livepatch: Call klp_match_callback() in klp_find_callback() to avoid code duplication
The implementation of function klp_match_callback() is identical to the partial implementation of function klp_find_callback(). So call function klp_match_callback() in function klp_find_callback() instead of the duplicated code.

This was a not-too-busy cycle for documentation; highlights include:
- The beginnings of a set of translations into Spanish, headed up by Carlos
Bilbao.
- More Chinese translations.
- A change to the Sphinx "alabaster" theme by default for HTML generation.
Unlike the previous default (Read the Docs), alabaster is shipped with
Sphinx by default, reducing the number of other dependencies that need to
be installed. It also (IMO) produces a cleaner and more readable result.
- The ability to render the documentation into the texinfo format
(something Sphinx could always do, we just never wired it up until now).
Plus the usual collection of typo fixes, build-warning fixes, and minor
updates.

Pull random number generator updates from Jason Donenfeld:
- Replace prandom_u32_max() and various open-coded variants of it,
there is now a new family of functions that uses fast rejection
sampling to choose properly uniformly random numbers within an
interval:
get_random_u32_below(ceil) - [0, ceil)
get_random_u32_above(floor) - (floor, U32_MAX]
get_random_u32_inclusive(floor, ceil) - [floor, ceil]
Coccinelle was used to convert all current users of
prandom_u32_max(), as well as many open-coded patterns, resulting in
improvements throughout the tree.
I'll have a "late" 6.1-rc1 pull for you that removes the now unused
prandom_u32_max() function, just in case any other trees add a new
use case of it that needs to converted. According to linux-next,
there may be two trivial cases of prandom_u32_max() reintroductions
that are fixable with a 's/.../.../'. So I'll have for you a final
conversion patch doing that alongside the removal patch during the
second week.
This is a treewide change that touches many files throughout.
- More consistent use of get_random_canary().
- Updates to comments, documentation, tests, headers, and
simplification in configuration.
- The arch_get_random*_early() abstraction was only used by arm64 and
wasn't entirely useful, so this has been replaced by code that works
in all relevant contexts.
- The kernel will use and manage random seeds in non-volatile EFI
variables, refreshing a variable with a fresh seed when the RNG is
initialized. The RNG GUID namespace is then hidden from efivarfs to
prevent accidental leakage.
These changes are split into random.c infrastructure code used in the
EFI subsystem, in this pull request, and related support inside of
EFISTUB, in Ard's EFI tree. These are co-dependent for full
functionality, but the order of merging doesn't matter.
- Part of the infrastructure added for the EFI support is also used for
an improvement to the way vsprintf initializes its siphash key,
replacing an sleep loop wart.
- The hardware RNG framework now always calls its correct random.c
input function, add_hwgenerator_randomness(), rather than sometimes
going through helpers better suited for other cases.
- The add_latent_entropy() function has long been called from the fork
handler, but is a no-op when the latent entropy gcc plugin isn't
used, which is fine for the purposes of latent entropy.
But it was missing out on the cycle counter that was also being mixed
in beside the latent entropy variable. So now, if the latent entropy
gcc plugin isn't enabled, add_latent_entropy() will expand to a call
to add_device_randomness(NULL, 0), which adds a cycle counter,
without the absent latent entropy variable.
- The RNG is now reseeded from a delayed worker, rather than on demand
when used. Always running from a worker allows it to make use of the
CPU RNG on platforms like S390x, whose instructions are too slow to
do so from interrupts. It also has the effect of adding in new inputs
more frequently with more regularity, amounting to a long term
transcript of random values. Plus, it helps a bit with the upcoming
vDSO implementation (which isn't yet ready for 6.2).
- The jitter entropy algorithm now tries to execute on many different
CPUs, round-robining, in hopes of hitting even more memory latencies
and other unpredictable effects. It also will mix in a cycle counter
when the entropy timer fires, in addition to being mixed in from the
main loop, to account more explicitly for fluctuations in that timer
firing. And the state it touches is now kept within the same cache
line, so that it's assured that the different execution contexts will
cause latencies.

