String value enforcement broke a number of tests
where we use different values.
Be more string as to what string values we use in tests.
Required to add tmpfs descriptions to test syz_mount_image.
Also special-casing AF_ALG algorithms as these are auto-generated.

Strings with enumerated values are frequently file names
or have complete enumeration of relevant values.
Mutating complete enumeration if not very profitable.
Mutating file names leads to escaping paths and
fuzzer messing with things it is not supposed to mess with as in:
r0 = openat$apparmor_task_exec(0xffffffffffffff9c, &(0x7f0000000440)='/proc/self//exe\x00', 0x3, 0x0)

Mark ifindex as opt in SIOCGIFINDEX.
Otherwise it's considered inout and SIOCGIFINDEX can't be used
to produce ifindex'es on its own. It requires an input ifindex
first and only then it can output own ifindex.

virt_wifi docs say that the enslaved device won't be usable
on itself. It's probably not a good idea to make lo unusable.
Enslave a dedicated veth instead.

1. Use optional[T] instead of array[T, 0:1].
2. Deduplicate 3 copies of ARP packet.
3. Deduplicate IPOPT_LSRR/IPOPT_SSRR/IPOPT_RR.
4. More precise description of IPOPT_TIMESTAMP/IPOPT_LSRR/IPOPT_SSRR/IPOPT_RR.
5. Don't use IPOPT_END/IPOPT_NOOP in generic option (they have different format).
6. Restrict cipso doi values.
7. Fix IPOPT_RA value type (int16 instead of int32).
8. Match ipv4/ipv6 packet type with payload.
9. Prefer 0 frag_off for ipv4 packets (they are extremely hard to get right).

Lots of interesting findings...

Turns out int64 alignment is 4 on 386...
But on arm it's still 8.
Another amusing finding thanks to syz-check.

We get them in cross-compilation test where an out const
arg has different values in different archs.
No reason to fail deserialization in that case, replace with default
arg instead.

We used size as alignment, this is very wrong.

Just trying to get my head around it (and fix this in tests).

All callers of BitfieldMiddle just want static size (0 for middle).
Make it so: Size for middle bitfields just returns 0. Removes lots of if's.
Introduce Type.UnitSize, which now holds the underlying type for bitfields.
This will be needed to fix #1542 b/c even if UnitSize=4 for last bitfield
Size can be anywhere from 0 to 4 (not necessary equal to UnitSize due to overlapping).

We assumed that for ConstType alignment is equal to size,
which is perfectly reasonable for normal int8/16/32/64/ptr.
However, padding is also represented by ConstType of arbitrary size,
so if we added 157 bytes of padding that becomes alignment of
the padding field and as the result of the whole struct.
This affects very few structs, but quite radically and quite
important structs.
Discovered thanks to syz-check.

Fix some descirptions disperancies with kernel and regenerate warnings on next-20191218.

Some sounds ioctls are now explicitly doubled for 32/64 bits. Support that.
Fix mips SOL_SOCKET issues by rearranging includes.
Improve few other fields.
|

|

Regenerate on next-20191217.
Rename s/VMADDR_CID_RESERVED/VMADDR_CID_LOCAL/ as it was renamed in kernel.

This patch adds all autogenerated files for linux/mips64le. Files are
generated by following commands:
make extract
bin/syz-extract -build -os=linux -arch=mips64le -sourcedir=linux
make generate

2. Define bits of bmNetworkCapabilities.

Add tests for issue #1542
The correct results are obtained with the following program:
struct foo {
unsigned char f0;
unsigned int f1:4;
unsigned short f2:4;
};
struct bar {
char f0;
struct foo foo;
};
int main() {
struct bar y;
memset(&y, 0, sizeof(y));
y.f0 = 0x12;
y.foo.f0 = 0x34;
y.foo.f1 = 0x56;
y.foo.f2 = 0x78;
int i;
for (i = 0; i < sizeof(y); i++)
printf("%02x", ((unsigned char*)&y)[i]);
printf("\n");
}

Enable /dev/tty{1-6}. These seem to be special.
Few first connected to framebuffers. But the rest
seem to be different from e.g. tty20 anyway.
Also /dev/tty is different from the rest.
/dev/ttyS3 and /dev/ttyprintk are different.
Properly pair BSD pty terminals.

qemu -vga cirrus results in /dev/fb0 and /dev/fb1.

Framebuffer descriptions + open more tty dev nodes.

Regenerate consts now that make extract is fixed.
Interestingly some arm consts have changed (arm/i386 abi difference?).

Add some mode /dev/nodes*
Add anoter midi device.
