Subject: [PATCH] Fix probing of C_GetInterface
|
|
|
|
`p11_dl_symbol (dl, "C_GetInterface")` uses dlsym() to find
|
|
C_GetInterface in the loaded pkcs11 module. For legacy (pre-3.0) pkcs11
|
|
modules, C_GetInterface is not defined in the module. But according to
|
|
the documentation of dlsym():
|
|
|
|
The search performed by dlsym() is breadth first through the
|
|
dependency tree of these shared objects.
|
|
|
|
So if a pkcs11 module links to libp11-kit.so, the C_GetInterface
|
|
implementation in libp11-kit.so itself will be found. This
|
|
C_GetInterface will return the metadata of p11-kit-proxy.so, causing
|
|
"Refuse to load the p11-kit-proxy.so as a registered module".
|
|
|
|
To solve the issue, if p11_dl_symbol() returns the C_GetInterface in
|
|
libp11-kit.so itself, we should ignore it and continue trying
|
|
C_GetFunctionList.
