08b9cc316a nfscl: Add a VOP_DEALLOCATE() for the NFSv4.2 client
This patch adds a VOP_DEALLOCATE() to the NFS client.
For NFSv4.2 servers that support the Deallocate operation,
it is used. Otherwise, it falls back on calling
vop_stddeallocate().

4e5d32a445 Fix null pointer subtraction in mergesort()
Clang 13 produces the following warning for this function:

lib/libc/stdlib/merge.c:137:41: error: performing pointer subtraction with a null pointer has undefined behavior [-Werror,-Wnull-pointer-subtraction]
        if (!(size % ISIZE) && !(((char *)base - (char *)0) % ISIZE))
                                               ^ ~~~~~~~~~

This is meant to check whether the size and base parameters are aligned
to the size of an int, so use our __is_aligned() macro instead.

Also remove the comment that indicated this "stupid subtraction" was
done to pacify some ancient and unknown Cray compiler, and which has
been there since the BSD 4.4 Lite Lib Sources were imported.

bb958dcf3d nfsd: Add support for the NFSv4.2 Deallocate operation
The recently added VOP_DEALLOCATE(9) VOP call allows
implementation of the Deallocate NFSv4.2 operation.

Since the Deallocate operation is a single succeed/fail
operation, the call to VOP_DEALLOCATE(9) loops so long
as progress is being made.  It calls maybe_yield()
between loop iterations to allow other processes
to preempt it.

Where RFC 7862 underspecifies behaviour, the code
is written to be Linux NFSv4.2 server compatible.

Align passed resource start/end to the set window granularity to keep
it properly aligned.  Currently this is mostly called by other bridges
having the same window alignment, but it may be change one day.

620cf65c2b netinet: prevent NULL pointer dereference in in_aifaddr_ioctl()
It appears that maliciously crafted ifaliasreq can lead to NULL
pointer dereference in in_aifaddr_ioctl(). In order to replicate
that, one needs to

1. Ensure that carp(4) is not loaded

2. Issue SIOCAIFADDR call setting ifra_vhid field of the request
   to a negative value.

A repro code would look like this.

int main() {
    struct ifaliasreq req;
    struct sockaddr_in sin, mask;
    int fd, error;

    bzero(&sin, sizeof(struct sockaddr_in));
    bzero(&mask, sizeof(struct sockaddr_in));

    sin.sin_len = sizeof(struct sockaddr_in);
    sin.sin_family = AF_INET;
    sin.sin_addr.s_addr = inet_addr("192.168.88.2");

    mask.sin_len = sizeof(struct sockaddr_in);
    mask.sin_family = AF_INET;
    mask.sin_addr.s_addr = inet_addr("255.255.255.0");

    fd = socket(AF_INET, SOCK_DGRAM, 0);
    if (fd < 0)
        return (-1);

    memset(&req, 0, sizeof(struct ifaliasreq));
    strlcpy(req.ifra_name, "lo0", sizeof(req.ifra_name));
    memcpy(&req.ifra_addr, &sin, sin.sin_len);
    memcpy(&req.ifra_mask, &mask, mask.sin_len);
    req.ifra_vhid = -1;

    return ioctl(fd, SIOCAIFADDR, (char *)&req);
}

To fix, discard both positive and negative vhid values in
in_aifaddr_ioctl, if carp(4) is not loaded. This prevents NULL pointer
dereference and kernel panic.

lfence after swapgs is needed only for the case when swapgs could be
speculatively executed.  Since syscall entry, unlike exception and
interrupt entries, executes swapgs unconditionally, there is no
opportunity for speculation.
