net-misc/ntpsec[seccomp] with sys-libs/glibc[nscd] needs to allow the readv() syscall when nscd provides getaddrinfo() support. Otherwise ntpd crashes from time to time with the following stack trace: #0 0x00007f5763bfac4d in readv () from /lib64/libc.so.6 #1 0x00007f5763c48b4c in __readvall () from /lib64/libc.so.6 #2 0x00007f5763c467ed in nscd_gethst_r () from /lib64/libc.so.6 #3 0x00007f5763c46c0d in __nscd_gethostbyname2_r () from /lib64/libc.so.6 #4 0x00007f5763c15a2a in gethostbyname2_r () from /lib64/libc.so.6 #5 0x00007f5763bed3ca in gaih_inet.constprop () from /lib64/libc.so.6 #6 0x00007f5763bee225 in getaddrinfo () from /lib64/libc.so.6 #7 0x000055fcf0ad6544 in open_TCP_socket () #8 0x000055fcf0ad79b4 in nts_probe () #9 0x000055fcf0ac37c4 in dns_lookup () #10 0x00007f5763b8205a in start_thread () from /lib64/libc.so.6 #11 0x00007f5763c05d1c in clone3 () from /lib64/libc.so.6 The (trivial) patch is available upstream at ${URL}.
Thanks.
