-+              The EGLIBC Component Configuration System
-+                  Jim Blandy <jimb@codesourcery.com>
-+
-+Introduction
-+
-+The GNU C library (GLIBC) provides a broad range of functionality,
-+ranging from internationalization support to transcendental
-+mathematical functions.  Its website boasts that "nearly all known and
-+useful functions from any other C library are available."  This
-+exhaustive approach has been one of GLIBC's strengths on desktop and
-+server systems, but it has also given GLIBC a large footprint, both in
-+memory and on disk, making it a challenge to use in embedded systems
-+with limited resources.
-+
-+The Embedded GNU C library (EGLIBC) is a variant of the GNU C library
-+designed to work well on embedded systems.  In particular, EGLIBC's
-+component configuration system allows embedded developers to build
-+customized versions of the library that include only the features
-+their application uses, reducing its space requirements.
-+
-+EGLIBC's component configuration system categorizes the library's
-+functions into "option groups", and allows you to include or exclude
-+option groups individually.  Some option groups depend on others;
-+EGLIBC tracks these relationships, and ensures that the selected
-+configuration yields a functioning library.
-+
-+
-+Consistent and Predictable Behavior
-+
-+A flexible configuration system is a mixed blessing: if the options
-+offered are poorly designed, it can be hard to see which choices will
-+have the desired effects, and choices with obscure consequences can
-+make debugging difficult.  EGLIBC's configuration follows some general
-+principles to reduce these risks:
-+
-+- EGLIBC has a single default configuration for each target
-+  architecture.
-+
-+- In the default configuration, all option groups are enabled, and
-+  EGLIBC is upwardly API- and ABI-compatible with GLIBC.
-+
-+- As much as possible, configurations only affect what functions are
-+  present, not how they behave.  If the system works with an option
-+  group disabled, it will still work with it enabled.
-+
-+- As much as possible, configurations only select option groups ---
-+  they do not describe characteristics of the target architecture.
-+
-+These rules mean that you have a simple debugging strategy available
-+if you suspect that your EGLIBC configuration might be the source of a
-+problem: fall back to the default configuration, re-test, and then
-+disable option groups one by one, until the problem reappears.
-+
-+
-+The Option Groups
-+
-+To see the current full list of implemented option groups, refer to the
-+file 'option-groups.def' at the top of the source tree, or run
-+'make menuconfig' from the top-level build directory.
-+
-+The POSIX.1-2001 specification includes a suggested partition of all
-+the functions in the POSIX C API into option groups: math functions
-+like 'sin' and 'cos'; networking functions like 'socket' and
-+'connect'; and so on.  EGLIBC could use this partitioning as the basis
-+for future option groups.
-+
-+
-+Implementation
-+
-+The EGLIBC component configuration system resembles the approach used
-+by the Linux kernel to select device drivers, network protocols, and
-+other features.  A file named 'option-groups.config' in the top-level
-+build directory contains assignments to Make variables, each of which
-+enables or disables a particular option group.  If the variable's
-+value is set to 'y', then the option group is enabled; if it set to
-+anything else, the option group is omitted.  The file
-+'option-groups.defaults', at the top of the source tree, establishes
-+default values for all variables; all option groups are enabled by
-+default.
-+
-+For example, the following 'option-groups.config' would omit locale
-+data, but include mathematical functions, and everything else:
-+
-+   OPTION_EGLIBC_LOCALES = n
-+   OPTION_EGLIBC_LIBM = y
-+
-+Like the Linux kernel, EGLIBC supports a similar set of '*config' make
-+targets to make it easier to create 'option-groups.config', with all
-+dependencies between option groups automatically satisfied.  Run
-+'make help' to see the list of supported make config targets.  For
-+example, 'make menuconfig' will update the current config utilising a
-+menu based program.
-+
-+The option group names and their type (boolean, int, hex, string), help
-+description, and dependencies with other option groups, are described by
-+'option-groups.def' at the top of the source tree, analogous to the
-+'Kconfig' files in the Linux kernel.
-+
-+In general, each option group variable controls whether a given set of
-+object files in EGLIBC is compiled and included in the final
-+libraries, or omitted from the build.
-+
-+Each subdirectory's Makefile categorizes its routines, libraries, and
-+executables by option group.  For example, EGLIBC's 'math/Makefile'
-+places the 'libm' library in the OPTION_EGLIBC_LIBM group as follows:
-+
-+   extra-libs-$(OPTION_EGLIBC_LIBM) := libm
-+
-+Finally, common code in 'Makerules' cites the value of the variable
-+'extra-libs-y', selecting only those libraries that belong to enabled
-+option groups to be built.
-+
-+
-+Current Status and Future Directions
-+
-+The EGLIBC component configuration system described here is still
-+under development.
-+
-+We have used the system to subset some portions of EGLIBC's

