It adds a new syscall\npaccept. This syscall differs from accept in that it adds (at the userlevel)\ntwo additional parameters:\n\n- a signal mask\n- a flags value\n\nThe flags parameter can be used to set flag like SOCK_CLOEXEC. This is\nimlpemented here as well. Some people argued that this is a property which\nshould be inherited from the file desriptor for the server but this is against\nPOSIX. Additionally, we really want the signal mask parameter as well\n(similar to pselect, ppoll, etc). So an interface change in inevitable.\n\nThe flag value is the same as for socket and socketpair. I think diverging\nhere will only create confusion. Similar to the filesystem interfaces where\nthe use of the O_* constants differs, it is acceptable here.\n\nThe signal mask is handled as for pselect etc. The mask is temporarily\ninstalled for the thread and removed before the call returns. I modeled the\ncode after pselect. If there is a problem it\u0027s likely also in pselect.\n\nFor architectures which use socketcall I maintained this interface instead of\nadding a system call.

This can be a problem if an application relied on unlimited\novercommit semantics for private mappings. An example of this would be an\napplication which maps a huge area with the intention of using it very\nsparsely. These application would benefit from being able to opt-out of\nthe strict overcommit. It should be noted that prior to hugetlb\nsupporting demand faulting all mappings were fully populated and so\napplications of this type should be rare.\n\nThis patch stack implements the MAP_NORESERVE mmap() flag for huge page\nmappings. This flag has the same meaning as for small page mappings,\nsuppressing reservations for that mapping.\n\nThanks to Mel Gorman for reviewing a number of early versions of these\npatches.\n\nThis patch:\n\nWhen a small page mapping is created with mmap() reservations are created\nby default for any memory pages required. When the region is read/write\nthe reservation is increased for every page, no reservation is needed for\nread-only regions (as they implicitly share the zero page). Reservations\nare tracked via the VM_ACCOUNT vma flag which is present when the region\nhas reservation backing it. When we convert a region from read-only to\nread-write new reservations are aquired and VM_ACCOUNT is set. However,\nwhen a read-only map is created with MAP_NORESERVE it is indistinguishable\nfrom a normal mapping. When we then convert that to read/write we are\nforced to incorrectly create reservations for it as we have no record of\nthe original MAP_NORESERVE.\n\nThis patch introduces a new vma flag VM_NORESERVE which records the\npresence of the original MAP_NORESERVE flag. This allows us to\ndistinguish these two circumstances and correctly account the reserve.\n\nAs well as fixing this FIXME in the code, this makes it much easier to\nintroduce MAP_NORESERVE support for huge pages as this flag is available\nconsistantly for the life of the mapping. VM_ACCOUNT on the other hand is\nheavily used at the generic level in association with small pages.\n\nSigned-off-by: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: Mel Gorman \u003cmel@csn.ul.ie\u003e\nCc: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: Johannes Weiner \u003channes@saeurebad.de\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Michael Kerrisk \u003cmtk.manpages@googlemail.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "04f2cbe35699d22dbf428373682ead85ca1240f5", "tree": "1987a2c704cc97d8adf603054c9d89d18b9b30e0", "parents": [ "a1e78772d72b2616ed20e54896e68e0e7044854e" ], "author": { "name": "Mel Gorman", "email": "mel@csn.ul.ie", "time": "Wed Jul 23 21:27:25 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jul 24 10:47:16 2008 -0700" }, "message": "hugetlb: guarantee that COW faults for a process that called mmap(MAP_PRIVATE) on hugetlbfs will succeed\n\nAfter patch 2 in this series, a process that successfully calls mmap() for\na MAP_PRIVATE mapping will be guaranteed to successfully fault until a\nprocess calls fork(). At that point, the next write fault from the parent\ncould fail due to COW if the child still has a reference.\n\nWe only reserve pages for the parent but a copy must be made to avoid\nleaking data from the parent to the child after fork(). Reserves could be\ntaken for both parent and child at fork time to guarantee faults but if\nthe mapping is large it is highly likely we will not have sufficient pages\nfor the reservation, and it is common to fork only to exec() immediatly\nafter. A failure here would be very undesirable.\n\nNote that the current behaviour of mainline with MAP_PRIVATE pages is\npretty bad. The following situation is allowed to occur today.\n\n1. Process calls mmap(MAP_PRIVATE)\n2. Process calls mlock() to fault all pages and makes sure it succeeds\n3. Process forks()\n4. Process writes to MAP_PRIVATE mapping while child still exists\n5. If the COW fails at this point, the process gets SIGKILLed even though it\n had taken care to ensure the pages existed\n\nThis patch improves the situation by guaranteeing the reliability of the\nprocess that successfully calls mmap(). When the parent performs COW, it\nwill try to satisfy the allocation without using reserves. If that fails\nthe parent will steal the page leaving any children without a page.\nFaults from the child after that point will result in failure. If the\nchild COW happens first, an attempt will be made to allocate the page\nwithout reserves and the child will get SIGKILLed on failure.\n\nTo summarise the new behaviour:\n\n1. If the original mapper performs COW on a private mapping with multiple\n references, it will attempt to allocate a hugepage from the pool or\n the buddy allocator without using the existing reserves. On fail, VMAs\n mapping the same area are traversed and the page being COW\u0027d is unmapped\n where found. It will then steal the original page as the last mapper in\n the normal way.\n\n2. The VMAs the pages were unmapped from are flagged to note that pages\n with data no longer exist. Future no-page faults on those VMAs will\n terminate the process as otherwise it would appear that data was corrupted.\n A warning is printed to the console that this situation occured.\n\n2. If the child performs COW first, it will attempt to satisfy the COW\n from the pool if there are enough pages or via the buddy allocator if\n overcommit is allowed and the buddy allocator can satisfy the request. If\n it fails, the child will be killed.\n\nIf the pool is large enough, existing applications will not notice that\nthe reserves were a factor. Existing applications depending on the\nno-reserves been set are unlikely to exist as for much of the history of\nhugetlbfs, pages were prefaulted at mmap(), allocating the pages at that\npoint or failing the mmap().\n\n[npiggin@suse.de: fix CONFIG_HUGETLB\u003dn build]\nSigned-off-by: Mel Gorman \u003cmel@csn.ul.ie\u003e\nAcked-by: Adam Litke \u003cagl@us.ibm.com\u003e\nCc: Andy Whitcroft \u003capw@shadowen.org\u003e\nCc: William Lee Irwin III \u003cwli@holomorphy.com\u003e\nCc: Hugh Dickins \u003chugh@veritas.com\u003e\nCc: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n" }, { "commit": "a1e78772d72b2616ed20e54896e68e0e7044854e", "tree": "d752dd96c2a4fcc555779a7aa99f95069c9b95ae", "parents": [ "fc1b8a73dd71226902a11928dd5500326e101df9" ], "author": { "name": "Mel Gorman", "email": "mel@csn.ul.ie", "time": "Wed Jul 23 21:27:23 2008 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@linux-foundation.org", "time": "Thu Jul 24 10:47:16 2008 -0700" }, "message": "hugetlb: reserve huge pages for reliable MAP_PRIVATE hugetlbfs mappings until fork()\n\nThis patch reserves huge pages at mmap() time for MAP_PRIVATE mappings in\na similar manner to the reservations taken for MAP_SHARED mappings.
