hi, i came up to a strange problem today with "logger" from util-linux after emerging world. when using logger with the --id switch, it throws the error "logger: send message failed: invalid argument". this happens only if logger gets more than one line via stdin and if the value used for --id is a pid of a currently running process. if logger receives only one line or if the value for --id is not currently associated with a running process, no error is shown and syslogd receives all input without a problem. as a result of the first case only the first line is received by syslogd and logger exits with success (0) anyway. example: $ ( echo 1; echo 2; echo 3; ) | logger --id=$$ logger: send message failed: Das Argument ist ungültig logger: send message failed: Das Argument ist ungültig strace output: (...) read(0, "1\n2\n3\n", 4096) = 6 getpid() = 3302 geteuid32() = 0 kill(30318, SIG_0) = 0 sendmsg(3, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="<13>Nov 10 21:34:11 root[30318]:"..., iov_len=33}, {iov_base="1", iov_len=1}], msg_iovlen=2, msg_control=[{cmsg_len=24, cmsg_level=SOL_SOCKET, cmsg_type=SCM_CREDENTIALS, cmsg_data={pid=30318, uid=134514384, gid=13}}], msg_controllen=24, msg_flags=0}, 0) = 34 getpid() = 3302 geteuid32() = 0 kill(30318, SIG_0) = 0 sendmsg(3, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="<13>Nov 10 21:34:11 root[30318]:"..., iov_len=33}, {iov_base="2", iov_len=1}], msg_iovlen=2, msg_control=[{cmsg_len=24, cmsg_level=SOL_SOCKET, cmsg_type=SCM_CREDENTIALS, cmsg_data={pid=30318, uid=3214637644, gid=4294967295}}], msg_controllen=24, msg_flags=0}, 0) = -1 EINVAL (Invalid argument) write(2, "logger: ", 8logger: ) = 8 write(2, "send message failed", 19send message failed) = 19 write(2, ": ", 2: ) = 2 (...) getpid() = 3302 geteuid32() = 0 kill(30318, SIG_0) = 0 sendmsg(3, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="<13>Nov 10 21:34:11 root[30318]:"..., iov_len=33}, {iov_base="3", iov_len=1}], msg_iovlen=2, msg_control=[{cmsg_len=24, cmsg_level=SOL_SOCKET, cmsg_type=SCM_CREDENTIALS, cmsg_data={pid=30318, uid=3214637644, gid=4294967295}}], msg_controllen=24, msg_flags=0}, 0) = -1 EINVAL (Invalid argument) went back to util-linux-2.28.2, but the problem persists, so i assume the problem relates to the fact that both were built with recent glibc 2.25-r8 which also appeared in portage some days ago. there is a comment in logger.c of util-linux which relates in some kind to my described case: /* syslog/journald may follow local socket credentials rather * than in the message PID. If we use --id as root than we can * force kernel to accept another valid PID than the real logger(1) * PID. */ syslog-ng is the logging daemon here. no systemd used. is there any tip/fix beside downgrading glibc, or can anybody reproduce? thanks a lot, nico Reproducible: Always Steps to Reproduce: ( echo 1; echo 2; echo 3; ) | logger --id=$$; Actual Results: first line is received by logging daemon. error message for each remaining line. Expected Results: all lines received by logging daemon. no error messages.

I am unable to reproduce with >=sys-apps/util-linux-2.31 on an OpenRC system. Can you please try to reproduce with util-linux-2.31 or later?
just tried logger from util-linux-2.31. - same behaviour ("cannot send message...") also tried the following: separate invocation of logger for each line. (works) $ for i in 1 2 3; do echo $i | logger --id=$$; done; simple imitation of logger's job as described yesterday. (works too) $ ( echo 1; echo 2; echo 3; ) | perl -MSys::Syslog -e 'openlog(test,"ndelay,pid", "local0"); syslog(LOG_INFO,$_) while (<>); closelog'; i also temporarily exchanged syslog-ng with sysklogd (same error). current versions for x86: sys-apps/util-linux-2.30.2::gentoo USE="cramfs ncurses pam readline suid unicode -build -caps -fdformat -kill -nls -python (-selinux) -slang -static-libs -systemd {-test} -tty-helpers -udev" PYTHON_SINGLE_TARGET="python2_7 -python3_4 -python3_5 (-python3_6)" PYTHON_TARGETS="python2_7 -python3_4 -python3_5 (-python3_6)" 4.339 KiB sys-libs/glibc-2.25-r9:2.2::gentoo USE="gd rpc -audit -caps -debug (-hardened) (-multilib) -nscd -profile (-selinux) -suid -systemtap (-vanilla)" 13.613 KiB app-admin/syslog-ng-3.7.3::gentoo USE="tcpd -amqp -caps -dbi -geoip -ipv6 -json (-libressl) -mongodb -pacct -python -redis -smtp -spoof-source -systemd" PYTHON_TARGETS="python2_7" 3.429 KiB on amd64/x86_64 platform the problem does NOT occur. the only difference is that there is glibc-2.25-r8 instead of glibc-2.25-r9. (no ~xyz keywords in use).
