Hi @ansisatteka,
Thanks for the report. I have tried to reproduce to the problem, but it seems that it works fine with suricata
.
It'd be helpful to share how to reproduce the problem including source download, build, and tracing with uftrace.
Do you see the problem only on Ubuntu 18.04 LTS version?
On Ubuntu 18.04.3 LTS X86_64 I have built
suricata
with-pg
flag. However, theuftrace replay
command fails:After digging deeper I noticed that the
uftrace.data/pid.dat
file was not created when I ran theuftrace record
command:The
uftrace record
output:I am able to successfully trace other processes than suricata, so I am wondering if this may have something to do with what suricata does? If it helps then
shmem_buf->size
is always zero when I trace suricata, and when I successfully trace other processes it is non-zero.
