2012-10-21tpm: Propagate error from tpm_transmit to fix a timeout hangPeter Huewe
commit abce9ac292e13da367bbd22c1f7669f988d931ac upstream. tpm_write calls tpm_transmit without checking the return value and assigns the return value unconditionally to chip->pending_data, even if it's an error value. This causes three bugs. So if we write to /dev/tpm0 with a tpm_param_size bigger than TPM_BUFSIZE=0x1000 (e.g. 0x100a) and a bufsize also bigger than TPM_BUFSIZE (e.g. 0x100a) tpm_transmit returns -E2BIG which is assigned to chip->pending_data as -7, but tpm_write returns that TPM_BUFSIZE bytes have been successfully been written to the TPM, altough this is not true (bug #1). As we did write more than than TPM_BUFSIZE bytes but tpm_write reports that only TPM_BUFSIZE bytes have been written the vfs tries to write the remaining bytes (in this case 10 bytes) to the tpm device driver via tpm_write which then blocks at /* cannot perform a write until the read has cleared either via tpm_read or a user_read_timer timeout */ while (atomic_read(&chip->data_pending) != 0) msleep(TPM_TIMEOUT); for 60 seconds, since data_pending is -7 and nobody is able to read it (since tpm_read luckily checks if data_pending is greater than 0) (#bug 2). After that the remaining bytes are written to the TPM which are interpreted by the tpm as a normal command. (bug #3) So if the last bytes of the command stream happen to be a e.g. tpm_force_clear this gets accidentally sent to the TPM. This patch fixes all three bugs, by propagating the error code of tpm_write and returning -E2BIG if the input buffer is too big, since the response from the tpm for a truncated value is bogus anyway. Moreover it returns -EBUSY to userspace if there is a response ready to be read.

2012-08-15random: mix in architectural randomness in extract_buf()H. Peter Anvin
commit d2e7c96af1e54b507ae2a6a7dd2baf588417a7e5 upstream. Mix in any architectural randomness in extract_buf() instead of xfer_secondary_buf(). This allows us to mix in more architectural randomness, and it also makes xfer_secondary_buf() faster, moving a tiny bit of additional CPU overhead to process which is extracting the randomness.

2012-08-15random: Add comment to random_initialize()Tony Luck
commit cbc96b7594b5691d61eba2db8b2ea723645be9ca upstream. Many platforms have per-machine instance data (serial numbers, asset tags, etc.) squirreled away in areas that are accessed during early system bringup. Mixing this data into the random pools has a very high value in providing better random data, so we should allow (and even encourage) architecture code to call add_device_randomness() from the setup_arch() paths. However, this limits our options for internal structure of the random driver since random_initialize() is not called until long after setup_arch(). Add a big fat comment to rand_initialize() spelling out this requirement.

2012-08-15random: add new get_random_bytes_arch() functionTheodore Ts'o
commit c2557a303ab6712bb6e09447df828c557c710ac9 upstream. Create a new function, get_random_bytes_arch() which will use the architecture-specific hardware random number generator if it is present. Change get_random_bytes() to not use the HW RNG, even if it is avaiable. The reason for this is that the hw random number generator is fast (if it is present), but it requires that we trust the hardware manufacturer to have not put in a back door. (For example, an increasing counter encrypted by an AES key known to the NSA.) It's unlikely that Intel (for example) was paid off by the US Government to do this, but it's impossible for them to prove otherwise --- especially since Bull Mountain is documented to use AES as a whitener. Hence, the output of an evil, trojan-horse version of RDRAND is statistically indistinguishable from an RDRAND implemented to the specifications claimed by Intel. Short of using a tunnelling electronic microscope to reverse engineer an Ivy Bridge chip and disassembling and analyzing the CPU microcode, there's no way for us to tell for sure. Since users of get_random_bytes() in the Linux kernel need to be able to support hardware systems where the HW RNG is not present, most time-sensitive users of this interface have already created their own cryptographic RNG interface which uses get_random_bytes() as a seed. So it's much better to use the HW RNG to improve the existing random number generator, by mixing in any entropy returned by the HW RNG into /dev/random's entropy pool, but to always _use_ /dev/random's entropy pool. This way we get almost of the benefits of the HW RNG without any potential liabilities. The only benefits we forgo is the speed/performance enhancements --- and generic kernel code can't depend on depend on get_random_bytes() having the speed of a HW RNG anyway. For those places that really want access to the arch-specific HW RNG, if it is available, we provide get_random_bytes_arch().

