DARWIN: remove vestigial etap_event_t typedefs
    
    These typedefs have been present since commit
    a41175cfbbf4d06ccfe14ae54bef8b7464ecd80b
    "initial-darwin-support-20010327"; at least some of this material was
    obtained directly from IBM after the initial code import.
    
    Based on research of old Darwin source code and kernel documentation,
    the Event Trace Analysis Package (ETAP) was a lock-profiling interface
    provided in older versions of Mach and xnu.  ETAP was not enabled by
    default; the kernel had to be recompiled with certain options to enable
    it.  Support for ETAP was removed from the xnu tree sometime between
    xnu-517 (10.3 Panther) and xnu-792 (10.4 Tiger), although some
    references remain in the latter under PPC support (osfmk/ppc/hw_lock.s).
    All remaining references to etap_event_t disappeared when PPC support
    was removed, some time between xnu-1456.1.26 (10.6 Snow Leopard) and
    xnu-1699.24.8 (10.7.2 Lion).
    
    Therefore, it is possible that these typedefs were needed in the past by
    (IBM/Transarc) AFS to support use of some lock APIs (e.g.,
    simple_lock_init, usimple_lock_init) after the ETAP code was withdrawn
    from xnu.  However, these typedefs have probably always been vestigial
    for OpenAFS, because OpenAFS has never used any lock API that took
    etap_event_t as an argument.
    
    Regardless, OpenAFS does not need these definitions to build and run on
    any currently supported version of macOS.
    
    Remove the vestigial code.
    
    No functional change should be incurred by this commit.

afs: Handle osi_NewVnode failures
    
    Currently, code inside afs_vcache.c assumes that osi_NewVnode always
    returns non-NULL, which means that osi_NewVnode must panic if it
    cannot create a new vnode.
    
    All of the callers of afs_GetVCache, afs_NewVCache, etc, already
    handle getting a NULL return, though (after all, the given fid may not
    exist or be inaccessible due to network errors, etc). So, just
    propagate NULL returns from osi_NewVnode up to our callers, to avoid
    panics in these situations.
    
    Modify osi_NewVnode on many arches to return an error on allocation
    failure, instead of panic'ing.

rx: remove rx_atomic bitops
    
    The rx_atomic bitops were introduced with commit
    1839cdbe268f4b19ac8e81ae78548f5c78e0c641 ("rx: atomic bit ops").
    
    The last (only) reference to them was recently removed with commit
    5ced6025b9f11fadbdf2e092bf40cc87499ed277 ("rx: Convert rxinit_status to
    rx_IsRunning()").
    
    Remove the now unreferenced bitops.  This commit is comprised of partial
    or complete reverts of the following commits:
    
    ae4ad509d35 rx: fix rx_atomic warnings under Solaris (partial)
    c16423ec4e6 rx: fix atomics on darwin (partial)
    9dc6dd9858a rx: Fix AIX test_and_set_bit (complete)
    1839cdbe268 rx: atomic bit ops (complete)
    
    Note: The rx_atomic bitops for Linux systems are known to be broken due
    to incorrect casting of rx_atomic_t into the unsigned long operand
    expected by the native Linux bitops.  The failure modes include silent
    overruns on little-endian and incorrect results on big-endian.  Do not
    merely revert this commit in order to bring these bitops back into the
    tree.

Linux 5.15: Convert osi_Msg macro to a function
    
    With Linux 5.15-prerc1 printk is defined as a macro instead of a
    function ("printk: Userspace format indexing support" 33701557)
    
    This change is causing a build failure:
    
     .../src/rx/rx_kernel.h:62:18: error: ‘printk’ undeclared (first use in
       this function); did you mean ‘_printk’?
       62 | # define osi_Msg printk)(
          |                  ^~~~~~
    
    The definition and use of the osi_Msg and osi_VMsg macros are
    unconventional and the C preprocessor is not handling the macro
    expansion when printk is itself a macro.
    
       #define osi_Msg printk)(
       ...
       (osi_Msg "%s", x);
    
    Change osi_Msg to a function, and simply replace osi_VMsg with vprintf
    since osi_VMsg is only used at one location within user space code.
    
    osi_Msg is implemented in 2 locations, in rx_kcommon for kernel space
    and in rx_user for userspace.
    
    Note: The unconventional definitions of osi_Msg/osi_VMsg was historical
    and due to older compilers not supporting variadic macros.  All of
    the currently support platforms should now support variadic functions.

LINUX 5.14: explicitly set set_page_dirty to default
    
    Linux 5.14 commit: 'mm: require ->set_page_dirty to be explicitly wired
    up' (0af573780b0b13) removed calling __set_page_dirty_buffers when the
    address_space_operations structure member set_page_dirty was NULL.
    
    A kernel RIP error can occur when the set_page_dirty operation is
    requested. (Reproducible by running 'iozone -B -a')
    
    Update the definition for afs_file_aops to explicitly set the
    'set_page_dirty' member to '__set_page_dirty_buffers'.
    
    There are no functional changes, since this commit is using the same
    function that the Linux kernel was using if set_page_dirty had been
    NULL.
    
    Problem originally reported by "Andrej Filipcic"
    <andrej.filipcic@ijs.si> in the openafs-info mailing list.  The Linux
    5.14 commit causing the openafs failure was identified by "Michael Laß"
    <lass@mail.upb.de> also on in the openafs-info mailing list.
    
    Note: The declaration for the function '__set_page_dirty_buffers' was
    moved from linux/mm.h into linux/buffer_head.h in Linux 2.6.19.  Since
    this is close to the minimum supported Linux version 2.6.18, we are not
    introducing an additional autoconf test to determine which header file
    the declaration for __set_page_dirty_buffers resides in.

rx: Reorganize LWP rxi_Sendmsg to use 'goto error'
    
    Our LWP version of rxi_Sendmsg can allocate an fd_set, but we don't
    free the fd_set if sendmsg() returns certain errors afterwards.
    
    To make sure we go through the same cleanup code for the different
    possible error code paths, reorganize the function to go through a
    'goto error'-style destructor. This also makes our return codes a bit
    more consistent; we should always return -errno now for errors.

FBSD: avoid vrefl()
    
    Commit 20dc2832268eb (correctly) introduced changes so that we
    avoid interacting with vnodes marked as VI_DOOMED to the extent
    possible, but in doing so inadvertendly used the vrefl() KPI that
    was only introduced in FreeBSD 11.0.
    
    Rewrite the relevant logic to use the older vref() KPI, at the cost
    of a few more unlock/locks, in order to have a single codepath that
    works on all supported FreeBSD versions.

FBSD: Ignore VI_DOOMED vnodes
    
    Currently on FreeBSD, osi_TryEvictVCache calls vgone() for our vnode
    after checking if the given vcache is in use. vgone() then calls our
    VOP_RECLAIM operation, which calls afs_vop_reclaim, which calls
    afs_FlushVCache to finally actually flush the vcache.
    
    The current approach has at least the following major issues:
    
    - In afs_vop_reclaim, we return success even if afs_FlushVCache()
      fails. This allows FreeBSD to reuse the vnode for another file, but
      the vnode is still being referenced by our vcache, which is
      referenced by the global VLRU and various other structures. This
      causes all kinds of weird errors, since we try to use the underlying
      vnode for different files.
    
    - After the relevant checks in osi_TryEvictVCache are done, another
      thread can acquire a new reference to our vcache (this can happen
      while vgone() is running up until the vnode is locked). This new
      reference will cause afs_FlushVCache to fail.
    
    - Our afs_vop_reclaim callback is called while the vnode is locked,
      and can acquire afs_xvcache. Other code locks the vnode while
      afs_xvcache is already held (such as afs_PutVCache -> vrele). This
      can lead to deadlocks if two threads try to run these codepaths for
      the same vnode at the same time.
    
    - afs_vop_reclaim optionally acquires afs_xvcache based on the return
      value of CheckLock(&afs_xvcache). However, CheckLock just returns if
      that lock is locked by anyone, not if the current thread holds the
      lock. This can result in the rest of the function running without
      afs_xvcache actually being held if we drop AFS_GLOCK at any point.
    
    - osi_TryEvictVCache() tries to vn_lock() the target vnode, but we may
      already have another vnode locked in the current thread. If the
      vnode we're trying to evict is a descendant of a vnode we already
      have locked, this can deadlock.
    
    To fix these issues, make some changes to how our vcache management
    works on FreeBSD:
    
    - Do not allow anyone to hold a new reference on a VI_DOOMED vnode.
      We do this by checking for VI_DOOMED in osi_vnhold, and returning an
      error if VI_DOOMED is set.
    
    - In afs_vop_reclaim, panic if afs_FlushVCache fails. With the new
      VI_DOOMED check, afs_FlushVCache show now never fail; and if it
      somehow does, panic'ing immediately is better than corrupting
      various structures and panic'ing later on.
    
    - Move around some of the relevant locking in afs_vop_reclaim to fix
      the lock-related issues.
    
    - In osi_TryEvictVCache, don't wait for the vnode lock (LK_NOWAIT);
      treat the vnode as "in use" if we can't immediately obtain the lock.
    
