2018-12-05contrib/jenkins.sh: build and publish manualsOliver Smith1-2/+20
Add new environment variables WITH_MANUALS and PUBLISH to control if the manuals should be built and uploaded. Describe all environment vars on top of the file. When WITH_MANUALS is set, install osmo-gsm-manuals like any other dependency and add --enable-manuals to the configure flags (for "make" and "make distcheck"). Add the bin subdir of the installed files to PATH, so osmo-gsm-manuals-check-depends can be used by ./configure. Related: OS#3385 Change-Id: I43e3b592c593237eb4df2d70c926c031ddb7b20b

2018-11-27refactor Makefile build rules, don't use the FORCENeels Hofmeyr1-35/+6
The initial goal was to make sure we don't have overall FORCE rules causing unnecessary rebuilds -- annoying while writing documentation. As I looked through possible dependencies, I finally understood what's going on here. Remove code dup and nicely sort which belongs where in build/Makefile.*.inc. In each, describe in a top comment how to use it, and also unify how they are used: - Rename Makefile.inc to Makefile.docbook.inc and refactor - Add Makefile.vty-reference.inc - Add Makefile.common.inc Make sure that we accurately pick up all dependencies. Drop use of the macro called 'command', that silenced the actual command lines invoked and replaced them with short strings: it obscures what is actually going on and makes the Makefiles hard to read and understand. Each manual's makefile is greatly reduced to few definitions and a Makefile include, e.g. one for asciidoc, one for VTY reference. Move common/bsc_vty_additions.xml to OsmoBSC/vty/libbsc_vty_additions.xml, link from OsmoNITB. It applies only to OsmoBSC and OsmoNITB. Add a script that combines a VTY reference file with *all* additions files found in a manual's vty/ dir. Call this from Makefile.vty-reference.inc.

2018-11-22properly store IPv6 addresses in struct tun_tStefan Sperling3-10/+17
All addresses in struct tun_t were stored as an in_addr. But IPv6 addresses need an in6_addr, so switch tun_t addresses to the in64_addr wrapper struct. This is an ABI break, as documented in TODO-RELEASE. Fixes an out of bounds memcpy() identified by Coverity. Change-Id: Idd2431ad25d7fa182e52e2bd5231ceb04d427c34 Related: CID#174278

2018-11-22replace bogus memcpy() call in ippool_newip()Stefan Sperling1-1/+9
When copying an address to a reused static hash table member with memcpy(), this code mistakenly passed the size of a pointer as the amount of bytes to be copied, rather than the actual size of the address. This means the IP pool could contain bogus IP addresses because only addr->len (a uint8_t) and 3 further bytes of the address were actually copied on 32 bit platforms. On 64 bit platforms, a sufficient amount of bytes were copied for IPv4 to work correctly, but too few bytes were copied for IPv6. This problem was found by Coverity. Replace the bogus memcpy() call with direct assignments to the appropriate struct in64addr union members, and assert that the length recorded for the address actually corresponds to the length used by the address family (IP4, IPv6).

2018-11-22fix allocation of ippool's hash tableStefan Sperling1-3/+2
The calloc() call in ippool_new() had two problems. The first problem is benign: The order of arguments were reversed. Pass the number of elements in the array first, then the size of each element, as calloc() expects. This problem was found by me. There are more instances of this problem in this file, which I'll address in follow-up patches. The second problem is that the requested allocation was larger than necessary: The hash table is an array of pointers to ippoolm_t, not an array of struct ippoolm_t. Fix the required size passed to calloc(). This problem was found by Coverity. Change-Id: I93fa5bc539771ca19714f6a665558c9140e2ce07 Related: CID#57920

2018-07-21gtp: Add new API to avoid freeing pdp contexts during DEL CTX REQPau Espin Pedrol2-37/+73
With this API, user is expectd to free the PDP ctx when the confirmation for the release has been received (cb_conf time). This way user can maintain the pdp ctx alive during all this time. Extra code is added to gtp_delete_pdp_resp() since it's now possible to match it and push it up to the user cb_conf. This way, cb_conf() can be used for locally-initiated DEL CTX REQ, while delete_context() cb is left for remotely-initiated DEL CTX REQ. In this later case, when the DEL CTX RESP is sent the ctx is deleted and the delete_context() is called, where the user can do related actions or trigger consequence events (in the case of SGSN, it will drop all related GGSN bits for that PDP ctx and forward the DEACT PDP CTX to the MS).

2018-07-19fix unaligned access in build_ipcp_pco()Stefan Sperling1-20/+31
IPCP data can begin at any byte location in the pco_req->v array. Casting to a 'struct ipcp_hdr' pointer could lead to unaligned access. Parse IPCP data with u_int8_t pointers instead to avoid this problem. Add some length checks while here. pco_contains_proto() and ipcp_contains_option() now receive the minimum size of the data the caller is looking for, and only return pointers to items of sufficient size. Also fix an inifinite loop in ipcp_contains_option() by refusing IPCP options with length small than 2. Previously, a zero length option would trigger an infinite loop in the parser.

2018-05-28ggsn: fix misinterpreted length field in ipcp_contains_option()Philipp Maier1-1/+1
The abort condition of the while loop in ipcp_contains_option() is accessing ipcp->len directly. Unfortunately this field is an uint16_t which as to be interpreted as little endian value. If it is used without prior conversion the value may appear larger than actually intended and the loop will then not stop at the end of end of the buffer. This can cause unpredictable results when the value given with the parameter enum ipcp_options opt is not found. The loop will then eventually cause a segmentation fauld or is likely to hang as soon as cur_opt->len points to a zero byte in memory. - Make sure that ipcp->len interpreted correctly by accessing it through ntohs() Change-Id: Icffde89f9bc5d8fcadf6e2dd6c0b4de03440edd5 Related: OS#3288
