* fix a hang which can occur during shutdown migration * do not allow nodes to join during recovery * when restarting lock mastery, do not ignore nodes which come up * more than one node could become recovery master, fix this * sleep to allow some time for heartbeat state to catch up to network * extra debug info for bad recovery state problems * make DLM_RECO_NODE_DATA_DONE a valid state for non-master recovery nodes * prune all locks from dead nodes on $RECOVERY lock resources * do NOT automatically add new nodes to mle nodemaps until they have properly joined the domain * make sure dlm_pick_recovery_master only exits when all nodes have synced * properly handle dlmunlock errors in dlm_pick_recovery_master * do not propagate network errors in dlm_send_begin_reco_message * dead nodes were not being put in the recovery map sometimes, fix this * dlmunlock was failing to clear the unlock actions on DLM_DENIED Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> Signed-off-by: Mark Fasheh <mark.fasheh@oracle.com>

2006-02-03[PATCH] RocketPoint 1520 [hpt366] fails clock stabilizationLoren M. Lang
I just purchased a HighPoint Rocket 1520 SATA controller. There seems to be no libata driver (yet), but there is an ide driver, hpt366. When the driver gets loaded, it causes a kernel NULL pointer dereference in pci_bus_clock_list. It seems to be because the driver is waiting for clock stabilization in init_hpt37x() which never comes. The driver just continues on with the pci drvdata set to NULL, instead of a valid clock entry. The following patch prevents the NULL dereference from happening, but instead exit with an error.

2006-02-03[PATCH] stop CompactFlash devices being marked as removableRichard Purdie
This patch stops CompactFlash devices being marked as removable. They are not removable (as defined by Linux) as the media and device are inseparable. When a card is removed, the whole device is removed from the system and never sits in a media-less state. This stops some nasty udev device creation/destruction loops. Further, once this change is made, there is no need for ide to can be removed from ide_drive_t.

2006-02-03[PATCH] IPMI: fix issues reported by Coverity in ipmi_msghandler.cJayachandran C
While looking to the report by Coverity in ipmi, I came across the following issue: The IPMI message handler relies on two defines which are the same -one in include/linux/ipmi.h #define IPMI_NUM_CHANNELS 0x10 and one in drivers/char/ipmi/ipmi_msghandler. #define IPMI_MAX_CHANNELS 16 These are used interchangeably in ipmi_msghandler.c, but since the array addr->channels[] is of size IPMI_MAX_CHANNELS, I have made a patch that uses IPMI_MAX_CHANNELS for all the checks for the array index.

2006-02-03[PATCH] new tty buffering locking fixPaul Fulghum
Change locking in the new tty buffering facility from using tty->read_lock, which is currently ignored by drivers and thus ineffective. New locking uses a new tty buffering specific lock enforced centrally in the tty buffering code. Two drivers (esp and cyclades) are updated to use the tty buffering functions instead of accessing tty buffering internals directly. This is required for the new locking to work.

2006-02-03[PATCH] Export cpu topology in sysfsZhang, Yanmin
The patch implements cpu topology exportation by sysfs. Items (attributes) are similar to /proc/cpuinfo. 1) /sys/devices/system/cpu/cpuX/topology/physical_package_id: represent the physical package id of cpu X; 2) /sys/devices/system/cpu/cpuX/topology/core_id: represent the cpu core id to cpu X; 3) /sys/devices/system/cpu/cpuX/topology/thread_siblings: represent the thread siblings to cpu X in the same core; 4) /sys/devices/system/cpu/cpuX/topology/core_siblings: represent the thread siblings to cpu X in the same physical package; To implement it in an architecture-neutral way, a new source file, driver/base/topology.c, is to export the 5 attributes. If one architecture wants to support this feature, it just needs to implement 4 defines, typically in file include/asm-XXX/topology.h. The 4 defines are: #define topology_physical_package_id(cpu) #define topology_core_id(cpu) #define topology_thread_siblings(cpu) #define topology_core_siblings(cpu) The type of **_id is int. The type of siblings is cpumask_t. To be consistent on all architectures, the 4 attributes should have deafult values if their values are unavailable. Below is the rule. 1) physical_package_id: If cpu has no physical package id, -1 is the default value. 2) core_id: If cpu doesn't support multi-core, its core id is 0. 3) thread_siblings: Just include itself, if the cpu doesn't support HT/multi-thread. 4) core_siblings: Just include itself, if the cpu doesn't support multi-core and HT/Multi-thread. So be careful when declaring the 4 defines in include/asm-XXX/topology.h. If an attribute isn't defined on an architecture, it won't be exported. Thank Nathan, Greg, Andi, Paul and Venki.

There is code in setfl() which attempts to preserve the O_APPEND flag on IS_APPEND files... however IS_APPEND files could also be opened O_RDONLY and in that case setfl() should not require O_APPEND... coreutils 5.93 tail -f attempts to set O_NONBLOCK even on regular files... unfortunately if you try this on an append-only log file the result is this: fcntl64(3, F_GETFL) = 0x8000 (flags O_RDONLY|O_LARGEFILE) fcntl64(3, F_SETFL, O_RDONLY|O_NONBLOCK|O_LARGEFILE) = -1 EPERM (Operation not permitted) I offer up the patch below as one way of fixing the problem... i've tested it fixes the problem with tail -f but haven't really tested beyond that.

2006-02-03[PATCH] fix O_DIRECT read of last block in a sparse fileJeff Moyer
Currently, if you open a file O_DIRECT, truncate it to a size that is not a multiple of the disk block size, and then try to read the last block in the file, the read will return 0. The problem is in do_direct_IO, here: /* Handle holes */ if (!buffer_mapped(map_bh)) { char *kaddr; ... if (dio->block_in_file >= i_size_read(dio->inode)>>blkbits) { /* We hit eof */ page_cache_release(page); goto out; } We shift off any remaining bytes in the final block of the I/O, resulting in a 0-sized read. I've attached a patch that fixes this. I'm not happy about how ugly the math is getting, so suggestions are more than welcome. I've tested this with a simple program that performs the steps outlined for reproducing the problem above. Without the patch, we get a 0-sized result from read. With the patch, we get the correct return value from the short read.