2012-08-15random: use the arch-specific rng in xfer_secondary_poolTheodore Ts'o
commit e6d4947b12e8ad947add1032dd754803c6004824 upstream. If the CPU supports a hardware random number generator, use it in xfer_secondary_pool(), where it will significantly improve things and where we can afford it. Also, remove the use of the arch-specific rng in add_timer_randomness(), since the call is significantly slower than get_cycles(), and we're much better off using it in xfer_secondary_pool() anyway.

2012-08-15random: create add_device_randomness() interfaceLinus Torvalds
commit a2080a67abe9e314f9e9c2cc3a4a176e8a8f8793 upstream. Add a new interface, add_device_randomness() for adding data to the random pool that is likely to differ between two devices (or possibly even per boot). This would be things like MAC addresses or serial numbers, or the read-out of the RTC. This does *not* add any actual entropy to the pool, but it initializes the pool to different values for devices that might otherwise be identical and have very little entropy available to them (particularly common in the embedded world).

2012-08-15random: make 'add_interrupt_randomness()' do something saneTheodore Ts'o
commit 775f4b297b780601e61787b766f306ed3e1d23eb upstream. We've been moving away from add_interrupt_randomness() for various reasons: it's too expensive to do on every interrupt, and flooding the CPU with interrupts could theoretically cause bogus floods of entropy from a somewhat externally controllable source. This solves both problems by limiting the actual randomness addition to just once a second or after 64 interrupts, whicever comes first. During that time, the interrupt cycle data is buffered up in a per-cpu pool. Also, we make sure the the nonblocking pool used by urandom is initialized before we start feeding the normal input pool. This assures that /dev/urandom is returning unpredictable data as soon as possible. (Based on an original patch by Linus, but significantly modified by tytso.)

2012-08-15Redefine ATOMIC_INIT and ATOMIC64_INIT to drop the castsTony Luck
commit a119365586b0130dfea06457f584953e0ff6481d upstream. The following build error occured during a ia64 build with swap-over-NFS patches applied. net/core/sock.c:274:36: error: initializer element is not constant net/core/sock.c:274:36: error: (near initialization for 'memalloc_socks') net/core/sock.c:274:36: error: initializer element is not constant This is identical to a parisc build error. Fengguang Wu, Mel Gorman and James Bottomley did all the legwork to track the root cause of the problem. This fix and entire commit log is shamelessly copied from them with one extra detail to change a dubious runtime use of ATOMIC_INIT() to atomic_set() in drivers/char/mspec.c Dave Anglin says: > Here is the line in sock.i: > > struct static_key memalloc_socks = ((struct static_key) { .enabled = > ((atomic_t) { (0) }) }); The above line contains two compound literals. It also uses a designated initializer to initialize the field enabled. A compound literal is not a constant expression. The location of the above statement isn't fully clear, but if a compound literal occurs outside the body of a function, the initializer list must consist of constant expressions.

2012-08-09TPM: chip disabled state erronously being reported as errorRajiv Andrade
commit 24ebe6670de3d1f0dca11c9eb372134c7ab05503 upstream. tpm_do_selftest() attempts to read a PCR in order to decide if one can rely on the TPM being used or not. The function that's used by __tpm_pcr_read() does not expect the TPM to be disabled or deactivated, and if so, reports an error. It's fine if the TPM returns this error when trying to use it for the first time after a power cycle, but it's definitely not if it already returned success for a previous attempt to read one of its PCRs. The tpm_do_selftest() was modified so that the driver only reports this return code as an error when it really is.