-+          time.
-+
-+          This should be an absolute filename.  The EGLIBC build

-+
-+          In this arrangement, EGLIBC will not use the 'dlopen' and

-+        some of these functions; you will not be able to link or run
-+        C++ programs if you disable this option group.
-+
-+        This option group also affects the behavior of the following

-+          fopen64
-+          freopen

-+
-+        These functions all take an OPENTYPE parameter which may
-+        contain a string of the form ",ccs=CHARSET", indicating that
-+        the underlying file uses the character set named CHARSET.
-+        This produces a wide-oriented stream, which is only useful
-+        when the functions included in this option group are present.
-+        If the user attempts to open a file specifying a character set
-+        in the OPENTYPE parameter, and EGLIBC was built with this
-+        option group disabled, the function returns NULL, and sets
-+        errno to EINVAL.

-+/* When OPTION_EGLIBC_NSSWITCH is disabled (see option-groups.def),
-+   EGLIBC does not use the 'dlopen' and 'dlsym' functions to look for
-+   database query functions in the individual name service libraries.
-+   Instead, it uses a set of functions chosen at compile time, as
-+   directed by the OPTION_EGLIBC_NSSWITCH_FIXED_FUNCTIONS file.  This
-+   file is a sample of what you might use there.
-+
-+   This file is C source code; it should only contain invocations of
-+   the following macros:
-+
-+   - DEFINE_ENT (DATABASE, SERVICE, X)
-+
-+     Declare the 'setXent', 'getXent_r', and 'endXent' functions that
-+     query DATABASE using the service library 'libnss_SERVICE.so.2'.
-+     DATABASE should be the full name of the database as it appears in
-+     'nsswitch.conf', like 'passwd' or 'aliases'.
-+
-+     (The non-reentrant 'getXent' functions are implemented in terms
-+     of the reentrant 'getXent_r' functions, so there is no need to
-+     refer to them explicitly here.)
-+
-+   - DEFINE_GETBY (DATABASE, SERVICE, X, KEY)
-+
-+     Declare the 'getXbyKEY_r' functions that query DATABASE using
-+     SERVICE.  DATABASE and SERVICE are as described above.
-+

-Subject: [PATCH 27/27] eglibc-use-option-groups: Conditionally exclude c++
- tests
-
-    Some test programs written in c++ are still included in spite of
-    "libc-cxx-tests" being omitted from DISTRO_FEATURES_LIBC.
-    All .cc programs are compiled with g++.
-    g++ automatically specifies linking against the C++ library.
-    This patch conditionally excludes the following tests as well:
-
-      bug-atexit3-lib.cc
-      tst-cancel24.cc
-      tst-cancel24-static.cc
-      tst-unique3lib.cc
-      tst-unique3lib2.cc
-      tst-unique4lib.cc
-      tst-unique3.cc
-      tst-unique4.cc
-
-    Tested with DISTRO_FEATURES_LIBC_remove = " libc-cxx-tests"

-Subject: [PATCH] Keep only ELF_RTYPE_CLASS_{PLT|COPY} bits for prelink
-
-prelink runs ld.so with the environment variable LD_TRACE_PRELINKING
-set to dump the relocation type class from _dl_debug_bindings.  prelink
-has the following relocation type classes:
-
- #define RTYPE_CLASS_VALID       8
- #define RTYPE_CLASS_PLT         (8|1)
- #define RTYPE_CLASS_COPY        (8|2)
- #define RTYPE_CLASS_TLS         (8|4)
-
-where ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA has a conflict with
-RTYPE_CLASS_TLS.
-
-Since prelink only uses ELF_RTYPE_CLASS_PLT and ELF_RTYPE_CLASS_COPY
-bits, we should clear the other bits when the DL_DEBUG_PRELINK bit is
-set.
-
-        [BZ #19178]
-        * elf/dl-lookup.c (RTYPE_CLASS_VALID): New.
-        (RTYPE_CLASS_PLT): Likewise.
-        (RTYPE_CLASS_COPY): Likewise.
-        (RTYPE_CLASS_TLS): Likewise.
-        (_dl_debug_bindings): Use RTYPE_CLASS_TLS and RTYPE_CLASS_VALID
-        to set relocation type class for DL_DEBUG_PRELINK.  Keep only
-        ELF_RTYPE_CLASS_PLT and ELF_RTYPE_CLASS_COPY bits for
-        DL_DEBUG_PRELINK.

