[igt-dev] [PATCH i-g-t 01/21] lib: Introduce igt_assume()

[Petri Latvala]

igt_assume() is an assert-like macro that is used to give hints to
static analysis of code. If static analysis is not used (as detected
by STATIC_ANALYSIS_BUILD), igt_assume() expands to a no-op statement,
otherwise expands to an assert().

Fair enough. You should definitely steal

/*
 * BUILD_BUG_ON_INVALID() permits the compiler to check the validity of the
 * expression but avoids the generation of any code, even if that expression
 * has side-effects.
 */
#define BUILD_BUG_ON_INVALID(e) ((void)(sizeof((__force long)(e))))

so that #else becomes
#define igt_assume(e) BUILD_BUG_ON_INVALID(e)
so that we plebs don't feed garbage to the static analyzer.

[igt-dev] [PATCH i-g-t v2 01/21] lib: Introduce igt_assume()

[Petri Latvala]

igt_assume() is an assert-like macro that is used to give hints to
static analysis of code. If static analysis is not used (as detected
by STATIC_ANALYSIS_BUILD), igt_assume() expands to a no-op statement,
otherwise expands to an assert().

v2: Make sure the expression in igt_assume is still parsed without
    static analysis. (Chris)

[igt-dev] [PATCH i-g-t v3 01/21] lib: Introduce BUILD_BUG_ON_INVALID and igt_assume()

[Petri Latvala]

BUILD_BUG_ON_INVALID() is a macro that, like the kernel counterpart,
expands to an expression that generates no code. Useful for making
sure an expression is valid code while producing no side effects.

igt_assume() is an assert-like macro that is used to give hints to
static analysis of code. If static analysis is not used (as detected
by STATIC_ANALYSIS_BUILD), igt_assume() expands to a
BUILD_BUG_ON_INVALID, otherwise expands to an assert().

v2: Make sure the expression in igt_assume is still parsed without
    static analysis. (Chris)

v3: Also introduce BUILD_BUG_ON_INVALID as standalone

If an igt_ioctl fails, errno is set to non-zero, and static analysis
doesn't quite get it. Add an igt_assume() to help.

Since we install a custom ioctl func, we could just state it returns
long / ERR_VALUE, matching the kernel ioctl syscall...

[igt-dev] [PATCH i-g-t 04/21] lib/igt_kms: Use correct type for calloc

[Petri Latvala]

The type mismatch was char vs. unsigned char, both being size 1 so
this didn't cause any actual issues other than noise in static
analysis that doesn't believe 1 is equal to another type of 1.

The code assumes (correctly) that perf_event_header's size is

field will be assigned again in the above if blocks. An example test
case for this is:

# cat foo.wsim
a

# gem_wsim_bench -n 1 -w foo.wsim
Segmentation fault

Asserts like that never parse well for me, especiall that
assert_gt(value, 0) seems to be overall more common...

Meybe we should introduce it to IGT?

[Petri Latvala]

if (p) free(p) does a useless check, free(NULL) is a valid call. Also
assign NULL so we don't end up double-freeing memory if anyone
reorders nr_bos to have a 0 after other values.

[igt-dev] [PATCH i-g-t 13/21] lib/igt_alsa: Remove dead assignment

[Petri Latvala]

The execution can only reach the end (goto complete) or the new
unconditional assignment a few lines below before the value is read
again. Either it's really a dead assignment, or there's a bug with the
execution flow. Leaning on the former.

It is indeed a dead assignment and your understanding is correct!

It's not clear to the static analyzer that freq is assigned when
handling the previous frame and then used in the next. In fact, it
wasn't clear to me either before staring at the code for some
minutes. Initializing it to something makes both of us happier.

[igt-dev] [PATCH i-g-t 20/21] lib/igt_x86: Mock-use variable to silence static analysis

[Petri Latvala]

x86_features_to_string() uses a repeatable pattern that increments a
pointer for each feature string, leaving a dead assignment for the
last one. Add a (void)line to the end just to silence static analysis.

Hi,

I tried to apply the patch, and it does not applied directly (I updated
my master before test). I got the following error:

 error: patch failed: lib/drmtest.c:134
 error: lib/drmtest.c: patch does not apply

Anyway, for me, everything is fine with the changes. Additionally, I
tested the patch with:

 Commands:

 IGT_FORCE_DRIVER=vkms ./tests/kms_flip  --run-subtest basic-flip-vs-wf_vblank
 IGT_FORCE_DRIVER= ./tests/kms_flip  --run-subtest basic-flip-vs-wf_vblank
 ./tests/kms_flip  --run-subtest basic-flip-vs-wf_vblank

 Environment:

 -> Qemu VM with Arch linux
 -> GPUs drivers: Bosch (card0) and vkms (card1)
 -> Kernel - 5.0.0-rc1
