This patch series replaces the old non-generic Hardware Random Number Generator support by a fully generic RNG API. This makes it possible to register additional RNGs from modules. With this patch series applied, Laptops with a bcm43xx chip (PowerBook) have a HW RNG available now. Additionally two new RNG drivers are added for the "ixp4xx" and "omap" devices. (Written by Deepak Saxena). This patch series includes the old patches by Deepak Saxena. The old x86-rng driver has beed split. The userspace RNG daemon can later be updated to select the RNG through /sys/class/misc/hw_random/ for convenience. For now it is sufficient to use cat and echo -n on the sysfs attributes.

Add a /proc/<pid>/attr/keycreate entry that stores the appropriate context for newly-created keys. Modify the selinux_key_alloc hook to make use of the new entry. Update the flask headers to include a new "setkeycreate" permission for processes. Update the flask headers to include a new "create" permission for keys. Use the create permission to restrict which SIDs each task can assign to newly-created keys. Add a new parameter to the security hook "security_key_alloc" to indicate whether it is being invoked by the kernel, or from userspace. If it is being invoked by the kernel, the security hook should never fail. Update the documentation to reflect these changes.

Cause key_alloc_serial() to generate key serial numbers randomly rather than in linear sequence. Using an linear sequence permits a covert communication channel to be established, in which one process can communicate with another by creating or not creating new keys within a certain timeframe. The second process can probe for the expected next key serial number and judge its existence by the error returned. This is a problem as the serial number namespace is globally shared between all tasks, regardless of their context.

Cause the keys linked to a keyring to be unlinked from it when revoked and it causes the data attached to a user-defined key to be discarded when revoked. This frees up most of the quota a key occupied at that point, rather than waiting for the key to actually be destroyed.

Add the ability for key creation to overrun the user's quota in some circumstances - notably when a session keyring is created and assigned to a process that didn't previously have one. This means it's still possible to log in, should PAM require the creation of a new session keyring, and fix an overburdened key quota.

Magic sysrq fails to work on many keyboards, particulary most of notebook keyboards. This patch fixes it. The idea is quite simple: Discard the SysRq break code if Alt is still being held down. This way the broken keyboard can send the break code (or the user with a normal keyboard can release the SysRq key) and the kernel waits until the next key is pressed or the Alt key is released.

nmi_create_files() in arch/i386/oprofile/nmi_int.c depends on model->num_counters (number of performance counters) being less than 10. While this is currently the case, it's too clever by half. Other archs aren't quite as clever: they assume 100. I suggest to normalize them all to 1000.

binfmt_flat.c calls set_personality with PER_LINUX as the personality. On the arm architecture this results in the program running in 26bit usermode. PER_LINUX_32BIT should be used instead.

This patch solve a bug triggered by execvp (this function use calloc to store the argument list and gcc 3.4.x align the stack to word, not to dword). This situation aren't related to signal handling and all 2.6.x have the bug. On ColdFire targets we must force the stack to be aligned.
