The regular expression that matches the version number of a utility
being queried is used as a constant expression in the current
implementation. Assigning the RE in question to a variable gives it a
meaningful name that clearly expresses the intended use of the expression
without having to think about the details of implementation.

IndexCard is indirectly controlled by user-space, hence leading to
a potential exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/char/applicom.c:418 ac_write() warn: potential spectre issue 'apbs' [r]
drivers/char/applicom.c:728 ac_ioctl() warn: potential spectre issue 'apbs' [r] (local cap)
Fix this by sanitizing IndexCard before using it to index apbs.
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

Commit '3d035f580699 ("drivers/char/hpet.c: allow user controlled mmap for
user processes")' introduced a new kernel command line parameter hpet_mmap,
that is required to expose the memory map of the HPET registers to
user-space. Unfortunately the kernel command line parameter 'hpet_mmap' is
broken and never takes effect due to missing '=' character in the __setup()
code of hpet_mmap_enable.
Before this patch:
dmesg output with the kernel command line parameter hpet_mmap=1
[ 0.204152] HPET mmap disabled
dmesg output with the kernel command line parameter hpet_mmap=0
[ 0.204192] HPET mmap disabled
After this patch:
dmesg output with the kernel command line parameter hpet_mmap=1
[ 0.203945] HPET mmap enabled
dmesg output with the kernel command line parameter hpet_mmap=0
[ 0.204652] HPET mmap disabled

Adopt nvram module to reduce code duplication. This means CONFIG_NVRAM
becomes available to PPC64 builds. Previously it was only available to
PPC32 builds because it depended on CONFIG_GENERIC_NVRAM.
The IOC_NVRAM_GET_OFFSET ioctl as implemented on PPC64 validates the
offset returned by pmac_get_partition(). Do the same in the nvram module.
Note that the old PPC32 generic_nvram module lacked this test.
So when CONFIG_PPC32 && CONFIG_PPC_PMAC, the IOC_NVRAM_GET_OFFSET ioctl
would have returned 0 (always). But when CONFIG_PPC64 && CONFIG_PPC_PMAC,
the IOC_NVRAM_GET_OFFSET ioctl would have returned -1 (which is -EPERM)
when the requested partition was not found.
With this patch, the result is now -EINVAL on both PPC32 and PPC64 when
the requested PowerMac NVRAM partition is not found. This is a userspace-
visible change, in the non-existent partition case, which would be in
an error path for an IOC_NVRAM_GET_OFFSET ioctl syscall.

This patch addresses inconsistencies in Mac framebuffer drivers and their
use of Kconfig symbols relating to NVRAM, so PPC64 can use CONFIG_NVRAM.
The defined(CONFIG_NVRAM) condition is replaced with the weaker
IS_REACHABLE(CONFIG_NVRAM) condition, like atari_scsi.
Macintosh framebuffer drivers use default settings for color mode and
video mode that are found in NVRAM. On PCI Macs, MacOS stores display
settings in the Name Registry (NR) partition in NVRAM*. On NuBus Macs,
there is no NR partition and MacOS stores display mode settings in PRAM**.
Early-model Macs are the ones most likely to benefit from these settings,
since they are more likely to have a fixed-frequency monitor connected to
the built-in framebuffer device. Moreover, a single NV_CMODE value and
a single NV_VMODE value provide for only one display.
The NV_CMODE and NV_VMODE constants are apparently offsets into the NR
partition for Old World machines. This also suggests that these defaults
are not useful on later models. The NR partition seems to be optional on
New World machines. CONFIG_NVRAM cannot be enabled on PPC64 at present.
It is safe to say that NVRAM support in PowerMac fbdev drivers is only
applicable to CONFIG_PPC32 so make this condition explicit. This means
matroxfb driver won't crash on PPC64 when CONFIG_NVRAM becomes available
there.
For imsttfb, add the missing CONFIG_NVRAM test to prevent a build failure,
since PPC64 does not implement nvram_read_byte(). Also add a missing
machine_is(powermac) check. Change the inconsistent dependency on
CONFIG_PPC and the matching #ifdef tests to CONFIG_PPC_PMAC.
For valkyriefb, to improve clarity and consistency with the other PowerMac
fbdev drivers, test for CONFIG_PPC_PMAC instead of !CONFIG_MAC. Remove a
bogus comment regarding PRAM.

Refactor the RTC "CMOS" NVRAM functions so that they can be used as
arch_nvram_ops methods. Checksumming logic is moved from the misc device
operations to the nvram read/write operations. This makes the misc device
implementation more generic.
This preserves the locking mechanism such that "read if checksum valid"
and "write and update checksum" remain atomic operations.
Some platforms implement byte-range read/write methods which are similar
to file_operations struct methods. Other platforms provide only
byte-at-a-time methods. The former are more efficient but may be
unavailable so fall back on the latter methods when necessary.

NVRAM, for which it provides appropriate checksum ioctls. Make these

functions while others have byte-range accessor functions. Some have

make use of the available NVRAM functionality in a portable way.

This patch effectively disables existing NVRAM functionality so as to

On powerpc, setting CONFIG_NVRAM=n builds a kernel with no NVRAM support.
Setting CONFIG_NVRAM=m enables the /dev/nvram misc device module without
enabling NVRAM support in drivers. Setting CONFIG_NVRAM=y enables the
misc device (built-in) and also enables NVRAM support in drivers.
m68k shares the valkyriefb driver with powerpc, and since that driver uses
NVRAM, it is affected by CONFIG_ATARI_SCSI, because of the use of
"select NVRAM". We can avoid the "select" here, but drivers still have
to interpret the CONFIG_NVRAM symbol consistently regardless of platform.
In this patch and the subsequent fbdev driver patch, the convention is
adopted across all relevant platforms whereby NVRAM functionality gets
enabled in a given device driver when the nvram misc device is built-in
or when both drivers are modules.

One of the more common cases of allocation size calculations is finding the
size of a structure that has a zero-sized array at the end, along with memory
for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can now
use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);
This code was detected with the help of Coccinelle.

Change snprintf to scnprintf. There are generally two cases where using
snprintf causes problems.
1) Uses of size += snprintf(buf, SIZE - size, fmt, ...)
In this case, if snprintf would have written more characters than what the
buffer size (SIZE) is, then size will end up larger than SIZE. In later
uses of snprintf, SIZE - size will result in a negative number, leading
to problems. Note that size might already be too large by using
size = snprintf before the code reaches a case of size += snprintf.
2) If size is ultimately used as a length parameter for a copy back to user
space, then it will potentially allow for a buffer overflow and information
disclosure when size is greater than SIZE. When the size is used to index
the buffer directly, we can have memory corruption. This also means when
size = snprintf... is used, it may also cause problems since size may become
large. Copying to userspace is mitigated by the HARDENED_USERCOPY kernel
configuration.
The solution to these issues is to use scnprintf which returns the number of
characters actually written to the buffer, so the size variable will never
exceed SIZE.
