mmap on score
map or unmap files or devices into memory
sys_mmap(unsigned long addr, unsigned long len, unsigned long prot, unsigned long flags, unsigned long fd, off_t pgoff)| number | 1058 (0x422) |
|---|---|
| abi | common |
| entry point | sys_mmap |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for score) |
| man page | mmap(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r27 | 1058, the syscall number |
r4 | unsigned long addr |
r5 | unsigned long len |
r6 | unsigned long prot |
r7 | unsigned long flags |
r8 | unsigned long fd |
r9 | off_t pgoff |
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.
