Triggered by https://bugzilla.samba.org/show_bug.cgi?id=13128 I think this module should go. Once Linux aio will do what Samba needs, this might be worth another look. What we should instead do soon is support Linux preadv2 and the RWF_NOWAIT flag to avoid the thread context switch whenever possible.

Release Announcements
|
|
=====================
|
|
|
|
This is the first preview release of Samba 4.8. This is *not*
|
|
intended for production environments and is designed for testing
|
|
purposes only. Please report any defects via the Samba bug reporting
|
|
system at https://bugzilla.samba.org/.
|
|
|
|
Samba 4.8 will be the next version of the Samba suite.
|
|

|
UPGRADING
|
|
=========
|
|
|
|
|
|
NEW FEATURES/CHANGES
|
|
====================
|
|
|
|
Using x86_64 Accelerated AES Crypto Instructions
|
|
================================================
|
|
|
|
Samba on x86_64 can now be configured to use the Intel accelerated AES
|
|
instruction set, which has the potential to make SMB3 signing and
|
|
encryption much faster on client and server. To enable this, configure
|
|
Samba using the new option --accel-aes=intelaesni.
|
|
|
|
This is a temporary solution that is being included to allow users
|
|
to enjoy the benefits of Intel accelerated AES on the x86_64 platform,
|
|
but the longer-term solution will be to move Samba to a fully supported
|
|
external crypto library.
|
|
|
|
The third_party/aesni-intel code will be removed from Samba as soon as
|
|
external crypto library performance reaches parity.
|
|
|
|
The default is to build without setting --accel-aes, which uses the
|
|
existing Samba software AES implementation.
|
|
|
|
smb.conf changes
|
|
================
|
|
|
|
Parameter Name Description Default
|
|
-------------- ----------- -------
|
|
oplock contention limit Removed
|
|
|
|
NT4-style replication based net commands removed
|
|
================================================
|
|
|
|
The following commands and sub-commands have been removed from the
|
|
"net" utility:
|
|
|
|
net rpc samdump
|
|
net rpc vampire ldif
|
|
|
|
Also, replicating from a real NT4 domain with "net rpc vampire" and
|
|
"net rpc vampire keytab" has been removed.
|
|
|
|
The NT4-based commands were accidentially broken in 2013, and nobody
|
|
noticed the breakage. So instead of fixing them including tests (which
|
|
would have meant writing a server for the protocols, which we don't
|
|
have) we decided to remove them.
|
|
|
|
For the same reason, the "samsync", "samdeltas" and "database_redo"
|
|
commands have been removed from rpcclient.
|
|
|
|
"net rpc vampire keytab" from Active Directory domains continues to be
|
|
supported.
|
|
|
|
vfs_aio_linux module removed
|
|
============================
|
|
|
|
The current Linux kernel aio does not match what Samba would
|
|
do. Shipping code that uses it leads people to false
|
|
assumptions. Samba implements async I/O based on threads by default,
|
|
there is no special module required to see benefits of read and write
|
|
request being sent do the disk in parallel.
|
|
