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.

identical cc1 input for LFS enabled (compared to before r17652) but makes sure that we pickup the non-LFS if LFS is turned off (like r17652 did in this case).

Sounds like a typo, really

However, retesting on m68k showed up a problem that had appeared in uClibc since the last time I tried. Specifically, revision 15785 did: -#define HEAP_GRANULARITY (sizeof (HEAP_GRANULARITY_TYPE)) +#define HEAP_GRANULARITY (__alignof__ (HEAP_GRANULARITY_TYPE)) -#define MALLOC_ALIGNMENT (sizeof (double)) +#define MALLOC_ALIGNMENT (__alignof__ (double)) The problem is that (a) MALLOC_HEADER_SIZE == MALLOC_ALIGNMENT (b) the header contains a size value of type size_t (c) sizeof (size_t) is 4 on m68k, but... (d) __alignof__ (double) is only 2 (the largest alignment used on m68k) So we only allocate 2 bytes for the 4-byte header, and the least significant 2 bytes of the size are in the user's area rather than the header. The patch below fixes that problem by redefining MALLOC_HEADER_SIZE to: MAX (MALLOC_ALIGNMENT, sizeof (size_t)) (but without the help of the MAX macro ;)). However, we really would like to have word alignment on Coldfire. It makes a big performance difference, and because we have to allocate a 4-byte header anyway, what wastage there is will be confined to the end of the allocated block. Any wastage will also be limited to 2 bytes per allocation compared to the current alignment. I've therefore used the __aligned__ type attribute to create a double type that has at least sizeof (size_t) bytes of alignment. I've introduced a new __attribute_aligned__ macro for this. It might seem silly protecting against old or non-GNU compilers here, but the extra alignment is only an optimisation, and having the macro is more in the spirit of the other attribute code.
