Since CMA is getting used more widely, it's more important to
keep monitoring CMA statistics for system health since it's
directly related to user experience.
This patch introduces sysfs statistics for CMA, in order to provide
some basic monitoring of the CMA allocator.

We have a usecase where we want to audit symbol names (if available) in
callback registration hooks. (ex: fentry/nf_register_net_hook)
A few months back, I proposed a bpf_kallsyms_lookup series but it was
decided in the reviews that a more generic helper, bpf_snprintf, would
be more useful.
This
Two helpers (trace_printk and seq_printf) have very similar
implementations of format string parsing and a third one is coming
(snprintf). To avoid code duplication and make the code easier to
maintain, this moves the operations associated with format string
parsing (validation and argument
When initializing the __param array with a one liner, if all args are
const, the initial array value will be placed in the rodata section but
because libbpf does not support relocation in the rodata section, any
pointer in this array will stay NULL.

This type provides the guarantee that an argument is going to be a const
pointer to somewhere in a read-only map value. It also checks that this
pointer is followed by a zero character before the end of the map value.

Linux supports KAsan for VMALLOC since commit 3c5c3cfb9ef4da9
("kasan: support backing vmalloc space with real shadow memory")
Acroding to how x86 ported it [1], they early allocated p4d and pgd,
but in arm64 I just simulate how KAsan supports MODULES_VADDR in arm64
by not to populate the
Arm64 provides defined macro for KERNEL_START and KERNEL_END,

After KASAN_VMALLOC works in arm64, we can randomize module region
into vmalloc area now.
Test:
VMALLOC area ffc01000 fffdf000
before the patch:

after the patch:
Linux support KAsan for VMALLOC since commit 3c5c3cfb9ef4da9
("kasan: support backing vmalloc space with real shadow memory")
Like how the MODULES_VADDR does now, just not to early populate
the VMALLOC_START between VMALLOC_END.
Before:
MODULE_VADDR: no mapping, no zero shadow at init
Before this patch, someone who wants to use VMAP_STACK when
KASAN_GENERIC enabled must explicitly select KASAN_VMALLOC.

ok, but could you please review this patch?

Hi,
Need to fix the work as following:
s/extconn/extcon
And I'd like you to use the more correct patch title like the following example:
"extcon: Use resource-managed function for delayed work"
Thanks,

Add an API that can parse the build ID out of a buffer, instead of a
vma, to support printing a kernel module's build ID for stack traces.

Add vmlinux_build_id() so that callers can print a hex format string
representation of the running kernel's build ID. This will be used in
the kdump and dump_stack code so that developers can easily locate the
vmlinux debug symbols for a crash/stacktrace.

This series adds the kernel's build ID[1] to the stacktrace header printed
in oops messages, warnings, etc. and the build ID for any module that
appears in the stacktrace after the module name. The goal is to make the
stacktrace more self-contained and descriptive by including the relevant
build
Let's use the new printk format to print the stacktrace entry when
printing a backtrace to the kernel logs. This will include any module's
build ID[1] in it so that offline/crash debugging can easily locate the
debuginfo for a module via something like debuginfod[2].

Add "auto" to the usage message so that it's a little clearer that you
can pass "auto" as the second argument. When passing "auto" the script
tries to find the base path automatically instead of requiring it be
passed on the commandline. Also use [] to indicate the
variable argument and that it is

Add the running kernel's build ID[1] to the stacktrace information

We can use the vmlinux_build_id() helper here now instead of open coding
it. This consolidates code and possibly avoids calculating the build ID
twice in the case of a crash with a stacktrace.

Sometimes if you're using tools that have linked things improperly or
have new features/sections that older tools don't expect you'll see
warnings printed to stderr. We don't really care about these warnings,
so let's just silence these messages to cleanup output of this script.

Now that stacktraces contain the build ID information we can update this
script to use debuginfod-find to locate the debuginfo for the vmlinux
and modules automatically. This can replace the existing code that
requires specifying a path to vmlinux or tries to find the vmlinux and
modules
