      drivers/gicv3: fix potential GICD context override with ESPI enabled · deb18901
      Heyi Guo authored 
      

RESTORE/SAVE_GICD_EREGS uses (int_id - (MIN_ESPI_ID - MIN_SPI_ID)) to
get the context array index for ESPI, which will override the space of
standard SPI starting from (MIN_SPI_ID + MIN_SPI_ID).

However, using TOTAL_SPI_INTR_NUM to replace the above MIN_SPI_ID
cannot totally fix the issue, for TOTAL_SPI_INTR_NUM is not well
aligned and the array index will be rounded down by the shifting
operation if being shifted more than 2 bits. It will cause buffer
override again when the existing maximum SPI reaches 1019.

So round up TOTAL_SPI_INTR_NUM with (1 << REG##R_SHIFT) for GICD
context arrays.

      drivers/gicv3: use mpidr to probe GICR for current CPU · 60cd8030
      Heyi Guo authored 
      

In function gicv3_rdistif_probe(), line #1322 implies
gicv3_driver_data->mpidr_to_core_pos() may be null, but the original
code uses this interface to get current CPU index unconditionally.

It is better to use MPIDR to probe GICR which does not depend on
gicv3_driver_data->mpidr_to_core_pos().

      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.
