d5791d1 Linus Torvalds 09 June 2008, 17:06:24 UTC Fix invalid access errors in blk_lookup_devt Commit 30f2f0eb4bd2c43d10a8b0d872c6e5ad8f31c9a0 ("block: do_mounts - accept root=<non-existant partition>") extended blk_lookup_devt() to be able to look up partitions that had not yet been registered, but in the process made the assumption that the '&block_class.devices' list only contains disk devices and that you can do 'dev_to_disk(dev)' on them. That isn't actually true. The block_class device list also contains the partitions we've discovered so far, and you can't just do a 'dev_to_disk()' on those. So make sure to only work on devices that block/genhd.c has registered itself, something we can test by checking the 'dev->type' member. This makes the loop in blk_lookup_devt() match the other such loops in this file. [ We may want to do an alternate version that knows to handle _either_ whole-disk devices or partitions, but for now this is the minimal fix for a series of crashes reported by Mariusz Kozlowski in http://lkml.org/lkml/2008/5/25/25 and Ingo in http://lkml.org/lkml/2008/6/9/39 ] Reported-by: Mariusz Kozlowski <m.kozlowski@tuxland.pl> Reported-by: Ingo Molnar <mingo@elte.hu> Cc: Neil Brown <neilb@suse.de> Cc: Joao Luis Meloni Assirati <assirati@nonada.if.usp.br> Acked-by: Kay Sievers <kay.sievers@vrfy.org> Cc: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 09 June 2008, 17:06:24 UTC
4c0283f Roland Dreier 09 June 2008, 16:58:42 UTC IB/core: Remove IB_DEVICE_SEND_W_INV capability flag In 2.6.26, we added some support for send with invalidate work requests, including a device capability flag to indicate whether a device supports such requests. However, the support was incomplete: the completion structure was not extended with a field for the key contained in incoming send with invalidate requests. Full support for memory management extensions (send with invalidate, local invalidate, fast register through a send queue, etc) is planned for 2.6.27. Since send with invalidate is not very useful by itself, just remove the IB_DEVICE_SEND_W_INV bit before the 2.6.26 final release; we will add an IB_DEVICE_MEM_MGT_EXTENSIONS bit in 2.6.27, which makes things simpler for applications, since they will not have quite as confusing an array of fine-grained bits to check.

8079ffa Roland Dreier 07 June 2008, 04:38:37 UTC IB/umem: Avoid sign problems when demoting npages to integer On a 64-bit architecture, if ib_umem_get() is called with a size value that is so big that npages is negative when cast to int, then the length of the page list passed to get_user_pages(), namely min_t(int, npages, PAGE_SIZE / sizeof (struct page *)) will be negative, and get_user_pages() will immediately return 0 (at least since 900cf086, "Be more robust about bad arguments in get_user_pages()"). This leads to an infinite loop in ib_umem_get(), since the code boils down to: while (npages) { ret = get_user_pages(...); npages -= ret; } Fix this by taking the minimum as unsigned longs, so that the value of npages is never truncated. The impact of this bug isn't too severe, since the value of npages is checked against RLIMIT_MEMLOCK, so a process would need to have an astronomical limit or have CAP_IPC_LOCK to be able to trigger this, and such a process could already cause lots of mischief. But it does let buggy userspace code cause a kernel lock-up; for example I hit this with code that passes a negative value into a memory registartion function where it is promoted to a huge u64 value.

Since I figure that there will be more people reading this kernel-doc-nano-HOWTO.txt file who are kernel developers focused on the rest of the kernel, than there will be readers of this file who are documentation developers extracting that embedded kernel-doc documentation, I have taken the liberty of making the new section added here: How to format kernel-doc comments the first section of the kernel-doc-nano-HOWTO.txt file. This first section is intended to introduce, motivate and provide basic usage of the kernel-doc mechanism for kernel hackers developing other portions of the kernel.

9c81c5c Haavard Skinnemoen 06 June 2008, 05:46:39 UTC atmel_serial: filter out FP during baud rate detection I made a change to u-boot that used the FP (Fractional Part) field of BRGR to achieve more accurate baud rate generation. Unfortunately, the atmel_serial driver looks at the whole BRGR register when trying to detect the baud rate that the port is currently running at, so setting FP to a nonzero value breaks the baud rate detection. I'll sit on the u-boot patch for a while longer, but this is clearly a bug in the atmel_serial driver which should be fixed.

In http://lkml.org/lkml/2008/4/29/575 Tony Luck complained that this message references an ipc namespace address that is useless. I first thought of using an audit_log instead of a printk, as suggested by Serge Hallyn. But unfortunately, we do not have any other information than the namespace address to provide here too. So I chose to move the message and output it only at boot time, removing the reference to the namespace.

Previously, since pm->out was a char *, put_user was only copying 1 byte of every PFN, resulting in the top 7 bytes of each PFN not being copied. By requiring that reads be a multiple of 8 bytes, I can make pm->out and pm->end u64*s instead of char*s, which makes put_user work properly, and also simplifies the logic in add_to_pagemap a bit.

d1ee297 Pavel Emelyanov 06 June 2008, 05:46:28 UTC devscgroup: make white list more compact in some cases Consider you added a 'c foo:bar r' permission to some cgroup and then (a bit later) 'c'foo:bar w' for it. After this you'll see the c foo:bar r c foo:bar w lines in a devices.list file. Another example - consider you added 10 'c foo:bar r' permissions to some cgroup (e.g. by mistake). After this you'll see 10 c foo:bar r lines in a list file. This is weird. This situation also has one more annoying consequence. Having many items in a white list makes permissions checking slower, sine it has to walk a longer list. The proposal is to merge permissions for items, that correspond to the same device.

cc9cb21 Pavel Emelyanov 06 June 2008, 05:46:26 UTC devscgroup: relax task to dev_cgroup conversion Two functions, that need to get a device_cgroup from a task (they are devcgroup_inode_permission and devcgroup_inode_mknod) make it in a strange way: They get a css_set from task, then a subsys_state from css_set, then a cgroup from the state and then a subsys_state again from the cgroup. Besides, the devices_subsys_id is read from memory, whilst there's a enum-ed constant for it. Optimize this part a bit: 1. Get the subsys_stats form the task and be done - no 2 extra dereferences, 2. Use the device_subsys_id constant, not the value from memory (i.e. one less dereference). Found while preparing 2.6.26 OpenVZ port.
