* [AF_PACKET]: Convert PACKET_MMAP over to vm_insert_page().David S. Miller2005-12-06
| | | | | | | | | So we can properly use __GFP_COMP and avoid the use of PG_reserved pages. With extremely helpful review from Hugh Dickins. Signed-off-by: David S. Miller <davem@davemloft.net>
* [TCP] Vegas: timestamp before cloneDavid S. Miller2005-12-06
| | | | | | | | | | | | | We have to store the congestion control timestamp on the SKB before we clone it, not after. Else we get no timestamping information at all. tcp_transmit_skb() has been reworked so that we can do the timestamp still in one spot, instead of at all the call sites. Problem discovered, and initial fix, from Tom Young <tyo@ee.unimelb.edu.au>. Signed-off-by: David S. Miller <davem@davemloft.net>
* [TCP] Vegas: Remove extra call to tcp_vegas_rtt_calcThomas Young2005-12-06

* [NET]: make function pointer argument parseable by kernel-docMartin Waitz2005-12-05

* [NETFILTER]: Fix unbalanced read_unlock_bh in ctnetlinkPatrick McHardy2005-12-05
| | | | | | | | | NFA_NEST calls NFA_PUT which jumps to nfattr_failure if the skb has no room left. We call read_unlock_bh at nfattr_failure for the NFA_PUT inside the locked section, so move NFA_NEST inside the locked section too.

* [NETFILTER]: Fix ip_conntrack_flush abuse in ctnetlinkPatrick McHardy2005-12-05
| | | | | | | | | | | ip_conntrack_flush() used to be part of ip_conntrack_cleanup(), which needs to drop _all_ references on module unload. Table flushed using ctnetlink just needs to clean the table and doesn't need to flush the event cache or wait for any references attached to skbs. Move everything but pure table flushing back to ip_conntrack_cleanup(). Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

* Linux v2.6.15-rc5v2.6.15-rc5Linus Torvalds2005-12-04
| | | | | | | | | | | | | | | | Hey, for no other reason than the fact that I'll be off-line for a week. Of course, I could force everybody to just use git (and when I'm emperor of the world, don't think I won't!), but it seems some people want to just test official releases. Even if they are just -rc's. By the time I'm back, Andrew will have fixed all my bugs, and I'll release it as 2.6.15 and take all the credit. Mwahahahaaa Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* Link USB drivers later in the kernelLinus Torvalds2005-12-03
| | | | | | | | | | | | We want to link the "regular" SCSI drivers before the USB storage driver, since historically we've always detected internal SCSI disks before the external USB storage modules. The link order matters for initcall ordering, and this got broken by mistake by commit 7586269c0b52970f60bb69fcb86e765fc1d72309 which moved the USB host controller PCI quirk handling around.

* Make vm_insert_page() available to NVidia moduleLinus Torvalds2005-12-03
| | | | | | | | It used to use remap_pfn_range(), which wasn't GPL-only either, and the new interface is actually simpler and does more checking, so we shouldn't unnecessarily discourage people from switching over. Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] Fix up per-cpu page batch sizesNick Piggin2005-12-03

* SUNRPC: Fix Oopsable condition in rpc_pipefsTrond Myklebust2005-12-03
| | | | | | | | | | The elements on rpci->in_upcall are tracked by the filp->private_data, which will ensure that they get released when the file is closed. The exception is if rpc_close_pipes() gets called first, since that sets rpci->ops to NULL. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
* NFS: Fix a few further cache consistency regressionsTrond Myklebust2005-12-03
| | | | | | | | | | | | | | | | | | | | | | | | | | Steve Dickson writes: Doing the following: 1. On server: $ mkdir ~/t $ echo Hello > ~/t/tmp 2. On client, wait for a string to appear in this file: $ until grep -q foo t/tmp ; do echo -n . ; sleep 1 ; done 3. On server, create a *new* file with the same name containing that string: $ mv ~/t/tmp ~/t/tmp.old; echo foo > ~/t/tmp will show how the client will never (and I mean never ;-) ) see the updated file. The problem is that we do not update nfsi->cache_change_attribute when the file changes on the server (we only update it when our client makes the changes). This again means that functions like nfs_check_verifier() will fail to register when the parent directory has changed and should trigger a dentry lookup revalidation.

The fix is to only accept the report if is was sent to a multicast or unicast address. Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | sg's st_map_user_pages is modelled on an earlier version of st's sgl_map_user_pages, and has the same bug: if get_user_pages got some but not all of the pages, then those got were released, but the positive res code returned implied that they were still to be freed.

| * [SCSI] sg and st unmap_user_pages allow PageReservedHugh Dickins2005-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 2.6.15-rc1 made sg's st_unmap_user_pages and st's sgl_unmap_user_pages BUG on a PageReserved page. But that's wrong: they could be unmapping the ZERO_PAGE, which is marked PG_reserved; and perhaps others (while get_user_pages is still permitted on VM_PFNMAP areas - that may change). More change is needed here: sg claims to dirty even pages written from, and st claims not to dirty even pages read into; and SetPageDirty is not adequate for this nowadays. Fixes to those follow in a later patch: for the moment just fix the 2.6.15 regression.

| * [SCSI] st: fix a bug in sgl_map_user_pages failure path Hugh Dickins2005-12-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Nick and I had already been looking at drivers/scsi/{sg.c,st.c}, brought there by __put_page in sg.c's peculiar sg_rb_correct4mmap, which we'd like to remove. But that's irrelevant to your pain, except... One extract from the patches I'd like to send Doug and Kai for 2.6.15 or 2.6.16 is this below: since the incomplete get_user_pages path omits to reset res, but has already released all the pages, it will result in premature freeing of user pages, and behaviour just like you've seen. Though I'd have thought incomplete get_user_pages was an exceptional case, and a bit surprised you'd encounter it. Perhaps there's some other premature freeing in the driver, and this instance has nothing whatever to do with it. If the problem were easily reproducible, it'd be great if you could try this patch; but I think you've said it's not :-( Signed-off-by: Kai Makisara <kai.makisara@kolumbus.fi> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

| | | | | | | | | | | | | | | | | | | | | | Some SCSI devices apparently get very confused if we try to use the echo buffer on a non-DT negotiated bus (this mirrors the problems of using PPR on non-LVD for some devices). The fix is to be far more conservative about when we use an echo buffer. With this patch, we'll now see what parameters are negotiated by the read only test, and only look for an echo buffer if DT is negotiated.

| * [SCSI] aic7xxx: reset handler selects a wrong commandVasily Averin2005-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To transport scsi reset command to device aic7xxx reset handler looks at the driver's pending_list and searches any proper command. However the search condition has been inverted: ahc_match_scb() returns TRUE if a matched command is found. As a result the reset on required devices did not turn out well, a correctly working neighbour device may be surprised by the reset. aic7xxx reset handler reports about the success, but really the original situation is not corrected yet.
