      plat/arm: Always allow ARM_LINUX_KERNEL_AS_BL33 · c99b8c89
      Andre Przywara authored 
      

At the moment we have the somewhat artifical limitation of
ARM_LINUX_KERNEL_AS_BL33 only being used together with RESET_TO_BL31.

However there does not seem to be a good technical reason for that,
it was probably just to differentate between two different boot flows.

Move the initial register setup for ARM_LINUX_KERNEL_AS_BL33 out of the
RESET_TO_BL31 #ifdef, so that we initialise the registers in any case.

This allows to use a preloaded kernel image when using BL1 and FIP.

      fdts: Fix stdout-path in various platforms · fcb0ea19
      Nikos Nikoleris authored 
      

The value of stdout-path is a string and as a result, we can't use a
label as a reference to the serial0 node. This change fixes the
stdout-path property for N1SDP, Morello and TC0 by pointing to the
right alias.

      cert-tool: avoid duplicates in extension stack · 1ed941c0
      Jimmy Brisson authored 
      

This bug manifests itself as a segfault triggered by a double-free.

I noticed that right before the double-free, the sk list contained 2
elements with the same address.

    (gdb) p sk_X509_EXTENSION_value(sk, 1)
    $34 = (X509_EXTENSION *) 0x431ad0
    (gdb) p sk_X509_EXTENSION_value(sk, 0)
    $35 = (X509_EXTENSION *) 0x431ad0
    (gdb) p sk_X509_EXTENSION_num(sk)
    $36 = 2

This caused confusion; this should never happen.

I figured that this was caused by a ext_new_xxxx function freeing
something before it is added to the list, so I put a breakpoint on
each of them to step through. I was suprised to find that none of my
breakpoints triggered for the second element of the iteration through
the outer loop just before the double-free.

Looking through the code, I noticed that it's possible to avoid doing
a ext_new_xxxx, when either:
   * ext->type == NVCOUNTER and ext->arg == NULL
   * ext->type == HASH and ext->arg == NULL and ext->optional == false
So I put a breakpoint on both.

It turns out that it was the HASH version, but I added a fix for both.
The fix for the Hash case is simple, as it was a mistake. The fix for
the NVCOUNTER case, however, is a bit more subtle. The NVCOUNTER may
be optional, and when it's optional we can skip it. The other case,
when the NVCOUNTER is required (not optinal), the `check_cmd_params`
function has already verified that the `ext->arg` must be non-NULL.
We assert that before processing it to covert any possible segfaults
into more descriptive errors.

This should no longer cause double-frees by adding the same ext twice.

      tools: cert_create: Create only requested certificates · 294e2656
      Manish V Badarkhe authored 
      

The certification tool creates all the certificates mentioned
statically in the code rather than taking explicit certificate
requests from the command line parameters.

Code is optimized to avoid unnecessary attempts to create
non-requested certificates.

      allwinner: Leave CPU power alone during BL31 setup · ed267c92
      Samuel Holland authored 
      

Disabling secondary CPUs during boot is unnecessary because the other
CPUs are already in reset, and it saves an entirely insignificant amount
of power. Let's remove this bit of code that was added mostly "because
we can", and along with it remove an unconditional dependency on the CPU
ops functions.
