8db14ca Steve French 23 May 2009, 18:57:25 UTC [CIFS] Avoid open on possible directories since Samba now rejects them Small change (mostly formatting) to limit lookup based open calls to file create only. After discussion yesteday on samba-technical about the posix lookup regression, and looking at a problem with cifs posix open to one particular Samba version, Jeff and JRA realized that Samba server's behavior changed in this area (posix open behavior on files vs. directories). To make this behavior consistent, JRA just made a fix to Samba server to alter how it handles open of directories (now returning the equivalent of EISDIR instead of success). Since we don't know at lookup time whether the inode is a directory or file (and thus whether posix open will succeed with most current Samba server), this change avoids the posix open code on lookup open (just issues posix open on creates). This gets the semantic benefits we want (atomicity, posix byte range locks, improved write semantics on newly created files) and file create still is fast, and we avoid the problem that Jeff noticed yesterday with "openat" (and some open directory calls) of non-cached directories to one version of Samba server, and will work with future Samba versions (which include the fix jra just pushed into Samba server). I confirmed this approach with jra yesterday and with Shirish today. Posix open is only called (at lookup time) for file create now. For opens (rather than creates), because we do not know if it is a file or directory yet, and current Samba no longer allows us to do posix open on dirs, we could end up wasting an open call on what turns out to be a dir. For file opens, we wait to call posix open till cifs_open. It could be added here (lookup) in the future but the performance tradeoff of the extra network request when EISDIR or EACCES is returned would have to be weighed against the 50% reduction in network traffic in the other paths.

b674137 Benjamin Herrenschmidt 18 May 2009, 01:56:16 UTC drm: Round size of SHM maps to PAGE_SIZE Currently, userspace can fail to obtain the SAREA mapping (among other reasons) if it passes SAREA_MAX to drmAddMap without aligning it to the page size. This breaks for example on PowerPC with 64K pages and radeon despite the kernel radeon actually doing the right rouding in the first place. The way SAREA_MAX is defined with a bunch of ifdef's and duplicated between libdrm and the X server is gross, ultimately it should be retrieved by userspace from the kernel, but in the meantime, we have plenty of existing userspace built with bad values that need to work. This patch works around broken userspace by rounding the requested size in drm_addmap_core() of any SHM map to the page size. Since the backing memory for SHM maps is also allocated within addmap_core, there is no danger of adjacent memory being exposed due to the increased map size. The only side effect is that drivers that previously tried to create or access SHM maps using a size < PAGE_SIZE and failed (getting -EINVAL), will now succeed at the cost of a little bit more memory used if that happens to be when the map is created.

What the code doesn't take into account is that sprintf(buf, "%02x", data) actually writes 3 bytes. 2 bytes for the data and then it nul terminates the string. Since we declare buf to be 40 characters long and then we write 40 bytes of data into buf sprintf is going to write 41 characters. The fix is to leave room in buf for the nul terminator.

b3bad72 Rafael J. Wysocki 17 May 2009, 18:17:06 UTC PCI PM: Fix initialization and kexec breakage for some devices Recent PCI PM changes introduced a bug that causes some devices to be mishandled after kexec and during early initialization. The failure scenario in the kexec case is the following: * Assume a PCI device is not power-manageable by the platform and has PCI_PM_CTRL_NO_SOFT_RESET set in PMCSR. * The device is put into D3 before kexec (using the native PCI PM). * After kexec, pci_setup_device() sets the device's power state to PCI_UNKNOWN. * pci_set_power_state(dev, PCI_D0) is called by the device's driver. * __pci_start_power_transition(dev, PCI_D0) is called and since the device is not power-manageable by the platform, it causes pci_update_current_state(dev, PCI_D0) to be called. As a result the device's current_state field is updated to PCI_D3, in accordance with the contents of its PCI PM registers. * pci_raw_set_power_state() is called and it changes the device power state to D0. *However*, it should also call pci_restore_bars() to reinitialize the device, but it doesn't, because the device's current_state field has been modified earlier. To prevent this from happening, modify pci_platform_power_transition() so that it doesn't use pci_update_current_state() to update the current_state field for devices that aren't power-manageable by the platform. Instead, this field should be updated directly for devices that don't support the native PCI PM. Signed-off-by: Rafael J.

64d1304 Thomas Gleixner 18 May 2009, 19:20:10 UTC futex: setup writeable mapping for futex ops which modify user space data The futex code installs a read only mapping via get_user_pages_fast() even if the futex op function has to modify user space data. The eventual fault was fixed up by futex_handle_fault() which walked the VMA with mmap_sem held. After the cleanup patches which removed the mmap_sem dependency of the futex code commit 4dc5b7a36a49eff97050894cf1b3a9a02523717 (futex: clean up fault logic) removed the private VMA walk logic from the futex code. This change results in a stale RO mapping which is not fixed up. Instead of reintroducing the previous fault logic we set up the mapping in get_user_pages_fast() read/write for all operations which modify user space data. Also handle private futexes in the same way and make the current unconditional access_ok(VERIFY_WRITE) depend on the futex op.

