I think you need to install 'fuse' (and 'fuse-libs', but you've got that already). I'm strongly suspecting this is a kernel problem, since I'm NOT running the Fedora kernel, but an upstream kernel. I ran the program with debugging enabled: $ ./hello -f -d /tmp/mnt FUSE library version: 2.9.3 nullpath_ok: 0 nopath: 0 utime_omit_ok: 0 unique: 1, opcode: INIT (26), nodeid: 0, insize: 56, pid: 0 INIT: 7.22 flags=0x0000f7fb max_readahead=0x00020000 INIT: 7.19 flags=0x00000011 max_readahead=0x00020000 max_write=0x00020000 max_background=0 congestion_threshold=0 unique: 1, success, outsize: 40 <--- no further output here until I run fusermount -u: unique: 2, opcode: FORGET (2), nodeid: 1, insize: 48, pid: 0 FORGET 1/1 By way of comparison, on x86 there is a lot more output seen, and I see output every time something accesses the fuse mount. So ... kernel may be broken or not sending packets or something. Ignore my previous comment; turns out installing fuse-devel does not pull in the fuse package.

I've updated the summary to reflect that this is only a problem with the sunxi kernel. This message is a reminder that Fedora 20 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 20. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '20'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 20 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
Created attachment 835743 [details] hello.c Description of problem: Take the hello world example from the FUSE sources (hello.c, attached) and compile it on ARM: $ gcc -D_FILE_OFFSET_BITS=64 hello.c -o hello -lfuse $ mkdir /tmp/mnt $ ./hello /tmp/mnt There is no error, but the mount point does not work at all: $ ls -l ls: cannot access mnt: Permission denied [...] d?????????? ? ? ? ? ? mnt $ ls /tmp/mnt ls: cannot access /tmp/mnt: Permission denied Version-Release number of selected component (if applicable): fuse-2.9.3-2.fc20.armv7hl How reproducible: 100% Steps to Reproduce: 1. See above. Additional info: I ran gdb on the process, and the kernel just never writes anything to the FUSE socket. The hello.c file attached is from examples/hello.c in the FUSE 2.9.3 tarball.
