| | | | | When vnode bypass cannot be performed on the cdev file descriptor for read/write/poll/ioctl, call standard vnode filedescriptor fop.
* MFC r273130:kib2014-10-221-6/+9
| | | | | | Change the deadfs poll VOP to return POLLIN|POLLRDNORM if the caller is interested in i/o state. Return POLLNVAL for invalid bits, similar to poll_no_poll().

| | | | | | | | ext2fs: add ext2_getpages(). Literally copy/pasted from ffs_getpages(). Tested with: fsx
* MFC r272025:trasz2014-09-251-0/+2
| | | | | | | | | | | | Fix thinko that, with two map entries like shown below, in that order, made autofs mix them up: the second one wasn't visible in ls(1) output, and trying to access it would trigger mount for the first one. foobar host:/foobar foo host:/foo Approved by: re (gjb) Sponsored by: The FreeBSD Foundation
* MFC r270507:trasz2014-08-311-3/+0
| | | | | | | | Fix bug that, assuming a/ is a root of NFS filesystem mounted on autofs, prevented "mv a/from a/to" from working, while "cd a && mv from to" was ok. PR: 192948 Sponsored by: The FreeBSD Foundation
* MFC r270402:trasz2014-08-314-73/+77
| | | | | | | | Autofs softc needs to be global anyway, so don't pass it as a local variable, and don't store in autofs_mount. Also rename it from 'sc' to 'autofs_softc', since it's global and extern. Sponsored by: The FreeBSD Foundation
* MFC r270399:trasz2014-08-311-0/+8

* MFC r270207:trasz2014-08-311-14/+18

* MFC r270096:trasz2014-08-315-0/+1722
| | | | | | | | | | | | | Bring in the new automounter, similar to what's provided in most other UNIX systems, eg. MacOS X and Solaris. It uses Sun-compatible map format, has proper kernel support, and LDAP integration. There are still a few outstanding problems; they will be fixed shortly.

* MFC r269708:kib2014-08-221-4/+40
| | | | | Unlock ldvp and lock dvp to compensate for possible ldvp unlock in lower VOP_LOOKUP() and dvp reclamation. Use cached value of dvp->v_mount.
* MFC: r269771rmacklem2014-08-161-4/+3
| | | | | | Change the NFS server's printf related to hitting the DRC cache's flood level so that it suggests increasing vfs.nfsd.tcphighwater.
* MFC r269347:kib2014-08-072-16/+8
| | | | | Do not generate 1000 unique lock names for nfsrc hash chain locks. Shorten the names of some nfs mutexes.
* MFC r269187:kib2014-08-041-0/+4
| | | | | Assert that nullfs vnode has VV_ROOT set whenever lower vnode has. Assert that dotdot lookup on the root vnode is not performed.
* MFC: r268273rmacklem2014-08-031-2/+4
| | | | | | | | | | | | The new NFSv3 server did not generate directory postop attributes for the reply to ReaddirPlus when the server failed within the loop that calls VFS_VGET(). This failure is most likely an error return from VFS_VGET() caused by a bogus d_fileno that was truncated to 32bits. This patch fixes the server so that it will return directory postop attributes for the failure. It does not fix the underlying issue caused by d_fileno being uint32_t when a file system like ZFS generates a fileno that is greater than 32bits.
* MFC: r268115rmacklem2014-08-0118-332/+2060
| | | | | | | | Merge the NFSv4.1 server code in projects/nfsv4.1-server over into head. The code is not believed to have any effect on the semantics of non-NFSv4.1 server behaviour. It is a rather large merge, but I am hoping that there will not be any regressions for the NFS server.
* MFC r268765:kib2014-07-301-1/+0
| | | | Remove unused header.
* MFC r268764:kib2014-07-305-36/+0
| | | | | Check for the cross-device cross-link attempt in the VFS, instead of VOP_LINK() implemenations.
* MFC r268766:kib2014-07-281-1/+3
| | | | Do not ignore error from tmpfs_alloc_vp().
* MFC r268617:kib2014-07-283-27/+74
| | | | Rework the tmpfs unmount.
* MFC r268615:kib2014-07-281-1/+1
| | | | | | | | | | | Add OBJ_TMPFS_NODE flag. MFC r268616: Set the OBJ_TMPFS_NODE flag for vm_object of VREG tmpfs node. MFC r269053: Correct assertion. tmpfs vm object is always at the bottom of the shadow chain.
* MFC r268614:kib2014-07-281-13/+13
| | | | | Use tmpfs_vn_get_ino_gen() to handle the races with reclaim in tmpfs dotdot lookup.

