2022-11-03Support building with -Werror=strict-prototypes / -Werror=old-style-definitionHarald Welte1-1/+1
Unfortunately "-std=c99" is not sufficient to make gcc ignore code that uses constructs of earlier C standards, which were abandoned in C99. See https://lwn.net/ml/fedora-devel/Y1kvF35WozzGBpc8@redhat.com/ for some related discussion. Change-Id: I79c51b78d1b055361f9ef5434361847353791d0d

2022-08-24gtlv: check memory bounds 1/3: encoding TLVNeels Hofmeyr1-1/+2
Introduce a maximum bound of memory access to the osmo_gtlv API. Properly pass const-ness within the gtlv implementation. This patch adds membof_const(). The following patch will add the non-const membof() equivalent, which is not needed in this patch, yet. Coverity CID#275417 drew my attention to the fact that the gtlv decoding and encoding does not actually guard against access past the end of the decoded struct. We have not yet officially released libosmo-gtlv; also, osmo-upf and osmo-hnbgw so far only use the libosmo-pfcp API, which "hides" the gtlv API. Hence just change the API without a backwards compat shim. Related: CID#275417 Related: SYS#5599 Change-Id: Id8d997c9d5e655ff1842ec69eab6c073875c6330
2022-06-16libosmo-gtlv: add TLIV capabilityNeels Hofmeyr1-9/+9
During code review, it was indicated that some TLV protocols that we will likely deal with in the near future also employ an I, and instance value of a tag. Add TLIV support. A usage example for a manually implemented TLIV structure is found in tests/libosmo-gtlv/gtlv_test.c. A usage example for a generated TLIV protocol is found in tests/libosmo-gtlv/test_tliv/.

2022-06-16libosmo-gtlv: add auto dec/enc to/from structsNeels Hofmeyr1-0/+422
Add osmo_gtlv_coding: describe the value part of a TLV (decode and encode), describe a struct with its members, and get/put readily decoded structs from/to a raw PDU, directly. With osmo_gtlv_coding defined for a protocol's tags, we only deal with encoded PDUs or fully decoded C structs, no TLV related re-implementations clutter up the message handling code. A usage example is given in gtlv_dec_enc_test. The first real use will be the PFCP protocol in osmo-upf.git. With osmo_gtlv_coding, there still is a lot of monkey work involved in describing the decoded structs. A subsequent patch adds a generator for osmo_gtlv_coding and message structs from tag value lists. Related: SYS#5599 Change-Id: I65de793105882a452124ee58adb0e58469e6e796
