* [PATCH AUTOSEL 4.14 22/27] Tools: hv: kvp: eliminate 'may be used uninitialized' warning
From: Sasha Levin @ 2019-08-29 18:16 UTC (permalink / raw)
To: linux-kernel, stable; +Cc: Vitaly Kuznetsov, Sasha Levin, linux-hyperv
In-Reply-To: <20190829181655.8741-1-sashal@kernel.org>
From: Vitaly Kuznetsov <vkuznets@redhat.com>
[ Upstream commit 89eb4d8d25722a0a0194cf7fa47ba602e32a6da7 ]
When building hv_kvp_daemon GCC-8.3 complains:
hv_kvp_daemon.c: In function ‘kvp_get_ip_info.constprop’:
hv_kvp_daemon.c:812:30: warning: ‘ip_buffer’ may be used uninitialized in this function [-Wmaybe-uninitialized]
struct hv_kvp_ipaddr_value *ip_buffer;
this seems to be a false positive: we only use ip_buffer when
op == KVP_OP_GET_IP_INFO and it is only unset when op == KVP_OP_ENUMERATE.
Silence the warning by initializing ip_buffer to NULL.

Functions hv_read_config_block(), hv_write_config_block()
and hv_register_block_invalidate() are not used anywhere
else and are local to drivers/pci/controller/pci-hyperv.c,
and do not need to be in global scope, so make these static.

In-Reply-To: <cover.1567047549.git.brandonbonaby94@gmail.com>
This is a userspace tool to drive the testing. Currently it supports
introducing user specified delay in the host to guest communication
path on a per-channel basis.
Signed-off-by: Branden Bonaby <brandonbonaby94@gmail.com>

Changes in v4:
- Based on Harrys comments, made the tool more
user friendly and added more error checking.
Changes in v3:
- Align python tool to match Linux coding style.
Changes in v2:
- Move testing location to new location in debugfs.

* [PATCH v4 1/2] drivers: hv: vmbus: Introduce latency testing
From: Branden Bonaby @ 2019-08-29 4:24 UTC (permalink / raw)
To: kys, haiyangz, sthemmin, sashal
Cc: Branden Bonaby, linux-hyperv, linux-kernel
In-Reply-To: <cover.1567047549.git.brandonbonaby94@gmail.com>
Introduce user specified latency in the packet reception path
By exposing the test parameters as part of the debugfs channel
attributes. We will control the testing state via these attributes.
Signed-off-by: Branden Bonaby <brandonbonaby94@gmail.com>
---
changes in v4:
- Combined v3 patch 2 into this patch, and changed the
commit description to reflect this.
- Moved debugfs code from "vmbus_drv.c" that was in
previous v3 patch 2, into a new file "debugfs.c" in
drivers/hv.
- Updated the Makefile to compile "debugfs.c" if
CONFIG_HYPERV_TESTING is enabled
- As per Michael's comments, added empty implementations
of the new functions, so the compiler will not generate
code when CONFIG_HYPERV_TESTING is not enabled.
- Added microseconds into description for files in
Documentation/ABI/testing/debugfs-hyperv.
Changes in v2:
- Add #ifdef in Kconfig file so test code will not interfere
with non-test code.
- Move test code functions for delay to hyperv_vmbus header
file.
- Wrap test code under #ifdef statement.

* [PATCH v4 0/2] hv: vmbus: add fuzz testing to hv device
From: Branden Bonaby @ 2019-08-29 4:23 UTC (permalink / raw)
To: kys, haiyangz, sthemmin, sashal
Cc: Branden Bonaby, linux-hyperv, linux-kernel
This patchset introduces a testing framework for Hyper-V drivers.
This framework allows us to introduce delays in the packet receive
path on a per-device basis. While the current code only supports
introducing arbitrary delays in the host/guest communication path,
we intend to expand this to support error injection in the future.
changes in v4:
patch 1:
Combined previous v3 patches 1 and 2, into a single patch
which is now patch 1. This was done so that calls to
the new debugfs functions are in the same patch as
the definitions for these functions.
Moved debugfs code from "vmbus_drv.c" that was in
previous v3 patch 2, into a new file "debugfs.c" in
drivers/hv.
Updated the Makefile to compile "debugfs.c" if
CONFIG_HYPERV_TESTING is enabled
As per Michael's comments, added empty implementations
of the new functions, so the compiler will not generate
code when CONFIG_HYPERV_TESTING is not enabled.
patch 2 (was previously v3 patch 3):
Based on Harrys comments, made the tool more
user friendly and added more error checking.
changes in v3:
patch 2: change call to IS_ERR_OR_NULL, to IS_ERR.
patch 3: Align python tool to match Linux coding style.
Changes in v2:
Patch 1: As per Vitaly's suggestion, wrapped the test code under an
#ifdef and updated the Kconfig file, so that the test code
will only be used when the config option is set to true.
(default is false).
Updated hyperv_vmbus header to contain new #ifdef with new
new functions for the test code.
Patch 2: Moved code from under sysfs to debugfs and wrapped it under
the new ifdef.
Updated MAINTAINERS file with new debugfs-hyperv file under
the section for hyperv.
Patch 3: Updated testing tool with new debugfs location.

