+    to an 8.1 binary, in cases where the guest kernel enables the feature
+    (e.g. Ubuntu 23.10).
+    While that breaks migration with machine version 8.1 from an unpatched to

-From: Guenter Roeck <linux@roeck-us.net>
-Date: Tue, 28 Feb 2023 09:11:29 -0800
-Subject: [PATCH] scsi: megasas: Internal cdbs have 16-byte length
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Host drivers do not necessarily set cdb_len in megasas io commands.
-With commits 6d1511cea0 ("scsi: Reject commands if the CDB length
-exceeds buf_len") and fe9d8927e2 ("scsi: Add buf_len parameter to
-scsi_req_new()"), this results in failures to boot Linux from affected
-SCSI drives because cdb_len is set to 0 by the host driver.
-Set the cdb length to its actual size to solve the problem.

-Subject: [PATCH] memory: prevent dma-reentracy issues
-
-Add a flag to the DeviceState, when a device is engaged in PIO/MMIO/DMA.
-This flag is set/checked prior to calling a device's MemoryRegion
-handlers, and set when device code initiates DMA.  The purpose of this
-flag is to prevent two types of DMA-based reentrancy issues:
-
-1.) mmio -> dma -> mmio case
-2.) bh -> dma write -> mmio case
-
-These issues have led to problems such as stack-exhaustion and
-use-after-frees.
-
-Summary of the problem from Peter Maydell:

 This only worked if the target supports backing images, so up until now
 only for qcow2, with alloc-track any driver for the target can be used.
 
-If 'auto-remove' is set, alloc-track will automatically detach itself
-once the backing image is removed. It will be replaced by 'file'.
+Replacing the node cannot be done in the
+track_co_change_backing_file() callback, because replacing a node
+cannot happen in a coroutine and requires the block graph lock
+exclusively. Could either become a special option for the stream job,
+or maybe the upcoming blockdev-replace QMP command can be used in the
+future.

-Subject: [PATCH] block/io: accept NULL qiov in bdrv_pad_request
-
-Some operations, e.g. block-stream, perform reads while discarding the
-results (only copy-on-read matters). In this case they will pass NULL as
-the target QEMUIOVector, which will however trip bdrv_pad_request, since
-it wants to extend its passed vector.
-
-Simply check for NULL and do nothing, there's no reason to pad the
-target if it will be discarded anyway.

+Subject: [PATCH] PVE backup: add fleecing option
+
+When a fleecing option is given, it is expected that each device has
+a corresponding "-fleecing" block device already attached, except for
+EFI disk and TPM state, where fleecing is never used.
+
+The following graph was adapted from [0] which also contains more
+details about fleecing.
+
+[guest]
+   |
+   | root
+   v                 file
+[copy-before-write]<------[snapshot-access]
+   |           |
+   | file      | target
+   v           v
+[source] [fleecing]
+
+For fleecing, a copy-before-write filter is inserted on top of the
+source node, as well as a snapshot-access node pointing to the filter
+node which allows to read the consistent state of the image at the
+time it was inserted. New guest writes are passed through the
+copy-before-write filter which will first copy over old data to the
+fleecing image in case that old data is still needed by the
+snapshot-access node.
+
+The backup process will sequentially read from the snapshot access,
+which has a bitmap and knows whether to read from the original image
+or the fleecing image to get the "snapshot" state, i.e. data from the
+source image at the time when the copy-before-write filter was
+inserted. After reading, the copied sections are discarded from the
+fleecing image to reduce space usage.
+
+All of this can be restricted by an initial dirty bitmap to parts of
+the source image that are required for an incremental backup.
+
+For discard to work, it is necessary that the fleecing image does not
+have a larger cluster size than the backup job granularity. Since
+querying that size does not always work, e.g. for RBD with krbd, the
+cluster size will not be reported, a minimum of 4 MiB is used. A job
+with PBS target already has at least this granularity, so it's just
+relevant for other targets. I.e. edge cases where this minimum is not
+enough should be very rare in practice. If ever necessary in the
+future, can still add a passed-in value for the backup QMP command to
+override.
+
+Additionally, the cbw-timeout and on-cbw-error=break-snapshot options
+are set when installing the copy-before-write filter and
+snapshot-access. When an error or timeout occurs, the problematic (and
+each further) snapshot operation will fail and thus cancel the backup
+instead of breaking the guest write.
+
+Note that job_id cannot be inferred from the snapshot-access bs because
+it has no parent, so just pass the one from the original bs.

