Bug ID: 27653
Summary: linux command will be deadlock when linked with
libasan
Product: glibc
Version: 2.30
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: libc
Assignee: unassigned at sourceware dot org
Reporter: hndxvon at 163 dot com
CC: drepper.fsp at gmail dot com
Target Milestone: ---
Host: arm64 Kunpeng920
Build: Gcc-9.2 Glibc-2.30
Hello,
centos seems to be incompatible with libasan(8.0.1).
Run a linux command(like ps,free) with LD_PRELOAD envrionable variable on
centos aarch64 kunpeng920 (gcc-9.2/glibc-2.30),
It will locked.
Run my scripts:
export ASAN_OPTIONS=detect_leaks=0:halt_on_error=0
export LD_LIBRARY_PATH=/usr/lib64/clang/8.0.1/lib/
export LD_PRELOAD=/lib64/clang/8.0.1/lib/libclang_rt.asan-aarch64.so
ps
------------------------------------------------------------------------
(gdb) bt
#0 0x0000ffffb244ecd8 in pthread_rwlock_wrlock () from /lib64/libpthread.so.0
#1 0x0000ffffb279501c in textdomain () from /lib64/libc.so.6
#2 0x0000ffffb29f72a0 in __interceptor_textdomain (domainname=0x40cab8
"procps-ng") at
../lib/asan/../sanitizer_common/sanitizer_common_interceptors.inc:413
#3 0x0000000000402b10 in main ()
(gdb) info threads
Id Target Id Frame
* 1 Thread 0xffffb2126480 (LWP 25205) "ps" 0x0000ffffb279501c in textdomain
() from /lib64/libc.so.6
There is only one thread. how could it generate deadlock?
But unset LD_PRELOAD, ps runs ok.
Try update compiler-rt to 10.0.0, this deadlock still exists.
Thank you for helping.

Please report that to the llvm project. The ASAN runtime calls dlerror (which
uses gettext) during init, which causes a deadlock.

This bug was incorrectly triaged. The glibc i18n code uses non-recursive locks,
and causes issues when malloc interposers perform a i18n translation lookup.
This happens when dlsym() fails.

Just to confirm, did you test the interceptor library work-around or the glibc
fix I submitted here:
https://sourceware.org/pipermail/libc-alpha/2021-August/130129.html ?
About the glibc fix, the mailing list discussion is ongoing with the glibc
maintainers.

Under Debian/unstable (Debian package libc6 2.33-7), when running some
executables with LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libasan.so.6, I can also
see this issue. The gdb backtrace shows __futex_abstimed_wait_common64 /
__GI___futex_abstimed_wait64 / __pthread_rwlock_wrlock_full64 /
__GI___pthread_rwlock_wrlock / set_binding_values in each case.

Same issue here, glibc 2.35-6 and clang 14. I tried the interposer library fix
but couldn't make it work - for some reason whichever libasan.so I try to
preload I get issues:
LD_PRELOAD=/usr/lib/gcc/x86_64-pc-linux-gnu/11.3.0/libasan.so:/home/jcelerier/libasan-glibc-fix.so
./ossia-score
==19609==Your application is linked against incompatible ASan runtimes.
LD_PRELOAD=/usr/lib/clang/14.0.6/lib/linux/libclang_rt.asan-x86_64.so:/home/jcelerier/libasan-glibc-fix.so
./ossia-score
==19481==Your application is linked against incompatible ASan runtimes.
If I don't add the asan runtime I still get the hang..
