2022-01-26usb: gadget: f_uac2: Support multiple sampling ratesJulian Scheel
A list of sampling rates can be specified via configfs. All enabled sampling rates are sent to the USB host on request. When the host selects a sampling rate, the internal active rate (stored in struct f_uac2) is updated. The gadget no longer supports only one frequency. Therefore USB strings corresponding to the clock sources are renamed from specific Hz value to general names Input clock/Output clock. Config strings with single value stay compatible with the previous version. Multiple samplerates passed as configuration arrays to g_audio module when built for f_uac2.

2022-01-26usb: gadget: f_serial: Ensure gserial disconnected during unbindWesley Cheng
Some UDCs may return an error during pullup disable as part of the unbind path for a USB configuration. This will lead to a scenario where the disable() callback is skipped, whereas the unbind() still occurs. If this happens, the u_serial driver will continue to fail subsequent binds, due to an already existing entry in the ports array. Ensure that gserial_disconnect() is called during the f_serial unbind, so the ports entry is properly cleared.

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull signal/exit/ptrace updates from Eric Biederman: "This set of changes deletes some dead code, makes a lot of cleanups which hopefully make the code easier to follow, and fixes bugs found along the way. The end-game which I have not yet reached yet is for fatal signals that generate coredumps to be short-circuit deliverable from complete_signal, for force_siginfo_to_task not to require changing userspace configured signal delivery state, and for the ptrace stops to always happen in locations where we can guarantee on all architectures that the all of the registers are saved and available on the stack. Removal of profile_task_ext, profile_munmap, and profile_handoff_task are the big successes for dead code removal this round. A bunch of small bug fixes are included, as most of the issues reported were small enough that they would not affect bisection so I simply added the fixes and did not fold the fixes into the changes they were fixing. There was a bug that broke coredumps piped to systemd-coredump. I dropped the change that caused that bug and replaced it entirely with something much more restrained. Unfortunately that required some rebasing. Some successes after this set of changes: There are few enough calls to do_exit to audit in a reasonable amount of time. The lifetime of struct kthread now matches the lifetime of struct task, and the pointer to struct kthread is no longer stored in set_child_tid. The flag SIGNAL_GROUP_COREDUMP is removed. The field group_exit_task is removed. Issues where task->exit_code was examined with signal->group_exit_code should been examined were fixed.

If bInterval is 1, then p_interval is 8000 and p_interval_mil is 8E9, which is too big for a 32-bit value. While the storage is indeed 64-bit, this value is used as the divisor in do_div() which will truncate it into a uint32_t leading to incorrect calculated values. Switch back to keeping the base value in struct snd_uac_chip which fits easily into an int, meaning that the division can be done in two steps with the divisor fitting safely into a uint32_t on both steps.

2021-12-21usb: gadget: f_fs: Clear ffs_eventfd in ffs_data_clear.Vincent Pelletier
ffs_data_clear is indirectly called from both ffs_fs_kill_sb and ffs_ep0_release, so it ends up being called twice when userland closes ep0 and then unmounts f_fs. If userland provided an eventfd along with function's USB descriptors, it ends up calling eventfd_ctx_put as many times, causing a refcount underflow. NULL-ify ffs_eventfd to prevent these extraneous eventfd_ctx_put calls. Also, set epfiles to NULL right after de-allocating it, for readability. For completeness, ffs_data_clear actually ends up being called thrice, the last call being before the whole ffs structure gets freed, so when this specific sequence happens there is a second underflow happening (but not being reported): /sys/kernel/debug/tracing# modprobe usb_f_fs /sys/kernel/debug/tracing# echo ffs_data_clear > set_ftrace_filter /sys/kernel/debug/tracing# echo function > current_tracer /sys/kernel/debug/tracing# echo 1 > tracing_on (setup gadget, run and kill function userland process, teardown gadget) /sys/kernel/debug/tracing# echo 0 > tracing_on /sys/kernel/debug/tracing# cat trace smartcard-openp-436 [000] ..... 1946.208786: ffs_data_clear <-ffs_data_closed smartcard-openp-431 [000] ..... 1946.279147: ffs_data_clear <-ffs_data_closed smartcard-openp-431 [000] .n... 1946.905512: ffs_data_clear <-ffs_data_put Warning output corresponding to above trace: [ 1946.284139] WARNING: CPU: 0 PID: 431 at lib/refcount.c:28 refcount_warn_saturate+0x110/0x15c [ 1946.293094] refcount_t: underflow; use-after-free.

