2009-03-22ucc_geth: Fix oops when using fixed-link supportAnton Vorontsov
commit b1c4a9dddf09fe99b8f88252718ac5b357363dc4 ("ucc_geth: Change uec phy id to the same format as gianfar's") introduced a regression in the ucc_geth driver that causes this oops when fixed-link is used: Unable to handle kernel paging request for data at address 0x00000000 Faulting instruction address: 0xc0151270 Oops: Kernel access of bad area, sig: 11 [#1] TMCUTU NIP: c0151270 LR: c0151270 CTR: c0017760 REGS: cf81fa60 TRAP: 0300 Not tainted (2.6.29-rc8) MSR: 00009032 <EE,ME,IR,DR> CR: 24024042 XER: 20000000 DAR: 00000000, DSISR: 20000000 TASK = cf81cba0[1] 'swapper' THREAD: cf81e000 GPR00: c0151270 cf81fb10 cf81cba0 00000000 c0272e20 c025f354 00001e80 cf86b08c GPR08: d1068200 cffffb74 06000000 d106c200 42024042 10085148 0fffd000 0ffc81a0 GPR16: 00000001 00000001 00000000 007ffeb0 00000000 0000c000 cf83f36c cf83f000 GPR24: 00000030 cf83f360 cf81fb20 00000000 d106c200 20000000 00001e80 cf83f360 NIP [c0151270] ucc_geth_open+0x330/0x1efc LR [c0151270] ucc_geth_open+0x330/0x1efc Call Trace: [cf81fb10] [c0151270] ucc_geth_open+0x330/0x1efc (unreliable) [cf81fba0] [c0187638] dev_open+0xbc/0x12c [cf81fbc0] [c0187e38] dev_change_flags+0x8c/0x1b0 This patch fixes the issue by removing offending (and somewhat duplicate) code from init_phy() routine, and changes _probe() function to use uec_mdio_bus_name(). Also, since we fully construct phy_bus_id in the _probe() routine, we no longer need ->phy_address and ->mdio_bus fields in ucc_geth_info structure. I wish the patch would be a bit shorter, but it seems like the only way to fix the issue in a sane way. Luckily, the patch has been tested with real PHYs and fixed-link, so no further regressions expected.

2009-03-22dm9000: locking bugfixDavid Brownell
This fixes a locking bug in the dm9000 driver. It calls request_irq() without setting IRQF_DISABLED ... which is correct for handlers that support IRQ sharing, since that behavior is not guaranteed for shared IRQs. However, its IRQ handler then wrongly assumes that IRQs are blocked. So the fix just uses the right spinlock primitives in the IRQ handler. NOTE: this is a classic example of the type of bug which lockdep currently masks by forcibly setting IRQF_DISABLED on IRQ handlers that did not request that flag.

2009-03-22eCryptfs: NULL crypt_stat dereference during lookupTyler Hicks
If ecryptfs_encrypted_view or ecryptfs_xattr_metadata were being specified as mount options, a NULL pointer dereference of crypt_stat was possible during lookup. This patch moves the crypt_stat assignment into ecryptfs_lookup_and_interpose_lower(), ensuring that crypt_stat will not be NULL before we attempt to dereference it. Thanks to Dan Carpenter and his static analysis tool, smatch, for finding this bug.

2009-03-22eCryptfs: Allocate a variable number of pages for file headersTyler Hicks
When allocating the memory used to store the eCryptfs header contents, a single, zeroed page was being allocated with get_zeroed_page(). However, the size of an eCryptfs header is either PAGE_CACHE_SIZE or ECRYPTFS_MINIMUM_HEADER_EXTENT_SIZE (8192), whichever is larger, and is stored in the file's private_data->crypt_stat->num_header_bytes_at_front field. ecryptfs_write_metadata_to_contents() was using num_header_bytes_at_front to decide how many bytes should be written to the lower filesystem for the file header. Unfortunately, at least 8K was being written from the page, despite the chance of the single, zeroed page being smaller than 8K. This resulted in random areas of kernel memory being written between the 0x1000 and 0x1FFF bytes offsets in the eCryptfs file headers if PAGE_SIZE was 4K. This patch allocates a variable number of pages, calculated with num_header_bytes_at_front, and passes the number of allocated pages along to ecryptfs_write_metadata_to_contents(). Thanks to Florian Streibelt for reporting the data leak and working with me to find the problem. 2.6.28 is the only kernel release with this vulnerability.

2009-03-22radeonfb: Whack the PCI PM register until it sticksBenjamin Herrenschmidt
This fixes a regression introduced when we switched to using the core pci_set_power_state(). The chip seems to need the state to be written over and over again until it sticks, so we do that. Note that the code is a bit blunt, without timeout, etc... but that's pretty much because I put back in there the code exactly as it used to be before the regression. I still add a call to pci_set_power_state() at the end so that ACPI gets called appropriately on x86.

