commit 4a267bc5ea8f159b614d0549030216d0434eccca upstream.
Use power state to decide whether we can enter or leave IPS accurately,
and then prevent to power on/off twice.
The commit 6bf3a083407b ("wifi: rtw88: add flag check before enter or leave IPS")
would like to prevent this as well, but it still can't entirely handle all
cases. The exception is that WiFi gets connected and does suspend/resume,
it will power on twice and cause it failed to power on after resuming,
like:
rtw_8723de 0000:03:00.0: failed to poll offset=0x6 mask=0x2 value=0x2
rtw_8723de 0000:03:00.0: mac power on failed
rtw_8723de 0000:03:00.0: failed to power on mac
rtw_8723de 0000:03:00.0: leave idle state failed
rtw_8723de 0000:03:00.0: failed to leave ips state
rtw_8723de 0000:03:00.0: failed to leave idle state
rtw_8723de 0000:03:00.0: failed to send h2c command
To fix this, introduce new flag RTW_FLAG_POWERON to reflect power state,
and call rtw_mac_pre_system_cfg() to configure registers properly between
power-off/-on.

commit 7533afa1d27ba1234146d31d2402c195cf195962 upstream.
Device mapper sends an uevent when the device is suspended, using the
function set_capacity_and_notify. However, this causes a race condition
with udev.
Udev skips scanning dm devices that are suspended. If we send an uevent
while we are suspended, udev will be racing with device mapper resume
code. If the device mapper resume code wins the race, udev will process
the uevent after the device is resumed and it will properly scan the
device.
However, if udev wins the race, it will receive the uevent, find out that
the dm device is suspended and skip scanning the device. This causes bugs
such as systemd unmounting the device - see
https://bugzilla.redhat.com/show_bug.cgi?id=2158628
This commit fixes this race.
We replace the function set_capacity_and_notify with set_capacity, so that
the uevent is not sent at this point. In do_resume, we detect if the
capacity has changed and we pass a boolean variable need_resize_uevent to
dm_kobject_uevent. dm_kobject_uevent adds "RESIZE=1" to the uevent if
need_resize_uevent is set.

commit f0f0cfdc3a024e21161714f2e05f0df3b84d42ad upstream.
spi_nor_set_erase_type() was used either to set or to mask out an erase
type. When we used it to mask out an erase type a shift-out-of-bounds
was hit:
UBSAN: shift-out-of-bounds in drivers/mtd/spi-nor/core.c:2237:24
shift exponent 4294967295 is too large for 32-bit type 'int'
The setting of the size_{shift, mask} and of the opcode are unnecessary
when the erase size is zero, as throughout the code just the erase size
is considered to determine whether an erase type is supported or not.
Setting the opcode to 0xFF was wrong too as nobody guarantees that 0xFF
is an unused opcode. Thus when masking out an erase type, just set the
erase size to zero. This will fix the shift-out-of-bounds.

commit e6b9bd7290d334451ce054e98e752abc055e0034 upstream.
Following process will make data lost and could lead to a filesystem
corrupted problem:
1. jh(bh) is inserted into T1->t_checkpoint_list, bh is dirty, and
jh->b_transaction = NULL
2. T1 is added into journal->j_checkpoint_transactions.
3. Get bh prepare to write while doing checkpoing:
PA PB
do_get_write_access jbd2_log_do_checkpoint
spin_lock(&jh->b_state_lock)
if (buffer_dirty(bh))
clear_buffer_dirty(bh) // clear buffer dirty
set_buffer_jbddirty(bh)
transaction =
journal->j_checkpoint_transactions
jh = transaction->t_checkpoint_list
if (!buffer_dirty(bh))
__jbd2_journal_remove_checkpoint(jh)
// bh won't be flushed
jbd2_cleanup_journal_tail
__jbd2_journal_file_buffer(jh, transaction, BJ_Reserved)
4. Aborting journal/Power-cut before writing latest bh on journal area.
In this way we get a corrupted filesystem with bh's data lost.
Fix it by moving the clearing of buffer_dirty bit just before the call
to __jbd2_journal_file_buffer(), both bit clearing and jh->b_transaction
assignment are under journal->j_list_lock locked, so that
jbd2_log_do_checkpoint() will wait until jh's new transaction fininshed
even bh is currently not dirty. And journal_shrink_one_cp_list() won't
remove jh from checkpoint list if the buffer head is reused in
do_get_write_access().

It seems that the mutex is required only for aureon_cs8415_get(),
so snd_ice1712_restore_gpio_status(ice) can be placed
just after that. Compile tested only.

commit f6044cc3030e139f60c281386f28bda6e3049d66 upstream.
When preparing an AER-CTR request, the driver copies the key provided by
the user into a data structure that is accessible by the firmware.
If the target device is QAT GEN4, the key size is rounded up by 16 since
a rounded up size is expected by the device.
If the key size is rounded up before the copy, the size used for copying
the key might be bigger than the size of the region containing the key,
causing an out-of-bounds read.
Fix by doing the copy first and then update the keylen.
This is to fix the following warning reported by KASAN:

commit 8932c32c3053accd50702b36e944ac2016cd103c upstream.
Hierarchical domains created using irq_domain_create_hierarchy() are
currently added to the domain list before having been fully initialised.
This specifically means that a racing allocation request might fail to
allocate irq data for the inner domains of a hierarchy in case the
parent domain pointer has not yet been set up.
Note that this is not really any issue for irqchip drivers that are
registered early (e.g. via IRQCHIP_DECLARE() or IRQCHIP_ACPI_DECLARE())
but could potentially cause trouble with drivers that are registered
later (e.g. modular drivers using IRQCHIP_PLATFORM_DRIVER_BEGIN(),
gpiochip drivers, etc.).

commit 4971c268b85e1c7a734a61622fc0813c86e2362e upstream.
Commit 98de59bfe4b2f ("take calculation of final prot in
security_mmap_file() into a helper") moved the code to update prot, to be
the actual protections applied to the kernel, to a new helper called
mmap_prot().
However, while without the helper ima_file_mmap() was getting the updated
prot, with the helper ima_file_mmap() gets the original prot, which
contains the protections requested by the application.
A possible consequence of this change is that, if an application calls
mmap() with only PROT_READ, and the kernel applies PROT_EXEC in addition,
that application would have access to executable memory without having this
event recorded in the IMA measurement list. This situation would occur for
example if the application, before mmap(), calls the personality() system
call with READ_IMPLIES_EXEC as the first argument.
Align ima_file_mmap() parameters with those of the mmap_file LSM hook, so
that IMA can receive both the requested prot and the final prot. Since the
requested protections are stored in a new variable, and the final
protections are stored in the existing variable, this effectively restores
the original behavior of the MMAP_CHECK hook.
