Description Maciej S. Szmigiero 2020-05-05 23:13:13 UTC

net-misc/ntpsec-1.1.8[seccomp] with sys-libs/glibc-2.31 crashes when it tries to adjust the system clock with the following error logged in syslog:
ntpd[1234]: ERR: SIGSYS: got a trap.                                                                                                                                                       
ntpd[1234]: ERR: SIGSYS/seccomp bad syscall 305/0xc000003e                                                                                                                                 

Syscall 305 is clock_adjtime.

Upstream has actually already fixed this, but in multiple commits touching the same few lines:
https://github.com/ntpsec/ntpsec/commit/afa74426c816a138dfbab89ce294c78bd5863a1b
https://github.com/ntpsec/ntpsec/commit/444796d1e01c43c6fcda04827989738518d748a2
https://github.com/ntpsec/ntpsec/commit/3aff6247842b315bbc4c16c14766530f697b949d
https://github.com/ntpsec/ntpsec/commit/39a880bb232bc2ee6a7187230e7359bcb216fd07

I've attached a small patch that actually merges the effect of these 4 commits.

This fix is only needed up through 1.1.8. Closing since 1.1.9 is stable now.  Sorry I wasn't able to pick this up in a timely fashion.
