scsi: aacraid: Remove useless code

2025-05-28T02:03:29+00:00

There isn't a AAC_MIN_NATIVE_SIZE defined so remove eight useless lines.
When at it remove also an unused #define

No functional change.

scsi: usb: Rename the RESERVE and RELEASE constants

2025-02-13T03:20:55+00:00

The names RESERVE and RELEASE are not only used in  but
also elsewhere in the kernel:

$ git grep -nHE 'define[[:blank:]]*(RESERVE|RELEASE)[[:blank:]]'
drivers/input/joystick/walkera0701.c:13:#define RESERVE 20000
drivers/s390/char/tape_std.h:56:#define RELEASE			0xD4	/* 3420 NOP, 3480 REJECT */
drivers/s390/char/tape_std.h:58:#define RESERVE			0xF4	/* 3420 NOP, 3480 REJECT */

Additionally, while the names of the symbolic constants RESERVE_10 and
RELEASE_10 include the command length, the command length is not included
in the RESERVE and RELEASE names. Address both issues by renaming the
RESERVE and RELEASE constants into RESERVE_6 and RELEASE_6 respectively.

scsi: Constify struct pci_error_handlers

2025-02-03T22:35:58+00:00

'struct pci_error_handlers' are not modified in these drivers.

Constifying these structures moves some data to a read-only section, so
increase overall security, especially when the structure holds some
function pointers.

On a x86_64, with allmodconfig, as an example:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  39049	   6429	    112	  45590	   b216	drivers/scsi/aacraid/linit.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  39113	   6365	    112	  45590	   b216	drivers/scsi/aacraid/linit.o

scsi: Convert SCSI drivers to .sdev_configure()

2024-12-04T20:34:28+00:00

The only difference between the .sdev_configure() and .slave_configure()
methods is that the former accepts an additional 'limits' argument.
Convert all SCSI drivers that define a .slave_configure() method to
.sdev_configure(). This patch prepares for removing the
.slave_configure() method. No functionality has been changed.

move asm/unaligned.h to linux/unaligned.h

asm/unaligned.h is always an include of asm-generic/unaligned.h;
might as well move that thing to linux/unaligned.h and include
that - there's nothing arch-specific in that header.

scsi: aacraid: Fix double-free on probe failure

2024-08-23T01:04:12+00:00

aac_probe_one() calls hardware-specific init functions through the
aac_driver_ident::init pointer, all of which eventually call down to
aac_init_adapter().

If aac_init_adapter() fails after allocating memory for aac_dev::queues,
it frees the memory but does not clear that member.

After the hardware-specific init function returns an error,
aac_probe_one() goes down an error path that frees the memory pointed to
by aac_dev::queues, resulting.in a double-free.

Merge patch series "scsi: aacraid: struct sgmap: Replace 1-element arrays with flexible arrays"

2024-08-03T01:39:30+00:00

Kees Cook  says:

This replaces some of the last remaining uses in the kernel of
1-element "fake" flexible arrays with modern C99 flexible arrays. Some
refactoring is done to ease this, and binary differences are
identified. For the on stack size changes in patch 2, the "yes, that
is the source of the binary differences" debugging patch can be found
here[1].
