+The kernel provides the following general purpose memory allocators:

+
+The preferred form for passing a size of a struct is the following:
+

+
+The alternative form where struct name is spelled out hurts readability and
+introduces an opportunity for a bug when the pointer variable type is changed
+but the corresponding sizeof that is passed to a memory allocator is not.

+Casting the return value which is a void pointer is redundant. The conversion
+from void pointer to any other pointer type is guaranteed by the C programming
+language.

+The canonical patch subject line is:
+
+ Subject: [PATCH 001/123] subsystem: summary phrase
+
+The canonical patch message body contains the following:
+
+ - A "from" line specifying the patch author.
+
+ - An empty line.
+
+ - The body of the explanation, which will be copied to the
+ permanent changelog to describe this patch.
+
+ - The "Signed-off-by:" lines, described above, which will
+ also go in the changelog.
+
+ - A marker line containing simply "---".
+
+ - Any additional comments not suitable for the changelog.
+
+ - The actual patch (diff output).
+
+The Subject line format makes it very easy to sort the emails
+alphabetically by subject line - pretty much any email reader will
+support that - since because the sequence number is zero-padded,
+the numerical and alphabetic sort is the same.
+
+The "subsystem" in the email's Subject should identify which
+area or subsystem of the kernel is being patched.
+
+The "summary phrase" in the email's Subject should concisely
+describe the patch which that email contains. The "summary
+phrase" should not be a filename. Do not use the same "summary
+phrase" for every patch in a whole patch series.
+
+Bear in mind that the "summary phrase" of your email becomes
+a globally-unique identifier for that patch. It propagates
+all the way into the git changelog. The "summary phrase" may
+later be used in developer discussions which refer to the patch.
+People will want to google for the "summary phrase" to read
+discussion regarding that patch.
+
+A couple of example Subjects:
+
+ Subject: [patch 2/5] ext2: improve scalability of bitmap searching
+ Subject: [PATCHv2 001/207] x86: fix eflags tracking
+
+The "from" line must be the very first line in the message body,
+and has the form:
+
+ From: Original Author <author@example.com>
+
+The "from" line specifies who will be credited as the author of the
+patch in the permanent changelog. If the "from" line is missing,
+then the "From:" line from the email header will be used to determine
+the patch author in the changelog.
+
+The explanation body will be committed to the permanent source
+changelog, so should make sense to a competent reader who has long
+since forgotten the immediate details of the discussion that might
+have led to this patch.
+
+The "---" marker line serves the essential purpose of marking for patch
+handling tools where the changelog message ends.
+
+One good use for the additional comments after the "---" marker is for
+a diffstat, to show what files have changed, and the number of inserted
+and deleted lines per file. A diffstat is especially useful on bigger
+patches. Other comments relevant only to the moment or the maintainer,
+not suitable for the permanent changelog, should also go here.

+2.6.14 has a new netlink socket implementation, which by default does not

+So, if to use netlink socket (for example using connector)

+
+Where 270 above is SOL_NETLINK, and 1 is a NETLINK_ADD_MEMBERSHIP socket
+option. To drop multicast subscription one should call above socket option
+with NETLINK_DROP_MEMBERSHIP parameter which is defined as 0.
+
+2.6.14 netlink code only allows to select a group which is less or equal to
+the maximum group number, which is used at netlink_kernel_create() time.
+In case of connector it is CN_NETLINK_USERS + 0xf, so if you want to use
+group number 12345, you must increment CN_NETLINK_USERS to that number.
+Additional 0xf numbers are allocated to be used by non-in-kernel users.
+
+Due to this limitation, group 0xffffffff does not work now, so one can
+not use add/remove connector's group notifications, but as far as I know,
+only cn_test.c test module used it.
+
+Some work in netlink area is still being done, so things can be changed in
+2.6.15 timeframe, if it will happen, documentation will be updated for that

