Patch "reiserfs: avoid a -Wmaybe-uninitialized warning" has been added to the 4.4-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled reiserfs: avoid a -Wmaybe-uninitialized warning to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: reiserfs-avoid-a-wmaybe-uninitialized-warning.patch and it can be found in the queue-4.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From ab4949640d6674b617b314ad3c2c00353304bab9 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann <arnd(a)arndb.de> Date: Thu, 23 Mar 2017 16:06:13 +0100 Subject: reiserfs: avoid a -Wmaybe-uninitialized warning From: Arnd Bergmann <arnd(a)arndb.de> commit ab4949640d6674b617b314ad3c2c00353304bab9 upstream. The latest gcc-7.0.1 snapshot warns about an unintialized variable use: In file included from fs/reiserfs/lbalance.c:8:0: fs/reiserfs/lbalance.c: In function 'leaf_item_bottle.isra.3': fs/reiserfs/reiserfs.h:1279:13: error: '*((void *)&n_ih+8).v' may be used uninitialized in this function [-Werror=maybe-uninitialized] v2->v = (v2->v & cpu_to_le64(15ULL << 60)) | cpu_to_le64(offset); ~~^~~ fs/reiserfs/reiserfs.h:1279:13: error: '*((void *)&n_ih+8).v' may be used uninitialized in this function [-Werror=maybe-uninitialized] v2->v = (v2->v & cpu_to_le64(15ULL << 60)) | cpu_to_le64(offset); This happens because the offset/type pair that is stored in ih.key.u.k_offset_v2 is actually uninitialized when we call set_le_ih_k_offset() and set_le_ih_k_type(). After we have called both, all data is correct, but the first of the two reads uninitialized data for the type field and writes it back before it gets overwritten. This works around the warning by initializing the k_offset_v2 through the slightly larger memcpy().

A couple of functions and variables in the profile implementation are used only on SMP systems by the procfs code, but are unused if either procfs is disabled or in uniprocessor kernels. gcc prints a harmless warning about the unused symbols: kernel/profile.c:243:13: error: 'profile_flip_buffers' defined but not used [-Werror=unused-function] static void profile_flip_buffers(void) ^ kernel/profile.c:266:13: error: 'profile_discard_flip_buffers' defined but not used [-Werror=unused-function] static void profile_discard_flip_buffers(void) ^ kernel/profile.c:330:12: error: 'profile_cpu_callback' defined but not used [-Werror=unused-function] static int profile_cpu_callback(struct notifier_block *info, ^ This adds further #ifdef to the file, to annotate exactly in which cases they are used.

The proc_create() and remove_proc_entry() functions do not reference their arguments when CONFIG_PROC_FS is disabled, so we get a couple of warnings about unused variables in IPVS: ipvs/ip_vs_app.c:608:14: warning: unused variable 'net' [-Wunused-variable] ipvs/ip_vs_ctl.c:3950:14: warning: unused variable 'net' [-Wunused-variable] ipvs/ip_vs_ctl.c:3994:14: warning: unused variable 'net' [-Wunused-variable] This removes the local variables and instead looks them up separately for each use, which obviously avoids the warning.

Patch "net: hp100: remove unnecessary #ifdefs" has been added to the 4.4-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled net: hp100: remove unnecessary #ifdefs to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: net-hp100-remove-unnecessary-ifdefs.patch and it can be found in the queue-4.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 747a11279a442b913a57bf38934879babab3b58b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann <arnd(a)arndb.de> Date: Fri, 29 Jan 2016 12:39:11 +0100 Subject: net: hp100: remove unnecessary #ifdefs From: Arnd Bergmann <arnd(a)arndb.de> commit 747a11279a442b913a57bf38934879babab3b58b upstream. Building the hp100 ethernet driver causes warnings when both the PCI and EISA drivers are disabled: ethernet/hp/hp100.c: In function 'hp100_module_init': ethernet/hp/hp100.c:3047:2: warning: label 'out3' defined but not used [-Wunused-label] ethernet/hp/hp100.c: At top level: ethernet/hp/hp100.c:2828:13: warning: 'cleanup_dev' defined but not used [-Wunused-function] We can easily avoid the warnings and make the driver look slightly nicer by removing the #ifdefs that check for the CONFIG_PCI and CONFIG_EISA, as all the registration functions are designed to have no effect when the buses are disabled.

