[ Upstream commit 6b8526d3abc02c08a2f888e8c20b7ac9e5776dfe ]
In error cases a NULL can be passed to memcpy. The length will always
be zero, so it doesn't really matter, but go ahead and check for NULL,
anyway, to be more precise and avoid static analysis errors.Reported-by: kbuild test robot

commit dc10e4181c05a2315ddc375e963b7c763b5ee0df upstream.
chip->allocated_banks, an array of tpm_bank_info structures, contains the
list of TPM algorithm IDs of allocated PCR banks. It also contains the
corresponding ID of the crypto subsystem, so that users of the TPM driver
can calculate a digest for a PCR extend operation.However, if there is no mapping between TPM algorithm ID and crypto ID, the
crypto_id field of tpm_bank_info remains set to zero (the array is
allocated and initialized with kcalloc() in tpm2_get_pcr_allocation()).
Zero should not be used as value for unknown mappings, as it is a valid
crypto ID (HASH_ALGO_MD4).Thus, initialize crypto_id to HASH_ALGO__LAST.

Currently, there is only spin lock added in imx_sema4_mutex_lock(),but
sema4 driver assume any mutex should be handled one by one and complain
when mutex locked once again before unlocked. Hence, if another lock happens
indeed after the last imx_sema4_mutex_lock(),the complains "imx_sema4_
mutex_lock 135 already locked" would come out over again and again as below.
So delay lock released into imx_sema4_mutex_unlock() to elimate such race
contition.Thread1: Thread2:

[ Upstream commit 98c49f1746ac44ccc164e914b9a44183fad09f51 ]
Currently, there is an out-of-bounds read on array hpetp->hp_dev
in the following for loop:870 for (i = 0; i < hdp->hd_nirqs; i++)
871 hpetp->hp_dev[i].hd_hdwirq = hdp->hd_irq[i];This is due to the recent change from one-element array to
flexible-array member in struct hpets:104 struct hpets {
...
113 struct hpet_dev hp_dev[];
114 };This change affected the total size of the dynamic memory
allocation, decreasing it by one time the size of struct hpet_dev.Fix this by adjusting the allocation size when calling
struct_size().Fixes: 987f028b8637c ("char: hpet: Use flexible-array member")

Sergey didn't like the locking order,
uart_port->lock -> tty_port->lock
uart_write (uart_port->lock)
__uart_start
pl011_start_tx
pl011_tx_chars
uart_write_wakeup
tty_port_tty_wakeup
tty_port_default
tty_port_tty_get (tty_port->lock)but those code is so old, and I have no clue how to de-couple it after
checking other locks in the splat. There is an onging effort to make all
printk() as deferred, so until that happens, workaround it for now as a
short-term fix.LTP: starting iogen01 (export LTPROOT; rwtest -N iogen01 -i 120s -s

Commit 0ed266d7ae5e ("clk: ti: omap3: cleanup unnecessary clock aliases")
removed old omap3 clock framework aliases but caused omap3-rom-rng to
stop working with clock not found error.Based on discussions on the mailing list it was requested by Tero Kristo
that it would be best to fix this issue by probing omap3-rom-rng using
device tree to provide a proper clk property. The other option would be
to add back the missing clock alias, but that does not help moving things
forward with removing old legacy platform_data.Let's also add a proper device tree binding and keep it together with
the fix.Cc: devicetree@vger.kernel.org

There has been a bunch of reports (one from kernel bugzilla linked)
reporting that when this commit is applied it causes on some machines
boot freezes.Unfortunately hardware where this commit causes a failure is not widely
available (only one I'm aware is Lenovo T490), which means we cannot
predict yet how long it will take to properly fix tpm_tis interrupt

commit d23d12484307b40eea549b8a858f5fffad913897 upstream.
When an application sends TPM commands in NONBLOCKING mode
the driver holds chip->tpm_mutex returning from write(),
which triggers: "WARNING: lock held when returning to user space".
To fix this issue the driver needs to release the mutex before
returning and acquire it again in tpm_dev_async_work() before
sending the command.Cc: stable@vger.kernel.org

[ Upstream commit cbb79863fc3175ed5ac506465948b02a893a8235 ]
If something has the IPMI driver open, don't allow the device
module to be unloaded. Before it would unload and the user would
get errors on use.This change is made on user request, and it makes it consistent
with the I2C driver, which has the same behavior.It does change things a little bit with respect to kernel users.
If the ACPI or IPMI watchdog (or any other kernel user) has
created a user, then the device module cannot be unloaded. Before
it could be unloaded,This does not affect hot-plug. If the device goes away (it's on
something removable that is removed or is hot-removed via sysfs)
then it still behaves as it did before.Reported-by: tony camuso