    Thanks to tcreech@tcreech.com and kaduk@mit.edu for insight and help
    investigating the relevant issues.

afs: Refactor osi_vnhold/AFS_FAST_HOLD
    
    Make a few changes to osi_vnhold and AFS_FAST_HOLD:
    
    - Currently, the second argument of osi_vnhold ("retry") is never used
      by any implementation. Get rid of it.
    
    - AFS_FAST_HOLD() is the same as osi_vnhold(). Get rid of
      AFS_FAST_HOLD, and just have all callers use osi_vnhold instead.
    
    - Allow osi_vnhold to return an error, and adjust callers to handle
      it.
    
    - Change osi_vnhold to be a real function, instead of a macro, to make
      nontrivial implementations less cumbersome.
    
    Most platforms never return an error from osi_vnhold(), so the added
    code paths to check the return value of osi_vnhold() will not trigger.
    However, this lets us add future commits that do make osi_vnhold()
    return an error.

FBSD: Avoid holding AFS_GLOCK during vinvalbuf
    
    Currently we call vinvalbuf(9) in a few places while holding
    AFS_GLOCK, but AFS_GLOCK is a non-sleepable lock (struct mtx), and
    vinvalbuf can sleep. This can trigger a panic in some rare conditions,
    with the message:
    
        Sleeping thread (tid 100179, pid 95481) owns a non-sleepable lock
    
    To avoid this, drop AFS_GLOCK around a few places that call
    vinvalbuf().

FBSD: Add proper locks when traversing net ifaces
    
    When traversing the list of network interfaces, or the list of
    addresses for a network interface, we're supposed to lock the relevant
    resource with IFNET_RLOCK, if_addr_rlock, or IN_IFADDR_RLOCK. Add
    these locks around our code that examines network interfaces, to
    avoid issues if the interface or address list changes while we're
    traversing them.
    
    While we're doing this, move around some "AFS_DARWIN_ENV ||
    AFS_FBSD_ENV" ifdefs, since these were getting a bit hard to read.
    This commit adds some duplicated code, but the result should be easier
    to follow.
    
    Also for FreeBSD 12, we must be in NET_EPOCH_ENTER when calling
    ifa_ifwithnet/rx_ifaddr_withnet (it panics if we don't, with
    INVARIANTS). Add the needed NET_EPOCH_ENTER/EXIT calls, but do so a
    bit higher up the call stack, since the returned structures are
    potentially no longer valid after we NET_EPOCH_EXIT. Since this means
    we're calling these in a few places in libafs, create a couple of rx
    abstractions (RX_NET_EPOCH_ENTER) to handle the relevant ifdefs.

    DARWIN/FBSD ifdefs.]

    haven't been supported by FreeBSD itself for a while.
    
    FreeBSD 10.x EoL was on October 31, 2018, which has passed, but was
    less than a year ago. So keep 10.x in for now.
    
    Adjust our preprocessor checks accordingly:
    
    - In FBSD-specific dirs, assume AFS_FBSD100_ENV and lower is always
      true. Assume __FreeBSD_version is always at least 1000000.
    
    - In non-FBSD dirs, convert AFS_FBSD100_ENV and lower to AFS_FBSD_ENV.

FBSD: Handle malloc/free changes in FBSD 12
    
    FreeBSD 12 (r328417) removed the deprecated compatibility macros
    MALLOC and FREE. Convert our users to just use the normal malloc and
    free, so we can build.
    
    FreeBSD 12 (r334545) also changed malloc() into a macro, which breaks
    our own malloc macro in our hcrypto config.h. To fix this, just undef
    malloc, if it's already a macro.

commit 29f30ed16c6db544f020142c11c4296227eebf99

rx: compare RX_ACK_TYPE_ACK as a bit-field
    
    The rx_ackPacket.acks array (the SACK table) consists of up to 255
    octets.  Each octet stores either the value zero (RX_ACK_TYPE_NACK)
    or one (RX_ACK_TYPE_ACK).  Effectively only bit-zero of each octet
    is used.
    
    The rx_ackPacket.acks array cannot be enlarged but one possible
    method of encoding the ACK/NACK state for packets when the
    window size is greater than 255 is to use bits 1-7 of each
    octet.
    
    This change alters the test for ACK vs NACK to be a bit comparison
    instead of a equality comparison.  This change permits RX to be
    compatible with any future use of bits 1-7.
    
    No peer that treats the SACK table as bytes can ever send more
    than 255 packets regardless of the advertised receive window.
    Therefore, existing peers will never receive a SACK table with
    more than 255 packets worth of bits.