-Subject: [PATCH] getmntent: fix memory corruption w/blank lines [BZ #18887]
-
-The fix for BZ #17273 introduced a single byte of memory corruption when
-the line is entirely blank.  It would walk back past the start of the
-buffer if the heap happened to be 0x20 or 0x09 and then write a NUL byte.
-       buffer = '\n';
-       end_ptr = buffer;
-       while (end_ptr[-1] == ' ' || end_ptr[-1] == '\t')
-             end_ptr--;
-             *end_ptr = '\0';
-
-Fix that and rework the tests.  Adding the testcase for BZ #17273 to the
-existing \040 parser does not really make sense as it's unrelated, and
-leads to confusing behavior: it implicitly relies on the new entry being
-longer than the previous entry (since it just rewinds the FILE*).  Split
-it out into its own dedicated testcase instead.
-
-The original patch is at link https://sourceware.org/git/gitweb.cgi?p=glibc.git;a=patch;h=b0e805fa0d6fea33745952df7b7f5442ca4c374f.
-Only code to mntent_r.c is kept in this patch, Change log, NEWS, Makefile, and test cases are excluded.

-+     compromise and attention to symmetry (A or AAAA queries can be
-+     returned in any order).  What follows is a breakdown of how this
-+     code is expected to work and why. We discuss only SUCCESS,
-+     TRYAGAIN, NOTFOUND and UNAVAIL, since they are the only returns
-+     that apply (though RETURN and MERGE exist).  We make a distinction
-+     between TRYAGAIN (recoverable) and TRYAGAIN' (not-recoverable).
-+     A recoverable TRYAGAIN is almost always due to buffer size issues
-+     and returns ERANGE in errno and the caller is expected to retry
-+     with a larger buffer.
-+
-+     Lastly, you may be tempted to make significant changes to the
-+     conditions in this code to bring about symmetry between responses.
-+     Please don't change anything without due consideration for
-+     expected application behaviour.  Some of the synthesized responses
-+     aren't very well thought out and sometimes appear to imply that
-+     IPv4 responses are always answer 1, and IPv6 responses are always
-+     answer 2, but that's not true (see the implementation of send_dg
-+     and send_vc to see response can arrive in any order, particularly
-+     for UDP). However, we expect it holds roughly enough of the time
-+     that this code works, but certainly needs to be fixed to make this
-+     a more robust implementation.

-+     [1] If the first response is a success we return success.
-+        This ignores the state of the second answer and in fact
-+        incorrectly sets errno and h_errno to that of the second
-+        answer.  However because the response is a success we ignore
-+        *errnop and *h_errnop (though that means you touched errno on
-+        success).  We are being conservative here and returning the
-+        likely IPv4 response in the first answer as a success.
-+
-+     [2] If the first response is a recoverable TRYAGAIN we return
-+        that instead of looking at the second response.  The
-+        expectation here is that we have failed to get an IPv4 response
-+        and should retry both queries.
-+
-+     [3] If the first response was not a SUCCESS and the second
-+        response is not NOTFOUND (had a SUCCESS, need to TRYAGAIN,
-+        or failed entirely e.g. TRYAGAIN' and UNAVAIL) then use the
-+        result from the second response, otherwise the first responses
-+        status is used.  Again we have some odd side-effects when the
-+        second response is NOTFOUND because we overwrite *errnop and
-+        *h_errnop that means that a first answer of NOTFOUND might see
-+        its *errnop and *h_errnop values altered.  Whether it matters
-+        in practice that a first response NOTFOUND has the wrong
-+        *errnop and *h_errnop is undecided.
-+
-+     [4] If the first response is UNAVAIL we return that instead of
-+        looking at the second response.  The expectation here is that
-+        it will have failed similarly e.g. configuration failure.
-+
-+     [5] Testing this code is complicated by the fact that truncated
-+        second response buffers might be returned as SUCCESS if the
-+        first answer is a SUCCESS.  To fix this we add symmetry to
-+        TRYAGAIN with the second response.  If the second response
-+        is a recoverable error we now return TRYAGIN even if the first
-+        response was SUCCESS.  */

