| | | | | | | | | | | | | | | | error. The final sentence should read "*without* CTF data". The in-kernel CTF parser caches the result of its first attempt to parse CTF data from a module. On subsequent attempts to retrieve CTF data for a module, return an error if there no CTF data. This fixes a panic if you try to enable fbt probes on a module with CTF data twice.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | As it turns out, r186347 actually is insufficient to avoid the use of the curthread-accessing part of mtx_{,un}lock(9) when using a r210623-style curthread implementation on sparc64, crashing the kernel in its early cycles as PCPU isn't set up, yet (and can't be set up as OFW is one of the things we need for that, which leads to a chicken-and-egg problem). What happens is that due to the fact that the idea of r210623 actually is to allow the compiler to cache invocations of curthread, it factors out obtaining curthread needed for both mtx_lock(9) and mtx_unlock(9) to before the branch based on kobj_mutex_inited when compiling the kernel without the debugging options. So change kobj_class_compile_static(9) to just never acquire kobj_mtx, effectively restricting it to its documented use, and add a kobj_init_static(9) for initializing objects using a class compiled with the former and that also avoids using mutex(9) (and malloc(9)). Also assert in both of these functions that they are used in their intended way only. While at it, inline kobj_register_method() and kobj_unregister_method() as there wasn't much point for factoring them out in the first place and so that a reader of the code has to figure out the locking for fewer functions missing a KOBJ_ASSERT.

This bug could lead to NULL pointer reference and resets during boot. r226553: Always pass data size for checksum verification function, as using physical block size declared in bp may not always be what we want.

What is being verified by the script: - Does the pool exist? - Does it have bootfs property configured? - Is mountpoint property of the boot dataset set to 'legacy'? Dataset configured in bootfs property has to be mounted to perform more checks: - Does the /boot directory in boot dataset exist? - Is this dataset configured as root file system in /etc/fstab or set in vfs.root.mountfrom variable in /boot/loader.conf? By using zfsboottest tool the script will read all the files in /boot directory using ZFS boot code and calculate their checksums. Then, it will walk /boot directory using find(1) though regular file sytem and also read all the files in /boot directory and calculate their checksums. If any of the files cannot be looked up, read or checksum is invalid it will be reported and booting off of this pool is probably not possible. Some additional checks may be interesting as well. For example if the disks contain proper pmbr and gptzfsboot code or if all expected files in /boot/ are present. When upgrading FreeBSD, one should snapshot datasets that contain operating system, upgrade (install new world and kernel) and use zfsboottest.sh to verify if it will be possible to boot from new configuration. If all is good one should upgrade boot blocks, by eg.: # gpart -b /boot/pmbr -p /boot/gptzfsboot -i 1 ada1 If something is wrong, one should rollback datasets and report the problems.

| | | | | | | | | | | | | | | | | | | | | | | | | | Both a crash reported on freebsd-current on Oct. 18 under the subject heading "mtx_lock() of destroyed mutex on NFS" and PR# 156168 appear to be caused by clnt_dg_destroy() closing down the socket prematurely. When to close down the socket is controlled by a reference count (cs_refs), but clnt_dg_create() checks for sb_upcall being non-NULL to decide if a new socket is needed. I believe the crashes were caused by the following race: clnt_dg_destroy() finds cs_refs == 0 and decides to delete socket clnt_dg_destroy() then loses race with clnt_dg_create() for acquisition of the SOCKBUF_LOCK() clnt_dg_create() finds sb_upcall != NULL and increments cs_refs to 1 clnt_dg_destroy() then acquires SOCKBUF_LOCK(), sets sb_upcall to NULL and destroys socket This patch fixes the above race by changing clnt_dg_destroy() so that it acquires SOCKBUF_LOCK() before testing cs_refs.

| | | | | | | | | | | | | | | | | | | | | | | Whenever you boot with nfsv4_server_enable=NO (the default) in rc.conf, the /etc/rc.d/nfsd script sets vfs.nfsd.server_max_nfsvers to 3. Then, when you set nfsv4_server_enable=YES in rc.conf, and restart nfsd via the rc.d script, without rebooting, the sysctl does *not* get reset to max version 4, so NFSv4 still doesn't work. Fix this by explicitly setting vfs.nfsd.server_max_nfsvers to 4 when NFSv4 is requested. I also added resetting of the nfs_privport sysctls, since this has the same issue: nfs_reserved_port_only=YES in rc.conf sets the nfs_privport sysctl to 1, but in the other case, the sysctl doesn't get reset to 0.

While here, change drvsize() to only pass the 1.1 version of the structure and not request device path information. If we want device path information you have to set the length of the device path information as an input (along with probably checking the actual EDD version to see which size one should use as the device path information is variable-length). This fixes data smashing problems from passing an EDD 3 structure to BIOSes supporting EDD 4. Approved by: re (kib) Notes: svn path=/stable/9/; revision=227400