Patch "mtd: sh_flctl: pass FIFO as physical address" has been added to the 4.4-stable tree

This is a note to let you know that I've just added the patch titled mtd: sh_flctl: pass FIFO as physical address to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: mtd-sh_flctl-pass-fifo-as-physical-address.patch and it can be found in the queue-4.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 1873315fb156cbc8e46f28e8b128f17ff6c31728 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann <arnd(a)arndb.de> Date: Tue, 8 Dec 2015 16:38:12 +0100 Subject: mtd: sh_flctl: pass FIFO as physical address From: Arnd Bergmann <arnd(a)arndb.de> commit 1873315fb156cbc8e46f28e8b128f17ff6c31728 upstream. By convention, the FIFO address we pass using dmaengine_slave_config is a physical address in the form that is understood by the DMA engine, as a dma_addr_t, phys_addr_t or resource_size_t. The sh_flctl driver however passes a virtual __iomem address that gets cast to dma_addr_t in the slave driver. This happens to work on shmobile because that platform sets up an identity mapping for its MMIO regions, but such code is not portable to other platforms, and prevents us from ever changing the platform mapping or reusing the driver on other architectures like ARM64 that might not have the mapping. We also get a warning about a type mismatch for the case that dma_addr_t is wider than a pointer, i.e. when CONFIG_LPAE is set: drivers/mtd/nand/sh_flctl.c: In function 'flctl_setup_dma': drivers/mtd/nand/sh_flctl.c:163:17: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast] cfg.dst_addr = (dma_addr_t)FLDTFIFO(flctl); This changes the driver to instead pass the physical address of the FIFO that is extracted from the MMIO resource, making the code more portable and avoiding the warning.

Patch "mtd: maps: add __init attribute" has been added to the 4.4-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled mtd: maps: add __init attribute to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: mtd-maps-add-__init-attribute.patch and it can be found in the queue-4.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From e4106a7c8236eb7b91686d36f3bf33ee43db94b4 Mon Sep 17 00:00:00 2001 From: Julia Lawall <julia.lawall(a)lip6.fr> Date: Tue, 19 Apr 2016 14:33:33 +0200 Subject: mtd: maps: add __init attribute From: Julia Lawall <julia.lawall(a)lip6.fr> commit e4106a7c8236eb7b91686d36f3bf33ee43db94b4 upstream. Add __init attribute on functions that are only called from other __init functions and that are not inlined, at least with gcc version 4.8.4 on an x86 machine with allyesconfig. Currently, the functions are put in the .text.unlikely segment. Declaring them as __init will cause them to be put in the .init.text and to disappear after initialization. The result of objdump -x on the functions before the change is as follows: 00000000000001bc l F .text.unlikely 00000000000006a2 ck804xrom_init_one.isra.1 00000000000001aa l F .text.unlikely 0000000000000764 esb2rom_init_one.isra.1 00000000000001db l F .text.unlikely 0000000000000716 ichxrom_init_one.isra.1 And after the change it is as follows: 0000000000000000 l F .init.text 000000000000069d ck804xrom_init_one.isra.1 0000000000000000 l F .init.text 000000000000075f esb2rom_init_one.isra.1 0000000000000000 l F .init.text 0000000000000711 ichxrom_init_one.isra.1 Done with the help of Coccinelle. The semantic patch checks for local static non-init functions that are called from an __init function and are not called from any other function. Note that in each case, the function is stored in the probe field of a pci_driver structure, but this code is under an #if 0. The #if 0s have been unchanged since 2009 at the latest.

