This means that every assignment or\ncomparison is not right. In particular, if this argument does not fit\ninto \"unsigned int\" __set_personality() changes the caller\u0027s personality\nand then sys_personality() returns -EINVAL.\n\nTurn this argument into \"unsigned int\" and avoid overflows. Obviously,\nthis is the user-visible change, we just ignore the upper bits. But this\ncan\u0027t break the sane application.\n\nThere is another thing which can confuse the poorly written applications.\nUser-space thinks that this syscall returns int, not long. This means\nthat the returned value can be negative and look like the error code. But\nnote that libc won\u0027t be confused and thus errno won\u0027t be set, and with\nthis patch the user-space can never get -1 unless sys_personality() really\nfails. And, most importantly, the negative RET !\u003d -1 is only possible if\nthat app previously called personality(RET).\n\nPointed-out-by: Wenming Zhang \u003cwezhang@redhat.com\u003e\nSuggested-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\nSigned-off-by: Oleg Nesterov \u003coleg@redhat.com\u003e\nCc: \"H.

"fs: introduce new truncate sequence\n\nIntroduce a new truncate calling sequence into fs/mm subsystems. Rather than\nsetattr \u003e vmtruncate \u003e truncate, have filesystems call their truncate sequence\nfrom -\u003esetattr if filesystem specific operations are required. vmtruncate is\ndeprecated, and truncate_pagecache and inode_newsize_ok helpers introduced\npreviously should be used.\n\nsimple_setattr is introduced for simple in-ram filesystems to implement\nthe new truncate sequence. Eventually all filesystems should be converted\nto implement a setattr, and the default code in notify_change should go\naway.\n\nsimple_setsize is also introduced to perform just the ATTR_SIZE portion\nof simple_setattr (ie. changing i_size and trimming pagecache).\n\nTo implement the new truncate sequence:\n- filesystem specific manipulations (eg freeing blocks) must be done in\n the setattr method rather than -\u003etruncate.\n- vmtruncate can not be used by core code to trim blocks past i_size in\n the event of write failure after allocation, so this must be performed\n in the fs code.\n- convert usage of helpers block_write_begin, nobh_write_begin,\n cont_write_begin, and *blockdev_direct_IO* to use _newtrunc postfixed\n variants. These avoid calling vmtruncate to trim blocks (see previous).\n- inode_setattr should not be used. generic_setattr is a new function\n to be used to copy simple attributes into the generic inode.\n- make use of the better opportunity to handle errors with the new sequence.\n\nBig problem with the previous calling sequence: the filesystem is not called\nuntil i_size has already changed. This means it is not allowed to fail the\ncall, and also it does not know what the previous i_size was. Also, generic\ncode calling vmtruncate to truncate allocated blocks in case of error had\nno good way to return a meaningful error (or, for example, atomically handle\nblock deallocation).\n\nCc: Christoph Hellwig \u003chch@lst.de\u003e\nAcked-by: Jan Kara \u003cjack@suse.cz\u003e\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "1b061d9247f71cd15edc4c4c4600191a903642c0", "tree": "30d92ca82d8286e7a45fba108230ecd23e61673b", "parents": [ "7ea8085910ef3dd4f3cad6845aaa2b580d39b115" ], "author": { "name": "Christoph Hellwig", "email": "hch@lst.de", "time": "Wed May 26 17:53:41 2010 +0200" }, "committer": { "name": "Al Viro", "email": "viro@zeniv.linux.org.uk", "time": "Thu May 27 22:06:06 2010 -0400" }, "message": "rename the generic fsync implementations\n\nWe don\u0027t name our generic fsync implementations very well currently.\nThe no-op implementation for in-memory filesystems currently is called\nsimple_sync_file which doesn\u0027t make too much sense to start with,\nthe the generic one for simple filesystems is called simple_fsync\nwhich can lead to some confusion.\n\nThis patch renames the generic file fsync method to generic_file_fsync\nto match the other generic_file_* routines it is supposed to be used\nwith, and the no-op implementation to noop_fsync to make it obvious\nwhat to expect.
