| * | tile: fix bug in get_user() for 4-byte valuesChris Metcalf2012-06-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The definition of 32-bit values in the 64-bit tilegx architecture is that they should be sign-extended regardless of whether they are considered signed or unsigned by the compiler. Accordingly, we need to use an "ld4s" rather than "ld4u" to load and sign-extend for get_user(). This fixes glibc bug 14238 (see http://sourceware.org/bugzilla), introduced during the 3.5 merge window. Signed-off-by: Chris Metcalf <cmetcalf@tilera.com>

* | | | | swap: fix shmem swapping when more than 8 areasHugh Dickins2012-06-152-11/+9

Whoops. Yes, I blindly followed read_swap_header()'s pte_to_swp_entry( swp_entry_to_pte()) technique for determining maximum usable swap offset, without stopping to realize that that actually depends upon the pte swap encoding shifting swap offset to the higher bits and truncating it there. Whereas our radix_tree swap encoding leaves offset in the lower bits: it's swap "type" (that is, index of swap area) that was truncated. Fix it by reducing the SWP_TYPE_SHIFT() in swapops.h, and removing the broken radix_to_swp_entry(swp_to_radix_entry()) from read_swap_header(). This does not reduce the usable size of a swap area any further, it leaves it as claimed when making the original commit: no change from 3.0 on x86_64, nor on i386 without PAE; but 3.0's 512GB is reduced to 128GB per swapfile on i386 with PAE. It's not a change I would have risked five years ago, but with x86_64 supported for ten years, I believe it's appropriate now. Hmm, and what if some architecture implements its swap pte with offset encoded below type? That would equally break the maximum usable swap offset check. Happily, they all follow the same tradition of encoding offset above type, but I'll prepare a check on that for next.

The nfs client was trying to mount using NFS v0, causing either a BUG() or a protocol not supported message.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is no need to bug the user about the server returning an error on destroy_session. The error will be handled by the state manager, without any need for further input from anyone else. So convert that printk into a debugging dprintk.

| * | | | | | NFSv4: Fix up decode_attr_mdsthresholdTrond Myklebust2012-06-051-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix an incorrect use of 'likely()'. The FATTR4_WORD2_MDSTHRESHOLD bit is only expected in NFSv4.1 OPEN calls, and so is actually rather _unlikely_. decode_attr_mdsthreshold needs to clear FATTR4_WORD2_MDSTHRESHOLD from the attribute bitmap after it has decoded the data.

| * | | | | | NFSv4: Fix an Oops in the open recovery codeTrond Myklebust2012-06-054-6/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The open recovery code does not need to request a new value for the mdsthreshold, and so does not allocate a struct nfs4_threshold. The problem is that encode_getfattr_open() will still request an mdsthreshold, and so we end up Oopsing in decode_attr_mdsthreshold. This patch fixes encode_getfattr_open so that it doesn't request an mdsthreshold when the caller isn't asking for one. It also fixes decode_attr_mdsthreshold so that it errors if the server returns an mdsthreshold that we didn't ask for (instead of Oopsing).
