2011-01-20cifs: wait indefinitely for responsesJeff Layton1-93/+17
The client should not be timing out on individual SMB requests. Too much of the state between client and server is tied to the state of the socket. If we time out requests and issue spurious disconnects then that comprimises data integrity. Instead of doing this complicated dance where we try to decide how long to wait for a response for particular requests, have the client instead wait indefinitely for a response. Also, use a TASK_KILLABLE sleep here so that fatal signals will break out of this waiting. Later patches will add support for detecting dead peers and forcing reconnects based on that.

2011-01-19cifs: move locked sections out of DeleteMidQEntry and AllocMidQEntryJeff Layton1-17/+24
In later patches, we're going to need to have finer-grained control over the addition and removal of these structs from the pending_mid_q and we'll need to be able to call the destructor while holding the spinlock. Move the locked sections out of both routines and into the callers. Fix up current callers of DeleteMidQEntry to call a new routine that dequeues the entry and then destroys it.

It's an atomic_t and the code accesses the "counter" field in it directly instead of using atomic_read(). It also is sometimes accessed under a spinlock and sometimes not.

2011-01-19cifs: don't fail writepages on -EAGAIN errorsJeff Layton1-12/+37
If CIFSSMBWrite2 returns -EAGAIN, then the error should be considered temporary. CIFS should retry the write instead of setting an error on the mapping and returning. For WB_SYNC_ALL, just retry the write immediately. In the WB_SYNC_NONE case, call redirty_page_for_writeback on all of the pages that didn't get written out and then move on. Also, fix up the handling of a short write with a successful return code. MS-CIFS says that 0 bytes_written means ENOSPC or EFBIG. It doesn't mention what a short, but non-zero write means, so for now treat it as we would an -EAGAIN return.

Linus reported that the RCU lockdep annotation bits triggered for this rcu_dereference() because we're not holding rcu_read_lock(). Going over the code I cannot convince myself its correct: - holding a ref on the parent_ctx, doesn't avoid it being uncloned concurrently (as the comment says), so we can race with a free. - holding parent_ctx->mutex doesn't avoid the above free from taking place either, it would at best avoid parent_ctx from being freed. I.e. the warning is correct. To fix the bug, serialize against the unclone_ctx() call by extending the reach of the parent_ctx->lock.

2011-01-18x86: Make relocatable kernel work with new binutilsShaohua Li1-2/+9
The CONFIG_RELOCATABLE=y option is broken with new binutils, which will make boot panic. According to Lu Hongjiu, the affected binutils are from 2.20.51.0.12 to 2.21.51.0.3, which are release since Oct 22 this year. At least ubuntu 10.10 is using such binutils. See: http://sourceware.org/bugzilla/show_bug.cgi?id=12327 The reason of the boot panic is that we have 'jiffies = jiffies_64;' in vmlinux.lds.S. The jiffies isn't in any section. In kernel build, there is warning saying jiffies is an absolute address and can't be relocatable. At runtime, jiffies will have virtual address 0.

The latter is called only when both ino and dentry are about to be freed, so cleaning ->d_fsdata and ->dentry is pointless. Acked-by: Ian Kent <raven@themaw.net> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
