2Quote from bug 1443 which explains what the patch does :
3
4 We build some random program and link it with -lust. When we run it,
5 it dies with a SIGSEGV before reaching main().
6
7 Libust.so depends on liburcu-bp.so from the usermode-rcu package.
8 Although libust.so is not prelinked, liburcu-bp.so IS prelinked; this
9 is critical.
10
11 Libust.so uses a TLS / __thread variable that is defined in liburcu-
12 bp.so. There are special ARM-specific relocation types that allow two
13 shared libraries to share thread-specific data. This is critical too.
14
15 One more critical issue: although liburcu-bp.so is prelinked, we can't
16 load it at its prelinked address, because we also link against
17 librt.so, and librt.so uses that address.
18
19 The dynamic linker is forced to relink liburcu-bp.so at a different
20 address. In the course of relinking, it processes the special ARM
21 relocation record mentioned above. The prelinker has already filled
22 in the information, which is a short offset into a table of thread-
23 specific data that is allocated per-thread for each library that uses
24 TLS. Because the normal behavior of a relocation is to add the symbol
25 value to an addend stored at the address being relocated, we end up
26 adding the short offset to itself, doubling it.
27
28 Now we have an awkward situation. The libust.so library doesn't know
29 about the addend, so its TLS data for this element is correct. The
30 liburcu-bp.so library has a different offset for the element. When we
31 go to initialize the element for the first time in liburcu-bp.so, we
32 write the address of the result at the doubled (broken) offset.
33 Later, when we refer to the address from libust.so, we check the value
34 at the correct offset, but it's NULL, so we eat hot SIGSEGV.

7Hi,
8
9This patch adds 'make menuconfig' support to EGLIBC.
10
11
12EGLIBC can re-use the Linux kernel kconfig host tools ('conf' and 'mconf') unmodified, by passing appropriate environment variables and with some pre- and post-processing on the input/output config files.
13
14There are three new make targets supported, which all are defined in the new libc/options-config/Makefile, which is included by the top-level libc/Makefile:
15
16- 'make defconfig'. This passes 'libc/option-groups.defaults' to 'conf' as a default config, and outputs 'option-groups.config' to the top-level build directory, which will be the same as the default config.
17
18- 'make config'. This is the same line-oriented interface as in the Linux kernel. Input and output is 'option-groups.config' in the top-level build directory.
19
20- 'make menuconfig'. This is the same menu-based interface as in the Linux kernel. Input and output is 'option-groups.config' in the top-level build directory.
21
22
23Pre-Processing:
24
25
26The Linux kernel kconfig tools expect a prefix of "CONFIG_" on all config option names, but EGLIBC expects a prefix of "OPTION_". The pre-processing script, libc/options-config/config-preproc.pl, simply replaces "CONFIG_ with "OPTION_" in the given config file. The libc/options-config/Makefile passes the script output to a temporary config file, which is then passed to 'conf' or 'mconf'.
27
28Post-Processing (libc/options-config/config-postproc.pl):
29
30
31- Disabled options are output as a comment line of the form "# CONFIG_FOO is not set". This needs to be changed to an explicit "CONFIG_FOO=n" in order to be compatible with 'option-groups.awk' which generates the option-groups.h header.
32
33- "CONFIG_" prefix is changed back to "OPTION_".
34
35
36- The kconfig tools will not output anything for options that depend on a parent option, when the parent option is disabled. This implicit disable must be converted to an explicit "CONFIG_FOO=n" in order to be compatible with the way EGLIBC overrides the default option settings in 'libc/option-groups.defaults' with those in 'option-groups.config'.
37
38
39A new configure option, '--with-kconfig=<PATH>', tells EGLIBC where to find the pre-built 'conf' and 'mconf' host tools from Linux kernel builds.
40
41libc/EGLIBC.cross-building is updated to include instructions for using '--with-kconfig' for the final EGLIBC build, and shows how and when to run 'make *config'.
42
43libc/EGLIBC.option-groups is updated to include new information on the menuconfig support.
44
45Thanks,
46
47attached is the updated patch to address above issues.

