Version 2.1
+* Richard Henderson corrected size of struct timeval on Linux/Alpha to
+ conform to POSIX member type requirements. Symbol versions have been
+ adjusted as needed within the library, and for direct use by applications,
+ but there is potential for problems if third-party libraries use
+ struct timeval as part of their interface. This does not present
+ a problem for X and other "essential" system libraries.
+
* An additional locale model to support C++ Standard Library locale
model and probably more was implemented by Ulrich Drepper.

The ability to change the persona of a process can be a source of
unintentional privacy violations, or even intentional abuse. Because of
change to a particular user or group. This is the function of the setuid
and setgid bits of a file's access mode. @xref{Permission Bits}.
-When the setuid bit of an executable file is set, executing that file
-automatically changes the effective user ID to the user that owns the
-file. Likewise, executing a file whose setgid bit is set changes the
-effective group ID to the group of the file. @xref{Executing a File}.
-Creating a file that changes to a particular user or group ID thus
-requires full access to that user or group ID.
+When the setuid bit of an executable file is on, executing that file
+gives the process a third user ID: the @dfn{file user ID}. This ID is
+set to the owner ID of the file. The system then changes the effective
+user ID to the file user ID. The real user ID remains as it was.
+Likewise, if the setgid bit is on, the process is given a @dfn{file
+group ID} equal to the group ID of the file, and its effective group ID
+is changed to the file group ID.
+
+If a process has a file ID (user or group), then it can at any time
+change its effective ID to its real ID and back to its file ID.
+Programs use this feature to relinquish their special privileges except
+when they actually need them. This makes it less likely that they can
+be tricked into doing something inappropriate with their privileges.
+
+@strong{Portability Note:} Older systems do not have file IDs.
+To determine if a system has this feature, you can test the compiler
+define @code{_POSIX_SAVED_IDS}. (In the POSIX standard, file IDs are
+known as saved IDs.)
@xref{File Attributes}, for a more general discussion of file modes and
accessibility.
-A process can always change its effective user (or group) ID back to its
-real ID. Programs do this so as to turn off their special privileges
-when they are not needed, which makes for more robustness.
