2013-02-28hlist: drop the node parameter from iteratorsSasha Levin
I'm not sure why, but the hlist for each entry iterators were conceived list_for_each_entry(pos, head, member) The hlist ones were greedy and wanted an extra parameter: hlist_for_each_entry(tpos, pos, head, member) Why did they need an extra pos parameter? I'm not quite sure. Not only they don't really need it, it also prevents the iterator from looking exactly like the list iterator, which is unfortunate. Besides the semantic patch, there was some manual work required: - Fix up the actual hlist iterators in linux/list.h - Fix up the declaration of other iterators based on the hlist ones. - A very small amount of places were using the 'node' parameter, this was modified to use 'obj->member' instead. - Coccinelle didn't handle the hlist_for_each_entry_safe iterator properly, so those had to be fixed up manually. The semantic patch which is mostly the work of Peter Senna Tschudin is here: @@ iterator name hlist_for_each_entry, hlist_for_each_entry_continue, hlist_for_each_entry_from, hlist_for_each_entry_rcu, hlist_for_each_entry_rcu_bh, hlist_for_each_entry_continue_rcu_bh, for_each_busy_worker, ax25_uid_for_each, ax25_for_each, inet_bind_bucket_for_each, sctp_for_each_hentry, sk_for_each, sk_for_each_rcu, sk_for_each_from, sk_for_each_safe, sk_for_each_bound, hlist_for_each_entry_safe, hlist_for_each_entry_continue_rcu, nr_neigh_for_each, nr_neigh_for_each_safe, nr_node_for_each, nr_node_for_each_safe, for_each_gfn_indirect_valid_sp, for_each_gfn_sp, for_each_host; type T; expression a,c,d,e; identifier b; statement S; @@ -T b; <+... when != b ( hlist_for_each_entry(a, - b, c, d) S | hlist_for_each_entry_continue(a, - b, c) S | hlist_for_each_entry_from(a, - b, c) S | hlist_for_each_entry_rcu(a, - b, c, d) S | hlist_for_each_entry_rcu_bh(a, - b, c, d) S | hlist_for_each_entry_continue_rcu_bh(a, - b, c) S | for_each_busy_worker(a, c, - b, d) S | ax25_uid_for_each(a, - b, c) S | ax25_for_each(a, - b, c) S | inet_bind_bucket_for_each(a, - b, c) S | sctp_for_each_hentry(a, - b, c) S | sk_for_each(a, - b, c) S | sk_for_each_rcu(a, - b, c) S | sk_for_each_from -(a, b) +(a) S + sk_for_each_from(a) S | sk_for_each_safe(a, - b, c, d) S | sk_for_each_bound(a, - b, c) S | hlist_for_each_entry_safe(a, - b, c, d, e) S | hlist_for_each_entry_continue_rcu(a, - b, c) S | nr_neigh_for_each(a, - b, c) S | nr_neigh_for_each_safe(a, - b, c, d) S | nr_node_for_each(a, - b, c) S | nr_node_for_each_safe(a, - b, c, d) S | - for_each_gfn_sp(a, c, d, b) S + for_each_gfn_sp(a, c, d) S | - for_each_gfn_indirect_valid_sp(a, c, d, b) S + for_each_gfn_indirect_valid_sp(a, c, d) S | for_each_host(a, - b, c) S | for_each_host_safe(a, - b, c, d) S | for_each_mesh_entry(a, - b, c, d) S ) ...+> [akpm@linux-foundation.org: drop bogus change from net/ipv4/raw.c] [akpm@linux-foundation.org: drop bogus hunk from net/ipv6/raw.c] [akpm@linux-foundation.org: checkpatch fixes] [akpm@linux-foundation.org: fix warnings] [akpm@linux-foudnation.org: redo intrusive kvm changes] Tested-by: Peter Senna Tschudin <peter.senna@gmail.com> Acked-by: Paul E.

2011-02-07x25: possible skb leak on bad facilitiesandrew hendry
Originally x25_parse_facilities returned -1 for an error 0 meaning 0 length facilities >0 the length of the facilities parsed. 5ef41308f94dc ("x25: Prevent crashing when parsing bad X.25 facilities") introduced more error checking in x25_parse_facilities however used 0 to indicate bad parsing a6331d6f9a429 ("memory corruption in X.25 facilities parsing") followed this further for DTE facilities, again using 0 for bad parsing. The meaning of 0 got confused in the callers. If the facilities are messed up we can't determine where the data starts.

2010-10-21BKL: introduce CONFIG_BKL.Arnd Bergmann
With all the patches we have queued in the BKL removal tree, only a few dozen modules are left that actually rely on the BKL, and even there are lots of low-hanging fruit. We need to decide what to do about them, this patch illustrates one of the options: Every user of the BKL is marked as 'depends on BKL' in Kconfig, and the CONFIG_BKL becomes a user-visible option. If it gets disabled, no BKL using module can be built any more and the BKL code itself is compiled out. The one exception is file locking, which is practically always enabled and does a 'select BKL' instead. This effectively forces CONFIG_BKL to be enabled until we have solved the fs/lockd mess and can apply the patch that removes the BKL from fs/locks.c. Signed-off-by: Arnd Bergmann <arnd@arndb.de>

V2 Feedback from John Hughes. - Add header for userspace implementations such as xot/xoe to use - Use explicit values for interface stability - No changes to driver patches V1 - Use identifiers instead of magic numbers for X25 layer 3 to device interface. - Also fixed checkpatch notes on updated code.

2010-04-21X25 fix dead unaccepted socketsandrew hendry
1, An X25 program binds and listens 2, calls arrive waiting to be accepted 3, Program exits without accepting 4, Sockets time out but don't get correctly cleaned up 5, cat /proc/net/x25/socket shows the dead sockets with bad inode fields. This line borrowed from AX25 sets the dying socket so the timers clean up later. Signed-off-by: Andrew Hendry <andrew.hendry@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Define a new function to return the waitqueue of a "struct sock". static inline wait_queue_head_t *sk_sleep(struct sock *sk) { return sk->sk_sleep; } Change all read occurrences of sk_sleep by a call to this function. Needed for a future RCU conversion. sk_sleep wont be a field directly available. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-04-08x.25 attempts to negotiate invalid throughputJohn Hughes
The current X.25 code has some bugs in throughput negotiation: 1. It does negotiation in all cases, usually there is no need 2. It incorrectly attempts to negotiate the throughput class in one direction only. There are separate throughput classes for input and output and if either is negotiated both mist be negotiates. This is bug https://bugzilla.kernel.org/show_bug.cgi?id=15681 This bug was first reported by Daniel Ferenci to the linux-x25 mailing list on 6/8/2004, but is still present. The current (2.6.34) x.25 code doesn't seem to know that the X.25 throughput facility includes two values, one for the required throughput outbound, one for inbound. This causes it to attempt to negotiate throughput 0x0A, which is throughput 9600 inbound and the illegal value "0" for inbound throughput. Because of this some X.25 devices (e.g. Cisco 1600) refuse to connect to Linux X.25. The following patch fixes this behaviour. Unless the user specifies a required throughput it does not attempt to negotiate. If the user does not specify a throughput it accepts the suggestion of the remote X.25 system. If the user requests a throughput then it validates both the input and output throughputs and correctly negotiates them with the remote end.