Merge active entropy generation updates.
This is admittedly partly "for discussion". We need to have a way
forward for the boot time deadlocks where user space ends up waiting for
more entropy, but no entropy is forthcoming because the system is
entirely idle just waiting for something to happen.While this was triggered by what is arguably a user space bug with
GDM/gnome-session asking for secure randomness during early boot, when
they didn't even need any such truly secure thing, the issue ends up
being that our "getrandom()" interface is prone to that kind of
confusion, because people don't think very hard about whether they want
to block for sufficient amounts of entropy.The approach here-in is to decide to not just passively wait for entropy
to happen, but to start actively collecting it if it is missing. This
is not necessarily always possible, but if the architecture has a CPU
cycle counter, there is a fair amount of noise in the exact timings of
reasonably complex loads.We may end up tweaking the load and the entropy estimates, but this
should be at least a reasonable starting point.As part of this, we also revert the revert of the ext4 IO pattern
improvement that ended up triggering the reported lack of external
entropy.* getrandom() active entropy waiting:
Revert "Revert "ext4: make __ext4_get_inode_loc plug""
random: try to actively add entropy rather than passively wait for it -
For 5.3 we had to revert a nice ext4 IO pattern improvement, because it
caused a bootup regression due to lack of entropy at bootup together
with arguably broken user space that was asking for secure random
numbers when it really didn't need to.See commit 72dbcf721566 (Revert "ext4: make __ext4_get_inode_loc plug").
This aims to solve the issue by actively generating entropy noise using
the CPU cycle counter when waiting for the random number generator to
initialize. This only works when you have a high-frequency time stamp
counter available, but that's the case on all modern x86 CPU's, and on
most other modern CPU's too.What we do is to generate jitter entropy from the CPU cycle counter
under a somewhat complex load: calling the scheduler while also
guaranteeing a certain amount of timing noise by also triggering a
timer.I'm sure we can tweak this, and that people will want to look at other
alternatives, but there's been a number of papers written on jitter
entropy, and this should really be fairly conservative by crediting one
bit of entropy for every timer-induced jump in the cycle counter. Not
because the timer itself would be all that unpredictable, but because
the interaction between the timer and the loop is going to be.Even if (and perhaps particularly if) the timer actually happens on
another CPU, the cacheline interaction between the loop that reads the
cycle counter and the timer itself firing is going to add perturbations
to the cycle counter values that get mixed into the entropy pool.As Thomas pointed out, with a modern out-of-order CPU, even quite simple
loops show a fair amount of hard-to-predict timing variability even in
the absense of external interrupts. But this tries to take that further
by actually having a fairly complex interaction.This is not going to solve the entropy issue for architectures that have
no CPU cycle counter, but it's not clear how (and if) that is solvable,
and the hardware in question is largely starting to be irrelevant. And
by doing this we can at least avoid some of the even more contentious
approaches (like making the entropy waiting time out in order to avoid
the possibly unbounded waiting).Cc: Ahmed Darwish

Pull kernel lockdown mode from James Morris:
"This is the latest iteration of the kernel lockdown patchset, from
Matthew Garrett, David Howells and others.From the original description:
This patchset introduces an optional kernel lockdown feature,
intended to strengthen the boundary between UID 0 and the kernel.
When enabled, various pieces of kernel functionality are restricted.
Applications that rely on low-level access to either hardware or the
kernel may cease working as a result - therefore this should not be
enabled without appropriate evaluation beforehand.The majority of mainstream distributions have been carrying variants
of this patchset for many years now, so there's value in providing a
doesn't meet every distribution requirement, but gets us much closer
to not requiring external patches.There are two major changes since this was last proposed for mainline:
- Separating lockdown from EFI secure boot. Background discussion is
covered here: https://lwn.net/Articles/751061/- Implementation as an LSM, with a default stackable lockdown LSM
module. This allows the lockdown feature to be policy-driven,
rather than encoding an implicit policy within the mechanism.The new locked_down LSM hook is provided to allow LSMs to make a
policy decision around whether kernel functionality that would allow
tampering with or examining the runtime state of the kernel should be
permitted.The included lockdown LSM provides an implementation with a simple
policy intended for general purpose use. This policy provides a coarse
level of granularity, controllable via the kernel command line:lockdown={integrity|confidentiality}
Enable the kernel lockdown feature. If set to integrity, kernel features
that allow userland to modify the running kernel are disabled. If set to
confidentiality, kernel features that allow userland to extract
confidential information from the kernel are also disabled.This may also be controlled via /sys/kernel/security/lockdown and
overriden by kernel configuration.New or existing LSMs may implement finer-grained controls of the
lockdown features. Refer to the lockdown_reason documentation in
include/linux/security.h for details.The lockdown feature has had signficant design feedback and review
across many subsystems. This code has been in linux-next for some
weeks, with a few fixes applied along the way.Stephen Rothwell noted that commit 9d1f8be5cf42 ("bpf: Restrict bpf
when kernel lockdown is in confidentiality mode") is missing a

tpm_send() does not give anymore the result back to the caller. This
would require another memcpy(), which kind of tells that the whole
approach is somewhat broken. Instead, as Mimi suggested, this commit
just wraps the data to the tpm_buf, and thus the result will not go to
the garbage.Obviously this assumes from the caller that it passes large enough
buffer, which makes the whole API somewhat broken because it could be
different size than @buflen but since trusted keys is the only module
using this API right now I think that this fix is sufficient for the
moment.In the near future the plan is to replace the parameters with a tpm_buf
created by the caller.Reported-by: Mimi Zohar

add_early_randomness() is called by hwrng_register() when the
hardware is added. If this hardware and its module are present
at boot, and if there is no data available the boot hangs until
data are available and can't be interrupted.For instance, in the case of virtio-rng, in some cases the host can be
not able to provide enough entropy for all the guests.We can have two easy ways to reproduce the problem but they rely on
misconfiguration of the hypervisor or the egd daemon:- if virtio-rng device is configured to connect to the egd daemon of the
host but when the virtio-rng driver asks for data the daemon is not
connected,- if virtio-rng device is configured to connect to the egd daemon of the
host but the egd daemon doesn't provide data.The guest kernel will hang at boot until the virtio-rng driver provides
enough data.To avoid that, call rng_get_data() in non-blocking mode (wait=0)
from add_early_randomness().Signed-off-by: Laurent Vivier
