+Subject: [PATCH] monitor/hmp: add support for flag argument with value
+
+Adds support for the "-xS" parameter type, where "-x" denotes a flag
+name and the "S" suffix indicates that this flag is supposed to take an
+arbitrary string parameter.
+
+These parameters are always optional, the entry in the qdict will be
+omitted if the flag is not given.

-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] ide: avoid potential deadlock when draining during trim
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The deadlock can happen as follows:
-1. ide_issue_trim is called, and increments the in_flight counter.
-2. ide_issue_trim_cb calls blk_aio_pdiscard.
-3. Somebody else starts draining (e.g. backup to insert the cbw node).
-4. ide_issue_trim_cb is called as the completion callback for
-   blk_aio_pdiscard.
-5. ide_issue_trim_cb issues yet another blk_aio_pdiscard request.
-6. The request is added to the wait queue via blk_wait_while_drained,
-   because draining has been started.
-7. Nobody ever decrements the in_flight counter and draining can't
-   finish. This would be done by ide_trim_bh_cb, which is called after
-   ide_issue_trim_cb has issued its last request, but
-   ide_issue_trim_cb is not called anymore, because it's the
-   completion callback of blk_aio_pdiscard, which waits on draining.
-
-Quoting Hanna Czenczek:
-> The point of 7e5cdb345f was that we need any in-flight count to
-> accompany a set s->bus->dma->aiocb. While blk_aio_pdiscard() is
-> happening, we don’t necessarily need another count. But we do need
-> it while there is no blk_aio_pdiscard().
-> ide_issue_trim_cb() returns in two cases (and, recursively through
-> its callers, leaves s->bus->dma->aiocb set):
-> 1. After calling blk_aio_pdiscard(), which will keep an in-flight
->    count,
-> 2. After calling replay_bh_schedule_event() (i.e.
->    qemu_bh_schedule()), which does not keep an in-flight count.
-
-Thus, even after moving the blk_inc_in_flight to above the
-replay_bh_schedule_event call, the invariant "ide_issue_trim_cb
-returns with an accompanying in-flight count" is still satisfied.
-
-However, the issue 7e5cdb345f fixed for canceling resurfaces, because
-ide_cancel_dma_sync assumes that it just needs to drain once. But now
-the in_flight count is not consistently > 0 during the trim operation.
-So, change it to drain until !s->bus->dma->aiocb, which means that the
-operation finished (s->bus->dma->aiocb is cleared by ide_set_inactive
-via the ide_dma_cb when the end of the transfer is reached).
-
-Discussion here:
-https://lists.nongnu.org/archive/html/qemu-devel/2023-03/msg02506.html

+ id
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+It is possible to specify more than one VNC server on the command line,
+either with an explicit ID or the auto-generated ones à la "default",
+"vnc2", "vnc3", ...
+
+It is not possible to change the password on one of these extra VNC
+displays though. Fix this by adding a "display" parameter to the
+"set_password" and "expire_password" QMP and HMP commands.
+
+For HMP, the display is specified using the "-d" value flag.
+
+For QMP, the schema is updated to explicitly express the supported
+variants of the commands with protocol-discriminated unions.

-Subject: [PATCH] migration/block-dirty-bitmap: fix loading bitmap when there
- is an iothread
-
-The bdrv_create_dirty_bitmap() function (which is also called by
-bdrv_dirty_bitmap_create_successor()) uses bdrv_getlength(bs). This is
-a wrapper around a coroutine, and thus uses bdrv_poll_co(). Polling
-tries to release the AioContext which will trigger an assert() if it
-hasn't been acquired before.
-
-The issue does not happen for migration, because there we are in a
-coroutine already, so the wrapper will just call bdrv_co_getlength()
-directly without polling.

-Subject: [PATCH] Revert "Revert "graph-lock: Disable locking for now""
-
-This reverts commit 3cce22defb4b0e47cf135444e30cc673cff5ebad.
-
-There are still some issues with graph locking, e.g. deadlocks during
-backup canceling [0]. Because the AioContext locks still exist, it
-should be safe to disable locking again.
-
-From the original 80fc5d2600 ("graph-lock: Disable locking for now"):
-
-> We don't currently rely on graph locking yet. It is supposed to replace
-> the AioContext lock eventually to enable multiqueue support, but as long
-> as we still have the AioContext lock, it is sufficient without the graph
-> lock. Once the AioContext lock goes away, the deadlock doesn't exist any
-> more either and this commit can be reverted. (Of course, it can also be
-> reverted while the AioContext lock still exists if the callers have been
-> fixed.)

