2023-06-19NFS: add superblock sysfs entriesBenjamin Coddington6-1/+90
Create a sysfs directory for each mount that corresponds to the mount's nfs_server struct. As the mount is being constructed, use the name "server-n", but rename it to the "MAJOR:MINOR" of the mount after assigning a device_id. The rename approach allows us to populate the mount's directory with links to the various rpc_client objects during the mount's construction. The naming convention (MAJOR:MINOR) can be used to reference a particular NFS mount's sysfs tree.

2023-06-19NFS: Make all of /sys/fs/nfs network-namespace uniqueBenjamin Coddington2-37/+33
Expand the NFS network-namespaced sysfs from /sys/fs/nfs/net down one level into /sys/fs/nfs by moving the "net" kobject onto struct nfs_netns_client and setting it up during network namespace init. This prepares the way for superblock kobjects within /sys/fs/nfs that will only be visible to matching network namespaces.

2023-06-19NFS: Add an "xprtsec=" NFS mount optionChuck Lever6-15/+102
After some discussion, we decided that controlling transport layer security policy should be separate from the setting for the user authentication flavor. To accomplish this, add a new NFS mount option to select a transport layer security policy for RPC operations associated with the mount point. xprtsec=none - Transport layer security is forced off. xprtsec=tls - Establish an encryption-only TLS session. If the initial handshake fails, the mount fails. If TLS is not available on a reconnect, drop the connection and try again. xprtsec=mtls - Both sides authenticate and an encrypted session is created. If the initial handshake fails, the mount fails. If TLS is not available on a reconnect, drop the connection and try again. To support client peer authentication (mtls), the handshake daemon will have configurable default authentication material (certificate or pre-shared key). In the future, mount options can be added that can provide this material on a per-mount basis. Updates to mount.nfs (to support xprtsec=auto) and nfs(5) will be sent under separate cover.

Use the new TLS handshake API to enable the SunRPC client code to request a TLS handshake. This implements support for RFC 9289, only on TCP sockets.

2023-06-19SUNRPC: Capture CMSG metadata on client-side receiveChuck Lever1-2/+47
kTLS sockets use CMSG to report decryption errors and the need for session re-keying. For RPC-with-TLS, an "application data" message contains a ULP payload, and that is passed along to the RPC client. An "alert" message triggers connection reset. Everything else is discarded.

2023-06-19SUNRPC: Ignore data_ready callbacks during TLS handshakesChuck Lever2-0/+7
The RPC header parser doesn't recognize TLS handshake traffic, so it will close the connection prematurely with an error.

2023-06-19SUNRPC: attempt to reach rpcbind with an abstract socket nameNeilBrown1-8/+31
NFS is primarily name-spaced using network namespaces. However it contacts rpcbind (and gss_proxy) using AF_UNIX sockets which are name-spaced using the mount namespaces. This requires a container using NFSv3 (the form that requires rpcbind) to manage both network and mount namespaces, which can seem an unnecessary burden. As NFS is primarily a network service it makes sense to use network namespaces as much as possible, and to prefer to communicate with an rpcbind running in the same network namespace. This can be done, while preserving the benefits of AF_UNIX sockets, by using an abstract socket address. An abstract address has a nul at the start of sun_path, and a length that is exactly the complete size of the sockaddr_un up to the end of the name, NOT including any trailing nul (which is not part of the address). Abstract addresses are local to a network namespace - regular AF_UNIX path names a resolved in the mount namespace ignoring the network namespace. This patch causes rpcb to first try an abstract address before continuing with regular AF_UNIX and then IP addresses. This ensures backwards compatibility. Choosing the name needs some care as the same address will be configured for rpcbind, and needs to be built in to libtirpc for this enhancement to be fully successful. There is no formal standard for choosing abstract addresses. The defacto standard appears to be to use a path name similar to what would be used for a filesystem AF_UNIX address - but with a leading nul. In that case "\0/var/run/rpcbind.sock" seems like the best choice. However at this time /var/run is deprecated in favour of /run, so "\0/run/rpcbind.sock" might be better. Though as we are deliberately moving away from using the filesystem it might seem more sensible to explicitly break the connection and just have "\0rpcbind.socket" using the same name as the systemd unit file.. This patch chooses the second option, which seems least likely to raise objections. Signed-off-by: NeilBrown <neilb@suse.de> Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
2023-06-19SUNRPC: support abstract unix socket addressesNeilBrown2-4/+13
An "abtract" address for an AF_UNIX socket start with a nul and can contain any bytes for the given length, but traditionally doesn't contain other nuls. When reported, the leading nul is replaced by '@'. sunrpc currently rejects connections to these addresses and reports them as an empty string. To provide support for future use of these addresses, allow them for outgoing connections and report them more usefully.

