Add open callback if there are no other unique callbacks.
This happens for e.g. seq files which only have unique open,
while read is a common seq_read callback.
|

|

Use resolved Function references instead of string names for fileops
callback resolution. Function names are not unique, a number of callbacks
have the same names.
|

Currently we misparse some function references, e.g. for:
.write = (foo) ? bar : baz,
we extract "foo". Extract first function reference from such expressions.

Some ioctls are declared inconsistently using enums rather than macros.
Extract these as well.

Add coverage percent for kernel interfaces.
The current data is generated with Mar coverage report
on kernel commit 1e7857b28020ba57ca7fdafae7ac855ba326c697.

Export each syscall variant (e.g. fcnt$*) as a separate interface.
Effectively these are separate syscalls. We will want this for
ioctl as well (it's not 1 interface).

Extract info about function scopes formed by switch'es on function arguments.
For example if we have:
void foo(..., int cmd, ...)
{
...
switch (cmd) {
case FOO:
... block 1 ...
case BAR:
... block 2 ...
}
...
}
We record that any data flow within block 1 is only relevant
when foo's arg cmd has value FOO, similarly for block 2 and BAR.
This allows to do 3 things:
1. Locate ioctl commands that are switched on within transitively
called functions.
2. Infer return value for each ioctl command.
3. Infer argument type when it's not specified in _IO macro.
This will also allow to infer other multiplexed syscalls.

The check did not actually match any header files.
Fix the check.

syz-declextract accumulated a bunch of code health problems
so that now it's hard to change/extend it, lots of new features
can only be added in in hacky ways and cause lots of code duplication.
It's also completly untested. Rewrite the tool to:
- move as much code as possible to Go (working with the clang tool
is painful for a number of reasons)
- allow testing and add unit tests (first layer of tests test
what information is produced by the clang tool, second layer
of tests test how that information is transformed to descriptions)
- allow extending the clang tool output to export arbitrary info
in non-hacky way (now it produces arbitrary JSON instead of a mix
of incomplete descriptions and interfaces)
- remove code duplication in the clang tool and provide common
infrastructure to add new analysis w/o causing more duplication
- provide more convinient primitives in the clang tool
- improve code style consistency and stick to the LLVM code style
(in particular, variable names must start with a capital letter,
single-statement blocks are not surrounded with {})
- remove intermixing of code that works on different levels
(currently we have AST analysis + busness logic + printfs
all intermixed with each other)
- provide several helper Go packages for better code structuring
(e.g. pkg/clangtool just runs the tool on source files in parallel
and returns results, this already separates a bunch of low-level
logic from the rest of the code under a simple abstraction)
I've tried to make the output match the current output as much as possible
so that the diff is managable (in some cases at the cost of code quality,
this should be fixed in future commits). There are still some differences,
but hopefully they are managable for review (more includes/defines,
reordered some netlink attributes).
Fixed minor bugs are fixed along the way, but mostly NFC:
1. Some unions were incorrectly emitted as [varlen]
(C unions are never varlen).
2. Only a of [packed], [align[N]] attributes was emitted
for struct (both couldn't be emitted).

Update to upstream commit 228a1157fb9f.
VFIO_TYPE1_NESTING_IOMMU const was removed in 35890f85573c.
Remove it from descriptions.

One line per interface allows to use all power of unix utilities
to process these files. For example the following command
allow to select all unpriviledged interfaces present in one kernel
but not in another:
comm -23 <(cat auto1.info | grep access:user | cut -f -2 | sort) \
<(cat auto2.info | cut -f -2 | sort)
