As a result,\n{pte,pmd,pud}_pfn() will return the wrong PFN value, i.e. all ones\n(adjusted by the max PFN mask) instead of zero. A zeroed entry is ok\nbecause the page at physical address 0 is reserved early in boot\nspecifically to mitigate L1TF, so explicitly exempt them from the\ninversion when reading the PFN.\n\nManifested as an unexpected mprotect(..., PROT_NONE) failure when called\non a VMA that has VM_PFNMAP and was mmap\u0027d to as something other than\nPROT_NONE but never used. mprotect() sends the PROT_NONE request down\nprot_none_walk(), which walks the PTEs to check the PFNs.\nprot_none_pte_entry() gets the bogus PFN from pte_pfn() and returns\n-EACCES because it thinks mprotect() is trying to adjust a high MMIO\naddress.\n\n[ This is a very modified version of Sean\u0027s original patch, but all\n credit goes to Sean for doing this and also pointing out that\n sometimes the __pte_needs_invert() function only gets the protection\n bits, not the full eventual pte. But zero remains special even in\n just protection bits, so that\u0027s ok. - Linus ]\n\nFixes: f22cc87f6c1f (\"x86/speculation/l1tf: Invert all not present mappings\")\nSigned-off-by: Sean Christopherson \u003csean.j.christopherson@intel.com\u003e\nAcked-by: Andi Kleen \u003cak@linux.intel.com\u003e\nCc: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: Josh Poimboeuf \u003cjpoimboe@redhat.com\u003e\nCc: Michal Hocko \u003cmhocko@suse.com\u003e\nCc: Vlastimil Babka \u003cvbabka@suse.cz\u003e\nCc: Dave Hansen \u003cdave.hansen@intel.com\u003e\nCc: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n\n" }, { "commit": "e8c3aced75bd8803f62ead25941fd68302f9efcb", "tree": "da2be3a756d167716968690c5b846ee84aef05f2", "parents": [ "69622a5cbea9a1e36f6bef79d5d6267cff19fe0a" ], "author": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Fri Aug 17 21:03:49 2018 +0200" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Fri Aug 17 21:03:49 2018 +0200" }, "message": "Linux 4.18.2\n" }, { "commit": "69622a5cbea9a1e36f6bef79d5d6267cff19fe0a", "tree": "8e45414ce83b17e664e2a7803707bd278314e012", "parents": [ "c414efdf39458438c965b403a47578dcf3213e10" ], "author": { "name": "Toshi Kani", "email": "toshi.kani@hpe.com", "time": "Wed Jun 27 08:13:48 2018 -0600" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Fri Aug 17 21:03:49 2018 +0200" }, "message": "x86/mm: Add TLB purge to free pmd/pte page interfaces\n\ncommit 5e0fb5df2ee871b841f96f9cb6a7f2784e96aa4e upstream.\n\nioremap() calls pud_free_pmd_page() / pmd_free_pte_page() when it creates\na pud / pmd map.

Therefore, only the first\nVMAC invocation with a given key calculates the correct digest.\n\nFix these bugs by splitting the per-tfm state from the per-request state\nand using the proper init/update/final sequencing for requests.\n\nReproducer for the crash:\n\n #include \u003clinux/if_alg.h\u003e\n #include \u003csys/socket.h\u003e\n #include \u003cunistd.h\u003e\n\n int main()\n {\n int fd;\n struct sockaddr_alg addr \u003d {\n .salg_type \u003d \"hash\",\n .salg_name \u003d \"vmac(aes)\",\n };\n char buf[256] \u003d { 0 };\n\n fd \u003d socket(AF_ALG, SOCK_SEQPACKET, 0);\n bind(fd, (void *)\u0026addr, sizeof(addr));\n setsockopt(fd, SOL_ALG, ALG_SET_KEY, buf, 16);\n fork();\n fd \u003d accept(fd, NULL, NULL);\n for (;;)\n write(fd, buf, 256);\n }\n\nThe immediate cause of the crash is that vmac_ctx_t.partial_size exceeds\nVMAC_NHBYTES, causing vmac_final() to memset() a negative length.\n\nReported-by: syzbot+264bca3a6e8d645550d3@syzkaller.appspotmail.com\nFixes: f1939f7c5645 (\"crypto: vmac - New hash algorithm for intel_txt support\")\nCc: \u003cstable@vger.kernel.org\u003e # v2.6.32+\nSigned-off-by: Eric Biggers \u003cebiggers@google.com\u003e\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n\n" }, { "commit": "bbf934bc6b641f5a0aa92b9f5099b04f4939486f", "tree": "4550ea79e86f36c55b3bb853d19cd369879db1d6", "parents": [ "6223c1f703e514e20a8e4802a10f3f09c0817123" ], "author": { "name": "Eric Biggers", "email": "ebiggers@google.com", "time": "Mon Jun 18 10:22:37 2018 -0700" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Fri Aug 17 21:03:48 2018 +0200" }, "message": "crypto: vmac - require a block cipher with 128-bit block size\n\ncommit 73bf20ef3df262026c3470241ae4ac8196943ffa upstream.\n\nThe VMAC template assumes the block cipher has a 128-bit block size, but\nit failed to check for that.

