Netfilter fixes for net

The following patchset contains Netfilter fixes for net:

1) Out-of-bound access to packet data from the snmp nat helper,
   from Jann Horn.

2) ICMP(v6) error packets are set as related traffic by conntrack,
   update protocol number before calling nf_nat_ipv4_manip_pkt()
   to use ICMP(v6) rather than the original protocol number,
   from Florian Westphal.

Mikulas Patocka ff0c129d3b dm crypt: don't overallocate the integrity tag space
bio_sectors() returns the value in the units of 512-byte sectors (no
matter what the real sector size of the device).  dm-crypt multiplies
bio_sectors() by on_disk_tag_size to calculate the space allocated for
integrity tags.  If dm-crypt is running with sector size larger than
512b, it allocates more data than is needed.

Device Mapper trims the extra space when passing the bio to
dm-integrity, so this bug didn't result in any visible misbehavior.
But it must be fixed to avoid wasteful memory allocation for the block
integrity payload.

Florian Westphal 8303b7e8f0 netfilter: nat: fix spurious connection timeouts
Sander Eikelenboom bisected a NAT related regression down
to the l4proto->manip_pkt indirection removal.

I forgot that ICMP(v6) errors (e.g. PKTTOOBIG) can be set as related
to the existing conntrack entry.

Therefore, when passing the skb to nf_nat_ipv4/6_manip_pkt(), that
ended up calling the wrong l4 manip function, as tuple->dst.protonum
is the original flows l4 protocol (TCP, UDP, etc).

Set the dst protocol field to ICMP(v6), we already have a private copy
of the tuple due to the inversion of src/dst.

Jann Horn c4c07b4d6f netfilter: nf_nat_snmp_basic: add missing length checks in ASN.1 cbs
The generic ASN.1 decoder infrastructure doesn't guarantee that callbacks
will get as much data as they expect; callbacks have to check the `datalen`
parameter before looking at `data`. Make sure that snmp_version() and
snmp_helper() don't read/write beyond the end of the packet data.

(Also move the assignment to `pdata` down below the check to make it clear
that it isn't necessarily a pointer we can use before the `datalen` check.)

Ilan Peer 6157ca0d6b mac80211: Fix Tx aggregation session tear down with ITXQs
When mac80211 requests the low level driver to stop an ongoing
Tx aggregation, the low level driver is expected to call
ieee80211_stop_tx_ba_cb_irqsafe() to indicate that it is ready
to stop the session. The callback in turn schedules a worker
to complete the session tear down, which in turn also handles
the relevant state for the intermediate Tx queue.

However, as this flow in asynchronous, the intermediate queue
should be stopped and not continue servicing frames, as in
such a case frames that are dequeued would be marked as part
of an aggregation, although the aggregation is already been
stopped.

Fix this by stopping the intermediate Tx queue, before
calling the low level driver to stop the Tx aggregation.

Sergei Trofimovich 491af60ffb alpha: fix page fault handling for r16-r18 targets
Fix page fault handling code to fixup r16-r18 registers.
Before the patch code had off-by-two registers bug.
This bug caused overwriting of ps,pc,gp registers instead
of fixing intended r16,r17,r18 (see `struct pt_regs`).

More details:

Initially Dmitry noticed a kernel bug as a failure
on strace test suite. Test passes unmapped userspace
pointer to io_submit:

```c
    #include <err.h>
    #include <unistd.h>
    #include <sys/mman.h>
    #include <asm/unistd.h>
    int main(void)
    {
        unsigned long ctx = 0;
        if (syscall(__NR_io_setup, 1, &ctx))
            err(1, "io_setup");
        const size_t page_size = sysconf(_SC_PAGESIZE);
        const size_t size = page_size * 2;
        void *ptr = mmap(NULL, size, PROT_READ | PROT_WRITE,
                         MAP_PRIVATE | MAP_ANONYMOUS, -1, 0);
        if (MAP_FAILED == ptr)
            err(1, "mmap(%zu)", size);
        if (munmap(ptr, size))
            err(1, "munmap");
        syscall(__NR_io_submit, ctx, 1, ptr + page_size);
        syscall(__NR_io_destroy, ctx);
        return 0;
    }
```

Running this test causes kernel to crash when handling page fault:

```

    a3 = 00000200001ac260  a4 = 00000200001ac1e8  a5 = 0000000000000001
    t8 = 0000000000000008  t9 = 000000011f8bce30  t10= 00000200001ac440
    t11= 0000000000000000  pv = fffffc00006fd320  at = 0000000000000000
    gp = 0000000000000000  sp = 00000000265fd174
    Disabling lock debugging due to kernel taint
    Trace:
    [<fffffc0000311404>] entSys+0xa4/0xc0
```

Here `gp` has invalid value. `gp is s overwritten by a fixup for the
following page fault handler in `io_submit` syscall handler:

```
    __se_sys_io_submit
    ...
        ldq     a1,0(t1)
        bne     t0,4280 <__se_sys_io_submit+0x180>
```

After a page fault `t0` should contain -EFALUT and `a1` is 0.
Instead `gp` was overwritten in place of `a1`.

