2008-01-11Use poll() rather than select() if the former is available to wait inPeter Kjellerstedt
__dns_lookup(). This avoids segmentation faults when more than 1024 file descriptors are used by an application.

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.

I have successfully made gethostbyname_r(), res_init(), and gethostid() fully reentrant. In addition, I have added a NULL check to inet_aton(). This is where SEG FAULTs were coming from when gethostbyname_r() was called.

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.

things, and avoid potential deadlocks caused when a thread holding a uClibc internal lock get canceled and terminates without releasing the lock. This change also provides a single place, bits/uClibc_mutex.h, for thread libraries to modify to change all instances of internal locking.
