The cca on the crypto adapter has a restriction in the size of the exponent if a key with a modulus bigger than 2048 bit is used. Thus in that case we have to avoid that the crypto device driver thinks the adapter is defect and sets it offline. Therfore a new member for the zcrypt_device struct called max_exp_bit_length is introduced. This will be set the first time the cca returns the error code function not implemented. If this is done with an adapter twice it will return -EINVAL. Signed-off-by:

Definitions for CEX3 card types are changed to support 4096 bit RSA keys. Also new structs for the accelerator mode are needed. Additionaly when checking the length of key parts, the case for bigger (4096 bit) keys is needed. Signed-off-by:

Implemented an asm in the ap bus and made it accessible for the card specific parts of the zcrypt driver. Thus when a cex3a is recognized a check can be performed to dermine whether the card supports 4096 bit RSA keys. Signed-off-by:

Currently the buffer for diagnose data is allocated in the open function of the debugfs file and is released in the close function. This has the drawback that a user (root) can pin that memory by not closing the file. This patch moves the buffer allocation to the read function. The buffer is automatically released after the buffer is copied to userspace. Signed-off-by:

Use register_external_interrupt() instead of register_early_external_interrupt(). The early variant is not necessary since kmalloc works already. Signed-off-by:

Use an early init call to initialize pfault. That way it is possible to use the register_external_interrupt() instead of the early variant. No need to enable pfault any earlier since it has only effect if user space processes are running. Signed-off-by:

Up to now /proc/interrupts only has statistics for external and i/o interrupts but doesn't split up them any further. This patch adds a line for every single interrupt source so that it is possible to easier tell what the machine is/was doing. Part of the output now looks like this; CPU0 CPU2 CPU4 EXT: 3898 4232 2305 I/O: 782 315 245 CLK: 1029 1964 727 [EXT] Clock Comparator IPI: 2868 2267 1577 [EXT] Signal Processor TMR: 0 0 0 [EXT] CPU Timer TAL: 0 0 0 [EXT] Timing Alert PFL: 0 0 0 [EXT] Pseudo Page Fault [...] NMI: 0 1 1 [NMI] Machine Checks Signed-off-by: -

Let local_tick_enable/disable() reprogram the clock comparator so the function names make semantically more sense. Also that way the functions are more symmetric since normally each local_tick_enable() call usually would have a subsequent call to set_clock_comparator() anyway. Signed-off-by:

The saved interrupt mask and the saved control registers are only relevant while single stepping is set up. A secondary kprobe while kprobe single stepping is active may not occur. That makes is safe to remove the save and restore of kprobe_saved_imask / kprobe_save_ctl from save_previous_kprobe and restore_previous_kprobe. Move all single step related code to two functions, enable_singlestep and disable_singlestep. Signed-off-by: -

Remove special case of a kprobe on a breakpoint while a relocated instruction is single stepped. The only instruction that may cause a fault while kprobe single stepping is active is the relocated instruction. There is no kprobe on the instruction slot retrieved with get_insn_slot().

Fix the check for ap interupts to look for facility bits 2 and 65. Make sure that we only register interrupts for aps, if the machine has ap interrupt support. This patch is relevant only for the 2.6.37 stable series. Cc: stable@kernel.org Signed-off-by:

The preferred source address is currently ignored for local routes, which results in all local connections having a src address that is the same as the local dst address. Fix this by respecting the preferred source address when it is provided for local routes. This bug can be demonstrated as follows: # ifconfig dummy0 192.168.0.1 # ip route show table local | grep local.*dummy0 local 192.168.0.1 dev dummy0 proto kernel scope host src 192.168.0.1 # ip route change table local local 192.168.0.1 dev dummy0 \ proto kernel scope host src 127.0.0.1 # ip route show table local | grep local.*dummy0 local 192.168.0.1 dev dummy0 proto kernel scope host src 127.0.0.1 We now establish a local connection and verify the source IP address selection: # nc -l 192.168.0.1 3128 & # nc 192.168.0.1 3128 & # netstat -ant | grep 192.168.0.1:3128.*EST tcp 0 0 192.168.0.1:3128 192.168.0.1:33228 ESTABLISHED tcp 0 0 192.168.0.1:33228 192.168.0.1:3128 ESTABLISHED Signed-off-by:Joel Sing <jsing@google.com> Signed-off-by:
