This is a minor update of the patches I posted last week, I would like to add this into linux-next now, but would still do changes if there are concerns about the contents. The first version did not see a lot of replies, which could mean that either everyone is happy with it, or that it was largely ignored.
See also the article at https://lwn.net/Articles/776435/.
Changes since v1:
- posting as a combined series for simplicity - dropped one mips patch that was merged as a 5.0 fix - reworked s390 compat syscall handling (posted separately) and rebased on top of that series - minor fixes for arm64 and powerpc - added alpha statfs64 interfaces - added alpha get{eg,eu,g,p,u,pp}id()

---- v1 description for cleanup: The system call tables have diverged a bit over the years, and a number of the recent additions never made it into all architectures, for one reason or another.
This is an attempt to clean it up as far as we can without breaking compatibility, doing a number of steps:
- Add system calls that have not yet been integrated into all architectures but that we definitely want there.
- Add the separate ipc syscalls on all architectures that traditionally only had sys_ipc(). This version is done without support for IPC_OLD that is we have in sys_ipc. The new semtimedop_time64 syscall will only be added here, not in sys_ipc
- Add syscall numbers for a couple of syscalls that we probably don't need everywhere, in particular pkey_* and rseq, for the purpose of symmetry: if it's in asm-generic/unistd.h, it makes sense to have it everywhere.
- Prepare for having the same system call numbers for any future calls. In combination with the generated tables, this hopefully makes it easier to add new calls across all architectures together.
Most of the contents of this series are unrelated to the actual y2038 work, but for the moment, that second series is based on this one. If there are any concerns about changes here, I can drop or rewrite any individual patch in this series.
My plan is to merge any patches in this series that are found to be good together with the y2038 patches for linux-5.1, so please review and provide Acks for merging through my tree, or pick them up for 5.0 if they seem urgent enough.
v1 description for y2038 patches:
This series finally gets us to the point of having system calls with 64-bit time_t on all architectures, after a long time of incremental preparation patches.
There was actually one conversion that I missed during the summer, i.e. Deepa's timex series, which I now updated based the 5.0-rc1 changes and review comments.
I hope that the actual conversion should be uncontroversial by now, even if some of the patches are rather large.
The one area that may need a little discussion is for the system call numbers assigned in the final patch: Can we get consensus on whether the idea of using the same numbers on all architectures, as well as my choice of numbers makes sense here?
So far, I have done a lot of build testing across most architectures, which has found a number of bugs. I have also done an LTP run on arm32 with existing user space, but not on the other architectures. I did LTP tests with a modified musl libc[2] last summer on an older version of this series to make sure that the new 64-bit time_t interfaces work. The version there will need updates for testing with this new kernel patch series; I plan to do that next.
For testing, the series plus the preparatory patches is available at [3]. Once there is a general agreement on this series and I have done more tests for the new system calls, I plan to add this to linux-next through my asm-generic tree or Thomas' timers tree.
Please review and test!

Other architectures commonly use __NR_umount2 for sys_umount, only ia64 and alpha use __NR_umount here. In order to synchronize the generated tables, use umount2 like everyone else, and add back the old name from asm/unistd.h for compatibility.
The __IGNORE_* lines are now all obsolete and can be removed as a side-effect.

Most architectures have assigned numbers for both seccomp and perf_event_open, even when they do not implement either.
ia64 is an exception here, so for consistency lets add numbers for both of them. Unless CONFIG_PERF_EVENTS and CONFIG_SECCOMP are implemented, the system calls just return -ENOSYS.

For shmat, alpha uses the osf_shmat name, we can do the same thing here, which means we don't have to add an entry in the __IGNORE list now that shmat is mandatory everywhere
alarm, creat, pause, time, and utime are optional everywhere these days, no need to list them here any more.
I considered also adding the regular versions of the get*id system calls that have different names and calling conventions on alpha, which would further help unify the syscall ABI, but for now I decided against that.

The migrate_pages system call has an assigned number on all architectures except ARM. When it got added initially in commit d80ade7b3231 ("ARM: Fix warning: #warning syscall migrate_pages not implemented"), it was intentionally left out based on the observation that there are no 32-bit ARM NUMA systems.
However, there are now arm64 NUMA machines that can in theory run 32-bit kernels (actually enabling NUMA there would require additional work) as well as 32-bit user space on 64-bit kernels, so that argument is no longer very strong.
Assigning the number lets us use the system call on 64-bit kernels as well as providing a more consistent set of syscalls across architectures.

