incompatible with PHP8.1 on debian

[ryancinsight]

Using Docker debian bullseye with php8.1 receive a free: invalid pointer error:

root@7ead17e03ea3:/home/snmalloc/out/release# export LD_PRELOAD=/home/snmalloc/out/release/libsnmallocshim.so
root@7ead17e03ea3:/home/snmalloc/out/release# php
free(): invalid pointer
Aborted

free(): invalid pointer

Is not an error message generated by snmalloc. I am guessing that php has statically linked part of the C runtime, or partially overridden the allocator, so that it is not possible to LD_PRELOAD a new allocator.

Could you get a stack trace of the failure? Do other systems like jemalloc or mimalloc work with PHP?

[mjp41]

So I got a stack trace:

So it is not freeing using snmalloc.

I get a similar crash with mimalloc.

[ryancinsight]

jemalloc seems to be working fine and I did find a mimalloc issue on this now: microsoft/mimalloc#377

[mjp41]

So Scudo also crashes. I confirm works. The mimalloc crash is a bit different as it seems to be freeing 0x8.

I got a slightly better stack trace from gdb. I wonder if there is something in libc tail calling _int_free that should be overridden that isn't covered by snmalloc and scudo, but is by jemalloc.

I believe based on the mimalloc issue you link, and skimming the php source, something is being freed with a different kind of allocator to it is being allocated with.

Without building php, so I have the symbols, I am not sure how to proceed. Your valgrind trace shows calls to both libc.so:malloc and libsnmallocshim.so:malloc.

E.g.

--3626-- REDIR: 0x48551b0 (libsnmallocshim.so:malloc) redirected to 0x4838710 (malloc)

and

--3626-- REDIR: 0x527f0f0 (libc.so.6:malloc) redirected to 0x4838710 (malloc)

Given so many allocators are failing, I would suggest it is a PHP problem. That one succeeds is potentially just look that the corruption is not detected.

@ryancinsight apologies for editing your comment, but I couldn't read it with the original formatting.

--3626-- REDIR: 0x527f0f0 (libc.so.6:malloc) redirected to 0x4838710 (malloc)

Given so many allocators are failing, I would suggest it is a PHP problem. That one succeeds is potentially just look that the corruption is not detected.

Indeed, I just tested with jemalloc and had the same errors so it seems they are going undetected with it.

I believe based on the mimalloc issue you link, and skimming the php source, something is being freed with a different kind of allocator to it is being allocated with.
Without building php, so I have the symbols, I am not sure how to proceed. Your valgrind trace shows calls to both libc.so:malloc and libsnmallocshim.so:malloc.
E.g.

--3626-- REDIR: 0x48551b0 (libsnmallocshim.so:malloc) redirected to 0x4838710 (malloc)

and

--3626-- REDIR: 0x527f0f0 (libc.so.6:malloc) redirected to 0x4838710 (malloc)

Those are memory leaks rather than heap corruption. I think Valgrind is replacing both the libc.so:malloc and libsnmalloc.so:malloc with its own implementation. So it would mask what I suspect is the underlying bug.

I wonder if using
https://www.gnu.org/software/libc/manual/html_node/Hooks-for-Malloc.html

Could provide a fix for this. It seems RTLDEEPBIND is the problem in PHP and that doesn't look like it will go away.

This is how jemalloc deals with the problem:

@ryancinsight does this now work for you? #598 I believe should fix this.

It's fixed and working well! I can now share an allocator between containers and images are loading much faster, thanks!
