nilfs2: reject devices with insufficient block count
The current sanity check for nilfs2 geometry information lacks checks for
the number of segments stored in superblocks, so even for device images
that have been destructively truncated or have an unusually high number of
segments, the mount operation may succeed.
This causes out-of-bounds block I/O on file system block reads or log
writes to the segments, the latter in particular causing
"a_ops->writepages" to repeatedly fail, resulting in sync_inodes_sb() to
hang.
Fix this issue by checking the number of segments stored in the superblock
and avoiding mounting devices that can cause out-of-bounds accesses. To
eliminate the possibility of overflow when calculating the number of
blocks required for the device from the number of segments, this also adds
a helper function to calculate the upper bound on the number of segments
and inserts a check using it.

lib/test_vmalloc.c: avoid garbage in page array
It turns out that alloc_pages_bulk_array() does not treat the page_array
parameter as an output parameter, but rather reads the array and skips any
entries that have already been allocated.
This is somewhat unexpected and breaks this test, as we allocate the pages
array uninitialised on the assumption it will be overwritten.
As a result, the test was referencing uninitialised data and causing the
PFN to not be valid and thus a WARN_ON() followed by a null pointer deref
and panic.
In addition, this is an array of pointers not of struct page objects, so we
need only allocate an array with elements of pointer size.

sizeof(struct page *) rather than sizeof(struct page).

nilfs2: fix possible out-of-bounds segment allocation in resize ioctl
Syzbot reports that in its stress test for resize ioctl, the log writing
function nilfs_segctor_do_construct hits a WARN_ON in
nilfs_segctor_truncate_segments().
It turned out that there is a problem with the current implementation of
the resize ioctl, which changes the writable range on the device (the
range of allocatable segments) at the end of the resize process.
This order is necessary for file system expansion to avoid corrupting the
superblock at trailing edge. However, in the case of a file system
shrink, if log writes occur after truncating out-of-bounds trailing
segments and before the resize is complete, segments may be allocated from
the truncated space.
The userspace resize tool was fine as it limits the range of allocatable
segments before performing the resize, but it can run into this issue if
the resize ioctl is called alone.
Fix this issue by changing nilfs_sufile_resize() to update the range of
allocatable segments immediately after successful truncation of segment
space in case of file system shrink.
And both of them have their range [sh_addr ... sh_addr+sh_size] on the
area pointed by `e_entry`.
This causes that image->start is calculated twice, once for .text and
another time for .text.hot. The second calculation leaves image->start
in a random location.

mm/uffd: allow vma to merge as much as possible
We used to not pass in the pgoff correctly when register/unregister uffd
regions, it caused incorrect behavior on vma merging and can cause
mergeable vmas being separate after ioctls return.
For example, when we have:
vma1(range 0-9, with uffd), vma2(range 10-19, no uffd)
Then someone unregisters uffd on range (5-9), it should logically become:
vma1(range 0-4, with uffd), vma2(range 5-19, no uffd)
But with current code we'll have:
vma1(range 0-4, with uffd), vma3(range 5-9, no uffd), vma2(range 10-19, no uffd)
This patch allows such merge to happen correctly before ioctl returns.
This behavior seems to have existed since the 1st day of uffd. Since
pgoff for vma_merge() is only used to identify the possibility of vma
merging, meanwhile here what we did was always passing in a pgoff smaller
than what we should, so there should have no other side effect besides not
merging it. Let's still tentatively copy stable for this, even though I
don't see anything will go wrong besides vma being split (which is mostly

mm/uffd: fix vma operation where start addr cuts part of vma
Patch series "mm/uffd: Fix vma merge/split", v2.
This series contains two patches that fix vma merge/split for userfaultfd

Patch 1 fixes a regression since 6.1+ due to something we overlooked when
converting to maple tree apis. The plan is we use patch 1 to replace the
commit "2f628010799e (mm: userfaultfd: avoid passing an invalid range to
vma_merge())" in mm-hostfixes-unstable tree if possible, so as to bring
uffd vma operations back aligned with the rest code again.
Patch 2 fixes a long standing issue that vma can be left unmerged even if
we can for either uffd register or unregister.
Many thanks to Lorenzo on either noticing this issue from the assert
movement patch, looking at this problem, and also provided a reproducer on
the unmerged vma issue [1].
It seems vma merging with uffd paths is broken with either
register/unregister, where right now we can feed wrong parameters to
vma_merge() and it's found by recent patch which moved asserts upwards in
vma_merge() by Lorenzo Stoakes:
It's possible that "start" is contained within vma but not clamped to its
start. We need to convert this into either "cannot merge" case or "can
merge" case 4 which permits subdivision of prev by assigning vma to prev.
As we loop, each subsequent VMA will be clamped to the start.
This patch will eliminate the report and make sure vma_merge() calls will
become legal again.