They are also read-write, which means they\u0027re much more\nlikely to contain secrets.\n\nBefore this patch:\n\ncurrent_kernel:---[ High Kernel Mapping ]---\ncurrent_kernel-0xffffffff80000000-0xffffffff81000000 16M pmd\ncurrent_kernel-0xffffffff81000000-0xffffffff81e00000 14M ro PSE GLB x pmd\ncurrent_kernel-0xffffffff81e00000-0xffffffff81e11000 68K ro GLB x pte\ncurrent_kernel-0xffffffff81e11000-0xffffffff82000000 1980K RW GLB NX pte\ncurrent_kernel-0xffffffff82000000-0xffffffff82600000 6M ro PSE GLB NX pmd\ncurrent_kernel-0xffffffff82600000-0xffffffff82c00000 6M RW PSE GLB NX pmd\ncurrent_kernel-0xffffffff82c00000-0xffffffff82e00000 2M RW GLB NX pte\ncurrent_kernel-0xffffffff82e00000-0xffffffff83200000 4M RW PSE GLB NX pmd\ncurrent_kernel-0xffffffff83200000-0xffffffffa0000000 462M pmd\n\n current_user:---[ High Kernel Mapping ]---\n current_user-0xffffffff80000000-0xffffffff81000000 16M pmd\n current_user-0xffffffff81000000-0xffffffff81e00000 14M ro PSE GLB x pmd\n current_user-0xffffffff81e00000-0xffffffff81e11000 68K ro GLB x pte\n current_user-0xffffffff81e11000-0xffffffff82000000 1980K RW GLB NX pte\n current_user-0xffffffff82000000-0xffffffff82600000 6M ro PSE GLB NX pmd\n current_user-0xffffffff82600000-0xffffffffa0000000 474M pmd\n\nAfter this patch:\n\ncurrent_kernel:---[ High Kernel Mapping ]---\ncurrent_kernel-0xffffffff80000000-0xffffffff81000000 16M pmd\ncurrent_kernel-0xffffffff81000000-0xffffffff81e00000 14M ro PSE GLB x pmd\ncurrent_kernel-0xffffffff81e00000-0xffffffff81e11000 68K ro GLB x pte\ncurrent_kernel-0xffffffff81e11000-0xffffffff82000000 1980K RW NX pte\ncurrent_kernel-0xffffffff82000000-0xffffffff82600000 6M ro PSE GLB NX pmd\ncurrent_kernel-0xffffffff82600000-0xffffffff82c00000 6M RW PSE NX pmd\ncurrent_kernel-0xffffffff82c00000-0xffffffff82e00000 2M RW NX pte\ncurrent_kernel-0xffffffff82e00000-0xffffffff83200000 4M RW PSE NX pmd\ncurrent_kernel-0xffffffff83200000-0xffffffffa0000000 462M pmd\n\n current_user:---[ High Kernel Mapping ]---\n current_user-0xffffffff80000000-0xffffffff81000000 16M pmd\n current_user-0xffffffff81000000-0xffffffff81e00000 14M ro PSE GLB x pmd\n current_user-0xffffffff81e00000-0xffffffff81e11000 68K ro GLB x pte\n current_user-0xffffffff81e11000-0xffffffff82000000 1980K RW NX pte\n current_user-0xffffffff82000000-0xffffffff82600000 6M ro PSE GLB NX pmd\n current_user-0xffffffff82600000-0xffffffffa0000000 474M pmd\n\nFixes: 0f561fce4d69 (\"x86/pti: Enable global pages for shared areas\")\nReported-by: Hugh Dickins \u003chughd@google.com\u003e\nSigned-off-by: Dave Hansen \u003cdave.hansen@linux.intel.com\u003e\nSigned-off-by: Thomas Gleixner \u003ctglx@linutronix.de\u003e\nCc: keescook@google.com\nCc: aarcange@redhat.com\nCc: jgross@suse.com\nCc: jpoimboe@redhat.com\nCc: gregkh@linuxfoundation.org\nCc: peterz@infradead.org\nCc: torvalds@linux-foundation.org\nCc: bp@alien8.de\nCc: luto@kernel.org\nCc: ak@linux.intel.com\nCc: Kees Cook \u003ckeescook@google.com\u003e\nCc: Andrea Arcangeli \u003caarcange@redhat.com\u003e\nCc: Juergen Gross \u003cjgross@suse.com\u003e\nCc: Josh Poimboeuf \u003cjpoimboe@redhat.com\u003e\nCc: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\nCc: Peter Zijlstra \u003cpeterz@infradead.org\u003e\nCc: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nCc: Borislav Petkov \u003cbp@alien8.de\u003e\nCc: Andy Lutomirski \u003cluto@kernel.org\u003e\nCc: Andi Kleen \u003cak@linux.intel.com\u003e\nLink: https://lkml.kernel.org/r/20180802225825.A100C071@viggo.jf.intel.com\nSigned-off-by: Greg Kroah-Hartman \u003cgregkh@linuxfoundation.org\u003e\n\n" }, { "commit": "35cf32831384d6088201321eadbd0e18b5350954", "tree": "d2e6deca68da4c559be340a651365a36937467e9", "parents": [ "031e64661607551fc9832cbcc1544fa504208b05" ], "author": { "name": "Dou Liyang", "email": "douly.fnst@cn.fujitsu.com", "time": "Mon Jul 30 15:59:47 2018 +0800" }, "committer": { "name": "Greg Kroah-Hartman", "email": "gregkh@linuxfoundation.org", "time": "Fri Aug 17 21:03:47 2018 +0200" }, "message": "x86/platform/UV: Mark memblock related init code and data correctly\n\ncommit 24cfd8ca1d28331b9dad3b88d1958c976b2cfab6 upstream.\n\nparse_mem_block_size() and mem_block_size are only used during init.
