* [PATCH] Add epoll compat_ code to fs/compat.cDavide Libenzi2007-03-081-0/+100
| | | | | | | | | | | | | | | | | | | | | | | | IA64 and ARM-OABI are currently using their own version of epoll compat_ code. An architecture needs epoll_event translation if alignof(u64) in 32 bit mode is different from alignof(u64) in 64 bit mode. If an architecture needs epoll_event translation, it must define struct compat_epoll_event in asm/compat.h and set CONFIG_HAVE_COMPAT_EPOLL_EVENT and use compat_sys_epoll_ctl and compat_sys_epoll_wait. All 64 bit architecture should use compat_sys_epoll_pwait.

| | | | | | | | | | | | | When a given host directory is specified to be mounted both in hostfs=path1 and with mount option -o path2, we should give access to path1/path2, but this does not happen.

* [GFS2] fix hangup when multiple processes are trying to write to the same fileJosef Whiter2007-03-071-2/+5
| | | | | | | | | | | | | | | | | | This fixes a problem I encountered while running bonnie++. When you have one thread that opens a file and starts to write to it, and then another thread that tries to open and write to the same file, the second thread will loop forever trying to grab the inode lock for that inode. Basically we come in through generic_buffered_file_write, which calls gfs2_prepare_write, which then attempts to grab the glock. Because we don't own the lock, gfs2_prepare_write gets GLR_TRYFAILED, which returns AOP_TRUNCATED_PAGE to generic_buffered_file_write. At this point generic_buffered_file_write loops around again and immediately retries the prepare_write. This means that the second process never gets off of the processor in order to allow the process that holds the lock to finish its work and let go of the lock. This patch makes gfs2_glock_nq schedule() if it gets back a GLR_TRYFAILED, which resolves this problem.

| | | | | | | | | | | | | | Suspend deadlocks when trying to unregister /sys/block/sr0. This comes from Oliver's commit 94bebf4d1b8e7719f0f3944c037a21cfd99a4af7 "Driver core: fix race in sysfs between sysfs_remove_file() and read()/write()". sysfs_write_file downs buffer->sem while calling flush_write_buffer, and flushing that particular write buffer entails downing buffer->sem in orphan_all_buffers, resulting in the obvious self-deadlock.

* | [PATCH] ext[34]: EA block reference count racing fixMingming Cao2007-03-012-32/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are race issues around ext[34] xattr block release code. ext[34]_xattr_release_block() checks the reference count of xattr block (h_refcount) and frees that xattr block if it is the last one reference it. Unlike ext2, the check of this counter is unprotected by any lock. ext[34]_xattr_release_block() will free the mb_cache entry before freeing that xattr block. There is a small window between the check for the re h_refcount ==1 and the call to mb_cache_entry_free(). During this small window another inode might find this xattr block from the mbcache and reuse it, racing a refcount updates. The xattr block will later be freed by the first inode without notice other inode is still use it. Later if that block is reallocated as a datablock for other file, then more serious problem might happen. We need put a lock around places checking the refount as well to avoid racing issue. Another place need this kind of protection is in ext3_xattr_block_set(), where it will modify the xattr block content in- the-fly if the refcount is 1 (means it's the only inode reference it). This will also fix another issue: the xattr block may not get freed at all if no lock is to protect the refcount check at the release time. It is possible that the last two inodes could release the shared xattr block at the same time. But both of them think they are not the last one so only decreased the h_refcount without freeing xattr block at all. We need to call lock_buffer() after ext3_journal_get_write_access() to avoid deadlock (because the later will call lock_buffer()/unlock_buffer () as well).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | atime flag was also overwritten. Noticed by Shirish when he was debugging an atime problem. Should help performance a bit too. cifs should be getting time stamps from the server (that was the original intent too) Signed-off-by: Steve French <sfrench@us.ibm.com>
