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.

generic_file_buffered_write() prefaults in user pages in order to avoid deadlock on copying from the same page as write goes to. However, it looks like there is a problem when write is vectored: fault_in_pages_readable brings in current segment or its part (maxlen). OTOH, filemap_copy_from_user_iovec is called to copy number of bytes (bytes) which may exceed current segment, so filemap_copy_from_user_iovec switches to the next segment which is not brought in yet. Pagefault is generated. That causes the deadlock if pagefault is for the same page write goes to: page being written is locked and not uptodate, pagefault will deadlock trying to lock locked page.

Ian Abbott authored
This patch limits the amount of outstanding 'write' data that can be queued up for the ftdi_sio driver, to prevent userspace DoS attacks (or simple accidents) that use up all the system memory by writing lots of data to the serial port. The original patch was by Guillaume Autran, who in turn based it on the same mechanism implemented in the 'visor' driver. I (Ian Abbott) re-targeted the patch to the latest sources, fixed a couple of errors, renamed his new structure members, and updated the implementations of the 'write_room' and 'chars_in_buffer' methods to take account of the number of outstanding 'write' bytes. It seems to work fine, though at low baud rates it is still possible to queue up an amount of data that takes an age to shift (a job for another day!). Signed-off-by:

Several issues noticed/fixed: - We cannot reliably block in link_pipe() while holding both input and output mutexes. So do preparatory checks before locking down both mutexes and doing the link. - The ipipe->nrbufs vs i check was bad, because we could have dropped the ipipe lock in-between. This causes us to potentially look at unknown buffers if we were racing with someone else reading this pipe. Signed-off-by:

[CPUFREQ] Make powernow-k7 work on SMP kernels. Even though powernow-k7 doesn't work in SMP environments, it can work on an SMP configured kernel if there's only one CPU present, however recalibrate_cpu_khz was returning -EINVAL on such kernels, so we failed to init the cpufreq driver.

"return -err" and blindly inheriting the error code in the netlink failure exception handler causes errors codes to be returned as positive value therefore making them being ignored by the caller. May lead to sending out incomplete netlink messages. Signed-off-by:

Thomas Graf authored
The TCA_ACT_KIND attribute is used without checking its availability when dumping actions therefore leading to a value of 0x4 being dereferenced. The use of strcmp() in tc_lookup_action_n() isn't safe when fed with string from an attribute without enforcing proper NUL termination. Both bugs can be triggered with malformed netlink message and don't require any privileges. Signed-off-by:

As detailed at http://bugs.gentoo.org/131534 : 2.6.16 converted many ACPI debug messages into error or warning messages. One extraneous message was incorrectly converted, resulting in logs being flooded by "Handle is NULL and Pathname is relative" messages on some systems. This patch (part of a larger ACPICA commit) converts the message back to debug level. Signed-off-by:

Memory hotplug code of i386 adds memory to only highmem. So, if CONFIG_HIGHMEM is not set, CONFIG_MEMORY_HOTPLUG shouldn't be set. Otherwise, it causes compile error. In addition, many architecture can't use memory hotplug feature yet. So, I introduce CONFIG_ARCH_ENABLE_MEMORY_HOTPLUG. Signed-off-by:

Fix nused counter. It's currently getting set to -1 rather than getting decremented by 1. Since nused never reaches 0, the "if (!free->hdr.nused)" check in xfs_dir2_leafn_remove() fails every time and xfs_dir2_shrink_inode() doesn't get called when it should. This causes extra blocks to be left on an empty directory and the directory in unable to be converted back to inline extent mode. Signed-off-by:

Fix nasty /proc vulnerability We have a bad interaction with both the kernel and user space being able to change some of the /proc file status. This fixes the most obvious part of it, but I expect we'll also make it harder for users to modify even their "own" files in /proc. Signed-off-by:

Based on a patch from Ernie Petrides During security research, Red Hat discovered a behavioral flaw in core dump handling. A local user could create a program that would cause a core file to be dumped into a directory they would not normally have permissions to write to. This could lead to a denial of service (disk consumption), or allow the local user to gain root privileges. Signed-off-by:
