y2038: core, driver and file system changes
These are updates to device drivers and file systems that for some reason or another were not included in the kernel in the previous y2038 series. I've gone through all users of time_t again to make sure the kernel is in a long-term maintainable state, replacing all remaining references to time_t with safe alternatives. Some related parts of the series were picked up into the nfsd, xfs, alsa and v4l2 trees. A final set of patches in linux-mm removes the now unused time_t/timeval/timespec types and helper functions after all five branches are merged for linux-5.6, ensuring that no new users get merged. As a result, linux-5.6, or my backport of the patches to 5.4 [1], should be the first release that can serve as a base for a 32-bit system designed to run beyond year 2038, with a few remaining caveats: - All user space must be compiled with a 64-bit time_t, which will be supported in the coming musl-1.2 and glibc-2.32 releases, along with installed kernel headers from linux-5.6 or higher. - Applications that use the system call interfaces directly need to be ported to use the time64 syscalls added in linux-5.1 in place of the existing system calls. This impacts most users of futex() and seccomp() as well as programming languages that have their own runtime environment not based on libc. - Applications that use a private copy of kernel uapi header files or their contents may need to update to the linux-5.6 version, in particular for sound/asound.h, xfs/xfs_fs.h, linux/input.h, linux/elfcore.h, linux/sockios.h, linux/timex.h and linux/can/bcm.h. - A few remaining interfaces cannot be changed to pass a 64-bit time_t in a compatible way, so they must be configured to use CLOCK_MONOTONIC times or (with a y2106 problem) unsigned 32-bit timestamps. Most importantly this impacts all users of 'struct input_event'. - All y2038 problems that are present on 64-bit machines also apply to 32-bit machines. In particular this affects file systems with on-disk timestamps using signed 32-bit seconds: ext4 with ext3-style small inodes, ext2, xfs (to be fixed soon) and ufs. Changes since v1 [2]: - Add Acks I received - Rebase to v5.5-rc1, dropping patches that got merged already - Add NFS, XFS and the final three patches from another series - Rewrite etnaviv patches - Add one late revert to avoid an etnaviv regression [1] https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git/log/?h=y2038-endgame [2] https://lore.kernel.org/lkml/20191108213257.3097633-1-arnd@arndb.de/ -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJeMYy3AAoJEGCrR//JCVInEGwP/0R+S+ok7vw9OdLVT0lFl07D IcVabgOWf24imN7m7L7Mlt3nDfxIT4tMpiAXq7eMO3spcyViG18O2LXdSQ4/7QBp +BlhoMjOP9w34Jyd7mnkFr4vqQALvfIqkS8rFObDtDub2Rfj9PC36MRMIu8BPXlv RK8bigwJeH/DV38yc5/JeUcD+WuewYLsK9XPWN+4yB4vgGsNU3ZQQ6nnzbR3hMsN DN8WZ68Y7IBs0Kyxkf+s2zmRXtCa2RiFg/2TUsk5olVAJVaenvte69hq5RSbg1vW vLi6K8cBoPWL59nqCzcNE+TUhSUg3LOj/a/KWyl76yovz7AlJaNjssOf8ZjHw6sL MhQqz3hXTxiJDS2Jvbf1yojiYGlzrq/gqcRFGe9jPcZdieMc4/yZCx60G/Exa5Pu YdMcqMyDWPFyUAFQNWEF59HPheOdj6tb1KpJ6bwgCo3P7QqhLrU4z9w3Py4/ZfBO 4sWcWteSsD6MN/ADJ2WQ56nNxzM2AvkeVJKcF6FCkdngXX9T0GExmZz7SqB5Du99 9lNjIiD5E+LBa/Swo/7n49aYa8x06V1pmHYTZVh9Wkl+CZiO21umezQFrWsfaMTp xt3c6pFdMG5xNMGpreTAXOmf2R+T6O8IO2qQq/TYjzqOLH7QC830P7avkmml+cK1 LjOBE2TfSeO8Ru1dXV4t =wx0A -----END PGP SIGNATURE----- Merge tag 'y2038-drivers-for-v5.6-signed' of git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground Pull y2038 updates from Arnd Bergmann: "Core, driver and file system changes These are updates to device drivers and file systems that for some reason or another were not included in the kernel in the previous y2038 series.

