![]() ![]() The parallelization in SecStaticCode::validateResources() checks the disk type (SSD versus non-SSD), so reproduction may depend on the media type on which the host app is stored. ![]() This does not occur in all configurations, but on configurations where it happens, it happens reliably. Attempt to create an OmniPlan document sync on that DAV server. OmniPlan for Mac offers more features (7) to their users than Team Foundation Server (3). That mutex is a recursive mutex, and the comment above it on line 130 suggests that Apple made it recursive to deal with this *exact* situation, but that broke when they inserted a dispatch_group.ģ. You can see this in Apple's published source code: see, and the first line of SecTrustSettingsEvaluateCert() is "StLock _(sutCacheLock())" (a RAII-style mutex acquisition). So the app deadlocks when the second thread tries to take out that same mutex. ![]() Problem: The first thing SecTrustSettingsEvaluateCert() does is take out a lock on a mutex. (So the main thread is blocked in dispatch_wait() via the Security::Dispatch::Group helper class.) That other thread does some stuff and eventually needs to evaluate a SecTrust, so it calls SecTrustEvaluate(), which eventually calls down to SecTrustSettingsEvaluateCert(). It's the same account that users may previously have had to make use of Omni's own sync server for OmniPlan or the company's other apps, so some. See Approved scanning vendors (ASVs) OpenProj, planning software, 271 Open-source Apache web server. Instead, you create an account on Omni's servers. It does that by dispatching to another thread. OmniPlan, planning software, 271 On-site assessors. The application calls SecTrustEvaluate(), which somewhere along the way calls SecTrustSettingsEvaluateCert(), which (for some reason?) wants to evaluate the app's code signing. OMNIPLAN is home to the most dedicated architects and professionals youll ever meet. However, it is also possible to see the bug by inspecting the released Apple source code (e.g. I've attached sampler excerpt showing the situation. amework will deadlock on a mutex in SecTrustSettingsEvaluateCert() when an application calls SecTrustEvaluate(). ![]()
