[ Upstream commit 961c39121759ad09a89598ec4ccdd34ae0468a19 ]
When using per-process mode and event inheritance is set to true,
forked processes will create a new perf events via inherit_event() ->
perf_event_alloc(). But these events will not have ring buffers
assigned to them. Any call to wakeup will be dropped if it's called on
an event with no ring buffer assigned because that's the object that
holds the wakeup list.
If the child event is disabled due to a call to
perf_aux_output_begin() or perf_aux_output_end(), the wakeup is
dropped leaving userspace hanging forever on the poll.
Normally the event is explicitly re-enabled by userspace after it
wakes up to read the aux data, but in this case it does not get woken
up so the event remains disabled.
This can be reproduced when using Arm SPE and 'stress' which forks once
before running the workload. By looking at the list of aux buffers read,
it's apparent that they stop after the fork:
perf record -e arm_spe// -vvv -- stress -c 1
With this patch applied they continue to be printed. This behaviour
doesn't happen when using systemwide or per-cpu mode.

[ Upstream commit 62afb379a0fee7e9c2f9f68e1abeb85ceddf51b9 ]
According to the comment in check_fw_ready() we should not check the
IOP1_READY field in register SCRATCH_PAD_1 for 8008 or 8009 controllers.
However we check this very field in process_oq() for processing the highest
index interrupt vector. The highest interrupt vector is checked as the FW
is programmed to signal fatal errors through this irq.
Change that function to not check IOP1_READY for those mentioned
controllers, but do check ILA_READY in both cases.
The reason I assume that this was not hit earlier was because we always
allocated 64 MSI(X), and just did not pass the vector index check in
process_oq(), i.e. the handler never ran for vector index 63.

It is mandatory for a software to issue a reset upon modifying RGMII
Receive Timing Control and RGMII Transmit Timing Control bit fields of MAC
Specific Control register 2 (page 2, register 21) otherwise the changes
won't be perceived by the PHY (the same is applicable for a lot of other

discovered that the denoted soft-reset is missing in the

modified but the MDIx polarity isn't changed or the auto-negotiation is
left enabled, thus causing the traffic loss on our platform with Marvell

delays have been actually set in the m88e1121_config_aneg_rgmii_delays()

Commit c2426d2ad5027 ("ima: added support for new kernel cmdline parameter

variable to avoid multiple template selection.
Unfortunately, ima_template could be also set by the setup function of the
ima_hash= parameter, when it calls ima_template_desc_current(). This causes
attempts to choose a new template with ima_template= or with
ima_template_fmt=, after ima_hash=, to be ignored.
Achieve the goal of the commit mentioned with the new static variable
template_setup_done, so that template selection requests after ima_hash=
are not ignored.
Finally, call ima_init_template_list(), if not already done, to initialize
the list of templates before lookup_template_desc() is called.

commit 9aa422ad326634b76309e8ff342c246800621216 upstream.
The function tipc_mon_rcv() allows a node to receive and process
domain_record structs from peer nodes to track their views of the
network topology.
This patch verifies that the number of members in a received domain
record does not exceed the limit defined by MAX_MON_DOMAIN, something
that may otherwise lead to a stack overflow.
tipc_mon_rcv() is called from the function tipc_link_proto_rcv(), where
we are reading a 32 bit message data length field into a uint16. To
avert any risk of bit overflow, we add an extra sanity check for this in
that function. We cannot see that happen with the current code, but
future designers being unaware of this risk, may introduce it by
allowing delivery of very large (> 64k) sk buffers from the bearer
layer. This potential problem was identified by Eric Dumazet.
This fixes CVE-2022-0435

commit c6ce9c5831cae515d375a01b97ae1778689acf19 upstream.
The soft dependency on cryptomgr is only needed in algapi because
if algapi isn't present then no algorithms can be loaded. This
also fixes the case where api is built-in but algapi is built as
a module as the soft dependency would otherwise get lost.

commit 2bdfd2825c9662463371e6691b1a794e97fa36b4 upstream.
It was found that a "suspicious RCU usage" lockdep warning was issued
with the rcu_read_lock() call in update_sibling_cpumasks(). It is
because the update_cpumasks_hier() function may sleep. So we have
to release the RCU lock, call update_cpumasks_hier() and reacquire
it afterward.
Also add a percpu_rwsem_assert_held() in update_sibling_cpumasks()
instead of stating that in the comment.

commit 897026aaa73eb2517dfea8d147f20ddb0b813044 upstream.
While running "./check -I 200 generic/475" it sometimes gives below
kernel BUG(). Ideally we should not call ext4_write_inline_data() if
ext4_create_inline_data() has failed.
<log snip>

This patch handles the error and prints out a emergency msg saying potential
data loss for the given inode (since we couldn't restore the original
inline_data due to some previous error).

should be excluded then will switch to next group, this may
probably cause 'group' run out of range.

be excluded. Also change the search range to EXT4_CLUSTERS_PER_GROUP
