Upgrade issues

Date filed	Issue number	Description
2018-04-13	SPL-153403	After running the "clean userdata" command, admin is unable to login with msg "No users exist. Please set up a new user." Workaround: Create a $SPLUNK_HOME/etc/system/local/user-seed.conf and restart Splunk [user_info] PASSWORD = <yourpassword>
2017-05-23	SPL-141961	Older 6.0, 6.1, 6.2, 6.3 maintenance release versions unable to connect to 6.6.x and later via management port. Workaround: This applies to License Master/Slave, Deployment Server/Client, Cluster Master/Peers, Search Head/Peers and affects Splunk 6.6.x and the following versions: 6.0.0 to 6.0.6 6.1.0 to 6.1.4 6.2.0 to 6.2.6 6.3.0 to 6.3.1 6.3.1511.1 Upgrade your older instances to the latest maintenance releases or on your 6.6.x Splunk instances. Add the following stanza to server.conf: [sslConfig] sslVersions = *,-ssl2 sslVersionsForClient = *,-ssl2 cipherSuite = TLSv1+HIGH:TLSv1.2+HIGH:@STRENGTH
2017-03-20	SPL-139019	Possible compatibility issues between Python / SDK clients and new 6.6 and later default sslVersions, cipherSuites Workaround: Users can do either of the following: 1. Overwrite the new Splunk 6.6 server.conf [sslConfig] sslVersions, cipherSuites with your own settings that are compatible with your version of OpenSSL, e.g. the previous defaults from 6.5.x are compatible with OpenSSL 0.9.8 on Mac OSX: [sslConfig] sslVersions = *,-ssl2 sslVersionsForClient = *,-ssl2 cipherSuite = TLSv1+HIGH:TLSv1.2+HIGH:@STRENGTH 2. For some more up-to-date clients, it is possible to enforce TLS1.2 (e.g. --tlsv1.2 for curl) in order to connect successfully. 3. Upgrade OpenSSL on your platform and link it with your client (e.g. Python, curl, etc..). For example, OpenSSL 1.0.2 is currently available on Mac OSX via Homebrew (see https://brew.sh) and is compatible with the new Splunk 6.6 default sslVersions, cipherSuites.
2017-03-13	SPL-138647	Possible compatibility issues between new 6.6 and later default sslVersions, cipherSuites and external services, e.g. e-mail, LDAP Workaround: If security is not a significant concern, simply revert back to the 6.5.x SSL/TLS defaults, e.g. for e-mail, add to $SPLUNK_HOME/etc/system/local/alert_actions.conf [email] sslVersions = *,-ssl2 cipherSuite = TLSv1+HIGH:TLSv1.2+HIGH:@STRENGTH To configure LDAP with the same settings used by e-mail alerts: $SPLUNK_HOME/etc/openldap/ldap.conf TLS_PROTOCOL_MIN 3.1 TLS_CIPHER_SUITE TLSv1+HIGH:TLSv1.2+HIGH:@STRENGTH To completely revert the LDAP configuration to the 6.5.x SSL/TLS defaults, comment out TLS_PROTOCOL_MIN and TLS_CIPHER_SUITE If you would like to retain the more secure 6.6.x defaults, but prefer to add an exception for your less secure external services, follow the procedure below: 1. To determine what sslVersions and cipherSuites are supported by a server, run splunk cmd openssl s_client -connect hostname:port | awk '/Protocol/ || /Cipher/ || /Verify/'. The example below is for a Postfix SMTP server: eserv@indexer01:~$ splunk cmd openssl s_client -connect smtp-server01:465 | awk '/Protocol/ || /Cipher/ || /Verify/' depth=1 C = US, O = Example Customer, OU = IT, CN = Example Customer IT CA, emailAddress = customer@example.org verify error:num=19:self signed certificate in certificate chain New, TLSv1/SSLv3, Cipher is DHE-RSA-AES256-SHA Protocol : TLSv1 Cipher : DHE-RSA-AES256-SHA Verify return code: 19 (self signed certificate in certificate chain) 2. Check the OpenSSL output for Protocol and Cipher. In the example above, Protocol = TLSv1 and Cipher = DHE-RSA-AES256-SHA 3. Update Splunk's relevant sslVersions and/or cipherSuite. In the example above, sslVersions should be set to tls (allows TLSv1, TLSv1.1, TLSv1.2) and DHE-RSA-AES256-SHA should be appended to the end of the default cipherSuites definition, e.g. add $SPLUNK_HOME/etc/system/local/alert_actions.conf : [email] sslVersions = tls cipherSuites = ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA
2014-08-20	SPL-89640	When running Splunk on Linux as non-root user and using RPM to upgrade, the RPM writes $SPLUNK_HOME/var/log/introspection as root, causing errors upon restarts Workaround: Chown the $SPLUNK_HOME/var/log/introspection directory to the user Splunk Enterprise runs as after upgrading and before restarting Splunk Enterprise.
2013-08-19	SPL-73386	Users are not allowed to run historical scheduled search Workaround: 1. Create a special power/admin user who can run scheduled searches. 2. Assign this user ownership of the scheduled searches. 3. Share the searches at the app level and grant read/write permission to the correct set of users.

