Hi,
We received a bugzilla report
https://bugzilla.redhat.com/show_bug.cgi?id=1310682
of partitions being automounted unexpectedly. Testing showed that
8a3e33cf92c7 ("ata: ahci: find eSATA ports and flag them as removable") was
responsible.
This seems to be classified as 'breaking' userspace given that this behavior
results
in partitions that were previously unmounted now being being mounted
unwanted
automatically which is unwanted behavior for the user. Can we revert this
patch or
give a fix to change this behavior?
Do the affected users have sata ports set to hotplug capable? Because that's
what the patch does: it flags ports which have the hotplug capability enabled
as "removable", and I guess redhat just automounts anything that is flagged
as a removable disk (like an usb drive).
Manuel
The mounting comes from udisks. udisks will automount anything marked as removable
unless explicitly forbidden. You can argue whether or not this is good design but
it's still a change in behavior from what udisks was relying on to decide
whether or not to automount. lspci from the users hardware:
00:1f.2 SATA controller: Intel Corporation C600/X79 series chipset 6-Port SATA
AHCI Controller (rev 06)
I'll make a build with the patch you gave for testing.
Thanks,
Laura
