fddcca51 - mtd: avoid stack overflow in MTD CFI code

Mon, 29 Feb 2016 12:20:28 +0000

mtd: avoid stack overflow in MTD CFI codeWhen map_word gets too large, we use a lot of kernel stack, and forMTD_MAP_BANK_WIDTH_32, this means we use more than the recommended1024 bytes in a number of functions:drivers/mtd/chips/cfi_cmdset_0020.c: In function 'cfi_staa_write_buffers':drivers/mtd/chips/cfi_cmdset_0020.c:651:1: warning: the frame size of 1336 bytes is larger than 1024 bytes [-Wframe-larger-than=]drivers/mtd/chips/cfi_cmdset_0020.c: In function 'cfi_staa_erase_varsize':drivers/mtd/chips/cfi_cmdset_0020.c:972:1: warning: the frame size of 1208 bytes is larger than 1024 bytes [-Wframe-larger-than=]drivers/mtd/chips/cfi_cmdset_0001.c: In function 'do_write_buffer':drivers/mtd/chips/cfi_cmdset_0001.c:1835:1: warning: the frame size of 1240 bytes is larger than 1024 bytes [-Wframe-larger-than=]This can be avoided if all operations on the map word are doneindirectly and the stack gets reused between the calls. We canmostly achieve this by selecting MTD_COMPLEX_MAPPINGS wheneverMTD_MAP_BANK_WIDTH_32 is set, but for the case that no otherbank width is enabled, we also need to use a non-constantmap_bankwidth() to convince the compiler to use less stack.Signed-off-by: Arnd Bergmann [Brian: this patch mostly achieves its goal by forcing MTD_COMPLEX_MAPPINGS (and the accompanying indirection) for 256-bit mappings; the rest of the change is mostly a wash, though it helps reduce stack size slightly. If we really care about supporting 256-bit mappings though, we should consider rewriting some of this code to avoid keeping and assigning so many 256-bit objects on the stack.]Signed-off-by: Brian Norris List of files: /linux-6.15/drivers/mtd/chips/Kconfig

f5f92b36 - mtd: cfi: enforce valid geometry configuration

Mon, 23 Nov 2015 13:39:33 +0000

mtd: cfi: enforce valid geometry configurationMTD allows compile-time configuration of the possible CFI geometrysettings that are allowed by the kernel, but that includes a couple ofinvalid configurations, where no bank width or no interleave settingis allowed. These are then caught with a compile-time warning:include/linux/mtd/cfi.h:76:2: warning: #warning No CONFIG_MTD_CFI_Ix selected. No NOR chip support can work.include/linux/mtd/map.h:145:2: warning: #warning "No CONFIG_MTD_MAP_BANK_WIDTH_xx selected. No NOR chip support can work"This is a bit annoying for randconfig tests, and can be avoided ifwe change the Kconfig logic to always select the simplest configurationwhen no other one is enabled.Signed-off-by: Arnd Bergmann Signed-off-by: Brian Norris List of files: /linux-6.15/drivers/mtd/chips/Kconfig

660685d9 - mtd: merge mtdchar module with mtdcore

Thu, 14 Mar 2013 11:27:40 +0000

mtd: merge mtdchar module with mtdcoreThe MTD subsystem has historically tried to be as configurable as possible. Theside-effect of this is that its configuration menu is rather large, and we aregradually shrinking it. For example, we recently merged partitions support withthe mtdcore.This patch does the next step - it merges the mtdchar module to mtdcore. And inthis case this is not only about eliminating too fine-grained separation andsimplifying the configuration menu. This is also about eliminating seeminglyuseless kernel module.Indeed, mtdchar is a module that allows user-space making use of MTD devicesvia /dev/mtd* character devices. If users do not enable it, they simply cannotuse MTD devices at all. They cannot read or write the flash contents. Is it asane and useful setup? I believe not. And everyone just enables mtdchar.Having mtdchar separate is also a little bit harmful. People sometimes miss thefact that they need to enable an additional configuration option to haveuser-space MTD interfaces, and then they wonder why on earth the kernel doesnot allow using the flash? They spend time asking around.Thus, let's just get rid of this module and make it part of mtd core.Note, mtdchar had additional configuration option to enable OTP interfaces,which are present on some flashes. I removed that option as well - it saves areally tiny amount space.[dwmw2: Strictly speaking, you can mount file systems on MTD devices just fine without the mtdchar (or mtdblock) devices; you just can't do other manipulations directly on the underlying device. But still I agree that it makes sense to make this unconditional. And Yay! we get to kill off an instance of checking CONFIG_foo_MODULE, which is an abomination that should never happen.]Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse List of files: /linux-6.15/drivers/mtd/chips/Kconfig

mtd: chips: reorganize Kconfig help on swappingThe Kconfig help on "Flash cmd/query data swapping" still mentionsLART_ENDIAN_BYTE. That option used to be relevant for settingCONFIG_MTD_CFI_LART_BIT_SWAP. That option and macro got both removed inv2.4.11-pre4. So, although LART endianness sounds intriguing, that partof the help text can be removed.And, while we're touching this choice, move the help text up one level.Currently it's available under the "NO" option, while it's relevant forall three options.Signed-off-by: Paul Bolle Signed-off-by: Artem Bityutskiy Signed-off-by: David Woodhouse List of files: /linux-6.15/drivers/mtd/chips/Kconfig
