      net: macb: Align the dma and coherent dma masks · f0c3ec67
      Marc St-Amand authored 
      [ Upstream commit 37f78606

 ]

Single page and coherent memory blocks can use different DMA masks
when the macb accesses physical memory directly. The kernel is clever
enough to allocate pages that fit into the requested address width.

When using the ARM SMMU, the DMA mask must be the same for single
pages and big coherent memory blocks. Otherwise the translation
tables turn into one big mess.

  [   74.959909] macb ff0e0000.ethernet eth0: DMA bus error: HRESP not OK
  [   74.959989] arm-smmu fd800000.smmu: Unhandled context fault: fsr=0x402, iova=0x3165687460, fsynr=0x20001, cbfrsynra=0x877, cb=1

Since using the same DMA mask does not hurt direct 1:1 physical
memory mappings, this commit always aligns DMA and coherent masks.

      tracing: Fix tp_printk option related with tp_printk_stop_on_boot · aba99eb4
      JaeSang Yoo authored 
      [ Upstream commit 3203ce39 ]

The kernel parameter "tp_printk_stop_on_boot" starts with "tp_printk" which is
the same as another kernel parameter "tp_printk". If "tp_printk" setup is
called before the "tp_printk_stop_on_boot", it will override the latter
and keep it from being set.

This is similar to other kernel parameter issues, such as:
  Commit 745a600c ("um: console: Ignore console= option")
or init/do_mounts.c:45 (setup function of "ro" kernel param)

Fix it by checking for a "_" right after the "tp_printk" and if that
exists do not process the parameter.

      Zoltán Böszörményi authored 
      [ Upstream commit c8ea23d5

 ]

This device is a CF card, or possibly an SSD in CF form factor.
It supports NCQ and high speed DMA.

While it also advertises TRIM support, I/O errors are reported
when the discard mount option fstrim is used. TRIM also fails
when disabling NCQ and not just as an NCQ command.

TRIM must be disabled for this device.

      mtd: rawnand: brcmnand: Fixed incorrect sub-page ECC status · bad3e6c6
      david regan authored 
      [ Upstream commit 36415a79 ]

The brcmnand driver contains a bug in which if a page (example 2k byte)
is read from the parallel/ONFI NAND and within that page a subpage (512
byte) has correctable errors which is followed by a subpage with
uncorrectable errors, the page read will return the wrong status of
correctable (as opposed to the actual status of uncorrectable.)

The bug is in function brcmnand_read_by_pio where there is a check for
uncorrectable bits which will be preempted if a previous status for
correctable bits is detected.

The fix is to stop checking for bad bits only if we already have a bad
bits status.

We have been living dangerously, at the mercy of malicious users,
abusing TC_ACT_REPEAT, as shown by this syzpot report [1].

Add an arbitrary limit (32) to the number of times an action can
return TC_ACT_REPEAT.

v2: switch the limit to 32 instead of 10.
    Use net_warn_ratelimited() instead of pr_err_once().

      EDAC: Fix calculation of returned address and next offset in edac_align_ptr() · 4feddbe5
      Eliav Farber authored 
      commit f8efca92 upstream.

Do alignment logic properly and use the "ptr" local variable for
calculating the remainder of the alignment.

This became an issue because struct edac_mc_layer has a size that is not
zero modulo eight, and the next offset that was prepared for the private
data was unaligned, causing an alignment exception.

The patch in Fixes: which broke this actually wanted to "what we
actually care about is the alignment of the actual pointer that's about
to be returned." But it didn't check that alignment.

Use the correct variable "ptr" for that.

a symbolic link on an NFS mount to a directory on another NFS does not

      powerpc/lib/sstep: fix 'ptesync' build error · 16e919d0
      Anders Roxell authored 
      commit fe663df7 upstream.

Building tinyconfig with gcc (Debian 11.2.0-16) and assembler (Debian
2.37.90.20220207) the following build error shows up:

  {standard input}: Assembler messages:
  {standard input}:2088: Error: unrecognized opcode: `ptesync'
  make[3]: *** [/builds/linux/scripts/Makefile.build:287: arch/powerpc/lib/sstep.o] Error 1

Add the 'ifdef CONFIG_PPC64' around the 'ptesync' in function
'emulate_update_regs()' to like it is in 'analyse_instr()'. Since it looks like
it got dropped inadvertently by commit 3cdfcbfd ("powerpc: Change
analyse_instr so it doesn't modify *regs").

A key detail is that analyse_instr() will never recognise lwsync or
ptesync on 32-bit (because of the existing ifdef), and as a result
emulate_update_regs() should never be called with an op specifying
either of those on 32-bit. So removing them from emulate_update_regs()
should be a nop in terms of runtime behaviour.

Fixes: 3cdfcbfd

When writing out a stereo control we discard the change notification from

to the second channel. Ensure that we report a change if either channel

      Takashi Iwai authored 
      commit 6317f744 upstream.

The forced probe mask via probe_mask 0x100 bit doesn't work any longer
as expected since the bus init code was moved and it's clearing the
codec_mask value that was set beforehand.  This patch fixes the
long-time regression by moving the check_probe_mask() call.

      drop_monitor: fix data-race in dropmon_net_event / trace_napi_poll_hit · cbc0e2a0
      Eric Dumazet authored 
      commit dcd54265 upstream.

trace_napi_poll_hit() is reading stat->dev while another thread can write
on it from dropmon_net_event()

Use READ_ONCE()/WRITE_ONCE() here, RCU rules are properly enforced already,
we only have to take care of load/store tearing.

      ping: fix the dif and sdif check in ping_lookup · 5a5c871b
      Xin Long authored 
      commit 35a79e64 upstream.

When 'ping' changes to use PING socket instead of RAW socket by:

   # sysctl -w net.ipv4.ping_group_range="0 100"

There is another regression caused when matching sk_bound_dev_if
and dif, RAW socket is using inet_iif() while PING socket lookup
is using skb->dev->ifindex, the cmd below fails due to this:

  # ip link add dummy0 type dummy
  # ip link set dummy0 up
  # ip addr add 192.168.111.1/24 dev dummy0
  # ping -I dummy0 192.168.111.1 -c1

The issue was also reported on:

  https://github.com/iputils/iputils/issues/104

But fixed in iputils in a wrong way by not binding to device when
destination IP is on device, and it will cause some of kselftests
to fail, as Jianlin noticed.

This patch is to use inet(6)_iif and inet(6)_sdif to get dif and
sdif for PING socket, and keep consistent with RAW socket.

      Miquel Raynal authored 
      commit bdc120a2 upstream.

These periods are expressed in time units (microseconds) while 40 and 12
are the number of symbol durations these periods will last. We need to
multiply them both with the symbol_duration in order to get these
values in microseconds.

      Johannes Berg authored 
      commit 4c29c1e2 upstream.

If we run into this error path, we shouldn't unlock the mutex
since it's not locked since. Fix this in the gen2 code as well.
