-
-When proxmox-file-restore invokes QEMU, the PID file is a (temporary)
-file that's already unlinked, so resolving the absolute path here
-failed.
-
-It should not be a critical error when the PID file unlink handler
-can't be registered, because the path can't be resolved for whatever
-reason. If the file is already gone from QEMU's perspective (i.e.
-errno is ENOENT), silently ignore the error. Otherwise, print a
-warning.

+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).

+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.)

+Subject: [PATCH] migration states: workaround snapshot performance regression
+
+Commit 813cd616 ("migration: Use migration_transferred_bytes() to
+calculate rate_limit") introduced a prohibitive performance regression
+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
+regression.

+Subject: [PATCH] ui/clipboard: mark type as not available when there is no
+ data
+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] virtio-scsi: Attach event vq notifier with no_poll
+
+As of commit 38738f7dbbda90fbc161757b7f4be35b52205552 ("virtio-scsi:
+don't waste CPU polling the event virtqueue"), we only attach an io_read
+notifier for the virtio-scsi event virtqueue instead, and no polling
+notifiers.  During operation, the event virtqueue is typically
+non-empty, but none of the buffers are intended to be used immediately.
+Instead, they only get used when certain events occur.  Therefore, it
+makes no sense to continuously poll it when non-empty, because it is
+supposed to be and stay non-empty.
+
+We do this by using virtio_queue_aio_attach_host_notifier_no_poll()
+instead of virtio_queue_aio_attach_host_notifier() for the event
+virtqueue.
+
+Commit 766aa2de0f29b657148e04599320d771c36fd126 ("virtio-scsi: implement
+BlockDevOps->drained_begin()") however has virtio_scsi_drained_end() use
+virtio_queue_aio_attach_host_notifier() for all virtqueues, including
+the event virtqueue.  This can lead to it being polled again, undoing
+the benefit of commit 38738f7dbbda90fbc161757b7f4be35b52205552.
+
+Fix it by using virtio_queue_aio_attach_host_notifier_no_poll() for the
+event virtqueue.

+Subject: [PATCH] virtio: Re-enable notifications after drain
+
+During drain, we do not care about virtqueue notifications, which is why
+we remove the handlers on it.  When removing those handlers, whether vq
+notifications are enabled or not depends on whether we were in polling
+mode or not; if not, they are enabled (by default); if so, they have
+been disabled by the io_poll_start callback.
+
+Because we do not care about those notifications after removing the
+handlers, this is fine.  However, we have to explicitly ensure they are
+enabled when re-attaching the handlers, so we will resume receiving
+notifications.  We do this in virtio_queue_aio_attach_host_notifier*().
+If such a function is called while we are in a polling section,
+attaching the notifiers will then invoke the io_poll_start callback,
+re-disabling notifications.
+
+Because we will always miss virtqueue updates in the drained section, we
+also need to poll the virtqueue once after attaching the notifiers.

 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.

-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.

-From: Stefan Reiter <s.reiter@proxmox.com>
-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)

+From: Fiona Ebner <f.ebner@proxmox.com>
+Date: Thu, 6 Apr 2023 14:59:31 +0200
+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.

-Subject: [PATCH] vma: allow partial restore
-
-Introduce a new map line for skipping a certain drive, 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.
-
-For the reader, a new skip flag for VmaRestoreState is added and the
-target is allowed to be NULL if skip is specified when registering. If
-the skip flag is set, no writes will be made as well as no check for
-duplicate clusters. Therefore, the flag is not set for verify.

-Subject: [PATCH] PVE-Backup: create jobs: correctly cancel in error scenario
-
-The first call to job_cancel_sync() will cancel and free all jobs in
-the transaction, so ensure that it's called only once and get rid of
-the job_unref() that would operate on freed memory.
-
-It's also necessary to NULL backup_state.pbs in the error scenario,
-because a subsequent backup_cancel QMP call (as happens in PVE when
-the backup QMP command fails) would try to call proxmox_backup_abort()
-and run into a segfault.

-Subject: [PATCH] PVE-Backup: ensure jobs in di_list are referenced
-
-Ensures that qmp_backup_cancel doesn't pick a job that's already been
-freed. With unlucky timings it seems possible that:
-1. job_exit -> job_completed -> job_finalize_single starts
-2. pvebackup_co_complete_stream gets spawned in completion callback
-3. job finalize_single finishes -> job's refcount hits zero -> job is
-   freed
-4. qmp_backup_cancel comes in and locks backup_state.backup_mutex
-   before pvebackup_co_complete_stream can remove the job from the
-   di_list
-5. qmp_backup_cancel will pick a job that's already been freed

-Subject: [PATCH] PVE-Backup: avoid segfault issues upon backup-cancel
-
-When canceling a backup in PVE via a signal it's easy to run into a
-situation where the job is already failing when the backup_cancel QMP
-command comes in. With a bit of unlucky timing on top, it can happen
-that job_exit() runs between schedulung of job_cancel_bh() and
-execution of job_cancel_bh(). But job_cancel_sync() does not expect
-that the job is already finalized (in fact, the job might've been
-freed already, but even if it isn't, job_cancel_sync() would try to
-deref job->txn which would be NULL at that point).
-
-It is not possible to simply use the job_cancel() (which is advertised
-as being async but isn't in all cases) in qmp_backup_cancel() for the
-same reason job_cancel_sync() cannot be used. Namely, because it can
-invoke job_finish_sync() (which uses AIO_WAIT_WHILE and thus hangs if
-called from a coroutine). This happens when there's multiple jobs in
-the transaction and job->deferred_to_main_loop is true (is set before
-scheduling job_exit()) or if the job was not started yet.
-
-Fix the issue by selecting the job to cancel in job_cancel_bh() itself
-using the first job that's not completed yet. This is not necessarily
-the first job in the list, because pvebackup_co_complete_stream()
-might not yet have removed a completed job when job_cancel_bh() runs.
-
-An alternative would be to continue using only the first job and
-checking against JOB_STATUS_CONCLUDED or JOB_STATUS_NULL to decide if
-it's still necessary and possible to cancel, but the approach with
-using the first non-completed job seemed more robust.

-Subject: [PATCH] vma: create: support 64KiB-unaligned input images
-
-which fixes backing up templates with such disks in PVE, for example
-efitype=4m EFI disks on a file-based storage (size = 540672).
-
-If there is not enough left to read, blk_co_preadv will return -EIO,
-so limit the size in the last iteration.
-
-For writing, an unaligned end is already handled correctly.
-
-The call to memset is not strictly necessary, because writing also
-checks that it doesn't write data beyond the end of the image. But
-there are two reasons to do it:
-1. It's cleaner that way.
-2. It allows detecting when the final piece is all zeroes, which might
-   not happen if the buffer still contains data from the previous
-   iteration.

-While the bdrv_co_preadv() calls are expected to return 0 on success,

-local_bytes, because the slice with that size was just initialized).
-
-Don't break out of the loop after the branch with qemu_iovec_memset(),

-The branch seems to be difficult to reach in practice, because the

-Subject: [PATCH] PVE Backup: allow passing max-workers performance setting
-
-For query-proxmox-support, add an indication that it's possible to use
-the setting.
-
-For now, the other two BackupPerf settings are not exposed:
-
-* use-copy-range: would need to be implemented by the backup-dump
-block driver first, and in fact, the default for backup was changed,
-because it wasn't as fast for backup in QEMU, see commit
-6a30f663d4c0b3c45a544d541e0c4e214b2473a1.
-
-* max-chunk: enforced to be at least the backup cluster size, which is
-4 MiB for PBS and otherwise maximum of source and target cluster size.
-And block-copy has a maximum buffer size of 1 MiB, so setting a larger
-max-chunk doesn't even have an effect. To make the setting sensibly
-usable the check would need to be removed and optionally the
-block-copy max buffer size would need to be bumped. I tried doing just
-that, and tested different source/target combinations with different
-max-chunk settings, but there were no noticable improvements over the
-default "unlimited" (resulting in 1 MiB for block-copy).

-  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.
