xfrm: Support crypto offload for inbound IPv4 UDP-encapsulated ESP packet
If xfrm_input() is called with UDP_ENCAP_ESPINUDP, the packet is
already processed in UDP layer that removes the UDP header.
Therefore, there should be no much difference to treat it as an
ESP packet in the XFRM stack.
Test: Enabled dir=in IPsec crypto offload, and verified IPv4
UDP-encapsulated ESP packets on both wifi/cellular network

xfrm: Allow UDP encapsulation in crypto offload control path
Unblock this limitation so that SAs with encapsulation specified can be passed to HW drivers. HW drivers can still reject the SA in their implementation of xdo_dev_state_add if the encapsulation is not supported.

xfrm: Support crypto offload for inbound IPv6 ESP packets not in GRO path
IPsec crypt offload supports outbound IPv6 ESP packets, but it doesn't
support inbound IPv6 ESP packets.
This change enables the crypto offload for inbound IPv6 ESP packets
that are not handled through GRO code path. If HW drivers add the
offload information to the skb, the packet will be handled in the
crypto offload rx code path.
Apart from the change in crypto offload rx code path, the change
in xfrm_policy_check is also needed.

xfrm: support sending NAT keepalives in ESP in UDP states
Add the ability to send out RFC-3948 NAT keepalives from the xfrm stack. To use, Userspace sets an XFRM_NAT_KEEPALIVE_INTERVAL integer property when creating XFRM outbound states which denotes the number of seconds between keepalive messages. Keepalive messages are sent from a per net delayed work which iterates over the xfrm states. The logic is guarded by the xfrm state spinlock due to the xfrm state walk iterator. Possible future enhancements: - Adding counters to keep track of sent keepalives. - deduplicate NAT keepalives between states sharing the same nat keepalive parameters. - provisioning hardware offloads for devices capable of implementing this. - revise xfrm state list to use an rcu list in order to avoid running this under spinlock.

The __assign_str() macro logic of the TRACE_EVENT() macro was optimized so that it no longer needs the second argument. The __assign_str() is always matched with __string() field that takes a field name and the source for that field: __string(field, source) The TRACE_EVENT() macro logic will save off the source value and then use that value to copy into the ring buffer via the __assign_str().

r8169: Fix possible ring buffer corruption on fragmented Tx packets.
An issue was found on the RTL8125b when transmitting small fragmented
packets, whereby invalid entries were inserted into the transmit ring
buffer, subsequently leading to calls to dma_unmap_single() with a null
address.
This was caused by rtl8169_start_xmit() not noticing changes to nr_frags
which may occur when small packets are padded (to work around hardware
quirks) in rtl8169_tso_csum_v2().
To fix this, postpone inspecting nr_frags until after any padding has been
applied.

Merge branch 'intel-interpret-set_channels-input-differently'
Jacob Keller says:
====================
intel: Interpret .set_channels() input differently
The ice and idpf drivers can trigger a crash with AF_XDP due to incorrect
interpretation of the asymmetric Tx and Rx parameters in their
.set_channels() implementations:
1. ethtool -l <IFNAME> -> combined: 40
2. Attach AF_XDP to queue 30
3. ethtool -L <IFNAME> rx 15 tx 15
combined number is not specified, so command becomes {rx_count = 15,
tx_count = 15, combined_count = 40}.
4. ethnl_set_channels checks, if there are any AF_XDP of queues from the
new (combined_count + rx_count) to the old one, so from 55 to 40, check
does not trigger.
5. the driver interprets `rx 15 tx 15` as 15 combined channels and deletes
the queue that AF_XDP is attached to.
This is fundamentally a problem with interpreting a request for asymmetric
queues as symmetric combined queues.
Fix the ice and idpf drivers to stop interpreting such requests as a
request for combined queues. Due to current driver design for both ice and
idpf, it is not possible to support requests of the same count of Tx and Rx
queues with independent interrupts, (i.e. ethtool -L <IFNAME> rx 15 tx 15)
so such requests are now rejected.

