* target: Propigate up ->cmd_kref put return via transport_generic_free_cmdNicholas Bellinger2013-05-312-14/+16
| | | | | | | | | | | | Go ahead and propigate up the ->cmd_kref put return value from target_put_sess_cmd() -> transport_release_cmd() -> transport_put_cmd() -> transport_generic_free_cmd(). This is useful for certain fabrics when determining the active I/O shutdown case with SCF_ACK_KREF where a final target_put_sess_cmd() is still required by the caller.

* iscsi-target: fix heap buffer overflow on errorKees Cook2013-05-312-6/+6
| | | | | | | | | | | | | | | | If a key was larger than 64 bytes, as checked by iscsi_check_key(), the error response packet, generated by iscsi_add_notunderstood_response(), would still attempt to copy the entire key into the packet, overflowing the structure on the heap. Remote preauthentication kernel memory corruption was possible if a target was configured and listening on the network.

* target/file: Fix off-by-one READ_CAPACITY bug for !S_ISBLK exportNicholas Bellinger2013-05-311-5/+6
| | | | | | | | | | | | | | | | This patch fixes a bug where FILEIO was incorrectly reporting the number of logical blocks (+ 1) when using non struct block_device export mode. It changes fd_get_blocks() to follow all other backend ->get_blocks() cases, and reduces the calculated dev_size by one dev->dev_attrib.block_size number of bytes, and also fixes initial fd_block_size assignment at fd_configure_device() time introduced in commit 0fd97ccf4.

* ib_srpt: Call target_sess_cmd_list_set_waiting during shutdown_sessionNicholas Bellinger2013-05-302-8/+25
| | | | | | | | | | | | | | | | | Given that srpt_release_channel_work() calls target_wait_for_sess_cmds() to allow outstanding se_cmd_t->cmd_kref a change to complete, the call to perform target_sess_cmd_list_set_waiting() needs to happen in srpt_shutdown_session() Also, this patch adds an explicit call to srpt_shutdown_session() within srpt_drain_channel() so that target_sess_cmd_list_set_waiting() will be called in the cases where TFO->shutdown_session() is not triggered directly by TCM.

* target: Re-instate sess_wait_list for target_wait_for_sess_cmdsNicholas Bellinger2013-05-302-4/+15
| | | | | | | | | | | | | | | | | | | | | | | | | Switch back to pre commit 1c7b13fe652 list splicing logic for active I/O shutdown with tcm_qla2xxx + ib_srpt fabrics. The original commit was done under the incorrect assumption that it's safe to walk se_sess->sess_cmd_list unprotected in target_wait_for_sess_cmds() after sess->sess_tearing_down = 1 has been set by target_sess_cmd_list_set_waiting() during session shutdown. So instead of adding sess->sess_cmd_lock protection around sess->sess_cmd_list during target_wait_for_sess_cmds(), switch back to sess->sess_wait_list to allow wait_for_completion() + TFO->release_cmd() to occur without having to walk ->sess_cmd_list after the list_splice. Also add a check to exit if target_sess_cmd_list_set_waiting() has already been called, and add a WARN_ON to check for any fabric bug where new se_cmds are added to sess->sess_cmd_list after sess->sess_tearing_down = 1 has already been set.

However, the new variable was marked __initdata, because the main _use_ of this is in an __init routine. However, the bit setting happens from secondary_startup_64(), which is called not only at bootup, but on every secondary CPU start. Including resuming from STR and at CPU hotplug time. So the value cannot be __initdata.

Thus the Device Tree probing code encased within the first check for Platform Data will never executed, causing the driver to fail when DT is enabled. This patch fixes the aforementioned regression by rejigging the probe() semantics to attempt to extract a platform ID from Device Tree if one can not be sourced from platform data. A pointer to GPIO platform data is always passed to the driver now, so there's little point in checking for 'pdata' and executing the DT case if it's not there. The difference between booting with DT and !DT is when booting with DT, plat_id is not populated. Thus, in the DT case we have to use a DT match table in order to find out which platform we're executing on. So, we're changing the semantics here to only use the match table if no plat_id is supplied though platform data.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix detection of the need to resize the dm thin metadata device. The code incorrectly tried to extend the metadata device when it didn't need to due to a merging error with patch 24347e9 ("dm thin: detect metadata device resizing"). device-mapper: transaction manager: couldn't open metadata space map device-mapper: thin metadata: tm_open_with_sm failed device-mapper: thin: aborting transaction failed device-mapper: thin: switching pool to failure mode Signed-off-by: Alasdair G Kergon <agk@redhat.com>

Alexandre Oliva discovered some problems with how our error handling was interacting with the block layer and for now has disabled our partial handling of sub-page writes. The real sub-page work is in a series of patches from IBM that we still need to integrate and test. The code Alexandre has turned off was really incomplete. Josef has more error handling fixes and an important fix for the new skinny extent format. This also has my fix for the tracepoint crash from late in 3.9. It's the first stage in a larger clean up to get rid of btrfs_bio and make a proper bioset for all the items we need to tack into the bio. For now the bioset only holds our mirror_num and stripe_index, but for the next merge window I'll shuffle more in." * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs: (25 commits) Btrfs: use a btrfs bioset instead of abusing bio internals Btrfs: make sure roots are assigned before freeing their nodes Btrfs: explicitly use global_block_rsv for quota_tree btrfs: do away with non-whole_page extent I/O Btrfs: don't invoke btrfs_invalidate_inodes() in the spin lock context Btrfs: remove BUG_ON() in btrfs_read_fs_tree_no_radix() Btrfs: pause the space balance when remounting to R/O Btrfs: fix unprotected root node of the subvolume's inode rb-tree Btrfs: fix accessing a freed tree root Btrfs: return errno if possible when we fail to allocate memory Btrfs: update the global reserve if it is empty Btrfs: don't steal the reserved space from the global reserve if their space type is different Btrfs: optimize the error handle of use_block_rsv() Btrfs: don't use global block reservation for inode cache truncation Btrfs: don't abort the current transaction if there is no enough space for inode cache Correct allowed raid levels on balance.

| | * | | Btrfs: make sure roots are assigned before freeing their nodesJosef Bacik2013-05-181-18/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If we fail to load the chunk tree we'll call free_root_pointers, except we may not have assigned the roots for the dev_root/extent_root/csum_root yet, so we could NULL pointer deref at this point. Just add checks to make sure these roots are set to keep us from panicing. Thanks, Signed-off-by: Josef Bacik <jbacik@fusionio.com>
| | * | | Btrfs: explicitly use global_block_rsv for quota_treeStefan Behrens2013-05-181-0/+2

In fact, use_block_rsv() which is used in btrfs_cow_block() falls back to the global_block_rsv in this case. But just in order to make it more clear what is happening, change it to explicitly use the global_block_rsv.

This would cause the read to unlock only part of the file range associated with the page, which would in turn leave the entire page locked, which would not only keep the process blocked instead of returning -EIO to it, but also prevent any further access to the file. It turns out that btrfs always issues whole-page reads and writes. The special handling of non-whole_page appears to be a mistake or a left-over from a time when this wasn't the case. Indeed, end_bio_extent_writepage distinguished between whole_page and non-whole_page writes but behaved identically in both cases! I've replaced the whole_page computations with warnings, just to be sure that we're not issuing partial page reads or writes. The warnings should probably just go away some time.