2012-04-05simple_open: automatically convert to simple_open()Stephen Boyd
Many users of debugfs copy the implementation of default_open() when they want to support a custom read/write function op. This leads to a proliferation of the default_open() implementation across the entire tree. Now that the common implementation has been consolidated into libfs we can replace all the users of this function with simple_open(). This replacement was done with the following semantic patch: <smpl> @ open @ identifier open_f != simple_open; identifier i, f; @@ -int open_f(struct inode *i, struct file *f) -{ ( -if (i->i_private) -f->private_data = i->i_private; | -f->private_data = i->i_private; ) -return 0; -} @ has_open depends on open @ identifier fops; identifier open.open_f; @@ struct file_operations fops = { ... -.open = open_f, +.open = simple_open, ... }; </smpl> [akpm@linux-foundation.org: checkpatch fixes] Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Al Viro <viro@zeniv.linux.org.uk> Cc: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2012-04-03APM: fix deadlock in APM_IOC_SUSPEND ioctlNeilBrown
I found the Xorg server on my ARM device stuck in the 'msleep()' loop in apm_ioctl. I suspect it had attempted suspend immediately after resuming and lost a race. During that msleep(10);, a new suspend cycle must have started and changed ->suspend_state to SUSPEND_PENDING, so it was never seen to be SUSPEND_DONE and the loop could never exited. It would have moved on to SUSPEND_ACKTO but never been able to reach SUSPEND_DONE. So change the loop to only run while SUSPEND_ACKED rather than until SUSPEND_DONE. This is much safer.

2012-03-28ipmi: use locks on watchdog timeout set on rebootCorey Minyard
The IPMI watchdog timer clears or extends the timer on reboot/shutdown. It was using the non-locking routine for setting the watchdog timer, but this was causing race conditions.

I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis."

It also contains some changes to the i2c tree which Jean has acked, and one change to moorestown platform stuff in x86. Highlights: - new drivers: UDL driver for USB displaylink devices, kms only, should support correct hotplug operations. - core: i2c speedups + better hotplug support, EDID overriding via firmware interface - allows user to load a firmware for a broken monitor/kvm from userspace, it even has documentation for it. - exynos: new HDMI audio + hdmi 1.4 + virtual output driver - gma500: code cleanup - radeon: cleanups, CS optimisations, streamout support and pageflip fix - nouveau: NVD9 displayport support + more reclocking work - i915: re-enabling GMBUS, finish gpu patch (might help hibernation who knows), missed irq fixes, stencil tiling fixes, interlaced support, aliasesd PPGTT support for SNB/IVB, swizzling for SNB/IVB, semaphore fixes As well as the usual bunch of cleanups and fixes all over the place. I've got two things I'd like to merge a bit later: a) AMD support for all their new radeonhd 7000 series GPU and APUs. AMD dropped this a bit late due to insane internal review processes, (please AMD just follow Intel and let open source guys ship stuff early) however I don't want to penalise people who own this hardware (since its been on sale for 3-4 months and GPU hw doesn't exactly have a lifetime in years) and consign them to using closed drivers for longer than necessary. The changes are well contained and just plug into the driver new gpu functionality so they should be fairly regression proof. I just want to give them a bit of a run on the hw AMD kindly sent me. b) drm prime/dma-buf interface code. This is just infrastructure code to expose the dma-buf stuff to drm drivers and to userspace. I'm not planning on pushing any driver support in this cycle (except maybe exynos), but I'd like to get the infrastructure code in so for the next cycle I can start getting the driver support into the individual drivers. We have started driver support for i915, nouveau and udl along with I think exynos and omap in staging. However this code relies on the dma-buf tree being pulled into your tree first since it needs the latest interfaces from that tree. I'll push to get that tree sent asap.

There's still some bits and pieces remaining if you do a grep -ir series arch/powerpc but they are harmless and will be removed in the next few weeks hopefully. - The 'fadump' functionality (Firmware Assisted Dump) replaces the previous (equivalent) "pHyp assisted dump"... it's a rewrite of a mechanism to get the hypervisor to do crash dumps on pSeries, the new implementation hopefully being much more reliable.

2012-03-16ARM: 7362/1: AMBA: Add module_amba_driver() helper macro for amba_driverviresh kumar
For simple modules that contain a single amba_driver without any additional setup code then ends up being a block of duplicated boilerplate. This patch adds a new macro, module_amba_driver(), which replaces the module_init()/module_exit() registrations with template functions.
