21 months agonilfs2: fix incomplete buffer cleanup in nilfs_btnode_abort_change_key()
Ryusuke Konishi [Sat, 13 May 2023 10:24:28 +0000 (19:24 +0900)]
nilfs2: fix incomplete buffer cleanup in nilfs_btnode_abort_change_key()

A syzbot fault injection test reported that nilfs_btnode_create_block, a
helper function that allocates a new node block for b-trees, causes a
kernel BUG for disk images where the file system block size is smaller
than the page size.

This was due to unexpected flags on the newly allocated buffer head, and
it turned out to be because the buffer flags were not cleared by
nilfs_btnode_abort_change_key() after an error occurred during a b-tree
update operation and the buffer was later reused in that state.

Fix this issue by using nilfs_btnode_delete() to abandon the unused
preallocated buffer in nilfs_btnode_abort_change_key().

21 months agoio_uring/io-wq: don't clear PF_IO_WORKER on exit

io_uring/io-wq: don't clear PF_IO_WORKER on exit

A recent commit gated the core dumping task exit logic on current->flags
remaining consistent in terms of PF_{IO,USER}_WORKER at task exit time.
This exposed a problem with the io-wq handling of that, which explicitly
clears PF_IO_WORKER before calling do_exit().

The reasons for this manual clear of PF_IO_WORKER is historical, where
io-wq used to potentially trigger a sleep on exit. As the io-wq thread
is exiting, it should not participate any further accounting. But these
days we don't need to rely on current->flags anymore, so we can safely
remove the PF_IO_WORKER clearing.

Inside css_task_iter_start/next/end, css_set_lock is hold and then

another list(right side), then it->cset_head points to the old list head
and it->cset_pos->next points to the head node of new list, which can't
be used as struct css_set.

To fix this issue, switch from all css_sets to only scgrp's css_sets to
patch in-flight iterators to preserve correct iteration, and then
update it->cset_head as well.

perhaps the bus/interconnect it is connected to, or even the connection
to the SMMU.

Work around this by setting SDHCI_QUIRK2_BROKEN_64_BIT_DMA to avoid
using 64-bit addresses.

smb/client: print "Unknown" instead of bogus link speed value

The virtio driver for Linux guests will not set a link speed to its
paravirtualized NICs.  This will be seen as -1 in the ethernet layer, and
when some servers (e.g. samba) fetches it, it's converted to an unsigned
value (and multiplied by 1000 * 1000), so in client side we end up with:

1)      Speed: 4294967295000000 bps

in DebugData.

This patch introduces a helper that returns a speed string (in Mbps or
Gbps) if interface speed is valid (>= SPEED_10 and <= SPEED_800000), or
"Unknown" otherwise.

The reason to not change the value in iface->speed is because we don't
know the real speed of the HW backing the server NIC, so let's keep
considering these as the fastest NICs available.

Also print "Capabilities: None" when the interface doesn't support any.

blk-cgroup: Flush stats before releasing blkcg_gq

As noted by Michal, the blkg_iostat_set's in the lockless list hold
reference to blkg's to protect against their removal. Those blkg's
hold reference to blkcg. When a cgroup is being destroyed,
cgroup_rstat_flush() is only called at css_release_work_fn() which
is called when the blkcg reference count reaches 0. This circular
dependency will prevent blkcg and some blkgs from being freed after
they are made offline.

It is less a problem if the cgroup to be destroyed also has other
controllers like memory that will call cgroup_rstat_flush() which will
clean up the reference count. If block is the only controller that uses
rstat, these offline blkcg and blkgs may never be freed leaking more
and more memory over time.

To prevent this potential memory leak:

- flush blkcg per-cpu stats list in __blkg_release(), when no new stat
can be added

- add global blkg_stat_lock for covering concurrent parent blkg stat
update

- don't grab bio->bi_blkg reference when adding the stats into blkcg's
per-cpu stat list since all stats are guaranteed to be consumed before
releasing blkg instance, and grabbing blkg reference for stats was the
most fragile part of original patch

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.

RDMA/mlx5: Fix Q-counters per vport allocation

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

Mark Bloch [Mon, 5 Jun 2023 10:33:18 +0000 (13:33 +0300)]
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.

bnx2x: fix page fault following EEH recovery

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.

Matthieu Baerts says:

====================
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.

21 months agoigb: Fix extts capture value format for 82580/i354/i350
Yuezhen Luan [Wed, 7 Jun 2023 16:41:16 +0000 (09:41 -0700)]
igb: Fix extts capture value format for 82580/i354/i350

82580/i354/i350 features circle-counter-like timestamp registers
that are different with newer i210. The EXTTS capture value in
AUXTSMPx should be converted from raw circle counter value to
timestamp value in resolution of 1 nanosec by the driver.

This issue can be reproduced on i350 nics, connecting an 1PPS
signal to a SDP pin, and run 'ts2phc' command to read external
1PPS timestamp value. On i210 this works fine, but on i350 the
extts is not correctly converted.

The i350/i354/82580's SYSTIM and other timestamp registers are
40bit counters, presenting time range of 2^40 ns, that means these
registers overflows every about 1099s. This causes all these regs
can't be used directly in contrast to the newer i210/i211s.

The igb driver needs to convert these raw register values to
valid time stamp format by using kernel timecounter apis for i350s
families. Here the igb_extts() just forgot to do the convert.

21 months agoping6: Fix send to link-local addresses with VRF.
Guillaume Nault [Wed, 7 Jun 2023 16:05:02 +0000 (18:05 +0200)]
ping6: Fix send to link-local addresses with VRF.

Ping sockets can't send packets when they're bound to a VRF master
device and the output interface is set to a slave device.

For example, when net.ipv4.ping_group_range is properly set, so that
ping6 can use ping sockets, the following kind of commands fails:
  $ ip vrf exec red ping6 fe80::854:e7ff:fe88:4bf1%eth1

What happens is that sk->sk_bound_dev_if is set to the VRF master
device, but 'oif' is set to the real output device. Since both are set
but different, ping_v6_sendmsg() sees their value as inconsistent and
fails.

Fix this by allowing 'oif' to be a slave device of ->sk_bound_dev_if.

This fixes the following kselftest failure:
  $ ./fcnal-test.sh -t ipv6_ping
  [...]
  TEST: ping out, vrf device+address bind - ns-B IPv6 LLA        [FAIL]
