tcp: allow again tcp_disconnect() when threads are waiting
As reported by Tom, .NET and applications build on top of it rely
on connect(AF_UNSPEC) to async cancel pending I/O operations on TCP
socket.
The blamed commit below caused a regression, as such cancellation
can now fail.
As suggested by Eric, this change addresses the problem explicitly
causing blocking I/O operation to terminate immediately (with an error)
when a concurrent disconnect() is executed.
Instead of tracking the number of threads blocked on a given socket,
track the number of disconnect() issued on such socket. If such counter
changes after a blocking operation releasing and re-acquiring the socket
lock, error out the current operation.

net: macsec: indicate next pn update when offloading
Indicate next PN update using update_pn flag in macsec_context. Offloaded MACsec implementations does not know whether or not the MACSEC_SA_ATTR_PN attribute was passed for an SA update and assume that next PN should always updated, but this is not always true. The PN can be reset to its initial value using the following command: $ ip macsec set macsec0 tx sa 0 off #octeontx2-pf case Or, the update PN command will succeed even if the driver does not support PN updates. $ ip macsec set macsec0 tx sa 0 pn 1 on #mscc phy driver case Comparing the initial PN with the new PN value is not a solution. When the user updates the PN using its initial value the command will succeed, even if the driver does not support it. Like this: $ ip macsec add macsec0 tx sa 0 pn 1 on key 00 \ ead3664f508eb06c40ac7104cdae4ce5 $ ip macsec set macsec0 tx sa 0 pn 1 on #mlx5 case Signed-off-by: Radu Pirea (NXP OSS) <radu-nicolae.pirea@oss.nxp.com> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: Paolo Abeni <pabeni@redhat.com> |

net: mana: Fix oversized sge0 for GSO packets
Handle the case when GSO SKB linear length is too large.
MANA NIC requires GSO packets to put only the header part to SGE0,
otherwise the TX queue may stop at the HW level.
So, use 2 SGEs for the skb linear part which contains more than the
packet header.

tcp: fix quick-ack counting to count actual ACKs of new data
This commit fixes quick-ack counting so that it only considers that a
quick-ack has been provided if we are sending an ACK that newly
acknowledges data.
The code was erroneously using the number of data segments in outgoing
skbs when deciding how many quick-ack credits to remove. This logic
does not make sense, and could cause poor performance in
request-response workloads, like RPC traffic, where requests or
responses can be multi-segment skbs.
When a TCP connection decides to send N quick-acks, that is to
accelerate the cwnd growth of the congestion control module
controlling the remote endpoint of the TCP connection. That quick-ack
decision is purely about the incoming data and outgoing ACKs. It has
nothing to do with the outgoing data or the size of outgoing data.
And in particular, an ACK only serves the intended purpose of allowing
the remote congestion control to grow the congestion window quickly if
the ACK is ACKing or SACKing new data.
The fix is simple: only count packets as serving the goal of the
quickack mechanism if they are ACKing/SACKing new data. We can tell
whether this is the case by checking inet_csk_ack_scheduled(), since
we schedule an ACK exactly when we are ACKing/SACKing new data.

cpuidle, ACPI: Evaluate LPI arch_flags for broadcast timer
Arm® Functional Fixed Hardware Specification defines LPI states,
which provide an architectural context loss flags field that can
be used to describe the context that might be lost when an LPI
state is entered.
- Core context Lost
- General purpose registers.
- Floating point and SIMD registers.
- System registers, include the System register based
- generic timer for the core.
- Debug register in the core power domain.
- PMU registers in the core power domain.
- Trace register in the core power domain.
- Trace context loss
- GICR
- GICD
Qualcomm's custom CPUs preserves the architectural state,
including keeping the power domain for local timers active.
when core is power gated, the local timers are sufficient to
wake the core up without needing broadcast timer.
The patch fixes the evaluation of cpuidle arch_flags, and moves only to
broadcast timer if core context lost is defined in ACPI LPI.

