Created attachment 268451 [details] Patch to fix off-by-one error for lookup of map keys exactly 255 characters long.
The RHTS test for bz195679 has uncovered a bug in autofs version 5 for lookups of keys that are exactly the maximum length allowed. This length is 255 and is defined in kernel include files and is used in the definition of the autofs kernel request packet. The test, bz195679, itself creates a test map with a key greater than 255 characters and so needs to be corrected to create a key of exactly 255 characters to test for this bug. Since bug 195679 concerns map entries (key plus mount target) greater than 255 characters the test will continue to verify the original issue.
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.