-
-Commit 813cd616 ("migration: Use migration_transferred_bytes() to

-when taking a snapshot [0]. The reason turns out to be the flushing
-done by migration_transferred_bytes()

-Just use a _noflush version of the relevant function as a workaround
-until upstream fixes the issue. This is inspired by a not-applied
-upstream series [1], but doing the very minimum to avoid the

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-With VNC, a client can send a non-extended VNC_MSG_CLIENT_CUT_TEXT
-message with len=0. In qemu_clipboard_set_data(), the clipboard info
-will be updated setting data to NULL (because g_memdup(data, size)
-returns NULL when size is 0). If the client does not set the
-VNC_ENCODING_CLIPBOARD_EXT feature when setting up the encodings, then
-the 'request' callback for the clipboard peer is not initialized.
-Later, because data is NULL, qemu_clipboard_request() can be reached
-via vdagent_chr_write() and vdagent_clipboard_recv_request() and
-there, the clipboard owner's 'request' callback will be attempted to
-be called, but that is a NULL pointer.
-
-In particular, this can happen when using the KRDC (22.12.3) VNC
-client.
-
-Another scenario leading to the same issue is with two clients (say
-noVNC and KRDC):
-
-The noVNC client sets the extension VNC_FEATURE_CLIPBOARD_EXT and
-initializes its cbpeer.
-
-The KRDC client does not, but triggers a vnc_client_cut_text() (note
-it's not the _ext variant)). There, a new clipboard info with it as
-the 'owner' is created and via qemu_clipboard_set_data() is called,
-which in turn calls qemu_clipboard_update() with that info.
-
-In qemu_clipboard_update(), the notifier for the noVNC client will be
-called, i.e. vnc_clipboard_notify() and also set vs->cbinfo for the
-noVNC client. The 'owner' in that clipboard info is the clipboard peer
-for the KRDC client, which did not initialize the 'request' function.
-That sounds correct to me, it is the owner of that clipboard info.
-
-Then when noVNC sends a VNC_MSG_CLIENT_CUT_TEXT message (it did set
-the VNC_FEATURE_CLIPBOARD_EXT feature correctly, so a check for it
-passes), that clipboard info is passed to qemu_clipboard_request() and
-the original segfault still happens.
-
-Fix the issue by handling updates with size 0 differently. In
-particular, mark in the clipboard info that the type is not available.
-
-While at it, switch to g_memdup2(), because g_memdup() is deprecated.

-Subject: [PATCH] PVE: add IOChannel implementation for savevm-async
-
-based on migration/channel-block.c and the implementation that was
-present in migration/savevm-async.c before QEMU 7.1.
-
-Passes along read/write requests to the given BlockBackend, while
-ensuring that a read request going beyond the end results in a
-graceful short read.
-
-Additionally, allows tracking the current position from the outside
-(intended to be used for progress tracking).

 Subject: [PATCH] PVE-Backup: add vma backup format code
 
-Notes about partial restoring: skipping a certain drive is done via a
-map line of the form skip=drive-scsi0. Since in PVE, most archives are
-compressed and piped to vma for restore, it's not easily possible to
-skip reads.

-Subject: [PATCH] block/backup: move bcs bitmap initialization to job creation
-
-For backing up the state of multiple disks from the same time, a job
-for each disk has to be created. It's convenient if the jobs don't
-have to be started at the same time and if operation of the VM can be
-resumed after job creation. This would lead to a window between job
-creation and running the job, where writes can happen. But no writes
-should happen between setting up the copy-before-write filter and
-setting up the block copy state bitmap, because then new writes would
-just pass through.
-
-Commit 06e0a9c16405c0a4c1eca33cf286cc04c42066a2 moved initalization of
-the bitmap to setting up the copy-before-write filter when sync_mode
-is not MIRROR_SYNC_MODE_BITMAP. Ensure that the bitmap is initialized
-upon job creation for the remaining case too, by moving the
-backup_init_bcs_bitmap call to backup_job_create.

+From: Stefan Reiter <s.reiter@proxmox.com>
+Date: Mon, 29 Jun 2020 11:06:03 +0200
+Subject: [PATCH] PVE-Backup: Add dirty-bitmap tracking for incremental backups
+
+Uses QEMU's existing MIRROR_SYNC_MODE_BITMAP and a dirty-bitmap on top
+of all backed-up drives. This will only execute the data-write callback
+for any changed chunks, the PBS rust code will reuse chunks from the
+previous index for everything it doesn't receive if reuse_index is true.
+
+On error or cancellation, remove all dirty bitmaps to ensure
+consistency.
+
+Add PBS/incremental specific information to query backup info QMP and
+HMP commands.
+
+Only supported for PBS backups.

