      "message": "kdump: protect vmcoreinfo data under the crash memory\n\nCurrently vmcoreinfo data is updated at boot time subsys_initcall(), it\nhas the risk of being modified by some wrong code during system is\nrunning.\n\nAs a result, vmcore dumped may contain the wrong vmcoreinfo.  Later on,\nwhen using \"crash\", \"makedumpfile\", etc utility to parse this vmcore, we\nprobably will get \"Segmentation fault\" or other unexpected errors.\n\nE.g.  1) wrong code overwrites vmcoreinfo_data; 2) further crashes the\nsystem; 3) trigger kdump, then we obviously will fail to recognize the\ncrash context correctly due to the corrupted vmcoreinfo.\n\nNow except for vmcoreinfo, all the crash data is well\nprotected(including the cpu note which is fully updated in the crash\npath, thus its correctness is guaranteed).  Given that vmcoreinfo data\nis a large chunk prepared for kdump, we better protect it as well.\n\nTo solve this, we relocate and copy vmcoreinfo_data to the crash memory\nwhen kdump is loading via kexec syscalls.  Because the whole crash\nmemory will be protected by existing arch_kexec_protect_crashkres()\nmechanism, we naturally protect vmcoreinfo_data from write(even read)\naccess under kernel direct mapping after kdump is loaded.\n\nSince kdump is usually loaded at the very early stage after boot, we can\ntrust the correctness of the vmcoreinfo data copied.\n\nOn the other hand, we still need to operate the vmcoreinfo safe copy\nwhen crash happens to generate vmcoreinfo_note again, we rely on vmap()\nto map out a new kernel virtual address and update to use this new one\ninstead in the following crash_save_vmcoreinfo().\n\nBTW, we do not touch vmcoreinfo_note, because it will be fully updated\nusing the protected vmcoreinfo_data after crash which is surely correct\njust like the cpu crash note.\n\nLink: http://lkml.kernel.org/r/1493281021-20737-3-git-send-email-xlpang@redhat.com\nSigned-off-by: Xunlei Pang \u003cxlpang@redhat.com\u003e\nTested-by: Michael Holzheu \u003cholzheu@linux.vnet.ibm.com\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nCc: Dave Young \u003cdyoung@redhat.com\u003e\nCc: Eric Biederman \u003cebiederm@xmission.com\u003e\nCc: Hari Bathini \u003chbathini@linux.vnet.ibm.com\u003e\nCc: Juergen Gross \u003cjgross@suse.com\u003e\nCc: Mahesh Salgaonkar \u003cmahesh@linux.vnet.ibm.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

And all other arches had\nto do this for CONFIG_KEXEC.  Now with introduction of new config\noption, we can remove crypto dependency from other arches.\n\nNow CONFIG_KEXEC_FILE is available only on x86_64.

      "message": "kexec: verify the signature of signed PE bzImage\n\nThis is the final piece of the puzzle of verifying kernel image signature\nduring kexec_file_load() syscall.\n\nThis patch calls into PE file routines to verify signature of bzImage.  If\nsignature are valid, kexec_file_load() succeeds otherwise it fails.\n\nTwo new config options have been introduced.  First one is\nCONFIG_KEXEC_VERIFY_SIG.  This option enforces that kernel has to be\nvalidly signed otherwise kernel load will fail.  If this option is not\nset, no signature verification will be done.  Only exception will be when\nsecureboot is enabled.  In that case signature verification should be\nautomatically enforced when secureboot is enabled.  But that will happen\nwhen secureboot patches are merged.\n\nSecond config option is CONFIG_KEXEC_BZIMAGE_VERIFY_SIG.  This option\nenables signature verification support on bzImage.  If this option is not\nset and previous one is set, kernel image loading will fail because kernel\ndoes not have support to verify signature of bzImage.\n\nI tested these patches with both \"pesign\" and \"sbsign\" signed bzImages.\n\nI used signing_key.priv key and signing_key.x509 cert for signing as\ngenerated during kernel build process (if module signing is enabled).\n\nUsed following method to sign bzImage.\n\npesign\n\u003d\u003d\u003d\u003d\u003d\u003d\n- Convert DER format cert to PEM format cert\nopenssl x509 -in signing_key.x509 -inform DER -out signing_key.x509.PEM -outform\nPEM\n\n- Generate a .p12 file from existing cert and private key file\nopenssl pkcs12 -export -out kernel-key.p12 -inkey signing_key.priv -in\nsigning_key.x509.PEM\n\n- Import .p12 file into pesign db\npk12util -i /tmp/kernel-key.p12 -d /etc/pki/pesign\n\n- Sign bzImage\npesign -i /boot/vmlinuz-3.16.0-rc3+ -o /boot/vmlinuz-3.16.0-rc3+.signed.pesign\n-c \"Glacier signing key - Magrathea\" -s\n\nsbsign\n\u003d\u003d\u003d\u003d\u003d\u003d\nsbsign --key signing_key.priv --cert signing_key.x509.PEM --output\n/boot/vmlinuz-3.16.0-rc3+.signed.sbsign /boot/vmlinuz-3.16.0-rc3+\n\nPatch details:\n\nWell all the hard work is done in previous patches.  Now bzImage loader\nhas just call into that code and verify whether bzImage signature are\nvalid or not.\n\nAlso create two config options.  First one is CONFIG_KEXEC_VERIFY_SIG.\nThis option enforces that kernel has to be validly signed otherwise kernel\nload will fail.  If this option is not set, no signature verification will\nbe done.  Only exception will be when secureboot is enabled.

