1.22	12-Oct-2024	bad	fix spelling of rump_nqmfs and remove accidental "presents"
1.21	06-Jun-2022	nia	branches: 1.21.4; build system: Revert all the recent additions of MK[...] knobs that allow conditionally disabling the building of certain user space programs in the 'base' set. There is not enough consensus that this is the right way and a few people had strong objections, see source-changes-d@.
1.20	27-May-2022	nia	mk: Add a MKLFS flag for excluding the log-structured filesystem userspace tools from the build.
1.19	04-Apr-2020	christos	We don't have smbfs anymore.
1.18	21-May-2017	riastradh	branches: 1.18.10; Remove MKCRYPTO option. Originally, MKCRYPTO was introduced because the United States classified cryptography as a munition and restricted its export. The export controls were substantially relaxed fifteen years ago, and are essentially irrelevant for software with published source code. In the intervening time, nobody bothered to remove the option after its motivation -- the US export restriction -- was eliminated. I'm not aware of any other operating system that has a similar option; I expect it is mainly out of apathy for churn that we still have it. Today, cryptography is an essential part of modern computing -- you can't use the internet responsibly without cryptography. The position of the TNF board of directors is that TNF makes no representation that MKCRYPTO=no satisfies any country's cryptography regulations. My personal position is that the availability of cryptography is a basic human right; that any local laws restricting it to a privileged few are fundamentally immoral; and that it is wrong for developers to spend effort crippling cryptography to work around such laws. As proposed on tech-crypto, tech-security, and tech-userlevel to no objections: https://mail-index.netbsd.org/tech-crypto/2017/05/06/msg000719.html https://mail-index.netbsd.org/tech-security/2017/05/06/msg000928.html https://mail-index.netbsd.org/tech-userlevel/2017/05/06/msg010547.html P.S. Reviewing all the uses of MKCRYPTO in src revealed a lot of bad crypto that was conditional on it, e.g. DES in telnet... That should probably be removed too, but on the grounds that it is bad, not on the grounds that it is (nominally) crypto.
1.17	08-Nov-2015	christos	Some of the puffs mount programs don't need RUMP, re-enable them.
1.16	24-Jul-2011	uch	v7fs rump support
1.15	11-Jul-2010	mrg	ldap is configured to depend upon MKCRYPTO no, so force MKLAP=no if MKCRYPTO=no. don't build pkg_install, libcrypto tests or rump_smbfs if MKCRYPTO=no. mark librumpcrypto, rump_smb, pkg_* fix set lists as appropriate.
1.14	29-Apr-2010	pooka	Add rump_au-naturel, which instead of mounting a file system inside the rump kernel just attaches to / in said rump kernel instance. This is mostly useful in case wanting to see what nodes components create (see Makefile). not built without manual intervention
1.13	31-Mar-2010	pooka	Add kernfs server. Don't build & install it by default, since it represents the state of the rump virtual kernel and not the host kernel. However, it's useful for debugging kernfs.
1.12	08-Mar-2010	pooka	add commented out nqmfs
1.11	05-Dec-2009	pooka	Remove the portalfs kernel file system driver. Replace mount_portal(8) with a version based on puffs. User functionality remains the same.
1.10	06-Sep-2009	pooka	Build & install rump_smbfs
1.9	31-Jul-2009	pooka	add commented-out rump_fdesc along with an explanation
1.8	16-Oct-2008	pooka	Add & enable rump_nfs.
1.7	04-Sep-2008	pooka	forgot to commit this - descend into rump_sysvbfs
1.6	29-Jul-2008	pooka	Install rump libraries and utilities to the base system and remove the private non-installed build infrastructure from sys/rump. breakdown of commit: * install relevant headers into /usr/include/rump * build sys/rump/librump/rumpuser and sys/rump/librump/rumpkern from src/lib and install as librumpuser and librump, respectively + this retains the ability to test a librump build with just the kernel sources at hand * move sys/rump/fs/lib/libukfs and sys/rump/fs/lib/libp2k to src/lib for general consumption, they are not kernel-space dwellers anyway * build and install sys/rump/fs/lib/lib$fs as librumpfs_$fs * add chapter 3 manual pages for rump, rumpuser, ukfs and p2k * build and install userspace kernel file system daemons if MKPUFFS=yes is spexified * retire fsconsole for now, it will make a comeback with an actually implemented version shortly
1.5	09-Aug-2007	pooka	branches: 1.5.10; add sysctlfs
1.4	08-Jul-2007	pooka	build & install puffsportal (if MKPUFFS)
1.3	02-Jul-2007	pooka	Add initial puffs version of mount_portal, eventually to replace portalfs. Uses the same config files etc. as the "regular" mount_portal, and actually compiles a lot of the code directly from under src/sbin/mount_portal. Doesn't yet support concurrent access, but I have a pretty clear vision on how to neatly fix that.
1.2	21-Apr-2007	pooka	descend into mount_9p
1.1	29-Dec-2006	pooka	if MKPUFFS=yes is given, build & install mount_psshfs (default: no)
1.5.10.1	18-Sep-2008	wrstuden	Sync with wrstuden-revivesa-base-2.
1.18.10.1	08-Apr-2020	martin	Merge changes from current as of 20200406
1.21.4.2	02-Aug-2025	perseant	Sync with HEAD
1.21.4.1	29-Jun-2024	perseant	Implementation of exFAT filesystem, with compilation conditional on MKEXFATFS make variable.
1.18	07-Jul-2021	martin	Allow to set sanitizer flags for the rump build from the build.sh command line, like: -V RUMP_SANITIZE=address
1.17	17-May-2020	christos	reverse the order for sun2
1.16	16-May-2020	christos	Oops forgot to commit this.
1.15	23-Jan-2016	christos	Define _KERNTYPES for things that need it.
1.14	16-Jan-2014	christos	eliminate use of bsd.sys.mk from Makefiles
1.13	25-Jan-2010	pooka	branches: 1.13.6; 1.13.12; Define concept "disk based file system" and flag appropriate file systems as such.
1.12	05-Nov-2009	pooka	pump up the WARNS to 4
1.11	21-Jul-2009	pooka	Make rump_lfs work again: load fs components dynamically instead of trying to link them in on the command line and get pounded by link set failage.
1.10	18-Jan-2009	he	Change the use of formally undocumented features, which have now been made to fail. Specifically, change .ifdef(SYMBOL) -> .ifdef SYMBOL or .if defined(SYMBOL), and corresponding for .ifndef. Also correct one error in lib/libm/Makefile (.ifdef (${MKCOMPLEX} != "no")?!?).
1.9	08-Jan-2009	pooka	Disable static linking against kernel modules and always use shared libraries. Kernel module support will require some more happy days with the kernel linker.
1.8	05-Jan-2009	pooka	malloc(9) -> kern_malloc(9): we don't need --wrap anymore.
1.7	30-Dec-2008	pooka	Link self-contained file systems (i.e. do not depend on other file systems) against the kernel module on select archs.
1.6	19-Nov-2008	pooka	Split vfs out of rumpkern into rumpvfs. Non-fs rumps no longer include the file system code. File system rumps explicitly need to include rumpvfs from now on.
1.5	06-Aug-2008	pooka	Add manual pages for rump file system servers.
1.4	05-Aug-2008	pooka	Refactor mount utilities to provide a mount_fs_parseargs() routine. Use this routine both in mount_fs and rump_fs to provide equivalent command line parameters and therefore usage interchangeability. While doing this, combine some common mountgoop to mountprog.h
1.3	29-Jul-2008	pooka	Install rump libraries and utilities to the base system and remove the private non-installed build infrastructure from sys/rump. breakdown of commit: * install relevant headers into /usr/include/rump * build sys/rump/librump/rumpuser and sys/rump/librump/rumpkern from src/lib and install as librumpuser and librump, respectively + this retains the ability to test a librump build with just the kernel sources at hand * move sys/rump/fs/lib/libukfs and sys/rump/fs/lib/libp2k to src/lib for general consumption, they are not kernel-space dwellers anyway * build and install sys/rump/fs/lib/lib$fs as librumpfs_$fs * add chapter 3 manual pages for rump, rumpuser, ukfs and p2k * build and install userspace kernel file system daemons if MKPUFFS=yes is spexified * retire fsconsole for now, it will make a comeback with an actually implemented version shortly
1.2	28-May-2007	tls	branches: 1.2.12; Add new Makefile knob, USE_FORT, which extends USE_SSP by turning on the FORTIFY_SOURCE feature of libssp, thus checking the size of arguments to various string and memory copy and set functions (as well as a few system calls and other miscellany) where known at function entry. RedHat has evidently built all "core system packages" with this option for some time. This option should be used at the top of Makefiles (or Makefile.inc where this is used for subdirectories) but after any setting of LIB. This is only useful for userland code, and cannot be used in libc or in any code which includes the libc internals, because it overrides certain libc functions with macros. Some effort has been made to make USE_FORT=yes work correctly for a full-system build by having the bsd.sys.mk logic disable the feature where it should not be used (libc, libssp iteself, the kernel) but no attempt has been made to build the entire system with USE_FORT and doing so will doubtless expose numerous bugs and misfeatures. Adjust the system build so that all programs and libraries that are setuid, directly handle network data (including serial comm data), perform authentication, or appear likely to have (or have a history of having) data-driven bugs (e.g. file(1)) are built with USE_FORT=yes by default, with the exception of libc, which cannot use USE_FORT and thus uses only USE_SSP by default. Tested on i386 with no ill results; USE_FORT=no per-directory or in a system build will disable if desired.
1.1	29-Dec-2006	pooka	Makefile.inc to get BINDIR right
1.2.12.1	18-Sep-2008	wrstuden	Sync with wrstuden-revivesa-base-2.
1.13.12.1	20-Aug-2014	tls	Rebase to HEAD as of a few days ago.
1.13.6.1	22-May-2014	yamt	sync with head. for a reference, the tree before this commit was tagged as yamt-pagecache-tag8. this commit was splitted into small chunks to avoid a limitation of cvs. ("Protocol error: too many arguments")
1.14	04-Apr-2020	christos	We don't have smbfs anymore.
1.13	24-Jul-2011	uch	branches: 1.13.42; v7fs rump support
1.12	22-Nov-2010	pooka	include script rcsid in generated file (no change to rendered output)
1.11	22-Nov-2010	pooka	Generate different manpages for 1) disk 2) net 3) fictional file systems.
1.10	21-Nov-2010	pooka	* document disk.img%DISKLABEL:p% * tweaks
1.9	31-Mar-2010	pooka	Add note saying that the manual page is autogenerated and all parts may not apply to this particular server. TODO: have three different texts, one for device backed file systems (e.g. ffs), another for network backed (e.g. nfs), and a third for fictional (e.g. kernfs)
1.8	15-Feb-2009	pooka	* include "pseudo-device putter" in synopsis as requested by hubertf * note that rump p2k utilities are currently experimental (noted already on the rump manpages, but better note it here also)
1.7	10-Feb-2009	pooka	Note that the rump file servers do not require use of vnconfig when mounting images. Suggested by apb
1.6	11-Jan-2009	wiz	branches: 1.6.2; Mark up arguments with Ar and drop trailing whitespace.
1.5	11-Jan-2009	pooka	Note mount -o rump support.
1.4	16-Oct-2008	pooka	branches: 1.4.2; Be more verbose about the performance hit.

