crypto: Remove michael_mic from crypto_shash API

2026-04-08T08:11:37+00:00

Remove the "michael_mic" crypto_shash algorithm, since it's no longer
used.  Its only users were wireless drivers, which have now been
converted to use the michael_mic() function instead.

It makes sense that no other users ever appeared: Michael MIC is an
insecure algorithm that is specific to WPA TKIP, which itself was an
interim security solution to replace the broken WEP standard.

crypto: ansi_cprng - Remove unused ansi_cprng algorithm

2025-11-22T02:04:50+00:00

Remove ansi_cprng, since it's obsolete and unused, as confirmed at
https://lore.kernel.org/r/aQxpnckYMgAAOLpZ@gondor.apana.org.au/

This was originally added in 2008, apparently as a FIPS approved random
number generator.  Whether this has ever belonged upstream is
questionable.  Either way, ansi_cprng is no longer usable for this
purpose, since it's been superseded by the more modern algorithms in
crypto/drbg.c, and FIPS itself no longer allows it.  (NIST SP 800-131A
Rev 1 (2015) says that RNGs based on ANSI X9.31 will be disallowed after
2015.  NIST SP 800-131A Rev 2 (2019) confirms they are now disallowed.)

Therefore, there is no reason to keep it around.

Remove long-stale ext3 defconfig option

2025-10-15T14:57:28+00:00

Inspired by commit c065b6046b34 ("Use CONFIG_EXT4_FS instead of
CONFIG_EXT3_FS in all of the defconfigs") I looked around for any other
left-over EXT3 config options, and found some old defconfig files still
mentioned CONFIG_EXT3_DEFAULTS_TO_ORDERED.

That config option was removed a decade ago in commit c290ea01abb7 ("fs:
Remove ext3 filesystem driver").  It had a good run, but let's remove it
for good.

Use CONFIG_EXT4_FS instead of CONFIG_EXT3_FS in all of the defconfigs

2025-10-14T01:50:40+00:00

Commit d6ace46c82fd ("ext4: remove obsolete EXT3 config options")
removed the obsolete EXT3_CONFIG options, since it had been over a
decade since fs/ext3 had been removed.  Unfortunately, there were a
number of defconfigs that still used CONFIG_EXT3_FS which the cleanup
commit didn't fix up.  This led to a large number of defconfig test
builds to fail.  Oops.

crypto: tcrypt - rename CRYPTO_TEST to CRYPTO_BENCHMARK

2025-05-12T05:32:53+00:00

tcrypt is actually a benchmarking module and not the actual tests.  This
regularly causes confusion.  Update the kconfig option name and help
text accordingly.

lib/crc: remove unnecessary prompt for CONFIG_CRC16

2025-04-04T18:31:42+00:00

All modules that need CONFIG_CRC16 already select it, so there is no

arch//configs/defconfig: Replace AUTOFS4_FS by AUTOFS_FS

2023-07-29T21:08:22+00:00

Commit a2225d931f75 ("autofs: remove left-over autofs4 stubs")
promised the removal of the fs/autofs/Kconfig fragment for AUTOFS4_FS
within a couple of releases, but five years later this still has not
happened yet, and AUTOFS4_FS is still enabled in 63 defconfigs.

Get rid of it mechanically:

   git grep -l CONFIG_AUTOFS4_FS -- '*defconfig' |
       xargs sed -i 's/AUTOFS4_FS/AUTOFS_FS/'

Also just remove the AUTOFS4_FS config option stub.  Anybody who hasn't
regenerated their config file in the last five years will need to just
get the new name right when they do.

mm/slab: rename CONFIG_SLAB to CONFIG_SLAB_DEPRECATED

2023-05-26T17:01:47+00:00

As discussed at LSF/MM [1] [2] and with no objections raised there,
deprecate the SLAB allocator. Rename the user-visible option so that
users with CONFIG_SLAB=y get a new prompt with explanation during make
oldconfig, while make olddefconfig will just switch to SLUB.

In all defconfigs with CONFIG_SLAB=y remove the line so those also
switch to SLUB. Regressions due to the switch should be reported to
linux-mm and slab maintainers.
