This fixes an issue triggered by running concurrent syncs. One of the syncs would go through while the other would just hang indefinitely. In any case, we never actually want to wake a single waiter, so the *_all functions should be used. Signed-off-by:

We need to set the d_release dop for snapdir and snapped dentries so that the ceph_dentry_info struct gets released. We also use the dcache to cache readdir results when possible, which only works if we know when dentries are dropped from the cache. Since we don't use the dcache for readdir in the hidden snapdir, avoid that case in ceph_dentry_release. Signed-off-by:

Fix the security problem in the CIFS filesystem DNS lookup code in which a malicious redirect could be installed by a random user by simply adding a result record into one of their keyrings with add_key() and then invoking a CIFS CFS lookup [CVE-2010-2524]. This is done by creating an internal keyring specifically for the caching of DNS lookups. To enforce the use of this keyring, the module init routine creates a set of override credentials with the keyring installed as the thread keyring and instructs request_key() to only install lookup result keys in that keyring. The override is then applied around the call to request_key(). This has some additional benefits when a kernel service uses this module to request a key: (1) The result keys are owned by root, not the user that caused the lookup. (2) The result keys don't pop up in the user's keyrings. (3) The result keys don't come out of the quota of the user that caused the lookup. The keyring can be viewed as root by doing cat /proc/keys: 2a0ca6c3 I----- 1 perm 1f030000 0 0 keyring .dns_resolver: 1/4 It can then be listed with 'keyctl list' by root. # keyctl list 0x2a0ca6c3 1 key in keyring: 726766307: --alswrv 0 0 dns_resolver: foo.bar.com Signed-off-by:

In the CONFIG_AUDITSYSCALL fast-path for x86 64-bit system calls, we can pass a bad return value and/or error indication for the system call to audit_syscall_exit(). This happens when TIF_NEED_RESCHED was set as the system call returned, so we went out to schedule() and came back to the exit-audit fast-path. The fix is to reload the user return value register from the pt_regs before using it for audit_syscall_exit(). Both the 32-bit kernel's fast path and the 64-bit kernel's 32-bit system call fast paths work slightly differently, so that they always leave the fast path entirely to reschedule and don't return there, so they don't have the analogous bugs.

In the process of merging kdb to the mainline, the kdb lsmod command stopped printing the base load address of kernel modules.

The gdbserial protocol handler should return an empty packet instead of an error string when ever it responds to a command it does not implement. The problem cases come from a debugger client sending qTBuffer, qTStatus, qSearch, qSupported. The incorrect response from the gdbstub leads the debugger clients to not function correctly. Recent versions of gdb will not detach correctly as a result of this behavior. Signed-off-by:

The Nokia RX51 board code (arch/arm/mach-omap2/board-rx51-peripherals.c) defines a key map for the matrix keypad keyboard. The hardware seems to use all of the 8 rows and 8 columns of the keypad, although not all possible locations are used. The TWL4030 supports keypads with at most 8 rows and 8 columns. Most keys are defined with a row and column number between 0 and 7, except KEY(0xff, 2, KEY_F9), KEY(0xff, 4, KEY_F10), KEY(0xff, 5, KEY_F11), which represent keycodes that should be emitted when entire row is connected to the ground. since the driver handles this case as if we had an extra column in the key matrix. Unfortunately we do not allocate enough space and end up owerwriting some random memory. Reported-and-tested-by:

The kernel's math-emu code contains a macro _FP_FROM_INT() which is used to convert an integer to a raw normalized floating-point value. It does this basically in three steps: 1. Compute the exponent from the number of leading zero bits. 2. Downshift large fractions to put the MSB in the right position for normalized fractions. 3. Upshift small fractions to put the MSB in the right position. There is an boundary error in step 2, causing a fraction with its MSB exactly one bit above the normalized MSB position to not be downshifted. This results in a non-normalized raw float, which when packed becomes a massively inaccurate representation for that input. The impact of this depends on a number of arch-specific factors, but it is known to have broken emulation of FXTOD instructions on UltraSPARC III, which was originally reported as GCC bug 44631 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44631>.
