[PATCH 3/7] asinfo: Introduce static query tool asinfo
|
From: Edgar K. <edg...@vi...> - 2017-12-10 13:56:48
|
The main purpose of this query tool is to present all information concluded
at sysent.h files in a convenient way.
The asinfo tool has the following staged architecture:
(command dispatcher)->(architecture dispatcher)->
(abi dispatcher)->(system call dispatcher).
Each dispatcher accepts proccesed data from the previous one.
This point can be illustrated by the following example:
$ asinfo --get-arch --get-sname write
First of all, arch_dispatcher will return the current architecture, based on
uname return value, after that in case of no options for abi_dispatcher,
it perceives empty parameter as get-abi parameter and returns ABI mode set at
compile time of strace package. Therefore, syscall_dispatcher accepts this
architecture/ABI and works with specific set of system calls. It is worth
mentioning that it supports all architectures/ABIs supported by strace.
Also, tool can work in multi-arch mode. for instance:
$ ./tools/asinfo/asinfo --set-arch mips64,mips --set-abi n64,all
--get-snum 100,8,ipc
For more info, use asinfo -h.
* Makefile.am (SUBDIRS): Add tools directory.
* configure.ac (AC_CONFIG_FILES): Add Makefiles.
* tools/Makefile.am: New file.
* tools/asinfo/Makefile.am: Likewise.
* tools/asinfo/dispatchers.h: New file. Prototype abi_dispatcher,
arch_dispatcher, and syscall_dispatcher.
* tools/asinfo/dispatchers.c: New file. Implement them.
* tools/asinfo/error_interface.h: New file. Introduce error_service to
improve informativeness of output errors. Prototype methods to work with
error_service.
* tools/asinfo/error_interface.c: New file. Implement it.
* tools/asinfo/arch_interface.h: New file. Introduce struct
arch_descriptor. Introduce arch_service. Prototype methods to simplify
work with the arch_service.
* tools/asinfo/arch_interface.c: New file. Implement it.
* tools/asinfo/syscall_interface.h: New file. Introduce syscall_service.
Prototype methods to simplify work with syscall_service.
* tools/asinfo/syscall_interface.c: New file. Implement it.
* tools/asinfo/request_msgs.h: New file. Introduce main requests.
* tools/asinfo/asinfo.c: New file. Implement support of all options.
Implement usage. Implement version.
* tools/asinfo/arch_definitions.h: New file. Introduce useful storage
for architectures.
* tools/asinfo/arch_includes.h: New file.
* tools/asinfo/personalities.h: Likewise.
* tools/asinfo/.gitignore: Likewise.
