由 Anatolij Gustschin 提交于
Currently while submitting scatterlists with more than one SG entry the DMA buffer address from the first SG entry is inserted into all initialized DMA buffer descriptors. This is due to the typo in the for_each_sg() loop where the scatterlist pointer is used for obtaining the DMA buffer address and _not_ the SG list iterator. As a result all received data will be written only into the first DMA buffer while reading. While writing the data from the first DMA buffer is send to the device multiple times. This caused the filesystem destruction on the MMC card when using DMA in mxcmmc driver.

This reverts commit e0fdace1. On-list discussion seems to suggest that the robustness fixes for printk make this unnecessary and DaveM has also agreed in person at Kernel Summit and on list. The main problem with this code is once we hit a lockdep splat we always keep oops_in_progress set, the console layer uses oops_in_progress with KMS to decide when it should be showing the oops and not showing X, so it causes problems around suspend/resume time when a userspace resume can cause a console switch away from X, only if oops_in_progress is set (which is what we want if an oops actually is in progress, but not because we had a lockdep splat 2 days prior).

Some Lenovos have TPMs that require a quirk to function correctly. This can be autodetected by checking whether the device has a _HID of INTC0102. This is an invalid PNPid, and as such is discarded by the pnp layer - however it's still present in the ACPI code, so we can pull it out that way. This means that the quirk won't be automatically applied on non-ACPI systems, but without ACPI we don't have any way to identify the chip anyway so I don't think that's a great concern.

由 Eric Dumazet 提交于
Its easy to eat all kernel memory and trigger NMI watchdog, using an exploit program that queues unix sockets on top of others. lkml ref : http://lkml.org/lkml/2010/11/25/8 This mechanism is used in applications, one choice we have is to have a recursion limit. Other limits might be needed as well (if we queue other types of files), since the passfd mechanism is currently limited by socket receive queue sizes only. Add a recursion_level to unix socket, allowing up to 4 levels. Each time we send an unix socket through sendfd mechanism, we copy its recursion level (plus one) to receiver. This recursion level is cleared when socket receive queue is emptied.

In commit 58933c64(ucc_geth: Fix the wrong the Rx/Tx FIFO size), the UCC_GETH_UTFTT_INIT is set to 512 based on the recommendation of the QE Reference Manual. But that will sometimes cause tx halt while working in half duplex mode. According to errata draft QE_GENERAL-A003(High Tx Virtual FIFO threshold size can cause UCC to halt), setting UTFTT less than [(UTFS x (M - 8)/M) - 128] will prevent this from happening (M is the minimum buffer size). The patch changes UTFTT back to 256.

由 Nagendra Tomar 提交于
inet sockets corresponding to passive connections are added to the bind hash using ___inet_inherit_port(). These sockets are later removed from the bind hash using __inet_put_port(). These two functions are not exactly symmetrical. __inet_put_port() decrements hashinfo->bsockets and tb->num_owners, whereas ___inet_inherit_port() does not increment them. This results in both of these going to -ve values. This patch fixes this by calling inet_bind_hash() from ___inet_inherit_port(), which does the right thing.

And in particular, use it in 'pipe_fcntl()'. The other pipe functions do not need to use the 'careful' version, since they are only ever called for things that are already known to be pipes. The normal read/write/ioctl functions are called through the file operations structures, so if a file isn't a pipe, they'd never get called. But pipe_fcntl() is special, and called directly from the generic fcntl code, and needs to use the same careful function that the splice code is using.

.. and change it to take the 'file' pointer instead of an inode, since that's what all users want anyway. The renaming is preparatory to exporting it to other users. The old 'pipe_info()' name was too generic and is already used elsewhere, so before making the function public we need to use a more specific name.