1.6.2.1	13-May-2009	jym	Sync with HEAD. Third (and last) commit. See http://mail-index.netbsd.org/source-changes/2009/05/13/msg221222.html
1.13.42.1	08-Apr-2020	martin	Merge changes from current as of 20200406
1.6	30-Aug-2020	christos	include bsd.init.mk to avoid: make: Bad conditional expression ` != "no"' in != "no"? -DINET6 :
1.5	19-Jun-2020	uwe	Use ?:: modifier instead of .if to check for ipv6. This way we don't have to include bsd.init.mk early.
1.4	13-Jun-2020	uwe	Support IPv6. Use getaddrinfo(3). Add -4 and -6 command line options. Obey USE_INET6.
1.3	22-Apr-2009	lukem	Enable WARNS=4 by default, except for: cpuctl dumplfs hprop ipf iprop-log kadmin kcm kdc kdigest kimpersonate kstash ktutil makefs ndbootd ntp pppd quot racoon racoonctl rtadvd sntp sup tcpdchk tcpdmatch tcpdump traceroute traceroute6 user veriexecgen wsmoused zic (Mostly third-party applications)
1.2	18-Jul-2007	pooka	branches: 1.2.16; 1.2.20; get rid of DBG=
1.1	21-Apr-2007	pooka	mount_9p: mount a file server using the Plan9 file sharing protocol Works, but lots of little things to nibble on: * fix permissions to work better * limit the amount of open files required * do constant folding with psshfs code * support authentication etcetc.
1.2.20.1	13-May-2009	jym	Sync with HEAD. Third (and last) commit. See http://mail-index.netbsd.org/source-changes/2009/05/13/msg221222.html
1.2.16.2	18-Jul-2007	pooka	get rid of DBG=
1.2.16.1	18-Jul-2007	pooka	file Makefile was added on branch matt-mips64 on 2007-07-18 22:39:00 +0000
1.11	28-May-2020	uwe	Do not send dummy Tauth, it's completely unnecessary. The best way to not use authentication is to not use authentication. Cf. http://man.cat-v.org/plan_9/5/attach
1.10	17-May-2019	ozaki-r	mount_9p: add initial support for 9P2000.u The implementation enables to work with a server talking 9P2000.u. However, it doesn't use the extended fields yet; it just ignores those of received messages and sets "please ignore" values to those of sending messages such as zero-length strings and maximum unsigned values. The feature is enabled by the -u option.
1.9	22-Jun-2011	mrg	branches: 1.9.42; remove some always true if () checks GCC 4.5.3 picks up.
1.8	24-Aug-2008	pooka	fix tyop in error message, no functional change
1.7	30-Nov-2007	pooka	branches: 1.7.8; Rototill. Ok, ok, a few more words about it: stop holding puffs_cc as a holy value and passing it around to almost every possible place (popquiz: which kernel variable does this remind you of?). Instead, pass the natural choice, puffs_usermount, and fetch puffs_cc via puffs_cc_getcc() only in routines which actually need it. This not only simplifies code, but (thanks to the introduction of puffs_cc_getcc()) enables constructs which weren't previously sanely possible, say layering as a curious example. There's still a little to do on this front, but this was the major fs interface blast.
1.6	27-Nov-2007	pooka	Remove "puffs_cid" from the puffs interface following l-removal from the kernel vfs interfaces. puffs_cc_getcaller(pcc) can be used now should the same information be desired.
1.5	17-Jul-2007	pooka	branches: 1.5.4; support standard user@host:path mount argument
1.4	01-Jul-2007	pooka	adapt: pid -> const struct puffs_cid *
1.3	11-May-2007	pooka	Error with rtagid instead of tagid. caught by Dan's compiler flags.
1.2	05-May-2007	pooka	Adapt to use puffs_framebuf. This gets rid of most of the duplicated code between mount_psshfs and mount_9p and clarifies the code structure.
1.1	21-Apr-2007	pooka	mount_9p: mount a file server using the Plan9 file sharing protocol Works, but lots of little things to nibble on: * fix permissions to work better * limit the amount of open files required * do constant folding with psshfs code * support authentication etcetc.

1.17	11-Feb-2022	uwe	mount_9p(8): Use full month name in previos (oops).
1.16	10-Feb-2022	uwe	mount_9p(8): document the new -C option.
1.15	14-Jun-2020	uwe	Support optional square brackets around the host name. The brackets are required when using numeric IPv6 addresses as they contain colons as part of their syntax. We do not enforce that the thing in the brackets is a numeric IPv6 address - this matches scp syntax and behavior.
1.14	13-Jun-2020	uwe	Support IPv6. Use getaddrinfo(3). Add -4 and -6 command line options. Obey USE_INET6.
1.13	30-May-2020	uwe	Provide list of options for ease of reference.
1.12	28-Oct-2019	wiz	Sort SEE ALSO. "file system" police.

1.6	20-May-2007	pooka	branches: 1.6.4; Change the signature of puffs_respcmp to return -1,0,1 for smaller, equal, larger, respectively instead of 0/1 for non/equal. This will allow sorting the buffers for faster matching in libpuffs. While here, change the name from respcmp to framecmp, as that better reflects the purpose. NOTE! there is no obvious way to make compilation fail for file systems which may already be using this feature (although I don't think there are any outside our tree, as the feature is two weeks old). Nevertheless, non-updated file systems will fail very quickly.
1.5	15-May-2007	pooka	don't leak memory if getting data from the buffer fails CID 4485

1.6	11-May-2007	pooka	adapt to puffs_framebuf changes
1.5	06-May-2007	pooka	If mode is set, the uppermost byte specifying the type must be correctly, otherwise the file server will attempt a conversion. Specifically, if the directory bit is not set when changing the permissions for a directory, a conversion from directory to regular file would be attempted and naturally it being unsupported the whole chmod would fail. So supply the file type as part of the file mode.

1.35	10-Mar-2025	riastradh	mount_9p(8): Implement pathconf stub. Doesn't actually do anything useful -- it just returns EINVAL as pathconf is supposed to for unknown pathconf key names; by default, it will return ENOTSUPP, which leads applications like ls(1) to print: ls: /mnt/.git: Operation not supported This is a little silly; perhaps puffs should use EINVAL itself instead of ENOTSUPP. But this change is less risky for now. PR bin/58768: mount_9p: missing pathconf(2) support

1.33	14-Jun-2020	uwe	Support optional square brackets around the host name. The brackets are required when using numeric IPv6 addresses as they contain colons as part of their syntax. We do not enforce that the thing in the brackets is a numeric IPv6 address - this matches scp syntax and behavior.

