libceph: pass the message pointer instead of loading con->out_msg

2025-10-08T21:30:46Z

This pointer is in a register anyway, so let's use that instead of reloading from memory everywhere. [ idryomov: formatting ] Signed-off-by: Max Kellermann Reviewed-by: Viacheslav Dubeyko Signed-off-by: Ilya Dryomov

libceph: make ceph_con_get_out_msg() return the message pointer

2025-10-08T21:30:46Z

The caller in messenger_v1.c loads it anyway, so let's keep the pointer in the register instead of reloading it from memory. This eliminates a tiny bit of unnecessary overhead. Signed-off-by: Max Kellermann Reviewed-by: Viacheslav Dubeyko Signed-off-by: Ilya Dryomov

libceph: Use HMAC-SHA256 library instead of crypto_shash

Use the HMAC-SHA256 library functions instead of crypto_shash. This is simpler and faster. Signed-off-by: Eric Biggers Reviewed-by: Viacheslav Dubeyko Signed-off-by: Ilya Dryomov

ceph: Remove osd_client deadcode

2025-04-03T19:35:32Z

osd_req_op_extent_osd_data_pagelist() was added in 2013 as part of commit a4ce40a9a7c1 ("libceph: combine initializing and setting osd data") but never used. The last use of osd_req_op_cls_request_data_pagelist() was removed in 2017's commit ecd4a68a26a2 ("rbd: switch rbd_obj_method_sync() to ceph_osdc_call()") Remove them.

ceph: streamline request head structures in MDS client

2025-01-27T15:07:42Z

The existence of the ceph_mds_request_head_old structure in the MDS client code is no longer required due to improvements in handling different MDS request header versions. This patch removes the now redundant ceph_mds_request_head_old structure and replaces its usage with the flexible and extensible ceph_mds_request_head structure. Changes include: - Modification of find_legacy_request_head to directly cast the pointer to ceph_mds_request_head_legacy without going through the old structure. - Update sizeof calculations in create_request_message to use offsetofend for consistency and future-proofing, rather than referencing the old structure. - Use of the structured ceph_mds_request_head directly instead of the old one. Additionally, this consolidation normalizes the handling of request_head_version v1 to align with versions v2 and v3, leading to a more consistent and maintainable codebase. These changes simplify the codebase and reduce potential confusion stemming from the existence of an obsolete structure.
