* [PATCH] Standardize pxx_page macrosDave McCracken2006-09-262-3/+6
| | | | | | | | | | | | | | | | | | | | | One of the changes necessary for shared page tables is to standardize the pxx_page macros. pte_page and pmd_page have always returned the struct page associated with their entry, while pte_page_kernel and pmd_page_kernel have returned the kernel virtual address. pud_page and pgd_page, on the other hand, return the kernel virtual address. Shared page tables needs pud_page and pgd_page to return the actual page structures. There are very few actual users of these functions, so it is simple to standardize their usage. Since this is basic cleanup, I am submitting these changes as a standalone patch. Per Hugh Dickins' comments about it, I am also changing the pxx_page_kernel macros to pxx_page_vaddr to clarify their meaning.

* [PATCH] remove set_wmb - arch removalSteven Rostedt2006-07-151-1/+0
| | | | | | | | | | | | | | | | set_wmb should not be used in the kernel because it just confuses the code more and has no benefit. Since it is not currently used in the kernel this patch removes it so that new code does not include it. All archs define set_wmb(var, value) to do { var = value; wmb(); } while(0) except ia64 and sparc which use a mb() instead. But this is still moot since it is not used anyway. Hasn't been tested on any archs but x86 and x86_64 (and only compiled tested) Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] Make cpu_relax() imply barrier() on all archesChase Venters2006-07-121-1/+2
| | | | | | | | | | | | | During the recent discussion of taking 'volatile' off of the spinlock, I noticed that while most arches #define cpu_relax() such that it implies barrier(), some arches define cpu_relax() to be empty. This patch changes the definition of cpu_relax() for frv, h8300, m68knommu, sh, sh64, v850 and xtensa from an empty while(0) to the compiler barrier().

* | [AF_UNIX]: Datagram getpeersecCatherine Zhang2006-06-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch implements an API whereby an application can determine the label of its peer's Unix datagram sockets via the auxiliary data mechanism of recvmsg. Patch purpose: This patch enables a security-aware application to retrieve the security context of the peer of a Unix datagram socket. The application can then use this security context to determine the security context for processing on behalf of the peer who sent the packet. Patch design and implementation: The design and implementation is very similar to the UDP case for INET sockets. Basically we build upon the existing Unix domain socket API for retrieving user credentials. Linux offers the API for obtaining user credentials via ancillary messages (i.e., out of band/control messages that are bundled together with a normal message). To retrieve the security context, the application first indicates to the kernel such desire by setting the SO_PASSSEC option via getsockopt. Then the application retrieves the security context using the auxiliary data mechanism. An example server application for Unix datagram socket should look like this: toggle = 1; toggle_len = sizeof(toggle); setsockopt(sockfd, SOL_SOCKET, SO_PASSSEC, &toggle, &toggle_len); recvmsg(sockfd, &msg_hdr, 0); if (msg_hdr.msg_controllen > sizeof(struct cmsghdr)) { cmsg_hdr = CMSG_FIRSTHDR(&msg_hdr); if (cmsg_hdr->cmsg_len <= CMSG_LEN(sizeof(scontext)) && cmsg_hdr->cmsg_level == SOL_SOCKET && cmsg_hdr->cmsg_type == SCM_SECURITY) { memcpy(&scontext, CMSG_DATA(cmsg_hdr), sizeof(scontext)); } } sock_setsockopt is enhanced with a new socket option SOCK_PASSSEC to allow a server socket to receive security context of the peer. Testing: We have tested the patch by setting up Unix datagram client and server applications. We verified that the server can retrieve the security context using the auxiliary data mechanism of recvmsg.

* [PATCH] Configurable NODES_SHIFTYasunori Goto2006-04-111-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current implementations define NODES_SHIFT in include/asm-xxx/numnodes.h for each arch. Its definition is sometimes configurable. Indeed, ia64 defines 5 NODES_SHIFT values in the current git tree. But it looks a bit messy. SGI-SN2(ia64) system requires 1024 nodes, and the number of nodes already has been changeable by config. Suitable node's number may be changed in the future even if it is other architecture. So, I wrote configurable node's number. This patch set defines just default value for each arch which needs multi nodes except ia64. But, it is easy to change to configurable if necessary. On ia64 the number of nodes can be already configured in generic ia64 and SN2 config. But, NODES_SHIFT is defined for DIG64 and HP'S machine too. So, I changed it so that all platforms can be configured via CONFIG_NODES_SHIFT. It would be simpler.

