2007-04-14ide: use correct IDE error recoverySuleiman Souhlal1-0/+1
ide: use correct IDE error recovery IDE error recovery is using IDLE IMMEDIATE if the drive is busy or has DRQ set. This violates the ATA spec (can only send IDLE IMMEDIATE when drive is not busy) and really hoses up some drives (modern drives will not be able to recover using this error handling). The correct thing to do is issue a SRST followed by a SET FEATURES command. This is what Western Digital recommends for error recovery and what Western Digital says Windows does.  It also does not violate the ATA spec as far as I can tell. Bart: * port the patch over the current tree * undo the recalibration code removal * send SET FEATURES command after checking for good drive status * don't check whether the current request is of REQ_TYPE_ATA_{CMD,TASK} type because we need to send SET FEATURES before handling any requests * some pre-ATA4 drives require INITIALIZE DEVICE PARAMETERS command before other commands (except IDENTIFY) so send SET FEATURES only if there are no pending drive->special requests * update comments and patch description * any bugs introduced by this patch are mine and not Suleiman's :-) Signed-off-by: Suleiman Souhlal <suleiman@google.com> Acked-by: Alan Cox <alan@redhat.com> Cc: Chuck Ebbert <cebbert@redhat.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2007-03-13conntrack: fix {nf, ip}_ct_iterate_cleanup endless loopsPatrick McHardy1-1/+1
[NETFILTER]: conntrack: fix {nf,ip}_ct_iterate_cleanup endless loops Fix {nf,ip}_ct_iterate_cleanup unconfirmed list handling: - unconfirmed entries can not be killed manually, they are removed on confirmation or final destruction of the conntrack entry, which means we might iterate forever without making forward progress. This can happen in combination with the conntrack event cache, which holds a reference to the conntrack entry, which is only released when the packet makes it all the way through the stack or a different packet is handled. - taking references to an unconfirmed entry and using it outside the locked section doesn't work, the list entries are not refcounted and another CPU might already be waiting to destroy the entry What the code really wants to do is make sure the references of the hash table to the selected conntrack entries are released, so they will be destroyed once all references from skbs and the event cache are dropped. Since unconfirmed entries haven't even entered the hash yet, simply mark them as dying and skip confirmation based on that.

2007-03-09ufs: restore back support of openstepEvgeniy Dushistov1-0/+1
This is a fix of regression, which triggered by ~2.6.16. Patch with name ufs-directory-and-page-cache-from-blocks-to-pages.patch: in additional to conversation from block to page cache mechanism added new checks of directory integrity, one of them that directory entry do not across directory chunks. But some kinds of UFS: OpenStep UFS and Apple UFS (looks like these are the same filesystems) have different directory chunk size, then common UFSes(BSD and Solaris UFS). So this patch adds ability to works with variable size of directory chunks, and set it for ufstype=openstep to right size. Tested on darwin ufs.

2007-03-09mmc: Power quirk for ENE controllersDarren Salt1-0/+1
mmc: Power quirk for ENE controllers Support for these devices was broken for 2.6.18-rc1 and later by commit 146ad66eac836c0b976c98f428d73e1f6a75270d, which added voltage level support. This restores the previous behaviour for these devices by ensuring that when the voltage is changed, only one write to set the voltage is performed. It may be that both writes are needed if the voltage is being changed between two non-zero values or that it's safe to ensure that only one write is done if the hardware only supports one voltage; I don't know whether either is the case nor can I test since I have only the one SD reader (1524:0550), and it supports just the one voltage.

2007-03-09Fix recently introduced problem with shutting down a busy NFS server.NeilBrown1-1/+1
When the last thread of nfsd exits, it shuts down all related sockets. It currently uses svc_close_socket to do this, but that only is immediately effective if the socket is not SK_BUSY. If the socket is busy - i.e. if a request has arrived that has not yet been processes - svc_close_socket is not effective and the shutdown process spins. So create a new svc_force_close_socket which removes the SK_BUSY flag is set and then calls svc_close_socket. Also change some open-codes loops in svc_destroy to use list_for_each_entry_safe.

2007-03-09md: Avoid possible BUG_ON in md bitmap handling.Neil Brown1-0/+1
md/bitmap tracks how many active write requests are pending on blocks associated with each bit in the bitmap, so that it knows when it can clear the bit (when count hits zero). The counter has 14 bits of space, so if there are ever more than 16383, we cannot cope. Currently the code just calles BUG_ON as "all" drivers have request queue limits much smaller than this. However is seems that some don't. Apparently some multipath configurations can allow more than 16383 concurrent write requests. So, in this unlikely situation, instead of calling BUG_ON we now wait for the count to drop down a bit. This requires a new wait_queue_head, some waiting code, and a wakeup call. Tested by limiting the counter to 20 instead of 16383 (writes go a lot slower in that case...).

