. As even if current_cred() and ctx->creds describe the same set of uid,gids the !=3D won't ever match again and makes the whole ring unuseable. I'm not sure about what the best short term solution could be... 1. May just doing the check for path based operations? and fail individual requests with EPERM. 2. Or force REQ_F_FORCE_ASYNC for path based operations, so that they're always executed from within the workqueue with were ctx->creds is active. 3. Or (as proposed earlier) do the override_creds/revert_creds dance (and similar for mm) if needed. To summaries the problem again: For path based operations like: - IORING_OP_CONNECT (maybe also - IORING_OP_ACCEPT???) - IORING_OP_SEND*, IORING_OP_RECV* on DGRAM sockets - IORING_OP_OPENAT, IORING_OP_STATX, IORING_OP_OPENAT2 it's important under which current_cred they are called. Are IORING_OP_MADVISE, IORING_OP_FADVISE and IORING_OP_FALLOCATE are only bound to the credentials of the passed fd they operate on? The current assumption is that the io_uring_setup() syscall captures the current_cred() to ctx->cred and all operations on the ring are executed under the context of ctx->cred. Therefore all helper threads do the override_creds/revert_creds dance. But the possible non-blocking line execution of operations in the io_uring_enter() syscall doesn't do the override_creds/revert_creds dance and execute the operations under current_cred(). This means it's random depending on filled cached under what credentials an operation is executed. In order to prevent security problems the current patch is enough, but as outlined above it will make io-uring complete unuseable for applications using any syscall that changes current_cred(). Change 1. would be a little bit better, but still not really useful. I'd actually prefer solution 3. as it's still possible to make use of non-blocking operations, while the security is the same as solution 2. metze --08ifXq7B35qYgABXunm0mbeROcydFK5PL-- --r6J6mLjvdqw1TxoqnmSwtjwf1dVJWqzd0 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEfFbGo3YXpfgryIw9DbX1YShpvVYFAl4qyQoACgkQDbX1YShp vVZeEA/8CBPEJYiu4wd9YbU8+R8JLXL1ykRZH1obAAIwC8B0efnC5GRbeG6qcMtb YqSxX3RzlkK9ev2G8WVDrRCqEWGY9W0f+8czswJObsRUdPc+SWVJEGOSKnKYvGRb LxFGgQGckTsWosvbcekn6UemtQzR/Ynd7Z/oByCAEcgz10oJfNXM0sZAQ4v5MDFi zmKF8rdEBdvCWx5pyg9syilYjOPDkBfFM9XzQEydhQMh8RcSqoZ8KZQ/Mvdtk/9/ uad4X6gXLH0hLvSlmiRd9RMOgO6YvqaVtzCFMNNLJyY8PkUu0YjlZWdhnqGrHidK zsADq7Cib2v0LeDEGiGKzy9MA/yIGInb0vX9F+Hl5lwaO361Kfiy5lrnjC9M6gnR mZCF2DY1aZrVeki1wwix8xTCBX9My4ECZE6PXPb/uySsAw3ss+7k4tGojAqLXqn6 Ft5FCr+hSG+nsYoCvadY41pDlGGZ1CoMXO6WBxRf31SS9jtgWZRNnl56kPL95BH0 k+qJom2DhmuQbSL+aV/Ik8ty2VvhvOLG3D9v9XjMwVLYMqI9usg86Q1n69z/JD+/ X1qzHo8VX0GHpPaztp6yQ1zrPVQdFedqIxI5P7N+61ltxwWjMpL0p7KXYxHvc52H +MwiD2OOQhjdsc7IG0hBKgpn2Go3ME9LH6gdszA82j0+DayotoE= =2eA/ -----END PGP SIGNATURE----- --r6J6mLjvdqw1TxoqnmSwtjwf1dVJWqzd0--
