Add a check to the PM-Timer initialization code. It validates the PM-Timer rate against PIT channel 2 and rejects the PM-Timer if its rate is not withing 5% of the expected number. Rationale: The PMTMR timers of certain (older) mainboards are running at invalid rates, often much faster than the rate expected by the PM-Timer code. This causes the system clock to run much too fast. See also http://bugme.osdl.org/show_bug.cgi?id=2375 Possible workarounds are disabling the PM-Timer in the kernel config or disabling the PM-Timer at boot time through the "clock=tsc" parameter. However, we believe it is more user friendly to automatically validate the PM-Timer rate at boot time before using it as the system time source. Tested by me (with broken timer) and John Stultz (with good timer) and believed to be ok. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

The old 1542 scsi driver is both ISA and MCA. The MCA portions are disabled when !CONFIG_MCA through the typical wrapper scheme (a la pci.h and !CONFIG_PCI). However... the driver unconditionally includes linux/mca.h which in turn unconditionally includes asm/mca.h. This breaks drivers on platforms with ISA but not MCA, like alpha.

The patch below gets rid of io_apic_sync(). io_apic_sync() was introduced in 2.1.104 and it was originally done for masking and unmasking as well. Later the unmasking use got removed but the masking use lingered around. I dont think it was ever justified to do it and clearly since the lack of io_apic_sync() didnt break some of the other writes we do to the IO-APIC registers, it must be unnecessary in the masking case too.

the patch below gets rid of APIC_LOCKUP_DEBUG. It has been in the kernel for more than 3 years and the message was only reported once during that period of time - and even in that case it was a side-effect of a really bad crash. The lockup workaround works, the debugging code can be moved out.

This cleans up io_apic.c a bit -- I do not really like 4 copies of same code. Ingo said: yeah, agreed - i checked & test it, it's ok. I made a small modification (see the patch below) to uninline the __modify_IO_APIC_irq() function - shaving 0.5K off the kernel's size.

do_generic_mapping_read() { isize1 = i_size_read(); ... readpage copy_to_user up to isize1; } readpage() { isize2 = i_size_read(); ... read blocks ... zero-fill all blocks past isize2 } If a second thread runs truncate and shrinks i_size, so isize1 and isize2 are different, the read can return up to a page of zero-fill that shouldn't really exist. The trick is to read isize1 after doing the readpage. I realised this is the right way to do it without having to change the readpage API.

Andrea Arcangeli <andrea@suse.de> points out that invalidate_inode_pages2() is supposed to mark mapped-into-pagetable pages as not uptodate so that next time someone faults the page in we will go get a new version from backing store. The callers are the direct-io code and the NFS "something changed on the server" code. In both these cases we do need to go and re-read the page.

Various small tweaks. Compiled and booted. 1. add IORESOURCE_BUSY | IORESOURCE_MEM also for the kernel code and data resources. I don't believe this actually matters one bit, but they're hooked into a BUSY/MEM parent ("System RAM") and marking them busy seems to make sense. 2. delete the .start = 1M default for the kernel code resource. This isn't actually a change; it's set to virt_to_phys(_text) in setup_arch() overriding any default anyways. 3. s/vram_resource/video_ram_resource/. Lines up much nicer with video_rom_resource... 4. s/checksum/romchecksum/. setup.c is a fairly large file, and "checksum" pollutes the namespace.

