minor Hivex.xs leaks
Hi Rich,
While I was looking at hivex today I ran coverity on it.
It spotted one problem but missed a similar one nearby.
The following are from Hivex.xs: (generated by generator.ml)
void
node_set_values (h, node, values)
hive_h *h;
int node;
pl_set_values values = unpack_pl_set_values (ST(2));
PREINIT:
int r;
PPCODE:
r = hivex_node_set_values (h, node, values.nr_values, values.values, 0);
free (values.values);
if (r == -1)
croak ("%s: %s", "node_set_values", strerror (errno));
void
node_set_value (h, node, val)

[hivex] Segfault for an integer value to node_set_value
Hi,
When an integer argument is passed as value, node_set_value
segfaults. Reproducer is at the end of this message
The backtrace points at hivex-py.c, function get_value. While obj
is non-NULL, `bytes = PyUnicode_AsUTF8String (obj);` returns NULL.
Kind regards,
Peter

[hivex] [PATCH 0/6] Python fixes for node_set_value
Hi,
This patch series is based on a prior patch[1], splitting off changes as
requested and incorporating feedback from Richard Jones. It introduces type
validation to avoid segmentation faults (instead, it reports an exception) and
fixes handling of the bytes type in Python 3.
Major changes since that series:
- Drop newly introduced support for integer types for DWORD/QWORDS
- Reject Unicode
