Package: barrier Version: 2.1.2+dfsg-1~bpo9+1 Severity: normal Dear Maintainer,
I have Barrier server version 2.1.2+dfsg-1~bpo9+1 on a Debian box and Barrier client version 2.3.3 on a Mac (from Homebrew). After restarting the Mac, Barrier failed to start. Its log says repeatedly: ERROR: ssl error occurred (system call failure) ERROR: failed to connect to secure socket On the Debian system, syslog shows: ERROR: ssl certificate doesn't exist: /home/phil/.local/share/barrier/SSL/Barrier.pem But that file does exist: -rw------- 1 phil phil 2798 Feb 20 2020 /home/phil/.local/share/barrier/SSL/Barrier.pem Investigating with strace: [pid 15729] openat(AT_FDCWD, "/home/phil/.local/share/barrier/SSL/Barrier.pem", O_RDONLY) = -1 EMFILE (Too many open files) So there appears to be an issue with misleading error reporting. Looking at the source: https://github.com/debauchee/barrier/blob/master/src/lib/net/SecureSocket.cpp Line 344 It just checks std::ifstream::good(). At the very minimum, the error message "ssl certificate doesn't exist" should be replaced with "ssl certificate file could not be opened". Much better, it should use errno and e.g. strerror to give a useful message. (Note I'm using an older version of Barrier but I'm looking at the current source code.) I'm continuing to look at what the underlying issue might be. -- System Information: Debian Release: 9.9 APT prefers stable APT policy: (990, 'stable'), (500, 'oldstable-updates'), (500, 'oldstable') Architecture: arm64 (aarch64) Foreign Architectures: armhf Kernel: Linux 3.14.29+ (SMP w/2 CPU cores; PREEMPT) Locale: LANG=en_GB.utf8, LC_CTYPE=en_GB.utf8 (charmap=UTF-8), LANGUAGE=en_GB.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages barrier depends on: ii libavahi-compat-libdnssd1 0.7-4+b1 ii libc6 2.28-10 ii libcurl3 7.52.1-5+deb9u9 ii libgcc1 1:6.3.0-18+deb9u1 ii libice6 2:1.0.9-2 ii libqt5core5a 5.7.1+dfsg-3+deb9u1 ii libqt5gui5 5.7.1+dfsg-3+deb9u1 ii libqt5network5 5.7.1+dfsg-3+deb9u1 ii libqt5widgets5 5.7.1+dfsg-3+deb9u1 ii libsm6 2:1.2.2-1+b3 ii libssl1.1 1.1.0k-1~deb9u1 ii libstdc++6 6.3.0-18+deb9u1 ii libx11-6 2:1.6.4-3+deb9u1 ii libxext6 2:1.3.3-1+b2 ii libxi6 2:1.7.9-1 ii libxinerama1 2:1.1.3-1+b3 ii libxrandr2 2:1.5.1-1 ii libxtst6 2:1.2.3-1 ii openssl 1.1.0k-1~deb9u1 barrier recommends no packages. barrier suggests no packages. -- no debconf information
