commit 246bbf2f977ea36aaf41f5d24370fef433250728 upstream.
If the port isn't a CPU port nor a user port, 'cpu_dp'

commit 8d48562a2729742f767b0fdd994d6b2a56a49c63 upstream.
The recent change to get_phb_number() causes a DEBUG_ATOMIC_SLEEP
warning on some systems:

This is because pcibios_alloc_controller() holds hose_spinlock but
of_alias_get_id() takes of_mutex which can sleep.
The hose_spinlock protects the phb_bitmap, and also the hose_list, but
it doesn't need to be held while get_phb_number() calls the OF routines,
because those are only looking up information in the device tree.
So fix it by having get_phb_number() take the hose_spinlock itself, only
where required, and then dropping the lock before returning.
pcibios_alloc_controller() then needs to take the lock again before the
list_add() but that's safe, the order of the list is not important.

commit fd0c153daad135d0ec1a53c5dbe6936a724d6ae1 upstream.
If we use the ancient SysV syscall ABI, we'd better have tell the
kernel how to claim that a negative return value is a success.
Use ->orig_r2 for that - it's inaccessible via ptrace, so it's
a fair game for changes and it's normally[*] non-negative on return
from syscall. Set to -1; syscall is not going to be restart-worthy
by definition, so we won't interfere with that use either.
[*] the only exception is rt_sigreturn(), where we skip the entire
messing with r1/r2 anyway.

commit 3f4093e2bf4673f218c0bf17d8362337c400e77b upstream.
There are use-after-free bugs caused by tst_timer. The root cause
is that there are no functions to stop tst_timer in idt77252_exit().
One of the possible race conditions is shown below:
(thread 1) | (thread 2)
| idt77252_init_one
| init_card
| fill_tst
| mod_timer(&card->tst_timer, ...)
idt77252_exit | (wait a time)
| tst_timer
|
| ...
kfree(card) // FREE |
| card->soft_tst[e] // USE
The idt77252_dev is deallocated in idt77252_exit() and used in
timer handler.
This patch adds del_timer_sync() in idt77252_exit() in order that
the timer handler could be stopped before the idt77252_dev is
deallocated.

This code tries to store -EFAULT in an unsigned int. The
xenbus_file_read() function returns type ssize_t so the negative value
is returned as a positive value to the user.
This change forces another change to the min() macro. Originally, the
min() macro used "unsigned" type which checkpatch complains about. Also
unsigned type would break if "len" were not capped at MAX_RW_COUNT. Use
size_t for the min(). (No effect on runtime for the min_t() change).

commit 4ae97cae07e15d41e5c0ebabba64c6eefdeb0bbe upstream.
The port flag isn't set to `NFP_PORT_CHANGED` when using
`ethtool -m DEVNAME` before, so the port state (e.g. interface)
cannot be updated. Therefore, it caused that `ethtool -m DEVNAME`
sometimes cannot read the correct information.
E.g. `ethtool -m DEVNAME` cannot work when load driver before plug
in optical module, as the port interface is still NONE without port
update.
Now update the port state before sending info to NIC to ensure that
port interface is correct (latest state).

The call to:
ret = simple_write_to_buffer(buf, size, offp, ubuf, size);
will return success if it is able to write even one byte to "buf".
The value of "*offp" controls which byte. This could result in
reading uninitialized data when we do the sscanf() on the next line.
This code is not really desigined to handle partial writes where
*offp is non-zero and the "buf" is preserved and re-used between writes.
Just ban partial writes and replace the simple_write_to_buffer() with
copy_from_user().

This problem is caused by the sort_slabs(). So let's use alphabetic order
when two values are equal in the sort_slabs().
By the way, the content of the `slabinfo -h` is not aligned because the
`-P|--partial Sort by number of partial slabs`
uses tabs instead of spaces. So let's use spaces instead of tabs to fix
it.

commit a3e7b29e30854ed67be0d17687e744ad0c769c4b upstream.
Imagine two non-blocking vsock_connect() requests on the same socket.
The first request schedules @connect_work, and after it times out,
vsock_connect_timeout() sets *sock* state back to TCP_CLOSE, but keeps
*socket* state as SS_CONNECTING.
Later, the second request returns -EALREADY, meaning the socket "already
has a pending connection in progress", even though the first request has
already timed out.
As suggested by Stefano, fix it by setting *socket* state back to
SS_UNCONNECTED, so that the second request will return -ETIMEDOUT.

commit 7e97cfed9929eaabc41829c395eb0d1350fccb9d upstream.
An O_NONBLOCK vsock_connect() request may try to reschedule
@connect_work. Imagine the following sequence of vsock_connect()
requests:
1. The 1st, non-blocking request schedules @connect_work, which will
expire after 200 jiffies. Socket state is now SS_CONNECTING;
2. Later, the 2nd, blocking request gets interrupted by a signal after
a few jiffies while waiting for the connection to be established.
Socket state is back to SS_UNCONNECTED, but @connect_work is still
pending, and will expire after 100 jiffies.
3. Now, the 3rd, non-blocking request tries to schedule @connect_work
again. Since @connect_work is already scheduled,
schedule_delayed_work() silently returns. sock_hold() is called
twice, but sock_put() will only be called once in
vsock_connect_timeout(), causing a memory leak reported by syzbot:

commit ca2bb69514a8bc7f83914122f0d596371352416c upstream.
According to Guillaume Nault RT_TOS should never be used for IPv6.
Quote:
RT_TOS() is an old macro used to interprete IPv4 TOS as described in
the obsolete RFC 1349. It's conceptually wrong to use it even in IPv4
code, although, given the current state of the code, most of the
existing calls have no consequence.
But using RT_TOS() in IPv6 code is always a bug: IPv6 never had a "TOS"
field to be interpreted the RFC 1349 way. There's no historical
compatibility to worry about.