1.30	02-Mar-2022	ozaki-r	mount_9p: fix writing to a file opened with write-only mode With the page cache, writing data to a file may demand to read contents from a storage to fill a page in the page cache first. Opening a file with write-only mode by a user lets a mount_9p process open a file with write-only mode too at a 9p server. Thus, a read request to the file from the page cache fails. So we need to open a file always with read mode (internally) even if it is opened with write-only mode by a user.

The bug's medallion begins to glow! The bug looks much better! I crumble to dust. There's probably another similar bug related to "lazy open".

Ok, ok, a few more words about it: stop holding puffs_cc as a holy value and passing it around to almost every possible place (popquiz: which kernel variable does this remind you of?). Instead, pass the natural choice, puffs_usermount, and fetch puffs_cc via puffs_cc_getcc() only in routines which actually need it. This not only simplifies code, but (thanks to the introduction of puffs_cc_getcc()) enables constructs which weren't previously sanely possible, say layering as a curious example. There's still a little to do on this front, but this was the major fs interface blast.
1.14	27-Nov-2007	pooka	Remove "puffs_cid" from the puffs interface following l-removal from the kernel vfs interfaces. puffs_cc_getcaller(pcc) can be used now should the same information be desired.
1.13	01-Jul-2007	pooka	branches: 1.13.4; adapt: **newnode etc. pointers -> struct puffs_newinfo
1.12	01-Jul-2007	pooka	adapt: pid -> const struct puffs_cid *
1.11	06-Jun-2007	pooka	Move puffs to a two clause license where it already isn't so. And as agc pointed out, even files with the third clause were already effectively two clause because of a slight bug in the language...
1.10	18-May-2007	pooka	* use NOREF setback to prompt immediate (well, once the kernel reference count goes to 0) reclaim of deleted nodes as opposed to waiting for the system to start reclaiming the freelist * combine some nodeflags from different variable to one status variable
1.9	17-May-2007	pooka	reflect changes in fs mount: use puffs_mount() instead of puffs_domount() & puffs_start()
1.8	05-May-2007	pooka	Adapt to use puffs_framebuf. This gets rid of most of the duplicated code between mount_psshfs and mount_9p and clarifies the code structure.
1.7	18-Apr-2007	pooka	psbuf_recycle now exists, so use it instead of destroy&make in one spot I probably missed originally. No real functional change.
1.6	12-Apr-2007	pooka	Actually, we can't reclaim our memory image for nodes which have been nodetofh translated even if they are not valid on the sftp server anymore, because some nfs client might still be clinging on to the file handle we are reclaiming now.
1.5	12-Apr-2007	pooka	Support nfs exporting. Now, when I say support, I mean "support", due to the limitations of the backend. File handles are valid only for one session, since nodes can only be identified by pathnames and pathnames don't (all) fit into the nfs file handle space. Additionally, we can't detect if a pathname is completely replaced by another file (if it's done via some other route that through our mount, of course). But then again, that's an inherent problem with sshfs even without nfs.
1.4	12-Apr-2007	pooka	Hide struct puffs_usermount from the rest of the world and provide accessors for interesting data in it. Namely, you can now get pu->pu_privdata with puffs_getspecific(), pu->pu_pn_root with puffs_set/getroot() and pu->pu_maxreqlen with puffs_getmaxreqlen().
1.3	15-Jan-2007	pooka	* adapt to libpuffs path changes * fix bug in rename
1.2	06-Jan-2007	pooka	* do mount as a forward operation instead of a callback * process -o args for mount

1.24	03-Feb-2010	pooka	Give credit: psshfs was inspired by FUSE sshfs.
1.23	07-Jan-2010	wiz	Don't be terse.
1.22	07-Jan-2010	pooka	Add -u and -g, which allow to remap one (local,remote) uidgid, i.e. umapfs without the fuss.
1.21	20-May-2009	pooka	Copyright year management. no functional change (unless sarah disagrees)
1.20	20-May-2009	pooka	Introduce -c [12], which can be used to open 1 or 2 ssh connections to the server. If "2" is specified, a separate connection is used for data and directory operations. Using two connections can significantly increase directory operation performance on a saturated link, at least up to 30x faster.
1.19	26-Feb-2009	wiz	Make "sftp" a link.
1.18	25-Feb-2009	pooka	add caveat about info displayed by df(1)
1.17	06-Sep-2008	pooka	branches: 1.17.6; Due to a recent encounter with a sucky internet connection, add experimental option -p, which tries to reestablish the connection to the sftp server in case it is lost. This currently has a few limitations (found in the man page), but generally works in some use cases. Better support might eventually emerge, but since that requires a plunge into the depths of puffs_framebuf, I need quite a bit of Fernet Branca to build up my courage before attempting it.
1.16	14-Dec-2007	jmmv	branches: 1.16.6; Add a -F option to allow passing a configuration file to ssh(1), instead of having to use multiple -O options on the command line. OKed by pooka@.
1.15	03-Dec-2007	wiz	Do not overload Xr macro.
1.14	02-Dec-2007	wiz	Sort SEE ALSO. Minor nit fixes.
1.13	08-Nov-2007	pooka	Make it possible to force attribute/directory cache re-read by sending SIGHUP to mount_psshfs.
1.12	08-Nov-2007	pooka	Make attribute & directory content caching timeout a command line option. Use -t -1 to never expire, which is nifty on a high-latency link where you know the server won't be modified from under you.
1.11	20-Oct-2007	pooka	Add option -r to specify maximum number of active read requests for each node. Setting this to a small number can be used to improve interactive performance on low-bandwidth links when performing bulk data reads. Of course I could also open separate pipes for bulk and other, but this was quicker and less intrusive and doesn't require authenticating twice.
1.10	24-Jun-2007	pooka	branches: 1.10.4; PUFFS_KFLAG_NOCACHE became two, so introduce the command line options -o nonamecache and -o nopagecache and adapt file systems where necessary.
1.9	09-May-2007	pooka	remove caveat no longer applicable
1.8	09-May-2007	tnn	Add an EXAMPLES section.
1.7	09-May-2007	tnn	Change [-O sshopt value] to [-O sshopt=value] to better conform with the way other userland apps behave. In /etc/fstab one would specify options with -O=sshopt=value.
1.6	09-May-2007	tnn	Add flag [-O sshopt value] to mount_psshfs(8), allowing the user to specify options to pass along to ssh(1). Remove redundant flag [-p sshport]; an equivalent of -O Port sshport. ok'd by pooka@
1.5	29-Apr-2007	pooka	Add -p to specify server port if someone should for some reason happen to run sshd on port, to pick a random number, 443. Probably should give a way to specify rest of the ssh options.
1.4	12-Apr-2007	pooka	document -e for nfs exportability
1.3	17-Feb-2007	pooka	* document -s * explicitly mention that this implements sshfs functionality

1.65	07-Oct-2016	christos	PR/514612: Mateusz Paszwa: When no more data, bail out (reading from empty files) instead of stuck looping.
1.64	20-Jan-2012	jakllsch	branches: 1.64.22; Ensure psshfs_node_read() completely reads all data before return. Fixes file corruption in psshfs exposed with kernel MAXPHYS at 128KiB.
1.63	12-Aug-2011	riastradh	branches: 1.63.2; Cache vattr in psshfs's setattr. This means within the cache window, a setattr that wouldn't change the remote file's attributes from our current view of them will not be relayed to the server and wait for the server to answer. Thus, e.g., a process with a periodic timer interrupt that calls open(2) in a loop can make progress with much higher probability than without caching. XXX The test case doesn't work, so it's currently disabled. It needs to stop the child of sshd that is handling an sftp session, not sshd itself, and it's not obvious how to do that. ok pooka
1.62	29-Oct-2010	pooka	Make error message more userfriendly in cases where server does not support sftp.
1.61	01-Apr-2010	pooka	In case we create a file, reclaim the vnode, and lookup the file without the directory timeout expiring, we get vattr_null as the attributes for that file. Ensure that we always report sane attributes by getting them from the server if this is the case. (also, sprinkle some const) Fixes problem reported by dyoung. But wait! The bug's medallion begins to glow! The bug looks much better! I crumble to dust. There's probably another similar bug related to "lazy open". It will trigger if we reclaim a node before the response to the open arrives. Even the comments (typoless) know about this bug ... But verifying it exists and fixing it will have to wait for another day.
1.60	07-Jan-2010	pooka	Add -u and -g, which allow to remap one (local,remote) uidgid, i.e. umapfs without the fuss.
1.59	05-Nov-2009	pooka	more lp64 it's-a-sign! fixes