RDMA/mlx5: Fix affinity assignment
The cited commit aimed to ensure that Virtual Functions (VFs) assign a
queue affinity to a Queue Pair (QP) to distribute traffic when
the LAG master creates a hardware LAG. If the affinity was set while
the hardware was not in LAG, the firmware would ignore the affinity value.
However, this commit unintentionally assigned an affinity to QPs on the LAG
master's VPORT even if the RDMA device was not marked as LAG-enabled.
In most cases, this was not an issue because when the hardware entered
hardware LAG configuration, the RDMA device of the LAG master would be
destroyed and a new one would be created, marked as LAG-enabled.
The problem arises when a user configures Equal-Cost Multipath (ECMP).
In ECMP mode, traffic can be directed to different physical ports based on
the queue affinity, which is intended for use by VPORTS other than the
E-Switch manager. ECMP mode is supported only if both E-Switch managers are
in switchdev mode and the appropriate route is configured via IP. In this
configuration, the RDMA device is not destroyed, and we retain the RDMA
device that is not marked as LAG-enabled.
To ensure correct behavior, Send Queues (SQs) opened by the E-Switch
manager through verbs should be assigned strict affinity. This means they
will only be able to communicate through the native physical port
associated with the E-Switch manager. This will prevent the firmware from
assigning affinity and will not allow the SQs to be remapped in case of
failover.

Previously we used the core device associated to the IB device in order
to do the Q-counters query to the FW, but in LAG mode it is possible
that the core device isn't the one that created this VF.
Hence instead of using the core device to query the Q-counters
we use the ESW core device which is guaranteed to be that of the VF.
RDMA/mlx5: Remove vport Q-counters dependency on normal Q-counters
Previously the Q-counters initialization assumed that the vport Q-counters
structures and the normal Q-counters structures are identical in size,
and hence when a Q-counter was added to normal Q-counters structure but
not to the vport Q-counters struct it would lead to that counter name
being NULL in switchdev mode, which could cause the kernel crash below.
Currently break the dependency between those two structure and always
use the appropriate struct size, in order to remove the assumption
that both structure sizes are equal.
Previously Q-counters data was being allocated over the PF for all of
the available vports, however that isn't necessary.
Since each VF or SF has a Q-counter allocated for itself.
So we only need to allocate two counters data structures, one for the
device counters, and one for all the other vports to expose the
representors, since they only need to read from it in order to
determine mainly counters numbers and names, so they can all share.
This in turn also solves a bug we previously had where we couldn't
switch the device to switchdev mode when there were more than 128 SF/VFs
configured, since that is the maximum amount of Q-counters available for
a single port

RDMA/mlx5: Create an indirect flow table for steering anchor
A misbehaved user can create a steering anchor that points to a kernel
flow table and then destroy the anchor without freeing the associated
STC. This creates a problem as the kernel can't destroy the flow
table since there is still a reference to it. As a result, this can
exhaust all available flow table resources, preventing other users from
using the RDMA device.
To prevent this problem, a solution is implemented where a special flow
table with two steering rules is created when a user creates a steering
anchor for the first time. The rules include one that drops all traffic
and another that points to the kernel flow table. If the steering anchor
is destroyed, only the rule pointing to the kernel's flow table is removed.
Any traffic reaching the special flow table after that is dropped.
Since the special flow table is not destroyed when the steering anchor is
destroyed, any issues are prevented from occurring. The remaining resources
are only destroyed when the RDMA device is destroyed, which happens after
all DEVX objects are freed, including the STCs, thus mitigating the issue.

In the last step of the EEH recovery process, the EEH driver calls into
bnx2x_io_resume() to re-initialize the NIC hardware via the function
bnx2x_nic_load(). If an error occurs during bnx2x_nic_load(), OS and
hardware resources are released and an error code is returned to the
caller. When called from bnx2x_io_resume(), the return code is ignored
and the network interface is brought up unconditionally. Later attempts
to send a packet via this interface result in a page fault due to a null
pointer reference.
This patch checks the return code of bnx2x_nic_load(), prints an error
message if necessary, and does not enable the interface.

