usb: gadget: u_ether: fix regression in setting fixed MAC address
In systemd systems setting a fixed MAC address through
the "dev_addr" module argument fails systematically.
When checking the MAC address after the interface is created
it always has the same but different MAC address to the one
supplied as argument.
This is partially caused by systemd which by default will
set an internally generated permanent MAC address for interfaces
that are marked as having a randomly generated address.
Commit 890d5b40908bfd1a ("usb: gadget: u_ether: fix race in
setting MAC address in setup phase") didn't take into account
the fact that the interface must be marked as having a set
MAC address when it's set as module argument.
Fixed by marking the interface with NET_ADDR_SET when
the "dev_addr" module argument is supplied.

usb: dwc3: gadget: Fix IN endpoint max packet size allocation
The current logic to assign the max packet limit for IN endpoints attempts
to take the default HW value and apply the optimal endpoint settings based
on it. However, if the default value reports a TxFIFO size large enough
for only one max packet, it will divide the value and assign a smaller ep
max packet limit.
For example, if the default TxFIFO size fits 1024B, current logic will
assign 1024/3 = 341B to ep max packet size. If function drivers attempt to
request for an endpoint with a wMaxPacketSize of 1024B (SS BULK max packet
size) then it will fail, as the gadget is unable to find an endpoint which
can fit the requested size.
Functionally, if the TxFIFO has enough space to fit one max packet, it will
be sufficient, at least when initializing the endpoints.

net: seg6: fix seg6_lookup_any_nexthop() to handle VRFs using flowi_l3mdev
Commit 40867d74c374 ("net: Add l3mdev index to flow struct and avoid oif
reset for port devices") adds a new entry (flowi_l3mdev) in the common
flow struct used for indicating the l3mdev index for later rule and
table matching.
The l3mdev_update_flow() has been adapted to properly set the
flowi_l3mdev based on the flowi_oif/flowi_iif. In fact, when a valid
flowi_iif is supplied to the l3mdev_update_flow(), this function can
update the flowi_l3mdev entry only if it has not yet been set (i.e., the
flowi_l3mdev entry is equal to 0).
The SRv6 End.DT6 behavior in VRF mode leverages a VRF device in order to
force the routing lookup into the associated routing table. This routing
operation is performed by seg6_lookup_any_nextop() preparing a flowi6
data structure used by ip6_route_input_lookup() which, in turn,
(indirectly) invokes l3mdev_update_flow().
However, seg6_lookup_any_nexthop() does not initialize the new
flowi_l3mdev entry which is filled with random garbage data. This
prevents l3mdev_update_flow() from properly updating the flowi_l3mdev
with the VRF index, and thus SRv6 End.DT6 (VRF mode)/DT46 behaviors are
broken.
This patch correctly initializes the flowi6 instance allocated and used
by seg6_lookup_any_nexhtop(). Specifically, the entire flowi6 instance
is wiped out: in case new entries are added to flowi/flowi6 (as happened
with the flowi_l3mdev entry), we should no longer have incorrectly
initialized values. As a result of this operation, the value of
flowi_l3mdev is also set to 0.
The proposed fix can be tested easily. Starting from the commit
referenced in the Fixes, selftests [1],[2] indicate that the SRv6
End.DT6 (VRF mode)/DT46 behaviors no longer work correctly. By applying
this patch, those behaviors are back to work properly again.

While randstruct was satisfied with using an open-coded "void *" offset

following complaint[1] from gcc v12:

Fix this by embedding a struct inode into struct netfs_i_context (which
should perhaps be renamed to struct netfs_inode). The struct inode
vfs_inode fields are then removed from the 9p, afs, ceph and cifs inode
structs and vfs_inode is then simply changed to "netfs.inode" in those
filesystems.
Further, rename netfs_i_context to netfs_inode, get rid of the
netfs_inode() function that converted a netfs_i_context pointer to an
inode pointer (that can now be done with &ctx->inode) and rename the
netfs_i_context() function to netfs_inode() (which is now a wrapper
around container_of()).
Kees suggested doing it with a pair structure[2] and a special
declarator to insert that into the network filesystem's inode
wrapper[3], but I think it's cleaner to embed it - and then it doesn't
matter if struct randomisation reorders things.
Dave Chinner suggested using a filesystem-specific VFS_I() function in
each filesystem to convert that filesystem's own inode wrapper struct
into the VFS inode struct[4].
Version #2:
- Fix a couple of missed name changes due to a disabled cifs option.
- Rename nfs_i_context to nfs_inode
- Use "netfs" instead of "nic" as the member name in per-fs inode wrapper
structs.

