2008-02-08splice: missing user pointer access verificationJens Axboe1-0/+8
vmsplice_to_user() must always check the user pointer and length with access_ok() before copying. Likewise, for the slow path of copy_from_user_mmap_sem() we need to check that we may read from the user region.

2008-02-08quota: turn quotas off when remounting read-onlyJan Kara1-0/+1
Turn off quotas before filesystem is remounted read only. Otherwise quota will try to write to read-only filesystem which does no good... We could also just refuse to remount ro when quota is enabled but turning quota off is consistent with what we do on umount.

2008-02-08ext3 can fail badly when device stops accepting BIO_RW_BARRIER requestsNeil Brown1-1/+2
Some devices - notably dm and md - can change their behaviour in response to BIO_RW_BARRIER requests. They might start out accepting such requests but on reconfiguration, they find out that they cannot any more. ext3 (and other filesystems) deal with this by always testing if BIO_RW_BARRIER requests fail with EOPNOTSUPP, and retrying the write requests without the barrier (probably after waiting for any pending writes to complete). However there is a bug in the handling for this for ext3. When ext3 (jbd actually) decides to submit a BIO_RW_BARRIER request, it sets the buffer_ordered flag on the buffer head. If the request completes successfully, the flag STAYS SET. Other code might then write the same buffer_head after the device has been reconfigured to not accept barriers. This write will then fail, but the "other code" is not ready to handle EOPNOTSUPP errors and the error will be treated as fatal. This can be seen without having to reconfigure a device at exactly the wrong time by putting: if (buffer_ordered(bh)) printk("OH DEAR, and ordered buffer\n"); in the while loop in "commit phase 5" of journal_commit_transaction. If it ever prints the "OH DEAR ..." message (as it does sometimes for me), then that request could (in different circumstances) have failed with EOPNOTSUPP, but that isn't tested for. My proposed fix is to clear the buffer_ordered flag after it has been used, as in the following patch.

2008-02-08reduce large do_mount stack usage with noinlinesEric Sandeen1-5/+13
do_mount() uses a whopping 616 bytes of stack on x86_64 in 2.6.24-mm1, largely thanks to gcc inlining the various helper functions. noinlining these can slim it down a lot; on my box this patch gets it down to 168, which is mostly the struct nameidata nd; left on the stack. These functions are called only as do_mount() helpers; none of them should be in any path that would see a performance benefit from inlining...

2008-02-08buffer_head: fix private_list handlingJan Kara1-4/+19
There are two possible races in handling of private_list in buffer cache. 1) When fsync_buffers_list() processes a private_list, it clears b_assoc_mapping and moves buffer to its private list. Now drop_buffers() comes, sees a buffer is on list so it calls __remove_assoc_queue() which complains about b_assoc_mapping being cleared (as it cannot propagate possible IO error). This race has been actually observed in the wild. 2) When fsync_buffers_list() processes a private_list, mark_buffer_dirty_inode() can be called on bh which is already on the private list of fsync_buffers_list(). As buffer is on some list (note that the check is performed without private_lock), it is not readded to the mapping's private_list and after fsync_buffers_list() finishes, we have a dirty buffer which should be on private_list but it isn't. This race has not been reported, probably because most (but not all) callers of mark_buffer_dirty_inode() hold i_mutex and thus are serialized with fsync(). Fix these issues by not clearing b_assoc_map when fsync_buffers_list() moves buffer to a dedicated list and by reinserting buffer in private_list when it is found dirty after we have submitted buffer for IO. We also change the tests whether a buffer is on a private list from !list_empty(&bh->b_assoc_buffers) to bh->b_assoc_map so that they are single word reads and hence lockless checks are safe.

Following the deprecation schedule the a.out ELF interpreter support is removed now with this patch. a.out ELF interpreters were an transition feature for moving a.out systems to ELF, but they're unlikely to be still needed. Pure a.out systems will still work of course. This allows to simplify the hairy ELF loader.
