commit abfed87e2a12bd246047d78c01d81eb9529f1d06 upstream.
This is used by code that doesn't need CONFIG_CRYPTO, so move this into
lib/ with a Kconfig option so that it can be selected by whatever needs
it.
This fixes a linker error Zheng pointed out when
CRYPTO_MANAGER_DISABLE_TESTS!=y and CRYPTO=m:

[ Upstream commit 27071b5cbca59d8e8f8750c199a6cbf8c9799963 ]
Even though the DW I2C controller reference clock source is requested by
the method devm_clk_get() with non-optional clock requirement the way the
clock handler is used afterwards has a pure optional clock semantic
(though in some circumstances we can get a warning about the clock missing
printed in the system console). There is no point in reimplementing that
functionality seeing the kernel clock framework already supports the
optional interface from scratch. Thus let's convert the platform driver to
using it.
Note by providing this commit we get to fix two problems. The first one
was introduced in commit c62ebb3d5f0d ("i2c: designware: Add support for
an interface clock"). It causes not having the interface clock (pclk)
enabled/disabled in case if the reference clock isn't provided. The second
problem was first introduced in commit b33af11de236 ("i2c: designware: Do
not require clock when SSCN and FFCN are provided"). Since that
modification the deferred probe procedure has been unsupported in case if
the interface clock isn't ready.

[ Upstream commit a6253579977e4c6f7818eeb05bf2bc65678a7187 ]
Sometimes it is necessary to use a PLT entry to call an ftrace
trampoline. This is handled by ftrace_make_call() and ftrace_make_nop(),
with each having *almost* identical logic, but this is not handled by
ftrace_modify_call() since its introduction in commit:
3b23e4991fb66f6d ("arm64: implement ftrace with regs")
Due to this, if we ever were to call ftrace_modify_call() for a callsite
which requires a PLT entry for a trampoline, then either:
a) If the old addr requires a trampoline, ftrace_modify_call() will use
an out-of-range address to generate the 'old' branch instruction.
This will result in warnings from aarch64_insn_gen_branch_imm() and
ftrace_modify_code(), and no instructions will be modified. As
ftrace_modify_call() will return an error, this will result in
subsequent internal ftrace errors.
b) If the old addr does not require a trampoline, but the new addr does,
ftrace_modify_call() will use an out-of-range address to generate the
'new' branch instruction. This will result in warnings from
aarch64_insn_gen_branch_imm(), and ftrace_modify_code() will replace
the 'old' branch with a BRK. This will result in a kernel panic when
this BRK is later executed.
Practically speaking, case (a) is vastly more likely than case (b), and
typically this will result in internal ftrace errors that don't
necessarily affect the rest of the system. This can be demonstrated with
an out-of-tree test module which triggers ftrace_modify_call(), e.g.

We can solve this by consistently determining whether to use a PLT entry
for an address.
Note that since (the earlier) commit:
f1a54ae9af0da4d7 ("arm64: module/ftrace: intialize PLT at load time")
... we can consistently determine the PLT address that a given callsite
will use, and therefore ftrace_make_nop() does not need to skip
validation when a PLT is in use.
This patch factors the existing logic out of ftrace_make_call() and
ftrace_make_nop() into a common ftrace_find_callable_addr() helper
function, which is used by ftrace_make_call(), ftrace_make_nop(), and
ftrace_modify_call(). In ftrace_make_nop() the patching is consistently
validated by ftrace_modify_code() as we can always determine what the
old instruction should have been.

