[S390] fix futex_atomic_cmpxchg_inatomic futex_atomic_cmpxchg_inatomic has the same bug as the other atomic futex operations: the operation needs to be done in the user address space, not the kernel address space. Add the missing sacf 256 & sacf 0. Signed-off-by:

Currently I am doing lots of refactoring work in the dvb tree. This bugfix became necessary to fix 2.6.17 whilst I was in the middle of this work. Unfortunately after I tested the original code for the patch, I generated the diff against the wrong tree (I accidentally used a tree with part of the refactoring code in it). This resulted in the reported compile errors because that tree (a) was incomplete, and (b) used features which are simply not in the mainline kernel yet. Many apologies for the error and problems this has caused. :( Signed-off-by:

Fix a bug identified by Zou Nan hai <nanhai.zou@intel.com>: If the system is in state SYSTEM_BOOTING, and need_resched() is true, cond_resched() returns true even though it didn't reschedule. Consequently need_resched() remains true and JBD locks up. Fix that by teaching cond_resched() to only return true if it really did call schedule(). cond_resched_lock() and cond_resched_softirq() have a problem too. If we're in SYSTEM_BOOTING state and need_resched() is true, these functions will drop the lock and will then try to call schedule(), but the SYSTEM_BOOTING state will prevent schedule() from being called. So on return, need_resched() will still be true, but cond_resched_lock() has to return 1 to tell the caller that the lock was dropped. The caller will probably lock up. Bottom line: if these functions dropped the lock, they _must_ call schedule() to clear need_resched(). Make it so. Also, uninline __cond_resched(). It's largeish, and slowpath. Acked-by:

The inode number out of an NFS file handle gets passed eventually to ext3_get_inode_block() without any checking. If ext3_get_inode_block() allows it to trigger an error, then bad filehandles can have unpleasant effect - ext3_error() will usually cause a forced read-only remount, or a panic if `errors=panic' was used. So remove the call to ext3_error there and put a matching check in ext3/namei.c where inode numbers are read off storage. [akpm@osdl.org: fix off-by-one error] Signed-off-by:

Fix race related problem when adding items to and svcrpc auth cache. If we don't find the item we are lookng for, we allocate a new one, and then grab the lock again and search to see if it has been added while we did the alloc. If it had been added we need to 'cache_put' the newly created item that we are never going to use. But as it hasn't been initialised properly, putting it can cause an oops. So move the ->init call earlier to that it will always be fully initilised if we have to put it. Thanks to Philipp Matthias Hahn <pmhahn@svs.Informatik.Uni-Oldenburg.de> for reporting the problem.

[NET]: Update frag_list in pskb_trim When pskb_trim has to defer to ___pksb_trim to trim the frag_list part of the packet, the frag_list is not updated to reflect the trimming. This will usually work fine until you hit something that uses the packet length or tail from the frag_list. Examples include esp_output and ip_fragment. Another problem caused by this is that you can end up with a linear packet with a frag_list attached. It is possible to get away with this if we audit everything to make sure that they always consult skb->len before going down onto frag_list. In fact we can do the samething for the paged part as well to avoid copying the data area of the skb. For now though, let's do the conservative fix and update frag_list. Many thanks to Marco Berizzi for helping me to track down this bug. This 4-year old bug took 3 months to track down. Marco was very patient indeed :) Signed-off-by:

This patch (as753) fixes the way uhci-hcd handles a short packet when it is the last packet of an URB. Right now the driver handles short packets the same no matter when they occur. However, the controller stops transferring packets when the short packet is not the last one (otherwise it would be reading beyond the end of the device's data) and needs to be restarted, whereas no such need occurs when the short packet is the last one. The result of the bug is that USB endpoint queues experience intermittent hangs, a regression in 2.6.17 with respect to earlier kernels. The bug was raised in Bugzilla #6752 and this patch fixed it.

