Additional Information

Version of s3fs being used (`s3fs --version`)

Version of fuse being used (`pkg-config --modversion fuse`, `rpm -qi fuse` or `dpkg -s fuse`)

2.9.9

Kernel information (`uname -r`)

GNU/Linux Distribution, if applicable (`cat /etc/os-release`)

RHEL9.2

How to run s3fs, if applicable

Running via /etc/fstab

s3fs# /mnt/ _netdev,defaults,allow_other,umask=007,uid=0,mp_umask=0007,gid=1000,use_path_request_style,passwd_file=/etc/s3fs,url=https://plos3.westernpower.co.uk/,noexec 0 0

Details about issue

We are able to mount our S3 buckets successfully which is fine. My query is that, no matter what umask is set, whenever a new file is created, it applies executables permissions which we do not want. We would like the permissions to be rw only as although we can limit permissions access to these files that are accessible through the mount , if the file is a bash script for example, we don't want people running them (at least not by default).

E.g.

ls -l  /mnt/<bucketdir>/
-rwxrwx---. 1 root mygroup  8 Oct  5 09:44 example-pems
