2025-04-14rxrpc: Allow CHALLENGEs to the passed to the app for a RESPONSEDavid Howells
Allow the app to request that CHALLENGEs be passed to it through an out-of-band queue that allows recvmsg() to pick it up so that the app can add data to it with sendmsg(). This will allow the application (AFS or userspace) to interact with the process if it wants to and put values into user-defined fields. This will be used by AFS when talking to a fileserver to supply that fileserver with a crypto key by which callback RPCs can be encrypted (ie. notifications from the fileserver to the client).

2025-04-14net: convert dev->rtnl_link_state to a boolJakub Kicinski
netdevice reg_state was split into two 16 bit enums back in 2010 in commit a2835763e130 ("rtnetlink: handle rtnl_link netlink notifications manually"). Since the split the fields have been moved apart, and last year we converted reg_state to a normal u8 in commit 4d42b37def70 ("net: convert dev->reg_state to u8"). rtnl_link_state being a 16 bitfield makes no sense. Convert it to a single bool, it seems very unlikely after 15 years that we'll need more values in it. We could drop dev->rtnl_link_ops from the conditions but feels like having it there more clearly points at the reason for this hack.

2025-04-14netlink: specs: ovs_vport: align with C codegen capabilitiesJakub Kicinski
We started generating C code for OvS a while back, but actually C codegen only supports fixed headers specified at the family level right now (schema also allows specifying them per op). ovs_flow and ovs_datapath already specify the fixed header at the family level but ovs_vport does it per op. Move the property, all ops use the same header. This ensures YNL C sees the correct hdr_len: const struct ynl_family ynl_ovs_vport_family = { .name = "ovs_vport", - .hdr_len = sizeof(struct genlmsghdr), + .hdr_len = sizeof(struct genlmsghdr) + sizeof(struct ovs_header), }; Fixes: 7c59c9c8f202 ("tools: ynl: generate code for ovs families") Link: https://patch.msgid.link/20250409145541.580674-1-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2025-04-14dt-bindings: interrupt-controller: Add Sophgo SG2044 MSI controllerInochi Amaoto
Like SG2042, SG2044 also uses an external MSI controller to provide MSI interrupt for PCIe controllers. The difference between these two MSI controllers are: 1. SG2044 acks the interrupt by writing 0, SG2042 by setting the bit related to the interrupt. 2. SG2044 uses interrupt number modulo 32 as MSI message data, but SG2042 uses the bit related to the interrupt. Add support for the SG2044 MSI controller.

2025-04-14ASoC: tas27{64,70}: improve support for Apple codecMark Brown
Merge series from James Calligeros <jcalligeros99@gmail.com>: This series introduces a number of changes to the drivers for the Texas Instruments TAS2764 and TAS2770 amplifiers in order to introduce (and improve in the case of TAS2770) support for the variants of these amps found in Apple Silicon Macs. Apple's variant of TAS2764 is known as SN012776, and as always with Apple is a subtly incompatible variant with a number of quirks. It is not publicly available. The TAS2770 variant is known as TAS5770L, and does not require incompatible handling. Much as with the Cirrus codec patches, I do not expect that we will get any official acknowledgement that these parts exist from TI, however I would be delighted to be proven wrong. This series has been living in the downstream Asahi kernel tree[1] for over two years, and has been tested by many thousands of users by this point[2]. v4 drops the TDM idle TX slot behaviour patches. I experimented with the API discussed in v3, however this did not work on any of the machines I tested it with. More tweaking is probably needed.

2025-04-14xfs: add tunable threshold parameter for triggering zone GCHans Holmberg
Presently we start garbage collection late - when we start running out of free zones to backfill max_open_zones. This is a reasonable default as it minimizes write amplification. The longer we wait, the more blocks are invalidated and reclaim cost less in terms of blocks to relocate. Starting this late however introduces a risk of GC being outcompeted by user writes. If GC can't keep up, user writes will be forced to wait for free zones with high tail latencies as a result. This is not a problem under normal circumstances, but if fragmentation is bad and user write pressure is high (multiple full-throttle writers) we will "bottom out" of free zones. To mitigate this, introduce a zonegc_low_space tunable that lets the user specify a percentage of how much of the unused space that GC should keep available for writing. A high value will reclaim more of the space occupied by unused blocks, creating a larger buffer against write bursts. This comes at a cost as write amplification is increased. To illustrate this using a sample workload, setting zonegc_low_space to 60% avoids high (500ms) max latencies while increasing write amplification by 15%.

2025-04-11net: Retire DCCP socket.Kuniyuki Iwashima
DCCP was orphaned in 2021 by commit 054c4610bd05 ("MAINTAINERS: dccp: move Gerrit Renker to CREDITS"), which noted that the last maintainer had been inactive for five years. In recent years, it has become a playground for syzbot, and most changes to DCCP have been odd bug fixes triggered by syzbot. Apart from that, the only changes have been driven by treewide or networking API updates or adjustments related to TCP. Thus, in 2023, we announced we would remove DCCP in 2025 via commit b144fcaf46d4 ("dccp: Print deprecation notice."). Since then, only one individual has contacted the netdev mailing list. [0] There is ongoing research for Multipath DCCP. The repository is hosted on GitHub [1], and development is not taking place through the upstream community. While the repository is published under the GPLv2 license, the scheduling part remains proprietary, with a LICENSE file [2] stating: "This is not Open Source software." The researcher mentioned a plan to address the licensing issue, upstream the patches, and step up as a maintainer, but there has been no further communication since then. Maintaining DCCP for a decade without any real users has become a burden. Therefore, it's time to remove it. Removing DCCP will also provide significant benefits to TCP. It allows us to freely reorganize the layout of struct inet_connection_sock, which is currently shared with DCCP, and optimize it to reduce the number of cachelines accessed in the TCP fast path. Note that we keep DCCP netfilter modules as requested.

2025-04-11dt-bindings: serial: Add compatible for Renesas RZ/T2H SoC in sciThierry Bultel
RSCI of RZ/T2H SoC (a.k.a r9a09g077), as a lot of similarities with SCI in other Renesas SoC like G2L, G3S, V2L; However, it has a different set of registers, and in addition to serial, this IP also supports SCIe (encoder), SmartCard, i2c and spi. This is why the 'renesas,sci' fallback for generic SCI does not apply for it.
