* RDMA/mlx5: Don't compare mkey tags in DEVX indirect mkeyAharon Landau2022-10-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 13ad1125b941a5f257d9d3ae70485773abd34792 ] According to the ib spec: If the CI supports the Base Memory Management Extensions defined in this specification, the L_Key format must consist of: 24 bit index in the most significant bits of the R_Key, and 8 bit key in the least significant bits of the R_Key Through a successful Allocate L_Key verb invocation, the CI must let the consumer own the key portion of the returned R_Key Therefore, when creating a mkey using DEVX, the consumer is allowed to change the key part. The kernel should compare only the index part of a R_Key to determine equality with another R_Key. Adding capability in order not to break backward compatibility.

* bpf, cgroup: Reject prog_attach_flags array when effective queryPu Lehui2022-10-211-2/+5
| | | | | | | | | | | | | | | | [ Upstream commit 0e426a3ae030a9e891899370229e117158b35de6 ] Attach flags is only valid for attached progs of this layer cgroup, but not for effective progs. For querying with EFFECTIVE flags, exporting attach flags does not make sense. So when effective query, we reject prog_attach_flags array and don't need to populate it. Also we limit attach_flags to output 0 during effective query.

* tun: support not enabling carrier in TUNSETIFFPatrick Rohr2022-09-231-0/+2
| | | | | | | | | | | | | | | | | | | | | | | This change adds support for not enabling carrier during TUNSETIFF interface creation by specifying the IFF_NO_CARRIER flag. Our tests make heavy use of tun interfaces. In some scenarios, the test process creates the interface but another process brings it up after the interface is discovered via netlink notification. In that case, it is not possible to create a tun/tap interface with carrier off without it racing against the bring up. Immediately setting carrier off via TUNSETCARRIER is still too late.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Pull io_uring fixes from Jens Axboe: - A single fix for over-eager retries for networking (Pavel) - Revert the notification slot support for zerocopy sends. It turns out that even after more than a year or development and testing, there's not full agreement on whether just using plain ordered notifications is Good Enough to avoid the complexity of using the notifications slots. Because of that, we decided that it's best left to a future final decision. We can always bring back this feature, but we can't really change it or remove it once we've released 6.0 with it enabled. The reverts leave the usual CQE notifications as the primary interface for knowing when data was sent, and when it was acked.

| * io_uring/net: simplify zerocopy send user APIPavel Begunkov2022-09-011-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Following user feedback, this patch simplifies zerocopy send API. One of the main complaints is that the current API is difficult with the userspace managing notification slots, and then send retries with error handling make it even worse. Instead of keeping notification slots change it to the per-request notifications model, which posts both completion and notification CQEs for each request when any data has been sent, and only one CQE if it fails. All notification CQEs will have IORING_CQE_F_NOTIF set and IORING_CQE_F_MORE in completion CQEs indicates whether to wait a notification or not. IOSQE_CQE_SKIP_SUCCESS is disallowed with zerocopy sends for now. This is less flexible, but greatly simplifies the user API and also the kernel implementation. We reuse notif helpers in this patch, but in the future there won't be need for keeping two requests.

[...] Typical usage of the bpf_lpm_trie_key is that the struct gets embedded into a user defined key for the LPM BPF map, from the selftest example: struct bpf_lpm_trie_key { <-- UAPI exported struct __u32 prefixlen; __u8 data[]; }; struct lpm_key { <-- BPF program defined struct struct bpf_lpm_trie_key trie_key; __u32 data; }; Undo this for BPF until a different solution can be found. It's the only flexible- array member case in the UAPI header. This was discovered in BPF CI after Dave reported that the include/uapi/linux/bpf.h header was out of sync with tools/include/uapi/linux/bpf.h after 94dfc73e7cf4.

This is a must before getting virtqueue indexes (base) for live migration, since the device could modify them after userland gets them. There are individual ways to perform that action for some devices (VHOST_NET_SET_BACKEND, VHOST_VSOCK_SET_RUNNING, ...) but there was no way to perform it for any vhost device (and, in particular, vhost-vdpa). After a successful return of the ioctl call the device must not process more virtqueue descriptors. The device can answer to read or writes of config fields as if it were not suspended. In particular, writing to "queue_enable" with a value of 1 will not make the device start processing buffers of the virtqueue.