Sorry about this. I will fix it in v3. Thank you for pointing this
out.
To address both the alignment and line length of
hv_register_block_invalidate(),
I took a hint from the way how hv_compose_msi_req_v1() is current
formatted. I
hope that this would be acceptable.

Sorry about this. I wasn't sure if one also should wrap compiler and/or
checkpatch.pl script warnings or errors. I will fix this.

At the moment, while compiling the drivers/pci the compiler yields a
similar
warning for the following files:
arch/x86/pci/xen.c
arch/x86/pci/numachip.c
drivers/pci/controller/pci-hyperv.c
drivers/pci/vc.c
I will have a look at each closer.

The second line should be aligned next to the "(" on the first line.
Also the first line is now over 80 chars.

Maybe just:
PCI: hv: Make functions static
since we already know it's in pci-hyperv.c, and it's obvious that you
can only do this for functions that are only used locally.

Does this fix all the similar warnings in drivers/pci/? If there are
more, maybe we could fix them all in a single patch or at least a
single series?

Functions hv_read_config_block(), hv_write_config_block()
and hv_register_block_invalidate() are not used anywhere
else and are local to drivers/pci/controller/pci-hyperv.c,

[Wei Hu]
Actually the original code I sent out just works correctly. It always get
the inclusive rectangle in the above loop, and only send one more extra
line (if y2 == yres) to sythvid_update() and it is clamped inside that
function. Changing it to yres -1 and sending maxy + 1 to sytnvid_update()
makes it the same as the original code in this case, and would end up
always copy and refresh one extra row when y2 < yres.
The comment I added was according to your last review comment asking
to add some comments explaining it. Maybe I mis-understood. I thought
since you wanted me to change to maxy + 1, the code could reach yres + 1
so it will be clamped in synthvid_update() to yres.

The above test seems contradictory to the comment that
says the clamping is done in synthvid_update(). Also, since
the above calculation of y2 is "inclusive", the clamping should
be done to yres - 1 in order to continue to be inclusive. Then
when maxy + 1 is passed to synthvid_update() everything works
out correctly.

Are the tests for less than 0 needed? I think all possibility of
negative values has been eliminated.

The above test isn't needed. The maximum value that y2 can be
is yres (that is checked a few lines above in the big "if" statement).
Since j is always less than y2, j can never be equal to yres.

The changelog for v2 and v3 should actually go after the "---" below so
that the changelog does not end up as part of the commit message. Take
a look at other postings to LKML for an example.

I'm being picky here, but I would call this synthvid_ver_ge(). In my
experience "ge" is the shorthand for "greater than or equal", rather
than the "eg" you have used.

Oh, I see. Yes, this optimization is possible and I'm not against it,
however I doubt it will make a significant difference because no matter
what upon VMCALL we first drop into L0 which can either inject this in
L1 or, in case of direct TLB flush, execute it by itself. Checking if
the hypercall is a TLB flush hypercall is just a register read, it
should be very cheap.

Yes, this won't tigger KVM/Hyper-V hypercall conflict. My point is
that if tlb flush enlightenment is not enabled, enabling direct tlb
flush will not accelate anything and Hyper-V still will check each
hypercalls from nested VM in order to intercpt tlb flush hypercall
But guest won't use tlb flush hypercall in this case. The check
of each hypercall in Hyper-V is redundant. We may avoid the
overhead via checking status of tlb flush enlightenment and just
enable direct tlb flush when it's enabled.

If TLB Flush enlightenment is not exposed to the VM at all there's no
difference if we enable direct TLB flush in eVMCS or not: the guest
won't be using 'TLB Flush' hypercall and will do TLB flushing with
IPIs. And, in case the guest enables Hyper-V hypercall page, it is
definitelly not going to use KVM hypercalls so we can't break these.

Fix the line break.Sorry for noise.
Actually, I had such idea before. But user space should check
whether hv tlb flush is exposed to VM before enabling direct tlb
flush. If no, user space should not direct tlb flush for guest since
Hyper-V will do more check for each hypercall from nested VM
with enabling the feauter..
