Return EPROBE_DEFER if Regulator returns EPROBE_DEFER
If the Flexcan driver is built into kernel and a regulator is used to
enable the CAN transceiver, the Flexcan driver may not use the regulator.
When initializing the Flexcan device with a regulator defined in the device
tree, but not initialized, the regulator subsystem returns EPROBE_DEFER, hence
the Flexcan init fails.
The solution for this is to return EPROBE_DEFER if regulator is not initialized
and wait until the regulator is initialized.

Current driver code arbitrarily assumes a max outstanding tx
value of 16 parallel transmissions. Meanwhile, the device
firmware provides its actual maximum inside its reply to the
CMD_GET_SOFTWARE_INFO message.
Under heavy tx traffic, if the interleaved transmissions count
increases above the limit reported by firmware, the firmware
breaks up badly, reports a massive list of internal errors, and
the candump traces hardly matches the actual frames sent and
received.
On the other hand, in certain models, the firmware can support
up to 48 tx URBs instead of just 16, increasing the driver
throughput by two-fold and reducing the possibility of -ENOBUFs.
Thus dynamically set the driver's max tx URBs value according
to firmware replies.

Transmission of an AP beacon does not call the TX interrupt service routine,
which usually does the cleanup. Instead, cleanup is handled in a tasklet
completion routine. Unfortunately, this routine has a serious bug in that it does
not release the DMA mapping before it frees the skb, thus one IOMMU mapping is
leaked for each beacon. The test system failed with no free IOMMU mapping slots
approximately one hour after hostapd was used to start an AP.
This issue was reported and tested at https://github.com/lwfinger/rtlwifi_new/issues/30.

When the device is powered up, some (older) firmware versions fail to work
properly if we send commands before the boot is complete (everything is OK
when the device is hot-plugged). The firmware indicates its ready status by
putting the link up.
Newer firmwares delay the first command so they don't suffer from this problem.
They also report the link being always up.
Wait for firmware to become ready (link up) before sending any commands and/or
data.
This also allows lowering CMD_TIMEOUT value to a reasonable time.
Tested with 4.1.0.9 (old) and 4.1.0.30 (new) firmware versions.

Currently 'Playback Volume' is the correct way to express an analogue
volume control. However, this control name has initialisation defaults
applied when using 'alsactl restore' and in some cases this is not
appropriate. An example would be a control that has a selection of
0db and -6dB of gain that is intended to set the fullscale ouput
voltage of a DAC. The TI pcm512x family of DAcs have such a control.
In this case the device/driver reset defaults are preferred.

- mm switching fix where the kernel pgd ends up in the user TTBR0 after
returning from an EFI run-time services call
- fix __GFP_ZERO handling for atomic pool and CMA DMA allocations (the
generic code does get the gfp flags, so it's left with the arch code
to memzero accordingly)

Pull ARM fixes from Russell King:
"Another few ARM fixes. Fabrice fixed the L2 cache DT parsing to allow
prefetch configuration to be specified even when the cache size
parsing fails.
Laura noticed that the setting of page attributes wasn't working for
modules due to is_module_addr() always returning false.
Marc Gonzalez (aka Mason) noticed a potential latent bug with the way
we read one of the CPUID registers (where we could attempt to read a
non-present CPUID register which may fault.)
I've fixed an issue where 32-bit DMA masks were failing with memory
which extended to the top of physical address space, and I've also
added debugging output of the page tables when we hit a data access
exception which we don't specifically handle - prompted by the lack of
information in a bug report"

For example, when mount opt is redundently specified
(e.g., "user=A,user=B,user=C"), kernel kept allocating new key/val
with kstrdup() and overwrite previous ptr (to be freed).
Althouhg mount.cifs in userspace performs a bit of sanitization
(e.g., forcing one user option), current implementation is not
robust. Other options such as iocharset and domainanme are similarly
vulnerable.

