| | | | | | | | | Yamaha OPL3-SAx chips don't resume properly when playback is running - garbage is played after resume. Restoring the CS4231_PLAYBK_FORMAT register last fixes the problem. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: wss_lib: fix suspend/resumeOndrej Zary2012-07-161-1/+0
| | | | | | | | | | | By setting SNDRV_PCM_INFO_RESUME, wss_lib claims that it can restore the card state fully on resume. But in fact, it can't as DMA is not restored so any playback/capture running during suspend will fail to continue after resume. Remove SNDRV_PCM_INFO_RESUME flag from pcm info field to fix the problem. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

* ALSA: snd-opti9xx: fixes for MED3931 card (opti931)Ondrej Zary2012-06-181-9/+8
| | | | | | | | | | | | | MED3931 card did not work (failed with "OPTI chip not found") because snd-opti9xx gets mc_indir_index from pnp by adding 2 to the pnp-reported port. It probably works for some cards but not for this one. Datasheet says that the port is always at 0xe?e so just force the lowest nibble to be 0xe. Also this card powers up with (ugly) 3D sound enabled. As there's no mixer control for this, just disable it.

This, read-only snapshot can be accessed by userland, concurrently with the live target. Only one metadata snapshot can be held at a time. The pool's status line will give the block location for the current msnap. Since version 0.1.5 of the userland thin provisioning tools, the thin_dump program displays the msnap as follows: thin_dump -m <msnap root> <metadata dev> Available here: https://github.com/jthornber/thin-provisioning-tools Now that userland can access the metadata we can do various things that have traditionally been kernel side tasks: i) Incremental backups. By using metadata snapshots we can work out what blocks have changed over time. Combined with data snapshots we can ensure the data doesn't change while we back it up. A short proof of concept script can be found here: https://github.com/jthornber/thinp-test-suite/blob/master/incremental_backup_example.rb ii) Migration of thin devices from one pool to another. iii) Merging snapshots back into an external origin. iv) Asyncronous replication.

| * dm mpath: allow ioctls to trigger pg initMikulas Patocka2012-06-031-9/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the failure of a group of paths, any alternative paths that need initialising do not become available until further I/O is sent to the device. Until this has happened, ioctls return -EAGAIN. With this patch, new paths are made available in response to an ioctl too. The processing of the ioctl gets delayed until this has happened. Instead of returning an error, we submit a work item to kmultipathd (that will potentially activate the new path) and retry in ten milliseconds. Note that the patch doesn't retry an ioctl if the ioctl itself fails due to a path failure. Such retries should be handled intelligently by the code that generated the ioctl in the first place, noting that some SCSI commands should not be retried because they are not idempotent (XOR write commands). For commands that could be retried, there is a danger that if the device rejected the SCSI command, the path could be errorneously marked as failed, and the request would be retried on another path which might fail too. It can be determined if the failure happens on the device or on the SCSI controller, but there is no guarantee that all SCSI drivers set these flags correctly.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | If I/O needs retrying and only bypassed priority groups are available, set the pg_init_delay_retry flag to wait before retrying. If, for example, the reason for the bypass is that the controller is getting reset or there is a firmware upgrade happening, retrying right away would cause a flood of log messages and retries for what could be a few seconds or even several minutes.

| * | cipso: handle CIPSO options correctly when NetLabel is disabledPaul Moore2012-06-011-1/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When NetLabel is not enabled, e.g. CONFIG_NETLABEL=n, and the system receives a CIPSO tagged packet it is dropped (cipso_v4_validate() returns non-zero). In most cases this is the correct and desired behavior, however, in the case where we are simply forwarding the traffic, e.g. acting as a network bridge, this becomes a problem. This patch fixes the forwarding problem by providing the basic CIPSO validation code directly in ip_options_compile() without the need for the NetLabel or CIPSO code. The new validation code can not perform any of the CIPSO option label/value verification that cipso_v4_validate() does, but it can verify the basic CIPSO option format. The behavior when NetLabel is enabled is unchanged. Signed-off-by: Paul Moore <pmoore@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | We need to validate the number of pages consumed by data_len, otherwise frags array could be overflowed by userspace.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Port is used as an array index before we know if that is proper. For example, in the catas event case, port is zero; however, the port index should lie in the range (1..2). Fix this by using 'port' only in the events where it is of interest. Test for port out of range in the default (unhandled event) case, and do not output a message if it is not an ethernet port.

| * | net/mlx4_core: Fix number of EQs used in ICM initialisationMarcel Apfelbaum2012-06-013-15/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In SRIOV mode, the number of EQs used when computing the total ICM size was incorrect. To fix this, we do the following: 1. We add a new structure to mlx4_dev, mlx4_phys_caps, to contain physical HCA capabilities. The PPF uses the phys capabilities when it computes things like ICM size. The dev_caps structure will then contain the paravirtualized values, making bookkeeping much easier in SRIOV mode. We add a structure rather than a single parameter because there will be other fields in the phys_caps. The first field we add to the mlx4_phys_caps structure is num_phys_eqs. 2. In INIT_HCA, when running in SRIOV mode, the "log_num_eqs" parameter passed to the FW is the number of EQs per VF/PF; each function (PF or VF) has this number of EQs available. However, the total number of EQs which must be allowed for in the ICM is (1 << log_num_eqs) * (#VFs + #PFs). Rather than compute this quantity, we allocate ICM space for 1024 EQs (which is the device maximum number of EQs, and which is the value we place in the mlx4_phys_caps structure). For INIT_HCA, however, we use the per-function number of EQs as described above.