Here is a reworked version of my patch to ext3 to retry certain filesystem operations after an ENOSPC error. The ext3_should_retry_alloc() function will not wait on the currently running transaction if there is a currently active handle; hence this should avoid deadlocks in the Lustre use case. The patch is versus BK-recent. I've also included a simple, reliable test case which demonstrates the problem this patch is intended to fix. (Note that BK-recent is not sufficient to address this test case, and waiting on the commiting transaction in ext3_new_block is also not sufficient. Been there, tried that, didn't work. We need to do the full-bore retry from the top level. The ext3_should_retry_alloc() will only wait on the committing transaction if there is an active handle; hence Lustre will probably also need to use ext3_should_retry_alloc() if it wants to reliably avoid this particular problem.) #!/bin/sh # # TEST_DIR=/tmp IMAGE=$TEST_DIR/retry.img MNTPT=$TEST_DIR/retry.mnt TEST_SRC=/usr/projects/e2fsprogs/e2fsprogs/build MKE2FS_OPTS="" IMAGE_SIZE=8192 umount $MNTPT dd if=/dev/zero of=$IMAGE bs=4k count=$IMAGE_SIZE mke2fs -j -F $MKE2FS_OPTS $IMAGE function test_log () { echo $* logger -p local4.notice $* } mkdir -p $MNTPT mount -o loop -t ext3 $IMAGE $MNTPT test_log Retry test: BEGIN for i in `seq 1 3` do test_log "Retry test: Loop $i" echo 2 > /proc/sys/fs/jbd-debug while ! mkdir -p $MNTPT/foo/bar do test_log "Retry test: mkdir failed" sleep 1 done echo 0 > /proc/sys/fs/jbd-debug cp -r $TEST_SRC $MNTPT/foo/bar 2> /dev/null rm -rf $MNTPT/* done umount $MNTPT test_log "Retry test: END" akpm@osdl.org Rework the code to make it a formal JBD API entry point.

std_resources.{c,h} was only split off due to pc9800 wanting to override it. With it gone, it might as well be merged back in. Doesn't change any code. It was compiled and booted. This time this also actually doesn't break compilation of any of the subarches. That's to say, any further. I guess it might have been my .config (my regular PC config, with just the subarch switched through menuconfig) or O=, but only ELAN actually compiled. Voyager and VISWS bombed out at the final link and NUMAQ much sooner (with "physnode_map undeclared" during compilation of numaq.c).

The following patches introduce per user rlimits for both queued signals and POSIX message queues. The changes touch all the arches resource.h files as well as init_task.c to get the rlimit defaults setup. Both require caching the user_struct to avoid problems with setuid(). The signal changes makes some small changes to send_signal() to pass along the task being signalled to get proper accounting for signals initiated in interrupt. Thanks to Marcelo for getting this one going. This patch: Add an rlimit entry to control the maximum number of pending signals a user may have. This is essentially just the resource.h changes.

There were definately some problems in there. I've made some changes and tested with a lot of bounds. I don't have a machine with enough memory to fill it up (it would take ~16GB on a 64-bit machine), but I use the "above" code to simulate a lot of situations. The problems were: * IDR_FULL was not the right value * idr_get_new_above() was not defined in the headers or documented. * idr_alloc() bug-ed if there was a race and not enough memory was allocated. It should have returned NULL. * id will overflow when you go past the end. * There was a "(id >= (1 << (layers*IDR_BITS)))" comparison, but at the top layer it would overflow the id and be zero. * The allocation should return ENOSPC for an "above" value with nothing above it, but it returned EAGAIN. I have not tested on 64-bits (as I don't have a 64-bit machine). I've included the files, a diff from the previous version, and my test programs. For the test programs, idr_test <size> will just attempt to allocate <size> elements, check them, free them, and check them again. idr_test2 <size> <incr> will allocate <size> element with <incr> between them. idr_test3 just tests some bounds and tries all values with just a few in the idr.

idr_get_new() currently returns an incrementing counter in the top 8 bits of the counter. Which means that most users have to mask it off again, and we only have a 24-bit range. So remove that counter. Also: - Remove the BITS_PER_INT define due to namespace collision risk. - Make MAX_ID_SHIFT 31, so counters have a 0 to 2G-1 range. - Why is MAX_ID_SHIFT using sizeof(int) and not sizeof(long)? If it's for consistency across 32- and 64-bit machines, why not just make it "31"? - Does this still hold true with the counter removed? /* We can only use half the bits in the top level because there are only four possible bits in the top level (5 bits * 4 levels = 25 bits, but you only use 24 bits in the id). */ If not, what needs to change?

* On a 32-bit architecture, the idr code will cease to work if you add more than 2^20 entries. You will not be able to find many of the entries. The problem is that the IDR code uses 5-bit chunks of the number and the lower portion used by IDR is 24 bits, so you have one bit that leaks over into the comparisons that should not be there. The solution is to mask off that bit before doing IDR processing. This actually causes the POSIX timer code to crash if you create that many timers. I have included an idr_test.tar.gz file that demonstrates this with and without the fix, in case you need more evidence :). * When the IDR fills up, it returns -1. However, there was no way to check for this condition. This patch adds the ability to check for the idr being full and fixes all the users. It also fixes a problem in fs/super.c where the idr code wasn't checking for -1. * There was a race condition creating POSIX timers. The timer was added to a task struct for another process then the data for the timer was filled out. The other task could use/destroy time timer as soon as it is in the task's queue and the lock is released. This moves settup up the timer data to before the timer is enqueued or (for some data) into the lock. * Change things so that the caller doesn't need to run idr_full() to find out the reason for an idr_get_new() failure. Just return -ENOSPC if the tree was full, or -EAGAIN if the caller needs to re-run idr_pre_get() and try again.

reiserfsck --rebuild-tree expects the only key with a packing locality of 1 to be for the root directory (key [1 2]).