+Device-mapper snapshot support
+==============================
+
+Device-mapper allows you, without massive data copying:
+
+*) To create snapshots of any block device i.e. mountable, saved states of
+the block device which are also writable without interfering with the
+original content;
+*) To create device "forks", i.e. multiple different versions of the
+same data stream.
+
+
+In both cases, dm copies only the chunks of data that get changed and
+uses a separate copy-on-write (COW) block device for storage.
+
+
+There are two dm targets available: snapshot and snapshot-origin.
+
+*) snapshot-origin <origin>
+
+which will normally have one or more snapshots based on it.
+You must create the snapshot-origin device before you can create snapshots.
+Reads will be mapped directly to the backing device. For each write, the
+original data will be saved in the <COW device> of each snapshot to keep
+its visible content unchanged, at least until the <COW device> fills up.
+
+
+*) snapshot <origin> <COW device> <persistent?> <chunksize>
+
+A snapshot is created of the <origin> block device. Changed chunks of
+<chunksize> sectors will be stored on the <COW device>. Writes will
+only go to the <COW device>. Reads will come from the <COW device> or
+from <origin> for unchanged data. <COW device> will often be
+smaller than the origin and if it fills up the snapshot will become
+useless and be disabled, returning errors. So it is important to monitor
+the amount of free space and expand the <COW device> before it fills up.
+
+<persistent?> is P (Persistent) or N (Not persistent - will not survive
+after reboot).
+
+
+How this is used by LVM2
+========================
+When you create the first LVM2 snapshot of a volume, four dm devices are used:
+
+1) a device containing the original mapping table of the source volume;
+2) a device used as the <COW device>;
+3) a "snapshot" device, combining #1 and #2, which is the visible snapshot
+ volume;
+4) the "original" volume (which uses the device number used by the original
+ source volume), whose table is replaced by a "snapshot-origin" mapping
+ from device #1.
+
+A fixed naming scheme is used, so with the following commands:
+
+lvcreate -L 1G -n base volumeGroup
+lvcreate -L 100M --snapshot -n snap volumeGroup/base
+
+we'll have this situation (with volumes in above order):

