net: xsk: introduce XDP_MAX_TX_SKB_BUDGET setsockopt
This patch provides a setsockopt method to let applications leverage to adjust how many descs to be handled at most in one send syscall. It mitigates the situation where the default value (32) that is too small leads to higher frequency of triggering send syscall. Considering the prosperity/complexity the applications have, there is no absolutely ideal suggestion fitting all cases. So keep 32 as its default value like before. The patch does the following things: - Add XDP_MAX_TX_SKB_BUDGET socket option. - Set max_tx_budget to 32 by default in the initialization phase as a per-socket granular control. - Set the range of max_tx_budget as [32, xs->tx->nentries]. The idea behind this comes out of real workloads in production. We use a user-level stack with xsk support to accelerate sending packets and minimize triggering syscalls. When the packets are aggregated, it's not hard to hit the upper bound (namely, 32). The moment user-space stack fetches the -EAGAIN error number passed from sendto(), it will loop to try again until all the expected descs from tx ring are sent out to the driver. Enlarging the XDP_MAX_TX_SKB_BUDGET value contributes to less frequency of sendto() and higher throughput/PPS. Here is what I did in production, along with some numbers as follows: For one application I saw lately, I suggested using 128 as max_tx_budget because I saw two limitations without changing any default configuration: 1) XDP_MAX_TX_SKB_BUDGET, 2) socket sndbuf which is 212992 decided by net.core.wmem_default. As to XDP_MAX_TX_SKB_BUDGET, the scenario behind this was I counted how many descs are transmitted to the driver at one time of sendto() based on [1] patch and then I calculated the possibility of hitting the upper bound. Finally I chose 128 as a suitable value because 1) it covers most of the cases, 2) a higher number would not bring evident results. After twisting the parameters, a stable improvement of around 4% for both PPS and throughput and less resources consumption were found to be observed by strace -c -p xxx: 1) %time was decreased by 7.8% 2) error counter was decreased from 18367 to 572 [1]: https://lore.kernel.org/all/20250619093641.70700-1-kerneljasonxing@gmail.com/ Signed-off-by: Jason Xing <kernelxing@tencent.com> Acked-by: Maciej Fijalkowski <maciej.fijalkowski@intel.com> Link: https://patch.msgid.link/20250704160138.48677-1-kerneljasonxing@gmail.com Signed-off-by: Paolo Abeni <pabeni@redhat.com> |

af_unix: Introduce SO_INQ.
We have an application that uses almost the same code for TCP and AF_UNIX (SOCK_STREAM). TCP can use TCP_INQ, but AF_UNIX doesn't have it and requires an extra syscall, ioctl(SIOCINQ) or getsockopt(SO_MEMINFO) as an alternative. Let's introduce the generic version of TCP_INQ. If SO_INQ is enabled, recvmsg() will put a cmsg of SCM_INQ that contains the exact value of ioctl(SIOCINQ). The cmsg is also included when msg->msg_get_inq is non-zero to make sockets io_uring-friendly. Note that SOCK_CUSTOM_SOCKOPT is flagged only for SOCK_STREAM to override setsockopt() for SOL_SOCKET. By having the flag in struct unix_sock, instead of struct sock, we can later add SO_INQ support for TCP and reuse tcp_sk(sk)->recvmsg_inq. Note also that supporting custom getsockopt() for SOL_SOCKET will need preparation for other SOCK_CUSTOM_SOCKOPT users (UDP, vsock, MPTCP).

net: mctp: add gateway routing support
This change allows for gateway routing, where a route table entry
may reference a routable endpoint (by network and EID), instead of
routing directly to a netdevice.
We add support for a RTM_GATEWAY attribute for netlink route updates,
with an attribute format of:
struct mctp_fq_addr {
unsigned int net;
mctp_eid_t eid;
}
- we need the net here to uniquely identify the target EID, as we no
longer have the device reference directly (which would provide the net
id in the case of direct routes).
This makes route lookups recursive, as a route lookup that returns a
gateway route must be resolved into a direct route (ie, to a device)
eventually. We provide a limit to the route lookups, to prevent infinite
loop routing.
The route lookup populates a new 'nexthop' field in the dst structure,
which now specifies the key for the neighbour table lookup on device
output, rather than using the packet destination address directly.