2007-03-09knfsd: Fix a race in closing NFSd connections.NeilBrown1-1/+1
If you lose this race, it can iput a socket inode twice and you get a BUG in fs/inode.c When I added the option for user-space to close a socket, I added some cruft to svc_delete_socket so that I could call that function when closing a socket per user-space request. This was the wrong thing to do. I should have just set SK_CLOSE and let normal mechanisms do the work. Not only wrong, but buggy. The locking is all wrong and it openned up a race where-by a socket could be closed twice. So this patch: Introduces svc_close_socket which sets SK_CLOSE then either leave the close up to a thread, or calls svc_delete_socket if it can get SK_BUSY. Adds a bias to sk_busy which is removed when SK_DEAD is set, This avoid races around shutting down the socket. Changes several 'spin_lock' to 'spin_lock_bh' where the _bh was missing.

This is based on a patch by Eric W. Biederman, who pointed out that pid namespaces are still fake, and we only have one ever active. So for the time being, we can modify any code which could access tsk->nsproxy->pid_ns during task exit to just use &init_pid_ns instead, and move the exit_task_namespaces call in do_exit() back above exit_notify(), so that an exiting nfs server has a valid tsk->sighand to work with.

2007-01-30[PATCH] namespaces: fix exit race by splitting exitSerge E. Hallyn1-11/+19
Fix exit race by splitting the nsproxy putting into two pieces. First piece reduces the nsproxy refcount. If we dropped the last reference, then it puts the mnt_ns, and returns the nsproxy as a hint to the caller. Else it returns NULL. The second piece of exiting task namespaces sets tsk->nsproxy to NULL, and drops the references to other namespaces and frees the nsproxy only if an nsproxy was passed in. A little awkward and should probably be reworked, but hopefully it fixes the NFS oops. Signed-off-by: Serge E.

The apple powerbook people are used to switch the pb_fnmode setting at runtime through writing to sysfs, altering the module parameter value. This was broken for them in 2.6.20-rc1 when generic HID layer was introduced, as the pb_fnmode flag was made per-hiddevice, instead of global variable.

2007-01-27[PATCH] md: fix potential memalloc deadlock in mdNeilBrown1-1/+1
If a GFP_KERNEL allocation is attempted in md while the mddev_lock is held, it is possible for a deadlock to eventuate. This happens if the array was marked 'clean', and the memalloc triggers a write-out to the md device. For the writeout to succeed, the array must be marked 'dirty', and that requires getting the mddev_lock. So, before attempting a GFP_KERNEL allocation while holding the lock, make sure the array is marked 'dirty' (unless it is currently read-only).

2007-01-27[PATCH] knfsd: Fix type mismatch with filldir_t used by nfsdNeilBrown3-9/+7
nfsd defines a type 'encode_dent_fn' which is much like 'filldir_t' except that the first pointer is 'struct readdir_cd *' rather than 'void *'. It then casts encode_dent_fn points to 'filldir_t' as needed. This hides any other type mismatches between the two such as the fact that the 'ino' arg recently changed from ino_t to u64. So: get rid of 'encode_dent_fn', get rid of the cast of the function type, change the first arg of various functions from 'struct readdir_cd *' to 'void *', and live with the fact that we have a little less type checking on the calling of these functions now.

NFSd assumes that largest number of pages that will be needed for a request+response is 2+N where N pages is the size of the largest permitted read/write request. The '2' are 1 for the non-data part of the request, and 1 for the non-data part of the reply. However, when a read request is not page-aligned, and we choose to use ->sendfile to send it directly from the page cache, we may need N+1 pages to hold the whole reply. This can overflow and array and cause an Oops. This patch increases size of the array for holding pages by one and makes sure that entry is NULL when it is not in use.

2007-01-24libata: Initialize qc->pad_lenBrian King1-0/+1
Initialize qc->pad_len for each new command. This ensures that pad_len is not set to a stale value for zero data length commands. Signed-off-by: Brian King <brking@linux.vnet.ibm.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
2007-01-24libata: Fixup n_elem initializationBrian King1-0/+1
Fixup the inialization of qc->n_elem. It currently gets initialized to 1 for commands that do not transfer any data. Fix this by initializing n_elem to 0 and only setting to 1 in ata_scsi_qc_new when there is data to transfer. This fixes some problems seen with SATA devices attached to ipr adapters.

2007-01-24[IP] TUNNEL: Fix to be built with user application.Masahide NAKAMURA1-0/+2
include/linux/if_tunnel.h is broken for user application because it was changed to use __be32 which is required to include linux/types.h in advance but didn't. (This issue is found when building MIPL2 daemon. We are not sure this is the last header to be fixed about __be32.)

2007-01-24[NETFILTER]: Fix iptables ABI breakage on (at least) CRISPatrick McHardy1-1/+1
With the introduction of x_tables we accidentally broke compatibility by defining IPT_TABLE_MAXNAMELEN to XT_FUNCTION_MAXNAMELEN instead of XT_TABLE_MAXNAMELEN, which is two bytes larger. On most architectures it doesn't really matter since we don't have any tables with names that long in the kernel and the structure layout didn't change because of alignment requirements of following members. On CRIS however (and other architectures that don't align data) this changed the structure layout and thus broke compatibility with old iptables binaries. Changing it back will break compatibility with binaries compiled against recent kernels again, but since the breakage has only been there for three releases this seems like the better choice.