* [PATCH] 2TB files: st_blocks is invalid when calling stat64Takashi Sato2006-03-261-7/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch series fixes the following problems on 32 bits architecture. o stat64 returns the lower 32 bits of blocks, although userland st_blocks has 64 bits, because i_blocks has only 32 bits. The ioctl with FIOQSIZE has the same problem. o As Dave Kleikamp said, making >2TB file on JFS results in writing an invalid block number to disk inode. The cause is the same as above too. o In generic quota code dquot_transfer(), the file usage is calculated from i_blocks via inode_get_bytes(). If the file is over 2TB, the change of usage is less than expected. The cause is the same as above too. o As Trond Myklebust said, statfs64's entries related to blocks are invalid on statfs64 for a network filesystem which has more than 2^32-1 blocks with CONFIG_LBD disabled. [PATCH 3/3] We made patches to fix problems that occur when handling a large filesystem and a large file. It was discussed on the mails titled "stat64 for over 2TB file returned invalid st_blocks".

* [PATCH] POLLRDHUP/EPOLLRDHUP handling for half-closed devices notificationsDavide Libenzi2006-03-251-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the half-closed devices notifiation, by adding a new POLLRDHUP (and its alias EPOLLRDHUP) bit to the existing poll/select sets. Since the existing POLLHUP handling, that does not report correctly half-closed devices, was feared to be changed, this implementation leaves the current POLLHUP reporting unchanged and simply add a new bit that is set in the few places where it makes sense. The same thing was discussed and conceptually agreed quite some time ago: http://lkml.org/lkml/2003/7/12/116 Since this new event bit is added to the existing Linux poll infrastruture, even the existing poll/select system calls will be able to use it. As far as the existing POLLHUP handling, the patch leaves it as is. The pollrdhup-2.6.16.rc5-0.10.diff defines the POLLRDHUP for all the existing archs and sets the bit in the six relevant files. The other attached diff is the simple change required to sys/epoll.h to add the EPOLLRDHUP definition. There is "a stupid program" to test POLLRDHUP delivery here: http://www.xmailserver.org/pollrdhup-test.c It tests poll(2), but since the delivery is same epoll(2) will work equally.

| | | | | | | | | | | | | | | | | | | | | | | | Currently, copy-on-write may change the physical address of a page even if the user requested that the page is pinned in memory (either by mlock or by get_user_pages). This happens if the process forks meanwhile, and the parent writes to that page. As a result, the page is orphaned: in case of get_user_pages, the application will never see any data hardware DMA's into this page after the COW. In case of mlock'd memory, the parent is not getting the realtime/security benefits of mlock. In particular, this affects the Infiniband modules which do DMA from and into user pages all the time. This patch adds madvise options to control whether memory range is inherited across fork. Useful e.g. for when hardware is doing DMA from/into these pages. Could also be useful to an application wanting to speed up its forks by cutting large areas out of consideration. Signed-off-by: Michael S.

This only deals with the core clocks at the moment, though it's trivial for other drivers to define their own clocks as desired.

* [PATCH] sh: I/O routine cleanups and ioremap() overhaulPaul Mundt2006-01-173-201/+244
| | | | | | | | | | | | | | | | | This introduces a few changes in the way that the I/O routines are defined on SH, specifically so that things like the iomap API properly wrap through the machvec for board-specific quirks. In addition to this, the old p3_ioremap() work is converted to a more generic __ioremap() that will map through the PMB if it's available, or fall back on page tables for everything else. An alpha-like IO_CONCAT is also added so we can start to clean up the board-specific io.h mess, which will be handled in board update patches..

* [PATCH] sh: IRQ handler updatesPaul Mundt2006-01-172-65/+427
| | | | | | | | | | | | | | This moves the various IRQ controller drivers into a new subdirectory, and also extends the INTC2 IRQ handler to also deal with SH7760 and SH7780 interrupts, rather than just ST-40. The old CONFIG_SH_GENERIC has also been removed from the IRQ definitions, as new ports are expected to be based off of CONFIG_SH_UNKNOWN. Since there are plenty of incompatible machvecs, CONFIG_SH_GENERIC doesn't make sense anymore.

* [PATCH] sh: DMA updatesPaul Mundt2006-01-175-26/+97
| | | | | | | | | | | | | This extends the current SH DMA API somewhat to support a proper virtual channel abstraction, and also works to represent this through the driver model by giving each DMAC its own platform device. There's also a few other minor changes to support a few new CPU subtypes, and make TEI generation for the SH DMAC configurable.

* [PATCH] atomic_long_t & include/asm-generic/atomic.h V2Christoph Lameter2006-01-061-0/+1
| | | | | | | | | | | | | | | | | | | Several counters already have the need to use 64 atomic variables on 64 bit platforms (see mm_counter_t in sched.h). We have to do ugly ifdefs to fall back to 32 bit atomic on 32 bit platforms. The VM statistics patch that I am working on will also make more extensive use of atomic64. This patch introduces a new type atomic_long_t by providing definitions in asm-generic/atomic.h that works similar to the c "long" type. Its 32 bits on 32 bit platforms and 64 bits on 64 bit platforms. Also cleans up the determination of the mm_counter_t in sched.h.
