Summary
In the Linux kernel, the following vulnerability has been resolved: nvme: fix reconnection fail due to reserved tag allocation We found a issue on production environment while using NVMe over RDMA, admin_q reconnect failed forever while remote target and network is ok. After dig into it, we found it may caused by a ABBA deadlock due to tag allocation. In my case, the tag was hold by a keep alive request waiting inside admin_q, as we quiesced admin_q while reset ctrl, so the request maked as idle and will not process before reset success. As fabric_q shares tagset with admin_q, while reconnect remote target, we need a tag for connect command, but the only one reserved tag was held by keep alive command which waiting inside admin_q. As a result, we failed to reconnect admin_q forever. In order to fix this issue, I think we should keep two reserved tags for admin queue.

Encontramos un problema en el entorno de producci\u00f3n al usar NVMe sobre RDMA, la reconexi\u00f3n de admin_q fall\u00f3 para siempre mientras el objetivo remoto y la red est\u00e1n bien. Despu\u00e9s de investigarlo, descubrimos que puede deberse a un punto muerto de ABBA debido a la asignaci\u00f3n de etiquetas. En mi caso, la etiqueta estaba retenida por una solicitud de mantenimiento en espera dentro de admin_q, ya que desactivamos admin_q mientras reiniciamos Ctrl, por lo que la solicitud se realiz\u00f3 como inactiva y no se procesar\u00e1 antes de que el reinicio se realice correctamente. Como fabric_q comparte el conjunto de etiquetas con admin_q, mientras reconectamos el objetivo remoto, necesitamos una etiqueta para el comando de conexi\u00f3n, pero la \u00fanica etiqueta reservada estaba mantenida por el comando Keep Alive que esperaba dentro de admin_q. Como resultado, no pudimos volver a conectar admin_q para siempre. Para solucionar este problema, creo que deber\u00edamos mantener dos etiquetas reservadas para la cola de administraci\u00f3n."
