2023-08-24io_uring: move multishot cqe cache in ctxPavel Begunkov
We cache multishot CQEs before flushing them to the CQ in submit_state.cqe. It's a 16 entry cache totalling 256 bytes in the middle of the io_submit_state structure. Move it out of there, it should help with CPU caches for the submission state, and shouldn't affect cached CQEs.

We also move ->cq_timeouts there because waiters have to read and check it. We can also conditionally hide ->cq_timeouts in the future from the CQ wait path as a not really useful rudiment.

2023-08-24io_uring: add option to remove SQ indirectionPavel Begunkov
Not many aware, but io_uring submission queue has two levels. The first level usually appears as sq_array and stores indexes into the actual SQ. To my knowledge, no one has ever seriously used it, nor liburing exposes it to users. Add IORING_SETUP_NO_SQARRAY, when set we don't bother creating and using the sq_array and SQ heads/tails will be pointing directly into the SQ. Improves memory footprint, in term of both allocations as well as cache usage, and also should make io_get_sqe() less branchy in the end.

2023-08-24io_uring: compact SQ/CQ heads/tailsPavel Begunkov
Queues heads and tails cache line aligned. That makes sq, cq taking 4 lines or 5 lines if we include the rest of struct io_rings (e.g. sq_flags is frequently accessed). Since modern io_uring is mostly single threaded, it doesn't make much send to spread them as such, it wastes space and puts additional pressure on caches. Put them all into a single line.

2023-08-24io_uring: merge iopoll and normal completion pathsPavel Begunkov
io_do_iopoll() and io_submit_flush_completions() are pretty similar, both filling CQEs and then free a list of requests. Don't duplicate it and make iopoll use __io_submit_flush_completions(), which also helps with inlining and other optimisations. For that, we need to first find all completed iopoll requests and splice them from the iopoll list and then pass it down. This adds one extra list traversal, which should be fine as requests will stay hot in cache. CQ locking is already conditional, introduce ->lockless_cq and skip locking for IOPOLL as it's protected by ->uring_lock. We also add a wakeup optimisation for IOPOLL to __io_cq_unlock_post(), so it works just like io_cqring_ev_posted_iopoll().

Don't keep big_cqe bits of req in a union with hash_node, find a separate space for it. It's bit safer, but also if we keep it always initialised, we can get rid of ugly REQ_F_CQE32_INIT handling.

2023-08-24Bluetooth: ISO: Use defer setup to separate PA sync and BIG syncIulia Tanasescu
This commit implements defer setup support for the Broadcast Sink scenario: By setting defer setup on a broadcast socket before calling listen, the user is able to trigger the PA sync and BIG sync procedures separately. This is useful if the user first wants to synchronize to the periodic advertising transmitted by a Broadcast Source, and trigger the BIG sync procedure later on. If defer setup is set, once a PA sync established event arrives, a new hcon is created and notified to the ISO layer. A child socket associated with the PA sync connection will be added to the accept queue of the listening socket. Once the accept call returns the fd for the PA sync child socket, the user should call read on that fd. This will trigger the BIG create sync procedure, and the PA sync socket will become a listening socket itself. When the BIG sync established event is notified to the ISO layer, the bis connections will be added to the accept queue of the PA sync parent. The user should call accept on the PA sync socket to get the final bis connections.

2023-08-24bonding: fix macvlan over alb bond supportHangbin Liu
The commit 14af9963ba1e ("bonding: Support macvlans on top of tlb/rlb mode bonds") aims to enable the use of macvlans on top of rlb bond mode. However, the current rlb bond mode only handles ARP packets to update remote neighbor entries. This causes an issue when a macvlan is on top of the bond, and remote devices send packets to the macvlan using the bond's MAC address as the destination. After delivering the packets to the macvlan, the macvlan will rejects them as the MAC address is incorrect. Consequently, this commit makes macvlan over bond non-functional. To address this problem, one potential solution is to check for the presence of a macvlan port on the bond device using netif_is_macvlan_port(bond->dev) and return NULL in the rlb_arp_xmit() function. However, this approach doesn't fully resolve the situation when a VLAN exists between the bond and macvlan. So let's just do a partial revert for commit 14af9963ba1e in rlb_arp_xmit(). As the comment said, Don't modify or load balance ARPs that do not originate locally.