+An ad-hoc collection of notes on IA64 MCA and INIT processing. Feel
+free to update it with notes about any area that is not clear.
+
+---
+
+MCA/INIT are completely asynchronous. They can occur at any time, when
+the OS is in any state. Including when one of the cpus is already
+holding a spinlock. Trying to get any lock from MCA/INIT state is
+asking for deadlock. Also the state of structures that are protected
+by locks is indeterminate, including linked lists.
+
+---
+
+The complicated ia64 MCA process. All of this is mandated by Intel's
+specification for ia64 SAL, error recovery and and unwind, it is not as
+if we have a choice here.
+
+* MCA occurs on one cpu, usually due to a double bit memory error.
+ This is the monarch cpu.
+
+* SAL sends an MCA rendezvous interrupt (which is a normal interrupt)
+ to all the other cpus, the slaves.
+
+* Slave cpus that receive the MCA interrupt call down into SAL, they
+ end up spinning disabled while the MCA is being serviced.
+
+* If any slave cpu was already spinning disabled when the MCA occurred
+ then it cannot service the MCA interrupt. SAL waits ~20 seconds then
+ sends an unmaskable INIT event to the slave cpus that have not
+ already rendezvoused.
+
+* Because MCA/INIT can be delivered at any time, including when the cpu
+ is down in PAL in physical mode, the registers at the time of the
+ event are _completely_ undefined. In particular the MCA/INIT
+ handlers cannot rely on the thread pointer, PAL physical mode can
+ (and does) modify TP. It is allowed to do that as long as it resets
+ TP on return. However MCA/INIT events expose us to these PAL
+ internal TP changes. Hence curr_task().
+
+* If an MCA/INIT event occurs while the kernel was running (not user
+ space) and the kernel has called PAL then the MCA/INIT handler cannot
+ assume that the kernel stack is in a fit state to be used. Mainly
+ because PAL may or may not maintain the stack pointer internally.
+ Because the MCA/INIT handlers cannot trust the kernel stack, they
+ have to use their own, per-cpu stacks. The MCA/INIT stacks are
+ preformatted with just enough task state to let the relevant handlers
+ do their job.
+
+* Unlike most other architectures, the ia64 struct task is embedded in
+ the kernel stack[1]. So switching to a new kernel stack means that
+ we switch to a new task as well. Because various bits of the kernel
+ assume that current points into the struct task, switching to a new
+ stack also means a new value for current.
+
+* Once all slaves have rendezvoused and are spinning disabled, the
+ monarch is entered. The monarch now tries to diagnose the problem
+ and decide if it can recover or not.
+
+* Part of the monarch's job is to look at the state of all the other
+ tasks. The only way to do that on ia64 is to call the unwinder,
+ as mandated by Intel.
+
+* The starting point for the unwind depends on whether a task is
+ running or not. That is, whether it is on a cpu or is blocked. The
+ monarch has to determine whether or not a task is on a cpu before it
+ knows how to start unwinding it. The tasks that received an MCA or
+ INIT event are no longer running, they have been converted to blocked
+ tasks. But (and its a big but), the cpus that received the MCA
+ rendezvous interrupt are still running on their normal kernel stacks!
+
+* To distinguish between these two cases, the monarch must know which
+ tasks are on a cpu and which are not. Hence each slave cpu that
+ switches to an MCA/INIT stack, registers its new stack using
+ set_curr_task(), so the monarch can tell that the _original_ task is
+ no longer running on that cpu. That gives us a decent chance of
+ getting a valid backtrace of the _original_ task.
+
+* MCA/INIT can be nested, to a depth of 2 on any cpu. In the case of a
+ nested error, we want diagnostics on the MCA/INIT handler that
+ failed, not on the task that was originally running. Again this
+ requires set_curr_task() so the MCA/INIT handlers can register their
+ own stack as running on that cpu. Then a recursive error gets a
+ trace of the failing handler's "task".
+
+[1] My (Keith Owens) original design called for ia64 to separate its
+ struct task and the kernel stacks. Then the MCA/INIT data would be
+ chained stacks like i386 interrupt stacks. But that required
+ radical surgery on the rest of ia64, plus extra hard wired TLB
+ entries with its associated performance degradation. David
+ Mosberger vetoed that approach. Which meant that separate kernel
+ stacks meant separate "tasks" for the MCA/INIT handlers.
