Fixed up trivial conflicts: - arch/x86/include/asm/socket.h converted to <asm-generic/socket.h> in the x86 tree. The generic header has the same new #define's, so that works out fine. - drivers/net/tun.c fix conflict between 89f56d1e9 ("tun: reuse struct sock fields") that switched over to using 'tun->socket.sk' instead of the redundantly available (and thus removed) 'tun->sk', and 2b980dbd ("lsm: Add hooks to the TUN driver") which added a new 'tun->sk' use.

I am not quite sure why we have that-many copies of socket.h, and why the values are not the same on all arches either, but for where hex numbers dominate, I use 0x1029 for SO_PROTOCOL as that seems to be the next free unused number across a bunch of operating systems, or so Google results make me want to believe. SO_PROTOCOL for others just uses the next free Linux number, 38. Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: David S. Miller <davem@davemloft.net>

This replaces the parent's session keyring. Because the COW credential code does not permit one process to change another process's credentials directly, the change is deferred until userspace next starts executing again. Normally this will be after a wait*() syscall. To support this, three new security hooks have been provided: cred_alloc_blank() to allocate unset security creds, cred_transfer() to fill in the blank security creds and key_session_to_parent() - which asks the LSM if the process may replace its parent's session keyring. The replacement may only happen if the process has the same ownership details as its parent, and the process has LINK permission on the session keyring, and the session keyring is owned by the process, and the LSM permits it. Note that this requires alteration to each architecture's notify_resume path. This has been done for all arches barring blackfin, m68k* and xtensa, all of which need assembly alteration to support TIF_NOTIFY_RESUME. This allows the replacement to be performed at the point the parent process resumes userspace execution. This allows the userspace AFS pioctl emulation to fully emulate newpag() and the VIOCSETTOK and VIOCSETTOK2 pioctls, all of which require the ability to alter the parent process's PAG membership. However, since kAFS doesn't use PAGs per se, but rather dumps the keys into the session keyring, the session keyring of the parent must be replaced if, for example, VIOCSETTOK is passed the newpag flag. This can be tested with the following program: #include <stdio.h> #include <stdlib.h> #include <keyutils.h> #define KEYCTL_SESSION_TO_PARENT 18 #define OSERROR(X, S) do { if ((long)(X) == -1) { perror(S); exit(1); } } while(0) int main(int argc, char **argv) { key_serial_t keyring, key; long ret; keyring = keyctl_join_session_keyring(argv[1]); OSERROR(keyring, "keyctl_join_session_keyring"); key = add_key("user", "a", "b", 1, keyring); OSERROR(key, "add_key"); ret = keyctl(KEYCTL_SESSION_TO_PARENT); OSERROR(ret, "KEYCTL_SESSION_TO_PARENT"); return 0; } Compiled and linked with -lkeyutils, you should see something like: [dhowells@andromeda ~]$ keyctl show Session Keyring -3 --alswrv 4043 4043 keyring: _ses 355907932 --alswrv 4043 -1 \_ keyring: _uid.4043 [dhowells@andromeda ~]$ /tmp/newpag [dhowells@andromeda ~]$ keyctl show Session Keyring -3 --alswrv 4043 4043 keyring: _ses 1055658746 --alswrv 4043 4043 \_ user: a [dhowells@andromeda ~]$ /tmp/newpag hello [dhowells@andromeda ~]$ keyctl show Session Keyring -3 --alswrv 4043 4043 keyring: hello 340417692 --alswrv 4043 4043 \_ user: a Where the test program creates a new session keyring, sticks a user key named 'a' into it and then installs it on its parent.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mm: Pass virtual address to [__]p{te,ud,md}_free_tlb() Upcoming paches to support the new 64-bit "BookE" powerpc architecture will need to have the virtual address corresponding to PTE page when freeing it, due to the way the HW table walker works. Basically, the TLB can be loaded with "large" pages that cover the whole virtual space (well, sort-of, half of it actually) represented by a PTE page, and which contain an "indirect" bit indicating that this TLB entry RPN points to an array of PTEs from which the TLB can then create direct entries. Thus, in order to invalidate those when PTE pages are deleted, we need the virtual address to pass to tlbilx or tlbivax instructions. The old trick of sticking it somewhere in the PTE page struct page sucks too much, the address is almost readily available in all call sites and almost everybody implemets these as macros, so we may as well add the argument everywhere. I added it to the pmd and pud variants for consistency.

* parisc: fix "delay!" timer handlingGrant Grundler2009-07-031-35/+53
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rewrote timer_interrupt() to properly handle the "delayed!" case. If we used floating point math to compute the number of ticks that had elapsed since the last timer interrupt, it could take up to 12K cycles (emperical!) to handle the interrupt. Existing code assumed it would never take more than 8k cycles. We end up programming Interval Timer to a value less than "current" cycle counter. Thus have to wait until Interval Timer "wrapped" and would then get the "delayed!" printk that I moved below. Since we don't really know what the upper limit is, I prefer to read CR16 again after we've programmed it to make sure we won't have to wait for CR16 to wrap. Further, the printk was between reading CR16 (cycle couner) and writing CR16 (the interval timer). This would cause us to continue to set the interval timer to a value that was "behind" the cycle counter. Rinse and repeat. So no printk's between reading CR16 and setting next interval timer.

The change has had a few days testing with a SMP build of 2.6.22.19 running on a rp3440. This patch is about the correctness of the __ldcw() macro itself.

* kmap_types: make most arches use generic header fileRandy Dunlap2009-06-161-21/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert most arches to use asm-generic/kmap_types.h. Move the KM_FENCE_ macro additions into asm-generic/kmap_types.h, controlled by __WITH_KM_FENCE from each arch's kmap_types.h file. Would be nice to be able to add custom KM_types per arch, but I don't yet see a nice, clean way to do that. Built on x86_64, i386, mips, sparc, alpha(tonyb), powerpc(tonyb), and 68k(tonyb). Note: avr32 should be able to remove KM_PTE2 (since it's not used) and then just use the generic kmap_types.h file. Get avr32 maintainer approval.

* mm: consolidate init_mm definitionAlexey Dobriyan2009-06-161-4/+0
| | | | | | | | | | | | | | | | | | | * create mm/init-mm.c, move init_mm there * remove INIT_MM, initialize init_mm with C99 initializer * unexport init_mm on all arches: init_mm is already unexported on x86. One strange place is some OMAP driver (drivers/video/omap/) which won't build modular, but it's already wants get_vm_area() export. Somebody should look there.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current asm-generic/page.h only contains the get_order function, and asm-generic/uaccess.h only implements unaligned accesses. This renames the file to getorder.h and uaccess-unaligned.h to make room for new page.h and uaccess.h file that will be usable by all simple (e.g. nommu) architectures.

We cannot use CONFIG_64BIT for this in headers that are included from user space because CONFIG symbols are not available there. We also cannot do it inside of asm/types.h because some headers need the word size but cannot include types.h. The solution is to introduce a new header <asm/bitsperlong.h> that defines both __BITS_PER_LONG for user space and BITS_PER_LONG for usage in the kernel. The asm-generic version falls back to 32 bit unless the architecture overrides it, which I did for all 64 bit platforms.