MTD allows compile-time configuration of the possible CFI geometry settings that are allowed by the kernel, but that includes a couple of invalid configurations, where no bank width or no interleave setting is 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 if we change the Kconfig logic to always select the simplest configuration when no other one is enabled.

Patch "modsign: hide openssl output in silent builds" has been added to the 4.4-stable tree

If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 5d06ee20b662a78417245714fc576cba90e6374f Mon Sep 17 00:00:00 2001 From: Arnd Bergmann <arnd(a)arndb.de> Date: Thu, 25 Feb 2016 17:31:32 +0100 Subject: modsign: hide openssl output in silent builds From: Arnd Bergmann <arnd(a)arndb.de> commit 5d06ee20b662a78417245714fc576cba90e6374f upstream. When a user calls 'make -s', we can assume they don't want to see any output except for warnings and errors, but instead they see this for a warning free build: ### ### Now generating an X.509 key pair to be used for signing modules. ### ### If this takes a long time, you might wish to run rngd in the ### background to keep the supply of entropy topped up. It ### needs to be run as root, and uses a hardware random ### number generator if one is available. ### Generating a 4096 bit RSA private key .................................................................................................................................................................................................................................++ ..............................................................................................................................++ writing new private key to 'certs/signing_key.pem' ----- ### ### Key pair generated. ### The output can confuse simple build testing scripts that just check for an empty build log. This patch silences all the output: - "echo" is changed to "@$(kecho)", which is dropped when "-s" gets passed - the openssl command itself is only printed with V=1, using the $(Q) macro - The output of openssl gets redirected to /dev/null on "-s" builds.

Patch "md: avoid warning for 32-bit sector_t" has been added to the 4.4-stable tree

This is a note to let you know that I've just added the patch titled md: avoid warning for 32-bit sector_t to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: md-avoid-warning-for-32-bit-sector_t.patch and it can be found in the queue-4.4 subdirectory.

When CONFIG_LBDAF is not set, sector_t is only 32-bits wide, which means we cannot have devices with more than 2TB, and the code that is trying to handle compatibility support for large devices in md version 0.90 is meaningless but also causes a compile-time warning: drivers/md/md.c: In function 'super_90_load': drivers/md/md.c:1029:19: warning: large integer implicitly truncated to unsigned type [-Woverflow] drivers/md/md.c: In function 'super_90_rdev_size_change': drivers/md/md.c:1323:17: warning: large integer implicitly truncated to unsigned type [-Woverflow] This adds a check for CONFIG_LBDAF to avoid even getting into this code path, and also adds an explicit cast to let the compiler know it doesn't have to warn about the truncation.

This patch fixes it by clearing the queue for "Page not Present" if "Page Ready" occurs before the next vmentry since the GUP has already got the required page and shadow page table has already been fixed by "Page Ready" handler.

Patch "isdn: icn: remove a #warning" has been added to the 4.4-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled isdn: icn: remove a #warning to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: isdn-icn-remove-a-warning.patch and it can be found in the queue-4.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From 01ed1e1504ac83a8b0b365c9f55d3427babbd7d9 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann <arnd(a)arndb.de> Date: Wed, 2 Mar 2016 20:06:45 +0100 Subject: isdn: icn: remove a #warning From: Arnd Bergmann <arnd(a)arndb.de> commit 01ed1e1504ac83a8b0b365c9f55d3427babbd7d9 upstream. The icn driver currently produces an unconditional #warning whenever we build it, introduced by Karsten Keil back in 2003: #warning TODO test headroom or use skb->nb to flag ACK Karsten's original commit (from BitKeeper) contains this description: - here are lot of bugs left, so ISDN is not stable yet but I think it's really time to fix it, even if it need some cycles to get it right (normally I'm only send patches if it works 100% for me). - I add some additional #warnings to address places which need fixing (I hope that some of the other ISDN developer jump in) Apparently this has not happened, and it is unlikely that it ever will, given that the driver doesn't seem to work. No substantial bug fixes other than janitorial cleanups have happened in the driver since then, and I see no indication that anyone who patched it had the hardware. We should probably either remove the driver, or remove all of i4l, but for now, this shuts up the distracting #warning by turning it into a comment.