+Subject: [PATCH] adapt machine version deprecation for Proxmox VE
+
+In commit a35f8577a0 ("include/hw: add macros for deprecation &
+removal of versioned machines"), a new machine version deprecation and
+removal policy was introduced. After only 3 years a machine version
+will be deprecated while being removed after 6 years.
+
+The deprecation is a bit early considering major PVE releases are
+approximately every 2 years. This means that a deprecation warning can
+already happen for a machine version that was introduced during the
+previous major release. This would scare users for no good reason, so
+avoid deprecating machine versions in PVE too early and define a
+baseline of machine versions that will be supported throughout a
+single major PVE release.

-Subject: [PATCH] alloc-track: fix deadlock during drop
-
-by replacing the block node directly after changing the backing file
-instead of rescheduling it.
-
-With changes in QEMU 8.0, calling bdrv_get_info (and bdrv_unref)
-during drop can lead to a deadlock when using iothread (only triggered
-with multiple disks, except during debugging where it also triggered
-with one disk sometimes):
-1. job_unref_locked acquires the AioContext and calls job->driver->free
-2. track_drop gets scheduled
-3. bdrv_graph_wrlock is called and polls which leads to track_drop being
-   called
-4. track_drop acquires the AioContext recursively
-5. bdrv_get_info is a wrapped coroutine (since 8.0) and thus polls for
-   bdrv_co_get_info. This releases the AioContext, but only once! The
-   documentation for the AIO_WAIT_WHILE macro states that the
-   AioContext lock needs to be acquired exactly once, but there does
-   not seem to be a way for track_drop to know if it acquired the lock
-   recursively or not (without adding further hacks).
-6. Because the AioContext is still held by the main thread once, it can't
-   be acquired before entering bdrv_co_get_info in co_schedule_bh_cb
-   which happens in the iothread
-
-When doing the operation in change_backing_file, the AioContext has
-already been acquired by the caller, so the issue with the recursive
-lock goes away.
-
-The comment explaining why delaying the replace is necessary is
-> we need to schedule this for later however, since when this function
-> is called, the blockjob modifying us is probably not done yet and
-> has a blocker on 'bs'
-
-However, there is no check for blockers in bdrv_replace_node. It would
-need to be done by us, the caller, with check_to_replace_node.
-Furthermore, the mirror job also does its call to bdrv_replace_node
-while there is an active blocker (inserted by mirror itself) and they
-use a specialized version to check for blockers instead of
-check_to_replace_node there. Alloc-track could also do something
-similar to check for other blockers, but it should be fine to rely on
-Proxmox VE that no other operation with the blockdev is going on.
-
-Mirror also drains the target before replacing the node, but the
-target can have other users. In case of alloc-track the file child
-should not be accessible by anybody else and so there can't be an
-in-flight operation for the file child when alloc-track is drained.
-
-The rescheduling based on refcounting is a hack and it doesn't seem to
-be necessary anymore. It's not clear what the original issue from the
-comment was. Testing with older builds with track_drop done directly
-without rescheduling also didn't lead to any noticable issue for me.
-
-One issue it might have been is the one fixed by b1e1af394d
-("block/stream: Drain subtree around graph change"), where
-block-stream had a use-after-free if the base node changed at an
-inconvenient time (which alloc-track's auto-drop does).
-
-It's also not possible to just not auto-replace the alloc-track. Not
-replacing it at all leads to other operations like block resize
-hanging, and there is no good way to replace it manually via QMP
-(there is x-blockdev-change, but it is experimental and doesn't
-implement the required operation yet). Also, it's just cleaner in
-general to not leave unnecessary block nodes lying around.