[ Upstream commit 3eefdf9d1e406f3da47470b2854347009ffcb6fa ]
The branch range checks in ftrace_make_call() and ftrace_make_nop() are
incorrect, erroneously permitting a forwards branch of 128M and
erroneously rejecting a backwards branch of 128M.
This is because both functions calculate the offset backwards,
calculating the offset *from* the target *to* the branch, rather than
the other way around as the later comparisons expect.
If an out-of-range branch were erroeously permitted, this would later be
rejected by aarch64_insn_gen_branch_imm() as branch_imm_common() checks
the bounds correctly, resulting in warnings and the placement of a BRK
instruction. Note that this can only happen for a forwards branch of
exactly 128M, and so the caller would need to be exactly 128M bytes
below the relevant ftrace trampoline.
If an in-range branch were erroeously rejected, then:
* For modules when CONFIG_ARM64_MODULE_PLTS=y, this would result in the
use of a PLT entry, which is benign.
Note that this is the common case, as this is selected by
CONFIG_RANDOMIZE_BASE (and therefore RANDOMIZE_MODULE_REGION_FULL),
which distributions typically seelct. This is also selected by
CONFIG_ARM64_ERRATUM_843419.
* For modules when CONFIG_ARM64_MODULE_PLTS=n, this would result in
internal ftrace failures.
* For core kernel text, this would result in internal ftrace failues.
Note that for this to happen, the kernel text would need to be at
least 128M bytes in size, and typical configurations are smaller tha
this.
Fix this by calculating the offset *from* the branch *to* the target in
both functions.

This patch replaces skb_recv_datagram() with an open-coded variant of it
releasing the socket lock before the __skb_wait_for_more_packets() call
and re-acquiring it after such call in order that other functions that
need socket lock could be executed.
what's more, the socket lock will be released only when recvmsg() will
block and that should produce nicer overall behavior.

Both RIF and ACL flow counters use a 24-bit SW-managed counter address to
communicate which counter they want to bind.
In a number of Spectrum FW releases, binding a RIF counter is broken and
slices the counter index to 16 bits. As a result, on Spectrum-2 and above,
no more than about 410 RIF counters can be effectively used. This

does not happen on Spectrum-1, because there are fewer counters available
overall and the counter index never exceeds 16 bits.)
Binding counters to ACLs does not have this issue. Therefore reorder the
counter allocation scheme so that RIF counters come first and therefore get
lower indices that are below the 16-bit barrier.

This commit changes the default Kconfig values of RANDOM_TRUST_CPU and
RANDOM_TRUST_BOOTLOADER to be Y by default. It does not change any
existing configs or change any kernel behavior. The reason for this is
several fold.
As background, I recently had an email thread with the kernel
maintainers of Fedora/RHEL, Debian, Ubuntu, Gentoo, Arch, NixOS, Alpine,
SUSE, and Void as recipients. I noted that some distros trust RDRAND,
some trust EFI, and some trust both, and I asked why or why not. There
wasn't really much of a "debate" but rather an interesting discussion of
what the historical reasons have been for this, and it came up that some
distros just missed the introduction of the bootloader Kconfig knob,
while another didn't want to enable it until there was a boot time
switch to turn it off for more concerned users (which has since been
added). The result of the rather uneventful discussion is that every
major Linux distro enables these two options by default.
While I didn't have really too strong of an opinion going into this
thread -- and I mostly wanted to learn what the distros' thinking was
one way or another -- ultimately I think their choice was a decent
enough one for a default option (which can be disabled at boot time).
I'll try to summarize the pros and cons:
Pros:
- The RNG machinery gets initialized super quickly, and there's no
messing around with subsequent blocking behavior.
- The bootloader mechanism is used by kexec in order for the prior
kernel to initialize the RNG of the next kernel, which increases
the entropy available to early boot daemons of the next kernel.
- Previous objections related to backdoors centered around
Dual_EC_DRBG-like kleptographic systems, in which observing some
amount of the output stream enables an adversary holding the right key
to determine the entire output stream.
This used to be a partially justified concern, because RDRAND output
was mixed into the output stream in varying ways, some of which may
have lacked pre-image resistance (e.g. XOR or an LFSR).
But this is no longer the case. Now, all usage of RDRAND and
bootloader seeds go through a cryptographic hash function. This means
that the CPU would have to compute a hash pre-image, which is not
considered to be feasible (otherwise the hash function would be
terribly broken).
- More generally, if the CPU is backdoored, the RNG is probably not the
realistic vector of choice for an attacker.
- These CPU or bootloader seeds are far from being the only source of
entropy. Rather, there is generally a pretty huge amount of entropy,
not all of which is credited, especially on CPUs that support
instructions like RDRAND. In other words, assuming RDRAND outputs all
zeros, an attacker would *still* have to accurately model every single
other entropy source also in use.
- The RNG now reseeds itself quite rapidly during boot, starting at 2
seconds, then 4, then 8, then 16, and so forth, so that other sources
of entropy get used without much delay.
- Paranoid users can set random.trust_{cpu,bootloader}=no in the kernel
command line, and paranoid system builders can set the Kconfig options
to N, so there's no reduction or restriction of optionality.
- It's a practical default.
- All the distros have it set this way. Microsoft and Apple trust it
too. Bandwagon.
Cons:
- RDRAND *could* still be backdoored with something like a fixed key or
limited space serial number seed or another indexable scheme like
that. (However, it's hard to imagine threat models where the CPU is
backdoored like this, yet people are still okay making *any*
computations with it or connecting it to networks, etc.)
- RDRAND *could* be defective, rather than backdoored, and produce
garbage that is in one way or another insufficient for crypto.
- Suggesting a *reduction* in paranoia, as this commit effectively does,
may cause some to question my personal integrity as a "security
person".
- Bootloader seeds and RDRAND are generally very difficult if not all
together impossible to audit.
Keep in mind that this doesn't actually change any behavior. This
is just a change in the default Kconfig value. The distros already are
shipping kernels that set things this way.
Ard made an additional argument in [1]:
We're at the mercy of firmware and micro-architecture anyway, given
that we are also relying on it to ensure that every instruction in
the kernel's executable image has been faithfully copied to memory,
and that the CPU implements those instructions as documented. So I
don't think firmware or ISA bugs related to RNGs deserve special
treatment - if they are broken, we should quirk around them like we
usually do. So enabling these by default is a step in the right
direction IMHO.
In [2], Phil pointed out that having this disabled masked a bug that CI
otherwise would have caught:
A clean 5.15.45 boots cleanly, whereas a downstream kernel shows the
static key warning (but it does go on to boot). The significant
difference is that our defconfigs set CONFIG_RANDOM_TRUST_BOOTLOADER=y
defining that on top of multi_v7_defconfig demonstrates the issue on
a clean 5.15.45. Conversely, not setting that option in a
downstream kernel build avoids the warning

