Cpqarrayd 2.2

Cpqarrayd 2.2


Cpqarrayd is a daemon to monitor HP (compaq) arraycontrollers. more>>
Cpqarrayd is a daemon to monitor HP (compaq) arraycontrollers. Cpqarrayd project reports any status changes, like failing disks, to the syslog and optionally to a remote host using SNMP traps.
This tool can run on a linux based intel box with a smart array controller from Compaq. It reports status changes in the disks both to the syslog and to a snmp trap host.
The default is to only log to the syslog. You can specify traphosts with the -t parameter at the commandline. Multiple traphosts are allowed. It checks for valid input, but any errors are non-fatal, in fact the traphost is just ignored..
To ensure correct opereration compile it for the same kernel that runs on the machine where you want to use this. At least make sure that the version of the SmartArray driver is the same. Strange things can happen otherwise.
Enhancements:
- This update is mainly a cleanup and it should fix some compile errors on some systems with 2.6.x kernels. A link to the latest version is located on the left sidebar.

openMosix kernel-2.4.26

openMosix kernel-2.4.26


openMosix is a Linux kernel extension for single-system image clustering. more>>
openMosix is a Linux kernel extension for single-system image clustering. This kernel extension turns a network of ordinary computers into a supercomputer for Linux applications.

Once you have installed openMosix, the nodes in the cluster start talking to one another and the cluster adapts itself to the workload.

Processes originating from any one node, if that node is too busy compared to others, can migrate to any other node. openMosix continuously attempts to optimize the resource allocation.

We achieve this with a kernel patch for Linux, creating a reliable, fast and cost-efficient SSI clustering platform that is linearly scalable and adaptive. With openMosix Auto Discovery, a new node can be added while the cluster is running and the cluster will automatically begin to use the new resources.

There is no need to program applications specifically for openMosix. Since all openMosix extensions are inside the kernel, every Linux application automatically and transparently benefits from the distributed computing concept of openMosix.

The cluster behaves much as does a Symmetric Multi-Processor, but this solution scales to well over a thousand nodes which can themselves be SMPs.

The openMosix Community is very active, contributing add-on applications and sharing helpful information with all users. The openMosix Add-Ons and Community page lists these shared applications. And, it is all GPLd.

Cedar Backup 2.13.2

Cedar Backup 2.13.2


Cedar Backup is a Python package that supports backups of files on local and remote hosts. more>>
Cedar Backup is a Python package that supports backups of files on local and remote hosts to CD-R or CD-RW media over a secure network connection. Cedar Backup project also includes extensions that understand how to back up MySQL databases and Subversion repositories, and it can be easily extended to support other data sources, as well.
The package is focused around weekly backups to a single disc, with the expectation that the disc will be changed or overwritten at the beginning of each week. If your hardware is new enough, Cedar Backup can write multisession discs, allowing you to add to a disc in a daily fashion. Directories are backed up using tar and may be compressed using gzip or bzip2.
There are many different backup software implementations out there in the free-and open-source world. Cedar Backup aims to fill a niche: it aims to be a good fit for people who need to back up a limited amount of important data to CD-R or CD-RW on a regular basis.
Cedar Backup isnt for you if you want to back up your MP3 collection every night, or if you want to back up a few hundred machines. However, if you administer a small set machines and you want to run daily incremental backups for things like system configuration, current email, small web sites, or a CVS repository, then Cedar Backup is probably worth your time.
Cedar Backup has been developed on a Debian GNU/Linux system and is currently supported only on Debian and other Linux systems. However, since it is written in portable Python, it should in theory run without too many problems on other UNIX-like systems which have a working version of the cdrecord and mkisofs utilities.
Enhancements:
- Invalid regular expressions in the configuration are now handled better.
- Other minor documentation cleanups were done.

Cache colouring task_struct and kernel stack 2.5.0-0.5

Cache colouring task_struct and kernel stack 2.5.0-0.5


This helps cache-colours both task_struct and kernel stack using a slab allocator for task_struct and initial stack pointer jittering for kernel stack. more>>

Cache colouring task_struct and kernel stack 2.5.0-0.5 is really useful for it is designed to cache-colours both task_struct and kernel stack.

This patch cache-colours both task_struct and kernel stack using a slab allocator for task_struct and initial stack pointer jittering for kernel stack. An extra structure is defined for task_struct allocations as long as a new init task structure.

By using three stack color bits, eight colors will be used for initial stack frame pointer jittering that should be enough for most cache architectures. Care has to be taken in increasing too much STACK_COLOUR_BITS because this can lead to kernel stack overflows, e.g. a STACK_COLOUR_BITS set to 4 with a cache line size of 128 bytes like P4 will result in a maximum jitter of 2048 bytes by leaving only 6 Kb for the kernel stack.

LIDS 2.2.3 RC1 (for kernel 2.6.21)

LIDS 2.2.3 RC1 (for kernel 2.6.21)


LIDS (Linux Intrusion Detection System) is a kernel patch and admin tools which enhances the kernels security. more>>
LIDS (Linux Intrusion Detection System) is a kernel patch and admin tools which enhances the kernels security by implementing Mandatory Access Control (MAC).

When it is in effect, chosen file access, all system network administration operations, any capability use, raw device, memory, and I/O access can be made impossible even for root. You can define which programs can access specific files.

It uses and extends the system capabilities bounding set to control the whole system and adds some network and filesystem security features to the kernel to enhance the security.

You can finely tune the security protections online, hide sensitive processes, receive security alerts through the network, and more. LIDS currently support kernel 2.6, 2.4.