71+Note the additional '--with-kconfig' option. This tells EGLIBC where to
72+find the host config tools used by the kernel 'make config' and 'make
73+menuconfig'. These tools can be re-used by EGLIBC for its own 'make
74+*config' support, which will create 'option-groups.config' for you.
75+But first make sure those tools have been built by running some
76+dummy 'make *config' calls in the kernel directory:

4Subject: [PATCH] eglibc: run libm-err-tab.pl with specific dirs in ${S}
5
6libm-err-tab.pl will parse all the files named "libm-test-ulps"
7in the given dir recursively. To avoid parsing the one in
8${S}/.pc/ (it does exist after eglibc adds aarch64 support,
9${S}/.pc/aarch64-0001-glibc-fsf-v1-eaf6f205.patch/ports/sysdeps/
10aarch64/libm-test-ulps), run libm-err-tab.pl with specific dirs
11in ${S}.

10This patch builds on the menuconfig patch for EGLIBC.
11
12
13There are a few options that have non-boolean types, that would benefit from the new 'make *config' support:
14
15EGLIBC_MEMUSAGE_DEFAULT_BUFFER_SIZE (int)
16EGLIBC_NSSWITCH_FIXED_CONFIG (string)
17EGLIBC_NSSWITCH_FIXED_FUNCTIONS (string)
18
19
20The patch converts these to real options in libc/option-groups.def. Also, libc/scripts/option-groups.awk is modified to output a '#define' line for int, hex, or string options encountered in the config file.
21
22In the post-processing script config-postproc.pl, a small change is needed: for any boolean option FOO that is implicitly disabled in the kconfig output, make sure that option is indeed a boolean before printing the explicit OPTION_FOO=n.
23
24Finally, libc/malloc/Makefile passes __OPTION_EGLIBC_MEMUSAGE_DEFAULT_BUFFER_SIZE as a CPPFLAGS, which is not necessary anymore because this macro will now be present in the generated header.
25
26attached is the updated patch to address above issues.

8As part of the menuconfig development, I encountered some outdated information in the cross-build instructions, libc/EGLIBC.cross-building. This patch updates the file with new (and tested) instructions. It is unrelated to the menuconfig support, but applies after.
9
10My testing was done with an ARM target, and an x86_64 Linux host, so I converted the instructions to use those host/target types from the original i686/powerpc. Hope that's ok.

3The default lib search path order is:
4
5 1) LD_LIBRARY_PATH
6 2) RPATH from the binary
7 3) ld.so.cache
8 4) default search paths embedded in the linker
9
10For nativesdk binaries which are being used alongside binaries on a host system, we
11need the search paths to firstly search the shipped nativesdk libs but then also
12cover the host system. For example we want the host system's libGL and this may be
13in a non-standard location like /usr/lib/mesa. The only place the location is know
14about is in the ld.so.cache of the host system.
15
16Since nativesdk has a simple structure and doesn't need to use a cache itself, we
17repurpose the cache for use as a last resort in finding host system binaries. This
18means we need to switch the order of 3 and 4 above to make this work effectively.

3This patch puts the dynamic loader path in the binaries, SYSTEM_DIRS strings
4and lengths as well as ld.so.cache path in the dynamic loader to specific
5sections in memory. The sections that contain paths have been allocated a 4096
6byte section, which is the maximum path length in linux. This will allow the
7relocating script to parse the ELF binary, detect the section and easily replace
8the strings in a certain path.

3eglibc-nativesdk: Fix buffer overrun with a relocated SDK
4
5When ld-linux-*.so.2 is relocated to a path that is longer than the
6original fixed location, the dynamic loader will crash in open_path
7because it implicitly assumes that max_dirnamelen is a fixed size that
8never changes.
9
10The allocated buffer will not be large enough to contain the directory
11path string which is larger than the fixed location provided at build
12time.
