      Evgeniy Polyakov authored
      This is a driver for HIFN 795x crypto accelerator chips.
      
      It passed all tests for AES, DES and DES3_EDE except weak test for DES,
      since hardware can not determine weak keys.

      [CRYPTO] ctr: Add CTR (Counter) block cipher mode · 23e353c8
      Joy Latten authored
      This patch implements CTR mode for IPsec.
      It is based off of RFC 3686.
      
      Please note:
      1. CTR turns a block cipher into a stream cipher.
      Encryption is done in blocks, however the last block
      may be a partial block.
      
      A "counter block" is encrypted, creating a keystream
      that is xor'ed with the plaintext. The counter portion
      of the counter block is incremented after each block
      of plaintext is encrypted.
      Decryption is performed in same manner.
      
      2. The CTR counterblock is composed of,
              nonce + IV + counter
      
      The size of the counterblock is equivalent to the
      blocksize of the cipher.
              sizeof(nonce) + sizeof(IV) + sizeof(counter) = blocksize
      
      The CTR template requires the name of the cipher
      algorithm, the sizeof the nonce, and the sizeof the iv.
              ctr(cipher,sizeof_nonce,sizeof_iv)
      
      So for example,
              ctr(aes,4,8)
      specifies the counterblock will be composed of 4 bytes
      from a nonce, 8 bytes from the iv, and 4 bytes for counter
      since aes has a blocksize of 16 bytes.
      
      3. The counter portion of the counter block is stored
      in big endian for conformance to rfc 3686.

      [CRYPTO] padlock: Fix alignment fault in aes_crypt_copy · 490fe3f0
      Herbert Xu authored
      The previous patch fixed spurious read faults from occuring by copying
      the data if we happen to have a single block at the end of a page.  It
      appears that gcc cannot guarantee 16-byte alignment in the kernel with
      __attribute__.  The following report from Torben Viets shows a buffer
      that's only 8-byte aligned:
      
      > eneral protection fault: 0000 [#1]
      > Modules linked in: xt_TCPMSS xt_tcpmss iptable_mangle ipt_MASQUERADE
      > xt_tcpudp xt_mark xt_state iptable_nat nf_nat nf_conntrack_ipv4
      > iptable_filter ip_tables x_tables pppoe pppox af_packet ppp_generic slhc

      > CPU:    0
      > EIP:    0060:[<c035b828>]    Not tainted VLI
      > EFLAGS: 00010292   (2.6.23.12 #7)
      > EIP is at aes_crypt_copy+0x28/0x40
      > eax: f7639ff0   ebx: f6c24050   ecx: 00000001   edx: f6c24030
      > esi: f7e89dc8   edi: f7639ff0   ebp: 00010000   esp: f7e89dc8
      
      Since the hardware must have 16-byte alignment, the following patch fixes
      this by open coding the alignment adjustment.

      x86: simplify "make ARCH=x86" and fix kconfig all.config · 6840999b
      Sam Ravnborg authored
      Simplify "make ARCH=x86" and fix kconfig so we again can set 64BIT in
      all.config.
      
      For a fix the diffstat is nice:
       6 files changed, 3 insertions(+), 36 deletions(-)
      
      The patch reverts these commits:
       - 0f855aa6 ("kconfig: add helper to set
         config symbol from environment variable")
       - 2a113281 ("kconfig: use $K64BIT to
         set 64BIT with all*config targets")
      
      Roman Zippel pointed out that kconfig supported string compares so
      the additional complexity introduced by the above two patches were
      not needed.
      
      With this patch we have following behaviour:
      
        # make {allno,allyes,allmod,rand}config [ARCH=...]
        option \ host arch      | 32bit         | 64bit
        =====================================================
        ./.                     | 32bit         | 64bit
        ARCH=x86                | 32bit         | 32bit
        ARCH=i386               | 32bit         | 32bit
        ARCH=x86_64             | 64bit         | 64bit
      
      The general rule are that ARCH= and native architecture takes
      precedence over the configuration.
      
      So make ARCH=i386 [whatever] will always build a 32-bit kernel
      no matter what the configuration says.  The configuration will
      be updated to 32-bit if it was configured to 64-bit and the
      other way around.
      
      This behaviour is consistent with previous behaviour so no
      suprises here.
      
      make ARCH=x86 will per default result in a 32-bit kernel but as
      the only ARCH= value x86 allow the user to select between 32-bit
      and 64-bit using menuconfig.

      Truxton Fulton authored
      Attempt to fix http://bugzilla.kernel.org/show_bug.cgi?id=8378
      
      Hiroto Shibuya wrote to tell me that he has a VIA EPIA-EK10000 which
      suffers from the reboot problem when no keyboard is attached.  My first
      patch works for him:
      
        http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=59f4e7d572980a521b7bdba74ab71b21f5995538
      
      But the latest patch does not work for him :
      
        http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=8b93789808756bcc1e5c90c99f1b1ef52f839a51
      
      We found that it was necessary to also set the "disable keyboard" flag in
      the command byte, as the first patch was doing.  The second patch tries to
      minimally modify the command byte, but it is not enough.
      
      Please consider this simple one-line patch to help people with low end VIA
      motherboards reboot when no keyboard is attached.  Hiroto Shibuya has
      verified that this works for him (as I no longer have an afflicted
      machine).
      