POE::Kernel 0.3502

POE::Kernel 0.3502


POE::Kernel is an event driven threaded application kernel in Perl. more>>
POE::Kernel is an event driven threaded application kernel in Perl.

SYNOPSIS

POE comes with its own event loop, which is based on select() and written entirely in Perl. To use it, simply:

use POE;

POE can adapt itself to work with other event loops and I/O multiplex systems. Currently it adapts to Gtk, Tk, Event.pm, or IO::Poll when one of those modules is used before POE::Kernel.

use Gtk; # Or Tk, Event, or IO::Poll;
use POE;

or

use POE qw(Loop::Gtk);

or

use POE::Kernel { loop => "Gtk" };
use POE::Session;

Methods to manage the process global Kernel instance:

# Retrieve the kernels unique identifier.
$kernel_id = $kernel->ID;

# Run the event loop, only returning when it has no more sessions to
# dispatch events to. Supports two forms.
$poe_kernel->run();
POE::Kernel->run();

FIFO event methods:

# Post an event to an arbitrary session.
$kernel->post( $session, $event, @event_args );

# Post an event back to the current session.
$kernel->yield( $event, @event_args );

# Call an event handler synchronously. Bypasses POEs event queue
# and returns the handlers return value.
$handler_result = $kernel->call( $session, $event, @event_args );

Original alarm and delay methods:

# Post an event which will be delivered at a given Unix epoch time.
# This clears previous timed events with the same state name.
$kernel->alarm( $event, $epoch_time, @event_args );

# Post an additional alarm, leaving existing ones in the queue.
$kernel->alarm_add( $event, $epoch_time, @event_args );

# Post an event which will be delivered after a delay, specified in
# seconds hence. This clears previous timed events with the same
# name.
$kernel->delay( $event, $seconds, @event_args );

# Post an additional delay, leaving existing ones in the queue.
$kernel->delay_add( $event, $seconds, @event_args );

Linux Kernel Spinlock Metering 1.4.11

Linux Kernel Spinlock Metering 1.4.11


Linux Kernel Spinlock Metering is a kernel patch that allows you to build an i386, ia64, Alpha, Sparc64, or mips64 kernel... more>>
The Linux SMP kernel uses spinlocks to protect data structures from concurrent, potentially conflicting accesses. Linux Kernel Spinlock Metering is a kernel patch that allows you to build an i386, ia64, Alpha, Sparc64, or mips64 kernel that can perform simple "metering" (record-keeping) of spinlock usage. Also available is source for an associated new command, lockstat, that is used to instruct the kernel to turn this lock metering on or off, and to retrieve the metering data from the kernel and display it in a human-readable format.

Data displayed includes the number of lock attempts, per-spinlock per-caller, the number of those attempts that were immediately successful vs. those that required the attempting locker to wait for the current lock-holder to release; the mean and max hold-time, and the mean, max, and cumulative wait-time. Whenever possible, the locking caller and the spinlocks are identified by their symbolic names, not by their virtual addresses.

Various patch sets are available. Version 1.1.4 patches the 2.2.14 kernel and reflects a relatively old flavor of Lockmeter. Version 1.4.11 patches the 2.4.16, 2.4.17, 2.5.3, and 2.5.5 kernels, and the previous release v1.4.9 patches various other releases of the 2.4.x kernel. This version 1.4 supports i386, alpha, ia64, mips64, and sparc64. The most recent version 1.5 is available as a patch against the 2.4.18 and various 2.5.x kernels, and it additionally supports mips (32-bit mips). Each is approximately 22 KB in gziped size. (Patches against a few older kernel versions are also available in the old subdirectory.) After applying the appropriate patch, make oldconfig presents a new Kernel lock metering option in the Kernel hacking subsection -- although only if CONFIG_SMP (Symmetric multi-processing support) has been enabled. The spinlock metering code is compiled into the kernel only when this new option is turned on.

Compiling the spinlock metering code into the kernel does not materially affect the kernel size because the additional code is roughly compensated for by the shrinking effect of the normally in-line locking routines now becoming procedure calls. A metering-capable kernel (i.e., with the patch applied, but data collection turned off) is negligibly slower than a non-metering-capable kernel, though a metering-capable kernel does slow when the metering data collection is turned on using the lockstat command (typically 8% for a systime==25% workload). Care has been taken to minimize performance degradation, and further improvements are in progress.

The lockstat command must also be downloaded, compiled, and installed. lockstat is a privileged command that requires root access. It reads and writes to the node /proc/lockmeter to control the kernels metering as follows:

lockstat on enables the kernels metering data collection,
lockstat options displays the collected data, and
lockstat off disables the metering data collection.

Run lockstat with no arguments to see a verbose description of the command arguments and options.

When metering is enabled, count and time data is collected in malloced arrays that are private to each CPU, thereby avoiding costly cacheblock coherency operations that would otherwise be required if all CPUs updated the same count and time fields. The lockstat command accumulates and sorts the per-cpu data at display time.

Lockmetering attempts to provide both "cause" and "effect" information about spinlock usage. The "hold time" metering exposes which spinlocks are being held and for how long, identified by where they are held inside the kernel. The "wait-time" metering exposes the effects of these hold-times when multiple CPUs concurrently contend for the same lock.

Lanshield Watchdog Linux Kernel Patch is for the onboard(97317VUL) watchdog which resets the device every 10 minutes.

BOARD: PENT/CPCI-765/

it was really hard to find the necessary information...

if you want to know how it works look in the code !!

You can compile it as module(which makes no sense) or fixed in the kernel in the userspace you just write to file /dev/watchdog.
