Describe the bug
Dynamically loading libcef.so into a running process on Linux arm64 fails since CEF 129 with the error message "cannot allocate memory in static TLS block". Since a lot of CEF wrappers depend on the ability to dynamically extract and load libcef.so (known: CEF4Delphi, JCEF, probably more), this issue effectively makes CEF 129+ unusable for these wrappers on Linux arm64.

To Reproduce
Either use CEF 129 with for example JCEF on Linux, or use the following synthetic console application to dlopen libcef.so:

#include <stdio.h>
#include <dlfcn.h>

int main (void)
{
  void* g_libcef_handle = dlopen("./libcef.so", RTLD_LAZY | RTLD_LOCAL);
  if (!g_libcef_handle) {
    fprintf(stderr, "dlerror %s\n", dlerror());
  }
  return 0;
}

Compile the source code :

g++ -o main.cpp -ldl

Run :

bash-4.4$ ./a.out 
dlerror ./libcef.so: cannot allocate memory in static TLS block
bash-4.4$

Expected behavior
libcef.so can be dynamically loaded into a Linux process.

Screenshots
If applicable, add screenshots to help explain your problem.

Versions (please complete the following information):

  • OS: Linux (all ARM popular distributions)
  • CEF Version: 129.x (6668)

Background/Analysis
The TLS segment size of Chromium 129 increases by over 700 bytes, as can be seen here:

bash-4.4$ readelf -Wl libcef.so | grep -E 'PhysAddr|TLS'
  Type           Offset   VirtAddr           PhysAddr           FileSiz  MemSiz   Flg Align
  TLS            0xc7cc340 0x000000000c7ec340 0x000000000c7ec340 0x000090 0x000430 R   0x40
bash-4.4$

This issue is similar to #3616.

Hi Marshall, do you have a fix for that ?

Does this also impact x64 Intel builds? You can use the tips from #3616 to debug the issue.

Intel x64 versions are not impacted. I will try to debug the issue with these tips and let you as soon as possible a further analysis.

After following tips, here is my analysis :

  • In case of libcef.so (M~129), the output shows that the TLS segment has a file size (FileSiz) of 0x000090 and a memory size (MemSiz) of 0x000430. Thus, the segment size in hex is 0x000430 and equal to 1072 bytes.

  • Earlier versions only had a TLS segment size of 0x0003d8 or 984 bytes. For example, here is the result of the command on libcef.so version M~125 :

 readelf -Wl libcef.so | grep -E 'PhysAddr|TLS'
  Type           Offset   VirtAddr           PhysAddr           FileSiz  MemSiz   Flg Align
  TLS            0xc214fc0 0x000000000c234fc0 0x000000000c234fc0 0x000090 0x0003d8 R   0x40

Here are the two TLS segment results compared side by side:

Property First Result Second Result Difference
Offset 0xc7cc340 0xc214fc0 -
VirtAddr 0x000000000c7ec340 0x000000000c234fc0 -
PhysAddr 0x000000000c7ec340 0x000000000c234fc0 -
FileSiz 0x000090 (144 bytes) 0x000090 (144 bytes) No difference
MemSiz 0x000430 (1072 bytes) 0x0003d8 (984 bytes) 88 bytes (1072 - 984)
Flags R R No difference
Align 0x40 0x40 No difference

Key Differences:

  • The memory size (MemSiz) is different:
    • First result: 1072 bytes (0x000430)
    • Second result: 984 bytes (0x0003d8)
      The difference in size is 88 bytes. Other fields such as Offset, VirtAddr, PhysAddr, FileSiz, and flags remain the same, except for different starting addresses.

Workaround
Just for the record, this workaround works. But it's not acceptable in our case:

export LD_PRELOAD=<FULL-PATH-TO-libcef.so>

And the following patch is already present in config.h:

Deep Investigation
Further investigation found the following usage (.tdata and .tbss are the symbol sections of interest when looking for the actual users of all that TLS space - this article here (A dynamic linker murder mystery) was very helpful in learning interesting tidbits about TLS, and commands to investigate the situation) :

I confirm this issue is present in Ubuntu 24.10 for ARM64 running in a Raspberry Pi 5. The workaround works in this case.

However, the official "Raspberry Pi OS" distribution is not affected by this issue and it's possible to load libcef.so without problems.

All tests were made with CEF 129.0.12 and CEF4Delphi in Lazarus

@Hethsron Thanks for the details. I'm not seeing any large new contributors to MemSiz in your output.

In case of libcef.so (M-129), the output shows [...] a memory size (MemSiz) of 0x000430 [...] libcef.so version M~125 [...] MemSiz 0x0003d8

Can you compare the objdump -t libcef.so | grep -F '.tbss' output more closely between the versions to see where the additional memory usage is coming from? If you can identify a specific new culprit then we can potentially address it. It would be best to compare with M128, or whichever version most recently did not exhibit the problem.

Additionally:

Thus, the segment size in hex is 0x000430 and equal to 1072 bytes.

Whereas, from issue #3616:

The effective surplus allocated by default in x64 Linux (by ld-linux, which is the lib responsible to do this allocation) is sufficient for about 1600 or so bytes.

This suggests that your ARM64 system has a substantially lower threshold than the x64 default. You might want to see if you can adjust that in your system or kernel configuration.
