Detect whether a key is an sm2 type of key by its OID in the parameters
array rather than assuming that everything under OID_id_ecPublicKey
is sm2, which is not the case.

Callers of sprint_oid() do not check its return value before printing
the result. In the case where the OID is zero-length, -EBADMSG was
being returned without anything being written to the buffer, resulting
in uninitialized stack memory being printed. Fix this by writing
"(bad)" to the buffer in the cases where -EBADMSG is returned.

In sprint_oid(), if the input buffer were to be more than 1 byte too
small for the first snprintf(), 'bufsize' would underflow, causing a
buffer overflow when printing the remainder of the OID.
Fortunately this cannot actually happen currently, because no users pass
in a buffer that can be too small for the first snprintf().
Regardless, fix it by checking the snprintf() return value correctly.
For consistency also tweak the second snprintf() check to look the same.

for OID string
The sprint_oid() utility function doesn't properly check the buffer size
that it causes that the warning in vsnprintf() be triggered. For
example on v4.1 kernel:
------------[ cut here ]------------
WARNING: CPU: 0 PID: 2357 at lib/vsprintf.c:1867 vsnprintf+0x5a7/0x5c0()
...
We can trigger this issue by injecting maliciously crafted x509 cert in
DER format. Just using hex editor to change the length of OID to over
the length of the SEQUENCE container. For example:
0:d=0 hl=4 l= 980 cons: SEQUENCE
4:d=1 hl=4 l= 700 cons: SEQUENCE
8:d=2 hl=2 l= 3 cons: cont [ 0 ]
10:d=3 hl=2 l= 1 prim: INTEGER :02
13:d=2 hl=2 l= 9 prim: INTEGER :9B47FAF791E7D1E3
24:d=2 hl=2 l= 13 cons: SEQUENCE
26:d=3 hl=2 l= 9 prim: OBJECT :sha256WithRSAEncryption
37:d=3 hl=2 l= 0 prim: NULL
39:d=2 hl=2 l= 121 cons: SEQUENCE
41:d=3 hl=2 l= 22 cons: SET
43:d=4 hl=2 l= 20 cons: SEQUENCE <=== the SEQ length is 20
45:d=5 hl=2 l= 3 prim: OBJECT :organizationName
<=== the original length is 3, change the length of OID to over the length of SEQUENCE
Pawel Wieczorkiewicz reported this problem and Takashi Iwai provided
patch to fix it by checking the bufsize in sprint_oid().

Add a pair of utility functions to render OIDs as strings. The first takes an
encoded OID and turns it into a "a.b.c.d" form string:
int sprint_oid(const void *data, size_t datasize,
char *buffer, size_t bufsize);
The second takes an OID enum index and calls the first on the data held
therein:
int sprint_OID(enum OID oid, char *buffer, size_t bufsize);

Implement a simple static OID registry that allows the mapping of an encoded
OID to an enum value for ease of use.
The OID registry index enum appears in the:
linux/oid_registry.h
header file. A script generates the registry from lines in the header file
that look like:
<sp*>OID_foo,<sp*>/*<sp*>1.2.3.4<sp*>*/
The actual OID is taken to be represented by the numbers with interpolated
dots in the comment.
All other lines in the header are ignored.
The registry is queries by calling:
OID look_up_oid(const void *data, size_t datasize);
This returns a number from the registry enum representing the OID if found or
OID__NR if not.
