prctl on score
operations on a process or thread
sys_prctl(int option, unsigned long arg2, unsigned long arg3, unsigned long arg4, unsigned long arg5)| number | 167 (0xa7) |
|---|---|
| abi | common |
| entry point | sys_prctl |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for score) |
| man page | prctl(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r27 | 167, the syscall number |
r4 | int option |
r5 | unsigned long arg2 |
r6 | unsigned long arg3 |
r7 | unsigned long arg4 |
r8 | unsigned long arg5 |
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.
