2015-03-31Replace __attribute__((visibility("protected")))hjl/pr17711/2.19H.J. Lu
With copy relocation, address of protected data defined in the shared library may be external. Compiler shouldn't asssume protected data will be local. But due to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65248 __attribute__((visibility("protected"))) doesn't work correctly, we need to use asm (".protected xxx") instead. Cherry-pick from master: e0ed2fb40a0e29c43cf60addc74741dab15f2e05 * elf/ifuncdep2.c (global): Replace __attribute__((visibility("protected"))) with asm (".protected global"). * elf/ifuncmod1.c (global): Likewise. * elf/ifuncmod5.c (global): Likewise.
2015-03-31Add a testcase for copy reloc against protected dataH.J. Lu
Linkers in some versions of binutils 2.25 and 2.26 don't support protected data symbol with error messsage like: /usr/bin/ld: copy reloc against protected `bar' is invalid /usr/bin/ld: failed to set dynamic section sizes: Bad value We check if linker supports copy reloc against protected data symbol to avoid running the test if linker is broken. Cherry-pick from master: 83569fb894050db7430047da2219ca50c68f882a [BZ #17711] * config.make.in (have-protected-data): New. * configure.ac: Check linker support for protected data symbol. * configure: Regenerated. * elf/Makefile (modules-names): Add tst-protected1moda and tst-protected1modb if $(have-protected-data) is yes. (tests): Add tst-protected1a and tst-protected1b if $(have-protected-data) is yes. ($(objpfx)tst-protected1a): New. ($(objpfx)tst-protected1b): Likewise. (tst-protected1modb.so-no-z-defs): Likewise. * elf/tst-protected1a.c: New file. * elf/tst-protected1b.c: Likewise. * elf/tst-protected1mod.h: Likewise. * elf/tst-protected1moda.c: Likewise. * elf/tst-protected1modb.c: Likewise.
2015-03-31Add ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA to x86H.J. Lu
With copy relocation, address of protected data defined in the shared library may be external. When there is a relocation against the protected data symbol within the shared library, we need to check if we should skip the definition in the executable copied from the protected data. This patch adds ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA and defines it for x86. If ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA isn't 0, do_lookup_x will skip the data definition in the executable from copy reloc. Cherry-pick from master: 62da1e3b00b51383ffa7efc89d8addda0502e107 [BZ #17711] * elf/dl-lookup.c (do_lookup_x): When UNDEF_MAP is NULL, which indicates it is called from do_lookup_x on relocation against protected data, skip the data definion in the executable from copy reloc. (_dl_lookup_symbol_x): Pass ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA, instead of ELF_RTYPE_CLASS_PLT, to do_lookup_x for EXTERN_PROTECTED_DATA relocation against STT_OBJECT symbol. * sysdeps/generic/ldsodefs.h * (ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA): New. Defined to 4 if DL_EXTERN_PROTECTED_DATA is defined, otherwise to 0. * sysdeps/i386/dl-lookupcfg.h (DL_EXTERN_PROTECTED_DATA): New. * sysdeps/i386/dl-machine.h (elf_machine_type_class): Set class to ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA for R_386_GLOB_DAT. * sysdeps/x86_64/dl-lookupcfg.h (DL_EXTERN_PROTECTED_DATA): New. * sysdeps/x86_64/dl-machine.h (elf_machine_type_class): Set class to ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA for R_X86_64_GLOB_DAT.

2014-09-05Use NSS_STATUS_TRYAGAIN to indicate insufficient buffer (BZ #16878)Siddhesh Poyarekar
The netgroups nss modules in the glibc tree use NSS_STATUS_UNAVAIL (with errno as ERANGE) when the supplied buffer does not have sufficient space for the result. This is wrong, because the canonical way to indicate insufficient buffer is to set the errno to ERANGE and the status to NSS_STATUS_TRYAGAIN, as is used by all other modules. This fixes nscd behaviour when the nss_ldap module returns NSS_STATUS_TRYAGAIN to indicate that a netgroup entry is too long to fit into the supplied buffer.

2014-09-05Provide correct buffer length to netgroup queries in nscd (BZ #16695)Siddhesh Poyarekar
The buffer to query netgroup entries is allocated sufficient space for the netgroup entries and the key to be appended at the end, but it sends in an incorrect available length to the NSS netgroup query functions, resulting in overflow of the buffer in some special cases. The fix here is to factor in the key length when sending the available buffer and buffer length to the query functions.

If the glibc xattr.h header is included after the uapi header, compilation fails due to an enum re-using a #define from the uapi header. Protect against this by guarding the define and enum inclusions against each other. (A corresponding kernel patch has been sent here: http://lkml.org/lkml/2014/3/7/331 ) (See https://lists.debian.org/debian-glibc/2014/03/msg00029.html and https://sourceware.org/glibc/wiki/Synchronizing_Headers for more information.)

When compiling with pedantic the following warning is seen: gcc -Wall -pedantic -O0 -o test test.c In file included from test.c:3:0: /path/inet/netinet/in.h:111:21: warning: comma at end of \ enumerator list [-Wpedantic] IPPROTO_MH = 135, /* IPv6 mobility header. */ ^ It is valid C99 to have a trailing comma after the last item in an enumeration. However it is not valid C90. If possible glibc attempts to keep all headers C90 + long long without requiring C99 features. In this case it's easy to fix the headers and it removes the warning seem with -pedantic.