2023-06-18ata: libata-scsi: Avoid deadlock on rescan after device resumeDamien Le Moal4-4/+25
When an ATA port is resumed from sleep, the port is reset and a power management request issued to libata EH to reset the port and rescanning the device(s) attached to the port. Device rescanning is done by scheduling an ata_scsi_dev_rescan() work, which will execute scsi_rescan_device(). However, scsi_rescan_device() takes the generic device lock, which is also taken by dpm_resume() when the SCSI device is resumed as well. If a device rescan execution starts before the completion of the SCSI device resume, the rcu locking used to refresh the cached VPD pages of the device, combined with the generic device locking from scsi_rescan_device() and from dpm_resume() can cause a deadlock. Avoid this situation by changing struct ata_port scsi_rescan_task to be a delayed work instead of a simple work_struct. ata_scsi_dev_rescan() is modified to check if the SCSI device associated with the ATA device that must be rescanned is not suspended. If the SCSI device is still suspended, ata_scsi_dev_rescan() returns early and reschedule itself for execution after an arbitrary delay of 5ms.

The fix simply adds the initialization, but introduces a #ifdef because there is no spinlock to initialize for the Tiny SRCU used in !SMP builds. Yes, it would be nice to abstract this somehow in order to hide it in SRCU, but I still don't see a good way of doing this" * tag 'urgent-rcu.2023.06.11a' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu: notifier: Initialize new struct srcu_usage field

2023-06-16ALSA: usb-audio: Add quirk flag for HEM devices to enable native DSD playbackLukasz Tyl1-0/+2
This commit adds new DEVICE_FLG with QUIRK_FLAG_DSD_RAW and Vendor Id for HEM devices which supports native DSD. Prior to this change Linux kernel was not enabling native DSD playback for HEM devices, and as a result, DSD audio was being converted to PCM "on the fly". HEM devices, when connected to the system, would only play audio in PCM format, even if the source material was in DSD format. With the addition of new VENDOR_FLG in the quircks.c file, the devices are now correctly recognized, and raw DSD data is transmitted to the device, allowing for native DSD playback.

2023-06-16ALSA: usb-audio: Fix broken resume due to UAC3 power stateTakashi Iwai1-0/+4
As reported in the bugzilla below, the PM resume of a UAC3 device may fail due to the incomplete power state change, stuck at D1. The reason is that the driver expects the full D0 power state change only at hw_params, while the normal PCM resume procedure doesn't call hw_params. For fixing the bug, we add the same power state update to D0 at the prepare callback, which is certainly called by the resume procedure. Note that, with this change, the power state change in the hw_params becomes almost redundant, since snd_usb_hw_params() doesn't touch the parameters (at least it tires so). But dropping it is still a bit risky (e.g. we have the media-driver binding), so I leave the D0 power state change in snd_usb_hw_params() as is for now.

2023-06-16ALSA: seq: oss: Fix racy open/close of MIDI devicesTakashi Iwai1-13/+22
Although snd_seq_oss_midi_open() and snd_seq_oss_midi_close() can be called concurrently from different code paths, we have no proper data protection against races. Introduce open_mutex to each seq_oss_midi object for avoiding the races.
