From: Preeti Sachan <[email protected]> libfastjson is missing an explicit link dependency on the math library (libm), which triggers GNU Indirect Function (IFUNC) resolution failure at runtime. libfastjson internally calls the modf() math function but modf is optimized via glibc's IFUNC mechanism. Because libfastjson was compiled without -lm, the dynamic linker (ld.so) cannot safely resolve this dynamic IFUNC redirection, causing rsyslogd to immediately crash with a segfault error. rsyslogd boot error: | starting rsyslogd ... /usr/sbin/rsyslogd: Relink `/usr/lib64/libfastjson.so.4' | with `/lib64/libm.so.6' for IFUNC symbol `modf' | rsyslogd[1311]: segfault at 9c ip Signed-off-by: Preeti Sachan <[email protected]> --- meta-oe/recipes-extended/rsyslog/libfastjson_1.2304.0.bb | 1 + 1 file changed, 1 insertion(+) diff --git a/meta-oe/recipes-extended/rsyslog/libfastjson_1.2304.0.bb b/meta-oe/recipes-extended/rsyslog/libfastjson_1.2304.0.bb index f1235d7b96..324c0cfbe8 100644 --- a/meta-oe/recipes-extended/rsyslog/libfastjson_1.2304.0.bb +++ b/meta-oe/recipes-extended/rsyslog/libfastjson_1.2304.0.bb @@ -10,6 +10,7 @@ SRC_URI = "git://github.com/rsyslog/libfastjson.git;protocol=https;branch=master SRCREV = "3a8402c1de7c7747c95229db26d8d32fb85a7a52" +EXTRA_OECONF += "LIBS='-lm'" CVE_PRODUCT = "rsyslog:libfastjson" -- 2.34.1
