[ Upstream commit 3890e3dea315f1a257d1b940a2a4e2fa16a7b095 ]
The macro "spi_register_driver" invokes the function
"__spi_register_driver()" which has a return type of int and can fail,
returning a negative value in such a case. This is currently ignored and
the init() function yields success even if the spi driver failed to
register.
Fix this by collecting the return value of "__spi_register_driver()" and
also unregister the uart driver in case of failure.

From: Greg Kroah-Hartman <[email protected]>
[ Upstream commit 7e79b38fe9a403b065ac5915465f620a8fb3de84 ]
The libertas driver was trying to register sysfs groups "by hand" which
causes them to be created _after_ the device is initialized and
announced to userspace, which causes races and can prevent userspace
tools from seeing the sysfs files correctly.
Fix this up by using the built-in sysfs_groups pointers in struct
net_device which were created for this very reason, fixing the race
condition, and properly allowing for any error that might have occured
to be handled properly.

Place a comment in hidma_mgmt_init explaining why success must
currently be assumed, due to the cleanup issue that would need to
be considered were this module ever to be unloadable or were this
platform_driver_register call ever to fail.

commit e0652f8bb44d6294eeeac06d703185357f25d50b upstream.
nfcmrvl_disconnect fails to free the hci_dev field in struct nci_dev.
Fix this by freeing hci_dev in nci_free_device.

[ Upstream commit c446f0d4702d316e1c6bf621f70e79678d28830a ]
Move hw->cfg.mode and hw->addr.mode assignments from hw->ci->cfg_mode
and hw->ci->addr_mode respectively, to be before the subsequent checks
for memory IO mode (and possible ioremap calls in this case).
Also introduce ioremap error checks at both locations. This allows
resources to be properly freed on ioremap failure, as when the caller
of setup_io then subsequently calls release_io via its error path,
release_io can now correctly determine the mode as it has been set
before the ioremap call.
Finally, refactor release_io function so that it will call
release_mem_region in the memory IO case, regardless of whether or not
hw->cfg.p/hw->addr.p are NULL. This means resources are then properly
released on failure.
This properly implements the original reverted commit (d721fe99f6ad)
from the University of Minnesota, whilst also implementing the ioremap
check for the hw->ci->cfg_mode if block as well.

This came up in the discussion of the requirements of qspinlock on an
architecture. OpenRISC uses qspinlock, but it was noticed that the
memmory barrier was not defined.
Peter defined it in the mail thread writing:
As near as I can tell this should do. The arch spec only lists
this one instruction and the text makes it sound like a completion
barrier.
This is correct so applying this patch.

[ Upstream commit 56f396146af278135c0ff958c79b5ee1bd22453d ]
Commit 391e2f25601e ("[SCSI] BusLogic: Port driver to 64-bit")
introduced a serious issue for 64-bit systems. With this commit,
64-bit kernel will enumerate 8*15 non-existing disks. This is caused
by the broken CCB structure. The change from u32 data to void *data
increased CCB length on 64-bit system, which introduced an extra 4
byte offset of the CDB. This leads to incorrect response to INQUIRY
commands during enumeration.
Fix disk enumeration failure by reverting the portion of the commit
above which switched the data pointer from u32 to void.

commit db825feefc6868896fed5e361787ba3bee2fd906 upstream.
Fix SFP and QSFP* EEPROM queries by setting i2c_address, offset and page
number correctly. For SFP set the following params:
- I2C address for offsets 0-255 is 0x50. For 256-511 - 0x51.
- Page number is zero.
- Offset is 0-255.
At the same time, QSFP* parameters are different:
- I2C address is always 0x50.
- Page number is not limited to zero.
- Offset is 0-255 for page zero and 128-255 for others.
To set parameters accordingly to cable used, implement function to query
module ID and implement respective helper functions to set parameters
correctly.

'bus->mii_bus' has been allocated with 'devm_mdiobus_alloc_size()' in the

Remove the incorrect 'mdiobus_free' in the error handling path of the
probe function and in remove function.

[ Upstream commit 84316ca4e100d8cbfccd9f774e23817cb2059868 ]
The skb_change_head() helper did not set "skb->mac_len", which is
problematic when it's used in combination with skb_redirect_peer().
Without it, redirecting a packet from a L3 device such as wireguard to
the veth peer device will cause skb->data to point to the middle of the
IP header on entry to tcp_v4_rcv() since the L2 header is not pulled
correctly due to mac_len=0.

[ Upstream commit 9b76eade16423ef06829cccfe3e100cfce31afcd ]
If Qdisc_ops->init() is failed, Qdisc_ops->reset() would be called.
When dsmark_init(Qdisc_ops->init()) is failed, it possibly doesn't
initialize dsmark_qdisc_data->q. But dsmark_reset(Qdisc_ops->reset())
uses dsmark_qdisc_data->q pointer wihtout any null checking.
So, panic would occur.
Test commands:
sysctl net.core.default_qdisc=dsmark -w
ip link add dummy0 type dummy
ip link add vw0 link dummy0 type virt_wifi
ip link set vw0 up
Splat looks like:

commit b7df21cf1b79ab7026f545e7bf837bd5750ac026 upstream.
It's not a good idea to append the frag skb to a skb's frag_list if
the frag_list already has skbs from elsewhere, such as this skb was
created by pskb_copy() where the frag_list was cloned (all the skbs
in it were skb_get'ed) and shared by multiple skbs.
However, the new appended frag skb should have been only seen by the
current skb. Otherwise, it will cause use after free crashes as this
appended frag skb are seen by multiple skbs but it only got skb_get
called once.
The same thing happens with a skb updated by pskb_may_pull() with a
skb_cloned skb. Li Shuang has reported quite a few crashes caused
by this when doing testing over macvlan devices:

This patch is to fix it by linearizing the head skb if it has frag_list
set in tipc_buf_append(). Note that we choose to do this before calling
skb_unshare(), as __skb_linearize() will avoid skb_copy(). Also, we can
not just drop the frag_list either as the early time.

commit 75ea44e356b5de8c817f821c9dd68ae329e82add upstream.
On some hosts, rlim.rlim_max can be returned as RLIM_INFINITY.
By casting it to int, it is interpreted as -1, which will cause get_maxfds
to return 0, causing "Invalid argument" errors in nftw() calls.
Fix this by casting the second argument of min() to rlim_t instead.

commit 75016891357a628d2b8acc09e2b9b2576c18d318 upstream.
This reverts commit 6bf24dc0cc0cc43b29ba344b66d78590e687e046.
Above fix is not correct and caused memory leak issue.

rt2880_wdt.c uses (well, attempts to use) rt_sysc_membase. However,
when this watchdog driver is built as a loadable module, there is a
build error since the rt_sysc_membase symbol is not exported.
Export it to quell the build error.
ERROR: modpost: "rt_sysc_membase" [drivers/watchdog/rt2880_wdt.ko] undefined!

commit 7c8c0291f84027558bd5fca5729cbcf288c510f4 upstream.
As part of the W=1 compliation series, these lines all created
warnings about unused variables that were assigned a value. Most
of them are from register reads, but some are just picking up
a return value from a function and never doing anything with it.
Fixed warnings:

The register reads should be OK, because the current
implementation of readl and friends will always execute even
without an lvalue.
When it makes sense, just remove the lvalue assignment and the
local. Other times, just remove the offending code, and
occasionally, just mark the variable as maybe unused since it
could be used in an ifdef or debug scenario.
Only compile tested with W=1.

commit 552546366a30d88bd1d6f5efe848b2ab50fd57e5 upstream.
A new clang diagnostic (-Wsizeof-array-div) warns about the calculation
to determine the number of u32's in an array of unsigned longs.
Suppress warning by adding parentheses.
While looking at the above issue, noticed that the 'address' parameter
to hugetlb_fault_mutex_hash is no longer used. So, remove it from the
definition and all callers.
No functional change.

Return the exactly delay time given by root hub descriptor,
this helps to reduce resume time etc.
Due to the root hub descriptor is usually provided by the host

commit 24990423267ec283b9d86f07f362b753eb9b0ed5 upstream.
Interrupt handler processes multiple message write requests one after
another, till the driver message queue is drained. However if driver
encounters a read message without preceding START, it stops the I2C
transfer as it is an invalid condition for the controller. At least the
comment describes a requirement "the controller forces us to send a new
START when we change direction". This stop results in clearing the
message queue (i2c->msg = NULL).
The code however immediately jumped back to label "retry_write" which
dereferenced the "i2c->msg" making it a possible NULL pointer
dereference.
The Coverity analysis:
1. Condition !is_msgend(i2c), taking false branch.
if (!is_msgend(i2c)) {
2. Condition !is_lastmsg(i2c), taking true branch.
} else if (!is_lastmsg(i2c)) {
3. Condition i2c->msg->flags & 1, taking true branch.
if (i2c->msg->flags & I2C_M_RD) {
4. write_zero_model: Passing i2c to s3c24xx_i2c_stop, which sets i2c->msg to NULL.
s3c24xx_i2c_stop(i2c, -EINVAL);
5. Jumping to label retry_write.
goto retry_write;
6. var_deref_model: Passing i2c to is_msgend, which dereferences null i2c->msg.
if (!is_msgend(i2c)) {"
All previous calls to s3c24xx_i2c_stop() in this interrupt service
routine are followed by jumping to end of function (acknowledging
the interrupt and returning). This seems a reasonable choice also here
since message buffer was entirely emptied.

hp_accel can take almost two seconds to resume on some HP laptops.
The bottleneck is on evaluating _INI, which is only needed to run once.
Resolve the issue by only invoking _INI when it's necessary. Namely, on

commit e4d8716c3dcec47f1557024add24e1f3c09eb24b upstream.
Now that the i2c-i801 driver supports interrupts, setting the KILL bit
in a attempt to recover from a timed out transaction triggers an
interrupt. Unfortunately, the interrupt handler (i801_isr) is not
prepared for this situation and will try to process the interrupt as
if it was signaling the end of a successful transaction. In the case
of a block transaction, this can result in an out-of-range memory
access.
This condition was reproduced several times by syzbot:
https://syzkaller.appspot.com/bug?extid=ed71512d469895b5b34e
https://syzkaller.appspot.com/bug?extid=8c8dedc0ba9e03f6c79e

https://syzkaller.appspot.com/bug?extid=b4d3fd1dfd53e90afd79
So disable interrupts while trying to reset the bus. Interrupts will
be enabled again for the following transaction.

Since commit bdcc2cd14e4e ("NFSv4.2: handle NFS-specific llseek errors"),
nfs42_proc_llseek would return -EOPNOTSUPP rather than -ENOTSUPP when
SEEK_DATA on NFSv4.0/v4.1.
This will lead xfstests generic/285 not run on NFSv4.0/v4.1 when set the
CONFIG_NFS_V4_2, rather than run failed.

Hi,
Apparently %pe is only supported up to (including) 5.5. It is not part
of 5.4.123.
So this patch should not be backported here or should be backported
differently, ie:
leave dev_err as-is
move "ret = PTR_ERR(tx_pipe->dma_queue);" 1 line above
(or %pe should be backported first)
PS: adding Dan Carpenter because we had a small discussion about some
potential backport issue when, using %pe