1.57	20-May-2009	pooka	Introduce -c [12], which can be used to open 1 or 2 ssh connections to the server. If "2" is specified, a separate connection is used for data and directory operations. Using two connections can significantly increase directory operation performance on a saturated link, at least up to 30x faster.
1.56	29-Mar-2009	pooka	Save errno before descending to cleanup gehennom.
1.55	01-Jan-2009	pooka	branches: 1.55.2; Track parent directory in cross-directory renames so that mv & rm for the same file during a vnode's lifecycle works. ... rename fix .. it's going to be a good year ...
1.54	12-Aug-2008	pooka	branches: 1.54.4; void * -> puffs_cookie_t no functional change
1.53	09-Dec-2007	pooka	branches: 1.53.8; When creating a node, do the server-dance before creating the local data structure. This avoids a race between create and lookup, as the kernel now unlock the directory before the create operation returns.
1.52	07-Dec-2007	pooka	Don't use puffs_cc_getusermount()
1.51	07-Dec-2007	pooka	Get rid of a lot of extra complexity due to doing separate getattr requests in readdir - just use the results from the readdir rpc.
1.50	07-Dec-2007	pooka	In case a node is created in lookup in the readdir path, initialize attribute cache timestamp to be equal to that of the directory cache timestamp.
1.49	04-Dec-2007	pooka	When scheduling waiters for re-run, remove them from the waitqueue already when scheduling to make sure they're not scheduled more than once.
1.48	30-Nov-2007	pooka	Rototill. Ok, ok, a few more words about it: stop holding puffs_cc as a holy value and passing it around to almost every possible place (popquiz: which kernel variable does this remind you of?). Instead, pass the natural choice, puffs_usermount, and fetch puffs_cc via puffs_cc_getcc() only in routines which actually need it. This not only simplifies code, but (thanks to the introduction of puffs_cc_getcc()) enables constructs which weren't previously sanely possible, say layering as a curious example. There's still a little to do on this front, but this was the major fs interface blast.
1.47	30-Nov-2007	pooka	Introduce the concept of lazyopens. This means that when a file handle open is requested, it is waited for only if the node was not previously succesfully opened. The actual wait for the file handle happens only when the file handle is actually needed (read or write). This in turn has the effect that reading cached files will be quick instead of waiting for the file handle from the sftp server first. The wait previously could be very long if there were serveral hundred k of outstanding requests in a limited-bandwidth link. The code is in some need of serious handholding, but it works, so I'll leave that as "future work".
1.46	27-Nov-2007	pooka	Remove "puffs_cid" from the puffs interface following l-removal from the kernel vfs interfaces. puffs_cc_getcaller(pcc) can be used now should the same information be desired.
1.45	18-Nov-2007	pooka	Don't bother tracking opencount and try to close file handles in the close method - simply just wait for inactive and do it there.
1.44	11-Nov-2007	pooka	Don't overload "attributes last read" for the symlink cache, use a separate variable.
1.43	10-Nov-2007	pooka	Cache readlink results similarly to attributes. Makes "cd" fast for a slow connection if a symlink is along the path. (this should be done elsewhere, but I want it for sshfs now)
1.42	21-Oct-2007	pooka	Use puffs_cc_schedule() (which is an exported interface) instead of plugging directly to puffs_goto().
1.41	20-Oct-2007	pooka	Add option -r to specify maximum number of active read requests for each node. Setting this to a small number can be used to improve interactive performance on low-bandwidth links when performing bulk data reads. Of course I could also open separate pipes for bulk and other, but this was quicker and less intrusive and doesn't require authenticating twice.
1.40	16-Oct-2007	pooka	Close file handles if opencount drops to zero instead of closing them if it does not drop to zero, i.e. fix a pretty obvious bug.
1.39	24-Aug-2007	pooka	branches: 1.39.2; If a node is forcibly reclaimed, close can be called more times than open (or less, for the particular fs). So don't be uptight about opencount.
1.38	23-Aug-2007	pooka	Prevent crash in case there is more than one reader for the same directory concurrently. Might need to revisit the method used here later, though.
1.37	29-Jul-2007	pooka	branches: 1.37.4; make closehandles() void, because that's what it is
1.36	27-Jul-2007	pooka	Track memory mappings. Close file handles already in close() if there are no active mappings, otherwise do the standard inactive() run.
1.35	19-Jul-2007	pooka	Oops, the cookies for nfs of course represent the next directory entry offset, not the current one.
1.34	16-Jul-2007	pooka	If the target node exists in rename, do not try to issue a setback to signal no references, as that is not currently supported for node_rename(). The removed node will not immediately be reclaimed, but we can live with that for now. While here, factor the removal code a bit to share with remove and rmdir. fixes PR kern/36637 by reinoud
1.33	02-Jul-2007	pooka	adapt: inactive no longer comes with int *refcount (not that it was used except for setting the default here anyway)
1.32	01-Jul-2007	pooka	adapt: **newnode etc. pointers -> struct puffs_newinfo

1.30	06-Jun-2007	pooka	Move puffs to a two clause license where it already isn't so. And as agc pointed out, even files with the third clause were already effectively two clause because of a slight bug in the language...
1.29	18-May-2007	pooka	remove obvious incorrect assert() from doreclaim() and remove the whole PSN_NUKED bit - it's not very useful because of the noref setback.
1.28	18-May-2007	pooka	* use NOREF setback to prompt immediate (well, once the kernel reference count goes to 0) reclaim of deleted nodes as opposed to waiting for the system to start reclaiming the freelist * combine some nodeflags from different variable to one status variable

1.26	11-May-2007	pooka	adapt to puffs_framebuf changes
1.25	07-May-2007	pooka	Use inactive-on-demand, set inactive request in open() to close file handles when last reference is removed from the kernel.
1.24	06-May-2007	pooka	Open files in open and close them in inactive. This avoids the silly and problematic chmod + open + "un"chmod in write, among other things.
1.23	06-May-2007	pooka	Fire off FXP_CLOSE in create() and return immediately instead of waiting for the result.
1.22	05-May-2007	pooka	Adapt to use puffs_framebuf. This gets rid of most of the duplicated code between mount_psshfs and mount_9p and clarifies the code structure.
1.21	01-May-2007	pooka	g/c forgotten printf
1.20	19-Apr-2007	pooka	use puffs_cc_getspecific() where puffs_usermount is not required
1.19	17-Apr-2007	pooka	use PUFFS_STORE_DCOOKIE
1.18	12-Apr-2007	pooka	Actually, we can't reclaim our memory image for nodes which have been nodetofh translated even if they are not valid on the sftp server anymore, because some nfs client might still be clinging on to the file handle we are reclaiming now.
1.17	12-Apr-2007	pooka	Support nfs exporting. Now, when I say support, I mean "support", due to the limitations of the backend.

But then again, that's an inherent problem with sshfs even without nfs.
1.16	12-Apr-2007	pooka	Hide struct puffs_usermount from the rest of the world and provide accessors for interesting data in it. Namely, you can now get pu->pu_privdata with puffs_getspecific(), pu->pu_pn_root with puffs_set/getroot() and pu->pu_maxreqlen with puffs_getmaxreqlen().
1.15	11-Apr-2007	pooka	adapt to new readdir signature. no functional change
1.14	09-Apr-2007	pooka	fix another case of checking for return value from wrong variable (that's what you get when you copypaste code, a cid with a pin to burst your bubble, that's what you get for all your troubles, I'll never copypaste again) CID 4461
1.13	09-Apr-2007	pooka	Check for success from correct variable after allocnode() CID 4460
1.12	22-Mar-2007	pooka	If we have to do a stat in lookup, update time of last stat for the new node to avoid a most likely immediate stat from the server.
1.11	22-Mar-2007	pooka	In case lookup from the directory listing fails, try statting the target before giving up. Makes it possible to access files from -r+x directories.
1.10	13-Mar-2007	pooka	* don't require a directory entry to exist for a reclaimee node. this can happen legally when a file is removed from backing storage not using this sshfs instance, a readdir is executed for the parent directory and only then the node gets reclaimed. * now that there is a mechanism in place which does not require a pcc to do an sftp transaction, do not yield() in operations where the final transaction is something where we don't care about the return value (e.g. close handle). speedup benefit for no cost.
1.9	27-Feb-2007	pooka	size_t -> uint32_t cleanup to make LP64 build noticed by wiz
1.8	15-Feb-2007	pooka	Support reclaim. To support dotdot lookup, here we leave the reclaimed nodes hanging until all their children have been reclaimed and then reclaim everything we can as far up to root as possible. This is because the file system structures are currently interlinked in a fashion which would make dotdot lookup based on purely a path instead of a in-memory node parent member pointer very difficult. Yes, this deserves a closer look some day.
1.7	10-Feb-2007	pooka	Don't destroy puffs_nodes in success paths of remove and rmdir: the kernel assumes that they will not be recycled until reclaim.
1.6	09-Feb-2007	pooka	Implement "superreaddir". This issues a getattr for all the directory entries already in readdir and caches the results instead of waiting for each individial getattr from the kernel. For high-latency links the difference in "ls -l" is quite astounding and even on my lan "ls -lR" is faster than for nfs in a normal directory hierarchy (i.e. not one artifically setup to have thousands of files per directory). TODO: implement some sort of bandwidth/latency measurement in the code and enable or disable this option based on than information (and a command-line flag).
1.5	15-Jan-2007	pooka	* adapt to libpuffs path changes * fix bug in rename
1.4	11-Jan-2007	pooka	Give nukenode a destroy flag. If given, it completely wipes out the node and directory cache (for directories). Otherwise it just nukes directory entry information. The latter case is used when renaming.
1.3	07-Jan-2007	pooka	* Adapt to openssh standard of timestamps in file attributes. Maybe should make this work with the IETF standard some day, also. * kludge with writes and permissions a bit to be able to flush data cached in ubc to files which are already with r/o permissions in the backend

