"mm: add a field to store names for private anonymous memory" (AOSP commit ee8c5f78f09a) uses a depreciated call to get_user_pages which generates the following compile warning: fs/proc/task_mmu.c: In function 'seq_print_vma_name': fs/proc/task_mmu.c:154:3: warning: 'get_user_pages8' is deprecated (declared at include/linux/mm.h:1295) [-Wdeprecated-declarations] pages_pinned = get_user_pages(current, mm, page_start_vaddr, ^ include/linux/mm.h explains get_user_pages function call using struct task_struct *tsk and struct mm_struct *mm (not using current task and current->mm) should now be: get_user_pages_remote Signed-off-by: Michael Scott <michael.scott@linaro.org> Signed-off-by: Amit Pundir <amit.pundir@linaro.org>
2016-06-07ANDROID: usb: gadget: fix MTP OS desc supportAmit Pundir
Upstream commit 1ae1602de028 "configfs: switch ->default groups to a linked list" replaced the current config groups with a linked list. Hence we no longer need to kfree the groups. Also the initialization for default_groups now happens in the function config_group_init() which is called by config_group_init_type_name(). If we call usb_os_desc_prepare_interf_dir() prior to this initialization the kernel crashes when we create MTP function i.e when it reaches configfs_add_default_group(&d->group, os_desc_group) which is accessing uninitialized data. Fix this crash by moving usb_os_desc_prepare_interf_dir() to after the call to config_group_init_type_name().

When kernel.perf_event_open is set to 3 (or greater), disallow all access to performance events by users without CAP_SYS_ADMIN. Add a Kconfig symbol CONFIG_SECURITY_PERF_EVENTS_RESTRICT that makes this value the default. This is based on a similar feature in grsecurity (CONFIG_GRKERNSEC_PERF_HARDEN). This version doesn't include making the variable read-only. It also allows enabling further restriction at run-time regardless of whether the default is changed. https://lkml.org/lkml/2016/1/11/587 Signed-off-by: Ben Hutchings <ben@decadent.org.uk> Bug: 29054680 Change-Id: Iff5bff4fc1042e85866df9faa01bce8d04335ab8

2016-06-07xt_qtaguid: Fix panic caused by processing non-full socket.John Stultz
In an issue very similar to 4e461c777e3 (xt_qtaguid: Fix panic caused by synack processing), we were seeing panics on occasion in testing. In this case, it was the same issue, but caused by a different call path, as the sk being returned from qtaguid_find_sk() was not a full socket. Resulting in the sk->sk_socket deref to fail. This patch adds an extra check to ensure the sk being retuned is a full socket, and if not it returns NULL.

2016-06-07UPSTREAM: procfs: fixes pthread cross-thread naming if !PR_DUMPABLEJanis Danisevskis
The PR_DUMPABLE flag causes the pid related paths of the proc file system to be owned by ROOT. The implementation of pthread_set/getname_np however needs access to /proc/<pid>/task/<tid>/comm. If PR_DUMPABLE is false this implementation is locked out. This patch installs a special permission function for the file "comm" that grants read and write access to all threads of the same group regardless of the ownership of the inode. For all other threads the function falls back to the generic inode permission check. Signed-off-by: Janis Danisevskis <jdanis@google.com>
2016-06-07FROMLIST: wlcore: Disable filtering in AP roleJimmy Perchet
When you configure (set it up) a STA interface, the driver install a multicast filter. This is normal behavior, when one application subscribe to multicast address the filter is updated. When Access Point interface is configured, there is no filter installation and the "filter update" path is disabled in the driver. The problem happens when you switch an interface from STA type to AP type. The filter is installed but there are no means to update it.

