Description of problem: I can plugin a usb memory stick into a client, can open a nautilus window on the mount, and can see icons for the folders and files on the mount, can open folders, but attempting to read any file with any application results in an error. The problem is always a failure to allocate memory during read() Version-Release number of selected component (if applicable): ltspfs-0.5.8-1.fc10.x86_64 How reproducible: 100% Steps to Reproduce: 1. strace cat /media/ellson/FEDORA/syslinux/boot.cat 2. 3.

Expected results: ability to open files on usb memory sticks Additional info:
This is extremely bizarre. Ryan, any ideas?
We still have this problem on the school system. On my home sytstem, USB memory sticks work just fine. I've reloaded the ltsp-client software on both systems to be sure they are identical. I've checked everything I can think of on the servers, but can't find any differences. The symptoms are: - Plugin a USB stick and it shows on the desktop, but attempting to read or write a file to it results in a gui popup: Error reading from file: cannot allocate memory - The mount point is weird, even root can't access it: root@sol:~# cd /media/test3 root@sol:test3# ls -l ls: cannot access CANON_DC: Permission denied total 0 d????????? ? ? ? ? ? CANON_DC - Mount on the server shows: gvfs-fuse-daemon on /home/test3/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=test3) ltspfs on /media/test3/CANON_DC type fuse.ltspfs (rw,nosuid,nodev,user=test3) Any ideas? What should I investigate for permissions problems on gvfs mounts?
I cannot prioritize looking at this. did you ask upstream? they wrote and understand this part of the code.
Tried completely fresh install of fedora-11 and still the same problem, but finally some new information. This bug affects x86_64 ltsp clients only! i386 clients work fine. Mounting the memory stick works, but trying to read or write to it fails with: ellson@bock:usbdisk-sda1> cat foo cat: foo: Cannot allocate memory I suspect this code in ltspfsd (also the similar malloc in ltspfs_write() ) void ltspfs_read(int sockfd, XDR * in) { XDR out; char path[PATH_MAX]; char output[LTSP_MAXBUF]; int i; int fd; int result; size_t size; off_t offset; char *buf; if (!xdr_u_int(in, &size)) { /* Get the size */ eacces(sockfd); return; } if (!xdr_longlong_t(in, &offset)) { /* Get the offset */ eacces(sockfd); return; } if (get_fn(sockfd, in, path)) { /* Get the path */ eacces(sockfd); return; } buf = malloc(size); /* * Check result of malloc */ if (!buf) { status_return(sockfd, FAIL); return; } Partularly since this code is generating these build warnings!

The ltsp.spec lists https://code.launchpad.net/ltspfs, but try to report a bug there and you get: LtspFS (Unspecified) does not use Launchpad as its bug tracker. The Launchpad pages list Scott Balneaves as the maintainer, so I'll try adding him to needinfo.
I think I found the right place to report it: https://bugs.launchpad.net/ltsp/+bug/415952
This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. 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 WONTFIX if it remains open with a Fedora 'version' of '10'. 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 prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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.

This problem still exists in Fedora 11.

Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 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. Thank you for reporting this bug and we are sorry it could not be fixed.