Thus, only the primary threads of all the cores are online\nduring kexec, and hence this is a sure-shot receipe for disaster, as explained\nin commit e8e5c2155b (powerpc/kexec: Fix orphaned offline CPUs across kexec),\nas well as in the comment above wake_offline_cpus().\n\nIt turns out that cpu_up() was returning -EBUSY because the variable\n\u0027cpu_hotplug_disabled\u0027 was set to 1; and this disabling of CPU hotplug was done\nby migrate_to_reboot_cpu() inside kernel_kexec().\n\nNow, migrate_to_reboot_cpu() was originally written with the assumption that\nany further code will not need to perform CPU hotplug, since we are anyway in\nthe reboot path. However, kexec is clearly not such a case, since we depend on\nonlining CPUs, atleast on powerpc.\n\nSo re-enable cpu-hotplug after returning from migrate_to_reboot_cpu() in the\nkexec path, to fix this regression in kexec on powerpc.\n\nAlso, wrap the cpu_up() in powerpc kexec code within a WARN_ON(), so that we\ncan catch such issues more easily in the future.\n\nFixes: c97102ba963 (kexec: migrate to reboot cpu)\nCc: stable@vger.kernel.org\nSigned-off-by: Srivatsa S.

So using module_init as an\nalias for __initcall can be somewhat misleading.\n\nFix these up now, so that we can relocate module_init from init.h into\nmodule.h in the future.  If we don\u0027t do this, we\u0027d have to add module.h\nto obviously non-modular code, and that would be a worse thing.\n\nThe audit targets the following module_init users for change:\n kernel/user.c                  obj-y\n kernel/kexec.c                 bool KEXEC (one instance per arch)\n kernel/profile.c               bool PROFILING\n kernel/hung_task.c             bool DETECT_HUNG_TASK\n kernel/sched/stats.c           bool SCHEDSTATS\n kernel/user_namespace.c        bool USER_NS\n\nNote that direct use of __initcall is discouraged, vs.  one of the\npriority categorized subgroups.  As __initcall gets mapped onto\ndevice_initcall, our use of subsys_initcall (which makes sense for these\nfiles) will thus change this registration from level 6-device to level\n4-subsys (i.e.  slightly earlier).

      "message": "kexec: add sysctl to disable kexec_load\n\nFor general-purpose (i.e.  distro) kernel builds it makes sense to build\nwith CONFIG_KEXEC to allow end users to choose what kind of things they\nwant to do with kexec.  However, in the face of trying to lock down a\nsystem with such a kernel, there needs to be a way to disable kexec_load\n(much like module loading can be disabled).  Without this, it is too easy\nfor the root user to modify kernel memory even when CONFIG_STRICT_DEVMEM\nand modules_disabled are set.  With this change, it is still possible to\nload an image for use later, then disable kexec_load so the image (or lack\nof image) can\u0027t be altered.\n\nThe intention is for using this in environments where \"perfect\"\nenforcement is hard.  Without a verified boot, along with verified\nmodules, and along with verified kexec, this is trying to give a system a\nbetter chance to defend itself (or at least grow the window of\ndiscoverability) against attack in the face of a privilege escalation.\n\nIn my mind, I consider several boot scenarios:\n\n1) Verified boot of read-only verified root fs loading fd-based\n   verification of kexec images.\n2) Secure boot of writable root fs loading signed kexec images.\n3) Regular boot loading kexec (e.g. kcrash) image early and locking it.\n4) Regular boot with no control of kexec image at all.\n\n1 and 2 don\u0027t exist yet, but will soon once the verified kexec series has\nlanded.  4 is the state of things now.  The gap between 2 and 4 is too\nlarge, so this change creates scenario 3, a middle-ground above 4 when 2\nand 1 are not possible for a system.\n\nSigned-off-by: Kees Cook \u003ckeescook@chromium.org\u003e\nAcked-by: Rik van Riel \u003criel@redhat.com\u003e\nCc: Vivek Goyal \u003cvgoyal@redhat.com\u003e\nCc: Eric Biederman \u003cebiederm@xmission.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n"