+
+---
+
+INIT is less complicated than MCA. Pressing the nmi button or using
+the equivalent command on the management console sends INIT to all
+cpus. SAL picks one one of the cpus as the monarch and the rest are
+slaves. All the OS INIT handlers are entered at approximately the same
+time. The OS monarch prints the state of all tasks and returns, after
+which the slaves return and the system resumes.
+
+At least that is what is supposed to happen. Alas there are broken
+versions of SAL out there. Some drive all the cpus as monarchs. Some
+drive them all as slaves. Some drive one cpu as monarch, wait for that
+cpu to return from the OS then drive the rest as slaves. Some versions
+of SAL cannot even cope with returning from the OS, they spin inside
+SAL on resume. The OS INIT code has workarounds for some of these
+broken SAL symptoms, but some simply cannot be fixed from the OS side.
+
+---
+
+The scheduler hooks used by ia64 (curr_task, set_curr_task) are layer
+violations. Unfortunately MCA/INIT start off as massive layer
+violations (can occur at _any_ time) and they build from there.
+
+At least ia64 makes an attempt at recovering from hardware errors, but
+it is a difficult problem because of the asynchronous nature of these
+errors. When processing an unmaskable interrupt we sometimes need
+special code to cope with our inability to take any locks.
+
+---
+
+How is ia64 MCA/INIT different from x86 NMI?
+
+* x86 NMI typically gets delivered to one cpu. MCA/INIT gets sent to
+ all cpus.
+
+* x86 NMI cannot be nested. MCA/INIT can be nested, to a depth of 2
+ per cpu.
+
+* x86 has a separate struct task which points to one of multiple kernel
+ stacks. ia64 has the struct task embedded in the single kernel
+ stack, so switching stack means switching task.
+
+* x86 does not call the BIOS so the NMI handler does not have to worry
+ about any registers having changed. MCA/INIT can occur while the cpu
+ is in PAL in physical mode, with undefined registers and an undefined
+ kernel stack.
+
+* i386 backtrace is not very sensitive to whether a process is running
+ or not. ia64 unwind is very, very sensitive to whether a process is
+ running or not.
+
+---
+
+What happens when MCA/INIT is delivered what a cpu is running user
+space code?
+
+The user mode registers are stored in the RSE area of the MCA/INIT on
+entry to the OS and are restored from there on return to SAL, so user
+mode registers are preserved across a recoverable MCA/INIT. Since the
+OS has no idea what unwind data is available for the user space stack,
+MCA/INIT never tries to backtrace user space. Which means that the OS
+does not bother making the user space process look like a blocked task,
+i.e. the OS does not copy pt_regs and switch_stack to the user space
+stack. Also the OS has no idea how big the user space RSE and memory
+stacks are, which makes it too risky to copy the saved state to a user
+mode stack.
+
+---
+
+How do we get a backtrace on the tasks that were running when MCA/INIT
+was delivered?
+
+mca.c:::ia64_mca_modify_original_stack(). That identifies and
+verifies the original kernel stack, copies the dirty registers from
+the MCA/INIT stack's RSE to the original stack's RSE, copies the
+skeleton struct pt_regs and switch_stack to the original stack, fills
+in the skeleton structures from the PAL minstate area and updates the
+original stack's thread.ksp. That makes the original stack look
+exactly like any other blocked task, i.e. it now appears to be
+sleeping. To get a backtrace, just start with thread.ksp for the
+original task and unwind like any other sleeping task.
+
+---
+
+How do we identify the tasks that were running when MCA/INIT was
+delivered?
+
+If the previous task has been verified and converted to a blocked
+state, then sos->prev_task on the MCA/INIT stack is updated to point to
+the previous task. You can look at that field in dumps or debuggers.
+To help distinguish between the handler and the original tasks,
+handlers have _TIF_MCA_INIT set in thread_info.flags.
+
+The sos data is always in the MCA/INIT handler stack, at offset
+MCA_SOS_OFFSET. You can get that value from mca_asm.h or calculate it
+as KERNEL_STACK_SIZE - sizeof(struct pt_regs) - sizeof(struct
+ia64_sal_os_state), with 16 byte alignment for all structures.
+
+Also the comm field of the MCA/INIT task is modified to include the pid
+of the original task, for humans to use. For example, a comm field of
+'MCA 12159' means that pid 12159 was running when the MCA was
+delivered.

