2005-09-08[PATCH] Fix 32bit sendmsg() flawAl Viro-19/+28
When we copy 32bit ->msg_control contents to kernel, we walk the same userland data twice without sanity checks on the second pass. Second version of this patch: the original broke with 64-bit arches running 32-bit-compat-mode executables doing sendmsg() syscalls with unaligned CMSG data areas Another thing is that we use kmalloc() to allocate and sock_kfree_s() to free afterwards; less serious, but also needs fixing.

2005-09-07[PATCH] sunrpc: print unsigned integers in statsMax Kellermann-8/+8
The sunrpc stats are collected in unsigned integers, but they are printed with '%d'. That can result in negative numbers in /proc/net/rpc when the highest bit of a counter is set. The following patch changes '%d' to '%u' where appropriate. Cc: "David S.

2005-09-07[PATCH] sunrpc: cache_register can use wrong module referenceBruce Allan-8/+16
When registering an RPC cache, cache_register() always sets the owner as the sunrpc module. However, there are RPC caches owned by other modules. With the incorrect owner setting, the real owning module can be removed potentially with an open reference to the cache from userspace. For example, if one were to stop the nfs server and unmount the nfsd filesystem, the nfsd module could be removed eventhough rpc.idmapd had references to the idtoname and nametoid caches (i.e. /proc/net/rpc/nfs4.<cachename>/channel is still open). This resulted in a system panic on one of our machines when attempting to restart the nfs services after reloading the nfsd module. The following patch adds a 'struct module *owner' field in struct cache_detail. The owner is further assigned to the struct proc_dir_entry in cache_register() so that the module cannot be unloaded while user-space daemons have an open reference on the associated file under /proc.

2005-09-06[PATCH] WE-19 for kernel 2.6.13Jean Tourrilhes-24/+34
Hi Jeff, This is version 19 of the Wireless Extensions. It was supposed to be the fallback of the WPA API changes, but people seem quite happy about it (especially Jouni), so the patch is rather small. The patch has been fully tested with 2.6.13 and various wireless drivers, and is in its final version. Would you mind pushing that into Linus's kernel so that the driver and the apps can take advantage ot it ? It includes : o iwstat improvement (explicit dBm). This is the result of long discussions with Dan Williams, the authors of NetworkManager. Thanks to him for all the fruitful feedback. o remove pointer from event stream. I was not totally sure if this pointer was 32-64 bits clean, so I'd rather remove it and be at peace with it. o remove linux header from wireless.h. This has long been requested by people writting user space apps, now it's done, and it was not even painful. o final deprecation of spy_offset. You did not like it, it's now gone for good. o Start deprecating dev->get_wireless_stats -> debloat netdev o Add "check" version of event macros for ieee802.11 stack. Jiri Benc doesn't like the current macros, we aim to please ;-) All those changes, except the last one, have been bit-roting on my web pages for a while... Patches for most kernel drivers will follow. Patches for the Orinoco and the HostAP drivers have been sent to their respective maintainers. Have fun...

This is especially important with CONFIG_NETFILTER_DEBUG, the netfilter listhelp functions will refuse to remove an entry from a list when it can not be found on the list, so when a changed tuple hashes to a new bucket the entry is kept in the list until and after the conntrack is freed.

The switch statement will fall through to the default case and return 0 for all cases but 0 > k >= SKF_AD_OFF. Here's a patch to do just that.

2005-09-01[TCP]: Fix sk_forward_alloc underflow in tcp_sendmsgHerbert Xu-5/+9
I've finally found a potential cause of the sk_forward_alloc underflows that people have been reporting sporadically. When tcp_sendmsg tacks on extra bits to an existing TCP_PAGE we don't check sk_forward_alloc even though a large amount of time may have elapsed since we allocated the page. In the mean time someone could've come along and liberated packets and reclaimed sk_forward_alloc memory. This patch makes tcp_sendmsg check sk_forward_alloc every time as we do in do_tcp_sendpages.

2005-09-01[CRYPTO]: crypto_free_tfm() callers no longer need to check for NULLJesper Juhl-84/+42
Since the patch to add a NULL short-circuit to crypto_free_tfm() went in, there's no longer any need for callers of that function to check for NULL. This patch removes the redundant NULL checks and also a few similar checks for NULL before calls to kfree() that I ran into while doing the crypto_free_tfm bits. I've succesfuly compile tested this patch, and a kernel with the patch applied boots and runs just fine. When I posted the patch to LKML (and other lists/people on Cc) it drew the following comments : J. Bruce Fields commented "I've no problem with the auth_gss or nfsv4 bits.--b." Sridhar Samudrala said "sctp change looks fine." Herbert Xu signed off on the patch. So, I guess this is ready to be dropped into -mm and eventually mainline.