upsets the automated tools and it's generally bad practice anyway,

netfs: gcc-12: temporarily disable '-Wattribute-warning' for now
This is a pure band-aid so that I can continue merging stuff from people

and the reason is that netfs_i_context_init() is passed a 'struct inode'
pointer, and then it does
where that netfs_i_context() function just does pointer arithmetic on
the inode pointer, knowing that the netfs_i_context is laid out
immediately after it in memory.
This is all truly disgusting, since the whole "netfs_i_context is laid
out immediately after it in memory" is not actually remotely true in
general, but is just made to be that way for afs and ceph.
See for example fs/cifs/cifsglob.h:
struct cifsInodeInfo {
struct {
/* These must be contiguous */
struct inode vfs_inode; /* the VFS's inode record */
struct netfs_i_context netfs_ctx; /* Netfslib context */
};
[...]
and realize that this is all entirely wrong, and the pointer arithmetic
that netfs_i_context() is doing is also very very wrong and wouldn't
give the right answer if netfs_ctx had different alignment rules from a
'struct inode', for example).
Anyway, that's just a long-winded way to say "the gcc-12 warning is
actually quite reasonable, and our code happens to work but is pretty
disgusting".
This is getting fixed properly, but for now I made the mistake of
thinking "the week right after the merge window tends to be calm for me

It turns out gcc-12 has many other issues in this area, so this takes
that s390 warning disable logic, and turns it into a kernel build config

Part of the intent is that we can make this all much more targeted, and
use this conflig flag to disable it in only particular configurations
that cause problems, with the s390 case as an example:
select GCC12_NO_ARRAY_BOUNDS

gcc-12: disable '-Wdangling-pointer' warning for now
While the concept of checking for dangling pointers to local variables
at function exit is really interesting, the gcc-12 implementation is not
compatible with reality, and results in false positives.
For example, gcc sees us putting things on a local list head allocated
on the stack, which involves exactly those kinds of pointers to the
local stack entry:
In function ‘__list_add’,
inlined from ‘list_add_tail’ at include/linux/list.h:102:2,

74 | new->prev = prev;
| ~~~~~~~~~~^~~~~~
But then gcc - understandably - doesn't really understand the big
picture how the doubly linked list works, so doesn't see how we then end
up emptying said list head in a loop and the pointer we added has been
removed.
Gcc also complains about us (intentionally) using this as a way to store
a kind of fake stack trace, eg
drivers/acpi/acpica/utdebug.c:40:38: warning: storing the address of local variable ‘current_sp’ in ‘acpi_gbl_entry_stack_pointer’ [-Wdangling-pointer=]

which is entirely reasonable from a compiler standpoint, and we may want
to change those kinds of patterns, but not not.
So this is one of those "it would be lovely if the compiler were to
complain about us leaving dangling pointers to the stack", but not this
way.

iavf: Fix issue with MAC address of VF shown as zero

it simply resolves an undefined symbol to the first-encountered symbol.
This means that defining __weak arch-generic functions and then defining
arch-specific strong functions to override them in libkvm will not
always work.
More specifically, if we have:
lib/generic.c:
void __weak foo(void)

pr_info("weak\n");
}
void bar(void)
{
foo();
}
lib/x86_64/arch.c:

generic.o explicitly depend on arch.o (e.g. add function to arch.c that
is called directly from generic.c) it will print "strong". In other
words, it seems that the linker is free to throw out arch.o when linking

linker to lose the strong symbol.
One solution is to link libkvm.a with --whole-archive so that the linker
doesn't throw away object files it thinks are unnecessary. However that

x86_page_size is an enum used to communicate the desired page size with

few ways:
- The name suggests it encodes the size of the page rather than the

- In other places in x86_64/processor.c we just use a raw int to encode
the level.
Simplify this by adopting the kernel style of PG_LEVEL_XX enums and pass

to understand since these macros are very common in KVM MMU code.
Commit 74fd41ed16fd ("KVM: x86: nSVM: support PAUSE filtering when L0
doesn't intercept PAUSE") introduced passthrough support for nested pause
filtering, (when the host doesn't intercept PAUSE) (either disabled with
kvm module param, or disabled with '-overcommit cpu-pm=on')
Before this commit, L1 KVM didn't intercept PAUSE at all; afterwards,
the feature was exposed as supported by KVM cpuid unconditionally, thus
if L1 could try to use it even when the L0 KVM can't really support it.
In this case the fallback caused KVM to intercept each PAUSE instruction;
in some cases, such intercept can slow down the nested guest so much
that it can fail to boot. Instead, before the problematic commit KVM
was already setting both thresholds to 0 in vmcb02, but after the first
userspace VM exit shrink_ple_window was called and would reset the
pause_filter_count to the default value.
To fix this, change the fallback strategy - ignore the guest threshold
values, but use/update the host threshold values unless the guest
specifically requests disabling PAUSE filtering (either simple or
advanced).
Also fix a minor bug: on nested VM exit, when PAUSE filter counter
were copied back to vmcb01, a dirty bit was not set.