net: openvswitch: allow providing upcall pid for the 'execute' command
When a packet enters OVS datapath and there is no flow to handle it, packet goes to userspace through a MISS upcall. With per-CPU upcall dispatch mechanism, we're using the current CPU id to select the Netlink PID on which to send this packet. This allows us to send packets from the same traffic flow through the same handler. The handler will process the packet, install required flow into the kernel and re-inject the original packet via OVS_PACKET_CMD_EXECUTE. While handling OVS_PACKET_CMD_EXECUTE, however, we may hit a recirculation action that will pass the (likely modified) packet through the flow lookup again. And if the flow is not found, the packet will be sent to userspace again through another MISS upcall. However, the handler thread in userspace is likely running on a different CPU core, and the OVS_PACKET_CMD_EXECUTE request is handled in the syscall context of that thread. So, when the time comes to send the packet through another upcall, the per-CPU dispatch will choose a different Netlink PID, and this packet will end up processed by a different handler thread on a different CPU. The process continues as long as there are new recirculations, each time the packet goes to a different handler thread before it is sent out of the OVS datapath to the destination port. In real setups the number of recirculations can go up to 4 or 5, sometimes more. There is always a chance to re-order packets while processing upcalls, because userspace will first install the flow and then re-inject the original packet. So, there is a race window when the flow is already installed and the second packet can match it and be forwarded to the destination before the first packet is re-injected. But the fact that packets are going through multiple upcalls handled by different userspace threads makes the reordering noticeably more likely, because we not only have a race between the kernel and a userspace handler (which is hard to avoid), but also between multiple userspace handlers. For example, let's assume that 10 packets got enqueued through a MISS upcall for handler-1, it will start processing them, will install the flow into the kernel and start re-injecting packets back, from where they will go through another MISS to handler-2. Handler-2 will install the flow into the kernel and start re-injecting the packets, while handler-1 continues to re-inject the last of the 10 packets, they will hit the flow installed by handler-2 and be forwarded without going to the handler-2, while handler-2 still re-injects the first of these 10 packets. Given multiple recirculations and misses, these 10 packets may end up completely mixed up on the output from the datapath. Let's allow userspace to specify on which Netlink PID the packets should be upcalled while processing OVS_PACKET_CMD_EXECUTE. This makes it possible to ensure that all the packets are processed by the same handler thread in the userspace even with them being upcalled multiple times in the process. Packets will remain in order since they will be enqueued to the same socket and re-injected in the same order. This doesn't eliminate re-ordering as stated above, since we still have a race between kernel and the userspace thread, but it allows to eliminate races between multiple userspace threads. Userspace knows the PID of the socket on which the original upcall is received, so there is no need to send it up from the kernel. Solution requires storing the value somewhere for the duration of the packet processing. There are two potential places for this: our skb extension or the per-CPU storage. It's not clear which is better, so just following currently used scheme of storing this kind of things along the skb. We still have a decent amount of space in the cb.

devlink: Extend devlink rate API with traffic classes bandwidth management
Introduce support for specifying relative bandwidth shares between
traffic classes (TC) in the devlink-rate API. This new option allows
users to allocate bandwidth across multiple traffic classes in a
single command.
This feature provides a more granular control over traffic management,
especially for scenarios requiring Enhanced Transmission Selection.
Users can now define a relative bandwidth share for each traffic class.
For example, assigning share values of 20 to TC0 (TCP/UDP) and 80 to TC5
(RoCE) will result in TC0 receiving 20% and TC5 receiving 80% of the
total bandwidth. The actual percentage each class receives depends on
the ratio of its share value to the sum of all shares.
Example:
DEV=pci/0000:08:00.0
$ devlink port function rate add $DEV/vfs_group tx_share 10Gbit \
tx_max 50Gbit tc-bw 0:20 1:0 2:0 3:0 4:0 5:80 6:0 7:0
$ devlink port function rate set $DEV/vfs_group \
tc-bw 0:20 1:0 2:0 3:0 4:0 5:20 6:60 7:0
Example usage with ynl:
./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \
--do rate-set --json '{
"bus-name": "pci",
"dev-name": "0000:08:00.0",

{"rate-tc-index": 6, "rate-tc-bw": 0},
{"rate-tc-index": 7, "rate-tc-bw": 0}
]
}'
./tools/net/ynl/cli.py --spec Documentation/netlink/specs/devlink.yaml \
--do rate-get --json '{

neighbor: Add NTF_EXT_VALIDATED flag for externally validated entries
tl;dr
=====
Add a new neighbor flag ("extern_valid") that can be used to indicate to
the kernel that a neighbor entry was learned and determined to be valid
externally. The kernel will not try to remove or invalidate such an
entry, leaving these decisions to the user space control plane. This is
needed for EVPN multi-homing where a neighbor entry for a multi-homed
host needs to be synced across all the VTEPs among which the host is
multi-homed.
Background
==========
In a typical EVPN multi-homing setup each host is multi-homed using a
set of links called ES (Ethernet Segment, i.e., LAG) to multiple leaf
switches (VTEPs). VTEPs that are connected to the same ES are called ES
peers.
When a neighbor entry is learned on a VTEP, it is distributed to both ES
peers and remote VTEPs using EVPN MAC/IP advertisement routes. ES peers
use the neighbor entry when routing traffic towards the multi-homed host
and remote VTEPs use it for ARP/NS suppression.
Motivation
==========
If the ES link between a host and the VTEP on which the neighbor entry
was locally learned goes down, the EVPN MAC/IP advertisement route will
be withdrawn and the neighbor entries will be removed from both ES peers
and remote VTEPs. Routing towards the multi-homed host and ARP/NS
suppression can fail until another ES peer locally learns the neighbor
entry and distributes it via an EVPN MAC/IP advertisement route.
"draft-rbickhart-evpn-ip-mac-proxy-adv-03" [1] suggests avoiding these
intermittent failures by having the ES peers install the neighbor
entries as before, but also injecting EVPN MAC/IP advertisement routes
with a proxy indication. When the previously mentioned ES link goes down
and the original EVPN MAC/IP advertisement route is withdrawn, the ES
peers will not withdraw their neighbor entries, but instead start aging
timers for the proxy indication.
If an ES peer locally learns the neighbor entry (i.e., it becomes
"reachable"), it will restart its aging timer for the entry and emit an
EVPN MAC/IP advertisement route without a proxy indication. An ES peer
will stop its aging timer for the proxy indication if it observes the
removal of the proxy indication from at least one of the ES peers
advertising the entry.
In the event that the aging timer for the proxy indication expired, an
ES peer will withdraw its EVPN MAC/IP advertisement route. If the timer
expired on all ES peers and they all withdrew their proxy
advertisements, the neighbor entry will be completely removed from the
EVPN fabric.
Implementation
==============
In the above scheme, when the control plane (e.g., FRR) advertises a
neighbor entry with a proxy indication, it expects the corresponding
entry in the data plane (i.e., the kernel) to remain valid and not be
removed due to garbage collection or loss of carrier. The control plane
also expects the kernel to notify it if the entry was learned locally
(i.e., became "reachable") so that it will remove the proxy indication
from the EVPN MAC/IP advertisement route. That is why these entries
cannot be programmed with dummy states such as "permanent" or "noarp".
Instead, add a new neighbor flag ("extern_valid") which indicates that
the entry was learned and determined to be valid externally and should
not be removed or invalidated by the kernel. The kernel can probe the
entry and notify user space when it becomes "reachable" (it is initially
installed as "stale"). However, if the kernel does not receive a
confirmation, have it return the entry to the "stale" state instead of
the "failed" state.
In other words, an entry marked with the "extern_valid" flag behaves
like any other dynamically learned entry other than the fact that the
kernel cannot remove or invalidate it.
One can argue that the "extern_valid" flag should not prevent garbage
collection and that instead a neighbor entry should be programmed with
both the "extern_valid" and "extern_learn" flags. There are two reasons
for not doing that:
1. Unclear why a control plane would like to program an entry that the
kernel cannot invalidate but can completely remove.
2. The "extern_learn" flag is used by FRR for neighbor entries learned
on remote VTEPs (for ARP/NS suppression) whereas here we are
concerned with local entries. This distinction is currently irrelevant
for the kernel, but might be relevant in the future.
Given that the flag only makes sense when the neighbor has a valid
state, reject attempts to add a neighbor with an invalid state and with
this flag set. For example:
# ip neigh add 192.0.2.1 nud none dev br0.10 extern_valid
Error: Cannot create externally validated neighbor with an invalid state.
# ip neigh add 192.0.2.1 lladdr 00:11:22:33:44:55 nud stale dev br0.10 extern_valid
# ip neigh replace 192.0.2.1 nud failed dev br0.10 extern_valid
Error: Cannot mark neighbor as externally validated with an invalid state.
The above means that a neighbor cannot be created with the
"extern_valid" flag and flags such as "use" or "managed" as they result
in a neighbor being created with an invalid state ("none") and
immediately getting probed:
# ip neigh add 192.0.2.1 lladdr 00:11:22:33:44:55 nud stale dev br0.10 extern_valid use
Error: Cannot create externally validated neighbor with an invalid state.
However, these flags can be used together with "extern_valid" after the
neighbor was created with a valid state:
# ip neigh add 192.0.2.1 lladdr 00:11:22:33:44:55 nud stale dev br0.10 extern_valid
# ip neigh replace 192.0.2.1 lladdr 00:11:22:33:44:55 nud stale dev br0.10 extern_valid use
One consequence of preventing the kernel from invalidating a neighbor
entry is that by default it will only try to determine reachability
using unicast probes. This can be changed using the "mcast_resolicit"
sysctl:
# sysctl net.ipv4.neigh.br0/10.mcast_resolicit
0
# tcpdump -nn -e -i br0.10 -Q out arp &
# ip neigh replace 192.0.2.1 lladdr 00:11:22:33:44:55 nud stale dev br0.10 extern_valid use

