5a0fcb0e - cxl: Remove driver

Wed, 19 Feb 2025 07:00:06 +0000

cxl: Remove driverRemove the cxl driver that provides support for the IBM CoherentAccelerator Processor Interface. Revert or clean up associated code inarch/powerpc that is no longer necessary.cxl has received minimal maintenance for several years, and is notsupported on the Power10 processor. We aren't aware of any users who arelikely to be using recent kernels.Thanks to Mikey Neuling, Ian Munsie, Daniel Axtens, Frederic Barrat,Christophe Lombard, Philippe Bergheaud, Vaibhav Jain and AlastairD'Silva for their work on this driver over the years.Signed-off-by: Andrew Donnellan Acked-by: Frederic Barrat Acked-by: Madhavan Srinivasan Signed-off-by: Michael Ellerman Link: https://patch.msgid.link/20250219070007.177725-2-ajd@linux.ibm.com List of files: /linux-6.15/arch/powerpc/configs/skiroot_defconfig

cdebfd27 - powerpc/config: Disable SLAB_DEBUG_ON in skiroot

Wed, 05 Jul 2023 02:30:56 +0000

powerpc/config: Disable SLAB_DEBUG_ON in skirootIn 5.10 commit 5e84dd547bce ("powerpc/configs/skiroot: Enable some morehardening options") set SLUB_DEBUG_ON.When 5.14 came around, commit 792702911f58 ("slub: force onno_hash_pointers when slub_debug is enabled") print all thepointers when SLUB_DEBUG_ON is set. This was fine, but in 5.12 commit5ead723a20e0 ("lib/vsprintf: no_hash_pointers prints all addresses asunhashed") added the warning at boot.Disable SLAB_DEBUG_ON as we don't want the nasty warning. We haveCONFIG_EXPERT so SLAB_DEBUG is enabled. We do lose the settings inDEBUG_DEFAULT_FLAGS, but it's not clear that these should have beenalways-on anyway.Signed-off-by: Joel Stanley Signed-off-by: Michael Ellerman Link: https://msgid.link/20230705023056.16273-1-joel@jms.id.au List of files: /linux-6.15/arch/powerpc/configs/skiroot_defconfig

Fri, 05 Nov 2021 20:45:18 +0000

mm: remove HARDENED_USERCOPY_FALLBACKThis has served its purpose and is no longer used. All usercopyviolations appear to have been handled by now, any remaining instances(or new bugs) will cause copies to be rejected.This isn't a direct revert of commit 2d891fbc3bb6 ("usercopy: Allowstrict enforcement of whitelists"); since usercopy_fallback iseffectively 0, the fallback handling is removed too.This also removes the usercopy_fallback module parameter on slab_common.Link: https://github.com/KSPP/linux/issues/153Link: https://lkml.kernel.org/r/20210921061149.1091163-1-steve@sk2.orgSigned-off-by: Stephen Kitt Suggested-by: Kees Cook Acked-by: Kees Cook Reviewed-by: Joel Stanley [defconfig change]Acked-by: David Rientjes Cc: Christoph Lameter Cc: Pekka Enberg Cc: Joonsoo Kim Cc: Vlastimil Babka Cc: James Morris Cc: "Serge E .

Sun, 23 Feb 2020 19:11:44 +0000

scsi: sr: remove references to BLK_DEV_SR_VENDOR, leave it enabledThis kernel configuration is basically enabling/disabling sr driver quirksdetection. While these quirks are for fairly rare devices (very old CDburners, and a glucometer), the additional detection of these models is avery minimal amount of code.The logic behind the quirks is always built into the sr driver.This also removes the config from all the defconfig files that are enablingthis already.Link: https://lore.kernel.org/r/20200223191144.726-1-flameeyes@flameeyes.comReviewed-by: Jens Axboe Signed-off-by: Diego Elio Pettenò Signed-off-by: Martin K.

5e84dd54 - powerpc/configs/skiroot: Enable some more hardening options

Tue, 21 Jan 2020 04:29:59 +0000

powerpc/configs/skiroot: Enable some more hardening optionsEnable more hardening options.Note BUG_ON_DATA_CORRUPTION selects DEBUG_LIST and is essentially justa synonym for it.DEBUG_SG, DEBUG_NOTIFIERS, DEBUG_LIST, DEBUG_CREDENTIALS andSCHED_STACK_END_CHECK should all be low overhead and just add a fewextra checks.SLAB_FREELIST_RANDOM, and SLUB_DEBUG_ON will add some overhead to theSLAB allocator, but nothing that should be meaningful for skiroot.Unselecting SLAB_MERGE_DEFAULT causes the SLAB to use more memory, butthe skiroot kernel shouldn't be memory constrained on any of oursystems, all it does is run a small bootloader.Disabling merging has some security/robustness benefit as it means auser-after-free or overflow will be limited to the objects in thatslab, rather than potentially affecting objects from unrelated slabsthat have been merged.Note also that slab merging is disabled anyway by enablingSLUB_DEBUG_ON, because of the SLAB_NEVER_MERGE mask.Signed-off-by: Michael Ellerman Acked-by: Joel Stanley Link: https://lore.kernel.org/r/20200121043000.16212-9-mpe@ellerman.id.au List of files: /linux-6.15/arch/powerpc/configs/skiroot_defconfig

Instead it's more helpful to reboot and bring theboot loader back up, and if the crash was transient we can then bootsuccessfully.Similarly if we panic we should reboot, with a short timeout in casesomeone is watching the console.Signed-off-by: Michael Ellerman Acked-by: Joel Stanley Link: https://lore.kernel.org/r/20200121043000.16212-8-mpe@ellerman.id.au List of files: /linux-6.15/arch/powerpc/configs/skiroot_defconfig
