* Mark functions as staticArvind Sankar2020-06-181-1/+1
| | | | | | | | | | | Mark functions used only in the same translation unit as static. This only includes functions that do not have a prototype in a header file either.

* Multiple DVA Scrubbing FixTom Caputi2019-03-151-14/+109
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, there is an issue in the sequential scrub code which prevents self healing from working in some cases. The scrub code will split up all DVA copies of a bp and issue each of them separately. The problem is that, since each of the DVAs is no longer associated with the others, the self healing code doesn't have the opportunity to repair problems that show up in one of the DVAs with the data from the others. This patch fixes this issue by ensuring that all IOs issued by the sequential scrub code include all DVAs. Initially, only the first DVA of each is attempted. If an issue arises, the IO is retried with all available copies, giving the self healing code a chance to correct the issue. To test this change, this patch also adds the ability for zinject to specify individual DVAs to inject read errors into. We then add a new test case that utilizes this functionality to ensure scrubs and self-healing reads can handle and transparently fix issues with individual copies of blocks.

| | | | | | | | | | | Adds a libzutil for utility functions that are common to libzfs and libzpool consumers (most of what was in libzfs_import.c).

* OpenZFS 9403 - assertion failed in arc_buf_destroy()Tom Caputi2018-08-291-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Assertion failed in arc_buf_destroy() when concurrently reading block with checksum error. Porting notes: * The ability to zinject decompression errors has been added, but this only works at the zio_decompress() level, where we have all of the info we need to match against the user's zinject options. * The decompress_fault test has been added to test the new zinject functionality * We attempted to set zio_decompress_fail_fraction to (1 << 18) in ztest for further test coverage. Although this did uncover a few low priority issues, this unfortuantely also causes ztest to ASSERT in many locations where the code is working correctly since it is designed to fail on IO errors. Developers can manually set this variable with the '-o' option to find and debug issues.

* Add support for decryption faults in zinjectTom Caputi2018-05-021-6/+26
| | | | | | | | | | | | | | This patch adds the ability for zinject to trigger decryption and authentication faults in the ZIO and ARC layers. This functionality is exposed via the new "decrypt" error type, which may be provided for "data" object types. This patch also refactors some of the core encryption / decryption functions so that they have consistent prototypes, handle errors consistently, and do not have unused arguments.

* Add corruption failure option to zinject(8)Don Brady2017-08-141-10/+24
| | | | | | | | | | | Added a 'corrupt' error option that will flip a bit in the data after a read operation. This is useful for generating checksum errors at the device layer (in a mirror config for example). It is also used to validate the diagnosis of checksum errors from the zfs diagnosis engine.

To help simulate intermittent error conditions, you can now specify a real number percentage value. This is also very useful for our ZFS fault diagnosis testing and for injecting intermittent errors during load testing.

This avoids the need to implement new compatibility code and allows us to rely on the existing taskq implementation. *) An extern for zfs_txg_synctime_ms was added to sys/dsl_pool.h because declaring externs in source files as was done in the original patch is just plain wrong. *) Instead of panicing the system when the deadman triggers a zevent describing the blocked vdev and the first pending I/O is posted. If the panic behavior is desired Linux provides other generic methods to panic the system when threads are observed to hang. *) For reference, to delay zios by 30 seconds for testing you can use zinject as follows: 'zinject -d <vdev> -D30 <pool>' References: illumos/illumos-gate@283b84606b6fc326692c03273de1774e8c122f9a https://www.illumos.org/issues/3246 Ported-by: Brian Behlendorf <[email protected]> Closes #1396