netlink: specs: mptcp: replace underscores with dashes in names
We're trying to add a strict regexp for the name format in the spec.
Underscores will not be allowed, dashes should be used instead.
This makes no difference to C (codegen, if used, replaces special
chars in names) but it gives more uniform naming in Python.

wifi: cfg80211: Report per-radio RTS threshold to userspace
In case of multi-radio wiphys, with per-radio RTS threshold brought into use, RTS threshold for each radio in a wiphy can be recorded in wiphy parameter - wiphy_radio_cfg, as an array. Add a new attribute - NL80211_WIPHY_RADIO_ATTR_RTS_THRESHOLD in nested parameter - NL80211_ATTR_WIPHY_RADIOS. When a request for getting RTS threshold for a particular radio is received, parse the radio id and get the required data. Add this data to the newly added nested attribute NL80211_WIPHY_RADIO_ATTR_RTS_THRESHOLD. Add support to report this data to userspace.

wifi: cfg80211/mac80211: Add support to get radio index
Currently, per-radio attributes are set on per-phy basis, i.e., all the radios present in a wiphy will take attributes values sent from user. But each radio in a wiphy can get different values from userspace based on its requirement. To extend support to set per-radio attributes, add support to get radio index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX, to get user specified radio index for which attributes should be changed. Pass this to individual drivers, so that the drivers can use this radio index to change per-radio attributes when necessary. Currently, per-radio attributes identified are: NL80211_ATTR_WIPHY_TX_POWER_LEVEL NL80211_ATTR_WIPHY_ANTENNA_TX NL80211_ATTR_WIPHY_ANTENNA_RX NL80211_ATTR_WIPHY_RETRY_SHORT NL80211_ATTR_WIPHY_RETRY_LONG NL80211_ATTR_WIPHY_FRAG_THRESHOLD NL80211_ATTR_WIPHY_RTS_THRESHOLD NL80211_ATTR_WIPHY_COVERAGE_CLASS NL80211_ATTR_TXQ_LIMIT NL80211_ATTR_TXQ_MEMORY_LIMIT NL80211_ATTR_TXQ_QUANTUM By default, the radio index is set to -1. This means the attribute should be treated as a global configuration. If the user has not specified any index, then the radio index passed to individual drivers would be -1. This would indicate that the attribute applies to all radios in that wiphy.

KVM: TDX: Exit to userspace for GetTdVmCallInfo
Exit to userspace for TDG.VP.VMCALL<GetTdVmCallInfo> via KVM_EXIT_TDX, to allow userspace to provide information about the support of TDVMCALLs when r12 is 1 for the TDVMCALLs beyond the GHCI base API. GHCI spec defines the GHCI base TDVMCALLs: <GetTdVmCallInfo>, <MapGPA>, <ReportFatalError>, <Instruction.CPUID>, <#VE.RequestMMIO>, <Instruction.HLT>, <Instruction.IO>, <Instruction.RDMSR> and <Instruction.WRMSR>. They must be supported by VMM to support TDX guests. For GetTdVmCallInfo - When leaf (r12) to enumerate TDVMCALL functionality is set to 0, successful execution indicates all GHCI base TDVMCALLs listed above are supported. Update the KVM TDX document with the set of the GHCI base APIs. - When leaf (r12) to enumerate TDVMCALL functionality is set to 1, it indicates the TDX guest is querying the supported TDVMCALLs beyond the GHCI base TDVMCALLs. Exit to userspace to let userspace set the TDVMCALL sub-function bit(s) accordingly to the leaf outputs. KVM could set the TDVMCALL bit(s) supported by itself when the TDVMCALLs don't need support from userspace after returning from userspace and before entering guest. Currently, no such TDVMCALLs implemented, KVM just sets the values returned from userspace.