Merge branch 'bridge-mcast-extensions-for-evpn'
Ido Schimmel says:
====================
bridge: mcast: Extensions for EVPN
tl;dr
=====
This patchset creates feature parity between user space and the kernel
and allows the former to install and replace MDB port group entries with
a source list and associated filter mode. This is required for EVPN use
cases where multicast state is not derived from snooped IGMP/MLD
packets, but instead derived from EVPN routes exchanged by the control
plane in user space.
Background
==========
IGMPv3 [1] and MLDv2 [2] differ from earlier versions of the protocols
in that they add support for source-specific multicast. That is, hosts
can advertise interest in listening to a particular multicast address
only from specific source addresses or from all sources except for
specific source addresses.
In kernel 5.10 [3][4], the bridge driver gained the ability to snoop
IGMPv3/MLDv2 packets and install corresponding MDB port group entries.
For example, a snooped IGMPv3 Membership Report that contains a single
MODE_IS_EXCLUDE record for group 239.10.10.10 with sources 192.0.2.1,
192.0.2.2, 192.0.2.20 and 192.0.2.21 would trigger the creation of these
entries:
# bridge -d mdb show
dev br0 port veth1 grp 239.10.10.10 src 192.0.2.21 temp filter_mode include proto kernel blocked
dev br0 port veth1 grp 239.10.10.10 src 192.0.2.20 temp filter_mode include proto kernel blocked
dev br0 port veth1 grp 239.10.10.10 src 192.0.2.2 temp filter_mode include proto kernel blocked
dev br0 port veth1 grp 239.10.10.10 src 192.0.2.1 temp filter_mode include proto kernel blocked
dev br0 port veth1 grp 239.10.10.10 temp filter_mode exclude source_list 192.0.2.21/0.00,192.0.2.20/0.00,192.0.2.2/0.00,192.0.2.1/0.00 proto kernel
While the kernel can install and replace entries with a filter mode and
source list, user space cannot. It can only add EXCLUDE entries with an
empty source list, which is sufficient for IGMPv2/MLDv1, but not for
IGMPv3/MLDv2.
Use cases where the multicast state is not derived from snooped packets,
but instead derived from routes exchanged by the user space control
plane require feature parity between user space and the kernel in terms
of MDB configuration. Such a use case is detailed in the next section.
Motivation
==========
RFC 7432 [5] defines a "MAC/IP Advertisement route" (type 2) [6] that
allows NVE switches in the EVPN network to advertise and learn
reachability information for unicast MAC addresses. Traffic destined to
a unicast MAC address can therefore be selectively forwarded to a single
NVE switch behind which the MAC is located.
The same is not true for IP multicast traffic. Such traffic is simply
flooded as BUM to all NVE switches in the broadcast domain (BD),
regardless if a switch has interested receivers for the multicast stream
or not. This is especially problematic for overlay networks that make
heavy use of multicast.
The issue is addressed by RFC 9251 [7] that defines a "Selective
Multicast Ethernet Tag Route" (type 6) [8] which allows NVE switches in
the EVPN network to advertise multicast streams that they are interested
in. This is done by having each switch suppress IGMP/MLD packets from
being transmitted to the NVE network and instead communicate the
information over BGP to other switches.
As far as the bridge driver is concerned, the above means that the
multicast state (i.e., {multicast address, group timer, filter-mode,
(source records)}) for the VXLAN bridge port is not populated by the
kernel from snooped IGMP/MLD packets (they are suppressed), but instead
by user space. Specifically, by the routing daemon that is exchanging
EVPN routes with other NVE switches.
Changes are obviously also required in the VXLAN driver, but they are
the subject of future patchsets. See the "Future work" section.
Implementation
==============
The user interface is extended to allow user space to specify the filter
mode of the MDB port group entry and its source list. Replace support is
also added so that user space would not need to remove an entry and
re-add it only to edit its source list or filter mode, as that would
result in packet loss. Example usage:
# bridge mdb replace dev br0 port dummy10 grp 239.1.1.1 permanent \
source_list 192.0.2.1,192.0.2.3 filter_mode exclude proto zebra
# bridge -d -s mdb show
dev br0 port dummy10 grp 239.1.1.1 src 192.0.2.3 permanent filter_mode include proto zebra blocked 0.00
dev br0 port dummy10 grp 239.1.1.1 src 192.0.2.1 permanent filter_mode include proto zebra blocked 0.00
dev br0 port dummy10 grp 239.1.1.1 permanent filter_mode exclude source_list 192.0.2.3/0.00,192.0.2.1/0.00 proto zebra 0.00
The netlink interface is extended with a few new attributes in the
RTM_NEWMDB request message:
[ struct nlmsghdr ]
[ struct br_port_msg ]
[ MDBA_SET_ENTRY ]
struct br_mdb_entry
[ MDBA_SET_ENTRY_ATTRS ]
[ MDBE_ATTR_SOURCE ]
struct in_addr / struct in6_addr
[ MDBE_ATTR_SRC_LIST ] // new
[ MDBE_SRC_LIST_ENTRY ]
[ MDBE_SRCATTR_ADDRESS ]
struct in_addr / struct in6_addr
[ ...]
[ MDBE_ATTR_GROUP_MODE ] // new
u8
[ MDBE_ATTR_RTPORT ] // new
u8
No changes are required in RTM_NEWMDB responses and notifications, as
all the information can already be dumped by the kernel today.
Testing
=======
Tested with existing bridge multicast selftests: bridge_igmp.sh,
bridge_mdb_port_down.sh, bridge_mdb.sh, bridge_mld.sh,
bridge_vlan_mcast.sh.
In addition, added many new test cases for existing as well as for new
MDB functionality.
Patchset overview
=================
Patches #1-#8 are non-functional preparations for the core changes in
later patches.
Patches #9-#10 allow user space to install (*, G) entries with a source
list and associated filter mode. Specifically, patch #9 adds the
necessary kernel plumbing and patch #10 exposes the new functionality to
user space via a few new attributes.
Patch #11 allows user space to specify the routing protocol of new MDB
port group entries so that a routing daemon could differentiate between
entries installed by it and those installed by an administrator.
Patch #12 allows user space to replace MDB port group entries. This is
useful, for example, when user space wants to add a new source to a
source list. Instead of deleting a (*, G) entry and re-adding it with an
extended source list (which would result in packet loss), user space can
simply replace the current entry.
Patches #13-#14 add tests for existing MDB functionality as well as for
all new functionality added in this patchset.
Future work
===========
The VXLAN driver will need to be extended with an MDB so that it could
selectively forward IP multicast traffic to NVE switches with interested
receivers instead of simply flooding it to all switches as BUM.
The idea is to reuse the existing MDB interface for the VXLAN driver in
a similar way to how the FDB interface is shared between the bridge and
VXLAN drivers.
From command line perspective, configuration will look as follows:
# bridge mdb add dev br0 port vxlan0 grp 239.1.1.1 permanent \
filter_mode exclude source_list 198.50.100.1,198.50.100.2
# bridge mdb add dev vxlan0 port vxlan0 grp 239.1.1.1 permanent \
filter_mode include source_list 198.50.100.3,198.50.100.4 \
dst 192.0.2.1 dst_port 4789 src_vni 2
# bridge mdb add dev vxlan0 port vxlan0 grp 239.1.1.1 permanent \
filter_mode exclude source_list 198.50.100.1,198.50.100.2 \
dst 192.0.2.2 dst_port 4789 src_vni 2
Where the first command is enabled by this set, but the next two will be
the subject of future work.
From netlink perspective, the existing PF_BRIDGE/RTM_*MDB messages will
be extended to the VXLAN driver. This means that a few new attributes
will be added (e.g., 'MDBE_ATTR_SRC_VNI') and that the handlers for
these messages will need to move to net/core/rtnetlink.c. The rtnetlink
code will call into the appropriate driver based on the ifindex
specified in the ancillary header.
iproute2 patches can be found here [9].

