2010-09-24net: fix a lockdep splatEric Dumazet1-14/+14
We have for each socket : One spinlock (sk_slock.slock) One rwlock (sk_callback_lock) Possible scenarios are : (A) (this is used in net/sunrpc/xprtsock.c) read_lock(&sk->sk_callback_lock) (without blocking BH) <BH> spin_lock(&sk->sk_slock.slock); ... read_lock(&sk->sk_callback_lock); ... (B) write_lock_bh(&sk->sk_callback_lock) stuff write_unlock_bh(&sk->sk_callback_lock) (C) spin_lock_bh(&sk->sk_slock) ... write_lock_bh(&sk->sk_callback_lock) stuff write_unlock_bh(&sk->sk_callback_lock) spin_unlock_bh(&sk->sk_slock) This (C) case conflicts with (A) : CPU1 [A] CPU2 [C] read_lock(callback_lock) <BH> spin_lock_bh(slock) <wait to spin_lock(slock)> <wait to write_lock_bh(callback_lock)> We have one problematic (C) use case in inet_csk_listen_stop() : local_bh_disable(); bh_lock_sock(child); // spin_lock_bh(&sk->sk_slock) WARN_ON(sock_owned_by_user(child)); ... sock_orphan(child); // write_lock_bh(&sk->sk_callback_lock) lockdep is not happy with this, as reported by Tetsuo Handa It seems only way to deal with this is to use read_lock_bh(callbacklock) everywhere. Thanks to Jarek for pointing a bug in my first attempt and suggesting this solution.

2010-09-12sunrpc: increase MAX_HASHTABLE_BITS to 14Miquel van Smoorenburg1-1/+1
The maximum size of the authcache is now set to 1024 (10 bits), but on our server we need at least 4096 (12 bits). Increase MAX_HASHTABLE_BITS to 14. This is a maximum of 16384 entries, each containing a pointer (8 bytes on x86_64). This is exactly the limit of kmalloc() (128K).

2010-09-12SUNRPC: cleanup state-machine orderingJ. Bruce Fields1-42/+42
This is just a minor cleanup: net/sunrpc/clnt.c clarifies the rpc client state machine by commenting each state and by laying out the functions implementing each state in the order that each state is normally executed (in the absence of errors). The previous patch "Fix null dereference in call_allocate" changed the order of the states. Move the functions and update the comments to reflect the change. Signed-off-by: J.

2010-09-12SUNRPC: Fix race corrupting rpc upcallTrond Myklebust2-7/+8
If rpc_queue_upcall() adds a new upcall to the rpci->pipe list just after rpc_pipe_release calls rpc_purge_list(), but before it calls gss_pipe_release (as rpci->ops->release_pipe(inode)), then the latter will free a message without deleting it from the rpci->pipe list. We will be left with a freed object on the rpc->pipe list. Most frequent symptoms are kernel crashes in rpc.gssd system calls on the pipe in question. Reported-by: J.

2010-09-12Fix null dereference in call_allocateJ. Bruce Fields1-4/+4
In call_allocate we need to reach the auth in order to factor au_cslack into the allocation. As of a17c2153d2e271b0cbacae9bed83b0eaa41db7e1 "SUNRPC: Move the bound cred to struct rpc_rqst", call_allocate attempts to do this by dereferencing tk_client->cl_auth, however this is not guaranteed to be defined--cl_auth can be zero in the case of gss context destruction (see rpc_free_auth). Reorder the client state machine to bind credentials before allocating, so that we can instead reach the auth through the cred. Signed-off-by: J.

2010-08-11param: use ops in struct kernel_param, rather than get and set fns directlyRusty Russell1-11/+15
This is more kernel-ish, saves some space, and also allows us to expand the ops without breaking all the callers who are happy for the new members to be NULL. The few places which defined their own param types are changed to the new scheme (more which crept in recently fixed in following patches). Since we're touching them anyway, we change get() and set() to take a const struct kernel_param (which they really are). This causes some harmless warnings until we fix them (in following patches). To reduce churn, module_param_call creates the ops struct so the callers don't have to change (and casts the functions to reduce warnings). The modern version which takes an ops struct is called module_param_cb.

2010-07-06sunrpc: make the cache cleaner workqueue deferrableArtem Bityutskiy2-1/+7
This patch makes the cache_cleaner workqueue deferrable, to prevent unnecessary system wake-ups, which is very important for embedded battery-powered devices. do_cache_clean() is called every 30 seconds at the moment, and often makes the system wake up from its power-save sleep state. With this change, when the workqueue uses a deferrable timer, the do_cache_clean() invocation will be delayed and combined with the closest "real" wake-up. This improves the power consumption situation. Note, I tried to create a DECLARE_DELAYED_WORK_DEFERRABLE() helper macro, similar to DECLARE_DELAYED_WORK(), but failed because of the way the timer wheel core stores the deferrable flag (it is the LSBit in the time->base pointer). My attempt to define a static variable with this bit set ended up with the "initializer element is not constant" error. Thus, I have to use run-time initialization, so I created a new cache_initialize() function which is called once when sunrpc is being initialized.

2010-05-17net: Remove unnecessary returns from void function()sJoe Perches4-7/+0
This patch removes from net/ (but not any netfilter files) all the unnecessary return; statements that precede the last closing brace of void functions. It does not remove the returns that are immediately preceded by a label as gcc doesn't like that. Done via: $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \ xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }' Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-05-17sunrpc: Include missing smp_lock.hFrederic Weisbecker1-0/+1
Now that cache_ioctl_procfs() calls the bkl explicitly, we need to include the relevant header as well. This fixes the following build error: net/sunrpc/cache.c: In function 'cache_ioctl_procfs': net/sunrpc/cache.c:1355: error: implicit declaration of function 'lock_kernel' net/sunrpc/cache.c:1359: error: implicit declaration of function 'unlock_kernel' Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com>
2010-05-17procfs: Push down the bkl from ioctlFrederic Weisbecker1-4/+10
Push down the bkl from procfs's ioctl main handler to its users. Only three procfs users implement an ioctl (non unlocked) handler. Turn them into unlocked_ioctl and push down the Devil inside. v2: PDE(inode)->data doesn't need to be under bkl v3: And don't forget to git-add the result v4: Use wrappers to pushdown instead of an invasive and error prone handlers surgery.

2010-05-14SUNRPC: Don't spam gssd with upcall requests when the kerberos key expiredTrond Myklebust1-12/+53
Now that the rpc.gssd daemon can explicitly tell us that the key expired, we should cache that information to avoid spamming gssd. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2010-05-14SUNRPC: Remove the 'tk_magic' debugging fieldTrond Myklebust1-11/+0
It has not triggered in almost a decade. Time to get rid of it... Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
2010-05-14SUNRPC: Move the task->tk_bytes_sent and tk_rtt to struct rpc_rqstTrond Myklebust4-7/+7
It seems strange to maintain stats for bytes_sent in one structure, and bytes received in another. Try to assemble all the RPC request-related stats in struct rpc_rqst Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