Data input issues

2018-06-15	SPL-155648, SPL-169611, SPL-169612, SPL-185656	New phased_execution_mode is spawning extra processes for custom search commands Workaround: If the custom search needs to run only once, disable the multithread for all searches. $SPLUNK/etc/system/local stopped the issue from occurring. [search] phased_execution_mode = auto Apply this workaround especially for deployment using ITSI, as the bug causes double backfill of the ITSI Episodes.

2018-03-15	SPL-152168	Batch-mode retry can return more or less events than it should due to reordering from thread pool processing. Workaround: Before you initiate searchable rolling restart or rolling upgrade, make sure the search_retry attribute in the [search] stanza of limits.conf is set to false (the default). If you have scheduled searches that must complete, either increase the value of decommission_search_jobs_wait_secs (default=180s) in server.conf, or do not run searchable rolling restart or rolling upgrade during the search's timeframe.

Overwrite the new Splunk 6.6 server.conf [sslConfig] sslVersions, cipherSuites with your own settings that are compatible with your version of OpenSSL, e.g. the previous defaults from 6.5.x are compatible with OpenSSL 0.9.8 on Mac OSX: [sslConfig] sslVersions = *,-ssl2 sslVersionsForClient = *,-ssl2 cipherSuite = TLSv1+HIGH:TLSv1.2+HIGH:@STRENGTH 2. For some more up-to-date clients, it is possible to enforce TLS1.2 (e.g. --tlsv1.2 for curl) in order to connect successfully. 3. Upgrade OpenSSL on your platform and link it with your client (e.g. Python, curl, etc..). For example, OpenSSL 1.0.2 is currently available on Mac OSX via Homebrew (see https://brew.sh) and is compatible with the new Splunk 6.6 default sslVersions, cipherSuites.
2017-03-14	SPL-138731	New 6.6 and later default SHA256/2048-bit key certificates are not compatible with previous versions SHA1/1024-bit key certificates if cert verification is enabled Workaround: Users can do any of the following: 1. Disable certificate verification - the same root certificate is available with every Splunk download so enabling certificate verification while using the default certificates provides very little additional security. 2. Generate new SHA256/2048-bit key certificates using the new 6.6 root certificate and distribute to older versions of Splunk 3. Generate SHA1/1024-bit key certificates using the old root certificate to use with your new 6.6 instance. For convenience, the old root certificate is included in 6.6 in $SPLUNK_HOME/etc/auth/prev_release/
2015-06-10	SPL-103010	Indexing throughput on a forwarder with four pipelinesets drops 30% compared to a forwarder with two pipelinesets.
2015-04-14	SPL-99687, SPL-129637	Splunk universal forwarder is 7-10 days behind recent Windows Security and system log events. Workaround: To mitigate this, edit the following stanza in inputs.conf: [WinEventLog://Security] evt_resolve_ad_obj = 0.
2015-04-07	SPL-99316	Universal Forwarders stop sending data repeatedly throughout the day Workaround: In limits.conf, try changing file_tracking_db_threshold_mb in the [inputproc] stanza to a lower value.
2015-03-25	SPL-98594	Routing events to two different groups not working as expected. Workaround: 1 On the original UF, instead of configuring 1 s2s and 1 syslog group, configure 2 s2s groups. 2 Setup a proxy UF which takes input from the original UF and send input out syslog server. This solution only requires config change and no patch release is required.
2014-08-05	SPL-88396	After configuring a client name for a deployment client, the name is not shown in the Forwarder Management UI Workaround: Create a server class, where you can see the client name, and use that group when you add data.