1.9	20-May-2007	pooka	Change the signature of puffs_respcmp to return -1,0,1 for smaller, equal, larger, respectively instead of 0/1 for non/equal. This will allow sorting the buffers for faster matching in libpuffs. While here, change the name from respcmp to framecmp, as that better reflects the purpose. NOTE! there is no obvious way to make compilation fail for file systems which may already be using this feature (although I don't think there are any outside our tree, as the feature is two weeks old).

1.2	07-Jan-2007	pooka	* Adapt to openssh standard of timestamps in file attributes. Maybe should make this work with the IETF standard some day, also. * kludge with writes and permissions a bit to be able to flush data cached in ubc to files which are already with r/o permissions in the backend

1.63	19-May-2011	riastradh	Initialize psshfs root node's readdir waiters queue. Every other node's readder waiters queue is initialized in makenode, but the root node is created specially. ok pooka

1.58	07-Jan-2010	pooka	errx() already contains progname ...
1.57	07-Jan-2010	pooka	Don't allow mangling of uid or gid -1, since they have a special meaning in the sftp protocol.
1.56	07-Jan-2010	pooka	Add -u and -g, which allow to remap one (local,remote) uidgid, i.e. umapfs without the fuss.
1.55	05-Nov-2009	pooka	const woes
1.54	20-May-2009	pooka	wait() for dead ssh processes (but don't block, so we might have one teeny zmobie in the system).
1.53	20-May-2009	pooka	Fix SNAFU in previous: connection handshake is already handled by the connect routine now, so we're not required/allowed to do it twice. Makes reconnect on dead link work again.
1.52	20-May-2009	pooka	Copyright year management. no functional change (unless sarah disagrees)
1.51	20-May-2009	pooka	Introduce -c [12], which can be used to open 1 or 2 ssh connections to the server. If "2" is specified, a separate connection is used for data and directory operations. Using two connections can significantly increase directory operation performance on a saturated link, at least up to 30x faster.
1.50	23-Feb-2009	pooka	Support statvfs@openssh.com extension where available. Makes df(1) return something other than just 0. caveat: statvfs is done for the mountpoint path, so might not give the truth about a directory inside the mountpoint.
1.49	06-Sep-2008	pooka	branches: 1.49.6; Due to a recent encounter with a sucky internet connection, add experimental option -p, which tries to reestablish the connection to the sftp server in case it is lost. This currently has a few limitations (found in the man page), but generally works in some use cases. Better support might eventually emerge, but since that requires a plunge into the depths of puffs_framebuf, I need quite a bit of Fernet Branca to build up my courage before attempting it.
1.48	11-Aug-2008	pooka	call puffs_exit()
1.47	14-Dec-2007	jmmv	branches: 1.47.6; Add a -F option to allow passing a configuration file to ssh(1), instead of having to use multiple -O options on the command line. OKed by pooka@.
1.46	30-Nov-2007	pooka	Introduce the concept of lazyopens. This means that when a file handle open is requested, it is waited for only if the node was not previously succesfully opened. The actual wait for the file handle happens only when the file handle is actually needed (read or write). This in turn has the effect that reading cached files will be quick instead of waiting for the file handle from the sftp server first. The wait previously could be very long if there were serveral hundred k of outstanding requests in a limited-bandwidth link. The code is in some need of serious handholding, but it works, so I'll leave that as "future work".
1.45	18-Nov-2007	pooka	Don't bother tracking opencount and try to close file handles in the close method - simply just wait for inactive and do it there.
1.44	16-Nov-2007	pooka	use puffs_daemon() instead of daemon()
1.43	11-Nov-2007	pooka	Don't overload "attributes last read" for the symlink cache, use a separate variable.
1.42	08-Nov-2007	pooka	Make it possible to force attribute/directory cache re-read by sending SIGHUP to mount_psshfs.
1.41	08-Nov-2007	pooka	don't allow negative timeouts apart from -1
1.40	08-Nov-2007	pooka	Make attribute & directory content caching timeout a command line option. Use -t -1 to never expire, which is nifty on a high-latency link where you know the server won't be modified from under you.
1.39	06-Nov-2007	pooka	Open the kernel descriptor as part of mount(), not init(). Then it doesn't matter if someone fork()s or does other tricks between init() and mount() (and besides, now it's where it logically should be).
1.38	05-Nov-2007	pooka	Actually, daemonize the file servers before mounting. I might require at some point that the local protocol handler does not change after the file system has been mounted.
1.37	05-Nov-2007	pooka	Pull the daemonizing code out of the library mainloop into the file servers. Calling daemon() (i.e. fork()ing) inside a library can cause nice surprises for e.g. threaded programs. As discussed with Greg Oster & others.
1.36	20-Oct-2007	pooka	Add option -r to specify maximum number of active read requests for each node. Setting this to a small number can be used to improve interactive performance on low-bandwidth links when performing bulk data reads. Of course I could also open separate pipes for bulk and other, but this was quicker and less intrusive and doesn't require authenticating twice.
1.35	01-Sep-2007	pooka	Adapt to new puffs_framev_init() signature - gotfb.
1.34	27-Jul-2007	pooka	branches: 1.34.4; 1.34.6; Track memory mappings. Close file handles already in close() if there are no active mappings, otherwise do the standard inactive() run.
1.33	17-Jul-2007	pooka	* add mntfromname parameter to puffs_init() * set it in file servers
1.32	07-Jul-2007	pooka	I'm fairly certain this file system's type is psshfs, not ppshfs (how did that manage to be there this long?)
1.31	07-Jul-2007	pooka	adapt to puffs_framebuf changes
1.30	26-Jun-2007	pooka	g/c bit about MNT_NOATIME being mandatory. it obvious isn't since the code was #if 0'd out.
1.29	06-Jun-2007	pooka	Move puffs to a two clause license where it already isn't so. And as agc pointed out, even files with the third clause were already effectively two clause because of a slight bug in the language...
1.28	21-May-2007	pooka	devnullify ssh process's stderr to avoid tty spam
1.27	17-May-2007	pooka	reflect changes in fs mount: use puffs_mount() instead of puffs_domount() & puffs_start()
1.26	15-May-2007	pooka	adapt to "step 3" of puffs_framebuf changes
1.25	11-May-2007	pooka	use puffs_mainloop(); puffs_framebuf_eventloop() is a goner
1.24	11-May-2007	pooka	adapt to puffs_framebuf changes
1.23	09-May-2007	pooka	use fprintf instead of errx for usage()
1.22	09-May-2007	tnn	Change [-O sshopt value] to [-O sshopt=value] to better conform with the way other userland apps behave. In /etc/fstab one would specify options with -O=sshopt=value.
1.21	09-May-2007	tnn	Add flag [-O sshopt value] to mount_psshfs(8), allowing the user to specify options to pass along to ssh(1). Remove redundant flag [-p sshport]; an equivalent of -O Port sshport. ok'd by pooka@
1.20	07-May-2007	pooka	Use inactive-on-demand, set inactive request in open() to close file handles when last reference is removed from the kernel.
1.19	06-May-2007	pooka	Open files in open and close them in inactive. This avoids the silly and problematic chmod + open + "un"chmod in write, among other things.
1.18	06-May-2007	pooka	adapt to puffs_framebuf_eventloop signature change
1.17	05-May-2007	pooka	Adapt to use puffs_framebuf. This gets rid of most of the duplicated code between mount_psshfs and mount_9p and clarifies the code structure.
1.16	02-May-2007	pooka	For consistency destroy kernel request putbuffers also when escaping event loop (the process is going to exit anyway, but ...)
1.15	29-Apr-2007	pooka	Add -p to specify server port if someone should for some reason happen to run sshd on port, to pick a random number, 443. Probably should give a way to specify rest of the ssh options.
1.14	22-Apr-2007	pooka	Use PUFFS_KFLAG_WTCACHE to avoid the need to do a sync(8) on the client host to get all the data onto the server.
1.13	16-Apr-2007	pooka	adapt to kernel changes with file handles
1.12	13-Apr-2007	pooka	Instead of keeping on adding parameters to puffs_mount(), make it only take the bare essentials, which currently means removing "maxreqlen" from the argument list (all current callers I'm aware of set it as 0 anyway). Introduce puffs_init(), which provides a context for setting various parameters and puffs_domount(), which can be used to mount the file system. Keep puffs_mount() as a shortcut for the above two for simple file systems. Bump development ABI version to 13. After all, it's Friday the 13th. Watch out! Bad things can happen on Friday the 13th. --No carrier--
1.11	12-Apr-2007	pooka	Support nfs exporting. Now, when I say support, I mean "support", due to the limitations of the backend. File handles are valid only for one session, since nodes can only be identified by pathnames and pathnames don't (all) fit into the nfs file handle space. Additionally, we can't detect if a pathname is completely replaced by another file (if it's done via some other route that through our mount, of course). But then again, that's an inherent problem with sshfs even without nfs.
1.10	12-Apr-2007	pooka	Hide struct puffs_usermount from the rest of the world and provide accessors for interesting data in it. Namely, you can now get pu->pu_privdata with puffs_getspecific(), pu->pu_pn_root with puffs_set/getroot() and pu->pu_maxreqlen with puffs_getmaxreqlen().
1.9	13-Mar-2007	pooka	* don't require a directory entry to exist for a reclaimee node. this can happen legally when a file is removed from backing storage not using this sshfs instance, a readdir is executed for the parent directory and only then the node gets reclaimed. * now that there is a mechanism in place which does not require a pcc to do an sftp transaction, do not yield() in operations where the final transaction is something where we don't care about the return value (e.g. close handle). speedup benefit for no cost.
1.8	15-Feb-2007	pooka	Support reclaim. To support dotdot lookup, here we leave the reclaimed nodes hanging until all their children have been reclaimed and then reclaim everything we can as far up to root as possible. This is because the file system structures are currently interlinked in a fashion which would make dotdot lookup based on purely a path instead of a in-memory node parent member pointer very difficult. Yes, this deserves a closer look some day.
1.7	09-Feb-2007	pooka	Implement "superreaddir". This issues a getattr for all the directory entries already in readdir and caches the results instead of waiting for each individial getattr from the kernel. For high-latency links the difference in "ls -l" is quite astounding and even on my lan "ls -lR" is faster than for nfs in a normal directory hierarchy (i.e. not one artifically setup to have thousands of files per directory). TODO: implement some sort of bandwidth/latency measurement in the code and enable or disable this option based on than information (and a command-line flag).

1.40	01-Apr-2010	pooka	In case we create a file, reclaim the vnode, and lookup the file without the directory timeout expiring, we get vattr_null as the attributes for that file. Ensure that we always report sane attributes by getting them from the server if this is the case. (also, sprinkle some const) Fixes problem reported by dyoung. But wait! The bug's medallion begins to glow! The bug looks much better! I crumble to dust. There's probably another similar bug related to "lazy open". It will trigger if we reclaim a node before the response to the open arrives. Even the comments (typoless) know about this bug ... But verifying it exists and fixing it will have to wait for another day.
1.39	07-Jan-2010	pooka	Add -u and -g, which allow to remap one (local,remote) uidgid, i.e. umapfs without the fuss.

1.33	07-Dec-2007	pooka	branches: 1.33.8; Don't use puffs_cc_getusermount()
1.32	07-Dec-2007	pooka	Get rid of a lot of extra complexity due to doing separate getattr requests in readdir - just use the results from the readdir rpc.
1.31	30-Nov-2007	pooka	Rototill. Ok, ok, a few more words about it: stop holding puffs_cc as a holy value and passing it around to almost every possible place (popquiz: which kernel variable does this remind you of?). Instead, pass the natural choice, puffs_usermount, and fetch puffs_cc via puffs_cc_getcc() only in routines which actually need it. This not only simplifies code, but (thanks to the introduction of puffs_cc_getcc()) enables constructs which weren't previously sanely possible, say layering as a curious example. There's still a little to do on this front, but this was the major fs interface blast.
1.30	30-Nov-2007	pooka	Introduce the concept of lazyopens. This means that when a file handle open is requested, it is waited for only if the node was not previously succesfully opened. The actual wait for the file handle happens only when the file handle is actually needed (read or write).

1.27	10-Nov-2007	pooka	Cache readlink results similarly to attributes. Makes "cd" fast for a slow connection if a symlink is along the path. (this should be done elsewhere, but I want it for sshfs now)
1.26	08-Nov-2007	pooka	Make attribute & directory content caching timeout a command line option. Use -t -1 to never expire, which is nifty on a high-latency link where you know the server won't be modified from under you.

1.23	23-Aug-2007	pooka	branches: 1.23.2; Prevent crash in case there is more than one reader for the same directory concurrently. Might need to revisit the method used here later, though.
1.22	27-Jul-2007	pooka	branches: 1.22.4; Track memory mappings. Close file handles already in close() if there are no active mappings, otherwise do the standard inactive() run.
1.21	07-Jul-2007	pooka	adapt to puffs_framebuf changes
1.20	06-Jun-2007	pooka	Move puffs to a two clause license where it already isn't so. And as agc pointed out, even files with the third clause were already effectively two clause because of a slight bug in the language...
1.19	20-May-2007	pooka	Observe that when doing ls -l, the attributes of the first file getattr are usually still outstanding when we already would like the result. Instead of issueing another stat which will be serviced only after all the other entries in the directory, record all the outgoing readdir getattr buffers and if we encounter an outstanding request when we need to fetch attrs, do a puffs_framev_framebuf_ccpromote() wait for it instead of firing off the second query. This shaves almost 10% off the time for ls -lR. Also, get rid of the SUPERREADDIR conditional, since it has penetrated the code quite a bit and the #ifdef SUPERREADDIRs were starting to look like tagliatelle alla bolognese (n.b. I love how it looks, but I wouldn't like it either if my tagliatelle alla bolognese looked like psshfs code). Maybe it should be re-introduced in the form of a switch?
1.18	20-May-2007	pooka	Implement SUPERREADDIR (like nfs readdirplus) getattr cache warming a bit differently: when reading the directory, store all getattr caching queries and fire off only when the directory read is complete. That way the common sequence is not [readdir, lots of async getattr requests, readdir EOF] but rather [readdir, readdir EOF, lots of async getattr]. This speeds up ls -lR by about 25% (on my LAN).
1.17	18-May-2007	pooka	remove obvious incorrect assert() from doreclaim() and remove the whole PSN_NUKED bit - it's not very useful because of the noref setback.
1.16	18-May-2007	pooka	* use NOREF setback to prompt immediate (well, once the kernel reference count goes to 0) reclaim of deleted nodes as opposed to waiting for the system to start reclaiming the freelist * combine some nodeflags from different variable to one status variable

But verifying it exists and fixing it will have to wait for another day.
1.49	17-Feb-2010	pooka	Save "." attributes in readdir. This fixes the root link count after readdir is called for the root dir the first time (yes, there's still a window of wrong link count after the fs is mounted. it's currently quite difficult to call sftp_readdir() from outside the main loop). Should fix "find /mnt" problem for a mountpoint with more than the "guessed" amount of subdirectories, as reported by dyoung.
1.48	07-Jan-2010	pooka	Add -u and -g, which allow to remap one (local,remote) uidgid, i.e. umapfs without the fuss.
1.47	05-Nov-2009	pooka	more lp64 it's-a-sign! fixes
1.46	20-May-2009	pooka	Introduce -c [12], which can be used to open 1 or 2 ssh connections to the server. If "2" is specified, a separate connection is used for data and directory operations. Using two connections can significantly increase directory operation performance on a saturated link, at least up to 30x faster.
1.45	13-Dec-2007	pooka	Record inode number in psshfs_dir also for already instantiated nodes when doing readdir. This makes pwd work again for cases where getcwd() actually has to do the "READDIR + compare inode numbers" trick. Yet another problem reported by jmmv.
1.44	13-Dec-2007	pooka	blink, remember to update comment too
1.43	13-Dec-2007	pooka	Do previous in a way which causes less waste of potential inode numbers.
1.42	12-Dec-2007	pooka	Fix lossage noticed by jmmv (mostly for -t 0 mounts) and make sure a node always has the inode number set. And since I'm feeling generous, sprinkle a few comments around the affected areas (mostly so that I'd remember what in the world the code is trying to do).
1.41	07-Dec-2007	pooka	Don't use puffs_cc_getusermount()
1.40	07-Dec-2007	pooka	Get rid of a lot of extra complexity due to doing separate getattr requests in readdir - just use the results from the readdir rpc.
1.39	05-Dec-2007	pooka	Invalidate namecache for a directory only if we've already read it at least once.
1.38	30-Nov-2007	pooka	Rototill. Ok, ok, a few more words about it: stop holding puffs_cc as a holy value and passing it around to almost every possible place (popquiz: which kernel variable does this remind you of?). Instead, pass the natural choice, puffs_usermount, and fetch puffs_cc via puffs_cc_getcc() only in routines which actually need it. This not only simplifies code, but (thanks to the introduction of puffs_cc_getcc()) enables constructs which weren't previously sanely possible, say layering as a curious example. There's still a little to do on this front, but this was the major fs interface blast.
1.37	30-Nov-2007	pooka	Introduce the concept of lazyopens. This means that when a file handle open is requested, it is waited for only if the node was not previously succesfully opened. The actual wait for the file handle happens only when the file handle is actually needed (read or write). This in turn has the effect that reading cached files will be quick instead of waiting for the file handle from the sftp server first. The wait previously could be very long if there were serveral hundred k of outstanding requests in a limited-bandwidth link. The code is in some need of serious handholding, but it works, so I'll leave that as "future work".
1.36	16-Nov-2007	pooka	If a regular file was remotely updated and a readdir was done on the directory which contained the file before a getattr on the file itself, the locally cached mtime would be updated without invalidating the kernel page cache. Thus incorrect data would be returned when the node was read afterwards as the node size wouldn't match the data length in the page cache. Fix the problem by making all vattr-setting routines use the same code. Problem noticed again by jmmv & atf (and again by running atf over psshfs ... sometimes you're the windshield, sometimes you're the bug)
1.35	16-Nov-2007	jmmv	Drop trailing whitespace. On behalf of pooka.
1.34	16-Nov-2007	pooka	When checking if the file page cache should be invalidated, compare against cached mtime instead of attrread - attrread can be reset these days by sending SIGHUP. Problem noticed by jmmv & atf (well.. namely by using atf through psshfs).
1.33	10-Nov-2007	pooka	Cache readlink results similarly to attributes. Makes "cd" fast for a slow connection if a symlink is along the path. (this should be done elsewhere, but I want it for sshfs now)
1.32	08-Nov-2007	pooka	Make it possible to force attribute/directory cache re-read by sending SIGHUP to mount_psshfs.
1.31	08-Nov-2007	pooka	Make attribute & directory content caching timeout a command line option. Use -t -1 to never expire, which is nifty on a high-latency link where you know the server won't be modified from under you.
1.30	20-Oct-2007	pooka	Add option -r to specify maximum number of active read requests for each node. Setting this to a small number can be used to improve interactive performance on low-bandwidth links when performing bulk data reads. Of course I could also open separate pipes for bulk and other, but this was quicker and less intrusive and doesn't require authenticating twice.
1.29	08-Sep-2007	pooka	Free longname in all error branches. CID: 4545
1.28	25-Aug-2007	pooka	branches: 1.28.2; error branch management. CID 4503
1.27	25-Aug-2007	pooka	jump to correct error branch. CID 4500
1.26	23-Aug-2007	pooka	Prevent crash in case there is more than one reader for the same directory concurrently. Might need to revisit the method used here later, though.
1.25	21-Jun-2007	pooka	print warning if directory cache invalidation fails
1.24	06-Jun-2007	pooka	Move puffs to a two clause license where it already isn't so. And as agc pointed out, even files with the third clause were already effectively two clause because of a slight bug in the language...
1.23	20-May-2007	pooka	In case we are really tight on vnodes, the directory vnode might be reclaimed from under while we are warming the getattr cache. Shuffle some code to prevent the effects. Theoretically the race is still possible, but I don't think it will happen in practice. In any case, the code could benefit from some more dusting.
1.22	20-May-2007	pooka	Observe that when doing ls -l, the attributes of the first file getattr are usually still outstanding when we already would like the result. Instead of issueing another stat which will be serviced only after all the other entries in the directory, record all the outgoing readdir getattr buffers and if we encounter an outstanding request when we need to fetch attrs, do a puffs_framev_framebuf_ccpromote() wait for it instead of firing off the second query. This shaves almost 10% off the time for ls -lR. Also, get rid of the SUPERREADDIR conditional, since it has penetrated the code quite a bit and the #ifdef SUPERREADDIRs were starting to look like tagliatelle alla bolognese (n.b. I love how it looks, but I wouldn't like it either if my tagliatelle alla bolognese looked like psshfs code). Maybe it should be re-introduced in the form of a switch?
1.21	20-May-2007	pooka	Implement SUPERREADDIR (like nfs readdirplus) getattr cache warming a bit differently: when reading the directory, store all getattr caching queries and fire off only when the directory read is complete. That way the common sequence is not [readdir, lots of async getattr requests, readdir EOF] but rather [readdir, readdir EOF, lots of async getattr]. This speeds up ls -lR by about 25% (on my LAN).
1.20	18-May-2007	pooka	remove obvious incorrect assert() from doreclaim() and remove the whole PSN_NUKED bit - it's not very useful because of the noref setback.
1.19	18-May-2007	pooka	* use NOREF setback to prompt immediate (well, once the kernel reference count goes to 0) reclaim of deleted nodes as opposed to waiting for the system to start reclaiming the freelist * combine some nodeflags from different variable to one status variable
1.18	16-May-2007	pooka	Add error parameter to puffs_framev_cb to signal if there is a result of if the function should just do resource cleanup.
1.17	15-May-2007	pooka	remember to free longname if getting vattr from the message fails CID 4486
1.16	15-May-2007	pooka	adapt to "step 3" of puffs_framebuf changes
1.15	11-May-2007	pooka	adapt to puffs_framebuf changes
1.14	05-May-2007	pooka	Adapt to use puffs_framebuf. This gets rid of most of the duplicated code between mount_psshfs and mount_9p and clarifies the code structure.
1.13	12-Apr-2007	pooka	Hide struct puffs_usermount from the rest of the world and provide accessors for interesting data in it. Namely, you can now get pu->pu_privdata with puffs_getspecific(), pu->pu_pn_root with puffs_set/getroot() and pu->pu_maxreqlen with puffs_getmaxreqlen().
1.12	22-Mar-2007	pooka	In case lookup from the directory listing fails, try statting the target before giving up. Makes it possible to access files from -r+x directories.
1.11	13-Mar-2007	pooka	* don't require a directory entry to exist for a reclaimee node. this can happen legally when a file is removed from backing storage not using this sshfs instance, a readdir is executed for the parent directory and only then the node gets reclaimed. * now that there is a mechanism in place which does not require a pcc to do an sftp transaction, do not yield() in operations where the final transaction is something where we don't care about the return value (e.g. close handle). speedup benefit for no cost.
1.10	27-Feb-2007	pooka	one more size_t -> uint32_t
1.9	15-Feb-2007	pooka	Support reclaim. To support dotdot lookup, here we leave the reclaimed nodes hanging until all their children have been reclaimed and then reclaim everything we can as far up to root as possible. This is because the file system structures are currently interlinked in a fashion which would make dotdot lookup based on purely a path instead of a in-memory node parent member pointer very difficult. Yes, this deserves a closer look some day.
1.8	09-Feb-2007	pooka	Implement "superreaddir". This issues a getattr for all the directory entries already in readdir and caches the results instead of waiting for each individial getattr from the kernel. For high-latency links the difference in "ls -l" is quite astounding and even on my lan "ls -lR" is faster than for nfs in a normal directory hierarchy (i.e. not one artifically setup to have thousands of files per directory). TODO: implement some sort of bandwidth/latency measurement in the code and enable or disable this option based on than information (and a command-line flag).
1.7	15-Jan-2007	pooka	* adapt to libpuffs path changes * fix bug in rename
1.6	11-Jan-2007	pooka	Give nukenode a destroy flag. If given, it completely wipes out the node and directory cache (for directories). Otherwise it just nukes directory entry information. The latter case is used when renaming.
1.5	09-Jan-2007	pooka	Invalidate kernel name cache for a directory when (re-)reading directory contents from the server.
1.4	09-Jan-2007	pooka	Mark invalid attributes as invalid. Fixes stuff such a cp'ing files when cp uses mmap(). Also makes attributes appear correct.
1.3	07-Jan-2007	pooka	properly carry fileid for directory entries, fixes pwd
1.2	07-Jan-2007	pooka	fix link count calculation for directories

(i looked at many different ones, and while perhaps 60-80% were already properly aligned, it wasn't clear to me that the uses were always coming from sane data vs network alignment, so it doesn't seem safe to remove packed without careful research for each affect struct.) clang already warned (and was not erroring) for many of these cases, but gcc picked up dozens more.

1.19	30-Aug-2019	brad	The cleaner is compiled into rump_lfs and executed as a thread. Pass in the raw device using the new -J option. This avoids the use of getdiskrawname which is not particularly rump safe in this context and insures that the rump container device is used for cleaning, not the outer device.
1.18	02-Aug-2015	dholland	branches: 1.18.16; 1.18.18; Use the lfs header file and lfs's mount args struct, not ufsmount.h and the ffs mount args struct, for mounting lfs. (they are the same, so this doesn't matter yet, but still...)
1.17	10-Jan-2013	riastradh	After mount_lfs_parseargs, reset getopt for lfs_cleaner_main.
1.16	03-Mar-2010	pooka	branches: 1.16.6; 1.16.12; Give usage() a chance. XXX: UKFS_DEVICE_ARGVPROBE() interface
1.15	12-Jan-2010	pooka	Make r/w servers unmount themselves cleanly upon receiving SIGINT/TERM.
1.14	13-Dec-2009	pooka	Call ukfs_part_release(). For completeness and educational value.
1.13	03-Dec-2009	pooka	Adapt ukfs users to the new ukfs_part interface.
1.12	05-Nov-2009	pooka	Link fs components into binary instead of loading dynamically now that it's possible (dependency handling changes to rumpuser_dl).
1.11	05-Nov-2009	pooka	Need to p2k_init() (i.e. fork()) earlier to not lose threads created in rump_init().
1.10	18-Oct-2009	pooka	adapt to new p2k interfaces
1.9	14-Oct-2009	pooka	Adjust names of external rump control interfaces to match the new rump_pub namespace.

1.5	21-Jul-2009	pooka	don't need absolute paths for fs component names
1.4	21-Jul-2009	pooka	Make rump_lfs work again: load fs components dynamically instead of trying to link them in on the command line and get pounded by link set failage.
1.3	04-Sep-2008	pooka	branches: 1.3.2; adjust copyright to match reality. no functional change.
1.2	05-Aug-2008	pooka	Refactor mount utilities to provide a mount_fs_parseargs() routine. Use this routine both in mount_fs and rump_fs to provide equivalent command line parameters and therefore usage interchangeability. While doing this, combine some common mountgoop to mountprog.h
1.1	29-Jul-2008	pooka	Install rump libraries and utilities to the base system and remove the private non-installed build infrastructure from sys/rump. breakdown of commit: * install relevant headers into /usr/include/rump * build sys/rump/librump/rumpuser and sys/rump/librump/rumpkern from src/lib and install as librumpuser and librump, respectively + this retains the ability to test a librump build with just the kernel sources at hand * move sys/rump/fs/lib/libukfs and sys/rump/fs/lib/libp2k to src/lib for general consumption, they are not kernel-space dwellers anyway * build and install sys/rump/fs/lib/lib$fs as librumpfs_$fs * add chapter 3 manual pages for rump, rumpuser, ukfs and p2k * build and install userspace kernel file system daemons if MKPUFFS=yes is spexified * retire fsconsole for now, it will make a comeback with an actually implemented version shortly

1.18.18.1	02-Sep-2019	martin	Pull up following revision(s) (requested by brad in ticket #110): libexec/lfs_cleanerd/lfs_cleanerd.c: revision 1.59 libexec/lfs_cleanerd/lfs_cleanerd.8: revision 1.19 sbin/resize_lfs/resize_lfs.c: revision 1.15 usr.sbin/puffs/rump_lfs/rump_lfs.c: revision 1.19 libexec/lfs_cleanerd/lfs_cleanerd.c: revision 1.60 lib/libutil/getdiskrawname.c: revision 1.6 tests/fs/common/fstest_lfs.c: revision 1.7 Use getdiskrawname to find the device name. Reviewed by Christos - Teach getdiskrawname and getdiskcookedname about zvols. Reviewed by Christos - Add support for passing the raw device name separate from the filesystem. This is useful in the case where the cleaner is compiled into code, such as rump_lfs and the ATF tests. This helps to fix bin/54488 - The cleaner is compiled into rump_lfs and executed as a thread. Pass in the raw device using the new -J option. This avoids the use of getdiskrawname which is not particularly rump safe in this context and insures that the rump container device is used for cleaning, not the outer device.

1.4	21-Aug-2009	skrll	No-one wins in rump vs link sets. XXX Someone(tm) needs to fix this properly.
1.3	18-Jan-2009	he	Change the use of formally undocumented features, which have now been made to fail. Specifically, change .ifdef(SYMBOL) -> .ifdef SYMBOL or .if defined(SYMBOL), and corresponding for .ifndef. Also correct one error in lib/libm/Makefile (.ifdef (${MKCOMPLEX} != "no")?!?).

1.10	12-Jan-2010	pooka	Make r/w servers unmount themselves cleanly upon receiving SIGINT/TERM.
1.9	18-Oct-2009	pooka	Remove threading ifdefs. It was never easy to run the nfs client without threads, but now it's even more difficult due to sillyrename using workqueue, so whoever wants to do it will have to take to manual fiddling.
1.8	18-Oct-2009	pooka	Use write through cache here too. Doesn't make the same kind of difference as with smbfs since nfs is "stateless", but better to have the data on the server ASAP in case some other nods wants to use it.
1.7	11-Jan-2009	pooka	Default to threading, non-threaded debug mode can be compiled separately. Useful if running this from fstab.
1.6	10-Jan-2009	pooka	Don't compile diagnostic code which accesses kernel symbols directly. Will fail now since not all archs have the same symbol names.
1.5	08-Jan-2009	pooka	For applications which naughtily reach over to the rump kernel namespace without using proper interfaces, do a little namespace compensation.
1.4	12-Dec-2008	pooka	Do some nasty manual tricks and treats to avoid having to call rump_init() here (creating threads before we ask p2k to detach from console is bad).
1.3	26-Nov-2008	pooka	Try to honor rump_threads by not creating iothreads if threads are off.
1.2	14-Nov-2008	pooka	Don't set PUFFS_FLAG_OPDUMP by default.
1.1	16-Oct-2008	pooka	Add & enable rump_nfs.
1.1	08-Mar-2010	pooka	Not Quite MFS Instead of copulating with newfs to produce a new FFS image into memory, mmap() a given existing image and pass that as the backing store. If -s is given, mmap is done with MAP_SHARED and changes are kept across mounts, else MAP_COPY (i.e. MAP_PRIVATE for us) is done and changes are lost when the server exits.

1.4	02-Sep-2008	pooka	branches: 1.4.2; Make syspuffs mount code supply mount_syspuffs_parseargs() like the other mount binaries do. Now syspuffs can be used to run all puffs file systems as utilities. This includes fuse file systems and becomes interesting with the fs-utils project. We can now do e.g. this: ReFUSE ntfs-3g: golem> echo hello \| fsu_write/fsu_write ntfs-3g puffs ~/img/ntfs.img dafile golem> fsu_cat/fsu_cat ntfs-3g puffs ~/img/ntfs.img dafile hello golem> puffs sysctlfs: golem> fsu_ls/fsu_ls mount_sysctlfs puffs sysctl -l ddb total 0 -r-xr-xr-x 1 pooka users 1 Sep 2 22:11 commandonenter -r-xr-xr-x 1 pooka users 2 Sep 2 22:11 fromconsole -r-xr-xr-x 1 pooka users 3 Sep 2 22:11 lines -r-xr-xr-x 1 pooka users 8 Sep 2 22:11 maxoff -r-xr-xr-x 1 pooka users 3 Sep 2 22:11 maxwidth -r-xr-xr-x 1 pooka users 2 Sep 2 22:11 onpanic -r-xr-xr-x 1 pooka users 3 Sep 2 22:11 radix -r-xr-xr-x 1 pooka users 2 Sep 2 22:11 tabstops -r-xr-xr-x 1 pooka users 2 Sep 2 22:11 tee_msgbuf Same works for psshfs etcetc. In other words, this provides total integration for "normal" in-kernel file systems and puffs/fuse file systems on the ukfs library level. Note: implementation is still "first stab" and the fs-utils usage will no doubt change.
1.3	11-Aug-2008	pooka	We can actually simply use execvp() instead of /bin/sh for exec-and-pathsearch-with-environ. Thanks to bad for pointing this out & apb + blymn for some discussion.
1.2	08-Aug-2008	pooka	exec file server via sh -c to get the benefit of PATH search.
1.1	29-Jul-2008	pooka	Install rump libraries and utilities to the base system and remove the private non-installed build infrastructure from sys/rump. breakdown of commit: * install relevant headers into /usr/include/rump * build sys/rump/librump/rumpuser and sys/rump/librump/rumpkern from src/lib and install as librumpuser and librump, respectively + this retains the ability to test a librump build with just the kernel sources at hand * move sys/rump/fs/lib/libukfs and sys/rump/fs/lib/libp2k to src/lib for general consumption, they are not kernel-space dwellers anyway * build and install sys/rump/fs/lib/lib$fs as librumpfs_$fs * add chapter 3 manual pages for rump, rumpuser, ukfs and p2k * build and install userspace kernel file system daemons if MKPUFFS=yes is spexified * retire fsconsole for now, it will make a comeback with an actually implemented version shortly