For the arm64 part:
Acked-by: Catalin Marinas catalin.marinas@arm.com
A couple of architectures including arm64 already implement the kexec_file_load system call, on many others we have assigned a system call number for it, but not implemented it yet.
Adding the number in arch/arm/ lets us use the system call on arm64 systems in compat mode, and also reduces the number of differences between architectures. If we want to implement kexec_file_load on ARM in the future, the number assignment means that kexec tools can already be built with the now current set of kernel headers.

I presume on arm32 this would still return -ENOSYS.
Yes, I already checked. If CONFIG_KEXEC_FILE is not set, then kernel/kexec_file.c is not built, and we fall back to the stub in kernel/sys_ni.c.
Most architectures have assigned a numbers for the seccomp syscall even when they do not implement it.
m68k is an exception here, so for consistency lets add the number. Unless CONFIG_SECCOMP is implemented, the system call just returns -ENOSYS.

When I merged this patch, the file was accidentally left intact instead of being removed, which means any changes to syscall.tbl have no effect.

The behavior of these system calls is slightly different between architectures, as determined by the CONFIG_ARCH_WANT_IPC_PARSE_VERSION symbol. Most architectures that implement the split IPC syscalls don't set that symbol and only get the modern version, but alpha, arm, microblaze, mips-n32, mips-n64 and xtensa expect the caller to pass the IPC_64 flag.
For the architectures that so far only implement sys_ipc(), i.e. m68k, mips-o32, powerpc, s390, sh, sparc, and x86-32, we want the new behavior when adding the split syscalls, so we need to distinguish between the two groups of architectures.
The method I picked for this distinction is to have a separate system call entry point: sys_old_*ctl() now uses ipc_parse_version, while sys_*ctl() does not. The system call tables of the five architectures are changed accordingly.
As an additional benefit, we no longer need the configuration specific definition for ipc_parse_version(), it always does the same thing now, but simply won't get called on architectures with the modern interface.
A small downside is that on architectures that do set ARCH_WANT_IPC_PARSE_VERSION, we now have an extra set of entry points that are never called. They only add a few bytes of bloat, so it seems better to keep them compared to adding yet another Kconfig symbol. I considered adding new syscall numbers for the IPC_64 variants for consistency, but decided against that for now.

The IPC system call handling is highly inconsistent across architectures, some use sys_ipc, some use separate calls, and some use both. We also have some architectures that require passing IPC_64 in the flags, and others that set it implicitly.
For the additon of a y2083 safe semtimedop() system call, I chose to only support the separate entry points, but that requires first supporting the regular ones with their own syscall numbers.
The IPC_64 is now implied by the new semctl/shmctl/msgctl system calls even on the architectures that require passing it with the ipc() multiplexer.
I'm not adding the new semtimedop() or semop() on 32-bit architectures, those will get implemented using the new semtimedop_time64() version that gets added along with the other time64 calls. Three 64-bit architectures (powerpc, s390 and sparc) get semtimedop().
Signed-off-by: Arnd Bergmann arnd@arndb.de --- One aspect here that might be a bit controversial is the use of the same system call numbers across all architectures, synchronizing all of them with the x86-32 numbers.

The IPC_64 is now implied by the new semctl/shmctl/msgctl system calls even on the architectures that require passing it with the ipc() multiplexer.
I'm not adding the new semtimedop() or semop() on 32-bit architectures, those will get implemented using the new semtimedop_time64() version that gets added along with the other time64 calls. Three 64-bit architectures (powerpc, s390 and sparc) get semtimedop().

One aspect here that might be a bit controversial is the use of the same system call numbers across all architectures, synchronizing all of them with the x86-32 numbers. With the new syscall.tbl files, I hope we can just keep doing that in the future, and no longer require the architecture maintainers to assign a number.
This is mainly useful for implementers of the C libraries: if we can add future system calls everywhere at the same time, using a particular version of the kernel headers also guarantees that the system call number macro is visible.

Most architectures define system call numbers for the rseq and pkey system calls, even when they don't support the features, and perhaps never will.
Only a few architectures are missing these, so just define them anyway for consistency. If we decide to add them later to one of these, the system call numbers won't get out of sync then.

