Bug ID: 465435
Summary: m_libcfile.c:66 (vgPlain_safe_fd): Assertion 'newfd >=
VG_(fd_hard_limit)' failed.
Classification: Developer tools
Product: valgrind
Version: 3.20.0
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: jsew...@acm.org
Reporter: tin...@noel.tf
Target Milestone: ---
When running crosvm under valgrind, I'm hitting the following assertion:
m_libcfile.c:66 (vgPlain_safe_fd): Assertion 'newfd >= VG_(fd_hard_limit)'
failed.
STEPS TO REPRODUCE
1. I'm using the mesa CI container in Docker as privileged, and I'm running
crosvm in valgrind with crosvm --no-syslog run --gpu
vulkan=true,gles=false,backend=virglrenderer,egl=true,surfaceless=true,width=1024,height=768
--gpu-render-server path=/usr/local/libexec/virgl_render_server -m 4096 -c 2
--disable-sandbox --shared-dir
/:my_root:type=fs:writeback=true:timeout=60:cache=always --host-ip=192.168.30.1
--netmask=255.255.255.0 --mac AA:BB:CC:00:00:12 -p quiet console=null
root=my_root rw rootfstype=virtiofs
ip=192.168.30.2::192.168.30.1:255.255.255.0:crosvm:eth0
init=/mesa/crosvm-init.sh
OBSERVED RESULT
Valgrind stops with ab assert
EXPECTED RESULT
Crosvm to continue to run