2009-03-19aio: lookup_ioctx can return the wrong value when looking up a bogus contextJeff Moyer
The libaio test harness turned up a problem whereby lookup_ioctx on a bogus io context was returning the 1 valid io context from the list (harness/cases/3.p). Because of that, an extra put_iocontext was done, and when the process exited, it hit a BUG_ON in the put_iocontext macro called from exit_aio (since we expect a users count of 1 and instead get 0). The problem was introduced by "aio: make the lookup_ioctx() lockless" (commit abf137dd7712132ee56d5b3143c2ff61a72a5faa). Thanks to Zach for pointing out that hlist_for_each_entry_rcu will not return with a NULL tpos at the end of the loop, even if the entry was not found.

2009-03-19eventfd: remove fput() call from possible IRQ contextDavide Libenzi
Remove a source of fput() call from inside IRQ context. Myself, like Eric, wasn't able to reproduce an fput() call from IRQ context, but Jeff said he was able to, with the attached test program. Independently from this, the bug is conceptually there, so we might be better off fixing it. This patch adds an optimization similar to the one we already do on ->ki_filp, on ->ki_eventfd. Playing with ->f_count directly is not pretty in general, but the alternative here would be to add a brand new delayed fput() infrastructure, that I'm not sure is worth it.

2009-03-19Fix race in create_empty_buffers() vs __set_page_dirty_buffers()Linus Torvalds
Nick Piggin noticed this (very unlikely) race between setting a page dirty and creating the buffers for it - we need to hold the mapping private_lock until we've set the page dirty bit in order to make sure that create_empty_buffers() might not build up a set of buffers without the dirty bits set when the page is dirty. I doubt anybody has ever hit this race (and it didn't solve the issue Nick was looking at), but as Nick says: "Still, it does appear to solve a real race, which we should close."

This makes sure that gcc doesn't try to optimize away wrapping arithmetic, which the kernel occasionally uses for overflow testing, ie things like if (ptr + offset < ptr) which technically is undefined for non-unsigned types. See http://bugzilla.kernel.org/show_bug.cgi?id=12597 for details. Not all versions of gcc support it, so we need to make it conditional (it looks like it was introduced in gcc-3.4).

2009-03-18sparc64: Fix crash with /proc/iomemMikulas Patocka
When you compile kernel on Sparc64 with heap memory checking and type "cat /proc/iomem", you get a crash, because pointers in struct resource are uninitialized. Most code fills struct resource with zeros, so I assume that it is responsibility of the caller of request_resource to initialized it, not the responsibility of request_resource functuion. After 2.6.29 is out, there could be a check for uninitialized fields added to request_resource to avoid crashes like this. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: David S.

2009-03-18smsc911x: reset last known duplex and carrier on openSteve Glendinning
smsc911x_phy_adjust_link is called periodically by the phy layer (as it's run in polling mode), and it only updates the hardware when it sees a change in duplex or carrier. This patch clears the last known values every time the interface is brought up, instead of only when the module is loaded. Without this patch the adjust_link function never updates the hardware after an ifconfig down; ifconfig up. On a full duplex link this causes the tx error counter to increment, even though packets are correctly transmitted, as the default MAC_CR register setting is for half duplex. The tx errors are "no carrier" errors, which should be ignored in full-duplex mode. When MAC_CR is set to "full duplex" mode they are correctly ignored by the hardware. Note that even with this patch the tx error counter can increment if packets are transmitted between "ifconfig up" and the first phy poll interval. An improved solution would use the phy interrupt with phylib, but I haven't managed to make this work 100% robustly yet.

2009-03-18[S390] make page table upgrade work againMartin Schwidefsky
After TASK_SIZE now gives the current size of the address space the upgrade of a 64 bit process from 3 to 4 levels of page table needs to use the arch_mmap_check hook to catch large mmap lengths. The get_unmapped_area* functions need to check for -ENOMEM from the arch_get_unmapped_area*, upgrade the page table and retry. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
2009-03-18[S390] make page table walking more robustMartin Schwidefsky
Make page table walking on s390 more robust. The current code requires that the pgd/pud/pmd/pte loop is only done for address ranges that are below the end address of the last vma of the address space. But this is not always true, e.g. the generic page table walker does not guarantee this. Change TASK_SIZE/TASK_SIZE_OF to reflect the current size of the address space. This makes the generic page table walker happy but it breaks the upgrade of a 3 level page table to a 4 level page table. To make the upgrade work again another fix is required.

2009-03-18[S390] Dont check for pfn_valid() in uaccess_pt.cGerald Schaefer
pfn_valid() actually checks for a valid struct page and not for a valid pfn. Using xip mappings w/o struct pages, this will result in -EFAULT returned by the (page table walk) user copy functions, even though there is valid memory. Those user copy functions don't need a struct page, so this patch just removes the pfn_valid() check.
