From 53c2bd679017277fce41101ae86ab51a234c29f7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?=D0=BD=D0=B0=D0=B1?= Date: Fri, 16 Sep 2022 00:38:46 +0200 Subject: [PATCH] a.out: remove define-only CMAGIC, previously magic number MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The last user was removed in 5.1 in commit 08300f4402ab ("a.out: remove core dumping support") but this is part of the UAPI headers, so this may want to either wait until a.out is removed entirely, or be removed from the magic number doc and silently remain in the header A cursory glance on DCS didn't show any user code actually using this value Found with grep MAGIC Documentation/process/magic-number.rst | while read -r mag _; do git grep -wF "$mag" | grep -ve '^Documentation.*magic-number.rst:' \ -qe ':#define '"$mag" || git grep -wF "$mag" | while IFS=: read -r f _; do sed -i '/\b'"$mag"'\b/d' "$f"; done ; done Signed-off-by: Ahelenia Ziemiańska Link: https://lore.kernel.org/r/9cbea062df7125ef43e2e0b2a67ede6ad1c5f27e.1663280877.git.nabijaczleweli@nabijaczleweli.xyz Signed-off-by: Greg Kroah-Hartman --- Documentation/process/magic-number.rst | 1 - Documentation/translations/it_IT/process/magic-number.rst | 1 - Documentation/translations/zh_CN/process/magic-number.rst | 1 - Documentation/translations/zh_TW/process/magic-number.rst | 1 - include/uapi/linux/a.out.h | 3 --- 5 files changed, 7 deletions(-) diff --git a/Documentation/process/magic-number.rst b/Documentation/process/magic-number.rst index eb2db36..f48c6c6 100644 --- a/Documentation/process/magic-number.rst +++ b/Documentation/process/magic-number.rst @@ -69,7 +69,6 @@ Changelog:: Magic Name Number Structure File ===================== ================ ======================== ========================================== PG_MAGIC 'P' pg_{read,write}_hdr ``include/linux/pg.h`` -CMAGIC 0x0111 user ``include/linux/a.out.h`` HDLC_MAGIC 0x239e n_hdlc ``drivers/char/n_hdlc.c`` APM_BIOS_MAGIC 0x4101 apm_user ``arch/x86/kernel/apm_32.c`` FASYNC_MAGIC 0x4601 fasync_struct ``include/linux/fs.h`` diff --git a/Documentation/translations/it_IT/process/magic-number.rst b/Documentation/translations/it_IT/process/magic-number.rst index 86ef479..27f6013 100644 --- a/Documentation/translations/it_IT/process/magic-number.rst +++ b/Documentation/translations/it_IT/process/magic-number.rst @@ -75,7 +75,6 @@ Registro dei cambiamenti:: Nome magico Numero Struttura File ===================== ================ ======================== ========================================== PG_MAGIC 'P' pg_{read,write}_hdr ``include/linux/pg.h`` -CMAGIC 0x0111 user ``include/linux/a.out.h`` HDLC_MAGIC 0x239e n_hdlc ``drivers/char/n_hdlc.c`` APM_BIOS_MAGIC 0x4101 apm_user ``arch/x86/kernel/apm_32.c`` FASYNC_MAGIC 0x4601 fasync_struct ``include/linux/fs.h`` diff --git a/Documentation/translations/zh_CN/process/magic-number.rst b/Documentation/translations/zh_CN/process/magic-number.rst index cbefdcb..520cc5c 100644 --- a/Documentation/translations/zh_CN/process/magic-number.rst +++ b/Documentation/translations/zh_CN/process/magic-number.rst @@ -58,7 +58,6 @@ Linux 魔术数 魔术数名 数字 结构 文件 ===================== ================ ======================== ========================================== PG_MAGIC 'P' pg_{read,write}_hdr ``include/linux/pg.h`` -CMAGIC 0x0111 user ``include/linux/a.out.h`` HDLC_MAGIC 0x239e n_hdlc ``drivers/char/n_hdlc.c`` APM_BIOS_MAGIC 0x4101 apm_user ``arch/x86/kernel/apm_32.c`` FASYNC_MAGIC 0x4601 fasync_struct ``include/linux/fs.h`` diff --git a/Documentation/translations/zh_TW/process/magic-number.rst b/Documentation/translations/zh_TW/process/magic-number.rst index 7fd6e49..7d6debd 100644 --- a/Documentation/translations/zh_TW/process/magic-number.rst +++ b/Documentation/translations/zh_TW/process/magic-number.rst @@ -61,7 +61,6 @@ Linux 魔術數 魔術數名 數字 結構 文件 ===================== ================ ======================== ========================================== PG_MAGIC 'P' pg_{read,write}_hdr ``include/linux/pg.h`` -CMAGIC 0x0111 user ``include/linux/a.out.h`` HDLC_MAGIC 0x239e n_hdlc ``drivers/char/n_hdlc.c`` APM_BIOS_MAGIC 0x4101 apm_user ``arch/x86/kernel/apm_32.c`` FASYNC_MAGIC 0x4601 fasync_struct ``include/linux/fs.h`` diff --git a/include/uapi/linux/a.out.h b/include/uapi/linux/a.out.h index 5fafde3..bb15da9 100644 --- a/include/uapi/linux/a.out.h +++ b/include/uapi/linux/a.out.h @@ -70,9 +70,6 @@ enum machine_type { The first page is unmapped to help trap NULL pointer references */ #define QMAGIC 0314 -/* Code indicating core file. */ -#define CMAGIC 0421 - #if !defined (N_BADMAG) #define N_BADMAG(x) (N_MAGIC(x) != OMAGIC \ && N_MAGIC(x) != NMAGIC \ -- 2.7.4