Currently if the APB or Debounce clocks aren't yet ready to be requested
the DW GPIO driver will correctly handle that by deferring the probe
procedure, but the error is still printed to the system log. It needlessly
pollutes the log since there was no real error but a request to postpone
the clock request procedure since the clocks subsystem hasn't been fully
initialized yet. Let's fix that by using the dev_err_probe method to print
the APB/clock request error status. It will correctly handle the deferred
probe situation and print the error if it actually happens.

which seems to be because it doesn't track how the use (and
initialization) is bound by the 'do_bond' flag.
But admittedly that 'do_bond' usage is fairly complicated, and involves
passing it around as an argument to helper functions, so it's somewhat
understandable that gcc doesn't see how that all works.
This function could be rewritten to make the use of that tracker
variable more obviously safe, but for now I'm just adding the forced

and starts the RPI registration for DID 0x000001. The target then sends a

wm8962 3-001a: ASoC: error at soc_component_read_no_lock on wm8962.3-001a: -16
Once this error has occurred, the audio will not work again until rebooted.
Fix this by configuring SET_SYSTEM_SLEEP_PM_OPS.

As described in commit 02117b8ae9c0 ("f2fs: Set GF_NOFS in
read_cache_page_gfp while doing f2fs_quota_read"), we must not enter
filesystem reclaim while holding the dq_lock. Prevent this more generally
by using memalloc_nofs_save() while holding the lock.

In an unlikely (and probably wrong?) case that the 'ppi' parameter of
ata_host_alloc_pinfo() points to an array starting with a NULL pointer,
there's going to be a kernel oops as the 'pi' local variable won't get
reassigned from the initial value of NULL. Initialize 'pi' instead to
'&ata_dummy_port_info' to fix the possible kernel oops for good...

The minimum value for the PGA Volume is given as 0x1A, however the
values from there to 0x19 are all the same volume and this is not
represented in the TLV structure. The number of volumes given is correct
so this leads to all the volumes being shifted. Move the minimum value
up to 0x19 to fix this.

A couple of the SX volume controls specify 0x84 as the lowest volume
value, however the correct value from the datasheet is 0x44. The
datasheet don't include spaces in the value it displays as binary so
this was almost certainly just a typo reading 1000100.
