fcntl64 on score
manipulate file descriptor
sys_fcntl64(unsigned int fd, unsigned int cmd, unsigned long arg)| number | 25 (0x19) |
|---|---|
| abi | common |
| entry point | sys_fcntl64 |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for score) |
| man page | fcntl64(2) |

Registers
| register | value |
|---|---|
r27 | 25, the syscall number |
r4 | unsigned int fd |
r5 | unsigned int cmd |
r6 | unsigned long arg |
r4 | the return value |
Then run syscall to enter the kernel.
r7 is the error flag and r4 then holds the positive error number.
This architecture was removed from the Linux kernel in Linux 4.17. The newest release with a syscall table here is Linux 4.16. The other removed architectures live on the historical architectures page.
