      Enable UAC transition from ApacheMonitor running as a vanilla user without priv · ef694f31
      William A. Rowe Jr authored 
      into a copy runas administrator with permissions (closing the original monitor),
in response to any start/stop/restart request who's control permissions failed.
This happens to work on Win2000 and later, although it is actually needed in 
Win2008 or Vista and later, where by default under UAC, the admin user actually 
has no permissions to control services unless the app is run elevated.  

We don't want to do this at start time, and assault the user with auth attempts
at login before they have even asked to use the features of the Monitor.  Once
we've made the transition, we'll leave the new monitor running elevated.  Some
branding with the "security" shield icon is actually recommended by the CUA, but
I'm neglecting this for the moment.

This patch drops the single instance mutex for a search of existing windows of 
our window's class & title, which is localized to the current session and just fine
for the purpose of restricting multiple invocations.

      Session cache interface redesign, Part 7: · 19c810a4
      Joe Orton authored 
      Clean up provider interface, removing use of mod_ssl-specific types:

* modules/ssl/ssl_private.h (modssl_sesscache_provider): Replace BOOL
  with apr_status_t, UCHAR with unsigned char; use 'unsigned int' for
  idlen; constify id arguments; remove pool argument from ->status.

* modules/ssl/ssl_scache_dc.c, modules/ssl/ssl_scache_memcache,
  modules/ssl/ssl_scache_shmcb.c, modules/ssl_scache_dbm.c: Update
  accordingly.

* modules/ssl/ssl_scache.c (ssl_scache_retrieve, ssl_scache_store):
  Adjust for BOOL->apr_status_t change.
  (ssl_ext_status_hook): Update for dropped pool argument.

      Joe Orton authored 
      Move provider-private context out of SSLModConfigRec and into an
opaque context pointer.  Use real error propagation in the ->init
functions rather than ssl_die().

* modules/ssl/ssl_private.h (modssl_sesscache_provider): Take a
  context out-parameter from ->init, and return an apr_status_t.
  Add context pointer as first arg for the other function types.
  (SSLModConfigRec): Remove tSessionCacheData* fields; add
  sesscache_context field.

* modules/ssl/ssl_scache.c (ssl_scache_init): Move once-per-process
  invocation check back into here.  
  (ssl_scache_*): Adjust to use context pointer.

* modules/ssl/ssl_scache_shmcb.c, modules/ssl/ssl_scache_dc.c,
  modules/ssl/ssl_scache_dbm.c: Adjust all implementations to use
  opaque context pointer.

* modules/ssl/ssl_scache_memcache.c: Move memcache context into the
  context structure rather than using global state.

* modules/ssl/ssl_engine_config.c: Remove handling of
  pSessionCacheData* fields in SSLModConfigRec.

      Move SSL session data deserialization up out of the session cache · c55b84c7
      Joe Orton authored 
      storage providers; includes a significant change to the shmcb storage
structure:

* modules/ssl/ssl_private.h (modssl_sesscache_provider): Change
  retrieve function to take dest/destlen output buffer, to take a
  constant id paramater, and to return a BOOL.

* modules/ssl/ssl_scache.c (ssl_scache_retrieve): Update accordingly,
  perform SSL deserialization here.

* modules/ssl/ssl_scache_dc.c (ssl_scache_dc_retrieve),
  modules/ssl/ssl_scache_dbm.c (ssl_scache_dbm_retrieve),
  modules/ssl/ssl_scache_memcache.c (ssl_scache_mc_retrieve):
  Update accordingly.

* modules/ssl/ssl_scache_shmcb.c: Store the whole ID in the cache
  before the data, so that each index can be compared against the
  requested ID without deserializing the data.  This requires approx
  20% extra storage per session in the common case, though should
  reduce CPU overhead in some retrieval paths.
  (SHMCBIndex): Replace s_id2 field with id_len.
  (shmcb_cyclic_memcmp): New function.
  (ssl_scache_shmcb_init): Change the heuristics to allow for increase
  in per-session storage requirement.
  (ssl_scache_shmcb_retrieve): Drop requirement on ID length.
  (shmcb_subcache_store): Store the ID in the cyclic buffer.
  (shmcb_subcache_retrieve, shmcb_subcache_remove): Compare against
  the stored ID rather than deserializing the data.
  (ssl_scache_shmcb_retrieve, ssl_scache_shmcb_store): Update
  accordingly.