netfilter: handle the connecting collision properly in nf_conntrack_proto_sctp
In Scenario A and B below, as the delayed INIT_ACK always changes the peer
vtag, SCTP ct with the incorrect vtag may cause packet loss.
Scenario A: INIT_ACK is delayed until the peer receives its own INIT_ACK
192.168.1.2 > 192.168.1.1: [INIT] [init tag: 1328086772]
192.168.1.1 > 192.168.1.2: [INIT] [init tag: 1414468151]
192.168.1.2 > 192.168.1.1: [INIT ACK] [init tag: 1328086772]

192.168.1.2 > 192.168.1.1: [COOKIE ECHO]
192.168.1.1 > 192.168.1.2: [COOKIE ECHO]
192.168.1.2 > 192.168.1.1: [COOKIE ACK]
Scenario B: INIT_ACK is delayed until the peer completes its own handshake
192.168.1.2 > 192.168.1.1: sctp (1) [INIT] [init tag: 3922216408]
192.168.1.1 > 192.168.1.2: sctp (1) [INIT] [init tag: 144230885]

192.168.1.2 > 192.168.1.1: sctp (1) [COOKIE ACK]
192.168.1.1 > 192.168.1.2: sctp (1) [INIT ACK] [init tag: 3914796021] *
This patch fixes it as below:
In SCTP_CID_INIT processing:
- clear ct->proto.sctp.init[!dir] if ct->proto.sctp.init[dir] &&
ct->proto.sctp.init[!dir]. (Scenario E)
- set ct->proto.sctp.init[dir].
In SCTP_CID_INIT_ACK processing:
- drop it if !ct->proto.sctp.init[!dir] && ct->proto.sctp.vtag[!dir] &&
ct->proto.sctp.vtag[!dir] != ih->init_tag. (Scenario B, Scenario C)
- drop it if ct->proto.sctp.init[dir] && ct->proto.sctp.init[!dir] &&
ct->proto.sctp.vtag[!dir] != ih->init_tag. (Scenario A)
In SCTP_CID_COOKIE_ACK processing:
- clear ct->proto.sctp.init[dir] and ct->proto.sctp.init[!dir].
(Scenario D)
Also, it's important to allow the ct state to move forward with cookie_echo
and cookie_ack from the opposite dir for the collision scenarios.
There are also other Scenarios where it should allow the packet through,
addressed by the processing above:
Scenario C: new CT is created by INIT_ACK.
Scenario D: start INIT on the existing ESTABLISHED ct.
Scenario E: start INIT after the old collision on the existing ESTABLISHED
ct.
192.168.1.2 > 192.168.1.1: sctp (1) [INIT] [init tag: 3922216408]
192.168.1.1 > 192.168.1.2: sctp (1) [INIT] [init tag: 144230885]
(both side are stopped, then start new connection again in hours)

drm/nouveau: exec: report max pushs through getparam
Report the maximum number of IBs that can be pushed with a single DRM_IOCTL_NOUVEAU_EXEC through DRM_IOCTL_NOUVEAU_GETPARAM. While the maximum number of IBs per ring might vary between chipsets, the kernel will make sure that userspace can only push a fraction of the maximum number of IBs per ring per job, such that we avoid a situation where there's only a single job occupying the ring, which could potentially lead to the ring run dry. Using DRM_IOCTL_NOUVEAU_GETPARAM to report the maximum number of IBs that can be pushed with a single DRM_IOCTL_NOUVEAU_EXEC implies that all channels of a given device have the same ring size.

ipv4/fib: send notify when delete source address routes
After deleting an interface address in fib_del_ifaddr(), the function
scans the fib_info list for stray entries and calls fib_flush() and
fib_table_flush(). Then the stray entries will be deleted silently and no
RTM_DELROUTE notification will be sent.
This lack of notification can make routing daemons, or monitor like
`ip monitor route` miss the routing changes. e.g.
+ ip link add dummy1 type dummy
+ ip link add dummy2 type dummy
+ ip link set dummy1 up
+ ip link set dummy2 up
+ ip addr add 192.168.5.5/24 dev dummy1
+ ip route add 7.7.7.0/24 dev dummy2 src 192.168.5.5
+ ip -4 route
7.7.7.0/24 dev dummy2 scope link src 192.168.5.5
192.168.5.0/24 dev dummy1 proto kernel scope link src 192.168.5.5
+ ip monitor route
+ ip addr del 192.168.5.5/24 dev dummy1
Deleted 192.168.5.0/24 dev dummy1 proto kernel scope link src 192.168.5.5
Deleted broadcast 192.168.5.255 dev dummy1 table local proto kernel scope link src 192.168.5.5
Deleted local 192.168.5.5 dev dummy1 table local proto kernel scope host src 192.168.5.5
As Ido reminded, fib_table_flush() isn't only called when an address is
deleted, but also when an interface is deleted or put down. The lack of
notification in these cases is deliberate. And commit