-+/* The send_vc function is responsible for sending a DNS query over TCP
-+   to the nameserver numbered NS from the res_state STATP i.e.
-+   EXT(statp).nssocks[ns].  The function supports sending both IPv4 and
-+   IPv6 queries at the same serially on the same socket.
-+
-+   Please note that for TCP there is no way to disable sending both
-+   queries, unlike UDP, which honours RES_SNGLKUP and RES_SNGLKUPREOP
-+   and sends the queries serially and waits for the result after each
-+   sent query.  This implemetnation should be corrected to honour these
-+   options.
-+
-+   Please also note that for TCP we send both queries over the same
-+   socket one after another.  This technically violates best practice
-+   since the server is allowed to read the first query, respond, and
-+   then close the socket (to service another client).  If the server
-+   does this, then the remaining second query in the socket data buffer
-+   will cause the server to send the client an RST which will arrive
-+   asynchronously and the client's OS will likely tear down the socket
-+   receive buffer resulting in a potentially short read and lost
-+   response data.  This will force the client to retry the query again,
-+   and this process may repeat until all servers and connection resets
-+   are exhausted and then the query will fail.  It's not known if this
-+   happens with any frequency in real DNS server implementations.  This
-+   implementation should be corrected to use two sockets by default for
-+   parallel queries.
-+
-+   The query stored in BUF of BUFLEN length is sent first followed by
-+   the query stored in BUF2 of BUFLEN2 length.  Queries are sent
-+   serially on the same socket.
-+
-+   Answers to the query are stored firstly in *ANSP up to a max of
-+   *ANSSIZP bytes.  If more than *ANSSIZP bytes are needed and ANSCP
-+   is non-NULL (to indicate that modifying the answer buffer is allowed)
-+   then malloc is used to allocate a new response buffer and ANSCP and
-+   ANSP will both point to the new buffer.  If more than *ANSSIZP bytes
-+   are needed but ANSCP is NULL, then as much of the response as
-+   possible is read into the buffer, but the results will be truncated.
-+   When truncation happens because of a small answer buffer the DNS
-+   packets header field TC will bet set to 1, indicating a truncated
-+   message and the rest of the socket data will be read and discarded.
-+
-+   Answers to the query are stored secondly in *ANSP2 up to a max of
-+   *ANSSIZP2 bytes, with the actual response length stored in
-+   *RESPLEN2.  If more than *ANSSIZP bytes are needed and ANSP2
-+   is non-NULL (required for a second query) then malloc is used to
-+   allocate a new response buffer, *ANSSIZP2 is set to the new buffer
-+   size and *ANSP2_MALLOCED is set to 1.
-+
-+   The ANSP2_MALLOCED argument will eventually be removed as the
-+   change in buffer pointer can be used to detect the buffer has
-+   changed and that the caller should use free on the new buffer.
-+
-+   Note that the answers may arrive in any order from the server and
-+   therefore the first and second answer buffers may not correspond to
-+   the first and second queries.
-+
-+   It is not supported to call this function with a non-NULL ANSP2
-+   but a NULL ANSCP.  Put another way, you can call send_vc with a
-+   single unmodifiable buffer or two modifiable buffers, but no other
-+   combination is supported.
-+
-+   It is the caller's responsibility to free the malloc allocated
-+   buffers by detecting that the pointers have changed from their
-+   original values i.e. *ANSCP or *ANSP2 has changed.
-+
-+   If errors are encountered then *TERRNO is set to an appropriate
-+   errno value and a zero result is returned for a recoverable error,
-+   and a less-than zero result is returned for a non-recoverable error.
-+
-+   If no errors are encountered then *TERRNO is left unmodified and
-+   a the length of the first response in bytes is returned.  */

