JANSI Not Executable In '/tmp' on CENTOS

[clementmark]

Hi All

Wondering if anyone else has experienced a similar issue. I have recently upgraded to JDK 8 and Maven 3.8.5 and when i try mvn --version i get an error as such:

Failed to load native library:jansi-2.4.0-bbb285ac9ffab828-libjansi.so. The native library file at /tmp/jansi-2.4.0-bbb285ac9ffab828-libjansi.so is not executable, make sure that the directory is mounted on a partition without the noexec flag, or set the jansi.tmpdir system property to point to a proper location. osinfo: Linux/x86_64 java.lang.UnsatisfiedLinkError: /tmp/jansi-2.4.0-bbb285ac9ffab828-libjansi.so: /tmp/jansi-2.4.0-bbb285ac9ffab828-libjansi.so: failed to map segment from shared object: Operation not permitted Apache Maven 3.8.5 (3599d3414f046de2324203b78ddcf9b5e4388aa0) Maven home: /opt/apache-maven-3.8.5 Java version: 1.8.0_251, vendor: Oracle Corporation, runtime: /opt/jdk1.8.0_251/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "3.10.0-1160.49.1.el7.x86_64", arch: "amd64", family: "unix"

I have also tried installing JANSI through yum and that does not seem to resolve it. sudo yum -y install jansi-native

Any help or guidance on how to resolve this would be greatly appreciated.

CentOS Linux release 7.9.2009 (Core)

The default installation on CENTOS marks the '/tmp' as nonexec. For security reasons it is not viable to remount '/tmp' as exec. Could this directory be parameterised?

[michael-o]

Oh c'mon, really? I asked you to raise an issue to properly document loading algorithm and not to complain that you have mounted /tmp with noexec. I have provided a proper solution for your problem.

The default installation on CENTOS marks the '/tmp' as nonexec.

This is not true. I have recently installed CentOS 7 and it is not mounted with that option.

Could this directory be parameterised?

Did you actually read my long description what you can do?

Hi Michael,

Thanks for your response albeit non professional. We have had our DevOps team and Security team stating that remounting '/tmp' as exec is a no go for us just to use the latest maven version.

There have been further responses stating the same. I would not advise this either to other people having the same issue.

We have reverted back to using Maven 3.5.0 until this is addressed.

Thanks for your response. (End of conversation)

Hello all,

We have 40 CICD servers using Maven v3.8.6 where JANSI 2.4.0 is used. When our CICD server (Atlassian Bamboo) executes tasks with Maven, it always execute mvn with the parameter -Djava.io.tmpdir=/somecustompath and this path is on a mount point with parameters rw,relatime,attr2,inode64,logbufs=8,logbsize=32k,noquota

However, when maven executes, it shows he warning Failed to load native library:jansi-2.4.0-ead001ff715b1196-libjansi.so. The native library file at /tmp/jansi-2.4.0-ead001ff715b1196-libjansi.so is not executable, make sure that the directory is mounted on a partition without the noexec flag, or set the jansi.tmpdir system property to point to a proper location. osinfo: Linux/x86_64

But I don't understand, because line 80 in https://github.com/fusesource/jansi/blob/jansi-2.4.0/src/main/java/org/fusesource/jansi/internal/JansiLoader.java#L80 shows that default folder would fallback on java.io.tmpdir, but it seems it doesn't.

Do you have an idea why this is happening?

Thank you

Hello @gnodet , can you have a look at this please? I ran Maven with some logs and it shows that Maven is called with the parameter java.io.tmpdir. I don't understand why jansi is not making use of it. Do you have an idea?

@michael-o can you please have a look as well, as Maven is using jansi, which is not behaving corrrectly, and at the end of the day, we are Maven users, we do not care much about the dependencies behind Maven...

Thank you

It's getting even more interesting, the jansi.tmpdir is not taken into account. See below

Without having analyzed it further, you are using a misconception/documentation in Maven which I am going to document/change in Maven 4, maybe even 3.9.0: with mvn ... -Dfoo=bar you do NOT pass a system property, but a user property which unfortunately promoted to a system property. Jansi uses static methods which are run before Maven has a change to set that promoted property.

Please try the following and report: export MAVEN_OPTS=-Djansi.tmpdir=$HOME/tmp; mvn -v

@slawekjaranowski @cstamas @gnodet @hboutemy This is something I told you about that the documentation and mvn -h is plain wrong. You cannot reasonably set system props via the mvn command.

PS: @flopma This isn't your fault. We have failed to update code and docs in time.

[michael-o]

@slawekjaranowski We need fix this is Verifier mid-term and all other components to avoid such cases.

Thx for your prompt feedback Michael. I tried export MAVEN_OPTS=-Djansi.tmpdir=$HOME/tmp; mvn -v and export MAVEN_OPTS=-Djava.io.tmpdir=$HOME/tmp; mvn -v in my case, and indeed, the warning from jansi is gone.

Ok, then your explanation explains everything about the behavior I have. I will try using $HOME/.mavenrc to set a MAVEN_OPTS because the example about is run inside Atlassian Bamboo and it is actually Bamboo which is using the -Djava.io.tmpdir as a maven user property. It seems a lot of users are confused about this. I believe -D parameters like that which are interpreted by Maven should not be automatically set as system properties, because it is then confusing...

I will also open a support case with Atlassian to explain them what you just described...

So I guess there is no bug in jansi. The code is perfectly fine. It's just dummy Maven users :see_no_evil: :sweat_smile:

Thx

There is a better way that setting a custom tempdir. Put the shared library into a separate directory, e.g., /opt/jansi/lib/libjansi.so and set -Dlibrary.jansi.path=/opt/jansi/lib. This will completely avoid the copying and deleting of the shared library and save you startup time. Ideally, the library is on the loader's library path, or alternatively LD_LIBRARY_PATH and you don't need to configure Maven at all. If you go that route, remove the lib form the MAVEN_HOME dir.

Your understanding is absolutely correct. It is a total mess and it most not be promoted because it is not guaranteed to work as people expect. This is the spot which makes everything confusing. I plan to remove this mid term, but until then we need to do a lot of cleanup.