mm: hugetlb: add huge page size param to set_huge_pte_at()
Patch series "Fix set_huge_pte_at() panic on arm64", v2. This series fixes a bug in arm64's implementation of set_huge_pte_at(), which can result in an unprivileged user causing a kernel panic. The problem was triggered when running the new uffd poison mm selftest for HUGETLB memory. This test (and the uffd poison feature) was merged for v6.5-rc7. Ideally, I'd like to get this fix in for v6.6 and I've cc'ed stable (correctly this time) to get it backported to v6.5, where the issue first showed up. Description of Bug ================== arm64's huge pte implementation supports multiple huge page sizes, some of which are implemented in the page table with multiple contiguous entries. So set_huge_pte_at() needs to work out how big the logical pte is, so that it can also work out how many physical ptes (or pmds) need to be written. It previously did this by grabbing the folio out of the pte and querying its size. However, there are cases when the pte being set is actually a swap entry. But this also used to work fine, because for huge ptes, we only ever saw migration entries and hwpoison entries. And both of these types of swap entries have a PFN embedded, so the code would grab that and everything still worked out. But over time, more calls to set_huge_pte_at() have been added that set swap entry types that do not embed a PFN. And this causes the code to go bang. The triggering case is for the uffd poison test, commit |

maple_tree: add MAS_UNDERFLOW and MAS_OVERFLOW states
When updating the maple tree iterator to avoid rewalks, an issue was
introduced when shifting beyond the limits. This can be seen by trying to
go to the previous address of 0, which would set the maple node to
MAS_NONE and keep the range as the last entry.
Subsequent calls to mas_find() would then search upwards from mas->last
and skip the value at mas->index/mas->last. This showed up as a bug in
mprotect which skips the actual VMA at the current range after attempting
to go to the previous VMA from 0.
Since MAS_NONE may already be set when searching for a value that isn't
contained within a node, changing the handling of MAS_NONE in mas_find()
would make the code more complicated and error prone. Furthermore, there
was no way to tell which limit was hit, and thus which action to take
(next or the entry at the current range).
This solution is to add two states to track what happened with the
previous iterator action. This allows for the expected behaviour of the
next command to return the correct item (either the item at the range
requested, or the next/previous).
Tests are also added and updated accordingly.

maple_tree: add mas_is_active() to detect in-tree walks
Patch series "maple_tree: Fix mas_prev() state regression". Pedro Falcato retported an mprotect regression [1] which was bisected back to the iterator changes for maple tree. Root cause analysis showed the mas_prev() running off the end of the VMA space (previous from 0) followed by mas_find(), would skip the first value. This patchset introduces maple state underflow/overflow so the sequence of calls on the maple state will return what the user expects. Users who encounter this bug may see mprotect(), userfaultfd_register(), and mlock() fail on VMAs mapped with address 0. This patch (of 2): Instead of constantly checking each possibility of the maple state, create a fast path that will skip over checking unlikely states.

