v1->v2:
  - Sort arrays at build time
  - Merge nt_errs to ntstatus_to_dos_map
  - Check if arrays are sorted in smb1_init_maperror()

v1: https://lore.kernel.org/linux-cifs/20251208062100.3268777-1-chenxiaosong.chenxiaosong@linux.dev/

Add comments to NT_STATUS definitions in nterr.h indicating the
corresponding DOS error class and code.

To ensure formatting consistency and facilitate automated processing,
existing human-readable comments in nterr.h were first moved to the
line preceding the #define statements.

This provides the source data for generating sorted mapping tables,
allowing the implementation of binary search for faster error mapping
lookups in later commits.

The mapping data is extracted from the existing manual
ntstatus_to_dos_map[] array in smb1maperror.c using the following
python script:

	#!/usr/bin/env python3
	import re
	import os

	MAP_FILE = "fs/smb/client/smb1maperror.c"
	NTERR_FILE = "fs/smb/client/nterr.h"

	def move_comments(file_path):
	    """
	    Moves existing inline comments (/* ... */ or // ...) to
	    the preceding line to ensure formatting consistency.
	    """
	    if not os.path.exists(file_path):
		return
	    with open(file_path, "r") as f:
		lines = f.readlines()
	    new_lines = []
	    # Match #define statements with inline comments
	    re_str = r'^(\s*#define\s+[A-Za-z0-9_]+\s+.*?)\s*(/\*.*?\*/|//.*)$'
	    pattern = re.compile(re_str)
	    for line in lines:
		match = pattern.match(line.rstrip())
		if match:
		    define_part, comment_part = match.groups()
		    indent = " " * (len(line) - len(line.lstrip()))
		    # Move old comment to previous line
		    new_lines.append(indent + comment_part + "\n")
		    # Keep the define part
		    new_lines.append(define_part.rstrip() + "\n")

	    for line in lines:
		stripped = line.strip()
		if stripped.startswith("#define NT_STATUS_"):
		    # Remove any existing // comments before re-annotating
		    base_line = re.sub(r'\s*//.*$', '', line.rstrip())
		    parts = base_line.split()
		    if len(parts) >= 2:
			name = parts[1]
			# Append comment, ensuring proper alignment
			if name == "NT_STATUS_OK":
			    line = f"{base_line}\t// SUCCESS, 0\n"

			else:

  Cc: linux-cifs, Huiwen He

From: Huiwen He <hehuiwen@kylinos.cn>

Introduce `gen_smb1_mapping` script to autogenerate the NT status to
DOS error mapping table for SMB1. This script parses nterr.h to
generate smb1_mapping_table.c, which is then directly included as
the content of the ntstatus_to_dos_map[] array at compile time.

The generated array is numerically sorted during the build process to
ensure a consistent structure, providing the necessary groundwork for
future introduction of binary search lookups.

  Cc: linux-cifs, Huiwen He

From: Huiwen He <hehuiwen@kylinos.cn>

The ntstatus_to_dos_map[] array now contains the NT error strings,
making the nt_errs[] array redundant.

Introduce `struct ntstatus_to_dos_err` instead of an anonymous struct.
This allows cifs_print_status() to look up error strings directly
from a single table.

Remove nterr.c, as nt_errs[] was its only functional content.

  Cc: linux-cifs, Huiwen He

From: Huiwen He <hehuiwen@kylinos.cn>

Refactor ntstatus_to_dos() to return a pointer to the mapping entry
instead of using output parameters. This allows callers to access all
fields of the entry directly.

In map_smb_to_linux_error(), integrate the printing logic directly
to avoid redundant lookups previously performed by cifs_print_status(),
which is now removed.

From: Huiwen He <hehuiwen@kylinos.cn>

The ntstatus_to_dos_map[] table is sorted now. Replace the linear search
with binary search to improve lookup performance.

Also remove the sentinel entry as it is no longer needed with ARRAY_SIZE().

Although the array is sorted at build time, verify the ordering again
when cifs.ko is loaded to avoid potential regressions introduced by
future script changes.

We are going to define 3 functions to check the sort results, introduce the
macro DEFINE_CHECK_SORT_FUNC() to reduce duplicate code.

Check whether all elements can be correctly found in the array.

Introduce CONFIG_SMB1_KUNIT_TESTS for smb1maperror_test.ko since
smb1maperror.o is only built when CONFIG_CIFS_ALLOW_INSECURE_LEGACY
is enabled.

We are going to define 3 functions to check the search results, introduce

From: Huiwen He <hehuiwen@kylinos.cn>

Annotate SMB1 error definitions in smberr.h with their corresponding
POSIX error codes.

To facilitate automated processing and ensure consistent formatting,
existing inline comments (/* ... */) in smberr.h were first moved to
the lines preceding the #define statements.

This provides the source data for generating sorted mapping tables,
allowing the implementation of binary search for faster error mapping
lookups in later commits.

The annotations were performed based on the manual
mapping_table_ERRDOS[] and mapping_table_ERRSRV[] arrays in
smb1maperror.c using the following python script:

	#!/usr/bin/env python3
	import re
	import os

	MAP_FILE = "fs/smb/client/smb1maperror.c"
	SMBERR_FILE = "fs/smb/client/smberr.h"

			r'\{\s*([A-Za-z0-9_]+)\s*,\s*'
			r'(-[A-Z0-9_]+)\s*\}'
		    )
		    entries = re.findall(entry_pattern, match.group(1))

  Cc: linux-cifs, Huiwen He

From: Huiwen He <hehuiwen@kylinos.cn>

Extend the `gen_smb1_mapping` script to support generating sorted POSIX
error mapping tables for both ERRDOS and ERRSRV classes at compile time.

The script parses annotations from smberr.h to generate smb1_err_dos_map.c
and smb1_err_srv_map.c, which are included as the contents of the arrays
mapping_table_ERRDOS[] and mapping_table_ERRSRV[], respectively.

This ensures that the mapping logic remains synchronized with the source
headers and prepares for faster error lookups using binary search in the
future.

  Cc: linux-cifs, Huiwen He

From: Huiwen He <hehuiwen@kylinos.cn>

Currently, map_smb_to_linux_error() uses linear searches for both
mapping_table_ERRDOS[] and mapping_table_ERRSRV[].

Refactor this by introducing a helper function smb1_map_to_posix() that
implements binary search(as the tables are sorted). This improves lookup
performance and reduces code duplication.

Also remove the sentinel entries from the mapping tables as they are no
longer needed with ARRAY_SIZE().

Although the arrays are sorted at build time, verify the ordering again
when cifs.ko is loaded to avoid potential regressions introduced by
future script changes.

Hi Huiwen and Youling,

I wrote some additional temporary test cases (not intended to be merged):
https://chenxiaosong.com/en/smb1maperror-test.html

These test cases copy the three arrays from before the patchset and 
compare them with those after the patchset. The test cases failed, 
please fix them.

Thanks,
ChenXiaoSong <chenxiaosong@kylinos.cn>
