5e74396d8b PCI: kirin: Fix section mismatch warning
commit 6870b67350 upstream.

The PCI kirin driver compilation produces the following section mismatch
warning:

WARNING: vmlinux.o(.text+0x4758cc): Section mismatch in reference from
the function kirin_pcie_probe() to the function
.init.text:kirin_add_pcie_port()
The function kirin_pcie_probe() references
the function __init kirin_add_pcie_port().
This is often because kirin_pcie_probe lacks a __init
annotation or the annotation of kirin_add_pcie_port is wrong.

Remove '__init' from kirin_add_pcie_port() to fix it.

0d50f7b1e8 iommu/amd: Fix race in increase_address_space()
[ Upstream commit 754265bcab ]

After the conversion to lock-less dma-api call the
increase_address_space() function can be called without any
locking. Multiple CPUs could potentially race for increasing
the address space, leading to invalid domain->mode settings
and invalid page-tables. This has been happening in the wild
under high IO load and memory pressure.

Fix the race by locking this operation. The function is
called infrequently so that this does not introduce
a performance regression in the dma-api path again.

52f32e4aec iommu/amd: Flush old domains in kdump kernel
[ Upstream commit 36b7200f67 ]

When devices are attached to the amd_iommu in a kdump kernel, the old device
table entries (DTEs), which were copied from the crashed kernel, will be
overwritten with a new domain number.  When the new DTE is written, the IOMMU
is told to flush the DTE from its internal cache--but it is not told to flush
the translation cache entries for the old domain number.

Without this patch, AMD systems using the tg3 network driver fail when kdump
tries to save the vmcore to a network system, showing network timeouts and
(sometimes) IOMMU errors in the kernel log.

This patch will flush IOMMU translation cache entries for the old domain when
a DTE gets overwritten with a new domain number.

If a request_key authentication token key gets revoked, there's a window in

d73515a17c x86/hyper-v: Fix overflow bug in fill_gva_list()
[ Upstream commit 4030b4c585 ]

When the 'start' parameter is >=  0xFF000000 on 32-bit
systems, or >= 0xFFFFFFFF'FF000000 on 64-bit systems,
fill_gva_list() gets into an infinite loop.

With such inputs, 'cur' overflows after adding HV_TLB_FLUSH_UNIT
and always compares as less than end.  Memory is filled with
guest virtual addresses until the system crashes.

Fix this by never incrementing 'cur' to be larger than 'end'.

371357770c x86/uaccess: Don't leak the AC flags into __get_user() argument evaluation
[ Upstream commit 9b8bd476e7 ]

Identical to __put_user(); the __get_user() argument evalution will too
leak UBSAN crud into the __uaccess_begin() / __uaccess_end() region.
While uncommon this was observed to happen for:

where UBSAN added array bound checking.

83360eb798 net: aquantia: fix out of memory condition on rx side
[ Upstream commit be6cef69ba ]

On embedded environments with hard memory limits it is a normal although
rare case when skb can't be allocated on rx part under high traffic.

In such OOM cases napi_complete_done() was not called.
So the napi object became in an invalid state like it is "scheduled".
Kernel do not re-schedules the poll of that napi object.

Consequently, kernel can not remove that object the system hangs on
`ifconfig down` waiting for a poll.

We are fixing this by gracefully closing napi poll routine with correct
invocation of napi_complete_done.

This was reproduced with artificially failing the allocation of skb to
simulate an "out of memory" error case and check that traffic does
not get stuck.

d485c65853 tools/power x86_energy_perf_policy: Fix argument parsing
[ Upstream commit 0353148240 ]

The -w argument in x86_energy_perf_policy currently triggers an
unconditional segfault.

This is because the argument string reads: "+a:c:dD:E:e:f:m:M:rt:u:vw" and
yet the argument handler expects an argument.

When parse_optarg_string is called with a null argument, we then proceed to
crash in strncmp, not horribly friendly.

The man page describes -w as taking an argument, the long form
(--hwp-window) is correctly marked as taking a required argument, and the
code expects it.

As such, this patch simply marks the short form (-w) as requiring an
argument.

254b9b2971 tools/power x86_energy_perf_policy: Fix "uninitialized variable" warnings at -O2
[ Upstream commit adb8049097 ]

x86_energy_perf_policy first uses __get_cpuid() to check the maximum
CPUID level and exits if it is too low.  It then assumes that later
calls will succeed (which I think is architecturally guaranteed).  It
also assumes that CPUID works at all (which is not guaranteed on
x86_32).

