This results in code all over the kernel test\n\t-\u003epid \u003d\u003d 1.\n\n\tIntroduce is_init to capture this case.\n\n\tWith multiple pid spaces for all of the cases affected we are\n\tlooking for only the first process on the system, not some other\n\tprocess that has pid \u003d\u003d 1.\n\nSigned-off-by: Eric W.

      "message": "[PATCH] make PROT_WRITE imply PROT_READ\n\nMake PROT_WRITE imply PROT_READ for a number of architectures which don\u0027t\nsupport write only in hardware.\n\nWhile looking at this, I noticed that some architectures which do not\nsupport write only mappings already take the exact same approach.  For\nexample, in arch/alpha/mm/fault.c:\n\n\"\n        if (cause \u003c 0) {\n                if (!(vma-\u003evm_flags \u0026 VM_EXEC))\n                        goto bad_area;\n        } else if (!cause) {\n                /* Allow reads even for write-only mappings */\n                if (!(vma-\u003evm_flags \u0026 (VM_READ | VM_WRITE)))\n                        goto bad_area;\n        } else {\n                if (!(vma-\u003evm_flags \u0026 VM_WRITE))\n                        goto bad_area;\n        }\n\"\n\nThus, this patch brings other architectures which do not support write only\nmappings in-line and consistent with the rest.  I\u0027ve verified the patch on\nia64, x86_64 and x86.\n\nAdditional discussion:\n\nSeveral architectures, including x86, can not support write-only mappings.\nThe pte for x86 reserves a single bit for protection and its two states are\nread only or read/write.  Thus, write only is not supported in h/w.\n\nCurrently, if i \u0027mmap\u0027 a page write-only, the first read attempt on that page\ncreates a page fault and will SEGV.  That check is enforced in\narch/blah/mm/fault.c.  However, if i first write that page it will fault in\nand the pte will be set to read/write.  Thus, any subsequent reads to the page\nwill succeed.  It is this inconsistency in behavior that this patch is\nattempting to address.  Furthermore, if the page is swapped out, and then\nbrought back the first read will also cause a SEGV.  Thus, any arbitrary read\non a page can potentially result in a SEGV.\n\nAccording to the SuSv3 spec, \"if the application requests only PROT_WRITE, the\nimplementation may also allow read access.\" Also as mentioned, some\narchtectures, such as alpha, shown above already take the approach that i am\nsuggesting.\n\nThe counter-argument to this raised by Arjan, is that the kernel is enforcing\nthe write only mapping the best it can given the h/w limitations.  This is\ntrue, however Alan Cox, and myself would argue that the inconsitency in\nbehavior, that is applications can sometimes work/sometimes fails is highly\nundesireable.  If you read through the thread, i think people, came to an\nagreement on the last patch i posted, as nobody has objected to it...\n\nSigned-off-by: Jason Baron \u003cjbaron@redhat.com\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nCc: \"Luck, Tony\" \u003ctony.luck@intel.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Roman Zippel \u003czippel@linux-m68k.org\u003e\nCc: Geert Uytterhoeven \u003cgeert@linux-m68k.org\u003e\nCc: Paul Mackerras \u003cpaulus@samba.org\u003e\nCc: Benjamin Herrenschmidt \u003cbenh@kernel.crashing.org\u003e\nAcked-by: Andi Kleen \u003cak@muc.de\u003e\nAcked-by: Alan Cox \u003calan@lxorguk.ukuu.org.uk\u003e\nCc: Arjan van de Ven \u003carjan@linux.intel.com\u003e\nAcked-by: Paul Mundt \u003clethal@linux-sh.org\u003e\nCc: Kazumoto Kojima \u003ckkojima@rr.iij4u.or.jp\u003e\nCc: Ian Molton \u003cspyro@f2s.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"

      "message": "[PATCH] mm: init_mm without ptlock\n\nFirst step in pushing down the page_table_lock.  init_mm.page_table_lock has\nbeen used throughout the architectures (usually for ioremap): not to serialize\nkernel address space allocation (that\u0027s usually vmlist_lock), but because\npud_alloc,pmd_alloc,pte_alloc_kernel expect caller holds it.\n\nReverse that: don\u0027t lock or unlock init_mm.page_table_lock in any of the\narchitectures; instead rely on pud_alloc,pmd_alloc,pte_alloc_kernel to take\nand drop it when allocating a new one, to check lest a racing task already\ndid.  Similarly no page_table_lock in vmalloc\u0027s map_vm_area.\n\nSome temporary ugliness in __pud_alloc and __pmd_alloc: since they also handle\nuser mms, which are converted only by a later patch, for now they have to lock\ndifferently according to whether or not it\u0027s init_mm.\n\nIf sources get muddled, there\u0027s a danger that an arch source taking\ninit_mm.page_table_lock will be mixed with common source also taking it (or\nneither take it).  So break the rules and make another change, which should\nbreak the build for such a mismatch: remove the redundant mm arg from\npte_alloc_kernel (ppc64 scrapped its distinct ioremap_mm in 2.6.13).\n\nExceptions: arm26 used pte_alloc_kernel on user mm, now pte_alloc_map; ia64\nused pte_alloc_map on init_mm, now pte_alloc_kernel; parisc had bad args to\npmd_alloc and pte_alloc_kernel in unused USE_HPPA_IOREMAP code; ppc64\nmap_io_page forgot to unlock on failure; ppc mmu_mapin_ram and ppc64 im_free\ntook page_table_lock for no good reason.\n\nSigned-off-by: Hugh Dickins \u003chugh@veritas.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n"