Under intermittent network outages, find_writable_file() is susceptible
to the following race condition, which results in a user-after-free in
the cifs_writepages code-path:
Thread 1 Thread 2
======== ========
inv_file = NULL
refind = 0
spin_lock(&cifs_file_list_lock)
// invalidHandle found on openFileList
inv_file = open_file
// inv_file->count currently 1
cifsFileInfo_get(inv_file)
// inv_file->count = 2
spin_unlock(&cifs_file_list_lock);
cifs_reopen_file() cifs_close()
// fails (rc != 0) ->cifsFileInfo_put()
spin_lock(&cifs_file_list_lock)
// inv_file->count = 1
spin_unlock(&cifs_file_list_lock)
spin_lock(&cifs_file_list_lock);
list_move_tail(&inv_file->flist,
&cifs_inode->openFileList);
spin_unlock(&cifs_file_list_lock);
cifsFileInfo_put(inv_file);
->spin_lock(&cifs_file_list_lock)
// inv_file->count = 0
list_del(&cifs_file->flist);
// cleanup!!
kfree(cifs_file);
spin_unlock(&cifs_file_list_lock);
spin_lock(&cifs_file_list_lock);
++refind;
// refind = 1
goto refind_writable;
At this point we loop back through with an invalid inv_file pointer
and a refind value of 1. On second pass, inv_file is not overwritten on
openFileList traversal, and is subsequently dereferenced.

While attempting to clone a file on a samba server, we receive a
STATUS_INVALID_DEVICE_REQUEST. This is mapped to -EOPNOTSUPP which
isn't handled in smb2_clone_range(). We end up looping in the while loop
making same call to the samba server over and over again.
The proposed fix is to exit and return the error value when encountered
with an unhandled error.

If ->run() fails, it can either free the data structures it
allocated, or leave that task to ->free() which will be called
on failures.
However:
md.c calls ->free() even if ->private_data is NULL, which
causes problems in some personalities.
raid0.c frees the data, but doesn't clear ->private_data,
which will become a problem when we fix md.c
So better fix both these issues at once.

Commit db31c55a6f (net: clamp ->msg_namelen instead of returning an
error) introduced the clamping of msg_namelen when the unsigned value
was larger than sizeof(struct sockaddr_storage). This caused a
msg_namelen of -1 to be valid. The native code was subsequently fixed by
commit dbb490b965 (net: socket: error on a negative msg_namelen).
In addition, the native code sets msg_namelen to 0 when msg_name is
NULL. This was done in commit (6a2a2b3ae0 net:socket: set msg_namelen
to 0 if msg_name is passed as NULL in msghdr struct from userland) and
subsequently updated by 08adb7dabd (fold verify_iovec() into
copy_msghdr_from_user()).
This patch brings the get_compat_msghdr() in line with
copy_msghdr_from_user().

Some pins are used for controlling the LED with the VREF value.
This patch changes the power behavior of such pins to be constantly
up. A new state, pin_fixed, is introduced to nid_path to indicate
that the path contains the fixed pin. This improves also the
readability a bit for other static routes, too.
Then a helper function snd_hda_gen_fix_pin_power() is called from the
codec driver for such fixed pins, and it will create fake paths
containing only these pins with pin_fixed=1 flag.

====================
be2net: patch set
Hi David, this patch set includes 3 bug fixes to the be2net driver.
Patch 1 fixes a vlan isolation issue with VFs. When a VF is placed in
promiscous mode, it could receive packets belonging to any vlan, as
the PF driver grants vlan promisc capability to VFs. The PF
driver now disables the vlan promisc capability for VFs to fix this
problem.
Patch 2 fixes the call to MODIFY_EQ_DELAY FW cmd to not include more
than 8 EQs per cmd. The FW is not capable of handling more than 8 EQs
per cmd.
Patch 3 fixes an EEH error detection issue. On Power platforms,
when an EEH error occurs, the slot disconnect state is more reliably
detected via an MMIO read compared to a config read. So, the error
register reads that occur every second are now done via MMIO.
Pls apply this patch set to the "net" tree. Thanks!
====================

When an EEH error occurs, the device/slot is disconnected. This condition
is more reliably detected (i.e., returns all ones) with an MMIO read rather
than a config read -- especially on power platforms.
Hence, this patch fixes EEH error detection by replacing config reads with
MMIO reads for reading the error registers. The error registers in
Skyhawk-R/BE2/BE3 are accessible both via the config space and the
PCICFG (BAR0) memory space.
