Subject: [PATCH v2] Documentation: remove magic number doc
Date: Thu, 8 Sep 2022 01:11:09 +0200 [thread overview]
Message-ID: <20220907231109.htnfxzmr6wkuhn2v@tarta.nabijaczleweli.xyz> (raw)

[-- Attachment #1: Type: text/plain, Size: 47045 bytes --]
The entire file blames back to the start of git
(minus whitespace from the RST translation and a typo fix):
* there are changelog comments for March 1994 through to Linux 2.5.74
* struct tty_ldisc is two pointers nowadays, so naturally no magic
* GDA_MAGIC is defined but unused, and it's been this way
since start-of-git
* M3_CARD_MAGIC isn't defined, because
commit d56b9b9c464a10ab1ee51a4c6190a2b57b8ef7a6 ("[PATCH] The
scheduled removal of some OSS drivers")
removed the entire driver in 2006
* CS_CARD_MAGIC likewise since
commit b5d425c97f7d4e92151167b01ca038e7853c6b37 ("more scheduled OSS
driver removal") in 2007
* KMALLOC_MAGIC and VMALLOC_MAGIC were removed in
commit e38e0cfa48ac38f4fe24453d2523852467c95b21 ("[ALSA] Remove
kmalloc wrappers"), six months after start of git
* SLAB_C_MAGIC has never even appeared in git
(removed in in 2.4.0-test3pre6)
At a glance, the only ones still in use are in code mostly untouched
since git (TTY, SLIP, SCSI (drivers/scsi/{arm/queue.c,ncr53c8xx.c}),
&c., but not PPP or PTY (neither exist now)).
A rough estimate of magic numbers in the kernel may be obtained via
# git grep define | grep '_MAGIC\b' |
grep -ve IOC -e ^tools/ -e '_IO[(WR]' -e _SUPER | wc -l
780
there is, of course, a few other meanings of magic here,
but a random sampling of SR_EEPROM_MAGIC, L2TP_TUNNEL_MAGIC,
and MD_SB_MAGIC showed they are all used like magic-number.rst describes
and are not in it
By all accounts, it seems magic-number.rst is a low-value historical
relic at best and misleading cruft at worst

-Linux magic numbers
-===================
-
-This file is a registry of magic numbers which are in use. When you
-add a magic number to a structure, you should also add it to this
-file, since it is best if the magic numbers used by various structures
-are unique.
-
-It is a **very** good idea to protect kernel data structures with magic
-numbers. This allows you to check at run time whether (a) a structure
-has been clobbered, or (b) you've passed the wrong structure to a
-routine. This last is especially useful --- particularly when you are
-passing pointers to structures via a void * pointer. The tty code,
-for example, does this frequently to pass driver-specific and line
-discipline-specific structures back and forth.
-
-The way to use magic numbers is to declare them at the beginning of
-the structure, like so::
-
- struct tty_ldisc {
- int magic;
- ...
- };
-
-Please follow this discipline when you are adding future enhancements
-to the kernel! It has saved me countless hours of debugging,
-especially in the screwy cases where an array has been overrun and
-structures following the array have been overwritten. Using this
-discipline, these cases get detected quickly and safely.

-Changelog::
-
- Theodore Ts'o
- 31 Mar 94
-
- The magic table is current to Linux 2.1.55.
-
- Michael Chastain
- <mailto:mec@shout.net>
- 22 Sep 1997
-
- Now it should be up to date with Linux 2.1.112. Because
- we are in feature freeze time it is very unlikely that
- something will change before 2.2.x. The entries are
- sorted by number field.
-
- Krzysztof G. Baranowski
- <mailto: kgb@knm.org.pl>
- 29 Jul 1998
-
- Updated the magic table to Linux 2.5.45. Right over the feature freeze,
- but it is possible that some new magic numbers will sneak into the
- kernel before 2.6.x yet.
-
- Petr Baudis
- <pasky@ucw.cz>
- 03 Nov 2002
-
- Updated the magic table to Linux 2.5.74.

-I numeri magici di Linux
-========================
-
-Questo documento è un registro dei numeri magici in uso. Quando
-aggiungete un numero magico ad una struttura, dovreste aggiungerlo anche
-a questo documento; la cosa migliore è che tutti i numeri magici usati
-dalle varie strutture siano unici.
-
-È **davvero** un'ottima idea proteggere le strutture dati del kernel con
-dei numeri magici. Questo vi permette in fase d'esecuzione di (a) verificare
-se una struttura è stata malmenata, o (b) avete passato a una procedura la
-struttura errata. Quest'ultimo è molto utile - particolarmente quando si passa
-una struttura dati tramite un puntatore void \*. Il codice tty, per esempio,
-effettua questa operazione con regolarità passando avanti e indietro le
-strutture specifiche per driver e discipline.
-
-Per utilizzare un numero magico, dovete dichiararlo all'inizio della struttura
-dati, come di seguito::
-
- struct tty_ldisc {
- int magic;
- ...
- };
-
-Per favore, seguite questa direttiva quando aggiungerete migliorie al kernel!
-Mi ha risparmiato un numero illimitato di ore di debug, specialmente nei casi
-più ostici dove si è andati oltre la dimensione di un vettore e la struttura
-dati che lo seguiva in memoria è stata sovrascritta. Seguendo questa
-direttiva, questi casi vengono identificati velocemente e in sicurezza.

-Linux 魔术数
-============
-
-这个文件是有关当前使用的魔术值注册表。当你给一个结构添加了一个魔术值，你也应该把这个魔术值添加到这个文件，因为我们最好把用于各种结构的魔术值统一起来。
-
-使用魔术值来保护内核数据结构是一个非常好的主意。这就允许你在运行期检查(a)一个结构是否已经被攻击，或者(b)你已经给一个例行程序通过了一个错误的结构。后一种情况特别地有用---特别是当你通过一个空指针指向结构体的时候。tty源码，例如，经常通过特定驱动使用这种方法并且反复地排列特定方面的结构。
-
-使用魔术值的方法是在结构的开始处声明的，如下::
-
- struct tty_ldisc {
- int magic;
- ...
- };
-
-当你以后给内核添加增强功能的时候，请遵守这条规则！这样就会节省数不清的调试时间，特别是一些古怪的情况，例如，数组超出范围并且重新写了超出部分。遵守这个规则，这些情况可以被快速地，安全地避免。
