* fix a bug in ZFS mirror code for handling multiple DVAaAndriy Gapon2014-01-161-3/+6
| | | | | | | | | | | | | | | | | | | The bug was introduced in r256956 "Improve ZFS N-way mirror read performance". The code in vdev_mirror_dva_select erroneously considers already tried DVAs for the next attempt. Thus, it is possible that a failing DVA would be retried forever. As a secondary effect, if the attempts fail with checksum error, then checksum error reports are accumulated until the original request ultimately fails or succeeds. But because retrying is going on indefinitely the cheksum reports accumulation will effectively be a memory leak.

* zfs: getnewvnode_reserve must be called outside of a zfs transactionAndriy Gapon2014-01-163-2/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | Otherwise we could run into the following deadlock. A thread has a transaction open and assigned to a transaction group. That would prevent the transaction group from be quiesced and synced. The thread is blocked in getnewvnode_reserve waiting for a vnode to a be reclaimed. vnlru thread is blocked trying to enter ZFS VOP because a filesystem is suspended by an ongoing rollback or receive operation. In its turn the operation is waiting for the current transaction group to be synced. zfs_zget is always used outside of active transactions, but zfs_mknode is always used in a transaction context. Thus, we hoist getnewvnode_reserve from zfs_mknode to its callers. While there, assert that ZFS always calls getnewvnode while having a vnode reserved.

* Fix ipfw fwd for IPv4 traffic broken by r249894.Alexander V. Chernikov2014-01-161-0/+8
| | | | | | | | | | | | | | | | | | | Problem case: Original lookup returns route with GW set, so gw points to rte->rt_gateway. After that we're changing dst and performing lookup another time. Since fwd host is most probably directly reachable, resulting rte does not contain rt_gateway, so gw is not set. Finally, we end with packet transmitted to proper interface but wrong link-layer address.

* In the nested TLB fault handler, for a direct-mapped address, makeMarcel Moolenaar2014-01-151-1/+1
| | | | | | | | | | | | | | | | | | sure to clear the lower 12 bits. We're adding the translation attributes to the physical address and non-zero bits in the first 12 bits would give us something unexpected, including invalid bit values. Those trigger nested general protection faults. We do not have to clear the region bits, because they are ignored anyway, so we can replace an existing dep instruction with the one we need. This fixes GP faults for the swapper thread, as it's the only thread that has a direct-mapped stack. Since the bug is in the nested TLB fault handler, the frequency of hitting the GP is in the order of hours/days under load. Notes: svn path=/head/; revision=260666

* sh: Remove SIGWINCH handler and just check for resize before every read.Jilles Tjoelker2014-01-143-23/+3
| | | | | | | | | | | | | | | | The SIGWINCH handler triggers breakage in libedit which is hard to fix; see PR bin/169773. Also, window size changes while a program is in foreground (and it rather than sh will receive SIGWINCH) will now be picked up automatically. Downside: it is now certain that a resize is only processed after pressing <Enter>. If libedit is fixed, sh will most likely have to be changed also.

* Use TAP_TESTS_PERL to register the legacy_test in bin/pax.Julio Merino2014-01-143-11/+1
| | | | | | | | | | | | | | | | | | Redo r260586 by using the new functionality in tap.test.mk to transparently support perl-based test programs. As a side-effect, we get rid of an explicit path to /usr/bin/perl by replacing it with /usr/local/bin/perl (or as defined in tap.test.mk). This also fixes the name of the legacy_test source file because this should have always been legacy_test.pl and not legacy_test.sh. My mistake when originally moving the code around without realizing that this was a perl script. MFC after: 5 days Notes: svn path=/head/; revision=260634
* Support perl-based TAP-compliant test programs.Julio Merino2014-01-141-0/+27
| | | | | | | | | | | | | | | | Introduce a TAP_TESTS_PERL primitive to list test programs written in perl. Only do this in tap.test.mk because I only expect perl-based test programs with this interface. This is very similar to TAP_TESTS_SH but the difference is that we record in the Kyuafile that the test program requires a perl interpreter. This in turn makes Kyua mark the test as skipped if the perl package is not yet installed, instead of mysteriously failing to run the program.

* Support defining test program metadata from the Makefiles.Julio Merino2014-01-141-1/+15
| | | | | | | | | | | | | | | | | | Introduce a new, per-test-program TEST_METADATA.<program> variable that contains a list of key/value paris describing metadata properties for that test program. These properties are later written into the auto-generated Kyuafile when using the KYUAFILE=auto functionality. This is to avoid having to supply hand-crafted Kyuafiles when the needs for metadata overrides are trivial. While doing this, and because I am documenting TEST_METADATA, take the chance to document the TEST_INTERFACE setting as well. MFC after: 5 days Notes: svn path=/head/; revision=260632

| | | | | | | | | | | | | | | | | | can be initiated in the context of a vcpu thread or from the bhyve(8) control process. The first use of this functionality is to update the vlapic trigger-mode register when the IOAPIC pin configuration is changed. Prior to this change we would update the TMR in the virtual-APIC page at the time of interrupt delivery. But this doesn't work with Posted Interrupts because there is no way to program the EOI_exit_bitmap[] in the VMCS of the target at the time of interrupt delivery.

| | | | | | | | | | | | | | standard core target by declaring coreops_suppress_target with initializer. This is also happening for non-cross kgdb, by virtue of having fbsd-threads.c in libgdb and having it do the exact same thing. Since fbsd-threads.c is not included in in libgdb when building a cross debugger, we ended up with more than 1 core file targets (the standard gdb core file target and kgdb's libkvm based core file target) and this behaves the same as not having a core target at all.

| | | | | | | | | | | | | | | one significant difference: for LIB32 builds both TARGET_ARCH and MACHINE_ARCH are defined. TARGET_ARCH confusingly holds the architecture of the host (e.g. amd64), while MACHINE_ARCH holds the architecture were trying to build (e.g. i386). With both set and different, r260022 changed the behaviour to interpret the condition as building a cross-amd64 libkvm on i386, when obviously we're trying to build an i386 version on amd64. When COMPAT_32BIT is defined, we're building LIB32 and ignore the value of TARGET_ARCH as we did before. Notes: svn path=/head/; revision=260599
