2016-03-10getaddrinfo: correct AI_V4MAPPED handlingPeter Korsgaard
As recently reported on the Buildroot list: http://lists.busybox.net/pipermail/buildroot/2016-March/155325.html DNS lookups with Node.js currently fails on uClibc-ng. The reason for this is the way AI_V4MAPPED is handled. According to POSIX, AI_V4MAPPED should be ignored unless ai_family is AF_INET6: http://pubs.opengroup.org/onlinepubs/9699919799/functions/freeaddrinfo.html If the AI_V4MAPPED flag is specified along with an ai_family of AF_INET6, then getaddrinfo() shall return IPv4-mapped IPv6 addresses on finding no matching IPv6 addresses (ai_addrlen shall be 16). The AI_V4MAPPED flag shall be ignored unless ai_family equals AF_INET6. uClibc-ng was also handling AI_V4MAPPED for AF_UNSPEC, fix that. Signed-off-by: Peter Korsgaard <peter@korsgaard.com>
2016-03-10DNS: Don't apply search domains to PTR lookupsTim Hockin
This lessens the load on upstream DNS servers (and it was just nonsensical). Signed-off-by: Tim Hockin <thockin@google.com>
2016-03-10DNS: don't count search-path miss as a retryTim Hockin
Currently a miss on a search-path entry is counted as a retry. This means that users with more than (num_nameservers * retries) entries in their search path list fail before trying all search paths. Concretely, a single nameserver with 4 search paths will never try the 4th search because the default retry is 3. The code doesn't currently retry a given nameserver in case of an error, so retries is sort of meaningless (though there are some comments indicating it might come). This change only treats total failure of a nameserver (try next server) as a retry. Signed-off-by: Tim Hockin <thockin@google.com>

2016-02-29arm: fix __JMP_BUF_SP definitionMax Filippov
__JMP_BUF_SP is the index of a stack pointer slot in the __jmp_buf. According to ARM __sigsetjmp code it does not depend on configuration parameter __UCLIBC_HAS_FPU__. Make its definition unconditional. __JMP_BUF_SP is used in the unwind_stop through the _JMPBUF_CFA_UNWINDS_ADJ macro, this change fixes cleanup routines call on thread cancellation in configurations with hard FP.

2016-02-24xtensa: fix stack unwinding over __default_sa_restorerMax Filippov
For some xtensa cores generated code gets arranged so that __default_sa_restorer immediately follows preceding function. E.g.: 40a1b: c03340 sub a3, a3, a4 40a1e: f01d retw.n 00040a20 <__default_sa_restorer>: 40a20: e1a022 movi a2, 225 40a23: 005000 syscall ... Contents of the .eh_frame section: ... 000007f4 00000014 000007f8 FDE cie=00000000 pc=0004076c..00040a20 DW_CFA_advance_loc4: 3 to 0004076f DW_CFA_def_cfa_offset: 48 Due to the way xtensa libgcc uw_frame_state_for calls _Unwind_Find_FDE for non-signal frames, FDE for the previous function is found during thread cancellation signal stack unwinding in that case. Signal stack frame is not recognized and is not unwound properly, breaking cleanup routines calling for cancelled thread. Insert padding before the __default_sa_restorer so that no FDE is found for it, MD_FALLBACK_FRAME_STATE_FOR is called by uw_frame_state_for and the frame is correctly recognized as signal frame.

2016-02-24ARC: Disable obstackAnton Kolesov
Obstack was enabled in ARC defconfig to enable builds of native binutils and GDB. This is not needed after earlier patch which removes invalid _GNU_OBSTACK_INTERFACE_VERSION definition in cases when obstack is not selected in uClibc configuration. With this change binutils and GDB would use obstack implementation from their own source trees. In fact with recent binutils it is not possible to build it using obstack implementation in uClibc, because binutils/include/obstack.h started to use _obstack_free function instead of obstack_free, but _obstack_free is not defined in uClibc.

2016-02-24Advertise obstack only when chosenAnton Kolesov
This is similar to this patch for GNU glob: ff6ce3999db93a52d1cd22510f8508b660ddf54e. The problem is that libiberty/obstack.c file checks for _GNU_OBSTACK_INTERFACE_VERSION == _OBSTACK_INTERFACE_VERSION and elides libiberty obstack implementation if there is already a compatible implementation in libc. Therefore define should be set only when obstack is actually selected, otherwise it is not possible to build binutils and gdb with uClibc.

2016-02-07frv: resurrect port somehow, totally untestedWaldemar Brodkorb
The FR-V port is really broken, and I have no emulator or hardware for this platform. I tried to get some hardware from RedHat, who made the FR-V port initially. Unfortunately Fujitsi didn't agreed to sent me some of their unused spare hardware lying @RedHat. As I invested some time to get stuff compiled, I decided to add the code and may be anytime later I can gain access to some emulator or hardware. GDB simulator for FR-V doesn't support booting Linux AFAIK.

2016-02-02include/netdb.h: Do not define IDN-related flags.Thomas Claveirole
getaddrinfo() does not implement IDN encoding, and always fail when provided an IDN flag (e.g., AI_IDN) with EAI_BADFLAGS. Some packages (such as the VLC media player) check for AI_IDN before they use it; providing an unimplemented AI_IDN in the libc makes these package fail. As a result they make calls to getaddrinfo() with AI_IDN that always fail while they could have made successful calls without AI_IDN instead. Thus, do not define IDN flags: it is better not to compile rather than to compile a code that always fail. Signed-off-by: Thomas Claveirole <thomas.claveirole@green-communications.fr>

ARCH_NATIVE_BIT should in the first place be passed when building utils for host (BUILD_CFLAGS-utils). It could also be passed when building utils for target (CFLAGS-utils), but this is actually not necessary as ARCH_NATIVE_BIT and __WORDSIZE are identical in this case.
