| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* fix obvious bug in ipv4/ipv6 resolving. When not using AF_INET,Eric Andersen2007-02-021-1/+1
| | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
