2023-08-11tty: switch count in tty_ldisc_receive_buf() to size_tJiri Slaby (SUSE)
It comes from both paste_selection() and tty_port_default_receive_buf() as unsigned (int and size_t respectively). Switch to size_t to converge to that eventually. Return the count as size_t too (the two callers above expect that). Switch paste_selection()'s type of 'count' too, so that the returned and passed type match.

2023-08-11tty: make counts in tty_port_client_operations hooks size_tJiri Slaby (SUSE)
The counts in tty_port_client_operations hooks' are currently represented by all 'int', 'unsigned int', and 'size_t'. Unify them all to unsigned 'size_t' for clarity. Note that size_t is used already in tty_buffer.c. So, eventually, it is spread for counts everywhere and this is the beginning. So the two changes namely: * ::receive_buf() is called from tty_ldisc_receive_buf(). And that expects values ">= 0" from ::receive_buf(), so switch its rettype to size_t is fine. tty_ldisc_receive_buf() types will be changed separately. * ::lookahead_buf()'s count comes from lookahead_bufs() and is already 'unsigned int'.

2023-08-11Bluetooth: ISO: Notify user space about failed bis connectionsIulia Tanasescu
Some use cases require the user to be informed if BIG synchronization fails. This commit makes it so that even if the BIG sync established event arrives with error status, a new hconn is added for each BIS, and the iso layer is notified about the failed connections. Unsuccesful bis connections will be marked using the HCI_CONN_BIG_SYNC_FAILED flag. From the iso layer, the POLLERR event is triggered on the newly allocated bis sockets, before adding them to the accept list of the parent socket. From user space, a new fd for each failed bis connection will be obtained by calling accept. The user should check for the POLLERR event on the new socket, to determine if the connection was successful or not. The HCI_CONN_BIG_SYNC flag has been added to mark whether the BIG sync has been successfully established. This flag is checked at bis cleanup, so the HCI LE BIG Terminate Sync command is only issued if needed. The BT_SK_BIG_SYNC flag indicates if BIG create sync has been called for a listening socket, to avoid issuing the command everytime a BIGInfo advertising report is received.

Since limited tracking device per condition, this feature is to support tracking multiple devices concurrently. When a pattern monitor detects the device, this feature issues an address monitor for tracking that device. Let pattern monitor can keep monitor new devices. This feature adds an address filter when receiving a LE monitor device event which monitor handle is for a pattern, and the controller started monitoring the device. And this feature also has cancelled the monitor advertisement from address filters when receiving a LE monitor device event when the controller stopped monitoring the device specified by an address and monitor handle.

2023-08-11Bluetooth: ISO: do not emit new LE Create CIS if previous is pendingPauli Virtanen
LE Create CIS command shall not be sent before all CIS Established events from its previous invocation have been processed. Currently it is sent via hci_sync but that only waits for the first event, but there can be multiple. Make it wait for all events, and simplify the CIS creation as follows: Add new flag HCI_CONN_CREATE_CIS, which is set if Create CIS has been sent for the connection but it is not yet completed. Make BT_CONNECT state to mean the connection wants Create CIS. On events after which new Create CIS may need to be sent, send it if possible and some connections need it. These events are: hci_connect_cis, iso_connect_cfm, hci_cs_le_create_cis, hci_le_cis_estabilished_evt. The Create CIS status/completion events shall queue new Create CIS only if at least one of the connections transitions away from BT_CONNECT, so that we don't loop if controller is sending bogus events.

