[Bug 56835] New: memory allocation error in wine9.0

Bug ID: 56835
           Summary: memory allocation error in wine9.0
           Product: Wine
           Version: 9.0
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Our program can run using Wine 8.0, but because Wine 8.0 does not sufficiently
support the WinPcap library, it exits the function directly after calling
pcap_loop without listening to the network card. Therefore, we plan to use Wine
9.0. We tested it with a test program, and it did not have this issue. However,
when running our software, we encountered the following error log:
‘0104:err:virtual:map_view anon mmap error Cannot allocate memory, size
0x3c141000, unix_prot 0x1’. Could this be due to some configuration issue?

The C program is designed to validate the functionality of WinPcap, and it’s
unrelated to the error mentioned in the title.

Thanks, could you also attach a compiled program? Are you using a new style
wow64 build?

Sorry, due to network restrictions, I am unable to upload binary programs. I am
using MinGW GCC on Windows to compile. I downloaded the WinPcap development
package and placed ‘demo.c’ inside. I ran the command ‘gcc demu.c -o demu.exe
-I./Include/ -L./Lib/x64/ -lwpcap -g’

It works fine here on current git Wine. Can you attach a WINEDEBUG=+wpcap log?

In the latest version 9.0, there is no issue with WinPcap library support; this
problem appeared in Wine 8.0. However, in Wine 9.0, there is a memory
allocation problem when running our Windows program. So, I encountered two
different issues in two versions: the WinPcap library support problem in Wine
8.0 and the memory allocation problem in Wine 9.0.

There were many changes in this dll since 8.0. I recommend using Wine 9.0. Can
you attach a log from that version?

What type of logs are needed for the memory allocation failure issue that
occurs in Wine 9.0?

Let's start with WINEDEBUG=+wpcap.

root@mushu:~# WINEDEBUG=fixme-all,+wpcap /usr/lib/wine/wine
winosp_release/winospexe/winosp.exe "C:\ProgramData\ne1\WINOSPHARDCFG.INI"
0024:warn:wpcap:DllMain failed to enable 32-bit mmap() "Unknown options
specified"
0108:err:virtual:map_view anon mmap error Cannot allocate memory, size
0x3c141000, unix_prot 0x1

The above is the output log. Is it possible that the WinPcap issue and the
memory allocation error are two separate problems?

Following is my attempt to compile the test program and run it with
needed capabilities without being root:

cd .wine/drive_c

wget https://npcap.com/dist/npcap-sdk-1.13.zip
unzip -d npcap-sdk npcap-sdk-1.13.zip

wget "https://bugs.winehq.org/attachment.cgi?id=76647" -O winpcap_demo.c
x86_64-w64-mingw32-gcc \
    -g -O2 \
    -Inpcap-sdk/Include \
    -Lnpcap-sdk/Lib/x64 \
    winpcap_demo.c \
    -lwpcap \
    -o winpcap_demo_x86_64
i686-w64-mingw32-gcc \
    -g -O2 \
    -Inpcap-sdk/Include \
    -Lnpcap-sdk/Lib \
    winpcap_demo.c \
    -lwpcap \
    -o winpcap_demo_i686

sudo setpriv \
    --inh-caps '-all,+net_raw,+net_admin' \
    --bounding-set '-all,+net_raw,+net_admin' \
    --reuid=benutzer \
    --ambient-caps='+net_raw,+net_admin' \
    env -i HOME=$HOME /bin/bash --login -i

WINEDEBUG=+wpcap wine winpcap_demo_x86_64

WINEDEBUG=+wpcap wine winpcap_demo_i686

With the 32-bit build and +wpcap the "Unknown options specified" is visible,
and tracing network packets seems to work.

So the issue in winosp.exe with wine-9.0 seems not to be covered by the
winpcap_demo.c reproducer.

This size of 0x3c141000 seems to be nearly a quarter of the whole
address space of a 32-bit process, which would need to be available
in one contiguous block?
Maybe there is some setting to tell the application to map less memory?
Or maybe there is a 64-bit version available?

That's expected. PCAP_MMAP_32BIT is only needed in a new WoW64 build.

Assuming this works on Windows it would be interesting to try a new WoW64
build. Perhaps enough memory will be available there when native libraries are
mapped above the 32-bit limit.
