commit 3312c951 upstream. 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.

commit ade356b9 upstream. 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. I have done several thousand ARM randconfig kernels with this patch applied and no longer get any warnings in this file. Signed-off-by:

commit 553bbc11 upstream. The latest binutils are warning about a .fill directive with an explicit value in a .bss section: arch/x86/kernel/head_32.S: Assembler messages: arch/x86/kernel/head_32.S:677: Warning: ignoring fill value in section `.bss..page_aligned' arch/x86/kernel/head_32.S:679: Warning: ignoring fill value in section `.bss..page_aligned' This comes from the 'ENTRY()' macro padding the space between the symbols with 'nop' via: .align 4,0x90 Open-coding the .globl directive without the padding avoids that warning, as all the symbols are already page aligned.

commit d612c64d upstream. The spear thermal driver hides its suspend/resume function conditionally based on CONFIG_PM, but references them based on CONFIG_PM_SLEEP, so we get a warning if the former is set but the latter is not: thermal/spear_thermal.c:58:12: warning: 'spear_thermal_suspend' defined but not used [-Wunused-function] thermal/spear_thermal.c:75:12: warning: 'spear_thermal_resume' defined but not used [-Wunused-function] This removes the #ifdef and instead uses a __maybe_uninitialized annotation to avoid the warning and improve compile-time coverage.

commit b7e2d195 upstream. The SoC variant of the ssb code is now optional like the other ones, which means we can build the framwork without any front-end, but that results in a warning: drivers/ssb/main.c:616:12: warning: 'ssb_bus_register' defined but not used [-Wunused-function] This annotates the ssb_bus_register function as __maybe_unused to shut up the warning. A configuration like this will not work on any hardware of course, but we still want this to silently build without warnings if the configuration is allowed in the first place. Signed-off-by:

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.

commit 46a049da upstream. gcc-7 caught what it considers a NULL pointer dereference: sound/pci/hda/patch_ca0132.c: In function 'dspio_scp.constprop': sound/pci/hda/patch_ca0132.c:1487:4: error: argument 1 null where non-null expected [-Werror=nonnull] This is plausible from looking at the function, as we compare 'reply' to NULL earlier in it. I have not tried to analyze if there are constraints that make it impossible to hit the bug, but adding another NULL check in the end kills the warning and makes the function more robust.

commit e572d088 upstream. When doing a kernel build with 'make -s', everything is silenced except the objtool build. That's because the tools tree support for silent builds is some combination of missing and broken. Three changes are needed to fix it: - Makefile: propagate '-s' to the sub-make's MAKEFLAGS variable so the tools Makefiles can see it. - tools/scripts/Makefile.include: fix the tools Makefiles' ability to recognize '-s'. The MAKE_VERSION and MAKEFLAGS checks are copied from the top-level Makefile. This silences the "DESCEND objtool" message. - tools/build/Makefile.build: add support to the tools Build files for recognizing '-s'. Again the MAKE_VERSION and MAKEFLAGS checks are copied from the top-level Makefile. This silences all the object compile/link messages. Reported-and-Tested-by:

commit f46e7cd3 upstream. The advansys probe function tries to handle both ISA and PCI cases, each hidden in an #ifdef when unused. This leads to a warning indicating that when PCI is disabled we could be using uninitialized data: drivers/scsi/advansys.c: In function advansys_board_found : drivers/scsi/advansys.c:11036:5: error: ret may be used uninitialized in this function [-Werror=maybe-uninitialized] drivers/scsi/advansys.c:10928:28: note: ret was declared here drivers/scsi/advansys.c:11309:8: error: share_irq may be used uninitialized in this function [-Werror=maybe-uninitialized] drivers/scsi/advansys.c:10928:6: note: share_irq was declared here This cannot happen in practice because the hardware in question only exists for PCI, but changing the code to just error out here is better for consistency and avoids the warning.

commit fbdf0e28 upstream. I got a warning about broken code on ARM64 with 64K pages: drivers/net/vmxnet3/vmxnet3_drv.c: In function 'vmxnet3_rq_init': drivers/net/vmxnet3/vmxnet3_drv.c:1679:29: error: large integer implicitly truncated to unsigned type [-Werror=overflow] rq->buf_info[0][i].len = PAGE_SIZE; 'len' here is a 16-bit integer, so this clearly won't work. I don't think this driver is used much on anything other than x86, so there is no need to fix this properly and we can work around it with a Kconfig dependency to forbid known-broken configurations. qemu in theory supports it on other architectures too, but presumably only for compatibility with x86 guests that also run on vmware. CONFIG_PAGE_SIZE_64KB is used on hexagon, mips, sh and tile, the other symbols are architecture-specific names for the same thing. Signed-off-by:

commit 01ed1e15 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. Signed-off-by:

[ Upstream commit 6d60ce38 ] If something calls ioremap() with an address not aligned to PAGE_SIZE, the returned address might be not aligned as well. This led to a probe registered on exactly the returned address, but the entire page was armed for mmiotracing. On calling iounmap() the address passed to unregister_kmmio_probe() was PAGE_SIZE aligned by the caller leading to a complete freeze of the machine. We should always page align addresses while (un)registerung mappings, because the mmiotracer works on top of pages, not mappings. We still keep track of the probes based on their real addresses and lengths though, because the mmiotrace still needs to know what are mapped memory regions. Also move the call to mmiotrace_iounmap() prior page aligning the address, so that all probes are unregistered properly, otherwise the kernel ends up failing memory allocations randomly after disabling the mmiotracer.

[ Upstream commit 732706af ] On policies with a transport mode template, we pass the addresses from the flowi to xfrm_state_find(), assuming that the IP addresses (and address family) don't change during transformation. Unfortunately our policy template validation is not strict enough. It is possible to configure policies with transport mode template where the address family of the template does not match the selectors address family. This lead to stack-out-of-bound reads because we compare arddesses of the wrong family. Fix this by refusing such a configuration, address family can not change on transport mode. We use the assumption that, on transport mode, the first templates address family must match the address family of the policy selector. Subsequent transport mode templates must mach the address family of the previous template. Signed-off-by:
