check_condition code-path was similar but more
complicated to Reset. It went like this:
1. extra space was allocated at aha152x_scdata for mirroring
scsi_cmnd members.
2. At aha152x_internal_queue() every not check_condition
(REQUEST_SENSE) command was copied to above members in
case of error.
3. At busfree_run() in the DONE_CS phase if a Status of
SAM_STAT_CHECK_CONDITION was detected. The command was
re-queued Internally using aha152x_internal_queue(,,check_condition,)
The old command members are over written with the
REQUEST_SENSE info.
4. At busfree_run() in the DONE_CS phase again. If it is a
check_condition command, info was restored from mirror
made at first call to aha152x_internal_queue() (see 2)
and the command is completed.
What I did is:
1. Allocate less space in aha152x_scdata only for the 16-byte
original command. (which is actually not needed by scsi-ml
anymore at this stage. But this is to much knowledge of scsi-ml)
2. If Status == SAM_STAT_CHECK_CONDITION, then like before
re-queue a REQUEST_SENSE command. But only now save original
command members. (Less of them)
3. In aha152x_internal_queue(), just like for Reset, use the
check_condition hint to set differently the working members.
execute the command.
4. At busfree_run() in the DONE_CS phase again. restore needed
members.
While at it. This patch fixes a BUG. Old code when sending
a REQUEST_SENSE for a failed command. Would than return with

[SCSI] aha152x: preliminary fixes and some comments
hunk by hunk:
- CHECK_CONDITION is what happens to cmnd->status >> 1
or after status_byte() macro. But here it is used
directly on status which means 0x1 which is an undefined
bit in the standard. And is a status that will never
return from a target.
- in busfree_run at the DONE_SC phase we have 3 distinct
operation:
1-if(DONE_SC->SCp.phase & check_condition)
The REQUEST_SENSE command return.
- Restore original command
- Than continue to operation 3.
2-if(DONE_SC->SCp.Status==SAM_STAT_CHECK_CONDITION)
A regular command returned with a status.
- Internally re-Q a REQUEST_SENSE.
- Do not do operation 3.
3-
- Complete the command and return it to scsi-ml
So the 0x2 in both these operations (1,2) means the scsi
check-condition status, hence SAM_STAT_CHECK_CONDITION
- Here the code asks about !(DONE_SC->SCp.Status & not_issued)
but "not_issued" is an enum belonging to the "phase" member
and not to the Status returned from target. The reason this
works is because not_issued==1 and Also CHECK_CONDITION==1
(remember from hunk 1). So actually the code was asking
!(DONE_SC->SCp.Status & CHECK_CONDITION). Which means
"Has the status been read from target yet?"
Staus is read at status_run(). "not_issued" is
cleared in seldo_run() which is usually earlier than
status_run().
So this patch does nothing as far as assembly is concerned
but it does let the reader understand what is going on.

Net/Security: fix memory leaks from security_secid_to_secctx()
The security_secid_to_secctx() function returns memory that must be freed
by a call to security_release_secctx() which was not always happening. This
patch fixes two of these problems (all that I could find in the kernel source
at present).

SELinux: restore proper NetLabel caching behavior
A small fix to the SELinux/NetLabel glue code to ensure that the NetLabel
cache is utilized when possible. This was broken when the SELinux/NetLabel
glue code was reorganized in the last kernel release.
