From c79706af4e7475bf58861a143b77b77a54e7a1cd Mon Sep 17 00:00:00 2001

Subject: [PATCH] api: Add new API nbd_set_pread_initialize()
The recent patch series for CVE-2022-0485 demonstrated that when
applications using libnbd are not careful about error checking, the
difference on whether a data leak is at least sanitized (all zeroes,
partial reads, or data leftover from a prior read) vs. a dangerous
information leak (uninitialized data from the heap) was partly under
libnbd's control. The previous two patches changed libnbd to always
sanitize, as a security hardening technique that prevents heap leaks
no matter how buggy the client app is. But a blind memset() also adds
an execution delay, even if it doesn't show up as the hot spot in our
profiling when compared to the time spent with network traffic.
At any rate, if client apps choose to pre-initialize their buffers, or
otherwise audit their code to take on their own risk about not
dereferencing a buffer on failure paths, then the time spent by libnbd
doing memset() is wasted; so it is worth adding a knob to let a user
opt in to faster execution at the expense of giving up our memset()
hardening on their behalf.
In addition to adding two new APIs, this patch also causes changes to
the four existing APIs nbd_{aio_,}pread{,_structured}, with those
generated lib/api.c changes looking like:

%description
NBD — Network Block Device — is a protocol for accessing Block Devices
(hard disks and disk-like things) over a Network.
This is the NBD client library in userspace, a simple library for
writing NBD clients.
The key features are:
* Synchronous and asynchronous APIs, both for ease of use and for
writing non-blocking, multithreaded clients.
* High performance.
* Minimal dependencies for the basic library.
* Well-documented, stable API.
* Bindings in several programming languages.
