- kprobes: Fix possible use-after-free issue on kprobe registration. Since
check_kprobe_address_safe() uses `is_module_text_address()` and
`__module_text_address()` separately, if the probe address is on an
unloading module, the first `is_module_text_address()` return true but
the second `__module_text_address()` returns NULL (module is unloaded
between them). Thus it expects the probe is on the kernel text, and
skips to get the module reference. In this case, when it arms a breakpoint
on the probe address, it may cause a use-after-free problem.
To fix this issue, we only use `__module_text_address()` once and tries
to get reference of the module, if it fails, reject the probe.

"Fix possible use-after-free issue on kprobe registration.
check_kprobe_address_safe() uses `is_module_text_address()` and
`__module_text_address()` separately.
As a result, if the probed address is in a module that is being
unloaded, the first `is_module_text_address()` might return true but
then the `__module_text_address()` call might return NULL if the

The result is that kprobe believes the probe is on the kernel text,

The cros_ec_uart_probe() function calls devm_serdev_device_open() before
it calls serdev_device_set_client_ops(). This can trigger a NULL pointer
dereference:
BUG: kernel NULL pointer dereference, address: 0000000000000000
...
Call Trace:
<TASK>
...
? ttyport_receive_buf
A simplified version of crashing code is as follows:
static inline size_t serdev_controller_receive_buf(struct serdev_controller *ctrl,
const u8 *data,
size_t count)
{
struct serdev_device *serdev = ctrl->serdev;
if (!serdev || !serdev->ops->receive_buf) // CRASH!
return 0;
return serdev->ops->receive_buf(serdev, data, count);
}
It assumes that if SERPORT_ACTIVE is set and serdev exists, serdev->ops
will also exist. This conflicts with the existing cros_ec_uart_probe()
logic, as it first calls devm_serdev_device_open() (which sets
SERPORT_ACTIVE), and only later sets serdev->ops via
serdev_device_set_client_ops().
Commit 01f95d42b8 ("platform/chrome: cros_ec_uart: fix race
condition") attempted to fix a similar race condition, but while doing
so, made the window of error for this race condition to happen much
wider.
Attempt to fix the race condition again, making sure we fully setup
before calling devm_serdev_device_open().

When unloading a module, its state is changing MODULE_STATE_LIVE ->
MODULE_STATE_GOING -> MODULE_STATE_UNFORMED. Each change will take
a time. `is_module_text_address()` and `__module_text_address()`
works with MODULE_STATE_LIVE and MODULE_STATE_GOING.
If we use `is_module_text_address()` and `__module_text_address()`
separately, there is a chance that the first one is succeeded but the
next one is failed because module->state becomes MODULE_STATE_UNFORMED
between those operations.
In `check_kprobe_address_safe()`, if the second `__module_text_address()`
is failed, that is ignored because it expected a kernel_text address.
But it may have failed simply because module->state has been changed
to MODULE_STATE_UNFORMED. In this case, arm_kprobe() will try to modify
non-exist module text address (use-after-free).
To fix this problem, we should not use separated `is_module_text_address()`
and `__module_text_address()`, but use only `__module_text_address()`
once and do `try_module_get(module)` which is only available with
MODULE_STATE_LIVE.

...
package_09_die_00/

The culprit is an incorrect sprintf format string "package_0%d_die_0%d" used
with each instance of reading uncore frequency files. uncore-frequency-common.c
creates the sysfs directory with the format "package_%02d_die_%02d". Once the

BHI mitigation mode spectre_bhi=auto does not deploy the software
mitigation by default. In a cloud environment, it is a likely scenario
where userspace is trusted but the guests are not trusted. Deploying
system wide mitigation in such cases is not desirable.
Update the auto mode to unconditionally mitigate against malicious
guests. Deploy the software sequence at VMexit in auto mode also, when
hardware mitigation is not available. Unlike the force =on mode,
software sequence is not deployed at syscalls in auto mode.

Branch history clearing software sequences and hardware control
BHI_DIS_S were defined to mitigate Branch History Injection (BHI).
Add cmdline spectre_bhi={on|off|auto} to control BHI mitigation:
auto - Deploy the hardware mitigation BHI_DIS_S, if available.
on - Deploy the hardware mitigation BHI_DIS_S, if available,
otherwise deploy the software sequence at syscall entry and
VMexit.
off - Turn off BHI mitigation.
The default is auto mode which does not deploy the software sequence
mitigation. This is because of the hardening done in the syscall
dispatch path, which is the likely target of BHI.

Branch History Injection (BHI) attacks may allow a malicious application to
influence indirect branch prediction in kernel by poisoning the branch
history. eIBRS isolates indirect branch targets in ring0. The BHB can
still influence the choice of indirect branch predictor entry, and although
branch predictor entries are isolated between modes when eIBRS is enabled,
the BHB itself is not isolated between modes.
Alder Lake and new processors supports a hardware control BHI_DIS_S to
mitigate BHI. For older processors Intel has released a software sequence
to clear the branch history on parts that don't support BHI_DIS_S. Add
support to execute the software sequence at syscall entry and VMexit to
overwrite the branch history.
For now, branch history is not cleared at interrupt entry, as malicious
applications are not believed to have sufficient control over the
registers, since previous register state is cleared at interrupt
entry. Researchers continue to poke at this area and it may become
necessary to clear at interrupt entry as well in the future.
This mitigation is only defined here. It is enabled later.

Make <asm/syscall.h> build a switch statement instead, and the compiler can
either decide to generate an indirect jump, or - more likely these days due
to mitigations - just a series of conditional branches.
Yes, the conditional branches also have branch prediction, but the branch
prediction is much more controlled, in that it just causes speculatively
running the wrong system call (harmless), rather than speculatively running
possibly wrong random less controlled code gadgets.
This doesn't mitigate other indirect calls, but the system call indirection
is the first and most easily triggered case.

ACER Vivobook Flip (TP401NAS) virtual intel switch is implemented as
follow:
Device (VGBI)
{
Name (_HID, EisaId ("INT33D6") ...
Name (VBDS, Zero)
Method (_STA, 0, Serialized) // _STA: Status ...
Method (VBDL, 0, Serialized)
{
PB1E |= 0x20
VBDS |= 0x40
}
Method (VGBS, 0, Serialized)
{
Return (VBDS) /* \_SB_.PCI0.SBRG.EC0_.VGBI.VBDS */
}
...
}
By default VBDS is set to 0. At boot it is set to clamshell (bit 6 set)
only after method VBDL is executed.
Since VBDL is now evaluated in the probe routine later, after the device
is registered, the retrieved value of VBDS was still 0 ("tablet mode")
when setting up the virtual switch.
Make sure to evaluate VGBS after VBDL, to ensure the
convertible boots in clamshell mode, the expected default.