ATA fixes for 6.6-rc4
A larger than usual set of fixes for 6.6-rc4 due to the unexpected
number of fixes needed to address ATA disks suspend/resume issues.
In more details:
- Add missing additionalProperties on child nodes to the pata-common DT
bindings (Rob).
- Fix handling of the REPORT SUPPORTED OPERATION CODES command to
ignore reserved bits (Niklas).
- Increase port multiplier soft reset timeout to accomodate slow
devices and avoid issues on wakeup (Matthias).
- A couple of minor code fixes to avoid compilation warnings in
libata-core and libata-eh (me).
- Many patches from me to address suspend/resume issues, and in
particular a potential deadlock on resume due to the SCSI disk driver
resume operation not being synchronized with libata EH port resume
handling. This is addressed by changing the scsi disk driver disk
start/stop control to allow libata to execute disk suspend (spin
down) and resume (spin up) on its own during system suspend/resume.
Runtime suspend/resume control remains with the SCSI disk driver.
Other fixes include:
- Fix libata power management request issuing to avoid races.
- Establish a link between ATA ports and SCSI devices to order PM
operations.
- Fix device removal to avoid issues with driver rmmod removal.
- Fix synchronization of libata device rescan and SCSI disk resume
operation.
- Remove libsas PM operations as suspend/resume is handled directly
by the sas controller resume.
- Fix the SCSI disk driver to not issue commands to suspended disks,
thus avoiding potential system lock-up on resume.

scsi: Do not attempt to rescan suspended devices
scsi_rescan_device() takes a scsi device lock before executing a device
handler and device driver rescan methods. Waiting for the completion of
any command issued to the device by these methods will thus be done with
the device lock held. As a result, there is a risk of deadlocking within
the power management code if scsi_rescan_device() is called to handle a
device resume with the associated scsi device not yet resumed.
Avoid such situation by checking that the target scsi device is in the
running state, that is, fully capable of executing commands, before
proceeding with the rescan and bailout returning -EWOULDBLOCK otherwise.
With this error return, the caller can retry rescaning the device after
a delay.
The state check is done with the device lock held and is thus safe
against incoming suspend power management operations.

ata: libata-scsi: Disable scsi device manage_system_start_stop
The introduction of a device link to create a consumer/supplier relationship between the scsi device of an ATA device and the ATA port of that ATA device fixes the ordering of system suspend and resume operations. For suspend, the scsi device is suspended first and the ata port after it. This is fine as this allows the synchronize cache and START STOP UNIT commands issued by the scsi disk driver to be executed before the ata port is disabled. For resume operations, the ata port is resumed first, followed by the scsi device. This allows having the request queue of the scsi device to be unfrozen after the ata port resume is scheduled in EH, thus avoiding to see new requests prematurely issued to the ATA device. Since libata sets manage_system_start_stop to 1, the scsi disk resume operation also results in issuing a START STOP UNIT command to the device being resumed so that the device exits standby power mode. However, restoring the ATA device to the active power mode must be synchronized with libata EH processing of the port resume operation to avoid either 1) seeing the start stop unit command being received too early when the port is not yet resumed and ready to accept commands, or after the port resume process issues commands such as IDENTIFY to revalidate the device. In this last case, the risk is that the device revalidation fails with timeout errors as the drive is still spun down. Commit |

scsi: sd: Differentiate system and runtime start/stop management
The underlying device and driver of a SCSI disk may have different
system and runtime power mode control requirements. This is because
runtime power management affects only the SCSI disk, while system level
power management affects all devices, including the controller for the
SCSI disk.
For instance, issuing a START STOP UNIT command when a SCSI disk is
runtime suspended and resumed is fine: the command is translated to a
STANDBY IMMEDIATE command to spin down the ATA disk and to a VERIFY
command to wake it up. The SCSI disk runtime operations have no effect
on the ata port device used to connect the ATA disk. However, for
system suspend/resume operations, the ATA port used to connect the
device will also be suspended and resumed, with the resume operation
requiring re-validating the device link and the device itself. In this
case, issuing a VERIFY command to spinup the disk must be done before
starting to revalidate the device, when the ata port is being resumed.
In such case, we must not allow the SCSI disk driver to issue START STOP
UNIT commands.
Allow a low level driver to refine the SCSI disk start/stop management
by differentiating system and runtime cases with two new SCSI device
flags: manage_system_start_stop and manage_runtime_start_stop. These new
flags replace the current manage_start_stop flag. Drivers setting the
manage_start_stop are modifed to set both new flags, thus preserving the
existing start/stop management behavior. For backward compatibility, the
old manage_start_stop sysfs device attribute is kept as a read-only
attribute showing a value of 1 for devices enabling both new flags and 0
otherwise.

ata: libata-scsi: link ata port and scsi device
There is no direct device ancestry defined between an ata_device and
its scsi device which prevents the power management code from correctly
ordering suspend and resume operations. Create such ancestry with the
ata device as the parent to ensure that the scsi device (child) is
suspended before the ata device and that resume handles the ata device
before the scsi device.
The parent-child (supplier-consumer) relationship is established between
the ata_port (parent) and the scsi device (child) with the function
device_add_link(). The parent used is not the ata_device as the PM
operations are defined per port and the status of all devices connected
through that port is controlled from the port operations.
The device link is established with the new function
ata_scsi_slave_alloc(), and this function is used to define the
->slave_alloc callback of the scsi host template of all ata drivers.

