Patch to check for root-less multi-mount map entry
Not sure this patch will work in all cases so a little
more testing would be in order.
I seem to remember you weren't entirely happy with
check_is_multi() when it went into version 4.1.4 so please
check that it is OK.
Wow, I didn't even know that was legal! I'll take a look, thanks! (In reply to comment #3) > Wow, I didn't even know that was legal! I'll take a look, thanks! Yeah, there's a few instances of it in the connectathon test suite. (In reply to comment #2) > Created an attachment (id=309905) [edit] > Patch to check for root-less multi-mount map entry Wow, I went ahead and created almost exactly the same patch. I really need to read more closely! > Not sure this patch will work in all cases so a little > more testing would be in order. I'll run it through rhts. > I seem to remember you weren't entirely happy with > check_is_multi() when it went into version 4.1.4 so please > check that it is OK. OK, I'll double check that. Thanks!

It seems to work for all of the cases that I could come up with. This seems worth fixing to me. If it's approved, I'll write an rhts test case for it. This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. This fix is available in autofs versions 4.1.3-235.5 and later. An RHTS test has been added under /CoreOS/autofs/bugzillas, subtest bz452202. Release note added. If any revisions are required, please set the "requires_release_notes" flag to "?" and edit the "Release Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team.

Description of problem: When testing some recent kernel patches on RHEL 4 I noticed that autofs v4 isn't parsing rootless multi-mounts map entries quite right. Version-Release number of selected component (if applicable): autofs-4.1.3-231 How reproducible: Always. Steps to Reproduce: 1. Add "/test /etc/auto.multi" to the master map. 2. Use the following map, /etc/auto.multi: foo :/export/1 \ /2 :/export/2 \ /3 :/export/3 3. Perform "ls /test/foo/2" Actual results: Multi-map entry fails to mount. Expected results: Multi-map entry mounts correctly. Additional info: At first I thought there was an issue with the ":" escape handling but once I corrected the multi-map parsing the colon escaped locations were handled OK.