While there is an old osf_statfs64 system call that returns additional data, this has some other quirks and does not get used in glibc.
I considered making the stat64 structure layout compatible with with the one used by the kernel on most other 64 bit architecture that implement it (ia64, parisc, powerpc, and sparc), but in the end decided to stay with the one that was traditionally defined in the alpha headers but not used, since this is also what glibc exposes to user space.

Alpha has traditionally followed the OSF1 calling conventions here, with its getxpid, getxuid, getxgid system calls returning two different values in separate registers.
Following what glibc has done here, we can define getpid, getuid and getgid to be aliases for getxpid, getxuid and getxgid respectively, and add new system call numbers for getppid, geteuid and getegid.

For the s390 bits: Acked-by: Heiko Carstens heiko.carstens@de.ibm.com
We want to reuse the compat_timex handling on 32-bit architectures the same way we are using the compat handling for timespec when moving to 64-bit time_t.
Move all definitions related to compat_timex out of the compat code into the normal timekeeping code, along with a rename to old_timex32, corresponding to the timespec/timeval structures, and make it controlled by CONFIG_COMPAT_32BIT_TIME, which 32-bit architectures will then select.

From: Deepa Dinamani deepa.kernel@gmail.com
struct timex uses struct timeval internally. struct timeval is not y2038 safe. Introduce a new UAPI type struct __kernel_timex that is y2038 safe.
struct __kernel_timex uses a timeval type that is similar to struct __kernel_timespec which preserves the same structure size across 32 bit and 64 bit ABIs. struct __kernel_timex also restructures other members of the structure to make the structure the same on 64 bit and 32 bit architectures. Note that struct __kernel_timex is the same as struct timex on a 64 bit architecture.
The above solution is similar to other new y2038 syscalls that are being introduced: both 32 bit and 64 bit ABIs have a common entry, and the compat entry supports the old 32 bit syscall interface.
Alternatives considered were: 1. Add new time type to struct timex that makes use of padded bits. This time type could be based on the struct __kernel_timespec. modes will use a flag to notify which time structure should be used internally. This needs some application level changes on both 64 bit and 32 bit architectures. Although 64 bit machines could continue to use the older timeval structure without any changes.
2. Add a new u8 type to struct timex that makes use of padded bits. This can be used to save higher order tv_sec bits. modes will use a flag to notify presence of such a type. This will need some application level changes on 32 bit architectures.
3. Add a new compat_timex structure that differs in only the size of the time type; keep rest of struct timex the same. This requires extra syscalls to manage all 3 cases on 64 bit architectures. This will not need any application level changes but will add more complexity from kernel side.

A small typo has crept into the y2038 conversion of the timer_settime system call. So far this was completely harmless, but once we start using the new version, this has to be fixed.

sparc64 is the only architecture on Linux that has a 'timeval' definition with a 32-bit tv_usec but a 64-bit tv_sec. This causes problems for sparc32 compat mode when we convert it to use the new __kernel_timex type that has the same layout as all other 64-bit architectures.
To avoid adding sparc64 specific code into the generic adjtimex implementation, this adds a wrapper in the sparc64 system call handling that converts the sparc64 'timex' into the new '__kernel_timex'.
At this point, the two structures are defined to be identical, but that will change in the next step once we convert sparc32.

From: Deepa Dinamani deepa.kernel@gmail.com
struct timex is not y2038 safe. Replace all uses of timex with y2038 safe __kernel_timex.
Note that struct __kernel_timex is an ABI interface definition. We could define a new structure based on __kernel_timex that is only available internally instead. Right now, there isn't a strong motivation for this as the structure is isolated to a few defined struct timex interfaces and such a structure would be exactly the same as struct timex.
The patch was generated by the following coccinelle script:

From: Deepa Dinamani deepa.kernel@gmail.com
struct timex is not y2038 safe. Switch all the syscall apis to use y2038 safe __kernel_timex.
Note that sys_adjtimex() does not have a y2038 safe solution. C libraries can implement it by calling clock_adjtime(CLOCK_REALTIME, ...).

x32 has always followed the time64 calling conventions of these syscalls, which required a special hack in compat_get_timespec aka get_old_timespec32 to continue working.
Since we now have the time64 syscalls, use those explicitly.

