|---|---|
| abi | common |
| entry point | sys_readlink |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for score) |
| man page | readlink(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r27 | 1035, the syscall number |
r4 | const char *path |
r5 | char *buf |
r6 | int bufsiz |
r4 | the return value |
Then run syscall to enter the kernel.
r7 is the error flag and r4 then holds the positive error number.