| | | | Add some assertions for the code handling vm_object for tmpfs vnode.
* MFC r268608:kib2014-07-281-2/+2
| | | | | The tmpfs_link() must not dereference the filesystem-specific data for a vnode until it is verified that the vnode indeed belongs to tmpfs mount.
* MFC r268606:kib2014-07-282-85/+52
| | | | | | Generalize vn_get_ino() to allow filesystems to use custom vnode producer. Convert inline copies of vn_get_ino() in msdosfs and cd9660 into the uses of vn_get_ino_gen().
* MFC r268605:kib2014-07-287-132/+0

| | | | | Change NFS readdir() to only ignore cookies preceding the given offset for UFS rather than for all but ZFS.
* MFC: r268008rmacklem2014-07-131-17/+17
| | | | | | | | | | There might be a potential race condition for the NFSv4 client when a newly created file has another open done on it that update the open mode. This patch moves the code that updates the open mode up into the block where the mutex is held to ensure this cannot happen. No bug caused by this potential race has been observed, but this fix is a safety belt to ensure it cannot happen.
* MFC r265206:mjg2014-07-061-3/+1
| | | | | | | | Ignore the error from pipespace_new when creating a pipe. It can fail if pipe map is exhausted (as a result of too many pipes created), but it is not fatal and could be provoked by unprivileged users. The only consequence is worse performance with given pipe.
* MFC r267564:kib2014-06-245-34/+20
| | | | | In msdosfs_setattr(), add a check for result of the utimes(2) permissions test. Refactor the permission checks for utimes(2).
* MFC r267060:kib2014-06-111-0/+2
| | | | Allow shared locking for the tmpfs vnode.
* MFC: r267191rmacklem2014-06-101-7/+0
| | | | | | | | | The new NFS server would not allow a hard link to be created to a symlink. This restriction (which was inherited from OpenBSD) is not required by the NFS RFCs. Since this is allowed by the old NFS server, it is a POLA violation to not allow it. This patch modifies the new NFS server to allow this.
* MFC r265275:kib2014-05-101-0/+11
| | | | | Overwrite the de_Name for the directories on rename to correct the dot name.
* MFC: r265252rmacklem2014-05-082-6/+20
| | | | | | | | | | | The new draft specification for NFSv4.0 specifies that a server should either accept owner and owner_group strings that are just the digits of the uid/gid or return NFS4ERR_BADOWNER. This patch adds a sysctl vfs.nfsd.enable_stringtouid, which can be set to enable the server w.r.t. accepting numeric string. It also ensures that NFS4ERR_BADOWNER is returned if numeric uid/gid strings are not enabled. This fixes the server for recent Linux nfs4 clients that use numeric uid/gid strings by default.
* MFC: r264888rmacklem2014-05-081-0/+1
| | | | | | The PR reported that the old NFS server did not set uio_td == NULL for the VOP_READ() call. This patch fixes both the old and new server for this case.
* MFC: r264845rmacklem2014-05-071-7/+6
| | | | | | Remove an unnecessary level of indirection for an argument. This simplifies the code and should avoid the clang sparc port from generating an abort() call.
* MFC: r264842rmacklem2014-05-071-2/+5
| | | | | | Modify the NFSv4 client's Pathconf RPC (actually a Getattr Op.) so that it only does the RPC for names that are answered by the RPC. Doing the RPC for other names is harmless, but unnecessary.
* MFC: r264738rmacklem2014-05-061-1/+3
| | | | | | For an NFSv4 mount with the "nocto" option, don't get the up to date file attributes upon close. This reduces the Getattr RPC count by about 65% for software builds.
* MFC: r264705, r264749rmacklem2014-05-062-1/+17
| | | | | | | Modify the NFSv4 client create/mkdir RPC so that it acquires post-create/mkdir directory attributes. This allows the RPC to name cache the newly created directory and reduces the lookup RPC count for applications creating a lot of directories.
* MFC: r264681rmacklem2014-05-062-5/+17
| | | | | | | Modify the NFSv4 client open/create RPC so that it acquires post-open/create directory attributes. This allows the RPC to name cache the newly created file and reduces the lookup RPC count by about 10% for software builds.
* MFC: r264672rmacklem2014-05-063-29/+45
| | | | | | | Modify the Lookup RPC for NFSv4 so that it acquires directory attributes. This allows the client to cache directory names when they are looked up, reducing the Lookup RPC count by about 40% for software builds.
* MFC r264494:ae2014-05-023-18/+64
| | | | | | | | | | | | Use SMB_QUERY_FS_SIZE_INFO request to populate statfs structure. When server doesn't support this request, try to use SMB_INFO_ALLOCATION. And use SMB_COM_QUERY_INFORMATION_DISK request as fallback. MFC r264600: Remove redundant unlock. This code was removed from the opensolaris and darwin's netsmb implementations, in DfBSD it also has been disabled.
