            Bug ID: 3954
           Summary: scp -t . has FORTIFY: umask: called with invalid mask
                    7077 Aborted on Android
           Product: Portable OpenSSH
           Version: 10.3p1
          Hardware: ARM64
                OS: Other
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: scp
          Assignee: unassigned-bugs at mindrot.org
          Reporter: rkirkman at termux.dev

In OpenSSH version 10.3p1, there is a commit
https://github.com/openssh/openssh-portable/commit/487e8ac146f7d6616f65c125d5edb210519b833a
, which adds the use of mask |= 07000 before umask(mask) in the code of
the scp command.

Unfortunately, doing that results in this error if the scp -t . command
is used in an OpenSSH build compiled for and running on Android,
because Android's C standard library does not allow programs to perform
that operation.

```
FORTIFY: umask: called with invalid mask 7077
Aborted                    scp -t .
```
