Commit f061c9f7d058 ("Documentation: Document each netlink family") added
a new Python script that is invoked during 'make htmldocs' and which reads
the netlink YAML spec files.
Using the virtualenv from scripts/sphinx-pre-install, we get this new
error wen running 'make htmldocs':
Traceback (most recent call last):
File "./tools/net/ynl/ynl-gen-rst.py", line 26, in <module>

ModuleNotFoundError: No module named 'yaml'
make[2]: *** [Documentation/Makefile:112: Documentation/networking/netlink_spec/rt_link.rst] Error 1
make[1]: *** [Makefile:1708: htmldocs] Error 2
Fix this by adding 'pyyaml' to requirements.txt.
Note: This was somehow present in the original patch submission:
<https://lore.kernel.org/all/20231103135622.250314-1-leitao@debian.org/>
I'm not sure why the pyyaml requirement disappeared in the meantime.

mptcp: add CurrEstab MIB counter
This MIB counter is similar to the one of TCP -- CurrEstab -- available
in /proc/net/snmp. This is useful to quickly list the number of MPTCP
connections without having to iterate over all of them.
Patch 1 prepares its support by adding new helper functions:
- MPTCP_DEC_STATS(): similar to MPTCP_INC_STATS(), but this time to
decrement a counter.
- mptcp_set_state(): similar to tcp_set_state(), to change the state of
an MPTCP socket, and to inc/decrement the new counter when needed.
Patch 2 uses mptcp_set_state() instead of directly calling
inet_sk_state_store() to change the state of MPTCP sockets.
Patch 3 and 4 validate the new feature in MPTCP "join" and "diag"
selftests.

Since commit f5769faeec36 ("net: Namespace-ify sysctl_optmem_max")
optmem_max is per-netns, so need of switching to root namespace.
It seems trivial to keep the old logic working, so going to keep it for
a while (at least, until kernel with netns-optmem_max will be release).
Currently, there is a test that checks that optmem_max limit applies to
TCP-AO keys and a little benchmark that measures linked-list TCP-AO keys
scaling, those are fixed by this.

In unsigned-md5 selftests ip_route_add() is not needed in
client_add_ip(): the route was pre-setup in __test_init() => link_init()
for subnet, rather than a specific ip-address.
Currently, __ip_route_add() mistakenly always sets VRF table
to RT_TABLE_MAIN - this seems to have sneaked in during unsigned-md5
tests debugging. That also explains, why ip_route_add_vrf() ignored
EEXIST, returned by fib6.
Yet, keep EEXIST ignoring in bench-lookups selftests as it's expected
that those selftests may add the same (duplicate) routes.

Commit 9718475e6908 ("socket: Add SO_TIMESTAMPING_NEW") added the new
socket option SO_TIMESTAMPING_NEW. Setting the option is handled in
sk_setsockopt(), querying it was not handled in sk_getsockopt(), though.
Following remarks on an earlier submission of this patch, keep the old
behavior of getsockopt(SO_TIMESTAMPING_OLD) which returns the active
flags even if they actually have been set through SO_TIMESTAMPING_NEW.
The new getsockopt(SO_TIMESTAMPING_NEW) is stricter, returning flags
only if they have been set through the same option.

When a 'DEL_CLIENT' message is received from the remote, the corresponding
server port gets deleted. A DEL_SERVER message is then announced for this
server. As part of handling the subsequent DEL_SERVER message, the name-
server attempts to delete the server port which results in a '-ENOENT' error.
The return value from server_del() is then propagated back to qrtr_ns_worker,
causing excessive error prints.
To address this, return 0 from control_cmd_del_server() without checking the
return value of server_del(), since the above scenario is not an error case
and hence server_del() doesn't have any other error return value.