+ ===================
+ KEY REQUEST SERVICE
+ ===================
+
+The key request service is part of the key retention service (refer to
+Documentation/keys.txt). This document explains more fully how that the
+requesting algorithm works.
+
+The process starts by either the kernel requesting a service by calling
+request_key():
+
+ struct key *request_key(const struct key_type *type,
+ const char *description,
+ const char *callout_string);
+
+Or by userspace invoking the request_key system call:
+
+ key_serial_t request_key(const char *type,
+ const char *description,
+ const char *callout_info,
+ key_serial_t dest_keyring);
+
+The main difference between the two access points is that the in-kernel
+interface does not need to link the key to a keyring to prevent it from being
+immediately destroyed. The kernel interface returns a pointer directly to the
+key, and it's up to the caller to destroy the key.
+
+The userspace interface links the key to a keyring associated with the process
+to prevent the key from going away, and returns the serial number of the key to
+the caller.
+
+
+===========
+THE PROCESS
+===========
+
+A request proceeds in the following manner:
+
+ (1) Process A calls request_key() [the userspace syscall calls the kernel
+ interface].
+
+ (2) request_key() searches the process's subscribed keyrings to see if there's
+ a suitable key there. If there is, it returns the key. If there isn't, and
+ callout_info is not set, an error is returned. Otherwise the process
+ proceeds to the next step.
+
+ (3) request_key() sees that A doesn't have the desired key yet, so it creates
+ two things:
+
+ (a) An uninstantiated key U of requested type and description.
+
+ (b) An authorisation key V that refers to key U and notes that process A
+ is the context in which key U should be instantiated and secured, and
+ from which associated key requests may be satisfied.
+
+ (4) request_key() then forks and executes /sbin/request-key with a new session
+ keyring that contains a link to auth key V.
+
+ (5) /sbin/request-key execs an appropriate program to perform the actual
+ instantiation.
+
+ (6) The program may want to access another key from A's context (say a
+ Kerberos TGT key). It just requests the appropriate key, and the keyring
+ search notes that the session keyring has auth key V in its bottom level.
+
+ This will permit it to then search the keyrings of process A with the
+ UID, GID, groups and security info of process A as if it was process A,
+ and come up with key W.
+
+ (7) The program then does what it must to get the data with which to
+ instantiate key U, using key W as a reference (perhaps it contacts a
+ Kerberos server using the TGT) and then instantiates key U.
+
+ (8) Upon instantiating key U, auth key V is automatically revoked so that it
+ may not be used again.
+
+ (9) The program then exits 0 and request_key() deletes key V and returns key
+ U to the caller.
+
+This also extends further. If key W (step 5 above) didn't exist, key W would be
+created uninstantiated, another auth key (X) would be created [as per step 3]
+and another copy of /sbin/request-key spawned [as per step 4]; but the context
+specified by auth key X will still be process A, as it was in auth key V.
+
+This is because process A's keyrings can't simply be attached to
+/sbin/request-key at the appropriate places because (a) execve will discard two
+of them, and (b) it requires the same UID/GID/Groups all the way through.
+
+
+======================
+NEGATIVE INSTANTIATION
+======================
+
+Rather than instantiating a key, it is possible for the possessor of an
+authorisation key to negatively instantiate a key that's under construction.
+This is a short duration placeholder that causes any attempt at re-requesting
+the key whilst it exists to fail with error ENOKEY.
+
+This is provided to prevent excessive repeated spawning of /sbin/request-key
+processes for a key that will never be obtainable.
+
+Should the /sbin/request-key process exit anything other than 0 or die on a
+signal, the key under construction will be automatically negatively
+instantiated for a short amount of time.
+
+
+====================
+THE SEARCH ALGORITHM
+====================
+
+A search of any particular keyring proceeds in the following fashion:
+
+ (1) When the key management code searches for a key (keyring_search_aux) it
+ firstly calls key_permission(SEARCH) on the keyring it's starting with,
+ if this denies permission, it doesn't search further.
+
+ (2) It considers all the non-keyring keys within that keyring and, if any key
+ matches the criteria specified, calls key_permission(SEARCH) on it to see
+ if the key is allowed to be found. If it is, that key is returned; if
+ not, the search continues, and the error code is retained if of higher
+ priority than the one currently set.
+
+ (3) It then considers all the keyring-type keys in the keyring it's currently
+ searching. It calls key_permission(SEARCH) on each keyring, and if this
+ grants permission, it recurses, executing steps (2) and (3) on that
+ keyring.
+
+The process stops immediately a valid key is found with permission granted to
+use it. Any error from a previous match attempt is discarded and the key is
+returned.
+
+When search_process_keyrings() is invoked, it performs the following searches
+until one succeeds:
+
+ (1) If extant, the process's thread keyring is searched.
+
+ (2) If extant, the process's process keyring is searched.
+
+ (3) The process's session keyring is searched.
+
+ (4) If the process has a request_key() authorisation key in its session
+ keyring then:
+
+ (a) If extant, the calling process's thread keyring is searched.
+
+ (b) If extant, the calling process's process keyring is searched.
+
+ (c) The calling process's session keyring is searched.
+
+The moment one succeeds, all pending errors are discarded and the found key is
+returned.
+
+Only if all these fail does the whole thing fail with the highest priority
+error. Note that several errors may have come from LSM.
+
+The error priority is:
+
+ EKEYREVOKED > EKEYEXPIRED > ENOKEY
+
+EACCES/EPERM are only returned on a direct search of a specific keyring where
+the basal keyring does not grant Search permission.

