Comment 1 Sergei Trofimovich (RETIRED) gentoo-dev 2020-06-06 21:10:44 UTC
The failure seems to be related to test failure in key-material-dtls. As it test somehow manages to kill it's parent(s).

Test failure looks slightly unusual even if ran not under sandbox:

"""
catbus ~/gnutls # time make check -j1
...
PASS: version-checks
make[4]: *** Deleting file 'key-material-dtls.log'
make[1]: *** [Makefile:8489: check-recursive] Terminated

Comment 2 Sergei Trofimovich (RETIRED) gentoo-dev 2020-06-06 23:15:40 UTC
I think kill(child, SIGTERM) happens at: https://gitlab.com/gnutls/gnutls/-/blob/master/tests/key-material-dtls.c#L82

if child is not initialized it happens to kill full process group. Looks like a bug in test suite.

I'll see if sandbox creates new process group for child process.

gnutls-3.6.14-too-broad-SIGTERM.patch

At least with gnutls-3.6.14-too-broad-SIGTERM.patch applied 'make' is not killed in the middle of the test suite.

I think regardless of sandbox handling of SIGTERM from children test should try harder not to kill neighboring tests when test itself fails.

gnutls probably needs fixing more tests like that.

I suggest not to fix sandbox cosmetics.