SCSI fixes on 20230927
Single fix for libata: older devices don't support command duration limits (CDL) and some don't support report opcodes, meaning there's no way to tell if they support the command or not. Reduce the problems of incorrectly using CDL commands on older devices by checking SCSI spec compliance at SPC-5 (the spec which introduced the command) before turning on CDL.

timers: Tag (hr)timer softirq as hotplug safe
Specific stress involving frequent CPU-hotplug operations, such as
running rcutorture for example, may trigger the following message:
NOHZ tick-stop error: local softirq work is pending, handler #02!!!"
This happens in the CPU-down hotplug process, after
CPUHP_AP_SMPBOOT_THREADS whose teardown callback parks ksoftirqd, and
before the target CPU shuts down through CPUHP_AP_IDLE_DEAD. In this
fragile intermediate state, softirqs waiting for threaded handling may be
forever ignored and eventually reported by the idle task as in the above
example.
However some vectors are known to be safe as long as the corresponding
subsystems have teardown callbacks handling the migration of their
events. The above error message reports pending timers softirq although
this vector can be considered as hotplug safe because the
CPUHP_TIMERS_PREPARE teardown callback performs the necessary migration
of timers after the death of the CPU. Hrtimers also have a similar
hotplug handling.
Therefore this error message, as far as (hr-)timers are concerned, can
be considered spurious and the relevant softirq vectors can be marked as
hotplug safe.

ata: libata-sata: increase PMP SRST timeout to 10s
On certain SATA controllers, softreset fails after wakeup from S2RAM with
the message "softreset failed (1st FIS failed)", sometimes resulting in
drives not being detected again. With the increased timeout, this issue
is avoided. Instead, "softreset failed (device not ready)" is now
logged 1-2 times; this later failure seems to cause fewer problems
however, and the drives are detected reliably once they've spun up and
the probe is retried.
The issue was observed with the primary SATA controller of the QNAP
TS-453B, which is an "Intel Corporation Celeron/Pentium Silver Processor
SATA Controller [8086:31e3] (rev 06)" integrated in the Celeron J4125 CPU,
and the following drives:
- Seagate IronWolf ST12000VN0008
- Seagate IronWolf ST8000NE0004
The SATA controller seems to be more relevant to this issue than the
drives, as the same drives are always detected reliably on the secondary
SATA controller on the same board (an ASMedia 106x) without any "softreset
failed" errors even without the increased timeout.

Pull cxl fixes from Dan Williams:
"A collection of regression fixes, bug fixes, and some small cleanups
to the Compute Express Link code.
The regressions arrived in the v6.5 dev cycle and missed the v6.6
merge window due to my personal absences this cycle. The most
important fixes are for scenarios where the CXL subsystem fails to
parse valid region configurations established by platform firmware.
This is important because agreement between OS and BIOS on the CXL
configuration is fundamental to implementing "OS native" error
handling, i.e. address translation and component failure
identification.
Other important fixes are a driver load error when the BIOS lets the
Linux PCI core handle AER events, but not CXL memory errors.
The other fixex might have end user impact, but for now are only known
to trigger in our test/emulation environment.
Summary:
- Fix multiple scenarios where platform firmware defined regions fail
to be assembled by the CXL core.
- Fix a spurious driver-load failure on platforms that enable OS
native AER, but not OS native CXL error handling.
- Fix a regression detecting "poison" commands when "security"
commands are also defined.
- Fix a cxl_test regression with the move to centralize CXL port
register enumeration in the CXL core.
- Miscellaneous small fixes and cleanups"