idpf: Interpret .set_channels() input differently
Unlike ice, idpf does not check, if user has requested at least 1 combined
channel. Instead, it relies on a check in the core code. Unfortunately, the
check does not trigger for us because of the hacky .set_channels()
interpretation logic that is not consistent with the core code.
This naturally leads to user being able to trigger a crash with an invalid
input. This is how:
1. ethtool -l <IFNAME> -> combined: 40
2. ethtool -L <IFNAME> rx 0 tx 0
combined number is not specified, so command becomes {rx_count = 0,
tx_count = 0, combined_count = 40}.
3. ethnl_set_channels checks, if there is at least 1 RX and 1 TX channel,
comparing (combined_count + rx_count) and (combined_count + tx_count)
to zero. Obviously, (40 + 0) is greater than zero, so the core code
deems the input OK.
4. idpf interprets `rx 0 tx 0` as 0 channels and tries to proceed with such
configuration.
The issue has to be solved fundamentally, as current logic is also known to
cause AF_XDP problems in ice [0].
Interpret the command in a way that is more consistent with ethtool
manual [1] (--show-channels and --set-channels) and new ice logic.
Considering that in the idpf driver only the difference between RX and TX
queues forms dedicated channels, change the correct way to set number of
channels to:
ethtool -L <IFNAME> combined 10 /* For symmetric queues */
ethtool -L <IFNAME> combined 8 tx 2 rx 0 /* For asymmetric queues */

ice: Interpret .set_channels() input differently
A bug occurs because a safety check guarding AF_XDP-related queues in
ethnl_set_channels(), does not trigger. This happens, because kernel and
ice driver interpret the ethtool command differently.
How the bug occurs:
1. ethtool -l <IFNAME> -> combined: 40
2. Attach AF_XDP to queue 30
3. ethtool -L <IFNAME> rx 15 tx 15

net: ti: icssg_prueth: Fix NULL pointer dereference in prueth_probe()
In the prueth_probe() function, if one of the calls to emac_phy_connect()
fails due to of_phy_connect() returning NULL, then the subsequent call to
phy_attached_info() will dereference a NULL pointer.
Check the return code of emac_phy_connect and fail cleanly if there is an
error.

tls: fix missing memory barrier in tls_init
In tls_init(), a write memory barrier is missing, and store-store
reordering may cause NULL dereference in tls_{setsockopt,getsockopt}.
CPU0 CPU1
----- -----
// In tls_init()
// In tls_ctx_create()
ctx = kzalloc()
ctx->sk_proto = READ_ONCE(sk->sk_prot) -(1)
// In update_sk_prot()
WRITE_ONCE(sk->sk_prot, tls_prots) -(2)
// In sock_common_setsockopt()
READ_ONCE(sk->sk_prot)->setsockopt()
// In tls_{setsockopt,getsockopt}()
ctx->sk_proto->setsockopt() -(3)
In the above scenario, when (1) and (2) are reordered, (3) can observe
the NULL value of ctx->sk_proto, causing NULL dereference.
To fix it, we rely on rcu_assign_pointer() which implies the release
barrier semantic. By moving rcu_assign_pointer() after ctx->sk_proto is
initialized, we can ensure that ctx->sk_proto are visible when
changing sk->sk_prot.

net: fec: avoid lock evasion when reading pps_enable
The assignment of pps_enable is protected by tmreg_lock, but the read
operation of pps_enable is not. So the Coverity tool reports a lock
evasion warning which may cause data race to occur when running in a
multithread environment. Although this issue is almost impossible to
occur, we'd better fix it, at least it seems more logically reasonable,
and it also prevents Coverity from continuing to issue warnings.