Interrupt transfers, like isochronous transfers, are periodic, and happen

-After a transfer completion is called, the URB is automagically resubmitted.

-Interrupt transfers may only send (or receive) the "maxpacket" value for

- bool

- default y
- ---help---
- If you say Y here, you will get support for terminal devices with
- display and keyboard devices. These are called "virtual" because you
- can run several virtual terminals (also called virtual consoles) on
- one physical terminal. This is rather useful, for example one
- virtual terminal can collect system messages and warnings, another
- one can be used for a text-mode user session, and a third could run
- an X session, all in parallel. Switching between virtual terminals
- is done with certain key combinations, usually Alt-<function key>.
-
- The setterm command ("man setterm") can be used to change the
- properties (such as colors or beeping) of a virtual terminal. The
- man page console_codes(4) ("man console_codes") contains the special
- character sequences that can be used to change those properties
- directly. The fonts used on virtual terminals can be changed with
- the setfont ("man setfont") command and the key bindings are defined
- with the loadkeys ("man loadkeys") command.
-
- You need at least one virtual terminal device in order to make use
- of your keyboard and monitor. Therefore, only people configuring an
- embedded system would want to say N here in order to save some
- memory; the only way to log into such a system is then via a serial
- or network connection.
-
- If unsure, say Y, or else you won't be able to do much with your new
- shiny Linux system :-)
-
-config VT_CONSOLE
- bool
- default y
- ---help---
- The system console is the device which receives all kernel messages
- and warnings and which allows logins in single user mode. If you
- answer Y here, a virtual terminal (the device used to interact with
- a physical terminal) can be used as system console. This is the most
- common mode of operations, so you should say Y here unless you want
- the kernel messages be output only to a serial port (in which case
- you should say Y to "Console on serial port", below).
-
- If you do say Y here, by default the currently visible virtual
- terminal (/dev/tty0) will be used as system console. You can change
- that with a kernel command line option such as "console=tty3" which
- would use the third virtual terminal as system console. (Try "man
- bootparam" or see the documentation of your boot loader (lilo or
- loadlin) about how to pass options to the kernel at boot time.)

- If unsure, say Y.

This driver provides support for the IBM Hard Drive Active Protection
System (hdaps), which provides an accelerometer and other misc. data.
- Supported laptops include the IBM ThinkPad T41, T42, T43, and R51.
- The accelerometer data is readable via sysfs.
+ ThinkPads starting with the R50, T41, and X40 are supported. The
+ accelerometer data is readable via sysfs.
- This driver also provides an input class device, allowing the
- laptop to act as a pinball machine-esque mouse. This is off by
- default but enabled via sysfs or the module parameter "mousedev".
+ This driver also provides an absolute input class device, allowing
+ the laptop to act as a pinball machine-esque joystick.
Say Y here if you have an applicable laptop and want to experience
the awesome power of hdaps.

+ *
+ * This driver uses the sungem driver (c) David Miller
+ * (davem@redhat.com) as its basis.
+ *
+ * The cassini chip has a number of features that distinguish it from
+ * the gem chip:
+ * 4 transmit descriptor rings that are used for either QoS (VLAN) or
+ * load balancing (non-VLAN mode)
+ * batching of multiple packets
+ * multiple CPU dispatching
+ * page-based RX descriptor engine with separate completion rings
+ * Gigabit support (GMII and PCS interface)
+ * MIF link up/down detection works
+ *
+ * RX is handled by page sized buffers that are attached as fragments to
+ * the skb. here's what's done:
+ * -- driver allocates pages at a time and keeps reference counts
+ * on them.
+ * -- the upper protocol layers assume that the header is in the skb
+ * itself. as a result, cassini will copy a small amount (64 bytes)
+ * to make them happy.
+ * -- driver appends the rest of the data pages as frags to skbuffs
+ * and increments the reference count
+ * -- on page reclamation, the driver swaps the page with a spare page.
+ * if that page is still in use, it frees its reference to that page,
+ * and allocates a new page for use. otherwise, it just recycles the
+ * the page.
+ *
+ * NOTE: cassini can parse the header. however, it's not worth it
+ * as long as the network stack requires a header copy.
+ *
+ * TX has 4 queues. currently these queues are used in a round-robin
+ * fashion for load balancing. They can also be used for QoS. for that
+ * to work, however, QoS information needs to be exposed down to the driver
+ * level so that subqueues get targetted to particular transmit rings.
+ * alternatively, the queues can be configured via use of the all-purpose
+ * ioctl.
+ *
+ * RX DATA: the rx completion ring has all the info, but the rx desc
+ * ring has all of the data. RX can conceivably come in under multiple
+ * interrupts, but the INT# assignment needs to be set up properly by
+ * the BIOS and conveyed to the driver. PCI BIOSes don't know how to do
+ * that. also, the two descriptor rings are designed to distinguish between
+ * encrypted and non-encrypted packets, but we use them for buffering
+ * instead.
+ *
+ * by default, the selective clear mask is set up to process rx packets.

