      9p: write lock path in v9fs_co_open2() · 5b76ef50
      由 Greg Kurz 提交于 
      The assumption that the fid cannot be used by any other operation is
wrong. At least, nothing prevents a misbehaving client to create a
file with a given fid, and to pass this fid to some other operation
at the same time (ie, without waiting for the response to the creation
request). The call to v9fs_path_copy() performed by the worker thread
after the file was created can race with any access to the fid path
performed by some other thread. This causes use-after-free issues that
can be detected by ASAN with a custom 9p client.

Unlike other operations that only read the fid path, v9fs_co_open2()
does modify it. It should hence take the write lock.

      A Single RISC-V Patch for 3.1-rc1

This tag contains a single patch that I'd like to target for rc1: a fix
for a memory leak that was detected by static code analysis.

There are still three patch sets that I'd like to try to get up for 3.1:

* The patch set Basian just published that contains fixes for a pair of
  issues he found when converting our port to decodetree.
* An as-of-yet-unwritten fix to the third issue that Basian pointed out.
* A fix to our fflags bug, which is currently coupled to some CSR
  refactoring that I don't think is OK for 3.1.

I'm at Plumbers next week (and I think Alistair is there too?), but I'll
try to find a way to squeeze in as much as possible.

that we free the memory but also updates the allocation to use
g_strdup_printf() instead of malloc().

      replay: Exit on errors reading from replay log · 0b570077
      由 Peter Maydell 提交于 
      Currently replay_get_byte() does not check for an error
from getc(). Coverity points out (CID 1390622) that this
could result in unexpected behaviour (such as looping
forever, if we use the replay_get_dword() return value
for a loop count). We don't expect reads from the replay
log to fail, and if they do there is no way we can
continue. So make them fatal errors.

      Add the spapr cap SPAPR_CAP_NESTED_KVM_HV to be used to control the
availability of nested kvm-hv to the level 1 (L1) guest.

Assuming a hypervisor with support enabled an L1 guest can be allowed to
use the kvm-hv module (and thus run it's own kvm-hv guests) by setting:
-machine pseries,cap-nested-hv=true
or disabled with:
-machine pseries,cap-nested-hv=false

      target/ppc: Add one reg id for ptcr · 56de52ca
      由 Suraj Jitindar Singh 提交于 
      The ptcr (partition table control register) is used to store the address
and size of the partition table. For nested kvm-hv we have a level 1
guest register the location of it's partition table with the hypervisor.
Thus to support migration we need to be able to read this out of kvm
and restore it post migration.

Add the one reg id for the ptcr.

      hw/ppc/ppc440_uc: Remove dead code in sdram_size() · 09a333ee
      由 Peter Maydell 提交于 
      Coverity points out in CID 1390588 that the test for sh == 0
in sdram_size() can never fire, because we calculate sh with
    sh = 1024 - ((bcr >> 6) & 0x3ff);
which must result in a value between 1 and 1024 inclusive.

Without the relevant manual for the SoC, we're not completely
sure of the correct behaviour here, but we can remove the
dead code without changing how QEMU currently behaves.