testing: net-drv: use stats64 for testing
Testing a network device that has large numbers of bytes/packets may
overflow. Using stats64 when comparing fixes this problem.
I tripped on this while iterating on a qstats patch for mlx5. See below
for confirmation without my added code that this is a bug.
Before this patch (with added debugging output):
$ NETIF=eth0 tools/testing/selftests/drivers/net/stats.py
KTAP version 1
1..4
ok 1 stats.check_pause
ok 2 stats.check_fec
rstat: 481708634 qstat: 666201639514 key: tx-bytes
not ok 3 stats.pkt_byte_sum
ok 4 stats.qstat_by_ifindex
Note the huge delta above ^^^ in the rtnl vs qstats.
After this patch:
$ NETIF=eth0 tools/testing/selftests/drivers/net/stats.py
KTAP version 1
1..4
ok 1 stats.check_pause
ok 2 stats.check_fec
ok 3 stats.pkt_byte_sum
ok 4 stats.qstat_by_ifindex
It looks like rtnl_fill_stats in net/core/rtnetlink.c will attempt to
copy the 64bit stats into a 32bit structure which is probably why this
behavior is occurring.
To show this is happening, you can get the underlying stats that the
stats.py test uses like this:
$ ./cli.py --spec ../../../Documentation/netlink/specs/rt_link.yaml \
--do getlink --json '{"ifi-index": 7}'
And examine the output (heavily snipped to show relevant fields):
'stats': {
'multicast': 3739197,
'rx-bytes': 1201525399,
'rx-packets': 56807158,
'tx-bytes': 492404458,
'tx-packets': 1200285371,
'stats64': {
'multicast': 3739197,
'rx-bytes': 35561263767,
'rx-packets': 56807158,
'tx-bytes': 666212335338,
'tx-packets': 1200285371,
The stats.py test prior to this patch was using the 'stats' structure
above, which matches the failure output on my system.
Comparing side by side, rx-bytes and tx-bytes, and getting ethtool -S
output:
rx-bytes stats: 1201525399
rx-bytes stats64: 35561263767
rx-bytes ethtool: 36203402638
tx-bytes stats: 492404458
tx-bytes stats64: 666212335338
tx-bytes ethtool: 666215360113
Note that the above was taken from a system with an mlx5 NIC, which only
exposes ndo_get_stats64.
Based on the ethtool output and qstat output, it appears that stats.py
should be updated to use the 'stats64' structure for accurate
comparisons when packet/byte counters get very large.
To confirm that this was not related to the qstats code I was iterating
on, I booted a kernel without my driver changes and re-ran the test
which shows the qstats are skipped (as they don't exist for mlx5):
NETIF=eth0 tools/testing/selftests/drivers/net/stats.py
KTAP version 1
1..4
ok 1 stats.check_pause
ok 2 stats.check_fec
ok 3 stats.pkt_byte_sum # SKIP qstats not supported by the device
ok 4 stats.qstat_by_ifindex # SKIP No ifindex supports qstats
But, fetching the stats using the CLI
$ ./cli.py --spec ../../../Documentation/netlink/specs/rt_link.yaml \
--do getlink --json '{"ifi-index": 7}'
Shows the same issue (heavily snipped for relevant fields only):
'stats': {
'multicast': 105489,
'rx-bytes': 530879526,
'rx-packets': 751415,
'tx-bytes': 2510191396,
'tx-packets': 27700323,
'stats64': {
'multicast': 105489,
'rx-bytes': 530879526,
'rx-packets': 751415,
'tx-bytes': 15395093284,
'tx-packets': 27700323,
Comparing side by side with ethtool -S on the unmodified mlx5 driver:
tx-bytes stats: 2510191396
tx-bytes stats64: 15395093284
tx-bytes ethtool: 17718435810

