relicense to LGPLv2.1 (with exceptions) We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends. 2012-04-12 06:20:58 +08:00			`# under the terms of the GNU Lesser General Public License as published by`

coredump: rely on /proc exclusively to get the name of the crashing process I couldn't see any reason why the kernel could provide COMM to the coredump handler via the core_pattern command line but could not make it available in /proc. So let's assume that this info is always available in /proc. For "backtrace" mode (when --backtrace option is passed), I assumed that the crashing process still exists at the time systemd-coredump is called. Also changing the core_pattern line is an API breakage for any users of the backtrace mode but given that systemd-coredump is installed in /usr/lib/systemd, it's a private tool which has no internal users. At least no one complained when the hostname was added to the core_pattern line (f45b8015513)... Indeed it's much easier to get it from /proc since the kernel substitutes '%e' specifier with multiple strings if the process name contains spaces (!). 2019-06-21 19:12:41 +08:00			`kernel.core_pattern=\|@rootlibexecdir@/systemd-coredump %P %u %g %s %t %c %h`
