2019-08-06osmo-release.sh: Drop whitespace after = when parsing LIBVERSIONPau Espin Pedrol2-2/+2
As a result whitespace ended up in some variables and then command "expr" was not happy about it. It was spotted because src/coding/Makefile.am had some whitespacing. Since it's the only one, let's drop the whitespace there too to have similar line in all Makefile.am files. Change-Id: I33afef5e4ef9eb36de81274533f46598ba9a0edb
2019-08-06configure: Allow disabling workaround for TLS bug in old ARM gcc versionsPau Espin Pedrol2-2/+23
Some toolchains (such as sysmobts 201705 one) containing the TLS bug on old ARM gcc versions (<7.3.0) also crash if the initial workaround found is aplied (CFLAGS="-mtls-dialect=gnu2"). In that scenario, let's provide a way to disable the workaround (to avoid "ld" crashing) and warn the user about requirement to build with -O0 to avoid runtime crashes.

2019-08-06configure: Autodetect TLS bug on ARM with old gcc and apply workaroundPau Espin Pedrol2-0/+33
Check if compiler being used contains the bug. GCC 7.3.0 is the oldest version containing the fix, and version 6.3.0 is known to contain the bug. Bug is only known to appear so far only on ARM32. If the bug is present, gcc will generate a wrong binary which wil lend up segfaulting when accessing TLS (__thread) variables under certain conditions.

2019-08-05tests: logging: Remove undefined param passed to logging_vty_add_cmdsPau Espin Pedrol1-1/+1
Since March 15th 2017, libosmocore API logging_vty_add_cmds() had its parameter removed (c65c5b4ea075ef6cef11fff9442ae0b15c1d6af7). However, definition in C file doesn't contain "(void)", which means number of parameters is undefined and thus compiler doesn't complain. Let's remove parameters from all callers before enforcing "(void)" on it. Related: OS#4138 Change-Id: Iaea795521361a8e5b3b45eaeb35e6eda69163af3
2019-08-02Get rid of osmo_str_tolower() use inside libosmocore codePau Espin Pedrol1-11/+13
There's no real good reason for using that function (static buffer) instead of osmo_str_tolower_buf(local buffer), so let's use the later. In any case, we get rid of TLS variables in those places, which is a performance improvement. It will also allow later shrinking of those buffers if we decide to define maximum logging category and level name length. Change-Id: I2e99de1142020e4d80ef0a094e4e751f7903f5f9
2019-08-02utils: share static buffer in osmo_str_to{lower,upper}()Pau Espin Pedrol1-8/+8
This way we get rid of extra 128 bytes in memory per thread created. It makes sense to share the buffer since it's same size and it doesn't make much sense to be using both osmo_str_tolower and osmo_strtoupper at the same time (usually you either want to move everything to uppercase or everything to lowerase). In required scenarios, one can still use the _buf versions. Change-Id: I032803faa0e27c2efdff1ff276acabab95a8319a

2019-07-30vty/vty.c: fix vty_read(): prevent further heap-buffer overrunVadim Yanitskiy1-0/+2
After reading data from the socket, assigned to a given VTY, we need to '\0'-terminate the received string. Otherwise, further access to that string, stored in a heap buffer vty->buf, would lead to a heap overrun. == How to reproduce? $ python -c "print 'A' * 512" | telnet $HOST $PORT ==21264==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x6190000211e0 at pc 0x000000435d2f bp 0x7ffc06c7add0 sp 0x7ffc06c7a578 READ of size 1025 at 0x6190000211e0 thread T0 #0 0x435d2e in __interceptor_strlen (/usr/local/bin/osmo-msc+0x435d2e) #1 0x7fb95bfa5624 in talloc_strdup (/usr/lib/x86_64-linux-gnu/libtalloc.so.2+0x6624) #2 0x7fb95c1be2bc in vty_hist_add /opt/osmocom/libosmocore/src/vty/vty.c:578 #3 0x7fb95c1be2bc in vty_execute /opt/osmocom/libosmocore/src/vty/vty.c:703 #4 0x7fb95c1be2bc in vty_read /opt/osmocom/libosmocore/src/vty/vty.c:1425 #5 0x7fb95c1bfd78 in client_data /opt/osmocom/libosmocore/src/vty/telnet_interface.c:157 #6 0x7fb95b90bd33 in osmo_fd_disp_fds /opt/osmocom/libosmocore/src/select.c:223 #7 0x7fb95b90bd33 in osmo_select_main /opt/osmocom/libosmocore/src/select.c:263 #8 0x5006cc in main /opt/osmocom/osmo-msc/src/osmo-msc/msc_main.c:723:3 #9 0x7fb959935f44 in __libc_start_main /build/eglibc-xkFqqE/eglibc-2.19/csu/libc-start.c:287 #10 0x4226fb in _start (/usr/local/bin/osmo-msc+0x4226fb) == Why exactly 512? Because the initial size of the heap buffer is 512 (see VTY_BUFSIZ). Later on it can be realloc()ated, so X > 512 should also work. Found using AddressSanitizer and Radamsa [1] fuzzer.