selftests: mptcp: skip tests not supported by old kernels (part 2)
After a few years of increasing test coverage in the MPTCP selftests, we
realised [1] the last version of the selftests is supposed to run on old
kernels without issues.
Supporting older versions is not that easy for this MPTCP case: these
selftests are often validating the internals by checking packets that
are exchanged, when some MIB counters are incremented after some
actions, how connections are getting opened and closed in some cases,
etc. In other words, it is not limited to the socket interface between
the userspace and the kernelspace.
In addition to that, the current MPTCP selftests run a lot of different
sub-tests but the TAP13 protocol used in the selftests don't support
sub-tests: one failure in sub-tests implies that the whole selftest is
seen as failed at the end because sub-tests are not tracked. It is then
important to skip sub-tests not supported by old kernels.
To minimise the modifications and reduce the complexity to support old
versions, the idea is to look at external signs and skip the whole
selftests or just some sub-tests before starting them. This cannot be
applied in all cases.
This second part focuses on marking different sub-tests as skipped if
some MPTCP features are not supported. A few techniques are used here:
- Before starting some tests:
- Check if a file (sysctl knob) is present: that's what patch 13/14 is
doing for the userspace PM feature.
- Check if a symbol is present in /proc/kallsyms: patch 1/14 adds some
helpers in mptcp_lib.sh to ease its use. Then these helpers are used
in patches 2, 3, 4, 10, 11 and 14/14.
- Set a flag and get the status to check if a feature is supported:
patch 8/14 is doing that with the 'fullmesh' flag.
- After having launched the tests:
- Retrieve the counters after a test and check if they are different
than 0. Similar to the check with the flag, that's not ideal but in
this case, the counters were already present before the introduction
of MPTCP but they have been supported by MPTCP sockets only later.
Patches 5 and 6/14 are using this technique.
Before skipping tests, SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES env var
value is checked: if it is set to 1, the test is marked as "failed"
instead of "skipped". MPTCP public CI expects to have all features
supported and it sets this env var to 1 to catch regressions in these
new checks.
Patches 7/14 and 9/14 are a bit different because they don't skip tests:
- Patch 7/14 retrieves the default values instead of using hardcoded
ones because these default values have been modified at some points.
Then the comparisons are done with the default values.
- patch 9/14 relaxes the expected returned size from MPTCP's getsockopt
because the different structures gathering various info can get new
fields and get bigger over time. We cannot expect that the userspace
is using the same structure as the kernel.
Patch 12/14 marks the test as "skipped" instead of "failed" if the "ip"
tool is not available.
In this second part, the "mptcp_join" selftest is not modified yet. This
will come soon after in the third part with quite a few patches.
Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
One of them is the new listener events linked to the path-manager
introduced by commit f8c9dfbd875b ("mptcp: add pm listener events").
It is possible to look for "mptcp_event_pm_listener" in kallsyms to know
in advance if the kernel supports this feature and skip these sub-tests
if the feature is not supported.

has been modified in commit 71fc704768f6 ("tcp: add rcv_wnd and

The userspace can also expect a smaller size if it is compiled with old
uAPI kernel headers.

threshold, 0 for the moment. We can also only compared sizes with the
ones set by the kernel.

In order to prevent this, move the point of possible failure above the
point where the reference counter is incremented. Also save any
meaningful return values to be applied to the return data at the
appropriate point in time.

net/sched: taprio: fix slab-out-of-bounds Read in taprio_dequeue_from_txq
As shown in [1], out-of-bounds access occurs in two cases:
1)when the qdisc of the taprio type is used to replace the previously
configured taprio, count and offset in tc_to_txq can be set to 0. In this
case, the value of *txq in taprio_next_tc_txq() will increases
continuously. When the number of accessed queues exceeds the number of
queues on the device, out-of-bounds access occurs.
2)When packets are dequeued, taprio can be deleted. In this case, the tc
rule of dev is cleared. The count and offset values are also set to 0. In
this case, out-of-bounds access is also caused.
Now the restriction on the queue number is added.

net: renesas: rswitch: Fix timestamp feature after all descriptors are used
The timestamp descriptors were intended to act cyclically. Descriptors
from index 0 through gq->ring_size - 1 contain actual information, and
the last index (gq->ring_size) should have LINKFIX to indicate
the first index 0 descriptor. However, the LINKFIX value is missing,
causing the timestamp feature to stop after all descriptors are used.
To resolve this issue, set the LINKFIX to the timestamp descritors.

net/sched: act_pedit: Parse L3 Header for L4 offset
Instead of relying on skb->transport_header being set correctly, opt
instead to parse the L3 header length out of the L3 headers for both
IPv4/IPv6 when the Extended Layer Op for tcp/udp is used. This fixes a
bug if GRO is disabled, when GRO is disabled skb->transport_header is
set by __netif_receive_skb_core() to point to the L3 header, it's later
fixed by the upper protocol layers, but act_pedit will receive the SKB
before the fixups are completed. The existing behavior causes the
following to edit the L3 header if GRO is disabled instead of the UDP
header:
tc filter add dev eth0 ingress protocol ip flower ip_proto udp \
dst_ip 192.168.1.3 action pedit ex munge udp set dport 18053
Also re-introduce a rate-limited warning if we were unable to extract
the header offset when using the 'ex' interface.
