[Comment 1 Jory A. Pratt 2009-12-14 14:25:42 UTC]

Have you tested a vanilla-2.6.32? This is gonna be more a kernel specific issue on ia64 and not hardened.

[Comment 2 Dennis Schridde 2009-12-14 16:08:48 UTC]

No, I have not tested that.

[Comment 3 PaX Team 2009-12-31 15:13:04 UTC]

this will be fixed in the next PaX patch, for now you'll have to compile in fuse/cuse or add the following lines to the end of fs/fuse/dev.c:

EXPORT_SYMBOL_GPL(fuse_dev_read);
EXPORT_SYMBOL_GPL(fuse_dev_write);
EXPORT_SYMBOL_GPL(fuse_dev_poll);
EXPORT_SYMBOL_GPL(fuse_dev_fasync);

[Comment 4 Anthony Basile 2010-06-03 00:48:26 UTC]

I just tested this on the latest ebuild in the tree: hardened-source-2.6.32-r8 and it appears to be fixed on x86 and amd64.  The export symbol lines are in fs/fuse/dev.c and the FUSE and CUSE modules compile correctly.

The bug was hit on ia64 but was probably cross arch.  If the reporter wants to test it on his hardware and report back, we can close this bug as resolved fixed.

[Comment 5 Anthony Basile 2010-07-07 19:23:16 UTC]

One month and no answer from the reporter.  If there are no further issues, I'll close the bug as fixed in a day or so.

[Comment 6 Dennis Schridde 2010-07-07 20:35:11 UTC]

Seems to compile fine in -r10.