Unfortunately, osmo_sock_get_name_buf() fails in telnet_close_client(): DLGLOBAL INFO telnet_interface.c:130 Closing telnet connection <error-in-getsockname> because getsockname(), getpeername(), and even close() fail with: "Bad file descriptor".

2019-07-30gsm0808_test: Fix wrong use of memcpPau Espin Pedrol1-1/+4
After recent system upgrade, gcc 9.1.0, I started getting gsm0808_test failing locally: Assert failed memcmp(&enc_ct, &dec_ct, sizeof(enc_ct)) == 0 libosmocore/tests/gsm0808/gsm0808_test.c:992 During investigation with gdb, fields of both structures seem to contain same values. However, closer lookup gives some hints on why it fails: (gdb) print memcmp(&enc_ct, &dec_ct, sizeof(enc_ct)) $1 = 85 (gdb) print memcmp(&enc_ct, &dec_ct, 12) $14 = 85 (gdb) print ((uint8_t*)&enc_ct)[11] $15 = 85 'U' (gdb) print ((uint8_t*)&dec_ct)[11] $16 = 0 '\000' So the 12th byte in struct gsm0808_channel_type is basically an alignment padding byte added by the compiler (to align perm_spch_len to 4-byte alignment). Since both compared structs are initialized without memset(0) but using compiler's designated initializers, it seems the compiler decided it's no longer needed to zero the padding byte, making memcp fail in this case. In order to avoid the failure, let's properly check every field instead of using memcp here. Change-Id: I17fe7a0a5dc650f050bba1f47d071be749550729

2019-07-21tell ubsan to ignore SUN_LENEric Wild1-0/+3
ubsan will report undefined behavior due to the SUN_LEN macros interaction with a null pointer, so let's tell ubsan to ignore this function. After carefully reviewing the final publically availlable drafts of the C99,C11 and C18 standards I can confirm that dereferencing null pointers is still undefined behavior, as such ubsan will always warn with absolutely every existing compiler version. Since the sanitizers are periodically synced between llvm and gcc I'm also fairly confident that rebuilding everything with compiler_rt to use the integrated sanitizers would result in the same message. I sincerly hope that this explanation provides to be sufficient, If not I'd be willing to show up at the next llvm dev meeting to provide quotes from actual sanitizer developers to back up these claims.

2019-07-20cbsp: Introduce osmo_cbsp_errstrHarald Welte3-28/+102
Rather than having the encoder/decoder library print some log messages in case of encoding/decoding errors, let's provide something akin to 'errno', but with a string instead of a numeric error code. The 'osmo_cbsp_errstr' global variable (if set) contains a human-readable string describing the most recent encoding/decoding error. It exists separately for each thread and hence can be used safely in multi-threaded environments. Change-Id: Id9a5a595a76ba278647aee9470ded213d8464103

The link quality, defined by C/I (Carrier-to-Interference) ratio, can be computed from the training sequence of each burst, where we can compare the "ideal" training sequence with the actual training sequence and then express that in cB (centiBels, dB * 10). By analogy with both RSSI and ToA, it can be used to filter out false-positive detections and ghost Access Bursts. Change-Id: Ie2a66ebd040b61d6daf49e04bf8a84d3d64764ee
2019-07-09Revert "utils.h: require a semi colon after OSMO_ASSERT"Vadim Yanitskiy1-2/+2
This reverts commit 4e284b637943980a405a8c44f2712b749ded428f. Unfortunately, some projects such as OsmoMSC, OsmoBTS and OpenBSC do contain OSMO_ASSERT statements without a semi colon. Thus, this change causes compilation errors when building them. Please note that only the OSMO_ASSERT's definition is reverted, while changes to other files (adding missing semicolons) are kept.
