0abd386d8b docs/system/target-avr: Improve the AVR docs and add to MAINTAINERS
The examples look nicer when using "::" code blocks.
Also mention that "-d in_asm" only outputs instructions that have not
been translated by the JIT layer yet.
And while we're at it, also add the AVR doc file to the MAINTAINERS file.

28b18db754 hw/isa/isa-superio: Fix IDE controller realization
When realizing a Super I/O with IDE controller [*], we get:

  qom/object.c:1684: object_property_try_add_child: Assertion `!child->parent' failed.
  Aborted (core dumped)

This is because the device is already realized when we try to
add the QOM property to the parent. Fix by realizing *after*
adding the QOM relationship.

[*] Set ISASuperIOClass::ide.count = N with N not zero
    (no such thing currently exists; the bug is latent)

cac46eb021 linux-user: Add support for utimensat_time64() and semtimedop_time64()
This patch introduces functionality for following time64 syscalls:

*utimensat_time64()

    int utimensat(int dirfd, const char *pathname,
                  const struct timespec times[2], int flags);
    -- change file timestamps with nanosecond precision --
    man page: https://man7.org/linux/man-pages/man2/utimensat.2.html

*semtimedop_time64()

    int semtimedop(int semid, struct sembuf *sops, size_t nsops,
                   const struct timespec *timeout);
    -- System V semaphore operations --
    man page: https://www.man7.org/linux/man-pages/man2/semtimedop.2.html

Implementation notes:

   Syscall 'utimensat_time64()' is implemented in similar way as its
   regular variants only difference being that time64 converting function
   is used to convert values of 'struct timespec' between host and target
   ('target_to_host_timespec64()').

   For syscall 'semtimedop_time64()' and additional argument is added
   in function 'do_semtimedop()' through which the aproppriate 'struct timespec'
   converting function is called (false for regular target_to_host_timespec()
   and true for target_to_host_timespec64()). For 'do_ipc()' a
   check was added as that additional argument: 'TARGET_ABI_BITS == 64'.

ddcbde157d linux-user: Add support for 'rt_sigtimedwait_time64()' and 'sched_rr_get_interval_time64()'
This patch implements functionality for following time64 syscalls:

*rt_sigtimedwait_time64()

    This is a year 2038 safe variant of syscall:

    int rt_sigtimedwait(const sigset_t *set, siginfo_t *info,
                        const struct timespec *timeout, size_t sigsetsize)
    --synchronously wait for queued signals--
    man page: https://man7.org/linux/man-pages/man2/rt_sigtimedwait.2.html

*sched_rr_get_interval_time64()

    This is a year 2038 safe variant of syscall:

    int sched_rr_get_interval(pid_t pid, struct timespec *tp)
    --get  the  SCHED_RR  interval  for the named process--
    man page: https://man7.org/linux/man-pages/man2/sched_rr_get_interval.2.html

Implementation notes:

    These syscalls were implemented in similar ways like
    'rt_sigtimedwait()' and 'sched_rr_get_interval()' except
    that functions 'target_to_host_timespec64()' and
    'host_to_target_timespec64()' were used to convert values
    of 'struct timespec' between host and target.

6ac03b2cac linux-user: Add support for 'clock_nanosleep_time64()' and 'clock_adjtime64()'
This patch implements functionality for following time64 syscall:

*clock_nanosleep_time64()

    This is a year 2038 safe vairant of syscall:
    int clock_nanosleep(clockid_t clockid, int flags,
                        const struct timespec *request,
                        struct timespec *remain)
    --high-resolution sleep with specifiable clock--
    man page: https://man7.org/linux/man-pages/man2/clock_nanosleep.2.html

*clock_adjtime64()

    This is a year 2038 safe variant of syscall:
    int clock_adjtime(clockid_t clk_id, struct timex *buf)
    --tune kernel clock--
    man page: https://man7.org/linux/man-pages/man2/clock_adjtime.2.html

Implementation notes:

    Syscall 'clock_nanosleep_time64()' was implemented similarly
    to syscall 'clock_nanosleep()' except that 'host_to_target_timespec64()'
    and 'target_to_host_timespec64()' were used instead of the regular
    'host_to_target_timespec()' and 'target_to_host_timespec()'.

    For 'clock_adjtime64()' a 64-bit target kernel version of 'struct timex'
    was defined in 'syscall_defs.h': 'struct target__kernel_timex'.
    This type was used to convert the values of 64-bit timex type between
    host and target. For this purpose a 64-bit timex converting functions
    'target_to_host_timex64()' and 'host_to_target_timex64()'. An existing
    function 'copy_to_user_timeval64()' was used to convert the field
    'time' which if of type 'struct timeval' from host to target.
    Function 'copy_from_user_timveal64()' was added in this patch and
    used to convert the 'time' field from target to host.

fd9279ec99 virtiofsd: probe unshare(CLONE_FS) and print an error
An assertion failure is raised during request processing if
unshare(CLONE_FS) fails. Implement a probe at startup so the problem can
be detected right away.

Unfortunately Docker/Moby does not include unshare in the seccomp.json
list unless CAP_SYS_ADMIN is given. Other seccomp.json lists always
include unshare (e.g. podman is unaffected):
https://raw.githubusercontent.com/seccomp/containers-golang/master/seccomp.json

Use "docker run --security-opt seccomp=path/to/seccomp.json ..." if the
default seccomp.json is missing unshare.

1c7cb1f52e virtiofsd: drop CAP_DAC_READ_SEARCH
virtiofsd does not need CAP_DAC_READ_SEARCH because it already has
the more powerful CAP_DAC_OVERRIDE. Drop it from the list of
capabilities.

This is important because container runtimes may not include
CAP_DAC_READ_SEARCH by default. This patch allows virtiofsd to reduce
its capabilities when running inside a Docker container.

Note that CAP_DAC_READ_SEARCH may be necessary again in the future if
virtiofsd starts using open_by_handle_at(2).

88fc107956 virtiofsd: Disable remote posix locks by default
Right now we enable remote posix locks by default. That means when guest
does a posix lock it sends request to server (virtiofsd). But currently
we only support non-blocking posix lock and return -EOPNOTSUPP for
blocking version.

This means that existing applications which are doing blocking posix
locks get -EOPNOTSUPP and fail. To avoid this, people have been
running virtiosd with option "-o no_posix_lock". For new users it
is still a surprise and trial and error takes them to this option.

Given posix lock implementation is not complete in virtiofsd, disable
it by default. This means that posix locks will work with-in applications
in a guest but not across guests. Anyway we don't support sharing
filesystem among different guests yet in virtiofs so this should
not lead to any kind of surprise or regression and will make life
little easier for virtiofs users.

a9e80a5f0c migration: tls: fix memory leak in migration_tls_get_creds
Currently migration_tls_get_creds() adds the reference of creds
but there was no place to unref it.  So the OBJECT(creds) will
never be freed and result in memory leak.

The leak stack:
Direct leak of 104 byte(s) in 1 object(s) allocated from:
    #0 0xffffa88bd20b in __interceptor_malloc (/usr/lib64/libasan.so.4+0xd320b)

Since we're fine to use the borrowed reference when using the creds,
so just remove the object_ref() in migration_tls_get_creds().
