+Subject: MIPS: Avoid a dangling `vfork@GLIBC_2.0' reference
+X-Git-Url: https://sourceware.org/git/?p=glibc.git;a=commitdiff_plain;h=c14e752fc73d34c75d4f84f37fea8e0b1734cf98
+
+MIPS: Avoid a dangling `vfork@GLIBC_2.0' reference
+
+This satisfies a symbol reference created with:
+
+ .symver __libc_vfork, vfork@GLIBC_2.0
+
+where `__libc_vfork' has not been defined or referenced. In this case
+the `vfork@GLIBC_2.0' reference is supposed to be discarded, however a
+bug present in GAS since forever causes an undefined symbol table entry
+to be created. This in turn triggers a problem in the linker that can
+manifest itself by link errors such as:
+
+ld: libpthread.so: invalid string offset 2765592330 >= 5154 for section `.dynstr'
+
+The GAS and linker bugs need to be resolved, but we can avoid them too
+by providing a `__libc_vfork' definition just like our other platforms.
+
+ [BZ #17485]
+ * sysdeps/unix/sysv/linux/mips/vfork.S (__libc_vfork): Define.
