2005-09-07[PATCH] sunrpc: print unsigned integers in statsGravatar Max Kellermann 1-8/+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. Miller" <davem@davemloft.net> Cc: Trond Myklebust <trond.myklebust@fys.uio.no> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-09-07[PATCH] sunrpc: cache_register can use wrong module referenceGravatar Bruce Allan 5-8/+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.

2005-09-05[NET]: 2.6.13 breaks libpcap (and tcpdump)Gravatar Herbert Xu 1-3/+3
Patrick McHardy says: Never mind, I got it, we never fall through to the second switch statement anymore. I think we could simply break when load_pointer returns NULL. 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. I left BPF_MSH alone because it's really a hack to calculate the IP header length, which makes no sense when applied to the special data.

2005-09-01[TCP]: Fix sk_forward_alloc underflow in tcp_sendmsgGravatar Herbert Xu 1-5/+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[IPV6]: Repair Incoming Interface Handling for Raw Socket.Gravatar YOSHIFUJI Hideaki 2-3/+3
Due to changes to enforce checking interface bindings, sockets did not see loopback packets bound for our local address on our interface. e.g.) When we ping6 fe80::1%eth0, skb->dev points loopback_dev while IP6CB(skb)->iif indicates eth0.

2005-09-01[CRYPTO]: crypto_free_tfm() callers no longer need to check for NULLGravatar Jesper Juhl 12-84/+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.

2005-08-29[CCID3]: Call sk->sk_write_space(sk) when receiving a feedback packetGravatar Arnaldo Carvalho de Melo 4-0/+20
This makes the send rate calculations behave way more closely to what is specified, with the jitter previously seen on x and x_recv disappearing completely on non lossy setups. This resembles the tcp_data_snd_check code, that possibly we'll end up using in DCCP as well, perhaps moving this code to inet_connection_sock. For now I'm doing the simplest implementation tho.

I'll now take a look at the other proposed TFRC DCCP CCIDs to find more code that is now in ccid3.c and move to this module, the loss event rate, calc_X, etc most probably will be moved there.

2005-08-29[CCID3]: Reorganise timeval handlingGravatar Arnaldo Carvalho de Melo 3-78/+98
Introducing functions to add to or subtract from a timeval variable and renaming now_delta to timeval_new_delta that calls do_gettimeofday and then timeval_delta, that should be used when there are several deltas made relative to the current time or setting variables to it, so as to avoid calling do_gettimeofday excessively. I'm leaving these "timeval_" prefixed funcions internal to DCCP for a while till we're sure there are no subtle bugs in it. It also is more correct as it checks if the number of usecs added to or subtracted from a tv_usec field is more than 2 seconds.