8b6427a Jeff Layton 19 May 2009, 13:57:03 UTC cifs: fix pointer initialization and checks in cifs_follow_symlink (try #4) This is the third respin of the patch posted yesterday to fix the error handling in cifs_follow_symlink. It also includes a fix for a bogus NULL pointer check in CIFSSMBQueryUnixSymLink that Jeff Moyer spotted. It's possible for CIFSSMBQueryUnixSymLink to return without setting target_path to a valid pointer. If that happens then the current value to which we're initializing this pointer could cause an oops when it's kfree'd. This patch is a little more comprehensive than the last patches. It reorganizes cifs_follow_link a bit for (hopefully) better readability. It should also eliminate the uneeded allocation of full_path on servers without unix extensions (assuming they can get to this point anyway, of which I'm not convinced). On a side note, I'm not sure I agree with the logic of enabling this query even when unix extensions are disabled on the client. It seems like that should disable this as well. But, changing that is outside the scope of this fix, so I've left it alone for now.

8019319 David Woodhouse 18 May 2009, 12:07:35 UTC Fix oops on close of hot-unplugged FTDI serial converter Commit c45d6320 ("fix reference counting of ftdi_private") stopped ftdi_sio_port_remove() from directly freeing the port-private data, with the intention if the port was still open, it would be freed when ftdi_close() is eventually called and releases the last refcount on the structure. That's all very well, but ftdi_sio_port_remove() still contains a call to usb_set_serial_port_data(port, NULL) -- so by the time we get to ftdi_close() for the port which was unplugged, it _still_ oopses on dereferencing that NULL pointer, as it did before (and does in 2.6.29). The fix is just not to clear the private data in ftdi_sio_port_remove(). Then the refcount is properly reduced to zero when the final kref_put() happens in ftdi_close(). Remove a bogus comment too, while we're at it. And stop doing things inside "if (priv)" -- it must _always_ be there. Based loosely on an earlier patch by Daniel Mack, and suggestions by Alan Stern.

eb33575 Mel Gorman 13 May 2009, 16:34:48 UTC [ARM] Double check memmap is actually valid with a memmap has unexpected holes V2 pfn_valid() is meant to be able to tell if a given PFN has valid memmap associated with it or not. In FLATMEM, it is expected that holes always have valid memmap as long as there is valid PFNs either side of the hole. In SPARSEMEM, it is assumed that a valid section has a memmap for the entire section. However, ARM and maybe other embedded architectures in the future free memmap backing holes to save memory on the assumption the memmap is never used. The page_zone linkages are then broken even though pfn_valid() returns true. A walker of the full memmap must then do this additional check to ensure the memmap they are looking at is sane by making sure the zone and PFN linkages are still valid. This is expensive, but walkers of the full memmap are extremely rare. This was caught before for FLATMEM and hacked around but it hits again for SPARSEMEM because the page_zone linkages can look ok where the PFN linkages are totally screwed. This looks like a hatchet job but the reality is that any clean solution would end up consumning all the memory saved by punching these unexpected holes in the memmap. For example, we tried marking the memmap within the section invalid but the section size exceeds the size of the hole in most cases so pfn_valid() starts returning false where valid memmap exists. Shrinking the size of the section would increase memory consumption offsetting the gains. This patch identifies when an architecture is punching unexpected holes in the memmap that the memory model cannot automatically detect and sets ARCH_HAS_HOLES_MEMORYMODEL. At the moment, this is restricted to EP93xx which is the model sub-architecture this has been reported on but may expand later. When set, walkers of the full memmap must call memmap_valid_within() for each PFN and passing in what it expects the page and zone to be for that PFN. If it finds the linkages to be broken, it assumes the memmap is invalid for that PFN.

This was discovered on my x86 boxes. The issue is that gcc used the same register for an output as it did for an input in an asm statement. I first thought this was a bug in gcc and reported it. I was notified that gcc was correct and that the output had to be flagged as an "early clobber". I noticed that powerpc had the same issue and this patch fixes it.

If all the members of a bonded device have no carrier present, the bonded device itself needs to report no carrier present to user space so management tools (like routing daemons) can respond. Bonding in 802.3ad mode does not work correctly for this because it incorrectly chooses a link that is down as a possible aggregator.

2513dfb Chris Friesen 18 May 2009, 03:39:33 UTC ipconfig: handle case of delayed DHCP server If a DHCP server is delayed, it's possible for the client to receive the DHCPOFFER after it has already sent out a new DHCPDISCOVER message from a second interface. The client then sends out a DHCPREQUEST from the second interface, but the server doesn't recognize the device and rejects the request. This patch simply tracks the current device being configured and throws away the OFFER if it is not intended for the current device. A more sophisticated approach would be to put the OFFER information into the struct ic_device rather than storing it globally.
