Title
nvme: fix reconnection fail due to reserved tag allocation
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.

"lang": "en",
"value": "AV:N - The affected code is the NVMe-over-Fabrics host driver (nvme-tcp/nvme-rdma/nvme-fc), and the controller reset that opens the race window is triggered directly from remote peer input \u2014 `nvme_tcp_state_change()` fires error recovery on a peer FIN/RST, and the receive path calls `nvme_tcp_error_recovery()` on any malformed PDU. A remote or on-path attacker against the NVMe/TCP connection (port 4420) can drive the vulnerable path without local access.\nAC:L - The attacker controls the reset side of the race and can force error recovery/reconnect cycles arbitrarily many times (reconnect re-arms the keep-alive timer each round), while the keep-alive period is deterministic at kato/2, so the window can be hit by retry and by timing; the bug was also observed occurring spontaneously in production. Once won, the leaked reserved tag is permanent \u2014 no further conditions are needed.\nPR:N - No credentials on the victim host are required \u2014 the triggering events (TCP FIN/RST, malformed NVMe/TCP PDU, unresponsive target) are handled by `nvme_tcp_state_change()` and the recv path before or independent of any NVMe-level authentication, and NVMe/TCP deployments commonly run with no DH-HMAC-CHAP or TLS at all.\nUI:N - Exploitation requires no action from any user or administrator; an already-established NVMe-oF connection is a system configuration precondition, not victim interaction, and the keep-alive/reset machinery runs autonomously in kernel workqueues.\nS:U - The impact is confined to the kernel and the host\u0027s own storage stack \u2014 no security authority boundary such as a VM, IOMMU, or sandbox is crossed.\nC:N - The defect is a reserved-tag leak causing an ABBA allocation deadlock; no memory is read out of bounds, no freed object is accessed, and no kernel data is disclosed to the attacker.\nI:N - There is no memory corruption, out-of-bounds write, or control-flow primitive \u2014 the only consequence is that a blk-mq tag is never returned, so no attacker-influenced data modification is possible.\nA:H - The admin queue can never reconnect (\"failed to reconnect admin_q forever\"), because the admin tagset is not reallocated on reconnect and the connect command\u0027s reserved tag allocation fails with -EAGAIN indefinitely, producing a permanent loss of the NVMe-oF storage path plus eventual controller deletion (and a hung, unkillable teardown worker blocked on queue freeze) \u2014 total availability loss for storage that is frequently the system\u0027s root or primary data volume."

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."

In my case, the tag was hold by a keep alive request\nwaiting inside admin_q, as we quiesced admin_q while reset ctrl, so the\nrequest maked as idle and will not process before reset success. As\nfabric_q shares tagset with admin_q, while reconnect remote target, we\nneed a tag for connect command, but the only one reserved tag was held\nby keep alive command which waiting inside admin_q. As a result, we\nfailed to reconnect admin_q forever. In order to fix this issue, I\nthink we should keep two reserved tags for admin queue."

A remote or on-path attacker against the NVMe/TCP connection (port 4420) can drive the vulnerable path without local access.\nAC:L - The attacker controls the reset side of the race and can force error recovery/reconnect cycles arbitrarily many times (reconnect re-arms the keep-alive timer each round), while the keep-alive period is deterministic at kato/2, so the window can be hit by retry and by timing; the bug was also observed occurring spontaneously in production. Once won, the leaked reserved tag is permanent \u2014 no further conditions are needed.\nPR:N - No credentials on the victim host are required \u2014 the triggering events (TCP FIN/RST, malformed NVMe/TCP PDU, unresponsive target) are handled by `nvme_tcp_state_change()` and the recv path before or independent of any NVMe-level authentication, and NVMe/TCP deployments commonly run with no DH-HMAC-CHAP or TLS at all.\nUI:N - Exploitation requires no action from any user or administrator; an already-established NVMe-oF connection is a system configuration precondition, not victim interaction, and the keep-alive/reset machinery runs autonomously in kernel workqueues.\nS:U - The impact is confined to the kernel and the host\u0027s own storage stack \u2014 no security authority boundary such as a VM, IOMMU, or sandbox is crossed.\nC:N - The defect is a reserved-tag leak causing an ABBA allocation deadlock; no memory is read out of bounds, no freed object is accessed, and no kernel data is disclosed to the attacker.\nI:N - There is no memory corruption, out-of-bounds write, or control-flow primitive \u2014 the only consequence is that a blk-mq tag is never returned, so no attacker-influenced data modification is possible.\nA:H - The admin queue can never reconnect (\"failed to reconnect admin_q forever\"), because the admin tagset is not reallocated on reconnect and the connect command\u0027s reserved tag allocation fails with -EAGAIN indefinitely, producing a permanent loss of the NVMe-oF storage path plus eventual controller deletion (and a hung, unkillable teardown worker blocked on queue freeze) \u2014 total availability loss for storage that is frequently the system\u0027s root or primary data volume."
