* Implement database to workaround misreported physical sector sizesRichard Yao2013-08-221-4/+129
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This implements vdev_bdev_database_check(). It alters the detected sector size of any device listed in a database of drives known to lie about their physical sector sizes. This is based on "6931570 Add flash devices' VID/PID to disk table to advertising 4K physical sector size" from Open Solaris and on sg_simple4.c from sg3_utils. About two dozen lines are taken from sg_simple4.c, which is GPLv2 licensed. However, sg_simple4.c is analogous to a Hello World program and is safe for us to use. We requested that Douglas Gilbert, the author of sg_simple4.c, confirm that this is the case. A cutdown version of his response is as follows: ``` I would consider a SCSI INQUIRY example using the Linux sg driver interface (also written by me) as the equivalent of an "hello world" program in C. ``` The database was created with the help of the freenode and ZFSOnLinux communities. Some notes: 1. The following drives both were confirmed to lie via reports in IRC and they contain capacity information in their identifiers: INTEL SSDSA2M080 INTEL SSDSA2M160 M4-CT256M4SSD2 WDC WD15EARS-00S WDC WD15EARS-00Z WDC WD20EARS-00M The identifiers for different capacity models were extrapolated and added under the assumption that those models also lie. Google was used to verify that the extrapolated drive identifiers existed prior to their inclusion. 2. The OCZ-VERTEX2 3.5 identifer applies to two drives that differ solely in page size (and slightly in capacity). One uses 4096-byte pages and the other uses 8192-byte pages. Both are set to use 8192-byte pages. We could detect the page size by checking the capacity, but that would unnecessarily complicate the code. 3. It is possible for updated drive firmware to correctly report the sector size. There were reports of a few advanced format drives doing that. One report stated that the vendor changed the identification string while another was unclear on this. Both reports involved WDC models. 4. Google was used to determine the size of pages in the listed flash devices. Reports of 8192-byte pages took precedence over reports of 4096-byte pages. 5. Devices behind USB adapters can have their identification strings altered. Identification strings obtained across USB adapters are omitted and no attempt is made to correct for alterations made by USB adapters when doing comparisons against the database. Two entries in the Open Solaris database that appear to have been altered by a USB adapter were omitted.

* Don't leak mount flags into kernelNed Bass2013-06-181-9/+0
| | | | | | | | | | | | | | | | | | | | | | | | When calling mount(), care must be taken to avoid passing in flags that are used only by the user space utilities. Otherwise we may stomp on flags that are reserved for other purposes in the kernel. In particular, openSUSE 12.3 kernels have added a new MS_RICHACL super-block flag whose value conflicts with our MS_COMMENT flag. This causes incorrect behavior such as the umask being ignored. The MS_COMMENT flag essentially serves as a placeholder in the option_map data structure of zfs_mount.c, but its value is never used. Therefore we can avoid the conflict by defining it to 0. The MS_USERS, MS_OWNER, and MS_GROUP flags also conflict with reserved flags in the kernel. While this is not known to have caused any problems, it is nevertheless incorrect. For the purposes of the mount.zfs helper, the "users", "owner", and "group" options just serve as hints to set additional implied options. Therefore we now define their associated mount flags in terms of the options that they imply rather than giving them unique values. Signed-off-by: Brian Behlendorf <[email protected]> Closes #1457

For consistenty with the vdev_disk.c code the upstream version leverages the Illumos bio interfaces. This makes sense for Illumos but not for ZoL for two reasons. 1) The vdev_disk.c code in ZoL has been rewritten to use the Linux block device interfaces which differ significantly from those in Illumos. Therefore, updating the vdev_file.c to use the Illumos interfaces doesn't get you consistency with vdev_disk.c. 2) Using the upstream patch as is would requiring implementing compatibility code for those Solaris block device interfaces in user and kernel space. That additional complexity could lead to confusion and doesn't buy us anything. For these reasons I've opted to simply move the existing vn_rdwr() as is in to the taskq function. This has the advantage of being low risk and easy to understand. Moving the vn_rdwr() function in to its own taskq thread also neatly avoids the possibility of a stack overflow. Finally, because of the additional work which is being handled by the free taskq the number of threads has been increased. The thread count under Illumos defaults to 100 but was decreased to 2 in commit 08d08e due to contention. We increase it to 8 until the contention can be address by porting Illumos #3581.

