sendfile on score
transfer data between file descriptors
sys_sendfile(int out_fd, int in_fd, off_t *offset, size_t count)| number | 1046 (0x416) |
|---|---|
| abi | common |
| entry point | sys_sendfile |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for score) |
| man page | sendfile(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r27 | 1046, the syscall number |
r4 | int out_fd |
r5 | int in_fd |
r6 | off_t *offset |
r7 | size_t count |
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.
