* pid namespaces: changes to show virtual ids to userPavel Emelyanov2007-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is the largest patch in the set. Make all (I hope) the places where the pid is shown to or get from user operate on the virtual pids. The idea is: - all in-kernel data structures must store either struct pid itself or the pid's global nr, obtained with pid_nr() call; - when seeking the task from kernel code with the stored id one should use find_task_by_pid() call that works with global pids; - when showing pid's numerical value to the user the virtual one should be used, but however when one shows task's pid outside this task's namespace the global one is to be used; - when getting the pid from userspace one need to consider this as the virtual one and use appropriate task/pid-searching functions.

* pid namespaces: define is_global_init() and is_container_init()Serge E. Hallyn2007-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | is_init() is an ambiguous name for the pid==1 check. Split it into is_global_init() and is_container_init(). A cgroup init has it's tsk->pid == 1. A global init also has it's tsk->pid == 1 and it's active pid namespace is the init_pid_ns. But rather than check the active pid namespace, compare the task structure with 'init_pid_ns.child_reaper', which is initialized during boot to the /sbin/init process and never changes. Changelog: 2.6.22-rc4-mm2-pidns1: - Use 'init_pid_ns.child_reaper' to determine if a given task is the global init (/sbin/init) process. This would improve performance and remove dependence on the task_pid(). 2.6.21-mm2-pidns2: - [Sukadev Bhattiprolu] Changed is_container_init() calls in {powerpc, ppc,avr32}/traps.c for the _exception() call to is_global_init(). This way, we kill only the cgroup if the cgroup's init has a bug rather than force a kernel panic.

* pid namespaces: round up the APIPavel Emelianov2007-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | The set of functions process_session, task_session, process_group and task_pgrp is confusing, as the names can be mixed with each other when looking at the code for a long time. The proposals are to * equip the functions that return the integer with _nr suffix to represent that fact, * and to make all functions work with task (not process) by making the common prefix of the same name. For monotony the routines signal_session() and set_signal_session() are replaced with task_session_nr() and set_task_session(), especially since they are only used with the explicit task->signal dereference.

* Console keyboard events and accessibilitySamuel Thibault2007-10-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some blind people use a kernel engine called Speakup which uses hardware synthesis to speak what gets displayed on the screen. They use the PC keyboard to control this engine (start/stop, accelerate, ...) and also need to get keyboard feedback (to make sure to know what they are typing, the caps lock status, etc.) Up to now, the way it was done was very ugly. Below is a patch to add a notifier list for permitting a far better implementation, see ChangeLog above for details. You may wonder why this can't be done at the input layer. The problem is that what people want to monitor is the console keyboard, i.e. all input keyboards that got attached to the console, and with the currently active keymap (i.e. keysyms, not only keycodes). This adds a keyboard notifier that such modules can use to get the keyboard events and possibly eat them, at several stages: - keycodes: even before translation into keysym. - unbound keycodes: when no keysym is bound. - unicode: when the keycode would get translated into a unicode character. - keysym: when the keycode would get translated into a keysym. - post_keysym: after the keysym got interpreted, so as to see the result (caps lock, etc.) This also provides access to k_handler so as to permit simulation of keypresses.

| * x86: Create clflush() inline, remove hardcoded wbinvdH. Peter Anvin2007-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Create an inline function for clflush(), with the proper arguments, and use it instead of hard-coding the instruction. This also removes one instance of hard-coded wbinvd, based on a patch by Bauder de Oliveira Costa.

| * paravirt: refactor struct paravirt_ops into smaller pv_*_opsJeremy Fitzhardinge2007-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch refactors the paravirt_ops structure into groups of functionally related ops: pv_info - random info, rather than function entrypoints pv_init_ops - functions used at boot time (some for module_init too) pv_misc_ops - lazy mode, which didn't fit well anywhere else pv_time_ops - time-related functions pv_cpu_ops - various privileged instruction ops pv_irq_ops - operations for managing interrupt state pv_apic_ops - APIC operations pv_mmu_ops - operations for managing pagetables There are several motivations for this: 1. Some of these ops will be general to all x86, and some will be i386/x86-64 specific. This makes it easier to share common stuff while allowing separate implementations where needed. 2. At the moment we must export all of paravirt_ops, but modules only need selected parts of it. This allows us to export on a case by case basis (and also choose which export license we want to apply). 3. Functional groupings make things a bit more readable. Struct paravirt_ops is now only used as a template to generate patch-site identifiers, and to extract function pointers for inserting into jmp/calls when patching. It is only instantiated when needed.

* | tty: expose new methods needed for drivers to get termios rightAlan Cox2007-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds three new functions (or in one case to be more exact makes it always available) tty_termios_copy_hw Copies all the hardware settings from one termios structure to the other. This is intended for drivers that support little or no hardware setting tty_termios_encode_baud_rate Allows you to set the input and output baud rate in a termios structure. A driver is supposed to set the resulting baud rate from a request so most will want to use this function to set the resulting input and output rates to match the hardware values. Internally it knows about keeping Bxxx encoding when possible to maximise compatibility. tty_encode_baud_rate As above but for the tty's own current termios structure I suspect this will initially need some tweaking as it gets enabled by driver patches over the next few mm cycles so consider this lot -mm only for the moment so it can stabilize and end up neat before it goes to base. I've tried not to break any obscure architectures - if you get a speed you can't represent the code will print warnings on non updated termios systems but not break. Once this is merged and seems sane I've got a growing pile of driver updates to use it - notably for USB serial drivers.

* | add CONFIG_VT_UNICODEBill Nottingham2007-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of now, the kernel defaults to non-unicode and XLATE for the keyboard. We've been changing this in Fedora, but that requires patching the defaults in the kernel. The attached introduces CONFIG_VT_UNICODE, which sets the console in unicode mode by default on boot, including both the virtual terminal and the keyboard driver.
