2009-12-21mac80211: fix peer HT capabilitiesJohannes Berg
I noticed yesterday, because Jeff had noticed a speed regression, cf. bug http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2138 that the SM PS settings for peers were wrong. Instead of overwriting the SM PS settings with the local bits, we need to keep the remote bits. The bug was part of the original HT code from over two years ago, but unfortunately nobody noticed that it makes no sense -- we shouldn't be overwriting the peer's setting with our own but rather keep it intact when masking the peer capabilities with our own. While fixing that, I noticed that the masking of capabilities is completely useless for most of the bits, so also fix those other bits. Finally, I also noticed that PSMP_SUPPORT no longer exists in the final 802.11n version, so also remove that. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

2009-12-14mac80211: Add define for TX headroom reserved by mac80211 itself.Gertjan van Wingerde
Add a definition of the amount of TX headroom reserved by mac80211 itself for its own purposes. Also add BUILD_BUG_ON to validate the value. This define can then be used by drivers to request additional TX headroom in the most efficient manner.

2009-12-09tcp: Stalling connections: Fix timeout calculation routineDamian Lukowski
This patch fixes a problem in the TCP connection timeout calculation. Currently, timeout decisions are made on the basis of the current tcp_time_stamp and retrans_stamp, which is usually set at the first retransmission. However, if the retransmission fails in tcp_retransmit_skb(), retrans_stamp is not updated and remains zero. This leads to wrong decisions in retransmits_timed_out() if tcp_time_stamp is larger than the specified timeout, which is very likely. In this case, the TCP connection dies after the first attempted (and unsuccessful) retransmission. With this patch, tcp_skb_cb->when is used instead, when retrans_stamp is not available. This bug has been introduced together with retransmits_timed_out() in 2.6.32, as the number of retransmissions has been used for timeout decisions before. The corresponding commit was 6fa12c85031485dff38ce550c24f10da23b0adaa (Revert Backoff [v3]: Calculate TCP's connection close threshold as a time value.). Thanks to Ilpo Järvinen for code suggestions and Frederic Leroy for testing.

2009-12-09tcp: Fix a connect() race with timewait socketsEric Dumazet
When we find a timewait connection in __inet_hash_connect() and reuse it for a new connection request, we have a race window, releasing bind list lock and reacquiring it in __inet_twsk_kill() to remove timewait socket from list. Another thread might find the timewait socket we already chose, leading to list corruption and crashes. Fix is to remove timewait socket from bind list before releasing the bind lock. Note: This problem happens if sysctl_tcp_tw_reuse is set. Reported-by: kapil dakhane <kdakhane@gmail.com> Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2009-12-09tcp: Fix a connect() race with timewait socketsEric Dumazet
First patch changes __inet_hash_nolisten() and __inet6_hash() to get a timewait parameter to be able to unhash it from ehash at same time the new socket is inserted in hash.

2009-12-06i2c: Drop probe, ignore and force module parametersJean Delvare
The legacy probe and force module parameters are obsolete now, the same can be achieved using the new_device sysfs interface, which is both more flexible and cheaper (it is implemented by i2c-core rather than replicated in every driver module.) The legacy ignore module parameters can be dropped as well. Ignoring can be done by instantiating a "dummy" device at the problematic address. This is the first step of a huge cleanup to i2c-core's i2c_detect function, i2c.h's I2C_CLIENT_INSMOD* macros, and all drivers that made use of them. Signed-off-by: Jean Delvare <khali@linux-fr.org>

2009-12-05Add support for GCC-4.5's __builtin_unreachable() to compiler.h (v2)David Daney
Starting with version 4.5, GCC has a new built-in function __builtin_unreachable() that can be used in places like the kernel's BUG() where inline assembly is used to transfer control flow. This eliminated the need for an endless loop in these places. The patch adds a new macro 'unreachable()' that will expand to either __builtin_unreachable() or an endless loop depending on the compiler version. Change from v1: Simplify unreachable() for non-GCC 4.5 case.

2009-12-04block: Fix io_context leak after failure of clone with CLONE_IOLouis Rilling
With CLONE_IO, parent's io_context->nr_tasks is incremented, but never decremented whenever copy_process() fails afterwards, which prevents exit_io_context() from calling IO schedulers exit functions. Give a task_struct to exit_io_context(), and call exit_io_context() instead of put_io_context() in copy_process() cleanup path.
