# This file is used to automatically generate bionic's system call stubs. # # Each non-blank, non-comment line has the following format: # # return_type func_name[|alias_list][:syscall_name[:socketcall_id]]([parameter_list]) arch_list # # where: # arch_list ::= "all" | arch+ # arch ::= "arm" | "arm64" | "mips" | "mips64" | "x86" | "x86_64" # # Note: # - syscall_name corresponds to the name of the syscall, which may differ from # the exported function name (example: the exit syscall is implemented by the _exit() # function, which is not the same as the standard C exit() function which calls it) # # - alias_list is optional comma separated list of function aliases. # # - The call_id parameter, given that func_name and syscall_name have # been provided, allows the user to specify dispatch style syscalls. # For example, socket() syscall on i386 actually becomes: # socketcall(__NR_socket, 1, *(rest of args on stack)). # # - Each parameter type is assumed to be stored in 32 bits. # # This file is processed by a python script named gensyscalls.py. int execve(const char*, char* const*, char* const*) all uid_t getuid:getuid32() arm,x86 uid_t getuid:getuid() arm64,mips,mips64,x86_64 gid_t getgid:getgid32() arm,x86 gid_t getgid:getgid() arm64,mips,mips64,x86_64 uid_t geteuid:geteuid32() arm,x86 uid_t geteuid:geteuid() arm64,mips,mips64,x86_64 gid_t getegid:getegid32() arm,x86 gid_t getegid:getegid() arm64,mips,mips64,x86_64 uid_t getresuid:getresuid32(uid_t* ruid, uid_t* euid, uid_t* suid) arm,x86 uid_t getresuid:getresuid(uid_t* ruid, uid_t* euid, uid_t* suid) arm64,mips,mips64,x86_64 gid_t getresgid:getresgid32(gid_t* rgid, gid_t* egid, gid_t* sgid) arm,x86 gid_t getresgid:getresgid(gid_t* rgid, gid_t* egid, gid_t* sgid) arm64,mips,mips64,x86_64 ssize_t readahead(int, off64_t, size_t) all int getgroups:getgroups32(int, gid_t*) arm,x86 int getgroups:getgroups(int, gid_t*) arm64,mips,mips64,x86_64 pid_t getpgid(pid_t) all pid_t getppid() all pid_t getsid(pid_t) all pid_t setsid() all int setgid:setgid32(gid_t) arm,x86 int setgid:setgid(gid_t) arm64,mips,mips64,x86_64 int setuid:setuid32(uid_t) arm,x86 int setuid:setuid(uid_t) arm64,mips,mips64,x86_64 int setreuid:setreuid32(uid_t, uid_t) arm,x86 int setreuid:setreuid(uid_t, uid_t) arm64,mips,mips64,x86_64 int setresuid:setresuid32(uid_t, uid_t, uid_t) arm,x86 int setresuid:setresuid(uid_t, uid_t, uid_t) arm64,mips,mips64,x86_64 int setresgid:setresgid32(gid_t, gid_t, gid_t) arm,x86 int setresgid:setresgid(gid_t, gid_t, gid_t) arm64,mips,mips64,x86_64 void* __brk:brk(void*) all int kill(pid_t, int) all int tgkill(pid_t tgid, pid_t tid, int sig) all int __ptrace:ptrace(int request, int pid, void* addr, void* data) all #
