2012-01-25tcp: bind() fix autoselection to share portsFlavio Leitner
The current code checks for conflicts when the application requests a specific port. If there is no conflict, then the request is granted. On the other hand, the port autoselection done by the kernel fails when all ports are bound even when there is a port with no conflict available. The fix changes port autoselection to check if there is a conflict and use it if not.

2012-01-25l2tp: l2tp_ip - fix possible oops on packet receiveJames Chapman
When a packet is received on an L2TP IP socket (L2TPv3 IP link encapsulation), the l2tpip socket's backlog_rcv function calls xfrm4_policy_check(). This is not necessary, since it was called before the skb was added to the backlog. With CONFIG_NET_NS enabled, xfrm4_policy_check() will oops if skb->dev is null, so this trivial patch removes the call. This bug has always been present, but only when CONFIG_NET_NS is enabled does it cause problems. Most users are probably using UDP encapsulation for L2TP, hence the problem has only recently surfaced.

2012-01-24rds: Make rds_sock_lock BH rather than IRQ safe.David S. Miller
rds_sock_info() triggers locking warnings because we try to perform a local_bh_enable() (via sock_i_ino()) while hardware interrupts are disabled (via taking rds_sock_lock). There is no reason for rds_sock_lock to be a hardware IRQ disabling lock, none of these access paths run in hardware interrupt context. Therefore making it a BH disabling lock is safe and sufficient to fix this bug. Reported-by: Kumar Sanghvi <kumaras@chelsio.com> Reported-by: Josh Boyer <jwboyer@gmail.com> Signed-off-by: David S.

2012-01-23ALSA: hda - Fix silent outputs from docking-station jacks of Dell laptopsTakashi Iwai
The recent change of the power-widget handling for IDT codecs caused the silent output from the docking-station line-out jack. This was partially fixed by the commit f2cbba7602383cd9cdd21f0a5d0b8bd1aad47b33 "ALSA: hda - Fix the lost power-setup of seconary pins after PM resume". But the line-out on the docking-station is still silent when booted with the jack plugged even by this fix. The remainig bug is that the power-widget is set off in stac92xx_init() because the pins in cfg->line_out_pins[] aren't checked there properly but only hp_pins[] are checked in is_nid_hp_pin(). This patch fixes the problem by checking both HP and line-out pins and leaving the power-map correctly.

include/net/cfg80211.h uses __must_check in functions that have kernel-doc notation. This was confusing scripts/kernel-doc, so have scripts/kernel-doc ignore "__must_check".

2012-01-23score: fix off-by-one index into syscall tableDan Rosenberg
If the provided system call number is equal to __NR_syscalls, the current check will pass and a function pointer just after the system call table may be called, since sys_call_table is an array with total size __NR_syscalls. Whether or not this is a security bug depends on what the compiler puts immediately after the system call table. It's likely that this won't do anything bad because there is an additional NULL check on the syscall entry, but if there happens to be a non-NULL value immediately after the system call table, this may result in local privilege escalation.
