RISC-V -- are we ready for more, and what do we need to do it?
by Matthew Miller
Hi all! I just got back from Open Source Summit, several of the talks I
found interesting were on RISC-V -- a high-level one about the
organizational structure, and Drew Fustini's more technical talk.
In that, he noted that there's a Fedora build *, but it isn't an official
Fedora arch. As I understand it, the major infrastructure blocker is simply
that there isn't server-class hardware (let alone hardware that will build
fast enough that it isn't a frustrating bottleneck).
So, one question is: if we used, say, ARM or x86_64 Amazon cloud instances
as builders, could we build fast enough under QEMU emulation to work? We
have a nice early advantage, but if we don't keep moving, we'll lose that.
But beyond that: What other things might be limits? Are there key bits of
the distro which don't build yet? Is there a big enough risc-v team to
respond to arch-specific build failures? And, do we have enough people to do
QA around release time?

fedpkg clone fails with Permission denied (publickey).
by Richard Shaw
Long story short I lost my home directory where I do all of my packager
activities (separate from my main user) so I'm setting things up from
scratch.
I created new ssh keys and uploaded the public key to
admin.fedoraproject.org and pasted into pagure.io. It's been over an hour
and I'm still getting:
$ fedpkg clone hamlib
Cloning into 'hamlib'...
hobbes1069(a)pkgs.fedoraproject.org: Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
Could not execute clone: Failed to execute command.
I've also updated my API tokens, which is STILL not well documented. I
pasted them in the appropriate spot in "/etc/rpkg/fedpkg.conf" which isn't
real intuitive.
Thanks,
Richard

by Igor Gnatenko
It's in redhat-rpm-config-118-1.fc30.
If it causes any problems for you - let me know. In the meantime, you can
use `%undefine _ld_as_needed` to disable it.
Thanks for attention!

Wine MinGW system libraries
by Zebediah Figura
Hello all,
I'm a contributor to the Wine project. To summarize the following mail,
Wine needs special versions of some of its normal dependencies, such as
libfreetype and libgnutls, built using the MinGW cross-compiler, and I'm
sending out a mail to major distributions in order to get some feedback
from our packagers on how these should be built and packaged.
For a long time Wine has built all of its Win32 libraries (DLLs and
EXEs) as ELF binaries. For various reasons related to application
compatibility, we have started building our binaries as PE instead,
using the MinGW cross-compiler. It is our intent to expand this to some
of our dependencies as well. The list of dependencies that we intend to
build using MinGW is not quite fixed yet, but we expect it to include
and be mostly limited to the following:
* libvkd3d
* libFAudio
* libgnutls
* zlib (currently included via manual source import)
* libmpg123
* libgsm
* libpng
* libjpeg-turbo
* libtiff
* libfreetype
* liblcms2
* jxrlib
and dependencies of the above packages (not including CRT dependencies,
which Wine provides).
There is currently some internal discussion about how these dependencies
should be built and linked. There are essentially three questions I see
that need to be resolved, and while these resolutions have a significant
impact on the Wine building and development process, they also have an
impact on distributions, and accordingly I'd like to get input from our
packagers to ensure that their considerations are accurately taken into
account.
(1) Should we build via source import, or link statically, or dynamically?
Static linking and source imports are dispreferred by Fedora [1] [2], as
by many distributions, on the grounds that they cause duplication of
libraries on disk and in memory, and make it harder to update the
libraries in question (see also question 2). They also make building and
bisecting harder.
Note however that if they are linked dynamically, we need to make sure
that we load our packages instead of MinGW builds of open-source
libraries with applications ship with. Accordingly we need each library
to be renamed, and to link to renamed dependencies. For example, if
application X ships with its own copy of libfreetype-6.dll, we need to
make sure that our gdi32.dll links to libwinefreetype-6.dll instead, and
that libwinefreetype-6.dll links to libwineharfbuzz-0.dll and
winezlib.dll. I think, although I haven't completely verified yet, that
this can be done just with build scripts (i.e. no source patches), by
using e.g. --with-zlib=/path/to/winezlib.dll.
Accordingly, although static linking and source imports are generally
disprefered, it may quite likely be preferable in our case. We don't get
the benefits of on-disk deduplication, since Wine is essentially the
only piece of software which needs these libraries.
(2) If we use dynamic libraries, should dependencies be included in the
main wine package, or packaged separately?
This is mostly a question for packagers, although it also relates to (3).
I expect that Fedora (and most distributions) want to answer "packaged
separately" here, on the grounds that this lets them update (say) Wine's
libgnutls separately, and in sync with ELF libgnutls, if some security
fix is needed. There is a snag, though: we need libraries to be copied
into the prefix (there's some internal effort to allow using something
like symlinks instead, but this hard and not done yet). Normally we
perform this copy every time Wine is updated, but if Wine and its
dependencies aren't updated on the same schedule, we may end up loading
an old version of a dependency in the prefix, thus missing the point of
the update.
(3) If dependencies are packaged separately, should Wine build them as
part of its build tree (e.g. using submodules), or find and link
(statically or dynamically) to existing binaries?
Linking to existing binaries is generally preferable: it avoids
duplication on disk; it reduces compile times when compiling a single
package from source (especially the first time). However, we aren't
going to benefit from on-disk duplication. And, most importantly, unlike
with ELF dependencies, there is no standardized way to locate MinGW
libraries—especially if it comes to Wine-specific libraries. We would
need a way for Wine's configure script to find these packages—and
ideally find them automatically, or else fall back to a submodule-based
approach.
If we rely on distributions to provide our dependencies, the best idea I
have here would be something like a x86_64-w64-mingw32-pkg-config. And
if we use shared libraries rather than static, things get worse: we need
to know the exact path of each library and its dependencies so that we
can copy (or symlink) them into a user's WINEPREFIX.
For what it's worth, the current proposed solution (which has the
support of the Wine maintainer) involves source imports and submodules.
There's probably room for changing our approach even after things are
committed, but I'd still like to get early feedback from distributions,
and make sure that their interests are accurately represented, before we
commit. In short, it's not clear whether distributions want their
no-static-library policies to apply to us as well, or whether we're
enough of a special case and would be enough of a pain to package that
they'd rather we deal with the hard parts, and I don't want us to make
any assumptions.
ἔρρωσθε,
Zebediah