A lot of system calls that pass a time_t somewhere have an implementation using a COMPAT_SYSCALL_DEFINEx() on 64-bit architectures, and have been reworked so that this implementation can now be used on 32-bit architectures as well.
The missing step is to redefine them using the regular SYSCALL_DEFINEx() to get them out of the compat namespace and make it possible to build them on 32-bit architectures.
Any system call that ends in 'time' gets a '32' suffix on its name for that version, while the others get a '_time32' suffix, to distinguish them from the normal version, which takes a 64-bit time argument in the future.
In this step, only 64-bit architectures are changed, doing this rename first lets us avoid touching the 32-bit architectures twice.

A lot of system calls that pass a time_t somewhere have an implementation using a COMPAT_SYSCALL_DEFINEx() on 64-bit architectures, and have been reworked so that this implementation can now be used on 32-bit architectures as well.
The missing step is to redefine them using the regular SYSCALL_DEFINEx() to get them out of the compat namespace and make it possible to build them on 32-bit architectures.
Any system call that ends in 'time' gets a '32' suffix on its name for that version, while the others get a '_time32' suffix, to distinguish them from the normal version, which takes a 64-bit time argument in the future.
In this step, only 64-bit architectures are changed, doing this rename first lets us avoid touching the 32-bit architectures twice.

For arm64:
Acked-by: Catalin Marinas catalin.marinas@arm.com
This is the big flip, where all 32-bit architectures set COMPAT_32BIT_TIME abd use the _time32 system calls from the former compat layer instead of the system calls that take __kernel_timespec and similar arguments.
The temporary redirects for __kernel_timespec, __kernel_itimerspec and __kernel_timex can get removed with this.
It would be easy to split this commit by architecture, but with the new generated system call tables, it's easy enough to do it all at once, which makes it a little easier to check that the changes are the same in each table.

The temporary redirects for __kernel_timespec, __kernel_itimerspec and __kernel_timex can get removed with this.
It would be easy to split this commit by architecture, but with the new generated system call tables, it's easy enough to do it all at once, which makes it a little easier to check that the changes are the same in each table.

We now use 64-bit time_t on all architectures, so the __kernel_timex, __kernel_timeval and __kernel_timespec redirects can be removed after having served their purpose.
This makes it all much less confusing, as the __kernel_* types now always refer to the same layout based on 64-bit time_t across all 32-bit and 64-bit architectures.

/* * Mode codes (timex.mode)
The time, stime, utime, utimes, and futimesat system calls are only used on older architectures, and we do not provide y2038 safe variants of them, as they are replaced by clock_gettime64, clock_settime64, and utimensat_time64.
However, for consistency it seems better to have the 32-bit architectures that still use them call the "time32" entry points (leaving the traditional handlers for the 64-bit architectures), like we do for system calls that now require two versions.
Note: We used to always define __ARCH_WANT_SYS_TIME and __ARCH_WANT_SYS_UTIME and only set __ARCH_WANT_COMPAT_SYS_TIME and __ARCH_WANT_SYS_UTIME32 for compat mode on 64-bit kernels. Now this is reversed: only 64-bit architectures set __ARCH_WANT_SYS_TIME/UTIME, while we need __ARCH_WANT_SYS_TIME32/UTIME32 for 32-bit architectures and compat mode. The resulting asm/unistd.h changes look a bit counterintuitive.
This is only a cleanup patch and it should not change any behavior.

For the s390 bits: Acked-by: Heiko Carstens heiko.carstens@de.ibm.com
This adds 21 new system calls on each ABI that has 32-bit time_t today. All of these have the exact same semantics as their existing counterparts, and the new ones all have macro names that end in 'time64' for clarification.
This gets us to the point of being able to safely use a C library that has 64-bit time_t in user space. There are still a couple of loose ends to tie up in various areas of the code, but this is the big one, and should be entirely uncontroversial at this point.
In particular, there are four system calls (getitimer, setitimer, waitid, and getrusage) that don't have a 64-bit counterpart yet, but these can all be safely implemented in the C library by wrapping around the existing system calls because the 32-bit time_t they pass only counts elapsed time, not time since the epoch. They will be dealt with later.
Signed-off-by: Arnd Bergmann arnd@arndb.de --- The one point that still needs to be agreed on is the actual number assignment. Following the earlier patch that added the sysv IPC calls with common numbers where possible, I also tried the same here, using consistent numbers on all 32-bit architectures.
There are a couple of minor issues with this:
- On asm-generic, we now leave the numbers from 295 to 402 unassigned, which wastes a small amount of kernel .data segment. Originally I had asm-generic start at 300 and everyone else start at 400 here, which was also not perfect, and we have gone beyond 400 already, so I ended up just using the same numbers as the rest here.
- Once we get to 512, we clash with the x32 numbers (unless we remove x32 support first), and probably have to skip a few more. I also considered using the 512..547 space for 32-bit-only calls (which never clash with x32), but that also seems to add a bit of complexity.
- On alpha, we have already used up the space up to 527 (with a small hole between 261 and 299). We could sync up with that as well, but my feeling was that alpha syscalls are already special enough that I don't care.

