2008-06-06Remove superfluous attribute_hidden from functionDenis Vlasenko
definition. I seems to produce spurious warning: libc/inet/resolv.c:1549: warning: 'visibility' attribute ignored on non-class types (seems like gcc bug) and it is not really needed - attribute_hidden was already specified in function _declaration_ so it is not necessary here. No code changes (verified with objdump).

2008-06-04This fixes a problem with the move of libc_hidden_proto to string.h.Bernd Schmidt
The obsolete functions bcopy, index, etc. are not supposed to be used within uClibc itself. Hence, there is no libc_hidden_def for them, but the previous patch did not just move libc_hidden_protos, it also added new ones for the legacy functions. As a result, programs which use these functions can no longer link with uClibc. This fixes it by removing the unnecessary libc_hidden_protos. I've also removed all inclusions of <strings.h> from uClibc source files: since we define _GNU_SOURCE, it is sufficient to include <string.h>. We then do not need to duplicate the libc_hidden_proto block in <strings.h>.

2008-04-25reinstate external visibility of inet_ntoa_r,Denis Vlasenko
and add it to arpa/inet.h header.
2008-04-12Functions should be either exported in public .h filesDenis Vlasenko
and marked with libc_hidden_proto/def(), or not be exported in .h files and be hidden (or even static if possible). We have five functions which violate this. Fixing: netdb.h: export ruserpass() rpc/rpc.h: export xdr_accepted_reply() and xdr_rejected_reply() make inet_ntoa_r static function (it is not exported in any .h file) make _time_tzset hidden function (it is not exported in any .h file)

The following definitions in getaddrinfo.c seem redundant as they _are_ defined in the public netdb.h header, contrary to the comment. AI_DEFAULT is not, however it is not used in the file either so can be safely removed.

2008-01-09Daniel Jacobowitz writes:Mike Frysinger
MontaVista noticed that when their kernels were configured to trap on unaligned access gethostbyname_r could mysteriously crash. I tracked this down to an unaligned buffer being passed to gethostbyname_r from some other part of uClibc (afraid I don't remember where from any more). We have to pad the beginning of the buffer to a pointer alignment before we store pointers in it.
2007-09-28This patch will fix a problem when the same host is defined with both IPv4 andMike Frysinger
IPv6 entries in /etc/hosts. Previous only the first of these host would work, as uClibc would read the /etc/hosts file from top to bottom, failing if the first hit did not match the IP type. Now uClibc will continue reading, even if the first correct entry name, but wrong IP type fails. Thus, allowing a second correct entry name with correct IP type will result in a name resolve.

2007-02-02Ronald Maeder writes:Eric Andersen
Hi Erik, Thanks for all your great work. I found a set of bugs in resolv.c . Basically, there is code that looks like: BIGLOCK; __nameserversXX=__nameservers; __nameserverXX=__nameserver; BIGUNLOCK; i = __dns_lookup(dname, type, __nameserversXX, __nameserverXX, &packet, &a); which is a problem because the declarations are int __nameservers; char * __nameserver[MAX_SERVERS]; int __searchdomains; char * __searchdomain[MAX_SEARCH]; so you can see that __nameserver is a pointer. Copying the pointer to __nameserverXX doesn't protect the global variable space. I have attached a patch and the new file. I hope you will incorporate these bug fixes. I spent quite a bit of time tracking them down. Many thanks, Ron
2007-02-02fix obvious bug in ipv4/ipv6 resolving. When not using AF_INET,Eric Andersen
gethostbyname2_r tries to resolve an ipv6 address from /etc/hosts using get_hosts_byname_r, but with AF_INET instead of the supplied address family. This returns ipv4 addresses marked as ipv6 ones. Fix from nbd.