commit 6b4db2e528f650c7fb712961aac36455468d5902 upstream.
After a failed devlink reload, devlink parameters are still registered,
which means user space can set and get their values. In the case of the
mlxsw "acl_region_rehash_interval" parameter, these operations will
trigger a use-after-free [1].
Fix this by rejecting set and get operations while in the failed state.
Return the "-EOPNOTSUPP" error code which does not abort the parameters
dump, but instead causes it to skip over the problematic parameter.
Another possible fix is to perform these checks in the mlxsw parameter
callbacks, but other drivers might be affected by the same problem and I
am not aware of scenarios where these stricter checks will cause a
regression.

commit d80d60b0db6ff3dd2e29247cc2a5166d7e9ae37e upstream.
The mcp251x driver uses both receiving mailboxes of the CAN controller
chips. For retrieving the CAN frames from the controller via SPI, it checks
once per interrupt which mailboxes have been filled and will retrieve the
messages accordingly.
This introduces a race condition, as another CAN frame can enter mailbox 1
while mailbox 0 is emptied. If now another CAN frame enters mailbox 0 until
the interrupt handler is called next, mailbox 0 is emptied before
mailbox 1, leading to out-of-order CAN frames in the network device.
This is fixed by checking the interrupt flags once again after freeing
mailbox 0, to correctly also empty mailbox 1 before leaving the handler.
For reproducing the bug I created the following setup:
- Two CAN devices, one Raspberry Pi with MCP2515, the other can be any.
- Setup CAN to 1 MHz
- Spam bursts of 5 CAN-messages with increasing CAN-ids
- Continue sending the bursts while sleeping a second between the bursts
- Check on the RPi whether the received messages have increasing CAN-ids
- Without this patch, every burst of messages will contain a flipped pair

idmap_pipe_downcall() from the first process has not yet finished
calling nfs_idmap_complete_pipe_upcall_locked(), then we may end up
triggering the WARN_ON_ONCE() in nfs_idmap_prepare_pipe_upcall().

commit 511f7b5b835726e844a5fc7444c18e4b8672edfd upstream.
AppArmor is prefixing secids that are converted to secctx with the =
to indicate the secctx should only be parsed from an absolute root
POV. This allows catching errors where secctx are reparsed back into
internal labels.
Unfortunately because audit is using secid to secctx conversion this
means that subject and object labels can result in a very unfortunate
== that can break audit parsing.
eg. the subj==unconfined term in the below audit message
type=USER_LOGIN msg=audit(1639443365.233:160): pid=1633 uid=0 auid=1000
ses=3 subj==unconfined msg='op=login id=1000 exe="/usr/sbin/sshd"
hostname=192.168.122.1 addr=192.168.122.1 terminal=/dev/pts/1 res=success'
Fix this by switch the prepending of = to a _. This still works as a
special character to flag this case without breaking audit. Also move
this check behind debug as it should not be needed during normal
operqation.

clang emits a -Wunaligned-access warning on struct __packed
ems_cpc_msg.
The reason is that the anonymous union msg (not declared as packed) is
being packed right after some non naturally aligned variables (3*8
bits + 2*32) inside a packed struct:
| struct __packed ems_cpc_msg {
| u8 type; /* type of message */
| u8 length; /* length of data within union 'msg' */
| u8 msgid; /* confirmation handle */
| __le32 ts_sec; /* timestamp in seconds */
| __le32 ts_nsec; /* timestamp in nano seconds */
| /* ^ not naturally aligned */
|
| union {

| u8 generic[64];

| struct cpc_overrun overrun;
| struct cpc_can_error error;
| struct cpc_can_err_counter err_counter;
| u8 can_state;
| } msg;
| };
Starting from LLVM 14, having an unpacked struct nested in a packed
struct triggers a warning. c.f. [1].
Fix the warning by marking the anonymous union as packed.

commit b2380577d4fe1c0ef3fa50417f1e441c016e4cbe upstream.
Make filtering consistent with histograms. As "cpu" can be a field of an
event, allow for "common_cpu" to keep it from being confused with the
"cpu" field of the event.

commit 7a6b75b79902e47f46328b57733f2604774fa2d9 upstream.
During log replay, when processing inode references, if we get an error
when looking up for an extended reference at __add_inode_ref(), we ignore
it and proceed, returning success (0) if no other error happens after the
lookup. This is obviously wrong because in case an extended reference
exists and it encodes some name not in the log, we need to unlink it,
otherwise the filesystem state will not match the state it had after the
last fsync.
So just make __add_inode_ref() return an error it gets from the extended
reference lookup.

commit 98d7c5e5792b8ce3e1352196dac7f404bb1b46ec upstream.
The commit in Fixes: has moved some code around without updating gotos to
the error handling path.
Update it now and release some resources if pxamci_of_init() fails.
Fixes: fa3a5115469c ("mmc: pxamci: call mmc_of_parse()")