KVM: TDX: Handle TDG.VP.VMCALL<GetQuote>
Handle TDVMCALL for GetQuote to generate a TD-Quote. GetQuote is a doorbell-like interface used by TDX guests to request VMM to generate a TD-Quote signed by a service hosting TD-Quoting Enclave operating on the host. A TDX guest passes a TD Report (TDREPORT_STRUCT) in a shared-memory area as parameter. Host VMM can access it and queue the operation for a service hosting TD-Quoting enclave. When completed, the Quote is returned via the same shared-memory area. KVM only checks the GPA from the TDX guest has the shared-bit set and drops the shared-bit before exiting to userspace to avoid bleeding the shared-bit into KVM's exit ABI. KVM forwards the request to userspace VMM (e.g. QEMU) and userspace VMM queues the operation asynchronously. KVM sets the return code according to the 'ret' field set by userspace to notify the TDX guest whether the request has been queued successfully or not. When the request has been queued successfully, the TDX guest can poll the status field in the shared-memory area to check whether the Quote generation is completed or not. When completed, the generated Quote is returned via the same buffer. Add KVM_EXIT_TDX as a new exit reason to userspace. Userspace is required to handle the KVM exit reason as the initial support for TDX, by reentering KVM to ensure that the TDVMCALL is complete. While at it, add a note that KVM_EXIT_HYPERCALL also requires reentry with KVM_RUN.

wifi: cfg80211: Add support for link reconfiguration negotiation offload to driver
In the case of SME-in-driver, the driver can internally choose to update the links based on the AP MLD recommendation and do link reconfiguration negotiation with AP MLD. (e.g., After the driver processing the BSS Transition Management request frame received from the AP MLD with Neighbor Report containing Multi-Link element with recommended links information chooses to do link reconfiguration negotiation with AP MLD). To support this, extend cfg80211_mlo_reconf_add_done() and NL80211_CMD_ASSOC_MLO_RECONF to indicate added links information for driver-initiated link reconfiguration requests. For removed links, the driver indicates links information using the NL80211_CMD_LINKS_REMOVED event for driver-initiated cases, the same as supplicant initiated cases. For the driver-initiated case, cfg80211 will receive link reconfiguration result asynchronously from driver so holding BSSes of the accepted add links is needed in the event path. Also, no need of unhold call for the rejected add link BSSes since there was no hold call happened previously. Once the supplicant receives the NL80211_CMD_ASSOC_MLO_RECONF event, it needs to process the information about newly added links and install per-link group keys (e.g., GTK/IGTK/BIGTK etc.). In case of the SME-in-driver, using a vendor interface etc. to notify the supplicant to initiate a link reconfiguration request and then supplicant sending command to the cfg80211 can lead to race conditions. The correct design to avoid this is that the driver indicates the cfg80211 directly with the results of the link reconfiguration negotiation.

net: pse-pd: Add support for budget evaluation strategies
This patch introduces the ability to configure the PSE PI budget evaluation strategies. Budget evaluation strategies is utilized by PSE controllers to determine which ports to turn off first in scenarios such as power budget exceedance. The pis_prio_max value is used to define the maximum priority level supported by the controller. Both the current priority and the maximum priority are exposed to the user through the pse_ethtool_get_status call. This patch add support for two mode of budget evaluation strategies. 1. Static Method: This method involves distributing power based on PD classification. It’s straightforward and stable, the PSE core keeping track of the budget and subtracting the power requested by each PD’s class. Advantages: Every PD gets its promised power at any time, which guarantees reliability. Disadvantages: PD classification steps are large, meaning devices request much more power than they actually need. As a result, the power supply may only operate at, say, 50% capacity, which is inefficient and wastes money. Priority max value is matching the number of PSE PIs within the PSE. 2. Dynamic Method: To address the inefficiencies of the static method, vendors like Microchip have introduced dynamic power budgeting, as seen in the PD692x0 firmware. This method monitors the current consumption per port and subtracts it from the available power budget. When the budget is exceeded, lower-priority ports are shut down. Advantages: This method optimizes resource utilization, saving costs. Disadvantages: Low-priority devices may experience instability. Priority max value is set by the PSE controller driver. For now, budget evaluation methods are not configurable and cannot be mixed. They are hardcoded in the PSE driver itself, as no current PSE controller supports both methods.

