semop on score
System V semaphore operations
sys_semop(int semid, struct sembuf *sops, unsigned nsops)| number | 193 (0xc1) |
|---|---|
| abi | common |
| kconfig | CONFIG_SYSVIPC |
| family | sysvipc see the whole family on score |
| entry point | sys_semop |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for score) |
| man page | semop(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r27 | 193, the syscall number |
r4 | int semid |
r5 | struct sembuf *sops |
r6 | unsigned nsops |
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.
