In commit d77e38e612 ("xfrm: Add an IPsec hardware offloading API") we

But this will make xfrm_dev_event() missing if we only enable default XFRM

Then if we set down and unregister an interface with IPsec on it. there
will no xfrm_garbage_collect(), which will cause dev usage count hold and

XAUI allows XGMII to reach an extended distance by using a XGXS layer at
each end of the MAC to PHY link, operating over four Serdes lanes.
10GBASE-KR is a single lane Serdes backplane ethernet connection method
with autonegotiation on the link. Some PHYs use this to connect to the
ethernet interface at 10G speeds, switching to other connection types
when utilising slower speeds.
10GBASE-KR is also used for XFI and SFI to connect to XFP and SFP fiber
modules.

GCC explicitly does not warn for unused static inline functions for
-Wunused-function. The manual states:
Warn whenever a static function is declared but not defined or
a non-inline static function is unused.
Clang does warn for static inline functions that are unused.
It turns out that suppressing the warnings avoids potentially complex
#ifdef directives, which also reduces LOC.
Suppress the warning for clang.

A single BPF_OBJ_GET_INFO_BY_FD cmd is used to obtain the info

The suggested struct bpf_prog_info and struct bpf_map_info are

New fields can be added in the future patch.

BPF_OBJ_GET_INFO_BY_FD cmd for exposing the bpf_prog's and

The obj's info, which will be extended (and get bigger) over time, is

This patch generates an unique ID for each BPF_PROG_LOAD-ed prog.
It is worth to note that each BPF_PROG_LOAD-ed prog will have
a different ID even they have the same bpf instructions.
The ID is generated by the existing idr_alloc_cyclic().
The ID is ranged from [1, INT_MAX). It is allocated in cyclic manner,
so an ID will get reused every 2 billion BPF_PROG_LOAD.
The bpf_prog_alloc_id() is done after bpf_prog_select_runtime()
because the jit process may have allocated a new prog. Hence,
we need to ensure the value of pointer 'prog' will not be changed
any more before storing the prog to the prog_idr.
After bpf_prog_select_runtime(), the prog is read-only. Hence,
the id is stored in 'struct bpf_prog_aux'.

The bug is that the name of the icq_cache is 6 characters longer than

There is need to instruct the HW offloaded path to push certain matched

new TRAP control action to TC.
For kernel datapath, this action does not make much sense. So with the
same logic as in HW, new TRAP behaves similar to STOLEN. The skb is just
dropped in the datapath (and virtually ejected to an upper level, which
does not exist in case of kernel).

rxrpc: Support service upgrade
Here's a set of patches that allow AF_RXRPC to support the AuriStor service
upgrade facility. This allows the server to change the service ID
requested to an upgraded service if the client requests it upon the
initiation of a connection.
This is used by the AuriStor AFS-compatible servers to implement IPv6
handling and improved facilities by providing improved volume location,
volume, protection, file and cache management services. Note that certain
parts of the AFS protocol carry hard-coded IPv4 addresses.
The reason AuriStor does it this way is that probing the improved service
ID first will not incur an ABORT or any other response on some servers if
the server is not listening on it - and so one have to employ a timeout.
This is implemented in the server by allowing an AF_RXRPC server to call
bind() twice on a socket to allow it to listen on two service IDs and then
call setsockopt() to instruct the server to upgrade one into the other if
the client requests it (by setting userStatus to 1 on the first DATA packet
on a connection). If the upgrade occurs, all further operations on that
connection are done with the new service ID. AF_RXRPC has to handle this
automatically as connections are not exposed to userspace.
Clients can request this facility by setting an RXRPC_UPGRADE_SERVICE
command in the sendmsg() control buffer and then observing the resultant
service ID in the msg_addr returned by recvmsg(). This should only be used
to probe the service. Clients should then use the returned service ID in
all subsequent communications with that server. Note that the kernel will
not retain this information should the connection expire from its cache.

As the V4L2 fwnode support will be required by a small minority of e.g.
ACPI based systems (the same might actually go for OF), make this a module
instead of embedding it in the videodev module.