This gets us to the point of being able to safely use a C library that has 64-bit time_t in user space. There are still a couple of loose ends to tie up in various areas of the code, but this is the big one, and should be entirely uncontroversial at this point.
In particular, there are four system calls (getitimer, setitimer, waitid, and getrusage) that don't have a 64-bit counterpart yet, but these can all be safely implemented in the C library by wrapping around the existing system calls because the 32-bit time_t they pass only counts elapsed time, not time since the epoch.

The one point that still needs to be agreed on is the actual number assignment. Following the earlier patch that added the sysv IPC calls with common numbers where possible, I also tried the same here, using consistent numbers on all 32-bit architectures.
There are a couple of minor issues with this:
On asm-generic, we now leave the numbers from 295 to 402 unassigned, which wastes a small amount of kernel .data segment. Originally I had asm-generic start at 300 and everyone else start at 400 here, which was also not perfect, and we have gone beyond 400 already, so I ended up just using the same numbers as the rest here.
Once we get to 512, we clash with the x32 numbers (unless we remove x32 support first), and probably have to skip a few more. I also considered using the 512..547 space for 32-bit-only calls (which never clash with x32), but that also seems to add a bit of complexity.
I have a patch that I'll send soon to make x32 use its own table. As far as I'm concerned, 547 is *it*. 548 is just a normal number and is not special. But let's please not reuse 512..547 for other purposes on x86 variants -- that way lies even more confusion, IMO.

Fair enough, the space for those numbers is cheap enough here. I take it you mean we also should not reuse that number space if we were to decide to remove x32 soon, but you are not worried about clashing with arch/alpha when everything else uses consistent numbers?

I think we have two issues if we reuse those numbers for new syscalls. First, I'd really like to see new syscalls be numbered consistently everywhere, or at least on all x86 variants, and we can't on x32 because they mean something else. Perhaps more importantly, due to what is arguably a rather severe bug, issuing a native x86_64 syscall (x32 bit clear) with nr in the range 512..547 does *not* return -ENOSYS on a kernel with x32 enabled. Instead it does something that is somewhat arbitrary. With my patch applied, it will return -ENOSYS, but old kernels will still exist, and this will break syscall probing.
Can we perhaps just start the consistent numbers above 547 or maybe block out 512..547 in the new regime?

I'm definitely fine with not reusing them ever, and jumping from 511 to 548 when we get there on all architectures, if you think that helps.
While we could also jump to 548 *now*, I think that would be a bit wasteful. Syscall numbers are fairly cheap, but not entirely free, especially when you consider architectures like mips that have an upper bound of 1000 syscalls before they have to get inventive.

I don't think you gain much with that kind of scheme - it won't take very long before an architecture misses having a syscall added, and then someone else adds their own. Been there with ARM - I was keeping the syscall table in the same order as x86 for new syscalls, but now that others have been adding syscalls to the table since I converted ARM to the tabular form, that's now gone out the window.
So, I think it's completely pointless to do what you're suggesting. We'll just end up with a big hole in the middle of the syscall table and then revert back to random numbering of syscalls thereafter again.

Regardless, I'm wondering what to do with the holes marked "room for arch specific calls". When is a syscall really arch-specific, and can it be added there, and when does it turn out (later) that it isn't, breaking the synchronization again?
The pkey syscalls may be a bad example, as AFAIU they can be implemented on some architectures, but not on some others. Still, I had skipped them when adding new syscalls to m68k.
Perhaps we should get rid of the notion of "arch-specific syscalls", and reserve a slot everywhere anyway?