From: <mason@suse.com> From: <jeffm@suse.com> The current reiserfs allocator pretty much allocates things sequentially from the start of the disk, it works very nicely for desktop loads but once you've got more then one proc doing io data files can fragment badly. One obvious solution is something like ext2's bitmap groups, which puts file data into different areas of the disk based on which subdirectory they are in. The problem with bitmap groups is that if you've got a group of subdirectories their contents will be spread out all over the disk, leading to lots of seeks during a sequential read. This allocator patch uses the packing locality to determine which bitmap group to allocate from, but when you create a file it looks in the bitmaps to see how 'full' that packing locality already is. If it hasn't been heavily used yet, the packing locality is inherited from the parent directory putting files in new subdirs close to the parent subdir, otherwise it is the inode number of the parent directory putting new files far away from the parent subdir. The end result is fewer bitmap groups for the same working set. For example, one test data set created by 20 procs running in parallel has 6822 subdirs. And with vanilla reiserfs that would mean 6822 packing localities. This patch turns that into 26 packing localities. This makes sequential reads of big directory trees more efficient, but it also makes the btree more efficient in general. Things end up sorted better because groups of subdirs end up with similar keys in the btree, instead of being spread out all over. The bitmap grouping code tries to use the start of each bitmap group for metadata, and offsets the data slightly. The data and metadata are still close together, but not completely intermixed like they are in the default allocator. The end result is that leaf nodes tend to be close to each other, making metadata readahead more effective. The old block allocator had the ability to enforce a minimum allocation size, but did not use it. It now tries to do a pass looking for larger allocation chunks before falling back to the old behaviour of taking any blocks it can find. The patch changes the defaults to: mount -o alloc=skip_busy:dirid_groups:packing_groups You can get back the old behaviour with mount -o alloc=skip_busy mount -o alloc=dirid_groups will turn on the bitmap groups mount -o alloc=packing_groups turns on the packing locality reduction code mount -o alloc=skip_busy:dirid_groups turns on both dirid_groups and skip_busy Finally the patch adds a mount -o alloc=oid_groups, which puts files into bitmap groups based on a hash of their objectid. This would be used for databases or other situations where you have a limited number of very large files. This command will tell you how many packing localities are actually in use: debugreiserfs -d /dev/xxx | grep '^|.*SD' | sed 's/^.....//' | awk '{print $1}' | sort -u | wc -l Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

This patch allows for misc binaries to run with credentials and security token that are calculated according to the binaries, and not according to the interpreter, which is the legacy behavior of binfmt_misc. The way it is done is by calling prepare_binprm, which is where these attributes are calculated, before switching the 'file' field in the bprm from the binary to the interpreter. This feature should be used with care, since the interpreter will have root permissions when running a setuid binary owned by root. Please note - - Only root can register an interpreter with binfmt_misc. The feature is documented and the administrator is advised to handle it with care - The new feature is enabled only with a special flag in the registration string. When this flag is not specified the current behavior of binfmt_misc is kept - This is the only 'right' way for an interpreter to know the correct AT_SECURE value for the interpreted binary From: Chris Wright <chrisw@osdl.org> This patchset looks OK, except for one problem. It installs the fd (which could've been unreadable) without unsharing the ->files. So someone can use this to read unreadable yet executable files. Here's a patch which fixes that up. I added one bit that's commented out because I'm not positive if a final steal_locks() is needed. I did a fair amount of rearranging to simplify the error conditions relative to the fd_install(), and unshare_files(). From: Chris Wright <chrisw@osdl.org> I found that the intel patchset (and mine as well) leaked i_writecount on the original executed file. In addition, I verified that the steal_locks() bit is indeed needed. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
