Folks, We came across a memory race condition between VPP vhost driver and the kernel vhost. VPP is running a tap interface over vhost backend. In this case, VPP is acting as the vhost driver mode and the kernel vhost is acting as the vhost device mode.

Hi. I would like to print out a field of a vnode, but the argument to the function is of type vnode_t **. If I set "this->vpp" to arg2 in an entry function to zfs_lookup(), I''d like to retrieve the value of one of the fields of *(this->vpp) in the return function. Something like the below (but the syntax below is not right): printf("zfs_lookup: %d", (*((vnode_t **)this->vpp))-&gt...

I get the above panic after nfs clients attach to this nfs server and being read/write ops on it after an unclean shutdown. I've fsck'ed the fs, and it marks it as clean, but I get this every time. It's an NFS share of a GEOM stripe (about 2TB). mode = 0100600, inum = 58456203, fs = /mnt panic: ffs_valloc: dup alloc I do have dumps from two crashes so far. This is

Anyone have problems with getaddrinfo under AIX4.3? I have built 2.5.0 under linux, HP and VPP without too much in the way of problems. However, AIX4.3 version builds OK but doesn't execute getaddrinfo correctly. Any ideas?

Hi, my FreeBSD-9/stable machine (FreeBSD freebsd-tower.goebo.site 9.1-PRERELEASE FreeBSD 9.1-PRERELEASE #2 r241044M: Sat Sep 29 12:52:01 CEST 2012 lbo@freebsd-tower.goebo.site:/usr/obj/usr/src/sys/GENERIC i386) crashes reproducibly when rsync-ing files to an NFSv4 share on the FreeBSD machine. The crash makes the system reboot. The crash creates files in /var/crash which may be obtained

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

Hello, I'm experiencing a kernel panic that appears to be caused by zfs. No errors are making it into /var/log/messages, but here is the error message that appears on my screen after panic (transcribed): panic solaris assert BSWAP_32(sa_hdr_phys->sa_magic) == SA_MAGIC, file: /src/sys/modules/zfs/../../cddl/contrib/opensolaris/uts/common/fs/zfs/sa.c, line 1262 I can reproduce this by

...ionality in question is setup- > time only. Agreed, we don't see dependency on kernel driver is a problem. mdev based vhost backend (this patch set) is independent with vhost-user extension patch set. In fact, there're a few vhost-user providers, DPDK librte_vhost is one of them. FD.IO/VPP and snabbswitch have their own vhost-user providers. So I can't agree on vhost-user extension patch depends on DPDK backend. But anyway, that's the topic of another mail thread. > > As others said, we do not need to go overeboard.

Platform: Compaq OpenVMS Alpha 7.3 Compiler: Compaq C T6.5 The following patch resolves compile problems with the HLINK.C module. The cast on function argument for the qsort() routine was wrong, and not allowing the compile to complete. When the function definiton of the hlink_compare() is corrected to have the const qualifiers, the cast inside the qsort() function call is no longer