2023-08-24ALSA: ump: Don't create unused substreams for static blocksTakashi Iwai
When the UMP Endpoint is declared as "static", that is, no dynamic reassignment of UMP Groups, it makes little sense to expose always all 16 groups with 16 substreams. Many of those substreams are disabled groups, hence they are useless, but applications don't know it and try to open / access all those substreams unnecessarily. This patch limits the number of UMP legacy rawmidi substreams only to the active groups. The behavior is changed only for the static endpoint (i.e. devices without UMP v1.1 feature implemented or with the static block flag is set).

2023-08-24drm/nouveau: uapi: don't pass NO_PREFETCH flag implicitlyDanilo Krummrich
Currently, NO_PREFETCH is passed implicitly through drm_nouveau_gem_pushbuf_push::length and drm_nouveau_exec_push::va_len. Since this is a direct representation of how the HW is programmed it isn't really future proof for a uAPI. Hence, fix this up for the new uAPI and split up the va_len field of struct drm_nouveau_exec_push, such that we keep 32bit for va_len and 32bit for flags. For drm_nouveau_gem_pushbuf_push::length at least provide NOUVEAU_GEM_PUSHBUF_NO_PREFETCH to indicate the bit shift. While at it, fix up nv50_dma_push() as well, such that the caller doesn't need to encode the NO_PREFETCH flag into the length parameter.

2023-08-23binfmt_elf_fdpic: support 64-bit systemsGreg Ungerer
The binfmt_flat_fdpic code has a number of 32-bit specific data structures associated with it. Extend it to be able to support and be used on 64-bit systems as well. The new code defines a number of key 64-bit variants of the core elf-fdpic data structures - along side the existing 32-bit sized ones. A common set of generic named structures are defined to be either the 32-bit or 64-bit ones as required at compile time. This is a similar technique to that used in the ELF binfmt loader. For example: elf_fdpic_loadseg is either elf32_fdpic_loadseg or elf64_fdpic_loadseg elf_fdpic_loadmap is either elf32_fdpic_loadmap or elf64_fdpic_loadmap the choice based on ELFCLASS32 or ELFCLASS64.

2023-08-23SUNRPC: kmap() the xdr pages during decodeAnna Schumaker
If the pages are in HIGHMEM then we need to make sure they're mapped before trying to read data off of them, otherwise we could end up with a NULL pointer dereference. The downside to this is that we need an extra cleanup step at the end of decode to kunmap() the last page. I introduced an xdr_finish_decode() function to do this. Right now this function only calls the unmap_current_page() function, but other generic cleanup steps could be added in the future if we come across anything else.

2023-08-23netfilter: nf_tables: defer gc run if previous batch is still pendingFlorian Westphal
Don't queue more gc work, else we may queue the same elements multiple times. If an element is flagged as dead, this can mean that either the previous gc request was invalidated/discarded by a transaction or that the previous request is still pending in the system work queue. The latter will happen if the gc interval is set to a very low value, e.g. 1ms, and system work queue is backlogged. The sets refcount is 1 if no previous gc requeusts are queued, so add a helper for this and skip gc run if old requests are pending. Add a helper for this and skip the gc run in this case.

Add StarFive JH7110(TX0/TX1/RX channels) SoC support in the designware I2S driver and a flag to check if it is on the JH7110 SoC. These channels need to enable clocks, resets and syscon register on the JH7110 SoC. So add init ops in platform data for the JH7110 SoC to do this. Their resets should be deassert before changing the parent of clocks so these are done in the init ops of platform data. The I2S controllers use DMA controller by platform data on the JH7110 and their settings about snd_dmaengine_dai_dma_data() should be added in the dw_configure_dai_by_pd().
