Prepare for\nthis change by updating users of gfp and slab facilities include those\nheaders directly instead of assuming availability. As this conversion\nneeds to touch large number of source files, the following script is\nused as the basis of conversion.\n\n http://userweb.kernel.org/~tj/misc/slabh-sweep.py\n\nThe script does the followings.\n\n* Scan files for gfp and slab usages and update includes such that\n only the necessary includes are there. ie. if only gfp is used,\n gfp.h, if slab is used, slab.h.\n\n* When the script inserts a new include, it looks at the include\n blocks and try to put the new include such that its order conforms\n to its surrounding. It\u0027s put in the include block which contains\n core kernel includes, in the same order that the rest are ordered -\n alphabetical, Christmas tree, rev-Xmas-tree or at the end if there\n doesn\u0027t seem to be any matching order.\n\n* If the script can\u0027t find a place to put a new include (mostly\n because the file doesn\u0027t have fitting include block), it prints out\n an error message indicating which .h file needs to be added to the\n file.\n\nThe conversion was done in the following steps.\n\n1. The initial automatic conversion of all .c files updated slightly\n over 4000 files, deleting around 700 includes and adding ~480 gfp.h\n and ~3000 slab.h inclusions. The script emitted errors for ~400\n files.\n\n2. Each error was manually checked. Some didn\u0027t need the inclusion,\n some needed manual addition while adding it to implementation .h or\n embedding .c file was more appropriate for others. This step added\n inclusions to around 150 files.\n\n3. The script was run again and the output was compared to the edits\n from #2 to make sure no file was left behind.\n\n4. Several build tests were done and a couple of problems were fixed.\n e.g. lib/decompress_*.c used malloc/free() wrappers around slab\n APIs requiring slab.h to be added manually.\n\n5. The script was run on all .h files but without automatically\n editing them as sprinkling gfp.h and slab.h inclusions around .h\n files could easily lead to inclusion dependency hell. Most gfp.h\n inclusion directives were ignored as stuff from gfp.h was usually\n wildly available and often used in preprocessor macros.

Why?\nBecause when we have it like this, the 64-bit system calls now don\u0027t use\nthe \"pos_high\" argument at all, and it makes more sense for the native\nsystem call to simply match the user-mode prototype.\n\nThis results in a much more natural calling convention, and allows the\ncompiler to generate much more straightforward code. On x86-64, we now\ngenerate\n\n testq %rcx, %rcx # pos_l\n js .L122 #,\n movq %rcx, -48(%rbp) # pos_l, pos\n\nfrom the C source\n\n loff_t pos \u003d pos_from_hilo(pos_h, pos_l);\n\t...\n if (pos \u003c 0)\n return -EINVAL;\n\nand the \u0027pos_h\u0027 register isn\u0027t even touched. It used to generate code\nlike\n\n mov %r8d, %r8d # pos_low, pos_low\n salq $32, %rcx #, tmp71\n movq %r8, %rax # pos_low, pos.386\n orq %rcx, %rax # tmp71, pos.386\n js .L122 #,\n movq %rax, -48(%rbp) # pos.386, pos\n\nwhich isn\u0027t _that_ horrible, but it does show how the natural word size\nis just a more sensible interface (same arguments will hold in the user\nlevel glibc wrapper function, of course, so the kernel side is just half\nof the equation!)\n\nNote: in all cases the user code wrapper can again be the same. You can\njust do\n\n\t#define HALF_BITS (sizeof(unsigned long)*4)\n\t__syscall(PWRITEV, fd, iov, count, offset, (offset \u003e\u003e HALF_BITS) \u003e\u003e HALF_BITS);\n\nor something like that. That way the user mode wrapper will also be\nnicely passing in a zero (it won\u0027t actually have to do the shifts, the\ncompiler will understand what is going on) for the last argument.\n\nAnd that is a good idea, even if nobody will necessarily ever care: if\nwe ever do move to a 128-bit lloff_t, this particular system call might\nbe left alone. Of course, that will be the least of our worries if we\nreally ever need to care, so this may not be worth really caring about.\n\n[ Fixed for lost \u0027loff_t\u0027 cast noticed by Andrew Morton ]\n\nAcked-by: Gerd Hoffmann \u003ckraxel@redhat.com\u003e\nCc: H.