Yes, that is the idea. This was not realistic before, since each one of the old architectures had its own way of describing the system call tables, and many needed a different set of quirks.
Since (almost) everything is now converted to the syscall.tbl format, we have removed all obsolete architectures, and a lot of the quirks (x32, spu, s390-31) won't matter as much in the future, I think it is now possible to do it.
We could even extend scripts/checksyscalls.sh to warn if a new syscall above 423 is not added to all 16 tables at the same time.
Regardless, I'm wondering what to do with the holes marked "room for arch specific calls". When is a syscall really arch-specific, and can it be added there, and when does it turn out (later) that it isn't, breaking the synchronization again?
We've had a bit of that already, with cacheflush(), which exists on a couple of architectures, including some that use the first 'arch specific' slot (244) of the asm-generic table. I think this will be rare enough that we can figure out a solution when we get there.

I don't mind calling the hole something else if that helps. Out of principle I would already assume that anything we add for x86 or the generic table should be added everywhere, but we can make it broader than that.

Just so I understand: do you mean duplicating the .tbl file, or just the resulting table of entry points?
In either way, how will that work with the new io_uring_setup() system call that will have to use the compat entry point? Are you planning to use the same syscall number as x86_64 but point it to the compat function, or do we still need a new syscall number for x32 in the regular range?

I've successfully tested this with musl and LTP now, using an i386 kernel. The musl port I used is at https://git.linaro.org/people/arnd.bergmann/musl-y2038.git/ This is just an updated version of what I used for testing last year, using the current syscall assignment, and going back to the time32 versions of getitimer/setitimer and wait4/waitid/getusage.
It's certainly not intended for merging like this, but a proper musl port is under discussion now, and this should be sufficient if anyone else wants to try out the new syscall ABI before we merge it.
The LTP I have is heavily hacked, and has a number of failures resulting from differences between musl and glibc, or from the way we convert between the kernel types and the user space types.
The testing found one minor bug in all the kernel syscall tables:
+418 common mq_timedsend_time64 sys_mq_timedsend +419 common mq_timedreceiv_time64 sys_mq_timedreceive
While this would have fit in with umount(), creat() and mknod(), it was unintentional, and I've changed it back to mq_timedreceive_time64 (with an added 'e').

I would be happy to read "Approaching the kernel year-2038 end game" however it is behind a pay wall. Perhaps it may be best to just host interesting articles about open source idea elsewhere.
It's a short summary of the current state. You can also find a video and slides from my ELC presentation online for a little more context.
Generally speaking, I'd recommend paying for the subscription to lwn.net to anyone interested in the kernel, but it should become visible to everyone with the next day (a week after the initial publication). In the meantime, you can find the article at https://lwn.net/SubscriberLink/776435/a59d93d01d1addfc/.
Finally, I've made a list of the remaining work that Deepa and I are planning to still continue (this should be mostly complete but may be missing a few things):
syscalls - merge big series for 5.1, to allow time64 syscalls - waitid/wait4/getrusage should get a replacement based on __kernel_timespec - getitimer/setitimer should probably follow getrusage - vdso, waiting for consolidation series from Vincenzo Frascino before adding time64 entry points
file systems - range checks on timestamps - xfs - NFS - hfs/hfsplus - coda - hostfs - relatime_need_update
drivers - media - alsa - sockets - af_packet - ppp ioctl - rtc ioctl - omap3isp
core kernel - fix ELF core files (elfcore.h) - syscall Audit code (kernel/audit.c, kernel/auditsc.c) - make all time32 code conditional - remove include/linux/timekeeping32.h - remove compat_time* from time32.h - remove timeval - remove timespec - remove time_t

Oh, I pay. Also to FSF and other places however I was merely ranting very very quietly that so much open source is becoming commercialized in so many ways. Sort of expected really.
Pardon my little rant .. I will go back to hacking OpenSSL 1.1.1a and trying to get Apache httpd 2.4.38 release running cleanly.

Hey, this is an unfair characterization: lwn.net operates an early access subscription model, so you can't read the above for 14 days after publication without paying for an lwn.net subscription, but by the time these patches are upstream there will be no paywall because it will expire on 24 January and that URL will then be readable by all. That makes LWN.net a nice, reliable resource for us while still supporting some business model to keep it going.