bridge: mcast: Support replacement of MDB port group entries
Now that user space can specify additional attributes of port group entries such as filter mode and source list, it makes sense to allow user space to atomically modify these attributes by replacing entries instead of forcing user space to delete the entries and add them back. Replace MDB port group entries when the 'NLM_F_REPLACE' flag is specified in the netlink message header. When a (*, G) entry is replaced, update the following attributes: Source list, state, filter mode, protocol and flags. If the entry is temporary and in EXCLUDE mode, reset the group timer to the group membership interval. If the entry is temporary and in INCLUDE mode, reset the source timers of associated sources to the group membership interval. Examples: # bridge mdb replace dev br0 port dummy10 grp 239.1.1.1 permanent source_list 192.0.2.1,192.0.2.2 filter_mode include # bridge -d -s mdb show dev br0 port dummy10 grp 239.1.1.1 src 192.0.2.2 permanent filter_mode include proto static 0.00 dev br0 port dummy10 grp 239.1.1.1 src 192.0.2.1 permanent filter_mode include proto static 0.00 dev br0 port dummy10 grp 239.1.1.1 permanent filter_mode include source_list 192.0.2.2/0.00,192.0.2.1/0.00 proto static 0.00 # bridge mdb replace dev br0 port dummy10 grp 239.1.1.1 permanent source_list 192.0.2.1,192.0.2.3 filter_mode exclude proto zebra # bridge -d -s mdb show dev br0 port dummy10 grp 239.1.1.1 src 192.0.2.3 permanent filter_mode include proto zebra blocked 0.00 dev br0 port dummy10 grp 239.1.1.1 src 192.0.2.1 permanent filter_mode include proto zebra blocked 0.00 dev br0 port dummy10 grp 239.1.1.1 permanent filter_mode exclude source_list 192.0.2.3/0.00,192.0.2.1/0.00 proto zebra 0.00 # bridge mdb replace dev br0 port dummy10 grp 239.1.1.1 temp source_list 192.0.2.4,192.0.2.3 filter_mode include proto bgp # bridge -d -s mdb show dev br0 port dummy10 grp 239.1.1.1 src 192.0.2.4 temp filter_mode include proto bgp 0.00 dev br0 port dummy10 grp 239.1.1.1 src 192.0.2.3 temp filter_mode include proto bgp 0.00 dev br0 port dummy10 grp 239.1.1.1 temp filter_mode include source_list 192.0.2.4/259.44,192.0.2.3/259.44 proto bgp 0.00 Signed-off-by: Ido Schimmel <idosch@nvidia.com> Acked-by: Nikolay Aleksandrov <razor@blackwall.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