This means that\n all the creds can be calculated in advance and then applied at the point\n of no return with no possibility of failure.\n\n I would like to replace bprm-\u003ecap_effective with:\n\n\tcap_isclear(bprm-\u003ecap_effective)\n\n but this seems impossible due to special behaviour for processes of pid 1\n (they always retain their parent\u0027s capability masks where normally they\u0027d\n be changed - see cap_bprm_set_creds()).\n\n The following sequence of events now happens:\n\n (a) At the start of do_execve, the current task\u0027s cred_exec_mutex is\n \t locked to prevent PTRACE_ATTACH from obsoleting the calculation of\n \t creds that we make.\n\n (a) prepare_exec_creds() is then called to make a copy of the current\n \t task\u0027s credentials and prepare it. This copy is then assigned to\n \t bprm-\u003ecred.\n\n \t This renders security_bprm_alloc() and security_bprm_free()\n \t unnecessary, and so they\u0027ve been removed.\n\n (b) The determination of unsafe execution is now performed immediately\n \t after (a) rather than later on in the code. The result is stored in\n \t bprm-\u003eunsafe for future reference.\n\n (c) prepare_binprm() is called, possibly multiple times.\n\n \t (i) This applies the result of set[ug]id binaries to the new creds\n \t attached to bprm-\u003ecred. Personality bit clearance is recorded,\n \t but now deferred on the basis that the exec procedure may yet\n \t fail.\n\n (ii) This then calls the new security_bprm_set_creds(). This should\n\t calculate the new LSM and capability credentials into *bprm-\u003ecred.\n\n\t This folds together security_bprm_set() and parts of\n\t security_bprm_apply_creds() (these two have been removed).\n\t Anything that might fail must be done at this point.\n\n (iii) bprm-\u003ecred_prepared is set to 1.\n\n\t bprm-\u003ecred_prepared is 0 on the first pass of the security\n\t calculations, and 1 on all subsequent passes. This allows SELinux\n\t in (ii) to base its calculations only on the initial script and\n\t not on the interpreter.\n\n (d) flush_old_exec() is called to commit the task to execution. This\n \t performs the following steps with regard to credentials:\n\n\t (i) Clear pdeath_signal and set dumpable on certain circumstances that\n\t may not be covered by commit_creds().\n\n (ii) Clear any bits in current-\u003epersonality that were deferred from\n (c.i).\n\n (e) install_exec_creds() [compute_creds() as was] is called to install the\n \t new credentials. This performs the following steps with regard to\n \t credentials:\n\n (i) Calls security_bprm_committing_creds() to apply any security\n requirements, such as flushing unauthorised files in SELinux, that\n must be done before the credentials are changed.\n\n\t This is made up of bits of security_bprm_apply_creds() and\n\t security_bprm_post_apply_creds(), both of which have been removed.\n\t This function is not allowed to fail; anything that might fail\n\t must have been done in (c.ii).\n\n (ii) Calls commit_creds() to apply the new credentials in a single\n assignment (more or less). Possibly pdeath_signal and dumpable\n should be part of struct creds.\n\n\t (iii) Unlocks the task\u0027s cred_replace_mutex, thus allowing\n\t PTRACE_ATTACH to take place.\n\n (iv) Clears The bprm-\u003ecred pointer as the credentials it was holding\n are now immutable.\n\n (v) Calls security_bprm_committed_creds() to apply any security\n alterations that must be done after the creds have been changed.\n SELinux uses this to flush signals and signal handlers.\n\n (f) If an error occurs before (d.i), bprm_free() will call abort_creds()\n \t to destroy the proposed new credentials and will then unlock\n \t cred_replace_mutex. No changes to the credentials will have been\n \t made.\n\n (2) LSM interface.\n\n A number of functions have been changed, added or removed:\n\n (*) security_bprm_alloc(), -\u003ebprm_alloc_security()\n (*) security_bprm_free(), -\u003ebprm_free_security()\n\n \t Removed in favour of preparing new credentials and modifying those.\n\n (*) security_bprm_apply_creds(), -\u003ebprm_apply_creds()\n (*) security_bprm_post_apply_creds(), -\u003ebprm_post_apply_creds()\n\n \t Removed; split between security_bprm_set_creds(),\n \t security_bprm_committing_creds() and security_bprm_committed_creds().\n\n (*) security_bprm_set(), -\u003ebprm_set_security()\n\n \t Removed; folded into security_bprm_set_creds().\n\n (*) security_bprm_set_creds(), -\u003ebprm_set_creds()\n\n \t New.

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": "3f2e05e90e0846c42626e3d272454f26be34a1bc", "tree": "8a1701fcb7cde32373b6d7ceca09376416bf94eb", "parents": [ "9ec52099e4b8678a60e9f93e41ad87885d64f3e6" ], "author": { "name": "David Howells", "email": "dhowells@redhat.com", "time": "Mon Oct 02 14:12:31 2006 +0100" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Oct 02 08:03:31 2006 -0700" }, "message": "[PATCH] BLOCK: Revert patch to hack around undeclared sigset_t in linux/compat.h\n\nRevert Andrew Morton\u0027s patch to temporarily hack around the lack of a\ndeclaration of sigset_t in linux/compat.h to make the block-disablement\npatches build on IA64.
