[PATCH v2 0/9] Alpine Linux build fix and CI pipeline

[PATCH v2 0/9] Alpine Linux build fix and CI pipeline

[Jiaxun Yang]

Alpine Linux is a security-oriented, lightweight Linux distribution
based on musl libc and busybox.

It it popular among Docker guests and embedded applications.

Adding it to test against different libc.

Patches pending review at v2 are: 7, 8, 9

Tree avilable at: https://gitlab.com/FlyGoat/qemu/-/commits/alpine_linux_v2
CI All green: https://gitlab.com/FlyGoat/qemu/-/pipelines/242003288

It is known to have checkpatch complains about identation but they're
all pre-existing issues as I'm only doing string replacement. 

v2:
 - Reoreder patches (Wainer)
 - Add shadow to dockerfile (Wainer)
 - Pickup proper signal.h fix (PMM)
 - Correct clock_adjtime title (Thomas Huth)
 - Collect review tags

[PATCH v2 1/9] configure: Add sys/timex.h to probe clock_adjtime

[Jiaxun Yang]

It is not a part of standard time.h. Glibc put it under
time.h however musl treat it as a sys timex extension.

[PATCH v2 3/9] osdep.h: Remove <sys/signal.h> include

[Jiaxun Yang]

From: Michael Forney <mforney@mforney.org>

Prior to 2a4b472c3c, sys/signal.h was only included on OpenBSD
(apart from two .c files). The POSIX standard location for this
header is just <signal.h> and in fact, OpenBSD's signal.h includes
sys/signal.h itself.

Unconditionally including <sys/signal.h> on musl causes warnings
for just about every source file:

  /usr/include/sys/signal.h:1:2: warning: #warning redirecting incorrect #include <sys/signal.h> to <signal.h> [-Wcpp]
      1 | #warning redirecting incorrect #include <sys/signal.h> to <signal.h>
        |  ^~~~~~~

Since there don't seem to be any platforms which require including
<sys/signal.h> in addition to <signal.h>, and some platforms like
Haiku lack it completely, just remove it.

Tested building on OpenBSD after removing this include.

Here you renamed all definitions, better.

[PATCH v2 6/9] tests: Rename PAGE_SIZE definitions

[Jiaxun Yang]

As per POSIX specification of limits.h [1], OS libc may define
PAGE_SIZE in limits.h.

Self defined PAGE_SIZE is frequently used in tests, to prevent
collosion of definition, we give PAGE_SIZE definitons reasonable
prefixs.

Clearer renaming TEST_PAGE_SIZE and TEST_MEM_SIZE.

If possible using TEST_PAGE_SIZE / TEST_MEM_SIZE:

[PATCH v2 7/9] accel/kvm: avoid using predefined PAGE_SIZE

[Jiaxun Yang]

As per POSIX specification of limits.h [1], OS libc may define
PAGE_SIZE in limits.h.

PAGE_SIZE is used in included kernel uapi headers.

To prevent collosion of definition, we discard PAGE_SIZE from
defined by libc and take QEMU's variable.

Is this really needed ? We don't install kernel-headers on other

bison and flex were required to avoid some warnings in the past while 
compiling the dtc submodule ... but I thought we got rid of the problem at 
one point in time, so this can be removed now, indeed.

Looking at the "Depends" list on 
https://pkgs.alpinelinux.org/package/v3.3/main/x86/build-base there are only 
6 dependencies and we need most of those for QEMU anyway, so I think it is 
ok to keep build-base here.

I can remove the superfluous packages when picking up the patch, no need to 
respin just because of this.

I would like to keep them all explicit, as it makes it easier for us to
ensure that we have provided the same set of dependancies across all our
dockerfiles. Ideally we'll add Alpiine to libvirt-ci, so that we can then
auto-generate this dockerfile in future.

Ok, so this is required by the docker.py commands running extra tools.

The other dockerfiles are working just by luck, and we should make this
package expicit on all of them too

You can refer to my post earlier this January for a "minimal" Alpine 
Linux build, if you wish.

My goal was to find the smallest set of packages possible without 
passing any explicit configure flags.

I wonder if it's worth having layered "core build" and "test build" 
images so that we can smoke test the minimalistic build from time to 
time -- I seem to recall Dan posting information about a dependency 
management tool for Dockerfiles, but I admit I didn't look too closely 
at what problem that solves, exactly.

I'd rather we avoid layered images entirely as it creates extra stages
in the gitlab pipeline, and also makes it more complex to auto-generate.

Once this initial alpine image is merged, then I intend to add it to the
set which are auto-generated from my other patch series.

[PATCH v2 9/9] gitlab-ci: Add alpine to pipeline

We only run build test and check-acceptance as their are too many
failures in checks due to minor string mismatch.

Can you give real examples of what's broken here, as that sounds
rather suspicious, and I'm not convinced it should be ignored.

I haven't tried, but I guess it's the "check-block" iotests that are likely 
failing with a different libc, since they do string comparison on the 
textual output of the tests. If that's the case, it would maybe be still ok 
to run "check-qtest" and "check-union" on Alpine instead of the whole 
"check" test suite.

Perhaps errno strings are different due to libc hitting block tests. I
would expect this to be explained in the commit message though with
example, so we have a clear record of why we needed to disable this.

It might indicate a need to change our test suite to be more robust
in this area, because that would also suggest the tests might fail
on  non-Linux.

Daniel

Mostly Input/Output error vs I/O Error.

Right, out of curiosity, I also gave it a try:

  https://gitlab.com/huth/qemu/-/jobs/969225330

Apart from the "I/O Error" vs. "Input/Output Error" difference, there also 
seems to be a problem with "sed" in some of the tests.

Jiaxun, I think you could simply add a job like this instead:

check-system-alpine:
   <<: *native_test_job_definition
   needs:
     - job: build-system-alpine
       artifacts: true
   variables:
     IMAGE: alpine
     MAKE_CHECK_ARGS: check-qtest check-unit check-qapi-schema check-softfloat

That will run all the other tests, without the problematic check-block part.

The "sed" thing sounds like something that ought to be investigated
from a portability POV rather than ignored.

More worrying is the fact that there's a segv in there too when
running qemu-img, which does not give me confidence in use of
it with musl.

The weird thing is that we explicitly test for GNU sed in 
tests/check-block.sh and skip the iotests if it's not available... so I'm a 
little bit surprised that the iotests are run here with an apparently 
different version of sed...?

Oh, well, I've fired up a bootable ISO image of Alpine, and ran "sed 
--version" and it says:

  This is not GNU sed version 4.0

Ouch. But I guess we could add a check for that to our tests/check-block.sh 
script, too...