+Date: Thu, 20 Aug 2020 14:25:00 +0200
+Subject: [PATCH] PVE-Backup: Use a transaction to synchronize job states
+
+By using a JobTxn, we can sync dirty bitmaps only when *all* jobs were
+successful - meaning we don't need to remove them when the backup fails,
+since QEMU's BITMAP_SYNC_MODE_ON_SUCCESS will now handle that for us.
+
+To keep the rate-limiting and IO impact from before, we use a sequential
+transaction, so drives will still be backed up one after the other.

+Subject: [PATCH] PVE-Backup: Don't block on finishing and cleanup
+ create_backup_jobs
+
+proxmox_backup_co_finish is already async, but previously we would wait
+for the coroutine using block_on_coroutine_fn(). Avoid this by
+scheduling pvebackup_co_complete_stream (and thus pvebackup_co_cleanup)
+as a real coroutine when calling from pvebackup_complete_cb. This is ok,
+since complete_stream uses the backup_mutex internally to synchronize,
+and other streams can happily continue writing in the meantime anyway.
+
+To accomodate, backup_mutex is converted to a CoMutex. This means
+converting every user to a coroutine. This is not just useful here, but
+will come in handy once this series[0] is merged, and QMP calls can be
+yield-able coroutines too. Then we can also finally get rid of
+block_on_coroutine_fn.
+
+Cases of aio_context_acquire/release from within what is now a coroutine
+are changed to aio_co_reschedule_self, which works since a running
+coroutine always holds the aio lock for the context it is running in.
+
+job_cancel_sync is called from a BH since it can't be run from a
+coroutine (uses AIO_WAIT_WHILE internally).
+
+Same thing for create_backup_jobs, which is converted to a BH too.
+
+To communicate the finishing state, a new property is introduced to
+query-backup: 'finishing'. A new state is explicitly not used, since
+that would break compatibility with older qemu-server versions.
+
+Also fix create_backup_jobs:
+
+No more weird bool returns, just the standard "errp" format used
+everywhere else too. With this, if backup_job_create fails, the error
+message is actually returned over QMP and can be shown to the user.
+
+To facilitate correct cleanup on such an error, we call
+create_backup_jobs as a bottom half directly from pvebackup_co_prepare.
+This additionally allows us to actually hold the backup_mutex during
+operation.
+
+Also add a job_cancel_sync before job_unref, since a job must be in
+STATUS_NULL to be deleted by unref, which could trigger an assert
+before.

+Date: Tue, 26 Jan 2021 15:45:30 +0100
+Subject: [PATCH] PVE: Use coroutine QMP for backup/cancel_backup
+
+Finally turn backup QMP calls into coroutines, now that it's possible.
+This has the benefit that calls are asynchronous to the main loop, i.e.
+long running operations like connecting to a PBS server will no longer
+hang the VM.
+
+Additionally, it allows us to get rid of block_on_coroutine_fn, which
+was always a hacky workaround.
+
+While we're already spring cleaning, also remove the QmpBackupTask
+struct, since we can now put the 'prepare' function directly into
+qmp_backup and thus no longer need those giant walls of text.
+
+(Note that for our patches to work with 5.2.0 this change is actually
+required, otherwise monitor_get_fd() fails as we're not in a QMP
+coroutine, but one we start ourselves - we could of course set the
+monitor for that coroutine ourselves, but let's just fix it the right
+way instead)

-Subject: [PATCH] Revert "block/rbd: implement bdrv_co_block_status"
-
-During backup, bdrv_co_block_status is called for each block copy
-chunk. When RBD is used, the current implementation with
-rbd_diff_iterate2() using whole_object=true takes about linearly more
-time, depending on the image size. Since there are linearly more
-chunks, the slowdown is quadratic, becoming unacceptable for large
-images (starting somewhere between 500-1000 GiB in my testing).
-
-This reverts commit 0347a8fd4c3faaedf119be04c197804be40a384b as a
-stop-gap measure, until it's clear how to make the implemenation
-more efficient.

-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.

-From: Fiona Ebner <f.ebner@proxmox.com>
-Date: Fri, 5 May 2023 13:39:53 +0200
-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.

+  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.