net: ethtool: remove duplicate defines for family info
Commit under fixes switched to uAPI generation from the YAML
spec. A number of custom defines were left behind, mostly
for commands very hard to express in YAML spec.
Among what was left behind was the name and version of
the generic netlink family. Problem is that the codegen
always outputs those values so we ended up with a duplicated,
differently named set of defines.
Provide naming info in YAML and remove the incorrect defines.

vxlan: Support MC routing in the underlay
Locally-generated MC packets have so far not been subject to MC routing. Instead an MC-enabled installation would maintain the MC routing tables, and separately from that the list of interfaces to send packets to as part of the VXLAN FDB and MDB. In a previous patch, a ip_mr_output() and ip6_mr_output() routines were added for IPv4 and IPv6. All locally generated MC traffic is now passed through these functions. For reasons of backward compatibility, an SKB (IPCB / IP6CB) flag guards the actual MC routing. This patch adds logic to set the flag, and the UAPI to enable the behavior.

USB/Thunderbolt changes for 6.16-rc1
Here is the big set of USB and Thunderbolt changes for 6.16-rc1.
Included in here are the following:
- USB offload support for audio devices. I think this takes the
record for the most number of patch series (30+) over the longest
period of time (2+ years) to get merged properly. Many props go to
Wesley Cheng for seeing this effort through, they took a major
out-of-tree hacked-up-monstrosity that was created by multiple
vendors for their specific devices, got it all merged into a
semi-coherent set of changes, and got all of the different major
subsystems to agree on how this should be implemented both with
changes to their code as well as userspace apis, AND wrangled the
hardware companies into agreeing to go forward with this, despite
making them all redo work they had already done in their private
device trees. This feature offers major power savings on embedded
devices where a USB audio stream can continue to flow while the rest
of the system is sleeping, something that devices running on battery
power really care about. There are still some more small tweaks
left to be done here, and those patches are still out for review and
arguing among the different hardware companies, but this is a major
step forward and a great example of how to do upstream development
well.
- small number of thunderbolt fixes and updates, things seem to be
slowing down here (famous last words...)
- xhci refactors and reworking to try to handle some rough corner
cases in some hardware implementations where things don't always
work properly
- typec driver updates
- USB3 power management reworking and updates
- Removal of some old and orphaned UDC gadget drivers that had not
been used in a very long time, dropping over 11 thousand lines from
the tree, always a nice thing, making up for the 12k lines added for
the USB offload feature.
- lots of little updates and fixes in different drivers
All of these have been in linux-next for over 2 weeks, the USB offload
logic has been in there for 8 weeks now, with no reported issues

Overall, a lot of individual changes, but nothing major, just the
normal constant forward progress of new device support and cleanups to
existing subsystems. Highlights in here are:
- Large IIO driver updates and additions and device tree changes
- Android binder bugfixes and logfile fixes
- mhi driver updates
- comedi driver updates
- counter driver updates and additions
- coresight driver updates and additions
- echo driver removal as there are no in-kernel users of it
- nvmem driver updates
- spmi driver updates
- new amd-sbi driver "subsystem" and drivers added
- rust miscdriver binding documentation fix
- other small driver fixes and updates (uio, w1, acrn, hpet,
xillybus, cardreader drivers, fastrpc and others)
All of these have been in linux-next for quite a while with no
reported problems"

drm/xe/pxp: Clarify PXP queue creation behavior if PXP is not ready
The expected flow of operations when using PXP is to query the PXP status and wait for it to transition to "ready" before attempting to create an exec_queue. This flow is followed by the Mesa driver, but there is no guarantee that an incorrectly coded (or malicious) app will not attempt to create the queue first without querying the status. Therefore, we need to clarify what the expected behavior of the queue creation ioctl is in this scenario. Currently, the ioctl always fails with an -EBUSY code no matter the error, but for consistency it is better to distinguish between "failed to init" (-EIO) and "not ready" (-EBUSY), the same way the query ioctl does. Note that, while this is a change in the return code of an ioctl, the behavior of the ioctl in this particular corner case was not clearly spec'd, so no one should have been relying on it (and we know that Mesa, which is the only known userspace for this, didn't). v2: Minor rework of the doc (Rodrigo) Fixes: |
