- Subject: [PATCH] [Hurd] Fix __file_name_lookup_at() return value
This is my first patch to glibc, and I don't have any copyright assignment to
the FSF yet, but since the patch is a one liner I hope there is no problem with
Since I plan to submit more patches, I guess I should assign copyright to the
FSF. Can somebody please point me on how to do it?
The patch fixes a return value in __file_name_lookup_at(), which is supposed to
return file_t and was returning -1 instead of MACH_PORT_NULL. It can be easily
tested with `ln' from coreutils >= 8.4 (which uses linkat()), a simple `ln a b'
will fail with `Computer bought the farm'. This patch makes it fail with
`Invalid argument' (linkat() and __file_name_lookup_at() need more fixing, I'll
submit another patch for that later on).