1. It is legal to issue an IPI request with APIC_DEST_NOSHORT
and a physical destination of 0xFF (or 0xFFFFFFFF in case of x2apic),
which must be treated as a broadcast destination.
Fix this by explicitly checking for it.
Also don’t use ‘index’ in this case as it gives no new information.
2. It is legal to issue a logical IPI request to more than one target.
Index field only provides index in physical id table of first
such target and therefore can't be used before we are sure
that only a single target was addressed.
Instead, parse the ICRL/ICRH, double check that a unicast interrupt
was requested, and use that info to figure out the physical id
of the target vCPU.
At that point there is no need to use the index field as well.
In addition to fixing the above issues, also skip the call to
kvm_apic_match_dest.
It is possible to do this now, because now as long as AVIC is not
inhibited, it is guaranteed that none of the vCPUs changed their
apic id from its default value.
This fixes boot of windows guest with AVIC enabled because it uses

powerpc/32: Fix overread/overwrite of thread_struct via ptrace
The ptrace PEEKUSR/POKEUSR (aka PEEKUSER/POKEUSER) API allows a process
to read/write registers of another process.
To get/set a register, the API takes an index into an imaginary address
space called the "USER area", where the registers of the process are
laid out in some fashion.
The kernel then maps that index to a particular register in its own data
structures and gets/sets the value.
The API only allows a single machine-word to be read/written at a time.
So 4 bytes on 32-bit kernels and 8 bytes on 64-bit kernels.
The way floating point registers (FPRs) are addressed is somewhat
complicated, because double precision float values are 64-bit even on
32-bit CPUs. That means on 32-bit kernels each FPR occupies two
word-sized locations in the USER area. On 64-bit kernels each FPR
occupies one word-sized location in the USER area.
Internally the kernel stores the FPRs in an array of u64s, or if VSX is
enabled, an array of pairs of u64s where one half of each pair stores
the FPR. Which half of the pair stores the FPR depends on the kernel's
endianness.
To handle the different layouts of the FPRs depending on VSX/no-VSX and
big/little endian, the TS_FPR() macro was introduced.
Unfortunately the TS_FPR() macro does not take into account the fact
that the addressing of each FPR differs between 32-bit and 64-bit
kernels. It just takes the index into the "USER area" passed from
userspace and indexes into the fp_state.fpr array.
On 32-bit there are 64 indexes that address FPRs, but only 32 entries in
the fp_state.fpr array, meaning the user can read/write 256 bytes past
the end of the array. Because the fp_state sits in the middle of the
thread_struct there are various fields than can be overwritten,
including some pointers. As such it may be exploitable.
It has also been observed to cause systems to hang or otherwise
misbehave when using gdbserver, and is probably the root cause of this
report which could not be easily reproduced:
https://lore.kernel.org/linuxppc-dev/dc38afe9-6b78-f3f5-666b-986939e40fc6@keymile.com/
Rather than trying to make the TS_FPR() macro even more complicated to
fix the bug, or add more macros, instead add a special-case for 32-bit
kernels. This is more obvious and hopefully avoids a similar bug
happening again in future.
Note that because 32-bit kernels never have VSX enabled the code doesn't
need to consider TS_FPRWIDTH/OFFSET at all. Add a BUILD_BUG_ON() to
ensure that 32-bit && VSX is never enabled.

or phy-connection-type property is specified in a DSA port node of the
device tree. The same commit caused a regression in rtl8365mb whereby
phylink would fail to connect, because the driver did not advertise
support for GMII for ports with internal PHY.
It should be noted that the aforementioned regression is not because the
blamed commit was incorrect: on the contrary, the blamed commit is
correcting the previous behaviour whereby unspecified phy-mode would
cause the internal interface mode to be PHY_INTERFACE_MODE_NA. The
rtl8365mb driver only worked by accident before because it _did_
advertise support for PHY_INTERFACE_MODE_NA, despite NA being reserved
for internal use by phylink. With one mistake fixed, the other was
exposed.
Commit a5dba0f207e5 ("net: dsa: rtl8365mb: add GMII as user port mode")
then introduced implicit support for GMII mode on ports with internal
PHY to allow a PHY connection for device trees where the phy-mode is not
explicitly set to "internal". At this point everything was working OK
again.
Subsequently, commit 6ff6064605e9 ("net: dsa: realtek: convert to
phylink_generic_validate()") broke this behaviour again by discarding
the usage of rtl8365mb_phy_mode_supported() - where this GMII support
was indicated - while switching to the new .phylink_get_caps API.
With the new API, rtl8365mb_phy_mode_supported() is no longer needed.
Remove it altogether and add back the GMII capability - this time to
rtl8365mb_phylink_get_caps() - so that the above default behaviour works
for ports with internal PHY again.
