-+
-+ 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

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

-+/* 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.
-+
-+ (The non-reentrant 'getXbyKEY' functions are implemented in terms
-+ of the reentrant 'getXbyKEY_r' functions, so there is no need to
-+ refer to them explicitly here.)
-+
-+ Use the special key 'name3' for the service library function that
-+ implements the 'getaddrinfo' function.
-+
-+ - DEFINE_GET (DATABASE, SERVICE, QUERY)
-+
-+ Declare the 'getQUERY_r' functions that query DATABASE using
-+ SERVICE. This is used for functions like 'getpwnam'.
-+
-+ (The non-reentrant 'getQUERY' functions are implemented in terms
-+ of the reentrant 'getQUERY_r' functions, so there is no need to
-+ refer to them explicitly here.)
-+
-+ This sample file only includes functions that consult the files in
-+ '/etc', and the Domain Name System (DNS). */

-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.

-Subject: [PATCH] CVE-2015-7547: getaddrinfo() stack-based buffer overflow (Bug
- 18665).
-
-* A stack-based buffer overflow was found in libresolv when invoked from
- libnss_dns, allowing specially crafted DNS responses to seize control
- of execution flow in the DNS client. The buffer overflow occurs in
- the functions send_dg (send datagram) and send_vc (send TCP) for the
- NSS module libnss_dns.so.2 when calling getaddrinfo with AF_UNSPEC
- family. The use of AF_UNSPEC triggers the low-level resolver code to
- send out two parallel queries for A and AAAA. A mismanagement of the
- buffers used for those queries could result in the response of a query
- writing beyond the alloca allocated buffer created by
- _nss_dns_gethostbyname4_r. Buffer management is simplified to remove
- the overflow. Thanks to the Google Security Team and Red Hat for
- reporting the security impact of this issue, and Robert Holiday of
- Ciena for reporting the related bug 18665. (CVE-2015-7547)

-+ ----------------------------------------------
-+
-+ [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

-+ buffers by detecting that the pointers have changed from their

-+ errno value and a zero result is returned for a recoverable error,

- 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)

+Subject: [pseudo][PATCH] configure: Prune PIE flags
+
+LDFLAGS are not taken from environment and CFLAGS is used for LDFLAGS
+however when using security options -fpie and -pie options are coming
+as part of ARCH_FLAGS and they get into LDFLAGS of shared objects as
+well so we end up with conflicting options -shared -pie, which gold
+rejects outright and bfd linker lets the one appearning last in cmdline
+take effect. This create quite a unpleasant situation in OE when
+security flags are enabled and gold or not-gold options are used
+it errors out but errors are not same.
+
+Anyway, with this patch we filter pie options from ARCH_FLAGS
+ouright and take control of generating PIC objects
+
+Helps with errors like
+
+| /mnt/oe/build/tmp-glibc/sysroots/x86_64-linux/usr/libexec/x86_64-oe-linux/gcc/x86_64-oe-linux/5.3.0/ld: pseudo_client.o: relocation R_X86_64_PC32 against symbol `pseudo_util_debug_flags' can not be used when making a shared object; recompile with -fPIC

Hi All,
For the latest master, if 'DEBUG_BUILD' is enabled, the above error appers.
| ../sysdeps/unix/sysv/linux/posix_fallocate.c: In function
'posix_fallocate':
| ../sysdeps/unix/sysv/linux/posix_fallocate.c:39:1: error: bp cannot be
used in asm here
| }
| ^
The problem could be reproduced if we add in local.conf the following line.
DEBUG_BUILD = "1"
Do you have any idea what's going on there?
Regards,
Chen Qi

posix_fallocate is calling a syscall helper with 6 argument, and there has been i386 specific optimization added to glibc
which checks for gcc version and if its >= 5.0 then relies upon gcc to do right thing when spilling ebp, and switched to using
inline syscall handler. But this spill is working/tested with -O2 and everything else is just a bonus if it works. Can you try this
patch to glibc ?

Hi Khem,
Thanks for your reply.
I've tried the above patch, but the problem is still there :(

And if we remove " -fno-omit-frame-pointer" from CFLAGS, things work.
CFLAGS_remove_pn-glibc_x86 = " -fno-omit-frame-pointer"