      
      Additional discussion:
      
      Note that original patch from Truxton DOES
      disable keyboard and this has been in main tree since 2.6.14, thus it must have
      quite a bit of air time already.
      
      http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.14.y.git;a=commit;h=59f4e7d572980a521b7bdba74ab71b21f5995538
      
      Note that he only mention "System flag" in the description and comment, but
      in the code, "disable keyboard" flag is set.
      
        outb(0x14, 0x60);       /* set "System flag" */
      
      In 2.6.23, he made a change to read the current byte and then mask the flags,
      but along this change,  he only set the "System flag" and dropped the setting
      of "disable keyboard" flag.
      
      http://git.kernel.org/?p=linux/kernel/git/stable/linux-2.6.23.y.git;a=commit;h=8b93789808756bcc1e5c90c99f1b1ef52f839a51
      
         outb(cmd | 0x04, 0x60); /* set "System flag" */
      
      So my request is to restore the setting of disable keyboard flag which has been
      there since 2.6.14 but disappeared in 2.6.23.

      David P. Reed authored
      Correct potentially unstable PC RTC time register reading in time_64.c
      
      Stop the use of an incorrect technique for reading the standard PC RTC
      timer, which is documented to "disconnect" time registers from the bus
      while updates are in progress.  The use of UIP flag while interrupts
      are disabled to protect a 244 microsecond window is one of the
      Motorola spec sheet's documented ways to read the RTC time registers
      reliably.
      
      tglx: removed locking changes from original patch, as they gain nothing
      (read_persistent_clock is only called during boot, suspend, resume - so
      no hot path affected) and conflict with the paravirt locking scheme
      (see 32bit code), which we do not want to complicate for no benefit.

      Fix hard freeze on x86_64 when the ntpd service calls

      A repeatable but randomly timed freeze has been happening in Fedora 6
      and 7 for the last year, whenever I run the ntpd service on my AMD64x2
      HP Pavilion dv9000z laptop.  This freeze is due to the use of
      spin_lock(&rtc_lock) under the assumption (per a bad comment) that
      set_rtc_mmss is called only with interrupts disabled.  The call from
      ntp.c to update_persistent_clock is made with interrupts enabled.

      ntp: fix typo that makes sync_cmos_clock erratic · fa6a1a55
      David P. Reed authored
      Fix a typo in ntp.c that has caused updating of the persistent (RTC)
      clock when synced to NTP to behave erratically.
      
      When debugging a freeze that arises on my AMD64 machines when I
      run the ntpd service, I added a number of printk's to monitor the
      sync_cmos_clock procedure.  I discovered that it was not syncing to
      cmos RTC every 11 minutes as documented, but instead would keep trying
      every second for hours at a time.  The reason turned out to be a typo
      in sync_cmos_clock, where it attempts to ensure that
      update_persistent_clock is called very close to 500 msec. after a 1
      second boundary (required by the PC RTC's spec). That typo referred to
      "xtime" in one spot, rather than "now", which is derived from "xtime"
      but not equal to it.  This makes the test erratic, creating a
      "coin-flip" that decides when update_persistent_clock is called - when
      it is called, which is rarely, it may be at any time during the one
      second period, rather than close to 500 msec, so the value written is
      needlessly incorrect, too.

      x86: fix cpu-hotplug regression · 90367556
      Andreas Herrmann authored
      Commit d435d862
      ("cpu hotplug: mce: fix cpu hotplug error handling")
      changed the error handling in mce_cpu_callback.
      
      In cases where not all CPUs are brought up during
      boot (e.g. using maxcpus and additional_cpus parameters)
      mce_cpu_callback now returns NOTFIY_BAD because
      for such CPUs cpu_data is not completely filled when
      the notifier is called. Thus mce_create_device fails right
      at its beginning:
      
              if (!mce_available(&cpu_data[cpu]))
                      return -EIO;
      
      As a quick fix I suggest to check boot_cpu_data for MCE.
      
      To reproduce this regression:
      
      (1) boot with maxcpus=2 addtional_cpus=2 on a 4 CPU x86-64 system
      (2) # echo 1 >/sys/devices/system/cpu/cpu2/online
        -bash: echo: write error: Invalid argument
      
      dmesg shows:
      
      _cpu_up: attempt to bring up CPU 2 failed

      x86: ignore the sys_getcpu() tcache parameter · 4307d1e5
      Ingo Molnar authored
      dont use the vgetcpu tcache - it's causing problems with tasks
      migrating, they'll see the old cache up to a jiffy after the
      migration, further increasing the costs of the migration.
      
      In the worst case they see a complete bogus information from
      the tcache, when a sys_getcpu() call "invalidated" the cache
      info by incrementing the jiffies _and_ the cpuid info in the
      cache and the following vdso_getcpu() call happens after
      vdso_jiffies have been incremented.

      SELinux: return EOPNOTSUPP not ENOTSUPP · ec418781
      Eric Paris authored
      ENOTSUPP is not a valid error code in the kernel (it is defined in some
      NFS internal error codes and has been improperly used other places).  In
      the !CONFIG_SECURITY_SELINUX case though it is possible that we could
      return this from selinux_audit_rule_init().  This patch just returns the
      userspace valid EOPNOTSUPP.

      dirty page balancing: Get rid of broken unmapped_ratio logic · 8c086340
      Linus Torvalds authored
      This code harks back to the days when we didn't count dirty mapped
      pages, which led us to try to balance the number of dirty unmapped pages
      by how much unmapped memory there was in the system.
      
      That makes no sense any more, since now the dirty counts include the
      mapped pages.  Not to mention that the math doesn't work with HIGHMEM
      machines anyway, and causes the unmapped_ratio to potentially turn
      negative (which we do catch thanks to clamping it at a minimum value,
      but I mention that as an indication of how broken the code is).
      
      The code also was written at a time when the default dirty ratio was
      much larger, and the unmapped_ratio logic effectively capped that large
      dirty ratio a bit.  Again, we've since lowered the dirty ratio rather
      aggressively, further lessening the point of that code.