bridge: mcast: Allow user space to specify MDB entry routing protocol
Add the 'MDBE_ATTR_RTPORT' attribute to allow user space to specify the routing protocol of the MDB port group entry. Enforce a minimum value of 'RTPROT_STATIC' to prevent user space from using protocol values that should only be set by the kernel (e.g., 'RTPROT_KERNEL'). Maintain backward compatibility by defaulting to 'RTPROT_STATIC'. The protocol is already visible to user space in RTM_NEWMDB responses and notifications via the 'MDBA_MDB_EATTR_RTPROT' attribute. The routing protocol allows a routing daemon to distinguish between entries configured by it and those configured by the administrator. Once MDB flush is supported, the protocol can be used as a criterion according to which the flush is performed. Examples: # bridge mdb add dev br0 port dummy10 grp 239.1.1.1 permanent proto kernel Error: integer out of range. # bridge mdb add dev br0 port dummy10 grp 239.1.1.1 permanent proto static # bridge mdb add dev br0 port dummy10 grp 239.1.1.1 src 192.0.2.1 permanent proto zebra # bridge mdb add dev br0 port dummy10 grp 239.1.1.2 permanent source_list 198.51.100.1,198.51.100.2 filter_mode include proto 250 # bridge -d mdb show dev br0 port dummy10 grp 239.1.1.2 src 198.51.100.2 permanent filter_mode include proto 250 dev br0 port dummy10 grp 239.1.1.2 src 198.51.100.1 permanent filter_mode include proto 250 dev br0 port dummy10 grp 239.1.1.2 permanent filter_mode include source_list 198.51.100.2/0.00,198.51.100.1/0.00 proto 250 dev br0 port dummy10 grp 239.1.1.1 src 192.0.2.1 permanent filter_mode include proto zebra dev br0 port dummy10 grp 239.1.1.1 permanent filter_mode exclude proto static Signed-off-by: Ido Schimmel <idosch@nvidia.com> Acked-by: Nikolay Aleksandrov <razor@blackwall.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

Add new netlink attributes to the RTM_NEWMDB request that allow user space to add (*, G) with a source list and filter mode.