The scx200_acb i2c bus driver pretends to support SMBus block transactions, but in fact it implements the more simple I2C block transactions. Additionally, it lacks sanity checks on the length of the block transactions, which could lead to a buffer overrun.

Don't allow chmod() on the /proc/<pid>/ files This just turns off chmod() on the /proc/<pid>/ files, since there is no good reason to allow it, and had we disallowed it originally, the nasty /proc race exploit wouldn't have been possible. The other patches already fixed the problem chmod() could cause, so this is really just some final mop-up.. This particular version is based off a patch by Eugene and Marcel which had much better naming than my original equivalent one. Signed-off-by:

According to Petr Vandrovec: ... "What is important (and checked) is address of MMCONFIG reported by MCFG table... Unfortunately code does not bother with printing that address :-( "Another problem is that code has hardcoded that MMCONFIG area is 256MB large. Unfortunately for the code PCI specification allows any power of two between 2MB and 256MB if vendor knows that such amount of busses (from 2 to 128) will be sufficient for system. With notebook it is quite possible that not full 8 bits are implemented for MMCONFIG bus number." So here is a patch. Unfortunately my system still fails the test because it doesn't reserve any part of the MMCONFIG area, but this may fix others. Booted on x86_64, only compiled on i386. x86_64 still remaps the max area (256MB) even though only 2MB is checked... but 2.6.16 had no check at all so it is still better. PCI: reduce size of x86 MMCONFIG reserved area check 1. Print the address of the MMCONFIG area when the test for that area being reserved fails. 2. Only check if the first 2MB is reserved, as that is the minimum. Signed-off-by:Chuck Ebbert <76306.1226@compuserve.com> Acked-by:

2.6.16 leaks like hell. While testing, I found massive leakage (reproduced in openvz) in: *filp *size-4096 And 1 object leaks in *size-32 *size-64 *size-128 It is the fix for the first one. filp leaks in the bowels of namei.c. Seems, size-4096 is file table leaking in expand_fdtables. I have no idea what are the rest and why they show only accompanying another leaks. Some debugging structs?

2.6.16 needs this. It was merged into 2.6.18-rc1 in http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=d616e09ab33aa4d013a93c9b393efd5cebf78521 . pdflush is carefully designed to ensure that all wakeups have some corresponding work to do - if a woken-up pdflush thread discovers that it hasn't been given any work to do then this is considered an error. That all broke when swsusp came along - because a timer-delivered wakeup to a frozen pdflush thread will just get lost. This causes the pdflush thread to get lost as well: the writeback timer is supposed to be re-armed by pdflush in process context, but pdflush doesn't execute the callout which does this. Fix that up by ignoring the return value from try_to_freeze(): jsut proceed, see if we have any work pending and only go back to sleep if that is not the case. Signed-off-by:

This bug was unknowingly fixed the GSO patches (or rather, its effect was unknown at the time). Thanks to Marco Berizzi's persistence which is documented in the thread "ipsec tunnel asymmetrical mtu", we now know that it can have highly non-obvious symptoms. What happens is that uninitialised uso_size fields can cause packets to be incorrectly identified as UFO, which means that it does not get fragmented even if it's over the MTU. The fix is simple enough. Signed-off-by:

The recent generic_file_write() deadlock fix caused generic_file_buffered_write() to loop inifinitely when presented with a zero-length iovec segment. Fix. Note that this fix deliberately avoids calling ->prepare_write(), ->commit_write() etc with a zero-length write. This is because I don't trust all filesystems to get that right. This is a cautious approach, for 2.6.17.x. For 2.6.18 we should just go ahead and call ->prepare_write() and ->commit_write() with the zero length and fix any broken filesystems. So I'll make that change once this code is stabilised and backported into 2.6.17.x. The reason for preferring to call ->prepare_write() and ->commit_write() with the zero-length segment: a zero-length segment _should_ be sufficiently uncommon that this is the correct way of handling it. We don't want to optimise for poorly-written userspace at the expense of well-written userspace. Cc: "Vladimir V.
