commit 093ea2d3 upstream. A MCS7820 device supports two serial ports and a MCS7840 device supports four serial ports. Both devices use the same driver, but the attach function in driver was unable to correctly handle the port numbers for MCS7820 device. This problem has been fixed in this patch and this fix has been verified on x86 Linux kernel 3.2.9 with both MCS7820 and MCS7840 devices. Signed-off-by:

commit a5360a53 upstream. This patch updates the cp210x driver to support CP210x multiple interface devices devices from Silicon Labs. The existing driver always sends control requests to interface 0, which is hardcoded in the usb_control_msg function calls. This only allows for single interface devices to be used, and causes a bug when using ports on an interface other than 0 in the multiple interface devices. Here are the changes included in this patch: - Updated the device list to contain the Silicon Labs factory default VID/PID for multiple interface CP210x devices - Created a cp210x_port_private struct created for each port on startup, this struct holds the interface number - Added a cp210x_release function to clean up the cp210x_port_private memory created on startup - Modified usb_get_config and usb_set_config to get a pointer to the cp210x_port_private struct, and use the interface number there in the usb_control_message wIndex param Signed-off-by:

commit c192c8e7 upstream. Gobi 1000 devices have a different port layout, which wasn't respected by the current driver, and thus it grabbed the QMI/net port. In the near future we'll be attaching another driver to the QMI/net port for these devices (cdc-wdm and qmi_wwan) so make sure the qcserial driver doesn't claim them. This patch also prevents qcserial from binding to interfaces 0 and 1 on 1K devices because those interfaces do not respond. Signed-off-by:

commit 4898e071 upstream. __do_config_autodelink passes the data variable to the transport function. If the calling functions pass a stack variable, this will eventually trigger a DMA-API debug backtrace for mapping stack memory in the DMA buffer. Fix this by calling kmemdup for the passed data instead. Signed-off-by:

commit e90fc3cb upstream. When build i.mx platform with imx_v6_v7_defconfig, and after adding USB Gadget support, it has below build error: CC drivers/usb/host/fsl-mph-dr-of.o drivers/usb/host/fsl-mph-dr-of.c: In function 'fsl_usb2_device_register': drivers/usb/host/fsl-mph-dr-of.c:97: error: 'struct pdev_archdata' has no member named 'dma_mask' It has discussed at: http://www.spinics.net/lists/linux-usb/msg57302.html For PowerPC, there is dma_mask at struct pdev_archdata, but there is no dma_mask at struct pdev_archdata for ARM. The pdev_archdata is related to specific platform, it should NOT be accessed by cross platform drivers, like USB. The code for pdev_archdata should be useless, as for PowerPC, it has already gotten the value for pdev->dev.dma_mask at function arch_setup_pdev_archdata of arch/powerpc/kernel/setup-common.c.

commit 711c68b3 upstream. We must not allow the input buffer length to change while we're shuffling the buffer contents. We also mustn't clear the WDM_READ flag after more data might have arrived. Therefore move both of these into the spinlocked region at the bottom of wdm_read(). When reading desc->length without holding the iuspin lock, use ACCESS_ONCE() to ensure the compiler doesn't re-read it with inconsistent results. Signed-off-by:

commit 4a4c61b7 upstream. Bugzilla 40012: PIO_UNIMAP bug: error updating Unicode-to-font map https://bugzilla.kernel.org/show_bug.cgi?id=40012 The unicode font map for the virtual console is a 32x32x64 table which allocates rows dynamically as entries are added. The unicode value increases sequentially and should count all entries even in empty rows. The defect is when copying the unicode font map in con_set_unimap(), the unicode value is not incremented properly. The wrong unicode value is entered in the new font map. Signed-off-by:

commit 93518dd2 upstream. This patch fixies follwing two memory leak patterns that reported by kmemleak. sysfs_sd_setsecdata() is called during sys_lsetxattr() operation. It checks sd->s_iattr is NULL or not. Then if it is NULL, it calls sysfs_init_inode_attrs() to allocate memory. That code is this. iattrs = sd->s_iattr; if (!iattrs) iattrs = sysfs_init_inode_attrs(sd); The iattrs recieves sysfs_init_inode_attrs()'s result, but sd->s_iattr doesn't know the address. so it needs to set correct address to sd->s_iattr to free memory in other function. unreferenced object 0xffff880250b73e60 (size 32): comm "systemd", pid 1, jiffies 4294683888 (age 94.553s) hex dump (first 32 bytes): 73 79 73 74 65 6d 5f 75 3a 6f 62 6a 65 63 74 5f system_u:object_ 72 3a 73 79 73 66 73 5f 74 3a 73 30 00 00 00 00 r:sysfs_t:s0.... backtrace: [<ffffffff814cb1d0>] kmemleak_alloc+0x73/0x98 [<ffffffff811270ab>] __kmalloc+0x100/0x12c [<ffffffff8120775a>] context_struct_to_string+0x106/0x210 [<ffffffff81207cc1>] security_sid_to_context_core+0x10b/0x129 [<ffffffff812090ef>] security_sid_to_context+0x10/0x12 [<ffffffff811fb0da>] selinux_inode_getsecurity+0x7d/0xa8 [<ffffffff811fb127>] selinux_inode_getsecctx+0x22/0x2e [<ffffffff811f4d62>] security_inode_getsecctx+0x16/0x18 [<ffffffff81191dad>] sysfs_setxattr+0x96/0x117 [<ffffffff811542f0>] __vfs_setxattr_noperm+0x73/0xd9 [<ffffffff811543d9>] vfs_setxattr+0x83/0xa1 [<ffffffff811544c6>] setxattr+0xcf/0x101 [<ffffffff81154745>] sys_lsetxattr+0x6a/0x8f [<ffffffff814efda9>] system_call_fastpath+0x16/0x1b [<ffffffffffffffff>] 0xffffffffffffffff unreferenced object 0xffff88024163c5a0 (size 96): comm "systemd", pid 1, jiffies 4294683888 (age 94.553s) hex dump (first 32 bytes): 00 00 00 00 ed 41 00 00 00 00 00 00 00 00 00 00 .....A.......... 00 00 00 00 00 00 00 00 0c 64 42 4f 00 00 00 00 .........dBO.... backtrace: [<ffffffff814cb1d0>] kmemleak_alloc+0x73/0x98 [<ffffffff81127402>] kmem_cache_alloc_trace+0xc4/0xee [<ffffffff81191cbe>] sysfs_init_inode_attrs+0x2a/0x83 [<ffffffff81191dd6>] sysfs_setxattr+0xbf/0x117 [<ffffffff811542f0>] __vfs_setxattr_noperm+0x73/0xd9 [<ffffffff811543d9>] vfs_setxattr+0x83/0xa1 [<ffffffff811544c6>] setxattr+0xcf/0x101 [<ffffffff81154745>] sys_lsetxattr+0x6a/0x8f [<ffffffff814efda9>] system_call_fastpath+0x16/0x1b [<ffffffffffffffff>] 0xffffffffffffffff ` Signed-off-by:

commit da3e6ec2 upstream. In commit c6dc001f "staging: r8712u: Merging Realtek's latest (v2.6.6). Various fixes", the returned qual.qual member of the iw_statistics struct was changed. For strong signals, this change made no difference; however for medium and weak signals it results in a low signal that shows considerable fluctuation, When using wicd for a medium-strength AP, the value reported in the status line is reduced from 100% to 60% by this bug.

commit 9f4bc8cf upstream. In commit a5ee6529 "staging: r8712u: Interface-state not fully tracked", the private boolean "bup" was set false when the interface was brought down, as that seemed appropriate. This change has not caused any problems when using NetworkManager or manual control of the device; however, when wicd control is used, there is a locking problem in wpa_supplicant, as shown in https://bugzilla.kernel.org/show_bug.cgi?id=42818. This fix reverts the only code change in commit a5ee6529. My analysis is that "bup" is badly named. In its present form, it seems to indicate the up/down state of the device, but its usage is more consistent with an initialized/uninitialized state. That problem will be addressed in a later patch. Note: Commit 8c213fa, which introdued asynchronous firmware loading for this driver, exposed this bug to a greater extent. That bug is addressed in the next patch in this series. This bug is also responsible for the bug in https://bugzilla.kernel.org/show_bug.cgi?id=42815. and this bug is also part of the problems discussed at https://bugs.archlinux.org/task/27996#comment89950.

commit 07386343 upstream. When this driver was upgraded to the vendor 20100831 version in commit 93c55dda et al,, one listhead initialization was missed. This broke complete operation of the driver whenever AP mode was enabled. This fixes https://bugs.archlinux.org/task/27996. The configuration parameter R8712_AP is misleading as the driver cannot function as an AP without a heavily hacked version of hostapd. Thus, it makes sense to remove the parameter; however the code and data configured for the option is left in. Signed-off-by:

This was not noticed because the two consecutive bracketless if statements made it syntactically correct. Signed-off-by:

commit 210787e8 upstream. On il3945_down procedure we free tx queue data and nullify il->txq pointer. After that we drop mutex and then cancel delayed works. There is possibility, that after drooping mutex and before the cancel, some delayed work will start and crash while trying to send commands to the device. For example, here is reported crash in il3945_bg_reg_txpower_periodic(): https://bugzilla.kernel.org/show_bug.cgi?id=42766#c10 Patch fix problem by adding il->txq check on works that send commands, hence utilize tx queue.