2016-06-07xt_qtaguid: Fix panic caused by synack processingJohn Stultz
In upstream commit ca6fb06518836ef9b65dc0aac02ff97704d52a05 (tcp: attach SYNACK messages to request sockets instead of listener) http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ca6fb0651883 The building of synack messages was changed, which made it so the skb->sk points to a casted request_sock. This is problematic, as there is no sk_socket in a request_sock. So when the qtaguid_mt function tries to access the sk->sk_socket, it accesses uninitialized memory. After looking at how other netfilter implementations handle this, I realized there was a skb_to_full_sk() helper added, which the xt_qtaguid code isn't yet using. This patch adds its use, and resovles panics seen when accessing uninitialzed memory when processing synack packets.

Attempts to build sdcardfs as module fail with fs/sdcardfs/lookup.c: In function '__sdcardfs_lookup': fs/sdcardfs/lookup.c:243:5: error: 'LOOKUP_CASE_INSENSITIVE' undeclared This occurs because the define is enclosed with #ifdef CONFIG_SDCARD_FS_CI_SEARCH.

Alternatives would be to use #if IS_ENABLED(CONFIG_SDCARD_FS_CI_SEARCH), or to declare SDCARD_FS_CI_SEARCH as bool, but that does not work because the define is used unconditionally in the source. Note that LOOKUP_CASE_INSENSITIVE is only set but not evaluated in the current source code, so setting the flag has no real effect.

2016-06-07vfs: add d_canonical_path for stacked filesystem supportDaniel Rosenberg
Inotify does not currently know when a filesystem is acting as a wrapper around another fs. This means that inotify watchers will miss any modifications to the base file, as well as any made in a separate stacked fs that points to the same file. d_canonical_path solves this problem by allowing the fs to map a dentry to a path in the lower fs. Inotify can use it to find the appropriate place to watch to be informed of all changes to a file.

When userspace unbinds gadget functions through configfs, the .free_func() callback is always invoked. (in config_usb_cfg_unlink()) Implement it as a no-op to avoid the following crash: [ 68.125679] configfs-gadget gadget: unbind function 'accessory'/ffffffc0720bf000 [ 68.133202] configfs-gadget gadget: unbind function 'audio_source'/ffffffc0012ca3c0 [ 68.142668] tegra-xudc 700d0000.usb-device: ep 0 disabled [ 68.148186] Bad mode in Synchronous Abort handler detected, code 0x86000006 [ 68.155144] CPU: 2 PID: 1 Comm: init Tainted: G U W 3.18.0-09419-g87296c3-dirty #561 [ 68.163743] Hardware name: Google Tegra210 Smaug Rev 1,3+ (DT) [ 68.169566] task: ffffffc0bc8d0000 ti: ffffffc0bc8bc000 task.ti: ffffffc0bc8bc000 [ 68.177039] PC is at 0x0 [ 68.179577] LR is at usb_put_function+0x14/0x1c ....

2016-06-07CHROMIUM: usb: gadget: f_mtp: fix usb_ss_ep_comp_descriptorMark Kuo
wBytesPerInterval in SuperSpeed Endpoint Companion Descriptor needs to be set large enough to reserve enough bus time for associated periodic endpoint. Originally, wBytesPerInterval for mtp's interrupt IN endpoint is set to 2 and its single interrupt transfer will be split into many 2 bytes interrupt transfers. So, we change wBytesPerInterval to INTR_BUFFER_SIZE to ensure interrupt transfer will not be split.

When using platform-data (not DT), we get an OOPS, because drvdata is only initialized after we try to use it. This addresses my comments made on the upstream submission here: https://patchwork.kernel.org/patch/7980651/ Fixes boot on Chrome OS systems, including the Pixel 2.

2016-06-07ANDROID: dm-crypt: run in a WQ_HIGHPRI workqueueTim Murray
(cherry pick from commit ad3ac5180979e5dd1f84e4a807f76fb9fb19f814) Running dm-crypt in a standard workqueue results in IO competing for CPU time with standard user apps, which can lead to pipeline bubbles and seriously degraded performance. Move to a WQ_HIGHPRI workqueue to protect against that. Signed-off-by: Tim Murray <timmurray@google.com> Bug: 25392275 Change-Id: I2828587c754a7c2cafdd78b3323b9896cb8cd4e7