If optimisations are enabled, gcc warns about potentially
uninitialized variables.  Fix this by adding an exit-on-error after
every call to __get_cpuid() instead of just checking the maximum
level.

7ec11cad3f perf/x86/amd/ibs: Fix sample bias for dispatched micro-ops
[ Upstream commit 0f4cd769c4 ]

When counting dispatched micro-ops with cnt_ctl=1, in order to prevent
sample bias, IBS hardware preloads the least significant 7 bits of
current count (IbsOpCurCnt) with random values, such that, after the
interrupt is handled and counting resumes, the next sample taken
will be slightly perturbed.

The current count bitfield is in the IBS execution control h/w register,
alongside the maximum count field.

Currently, the IBS driver writes that register with the maximum count,
leaving zeroes to fill the current count field, thereby overwriting
the random bits the hardware preloaded for itself.

Fix the driver to actually retain and carry those random bits from the
read of the IBS control register, through to its write, instead of
overwriting the lower current count bits with zeroes.

Tested with:

perf record -c 100001 -e ibs_op/cnt_ctl=1/pp -a -C 0 taskset -c 0 <workload>

Tested on Family 15h and 17h machines.

Machines prior to family 10h Rev. C don't have the RDWROPCNT capability,
and have the IbsOpCurCnt bitfield reserved, so this patch shouldn't
affect their operation.

It is unknown why commit db98c5faf8 ("perf/x86: Implement 64-bit
counter support for IBS") ignored the lower 4 bits of the IbsOpCurCnt
field; the number of preloaded random bits has always been 7, AFAICT.

c6d779fd81 usb: host: xhci-tegra: Set DMA mask correctly
[ Upstream commit 993cc87534 ]

The Falcon microcontroller that runs the XUSB firmware and which is
responsible for exposing the XHCI interface can address only 40 bits of
memory. Typically that's not a problem because Tegra devices don't have
enough system memory to exceed those 40 bits.

However, if the ARM SMMU is enable on Tegra186 and later, the addresses
passed to the XUSB controller can be anywhere in the 48-bit IOV address
space of the ARM SMMU. Since the DMA/IOMMU API starts allocating from
the top of the IOVA space, the Falcon microcontroller is not able to
load the firmware successfully.

Fix this by setting the DMA mask to 40 bits, which will force the DMA
API to map the buffer for the firmware to an IOVA that is addressable by
the Falcon.

9a74f799b9 kallsyms: Don't let kallsyms_lookup_size_offset() fail on retrieving the first symbol
[ Upstream commit 2a1a3fa0f2 ]

An arm64 kernel configured with

  CONFIG_KPROBES=y
  CONFIG_KALLSYMS=y
  # CONFIG_KALLSYMS_ALL is not set
  CONFIG_KALLSYMS_BASE_RELATIVE=y

reports the following kprobe failure:

  [    0.032677] kprobes: failed to populate blacklist: -22
  [    0.033376] Please take care of using kprobes.

It appears that kprobe fails to retrieve the symbol at address
0xffff000010081000, despite this symbol being in System.map:

  ffff000010081000 T __exception_text_start

This symbol is part of the first group of aliases in the
kallsyms_offsets array (symbol names generated using ugly hacks in
scripts/kallsyms.c):

  kallsyms_offsets:
          .long   0x1000 // do_undefinstr
          .long   0x1000 // efi_header_end
          .long   0x1000 // _stext
          .long   0x1000 // __exception_text_start
          .long   0x12b0 // do_cp15instr

Looking at the implementation of get_symbol_pos(), it returns the
lowest index for aliasing symbols. In this case, it return 0.

But kallsyms_lookup_size_offset() considers 0 as a failure, which
is obviously wrong (there is definitely a valid symbol living there).
In turn, the kprobe blacklisting stops abruptly, hence the original
error.

A CONFIG_KALLSYMS_ALL kernel wouldn't fail as there is always
some random symbols at the beginning of this array, which are never
looked up via kallsyms_lookup_size_offset.

Fix it by considering that get_symbol_pos() is always successful
(which is consistent with the other uses of this function).

> 'ioapic_dynirq_base' contains the virtual IRQ base number. Presently, it is
> updated to the end of hardware IRQ numbers but this is done only when IOAPIC
> configuration type is IOAPIC_DOMAIN_LEGACY or IOAPIC_DOMAIN_STRICT. There is

>
> See dtb_add_ioapic() in arch/x86/kernel/devicetree.c
>
> In case of IOAPIC_DOMAIN_DYNAMIC (DT/OF based system), 'ioapic_dynirq_base'
> remains to zero initialized value. This means that for OF based systems,
> virtual IRQ base will get set to zero.