* Constify structures containing function pointersRichard Yao2013-03-041-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PaX team modified the kernel's modpost to report writeable function pointers as section mismatches because they are potential exploit targets. We could ignore the warnings, but their presence can obscure actual issues. Proper const correctness can also catch programming mistakes. Building the kernel modules against a PaX/GrSecurity patched Linux 3.4.2 kernel reports 133 section mismatches prior to this patch. This patch eliminates 130 of them. The quantity of writeable function pointers eliminated by constifying each structure is as follows: vdev_opts_t 52 zil_replay_func_t 24 zio_compress_info_t 24 zio_checksum_info_t 9 space_map_ops_t 7 arc_byteswap_func_t 5 The remaining 3 writeable function pointers cannot be addressed by this patch. 2 of them are in zpl_fs_type. The kernel's sget function requires that this be non-const. The final writeable function pointer is created by SPL_SHRINKER_DECLARE. The kernel's set_shrinker() and remove_shrinker() functions also require that this be non-const.

* Fix hot sparesBrian Behlendorf2013-03-011-79/+101
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The issue with hot spares in ZoL is because it opens all leaf vdevs exclusively (O_EXCL). On Linux, exclusive opens cause subsequent exclusive opens to fail with EBUSY. This could be resolved by not opening any of the devices exclusively, which is what Illumos does, but the additional protection offered by exclusive opens is desirable. It cleanly prevents you from accidentally adding an in-use non-ZFS device to your pool. To fix this we very slightly relaxed the usage of O_EXCL in the following ways. 1) Functions which open the device but only read had the O_EXCL flag removed and were updated to use O_RDONLY. 2) A common holder was added to the vdev disk code. This allow the ZFS code to internally open the device multiple times but non-ZFS callers may not. 3) An exception was added to make_disks() for hot spare when creating partition tables. For hot spare devices which are already opened exclusively we skip creating the partition table because this must already have been done when the disk was originally added as a hot spare. Additional minor changes include fixing check_in_use() to use a partition instead of a slice suffix. And is_spare() was moved above make_disks() to avoid adding a forward reference.

* Allow fake mounts to succeed on non-legacy filesystems.Will Rouesnel2013-01-071-1/+2
| | | | | | | | | | | | | mountall in Debian depends on being able to pass the -f parameter to mount, which specifies a fake mount and just updates the mtab. Currently mount.zfs will fail such a request if it is not passed with -o zfsutil. This patch allows a fake mount on a non-legacy filesystem to succeed in the same manner as a -o remount does, thus enabling mountall to work correctly.

* vdev_id support for device link aliasesNed Bass2012-12-031-142/+215
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a vdev_id feature to map device names based on already defined udev device links. To increase the odds that vdev_id will run after the rules it depends on, increase the vdev.rules rule number from 60 to 69. With this change, vdev_id now provides functionality analogous to zpool_id and zpool_layout, paving the way to retire those tools. A defined alias takes precedence over a topology-derived name, but the two naming methods can otherwise coexist. For example, one might name drives in a JBOD with the sas_direct topology while naming an internal L2ARC device with an alias. For example, the following lines in vdev_id.conf will result in the creation of links /dev/disk/by-vdev/{d1,d2}, each pointing to the same target as the device link specified in the third field. # by-vdev # name fully qualified or base name of device link alias d1 /dev/disk/by-id/wwn-0x5000c5002de3b9ca alias d2 wwn-0x5000c5002def789e Also perform some minor vdev_id cleanup, such as removal of the unused -s command line option.

* vdev_id fails to handle complex device topologiesCyril Plisko2012-11-291-4/+4
| | | | | | | | | | | | While expanding positional parameters shell requires non-single digits to be enclosed in braces. When the SAS topology is non-trivial the number of positional parameters generated internally by vdev_id script (using set -- ...) easily crosses single digit limit and vdev_id fails to generate links.

* Make vdev_id POSIX sh compatibleNed Bass2012-11-271-16/+23
| | | | | | | | | | | Full bash may not be available in all environments where udev helpers run, such as in an initial ramdisk. To avoid breakage in this case, remove use of bash-specific features such as variable arrays and the `declare' keyword from the vdev_id script.

| | | | | | | | | | | | | | | | Canonicalize the mount point passed to the mount.zfs helper. This way a clean path is always added to mtab which ensures the umount can properly locate and remove the entry. Test case: $ mkdir /mnt/foo $ mount -t zfs zpool/foo /mnt/../mnt/foo//// $ umount /mnt/foo $ cat /etc/mtab | grep zpool/foo zpool/foo /mnt/../mnt/foo//// zfs rw 0 0 Signed-off-by: Brian Behlendorf <[email protected]> Closes #573
