cppcheck: integrete cppcheck In order for cppcheck to perform a proper analysis it needs to be aware of how the sources are compiled (source files, include paths/files, extra defines, etc). All the needed information is available from the Makefiles and can be leveraged with a generic cppcheck Makefile target. So let's add one. Additional minor changes: * Removing the cppcheck-suppressions.txt file. With cppcheck 2.3 and these changes it appears to no longer be needed. Some inline suppressions were also removed since they appear not to be needed. We can add them back if it turns out they're needed for older versions of cppcheck. * Added the ax_count_cpus m4 macro to detect at configure time how many processors are available in order to run multiple cppcheck jobsa * "PHONY =" line moved in to the Rules.am file which is included at the top of all Makefile.am's. This is just convenient becase it allows us to use the += syntax to add phony targets. * One upside of this integration worth mentioning is it now allows `make cppcheck` to be run in any directory to check that subtree. * For the moment, cppcheck is not run against the FreeBSD specific kernel sources. The cppcheck-FreeBSD target will need to be implemented and testing on FreeBSD to support this. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Pull-request: #11508 part 5/5 |

cppcheck: zpool_main.c possible null pointer dereference Explicitly check for NULL to satisfy cppcheck that "val" can never be NULL when passed to printf(). This looks like a false positive since is_blank_str() can never take the false conditional branch when passed a NULL. But there's no harm in adding the extra check.

ZTS: avoid piping to special devices As described in #11445, the kernel interface kernel_{read,write} no longer act on special devices. In the ZTS, zfs send and receive are tested by piping to these devices, leading to spurious failures (for positive tests) and may mask errors (for negative tests). Until a more permanent mechanism to address this deficiency is developed, clean up the output from the ZTS by avoiding directly piping to or from /dev/null and /dev/zero. For /dev/zero input, simply use a pipe: `cat </dev/zero |` . However, for /dev/null output, the shell semantics for pipe failures means that zfs send error codes will be masked by the successful `| cat >/dev/null` command execution. In that case, use a temporary file under $TEST_BASE_DIR for output in favor.

assertion failed in arc_wait_for_eviction() If the system is very low on memory (specifically, `arc_free_memory() < arc_sys_free/2`, i.e. less than 1/16th of RAM free), `arc_evict_state_impl()` will defer wakups. In this case, the arc_evict_waiter_t's remain on the list, even though `arc_evict_count` has been incremented past their `aew_count`. The problem is that `arc_wait_for_eviction()` assumes that if there are waiters on the list, the count they are waiting for has not yet been reached. However, the deferred wakeups may violate this, causing `ASSERT(last->aew_count > arc_evict_count)` to fail. This commit resolves the issue by having new waiters use the greater of `arc_evict_count` and the last `aew_count`.

Speed up "zpool import" in the presence of many zvols By default, FreeBSD does not allow zpools to be backed by zvols (that can be changed with the "vfs.zfs.vol.recursive" sysctl). When that sysctl is set to 0, the kernel does not attempt to read zvols when looking for vdevs. But the zpool command still does. This change brings the zpool command into line with the kernel's behavior. It speeds "zpool import" when an already imported pool has many zvols, or a zvol with many snapshots. https://svnweb.freebsd.org/base?view=revision&revision=357235 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=241083 https://reviews.freebsd.org/D22077 Obtained from: FreeBSD PR: 241083 Reported by: Martin Birgmeier <d8zNeCFG@aon.at> Sponsored by: Axcient Signed-off-by: Alan Somers <asomers@gmail.com> Pull-request: #11502 part 1/1 |

RAIDZ2/3 fails to heal silently corrupted parity w/2+ bad disks When scrubbing, (non-sequential) resilvering, or correcting a checksum error using RAIDZ parity, ZFS should heal any incorrect RAIDZ parity by overwriting it. For example, if P disks are silently corrupted (P being the number of failures tolerated; e.g. RAIDZ2 has P=2), `zpool scrub` should detect and heal all the bad state on these disks, including parity. This way if there is a subsequent failure we are fully protected. With RAIDZ2 or RAIDZ3, a block can have silent damage to a parity sector, and also damage (silent or known) to a data sector. In this case the parity should be healed but it is not. The problem can be noticed by scrubbing the pool twice. Assuming there was no damage concurrent with the scrubs, the first scrub should fix all silent damage, and the second scrub should be "clean" (`zpool status` should not report checksum errors on any disks). If the bug is encountered, then the second scrub will repair the silently-damaged parity that the first scrub failed to repair, and these checksum errors will be reported after the second scrub. Since the first scrub repaired all the damaged data, the bug can not be encountered during the second scrub, so subsequent scrubs (more than two) are not necessary. The root cause of the problem is some code that was inadvertently added to `raidz_parity_verify()` by the DRAID changes. The incorrect code causes the parity healing to be aborted if there is damaged data (`rc_error != 0`) or the data disk is not present (`!rc_tried`). These checks are not necessary, because we only call `raidz_parity_verify()` if we have the correct data (which may have been reconstructed using parity, and which was verified by the checksum). This commit fixes the problem by removing the incorrect checks in `raidz_parity_verify()`. Signed-off-by: Matthew Ahrens <mahrens@delphix.com> Pull-request: #11489 part 1/2 |

ZFS: add mutex protection to metaslab_class_t.mc_historgram The mc_histogram fields were unprotected when that code was first written in "Illumos 4976-4984 - metaslab improvements" (OpenZFS f3a7f6610f2df0217ba3b99099019417a954b673). The lock wasn't added until 3dfb57a35e8cbaa7c424611235d669f3c575ada1, though it's unclear exactly which fields it's supposed to protect. In any case, it wasn't until vdev_load was parallelized that any code attempted concurrent access to those fields. Signed-off-by: Alan Somers <asomers@gmail.com> Pull-request: #11470 part 5/5 |

Parallelize vdev_load metaslab_init is the slowest part of importing a mature pool, and it must be repeated hundreds of times for each top-level vdev. But its speed is dominated by a few serialized disk accesses. That can lead to import times of > 1 hour for pools with many top-level vdevs on spinny disks. Speed up the import by using a taskqueue to parallelize vdev_load across all top-level vdevs. Sponsored by: Axcient Signed-off-by: Alan Somers <asomers@gmail.com> Pull-request: #11470 part 1/5 |
