You can tune the Java virtual machine (JVM) that runs the mailbox server application by making changes to a few local config variables. However, we strongly recommend that all installations double check their JVM settings based on reviewing and understanding this section. ZCS by default tries to provide best settings for your system. Java runtimes have an automatically garbage collected heap and ZCS maintains caches in the Java heap, and therefore selecting the garbage collector and adjusting the heap size/options are critical to good performance.

In June 2008, Linux distributions represented five of the top ten, FreeBSD three of ten, and Microsoft two of ten;[97] since February 2010, Linux distributions represented six of the top ten, FreeBSD two of ten, and Microsoft one of ten,[98] with Linux in the top position. Linux distributions have long been used as server operating systems, and have risen to prominence in that area; Netcraft reported in September 2006, that eight of the ten (other two with “unknown” OS) most reliable internet hosting companies ran Linux distributions on their web servers,[96] with Linux in the top position.

So there is tui project, and recently postmarketos project appeared. No, I don’t want to do phone `cat addressbook | grep Friend | cut -f 1`. Maemo was slightly closer, and probably could be fixed if it was open-source. There’s emacs org mode, with great calendar capabilities, but I could not find matching application to display data nicely and provide alerts. Android is really far away from normal Unix machine, and I’d argue away from anything usable, too. For a long time, I wanted a phone that runs Unix. Maemo got some parts right, at least you could run old apps in a useful way; but most important data on the phone (contacts, calendar) were still locked away in sqlite. With Android I realized that running Linux kernel is not enough. More is missing in the userspace. Graphical utilities are okay. There’s more to Unix: compatibility with old apps, small programs where each one does one thing well, data in text formats so you can put them in git. (And again, graphical applications would be nice). Nokia N900 is mostly supported by mainline kernel (with exceptions of bluetooth and camera, everything works). And I got that, first Android, second Maemo on Nokia N900. I call it “Unicsy phone”. Situation is even worse for contacts; emacs org can help there, too, but there does not seem to be agreement that this is the way to go. And that is something I’d like to change: phone that is ssh-friendly, text-editor-friendly and git-friendly. Phone parts need work, as expected. But console tools still should be there, and file formats should be reasonable. What is more surprising. There’s work to be done, but it looks doable. But I realized Linux kernel is not really the most important part.

Seccomp improvements
Tyler Hicks addressed a long-standing deficiency in how seccomp could log action results. With these changes in place, it should be much easier for developers to inspect the results of seccomp filters, and for process launchers to generate logs for their child processes operating under a seccomp filter. In addition to creating a way to mark a specific seccomp filter as needing to be logged with SECCOMP_FILTER_FLAG_LOG, he added a new action result, SECCOMP_RET_LOG.

Static binaries are available for downloads, with each individual applet enabled separately, as well as the binary with almost all applets selected, and helper binaries (ssl_helper for HTTPS wget support, index. Cgi and httpd_ssi for HTTP server). Cgi, post_upload.

Tizen is a project within The Linux Foundation. [108] Samsung Z smartphones will use Tizen instead of Android. Several Samsung products are already running Tizen, Samsung Gear 2 being the most significant example. [107] The project was later terminated in favor of Tizen, an operating system targeted at mobile devices as well as IVI. [106] It was later merged with Intel’s Moblin, another Linux-based operating system, to form MeeGo. Nokia’s Maemo, one of the earliest mobile operating systems, was based on Debian.

Both the Java mailboxd and MariaDB/MySQL processes that are part of the mailbox service benefit from more memory, with a few caveats. In a new install, ZCS tries to allocate 30% of system memory to the Java heap, and 25% of system memory to innodb buffer pool. Please make sure that you do not configure these values too high for your system. Allocation of memory to these two processes is done through the local config variable mailboxd_java_heap_size (in ZCS7 and later) mailboxd_java_heap_memory_percent (in ZCS6 and earlier) and the my. If you believe your system has unused RAM, you can allocate this memory to innodb buffer pool, only after you have monitored your system and made sure your system in not swapping. If these values are too high, your system will swap and swapping is extremely detrimental to ZCS performance. Cnf variable innodb_buffer_pool_size (details on both are in the following sections). Check the JVM Options section to see if you should reduce your heap memory percent.

I suggest updating and testing for yourself to see if you are worried about this attack vector. Again, if you are running a distro kernel, you might be covered as some of the distros have merged various patches into them that they claim mitigate most of the problems here.

This article is the first of  a set supporting the conclusion that the GPL family of copy left licences are the best ones for maintaining a healthy development pace while providing a framework for corporations and users to influence the code base.   It is based on an expansion of the thoughts behind the presentation GPL: The Best Business Licence for Corporate Code at the Compliance Summit 2017 in Yokohama.
