This patch replaces the seqniv generator with seqiv when the underlying algorithm understands the new calling convention. This not only makes more sense as now seqiv is solely responsible for IV generation rather than also determining how the IV is going to be used, it also allows for optimisations in the underlying implementation. For example, the space for the IV could be used to add padding for authentication. This patch also removes the unnecessary copying of IV to dst during seqiv decryption as the IV is part of the AD and not cipher text. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

This patch fixes a bug where we were incorrectly including the IV in the AD during encryption. The IV must remain in the plain text for it to be encrypted. During decryption there is no need to copy the IV to dst because it's now part of the AD. This patch removes an unncessary check on authsize which would be performed by the underlying decrypt call. Finally this patch makes use of the type-safe init/exit functions. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

This patch adds a type-safe function for freeing AEAD instances to struct aead_instance. This replaces the existing free function in struct crypto_template which does not know the type of the instance that it's freeing. Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

Currently the task of freeing an instance is given to the crypto template. However, it has no type information on the instance so we have to resort to checking type information at runtime. This patch introduces a free function to crypto_type that will be used to free an instance. This can then be used to free an instance in a type-safe manner.

This patch fixes a host of reentrancy bugs in the nx driver. The following algorithms are affected: * CCM * GCM * CTR * XCBC * SHA256 * SHA512 The crypto API allows a single transform to be used by multiple threads simultaneously. For example, IPsec will use a single tfm to process packets for a given SA. As packets may arrive on multiple CPUs that tfm must be reentrant. The nx driver does try to deal with this by using a spin lock. Unfortunately only the basic AES/CBC/ECB algorithms do this in the correct way. The symptom of these bugs may range from the generation of incorrect output to memory corruption. Cc: stable@vger.kernel.org Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

The current documention mentions explicitly that EINVAL should be returned if the device is not available, but nx842_OF_upd_status() always returns 0. However, nx842_probe() specifically checks for non-ENODEV returns from nx842_of_upd() (which in turn calls nx842_OF_upd_status()) and emits an extra error in that case.

Commit 835a6a2f ("Bluetooth: Stop sabotaging list poisoning") thought that the code was sabotaging the list poisoning when NULL'ing out the list pointers and removed it. But what was going on was that the bluetooth code was using NULL pointers for the list as a way to mark it empty, and that commit just broke it (and replaced the test with NULL with a "list_empty()" test on a uninitialized list instead, breaking things even further). So fix it all up to use the regular and real list_empty() handling (which does not use NULL, but a pointer to itself), also making sure to initialize the list properly (the previous NULL case was initialized implicitly by the session being allocated with kzalloc()) This is a combination of patches by Marcel Holtmann and Tedd Ho-Jeong An.

Pull SCSI target updates from Nicholas Bellinger: "It's been a busy development cycle for target-core in a number of different areas. The fabric API usage for se_node_acl allocation is now within target-core code, dropping the external API callers for all fabric drivers tree-wide. There is a new conversion to RCU hlists for se_node_acl and se_portal_group LUN mappings, that turns fast-past LUN lookup into a completely lockless code-path. It also removes the original hard-coded limitation of 256 LUNs per fabric endpoint. The configfs attributes for backends can now be shared between core and driver code, allowing existing drivers to use common code while still allowing flexibility for new backend provided attributes. The highlights include: - Merge sbc_verify_dif_* into common code (sagi) - Remove iscsi-target support for obsolete IFMarker/OFMarker (Christophe Vu-Brugier) - Add bidi support in target/user backend (ilias + vangelis + agover) - Move se_node_acl allocation into target-core code (hch) - Add crc_t10dif_update common helper (akinobu + mkp) - Handle target-core odd SGL mapping for data transfer memory (akinobu) - Move transport ID handling into target-core (hch) - Move task tag into struct se_cmd + support 64-bit tags (bart) - Convert se_node_acl->device_list[] to RCU hlist (nab + hch + paulmck) - Convert se_portal_group->tpg_lun_list[] to RCU hlist (nab + hch + paulmck) - Simplify target backend driver registration (hch) - Consolidate + simplify target backend attribute implementations (hch + nab) - Subsume se_port + t10_alua_tg_pt_gp_member into se_lun (hch) - Drop lun_sep_lock for se_lun->lun_se_dev RCU usage (hch + nab) - Drop unnecessary core_tpg_register TFO parameter (nab) - Use 64-bit LUNs tree-wide (hannes) - Drop left-over TARGET_MAX_LUNS_PER_TRANSPORT limit (hannes)" * 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending: (76 commits) target: Bump core version to v5.0 target: remove target_core_configfs.h target: remove unused TARGET_CORE_CONFIG_ROOT define target: consolidate version defines target: implement WRITE_SAME with UNMAP bit using ->execute_unmap target: simplify UNMAP handling target: replace se_cmd->execute_rw with a protocol_data field target/user: Fix inconsistent kmap_atomic/kunmap_atomic target: Send UA when changing LUN inventory target: Send UA upon LUN RESET tmr completion target: Send UA on ALUA target port group change target: Convert se_lun->lun_deve_lock to normal spinlock target: use 'se_dev_entry' when allocating UAs target: Remove 'ua_nacl' pointer from se_ua structure target_core_alua: Correct UA handling when switching states xen-scsiback: Fix compile warning for 64-bit LUN target: Remove TARGET_MAX_LUNS_PER_TRANSPORT target: use 64-bit LUNs target: Drop duplicate + unused se_dev_check_wce target: Drop unnecessary core_tpg_register TFO parameter ...