um: Mark non-vector net transports as obsolete
UML_NET_VECTOR now supports filters compiled with pcap outside of UML; it also supports: EoGRE, EoL2TPv3, RAW (+/- BPF), TAP and BESS. While vector drivers are not 1:1 replacements for the existing drivers, you can achieve the same topologies and the same connectivity at much higher performance (2.5 to 9 Gbit on mid-range Ryzen desktop) - the old drivers test out in the 500Mbit range on the same hardware. For all these reasons, the non-vector based transports are now unnecessary, and some, most notably pcap and vde are maintenance burdens. Thus, it makes sense to at least start thinking about removing the non-vector transports, so for now, mark them as obsolete.

um: Add an option to make serial driver non-raw
In some cases, for example when the program(s) running inside UML isn't/aren't interactive (like the hwsim tests for wpa_supplicant) there's really no value in having the serial lines configured to be raw as they are now by default. Setting them to non-raw lets one abort the whole UML with Ctrl-C, which is really the right thing to do in these cases, basically the whole UML instance is more like a single (testing) program. Add a "ssl-non-raw" option to UML to support such a mode. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Richard Weinberger <richard@nod.at> |

compat_ioctl: ubd, aoe: use blkdev_compat_ptr_ioctl
These drivers implement the HDIO_GET_IDENTITY and CDROMVOLREAD ioctl commands, which are compatible between 32-bit and 64-bit user space and traditionally handled by compat_blkdev_driver_ioctl(). As a prerequisite to removing that function, make both drivers use blkdev_compat_ptr_ioctl() as their .compat_ioctl callback.

um: ubd: use 64-bit time_t where possible
The ubd code suffers from a possible y2038 overflow on 32-bit architectures, both for the cow header and the os_file_modtime() function. Replace time_t with time64_t to extend the ubd_kern side as much as possible. Whether this makes a difference for the user side depends on the host libc implementation that may use either 32-bit or 64-bit time_t. For the cow file format, the header contains an unsigned 32-bit timestamp, which is good until y2106, passing this through a 'long long' gives us a consistent interpretation between 32-bit and 64-bit um kernels.

netdev: pass the stuck queue to the timeout handler
This allows incrementing the correct timeout statistic without any mess.
Down the road, devices can learn to reset just the specific queue.

compat_ioctl: remove most of fs/compat_ioctl.c
As part of the cleanup of some remaining y2038 issues, I came to fs/compat_ioctl.c, which still has a couple of commands that need support for time64_t. In completely unrelated work, I spent time on cleaning up parts of this file in the past, moving things out into drivers instead. After Al Viro reviewed an earlier version of this series and did a lot more of that cleanup, I decided to try to completely eliminate the rest of it and move it all into drivers. This series incorporates some of Al's work and many patches of my own, but in the end stops short of actually removing the last part, which is the scsi ioctl handlers. I have patches for those as well, but they need more testing or possibly a rewrite.

um: Loadable BPF "Firmware" for vector drivers
All vector drivers now allow a BPF program to be loaded and associated with the RX socket in the host kernel. 1. The program can be loaded as an extra kernel command line option to any of the vector drivers. 2. The program can also be loaded as "firmware", using the ethtool flash option. It is possible to turn this facility on or off using a command line option. A simplistic wrapper for generating the BPF firmware for the raw socket driver out of a tcpdump/libpcap filter expression can be found at: https://github.com/kot-begemot-uk/uml_vector_utilities/ Signed-off-by: Anton Ivanov <anton.ivanov@cambridgegreys.com> Signed-off-by: Richard Weinberger <richard@nod.at> |

