dtrace causing sigtrap?
Just to let people know what my big picture is, I''m trying to write a script that will let me run a program, and name a progeny of that program that I want to debug. My script should find the first occurrence of that progeny, and run it until it finishes initializing the runtime linker, but stop it before it runs any shared library startup routines. (Failing that, I''d be okay

sysctl_out_proc() race in stable w/ patch
There is a rather serious race with copyout() and process termination in -stable. sysctl_kern_proc() loops through the allproc list writing the results to user memory. If it stalls during the copyout (e.g. the user memory has to take a vm_fault) and the process is ripped out from under it it will go looping into never never land. The solution is very simple, simply

Panic dereferencing p->p_leader during exit1()
My wife got the following from a system running (effectively) 4.8-RELEASE (I built/installed world just before the kernel version was updated from 4.8-RC to 4.8-RELEASE). I gather she made a few attempts to get mozilla to start and then the system panic'd. According to the crashdump, p->p_leader is NULL but according to the code, this can never happen. This is a UP Athlon XP-1800 with

newbie question about a dbuf-arc eviction race
Hi, Can a dbuf be in DB_CACHED state, db_holds == 0, b_efunc != NULL while its db_buf is put on the eviction list ? From an ASSERT in dbuf_do_evict(), it appears that it can. If it can, I am wondering what is preventing the following race dbuf_hold_impl() db = dbuf_find(dn, level, blkid); ... if (db->db_buf && refcount_is_zero(&db->db_holds)) {

still mbuf leak in 9.0 / 9.1?
Hi list, since we activated 10gbe on ixgbe cards + jumbo frames(9k) on 9.0 and now on 9.1 we recognize that after a random period of time, sometimes a week, sometimes only a day, the system doesn't send any packets out. The phenomenon is that you can't login via ssh, nfs and istgt is not operative. Yet you can login on the console and execute commands. A clean shutdown isn't possible

SCSI synchronize cache cmd
Hi, I work on a support team for the Sun StorEdge 6920 and have a question about the use of the SCSI sync cache command in Solaris and ZFS. We have a bug in our 6920 software that exposes us to a memory leak when we receive the SCSI sync cache command: 6456312 - SCSI Synchronize Cache Command is flawed It will take some time for this bug fix to role out to the field so we need to understand

Refactor zfs_zget()
Hi, Since almost all operations in the FUSE low-level API identify files by inode number, I''ve been using zfs_zget() to get the corresponding znode/vnode in order to call the corresponding VFS function in zfs_vnops.c. However, there are some cases when zfs_zget() behaves slightly different than I need: 1) If zp->z_unlinked != 0 then zfs_zget() returns ENOENT. I need it to return

9-STABLE -> NFS -> NetAPP:
I'm running a few servers sitting on top of a NetAPP file server ? everything runs great, but periodically I'm getting: nfs_getpages: error 13 vm_fault: pager read error, pid 11355 (https) errors on my screen ? not always same pid ? the annoying part is that it seems to always affect the same jail that is running .. if I shutdown all jails on that physical server, everything shuts down

gzip compression throttles system?
I just had a quick play with gzip compression on a filesystem and the result was the machine grinding to a halt while copying some large (.wav) files to it from another filesystem in the same pool. The system became very unresponsive, taking several seconds to echo keystrokes. The box is a maxed out AMD QuadFX, so it should have plenty of grunt for this. Comments? Ian

Motherboard for home zfs/solaris file server
Hello, I am building a home file server and am looking for an ATX mother board that will be supported well with OpenSolaris (onboard SATA controller, network, graphics if any, audio, etc). I decided to go for Intel based boards (socket LGA 775) since it seems like power management is better supported with Intel processors and power efficiency is an important factor. After reading several
