This is an update of a previous series[1] addressing Johannes' comments, and rebasing on top of linus's master.

[PATCH net 0/5] mptcp: fix signal endpoint readd

by Matthieu Baerts (NGI0)

Issue #501 [1] showed that the Netlink PM currently doesn't correctly support removal and re-add of signal endpoints. Patches 1 and 2 address the issue: the first one in the userspace path- manager, introduced in v5.19 ; and the second one in the in-kernel path- manager, introduced in v5.7. Patch 3 introduces a related selftest. There is no 'Fixes' tag, because it might be hard to backport it automatically, as missing helpers in Bash will not be caught when compiling the kernel or the selftests. The last two patches address two small issues in the MPTCP selftests, one introduced in v6.6., and the other one in v5.17.

[PATCH v2] kselftests: dmabuf-heaps: Ensure the driver name is null-terminated

by Zenghui Yu

Even if a vgem device is configured in, we will skip the import_vgem_fd() test almost every time. TAP version 13 1..11 # Testing heap: system # ======================================= # Testing allocation and importing: ok 1 # SKIP Could not open vgem -1 The problem is that we use the DRM_IOCTL_VERSION ioctl to query the driver version information but leave the name field a non-null-terminated string. Terminate it properly to actually test against the vgem device. While at it, let's check the length of the driver name is exactly 4 bytes and return early otherwise (in case there is a name like "vgemfoo" that gets converted to "vgem\0" unexpectedly).

[PATCH 0/1] Add KUnit tests for llist

by Artur Alves

Hi all, This is part of a hackathon organized by LKCAMP[1], focused on writing tests using KUnit. We reached out a while ago asking for advice on what would be a useful contribution[2] and ended up choosing data structures that did not yet have tests. This patch adds tests for the llist data structure, defined in include/linux/llist.h, and is inspired by the KUnit tests for the doubly linked list in lib/list-test.c[3]. [1] https://lkcamp.dev/about/ [2] https://lore.kernel.org/all/Zktnt7rjKryTh9-N@arch/ [3] https://elixir.bootlin.com/linux/latest/source/lib/list-test.c Artur Alves (1): lib/llist_kunit.c: add KUnit tests for llist lib/Kconfig.debug | 11 ++ lib/Makefile | 1 + lib/llist_kunit.c | 360 ++++++++++++++++++++++++++++++++++++++++++++++ 3 files changed, 372 insertions(+) create mode 100644 lib/llist_kunit.c -- 2.45.2

[PATCH 0/4] Introduce userspace-driven ALSA timers

by Ivan Orlov

There are multiple possible timer sources which could be useful for the sound stream synchronization: hrtimers, hardware clocks (e.g. PTP), timer wheels (jiffies). Currently, using one of them to synchronize the audio stream of snd-aloop module would require writing a kernel-space driver which exports an ALSA timer through the snd_timer interface. However, it is not really convenient for application developers, who may want to define their custom timer sources for audio synchronization. For instance, we could have a network application which receives frames and sends them to snd-aloop pcm device, and another application listening on the other end of snd-aloop. It makes sense to transfer a new period of data only when certain amount of frames is received through the network, but definitely not when a certain amount of jiffies on a local system elapses. Since all of the devices are purely virtual it won't introduce any glitches and will help the application developers to avoid using sample-rate conversion. This patch series introduces userspace-driven ALSA timers: virtual timers which are created and controlled from userspace. The timer can be created from the userspace using the new ioctl SNDRV_TIMER_IOCTL_CREATE. After creating a timer, it becomes available for use system-wide, so it can be passed to snd-aloop as a timer source (timer_source parameter would be "-1.SNDRV_TIMER_GLOBAL_UDRIVEN.{timer_id}"). When the userspace app decides to trigger a timer, it calls another ioctl SNDRV_TIMER_IOCTL_TRIGGER on the file descriptor of a timer. It initiates a transfer of a new period of data. Userspace-driven timers are associated with file descriptors. If the application wishes to destroy the timer, it can simply release the file descriptor of a virtual timer. I believe introducing new ioctl calls is quite inconvenient (as we have a limited amount of them), but other possible ways of app <-> kernel communication (like virtual FS) seem completely inappropriate for this task (but I'd love to discuss alternative solutions). This patch series also updates the snd-aloop module so the global timers can be used as a timer_source for it (it allows using userspace-driven timers as timer source).
