| Pull exec/proc updates from Eric Biederman: "This contains two significant pieces of work: the work to sort out proc_flush_task, and the work to solve a deadlock between strace and exec. Fixing proc_flush_task so that it no longer requires a persistent mount makes improvements to proc possible. The removal of the persistent mount solves an old regression that that caused the hidepid mount option to only work on remount not on mount. The regression was found and reported by the Android folks. This further allows Alexey Gladkov's work making proc mount options specific to an individual mount of proc to move forward. The work on exec starts solving a long standing issue with exec that it takes mutexes of blocking userspace applications, which makes exec extremely deadlock prone. For the moment this adds a second mutex with a narrower scope that handles all of the easy cases. Which makes the tricky cases easy to spot. With a little luck the code to solve those deadlocks will be ready by next merge window" * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (25 commits) signal: Extend exec_id to 64bits pidfd: Use new infrastructure to fix deadlocks in execve perf: Use new infrastructure to fix deadlocks in execve proc: io_accounting: Use new infrastructure to fix deadlocks in execve proc: Use new infrastructure to fix deadlocks in execve kernel/kcmp.c: Use new infrastructure to fix deadlocks in execve kernel: doc: remove outdated comment cred.c mm: docs: Fix a comment in process_vm_rw_core selftests/ptrace: add test cases for dead-locks exec: Fix a deadlock in strace exec: Add exec_update_mutex to replace cred_guard_mutex exec: Move exec_mmap right after de_thread in flush_old_exec exec: Move cleanup of posix timers on exec out of de_thread exec: Factor unshare_sighand out of de_thread and call it separately exec: Only compute current once in flush_old_exec pid: Improve the comment about waiting in zap_pid_ns_processes proc: Remove the now unnecessary internal mount of proc uml: Create a private mount of proc for mconsole uml: Don't consult current to find the proc_mnt in mconsole_proc proc: Use a list of inodes to flush from proc ... | |||||

| 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. 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" [1] https://git.kernel.org/pub/scm/linux/kernel/git/arnd/playground.git/log/?h=y2038-endgame * tag 'y2038-drivers-for-v5.6-signed' of git://git.kernel.org:/pub/scm/linux/kernel/git/arnd/playground: (21 commits) Revert "drm/etnaviv: reject timeouts with tv_nsec >= NSEC_PER_SEC" y2038: sh: remove timeval/timespec usage from headers y2038: sparc: remove use of struct timex y2038: rename itimerval to __kernel_old_itimerval y2038: remove obsolete jiffies conversion functions nfs: fscache: use timespec64 in inode auxdata nfs: fix timstamp debug prints nfs: use time64_t internally sunrpc: convert to time64_t for expiry drm/etnaviv: avoid deprecated timespec drm/etnaviv: reject timeouts with tv_nsec >= NSEC_PER_SEC drm/msm: avoid using 'timespec' hfs/hfsplus: use 64-bit inode timestamps hostfs: pass 64-bit timestamps to/from user space packet: clarify timestamp overflow tsacct: add 64-bit btime field acct: stop using get_seconds() um: ubd: use 64-bit time_t where possible xtensa: ISS: avoid struct timeval dlm: use SO_SNDTIMEO_NEW instead of SO_SNDTIMEO_OLD ... | |||||

| 2020-01-19 | um: Mark non-vector net transports as obsolete | Brendan Higgins | 1 | -40/+41 | |
| 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.

| 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.

| 2019-12-18 | um: ubd: use 64-bit time_t where possible | Arnd Bergmann | 3 | -9/+10 | |
| 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.

| Pull removal of most of fs/compat_ioctl.c from Arnd Bergmann: "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.

| 2019-11-25 | um: Loadable BPF "Firmware" for vector drivers |   Anton Ivanov | 4 | -30/+193 | |
| 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> | |||||

| 2019-11-25 | um: virtio: Keep reading on -EAGAIN | Johannes Berg | 1 | -4/+4 | |
| 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 only in the startup phase. With the inband call feature this does tend to happen (eventually) though. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Richard Weinberger <richard@nod.at> | |||||

| 2019-10-23 | compat_ioctl: move WDIOC handling into wdt drivers | Arnd Bergmann | 1 | -0/+1 | |
| 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.

| 2019-10-23 | compat_ioctl: remove translation for sound ioctls | Arnd Bergmann | 1 | -0/+1 | |
| 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> | |||||

One can also recheck/review the patch via generating it with explanation comments included via $ make coccicheck MODE=patch COCCI=scripts/coccinelle/api/stream_open.cocci SPFLAGS="-D explain" (*) This second group also contains cases with read/write deadlocks that stream_open.cocci don't yet detect, but which are still valid to convert to stream_open since ppos is not used. For example drivers/pci/switch/switchtec.c calls wait_for_completion_interruptible() in its .read, but stream_open.cocci currently detects only "wait_event*" as blocking.