tracing/treewide: Remove second parameter of __assign_str()
With the rework of how the __string() handles dynamic strings where it
saves off the source string in field in the helper structure[1], the
assignment of that value to the trace event field is stored in the helper
value and does not need to be passed in again.
This means that with:
__string(field, mystring)
Which use to be assigned with __assign_str(field, mystring), no longer
needs the second parameter and it is unused. With this, __assign_str()
will now only get a single parameter.
There's over 700 users of __assign_str() and because coccinelle does not
handle the TRACE_EVENT() macro I ended up using the following sed script:
git grep -l __assign_str | while read a ; do
sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file;
mv /tmp/test-file $a;
done
I then searched for __assign_str() that did not end with ';' as those
were multi line assignments that the sed script above would fail to catch.
Note, the same updates will need to be done for:
__assign_str_len()
__assign_rel_str()
__assign_rel_str_len()
I tested this with both an allmodconfig and an allyesconfig (build only for both).

mm: simplify and improve print_vma_addr() output
Use '%pD' to print out the filename, and print out the actual offset within the file too, rather than just what the virtual address of the mapping is (which doesn't tell you anything about any mapping offsets). Also, use the exact vma_lookup() instead of find_vma() - the latter looks up any vma _after_ the address, which is of questionable value (yes, maybe you fell off the beginning, but you'd be more likely to fall off the end).

x86: improve bitop code generation with clang
This uses the new ASM_INPUT_RM macro to avoid the bad code generation issue that clang has with more generic asm inputs. This ends up avoiding generating code like this: mov %r10,(%rsp) tzcnt (%rsp),%rcx which now becomes just tzcnt %r10,%rcx and in the process ends up also removing a few unnecessary stack frames when the only use was that pointless "asm uses memory location off stack".

x86: improve array_index_mask_nospec() code generation
Don't force the inputs to be 'unsigned long', when the comparison can easily be done in 32-bit if that's more appropriate. Note that while we can look at the inputs to choose an appropriate size for the compare instruction, the output is fixed at 'unsigned long'. That's not technically optimal either, since a 32-bit 'sbbl' would often be sufficient. But for the outgoing mask we don't know how the mask ends up being used (ie we have uses that have an incoming 32-bit array index, but end up using the mask for other things). That said, it only costs the extra REX prefix to always generate the 64-bit mask. [ A 'sbbl' also always technically generates a 64-bit mask, but with the upper 32 bits clear: that's fine for when the incoming index that will be masked is already 32-bit, but not if you use the mask to mask a pointer afterwards, like the file table lookup does ] Cc: Peter Zijlstra <peterz@infradead.org> Cc: H.

clang: work around asm input constraint problems
Work around clang problems with asm constraints that have multiple possibilities, particularly "g" and "rm". Clang seems to turn inputs like that into the most generic form, which is the memory input - but to make matters worse, clang won't even use a possible original memory location, but will spill the value to stack, and use the stack for the asm input. See https://github.com/llvm/llvm-project/issues/20571#issuecomment-980933442 for some explanation of why clang has this strange behavior, but the end result is that "g" and "rm" really end up generating horrid code.

Driver core changes for 6.10-rc1
Here is the small set of driver core and kernfs changes for 6.10-rc1. Nothing major here at all, just a small set of changes for some driver core apis, and minor fixups. Included in here are: - sysfs_bin_attr_simple_read() helper added and used - device_show_string() helper added and used All usages of these were acked by the various maintainers. Also in here are: - kernfs minor cleanup - removed unused functions - typo fix in documentation - pay attention to sysfs_create_link() failures in module.c finally. All of these have been in linux-next for a very long time with no reported problems.

