C_WaitForSlotEvent() missed during PIN entry (C_OpenSession())

[dirkx]

It seems that once C_OpenSession() is entered; the physical removal is not noted in the C_WaitForSlotEvent() (polling) loop.

So code like

  C_OpenSession
  if (PIN needed)
       ask for pin
  ...
  C_Login()

with a separate polling thread on C_WaitForSlotEvent() will not note the removal during that ask-pin period (but will do post C_Login()).

A work around is

  C_OpenSession
  if (PIN needed)
       C_CloseSession)
       ask for pin
       C_OpenSession
  ...
  C_Login()

but this does not help firefox/mozilla and the keychain tokend adaptor. The result is a hang in firefox.

does the problem still occur with the newest version of opensc?

Could you provide a debug log of OpenSC?

Which version of Firefox is affected?

please reopen the issue when new information is available or if you know how to solve the problem inside of OpenSC
