NAME

ioctl_list-Linux/i386カーネルのioctl呼び出しのリスト

説明

これは、Linux/i386カーネル1.3.27のioctl呼び出しのリストであるIoctl List 1.3.27です。/usr/include/\{asm,linux}/*.hから421個のioctlが含まれています。 各ioctlについて、その数値、名前、および引数タイプが指定されます。

引数タイプ「const struct foo *」は、引数がカーネルに入力されることを意味します。 「struct foo *」は、カーネルが引数を出力することを意味します。 カーネルが入力と出力の両方に引数を使用する場合、これは//I-Oでマークされます。

いくつかのioctlは、単一の構造よりも多くの引数を取るか、より多くの値を返します。 これらは//より多くマークされ、別のセクションでさらに文書化されます。

このリストは非常に不完全です。 <mec@duracef.shout.net>に変更とコメントをメールしてください。

IOCTL構造

Ioctlコマンドの値は32ビットの定数です。 原則として、これらの定数は完全にarbitrary意的ですが、人々はそれらに何らかの構造を構築しようとしました。

古いLinuxの状況は、ほとんどが16ビットの定数で、最後のバイトはシリアル番号で、前のバイトはドライバーを示すタイプを与えていました。 時々メジャー番号が使用されました：HDIO_ ioctlの場合は0x03、LP ioctlの場合は0x06。 また、時には1つ以上のASCII文字が使用されました。 たとえば、TCGETSの値は0x00005401で、0x54 = 'T’はターミナルドライバーを示し、CYGETTIMEOUTの値は0x00435906を持ち、0x43 0x59 = 'C' 'Y’はキクラデスドライバーを示します。

後で（0.98p5）さらにいくつかの情報が数字に組み込まれました。 1つは2つの方向ビット（00：なし、01：書き込み、10：読み取り、11：読み取り/書き込み）に続き、14サイズビット（引数のサイズを指定）、8ビットタイプ（ioctlを収集する）共通の目的または共通のドライバーのグループ）、および8ビットのシリアル番号。

この構造を記述するマクロは<asm/ioctl.h>にあり、IO（type、nr）および\ { IOR、_IOW、_IOWR}（type、nr、size）です。 ここではsizeof（size）を使用しているため、ここではサイズが誤った呼び名になります。この3番目のパラメーターはデータ型です。

サイズビットは非常に信頼性が低いことに注意してください。多くの場合、sizeof（sizeof（struct））を使用するバグのあるマクロのため、またはレガシー値のために、それらは間違っています。

したがって、新しい構造には欠点があるだけで、チェックには役に立たないが、さまざまなアーキテクチャで値が変化するように思われる。

返り値

適切なioctlは、成功すると0を返し、エラー時には-1を返しますが、出力値は引数を介して保存されます。 ただし、実際にはかなりの数のioctlが出力値を返します。 これはまだ以下に示されていません。

structure which contains additional pointers. These are documented here in alphabetical order. CDROMREADAUDIO takes an input pointer ’const struct cdrom_read_audio *’. The ’buf’ field points to an output buffer of length ’nframes *CD_FRAMESIZE_RAW’. CDROMREADCOOKED, CDROMREADMODE1, CDROMREADMODE2, and CDROMREADRAW take an input pointer ’const struct cdrom_msf* ’. They use the same pointer as an output pointer to ’char []’. The length varies by request. For CDROMREADMODE1, most drivers use ’CD_FRAMESIZE’, but the Optics Storage driver uses ’OPT_BLOCKSIZE’ instead (both have the numerical value 2048).          CDROMREADCOOKED             char [CD_FRAMESIZE]          CDROMREADMODE1              char [CD_FRAMESIZE or OPT_BLOCKSIZE]          CDROMREADMODE2              char [CD_FRAMESIZE_RAW0]          CDROMREADRAW                char [CD_FRAMESIZE_RAW] EQL_ENSLAVE, EQL_EMANCIPATE, EQL_GETSLAVECFG, EQL_SETSLAVECFG, EQL_GETMASTERCFG, and EQL_SETMASTERCFG take a ’struct ifreq *’. The ’ifr_data’ field is a pointer to another structure as follows:          EQL_ENSLAVE                 const struct slaving_request *          EQL_EMANCIPATE              const struct slaving_request *          EQL_GETSLAVECFG             struct slave_config *           //I-O          EQL_SETSLAVECFG             const struct slave_config *          EQL_GETMASTERCFG            struct master_config *          EQL_SETMASTERCFG            const struct master_config * FDRAWCMD takes a ’struct floppy raw_cmd *’. If ’flags & FD_RAW_WRITE’ is non-zero, then ’data’ points to an input buffer of length ’length’. If ’flags & FD_RAW_READ’ is non-zero, then ’data’ points to an output buffer of length ’length’. GIO_FONTX and PIO_FONTX take a ’struct console_font_desc *’ or a ’const struct console_font_desc *’, respectively. ’chardata’ points to a buffer of ’char [charcount]’. This is an output buffer for GIO_FONTX and an input buffer for PIO_FONTX. GIO_UNIMAP and PIO_UNIMAP take a ’struct unimapdesc *’ or a ’const struct unimapdesc *’, respectively. ’entries’ points to a buffer of ’struct unipair [entry_ct]’. This is an output buffer for GIO_UNIMAP and an input buffer for PIO_UNIMAP. KDADDIO, KDDELIO, KDDISABIO, and KDENABIO enable or disable access to I/O ports. They are essentially alternate interfaces to ’ioperm’. KDMAPDISP and KDUNMAPDISP enable or disable memory mappings or I/O port access. They are not implemented in the kernel. SCSI_IOCTL_PROBE_HOST takes an input pointer ’const int *’, which is a length. It uses the same pointer as an output pointer to a ’char []’ buffer of this length. SIOCADDRT and SIOCDELRT take an input pointer whose type depends on the protocol:          Most protocols              const struct rtentry *          AX.25                       const struct ax25_route *          NET/ROM                     const struct nr_route_struct * SIOCGIFCONF takes a ’struct ifconf *’. The ’ifc_buf’ field points to a buffer of length ’ifc_len’ bytes, into which the kernel writes a list of type ’struct ifreq []’. SIOCSIFHWADDR takes an input pointer whose type depends on the protocol:          Most protocols              const struct ifreq *          AX.25                       const char [AX25_ADDR_LEN] TIOCLINUX takes a ’const char *’. It uses this to distinguish several independent sub-cases. In the table below, ’N + foo’ means ’foo’ after an N-byte pad. ’struct selection’ is implicitly defined in ’drivers/char/selection.c’          TIOCLINUX-2                 1 + const struct selection *          TIOCLINUX-3                 void          TIOCLINUX-4                 void          TIOCLINUX-5                 4 + const struct { long [8]; } *          TIOCLINUX-6                 char *          TIOCLINUX-7                 char *          TIOCLINUX-10                1 + const char * This list does not include ioctls in the range SIOCDEVPRIVATE and SIOCPROTOPRIVATE. 0x00000001 FDSETPRM                    FIBMAP 0x00000002 FDDEFPRM                    FIGETBSZ 0x00005382 CDROMAUDIOBUFSIZ            SCSI_IOCTL_GET_IDLUN 0x00005402 SNDCTL_TMR_START            TCSETS 0x00005403 SNDCTL_TMR_STOP             TCSETSW 0x00005404 SNDCTL_TMR_CONTINUE         TCSETSF
