Dear All members, We can find following lines in audit/README file LICENSE ======= The audit daemon is released as GPL'd code. The audit daemon's libraries libaudit.* and libauparse.* are released under LGPL so that it may be linked with 3rd party software. I found that latest audit library linked libaucommon.so. ./lib/Makefile.in:AM_CPPFLAGS = -I. -I${top_srcdir} -I${top_srcdir}/auparse -I${top_srcdir}/common ./lib/Makefile.in:libaudit_la_LIBADD = $(CAPNG_LDADD) ${top_builddir}/common/libaucommon.la ./lib/Makefile.in:libaudit_la_DEPENDENCIES = $(libaudit_la_SOURCES) ../config.h ${top_builddir}/common/libaucommon.la ./auparse/Makefile.am:AM_CPPFLAGS = -I. -I${top_srcdir} -I${top_srcdir}/src -I${top_srcdir}/lib -I${top_srcdir}/common ./auparse/Makefile.am:libauparse_la_LIBADD = ${top_builddir}/lib/libaudit.la ${top_builddir}/common/libaucommon.la ./auparse/Makefile.am:libauparse_la_DEPENDENCIES = $(libauparse_la_SOURCES) ${top_builddir}/config.h ${top_builddir}/common/libaucommon.la Libaucommo.so is created by following files ./common/Makefile.am:libaucommon_la_SOURCES = audit-fgets.c strsplit.c And the license of audit/common/audit-fgets.c is GPLv2 This mean the license of latest audit libraries are also GPLv2. Is my understanding correct?
