nvmet-auth: select the intended CRYPTO_DH_RFC7919_GROUPS Commit 71ebe3842ebe ("nvmet-auth: Diffie-Hellman key exchange support") intends to select 'Support for RFC 7919 FFDHE group parameters' for using FFDHE groups for NVMe In-Band Authentication. It however selects CRYPTO_DH_GROUPS_RFC7919, instead of the intended CRYPTO_DH_RFC7919_GROUPS; notice the swapping of words here. Correct the select to the intended config option.

nvmet: implement basic In-Band Authentication Implement NVMe-oF In-Band authentication according to NVMe TPAR 8006. This patch adds three additional configfs entries 'dhchap_key', 'dhchap_ctrl_key', and 'dhchap_hash' to the 'host' configfs directory. The 'dhchap_key' and 'dhchap_ctrl_key' entries need to be in the ASCII format as specified in NVMe Base Specification v2.0 section 8.13.5.8 'Secret representation'. 'dhchap_hash' defaults to 'hmac(sha256)', and can be written to to switch to a different HMAC algorithm.

nvmet: fix ns enable/disable possible hang stable inclusion from stable-6.6.33 commit ca3b4293dccaa29e879df64809f08f8e6db69837 category: bugfix issue: #IB7W7N CVE: NA Signed-off-by: zhangshuqi <zhangshuqi3@huawei.com> --------------------------------------- [ Upstream commit f97914e35fd98b2b18fb8a092e0a0799f73afdfe ] When disabling an nvmet namespace, there is a period where the subsys->lock is released, as the ns disable waits for backend IO to complete, and the ns percpu ref to be properly killed. The original intent was to avoid taking the subsystem lock for a prolong period as other processes may need to acquire it (for example new incoming connections). However, it opens up a window where another process may come in and enable the ns, (re)intiailizing the ns percpu_ref, causing the disable sequence to hang. Solve this by taking the global nvmet_config_sem over the entire configfs enable/disable sequence.

Neither the transfer length nor halen/dhlen is validated. A malicious or non-conformant host can report a tl smaller than the negotiate structure, or a halen/dhlen larger than the array (both are u8, up to 255), making the loops read past the end of the allocated buffer (heap out-of-bounds read). The sibling nvmet_auth_reply() already validates tl against the structure size; the negotiate path did not. Pass tl into nvmet_auth_negotiate(), reject a tl that does not cover the negotiate data plus one full protocol descriptor, and reject halen/dhlen larger than NVME_AUTH_DHCHAP_MAX_DH_IDS.

However it's quite possible that during the window between quiescing and destroying of the admin/IO queue, some admin/IO request might sneak in and if that happens then we could potentially encounter a hung task because shutdown operation can't forward progress until any pending I/O is flushed off. This commit helps ensure that before destroying the admin/IO queue, we unquiesce the admin/IO queue so that any outstanding requests, which are added after the admin/IO queue is quiesced, are now flushed to its completion.

nvmet: fix NULL pointer dereference in nvmet_execute_identify_ns_zns() stable inclusion from stable-v6.6.157 commit ff28a93a895912010a7827a0e1445ebe8be53b4d category: bugfix issue: #1495 CVE: CVE-2026-90228 Signed-off-by: 姜小林 <jiangxiaolin11@h-partners.com> Co-Authored-By: Agent ------------------------------- nvmet: fix NULL pointer dereference in nvmet_execute_identify_ns_zns() [ Upstream commit f594863967d87b7fcbff6e724d51135fd701a13d ] When a host issues an Identify command with CNS 05h (I/O Command Set specific Identify Namespace) and CSI 02h (ZNS) targeting a file-backed namespace, nvmet_execute_identify_ns_zns() calls bdev_is_zoned() on req->ns->bdev. A file-backed namespace has no block device, so req->ns->bdev is NULL and bdev_is_zoned() dereferences it, oopsing. The I/O command set is selected by the host-supplied CSI field and the command is routed here whenever CONFIG_BLK_DEV_ZONED is enabled, independent of the namespace backing type, so any file-backed namespace is exposed. Reject the command with Invalid Field when the namespace is not backed by a block device.