====================
Introduce PHY listing and link_topology tracking
Here's a V5 of the multi-PHY support series.
At a glance, besides some minor fixes and R'd-by from Andrew, one of the
thing this series does is remove the ASSERT_RTNL() from the
topo_add_phy/del_phy operations.
These operations will take a PHY device and put it into the list of
devices associated to a netdevice. The main thing to protect here is the
list itself, but since we use xarrays, my naive understanding of it is
that it contains its own protection scheme. There shouldn't be a need
for more locking, as the insertion/deletion paths are already hooked
into the PHY connection to a netdev, or disconnection from it.
Now for the rest of the cover :
As a remainder, this ongoing work aims ultimately at supporting complex
link topologies that involve multiplexing multiple PHYs/SFPs on a single
netdevice. As a first step, it's required that we are able to enumerate the
PHYs on a given ethernet interface.
By just doing so, we also improve already-existing use-cases, namely the
copper SFP modules support when a media-converter is used (as we have 2
PHYs on the link, but only one is referenced by net_device.phydev, which
is used on a variety of netlink commands).
The series is architectured as follows :
- The first patch adds the notion of phy_link_topology, which tracks
all PHYs attached to a netdevice.
- Patches 2, 3 and 4 adds some plumbing into SFP and phylib to be able
to connect the dots when building the topology tree, to know which PHY
is connected to which SFP bus, trying not to be too invasive on phylib.
- Patch 5 allows passing a PHY_INDEX to ethnl commands. I'm uncertain about
this, as there are at least 4 netlink commands ( 5 with the one introduced
in patch 7 ) that targets PHYs directly or indirectly, which to me makes
it worth-it to have a generic way to pass a PHY index to commands, however
the approach taken may be too generic.
- Patch 6 is the netlink spec update + ethtool-user.c|h autogenerated code
update (the autogenerated code triggers checkpatch warning though)
- Patch 7 introduces a new netlink command set to list PHYs on a netdevice.
It implements a custom DUMP and GET operation to allow filtered dumps,
that lists all PHYs on a given netdevice. I couldn't use most of ethnl's
plumbing though.
- Patch 8 is the netlink spec update + ethtool-user.c|h update for that
new command
- Patch 8,9,10 and 11 updates the PLCA, strset, cable-test and pse netlink
commands to use the user-provided PHY instead of net_device.phydev.
- Finally patch 12 adds some documentation for this whole work.
Examples
========
Here's a short overview of the kind of operations you can have regarding
the PHY topology. These tests were performed on a MacchiatoBin, which
has 3 interfaces :
eth0 and eth1 have the following layout:
MAC - PHY - SFP
eth2 has this more classic topology :
MAC - PHY - RJ45
finally eth3 has the following topology :
MAC - SFP
When performing a dump with all interfaces down, we don't get any
result, as no PHY has been attached to their respective net_device :
None
The following output is with eth0, eth2 and eth3 up, but no SFP module
inserted in none of the interfaces :
[{'downstream-sfp-name': 'sfp-eth0',
'drvname': 'mv88x3310',
'header': {'dev-index': 2, 'dev-name': 'eth0'},
'id': 0,
'index': 1,
'name': 'f212a600.mdio-mii:00',
'upstream-type': 'mac'},
{'drvname': 'Marvell 88E1510',
'header': {'dev-index': 4, 'dev-name': 'eth2'},
'id': 21040593,
'index': 1,
'name': 'f212a200.mdio-mii:00',
'upstream-type': 'mac'}]
And now is a dump operation with a copper SFP in the eth0 port :
[{'downstream-sfp-name': 'sfp-eth0',
'drvname': 'mv88x3310',
'header': {'dev-index': 2, 'dev-name': 'eth0'},
'id': 0,
'index': 1,
'name': 'f212a600.mdio-mii:00',
'upstream-type': 'mac'},
{'drvname': 'Marvell 88E1111',
'header': {'dev-index': 2, 'dev-name': 'eth0'},
'id': 21040322,
'index': 2,
'name': 'i2c:sfp-eth0:16',
'upstream': {'index': 1, 'sfp-name': 'sfp-eth0'},
'upstream-type': 'phy'},
{'drvname': 'Marvell 88E1510',
'header': {'dev-index': 4, 'dev-name': 'eth2'},
'id': 21040593,
'index': 1,
'name': 'f212a200.mdio-mii:00',
'upstream-type': 'mac'}]
-- Note that this shouldn't actually work as the 88x3310 PHY doesn't allow
a 1G SFP to be connected to its SFP interface, and I don't have a 10G copper SFP,
so for the sake of the demo I applied the following modification, which
of courses gives a non-functionnal link, but the PHY attach still works,
which is what I want to demonstrate :
@@ -488,7 +488,7 @@ static int mv3310_sfp_insert(void *upstream, const struct sfp_eeprom_id *id)
if (iface != PHY_INTERFACE_MODE_10GBASER) {
dev_err(&phydev->mdio.dev, "incompatible SFP module inserted\n");
- return -EINVAL;
+ //return -EINVAL;
}
return 0;
}
Finally an example of the filtered DUMP operation that Jakub suggested
in V1 :
[{'downstream-sfp-name': 'sfp-eth0',
'drvname': 'mv88x3310',
'header': {'dev-index': 2, 'dev-name': 'eth0'},
'id': 0,
'index': 1,
'name': 'f212a600.mdio-mii:00',
'upstream-type': 'mac'},
{'drvname': 'Marvell 88E1111',
'header': {'dev-index': 2, 'dev-name': 'eth0'},
'id': 21040322,
'index': 2,
'name': 'i2c:sfp-eth0:16',
'upstream': {'index': 1, 'sfp-name': 'sfp-eth0'},
'upstream-type': 'phy'}]
And a classic GET operation allows querying a single PHY's info :
{'drvname': 'Marvell 88E1111',
'header': {'dev-index': 2, 'dev-name': 'eth0'},
'id': 21040322,
'index': 2,
'name': 'i2c:sfp-eth0:16',
'upstream': {'index': 1, 'sfp-name': 'sfp-eth0'},
'upstream-type': 'phy'}
Changed in V5:
- Removed the RTNL assertion in the topology ops
- Made the phy_topo_get_phy inline
- Fixed the PSE-PD multi-PHY support by re-adding a wrongly dropped
check
- Fixed some typos in the documentation
- Fixed reverse xmas trees
Changes in V4:
- Dropped the RFC flag
- Made the net_device integration independent to having phylib enabled
- Removed the autogenerated ethtool-user code for the YNL specs
Changes in V3:
- Added RTNL assertions where needed
- Fixed issues in the DUMP code for PHY_GET, which crashed when running it
twice in a row
- Added the documentation, and moved in-source docs around
- renamed link_topology to phy_link_topology
Changes in V2:
- Added the DUMP operation
- Added much more information in the reported data, to be able to reconstruct
precisely the topology tree
- renamed phy_list to link_topology

