2006-09-20[S390] zcrypt secure key cryptography extension.Ralph Wuerthner
Allow the user space to send extended cprb messages directly to the PCIXCC / CEX2C cards. This allows the CCA library to construct special crypto requests that use "secure" keys that are stored on the card.

2006-09-20[S390] zcrypt driver Makefile, Kconfig and monolithic build.Martin Schwidefsky
The Makefile and Kconfig changes should be obvious. The monolithic build option is there to create an old-style z90crypt module for backward compatability to older distributions. Signed-off-by: Ralph Wuerthner <rwuerthn@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>

2006-09-20[S390] zcrypt user space interface.Martin Schwidefsky
The user space interface of the zcrypt device driver implements the old user space interface as defined by the old z90crypt driver. Everything is there, the /dev/z90crypt misc character device, all the lovely ioctls and the /proc file. Even writing to the z90crypt proc file to configure the crypto device still works. It stands to reason to remove the proc write function someday since a much cleaner configuration via the sysfs is now available. The ap bus device drivers register crypto cards to the zcrypt user space interface. The request router of the user space interface picks one of the registered cards based on the predicted latency for the request and calls the driver via a callback found in the zcrypt_ops of the device. The request router only knows which operations the card can do and the minimum / maximum number of bits a request can have.

2006-09-20[S390] zcrypt adjunct processor bus.Martin Schwidefsky
Add a bus for the adjunct processor interface. Up to 64 devices can be connect to the ap bus interface, each device with 16 domains. That makes 1024 message queues. The interface is asynchronous, the answer to a message sent to a queue needs to be received at some later point in time. Unfortunately the interface does not provide interrupts when a message reply is pending. So the ap bus needs to implement some fancy polling, each active queue is polled once per 1/HZ second or continuously if an idle cpus exsists and the poll thread is activ (see poll_thread parameter). The ap bus uses the sysfs path /sys/bus/ap and has two bus attributes, ap_domain and config_time. The ap_domain selects one of the 16 domains to be used for this system. This limits the maximum number of ap devices to 64. The config_time attribute contains the number of seconds between two ap bus scans to find new devices. The ap bus uses the modalias entries of the form "ap:tN" to autoload the ap driver for hardware type N. Currently known types are: 3 - PCICC, 4 - PCICA, 5 - PCIXCC, 6 - CEX2A and 7 - CEX2C.

2006-03-24[PATCH] s390: CEX2A crt message lengthEric Rossman
Undetected edge case for CRT messages to CEX2A caused length to be too short, thus truncating the message. The solution was to check a different variable which actually determines which key type is being used. Increment version number in z90main.c to correct level of 1.3.3, fix copyright year and add comment about bitlength limit of CEX2A.

2005-11-09[PATCH] changing CONFIG_LOCALVERSION rebuilds too much, for no good reasonOlaf Hering
This patch removes almost all inclusions of linux/version.h. The 3 #defines are unused in most of the touched files. A few drivers use the simple KERNEL_VERSION(a,b,c) macro, which is unfortunatly in linux/version.h. There are also lots of #ifdef for long obsolete kernels, this was not touched. In a few places, the linux/version.h include was move to where the LINUX_VERSION_CODE was used. quilt vi `find * -type f -name "*.[ch]"|xargs grep -El '(UTS_RELEASE|LINUX_VERSION_CODE|KERNEL_VERSION|linux/version.h)'|grep -Ev '(/(boot|coda|drm)/|~$)'` search pattern: /UTS_RELEASE\|LINUX_VERSION_CODE\|KERNEL_VERSION\|linux\/\(utsname\|version\).h Signed-off-by: Olaf Hering <olh@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
