nvmet-auth: fix nvmet_auth hash error handling

2024-07-08T17:28:16Z

If we fail to call nvme_auth_augmented_challenge, or fail to kmalloc for shash, we should free the memory allocation for challenge, so add err path out_free_challenge to fix the memory leak.

nvmet-fc: Remove __counted_by from nvmet_fc_tgt_queue.fod[]

2024-06-26T17:13:04Z

Work for __counted_by on generic pointers in structures (not just flexible array members) has started landing in Clang 19 (current tip of tree). During the development of this feature, a restriction was added to __counted_by to prevent the flexible array member's element type from including a flexible array member itself such as: struct foo { int count; char buf[]; }; struct bar { int count; struct foo data[] __counted_by(count); }; because the size of data cannot be calculated with the standard array size formula: sizeof(struct foo) * count This restriction was downgraded to a warning but due to CONFIG_WERROR, it can still break the build. The application of __counted_by on the fod member of 'struct nvmet_fc_tgt_queue' triggers this restriction, resulting in: drivers/nvme/target/fc.c:151:2: error: 'counted_by' should not be applied to an array with element of unknown size because 'struct nvmet_fc_fcp_iod' is a struct type with a flexible array member. This will be an error in a future compiler version [-Werror,-Wbounds-safety-counted-by-elt-type-unknown-size] 151 | struct nvmet_fc_fcp_iod fod[] __counted_by(sqsize); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 1 error generated. Remove this use of __counted_by to fix the warning/error. However, rather than remove it altogether, leave it commented, as it may be possible to support this in future compiler releases.

nvmet: add 'host_traddr' callback for debugfs

2024-06-24T19:53:43Z

We want to display the transport address of the connected host in debugfs, but this is a property of the transport. So add a callback 'host_traddr' to allow the transport drivers to fill in the data.
