Subject: [PATCH] nss: work around race condition in PK11_FindSlotByName()
|
||||
|
||||
Serialise the call to PK11_FindSlotByName() to avoid spurious errors in
|
||||
a multi-threaded environment. The underlying cause is a race condition
|
||||
in nssSlot_IsTokenPresent().
|
||||
|
||||
Bug: https://bugzilla.mozilla.org/1297397
|
||||
|
||||
Closes #985
