BIOS/ACPI on devices with WMI interface version 0 does not clear buffer before filling it. So next time when BIOS/ACPI send WMI event which is smaller as previous then it contains garbage in buffer from previous event. BIOS/ACPI on devices with WMI interface version 1 clears buffer and sometimes send more events in buffer at one call. Since commit 83fc44c3 ("dell-wmi: Update code for processing WMI events") dell-wmi process all events in buffer (and not just first). To prevent reading garbage from the buffer we process only the first event on devices with WMI interface version 0.

For these models, when the airplane mode hotkey (Fn+F2) is pressed, a query 0x0B is started in the Embedded Controller, and all this query does is a notify ASHS with the value 0x88 (for acpi_osi >= "Windows 2012"): Scope (_SB.PCI0.SBRG.EC0) { (...)

This fixes CVE-2016-0728. If a thread is asked to join as a session keyring the keyring that's already set as its session, we leak a keyring reference. This can be tested with the following program: #include <stddef.h> #include <stdio.h> #include <sys/types.h> #include <keyutils.h> int main(int argc, const char *argv[]) { int i = 0; key_serial_t serial; serial = keyctl(KEYCTL_JOIN_SESSION_KEYRING, "leaked-keyring"); if (serial < 0) { perror("keyctl"); return -1; } if (keyctl(KEYCTL_SETPERM, serial, KEY_POS_ALL | KEY_USR_ALL) < 0) { perror("keyctl"); return -1; } for (i = 0; i < 100; i++) { serial = keyctl(KEYCTL_JOIN_SESSION_KEYRING, "leaked-keyring"); if (serial < 0) { perror("keyctl"); return -1; } } return 0; } If, after the program has run, there something like the following line in /proc/keys: 3f3d898f I--Q--- 100 perm 3f3f0000 0 0 keyring leaked-keyring: empty with a usage count of 100 * the number of times the program has been run, then the kernel is malfunctioning.

Certain Toshiba models with the second generation keyboard backlight (type 2) do not generate the keyboard backlight changed event (0x92), and thus, the sysfs entries are never being updated. This patch adds a workquee and a global boolean variable to address the issue. For those models that do generate the event, the sysfs entries are being updated via the *notify function and the boolean is set to true to avoid a second call to update the entries. For those models that do not generate the event, the workquee is used to update the sysfs entries and also to emulate the event via netlink, to make userspace aware of such change.