-Subject: [PATCH] migration: for snapshots, hold the BQL during setup callbacks
-
-In spirit, this is a partial revert of commit 9b09503752 ("migration:
-run setup callbacks out of big lock"), but only for the snapshot case.
-
-For snapshots, the bdrv_writev_vmstate() function is used during setup
-(in QIOChannelBlock backing the QEMUFile), but not holding the BQL
-while calling it could lead to an assertion failure. To understand
-how, first note the following:
-
-1. Generated coroutine wrappers for block layer functions spawn the
-coroutine and use AIO_WAIT_WHILE()/aio_poll() to wait for it.
-2. If the host OS switches threads at an inconvenient time, it can
-happen that a bottom half scheduled for the main thread's AioContext
-is executed as part of a vCPU thread's aio_poll().
-
-An example leading to the assertion failure is as follows:
-
-main thread:
-1. A snapshot-save QMP command gets issued.
-2. snapshot_save_job_bh() is scheduled.
-
-vCPU thread:
-3. aio_poll() for the main thread's AioContext is called (e.g. when
-the guest writes to a pflash device, as part of blk_pwrite which is a
-generated coroutine wrapper).
-4. snapshot_save_job_bh() is executed as part of aio_poll().
-3. qemu_savevm_state() is called.
-4. qemu_mutex_unlock_iothread() is called. Now
-qemu_get_current_aio_context() returns 0x0.
-5. bdrv_writev_vmstate() is executed during the usual savevm setup.
-But this function is a generated coroutine wrapper, so it uses
-AIO_WAIT_WHILE. There, the assertion
-assert(qemu_get_current_aio_context() == qemu_get_aio_context());
-will fail.
-
-To fix it, ensure that the BQL is held during setup. To avoid changing
-the behavior for migration too, introduce conditionals for the setup
-callbacks that need the BQL and only take the lock if it's not already
-held.

+Subject: [PATCH] PVE backup: implement backup access setup and teardown API
+ for external providers
+
+For external backup providers, the state of the VM's disk images at
+the time the backup is started is preserved via a snapshot-access
+block node. Old data is moved to the fleecing image when new guest
+writes come in. The snapshot-access block node, as well as the
+associated bitmap in case of incremental backup, will be exported via
+NBD to the external provider. The NBD export will be done by the
+management layer, the missing functionality is setting up and tearing
+down the snapshot-access block nodes, which this patch adds.
+
+It is necessary to also set up fleecing for EFI and TPM disks, so that
+old data can be moved out of the way when a new guest write comes in.
+
+There can only be one regular backup or one active backup access at
+a time, because both require replacing the original block node of the
+drive. Thus the backup state is re-used, and checks are added to
+prohibit regular backup while snapshot access is active and vice
+versa.
+
+The block nodes added by the backup-access-setup QMP call are not
+tracked anywhere else (there is no job they are associated to like for
+regular backup). This requires adding a callback for teardown when
+QEMU exits, i.e. in qemu_cleanup(). Otherwise, there will be an
+assertion failure that the block graph is not empty when QEMU exits
+before the backup-access-teardown QMP command is called.
+
+The code for the qmp_backup_access_setup() was based on the existing
+qmp_backup() routine.
+
+The return value for the setup QMP command contains information about
+the snapshot-access block nodes that can be used by the management
+layer to set up the NBD exports.
+
+There can be one dirty bitmap for each backup target ID for each
+device (which are tracked in the backup_access_bitmaps hash table).
+The QMP user can specify the ID of the bitmap it likes to use. This ID
+is then compared to the current one for the given target and device.
+If they match, the bitmap is re-used (should it still exist on the
+drive, otherwise re-created). If there is a mismatch, the old bitmap
+is removed and a new one is created.
+
+The return value of the QMP command includes information about what
+bitmap action was taken. Similar to what the query-backup QMP command
+returns for regular backup. It also includes the bitmap name and
+associated block node, so the management layer can then set up an NBD
+export with the bitmap.
+
+While the backup access is active, a background bitmap is also
+required. This is necessary to implement bitmap handling according to
+the original reference [0]. In particular:
+
+- in the error case, new writes since the backup access was set up are
+  in the background bitmap. Because of failure, the previously tracked
+  writes from the backup access bitmap are still required too. Thus,
+  the bitmap is merged with the background bitmap to get all new
+  writes since the last backup.
+
+- in the success case, continue tracking for the next incremental
+  backup in the backup access bitmap. New writes since the backup
+  access was set up are in the background bitmap. Because the backup
+  was successfully, clear the backup access bitmap and merge back the
+  background bitmap to get only the new writes.
+
+Since QEMU cannot know if the backup was successful or not (except if
+failure already happens during the setup QMP command), the management
+layer needs to tell it via the teardown QMP command.
+
+The bitmap action is also recorded in the device info now.
+
+The backup-access api keeps track of what bitmap names got used for
+which devices and thus knows when a bitmap went missing. Propagate
+this information to the QMP user with a new 'missing-recreated'
+variant for the taken bitmap action.

