fallocate on score
manipulate file space
sys_fallocate(int fd, int mode, loff_t offset, loff_t len)| number | 47 (0x2f) |
|---|---|
| abi | common |
| entry point | sys_fallocate |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for score) |
| man page | fallocate(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r27 | 47, the syscall number |
r4 | int fd |
r5 | int mode |
r6 | loff_t offset |
r7 | loff_t len |
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.
