From 2ea88716369ac9a7486a8cb309d6bf1239ea156c Mon Sep 17 00:00:00 2001 From: Ilya Dryomov Date: Sun, 23 Jan 2022 17:27:47 +0100 Subject: libceph: make recv path in secure mode work the same as send path The recv path of secure mode is intertwined with that of crc mode. While it's slightly more efficient that way (the ciphertext is read into the destination buffer and decrypted in place, thus avoiding two potentially heavy memory allocations for the bounce buffer and the corresponding sg array), it isn't really amenable to changes. Sacrifice that edge and align with the send path which always uses a full-sized bounce buffer (currently there is no other way -- if the kernel crypto API ever grows support for streaming (piecewise) en/decryption for GCM [1], we would be able to easily take advantage of that on both sides).
