Modified files:
sys/kern vfs_aio.c
Log:
Do a bit more work in the aio code to simulate the credential environment
of the original AIO request: save and restore the active thread credential
as well as using the file credential, since MAC (and some other bits of
the system) rely on the thread credential instead of/as well as the
file credential. In brief: cache td->td_ucred when the AIO operation
is queued, temporarily set and restore the kernel thread credential,
and release the credential when done. Similar to ktrace credential
management.
