ioctl_list - 在Linux/i386 中內核的ioctl調用列表

描述

This is Ioctl List 1.3.27, a list of ioctl calls in Linux/i386 kernel 1.3.27. It contains 421 ioctls from /usr/include/{asm,linux}/*.h. For each ioctl, its numerical value, its name, and its argument type are given.

An argument type of ’const struct foo *’ means the argument is input to the kernel. ’struct foo *’ means the kernel outputs the argument. If the kernel uses the argument for both input and output, this is marked with // I-O.

一些讀寫控制採取更多參數或返回超過一個單一的結構更多的值。這些標記//以上，進一步在一個單獨的部分記錄。

這個列表是非常不完整的。請電郵修訂和批註，Mail: <[email protected]>.

IOCTL結構

ioctl命令的值是32位的常數。原則上這些常量是完全任意的，但人們都試圖建立一些結構放進去。

The old Linux situation was that of mostly 16-bit constants, where the last byte is a serial number, and the preceding byte(s) give a type indicating the driver. Sometimes the major number was used: 0x03 for the HDIO_* ioctls, 0x06 for the LP* ioctls. And sometimes one or more ASCII letters were used. For example, TCGETS has value 0x00005401, with 0x54 = ’T’ indicating the terminal driver, and CYGETTIMEOUT has value 0x00435906, with 0x43 0x59 = ’C’ ’Y’ indicating the cyclades driver.

Later (0.98p5) some more information was built into the number. One has 2 direction bits (00: none, 01: write, 10: read, 11: read/write) followed by 14 size bits (giving the size of the argument), followed by an 8-bit type (collecting the ioctls in groups for a common purpose or a common driver), and an 8-bit serial number.

The macros describing this structure live in <asm/ioctl.h> and are _IO(type,nr) and {_IOR,_IOW,_IOWR}(type,nr,size). They use sizeof(size) so that size is a misnomer here: this third parameter is a data type.

Note that the size bits are very unreliable: in lots of cases they are wrong, either because of buggy macros using sizeof(sizeof(struct)), or because of legacy values.

Thus, it seems that the new structure only gave disadvantages: it does not help in checking, but it causes varying values for the various architectures.

返回值

Decent ioctls return 0 on success and -1 on error, while any output value is stored via the argument. However, quite a few ioctls in fact return an output value. This is not yet indicated below.

Some ioctl’s take a pointer to a 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 \* // Duplicate ioctls 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