The #define CTRL_ATTR_MCAST_GRP_MAX should have stayed right after the previous enum. The new CTRL_ATTR_POLICY_* needs its own define for MAX and that max should not contain the superfluous _DUMP in the name. We probably can't do anything about the CTRL_ATTR_POLICY_DUMP_MAX any more, there's likely code which uses it. For consistency (*cough* codegen *cough*) let's add the correctly name define nonetheless.

Each mailbox is accessed through a DOE Extended Capability. Each DOE mailbox must support the DOE discovery protocol in addition to any number of additional protocols. Define core PCIe functionality to manage a single PCIe DOE mailbox at a defined config space offset. Functionality includes iterating, creating, query of supported protocol, and task submission. Destruction of the mailboxes is device managed.

In this mode, 9th bit is used to indicate an address (byte) within the communication line. ADDRB can only be enabled/disabled through ->rs485_config() that is also responsible for setting the destination and receiver (filter) addresses. Add traps to detect unwanted changes to struct serial_rs485 layout using static_assert().

Instead, I moved this cast outside the ternary to ensure the return type is as expected. Additionally, if __HAVE_BUILTIN_BSWAP16__ was not defined then __swab16 is actually returning an `int` not a `u16` due to integer promotion. As Al Viro notes: You *can't* get smaller-than-int out of ? :, same as you can't get it out of addition, etc. This also fixes some clang -Wformat warnings involving default argument promotion.

Below are some highlights: Core: - Faster lookups of control elements with Xarray; normal user won't notice, but on the devices with tons of control elements, it can be visibly faster - Support for input validation for controls; this will harden for badly written drivers in general with a slight overhead - Deferred async signal handling for working around the potential deadlocks - Cleanup / refactoring raw MIDI locking code ASoC: - Restructing of the set_fmt() callbacks for making things clearer in situations like CODEC to CODEC links - Clean up and modernizing the DAI naming scheme setups - Merge of more of the Intel AVS driver stack, including some board integrations - New version 4 mechanism for communication with SOF DSPs - Suppoort for dynamically selecting the PLL to use at runtime on i.MX platforms - Improvements for CODEC to CODEC support in the generic cards - Support for AMD Jadeite and various machines, AMD RPL, Intel MetorLake DSPs, Mediatek MT8186 DSPs and MT6366, nVidia Tegra MDDRC, OPE and PEQ, NXP TFA9890, Qualcomm SDM845, WCD9335 and WAS883x, and Texas Instruments TAS2780 HD- and USB-audio: - Continued improvement for CS35L41 (sub)codec support - More quirks for various devices (HP, Lenovo, Dell, Clevo)" * tag 'sound-6.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (778 commits) ALSA: hda/realtek: Add quirk for HP Spectre x360 15-eb0xxx ALSA: line6: Replace sprintf() with sysfs_emit() ALSA: hda: Replace sprintf() with sysfs_emit() ALSA: pcm: Replace sprintf() with sysfs_emit() ALSA: core: Replace scnprintf() with sysfs_emit() ALSA: control-led: Replace sprintf() with sysfs_emit() ALSA: aoa: Replace sprintf() with sysfs_emit() ALSA: ac97: Replace sprintf() with sysfs_emit() ALSA: hda/realtek: Add quirk for Clevo NV45PZ ALSA: hda/realtek: Add quirk for Lenovo Yoga9 14IAP7 ALSA: control: Use deferred fasync helper ALSA: pcm: Use deferred fasync helper ALSA: timer: Use deferred fasync helper ALSA: core: Add async signal helpers ASoC: q6asm: use kcalloc() instead of kzalloc() ACPI: scan: Add CLSA0101 Laptop Support ALSA: hda: cs35l41: Support CLSA0101 ALSA: hda: cs35l41: Use the CS35L41 HDA internal define ASoC: dt-bindings: use spi-peripheral-props.yaml ASoC: codecs: va-macro: use fsgen as clock ...
