New Revision: 44163
URL: http://svn.reactos.org/svn/reactos?rev=44163&view=rev
Log:
- Use a spin lock to protect OSKit instead of a recursive mutex
- Remove the now unused recursive mutex code
- Don't clear the SS_ISCONNECTING flag when soconnect returns EINPROGRESS because it
causes a crash during soreceive
- Lock CONNECTION_ENDPOINT and ADDRESS_FILE structs better
- Remove incorrect IoMarkIrpPending calls
- Remove useless ASSERT_LOCKED
- Don't destroy so_connection when we close a connection
- Remove useless FileFindConnectionByContext
- Remove SignalledConnectionsList and SignalledConnectionsLock and simply loop through
ConnectionEndpointList for signalled connections
- Add connections to ConnectionEndpointList in TCPAllocateConnectionEndpoint instead of
FileOpenConnection so we don't miss listeners
- Remove connections from ConnectionEndpointList in TCPFreeConnectionEndpoint instead of
FileCloseConnection so we don't miss listeners
- Use ExInterlockedRemoveHeadList to remove entries in the address file's request
lists
- Remove useless members, flags, and variables in titypes.h and tcp.h
- Fixes bug 4955 and 4434
