Subject: [PATCH] RHEL-8: aarch64: fixes statsnoop and opensnoop
|
|
|
b7cc67 |
|
|
|
b7cc67 |
On aarch64 the open syscall has been dropped. Only openat remains,
|
|
|
b7cc67 |
wich is called by libc open() function.
|
|
|
b7cc67 |
|
|
|
b7cc67 |
The state of *stat* syscalls, is a mess. They are several generations
|
|
|
b7cc67 |
of the system calls, and not all arches provides all of them. For
|
|
|
b7cc67 |
instance, new(l)stat are missing from aarch64.
|
|
|
b7cc67 |
|
|
|
b7cc67 |
The only way I can think of fixing thess is RHEL-8 only arch specific
|
|
|
b7cc67 |
patches.