+ * At this point, the OF driver seems to have a limitation on transfer
+ * sizes of 0xd bytes on reads and 0x5 bytes on writes. I do not know
+ * wether this is just an OF limit due to some temporary buffer size
+ * or if this is an SMU imposed limit. This driver has the same limitation
+ * for now as I use a 0x10 bytes temporary buffer as well
+ *
+ * Once that is completed, a response is expected from the SMU. This is
+ * obtained via a command of type 0x9a with a length of 1 byte containing
+ * 0 as the data byte. OF also fills the rest of the data buffer with 0xff's
+ * though I can't tell yet if this is actually necessary. Once this command
+ * is complete, at this point, all I can tell is what OF does. OF tests
+ * byte 0 of the reply:
+ * - on read, 0xfe or 0xfc : bus is busy, wait (see below) or nak ?
+ * - on read, 0x00 or 0x01 : reply is in buffer (after the byte 0)
+ * - on write, < 0 -> failure (immediate exit)
+ * - else, OF just exists (without error, weird)
+ *
+ * So on read, there is this wait-for-busy thing when getting a 0xfc or
+ * 0xfe result. OF does a loop of up to 64 retries, waiting 20ms and
+ * doing the above again until either the retries expire or the result
+ * is no longer 0xfe or 0xfc
+ *
+ * The Darwin I2C driver is less subtle though. On any non-success status
+ * from the response command, it waits 5ms and tries again up to 20 times,
+ * it doesn't differenciate between fatal errors or "busy" status.
+ *
+ * This driver provides an asynchronous paramblock based i2c command
+ * interface to be used either directly by low level code or by a higher
+ * level driver interfacing to the linux i2c layer. The current
+ * implementation of this relies on working timers & timer interrupts
+ * though, so be careful of calling context for now. This may be "fixed"
+ * in the future by adding a polling facility.

+ * ki_retry's return value determines when the AIO operation is completed
+ * and an event is generated in the AIO event ring. Except the special
+ * return values described below, the value that is returned from ki_retry
+ * is transferred directly into the completion ring as the operation's
+ * resulting status. Once this has happened ki_retry *MUST NOT* reference
+ * the kiocb pointer again.
+ *
+ * If ki_retry returns -EIOCBQUEUED it has made a promise that aio_complete()
+ * will be called on the kiocb pointer in the future. The AIO core will
+ * not ask the method again -- ki_retry must ensure forward progress.
+ * aio_complete() must be called once and only once in the future, multiple
+ * calls may result in undefined behaviour.
+ *
+ * If ki_retry returns -EIOCBRETRY it has made a promise that kick_iocb()
+ * will be called on the kiocb pointer in the future. This may happen
+ * through generic helpers that associate kiocb->ki_wait with a wait
+ * queue head that ki_retry uses via current->io_wait. It can also happen
+ * with custom tracking and manual calls to kick_iocb(), though that is
+ * discouraged. In either case, kick_iocb() must be called once and only
+ * once. ki_retry must ensure forward progress, the AIO core will wait
+ * indefinitely for kick_iocb() to be called.

