File net-snmp-5.7.3-build-with-openssl-1.1.patch of Package net-snmp
From 392e006fc5c64a74ec080b090d02a2d29340494c Mon Sep 17 00:00:00 2001 From: Daniel Molkentin <daniel.molkentin@suse.com> Date: Wed, 22 Mar 2017 14:49:06 +0100 Subject: [PATCH] Backport several fixes from upstream's V5-7-patches branch. Initial support for OpenSSL 1.1 API changes. A slightly modified version from patch 1336, updated to work if you have LibreSSL. There is more work needed to handle TLSTCP and DTLSUDP transports. Thanks to Sharmila Podury. OpenSSL 1.1 fixes for SNMP-USM-DH-OBJECTS-MIB implementation. openssl 1.1.0: Fix several build errors Autodetect DH_get0_pqg() and DH_get0_key() to unbreak the MinGW build. In recent versions of openssl several data structures have been made opaque that were not opaque before. Avoid that attempts to access members of these opaque data structures cause the build to fail. MIBs: Use strlcpy() instead of strcpy() to copy a variable-length string into a fixed-size array apps/snmpusm: Only provide a DH_get0_key() replacement if openssl is available --- agent/mibgroup/disman/event/mteEvent.c | 6 +- agent/mibgroup/disman/event/mteTriggerConf.c | 5 +- agent/mibgroup/disman/schedule/schedCore.c | 17 +-- agent/mibgroup/hardware/cpu/cpu.c | 2 +- agent/mibgroup/hardware/cpu/cpu_linux.c | 2 +- agent/mibgroup/hardware/cpu/cpu_pcp.c | 2 +- agent/mibgroup/hardware/cpu/cpu_sysinfo.c | 2 +- agent/mibgroup/hardware/sensors/hw_sensors.c | 2 +- agent/mibgroup/host/hr_disk.c | 3 +- agent/mibgroup/host/hr_network.c | 2 +- agent/mibgroup/host/hr_swrun.c | 34 +++--- agent/mibgroup/mibII/mta_sendmail.c | 4 +- agent/mibgroup/mibII/system_mib.c | 2 +- agent/mibgroup/mibII/vacm_conf.c | 13 ++- .../usmDHParameters/usmDHParameters.c | 39 ++++++- .../usmDHUserKeyTable/usmDHUserKeyTable_data_get.c | 67 +++++++++++- agent/mibgroup/target/snmpTargetParamsEntry.c | 3 +- agent/mibgroup/ucd-snmp/logmatch.c | 5 +- agent/mibgroup/ucd-snmp/proc.c | 2 +- agent/mibgroup/util_funcs.c | 2 +- agent/mibgroup/util_funcs/get_pid_from_inode.c | 4 +- apps/snmpusm.c | 51 +++++++-- configure | 115 ++++++++++++++++++++- configure.d/config_os_libs2 | 29 +++++- include/net-snmp/net-snmp-config.h.in | 21 ++++ snmplib/keytools.c | 8 +- snmplib/scapi.c | 8 +- snmplib/snmp_openssl.c | 36 +++++-- snmplib/vacm.c | 20 ++-- win32/net-snmp/net-snmp-config.h | 15 +++ win32/net-snmp/net-snmp-config.h.in | 15 +++ 31 files changed, 440 insertions(+), 96 deletions(-) diff --git a/agent/mibgroup/disman/event/mteEvent.c b/agent/mibgroup/disman/event/mteEvent.c index bc4ff0bfb..880520f22 100644 --- a/agent/mibgroup/disman/event/mteEvent.c +++ b/agent/mibgroup/disman/event/mteEvent.c @@ -76,9 +76,7 @@ _init_builtin_mteEvent( const char *event, const char *oname, oid *trapOID, size netsnmp_tdata_row *row;
