linux/audit.h: move ptrace.h include to kernel header

2013-01-11T22:54:56+00:00

While the kernel internals want pt_regs (and so it includes linux/ptrace.h), the user version of audit.h does not need it. So move the include out of the uapi version. This avoids issues where people want the audit defines and userland ptrace api. Including both the kernel ptrace and the userland ptrace headers can easily lead to failure.

audit: create explicit AUDIT_SECCOMP event type

2013-01-11T22:54:55+00:00

The seccomp path was using AUDIT_ANOM_ABEND from when seccomp mode 1 could only kill a process. While we still want to make sure an audit record is forced on a kill, this should use a separate record type since seccomp mode 2 introduces other behaviors. In the case of "handled" behaviors (process wasn't killed), only emit a record if the process is under inspection. This change also fixes userspace examination of seccomp audit events, since it was considered malformed due to missing fields of the AUDIT_ANOM_ABEND event type.

ipc: introduce message queue copy feature

2013-01-05T00:11:45+00:00

This patch is required for checkpoint/restore in userspace. c/r requires some way to get all pending IPC messages without deleting them from the queue (checkpoint can fail and in this case tasks will be resumed, so queue have to be valid). To achive this, new operation flag MSG_COPY for sys_msgrcv() system call was introduced. If this flag was specified, then mtype is interpreted as number of the message to copy. If MSG_COPY is set, then kernel will allocate dummy message with passed size, and then use new copy_msg() helper function to copy desired message (instead of unlinking it from the queue). Notes: 1) Return -ENOSYS if MSG_COPY is specified, but CONFIG_CHECKPOINT_RESTORE is not set. Signed-off-by: Stanislav Kinsbursky Cc: Serge Hallyn Cc: "Eric W.

PCI: Add PCIe Link Capability link speed and width names

2012-12-26T17:39:23+00:00

Add standard #defines for the Supported Link Speeds field in the PCIe Link Capabilities register. Note that prior to PCIe spec r3.0, these encodings were defined: 0001b 2.5GT/s Link speed supported 0010b 5.0GT/s and 2.5GT/s Link speed supported Starting with spec r3.0, these encodings refer to bits 0 and 1 in the Supported Link Speeds Vector in the Link Capabilities 2 register, and bits 0 and 1 there mean 2.5 GT/s and 5.0 GT/s, respectively. Therefore, code that followed r2.0 and interpreted 0x1 as 2.5GT/s and 0x2 as 5.0GT/s will continue to work, and we can identify a device using the new encodings because it will have a non-zero Link Capabilities 2 register.

Highlights: - Add initial f2fs source codes - Fix an endian conversion bug - Fix build failures on random configs - Fix the power-off-recovery routine - Minor cleanup, coding style, and typos patches" From the Kconfig help text: F2FS is based on Log-structured File System (LFS), which supports versatile "flash-friendly" features. The design has been focused on addressing the fundamental issues in LFS, which are snowball effect of wandering tree and high cleaning overhead. Since flash-based storages show different characteristics according to the internal geometry or flash memory management schemes aka FTL, F2FS and tools support various parameters not only for configuring on-disk layout, but also for selecting allocation and cleaning algorithms. and there's an article by Neil Brown about it on lwn.net: http://lwn.net/Articles/518988/ * tag 'for-3.8-merge' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs: (36 commits) f2fs: fix tracking parent inode number f2fs: cleanup the f2fs_bio_alloc routine f2fs: introduce accessor to retrieve number of dentry slots f2fs: remove redundant call to f2fs_put_page in delete entry f2fs: make use of GFP_F2FS_ZERO for setting gfp_mask f2fs: rewrite f2fs_bio_alloc to make it simpler f2fs: fix a typo in f2fs documentation f2fs: remove unused variable f2fs: move error condition for mkdir at proper place f2fs: remove unneeded initialization f2fs: check read only condition before beginning write out f2fs: remove unneeded memset from init_once f2fs: show error in case of invalid mount arguments f2fs: fix the compiler warning for uninitialized use of variable f2fs: resolve build failures f2fs: adjust kernel coding style f2fs: fix endian conversion bugs reported by sparse f2fs: remove unneeded version.h header file from f2fs.h f2fs: update the f2fs document f2fs: update Kconfig and Makefile ...