This happens due to a off-by-two bug in `dpf_reg()` for `r16-r18`
(aka `a0-a2`).

I think the bug went unnoticed for a long time as `gp` is one
of scratch registers. Any kernel function call would re-calculate `gp`.

Dmitry tracked down the bug origin back to 2.1.32 kernel version
where trap_a{0,1,2} fields were inserted into struct pt_regs.
And even before that `dpf_reg()` contained off-by-one error.

Meelis Roos bfc9136824 alpha: Fix Eiger NR_IRQS to 128
Eiger machine vector definition has nr_irqs 128, and working 2.6.26
boot shows SCSI getting IRQ-s 64 and 65. Current kernel boot fails
because Symbios SCSI fails to request IRQ-s and does not find the disks.
It has been broken at least since 3.18 - the earliest I could test with
my gcc-5.

The headers have moved around and possibly another order of defines has
worked in the past - but since 128 seems to be correct and used, fix
arch/alpha/include/asm/irq.h to have NR_IRQS=128 for Eiger.

This fixes 4.19-rc7 boot on my Force Flexor A264 (Eiger subarch).

Juergen Gross 20e55bc17d x86/mm: Make set_pmd_at() paravirt aware
set_pmd_at() calls native_set_pmd() unconditionally on x86. This was
fine as long as only huge page entries were written via set_pmd_at(),
as Xen pv guests don't support those.

Commit 2c91bd4a4e ("mm: speed up mremap by 20x on large regions")
introduced a usage of set_pmd_at() possible on pv guests, leading to
failures like:

BUG: unable to handle kernel paging request at ffff888023e26778
#PF error: [PROT] [WRITE]
RIP: e030:move_page_tables+0x7c1/0xae0

Make set_pmd_at() paravirt aware by just letting it use set_pmd().

Lorenzo Bianconi c09551c6ff net: ipv4: use a dedicated counter for icmp_v4 redirect packets
According to the algorithm described in the comment block at the
beginning of ip_rt_send_redirect, the host should try to send
'ip_rt_redirect_number' ICMP redirect packets with an exponential
backoff and then stop sending them at all assuming that the destination
ignores redirects.
If the device has previously sent some ICMP error packets that are
rate-limited (e.g TTL expired) and continues to receive traffic,
the redirect packets will never be transmitted. This happens since
peer->rate_tokens will be typically greater than 'ip_rt_redirect_number'
and so it will never be reset even if the redirect silence timeout
(ip_rt_redirect_silence) has elapsed without receiving any packet
requiring redirects.

Fix it by using a dedicated counter for the number of ICMP redirect
packets that has been sent by the host

I have not been able to identify a given commit that introduced the
issue since ip_rt_send_redirect implements the same rate-limiting
algorithm from commit 1da177e4c3 ("Linux-2.6.12-rc2")

Linus Torvalds 46c291e277 ARM: SoC fixes for linux-5.0
This is a bit larger than normal, as we had not managed to send out
 a pull request before traveling for a week without my signing key.
 
 There are multiple code fixes for older bugs, all of which should
 get backported into stable kernels:
 
 - tango: one fix for multiplatform configurations broken on other
   platforms when tango is enabled
 - arm_scmi: device unregistration fix
 - iop32x: fix kernel oops from extraneous __init annotation
 - pxa: remove a double kfree
 - fsl qbman: close an interrupt clearing race
 
 The rest is the usual collection of smaller fixes for device tree
 files, on the renesas, allwinner, meson, omap, davinci, qualcomm
 and imx platforms. Some of these are for compile-time warnings,
 most are for board specific functionality that fails to work
 because of incorrect settings.

   - iop32x: fix kernel oops from extraneous __init annotation

   - pxa: remove a double kfree

  The rest is the usual collection of smaller fixes for device tree

  imx platforms.

  Some of these are for compile-time warnings, most are for board

Linus Torvalds 820828bffe powerpc fixes for 5.0 #4
Just two fixes, both going to stable.
 
 Our support for split pmd page table lock had a bug which could lead to a crash
 on mremap() when using the Radix MMU (Power9 only).
 
 A fix for the PAPR SCM driver (nvdimm) we added last release, which had a bug
 where we might mis-handle a hypervisor response leading to us failing to attach
 the memory region.

Russell King b5bfc21af5 net: sfp: do not probe SFP module before we're attached
When we probe a SFP module, we expect to be able to call the upstream
device's module_insert() function so that the upstream link can be
configured.  However, when the upstream device is delayed, we currently
may end up probing the module before the upstream device is available,
and lose the module_insert() call.

Avoid this by holding off probing the module until the SFP bus is
properly connected to both the SFP socket driver and the upstream
driver.