Heads-up: grpc 1.41.0 coming to Rawhide with C (core) and C++ soname
bumps
by Ben Beasley
In one week (October 6), or slightly later, I will build grpc 1.41.0 for
Rawhide (F36). Fedora 35 will remain on 1.39.1.
As is traditional for minor releases of grpc, the C++ ABI was broken
(soversion bumped from 1.40 to 1.41). This time, the C (core) ABI was
also broken (soversion bumped from 18 to 19).
I will coordinate builds in a side tag of packages that use the C (core)
and/or C++ libraries. Maintainers of the following packages should have
received this email directly:
• bear
• frr
• perl-grpc-xs
Packages that use the Python bindings should be unaffected, as there
should be no incompatible API changes:
• buildstream
• python-chirpstack-api
• python-etcd3
• python-google-api-core
• python-google-cloud-core
• python-grpc-google-iam
• python-opencensus (orphaned)
• python-opencensus-proto
• python-opentelemetry
• python-pytest-grpc
• python-xds-protos

Release criteria proposal: networking requirements
by Adam Williamson
Hi folks!
So at this week's blocker review meeting, the fact that we don't have
explicit networking requirements in the release criteria really started
to bite us. In the past we have squeezed networking-related issues in
under other criteria, but for some issues that's really difficult,
notably VPN issues. So, we agreed we should draft some explicit
networking criteria.
This turns out to be a big area and quite hard to cover (who'd've
thought!), but here is at least a first draft for us to start from. My
proposal would be to add this to the Basic criteria. I have left out
some wikitext stuff from the proposal for clarity; I'd add it back in
on actually applying the proposed changes. It's just formatting stuff,
nothing that'd change the meaning. Anyone have thoughts, complaints,
alternative approaches, supplements? Thanks!
=== Network requirements ===
Each of these requirements apply to both installer and installed system
environments. For any given installer environment, the 'default network
configuration tools' are considered to be those the installer documents
as supported ways to configure networking (e.g. for anaconda-based
environments, configuration via kernel command line options, a
kickstart, or interactively in anaconda itself are included).
==== Basic networking ====
It must be possible to establish both IPv4 and IPv6 network connections
using DHCP and static addressing. The default network configuration
tools for the console and for release-blocking desktops must work well
enough to allow typical network connection configuration operations
without major workarounds. Standard network functions such as address
resolution and connections with common protocols such as ping, HTTP and
ssh must work as expected.
Footnote titled "Supported hardware": Supported network hardware is
hardware for which the Fedora kernel includes drivers and, where
necessary, for which a firmware package is available. If support for a
commonly-used piece or type of network hardware that would usually be
present is omitted, that may constitute a violation of this criterion,
after consideration of the [[Blocker_Bug_FAQ|hardware-dependent-
issues|normal factors for hardware-dependent issues]]. Similarly,
violations of this criteria that are hardware or configuration
dependent are, as usual, subject to consideration of those factors when
determining whether they are release-blocking
==== VPN connections ====
Using the default network configuration tools for the console and for
release-blocking desktops, it must be possible to establish a working
connection to common OpenVPN, openconnect-supported and vpnc-supported
VNC servers with typical configurations.
Footnote title "Supported servers and configurations": As there are
many different VPN server applications and configurations, blocker
reviewers must use their best judgment in determining whether
violations of this criterion are likely to be encountered commonly
enough to block a release, and if so, at which milestone. As a general
principle, the more people are likely to use affected servers and the
less complicated the configuration required to hit the bug, the more
likely it is to be a blocker.