I noticed that this function uses a lot of kernel stack when the "latent entropy" plugin is enabled: drivers/isdn/hardware/eicon/message.c: In function 'sig_ind': drivers/isdn/hardware/eicon/message.c:6113:1: error: the frame size of 1168 bytes is larger than 1152 bytes [-Werror=frame-larger-than=] We currently don't warn about this, as we raise the warning limit to 2048 bytes in mainline, but I'd like to lower that limit again in the future, and this function can easily be changed to be more efficient and avoid that warning, by making some of its local variables 'const'.

Patch "ipv4: ipconfig: avoid unused ic_proto_used symbol" has been added to the 4.4-stable tree

When CONFIG_PROC_FS, CONFIG_IP_PNP_BOOTP, CONFIG_IP_PNP_DHCP and CONFIG_IP_PNP_RARP are all disabled, we get a warning about the ic_proto_used variable being unused: net/ipv4/ipconfig.c:146:12: error: 'ic_proto_used' defined but not used [-Werror=unused-variable] This avoids the warning, by making the definition conditional on whether a dynamic IP configuration protocol is configured. If not, we know that the value is always zero, so we can optimize away the variable and all code that depends on it. Signed-off-by: Arnd Bergmann <arnd(a)arndb.de> Signed-off-by: David S.

Rodriguez" <mcgrof(a)kernel.org> Date: Tue, 7 Jun 2016 16:52:27 -0700 Subject: i2c: remove __init from i2c_register_board_info() From: Luis R. Rodriguez <mcgrof(a)kernel.org> commit 5abe9b26847c65a698f38744a52635b287514294 upstream. As of next-20160607 with allyesconfig we get this linker failure: MODPOST vmlinux.o WARNING: vmlinux.o(.text+0x21bc0d): Section mismatch in reference from the function intel_scu_devices_create() to the function .init.text:i2c_register_board_info() This is caused by the fact that intel_scu_devices_create() calls i2c_register_board_info() and intel_scu_devices_create() is not annotated with __init. This typically involves manual code inspection and if one is certain this is correct we would just peg intel_scu_devices_create() with a __ref annotation. In this case this would be wrong though as the intel_scu_devices_create() call is exported, and used in the ipc_probe() on drivers/platform/x86/intel_scu_ipc.c. The issue is that even though builtin_pci_driver(ipc_driver) is used this just exposes the probe routine, which can occur at any point in time if this bus supports hotplug. A race can happen between kernel_init_freeable() that calls the init calls (in this case registeres the intel_scu_ipc.c driver, and later free_initmem(), which would free the i2c_register_board_info(). If a probe happens later in boot i2c_register_board_info() would not be present and we should get a page fault. Signed-off-by: Luis R.

Patch "hwrng: exynos - use __maybe_unused to hide pm functions" has been added to the 4.4-stable tree

The exynos random driver uses #ifdef to check for CONFIG_PM, but then uses SIMPLE_DEV_PM_OPS, which leaves the references out when CONFIG_PM_SLEEP is not defined, so we get a warning with PM=y && PM_SLEEP=n: drivers/char/hw_random/exynos-rng.c:166:12: error: 'exynos_rng_suspend' defined but not used [-Werror=unused-function] drivers/char/hw_random/exynos-rng.c:171:12: error: 'exynos_rng_resume' defined but not used [-Werror=unused-function] This removes the incorrect #ifdef and instead uses a __maybe_unused annotation to let the compiler know it can silently drop the function definition.