Such systems will very likely not even boot.

For DT enabled machines ioapic_dynirq_base is irrelevant and not
updated, so simply map the IRQ base 1:1 instead.

688fdaa54a r8152: Set memory to all 0xFFs on failed reg reads
[ Upstream commit f53a7ad189 ]

get_registers() blindly copies the memory written to by the
usb_control_msg() call even if the underlying urb failed.

This could lead to junk register values being read by the driver, since
some indirect callers of get_registers() ignore the return values. One
example is:
  ocp_read_dword() ignores the return value of generic_ocp_read(), which
  calls get_registers().

So, emulate PCI "Master Abort" behavior by setting the buffer to all
0xFFs when usb_control_msg() fails.

This patch is copied from the r8152 driver (v2.12.0) published by
Realtek (www.realtek.com).

d9f79f0ace bpf: allow narrow loads of some sk_reuseport_md fields with offset > 0
[ Upstream commit 2c238177bd ]

test_select_reuseport fails on s390 due to verifier rejecting
test_select_reuseport_kern.o with the following message:

	; data_check.eth_protocol = reuse_md->eth_protocol;
	18: (69) r1 = *(u16 *)(r6 +22)
	invalid bpf_context access off=22 size=2

This is because on big-endian machines casts from __u32 to __u16 are
generated by referencing the respective variable as __u16 with an offset
of 2 (as opposed to 0 on little-endian machines).

The verifier already has all the infrastructure in place to allow such
accesses, it's just that they are not explicitly enabled for
eth_protocol field. Enable them for eth_protocol field by using
bpf_ctx_range instead of offsetof.

Ditto for ip_protocol, bind_inany and len, since they already allow
narrowing, and the same problem can arise when working with them.

7d4201ff9f batman-adv: Only read OGM2 tvlv_len after buffer len check
[ Upstream commit 0ff0f15a32 ]

Multiple batadv_ogm2_packet can be stored in an skbuff. The functions
batadv_v_ogm_send_to_if() uses batadv_v_ogm_aggr_packet() to check if there
is another additional batadv_ogm2_packet in the skb or not before they
continue processing the packet.

The length for such an OGM2 is BATADV_OGM2_HLEN +
batadv_ogm2_packet->tvlv_len. The check must first check that at least
BATADV_OGM2_HLEN bytes are available before it accesses tvlv_len (which is
part of the header. Otherwise it might try read outside of the currently
available skbuff to get the content of tvlv_len.

while it should pass. Even if bounds check would have passed, the code
that follows uses 64-bit index to compute prog array offset.

Fix by using clrj instead of clgrj for comparing index with array size,

code path would have been a no-op because of the clock validity checks
within sysc_unprepare(), but let's just simplify the cleanup path by
returning the error directly.

While at this, also fix the cleanup path for a sysc_init_resets()
failure which is executed after the clocks are prepared.

1a85d5819a ARM: OMAP1: ams-delta-fiq: Fix missing irq_ack
[ Upstream commit fa8397e45c ]

Non-serio path of Amstrad Delta FIQ deferred handler depended on
irq_ack() method provided by OMAP GPIO driver.  That method has been
removed by commit 693de831c6 ("gpio: omap: remove irq_ack method").
Remove useless code from the deferred handler and reimplement the
missing operation inside the base FIQ handler.

Should another dependency - irq_unmask() - be ever removed from the OMAP
GPIO driver, WARN once if missing.

a8919f8d35 ARM: dts: dra74x: Fix iodelay configuration for mmc3
[ Upstream commit 07f9a8be66 ]

According to the latest am572x[1] and dra74x[2] data manuals, mmc3
default, hs, sdr12 and sdr25 modes use iodelay values given in
MMC3_MANUAL1. Set the MODE_SELECT bit for these so that manual mode is
selected and correct iodelay values can be configured.

2ff2bd2c55 ARM: OMAP2+: Fix omap4 errata warning on other SoCs
[ Upstream commit 45da5e09dd ]

We have errata i688 workaround produce warnings on SoCs other than
omap4 and omap5:

omap4_sram_init:Unable to allocate sram needed to handle errata I688
omap4_sram_init:Unable to get sram pool needed to handle errata I688

This is happening because there is no ti,omap4-mpu node, or no SRAM
to configure for the other SoCs, so let's remove the warning based
on the SoC revision checks.

As nobody has complained it seems that the other SoC variants do not
need this workaround.
