commit 438957f8 upstream. Interrupts must be disabled prior to calling usb_hcd_unlink_urb_from_ep. If interrupts are not disabled, it can potentially lead to a deadlock. The deadlock is readily reproduceable on a slower (ARM based) device such as the TI Pandaboard. Signed-off-by:

This one liner is part of upstream commit 3701e513 Author: Jesse Gross <jesse@nicira.com> vlan: Centralize handling of hardware acceleration. The bulk of that commit is a rework of the hardware assisted vlan tagging driver interface, and as such doesn't classify for -stable inclusion. The fix that is needed is a part of that commit but can work independently of the rest. This patch can avoid panics on the 2.6.32.y -stable kernels and is in the same spirit as mainline commits 66c46d74 gro: Reset dev pointer on reuse 6d152e23 gro: reset skb_iif on reuse which are already in -stable. For drivers using the vlan_gro_frags() interface, a packet with an invalid tci leads to GRO_DROP and napi_reuse_skb(). The skb has to be sanitized before being reused or we may send an skb with an invalid vlan_tci field up the stack where it is not expected. Signed-off-by:

commit 2d161817 upstream. priv->work must not be synced while priv->mutex is locked, because the mutex is taken in the work handler. Move cancel_work_sync down to after the device shutdown code. This is safe, because the work handler checks fw_state and bails out early in case of a race. Signed-off-by:

commit d004e024 upstream. ktime_get and ktime_get_ts were calling timekeeping_get_ns() but later they were not calling arch_gettimeoffset() so architectures using this mechanism returned 0 ns when calling these functions. This happened for example when running Busybox's ping which calls syscall(__NR_clock_gettime, CLOCK_MONOTONIC, ts) which eventually calls ktime_get. As a result the returned ping travel time was zero. Signed-off-by:

commit 24ca9a84 upstream. By returning '0' instead of 'EAGAIN' when the tests in xs_nospace() fail to find evidence of socket congestion, we are making the RPC engine believe that the message was incorrectly sent and so it disconnects the socket instead of just retrying. The bug appears to have been introduced by commit 5e3771ce (SUNRPC: Ensure that xs_nospace return values are propagated). Reported-by:

commit a2987855 upstream. commit 6175ddf0 optimized the mem*io functions that have been used to send commands to the device. these optimizations somehow corrupted the communication with the lx6464es, that resulted the device to be unusable with kernels after 2.6.33. this patch emulates the memcpy_*_io functions via a loop to avoid these problems.

Will Deacon authored
commit 11ed0ba1 upstream. This patch implements a workaround for PL310 erratum 769419. On revisions of the PL310 prior to r3p2, the Store Buffer does not automatically drain. This can cause normal, non-cacheable writes to be retained when the memory system is idle, leading to suboptimal I/O performance for drivers using coherent DMA. This patch adds an optional wmb() call to the cpu_idle loop. On systems with an outer cache, this causes an explicit flush of the store buffer. Acked-by:

commit 4cac2eb1 upstream. Previously we claimed device ID 0x7450, regardless of the vendor, which is clearly wrong. Now we'll claim that device ID only for AMD. I suspect this was just a typo in the original code, but it's possible this change will break shpchp on non-7450 AMD bridges. If so, we'll have to fix them as we find them.

commit 0f751e64 upstream. From mhalcrow's original commit message: Characters with ASCII values greater than the size of filename_rev_map[] are valid filename characters. ecryptfs_decode_from_filename() will access kernel memory beyond that array, and ecryptfs_parse_tag_70_packet() will then decrypt those characters. The attacker, using the FNEK of the crafted file, can then re-encrypt the characters to reveal the kernel memory past the end of the filename_rev_map[] array. I expect low security impact since this array is statically allocated in the text area, and the amount of memory past the array that is accessible is limited by the largest possible ASCII filename character. This patch solves the issue reported by mhalcrow but with an implementation suggested by Linus to simply extend the length of filename_rev_map[] to 256. Characters greater than 0x7A are mapped to 0x00, which is how invalid characters less than 0x7A were previously being handled. Signed-off-by:

commit 2f640bf4 upstream. The 8020i protocol (also 8070i and QIC-157) uses 12-byte commands; shorter commands must be padded. Simon Detheridge reports that his 3-TB USB disk drive claims to use the 8020i protocol (which is normally meant for ATAPI devices like CD drives), and because of its large size, the disk drive requires the use of 16-byte commands. However the usb_stor_pad12_command() routine in usb-storage always sets the command length to 12, making the drive impossible to use. Since the SFF-8020i specification allows for 16-byte commands in future extensions, we may as well accept them. This patch (as1490) changes usb_stor_pad12_command() to leave commands larger than 12 bytes alone rather than truncating them. Signed-off-by:

commit b1ffb4c8 upstream. Fix for ftdi_set_termios() glitching output ftdi_set_termios() is constantly setting the baud rate, data bits and parity unnecessarily on every call, . When called while characters are being transmitted can cause the FTDI chip to corrupt the serial port bit stream output by stalling the output half a bit during the output of a character. Simple fix by skipping this setting if the baud rate/data bits/parity are unchanged. Signed-off-by:

commit 0c165955 upstream. I get report from customer that his usb-serial converter doesn't work well,it sometimes work, but sometimes it doesn't. The usb-serial converter's id: vendor_id product_id 0x4348 0x5523 Then I search the usb-serial codes, and there are two drivers announce support this device, pl2303 and ch341, commit 026dfaf1 cause it. Through many times to test, ch341 works well with this device, and pl2303 doesn't work quite often(it just work quite little). ch341 works well with this device, so we doesn't need pl2303 to support.I try to revert 026dfaf1 first, but it failed. So I prepare this patch by hand to revert it. Signed-off-by:

commit 8417da6f upstream. Starting with 4.4, gcc will happily accept -Wno-<anything> in the cc-option test and complain later when compiling a file that has some other warning. This rather unexpected behavior is intentional as per http://gcc.gnu.org/PR28322, so work around it by testing for support of the opposite option (without the no-). Introduce a new Makefile function cc-disable-warning that does this and update two uses of cc-option in the toplevel Makefile. Reported-and-tested-by:

commit a9cf73ea upstream. At this point, skb->data points to skb_transport_header. So, headroom check is wrong. For some case:bridge(UFO is on) + eth device(UFO is off), there is no enough headroom for IPv6 frag head. But headroom check is always false. This will bring about data be moved to there prior to skb->head, when adding IPv6 frag header to skb. Signed-off-by:

commit f5252e00 upstream The /proc/vmallocinfo shows information about vmalloc allocations in vmlist that is a linklist of vm_struct. It, however, may access pages field of vm_struct where a page was not allocated. This results in a null pointer access and leads to a kernel panic. Why this happen: In __vmalloc_node() called from vmalloc(), newly allocated vm_struct is added to vmlist at __get_vm_area_node() and then, some fields of vm_struct such as nr_pages and pages are set at __vmalloc_area_node(). In other words, it is added to vmlist before it is fully initialized. At the same time, when the /proc/vmallocinfo is read, it accesses the pages field of vm_struct according to the nr_pages field at show_numa_info(). Thus, a null pointer access happens. Patch: This patch adds newly allocated vm_struct to the vmlist *after* it is fully initialized. So, it can avoid accessing the pages field with unallocated page when show_numa_info() is called.

commit 9bab0b7f upstream This adds a mechanism to resume selected IRQs during syscore_resume instead of dpm_resume_noirq. Under Xen we need to resume IRQs associated with IPIs early enough that the resched IPI is unmasked and we can therefore schedule ourselves out of the stop_machine where the suspend/resume takes place. This issue was introduced by 676dc3cf "xen: Use IRQF_FORCE_RESUME". Back ported to 2.6.32 (which lacks syscore support) by calling the relavant resume function directly from sysdev_resume). v2: Fixed non-x86 build errors. Signed-off-by:

commit c30bc947 upstream. L2TP for example uses NLA_MSECS like this: policy: [L2TP_ATTR_RECV_TIMEOUT] = { .type = NLA_MSECS, }, code: if (info->attrs[L2TP_ATTR_RECV_TIMEOUT]) cfg.reorder_timeout = nla_get_msecs(info->attrs[L2TP_ATTR_RECV_TIMEOUT]); As nla_get_msecs() is essentially nla_get_u64() plus the conversion to a HZ-based value, this will not properly reject attributes from userspace that aren't long enough and might overrun the message. Add NLA_MSECS to the attribute minlen array to check the size properly. Cc: Thomas Graf <tgraf@suug.ch> Signed-off-by:
