Bug ID: 54251
           Summary: ipconfig /all hangs / freezes / does not exit
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Used the ArchLinux package managers to install wine-git, which made sure I had
the correct build tools, git cloned, and tracked the files during install.

At least as of 2023-01-01 something's broken with networking.

My PC has two Ethernet ports on the back, and to have the option of using it as
a network switch for my laptop, they're bridged.  I also want my PC to have a
statically leased DHCP address, so the Ethernet bridge configuration might be a
little uncommon, but is not unusual and shouldn't be a problem.

It isn't a problem for ipconfig (no arguments), it isn't a problem for Linux
programs, it isn't a problem for curl under wine.

It _is_ a problem for ipconfig /all and I now suspect (after /all failed) also
a game I purchased during the recent sales.

$ wine-git cmd

The outputs are the same in Proton instances of wine.

While running:

cat "${XDG_RUNTIME_DIR}/winedbg" >/dev/null & printf "%s\n" "${!}" >
"${XDG_RUNTIME_DIR}/winedbg_pid.cat"

kill -9 $(<"${XDG_RUNTIME_DIR}/winedbg_pid.cat") ; cat
"${XDG_RUNTIME_DIR}/winedbg" | tee "${XDG_RUNTIME_DIR}/winedbg_log"

Then beginning stderr output collection just prior to invoking:

ipconfig /all

The log file is _massive_, quickly growing to over 1GB in size.

The most interesting call just before that fitful loop appears to be...

0114:Ret  KERNEL32.GetComputerNameExA() retval=00000001 ret=646c6c8e

$ wc .../winedbg_log
  18522370   64877723 1316392777  .../winedbg_log

ipconfig /all ; does this fail because there is not a 'computer name'
associated with enp8s0 nor enp9s0 ?

https://learn.microsoft.com/en-us/windows/win32/api/sysinfoapi/nf-sysinfoapi...

Given the context GetComputerNameExA's being provided: a static string?,
dynamic return buffer, and a 'DNS domain name of the cluster' sring.

String 2 is likely to be either ComputerNameDnsFullyQualified
ComputerNameDnsHostname.

$ hostname -d
(none)
$ hostname -f
AHOSTNAME
$ hostname -s
AHOSTNAME

I'll double-check if my 'FQDN' hostname is setup correctly; though ipconfig
/all should still not _hang_ but rather behave in a more sensible way.

I've added an IPv4, IPv6 (fd00::/8) and IPv6 (2000::/4) static entries with
local lan info to my /etc/hosts file.

$ hostname -d
lan
$ hostname -f
AHOSTNAME.lan
$ hostname -s
AHOSTNAME

Sadly, updating /etc/hosts / hostname results doesn't seem to help wine.

I've tested it by editing wine-git/PKGBUILD and saving iphlpapi.diff to the
build area's src folder.

# Psueoshell, modify # cp .../iphlpapi.diff ~/.cache/yay/wine-git/src/

Now for the bonus stage... does this fix the game I was trying to play in bug
#54252 ?

$ find ~/.wine -type f -iname 'iphlp*'

$ find ~/.local/share/Steam/ -type f -iname 'iphlp*'

Looks like I'll need to overwrite the file in the compatibility tool, probably
won't be a problem?

~/.local/share/Steam/compatibilitytools.d/GE-Proton7-43/files/lib/wine/i386-windows/iphlpapi.dll
~/.local/share/Steam/compatibilitytools.d/GE-Proton7-43/files/lib64/wine/x86_64-windows/iphlpapi.dll

Also make sure the game's PFX drive uses a symlink not a copied file.
$ ls -l
~/.local/share/Steam/steamapps/compatdata/799600/pfx/drive_c/windows/system*/iphlpapi.dll

Copy the 32 and 64 bit versions of the DLL over their targets in
.local/share/Steam

That allows Costmoteer to boot to the main menu, which it wasn't before.  I
have not yet tested any other aspect of network interaction or gameplay.

When will the patch be in the main / normal git branch?

What version(s) of wine will see a update with or backport of this patch?

Wine is currently in code freeze. I expect development to resume in a couple of
weeks.