+ * ip_conntrack_pptp.c - Version 3.0
+ *
+ * Connection tracking support for PPTP (Point to Point Tunneling Protocol).
+ * PPTP is a a protocol for creating virtual private networks.
+ * It is a specification defined by Microsoft and some vendors
+ * working with Microsoft. PPTP is built on top of a modified
+ * version of the Internet Generic Routing Encapsulation Protocol.
+ * GRE is defined in RFC 1701 and RFC 1702. Documentation of
+ * PPTP can be found in RFC 2637
+ *
+ * (C) 2000-2005 by Harald Welte <laforge@gnumonks.org>
+ *
+ * Development of this code funded by Astaro AG (http://www.astaro.com/)
+ *
+ * Limitations:
+ * - We blindly assume that control connections are always
+ * established in PNS->PAC direction. This is a violation
+ * of RFFC2673
+ * - We can only support one single call within each session
+ *
+ * TODO:
+ * - testing of incoming PPTP calls
+ *
+ * Changes:
+ * 2002-02-05 - Version 1.3
+ * - Call ip_conntrack_unexpect_related() from
+ * pptp_destroy_siblings() to destroy expectations in case
+ * CALL_DISCONNECT_NOTIFY or tcp fin packet was seen
+ * (Philip Craig <philipc@snapgear.com>)
+ * - Add Version information at module loadtime
+ * 2002-02-10 - Version 1.6
+ * - move to C99 style initializers
+ * - remove second expectation if first arrives
+ * 2004-10-22 - Version 2.0
+ * - merge Mandrake's 2.6.x port with recent 2.6.x API changes
+ * - fix lots of linear skb assumptions from Mandrake's port
+ * 2005-06-10 - Version 2.1
+ * - use ip_conntrack_expect_free() instead of kfree() on the
+ * expect's (which are from the slab for quite some time)
+ * 2005-06-10 - Version 3.0
+ * - port helper to post-2.6.11 API changes,
+ * funded by Oxcoda NetBox Blue (http://www.netboxblue.com/)
+ * 2005-07-30 - Version 3.1
+ * - port helper to 2.6.13 API changes
+ *

+ * Connection tracking protocol helper module for GRE.
+ *
+ * GRE is a generic encapsulation protocol, which is generally not very
+ * suited for NAT, as it has no protocol-specific part as port numbers.
+ *
+ * It has an optional key field, which may help us distinguishing two
+ * connections between the same two hosts.
+ *
+ * GRE is defined in RFC 1701 and RFC 1702, as well as RFC 2784
+ *
+ * PPTP is built on top of a modified version of GRE, and has a mandatory
+ * field called "CallID", which serves us for the same purpose as the key
+ * field in plain GRE.
+ *
+ * Documentation about PPTP can be found in RFC 2637

+ * NAT support for PPTP (Point to Point Tunneling Protocol).
+ * PPTP is a a protocol for creating virtual private networks.
+ * It is a specification defined by Microsoft and some vendors
+ * working with Microsoft. PPTP is built on top of a modified
+ * version of the Internet Generic Routing Encapsulation Protocol.
+ * GRE is defined in RFC 1701 and RFC 1702. Documentation of

+ *
+ * (C) 2000-2005 by Harald Welte <laforge@gnumonks.org>
+ *
+ * Development of this code funded by Astaro AG (http://www.astaro.com/)
+ *
+ * TODO: - NAT to a unique tuple, not to TCP source port
+ * (needs netfilter tuple reservation)
+ *
+ * Changes:
+ * 2002-02-10 - Version 1.3
+ * - Use ip_nat_mangle_tcp_packet() because of cloned skb's
+ * in local connections (Philip Craig <philipc@snapgear.com>)
+ * - add checks for magicCookie and pptp version
+ * - make argument list of pptp_{out,in}bound_packet() shorter
+ * - move to C99 style initializers
+ * - print version number at module loadtime
+ * 2003-09-22 - Version 1.5
+ * - use SNATed tcp sourceport as callid, since we get called before
+ * TCP header is mangled (Philip Craig <philipc@snapgear.com>)
+ * 2004-10-22 - Version 2.0
+ * - kernel 2.6.x version
+ * 2005-06-10 - Version 3.0
+ * - kernel >= 2.6.11 version,
+ * funded by Oxcoda NetBox Blue (http://www.netboxblue.com/)

+ * ip_nat_proto_gre.c - Version 2.0
+ *
+ * NAT protocol helper module for GRE.
+ *
+ * GRE is a generic encapsulation protocol, which is generally not very
+ * suited for NAT, as it has no protocol-specific part as port numbers.
+ *
+ * It has an optional key field, which may help us distinguishing two
+ * connections between the same two hosts.
+ *
+ * GRE is defined in RFC 1701 and RFC 1702, as well as RFC 2784
+ *
+ * PPTP is built on top of a modified version of GRE, and has a mandatory
+ * field called "CallID", which serves us for the same purpose as the key
+ * field in plain GRE.
+ *
+ * Documentation about PPTP can be found in RFC 2637
+ *
+ * (C) 2000-2005 by Harald Welte <laforge@gnumonks.org>
+ *
+ * Development of this code funded by Astaro AG (http://www.astaro.com/)