2023-08-11Bluetooth: ISO: Add support for connecting multiple BISesIulia Tanasescu
It is required for some configurations to have multiple BISes as part of the same BIG. Similar to the flow implemented for unicast, DEFER_SETUP will also be used to bind multiple BISes for the same BIG, before starting Periodic Advertising and creating the BIG. The user will have to open a new socket for each BIS. By setting the BT_DEFER_SETUP socket option and calling connect, a new connection will be added for the BIG and advertising handle set by the socket QoS parameters. Since all BISes will be bound for the same BIG and advertising handle, the socket QoS options and base parameters should match for all connections. By calling connect on a socket that does not have the BT_DEFER_SETUP option set, periodic advertising will be started and the BIG will be created, with a BIS for each previously bound connection. Since a BIG cannot be reconfigured with additional BISes after creation, no more connections can be bound for the BIG after the start periodic advertising and create BIG commands have been queued. The bis_cleanup function has also been updated, so that the advertising set and the BIG will not be terminated unless there are no more bound or connected BISes. The HCI_CONN_BIG_CREATED connection flag has been added to indicate that the BIG has been successfully created. This flag is checked at bis_cleanup, so that the BIG is only terminated if the HCI_LE_Create_BIG_Complete has been received. This implementation has been tested on hardware, using the "isotest" tool with an additional command line option, to specify the number of BISes to create as part of the desired BIG: tools/isotest -i hci0 -s 00:00:00:00:00:00 -N 2 -G 1 -T 1 The btmon log shows that a BIG containing 2 BISes has been created: < HCI Command: LE Create Broadcast Isochronous Group (0x08|0x0068) plen 31 Handle: 0x01 Advertising Handle: 0x01 Number of BIS: 2 SDU Interval: 10000 us (0x002710) Maximum SDU size: 40 Maximum Latency: 10 ms (0x000a) RTN: 0x02 PHY: LE 2M (0x02) Packing: Sequential (0x00) Framing: Unframed (0x00) Encryption: 0x00 Broadcast Code: 00000000000000000000000000000000 > HCI Event: Command Status (0x0f) plen 4 LE Create Broadcast Isochronous Group (0x08|0x0068) ncmd 1 Status: Success (0x00) > HCI Event: LE Meta Event (0x3e) plen 23 LE Broadcast Isochronous Group Complete (0x1b) Status: Success (0x00) Handle: 0x01 BIG Synchronization Delay: 1974 us (0x0007b6) Transport Latency: 1974 us (0x0007b6) PHY: LE 2M (0x02) NSE: 3 BN: 1 PTO: 1 IRC: 3 Maximum PDU: 40 ISO Interval: 10.00 msec (0x0008) Connection Handle #0: 10 Connection Handle #1: 11 < HCI Command: LE Setup Isochronous Data Path (0x08|0x006e) plen 13 Handle: 10 Data Path Direction: Input (Host to Controller) (0x00) Data Path: HCI (0x00) Coding Format: Transparent (0x03) Company Codec ID: Ericsson Technology Licensing (0) Vendor Codec ID: 0 Controller Delay: 0 us (0x000000) Codec Configuration Length: 0 Codec Configuration: > HCI Event: Command Complete (0x0e) plen 6 LE Setup Isochronous Data Path (0x08|0x006e) ncmd 1 Status: Success (0x00) Handle: 10 < HCI Command: LE Setup Isochronous Data Path (0x08|0x006e) plen 13 Handle: 11 Data Path Direction: Input (Host to Controller) (0x00) Data Path: HCI (0x00) Coding Format: Transparent (0x03) Company Codec ID: Ericsson Technology Licensing (0) Vendor Codec ID: 0 Controller Delay: 0 us (0x000000) Codec Configuration Length: 0 Codec Configuration: > HCI Event: Command Complete (0x0e) plen 6 LE Setup Isochronous Data Path (0x08|0x006e) ncmd 1 Status: Success (0x00) Handle: 11 < ISO Data TX: Handle 10 flags 0x02 dlen 44 < ISO Data TX: Handle 11 flags 0x02 dlen 44 > HCI Event: Number of Completed Packets (0x13) plen 5 Num handles: 1 Handle: 10 Count: 1 > HCI Event: Number of Completed Packets (0x13) plen 5 Num handles: 1 Handle: 11 Count: 1 Signed-off-by: Iulia Tanasescu <iulia.tanasescu@nxp.com> Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

2023-08-11fs: add infrastructure for multigrain timestampsJeff Layton
The VFS always uses coarse-grained timestamps when updating the ctime and mtime after a change. This has the benefit of allowing filesystems to optimize away a lot metadata updates, down to around 1 per jiffy, even when a file is under heavy writes. Unfortunately, this has always been an issue when we're exporting via NFSv3, which relies on timestamps to validate caches. A lot of changes can happen in a jiffy, so timestamps aren't sufficient to help the client decide to invalidate the cache. Even with NFSv4, a lot of exported filesystems don't properly support a change attribute and are subject to the same problems with timestamp granularity. Other applications have similar issues with timestamps (e.g backup applications). If we were to always use fine-grained timestamps, that would improve the situation, but that becomes rather expensive, as the underlying filesystem would have to log a lot more metadata updates. What we need is a way to only use fine-grained timestamps when they are being actively queried. POSIX generally mandates that when the the mtime changes, the ctime must also change. The kernel always stores normalized ctime values, so only the first 30 bits of the tv_nsec field are ever used. Use the 31st bit of the ctime tv_nsec field to indicate that something has queried the inode for the mtime or ctime. When this flag is set, on the next mtime or ctime update, the kernel will fetch a fine-grained timestamp instead of the usual coarse-grained one. Filesytems can opt into this behavior by setting the FS_MGTIME flag in the fstype. Filesystems that don't set this flag will continue to use coarse-grained timestamps. Later patches will convert individual filesystems to use the new infrastructure.

2023-08-11soundwire: intel_auxdevice: add hybrid IDA-based device_number allocationPierre-Louis Bossart
The IDA-based allocation is useful to simplify debug, but it was also introduced as a prerequisite to deal with the Intel Lunar Lake hardware programming sequences: the wake-ups have to be handled with a system-unique SDI address at the HDaudio controller level. At the time, the restriction introduced by the IDA to 8 devices total seemed perfectly fine, but recently hardware vendors created configurations with more than 8 devices. Add a new allocation strategy to allow for more than 8 devices using information on the type of devices, and only use the IDA-based allocation for devices capable of generating a wake. In theory the information on wake capabilities should come from firmware, but none of the existing ACPI tables provide it. The drivers set the 'wake_capable' property, but this cannot be used reliably: if the driver probe happens *after* the enumeration, then that property is not initialized yet. Trying to modify the device_number on-the-fly proved to be an impossible task generating race conditions left and right. The only reliable work-around to control the enumeration is to add a quirk table. It's ugly but until platform firmware improves, hopefully as a result of MIPI/SDCA stardization, we can expect that quirk table to grow for each new headset or microphone codec.