bridge: mcast: Add support for (*, G) with a source list and filter mode
In preparation for allowing user space to add (*, G) entries with a source list and associated filter mode, add the necessary plumbing to handle such requests. Extend the MDB configuration structure with a currently empty source array and filter mode that is currently hard coded to EXCLUDE. Add the source entries and the corresponding (S, G) entries before making the new (*, G) port group entry visible to the data path. Handle the creation of each source entry in a similar fashion to how it is created from the data path in response to received Membership Reports: Create the source entry, arm the source timer (if needed), add a corresponding (S, G) forwarding entry and finally mark the source entry as installed (by user space). Add the (S, G) entry by populating an MDB configuration structure and calling br_mdb_add_group_sg() as if a new entry is created by user space, with the sole difference that the 'src_entry' field is set to make sure that the group timer of such entries is never armed. Note that it is not currently possible to add more than 32 source entries to a port group entry. If this proves to be a problem we can either increase 'PG_SRC_ENT_LIMIT' or avoid forcing a limit on entries created by user space.

bridge: mcast: Avoid arming group timer when (S, G) corresponds to a source
User space will soon be able to install a (*, G) with a source list, prompting the creation of a (S, G) entry for each source. In this case, the group timer of the (S, G) entry should never be set. Solve this by adding a new field to the MDB configuration structure that denotes whether the (S, G) corresponds to a source or not. The field will be set in a subsequent patch where br_mdb_add_group_sg() is called in order to create a (S, G) entry for each user provided source.

bridge: mcast: Add a flag for user installed source entries
There are a few places where the bridge driver differentiates between (S, G) entries installed by the kernel (in response to Membership Reports) and those installed by user space. One of them is when deleting an (S, G) entry corresponding to a source entry that is being deleted. While user space cannot currently add a source entry to a (*, G), it can add an (S, G) entry that later corresponds to a source entry created by the reception of a Membership Report. If this source entry is later deleted because its source timer expired or because the (*, G) entry is being deleted, the bridge driver will not delete the corresponding (S, G) entry if it was added by user space as permanent. This is going to be a problem when the ability to install a (*, G) with a source list is exposed to user space. In this case, when user space installs the (*, G) as permanent, then all the (S, G) entries corresponding to its source list will also be installed as permanent. When user space deletes the (*, G), all the source entries will be deleted and the expectation is that the corresponding (S, G) entries will be deleted as well. Solve this by introducing a new source entry flag denoting that the entry was installed by user space. When the entry is deleted, delete the corresponding (S, G) entry even if it was installed by user space as permanent, as the flag tells us that it was installed in response to the source entry being created. The flag will be set in a subsequent patch where source entries are created in response to user requests.

Subsequent patches will create more differences between both entry types. Namely, filter mode and source list can only be specified for (*, G) entries.

i40e: Fix the inability to attach XDP program on downed interface
Whenever trying to load XDP prog on downed interface, function i40e_xdp was passing vsi->rx_buf_len field to i40e_xdp_setup() which was equal 0. i40e_open() calls i40e_vsi_configure_rx() which configures that field, but that only happens when interface is up. When it is down, i40e_open() is not being called, thus vsi->rx_buf_len is not set. Solution for this is calculate buffer length in newly created function - i40e_calculate_vsi_rx_buf_len() that return actual buffer length. Buffer length is being calculated based on the same rules applied previously in i40e_vsi_configure_rx() function. Fixes: |

Also, IFF_MASTER/SLAVE are historical flags used in bonding and eql, as Jiri mentioned, the new devices like Team, Failover do not use this flag. So as Jiri suggested, this patch adds IFF_NO_ADDRCONF in priv_flags of the device to indicate no ipv6 addconf, and uses it in bonding and moves IFF_SLAVE flag setting back to its original place.

stmmac: fix potential division by 0
When the MAC is connected to a 10 Mb/s PHY and the PTP clock is derived
from the MAC reference clock (default), the clk_ptp_rate becomes too
small and the calculated sub second increment becomes 0 when computed by
the stmmac_config_sub_second_increment() function within
stmmac_init_tstamp_counter().
Therefore, the subsequent div_u64 in stmmac_init_tstamp_counter()
operation triggers a divide by 0 exception as shown below.
