The Linux version of the 9p server is now maintained under the npfs project
|
||||
on sourceforge (http://sourceforge.net/projects/npfs).
|
||||
Our current recommendation is to use Inferno (http://www.vitanuova.com/inferno)
|
||||
as the 9p server. You can start a 9p server under Inferno by issuing the
|
||||
following command:
|
||||
; styxlisten -A tcp!*!564 export '#U*'
|
||||
|
||||
The -A specifies an unauthenticated export. The 564 is the port # (you may
|
||||
have to choose a higher port number if running as a normal user). The '#U*'
|
||||
specifies exporting the root of the Linux name space. You may specify a
|
||||
subset of the namespace by extending the path: '#U*'/tmp would just export
|
||||
/tmp. For more information, see the Inferno manual pages covering styxlisten
|

and export.

The Magic SysRQ system works by registering key operations against a key op

lookup table, which is defined in 'drivers/char/sysrq.c'. This key table has

a number of operations registered into it at compile time, but is mutable,

and 4 functions are exported for interface to it: __sysrq_lock_table,
|
||||
__sysrq_unlock_table, __sysrq_get_key_op, and __sysrq_put_key_op. The

||||
functions __sysrq_swap_key_ops and __sysrq_swap_key_ops_nolock are defined
|
||||
in the header itself, and the REGISTER and UNREGISTER macros are built from
|
||||
these. More complex (and dangerous!) manipulations of the table are possible
|
||||
using these functions, but you must be careful to always lock the table before
|
||||
you read or write from it, and to unlock it again when you are done. (And of
|

course, to never ever leave an invalid pointer in the table). Null pointers in

the table are always safe :)
