make the kernel pass 64-bit inode numbers internally when\ncommunicating to userspace, even on a 32-bit system. They are required\nbecause some filesystems have intrinsic 64-bit inode numbers: NFS3+ and XFS\nfor example. The 64-bit inode numbers are then propagated to userspace\nautomatically where the arch supports it.\n\nProblems have been seen with userspace (eg: ld.so) using the 64-bit inode\nnumber returned by stat64() or getdents64() to differentiate files, and\nfailing because the 64-bit inode number space was compressed to 32-bits, and\nso overlaps occur.\n\nThis patch:\n\nMake filldir_t take a 64-bit inode number and struct kstat carry a 64-bit\ninode number so that 64-bit inode numbers can be passed back to userspace.\n\nThe stat functions then returns the full 64-bit inode number where\navailable and where possible. If it is not possible to represent the inode\nnumber supplied by the filesystem in the field provided by userspace, then\nerror EOVERFLOW will be issued.\n\nSimilarly, the getdents/readdir functions now pass the full 64-bit inode\nnumber to userspace where possible, returning EOVERFLOW instead when a\ndirectory entry is encountered that can\u0027t be properly represented.\n\nNote that this means that some inodes will not be stat\u0027able on a 32-bit\nsystem with old libraries where they were before - but it does mean that\nthere will be no ambiguity over what a 32-bit inode number refers to.\n\nNote similarly that directory scans may be cut short with an error on a\n32-bit system with old libraries where the scan would work before for the\nsame reasons.\n\nIt is judged unlikely that this situation will occur because modern glibc\nuses 64-bit capable versions of stat and getdents class functions\nexclusively, and that older systems are unlikely to encounter\nunrepresentable inode numbers anyway.\n\n[akpm: alpha build fix]\nSigned-off-by: David Howells \u003cdhowells@redhat.com\u003e\nCc: Trond Myklebust \u003ctrond.myklebust@fys.uio.no\u003e\nCc: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "35058687912aa2f0b4554383cc10be4e0683b9a4", "tree": "3e18d13aef6682553887076c1e9872e91e6fc5c4", "parents": [ "dc64ddf4918f0da52df10d83c2a5941a547c2035" ], "author": { "name": "Herbert Xu", "email": "herbert@gondor.apana.org.au", "time": "Thu Aug 24 19:10:20 2006 +1000" }, "committer": { "name": "Herbert Xu", "email": "herbert@gondor.apana.org.au", "time": "Thu Sep 21 11:46:21 2006 +1000" }, "message": "[CRYPTO] users: Use crypto_hash interface instead of crypto_digest\n\nThis patch converts all remaining crypto_digest users to use the new\ncrypto_hash interface.\n\nSigned-off-by: Herbert Xu \u003cherbert@gondor.apana.org.au\u003e\n" }, { "commit": "c2642ab05b855d2d3b850ddf90dbb02b1b9358ac", "tree": "38625ce3e2d5adb2d669875a41b2698b289d8ddb", "parents": [ "d22749b62f3e12de26b86a200f9a5bf7afe3590e" ], "author": { "name": "J.