um: virtio_uml: Disallow modular build
This driver *can* be a module, but then its parameters (socket path)
are untrusted data from inside the VM, and that isn't allowed. Allow
the code to only be built-in to avoid that.
Fixes:

um: virtio: Keep reading on -EAGAIN
When we get an interrupt from the socket getting readable,
and start reading, there's a possibility for a race. This
depends on the implementation of the device, but e.g. with
qemu's libvhost-user, we can see:
device virtio_uml
---------------------------------------
write header
get interrupt
read header
read body -> returns -EAGAIN
write body
The -EAGAIN return is because the socket is non-blocking,
and then this leads us to abandon this message.
In fact, we've already read the header, so when the get
another signal/interrupt for the body, we again read it
as though it's a new message header, and also abandon it
for the same reason (wrong size etc.)
This essentially breaks things, and if that message was
one that required a response, it leads to a deadlock as
the device is waiting for the response but we'll never
reply.
Fix this by spinning on -EAGAIN as well when we read the
message body. We need to handle -EAGAIN as "no message"
while reading the header, since we share an interrupt.
Note that this situation is highly unlikely to occur in
normal usage, since there will be very few messages and

compat_ioctl: move WDIOC handling into wdt drivers
All watchdog drivers implement the same set of ioctl commands, and fortunately all of them are compatible between 32-bit and 64-bit architectures. Modern drivers always go through drivers/watchdog/wdt.c as an abstraction layer, but older ones implement their own file_operations on a character device for this. Move the handling from fs/compat_ioctl.c into the individual drivers. Note that most of the legacy drivers will never be used on 64-bit hardware, because they are for an old 32-bit SoC implementation, but doing them all at once is safer than trying to guess which ones do or do not need the compat_ioctl handling.

compat_ioctl: remove translation for sound ioctls
The SNDCTL_* and SOUND_* commands are the old OSS user interface. I checked all the sound ioctl commands listed in fs/compat_ioctl.c to see if we still need the translation handlers. Here is what I found: - sound/oss/ is (almost) gone from the kernel, this is what actually needed all the translations - The ALSA emulation for OSS correctly handles all compat_ioctl commands already. - sound/oss/dmasound/ is the last holdout of the original OSS code, this is only used on arch/m68k, which has no 64-bit mode and hence needs no compat handlers - arch/um/drivers/hostaudio_kern.c may run in 64-bit mode with 32-bit x86 user space underneath it. This rare corner case is the only one that still needs the compat handlers. By adding a simple redirect of .compat_ioctl to .unlocked_ioctl in the UML driver, we can remove all the COMPATIBLE_IOCTL() annotations without a change in functionality. For completeness, I'm adding the same thing to the dmasound file, knowing that it makes no difference. The compat_ioctl list contains one comment about SNDCTL_DSP_MAPINBUF and SNDCTL_DSP_MAPOUTBUF, which actually would need a translation handler if implemented. However, the native implementation just returns -EINVAL, so we don't care. Reviewed-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Arnd Bergmann <arnd@arndb.de> |

um: Error handling fixes in vector drivers
With the addition of bess support which uses connection oriented SEQPACKET sockets the vector routines can now encounter a "remote end closed the connection" scenario. This adds handling code to detect it in the TX path and the legacy RX path. There is no way to detect it in the vector RX path because that can legitimately return 0 even if the remote end has not closed the connection. As a result the detection is delayed until the first TX event after the close. Signed-off-by: Anton Ivanov <anton.ivanov@cambridgegreys.com> Signed-off-by: Richard Weinberger <richard@nod.at> |

um: Fix IRQ controller regression on console read
The conversion of UML to use epoll based IRQ controller claimed that
clone_one_chan() can safely call um_free_irq() while starting to ignore
the delay_free_irq parameter that explicitly noted that the IRQ cannot
be freed because this is being called from chan_interrupt(). This
resulted in free_irq() getting called in interrupt context ("Trying to
free IRQ 6 from IRQ context!").
Fix this by restoring previously used delay_free_irq processing.
