deduplicate generic type arguments

[kkourt]

There are two versions of generic type arguments:

tetragon/pkg/generictypes/generictypes.go

Lines 6 to 36 in 3076ae7

	const (
	GenericIntType = 1
	GenericCharBuffer = 2
	GenericCharIovec = 3
	GenericSizeType = 4
	GenericSkbType = 5
	GenericStringType = 6
	GenericSockType = 7
	GenericCredType = 8
	GenericS64Type = 10
	GenericU64Type = 11
	GenericS32Type = 12
	GenericU32Type = 13
	GenericFilenameType = 14
	GenericPathType = 15
	GenericFileType = 16
	GenericFdType = 17
	// GenericConstBuffer is a buffer type whose size is static (and known).
	GenericConstBuffer = 18
	GenericBpfAttr = 19
	GenericPerfEvent = 20
	GenericBpfMap = 21
	GenericUserNamespace = 22
	GenericCapability = 23
	GenericNopType = -1
	GenericInvalidType = -2
	)

And

tetragon/pkg/selectors/kernel.go

Lines 140 to 159 in 3076ae7

	const (
	argTypeInt = 1
	argTypeCharBuf = 2
	argTypeCharIovec = 3
	argTypeSizet = 4
	argTypeSkb = 5
	argTypeString = 6
	argTypeSock = 7
	argTypeS64 = 10
	argTypeU64 = 11
	argTypeS32 = 12
	argTypeU32 = 13
	argTypeFile = 16
	argTypeFd = 17
	argTypeUrl = 18
	argTypeFqdn = 19
	)

There seem to already be conflicts, so we should deduplicate them.

Hey @kkourt Can I work on this issue? I am pretty new to tetragon, this would be good first issue for me.

Hi @rajaSahil,

Go ahead if you want. I'm not aware of someone else working on it at the moment.
Thanks!

For info there is potential progress here #696 but no response from the author yet.

[mtardy]

There was a first attempt here #696 that was abandoned, I'll close the PR for now but this can be of inspiration for someone that wants to complete that :)

[Trung-DV]

This issue already solved by PR #2168

[mtardy]

Indeed thanks!
