1# This file is used to automatically generate bionic's system call stubs. 2# 3# Each non-blank, non-comment line has the following format: 4# 5# return_type func_name[|alias_list][:syscall_name[:socketcall_id]]([parameter_list]) arch_list 6# 7# where: 8# arch_list ::= "all" | arches 9# arches ::= arch | arch "," arches 10# arch ::= "arm" | "arm64" | "x86" | "x86_64" | "lp32" | "lp64" 11# 12# Note: 13# - syscall_name corresponds to the name of the syscall, which may differ from 14# the exported function name (example: the exit syscall is implemented by the _exit() 15# function, which is not the same as the standard C exit() function which calls it) 16# 17# - alias_list is optional comma separated list of function aliases. 18# 19# - The call_id parameter, given that func_name and syscall_name have 20# been provided, allows the user to specify dispatch style syscalls. 21# For example, socket() syscall on i386 actually becomes: 22# socketcall(__NR_socket, 1, *(rest of args on stack)). 23# 24# - Each parameter type is assumed to be stored in 32 bits. 25# 26# This file is processed by a python script named gensyscalls.py, run via 27# genrules in Android.bp. 28 29int execve(const char*, char* const*, char* const*) all 30 31uid_t getuid:getuid32() lp32 32uid_t getuid:getuid() lp64 33gid_t getgid:getgid32() lp32 34gid_t getgid:getgid() lp64 35uid_t geteuid:geteuid32() lp32 36uid_t geteuid:geteuid() lp64 37gid_t getegid:getegid32() lp32 38gid_t getegid:getegid() lp64 39uid_t getresuid:getresuid32(uid_t* ruid, uid_t* euid, uid_t* suid) lp32 40uid_t getresuid:getresuid(uid_t* ruid, uid_t* euid, uid_t* suid) lp64 41gid_t getresgid:getresgid32(gid_t* rgid, gid_t* egid, gid_t* sgid) lp32 42gid_t getresgid:getresgid(gid_t* rgid, gid_t* egid, gid_t* sgid) lp64 43ssize_t readahead(int, off64_t, size_t) all 44int getgroups:getgroups32(int, gid_t*) lp32 45int getgroups:getgroups(int, gid_t*) lp64 46pid_t getpgid(pid_t) all 47pid_t getppid() all 48pid_t getsid(pid_t) all 49pid_t setsid() all 50int setgid:setgid32(gid_t) lp32 51int setgid:setgid(gid_t) lp64 52int setuid:setuid32(uid_t) lp32 53int setuid:setuid(uid_t) lp64 54int setreuid:setreuid32(uid_t, uid_t) lp32 55int setreuid:setreuid(uid_t, uid_t) lp64 56int setresuid:setresuid32(uid_t, uid_t, uid_t) lp32 57int setresuid:setresuid(uid_t, uid_t, uid_t) lp64 58int setresgid:setresgid32(gid_t, gid_t, gid_t) lp32 59int setresgid:setresgid(gid_t, gid_t, gid_t) lp64 60void* __brk:brk(void*) all 61int kill(pid_t, int) all 62int tgkill(pid_t tgid, pid_t tid, int sig) all 63int __ptrace:ptrace(int request, int pid, void* addr, void* data) all 64 65# <sys/resource.h> 66int getrusage(int, struct rusage*) all 67int __getpriority:getpriority(int, id_t) all 68int setpriority(int, id_t, int) all 69# On LP64, rlimit and rlimit64 are the same. 70# On 32-bit systems we use prlimit64 to implement the rlimit64 functions. 71int getrlimit:ugetrlimit(int, struct rlimit*) lp32 72int getrlimit|getrlimit64(int, struct rlimit*) lp64 73int setrlimit(int, const struct rlimit*) lp32 74int setrlimit|setrlimit64(int, const struct rlimit*) lp64 75int prlimit64|prlimit(pid_t, int, struct rlimit64*, const struct rlimit64*) lp64 76int prlimit64(pid_t, int, struct rlimit64*, const struct rlimit64*) lp32 77 78int setgroups:setgroups32(int, const gid_t*) lp32 79int setgroups:setgroups(int, const gid_t*) lp64 80int setpgid(pid_t, pid_t) all 81int setregid:setregid32(gid_t, gid_t) lp32 82int setregid:setregid(gid_t, gid_t) lp64 83int chroot(const char*) all 84int prctl(int, unsigned long, unsigned long, unsigned long, unsigned long) all 85long __arch_prctl:arch_prctl(int, unsigned long) x86_64 86int capget(cap_user_header_t header, cap_user_data_t data) all 87int capset(cap_user_header_t header, const cap_user_data_t data) all 88int sigaltstack(const stack_t*, stack_t*) all 89int acct(const char* filepath) all 90 91# file descriptors 92ssize_t read(int, void*, size_t) all 93ssize_t write(int, const void*, size_t) all 94ssize_t pread64(int, void*, size_t, off64_t) lp32 95ssize_t pread64|pread(int, void*, size_t, off_t) lp64 96ssize_t pwrite64(int, void*, size_t, off64_t) lp32 97ssize_t pwrite64|pwrite(int, void*, size_t, off_t) lp64 98 99# On LP32, preadv/pwritev don't use off64_t --- they use pairs of 32-bit 100# arguments to avoid problems on architectures like arm32 where 64-bit arguments 101# must be in a register pair starting with an even-numbered register. 102# See linux/fs/read_write.c and https://lwn.net/Articles/311630/. 103# Note that there's an unused always-0 second long even on LP64!