Link topologies containing multiple network PHYs attached to the same
net_device can be found when using a PHY as a media converter for use
with an SFP connector, on which an SFP transceiver containing a PHY can
be used.
With the current model, the transceiver's PHY can't be used for
operations such as cable testing, timestamping, macsec offload, etc.
The reason being that most of the logic for these configuration, coming
from either ethtool netlink or ioctls tend to use netdev->phydev, which
in multi-phy systems will reference the PHY closest to the MAC.
Introduce a numbering scheme allowing to enumerate PHY devices that
belong to any netdev, which can in turn allow userspace to take more
precise decisions with regard to each PHY's configuration.
The numbering is maintained per-netdev, in a phy_device_list.
The numbering works similarly to a netdevice's ifindex, with
identifiers that are only recycled once INT_MAX has been reached.
This prevents races that could occur between PHY listing and SFP
transceiver removal/insertion.
The identifiers are assigned at phy_attach time, as the numbering
depends on the netdevice the phy is attached to.

The upcoming disk accounting rewrite is not going to be fully
compatible: we're going to have to regenerate accounting both when
upgrading to the new version, and also from downgrading from the new
version, since the new method of doing disk space accounting is a
completely different architecture based on deltas, and synchronizing

superblock; naturally, we now need identifiers that don't change, since
the existing enum is in the order in which they are run and is not
fixed.

BCH_REPLICAS_MAX isn't the actual maximum number of pointers in an
extent, it's the maximum number of dirty pointers.
We don't have a real restriction on the number of cached pointers, and
we don't want a fixed size array here anyways - so switch to
DARRAY_PREALLOCATED().

