2012-09-20tcp: restore rcv_wscale in a repair mode (v2)Andrey Vagin
rcv_wscale is a symetric parameter with snd_wscale. Both this parameters are set on a connection handshake. Without this value a remote window size can not be interpreted correctly, because a value from a packet should be shifted on rcv_wscale. And one more thing is that wscale_ok should be set too. This patch doesn't break a backward compatibility. If someone uses it in a old scheme, a rcv window will be restored with the same bug (rcv_wscale = 0). v2: Save backward compatibility on big-endian system. Before the first two bytes were snd_wscale and the second two bytes were rcv_wscale. Now snd_wscale is opt_val & 0xFFFF and rcv_wscale >> 16. This approach is independent on byte ordering.

2012-09-19pkt_sched: fix virtual-start-time update in QFQPaolo Valente
If the old timestamps of a class, say cl, are stale when the class becomes active, then QFQ may assign to cl a much higher start time than the maximum value allowed. This may happen when QFQ assigns to the start time of cl the finish time of a group whose classes are characterized by a higher value of the ratio max_class_pkt/weight_of_the_class with respect to that of cl. Inserting a class with a too high start time into the bucket list corrupts the data structure and may eventually lead to crashes. This patch limits the maximum start time assigned to a class.

2012-09-19tcp: flush DMA queue before sk_wait_data if rcv_wnd is zeroMichal Kubeček
If recv() syscall is called for a TCP socket so that - IOAT DMA is used - MSG_WAITALL flag is used - requested length is bigger than sk_rcvbuf - enough data has already arrived to bring rcv_wnd to zero then when tcp_recvmsg() gets to calling sk_wait_data(), receive window can be still zero while sk_async_wait_queue exhausts enough space to keep it zero. As this queue isn't cleaned until the tcp_service_net_dma() call, sk_wait_data() cannot receive any data and blocks forever. If zero receive window and non-empty sk_async_wait_queue is detected before calling sk_wait_data(), process the queue first. Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Signed-off-by: David S.

2012-09-19batman-adv: make batadv_test_bit() return 0 or 1 onlyLinus Lüssing
On some architectures test_bit() can return other values than 0 or 1: With a generic x86 OpenWrt image in a kvm setup (batadv_)test_bit() frequently returns -1 for me, leading to batadv_iv_ogm_update_seqnos() wrongly signaling a protected seqno window. This patch tries to fix this issue by making batadv_test_bit() return 0 or 1 only.

Stephan Springl found that commit 1402d366019fed "tcp: introduce tcp_try_coalesce" introduced a regression for rlogin It turns out problem comes from TCP urgent data handling and a change in behavior in input path. rlogin sends two one-byte packets with URG ptr set, and when next data frame is coalesced, we lack sk_data_ready() calls to wakeup consumer.

Commit d6cb3e41 "bnx2x: fix checksum validation" caused a performance regression for IPv6. Rx checksum offload does not work. IPv6 packets are passed to the stack with CHECKSUM_NONE. The hardware obviously cannot perform IP checksum validation for IPv6, because there is no checksum in the IPv6 header. This should not prevent us from setting CHECKSUM_UNNECESSARY.

IPv6 dst should take care of rt_genid too. When a xfrm policy is inserted or deleted, all dst should be invalidated. To force the validation, dst entries should be created with ->obsolete set to DST_OBSOLETE_FORCE_CHK. This was already the case for all functions calling ip6_dst_alloc(), except for ip6_rt_copy().

Arend van Spriel sends a simple thinko fix to correct a constant, preventing the setting of an invalid power level. Colin Ian King gives us a simple allocation failure check to avoid a NULL pointer dereference. Felix Fietkau sends another ath9k tx power patch, this time disabling a feature that has been reported to cause rx problems. Hante Meuleman provides a pair of endian fixes for brcmfmac. Larry Finger offers an rtlwifi fix that avoids a system lockup related to loading the wrong firmware for RTL8188CE devices.

2012-09-14vfs: make O_PATH file descriptors usable for 'fstat()'Linus Torvalds
We already use them for openat() and friends, but fstat() also wants to be able to use O_PATH file descriptors. This should make it more directly comparable to the O_SEARCH of Solaris. Note that you could already do the same thing with "fstatat()" and an empty path, but just doing "fstat()" directly is simpler and faster, so there is no reason not to just allow it directly. See also commit 332a2e1244bd, which did the same thing for fchdir, for the same reasons.

2012-09-14eCryptfs: Copy up attributes of the lower target inode after renameTyler Hicks
After calling into the lower filesystem to do a rename, the lower target inode's attributes were not copied up to the eCryptfs target inode. This resulted in the eCryptfs target inode staying around, rather than being evicted, because i_nlink was not updated for the eCryptfs inode. This also meant that eCryptfs didn't do the final iput() on the lower target inode so it stayed around, as well. This would result in a failure to free up space occupied by the target file in the rename() operation. Both target inodes would eventually be evicted when the eCryptfs filesystem was unmounted. This patch calls fsstack_copy_attr_all() after the lower filesystem does its ->rename() so that important inode attributes, such as i_nlink, are updated at the eCryptfs layer. ecryptfs_evict_inode() is now called and eCryptfs can drop its final reference on the lower inode. http://launchpad.net/bugs/561129 Signed-off-by: Tyler Hicks <tyhicks@canonical.com> Tested-by: Colin Ian King <colin.king@canonical.com> Cc: <stable@vger.kernel.org> [2.6.39+]
2012-09-14eCryptfs: Call lower ->flush() from ecryptfs_flush()Tyler Hicks
Since eCryptfs only calls fput() on the lower file in ecryptfs_release(), eCryptfs should call the lower filesystem's ->flush() from ecryptfs_flush(). If the lower filesystem implements ->flush(), then eCryptfs should try to flush out any dirty pages prior to calling the lower ->flush(). If the lower filesystem does not implement ->flush(), then eCryptfs has no need to do anything in ecryptfs_flush() since dirty pages are now written out to the lower filesystem in ecryptfs_release().

2012-09-14eCryptfs: Write out all dirty pages just before releasing the lower fileTyler Hicks
Fixes a regression caused by: 821f749 eCryptfs: Revert to a writethrough cache model That patch reverted some code (specifically, 32001d6f) that was necessary to properly handle open() -> mmap() -> close() -> dirty pages -> munmap(), because the lower file could be closed before the dirty pages are written out. Rather than reapplying 32001d6f, this approach is a better way of ensuring that the lower file is still open in order to handle writing out the dirty pages. It is called from ecryptfs_release(), while we have a lock on the lower file pointer, just before the lower file gets the final fput() and we overwrite the pointer. https://launchpad.net/bugs/1047261 Signed-off-by: Tyler Hicks <tyhicks@canonical.com> Reported-by: Artemy Tregubenko <me@arty.name> Tested-by: Artemy Tregubenko <me@arty.name> Tested-by: Colin Ian King <colin.king@canonical.com>

The code currently always selects turbo mode for PCA9665, no matter which clock frequency is configured. This is because it compares the clock frequency against constants reflecting (boundary / 100).
