kcmp
compare two processes to determine if they share a kernel resource
sys_kcmp(pid_t pid1, pid_t pid2, int type, unsigned long idx1, unsigned long idx2)| number | 272 (0x110) |
|---|---|
| abi | common |
| entry point | sys_kcmp |
| since | Linux 3.7 |
| man page | kcmp(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r6 | 272, the syscall number |
r0 | pid_t pid1 |
r1 | pid_t pid2 |
r2 | int type |
r3 | unsigned long idx1 |
r4 | unsigned long idx2 |
r0 | the return value |
Then run trap0(#1) to enter the kernel.