We sometimes use darrays for quite large buffers - the btree write
buffer in particular needs large buffers, since it must be sized to hold
all the write buffer keys outstanding in the journal.

Move the slowpath (actually growing the darray) to an out-of-line
function; also, add some helpers for the upcoming btree write buffer
rewrite.

peek_upto() checks against the end position and bails out before
FILTER_SNAPSHOTS checks; this is because if we end up at a different
inode number than the original search key none of the keys we see might
be visibile in the current snapshot - we might be looking at inode in a
completely different subvolume.
But this is broken, because when we're iterating over extents we're
checking against the extent start position to decide when to bail out,
and the extent start position isn't monotonically increasing until after
we've run FILTER_SNAPSHOTS.
Fix this by adding a simple inode number check where the old bailout
check was, and moving the main check to the correct position.

====================
netfilter pull request 23-12-22
The following patchset contains Netfilter updates for net-next:
1) Add locking for NFT_MSG_GETSETELEM_RESET requests, to address a
race scenario with two concurrent processes running a dump-and-reset
which exposes negative counters to userspace, from Phil Sutter.
2) Use GFP_KERNEL in pipapo GC, from Florian Westphal.
3) Reorder nf_flowtable struct members, place the read-mostly parts
accessed by the datapath first. From Florian Westphal.
4) Set on dead flag for NFT_MSG_NEWSET in abort path,
from Florian Westphal.
5) Support filtering zone in ctnetlink, from Felix Huettner.
6) Bail out if user tries to redefine an existing chain with different
type in nf_tables.

====================
bpf-next-for-netdev
The following pull-request contains BPF updates for your *net-next* tree.
We've added 22 non-merge commits during the last 3 day(s) which contain
a total of 23 files changed, 652 insertions(+), 431 deletions(-).
The main changes are:
1) Add verifier support for annotating user's global BPF subprogram arguments
with few commonly requested annotations for a better developer experience,
from Andrii Nakryiko.
These tags are:
- Ability to annotate a special PTR_TO_CTX argument
- Ability to annotate a generic PTR_TO_MEM as non-NULL
2) Support BPF verifier tracking of BPF_JNE which helps cases when the compiler
transforms (unsigned) "a > 0" into "if a == 0 goto xxx" and the like, from
Menglong Dong.
3) Fix a warning in bpf_mem_cache's check_obj_size() as reported by LKP, from Hou Tao.
4) Re-support uid/gid options when mounting bpffs which had to be reverted with
the prior token series revert to avoid conflicts, from Daniel Borkmann.
5) Fix a libbpf NULL pointer dereference in bpf_object__collect_prog_relos() found
from fuzzing the library with malformed ELF files, from Mingyi Zhang.
6) Skip DWARF sections in libbpf's linker sanity check given compiler options to
generate compressed debug sections can trigger a rejection due to misalignment,
from Alyssa Ross.
7) Fix an unnecessary use of the comma operator in BPF verifier, from Simon Horman.
8) Fix format specifier for unsigned long values in cpustat sample, from Colin Ian King.

Some r8168 NICs stop working upon system resume:
[ 688.051096] r8169 0000:02:00.1 enp2s0f1: rtl_ep_ocp_read_cond == 0 (loop: 10, delay: 10000).
[ 688.175131] r8169 0000:02:00.1 enp2s0f1: Link is Down
...
[ 691.534611] r8169 0000:02:00.1 enp2s0f1: PCI error (cmd = 0x0407, status_errs = 0x0000)
Not sure if it's related, but those NICs have a BMC device at function
0:
02:00.0 Unassigned class [ff00]: Realtek Semiconductor Co., Ltd. Realtek RealManage BMC [10ec:816e] (rev 1a)
Trial and error shows that increase the loop wait on
rtl_ep_ocp_read_cond to 30 can eliminate the issue, so let
rtl8168ep_driver_start() to wait a bit longer.

The freeing and re-allocation of algorithm are protected by cpool_mutex,
so it doesn't fix an actual use-after-free, but avoids a deserved
refcount_warn_saturate() warning.
A trivial fix for the racy behavior.