-+/* The send_dg function is responsible for sending a DNS query over UDP
-+   to the nameserver numbered NS from the res_state STATP i.e.
-+   EXT(statp).nssocks[ns].  The function supports IPv4 and IPv6 queries
-+   along with the ability to send the query in parallel for both stacks
-+   (default) or serially (RES_SINGLKUP).  It also supports serial lookup
-+   with a close and reopen of the socket used to talk to the server
-+   (RES_SNGLKUPREOP) to work around broken name servers.
-+
-+   The query stored in BUF of BUFLEN length is sent first followed by
-+   the query stored in BUF2 of BUFLEN2 length.  Queries are sent
-+   in parallel (default) or serially (RES_SINGLKUP or RES_SNGLKUPREOP).
-+
-+   Answers to the query are stored firstly in *ANSP up to a max of
-+   *ANSSIZP bytes.  If more than *ANSSIZP bytes are needed and ANSCP
-+   is non-NULL (to indicate that modifying the answer buffer is allowed)
-+   then malloc is used to allocate a new response buffer and ANSCP and
-+   ANSP will both point to the new buffer.  If more than *ANSSIZP bytes
-+   are needed but ANSCP is NULL, then as much of the response as
-+   possible is read into the buffer, but the results will be truncated.
-+   When truncation happens because of a small answer buffer the DNS
-+   packets header field TC will bet set to 1, indicating a truncated
-+   message, while the rest of the UDP packet is discarded.
-+
-+   Answers to the query are stored secondly in *ANSP2 up to a max of
-+   *ANSSIZP2 bytes, with the actual response length stored in
-+   *RESPLEN2.  If more than *ANSSIZP bytes are needed and ANSP2
-+   is non-NULL (required for a second query) then malloc is used to
-+   allocate a new response buffer, *ANSSIZP2 is set to the new buffer
-+   size and *ANSP2_MALLOCED is set to 1.
-+
-+   The ANSP2_MALLOCED argument will eventually be removed as the
-+   change in buffer pointer can be used to detect the buffer has
-+   changed and that the caller should use free on the new buffer.
-+
-+   Note that the answers may arrive in any order from the server and
-+   therefore the first and second answer buffers may not correspond to
-+   the first and second queries.
-+
-+   It is not supported to call this function with a non-NULL ANSP2
-+   but a NULL ANSCP.  Put another way, you can call send_vc with a
-+   single unmodifiable buffer or two modifiable buffers, but no other
-+   combination is supported.
-+
-+   It is the caller's responsibility to free the malloc allocated
-+   buffers by detecting that the pointers have changed from their
-+   original values i.e. *ANSCP or *ANSP2 has changed.
-+
-+   If an answer is truncated because of UDP datagram DNS limits then
-+   *V_CIRCUIT is set to 1 and the return value non-zero to indicate to
-+   the caller to retry with TCP.  The value *GOTSOMEWHERE is set to 1
-+   if any progress was made reading a response from the nameserver and
-+   is used by the caller to distinguish between ECONNREFUSED and
-+   ETIMEDOUT (the latter if *GOTSOMEWHERE is 1).
-+
-+   If errors are encountered then *TERRNO is set to an appropriate
-+   errno value and a zero result is returned for a recoverable error,
-+   and a less-than zero result is returned for a non-recoverable error.
-+
-+   If no errors are encountered then *TERRNO is left unmodified and
-+   a the length of the first response in bytes is returned.  */

-
-    strcoll: Remove incorrect STRDIFF-based optimization (Bug 18589).
-
-    The optimization introduced in commit
-    f13c2a8dff2329c6692a80176262ceaaf8a6f74e, causes regressions in
-    sorting for languages that have digraphs that change sort order, like
-    cs_CZ which sorts ch between h and i.
-
-    My analysis shows the fast-forwarding optimization in STRCOLL advances
-    through a digraph while possibly stopping in the middle which results
-    in a subsequent skipping of the digraph and incorrect sorting. The
-    optimization is incorrect as implemented and because of that I'm
-    removing it for 2.23, and I will also commit this fix for 2.22 where
-    it was originally introduced.
-
-    This patch reverts the optimization, introduces a new bug-strcoll2.c
-    regression test that tests both cs_CZ.UTF-8 and da_DK.ISO-8859-1 and
-    ensures they sort one digraph each correctly. The optimization can't be
-    applied without regressing this test.
-
-    Checked on x86_64, bug-strcoll2.c fails without this patch and passes
-    after. This will also get a fix on 2.22 which has the same bug.
-
-    (cherry picked from commit 87701a58e291bd7ac3b407d10a829dac52c9c16e)
