This is a followup to
v1: https://lists.gnu.org/archive/html/qemu-devel/2017-08/msg00781.html
v2: https://lists.gnu.org/archive/html/qemu-devel/2017-08/msg06464.html
v3: https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg02923.html
This collection of patches first improves the performance of the
crypto block driver and then does various cleanups to improve ongoing
maint work.
Changed in v4:
- Drop intermediate patch that replaced '512' with a constant (Max)
- Use MIN() macro where needed (Max)
- Fix bounce buffer size at 1MB instead of varying per sector size (Max)
- Convert missing qcrypto_block_encrypt call to sectors in qcow.c (Max)
Changed in v3:
- Support passthrough of BDRV_REQ_FUA (Eric)
- Fix potential truncation of payload offset values (Eric)
- Use encryption scheme sector size instead of BDRV_SECTOR_SIZE (Kevin)
- Use QEMU_IS_ALIGNED where appropriate (Eric)
- Remove unused 'sector_num' variable (Eric)
- Fix whitespace alignment (Eric)
- Fix math error in qcow conversion (Eric)
Daniel P. Berrange (6):
block: use 1 MB bounce buffers for crypto instead of 16KB
crypto: expose encryption sector size in APIs
block: fix data type casting for crypto payload offset
block: convert crypto driver to bdrv_co_preadv|pwritev
block: convert qcrypto_block_encrypt|decrypt to take bytes offset
block: support passthrough of BDRV_REQ_FUA in crypto driver