In the process it also\nremoved the code in native_machine_shutdown() which are moving reboot\nprocess to reboot_cpu/cpu0.\n\nI guess that thought must have been that all reboot paths are calling\nmigrate_to_reboot_cpu(), so we don\u0027t need this special handling.  But\nkexec reboot path (kernel_kexec()) is not calling\nmigrate_to_reboot_cpu() so above change broke kexec.  Now reboot can\nhappen on non-boot cpu and when INIT is sent in second kerneo to bring\nup BP, it brings down the machine.\n\nSo start calling migrate_to_reboot_cpu() in kexec reboot path to avoid\nthis problem.\n\nBisected by WANG Chao.\n\nReported-by: Matthew Whitehead \u003cmwhitehe@redhat.com\u003e\nReported-by: Dave Young \u003cdyoung@redhat.com\u003e\nSigned-off-by: Vivek Goyal \u003cvgoyal@redhat.com\u003e\nTested-by: Baoquan He \u003cbhe@redhat.com\u003e\nTested-by: WANG Chao \u003cchaowang@redhat.com\u003e\nAcked-by: H.

But, _mapcount shares its memory with other\nfields for SLAB/SLUB when PG_slab is set, so we need to check if PG_slab\nis set or not before looking up _mapcount value.

Two new\nfunctions crash_map_reserved_pages() and crash_unmap_reserved_pages() are\nadded that can be implemented by architecture code.  The\ncrash_map_reserved_pages() function is called before and\ncrash_unmap_reserved_pages() after the crashkernel segments are loaded.  The\nfunctions are also called in crash_shrink_memory() to create/remove page\ntables when the crashkernel memory size is reduced.\n\nTo support architectures that have large pages this patch also introduces\na new define KEXEC_CRASH_MEM_ALIGN. The crashkernel start and size must\nalways be aligned with KEXEC_CRASH_MEM_ALIGN.\n\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nAcked-by: Vivek Goyal \u003cvgoyal@redhat.com\u003e\nSigned-off-by: Michael Holzheu \u003cholzheu@linux.vnet.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n"

      "message": "[S390] kdump: Initialize vmcoreinfo note at startup\n\nCurrently the vmcoreinfo note is only initialized in case of kdump. On s390\nit is possible to create kernel dumps with other dump mechanisms than kdump\n(e.g. via hypervisor dump or stand-alone dump tools). For those dumps it\nwould also be desirable to include the vmcoreinfo data. To accomplish this,\nwith this patch the vmcoreinfo ELF note is always initialized, not only in\ncase of a (kdump) crash. On s390 we will add an ABI defined pointer at\na well known address to vmcoreinfo so that dump analysis tools are able to\nfind this information.\n\nIn particular on s390 we have a tool named zgetdump. With this tool it is\npossible to convert dump formats on the fly using fuse. E.g. you can mount a\ns390 stand-alone dump as ELF dump. When this is done, the tool finds the\nvmcoreinfo in the stand-alone dump via the well known ABI defined address and\nit creates the respective VMCOREINFO ELF note in the output ELF dump. This then\ncan be used e.g. by makedumpfile for dump filtering.  No more need for a\nvmlinux file with debug information.\n\nSo this will look like the following:\n$ zgetdump --mount standalone.dump -f elf /mnt\n$ ls /mnt\n  dump.elf\n$ readelf -n /mnt/dump.elf\n$ ...\n  VMCOREINFO            0x00000474      Unknown note type: (0x00000000)\n$ makedumpfile -c -d 31 /mnt/dump.elf dump.kdump\n\nCc: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nAcked-by: Vivek Goyal \u003cvgoyal@redhat.com\u003e\nSigned-off-by: Michael Holzheu \u003cholzheu@linux.vnet.ibm.com\u003e\nSigned-off-by: Martin Schwidefsky \u003cschwidefsky@de.ibm.com\u003e\n"

      "message": "PM: Rework handling of interrupts during suspend-resume\n\nUse the functions introduced in by the previous patch,\nsuspend_device_irqs(), resume_device_irqs() and check_wakeup_irqs(),\nto rework the handling of interrupts during suspend (hibernation) and\nresume.  Namely, interrupts will only be disabled on the CPU right\nbefore suspending sysdevs, while device drivers will be prevented\nfrom receiving interrupts, with the help of the new helper function,\nbefore their \"late\" suspend callbacks run (and analogously during\nresume).\n\nIn addition, since the device interrups are now disabled before the\nCPU has turned all interrupts off and the CPU will ACK the interrupts\nsetting the IRQ_PENDING bit for them, check in sysdev_suspend() if\nany wake-up interrupts are pending and abort suspend if that\u0027s the\ncase.\n\nSigned-off-by: Rafael J.