+ info
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+In combination with using a throttle filter to enforce IO limits for
+a guest device, knowing the 'file' child of a block device can be
+useful. If the throttle filter is only intended for guest IO, block
+jobs should not also be limited by the throttle filter, so the
+block operations need to be done with the 'file' child of the top
+throttle node as the target. In combination with mirroring, the name
+of that child is not fixed.
+
+Another scenario is when unplugging a guest device after mirroring
+below a top throttle node, where the mirror target is added explicitly
+via blockdev-add. After mirroring, the target becomes the new 'file'
+child of the throttle node. For unplugging, both the top throttle node
+and the mirror target need to be deleted, because only implicitly
+added child nodes are deleted automatically, and the current 'file'
+child of the throttle node was explicitly added (as the mirror
+target).
+
+In other scenarios, it could be useful to follow the backing chain.
+
+Note that iotests 191 and 273 use _filter_img_info, so the 'children'
+information is filtered out there.

+From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
+From: Fiona Ebner <f.ebner@proxmox.com>
+Date: Wed, 18 Jun 2025 12:25:31 +0200
+Subject: [PATCH] savevm-async: reuse migration blocker check for
+ snapshots/hibernation
+
+Same rationale as with upstream QEMU commit 5aaac46793 ("migration:
+savevm: consult migration blockers"), migration and (async) snapshot
+are essentially the same operation and thus snapshot also needs to
+check for migration blockers. For example, this catches passed-through
+PCI devices, where the driver does not support migration and VirtIO-GL
+display, which also does not support migration yet.
+
+In the case of VirtIO-GL, there were crashes [0].
+
+However, the commit notes:
+
+> There is really no difference between live migration and savevm, except
+> that savevm does not require bdrv_invalidate_cache to be implemented
+> by all disks.  However, it is unlikely that savevm is used with anything
+> except qcow2 disks, so the penalty is small and worth the improvement
+> in catching bad usage of savevm.
+
+and for Proxmox VE, suspend-to-disk with VMDK does use savevm-async
+and would be broken by simply using migration_is_blocked(). To keep
+this working, introduce a new helper that filters blockers with the
+prefix used by the VMDK migration blocker.
+
+The function qemu_savevm_state_blocked() is called as part of
+savevm_async_is_blocked() so no check is lost with this
+patch. The helper is declared in migration/migration.c to be able to
+access the 'migration_blockers'.
+
+The VMDK blocker message is declared via a '#define', because using a
+'const char*' led to the linker to complain about multiple
+declarations. The message does not include the reference to the block
+node anymore, but users can still easily find a VMDK disk in the VM
+configuration.
+
+Note, this also "breaks" snapshot and hibernate with VNC clipboard by
+preventing it. Previously, this would "work", because the Proxmox VE
+API has no check yet, but the clipboard will be broken after rollback,
+in the sense that it cannot be used anymore, not just lost contents.
+So some users might consider adding the check here a breaking change
+even if it's technically correct to prevent snapshot and hibernate
+with VNC clipboard. But other users might rightfully complain about
+broken clipboard. And again, the check also prevents blockers from
+passed-through PCI devices, etc. so it seems worth tolerating that
+breakage.

-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-			    Preamble
-
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.)  You can apply it to
-your programs, too.
-
-  When we speak of free software, we are referring to freedom, not
-price.  Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
-
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
-  For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
-
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
-  The precise terms and conditions for copying, distribution and
-modification follow.
-
-		    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
-
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
-
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
-
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
-
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
-
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
-
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
-
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
-
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
-
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
-this License.
-
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
-otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
-
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
-
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
-
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
-be similar in spirit to the present version, but may differ in detail to
-address new problems or concerns.
-
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
-
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
-
-			    NO WARRANTY
-
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-		     END OF TERMS AND CONDITIONS
-
-	    How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License along
-    with this program; if not, write to the Free Software Foundation, Inc.,
-    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.

-argparse is (c) 2006-2009 Steven J. Bethard <steven.bethard@gmail.com>.
-
-The argparse module was contributed to Python as of Python 2.7 and thus
-was licensed under the Python license. Same license applies to all files in
-the argparse package project.
-
-For details about the Python License, please see doc/Python-License.txt.
-
-History
--------
-
-Before (and including) argparse 1.1, the argparse package was licensed under
-Apache License v2.0.
-
-After argparse 1.1, all project files from the argparse project were deleted
-due to license compatibility issues between Apache License 2.0 and GNU GPL v2.
-
-The project repository then had a clean start with some files taken from
-Python 2.7.1, so definitely all files are under Python License now.
