This follows the ARM change c0177800 ("ARM: 6379/1: Assume new page cache pages have dirty D-cache") for the same rationale: There are places in Linux where writes to newly allocated page cache pages happen without a subsequent call to flush_dcache_page() (several PIO drivers including USB HCD). This patch changes the meaning of PG_arch_1 to be PG_dcache_clean and always flush the D-cache for a newly mapped page in update_mmu_cache(). This addresses issues seen with executing binaries from MMC, in addition to some of the other HCDs that don't explicitly do cache management for their pipe-in buffers. Requested-by:

Note: this patch targets 2.6.37 and tries to be as simple as possible. That is why it adds more copy-and-paste horror into fs/compat.c and uglifies fs/exec.c, this will be cleanuped later. compat_copy_strings() plays with bprm->vma/mm directly and thus has two problems: it lacks the RLIMIT_STACK check and argv/envp memory is not visible to oom killer. Export acct_arg_size() and get_arg_page(), change compat_copy_strings() to use get_arg_page(), change compat_do_execve() to do acct_arg_size(0) as do_execve() does. Add the fatal_signal_pending/cond_resched checks into compat_count() and compat_copy_strings(), this matches the code in fs/exec.c and certainly makes sense. Signed-off-by:

Brad Spengler published a local memory-allocation DoS that evades the OOM-killer (though not the virtual memory RLIMIT): http://www.grsecurity.net/~spender/64bit_dos.c execve()->copy_strings() can allocate a lot of memory, but this is not visible to oom-killer, nobody can see the nascent bprm->mm and take it into account. With this patch get_arg_page() increments current's MM_ANONPAGES counter every time we allocate the new page for argv/envp. When do_execve() succeds or fails, we change this counter back. Technically this is not 100% correct, we can't know if the new page is swapped out and turn MM_ANONPAGES into MM_SWAPENTS, but I don't think this really matters and everything becomes correct once exec changes ->mm or fails.

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.

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. Reported-by:

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. Signed-off-by:

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. 'bsockets' and 'num_owners' were introduced by commit a9d8f911 (inet: Allowing more than 64k connections and heavily optimize bind(0)) Signed-off-by:

The new DIO bio splitting code has problems when the bio spans more than one ordered extent. This will happen as the generic DIO code merges our get_blocks calls together into a bigger single bio.

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.