2021-12-13usb: gadget: u_ether: fix race in setting MAC address in setup phaseMarian Postevca
When listening for notifications through netlink of a new interface being registered, sporadically, it is possible for the MAC to be read as zero. The zero MAC address lasts a short period of time and then switches to a valid random MAC address. This causes problems for netd in Android, which assumes that the interface is malfunctioning and will not use it. In the good case we get this log: InterfaceController::getCfg() ifName usb0 hwAddr 92:a8:f0:73:79:5b ipv4Addr 0.0.0.0 flags 0x1002 In the error case we get these logs: InterfaceController::getCfg() ifName usb0 hwAddr 00:00:00:00:00:00 ipv4Addr 0.0.0.0 flags 0x1002 netd : interfaceGetCfg("usb0") netd : interfaceSetCfg() -> ServiceSpecificException (99, "[Cannot assign requested address] : ioctl() failed") The reason for the issue is the order in which the interface is setup, it is first registered through register_netdev() and after the MAC address is set. Fixed by first setting the MAC address of the net_device and after that calling register_netdev().

Unlike the other integral options supported by the MIDI gadget, index is a signed integer and defaults to -1, which means "choose any sound card index". The generic store routine parses input into a u32 which fails to properly read -1 if an attempt is made to set the value to the default. Add a new macro block for signed values to fix this, and use the correct format string for unsigned values.

2021-11-17usb: gadget: f_fs: Use stream_open() for endpoint filesPavankumar Kondeti
Function fs endpoint file operations are synchronized via an interruptible mutex wait. However we see threads that do ep file operations concurrently are getting blocked for the mutex lock in __fdget_pos(). This is an uninterruptible wait and we see hung task warnings and kernel panic if hung_task_panic systcl is enabled if host does not send/receive the data for long time. The reason for threads getting blocked in __fdget_pos() is due to the file position protection introduced by the commit 9c225f2655e3 ("vfs: atomic f_pos accesses as per POSIX"). Since function fs endpoint files does not have the notion of the file position, switch to the stream mode. This will bypass the file position mutex and threads will be blocked in interruptible state for the function fs mutex. It should not affects user space as we are only changing the task state changes the task state from UNINTERRUPTIBLE to INTERRUPTIBLE while waiting for the USB transfers to be finished. However there is a slight change to the O_NONBLOCK behavior. Earlier threads that are using O_NONBLOCK are also getting blocked inside fdget_pos().

EP IN is hard-coded as ASYNC both in f_uac1 and f_uac2 but u_audio sends steady number of audio frames in each USB packet, without any control. This patch adds 'Playback Pitch 1000000' ctl analogous to the existing 'Capture Pitch 1000000' ctl. The calculation of playback req->length in u_audio_iso_complete respects the Playback Pitch ctl value to 1ppm now. Max. value for Playback Pitch is configured by the existing parameter uac2_opts->fb_max, used also for the Capture Pitch. Since the EP IN packet size can be increased by uac2_opts->fb_max now, maxPacketSize for the playback direction is calculated by the same algorithm as for the async capture direction in f_uac2.c:set_ep_max_packet_size.

2021-10-05usb: gadget: uvc: fix multiple opensThomas Haemmerle
Currently, the UVC function is activated when open on the corresponding v4l2 device is called. On another open the activation of the function fails since the deactivation counter in `usb_function_activate` equals 0. However the error is not returned to userspace since the open of the v4l2 device is successful. On a close the function is deactivated (since deactivation counter still equals 0) and the video is disabled in `uvc_v4l2_release`, although the UVC application potentially is streaming. Move activation of UVC function to subscription on UVC_EVENT_SETUP because there we can guarantee for a userspace application utilizing UVC. Block subscription on UVC_EVENT_SETUP while another application already is subscribed to it, indicated by `bool func_connected` in `struct uvc_device`. Extend the `struct uvc_file_handle` with member `bool is_uvc_app_handle` to tag it as the handle used by the userspace UVC application. With this a process is able to check capabilities of the v4l2 device without deactivating the function for the actual UVC application.

2021-09-14usb: gadget: u_audio: EP-OUT bInterval in fback frequencyPavel Hofman
The patch increases the bitshift in feedback frequency calculation with EP-OUT bInterval value. Tests have revealed that Win10 and OSX UAC2 drivers require the feedback frequency to be based on the actual packet interval instead of on the USB2 microframe. Otherwise they ignore the feedback value. Linux snd-usb-audio driver detects the applied bitshift automatically.
