machdep.cacheline_size is an integer, not a long. Since PowerPC is
big-endian this causes sysctlbyname() to fill in the upper bits of the
argument, rather than the correct 'lower bits' of the word. Specify the
correct type to fix this.

From: Kashyap Chamarthy <kchamart@redhat.com>
When QEMU exposes a VirtIO-RNG device to the guest, that device needs a
source of entropy, and that source needs to be "non-blocking", like
`/dev/urandom`. However, currently QEMU defaults to the problematic
`/dev/random`, which on Linux is "blocking" (as in, it waits until
sufficient entropy is available).
Why prefer `/dev/urandom` over `/dev/random`?
---------------------------------------------
The man pages of urandom(4) and random(4) state:
"The /dev/random device is a legacy interface which dates back to a
time where the cryptographic primitives used in the implementation
of /dev/urandom were not widely trusted. It will return random
bytes only within the estimated number of bits of fresh noise in the
entropy pool, blocking if necessary. /dev/random is suitable for
applications that need high quality randomness, and can afford
indeterminate delays."
Further, the "Usage" section of the said man pages state:
"The /dev/random interface is considered a legacy interface, and
/dev/urandom is preferred and sufficient in all use cases, with the
exception of applications which require randomness during early boot
time; for these applications, getrandom(2) must be used instead,
because it will block until the entropy pool is initialized.
"If a seed file is saved across reboots as recommended below (all
major Linux distributions have done this since 2000 at least), the
output is cryptographically secure against attackers without local
root access as soon as it is reloaded in the boot sequence, and
perfectly adequate for network encryption session keys. Since reads
from /dev/random may block, users will usually want to open it in
nonblocking mode (or perform a read with timeout), and provide some
sort of user notification if the desired entropy is not immediately
available."
And refer to random(7) for a comparison of `/dev/random` and
`/dev/urandom`.
What about other OSes?
----------------------
`/dev/urandom` exists and works on OS-X, FreeBSD, DragonFlyBSD, NetBSD
and OpenBSD, which cover all the non-Linux platforms we explicitly
support, aside from Windows.
On Windows `/dev/random` doesn't work either so we don't regress.
This is actually another argument in favour of using the newly
proposed 'rng-builtin' backend by default, as that will work on
Windows.
- - -
Given the above, change the entropy source for VirtIO-RNG device to
`/dev/urandom`.

I don't see how this series can introduce a memory leak... all changes
are trivial and there is no memory allocation added.
So I guess it's a false positive. Any idea?
Thanks,

Unrelated to your series, this commit:
commit c82c7336de58876862e6b4dccbda29e9240fd388
Author: BALATON Zoltan <balaton@eik.bme.hu>
Date: Thu Jun 20 12:55:23 2019 +0200
ati-vga: Implement DDC and EDID info from monitor
added a call to bitbang_i2c_init() which has some leak.
It was here since 3cd035d863 "GPIO I2C rework" introduced 'Fri Nov 20
23:37:15 2009', but since then the device-introspect test never run a
machine using this device.
Peter sent a fix for this earlier this morning:
"hw/i2c/bitbang_i2c: Use in-place rather than malloc'd
bitbang_i2c_interface struct"

Hi; this makes 'make check' fail on OSX:
MALLOC_PERTURB_=${MALLOC_PERTURB_:-$(( ${RANDOM:-0} % 255 + 1))}
tests/test-char -m=quick -k --tap < /dev/null |
./scripts/tap-driver.pl --test-name="test-char"
Assertion failed: ((isize & (isize - 1)) == 0), function
init_cache_info, file
/Users/pm215/src/qemu-for-merges/util/cacheinfo.c, line 179.
I guess this is the sys_cache_info change.
thanks

OK, I will try to reproduce the problem.
I think before this patch (regarding the kind of change we have
introduced) isize and dsize were always set to 0 and then changed to 16
in fallback_cache_info()... or perhaps MacOS X sysctlbyname() needs a long.
Is there a HOWTO explaining how to build QEMU on MacOS X?
I'm going to resend the PR without this patch.
Thank you,
Laurent

https://wiki.qemu.org/Hosts/Mac though I think it's a little out of
date now. The short answer is "osx 10.12 or better, use homebrew
to install QEMU's dependencies, then just configure and make
the same as for a Linux host".

It seems MacOS X (x86_64) needs a long:
#include <stdio.h>
#include <sys/types.h>
#include <sys/sysctl.h>
int main(void)
{
long size;
int ret;
size_t len = sizeof(size);
ret = sysctlbyname("hw.cachelinesize", &size, &len, NULL, 0);
printf("ret %d size 0x%lx\n", ret, size);
return 0;
}
$ cc -o cachesize cachesize.c
$ ./cachesize
ret 0 size 0x40
#include <stdio.h>
#include <sys/types.h>
#include <sys/sysctl.h>
int main(void)
{
int size;
int ret;
size_t len = sizeof(size);
ret = sysctlbyname("hw.cachelinesize", &size, &len, NULL, 0);
printf("ret %d size 0x%x\n", ret, size);
return 0;
}
$ cc -o cachesize cachesize.c
$ ./cachesize
ret 0 size 0x1737b1d2
$ sysctl hw.cachelinesize
hw.cachelinesize: 64
But man page is not up-to-date:
$ uname -r
17.7.0
$ man sysctl
SYSCTL(8) BSD System Manager's Manual SYSCTL(8)
…
The string and integer information is summarized below. For a detailed
description of these variable see sysctl(3).
The changeable column indicates whether a process with appropriate privi-
lege can change the value. String and integer values can be set using
sysctl.
Name Type Changeable
…
hw.cachelinesize integer no
…
In fact, it is in sysctl(3):
SYSCTL(3) BSD Library Functions Manual SYSCTL(3)
…
CTL_HW
The string and integer information available for the CTL_HW level is
detailed below. The changeable column shows whether a process with
appropriate privilege may change the value.
Name Type Changeable
...
hw.cachelinesize int64_t no
I will try to check on MacOS/X ppc and ppc64.
Thanks,
Laurent

It's not listed in the man page for ppc(64), but examining the XNU
source for the version that matches 10.5.8 (last ppc-supporting kernel)
it's a CTLTYPE_INT. So, it may be different depending on arch and/or
OS X version. Does QEmu even support 10.5.x or Mac OS/ppc* anymore? I
had read somewhere that it was unsupported now (2.4.x is the latest one
in Tigerbrew).

in bsd/sys/sysctl.h, for latest xnu (xnu-4903.221.2, 10.14.1), I have also CTLTYPE_INT.
I think the thing to do is change the type only for FreeBSD and keep "long" for APPLE.
Thanks,
Laurent
