1574389327 M * Hurga Hi, I have a little problem here which I don't know how to address... I recently built a new guest, Devuan Beowulf (basically Debian Buster), which starts ok, but when I try to enter it, I get
1574389329 M * Hurga vserver monitor enter
1574389329 M * Hurga /sbin/vcontext: relocation error: /lib/x86_64-linux-gnu/libnss_files.so.2: symbol __libc_readline_unlocked, version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference
1574389390 M * Hurga kernel 4.9.159-vs2.3.9.8, vserver tools 0.30.216-pre3131
1574389596 M * Hurga the host machine is running Devuan ASCII (Debian Stretch basically), libc 2.24-11+deb9u4, the guest has libc 2.28-10 in case it matters. I'm not enough of a dev to know how to debug this...
1574390061 M * Bertl_oO can you run 'vserver-info - SYSINFO' and upload the output to a pastebin?
1574390902 M * Hurga https://pastebin.com/CfBN5yHh
1574392010 M * Bertl_oO well, there is your problem, you did build the tools without dietlibc
1574392050 M * Bertl_oO so when you run 'enter' you bring your glibc from the host into the guest
1574392106 M * Bertl_oO and when it does some name resolving (which is basically loading a dynamic library) you get the one from the guest which isn't compatible
1574392138 M * Bertl_oO rebuild util-vserver with dietlibc and it will work just fine
1574392333 M * Hurga got it, thanks. So far I was able to run very different guest versions though without any issues.
1574392382 M * Bertl_oO well, it might just work if the guest's libc is 'compatible'
1574392412 M * Bertl_oO but in any case it is a potential security risk
1574392434 M * Bertl_oO (i.e. guest libraries being loaded by host binaries :)
1574392641 M * Hurga aand of course it works now just fine. Thanks a lot :)
1574393890 M * Bertl_oO you're welcome!
