--- Begin Message ---Package: sysdig Version: 0.26.7-2 Severity: grave Hi. sysdig used to work, but now it doesn't. I'm running Debian/sid, so probably something about my set of dependencies doesn't agree with sysdig, but we should figure out what that is. Earlier today I was seeing a segfault when running some older sysdig package I had installed. I just upgraded sysdig and sysdig-dkms to the latest version available: $ dpkg -l 'sysdig*' ii sysdig 0.26.7-2 amd64 ... ii sysdig-dkms 0.26.7-2 all ... And then I got this: $ sudo sysdig ... sysdig: symbol lookup error: sysdig: undefined symbol: _ZN9grpc_impl23CreateCustomChannelImplERKNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEERKSt10shared_ptrINS_18ChannelCredentialsEERKNS_16ChannelArgumentsE This sounds like #955279, but even if it is, there should be a Conflicts, or something, to prevent me from getting into that state. In any case, I just $ sudo apt install libgrpc++-dev and also upgraded everything that sysdig explicitly depends on, except libc6. And now it segfaults again: $ sudo sysdig zsh: segmentation fault sudo sysdig The backtrace looks like this: #0 0x00005575c7cdd210 in sinsp_parser::reset (this=0x5575c8474ac0, evt=0x5575c8454ce0) at ./userspace/libsinsp/parsers.cpp:717 #1 0x00005575c7ce3f3d in sinsp_parser::process_event (this=0x5575c8474ac0, evt=evt@entry=0x5575c8454ce0) at ./userspace/libsinsp/parsers.cpp:125 #2 0x00005575c7cfa8c9 in sinsp::next (this=0x5575c8454c50, puevt=0x7ffd28e5b0b8) at ./userspace/libsinsp/sinsp.cpp:1290 #3 0x00005575c7c016fc in do_inspect (inspector=0x5575c8454c50, cnt=18446744073709551615, duration_to_tot_ns=0, quiet=false, json=<optimized out>, do_flush=false, print_progress=false, display_filter=0x0, summary_table=std::vector of length 0, capacity 0, formatter=0x7ffd28e5b4e0) at ./userspace/sysdig/sysdig.cpp:604 #4 0x00005575c7c04877 in sysdig_init (argc=<optimized out>, argv=<optimized out>) at ./userspace/sysdig/sysdig.cpp:1596 #5 0x00005575c7bf1fcc in main (argc=<optimized out>, argv=0x7ffd28e5b788) at ./userspace/sysdig/sysdig.cpp:1694 This is inside the sysdig binary itself.

So not entirely sure if rax is parinfo or parinfo->m_val. Anyway... Notes: 1. I upgraded everything sysdig Depends: on except libc6. Upgrading that would force me to upgrade my python, and that makes me touch stuff I'd rather not touch right now 2. I have gcc-10 installed, so that's where the libgcc... and libstdc++... are coming from Is this enough info? -- System Information: Debian Release: buster/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'unstable'), (500, 'stable') Architecture: amd64 (x86_64) Foreign Architectures: arm64, armhf Kernel: Linux 4.17.0-1-amd64 (SMP w/20 CPU cores) Locale: LANG=C, LC_CTYPE=C (charmap=ANSI_X3.4-1968) (ignored: LC_ALL set to C), LANGUAGE=C (charmap=ANSI_X3.4-1968) (ignored: LC_ALL set to C) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages sysdig depends on: ii libb64-0d 1.2-5+b1 ii libc6 2.30-2 ii libcurl4 7.68.0-1 ii libelf1 0.176-1.1 ii libgcc-s1 10.1.0-4 ii libgrpc++1 1.26.0-3 ii libjq1 1.6-1 ii libjsoncpp1 1.7.4-3.1 ii libluajit-5.1-2 2.1.0~beta3+dfsg-5.1 ii libncurses6 6.2-1 ii libprotobuf22 3.11.4-5 ii libssl1.1 1.1.1g-1 ii libstdc++6 10.1.0-4 ii libtbb2 2020.2-2 ii libtinfo6 6.2-1 ii zlib1g 1:1.2.11.dfsg-2 Versions of packages sysdig recommends: ii sysdig-dkms 0.26.7-2 sysdig suggests no packages. -- no debconf information
