Coming back to reading after holidays

Comments in italics are mine and express my own views, thoughts and opinions

Windows Internals by M. Russinovich, D. Solomon and A. Ionescu:

Per session objects \Sessions\n\BaseNamedObjects (p. 158)

OpenXXX / CreateXXX race condition: solution CreateXXXEx (p. 159)

Most objects are temporary (p. 159) - I got an idea for a bugtation “Most bugs are permanent”

Name retention by handle access vs. reference retention by pointer access (pp. 159 - 160) - most objects have a few references but some are referenced a lot:

0: kd> !handle

[...]

002c: Object: fffffa80047db0d0  GrantedAccess: 000f01ff Entry: fffff880078c70b0
Object: fffffa80047db0d0  Type: (fffffa8003c0bdc0) Desktop
    ObjectHeader: fffffa80047db0a0 (old version)
        HandleCount: 61  PointerCount: 7534
        Directory Object: 00000000  Name: Default

[...]

Deferred object delete operation (p. 160)

Resource accounting (pp. 161 - 162) - it would be nice to have an example here using object header structures

Name squatting (p. 164)

Private namespaces in Vista, CreatePrivateNamespace for user apps, solution to name squatting attacks (p. 164)

CheckForOtherInstanceMutex (p. 166) - Windows API legacy: search for a window with the same class can be used for single instancing

Sound Mixer in Vista/W2k8 (p. 166) - this is the great feature I didn’t know about