Staging driver changes for 6.10-rc1
Here is the big set of staging driver changes for 6.10-rc1. Not a lot of cleanups happening this kernel release, intern applications must be out of sync at the moment. But we did delete two drivers, wlan-ng and pi433, as they are no longer in use and the developers involved wanted them just gone entirely, allowing us to drop 19k lines from the tree. Other than the normal coding style cleanups here, there has been a lot of work on the vc04_services code, with the intent to finally get that out of staging hopefully soon. It's getting closer, which is nice to see. All of these have been in linux-next for a while with no reported issues.

vfs: Delete the associated dentry when deleting a file
Our applications, built on Elasticsearch[0], frequently create and delete files. These applications operate within containers, some with a memory limit exceeding 100GB. Over prolonged periods, the accumulation of negative dentries within these containers can amount to tens of gigabytes. Upon container exit, directories are deleted. However, due to the numerous associated dentries, this process can be time-consuming. Our users have expressed frustration with this prolonged exit duration, which constitutes our first issue. Simultaneously, other processes may attempt to access the parent directory of the Elasticsearch directories. Since the task responsible for deleting the dentries holds the inode lock, processes attempting directory lookup experience significant delays. This issue, our second problem, is easily demonstrated: - Task 1 generates negative dentries: $ pwd ~/test $ mkdir es && cd es/ && ./create_and_delete_files.sh [ After generating tens of GB dentries ] $ cd ~/test && rm -rf es [ It will take a long duration to finish ] - Task 2 attempts to lookup the 'test/' directory $ pwd ~/test $ ls The 'ls' command in Task 2 experiences prolonged execution as Task 1 is deleting the dentries. We've devised a solution to address both issues by deleting associated dentry when removing a file. Interestingly, we've noted that a similar patch was proposed years ago[1], although it was rejected citing the absence of tangible issues caused by negative dentries. Given our current challenges, we're resubmitting the proposal. All relevant stakeholders from previous discussions have been included for reference. Some alternative solutions are also under discussion[2][3], such as shrinking child dentries outside of the parent inode lock or even asynchronously shrinking child dentries. However, given the straightforward nature of the current solution, I believe this approach is still necessary. [ NOTE! This is a pretty fundamental change in how we deal with unlinking dentries, and it doesn't change the fact that you can have lots of negative dentries from just doing negative lookups. But the kernel test robot is at least initially happy with this from a performance angle, so I'm applying this ASAP just to get more testing and as a "known fix for an issue people hit in real life". Put another way: we should still look at the alternatives, and this patch may get reverted if somebody finds a performance regression on some other load. - Linus ] Suggested-by: Linus Torvalds <torvalds@linux-foundation.org> Signed-off-by: Yafang Shao <laoar.shao@gmail.com> Link: https://github.com/elastic/elasticsearch [0] Link: https://patchwork.kernel.org/project/linux-fsdevel/patch/1502099673-31620-1-git-send-email-wangkai86@huawei.com [1] Link: https://lore.kernel.org/linux-fsdevel/20240511200240.6354-2-torvalds@linux-foundation.org/ [2] Link: https://lore.kernel.org/linux-fsdevel/CAHk-=wjEMf8Du4UFzxuToGDnF3yLaMcrYeyNAaH1NJWa6fwcNQ@mail.gmail.com/ [3] Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Christian Brauner <brauner@kernel.org> Cc: Jan Kara <jack@suse.cz> Cc: Waiman Long <longman@redhat.com> Cc: Matthew Wilcox <willy@infradead.org> Cc: Wangkai <wangkai86@huawei.com> Cc: Colin Walters <walters@verbum.org> Tested-by: kernel test robot <oliver.sang@intel.com> Link: https://lore.kernel.org/all/202405221518.ecea2810-oliver.sang@intel.com/ Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

virtio-pci: Check if is_avq is NULL
[bug] In the virtio_pci_common.c function vp_del_vqs, vp_dev->is_avq is involved to determine whether it is admin virtqueue, but this function vp_dev->is_avq may be empty. For installations, virtio_pci_legacy does not assign a value to vp_dev->is_avq. [fix] Check whether it is vp_dev->is_avq before use.

virtio: delete vq in vp_find_vqs_msix() when request_irq() fails
When request_irq() fails, error path calls vp_del_vqs(). There, as vq is
present in the list, free_irq() is called for the same vector. That
causes following splat:
